- Homemade Peltier Refrigerator Air Cooler with thermostat! How to turn an ice chest into a fridge! no ice needed. easy DIY. super easy to make. full instructions in the video. unit cools fast and maintains set temperature range by use of a lighted LED thermostat. only 4 items needed: (all items bought on amazon). 1.) 5-quart cooler (coleman) 2.) 12v/6a peltier module, 3.) 12v thermostat and 4.) a 12v plug with cord. great for all kinds of uses and at only 6a(12v) or 72 watts, it easily runs thru a cars' 12v accessory or power port. want more storage? check out my previous video... "The 5 gallon bucket fridge".. link for that is posted below *along with the 4 links to the 4 products used in this video. wanna run either of them on house current? use a 12v ac/dc transformer as shown in the video. note that the 12v peltier module i used is rated to cool up to 10 liters - so it cools fast and holds in the cold temps. also note that the unit can be made without the thermostat but for only 5 dollars more it's definitely worth using. it will consistently monitor the internal temperature and will kick the unit on and off at any pre-set temps that you decide. if you like the project please rate, sub (click bell) and share...

Sweet find on those thermostats... man... gets me thinking more about just using for when I find runaway cooling free freezers or maybe some other temperature controlled devices to make for an easier repair. Nice design and work!
Pretty awesome, definitely a lot to be learned from your videos on how to do things in a less complicated way.
You are definitely doing a great service for your fellow man, thank you!
Can't believe I'm thinking of making one of these. It's -16 F outside right now and going to be -27 later in the week. A good inside project, I guess!
Nice work once again my dude! I have been planning on playing around with a peltier-based version of your DIY dehumidifer/AWG design and seeing if I can make it work, so I am excited to see this :) Thanks as always!
thanks ...and if you get it to work (or even if you can't) consider posting video on it or your experiments with it 🙂
Keep on Rocking my Friend! Awesome project thanks for sharing. Thumbs up video ~John
Once it starts warming up, I'm going to have to figure something out for my off grid cabin. Been living out of an ice chest for 7 months now.
ME TOO. 2 YEARS😅😅😅
Amazing little item..... I'm sure i could find a good use for it out here in Arizona
hi there and thanks, absolutely, cool drinks on a hot day 🙂🌞
I love your creativity and experimentation.
hi there and thanks 👍🙂
@@desertsun02 Yes your very ccreative. Im binge watching your uploads as I am looking to try out some of your work. Thanks for sharing.
I did this back in summer, but i even made the cool box from 50mm foam and ducktape as i needed a custom size...old cpu heatsinks etc, all was fine till i wired it into the van, the vans 12v has spikes from the solar charger about 3 times a second, scrambles the temp reading, works great when the sun goes down.....
how many peltier chips do you think it would take to cool down a 119 qt cooler to 34-36 F? Have an idea for a DIY meat dry ager. Although Im thinking about using cooling blocks for the hot sides connected to an oil cooler filled with distilled water and a radiator coolant additive, which will then be submerged in freezing cold ice water for extra benefit (maybe overkill). But the goal is to maintain 34-36 degrees F at all times while meat ages for a few weeks. Insulating mods might also be considered for the inside of the cooler to prevent warming too fast, to help with efficiency of the system (less need to turn on and run)
Thanks , very interesting.
put expanding foam inside the lid before you cut it then at peeling stick weatherstripping to the lid or cooler itself to make it more efficient
eureka moment with the cool boxes! (best things are always the simpliest)
I have a fan, Peltier device, two heat sinks.
cut hole in top, fit cold side heat sink inside, wire up to 300W solar panel, cold bear all day long
Very well done. I was searching for a peltier cooler conversion, and BAM deritis. ;) . I see the Amazon listing says 72w. I have never used the peltier devices before, but somehow I assumed they would draw less energy . Did you measure the actual current?
Good day to y😃u.
You and your ideas ARE A PREPPERS DREAM COME TRUE 👏👏👏👏👏👏👏👏👏👏
Thank you kindly
Awesome video sir! I'm just wondering if this could work on an 8-liter cooler.
I would turn the fan around. Basically, you're warming the lid.
Pulling the air through the radiator will also reduce dust buildup.
Might need top guides if the radiator gets warmer because of this.
Neat use of peltier though!
