DIY Air Cooler! w/Tubular Radiator! High Airflow! New Design! DIY AC Air Conditioner 12v can b solar

DIY Air Cooler! DIY AC Air Conditioner! New Design! w/Long Tubular Radiator. High speed and Powerful. Cools for hours at a time. can be AC or DC powered. low power draw (about 45 watts). works excellent. can be solar or battery powered, if desired. video shows lots of temp readings and close-ups. be ready for summer! the "how to make it" part is shown at about the halfway mark of the video. output air temps in an 80F (27C) room averaged 54F (12C). air speed averaged 33 mph (53 km/h). please share around with everyone you know... any questions, just drop in the comments and i'll get to them shortly.
couple of unique things about it...
1.) the ice chest is not damaged in any way (it stays in 'like new' condition) so you can use it like a regular ice chest any time you want to.
2.) the entire blower/tube assembly comes off the top so you can carry it around and use it with any other water source that you like.
3.) it's the strongest DIY AC i've ever made (the most efficient too). two gallons of ice produced cold air for over 3 hours.
4.) also, has the fastest air speed by far of any Air cooler i've ever made. shoots the air all the way across the room.

I grew up in the 60's and 70's with "swamp" coolers and I love your dry cooling devices. Thanx.

[@desertsun02]

hi and thank you! yes, this type of air cooler is a 'dry' cooling device (dry meaning it's not an evap cooler). i guess you could call it an ice based phase-change cooling machine. adds no humidity to the air.

I would like to thank you for posting the video on the swamp cooler with the transmission cooler. I built it exactly as you described, and I use it in my RV. It works fantastically. Thank you so much.

[@desertsun02]

hi there. i'm glad you made it and it's working good for you! that's what it's all about 👍🙂 .....just a quick note for clarity: a swamp cooler is something totally different. that term is just another name for an 'evaporative air cooler'. those air coolers use water-soaked pads (but no ice). the ice-based air coolers are 'phase change' air coolers. {as ice melts (or as it changes phase from a solid to a liquid) the heat is literally pulled out of the air}. (melting ice absorbs heat). the biggest advantage of the ice-based units is that they are 'non evaporative' meaning they don't add any humidity to the air (they just cool it down).

@hurlrules1 hi there. the controllers come and go but you can use lots of different controllers. it doesn't have to be the same one. amazon has dozens of choices. just make sure that 12v is within its range. i think the range of the one i used is 7v to 40v). also make sure that it handles the amps. the one i used handles up to 10 amps. the unit pulls 4 amps or less at most so the controller handles it with ease 🙂

Hello sir, I wanted say thank you so much for sharing this idea on youtube. I'm a fanatic when it comes to staying cool and I am paranoid about getting hot while sleeping during the summer. This is exactly the kind of design I've been trying to figure out to go with and I'm going to go with a 24 inch transmission cooler to take it to the extreme. I really like the design you made here, and it will definitely serve as a foundation for some extra ideas I have. Before discovering your video, I was contemplating on getting a 20x20-in aluminum radiator for a car and slapping it behind a 20 inch box fan, but I actually really like the idea of using a blower motor with the aluminum cooler like this. Again, thank you so much for brainstorming this idea up for DIY folks like myself to incorporate at home. It gets miserably hot and the summer here in arizona, and a cooler like this is exactly what I need to keep the edge off while trying to sleep. Look forward to seeing your other ideas! David

I think this is the better option for me because in a camper van in Australia i don’t want to add moisture in the van like the air over the ice options out there. I did think the only changes id make and id love your thoughts, was to add a stainless steel reservoir inside the cooler using antifreeze in the lines so it can go colder than freezing and hopefully keep the ice frozen longer.

