On a thin piece of copper plate, I cut out the plate with a
pair of shearers.
As seen above, I also drilled out the mounting holes to mount
the chiller onto the card.
Next, I brazed on a thin roll of 3/16" copper pipes onto
the plate. My first job ended up with me overheating the pipes and breaking
part of it.
So I did another one.
You see that the capillary tube runs into one end of the pipe
and the refrigreant flow exits through another end. For a more indepth on how
refrigeration phase change works and is built you can check out some guides
