Abstract

PURPOSE:To seal an electric component with a thermal conductive case and to eliminate the regulation of contact of a cooling plate to the thermal conductive case by holding both front and rear surfaces of a circuit board with cooling plates therebetween, and dissipating heat through the circuit board. CONSTITUTION:A circuit board 1 places electric components 2 on both side surfaces. Cooling plates 3 are so secured that contact surfaces are brought into close contact with the front and rear surfaces of the circuit board 1, a water supply port 4 and a drain port 5 are attached to the cooling plate 3, and connected to cooling water passage in the plate. The electric components 2 are connected by the inner pattern of the circuit board 1 to each other to form a circuit, heat generated at the time of operation of the circuit is dissipated from the surface of the circuit board in contact therewith to be dissipated to cooling water through the cooling plates 3.