[@desertsun02]

hi and you're welcome! i thought about using a 4 inch dryer hose or 4" piece of PVC pipe but was afraid that too much air would pass too far from the fins to effectively cool it down. i'm glad it's working for you though! if you ever want to try and get the temps down even further consider making the 3.5" pipe (like the one in the video). super easy to do and it keeps all the air even closer to the cold fins. btw - i'm just finishing up a similar build that i think is honestly the best one that i've ever made. it even beats this one (by a little). it came out fantastic! it's got a built-in air filter, a built-in radiator and a fully adjustable (360 degree) air outlet (so you can blow the air exactly where you want it without moving the ice chest. breeze is 15 to 20 mph and it runs quiet. it's all 12v too! total power draw is just 3 amps (36 watts total). i just got 4 hours of cooling using two ice jugs and 2 blue ice packs. (with 80F/27C ambient air temp). i'm in the process of editing the video and will post shortly. note: that unit uses similar components to this unit so you can convert this unit to that unit with just a few tweaks (if you wanted too).

The oil cooler as the heat exchanger is an excellent choice - it makes it very DIY friendly. Can you use some flexible duct pipe (like you used for the silencer) around the heat exchanger to guide the air over it rather than the wire mesh construction? I wonder too if you could pre cool the air with an evaporative (swamp) cooler to reduce the ice consumption? The air flow is already there as is the pump and piping...tap into that water and pipe the water to a suitable media perhaps?

Hey check this out, if you go with the 4 inch sea flow inline, The 4 inch sewer pipe makes a perfect tube! Im using a heat gun to make flat spot for the cooler and the inline with a gasket locks into the flanged side of the sewer pipe for a nice snug fit! you now have a perfect wind tunnel thats way more efficient and sturdy and just a clean look. Im going to also do mine closed loop and use antifreeze with a flat transmission cooler that fits the bottom of a cooler. then water and crushed ice on that then layer of cubes and then dry ice and then blocks over that inside one of those yeti type coolers but walmart has some that are way cheaper but have same performance and USA made.. You have really inspired me on this because I do a lot of camping and stuff like that and I had something close to this but it was ugly and bulky. but trust me on the closed loop two radiator system it really runs so much better because the water friction isnt being exposed to the ice. I know it sounds weird but running water produces heat but when closed away the heat is way less. when the ice melts around the dry ice it seals and acts as a pressure vessel and the CO2 forces into the ice and doesnt dissolve as fast in fact wrap it in paperbage tight as you can then get it wet and it really seals it up. Thanks again for the long transmission cooler idea I didnt think those existed. I should have known but thats life take care

Just remember that all the heat you remove from the room with this air conditioner is heat you previously added by freezing the water (and then some, since the freezer isn't 100% efficient). This isn't that bad necessarily, since some of that time will be during the cool night / early morning. I still think a window AC unit is probably a better choice for most people / situations.

Window air conditioner uses a ton of power. South Florida we are paying 400-800 month depending on your house size in electrical bills.

[@MrDarkdaze]

Aren't you doing the same with a window unit? Aren't you, in a way, transferring the heat from the room to the outside? Don't window units also blow air across some sort of a radiator filled with a much cooler substance, albeit one that was cooled after spending 50,000 tons of CO2 emissions compressing the substance to make it cold? I'm not an engineer so maybe I just need to stay in my lane.

[@MissBforBella]

Pretty sure folks are already operating their freezers so making ice doesn't add entropy, it just uses the existing entropy more efficiently.

[@fgbhrl4907]

@@MissBforBella Of course it does. Think about it; why does a freezer compressor ever run? It's to extract heat out, until the compartment reaches a given target temperature (-10 deg C or whatever). There are two sources of heat: Adding warm stuff into the freezer, and leakage due to imperfect insulation. If you add something warm (water), it will warm up the compartment. At this point, the compressor starts running until its able to bring it back to its target temperature. The more warm stuff you add into the freezer, the longer it takes. In this case, you're only going to reach equilibrium when the water is frozen.

[@chriswingertjr5538]

I think you missed the point here, this is a portable AC that runs on a 12-volt Supply, it can be used anywhere, in a tent in a mountain house that only has heat and is not normally used in the summer, I don't think he's doing it to compare it to a Shaker unit

Do you set the temp just over freezing so the pump doesn’t freeze?

