3x245w Tec Chiller w pwm controller 24/7

I guess I'll post a few pictures of a build I've just completed. The chiller itself is designed to run off a 24-27v power supply @ ~15 amps. That puts the chiller at ~400watts max power consumption. According to the charts the qmax @ 15 amps should be ~200watts each on these tecs for a total of 600 watts qmax.

The chiller is designed to go sub ambient but not sub 0ºc for 24/7 use on an uninsulated board. It is also designed to fit into a triple 5 1/4" bay and requires a 5volt supply from the computer for the controller.

Using the controller, the chiller should be pretty efficient at normal 24/7 computer use because the tecs will be off or at 50% duty cycle most of the time.

Anyway pics, I'll post some results after I finish testing this thing.

Sweet. Are you going to sell it or just for personal use? How well will do think it will cool? What size rad will you need to cool the hot side of the TEC's?

I just built it for fun so its really not spoken for "so to speak". I already have a tec chiller in my 24/7 rig.

Good question. I confirmed about 20ºc dt water to water on a I7 920@ 4.2ghz HT On @ 1.34v in an earlier test on the chiller itself running the tecs @ ~8volts (Note: They are only running at about 50% of the rated vmax for efficiency)

I think you are probably more qualified to answer that question. I can tell you that the tecs pull about 400-450w at the wall (I think about 50-75w of that is just the power supply) plus your cpu load, so maybe total load to cool would be ~ 650watts

What do you think it would take to cool that heat load?

i would so buy a small chiller package like that. just bolt it into main rig and go. flick it on on really really hot days in my appartment.

Nice design, very clever, makes for an easy placement. :)
Needs a metallic faceplate, though. :p:

That is frigging awesome. Can you make it run off a PSU? I would say a dual rad would be enough and a triple if you wanted to go really slow fans.

Looking very nice, but yeah as mentioned above a different faceplate would be l33t

good stuff

installed pics ?

awesome, pics with a running rig ?

I'm still looking for a solution for a good 24v-27v psu that can fit into a case.. Any suggestions?

I'll try to get a test computer up and running in the next couple days.

Do you have any pic's of the internals of that block?

nothing in this forum for AGES then "bam"

It takes people that have a passion for it, like yourself or mindchill, to bring it back to life.

yep.. It sucks to post stuff to a dead forum, but now that your back building, It motivates me..

Any updates on this, curious to see results.

single bay version,increase effiency % to like 250w usage for 600w load.Drilled holes for face plate attachment.

troll!!

He truly believes that you are handicapping all the results, you know, to sell a better model later.
He's clearly the next rocket scientist around here that knows how to make all that happen, thus the finger snapping.
