- In this video I will show you a bit more complex Peltier cooling system (thermoelectric cooler). I assembled a CPU/GPU water cooling system and used it to cool the hot side of a Peltier-based cooling block which consists of 4x TEC12706-type thermoelectric cooler. I also added a temperature sensor which measures the temperature of the water at the outlet of the radiator.

I connected 2 Peltiers together in parallel connection, so they draw ~12 A at ~12 V. So, I made 2x2 Peltiers and I drive them with my DIY dual-channel power supply. If you build my power supply, you can also track the power consumption and the output voltage/current.

Thank you! This is exactly what we need to design to cool down our giant telescope mirror. It takes around 455k joules to lower the Zerodur mirror 1 degree C. Peltier cooling is a must for us! We have to route the hoses somehow, but this design will get us started! Great video.
You're welcome! I hope you'll succeed with the project. I assume you are using the telescope for astrophotography. By any chance, do you also cool the imaging sensor with something? I am just curious.
I m also a hobbiest, I am from Delhi capital of India. I saw your video today for the first time. and I swear I have never seen such a nice, compact, concise simply but well explained video in last about ten years. You know, I hardly appreciate but your video made me honestly praise you. Really outstanding, keep it up and may almighty bless you with recognition you deserve...pritpal
Thank you very much for your kind words! It is really motivating to read these lines. I will do my best in the future.
The issue is water volume. You'll get a brief dose of cooled fluid. That said, as it cycles, it will raise overall temp.
If you wanted to go this route, buying an aquarium chiller is your best bet. These devices are huge and deal with substantially large volumes of fluid. I've seen a few running at 52 gallons. So it would take way longer to heat up that amount of fluid, meaning the chiller could potentially be able to activate and start to chill the liquid back down as it only turns on when the liquid begins to heat up.
There's two issues: the dissipation limit for the IHS being the biggest. So, in the case of say a PC water block, the cooling fins are only so big, meaning their ability to transfer a given amount of heat is fixed. So it may be possible to achieve ultra cool temps but be inhibited of further cooling simply because the IHS can't shed the heat fast enough. This could be overcome by designing bigger blocks with bigger fins by someone who's able to calculate the math figure out, fin density, and all that stuff, but that's way outside a mere plebian hobbyist.
The other issue becomes condensation forming. You'd have to seal or insulate your motherboard or circuit board to prevent water from shorting it out.
I don't want to use this system anywhere. I just demonstrated the components and their function. I am well aware of the limitations of this kind of system, and I am not using it. I use Peltier coolers in a different way for totally different applications.
(BTW, I am working on a design of a Peltier cooler-based water chiller, I am just collecting resources)
Hello I saw in some videos that a series connection of these peltiers becomes more efficient to lower the temperature and consumes less energy, have you tried to connect the 4 tablets in series for testing? Any better results?
Hi! There should be no difference assuming that your power supply can provide the power to them. If you connect it in series, each components will get the same current,but the whole circuit will require higher voltage. If they are in parallel, they are at the same potential, but the current is divided between the parts.
I assume that what you saw is the following. They connected it in series and the power supply could not provide the maximum voltage, therefore the Peltier devices were not running on max current (remember, you need to increasethe voltageto allow larger currents). Thus, they were most probably under the limit where the Joule-effect overpowers the Peltier effect, so it seemed that this way is more efficient.
Did that video provide any numbers or was it just some random connections to some random power supply?
I will actually get a more beefy power supply in the near future and provide more test result where I compare three different Peltiers. It will be a proper, scientific evaluation. Stay tuned!
@@CuriousScientist Did you get any better results ???
Check my videos. You are asking a follow up question for a 2 year old question. A lot of things happened since.
@@CuriousScientist amazing ..aku akan mencobanya
Thanks!
Hello Could this work as a personal cold air fan on a desk? I have a 120mm radiator and I am considering building something like this.
