Tt water block to evaporator conversion

[tiborrr]

Today I converged a regulat Thermaltake water block (from 760i cooling unit - click! (http://www.thermaltake.com/product/Liguid/DIY/cl-w0121-03/cl-w0121-03.asp)) into a vapor phase change evaporator. I rebrazed all the joints that we're already factory brazed and attached stubs for easier installation of suction line & cap tube (or any other metering device). I decided to go with this block since it already had the complete retention mechanism, it was fairly thin, has a lot of cooling surface area and it's 100% made of copper. Plus they're dirt cheap too!

I'm missing a suction line and a small condenser, otherwise I would already show a complete unit :yepp:

Nice :D

Do some tests to see how much load it can handle! I'm thinking it won't be much tho' ...

[MeltedDuron]

Can we please place $1 USD bets on load it can hold? Loving your work dude

[trance565]

nice, i guess your going to put the cap tube thru one of the biggerpipes? or maybe drill 2 holes for 2 cap tubes?

[tiborrr]

Thanks Jack, MeltedDuron! :up:
About load - hehe, we will see, I will hook it up on an autocascade, I'm just out of stainless stell flex tubing and missing a condenser. I'll open an auto-C thread aswell, I just have take some photographs of the system before doing that.

@trance565: Thank you! Yes, the copper stubbs (bigger pipes) are brazed there to make cap tubing brazing easier. Single cap tube feed. It could also be two, three or more cap tube feed, even an TXV or AEV (CPEV) isn't out of the question if you're building an conventional single evaporation system (not auto-C, but regular SS).

This should be very interesting. I don't think it has enough surface area given what it was originally designed for, but that is definitely very creative of you.

edit: actually, should be quite interesting with those micro-channels they've milled into the surface. I read some research on evap design for cooling electronics(CCDs were their targets) and they settled on a similar evaporator design.

I think the Heatkiller 3.0 CU version is THE block to try this with...

i tried this with an old swiftech 5002 block and got pinhole leaks around the base :(

i was really hoping it would work though.

i think most people think its the evap that cools the cpu --
its not the gas cools the cpu the evap is just the vessle to atach to the cpu
great idea tiborrr
i have some TT water blocks i thought about convertion to gpu evaps

and 2 gpu blocks

i dou have the tt cpu water block some where the big chunky one i think i made it in to a ln2 pot :)
