TEC Waterblock with heatpipes?

post #1 of 23
Thread Starter 
This idea just popped into my head when reading about a multiple-peltier water chiller. It uses 6 peltiers to chill the water.

My idea would utilize 4 peltiers and quite a few heatpipes. As an example, take the Thermaltake Big Typhoon. Eliminate the fins. Replace them with the "cold plate" on a TEC. This cold plate would hold 4 peltiers, say 172w apiece, all placed in a two-by-two square. We'd want to utilize 24V peltiers so they can be run at the efficient "half voltage."

The peltiers that I have in mind draw 5.5 amps apiece at 12 volts. The total current draw would be 22 amps. Their heat pumping capability is 40.9 watts apiece at 12 volts. This would make the entire system capable of efficiently pulling away 163.6 watts. This is just a rough estimate, because when running peltiers side-by-side like this, they become even more efficient than single pelts.

This would definately give you sub-zero temps. If you don't want to dive into the sub-zero area, you could probably severly undervolt the peltiers. I have successfully ran my 437w peltier at 5 volts and it still achieved sub-ambient temps, though only slightly. Full load was 29°C. This system could probably achieve the same temps (more than likely better) at lowered voltages.

If anyone is good with photoshop or CAD, try to design a pic of the thing so it can hopefully be shown to those who don't really understand what I'm getting at.

I guess the biggest question in the design is: Has anyone experimented with heatpipe coolers in sub-zero conditions? Stick your PC outside when it's 0°F out?

And would you be cooling the pelts with water still?

OK this sounds good but do the heatpipes run in the other direction, if you know what I mean- If I know what you mean?? mmm a little pic would be nice.

Yeah. Basically a waterblock/TEC on top of the heatpipes. That way the CPU is pumping heat to the heatpipes, which pump the heat to the peltiers. Here's a crappy PAINT drawing. I really need someone with photoshop or CAD to fix this...

(Pinhead-227 I am joining forces with you and got the 437 watt TEC ordered from frozen cpu, might need some help mate)
For this design it would be more efficient to have more than one peltier to further spread the heat over a larger area. With a single large peltier, direct-die cooling is the most efficient. But I'm constantly trying to find a way to make a good TEC waterblock.

That just might work but will the heat pipes transfer the cold down towards the cpu or do they only run in one direction.......

heatpipes run in one direction....due to design, the cooler liquid stays at the bottom, and is wicked up with heat....i honestly dont; see that working....

Than how does a regular heatsink work? The CPU is hotter than the fins on the top of the heatsink... It hasen't changed here. The CPU is still hotter than the "cold plate" where the fins would normally be...

Edit: The easiest way to test this is for someone with a heatpipe cooler to put it in a deep-freeze or outside when it's freezing out. That'll prove or disprove it.

I understand this now, this should work, you are just trying to make the HSF get rid of the CPU heat better by using a pelt instead of a fan \\fins. Am I correct? A small step from direct-die and maybe a very easy application with-out the massive condensation problems with direct-die. This will need some work, I have a 226 watt pelt left over now so I might try and rig something up with a modded 4400 HSF.