Hi! I recommend you to watch this video. This device is more suitable for personal air cooling: th-cam.com/video/ZDLN_tMxSQA/w-d-xo.html
I would love to build Solar Air conditioner using this. Even the cold side should have Water pump & radiator so cold Air in be placed inside the room.
Even if you only want to cool a single room, the whole system will cost you a huge amount of money mainly due to the inefficiency of the Peltiers... :(
@@CuriousScientist cost As in energy or purchase?
Peltier prices are okayish in India, about 250 rupees each. 4 of these would be 1000. Heatsinks and others will bring grand total to 3000. But regular compressor based AC costs 10x that.
4 Peltiers will not cool down your room. 40, maybe. This is the issue. And now, you are at the 10x price difference easily. 4 Peltiers are okay for keeping a small refrigerator box cold during the day.
@@CuriousScientist Its a really good idea actually.To use this system as mini split A/C (heat pump) for small grow tents, mini cigar storage room ,mini wine cellar....and so on. I've been researching this idea for days! I want to put together a mini split A/C system.Regardless of the peltier's inefficiency,its more practical for small spaces.Thanks you for posting this man! I like!
@@thedoorsbiggestfan Hi! I am glad that you like the idea! For small volumes it is usable, but many people want to fight against such a large amount of heat with Peltiers (cooling a room, a car...etc) that it will simply not work. On the other hand, you can already buy Peltier-based wine fridges, so that is for example a viable idea. If you have time, money to buy a lot of Peltiers and power supply and cooling for them, then it can work for some specific applications, but I do not advocate using this kind of cooling for things such as AC for a room or car...etc.
By the way, I am expecting to receive some new Peltiers and coolers this month, so I will put up some new, more detailed tests of several Peltiers (12703, 12706, 12708, 12710, 12715). I will do a very detailed and scientific comparison. Don't forget to subscribe to stay updated.
I am back again, to thank you for many of your videos, i completed my first system, finally! i have new question, you know those copper pipes the heatsink comes with? If i want to remove the heat from the hot side but 1. Not use the heatsink and 2. use the radiator instead
Would that work/ be efficient? And if you were to do, how would you do it?
Hi, I do not really understand it. The heat sink on this Peltier cooler block is not for cooling the hot side. Those heat sinks are simply too small for cooling. Also, based on the polarity of the Peltier coolers, the hot side is the one attached to the water cooling block and the cold side is the heat sink with the tiny fans. Precisely as I used and demonstrated it in the video.
@@CuriousScientist Thank you for replying, i understood your demonstration, my question just build on it a little bit. My current setup is using the big heatsink with fan, I was wondering if it would be more efficient if I use the radiator to cool down the hot side instead of big heatsink with fan.
If so, would the difference of surface materials between aluminum and copper be significant?
I would say that a water cooling system would be better. It depends on the budget, space availability...etc too. Copper is a better conductor, so obviously it is a better choice. However it is also much more expensive, so again it is up to your budget.
@@CuriousScientist thank you, it will be my V2 then ^^
Good luck with the project! If you want, you can keep me updated, I am interested in the results.
Hello, if I will use 4 peltiers 12706 modules what power supply I will need? It is 6A unit x 4 is 24A power supply or how to calculate? Thank you. You are good, keep doing this video is very educative.
Hi! Thank you very much for the positive words! Yes, your math is precise. Each unit is 6 A, so you need a 4*6=24 A power supply. BUT! Let me tell something. You will never be able to run these units at their specified maximum current (6 A), because the Joule effect will overpower the Peltier effect around 70-80% of the max current. Above these values, further increase in the current will heat up the Peltiers. The TEC12706 performs the best at around 4 A, so it is enough to have 4*4 =16 A power supply. But, it is always recommended to get some stronger PSU, so go for 20 A. Also, keep in mind, that these units (Peltiers in general) run at higher voltages (16-18 V) near to the max current, so you will need a power supply which is capable of 15-20 V also. If you choose a smaller one, the voltage limit will also limit the current. With this specific unit, you are lucky, because a 12 V power supply will limit the current at around 4.3-4.5 A which is nearly perfect. You can buy these LED power supplies for a very cheap price and you can modify their output to be around 13-13.5 V max by just turning a potentiometer on them. It would be a perfect choice for this 4xTEC12706 block. Also. Don't forget, that just by running them at 4 A, you generate around 4*40 W heat. This has to be dissipated on the water cooler. PLUS the heat actually pumped by the Peltiers. So prepare to have a cooler which can deal with ~300 W heat. The demonstrated water cooler is on the limit.