Thank you! Cool project. hee hee.
i wonder if we can combine this with your latest air cooler with the hayden radiator
Well done.
thanks 😎
Can this be paired with your radiator fan? Thanks in advance 🙏
Heyyy! I'm new at this kinda stuff. I was wondering how and if I could skip the plug and transformer you mention, and wire it to a USB plug. That way I could use a USB to USB cable to plug it into my USB plug in my car or USB plug in my house. Any help would be greatly appreciated. I'm just starting to Doordash, and this would be very useful. Thanks!
So before I buy, do you think this would work (well) to keep an ice chest cold for your radiator/fan cooler? I built one but struggled with the water warming up because of the heat from the punp and... ARIZONA... What do you think? I'm trying to get this set up before summer on solar. Thank you so much for your videos. You are the OG diy cool ❄ guy!
hi, this cooler is great for food and drinks but the radiator/fan air coolers i make would overpower it (meaning the ice-chest wouldn't keep up with the radiator/fan and the water would get warm.). those radiator/fan setups are great for cooling (and heating) air - but it would be an imbalance. those radiator/fan setups are very powerful so you need something stronger to keep the water cool. my best suggestion is to make a larger DIY evap cooler (i have one that i call the 'blue cube cooler'. those chill several gallons of water quickly (the water in the reservoir). you could use that water in the radiator/fan setup.
@@desertsun02 cool thanks for the reply. Don't like wasting $. I have nade a few of your evaporative coolers and they work well... I'll try the cube. I actually started building one then saw the radiator cooler.. Fun stuff! Thanks
I wonder if you can plug this to a jackery 500 and how long will it last
Is basically the same set up as the 100 watt solar heater but for cooling. How the heck did you figure out all these radiotrs and thermostat and cooler parts out. So epic. I'm gonna make both of these
hi. it's pretty simple. they sell the peltier modules already assembled. and the thermostats are sold on amazon. (you just have to assemble the optional case). the peltier modules are also sold on amazon. i recently saw one for only 18 dollars. the thermostats sell for about 5 dollars.
Hi, I’ve been watching your channel for quite some time now. And I just want to say THANKS FROM THE BOTTOM OF MY HEART. I need to ask you a question please answer if you can . Can a hobo stove be used indoors I need something that doesn’t require alcohol. Again thank you for helping us. Many blessings
hi there. thanks for being a viewer of the channel. it's much appreciated. if it burns wood then i would say you shouldn't use it indoors. a wood burning stove produces lots of smoke.
Omg you responded, thank you sooooo much your a celebrity to me
I just went a got the 4 cinder blocks and did that on my balcony very pleased with it, natural fuel from nature, cheap and easy over the years you have taught me soooo much and I have did many of these to get by you are truly amazing, I just can’t get my solar set up please help
Hey I was wondering if anyone could help me with the correct sizing of a color panel and battery needed to run something like this?
I had a heat for one like this. Do you know how to do that?
Great video! Could you use this as your ice/water source for your portable AC cooler?? I would think the ice would last a lot longer in this device?.Especially if you could get the temp down to freezing.
hi. sounds like a plan. it should definitely make the ice water last longer in my portable ac
@@desertsun02 does it push a ton of air ??? Because it be cool to put hole will pvc and make it a a/c unit
@Weirdo Wolf studio hi there. peltier cooling units don't push enough air to cool more than a small space. it could air condition a cat or dog house but that would be the limit
Hey Bud! I sa your water generator. If you take this cooler and put water in this and add a little pump, run the cool water thru a copper coil with a return to the cooler, I bet you could crank out some distilled water. How much electricity does the fan, thermostat and Peltier draw? And how do you wire the electronics? Just straight positive and negative?
You might have to run a couple peltires, I don't know. You could for out the details. I'm thinking solar panel and battery. You can buy a mini fridge for about $40 on amazon and do the same. 90 watts. Just need enough water to flow thru the copper. A small pump is like 5 watts. I am off grid poor old women. Hauling water jugs in is hard, IF I can get to town for water. I really need to generate my own drinking water. I have to drink dirty water when I run out, if I have any at all. Please help me out. I have a 100 watt solar panel which I know would not be enough. I am going to add to it. Like 4 more over time. The living is hard in places even on this country. Thank you.
