Please explain Freon Cooling

[TubsAlwaysWins]

Ok so someone please explain freon cooling to me. Isn't it the same as phase change? If I were to set up a freon/phase change cooler what order would the loop need to be in? (condenser>res>GPU>RAD... etc.)

yeah its how your AC works in your car.

freon cooling is phase change cooling

So if I was to go and find a old condenser unit what else would I need?

When the liquid freon flows (in its critical state) to the heat generating compontent in this case a CPU or GPU it evaporates quickly which inturn takes heat away from said component, it then travels back to the compressor before that it passes through a heatsink which cools it for ease of compression. It gets compressed back into a liquid and the whole cycle repeats.

So I would go res> pump > GPU > CPU > RAD > compressor   right?

Yeah pretty much although the CPU and GPU both need a loop

it can't be in series needs to parallel, I think

Blocks that can withstand very low temps and alot of insulation

That would be more difficult than you anticipate, Fridges only go on for a couple of minutes at a time so you'd need parts that were rated for 24/7 for the cooler to not break down constantly. What you'd need is some kind of industrial one.

 

You'd also need to be something of a Physics buff to be able to do this and if you're only just learning how one of these systems works, I doubt you'll be successful in your endeavours (at least in the near future).

If I was to keep it at like a degree above room temperature....

Because the freon has to evaporate to take the heat away when it passes over the CPU and evaporates you won't be able to run that to the GPU to get it to cool that. But as I said I'm not completely sure about that

For the physics side I don't know a ton, but I do have the internet and my dad to help me. He can usually figure stuff like that out

The cold freon will always be at excess of -40C and even if it would be 1 degree C water will still condense and we all know what water does to electronics..

Ok so basically I will be getting negative temps then

You can check out Linus' video above for a typical scenario and expected temps.  I would also advice you watch it to see what kind of prep is needed to do this safely, since jumping straight in without the right preparation will cause condensation all over the motherboard which will probably kill it.

Yeah. I would use some eraser stuff and neoprene

you need a fairly powerful condenser 
@Jumper118 knows some things I believe

Bit late but..

 

Not feasible.

 

You need to know how to get the gas level correct, oil correct, correct suction & discharge size and correct placement and size of u-traps.

 

Then you need a compressor capable of sustained load, suitable gas type (depending on target temp, crappy compressors like the one in Linus' video use R134a, cooler phase units will use gas like R507/R404a) and a condenser with enough capacity to dissipate the heat.

 

And then you also need a power solution.

 

I have 2 units, one is a little Danfos type LBP compressor which is around the 1/3hp mark and uses R404a. Tops out around -44c at evaporator without load. And with a quad core load at 1.55V it will go to around -30c. My other unit is a 3/4hp rotary style which is far more efficient as far as compressors go, and uses R407C and tops out around -59.5c. With quad core load at 1.55v it will do around -56.5c

Why?

the freon would be evaporated after touching the first heat generating component, and would not transfer more heat

you could pulse the cooling like fridges do based on cpu temps
