Patent abstract
The present invention is directed to a method of constructing a semiconductor chip cooling device consists of multiple fans and heat sinks to provide redundant cooling capability. Heat coming from a semiconductor chip is first distributed to several heat sinks using multiple heat pipes. The heat sinks are placed around the fan outlet such that air is pulled in near the center of the fan and then pushed to across the heat sinks. Multiple fans and heat sinks are stacked up to form a complete cooling device. An external control circuitry is used to monitor and control the fans. In case of one fan fails, the other fans will be speeded up to make up the lost of air flow.
