Abstract
A hollow evaporator is disposed in contact with the upper surface of the CPU. Heat from the CPU is absorbed by the evaporation of the refrigerant. The vaporized refrigerant ascends through the vapor flow channel by convection, flows into a condenser located above the evaporator, and radiates heat to be liquefied. The liquefied refrigerant flows down by its own weight through the liquid flow channel and returns to the evaporator. This circulation is repeated in this manner.
