Heat sink comprising synthetic diamond material

摘要

A heat sink comprising a heat spreader (2) made from synthetic diamond and having a front surface for mounting one or more components to be cooled like a laser disc (8) and a rear surface for direct fluid cooling (10). A plurality of ribs (4,7) is bonded to the rear surface of the heat spreader (2) to stiffen the heat spreader. Both the heat spreader and the plurality of ribs are formed of synthetic diamond material. The ribs (4,7) may be fixed to the heat spreader by braze bonds (6).