Apologies for asking the following. My take is that this is a chiller and not a freezer? Can this idea be jacked up to keep meat frozen with camping for instance? Here in South Africa we go to a place in the wilds where temps often reach between 40 and 50 degrees Celcius in summer. Thanks a ton for the brilliant ideas.
hi. that's correct, this is a fridge (not a freezer). peltier technology can't freeze things (including water into ice) in any usable way. that's because it only drops the air temp in the fridge a certain amount (based on ambient temp). 36F drop is basically the max. drop.
@@desertsun02 Thanks friend. Appreciated.
Hey mate just a quick question, do you think something like this could practically work on a much larger chiller (around the 200L mark) given that you increase the number of Peltier modules proportionately? or would it use up too much energy.
The purpose of this is for keeping game meat cold in hot conditions, in areas so remote that you cant readily access ice or anything. the plan would be to run two rows of 5 modules on the top lid, and two rows of 2 on each end, so that the whole cooler would stay at an even temperature. would this be enough, or would a container that size be too large to be cooled efficiently.
@@nareshclark8916 Hey did you get an answer to this at all? I'm thinking the same thing as you
@@Albert-gv2px na mate I didn't, I have a rough design, just not sure of how efficient it would be. trying for a 200-300L one, i'm a hunter, so want to use it for keeping the meat cool in really hot conditions where you cant buy ice regularly.
@@nareshclark8916 good luck yeh I'm just thinking of a design as well see what happens
@@nareshclark8916 You ever get this working for a bigger cooler like you said?
Hi my friend how you been, tell me something. I just was trying to fix a Mini refrigerator with the peltiers with my own peltiers and I mounted a fan on the back but sucking the air away from the heat sink. Does it matter whether it faces? Blow it into the heat sink or pulling the hot air away from it. Which way the fan faces? Let me know thanks
hi. all of the preassembled units that i've ever bought have the fan (or fans) blowing directly at (or into) the hot heat sink. the fan on the cold side is the opposite. it blows the air away from the heat sink (i guess pulling the air through the heat sink is the best way to cool it down)
@@desertsun02 Okay thanks I will look into that
Ty ty TY
Hi. Am venturing into the electrical world. Know next to nothing but bought all the parts in your video. Question--what are the white wires coming off the thermostat that lead to the cigarette lighter adapter? Thank you!
hi. the white wire is just 22 gauge coated electrical wire that i had. i buy it in spools of 25 to 100 feet.
@@desertsun02 thanks. Am having fun with this.
How does the cooling system work,this is something new to me,how does it make cold air
hi. basically the way that these peltier chips work is that they pull (transfer) all the heat to one side of the peltier chip. it happens almost immediately. so you have one side that is very hot and one side where the heat is 'gone'. (lack of heat = cold). you use the heat sink on the hot side to pull the heat away from the chip (so the chip won't get ruined). then a fan cools the heat sink. on the cold side there is a smaller heat sink. that heat sink gets very cold because it's touching the cold side of the peltier. a smaller fan is attached to that heat sink and circulates air on, around and through it. (and that cools down the air). for a more in-depth explanation of thermoelectric cooling you might check wikipedia. here's a link en.wikipedia.org/wiki/Thermoelectric_cooling
Can one of these be hooked up to a regular plug for the outlet? Trying to make a reptile incubator
Is this an upgrade compared to cooler box's that come with cooler fan , I mean is this like an actual fridge cooler keep cold like fridge long term?
hi. i'm not sure that i understand the question. but, yep, this is an actual fridge (not an ice box). in general, fridges are one of two types, compressor-based ones and peltier powered ones. this video shows how to easily make a peltier powered one. you could absolutely use this for the long term.
@@desertsun02 thanks 👍
I did something similar and I can't get it to cool past 50 degrees Fahrenheit any advice appreciated. Wish I could include some pictures for you
hi. 50 degrees is great! just a few degrees higher than mine but still really cold. I'd say try extra insulation (that can be as simple as wrapping the ice chest with a heavy towel or blanket). it may be only getting to 50F because the ambient temp in the room is a little warmer. these things drop the temp based on room air temp so maybe that is a factor. (you can drop a link to a picture of it in the comment section if you want). i always like seeing the projects that people are building 👍
how about the humidity??
NIce, what about peltier fan for 2021, it is time to dump the ice.
hi. unfortunately peltier is not strong enough to make a room air cooler. it only cools very small spaces.
