DIY 12V Air Cooler! very cold air! 20w (AC or DC) - Radiator w/Stand + Hi-Speed.Fan! modular design!

How to Make a Powerful Desktop Air Cooler at Home. this DIY AC Air Cooler combines my recent Hi-Speed Fan Project with a Cooling Radiator and DIY Radiator Stand. Very easy to set up! Unit runs on AC or DC power! 2 speed operation. produces cold air for hours at a time. very low power draw, *15w on low speed, *20w on high speed. maximum amp draw is only 1.6 amp/hrs. per hour (1.3a for the fan and 0.3a for the pump). runs on AC power using a 12v 2a (24w) transformer (only $5 from amazon) ...or on DC Power using an autos 12v power socket, a 12v solar panel or a 12v battery. compact and very durable. good for use around the house or 'on the go'. note that the fan and radiator are not attached in any way (they just slide together) so you can always use the fan as a stand-alone desk fan if and when you want to. note also that the radiator just slides out of the stand (so the unit can be stored easily). output air temp on high speed 55F/13c (with 80F/27c room temp). that drops down another 10F when you run unit on low speed. ice jugs last 3 to 4 hours (just rotate in and out of as needed). for extended cooling times use larger ice chest and load it up. using multiple ice jugs/ice blocks/blue ice packs could easy get you 8 10 or even 12 hours at a time. if you have condensation on the radiator, I'd recommend laying a 'hand towel' or paper towel underneath the unit. parts list is included in the video. feel free to comment and to ask any questions in the comments section below.

Love the old school YouTube vibe, pls never change your style.

I built one of you cooling inventions and it works so well. Btw, I'm in West Texas (extremely dry and HOT) today it's 112 degrees outside and inside we're at 76 degrees plus we get the added benefit of adding humidity.

Honestly man, probably the best eco friendly invention channel on YouTube.

Another great "dry" cooling system, thanx.

Awesome to see, thank you for your continued innovations! Saturday night I caved and bought the parts to build the Deluxe Air Cooler that you posted 9 months ago. I live in N.C. where it's not super hot nor dry, though this system should work beautifully regardless. I cannot wait to use it when we lose power, and when camping to show friends. Hopefully it can also save me money in the long run by supplementing my HVAC load.

So glad you list out the components. I might try to build a smaller one since I have a small fan and radiator around, just need a pump.

A twelve volt fridge freezer that works from a solar panel would be an Ideal companion for your set up. 👍

[SanjabarRogers]

I really appreciate you sharing your innovative ideas .
It looks like you could cool your house with multiple fans and air coolers that you have built over the years . Thank you again and much respect.

I wonder if a used mini-split indoor unit, instead of the trans-cooler, will be more effective?

Instead of cooler with ice, what about using a used chest box freezer connected to solar panels?

[fabiorinaldi]

Hello, thank you for sharing. Can you please tell us for how many hours the cold air lasts? It could used in indoor grow tents but i would like to know if a block of ice will last for an entire day, or if you have to change it at the middle of the day. How much was the temp of your room before and after starting the cooler? Thank you

[Talvish]

Nice. How many hours does it stay cold in the cooler vs a regular 5 gallon bucket? My pump is slightly bigger as well

[TallPaul]

Another great job. Well done!!! Glad I subscribed years ago.

[Electronzap]

Very cool. Would be nice to set the radiator on a night stand while sleeping.

[johndevries]

Hi Desertsun, you have delivered another great piece of work. But am I right that you made something similar a few years ago, this is of course in a more modern guise. I still have a question, I personally find that hassle with ice difficult, you have to keep adding new ice and remove the melted water. As I wrote to you before, this may be possible to compensate for this with 1 or more PELTIERS, you must of course have a drain to the outside.... Just a question. Greetings from Rotterdam.😉

[tobyz.]

Very Cool man. . . !!! No pun intended.
I think this is great. What size SOLAR PANEL were you using in this video? Running direct?, no controller?
Thank you in advance for your response.
OH OH OH . . . BTW, I am going to build your design using the BILGE BLOWER FAN. I will contain the coil inside the cooler for recovering condensate.
Keep up the great posts!!

[megandonahue]

Thank you for posting! Im going to build a couple of them and use my box fans. I was just putting frozen 2 2liter bottles in front of a fan but this is much better.

I can't believe I hadn't thought about using a 12V solar source to run my energy generating machine like you did here. I had thought about using a small 12V battery and worried that the energy pulled from the battery would be more than the energy produced by the machine. But using a 12V solar source the energy requirements would be zero and any energy produced by the machine would be free.

Nice video :) the options for cooling are … 1 use ac, need much constant power, cost a lot, result never ending cool. 2 evaporative cooler (swamp cooler) much less power, and uses water, cost much lower, adds moisture to air, wont work in humid wheather, in good conditions will cool. 3 use direect or indirect cold source (ice) low power, uses ice (need some way of making or buying), mostly for shorter times. Simpelest evaporative that i have used sometimes, need fan and wet towel (somithing to drape towel over and drip tray under. Fan blow across the wet hanging towel, towel gets colder from loosinig moisture and air blowing across colder towel cools air. Works maybe 30 minutes to 1 h before towel dry.

How well you think the radiator performs in comparison with the foam evaporation pad for the same dimensions? I would rather use the pad if it means that is more efficient.

[esecallum]

simply put a cloth into a dish and blow air thru it....capillary action will keep it wet and air will cause evaporation
