Has anyone ever tried hooking up a Phase change unit to a reservoir? Like this one on frozen cpu Reservoir (http://www.frozencpu.com/ex-res-06.html) Maybe change the top of the reservoir to copper or something and then hook up a unit to that? So then you get a chilled water type effect?

Problem with that is surface area. I mean the plastic that's used isn't going to be great when frozen, and would likely crack, but the main thing is you've got just that small evap working on the res, and the surface area of the res isn't that big either.
Best way is to change the evap into coil in coil, or coil in res, and run it that way.
I've got a small (TL4A) compressor I'm gonna make into a small chiller, and I'm just gonna make a pipe in pipe heat exchanger for it. The heat transfer isn't even going to be optimal that way, but far better than trying to get the heat through a tiny surface are like a DD evap.
Sorry, mate. It might bring water temps down a tiny bit but not very much.

Hehehe...you lost me with the coil in coil =/. Rather new to phase change. I know that the surface area is small. What if the reservoir was made from copper or something? The surface area is small, but if you let it sit there for awhile, wouldn't it cool down the entire thing?