How much water do you think you can cool? I was thinking of keeping 6-8 cups of water about 60f or even colder if it would do constantly.
hi. yes, this unit should easily be able to do that. 👍🙂
@@desertsun02 awesome, appreciate your input, and enjoy the videos even if its not always something I can do
Maybe I missed it somewhere, but you were showing the ambient temperature, and the heat sink temperature, but I don't see anywhere where you showed the internal temperature of the cooler? I would like to build something similar, but I'm curious what your internal temperature worked out to be? I'm looking to use it as an actual cooler for beverages, and curious if it will actually cool enough???
hi there. you must have missed it, because a big part of the video shows the internal temps. the peltier unit i used is sized to match the square footage of the cooler for max. cooling. the unit reaches comparable temps to a regular compressor based fridge. it cools food and beverages in about the same time too. (all three peltier fridge build (videos) that i've done are built with modules that can cool the space of the container. (they sell them with square footage ratings) so i matched the peltier 'module' with an appropriate size container. it's quite a bit tougher to figure out how to size them if you make it all from scratch.
@@desertsun02 I'm looking to build a small drawer fridge for my boat. I'm looking at a 3 chip 210w Peltier module. The drawer will be heavily insulated. I'm new to all this. Do you think that will cool below 40°F? It will hold approximately 60 12oz cans.
this would make my C3 cooler a real bad ass at the local beach....if it would work off 3 lipo4 12 volt 15 amp hr batteries..lol thats MY c3 cooler now.. lol
💜💜💜
Does it freeze up? Drip water like condensate inside the fridge?
it won't generally get to the freezing point (but close). if it does, it still works great though. condensate can form on the cool heat sink but it's minor.
Is there a way to use a Raspberry Pi instead?
have you performed any computational simulation for this?
hi. no, i didn't need to get that fancy. just used a module that is sized to the ice-chest. cools the air and food/drink down fast. (works about as fast as a regular fridge)
@@desertsun02 good job.. a very informative video.. cheers! :)

For more efficiency put 2 units in parallel for more cooling,but at only 6 amps draw!! Changing the exterior heat sink to a more efficient one will amost double the heat extraction!!
These peltier units are more efficient at lower voltages, but I don't think running them in parallel will lower voltage. If that were true, running 3 amplifiers off of a distribution block would be at ~5 volts instead of ~14 in my truck.
True about upgrading the hot side though.... but I bet replacing the single fan with a pair would be sufficient to see serious gains without taking the whole thing apart to swap heat sinks; It was only 20 degrees above ambient so not *too* much delta to work with. I'd also throw some foam in the hallow lid... an air pocket is a pretty good insulator, but it has been compromised by cutting a hole in it. Even the packing peanuts these components were shipped in would be better than nothing.
@@ur_quainmaster7901 I have an "Icebox",(used a 10# block of ice to keep things cold),from a 1969 Shasta pull behind camper that I put two units on the back of it tied in parallel with radiator style heat sinks,(plus I changed out the larger fans to higher "CFM" units,server fans of the same size) and a 2 step controller,(turns both fans on and peltier [TC12708 units],then once the preset temp is hit the peltier fan and peltier unit are shut down and the large fans on the exterior run for 2 1/2 more minutes. In doing this it prevents heat migration from the large radiator style heatsink from going towards the interior of the "Icebox".
Running them in parallel doesn't lower or affect the voltage,but instead the units share the amperage.
Example: you have a solar cell running a LED,(solar yard light,cheap $1.50 one), and it will have a specific lumen output,but you put 2 of the same LEDs in parallel and they seem to have the exact same lumen output,in reality the lumen output is only slightly diminished because they are sharing the same amperage. I'm not very good in explaining the effect.
I did upgrade the exterior insulation of the "Icebox" from a 1" spray foam sleeve to a 2" styrofoam enclosure on all 4 sides including the back of the unit,but at the point of the peltier units I cut the openings larger than the rear heat sink by 2" all around and at a 45° angle for good air flow.
All testing as follows was done with an ambient temp of 75° F.
During the startup the amperage is 5.87 amps with a voltage of +9,as the temp lowers to the preset of 36° F I see a drop in amperage used down to 3.71. The venting on the camper is a hallow section of the wall,(insulated), from the bottom of the camper,(coolest point,instead of a side wall vent 3 foot off the ground), and a rooftop exhaust point. Unit cycling time is once per 48.3 minutes unless the door is opened to obtain something cold. Recovery time is minimal at 7.4 minutes.
I tried using just one unit but the lowest temperature achieved and maintained was 42.6° F which was the same result as using a 10# block of ice for cooling and the peltier unit running time was significantly increased.
