    摘要： Measures are provided to prevent temperature rise caused by that heat generated from power elements, which is radiated inside a housing.In a housing comprising a radiating section and a cooling fan, a guide is provided on a part of the housing to be made longer a predetermined value than the radiating section. When the cooling fan performs forced cooling through the guide, gases heated by a substrate that generates much heat are prevented from flowing onto a substrate that generates comparatively less heat, to heat the substrate that generates comparatively less heat. Therefore, for example, the substrate that generates much heat is arranged in a position nearer to the cooling fan than the substrate that generates comparatively less heat. Alternatively, the substrate that generates much heat is arranged in a position nearer to the intake face than the substrate that generates comparatively less heat. By providing the guide on the housing, an existing fan can radiate heat from the substrate that generates much heat, the substrate that generates comparatively less heat, etc., thereby enabling reduction in temperature rise.

    摘要： In order to bring a moduled power converter into less size and cost in the case of a structure having a lead-insert-case, an insulated metal circuit board and a printed circuit board, a difficulty was encountered in thinning a wiring width and an increase in pad area for each metal wire has interfered with a reduction in its size and cost.In the present invention to cope with it, a power converter is constructed by using a semiconductor module having such a structure that a metal base and lead frames are adhered to each other in a state in which an insulating adhesive sheet is interposed therebetween, a resin-molded outer package is adhered to the metal base with an adhesive or the like, and a resin sealing agent is charged into the resin-molded outer package to thereby integrally seal the resin-molded outer package and circuit parts such as semiconductor elements implemented therein, whereby a reduction in size and cost thereof is realized.
