Patent ID: 8873237

Claim:
A system for cooling a heat-generating device, the system comprising: a base, having a first side that is thermally coupled to the heat-generating device; a housing coupled to a second side of the base; a liquid channel formed between the base and the housing, wherein a heat transfer liquid may be circulated through the liquid channel to remove heat generated by the heat-generating device; and a heat pipe disposed within the liquid channel, wherein the heat pipe is thermally coupled to the second side of the base, has a first portion proximate to the heat-generating device and second portions extending beyond the heat-generating device to define low-temperature heat pipe regions, and includes a wick structure internal to the surface of the heat pipe for drawing liquid to a heat source adjacent to the heat-generating device through capillary attractors and includes a vapor chamber within the wick structure and central to the heat pipe for carrying heated vapor to cooler regions of the heat pipe via a pressure gradient, cooled fluid thereafter being returned to the region adjacent the heat generating device, the heat pipe being configured to increase the heat transfer surface area to which the heat transfer liquid is exposed.
