DIY AC Air Cooler! Homemade AC Air Cooler! (No Added Humidity) - Box Fan conversion Air Conditioner

Powerful DIY AC Air Cooler! Homemade AC Air Cooler with Air Conditioner "like" feel! (no added humidity). Easy Box-Fan Conversion! this thing blows a ton of cool air! the air temp dropped 10 degrees (85F to 73F) in 60 seconds! and within 5 minutes it was blowing 66F air. super easy to make too. all you need is 7 things... a box fan, bucket, small (AC or DC) water pump (4.8w 12v one used), 3/8" ID clear vinyl tubing (10 to 15 feet), scrap styrofoam, zip ties and two 'tube and fin' {hayden model 405} 'all aluminum' transmission coolers). the sheet of corrugated plastic (for the side panels) is optional but highly recommended. only tools needed are a screwdriver, utility knife, kitchen knife and tin snips *no power tools. build time: about 2 hours. to use it just drop ice, ice packs, and cold water (from fridge if possible) in a bucket or ice chest and drop in the pump. the cold water cools the fins fast. within 30 second they are freezing. then power-up the fan. (low for coldest temps) and you've got a lot of 'instant' cold air. box fans move a lot of air (even on low) so my living room (shown in video) was much colder in just a couple of minutes. (note that the fins are relatively wide-spaced on those hayden units so the fan pulls air through them like they're not even there - the fans speed is not affected).
A Few Notes: once completed the unit is very stable and the fins feel like their 'cemented' to the fan. it attaches very tight. (the physical properties of styrofoam allow that to happen). as the zip ties are tightened up the fins and fan grill are pulled together tightly against the blocks causing a type of bond. it holds everything secure so there's no movement, sound, shake or anything. they also allows the whole unit to be made without altering either the fan or the fins in any way. both stay in like-new condition. also, no sealants, caulks, glues, drilling, brackets or anything like that is needed. that's good if you want to move the unit to another fan at a later time. disassembly time is only 30 seconds (all you do is cut off the zip ties and pull the side panels off). *side panels are just held on with double sided sticky tape. if you like the video please rate, comment, sub (click bell) and share it around 🙂

other stats/extra info - the fins are light - combined maybe a pound. (no copper). also drains easy - serpentine horizontal pattern versus vertical. black tube and clamps come with the transmission coolers so no need to buy them. don't use 3/8" clear tubing for middle connection as it crimps up and water flow is affected. zip ties and panels come in white or black so you can match them to the color of your fan for a super slick look. AC pump can be used (i even bought a new one for this project *but ended up using a low power DC one). if you want to do this whole thing on DC i've got a video on how to make a 12v DC 20" box fan. it has the exact back grill so you hook on the fins the same way. a single 12v 100w solar panel (or 12v deep cycle battery) runs that DC fan and small DC pump.

tips:
video tips
1.) to easily install zip ties - bend them in the shape of a V before inserting into fan grill.
hand tighten a little at first (to position the fins) then go around and fully hand tighten them.
2.) to get a flat smooth cut of the styrofoam use a thin sharp knife and saw a lot (push down a little) - let the knife do the work. i used six 3/4" thick blocks (1/2" to 3/4" works best)
3.) remember to use 3/8" (internal diameter) tubing (versus 3/8" outer diameter)
4.) only use styrofoam for the support. wood won't work well. condensation may lead to a rot issue plus it'll scratch up everything and probably move around. the styrofoam creates a bond
5.) use a relatively small pump. large ones (with larger motors) warm up the water unnecessarily fast
6.) run fan on low speed for max cooling times
7.) to extend the life of the ice use an insulated container or ice chest
8.) use water from cold source (fridge etc...) for coldest temps
9.) sticky tape works awesome for the side panels - holds tight but can easily be removed if desired.

so i tried and tested this concept with the non box fan build in my van in the AZ heat.. FUCKEN amazin.. so far im gettin about 50/60 deg F output per 1 gallon of frozen water per hour

Better than a classic air cooler that ads humidity ! Well done

[joshhagen]

I love how you constantly improve on this

[christiyen]

Thank you for sharing your fun yet useful experiments! I used your concept to make a mini-ac for me to use at my son's swim meets... Ryobi 4" fan, 120mm PC radiator, USB small water pump, and small Igloo. It works great! I think I'm going to make the 20" box fan for his swim team to use. It's HOT in TX, and these kids sit outdoors for HOURS... Thank you!

