- Unique DIY AC Air Cooler! Homemade AC! Produces very cold air with NO added humidity! (it's a closed loop system). and has an "air conditioning like' feel. very easy to make. is made with an all-aluminum heat exchanger (called a transmission cooler), also some 3/8" ID clear vinyl tubing, and a small water pump (12v 4.8w one used). essentially the unit just circulates cold water through the piping (which transfers the 'cold' to the fins). the room air is then circulated through the fins by the use of a small AC or DC powered desk fan) it pulls (or pushes) the hot room air through the fins and it cools down. the fins themselves literally cool down in seconds (about 20 seconds and they're freezing). for the tests i just used one gallon of cold water (from fridge) and one or two 'ice-packs' and i was able to get cold air for 1 to 2 hours. "if you use a medium size ice chest and a couple of frozen gallon jugs or ice blocks you should be able to triple the cooling time! (or for maximum cooling freeze the entire 2 gallon bucket with water, then when ready to use it just add a little water to the top *maybe 16 oz. (just enough to cover the pump) and set the pump into the water and you're set for a long time. main product used is an all-aluminum heat exchanger. you can get them on amazon. they've got several sizes and shapes. the particular type and brand i used has the best fin spacing for a small table fan. (it also has thick fins on it so they don't bend easily). cost 24 dollars. note that it is very lightweight (weighs less than a pound) and also has a small profile. the system could be used even in very tight spaces. and if you use a 12v DC fan (10w) and a 12v DC pump (i used a 4.8 watt one) you only need about 15 watts to run it. you could easy hook it straight to a 12v solar panel (or a 12v battery) and your set. and since it only pulls about an amp you could run it for a very long time on a single 12v deep cycle battery. give it a try! it works great! if you like the video please rate, subscribe, comment and share it around 🙂

thanks brother! 👍👈... it's one of my best for sure. i can't believe how long the cool is lasting. it's like the perfect heat exchanger for DIY cooling and i finally found it. (i've got 4 other projects with these already in my head) 🙂
@@desertsun02 can make a solar power ice maker vid perhaps.
@midway inn already done.🙂... if interested, here's a link to one

Kickass Genius!
now go get a mini fridge or better yet a small freezer. place that same bucket or bigger bucket of water inside said freezer drill holes in the lid run the tubes through it and have continuous cold water. Add alcohol to the water so it wont freeze up
Thanks for working this out, Glad to see you posting again!
It goes without saying - excellent idea! Keem ‘em coming. Love your videos.
Wow that is incredible!!! When I finally get some time I for sure want to attempt that. Thanks so much for the great videos
Good plan. Several decades ago my job was to braze up those trans coolers. Best
Great job! looks great, really straight forward and all the parts used shown clearly. very well done.
This is the coolest thing i ve seen the llast years ,
Pretty slick! I can't believe that I'm watching a homebrew air conditioning video while it's 15 degrees outside, but here I am. I spend a lot of time in a tiny off grid cabin, and I'll be building one of these. Great inspiration. Thanks.
That is great idea. I'd add an insulated ice chest to the mix and put pvc with copper tubing coiled around it in ice chest and run water through that first and then to radiator . I get the copper coil idea from the copper coil ice chest cooler from youtube.
It might be overkill but it might keep water cooler for longer period
I see a Million subs in your future. Simply wow. You just solved RV and Van dwellers cooling riddle. Amazing, Thank you. May I suggest, title includes heat exchanger cooling. This video will get ton more views. People need this, you will get traffic.
honestly, i've tried using that term but it doesn't seem to generate the views on other project vids. (the main thing is everyone sharing, liking, commenting, then sharing again - and all of that). got to get the youtube algorithm to kick in and blast it into the stratosphere. i agree that this could help lots of folks in lots of situations.
You are a genius.
The bucket and the plastic tubes could be insulated.
thinking the same thing. also water could be put in a cooler. wonder how cold it would blow then. and if the icy water would cool longer.
Good idea! Add Styrofoam or put it inside a picnic cooler
Actually you don't need the insulate the water chest or the hoses you got to remember you're trying to cool the whole room if the hoses and chest are in the same room they add to the cooling effect do the math
Perfect DIY video. Purposed! Planned! Parts! Demonstrated! Not 20 minutes of talking! Ty sooooo much! Just ordered the radiator!!!!
hi there and thanks. it's great that you're building it! (it's one of the best air coolers i've made)
I ordered all the parts I needed off of eBay. Very anxious to try it out. Thanks for making it so simple. Have a good day
hi. thanks and you're welcome. good to know that ebay sells the stuff. i always forget about that site for some reason
@@desertsun02 eBay is my number one choice for everything
@@desertsun02will any aquarium work?
