View Full Version : New idea USING condensation

Sound wacky? You bet!

Here's the Jpeg.

Works this way:

1. Hot water is delivered from the wherever, misted into a fine spray and blasted against the piece of sheet metal bent into a curve with fins installed.

2. 7v 120's cool the fins and thus the sheet metal, forcing the misted water to condensate on it and then collect into cool droplets then head to the water trough.

3. water travels down to trough, goes through filter, then to reservoir.


First off, what is the feasability of this? I thought of it while trying to make a quieter waterbong (didn't like the idea of three or so men ****ing constantly through brillo pads).

and if it IS feasable, think it could be shrunk enough to be able to fit on top of a case? or on a flat side to a limited extent?



or is it just completley retarded :-D

it IS evaporative cooling. condensation requires evaporated water(your confusing mist with evaporated water, they are not the same) to condense on a cold surface, which will actually counteract it. takes energy to condense it.

I didnt follow the analogy, the bleeping maybe but I dont see how a bong sounds like a guy getting it on.

either way, you could put some insulation around it to keep it quiet.

It is feasable though, minus my misuse of the terminology?

well... feasable yes. but the benefits will be limited I think.

your limiting your surface area of air on water by blocking it with metal. I plan to use a stuffing in mine to slow the descent but I think its important that it only slow it, not cascade all the way down on it or it never gets full contact with the air.

also you may have thought of this but not said it. but your specific plan calls for a mist, I too thought of that, its so obvious as having the greatest surface area, and the slowest descent and least sound.

the problem is, the slightest breeze from a fan will carry most of it out of the chamber. drops have to be large enough to continue to fall despite the opposing breeze.

well, the drawing I provided was only a basic one, if I build this for real, it will more likley than not be closed off, or be a cone.

Sounds noisy. Sprinkling water? no thanks. you may have a mess too.

Then you have to refill system all the time due to evaporation. what a Pian in the butt.

It a good idea though.

thats the problem, it cant be closed off, well... maybe I missed the idea here.

as Im thinking your blowing air through the area where the water is misted, thus is cant be sealed off, or how does the air escape.

but... if you had the heatsink double sided, and the fans blew on the opposite side...

but then its essentially an incredably inefficient radiator.

Your really making more of a phase change heat sink than a "bong".

a very big one though....

the whole thing is based off of the principles of condensation. the 'heated' misted water would be sprayed into the air. it would then evaporate due to the tiny water particle size. then it would float up into the metal shield because warm air rises. after it hits the shield, the heat energy would be transfered to the metal shield via convection. the heat from the shield would then be dispatched via the heatsinks and fans on top of the shield. finally, the water would drip down off of the shield back into the res.

the loop could be open or closed i would think because the heat would be transfered off of the shield, not from falling water particles like bong cooling uses.

rule of thumb to help test ideas.

all heat goes somewhere, and in ANY system that heat goes into the atmosphere.

now evaporative cooling is a unique case as it goes to the atmosphere but in the form of evaporated water rather than heat. the water carries the heat.

but so long as the system is sealed, your not using evaporative cooling, since any and all water your evaporating your recondensing, eliminating that factor.

in the end, your system is venting to the atomsphere via the heatsink, making your perfect case as good as the heatsink can transfer heat to the atmosphere.

in a round about way everything is nothing more than air cooled heatsinks, be it a radiator cooling water, or a cold find condensing air(though I think 99% of the cooling will end up being water on a cold heatsink, not condensation)

and once its just water on a heatsink, its a radiator, with water on one side of the metal and moving air on the outside.
