But the other surface still has to be cooled!
Why would you male your life more complicated that it already is? For
Peltier elements you have to have a separate energy source, additional
cooling fan(s) etc.
On the equipment that I'm maintaining, there is a sort of refrigerator
that keeps the internal temperature at approx 8 C. It uses 8 Peltier
elements of approx 50x50mm max thermal power per element is 79W. The
elements are mounted one side flat to the Al compartment that has to
be kept cool, and the other side to the Al black anodized heatsink of
approx 1sqft onto which two 120mm fans are forcing the air.
Does this look reasonable?