You want to put the coil in a shroud/box opening that just fits the coil fins. Then you want to fit the fan to it’s own hole in the box blowing out of the box. This will put a slight Vacuum on the box which will pull air thru the entire surface of the coil. This will improve the heat transfer into the coil significantly resulting in even cooler air output. Not a high volume unit, but good to take the edge off. I built a similar larger system using a car radiator and circulated 55 degree irrigation water thru it on it’s way to the sprinklers. It definitely took the edge off of the hottest days for a smaller area…
Looks like you're on the right track thank you for the value of your time I was thoroughly entertained and I'm ready to take apart an old air condition to get the parts and I have an old television with the fans.
thank you for a great 💡 idea.
keep up the good work.
Fantastic a/c system. I'm designing a two person predal assist electric mobile unit for camping and your design is a perfect solution. The fact that it uses very little power to keep two people cool is fantastic. As for a free heating source I will be using an evacuated vacuum tube solar heating system made by SunSank with a 40 gallon tank capacity. Free hot water from the sun. Thanks for sharing your A/C system. 👍🏻👍🏻
YOUR IDEA IS EXCELENT BUT I CAN HELP YOU BY USING VACUME SOLAR WATER HEAT CLOSE LOOP AND PRESSURIZED SOLAR WATER HEATER AND YOU CAN USE DC SOLAR WATER HEATER
Im building one for camping too. I used a pc radiator and an usb water pump (5v 2a)ordered on amazon. Both should be able to run for 5hours minimum. All is rechargeable. Since you need a bulk amount of ice i figured a portable dc freezer would be needed for continuous ice supply for extended camp trips.
man dude youre the best

Another great video I've seen of yours! I think I might make a copy of this one. I think some insulation of any sort on or in the bucket or hose would be a great addition. Could you share the amazon link for the radiator? I like the idea of being able to use hot water as well. How hot do you think a normal pump/hose could handle?
That's so awesome. Thank you.
very welcome! - thanks for commenting 🙂👍
In florida if you drill a well 300' deep and put a circular coil down it up to a heat exchanger and a fan you have a/c . Water 300' down is usualy 30° cooler than your air temperature. Ice water in a bucket well you are essentialy using your freezer as a a/c .
Consider a makeshift fan shroud too, to move the air across the majority of the cooler surface, especially with the smaller fans.
I've watched several of your builds, enjoyed your channel for quite some time now. going to build one one of these days.
I just designed one that I can use in my skidsteer. With how hot it's been A/C is a must in the summer when running equipment. I'm going to install it tomorrow the first time. I am looking forward to what the results will be. My skidloader is enclosed cab however I've used it all summer without the door because it's way to hot with it on. If this ac cooling system works door can stay on all year!
Gump you are a damn genius! Thank you for uploading this project.
hi and thank you!
This is exactly what I was thinking with the addition of a 12v fridge/freezer.
And where would the heat from the fridge go?🤔
I made this ac after watching your video... I freakin love it!
that's great! 👍👍👍
NIfty! Would one of those little pumps be able to keep a counter-top ice-maker running too? I think I remember you running one of those off a Harbor Freight system years ago. I'm betting a pretty decent self sustaining system could be made now with solar panels getting so cheap (relatively). You'd just have to compensate for evaporation I think.
Thanks for the great idea!
You bet!
I was wondering. You have a fan in front with the grid behind blowing forward and a fan behind the grid blowing through. Did you notice any differences?
Awesome video!
Thank you! 🤠
yes i did. it was a couple degrees cooler when the fan was behind but the air moved a little slower (it's a trade off). since it's cold either way, i go for the fan in front. lots more air and still really cold.
Thank you, utube has videos on building your own
Pumps
I have a question about the the speed of the water flow.
I'm thinking of building one of your designs here but with 1/4 inch drip irrigation line. Do you think that will be an efficient setup? I have a small heat exchanger out of a window AC unit 5k BTU. You having years of experience and knowledge building these I'd like to know what you think? Thanks in advance!
Looks good, how about using a picnic box ice cooler. The insulation would keep the water cold for considerably longer.
