US Patent 7796384 Hybrid chassis cooling system

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.
