Patent ID: 7184265

Claim:
A cooling system for a portable computer comprising: a frame having a heat-source connecting unit contained within a first side and having a fan housing unit in a second side; a dissipating unit on one side of the fan housing unit of the frame that is configured to perform heat exchange; a dissipating fan within the fan housing unit configured to form an air stream that would pass through the dissipating unit from inside the fan housing unit; and a cooling unit coupled to the first side of the frame and configured to deliver heat from the heat-source connecting unit to the dissipating unit, wherein the cooling unit is a micro cooling unit configured to perform heat exchange using a cooling cycle caused by phase change, and wherein the micro cooling unit has an internal circulation loop that comprises, a liquid coolant moving block configured to return coolant to a beginning of a liquid phase transition block from an end of the liquid phase transition block, and an insulation block between the liquid phase transition block and liquid coolant moving block.