@@CuriousScientist Thank you, I want also want to try use 2 types of peltier 1 on top 2. Ex:on bottom heat side to use a 20715 with a CPU 8 pipes double cooling fan or water and on top of this 20706 for cooling side with aluminium 140 x 80 mm no fan, and to use a 20-30 Amps power source for cooling a fridge box. (Trikie Amps, sorry my engleash). All the best, and keep going!
@@reluaurel8077 Forget about stacking, it will not lead to better cooling performance. I made videos on this topic too. The bottom has to have high cooling power and it has to be cooled properly. Check my other videos really, I spent a lot of time on these topics.
Hi until now im still watching water chiller videos using peltier, im not good at electronics, after watching your video, i cant understand how much power supply should we use with that kind of set up, also im not sure if youve done this, how about making the cold side putting a water cooling block instead of fans for water chiller, while hot using that radiator water cooling system. Will it work as a water chiller for aquarium?
Hi! It will all come down to details such as how much water you want to cool down to what temperature and how quickly. Once you have these parameters, you can calculate the required cooling power and then you can match the Peltier coolers (type and number of coolers) to the application. Then you will know what kind of power supply you will need for the system.
BTW, building a *decent* Peltier cooler-based chiller is on my to-do list, but it is not a high-priority one since the parts would cost a lot. So maybe in the future, you'll see a water chiller video on my channel, but it will be probably in half a year or a year, depending on how much funds I can save up for the project.
Could this be use inside a computer case as a aio cpu cooler. That should be your next test
If you provide me a computer for it.. :)
Well done
Can you tell what is the order number and where did you buy it???
Thanks! All links are in the description and there's also a section on my website where you can browse these parts.
What if you removed the radiator completely and replaced it with the TEC Block? So, CPU Block -> Pump -> TEC Block -> Cpu Block. Would this be a config that could work?
EDIT: Now I get it. My apologies. I thought you were trying to make an actual water cooling solution for a PC. That being said, would the config I mentioned work for a pc closed-loop water cooling solution?
In normal cases you do not need Peltier for cooling CPUs. Why? Peltiers are useful if you want to reach temperatures _below_ the ambient temperature, as they are capable of pumping heat from their cold side to their hot side. If you do not want to go below ambient temperature, it does not make sense to add Peltiers, they would just act as a very inefficient layer between the cooler and the object that you want to cool. Furthermore, whenever you try to use Peltiers for cooling, you have to get rid of the heat you pump (so that 60-90 W from the CPU) PLUS the heat (Joule heat) generated by the Peltier cooler itself. Depending on your goal temperature, the Joule heat can easily be 2-3x more than the actual pumped heat. So at the end, you will need a serious cooling to keep everything within the specifications. Also, it does not worth to add some Peltiers to the water cooling circuit for the same reason. You still have to get rid of the heat in the circle PLUS the heat from the Peltiers. It is better to just add an extra radiator then.
@@CuriousScientist Got it. Thanks for the quick response. Love your work :)
@@ManoharOfficial Thank you for the positive feedback, I am glad you like the content!
I think if you use coolent then it will be more effective to reduce the heat from the radiator
What do you mean? There is water running inside the cooler.
