An object of the present invention is to provide a cooling apparatus using a boiling and condensing refrigerant which can be economically manufactured. Another object is to improve reliability of soldering. A refrigerant tank, on which hot objects to be cooled is mounted, is connected to a radiator for condensing the vaporized refrigerant through a coupler made of two plates bonded together by soldering. The coupler connecting the tank and the radiator can be made easily and economically even if it has a complex shape, because the coupler is composed of two stamped plates. To bond two plates together by soldering process, it is necessary to secure an air-tightness and a high reliability. Improved configurations of the coupler and ways of fastening the two plates effectively are provided in the present invention.