Hoping my set up will help you with your portable cooler?
@@steveseifertsr.8120 any chance you make a video of yours?
@@ChrisOh I would,but I would have to disassemble the cabinetry of my pull behind camper to show what and how it is all arranged...It can be done with a camping cooler easily tho'...just follow how I connected everything and buy the temp controller from Banggood.com...
Series is better, 6v instead of 12 increase their efficiency.
How long does it take to reach 10c internal?
hi. it's pretty quick. no longer than an actual fridge takes to cool down. a lot will depend on how well insulated the container is.
👏👏👏👏👏
Hope I’m not becoming a bother but if you ever get a little spare time can you maybe do a video on how to put together a solar system in a box I looked at 30 videos in a matter of a few days all so complicated, you explain things in a way that we can understand. Maybe one day, I don’t know how to store my little system. And I would like to be able to move quickly with it for hurricane season
hi there. check this out... it may help you. it's my video on how to set up a 'smaller' solar system. it makes it super easy to do - and runs all kinds of things for hours. it's not a lightweight system but it gives a super simple explanation of how to hook it all up. i'll consider making a video on how to put together an even smaller 'micro' system, but that will have to be in the future. here's the link to my video on setting up a system. th-cam.com/video/cgEvCLJuBkg/w-d-xo.html and here's a link to my video showing lots of things that it can run. th-cam.com/video/8LAjx_XAR90/w-d-xo.html
Thanks I’ll watch it again and go step by step I know exactly which one your speaking about I binge watch your videos from time to time over the years to keep skills fresh in my mind for emergency because none of my family members are into it one last question me.dessert sun is it true that I have to use a pure sine wave inverter I got a cheap 400 watt inverter, a 12v 9ah battery and a $10 12v charge controller no pure sine wave
And for the output wire from the charge controller to the battery may I use like alligator clamps on one side with straight wire on other side into charge controller and aligator chips on battery yes
My battery comes in today from Amazon I’m so excited to be building it today I been wanting to do this for years
hi. i'm not sure what you are running but for most things you do not need a pure sinewave inverter. many (if not most) of the non sinewave inverters that are sold produce what is called a modified sine wave.
What’s the wattage needed for the system to work?
hi. this particular one is 12v 6a so about 72 watts
@@desertsun02 ok thx
so this fridge is using less than 20 watts?
hi. it's a 12v 6amp unit so about (72w)
Hey dessert sun please help me out with my solar question whenever you can i value and need some help on building your mini solar system
hi there. regarding the one question. don't cut off the plug on your battery charger. you'll need to buy a charge controller if you want to hook your solar panel to a battery. 🙂
Ok, I’ll order one from Amazon right now, I don’t have a lot of money I saw one for $10 it’s 12v I believe I hope it works, I will continue to pray for you and your family, you are truly changing peoples lives sir, I’m bone and raised in the city I knew absolutely nothing about being able to survive without the regular basics, you taught me sooo much I made your gravel rock and activated charcoal water filter I did several of the food can indoor cookers I learned that alcohol can be used sadly for fuel and I don’t care who thinks that I should have known these things I did not, keep these videos coming and we who love you and your content will continue to support you ,with love.

Hello Sir, where to buy a real Peltier cooler ? i bought some from China and it's not cooling !
hi. i just get them on amazon. they've always have worked good (so far).
@@desertsun02 Thanks for your info ; i will order some , very soon, from AMAZON ; I'm Yaounde Cameroon
@@desertsun02 what is the cooling time for this model ?
hi. it's fast. several experiments shown in video. it cools in minutes
Hey i made one of those ice coolers and it works great but my problem is that our fridge is not big enough to make the huge ice block in your video any ideas?
oh and it was this one here th-cam.com/video/ITtlxjvLQis/w-d-xo.html
hi there. one idea is you could freeze the blocks in smaller containers and make several of them. if you want full size blocks you could buy a stand-alone chest freezer. those are only about $150 where i live. even the small ones (3.5 cu ft. ones) have plenty of room for big blocks and they are a lot cheaper than buying a new fridge (those are $600 minimum). if you don't want to buy the freezer then you can always buy the ice blocks (grocery stores and gas stations usually have them. only other thing i can think of is if a neighbor will let you "borrow" their freezer space
@@desertsun02 ok i will try the small blocks and thx for the reply
