ABSTRACT:
A unidirectional heat pipe (22) acting as a thermal diode or a heat switch, enables heat to be removed from electronic equipment (14) when temperatures outside of a missile envelope (12) are lower than those of the electronic equipment. When the temperature exterior to the missile envelope is greater than that of the electronic equipment, the heat therefrom is conducted to a package (16) containing phase change material which absorbs the heat from the electronic equipment, at which time the heat pipe acts as a thermal insulator. Heat is also removed from the PCM package by the heat pipe when exterior temperatures are lower than interior temperatures.