Awesome 👍👍👍
I just checked on Amazon and this Hayden Automotive 403 Ultra-Cool Tube and Fin Transmission Cooler became 1#best seller. Think its cause of you :P
Dang it! TH-cam constantly has me have my husband doing projects! Haha
sounds good to me! ✔🙂
I was watching your ice maker video and was thinking about building an AC unit like this but that uses the ice maker’s hardware to keep the water cool - or you could just have it tilted to dump ice in a cooler every 15-30 mins or so - feeding the water line from the system radiator back to it. That kind of system could probably run on less than 200 watts - except for when the ice maker power usage spikes when it starts up.
Anyway to avoid using icepacks? I appreciate your video I am just wondering if anyone came up with an idea to cool the water itself
Great idea. Built one using a 48 qt coleman extreme cooler. Drops temp from 91 to 67 by cooler in a few minutes. Only issue I have in Florida is the amount of condensation on the fins from the humidity, if I want to se this in the tent, I'll need to rig a tray and pads to absorb the water. Getting ready to make the cooling tower for the pool patio, which is where I use this unit.
sounds great - and awesome temp drop from 91 to 67!
Could the fins and entire unit not sit on top of a grid on top of the bucket of water thereby letting the condensation run back down into the water bucket?
The name of the fan in the thumbnail
Make a little water trough that goes right back into the water
Question : do you have recommendations on beginners guide to solar books.
Excellent.
Super idea
REALLY LIKE YOUR IDEAS AND PROJECTS....I WONDER IF THERE'S A WAY OF INCORPORATING DRY ICE TO FURTHER MAXIMIZE THE COLD TEMPS AND COOLING TIME? GREAT VIDEO THANX FOR SHARING
It'd be great for if your outdoors in a tent and you have a spring cold water running you can cool your tent down
You are the only person on the Internet who explained the geo thermal cooling.Please can you make one with the underground cooling without the ice method for home cooling?Thanks
I put it together. It works. Great idea.
6 ft. away and could feel the cold. We're putting it on the o-turn mower.
I live in Fl. Hot and humid. 92° today.
Air-conditioned lawn mower. What will we think of next.lol God bless & thank you for your wonderful idea.
sweet! sound good 👍
YOU ROCK‼️‼️‼️‼️🙌🏾🙌🏾🙌🏾🙌🏾🙌🏾
thanks ✔🙂
I have thought about doing this . But i wanted to do a sealed system under the house . My idea was to run the hose threw the floor to another radiator. That radiator would be in a pan of water or antifreeze and then cover the pan with dirt . You could get the cooling in the summer and warmth in the winter . Check the temps under your home it is alot cooler under there .
Im only half way threw the video so I don't know if you have a pump in the bucket to pump the water up or not but if you put a reservoir above the radiator it should gravity-feed because the hot water should rise allowing the cold water to settle at the bottom where your radiator already is
Best one on the internet for DIYers! Peltier modules are inefficient, good ol' ice is the best. How long could it run on $1 bag of ice from dollar tree in hot room?👍
I just built this last week. Same transmission cooler. I used a fountain pump, cooler, and a ryobi 18v fan. It works surprisingly well. I am planning to use it when car camping on an overland trip next week!
sweet!
Dude, nice job! Just to springboard off this idea;
I’m thinking closed loop system with like 25’ of this line coiled up in your freezer and everything else the same. You could use a small 3/4” hole saw plumb it up and make it look Frankenstein :-) right into the freezer
This could be way more efficient than a portable AC as far energy is concerned
how about connecting both hoses to the pump with a small coil of hose in the water for a closed system, it may keep the water colder longer, using a salt brine would also help
Great job
Will the salt decrease evaporation rate?
@@aliksashka not the original commenter but saltwater has a lower freezing point, if it's salty enough you could potentially have sub 32°F liquid water from the freezer. It's specific heat capacity is also(slightly) higher, due to the properties of the dissolved salt. However, if there are any metal components in contact with the saltwater, you open yourself up to significantly higher corrosion rate, and if there are dissimilar metals in contact, galvanic corrosion(sometimes referred to as electrolytic corrosion). All in all, unless you NEED the extra degree of cooling or you know 100% your components are all one type of corrosion resistant metal or plastic, I'd choose longevity of equipment and thus fresh water.
