Abstract
A radiation part, a refrigerant tank having heating elements mounted thereon, and an inverter case are bonded together by welding or brazing. A cooling fan is provided at the back surface of the radiation part. IGBT modules are fastened to a side surface of the refrigerant tank and further fastened together to the inverter case together. A press worked thin plate materials are bonded together to the refrigerant tank by brazing. The IGBT modules, which are heating elements, are mounted to the inverter case by bolts through the component materials of the refrigerant tank. According to this invention, as these components can be fixed in a very simple construction without using any seat cock, the manufacturing cost thereof can be reduced.