Made it. LOVE IT! I was skeptical at first but i did a test run and was amazed. I tried to get the 403 but they only had a 403 and 405. So I got both and made it work. I may get another 405 which is bigger and use the 403 by itself on a smaller fan. All in all. I am satisfied and thank you immensely for this video and concept.

Also I am using my setup with an ac. I have an ac cooling one room with a high velosity fan pulling cold air from the doorway pointed at the back of the air chiller. So with the water cooling the radiator AND cool air behind and pointed at it, it is supercooling the air coming thru and the ice isn't melting because it's in cool ambient air. But I have another high velosity fan in front of it pulling that supre cooled air into the space i want cooled. It works great. YAAAAY!!!! BTW I am in HOT HELL CENTRAL.... Houston Texas. ARRRRGH!!

Bless you! Thankyou!
God, I MISS Arizona sooo much!!!
I'm dying here in Mo with the friggin humidiyy... I could breath there...people alot more loving all around too🌺🌻🌷🌸🌹🌾🍃

This is even better than the small fan build! I built the small fan and single trans-cooler after watching your video. It works great! This one is next. Thank you so much for sharing your awesome ideas!

[dannyg]

Dude I luv you! No seriously! Our RV is a stove during the Florida summers and with 100% humidity, rooftop units can't keep up. This will absolutely save our life and pocketbook! May God Bless you and your family!

[pigeonpea]

I just ordered off amazon! The trans coolers..cant wait to build this!!

[rockreader]

Desertsun 02, Been subbed to your channel for several years and I'm still impressed by every video you post. I am very glad this unit can be assembled without glues or power tools. : )

Thank you man, I needed a way to cool my quail shed. My birds were getting toasty at 95F, and thats with an exhaust fan and insulated roofing. I have my aquaponic barrel filters in there so i tapped the pump to divert some of the water through this. I have a couple thousand gallons of water in my system so plenty of thermal capacity to spare. Hooked up the fan to a plug in thermostat so its automatic. Got a good 10-15 temp drop and my birds are happy. Awesome idea with the transmission filters as I at first was thinking of using a radiator. This way is easier and less expensive. Kudos man!

O U T S T A N D I N G! There’s a woman who works in the laundry room at my job who won’t be sweating it out this summer thanks to you 🤘🏾

[jimmybrown]

Hey just wanted to take a moment out to say you make some of the little best inventions you inspire me to come up with my own keep going love this

[Lenny]

OMG WOW you are an amazing genius so l tried this at home and it took a little longer because l could only afford two 4-way transmission coolers on an circular 20’’ industrial fan with the metal propellers but boy let me tell you when the cold air started kicking in it would not stop l was freezing and l am in Arizona where temperatures are as high as 95 degrees living with my sister right now who doesn’t like her place no less than 85 degrees let’s just say my room is now a comfortable 75 degrees l can never thank you enough for sharing this DIY I ❤ YOU😊

[ybshadyii]

Awesome especially now with these high heat climate change. I live in Mississippi the devil's back door. LoL!!! I need to figure out these instructions and purchase the right equipment. Thanks Again.

[justinshivrattan]

Do you need to have the window open to use this or can i have it closed. Does it build up humidity?

[jsmith]

Rookie here.
I'm looking for an AC pump. Just want to plug it in the wall and works. Some pumps
don't say what size tubing it is for. 3/8" (internal diameter) tubing is what's needed.
Much appreciated to anyone with an Amazon link. Thank you.

[terrydavenport]

I’m about to scrap my window unit and was wondering if I could rig something like this up with whatever confesses out of that? You can tell I know nothing about the technical terms but I’m pretty good with my hands .

[joeowings]

Thank you sooo much again for all these awesome Ideas, I know it’s summer but I wanna be prepared for winter, I see you have made multiple diy heater videos and I was wondering if you could please let me know which one works best and most efficient? I have a 800 sq ft home. Thank you!

[farmerrobert]

going about this all wrong. bury 55 gallon drum in ground and have 55 degree water year round. no ice needed.