Edit: evaporation isn't much of a concern with this design, as it'll lose effectiveness before the water heats up to the point it would rapidly evaporate. The intercooler or whatever he used won't allow for evaporation, it's designed for closed-loop operation, vented at the reservoir, exactly as the build is designed.
Edit 2: @Doc Inc, a closed loop that is expected to go through thermal transients (temperature changes) that has so surge volume (space to expand and contract) would over pressurize. It would likely fail at the hose connections(any of them, I'm not sure which would be most likely.) You'd need to add a very low pressure relief or punch a pin-drop leak into the discharge, which may effect efficiency. Either that or install an accumulator/vented expansion tank on the suction line, and the latter of those options kind of defeats the purpose of a closed loop. I suppose a small plastic check valve, again on the suction, might do the trick. It'd be cheaper than any of the other options.
@@USNJackman Thank you very much for this detailed explanation!
@@aliksashka no problem at all! I've taken classes on heat transfer and fluid flow, as well as design materials and water chemistry. I love to share the knowledge I have and learn more! : )
I like to hoard/yard materials and things I can use that I find for free, penny-cheap, or from dumpsters. Last summer I made a few small AC units using milk crates lined with garbage bags, 12v computer fans mounted on both sides, and then I filled up the crates with tall bottles filled with water that I froze. I froze enough that I could keep them circulating. I’m looking to make something like yours in this video. A few weeks ago I found a box of about 30 cryo frozen packs, brand new, unused, and I’ve had this large cooler I found a few years ago, but I’m going to cut holes in both ends, use aquarium sealant and attach these push button drain thingys that I saved from liquid laundry jugs on the outside of both ends, attach 2 plastic Gatorade bottle tops with the lids for inside incase the push button thingys fail, then fill it up with the cryopaks. So I can keep frozen stuff cold after I get groceries. I want to add a hot or cold water circulation function with something like in this video using the pumps from a submersible aquarium filter, and the heating element and tubing I found that works from a coffee maker that was sitting Outside next to my apartment dumpster. Maybe even add some LEDs or something. I’d like to add a cut off function for when certain temps are reached but I’m not that knowledgeable about doing that and only basic stuff. I do have an AC unit that works but when my apartment took the old baseboard heaters out which had a special outlet for it, and replaced them with energy efficient ones, I have no way of powering it up: I tried making an extension cord/adaptor with parts and heavy cable from Home Depot and an electrical supply store to be able to plug it in where I plug the range in and it only turned on and not the motor for the fan. It’s a $700 AC unit which cools my 2 bedroom apartment fast so I’m kind of at a cross roads now. Not sure if I should make an AC unit, buy one from Home Depot for about $200 or make 1 more attempt at getting my AC unit I have working. I’m not an electrician but I do know that the AC unit runs on a 230-250amp and not a 110/120amp. So yeah…
Good idea. Although a system that pushes air across the entirety of the fins would be much more efficient.
I did that when I was a kid used to garden hose water the plants
Genius!
I like this closed system (with closed bucket :) ). Have you try the different if using double unit (fan&radiator)? I mean one unit for cooling ordinary water and 2nd unit for blowing the cold air. Both unit is connected? If it works it mean no need ice block water who cost electric. Keep cool work..cheers.
so ive been testing various solutions for my van in the Phx AZ heat... now that humidity is higher i really want this to work..but last night i tried 2 1 gallon frozen bottles in cooler and they were almost melted in few hrs.. i went ahead and bought 4 more 1 gallons jugs of water and they are freezing now... i have a feeling to get a solid 6-8 hrs of sleep in 100 deg+ heat you'll need 6 of frozen 1 gallon bottles...
How much did all this cost you? I wonder how well itd work if the find were submerged in cold water and air went through the tube?
Hi, I been a fan (pardon the pun) for a long time. Has you ever though of combining this unit with your evap air cooler to get the temp down further?
hi. yes you could do that. i've got a video on just that. (with a larger heat exchanger). it makes what is called Indirect evap cooling (no humidity)
I love your channel. I would make one suggestion. You should add links to the products in the description box. You might be able to get some advertising dollars from them.
I wonder if you use dry ice how much colder you could get the air?
