Abstract:
1. A system for securing and cooling electronics cards in a chassis, the system comprising: an electronics card containing: (i) heat-producing electronics, and (ii) a heat sink comprising edge and a face, wherein the heat-producing electronics are coupled to the face to conduct heat away from the heat-producing electronics; the chassis comprising a vent and enclosing a card guide steering the placement of the electronics card and dissipating heat from the electronics card; and a clamping device securing the edge of the heat sink to the card guide whereby (i) the edge of the heat sink is coupled with the card guide, thereby dissipating heat from the heat sink to the card guide, (ii) the heat sink is coupled to the clamping device and the clamping device is coupled to the card guide, thereby further dissipating heat from the edge of the heat sink to the card guide via the clamping device, and (iii) the edge of the heat sink is rigidly secured to the card guide, thereby reducing the effects of vibrations; wherein air flows through the vent and over the face of the heat sink electronics card to further cool the heat-producing electronics coupled to the face of the heat sink.
