So I'm looking at the TEC spec sheet you linked above:

But all that aside, lets say you ARE moving 125W through each TEC by supplying 28V/15A power. And in order to do so, each TEC will receive 420W electrically. So each TEC needs to dissipate 545W - and there are 4 of them, so now 2180W need to be dissipated from the hot side. A hot side that you're holding at 5C somehow... which will likely be require some other massive power consumption unless you're using an evaporative method of some sort?

I'm curious to see how this all pans out to say the least. Hope you run things at night when hydro is cheap!

Yes , dean.

Kartner , your numbers are correct.

I was looking at sinking 80-100 watts per pelt....really depends on what rig I put in.

....and 5C hotside is WORST case scenario.That's open loop watercooling......I want to hook it up to one of two glycol chiller systems I have access to.

If I can get onto the good glycol system , we're talking -7C pelt hotside !! ( 5 million btu/hr glycol system)

Hoe hoe hoe.



edit : "commentary"

This project is many years past being reasonable .

The tank alone is worth 10,000$ ..... Cost is no object anymore , I don't care what it takes , I want it to effing work the way I envisioned it 10 years ago !

hehe

It's not a computer you run all the time....It's a spectacle/tech demonstrator . I'm after sponsorship for every bit this time , I suspect by the time it runs , it'll be a 25,000$ rig , and it's not worth it.

Cool all the same.





The electricity and glycol systems are hopefully being provided by my employer.

I have an update.

-----

-I have located copper bar suppliers , I'm looking at 3 feet of 2"x3" c110 copper , waiting on some quotes.

-The frame is underway , but I'm holding off on some stuff till I have "parts-in-hand" .

-I have located a 32v/60 amp adjustable PSU .Hopefully I can buy/borrow it.

-I have also located a commercial phase change/glycol HX.......We'll see what transpires with this.

Here's the bad news :

It's still ski season and I'm gone......