An automotive air conditioner condenser would work too- it’s big enough for multiple fans -might cool a room faster
Good job
Thanks
Another awesome video. Does this build work to lower the ambient temperature of the room? I’m considering building one myself in the next few weeks to ideally save on AC costs.
hi there and thanks. yep, it certainly does. during testing i had a thermometer laying out on computer desk (to the side of the unit about 10 feet away) and near the end of the test it was 7 degrees lower. *this was an un-planned event (and not officially verified) so i didn't include it in the video). i did film it though (along with my surprise) so i'll post that along with other experiments in a future video. note: it works so well i've already ordered 2 more 'small radiators' (of different sizes and shapes) along with extra pumps, fans and tubing so i can make a couple more projects.
save on AC cost? how do you plan to cool your water in your setup? :)
Hell it could double as a heater as well if you got one of them heating elements that claim you just set it in a coffee cup and just stick it in the bucket
Many thanks!!! Would this work in a HOT and HUMID environment???
hi. it sure would. my first day of testing it was 70% humidity here (very rare for desert) and it was cranking out the cold air. (i'll be posting some of the earlier tests in a second video)
If you run the fan on a slower speed, the air stays in the cooler a bit longer and you'll get lower output temps.
I suggest converting an aircooler with this kind of setup. As my place humidity is 65% this will do great.
hi. i've got a video on that coming up soon 👍
This is a little bit closer to what I imagine a cheaper geothermal system could be. I want to try to make one that goes ten feet into the ground to get heat exchange without getting cold water to do it.
I'm telling ya, as soon as I getting my tiled installed, I'm going to try some of your experiments. Thanks!
please do! - this one (and 'spin-offs') of it will probably be my top summer time air cooler projects. i've already got 4 more project ideas (floating around in my head) of how i can use these type of heat exchangers (now i just need to buy a few more different sizes and start building)
add a peltier complete unit and you can prolong the low/cold temperature, providing you can dissipate the heat from the peltier. Maybe to use it to boil some water?
niceeee yea thats the one i like alot as it fits a larger fan better :) quick questions.. 1. in your experience how does pump speed effect duration and cooling? 2. what about fan speeds? have you played with increasing decreasing fan, pump and/or adding additional insulation around the fan?
hi. i've only used a single speed pump so i'm not sure how a different pump speed would affect it. regarding the fans, as you run them slower the air temp will feel cooler (more time in contact with the cold fins). then again, if you are sitting right in front of it you'll have more of a wind chill effect if the fan is running faster.
Wow. This is great! I have never made anything before but I am going to try to make this. I have been trying to figure out what can cool and heat off grid. It would be amazing if this were the answer! I could also get a Bourgerv fridge/freezer and made ice in it (low watts) to freeze ice. Or an ice make. Thanks for this fantastic idea!
hi there and thanks. yep, these little units are pretty cool (or hot). i've been using it everyday since i made it.
@@desertsun02 How much do you charge to build one?
Desertsun, do you get strong air when you put the condenser in front of the fan? Do the fins restrict the airflow? I can't put it at the back because the back of my fan is not flat. In humid location, the condensation will cause humdity, will it be as much as the evaporative air cooler?
hi. it works good either in front of or in back of a fan. the fins only restrict the airflow a little bit. note that the condensation doesn't create humidity it actually reduces (removes) humidity (by pulling the water out of the air). 😎
Are these pumps the same as a Fish tank?. Also for heat you could use a fish tank heater . Cool
hi. fish tank pumps usually pump air - but some people use water pumps in their tanks too. fish tank heater sounds like a good idea. i never thought of that.
@@desertsun02 thank you for the information
sure thing 🙂
Would your 80 watt fan you've used in other builds make this ac work better or would that be overkill? What size room might this ac keep cool? What might the temp drop average be in a 9 ft by 12 ft room if it was 105 degrees outside in New Mexico? Thanks desertsun02. Love all your builds :)
hi. that might be overkill. the 80 watt fans probably pair up better with those thicker heat exchangers i have used in previous videos . many factors go into the temp drop - but there should be a significant drop
Do you think a usb powered fan has enough power to blow on a wet sheet to cool a room?
hi there. a usb fan and a sheet would give you some cooling (in a dryer climate) but it would probably just give you 'personal space coolng'
I didn't have much luck with the liquid nails and wooden dowels, would you happen to have any other suggestions on keeping this thing upright? I was looking around to see if I could find an upright and stable metal rack I could lash it to with zip ties. Alternatively, would strapping it to a larger fan similar to the ones you've used for the copper tubing fan work?
hi. well when i did very early experiments i just used a standard brick or two. kinda heavy but works. or there are all sorts of things you could zip tie it too. i'm working on a styrofoam stand. i'd give the dowel idea another try. it worked perfect for me.
