Next it was time to fit it onto a phase change system! I made
a pair of these for Dual VGA cooling and connected them to a dormant chipset
cooling system which I have not been using for a long time. It was a dual capillary
tube feeder system.

I charged up the unit and off it went! I used refrigerant R22
and rather big capillary tubes to try to aim for -20C on the copper coils.

Frosting action!

In the end I reached -15C on the copper coils and around 10C
on the whole plate. Good enough for my use!

The whole setup after insulation:
