Thermoelectric cooling reinvented!

8-Ball · 08-09-2002, 10:52 AM

Found this site this afternoon while bored at work. Looks like cooling could get very interesting pretty soon.

These are solid state thermopumps, similar to peltiers, only it appears they are a hell of a lot more efficient.

What do you guys think?

I'd love to stick one of these on my processor, but they are going to be as expensive as hell, from the manufacturing description. Aerospace means $$$ regardless of justification.

Duct tape = $4.
Aeronautical duct tape = $2599.99 (plus shipping cost)

It's the nature of the beast.

muwahahah 2599.99

You can build a phase change system that would be better then that thing for 100 bux.

Although.. this little device has it's size advantage.. I bet the starting price.. if it ever comes to life.. will be around 400.00ish for like a small power chip... who knows..

If the thing works good.. other companies will make dumb little mods so they can make their own versions with out a big patent issue.. and then the price will drop.. competition is good..

Wonder what kinds of Delta-T's we're looking at and how much power they eat themselves,, main reason i dont run pelt already is i cant affor the PSU to run them :-P

I'll sell you my peltier PSU for 75.00 + 25.00 for the 172w peltier .. I really have no need for it anymore.. and I can't fetch 100 for the PSU.. so the price goes down.. and down.. and down..

Have a look at the 'calculator' they have on their site to compare the chips to peltiers and compressor cooling systems.

http://www.coolchips.gi/technology/ccalc.shtml

Put in hot and cold side temperatures and it gives you how much juice your device would need to move one watt of heat from the cold side to the hot side.

As an example, 50 degrees hot side and -10 degrees cold side can be achieved with 0.326 W of power per Watt produced by the CPU. That's 26W Power supply required for an 80W heat output. Now compare that to the same cooling for a peltier.

Needs 4.563 W of Power per Watt of CPU heat. That's how inefficient they are. For the same deltaT, you'd need 365W for the same 80W heat load.

I'd say take these with a grain of salt, but it's still mighty impressive.

And yes they probably will be expensive, but the prices will fall, and when they do.......

Oh yeah, I'm sure a simple watercooling rig could keep the hot side at 50 degrees using a couple of papst fans at 7V.

Think about it, subzero and almost silent to boot.