Curious Scientist I am talking about coolents used in vehicles to cool the engine. Instead of water you can use coolents to cool down the peltiers
@@rajarsheedasgupta5812 Yeah, that is pretty much water (and a bit of alcohol). :D
He should have strapped another water block to the hot side and used the rad loop to cool the hot side instead of keeping it in loop with the chilled side..... its just warming the chilled fluid with ambient air.
The hot side is cooled with the water loop and the cold side which is exposed with the heat sink with the 4 fans on it. I don't know what you are talking about. Check the video more carefully. If I have done the same as you described, I could not have reached -11°C for sure. Those small heatsinks with those tiny fans could not keep up with such a large amount of heat.
عالی بود دمت گرم
What? Sorry, I can't read that.
So If I wanted to use something like this to replace a cool shirt on my motorcycle would this work?
How would you transfer the heat between your body and the Peltier coolers? Also, how would you power them and cool them? It is not that simple. Probably doable but with a lot of efforts.
hello, my advice is to separate the water block or 1 peltier 1 water block so the water block is not separated from one water halo saran saya pisahkan water block atau 1 peltier 1 water block 😊
I agree to a certain extent. If the radiator is shared, it does not really matter, because at the end, the whole system will be at the same temperature after reaching an equilibrium. On the other hand, if you cool all the Peltiers independently, with radiators for each Peltiers, it might give better results. But for these small performance Peltiers, it doesn't really worth the struggle, one common system is sufficient.
@@CuriousScientist please translate in Indonesia😊
So this means that you were trying to use the peltier to heat up the water but use the radiator to cool down the water temperature?
If this is the case what would you say the efficiency of the radiator removing the heat?
Also can you do one with using a closed water block system to "remove" the heat from the peltier?
No, in this experiment, I used the Peltiers to cool down the heatsink with the cold side and I used the water cooling system to cool the hot side of the Peltier coolers. Check my channel, I have plenty of Peltier cooler-related experiments. By the way, I am not fulfilling requests for free.
@@CuriousScientist For free? So I guess someone was paying you all this time? Look man, if you felt that I was commanding you to do about my question, I apologize, I was not commanding. It was just a question, if you don't want to do it then may be you could have given me a prediction. Anyway it's your channel.
Yeah, it felt like a bit of a request. Sorry, if you did not mean like that! But really, check my other videos because the thing that you asked for is already done and I discussed it. Maybe this video would be interesting: th-cam.com/video/760qWkUTlp8/w-d-xo.html
Hello. I am thinking about using heat sink and pipes to cool the water and put a fan in front of cooled heat sink to make it blow cool air in my face. That's it, I know that it is not possible to cool whole car but I'd like to have at least my face cool. Hot air exhast would be another water bucket or fan and pipe leading outside through window. Does this application make any sense?
Hi! Check my most recent Peltier-related video. I do something very similar there and I also discuss why it did not work. In a nutshell you will need a lot of energy to keep the heatsink cold enough that you can blow noticeably cold air from it. It is not impossible, but it is not too feasible.
Can this setup integrate with a water to air inter cooler ?
Yes, but if you are planning to integrate it in a car, it will not work very well. Peltier coolers are not for that kind of use. Also, as far as I know, the temperature in the system is really high (150°C ?), which is a bit too hot for Peltiers. So, while physically, nothing hinders it, but it is not a very feasible idea.
Is it okay use 2x 240mm radiator for 4x peltier with 160mm water block?
I have a project Oil Cooler for my Motorcycle with 4x peltier and 160mm water block for engine oil, so the hotside peltier goes to 2x 240mm radiator and coldside goes to engine oil.
Thanks
Sorry for bad english ✌🏻
Hi! Using Peltier (or any other) active cooling to cool the oil of vehicles is not a great idea. I could be wrong but as far as I know, the oil (and water too) is always cooled passively. It makes no sense for me to use Peltiers to cool the oil system of a motorcycle. Active cooling is only useful when you want to go below the ambient temperature. I think, oil is doing fine even at 90-100°C.
@@CuriousScientist okay, thanks for your explanation. Maybe i'll just use convensional Oil Cooler.
