COOLING DEVICE, HEAT RECEPTION UNIT AND BOILING UNIT USED THEREIN, AND METHOD FOR MANUFACTURING SAME

摘要

In order to maintain strong cooling performance even when a heat-generating body generates a small amount of heat, a boiling unit of a heat reception unit in a phase change cooling device comprises a comb-like structural body and a porous layer provided at the base part between the fins of the comb-like structural body. By means of this boiling unit a liquid-phase refrigerant can be converted to a gas-phase refrigerant even when a liquid film of the liquid-phase refrigerant is forcefully made thin and the temperature difference between the gas-phase refrigerant and a heat-receiving surface is small.
