A Thermoelectric Cooler (TEC) is made of 2 contact materials. Passing current through it causes one side to warm up and the other side to cool. It is called the Peltier Effect. This TEC is made of a semiconductor : Bismuth Telluride. It has PN junctions. It has 127 such units all connected. They are sandwiched between two ceramic plates.

Impressive, did you place multiple TECs in a thermal series or just a single?

@BigBananaMan It is a single on a block of aluminum. There is arctic silver between the TEC and aluminum.