Thank you 😄
Much cheaper and better solution! Once again, as long as you are allowed to stay above the ambient temperature, you don't need Peltier coolers or compressor-based ones...etc. A large radiator and a fan to increase the airflow is just enough.
Why do you need the radiator and the peltier? Don't they both serve the same purpose?
Hi Mike! The radiator takes away the heat from the hot side of the Peltier. The purpose of it is just to keep the hot side near the room temperature. The purpose of the Peltier is to cool down the heatsink to some below zero temperatures. Imagine the Peltier as a simple pump, but instead of water the "medium" is the heat. You have a bottle of water in an insulated box which is in contact with the cold side of the Peltier. The Peltier first cools down the air in the box, then the water bottle is being cooled down by the colder surrounding air (the heat from the warmer object goes to the colder (water warms up the air)) . This excess heat is pumped out by the Peltier from the cold to the hot side, and then the radiator is used, to carry away the heat from the hot side.
Can you power the same system with a power bank ? Do you have a small cooling system for a small box 📦
I don't think you could have enough power in a regular power bank. We're talking about several hundred watts here. You'd need a decent battery to run this for a longer time.
@@CuriousScientist do you suggest any other way to cool a small box with orange pi other then fans ?
What's wrong with fans? And why would you want to cool it with Peltier coolers? They are useless in this scenario, unless you want to cool it below room temperature... just use a proper heatsink and a fan.
to make a chest freezer with the size of 60cm x40cm x 40cm, how many peltier it is needed ??? what are the volts and amperes for the PSU?
I cannot guess. It all depends on the cooling speed you want, the cooling that you can provide for the hot side, what is your budget...etc. Watch my videos, I did a lot of very detailed experiments and then you will be able to figure it out.
@@CuriousScientist is using 8x tec 12706 enough for the dimensions of 60cm x 40cm x 40 cm?
You still haven't provided enough details... I would _guess_, yes, it would be enough, but I don't know what kind of results you should expect. 8 of this Peltier is 8 x 65 W = 520 W cooling power, but since you want some temperature difference too, it is more like 200W. Also, these units need around 80-100 W power each (~5-6 A x 16 V). But you won't run them on max performance of course, so let's say 50 W per unit. So, you will need a total of 200 W + 400 W = 600 W cooling on the hot side of the Peltier. If you are planning to use this inside, prepare for some raise in the room temperature. :) Also, you will need some bulky power supply, or several smaller. You want them to be capable of 15-20 V output at least and the the amount of current depends on your wishes.
I tell you once again. Don't just ask and expect to be fed with the answers. That is the lazy way and will never work. Watch my videos and educate yourself. You will gain more from that.
How come you can not just mount the peptides right to the radiator enough to cover the whole radiator wouldn't that keep the water cool ? Then mount fans in the front pulling the cool air though.
Just looks to me that would out a lot of confusion.
And how would you cool the Peltiers?
I know this video is abit older but:
The fans of the radiator are blowing to the peletiers.. so you are blowing warm air through the peletiers. You should turn around the fans
Why does that matter? I was just testing the cooling system. So it is irrelevant. Actually, it is even better because the Peltiers had to pump more heat, so more heat ended up in the water cooler loop.
why do you have the 4 fans blowing on the cold side of the peltier?
This is how they sold the units. But it makes sense. If you don't use all the fans, ice starts to build up on the heatsink which means that the heat is not transferred properly from the volume that we want to cool with the cooler.
@@CuriousScientist Thanks for the reply. Can I just ask how much water were you testing with in this experiment?
If you are talking about the water inside the water cooler system, it is about 5-800 ml.
@@CuriousScientist ive just built something similar to you. But im trying to cool a small fish tank down of 25 litres. The system we have built works but it loses its efficiency once the amount of water needed to be cooled increases. Have you had any experience trying to cool large amounts of water/have any tips?
Any would be appreciated.
