Supercritical fluid CO2 cooling?

Recommended Posts

Posted · Original PosterOP

I've seen liquid nitrogen cooling and I've seen dry-ice (Solid CO2) used to cool things and I've seen liquid cooling with water and mineral oil etc.

But what about Supercritical Fluid CO2 cooling? Would that work?

I dont think supercritical CO2 is going to be any good at cooling


I spent $2500 on building my PC and all i do with it is play MTGA & watch anime at 720p...

Builds:

The Toaster Project! Northern Bee! The Cassette Deck!

 

The original LAN PC build log! (Old, dead and replaced by The Toaster Project & 5.0)

"Here is some advice that might have gotten lost somewhere along the way in your life. 

 

#1. Treat others as you would like to be treated.

#2. It's best to keep your mouth shut; and appear to be stupid, rather than open it and remove all doubt.

#3. There is nothing "wrong" with being wrong. Learning from a mistake can be more valuable than not making one in the first place.

In order to maintain the supercritical fluid state of carbon dioxide, it needs to be kept above its critical pressure (72.9 atm, 7.39 MPa, 1,071 psi, 73.9 bar) and critical temperature (304.25 K, 31.10 °C, 87.98 °F).

This means you need an air-tight high-pressure thermally-conductive container that cannot cool down below room temperature.

So no.
