Mechanical heat transfer device

摘要

A unidirectional heat transfer device for use between an electronic assembly on an aircraft and the skin and/or pod on the aircraft. The device includes a thermal decoupler mechanism which operates to disengage a retractable interface heat transfer surface when the skin on the aircraft reaches a predetermined elevated temperature caused by the high speed of the aircraft. In the decoupled mode, the heat from the electronic equipment passes to a phase change material heat absorber to provide a limited capability cooling function during extended high speed aircraft operation.
