DIY Space Cooler! "Peltier" AC Air Cooler - 100w/200w 12v (12715 peltier module) - no ice needed!

DIY "Personal Space" Air Cooler! 12v Air Cooler powered with peltier modules. easy to make! good for localized space cooling (200w of cooling power). up to 20F temp drop! it's like a desktop fan that blows cold air! can be used on-grid or off-grid (with 12v solar panels or 12v batteries).
DETAILS:
ABOUT THE PELTIERS: I chose to use two 12715 peltier modules (chips). The 12715 is a 15amp chip and is one of the stronger cooling chips. Note that their 15amp rating is just at startup. it draws 8amps to 11amps during its normal operation (after startup) and has an average watt draw of 100-110w. The 12706 peltier chip (which is more common) can be used in place of the 12715 (if desired). it's a 6amp chip so it's not as powerful but works well too. its average watt draw is 60w.
THE LARGE HEATSINK: The large heatsink that i used is 150mm long but an even longer one (a 200mm or 300mm one) may get you even more cooling.
Room/Space Cooling: note that this unit is a "personal space" air cooler (not a whole room air cooler). The cold air is blown forward (where it's felt) and the heated air is blown to the sides (where it's not immediately felt). *so unless you vent the hot air out of the room the two will eventually 'mix' and cancel each other out.
*Thermal Transfer tapes/glues: Thermal transfer tapes or glues can be used on the peltiers (for permanency) but they're not necessary. that's because peltiers and heatsinks are both made to be 'ultra smooth and flat' so both items lay completely flat against each other. the tapes and glues are meant to fill in any minor imperfections, but I've never found them to be helpful.

Your timing on this is incredible Im mid design on a Peltier based cooling system for a friend and came back to your channel for some swamp cooler design review for part of that project.... and here's a peltier solution with the power supply i was looking at to boot. Normal problem of needing to vent that heat out of the space but still useful projects as always.

[@desertsun02]

glad i could help! one solution to vent it would be to use a 3 or 4 inch dryer hose. you could slide it over the end of the heatsink, bend it to the shape and clamp it on with a worm gear clamp. then direct the other end of the hose out a window (through a piece of plywood mounted in the window). just drill 2 round holes (with a hole saw the same size as the dryer hose) and slide the hose through or seal it to the plywood the same way i do in many of my solar thermal air collectors and air heaters. note. use a 200mm or 300mm heat sink so there is plenty of space on the heat sink for the clamp.

@@desertsun02 Have you looked into those 40mm waterblocks? My idea (one of them anyhow) was to run an insulated hose (hot supply) using a block the same size as the module. sandwiching two modules hot sides to the same block and running a supply through a wall to a 120mm radiator. Adds complexity for sure... and a pump res combo. Im more or less building an aquarium cooler on steroids. So ive got the pumps, hoses and waterblocks already in the budget...

[@desertsun02]

i haven't done much with the waterblocks due to the added level but i really should. maybe in future vids. sounds like you have a good plan 👍

[@ttucker2010]

Another awesome video! Thanks for this. Look easy to make, and it does the job. Keep it up!

[@desertsun02]

thank you! 👍

[@sunnygunz]

lol your still at it lol,,,,i watched your first ac SIY about 9 years ago lol....food job

[@Cindy4004]

Great! While I would love to see this vented as a whole room cooler, this would be brilliant as is for outside events.

[@desertsun02]

hi. yes, should work good outdoors. if i was going to vent this, i would probably set it up by a window or a door and just pipe the heat out using a "make shift" vent (attached at the ends of the heatsink). to keep the tubing or vent as short as possible.

[@_SMan007_]

Cut a hole in a board and stick it in a window with the cold side facing in. (The heat stays outside and the cold air stays inside.)

[@desertsun02]

good idea! ✔🙂

[@coolmonkey5269]

good project bro❤🎉 sir what if i juzz place 2 frozen copper bottles in front of a normal mini AC table fan ? can it blow cool air while sitting in computer desk. bcz i need time to build these things.

[@MichaelR58]

Impressive, thanks for sharing YAH bless !

