Convection Cooling Tower ?

post #1 of 5
Thread Starter 
Hi I'm new here ( With my name in leetspeak because of the availability tongue.gif.) , been lurking for quite a while but never registered. so this could be considered my introduction.

I've been wanting to share this idea for quite a while. Its basically a rectangular shaped aluminum grid like this ( 10×10 ):

201

Which is stretched out in the shape of a tower to form small chimney's ( think 20×20×50 cm in total or half that size). Ideally you'd integrate a helix through which the hot water is pumped or in my case you'd drill some channels for copper tubing to exchange the heat to the tower since I have no idea how to do the helical shaped thing ( although maybe with a 3d printer ).

Now of course if you elevate this thing a few inched from your desk: as hot air expands it will be expelled through the top, this would suck in cold air from the bottom, the more heat the more this reaction can self sustain, this is the stack effect found in chimneys and coal power plants. This could potentially be a fan-less design. With some modifications the shape would allow it to be integrated in an atx case. Please note that this is just an idea and I have never tried it before, but plan on doing so in the near future.

Its just that I would need quite an amount of aluminum to create this, also I think it would work best if the connections are seamless so practically you would have to cast the aluminum into a mold.

What do you think of this design, why would or wouldn't it work. Also what would be your approach if you would alter this design ?

Way, way to short, and you don't need the "inner chanels"

I'm assuming you want to use a "stove pipe" sort of thing for cooling. Well, to generate enough air flow you'd need something like a 3-4" diameter pipe 3-5' high. As for adding "water cooling" to remote the pipe outside the case, the pump would likely generate more heat that the pipe would remove.

Basically what you're reinventing is the type of heat transferring between most any heat sink and it's radiator, with the evaporating liquid filled pipe replaced by an air filled pipe.

This has been done. See Procooling.com (an old, dead, but very informative) site.

My idea behind the inner cells would be to create more surface area for the air, I didn't mean evaporation water cooling towers like those used to cool nuclear power plants. This could be regarded as an ordinary radiator but then upright ( a fan can always be attached on either sides ).

But your probably right about the pipe being too short.

Maybe this could be applied on a larger scale to cool servers?

I think I'm not following your idea?
Perhaps you could restate your idea more clearly?

The more heat that is lost (to the inner cells) the slower the air would rise.
Adding fire inside the tube would be the thing to do to get more airflow!

Always interested in new ideas, that's how society progresses!

Np mate, I figure my explanation kinda lacks here and there:

306

This is all it is basically...

I meant nothing similar to this:

600