@@desertsun02 I think I got the wrong type of liquid nails then, I went ahead and zip tied it to my large fan the other night, once I get my new pump and get everything running I'll have to give you an update on how it's working.
Thanks for making all these cool builds by the way, I had built your ice chest and fan cooler years ago, which has helped me in the past, though I think the fan I stuck in there isn't strong enough to push out a good cold breeze, I'm optimistic about this transmission cooler build.
Edit: Got the pump and everything set up, the cooler has done well in making my apartment a little more comfortable, got the cold water in an ice chest and I've been piping it through with no problem, thanks again for this build idea, I can manage the summer heat with this thing. Since then I've taken it off the big fan and made a crude box out of an old small styrofoam cooler I had laying around, later on I'll be taking a blower fan I have and force air through it on one side.
@@desertsun02 Hi again, I just wanted to say that you're a genius, after trapping the cooler in a crude styrofoam shell, getting some proper block ice and sticking a blower fan behind it, I'm getting some honest to God AC air pumping out of this beast. Though seeing as this isn't an evaporative cooler, do you think the windows should be shut or partially open for this little machine?
Sorry if I'm troubling you like this, but I figure bringing this up to you would be the best call, you have a lot of experience in these DIY air coolers.
hi. you can just keep the windows shut (if you want to). this type of cooling does not need to be vented
what effect would the size of the fan create as far has area cooling and longevity before replenishing the ice packs,Thanks
hi. a bigger faster fan can cool faster but will heat up the tubes faster (it's kind of a trade off)
Cool !!
If we were off grid and using this setup for cooling and using solar power would you recommend using a small ice machine ice to chill the water or a 12v fridge and swapping out ice packs? I’d like to know your thoughts on which system may be more efficient or convenient if the grid was down. Thanks for sharing your DIY goodness!
hi. i've thought about using ice machine or small fridge too. my ice machine cools off water very fast but i'm not sure if it would keep up or not. it might but i haven't tried it yet. swapping out ice packs is certainly an option too. some people freeze gallon jugs of water and use those. the bigger the ice blocks the better.
@@desertsun02 I think the small fridge and ice packs would hold up better with the fridge in hot weather. I think if the room was hot the ice machine might struggle more. The idea would be to have enough cooling to be able to produce cool air around the clock by swapping out packs or frozen water jugs from the freezer. I’ve seen online it takes about 3-4 hours to freeze things. If the system uses an insulated reservoir we might be able to pull it off as long as the freezer could hold enough volume to always have something frozen.
I wonder if i could use this idea for a ground water loop in my furnace cold air line to cool my house... maybe free ac with a couple holes dug
hi. it's a good idea. bury the right amount of pipe at the right depth and you can generate 'nearly free' cold air.
This is pretty neat man. Have you considered making it a closed loop system with two radiators with a pump in between? If you added a salt/antifreeze to the loop it would allow it to reach sub zero temps. You would not gain any size and only the weight of the seconds trans cooler. Mount the exterior trans cooler to the top of say an igloo cooler with the fan pushing through the radiator. Also mount the pump to the top. For kicks you could make it all 12v and make it portable by power with 18650 battery packs. You could then either make the battery pack detachable or make it a built in package with an onboard charging board that uses USB-C to charge and/or power the unit indoors. Just some ideas. I still think this build by itself is fantastic. Do not take my "ideas" as anything other than inspiration by your awesome work .
Mr. Munkeymeat you should make one and post a video.
If the temp was below freezing then wouldn’t it would freeze?
what if one radiator is kept in flowing water, would it be feasible for cooling. (ambient water temp is 24°C)
Umm.. I'm late but. Salt will destroy an aluminum radiator.
It’s the most efficient way of cooling
very true (one of the best for sure) ~ costs almost nothing to run these things and they generate 'tons' of cold air
Great video, did you get the little radiator on Amazon?
hi. yes i did, but you can find them on ebay too along with many places that sell auto parts 🙂
I made a similar version of this except I used a cooler and the tubes come thru holes in the top so the Ice is inside the closed cooler. It works well the only problem is 4 whole bags of ice melts in 15 minutes! How can I make it last longer?