It is hard to point out the reasons because there are so many variables in these systems. Check this video for some ideas: th-cam.com/video/J3k4zdX9S4Y/w-d-xo.html
How do you cool the Peltiers? How do you transfer the heat between the cold side of the Peltier and the water? How many and what kind of Peltiers do you use? At what voltage/current? What are your expectations regarding cooling speed and stability (will you add 10 liters of warm water all of a sudden to the system or you just want to cool the 25 l down to a certain temperature and keep it there)? So yeah, there are so many questions. :)
in 12vdc 4pcs. Peltier module howmany watts will consumed?
You can check that by reading the performance chart of the TEC12706. It is around 200-250 W, depending on the value of DT (temperature difference between the hot side and cold side).
Hello, 👍👍👍👍 fan rpm????
Hi! I do not know, it is not stated in the description, nor written on its package. Since it is a 12 cm fan, I guess, it has a relatively low RPM, maybe around 800-1200 RPM, because it is not too noisy...
Hola tengo una duda que diametro tienen las mangueras ? Gracias
Hi! I don't know if you have noticed, but the language of the video is (broken) English. If you expect help or response, please at least write in English.
I am just guessing from the "diametro" that you are curious about the pipes. They are 8 mm "diametro".
@@CuriousScientist thank you :)
can this works if I only use a water loop to cool it without any fans, will it get too hot
I would say, it would not work. The water is not doing any cooling, the water is used to transport the heat from the hot side of the Peltier cooler to the radiator where the hot water releases its heat into the air with the help of the radiator and fans. We need the radiator to increase the surface area where the hot water can interact with the room temperature air, and we need the fans because we want to increase the airflow, so the hot water can interact with a larger volume of fresh air at a time.
@@CuriousScientist thanks for ur rply👍
I am glad that I could help!
Is it good as an air cooler?
Depends on a lot of variables. In short, no. These devices are very inefficient. If you want to make something comparable to the traditional air conditioners, you will end up paying a lot because of the power supply, cooling and the power bill. I do not recommend Peltier coolers for cooling air. By the way, check my recent videos. I am testing a lot of different Peltier devices. Hopefully, you will learn a lot from those videos.
@@CuriousScientist Hey, thank you for sharing your knowledge on these videos! Do you think it would still be inefficient on a small car? Assuming the use of 2 to 3 peltiers, where in my case I have a lot of amperes left to use (40). Thank you!
@@PaulaKonrathFleck You are welcome, I hope you found them useful! I just express my opinion, so I might be wrong, but I base my opinion on my experience and knowledge: So, I think, car is a very challenging environment for this. There are several heat sources and a lot of inefficiencies in thermal insulation. 40 A is actually not too much. If you think about it, 1 TEC12715 can take 15 A when it is cooled properly while pumping about 200 W of heat. To match a car's AC, which is consuming typically 2-3 kW and producing 10-12 kW cooling power, you will need 40-60 of these Peltiers. This comes from the fact that Peltier coolers are about 3-4 times less efficient in converting the invested power into cooling power. This is just a "back on the envelope" calculation, but if you really calculate it, you will get similar conclusions. It does not worth it. You will need much more power for the Peltiers and you have to cool those Peltiers very well. A lot of cabling, cooling...etc. Just buy a compressor-based AC. Peltiers are not for air conditioning. I have a video on this exact topic, look it up on my channel.
@@CuriousScientist Thank you for the extended explanation! :)))
You are welcome!
OK... TQ... 👍🙏😷
You are welcome!
Can I make peltier air-conditioner..?
Water chilled air-condition
Short answer, no, you can't.
Longer answer. If there are no limitations, you can. You will need a large amount of Peltiers, and then something that removes the heat from the hot side of the Peltiers. Then, you will need a lot of money to buy these Peltiers (we are talking about something in the order of magnitude of ~50 pieces...), and you will also have to pay very high electricity bill, since these are very inefficient coolers. It is not designed to make them into air conditioners. Compressor-based AC is the way.
