  • Patent number: 7796384
    Abstract: In a system for housing electronics cards, methods and systems for cooling the electronics cards are presented. Each electronics card preferably contains heat-producing electronics and a heat sink, and is preferably placed within a card guide of the chassis and secured into position with a clamping device. At least one of the heat sink, the card guide, the clamping device, and a cold wall of the chassis are used to facilitate the conduction cooling of the heat-producing electronics. Furthermore, a clamping device may rigidly secure a card into position, thus reducing the impact of vibrations (including shock) on the card. Additionally, an air flow further cools the electronics cards, the card guides, and/or the cold wall.

  • Patent number: 7773378
    Abstract: A heat-dissipating structure for the expansion board architecture is provided. A fixing element disposed on the heat-absorbing substrate fixes the motherboard and the first expansion board. The heat-generating elements on the motherboard or the first expansion board are directly in touch with the heat-absorbing surface of the heat-absorbing substrate to absorb their heat. The heat-dissipating board extended from the side of the heat-absorbing substrate then dissipates the heat absorbed by the heat-absorbing substrate. The structure thus solves the problems that existing heat-dissipating structures occupy larger space and therefore cannot be effectively used in an expansion board architecture to dissipate heat produced by the heat-generating elements between the motherboard and the expansion board and that it is likely to have assembly tolerance. Using the structure can reduce the space and the assembly tolerance, but effectively enhance heat dissipation in the expansion board architecture.
