Air cooler with heatpipe at - 20C or below

post #1 of 9
Thread Starter 
Honestly I could not figure out whether to post this here or on air cooling forum. So I apologize in advance in case I'm wrong.

I'm planning a phase change cooling that involves indirect cooling freezer(indirect means cold air via fan, not evaporators running through the walls) and a pc inside.
This is not a puny little fridge, but an industrial fast freezer with 800 watt compressor with large condenser with forced airflow with little to no froasting.

Advantage of it is that I will be able to do sub zero temp without liquid cooling hassel.

One major problem I face is the air cooler. Most air coolers use heatpipes filled with liquid ranging from water to ethanol. I heard that most products have water inside them and will freeze when going sub zero. Does anybody know a way around this problem?

Yes, use a cooler without heat pipes.

All heat pipes use a water/ehtylene glycol mixture to create a boiling point right at the intended operating temperature of the chip.
Make sure the heatsink you choose doesn't have a vapor chamber or any heatpipes.

(or you could cut a heatpipe open, evaporate the liquid, and fill it with a liquid of your choosing under pressure and re-weld it. I've done this about 80 times and it's terribly tedious.)

I didn't even know they existed! Thanks. All I found are intel stock coolers or equivalent. Does anyone know a more "premium" no-heatpipe cooler?

I've used these in the past and they're better than stock. https://www.arctic.ac/uk_en/alpine-11-pro-rev-2.html

What about using a Hydro cooler?

Sadly none of these cooler are designed for 2011 socket. Yes, I might go with a hydro cooler with some antifreeze. I think swiftech hsve one of those AIO coolers with open-able reservoir.

Unless you set the boiling point of the fluid near the intended operating temperature of the CPU you'd still just have a copper tube, not a functional heat pipe, and if that fluid wasn't significantly water, it probably would not have the volumetric heat capacity or energy of evaporation to cool well, even if it made a functional heatpipe.

Ammonia is the only substance I can see being remotely practical.

There are some 1U server heatsinks that solid copper with skived fins, but "premium" heatsinks without heatpipes or vapor chambers went the way of the dodo about a decade ago. Even many of the high-end Intel stock coolers have vapor chambers.

A custom made heatsink milled from a block of copper, a standard liquid loop with a significant anti-freeze content, or converting the insides of that freezer into a phase unit you can directly attach, are likely your only options.

I don't see how you can run subzero without a vaccum or a fully insulated enviroment.

You have the cooling devices, all you need to do is fully insulated up your motherboard and doing a direct contact setup and run it with ice

At first it may seem scary and hard to do, insulating and running a pc at iced up situations. But once you do it you will realise that it is not that hard at all. (This is what I think cause I have tried running my pc with condensation due to peltier cooling)

You could get a LARGE block of copper. cross-cut fins in the top and drill holes in the bottom to mount it to your board from the bottom side. Should work if it's big enough to absorb the CPUs heat. I bet there is a couple of guys here that would be willing to make it for you.

EDIT: I never understood why a block has to limited by the size of the mounting holes when you can mount it from the underside.