So, again, in practice, it is not impossible to build one, but it is very impractical!
@@CuriousScientist Hello sir. I have a question about what you said here. What if I isolate the heat part of the peltier from the cold area? I mean, let's assume that I am using 5 peltiers between 2 aluminium water blocks and they exist outside. Then, I am taking the cold water into a radiator in my room from the cold aluminium block which is outside by using a pump through a pipe. Will it be efficient?And about the hot part I am also using another radiator outside connected to a fan to reduce the heat. Thank in advance!
@@metekaba6532 Even, if you carry away the heat properly, like it is done in the case of a regular AC, where you have the cooler of the hot stuff outside the house, it would not work. Peltiers are not made for air conditioning. This particular kit has 4 TEC12706 in it. Each of that unit has a maximum cooling power around 70-72 W. With zero temperature difference on the two sides. Let's say, you can keep the hot side at ambient temperature (35°C), then you need around 15-20°C temperature difference between the two sides. You can provide roughly 45-50 W cooling power per unit, so let's say 200 W total. A regular AC provides ~2000 W. So you need 10 of this 4xTEC12706 unit. Good luck cooling it and providing the enormous amount of power to them. Also, it is pretty sure, that you cannot maintain such a low temperature (35°C) with the 4-unit water cooled block on the hot side. This means that the cooling performance would be even lower.
@@CuriousScientist Thank you for this great explanation! Let me give you a secret that nowadays I was trying to do such project for my small room but I believe that your idea is enough to abort the project :)))) Now I am thinking what to do with these 5 peltiers. I think making a mini refrigerator is possible by using peltiers. Isn't it? Or, what else can I do by using peltiers? Everyone says that peltiers takes a lot current and spends a lot energy so what is the point to manufacture them? I believe that there can be a valid project to use them. Thank in advance and have a great day!
@@metekaba6532 You are welcome, I am very happy to participate in such discussions! Yes, Peltiers take a lot of current and provide very little cooling in exchange. You should check my "Let's discuss about Peltier cooling" videos. I talk about these things. A mini fridge would be great, but you have to keep in mind that it will cool the content slowly. But if you want to have a few bottles of water in it and keep them cool, that could work. Also, Peltiers are good if you want to cool something directly attached to its cold side below ambient temperature. Some special sensors and detectors which are made of semiconductors need to be cooled down below room temperature. Peltier's are good for this. For example the silicon detectors in some scanning electron microscope equipment (EDS) are cooled with Peltiers. Peltier "forces" the heat through itself from the cold side to the hot side. So, it works like a waterpump. Check my recent videos where I talk about this and you will understand how you can utilize the Peltiers to the best.
what will happen if u put peltier with fan and heatsink on radiator?
I don't entirely understand your question. Put it directly to the radiator, or what do you mean?
@@CuriousScientist what will happen if peltier put on any side of the radiator? better temperature or worst?
Why would you put a Peltier on the radiator? You will need to cool those Peltiers too. It does not make sense. The heat does not appear from the Peltiers, it just being pumped from one side to the other.
I Imagine this set up but in the oppsite way. To cool down the water running in the system to cool down other components lets say in a computer
As long as you don't want to go below the ambient temperature, it does not make any sense. You still have to cool the hot side of the Peltier coolers.
I would like to see that as well. Cooling the water which then can cool a CPU or GPU. Could you test how low the water temperature could get with this setup?
Check my most recent video about Peltier cooling. It is a very difficult task and as I said, if you don't want to go below ambient temperature, it doesn't make any sense.
@@CuriousScientist checked on the most recent videos and I am not sure which one you are referring to. Yes, I would absolutely like to go below ambient. I actually would like to go below zero, if possible. This could be used for Overclocking, benchmarking, performance testing and gaming.

