Heat dissipater, especially for an active electronic box of a satellite or other space vehicle, comprises an L-shaped metal-encapsulated pyrolytic graphite plate fixed to the box and to a radiator

摘要

An electronic box heat dissipater (11), comprising an L-shaped plate of metal-encapsulated pyrolytic graphite fixed to the box (10) and to a radiator (13), is new. A heat dissipater (11), for an active electronic box (10), comprises an L-shaped aluminum-encapsulated pyrolytic graphite plate having a long arm (20) for fixing to a flat surface of the box and a short arm (21) for fixing to a radiator (13). An Independent claim is also included for an active electronic box (10) equipped with the a heat dissipater (11) as described above and consisting of a thermally conductive material (preferably pyrolytic graphite) encapsulated in a thermally conductive metal (preferably aluminum, copper, SiC, AlSiC or graphite).
