Electronics cooling technique for spacecraft modules

摘要

A spacecraft avionics module in which integrated circuit chip packages or chips are mounted in direct contact with the surface of a radiator panel, to enhance dissipation of heat from the integrated circuit and to allow electronics to be packed more densely while still dissipating sufficient heat to allow the electronics to operate at a desirable temperature. Conduction of heat from the electronics to the radiator panel is further enhanced by the use of a thermally conductive adhesive disposed between the integrated circuit chip packages or chips and the radiator panel, which may include heatpipes for more uniform heat distribution across the panel.