This one is the most recent. If you want to go below zero, forget about any kind of liquids. You just introduced an additional thermal resistance into your system. Mount the Peltier directly on the heat source. But, you will need a very large performance Peltier, especially if you are overclocking. It will be crazy expensive. It is not an easy task to remove 3-4-500 Watts (VGA) of heat with Peltier coolers. And then this system will need a very powerful cooling as the Peltiers create a lot of heat too.
Hey, I want to make peltier AC for a small room, same build as you did. But question is: Should I use single 40x120 waterblock with 4xTEC, or should I use 4x 40x40 waterblocks and seperate them and connect tubes in sequence? Maybe it's better to have them seperated for better cooling or there would be no difference?
Hi! None of the above configurations will cool down your room. The system I built is not capable of air conditioning due to its very low performance. Peltier coolers in general are not made for air conditioning due to their low efficiency.
Is it ready made kit please send me link
Price disscus me
Hi Bharat! You should read the description more carefully next time. Each product is given in the description with a link. This is not a ready made set, but you can buy all the individual components by using the links in the description. The water cooling is one single kit and once you have that, you just connect the Peltier block to it. Then, you need a strong power supply for the Peltier to reach some decent cooling.
Can this handle a room?
No, not at all. I have a video on explaining why. Peltiers are not made for air conditioning.
Thanks for your experience but ...
The experiment is incomplete:
1- The room you are in is not as hot as outside the house in the summer, which is approximately 30 ~ 35 ° C
2- The fan does not work during the experiment, and so the temperature logically drops below zero
3- The radiator and coolant cannot be exposed together. Because that the radiator gives a high temperature and the coolant gives a low temperature. But in this experience they are together !!!!! This means that the room temperature is very low and the experiment is unfounded
Upload your own experiment video then. :)
There is no pratical application for this to be used as an AC, pretty sure he made it to show others what temperatures he got with the configuration for their project using peltiers.
Exactly! I just wanted to show how the cooler performs with such a thermal load.
what kind of psu need this 12706 peltier to start ? and how must wire it ?? please help ,,,,,
Hi! Please check my "Peltier cooling in practice" video where I explain everything. I have a whole playlist dedicated for Peltier cooling. It contains everything from basic practical to advanced theoretical stuff.
pls.try to reverse the position of Peltier module your big fan is in coolside
Why?
Hi
This is bharat
Bro this is ready made kit
How much
And is it possible our cat
Hi! Please refer to the affiliate links in the description for prices.
Those radiator fans are not installed correctly.
Then what is the correct way?
@@CuriousScientist The fan should push air in to the radiator so just flip the fan around.
@@ss-sq1hn Would that significantly change the airflow? Because as far as I concerned, the direction of the airflow does not matter as long as it is maintained well. Cooling in this case is about transferring the heat between a warmer (radiator) and a colder (air moving through the lamellas) object. I can't see the direction in this. In this particular system, it doesn't matter, and I strongly believe that in general, pushing or pulling the air through the heatsink or radiator does not give any significant difference. If you can show me a system with proper numbers where there's a significant difference between these two, I am glad to reshape my ideas. I will also make a video about this in the near future.
I am not bullshitting. Those fans are designed to make air pressure. Not a vacuum. Higher pressure air to the radiator is better than weak vacuum ''flowing'' throught it. It will make difference. All you need to do is to test it. Be free.
i can show you the system i have.. How can i send you the pictures?
i feel like they charge too much for liquid cooling components...like they are such simple things...a tube? a cylinder that holds liquid??? this sht should be like 50 cents or something lmao
A radiator is typically made of aluminium or even better, copper. They are expensive, especially because they have to be formed, soldered...etc. The plastic parts however are really overpriced. I think it is because they are "specific parts". But you can find similar parts cheaper if you browse a little on Aliexpress.
wish people like this would do less talking and make these videos like 15 minutes. wasting my life watching these long videos. Yall have good ideas and great things to say but you go on and on and on lol
You can always speed up the video or skip parts of it. No one is forcing you to watch every second of it.
