  • METHOD APPARATUS FOR COOLING SYSTEM HAVING AN S-SHAPED AIR FLOW PATH FOR USE IN A CHASSIS
    Publication number: 20090109619
    Abstract: A method and apparatus cooling a chassis. The apparatus includes a telecommunication shelf structure or chassis (102) having a top side (108), bottom side (110), front side (104) and back side (108). Slots that can support boards (112) are oriented between the top side and the bottom side. A first set of fans (126) pushes air flow through the slots from the front and bottom sides of the shelf structure to the top and back sides of the shelf structure, and a second set of fans (128) pulls air flow through the slots from the front and bottom sides of the shelf structure to the top and back of the shelf structure. The first and second set of fans form a fault tolerant and redundant fan configuration in the telecommunication shelf structure to achieve an S-shaped air flow through the telecommunication shelf structure.
