TEC Chiller idea

[Johnny Bravo]

Didn't know if I should post this in this thread or the chiller section but here goes. Does anyone know of anyone trying this idea before and if it was in anyway sucessful?

two water blocks clamped together with a tec in between, so that the liquid flowing throught one block is cooled while the other block cools the tec? It prob has tho i coudn't find it in the forum

Any ideas?

yeah its been done but its redundant. Just use the tec to cool what you want and skip a step

Tec chilers are possible but havent been done properly. Lets say 16 350 watt tec's at 1/4 voltage on a long custom metal surface could work quite well though.

For chillers, phase change works better. TECs are best used for direct die cooling IMO.

You think that because up till now, no ones done a chiller well. The design im working on is 8" long, 1/2" thick, and 4" across, easily slimlined everywere, and for another 1/2" you can watercool the hotsides instead of air and then u just use a csp-mag and a bip3.

The problem there is having to cool 16 tecs and the fact that they would probably pull more power than a phase unit with results that are probably on par at best

At best, you'll still have just 1/2 the COP of a comparable phase change unit, and probably less capacity. By the time you add in the DC supplies and watercooling, you'll have no real size advantage. What does that get you, aside from the fact that its all solid state (except the pump)?

You guys should look at cathar's chiller project on OCAU, I think it has merit but I also thing that doing it direct die is the better plan.

It uses 2x TECs at low voltage to get slightly below ambient temps.

Oh the psu's from radioshack arent taht big, a cd drive at the most size wise. It would be posisble to fit a tec chiller in much less area, and not much more than a normal water systems, but much less than a chillre.

Thats true. Powersupplies come in better shapes then compressors. THose stupid domes are impossible to fit in most cases.

Yeah thats pretty much what we're talking about. Even at low voltage you're way below phase change effciency though, which is why DD makes so much sense (IMO).

See, if you look at most laws of physics. You can't create matter, you can't remove matter, and energy is never gotten rid of. Heat is energy, every form of cooling can hit the perfect cooling point. The level of coldness may not be the same for all, but the efficiency can. Its simply that no one has built a tec chiller that is really good at. Really good as in, can match or beat a single stage chiller.

Cant beat TECs for size or silence either. Its all a trade off.

Yup. I plan on creating mine once I get some more cash.

I modded my bigwater to incorporate a 110W tec and my temps are GREAT! not below ambient. But still great. And thats jus one air cooled 110W tec sittin in a res of water.