[@trishoakley6730]

I did the same thing. Smaller freezer fridge runs off battery or outlet. Filled with frozen water bottles. Set on below freezing the water returning has some heat. This helps keep the unit right above freezing. Used insulated vent tube over radiator 4 inch with solid connectors and c clamps helps with fan noise. 180 pump, for fan - convertor with fuse battery to outlet, fan added toggle on/off, speed dial, male cigarette plug. Modified fridge/freezer unit with drilled holes used boat thru-hull connectors to least amount of hose in open air reduces condensation on hoses dripping. Also reduces loss of cold air in freezer/cooler unit with running to recover temp stay cooler. I built 3 of these cools most of my mom's house here in South Florida without adding humidity to the area. Frozen water bottles keep about 4 days. You can add some alcohol to water and the freeze point is lower. Let the pump run to really cool the radiator before turning on the fan. Whole build running less than 100 watts, moveable on dolly, 3 outlet plugs on power strip all tie strapped less clutter plugged into 200 watt jackery on one to 200 watt panel runs free during day. These are stationary so built according. Fans are noise but you can sound deadening foam and wrap muffle it out.

[@dfleming9665]

Where does the condensate go? If you’re in a humid environment.

[@desertsun02]

hi. it can form on the radiator tube if the humidity is high but it just lands in the bottom of the tube. if you have a lot of condensate a few drops might run out. i'd just place a paper towel at one end of tube to catch that if needed.

[@zwarst]

I can see a heater application using thermosyphon.

[@zwarst]

@Goodness same as, yet with hot water.

[@user-pn3ly6sl1e]

I use my AC for allergen filtration as much as cooling. I wonder how much more energy I would need to blow air through a filter.

[@desertsun02]

you could install a 'cut to fit' filter on the back end of the blower pretty easy. i almost did that with this but didn't want to overcomplicate the project. i don't think you would need any more energy. the breeze may be slowed a little but it wouldn't matter. the thing really moves a lot of air.

[@Sourpusscandy]

Hi can you please post links to buy the fan and radiator. Thanks!

[@Sourpusscandy]

This?

[@truthseeker9688]

Awfully loud...are there quieter options?

[@desertsun02]

hi. that's just the cameras microphone. it makes it sound louder than it is. it just sounds like a strong fan running when you're in the room. i've fallen asleep to it twice already. nice smooth sound. you can always add a speed controller switch to it if you want to (one shown in video) or the 'muffler' (also shown). best way to think of it is if you don't mind the sound of a box fan then you won't mind the sound of this.🙂

[@briannavanleuvan1395]

Is this for sale? Uf so how much is it and how much would it cost to ship to southern California?

[@desertsun02]

hi. i don't sell them, i just show how to make.

[@professionalservices3603]

If you were using this to cool a large area would it not be better to get the longer 30" tubular radiator?

[@desertsun02]

hi. possibly, but that might be 'oversized' unless you use a bigger ice chest too

[@maliqueassad9332]

Great idea! This goes in a house, right? What would I need to make it work in my 1970 Chevelle until my vintage air kit arrives???

[@desertsun02]

hi, yep it goes right in your house (or your car). the fan is 12v so all you need is a 12v pump and then you can plug those into the 12v power socket (cigarette lighter) in the car

[@cinobyte]

I am curious why you chose to have the blower exhausting towards the lines vs flipping it around so that its pushing air passed the radiator any reason or just choice?

[@desertsun02]

i'm not sure i understand your question. there's no room to put the fan on the other side (where the tubes are) because they would get in the way of the fan. or am i mis-reading the question?

[@cinobyte]

@@desertsun02 I built one similar to this. What I did was flip the blower around so I could connect "duct" to it. That allowed me to direct the air flow in different directions or in my case split the air output in 2 directions

[@frontrowfantic]

any condensation from the radiator that I need to account for?

[@desertsun02]

hi. i don't generally have the condensation issue where i live but if you do it will just drip down into the tube. if any runs out you could just wipe it away with a paper towel (or fold a paper towel and place it near the end of the tube)

[@waynebroussard7676]

How can I go from a 110 outlet to the 12 volt bilge blower? What type of transformer can I use. I cant find one anywhere around here. Home depot, walmart, west marine is where I got the blower from but they dont have a 110 to 12v transformer. Can you recommend one to me?

