Building my own swamp cooler!

post #1 of 7
Thread Starter 
Hi!

So, I want to build my own swamp cooler! We don't like using our AC because it's just so costly. But it does get around 86F (inside the apartment) which is just too hot. So I got the idea of making my own swamp cooler.

I don't want to buy one, so here is what I was thinking.

(see attachment)

I want to have a large res, like a metal tub, filled with water and an extra XSPC pump/res combo I have to pump water to a res ontop of a swamp cooler filter. At which point the water would be distributed down the filter and it's micro fins, and gather back down in the bottom res to start over again.

All the while a fan will be blowing through the fins from behind.

Problems:
- how to power the pump, as its molex.
- how to distribute the water from the top res evenly across the swamp cooler filter.

What do you guys think? What can I do different? What just doesn't make sense or does make sense.

Thanks!

first, 84 is not even close to hot. i'd iike to be where you are now.

on topic, if you plan on making it big (like a decent sized cooler for your room, make sure those pumps will push enough water through to the top of the filter. also it doesn't collect in the bottom for very long because it evaporates. you'll need to have a constant water source or just refill it periodically.

bigger models have hookups for a water house, and a nice sized belt driven fan, so make sure your fan is strong enough to push or pull the air from the wet filter.

good idea though. post pics along the way.

this is very true. I'm in the high desert. It was 100 today. If you dont have a constant water supply, you will be filling it constantly. Before I hooked my swamp cooler to the water line, I'd refill about every 2 hours.

Great suggestions!

But I doubt a tub of water will evaporate quickly into a room. The hooks ups to normal swamp coolers I believe are very small, and only require a small stream of water, maybe I am wrong, but about 20 gallons of water? I don't see that going anywhere fast though you are right, I would have to refill it as it evaporates.

Edit: I may be very wrong about evaporation rate, how much do you feel you had to put in to fill your swamp cooler every 2 hours?

Also, I have lived in the high desert for 20 years what part are you from? so yeah I understand hot, and maybe I wasn't clear. It is 86F inside my apartment, with obviously no breeze.

if you live with inside temps hotter than 86 I'd like some proof

Elma, every good Tucsonan knows all about swamp coolers, this is the land of swamp coolers. One thing about swamp coolers is they put so much moisture in the air rust can get to be a problem. With a house swamp cooler you must store your firearms (well most of them) in some other place but in the house. One season on the swamp cooler will just about ruin the bluing on a firearm. You must keep them out of the house or keep the metal heavily protected.The damage a swap cooler can do to your favorite firearm can just about bring a man to tears. Let us see how far you get,or were you really just joking?

Hahaha, good to know! I really had no idea so much water evaporates, wow.

And yes, I am serious looking for a place to get a swamp cooler filter in my small town this week

The pump is easy to power, it's just a 12Vrail, you can either run it off a wire from your PC or alternatively you could buy a small 12V PSU, you may even have a convertor plug lying about the house you could use, for that pump requirements are pretty much:

12V and >1A

I would look at 2A+ though. (and don't wire it the wrong way round or you'll prob kill it ~good way to test that is with an LED if there's any doubt; cheap and effective )
