Patent ID: 7913507

Claim:
A cooling system for cooling a heat generating component in electronic equipment, comprising: a heat receiver thermally connected to the heat generating component, the heat receiver including: a heat receiver base contacting the heat generating component and having a substantially flat surface; a box; a gas flow space surrounded by the heat receiver base and box; a liquid refrigerant inlet through which a liquid refrigerant dribbles down along an internal surface of the heat receiver base on the side of the gas flow space; a liquid refrigerant spreader for spreading the liquid refrigerant thereacross to form a film, the spreader having a mesh portion with an opening for passing a vapor of the refrigerant and releasing the vapor into the gas flow space; a gas inlet through which a gas used for vaporizing the refrigerant is fed from a blower; and a gas outlet for venting, from the gas flow space, the gas containing the vapor released from the spreader; a closed refrigerant circulation path, including: the heat receiver; a refrigerant condenser; a refrigerant pump; and a refrigerant tank; and a closed gas circulation path, including: the heat receiver; the refrigerant condenser; and the blower.
