Ultrasonic fog cooling tower - Page 2

post #11 of 35
1. About holding the box together, use silicone. Go to a local pet store, look in the fish section and buy some silicone. It's the same stuff they use to hold giant fishtanks together. It will hold. I used to help build custom fishtanks with my boss when I worked at a huge pet store.

2. Have you put your hand close to fog machines? Your hand will usually become noticeably wet pretty easily from the humidity. If you really wanna move forward with this, you need to keep a very close eye on condensation.

ok, keep in mind its in early stages but just below the 2 fans is a ultrasonic fog generator. It will turn the water into micro droplets without adding heat. The fans then boost the thermal cooling effect and ram it through the rad. Then the idea is to condence the fog back into the pool. Then the cycle starts over.

It will work much like a cooling tower for powerplants but on a mini scale. The cooling will happen just before the fog hits the rad.

I know this idea will work but working with something thats so close to a gass is hard.

When my fog foutain was working the fog was very cool to the touch at only a 4inch fall from the bowl. With fans I think I can boost that effect.

I hear silicone doesn't work well with acrylic.. I've read to use plastic apoxy then line the joints with Methylene Chloride to seal it.

Yes i do know what will happen. I already own one of these things im talkin about and has alot to do with the where i got the idea. The goal is to use the mositure creat a superior heat transfer effect than regular sprinklers and misters used in current cooling towers.

Please also keep in mind the unit is not going to be close to the pc. I know what it can do to it. So far everyone thinks im putting this thing in or next to my pc, but for the record I'm not that dumb, lol.

lol i just got a idea to maybe solve mass mosture escaping. Maybe a all weather heavy duty foam filter that can be replaced.

I've known people that built with acrylic and used silicone and they never mentioned anything to me. However, a lot of the people I knew built their own skimmers for saltwater tanks and they used capillary cement and viscous cement. And now that I think about it, solvent cement is recommended for joining acrylic. Plenty of guides online regarding capillary cement and viscous cement application.

As for the project's function, I still say watch out for odd occurrences. The upside down smilie face was a note of sarcasm. I know you own a fog machine, I read the thread. Using fog and its byproducts as a cooling method doesn't sound very worthwhile to me personally but if you try this, make sure to document it all so we can follow your progress.

yep I sure will, but I admit I have much testing to do before I waist my time building this. I know it has to be a dense amount of this stuff to make a diffrence really, but if the odds are it wont work I'll give up. Right now it just looks like some engineering problems I have to figure out.

If i went with mist sprayers it would have a whole new set of problems like pumps and things. I'll let you guys know what I find out when the new fogger comes.

Also I'll double check on what I use to bond the acrylic before I sit down and do it. So far I've loost nothing and only have more to gain.

Hey Dig, WOW...This is wild....Get some of the plexi cement that they use for aquariums it will be fine......I've never heard of any one doing this...Which makes it interesting...Google "Bong Coolers" which is a different concept then this, but I think you may find some useful info that you may want to use in your plan....They use PVC pipe with a shower head in the top to atomize the water, the bottom is the res and pump housing...They also use a fan blowing across the spray for extra cooling....Good Luck on it.....EDIT: I found this for you on bongs...I guess some people are still making them, cool.....Bong Designs - XtremeSystems Forums

Hey thanks alot ira-k, the link is very helpfull. I read through it all and it kinda strenghtens my other solution to the fog escaping, by using misters or sprinklers to condense the molicules back to the pool. I also like the design of this alot: http://www.myfoto.com.au/Photo/snapp..._bong_pics.jpg

The only hard part about this design is finding a place for a rad. But with some strong fans this is completely possible with fog. I might have to re-think my design and go with pvc after seeing that water bong cooler. The chances of the leaking are very low and the construction is very simple!


Another worry is the droplets formed by the ultrasonic fogger are about 5 microns across so it could be soo fine that it wont cool as effectivly as I wish. When I get the new fogger I'll know if the idea work or not. I'm hoping the droplet size will allow the heat transfer effect take place faster because the surface area of 50micro droplets is much more than 1 rain drop. Its kinda like a heat sink with fins vs. a solid copper block.

So i dono I'll see what happens when the new fogger comes. Rep+ for the info it helped

That is one giant bong in your link...Nice....Like you were saying the fog may have to small droplets...But then again when your out in the fog the cold goes right through you...Just have to try it I guess...I'd go with the PVC pipe to, easy to work with cheap and it has all kinds of unions for it....Keep us updated it sounds like great fun....

yeah its huge, but im thinkin a scaled down version of it. If i use the alpha cool passive rad tubes they are only 16.8inches long. So i'd estimate the tower being 24-27inches high and the total high of the unit being around 30inches.

ok guys I have a new plan. I wish I had a scanner to post this drawing of the idea. but Imagin that huge waterbong cooler only half as high with dual fans at the bottem blowing up. Also there will be 6 hoses that connect to the top and run down to the base pvc section. There will probably be vent holes in the very front of the base section.

Also there will be a set of 2 alphacool passive rads suspended in the tower section.

This design will not let the fog be recycled so it has to return to the pool to reach the fogger to become fog again.
