Cooling system, heat-receiving portion to be used to it, boiling part, a method of manufacturing

摘要

even when the heating element is low heat value, to maintain a large cooling performance, boiling portion of the heat receiving portion of a phase change cooling system, a comb-shaped structure, between the fins of the comb-shaped structure It consisting provided at the bottom with a porous layer. Such boiling portion forcibly by thin liquid film of the liquid layer refrigerant, even a small temperature difference between the temperature and the heat receiving surface of the vapor-phase refrigerant, thereby the phase change of the liquid phase refrigerant into gas-phase refrigerant.
