Abstract:
A system comprising:a device that generates heat during operation the device having a surface; a heat spreader thermally contacted to the surface, the heat spreader having a phase-change mechanism adapted to spread heat; and a heat conduit in thermal communication with the heat spreader to transfer heat from the heat spreader to another location in the system, wherein the heat spreader has a first housing, and the heat conduit has a second housing, each of the first and second housings defining an inner space in the corresponding heat spreader or heat conduit, the housings being connected to provide fluid communication between the inner spaces of the heat spreader and heat conduit, wherein the heat spreader has a first wick structure with fluid flow paths for liquid flow, and the heat conduit has a second wick structure with fluid flow paths for liquid flow, wherein the first and second wick structures are connected so that the fluid flow paths of the first wick structure are in communication with the fluid flow paths of the second wick structure.