[@dogsarethebestfriends]

This looks great for my converted cargo trailer! Do you have links for the parts? (just would want to give you a bit of commission money for your help if you're an Amazon affiliate). I've been trying to figure out a way to cool down this metal box (yes, it has insulation but still...) without having to be on the grid. I have solar and batteries but as we all know the cooling part is tough. A few of these for the dog and me could make all the difference. Thanks for posting this!

[@Talvish]

Nice, I'll be making one asap

[@desertsun02]

sweet!

[@mebolzrsweaty]

hi, the models sold on amazon are those with wires, red and black, no connector, so how do you connect those and to what? thanks

[@desertsun02]

all 6 red wires (from the 4 fans and 2 pelter chips) are twisted together (and all 6 black wires too) then just connect those to a thicker length of wire. (i used part of an old extension cord). then that just goes to your 12v power source.

[@Talvish]

@@desertsun02 thanks

[@mebolzrsweaty]

@@desertsun02 ok thanks buddy keep it up

[@kristelbabal1265]

Could you make a list of exactly what you bought

[@b00stedrust]

So hi, as you seem to have built just about everything ive wondered about through the years....right now im working on a project....project actic air..looking to set sone world benchnarking records even during tje summer as most of us guys set all our recorda during the winter.. right now im top 3 in the world. But im doing it the hard way.. no water to my gpu. No chiller.. only air...so i was dreaming up somethkng.. do you think a heat exchanger, 18x20 1" inlet abd ouylt...submerged in ice bath with possibly alcohol or salt mixture... with some sory of inline fan pushing ait through it...be effective? Right now i have 1.5 " copper baseboard pipr with 3.5" alluminum fins looped into the water bath and back out....all together 4 ft under the water.. it feels lacking... maybe low 50s.. my cousin a plumber his whole life said this heat exchanger with good cold ice bath could easilly push out sub 40 f air... thats what im after... and it eould rrally make these guys mad if i kept passing them on a non liquid cooled setup...anyways i just pipe the air to my pc and have 4 x arctic p8 max fans on the stock cooler which is a vapor tube 13" heat sink...big bertha i call hetmr...and some honey well ptm 7950 temperature phase change thermal putty on the core...and before it asks... no ive never had condensation problems... was running 0 f air in in feburary...it was seriously good setup.. but after 40s it has diminishing returns due to well it being air....so if i could get anywhere near high 30s.. id be sitting pretty and id rather do it without an expensive chiller unit...i also have about 6 more ft of this baseboard stuff a relative has that was left at their jobsite...but idk if its thr fan being too fast or the aseboard setup not transfering enough...? It looks like it is insabely efficient though? Anyways.. i hope somehow this smg reaches you abd you can help me jerry rig something that sets world records and breaks hmthe hearts of the 5,000 $ water cooling setup guys. Cheers.

I made a prototype to cool water without compressor, it reduced water temperature to 22 degree. Now I don't know how to cool air by indirect air cooler? I don't know which Material or mechanism will work on it ? Please suggest me.

[@samm3980]

Wonder how it might perform with water cooling the heat sync rather than air

[@desertsun02]

it would be a good experiment. i stayed away from water cooling with this project mainly because then you have the extra steps with water and water pump.

[@erdemir5641]

I don't understand what's going on. What is a chip?

[@desertsun02]

hi. the chip is a peltier chip (or peltier module). those are the flat ceramic square shaped elements. when power is applied to them one side of the peltier gets very hot and the other side very cold. we are using the cold side to produce cold air. it's a little hard to explain in a comment but if you check wikipedia you'll see a good explanation of thermoelectric cooling.

[@lorenwright3202]

Where is the heat going from this design?? Into the same space your trying to cool? I like this but that’s part is a issue for it working the best it can Btw is this the guy who plays the character of J Rock it sounds like it

[@desertsun02]

hi. optimally, you would direct the heat out, but it works great as a space cooler because the heat just goes out the sides and up to the ceiling.

[@klee88029]

This is Fantabulous, I think that I might be able successful in making one of these, thank you so very much. 👍😘🧓

[@desertsun02]

you bet. yep, it's pretty easy to do. you can do it 🙂⭐
