Abstract
According to the present invention, a cooling apparatus using boiling and condensing refrigerant, includes a fluid separating plate for separating a high-temperature fluid from a low-temperature fluid, a refrigerant tank disposed on the side of the high-temperature fluid from the fluid separating plate, a refrigerant sealed into the refrigerant tank, a pair of communication pipes, one end of which is communicated with the refrigerant tank hermetically, a condensing portion communicated with the other end of the communication pipes and disposed on the side of the low-temperature fluid from the fluid separating plate, and a heat insulating material as a high-temperature portion-side heat insulating material coated on the outer periphery of the high-temperature-side communication pipe. In this way, it is possible to suppress a heat conduction from a high-temperature portion (high-temperature air) to the high-temperature-side communication pipe. As a result, it is possible to prevent the descending refrigerant which has been condensed and liquefied in the radiator from receiving heat from the high-temperature portion through the high-temperature-side communication pipe to receive an ascending force in the high-temperature-side communication pipe.
