More Information
Summary:In order to maintain a high cooling capability even in a case where a heating element has a lower calorific value, a boiling section of a heat receiving section in a phase change cooling apparatus includes a comb-shaped structure and a porous layer provided on a bottom portion of the comb-shaped structure between fins of the comb-shaped structure. With such a boiling section, a liquid film of a liquid phase refrigerant is forcedly made thinner. Thus, the liquid phase refrigerant is changed in phase into a gaseous phase refrigerant even in a case of a small difference between the temperature of the gaseous phase refrigerant and the temperature of the heat receiving surface.
