Phase-Change setup or Water chiller setup?

[Dissolved]

ok, Its summer, i need something to do, and ive been thinking..

I wanted to build a Phase change setup about 4months ago, but i didnt know exactly what i wanted to.. After thinking about alot of stuff im bound between 2 things..
1. a phase-change unit (Direct Die cooling) OR
2. a water chiller.. (same unit but cooling a large res to cycle through a water setup)

i have access to r22, and a r4xx refrigerent. im pretty much set on r22 ATM, since i hear its really good to use.

What im not to sure about doing is if i wanted to make a chiller or phase change setup, so thats mainly what i need more input on.

*Chiller:
Pos- Can make a Cpu/NB/gpu water cycle useing only one pump.
neg- Would cost more, as id need to buy or make blocks for each place i wanted to cool.

*Phase-change unit:
pos- Would cool Alot better since its direct cool cooling
neg- One unit could only cool one heat source. (dual blocks could be used, but is exteremely hard to get a unit to work as ive been told)

-/-/- With that in mind, a Weird idea hit me last week.. Now this might be dumb or allready thought of, either way its my idea.
if i made a Phase change unit just like anyone elses, But made the evap/cpu block so that water could run through it to other sources ie. NB/GPU to cool them?

So the phase change unit would act like a water chiller, and a direct die cooler in one block. Might be hard to do, and i dunno if it would be possible or even work. but i just wanted to get some feedback on all these thoughts..
Thanks

Id have said chiller was easyer, as then your just watercooling, plus you can modd a fridge and you dont have to make a complicated evaporator..

But a direct die will giver lower temps.

If your confident you can do it (and want a challenge) then id make a direct die cooler.

Take a look at bowmans stuff on www.phase-change.com im sure he will post later with some advice.

well could be done but block for one wouldnt hit -40 temps because of the heat load between the liquid and the cpu hitting it at once.and the block would have to be pretty large to be effective.

now combining a cpu evap and a secondary chiller being cooled by the return wont work,,,i tried. not enough return to cool much of anything.i had to add a second cap tube to suppement the refrigerant return in the chiller to handle the load.this works but extremely hard to get working properly.

the best bet is a chiller unit.they are so universal.and it will grow with your needs.easy to build.easy to buy waterblocks.not hard at all.

i think ima try the chiller. i can always add a Direct die system later on when i get the cash.

im thinking of a 1/2HP r22 unit.
with some regular waterblocks. im not sure if i want to use pelts or not. probly on my GPU, but i dont think ill gain much on the cpu. to much pain to have to buy a psu and stuff.

What im thinking is, instead of useing all 1/2" tubeing, is haveing the cpu intake 1/2" tubeing from the res, then on the outlet of the cpu block, Split the 1/2" line into 2x 3/8" tubeing one line to go into the NB block and one for the Gpu block.

1/2" tubeing on 3 blocks will take up alot of room, and will be a lil harder to place. and id think the NB and gpu would be cooler if the both got water from the cpu at the same time instead of in a looped system gaining heat from the block in front of it.

So my loop would be like so:
Compressor unit(chiller)>Res>Pump>1/2" tubeing>Cpu Block>1/2" tubeing>Y spliter 1/2~3/8"(might be hard to do)>1 line into the NB Block, 1 line into the Gpu Block> both lines go back into res...

i hope this makes sense. But i think ill get that swiftech GPU block with the 80mm pelt so that might help the temps.

What do you guys think?

Thats exactly how I run/ran my system, but if your running a pelt on the GPU you might need more flow through that block.
Best way will be to set the system up and do some quick flow measures before you install it to work out the best method.

well i was thinking that.. i thought id use a powerfull pump. maybe 400gph about. i just gotta find one that could handle -20c and below temps..
a problem i fear with looking for parts is that such low temps will mess up expoxy and rubber sealing. so the blocks will need to be sealed by brazeing and have metal barbs with a good seal.

i wanted to get swiftech blocks, but they use Plastic barbs and i dunno how good those would be if given -20~-35c temps..

And also, wouldnt i need to condenstate proof all the tubeing in the case?
this is something also im worrying about bec that will take more room up in my case and im not to sure how i wanna have them enter the case. i want to make the chiller as small as possible and portable if i have to move it.

OK first stop worrying about your pump.pick up a pump that will handle your flow requirements.400gph should be just fine.then place the pump in the center of the chiller tank.you dont want to use a inline setup for a chiller.now for coolant use windshield washer solvent.just look around and you can find some that will handle -60c temps.and it will not thicken up.i use washer fluid.it works great.and i havent had any probelms with my pumps.washer fluid has to be safe for plastic and paint.so it wont hurt a pump.
now you will have to insulate the lines.but thats easy.easiest way to enter the case is though the back of the pc.this keeps the hoses inside the case to a min.most likely the return lines wont have to be insulated because by the time the coolant has absorbed the cpu,gpu,chipset, it has warmed up enough to not cause condensation.

well i just dont know how easy it would be to proof the lines in the case, seeing theyd have to bend Alot to go from the cpu/nb/gpu that might be a problem. So i think ill just try to make the system and only cool the CPU till i figure this out more.

id like some kind of hose system that i can attach to the case or something so i can pull the blocks in/off with having to take them off the barbs and such. So drilling a whole in the case and feeding the hose through wouldnt allow me to remove it if i needed to.

pump wise, ill just buy whetaver i can get that will do about 400gph with a good warranty. so that'll be aok.

so i know what i want, but i just gotta get the exact parts figure out what res i wanna use, and see if i can make a nice setup. and last of all See if the parents will help me fun my project. (im sure theyd like a compressor noise over a delta fan at 3am. :)