hi. couple of things. slow the fan down some. the slower the fan runs the longer the ice lasts (that can add hours). another thing is to use larger blocks of ice. ice cubes will melt 10 times faster than a large single block. i usually use gallon jugs. you can also use those 3 gallon plastic tubs. they make a 25 lb. block that can last many hours. they sell those containers for 2 bucks at walmart
Try switching the tubes so it pushes the water up thru.
where does the condensed liquid goes which appears on coils/fins due to circulation of cold water.?? does this cooler add humidity to closed space/room or we have to provide proper ventilation.? please guide..!!
hi. i don't have condensation issue where i live (not very often that is). it sometimes will bead up but not enough to drip off. since it's a closed loop the unit doesn't add any humidity to the room. (and when the water beads up it's actually removing water (humidity) from the air.) no ventilation of any kind is needed with a system like this. it runs perfect in an enclosed space 🙂
I got house boat. I could use river water. Because it’s usually cooler than air
perfect idea. i've talked to other commenters who use my (similar but larger) 'copper pipe heat exchanger' air cooling units just that way. specifically a sailboat and lake water (but the same idea)
You will need a larger pump. i just bought a pump from harbor freight. $11.00 it only has a 3.5 head lift. mine is going in a cooler. 3 feet is plenty for that. your looking at 8ft or more
What would you say worked better - having the fan on the front (extraction) or at the rear - blowing over the fins?
hi there. i like having it on the front. blows more air that way.
@@desertsun02 just looking for the parts to get it sorted tomorrow.
hello! this is awesome thank you so much. could you share the links for the items? maybe if you do affiliate or something with amazon you can make some money from the links when we click to buy. ALSO, do you think this would be safe to run in a van? (40 sq. ft.) THANK YOU!!!
hi and thanks! i think it would work great (even awesome in a van). i didn't post exact link for trans cooler because i didn't want to give all the business to just one company (plus sometimes the price gets raised by 30% or more right after i post a link to some things - presumably due to the increased interest). best way to find them is to just search for transmission coolers. there are a lot out there.
Hello there, DesertSun02. As luck would have it, I have a sizable intercooler that never made it into my car before I killed it through negligence, so I have or can acquire everything on the materials list... Except I don't know what type of pump to get. Without being too specific(I've seen your reasoning behind not giving out links for specific items), could you give me some criteria to look for and perhaps where I should or shouldn't look for one? About the cheapest I've seen (haven't looked THAT much) was around 25 dollars for maybe 60 or 80 GPH. Also, with this type of build, would it be better to have an oversized fan or an undersized fan? I had some difficulties with an ice to air chiller due to the fan being oversized, and air just redirecting upwards outside of the fan blade radius(it was a box fan, and air came up in the corners, basically. Bypassed the styrofoam cooler entirely

Instead of using ice water how difficult would it be to just use R134A refrigerant which could be rechargeable?
hi. i've never worked with it before. do you have to be certified to use it? maybe an ac tech can jump in on this
You have made several chillers now, so in your opinion what is the most effective one? Thanks again!
hi. in terms of pure power the strongest ones are the ones with the large copper heat exchangers (but those are overkill for some people). this is one of the best in an overall sense. not huge and bulky but not too small either. it has great cooling power, lasts a long time and doesn't add any humidity to the air. the ice-based ice chest ones are really good too (and the evap ones are great if you have dry enough air). here is a link to one of my larger copper heat exchanger ones th-cam.com/video/u0AGRBT1ISs/w-d-xo.html (if you want to see all my heat exchanger ones - i've got a playlist just for those 🙂)
@@desertsun02 Desertsun, thanks again man. I made the chiller with the smaller radiator and 12 inch fan. Worked great! I, going to make one with copper: I watch a lot of great video but you have the best. Keep the video coming we all gain usable knowledge on the cheap man.
Need two of the radiators one for the fan one in the bucket covered in ice and just recirculate the water with maybe some coolant. Or you could even then freeze the whole bucket in a deep freezer.
Coolant is deathly poisonous and unnecessary.
More experiments are in order. Use a small spacer or smaller piece of hose inside what u have to create a restriction to slow the flow down a bit. Try it in different spots.take temp readings again
hi. i've got lots more done already. just need to edit it up ✔🙂
If I froze a gallon jug of water and dropped it in the bucket, do you think it would last thru most of the night? I think i could use this!
hi. hard to say. you'd have to experiment and see. if it's not too hot and the fan is run slower you might be able to (or use a couple of frozen gallons)
Put a couple of heat sinks in between the fan and the radiator may reduce the need of ice in the bucket.
