AC using an aluminum transmission cooler $22.00

a small water pump, a small fan, a bucket of cold water

  • in description

the model i used was the 401 hayden transmission cooler - cost about $22.00 dollars.

— i get them on amazon. just search for hayden transmission coolers. they have lots of them

— if you search hayden transmission coolers you will be lots of them. the 3 models i use are the 401, 403 and 405. if you like those square fans, those are axial muffin fans. many of those on amazon too

— case fans, here's the low speed one

link to amazon in the video description

 

note the unit is all aluminum so it is extremely lightweight (less than 1 pound), and the whole setup uses very little power. the AC fan uses as little as 9 watts and the DC pump is 3.6w so the whole unit runs on less than 15 watts! note that 12v DC computer case fans (of the same physical size) only draw about 5 watts so then you can run the whole setup on less than 10 watts! for off grid use all you need is one 12v (10 watt or higher) solar panel and you're set. if you like the video please rate, like, comment, and share it around

— i just place the fan either in front of or behind the radiator. i didn't attach it

— aluminum or copper work about the same. only real difference is aluminum is lighter and cheaper

— unfortunately all the peltier based water coolers that are currently on the market are not strong enough to make this setup work (or not for long). these radiators overpower there ability to cool the water within a minute or two and the water warms up (then it just blows room temperature air). i wish this wasn't true - but so far all of the videos that i've seen on making 'peltier based' room air coolers are not true. the best that peltier can do is extend the time that the ice lasts.

— Peltiers are horribly inefficient compared to compressor based coolers. They pump out a ton of heat for the cooling the do. You need a pretty large cooler on the peltier, or the cold side starts heating up too.

— Dry ice is -80 C, that would very quickly freeze up the water in the loop.