[@desertsun02]

hi. sure. amazon has tons them. dozens and dozens. the one i use is a RoyPow 12v 15a one. the unit only draws about 3 to 4 amps total so i would say to buy one that it at least 6 to 8a. that's so it doesn't run at capacity. or get the RoyPow one. i have had it for many years.

[@waynebroussard7676]

@@desertsun02 Awesome! Thank you very much. I love your show. You are a genius when it comes to DIY.

[@deaddegenerategeneration7441]

Where do you even getba radiator like that

[@desertsun02]

hi. that radiator is from amazon. it's a flashpower transmission oil cooler. make sure to buy a 'double pass' one. a 'single pass' won't work (because it's got tubes on both ends).

[@chrisparker5895]

What’s the secret to keeping the ice from melting so quickly?

[@tonymengela3575]

freezing in milk jugs obviously

[@tonymengela3575]

dry ice on the bottom with thin cardboard to insulate it would extend the life

[@trishoakley6730]

I am going to try it in cooler that plugs into car cigg lighter that stays cold like a fridge. You see them in RVs, van builds etc

[@desertsun02]

hi. if you add the optional speed controller and run the fan slower, the ice will last even longer. or freeze 4 gallon jugs and you may get 6 or even 8 hours. i got close to 4 hours before it really started getting warmer.

[@didymario]

The humidity has to be very low otherwise how do you deal with water droplets due to condensation?

[@desertsun02]

hi. there may be a little condensation (but much of it will actually re-evaporate with all that wind blowing across it) so you will never notice it. if any does form it will just be a few droplets - so no biggie. the tube itself is stainless steel mesh and thick tin foil so that works well too

[@eone2345]

I think install sump drain below it and let it drain inside the cooler box is easy option

[@desertsun02]

@E One interesting idea, i think people will find that there is very few noticeable droplets. shouldn't be an issue. just slip a paper towel under the end of the tube if needed. that would soak up any. that way you can keep the ice chest in new condition.

[@eone2345]

@@desertsun02 it was because of my past failed experiment. My country has very high humidity and hot weather, so the water got pool up in no time

[@desertsun02]

@E One i'd just try the paper towel near end of tube if needed. it should work good. i've lived in super muggy places too. i'm glad i got out of there. drier is better imo

[@ChefDuane]

How much to make me one?

[@desertsun02]

hi. i just show how to make, but i don't sell them

[@carlitospc]

Someone should start a contest on best way to cool a small hot room. Maybe a $$$ price for incentive. Surely something cool ;-) will result!

[@AliHassan-mh2gh]

Why don't you try this

[@deaddegenerategeneration7441]

Could you do a video on how to build my own radiator semi like this tube one

[@desertsun02]

i do have a video or two on how to build a radiator (but not a tubular one). i'll look into making one.

[@stevow1987]

Lol grandma's boy at grandma's house.

[@toyomoma.6841]

Question so this can be specifically made for you car correct ? And do you suppose it will still be able to run for 3 hours straight hooked up to the smoke adapter ? Asking for my husband

[@desertsun02]

hi. yep you should be able to run this using a cars 12v power port. how long the ice will last will depend on how much ice you use, how big the blocks are and how hot the ambient air is. if you have plenty of ice you could run it 24/7.

[@RickJamesBitch369freeyourmind]

Doesn't it filled up condensation what do you do about that? How are you draining it?

[@desertsun02]

hi. i don't have the condensation issue where i live, but if you do it should just pool in the tube. it might run out after a while but you could take of that with a paper towel

[@RickJamesBitch369freeyourmind]

How much was the total cost to build that???

[@desertsun02]

about $100 - (not the cheapest one i've made), but it's powerful and long lasting. i've seen similar units for sale at over $300 so it's much better to make it if you can (plus if it ever breaks you'll know exactly how to fix it (since you made it).
