Hi guys. A while ago I started making my own chiller. Just today I finished it but I wont be able to put refrigerant in for another week or so. My aim was to chill my cpu (-20 loaded would be nice) and gfx card
The evap i am gonna make is based on dabit's latest chiller where he used three coils (3.5m each) and a distributor to distribute the refrigerant evenly. As a distributor I used three pieces of cap tube of 0.048" and 30 cm length. These go to a small piece of 1/4 tubing. The three coils go to a reservoir of 22cm height and around 9-10cm diameter.
Some photos of the evap coils

The condenser is 23*25 cm and is made of 3/8 tubing.

The evap's outer shell is made of pvc and the caps from thick plastic

Ready. I just need to braze the cap tube (still thinking about its length) and a shrader valve on the compressor.
