Determination of the thermal resistance of aluminum and copper heat sink in a thermoelectric pump

Abstract

Thermoelectric pump is a main unit in a thermoelectric cooling system. For effective performance of the Peltier module, the heat power generated at its hot side must be dissipated by a heat sink and a fan. The present paper discusses a method for calculation of the thermal resistance of aluminum and copper heat sinks with parallel plates. The two materials are compared with respect to the number and length of the fins.
