Ultrasonic fog cooling tower

post #1 of 35
Thread Starter 
Ok, I have one of those fogging dish like foutains and I was toying with the idea of a cooling tower. However I don't want it to be huge and actually want it to be as compact as possible. I realized this is possible if the water volume being cooling in the air is as fine as possible and as dense as possible. The idea is to use a ultrasonic fogger or array of mist nossiles and pump to generate a very fine mist. A small fan would cool the water back into a shalow pool with a series of heat exchangers at the bottem. The actual water that runs through the heat exchanger would never touch the water in the cooler box/tower.

some part im looking at are:
ultrasonic foggers:http://www.mainlandmart.com/foggers.html

Mist nossiles:http://www99.shopping.com/xPO-Mist_C...www.google.com

Heat exchanger:http://www.performance-pcs.com/catal...oducts_id=4131

rad:http://aquastealth.com/index.asp?Pag...PROD&ProdID=24

Does this sound like a pluasable idea or is there something I'm missing. I want to build it and make sure it works right before trying it on a rig.

Only problems I see is getting the exhuast air out without it taking the fog with it. In this case I might have to resort to the mist idea since its not as fine.

As long as it has nothing to do with being a part of a computer, I say its feasible. =D Sounds cool.

well depends on how he does it, im not really sure exactly what hes thinking but i saw some threads on a guy that used a water tower cooling system and it worked out pretty well allthough it was alot cheaper then what digitrevx is planning i think

yes all the water in the cooling box/tower will be completely separate from the computer. only interaction the pc will have with it is maybe to power it and for the WC lines to run through the heat exchangers.

Right now my biggest problem is keeping the water inside the unit because when I exhuast air out the mist/fog will want to come out with it because its so fine.


Basically I need to condence it back down to liquid to effectivly vent the air.

Or if the fans are powerful enough that I can blow bubbles I can force it back into the water. Basically I got whole bunch of ideas so i need to organize them and find a solution that will make this work. I'll try to make a diagram of the basic idea i have now.

If any sufficient amount of moisture gets into the room with your rig, the humidity level will make it extremely uncomfortable and will begin rusting any ferrous metals in your rig.

Any slush box will evaporate too, so as long as I keep the exaportation level close to that it will not harm anything. I'm pretty cleaver so if I really want to do this I'll find a solution. I may just have to channel the fog to another part of the unit for it to condense and cool.


I know what parts I need but the design of the box and how I channel the fog will be key to making this work so this is the hardest part to overcome.

I made some 3d quicky renders of the concept idea i have now. There are 2 things that worry me. 1 the amount of water I'd have to use in this design and the fact it will be held togeather with apoxy. Then the second thing is I'm not sure how far the moisture will travel in this design. If I use 2x 90mm 45-59cfm fans I'm not sure how much fog will make it to the upper exhuast vents. I'd rather most of it settle in the pool again.

my foutain isn't working right at the moment because of the float switch so i ordered another to play with till I have a better understand of what I'm dealing with.

I like the rad position on this design though because it should ensure a even flow of fog and air. The fog likes to sit on the bottem so I hope this design will take advantage of that effect.

I'm also going to try and start out small to make sure this works. There are industral size ultrasonic foggers that are as mch as $400 bucks so I'm going to start out with a $26 one. If that goes well I'll up it to a $80 one thats 5 times more powerfull.

Im not getting the concept here...
