<P>PROBLEM TO BE SOLVED: To make a heat conductive substrate practicable as a control circuit board constituting an inverter device, to attain both cooling and insulating properties of a heat generating electric component mounted on the control circuit board, and to make the inverter device compact and lightweight, low-cost, and less in assembly variance and assembly man-hour. <P>SOLUTION: An inverter integrated type electric motor-driven compressor includes a thermal conductive substrate comprising a substrate body 41 made of an insulator and a heat conductive through member 42 made of a good heat conductor charged penetrating in a thickness direction of the substrate body 41 as a control circuit board (lower substrate 25) constituting the inverter device. A heat generating electric component 39 is installed in a heat conductive state on one surface of the control circuit board 25, the other surface is opposed to a plane part 31 for heat dissipation across a heat dissipation space 34, and a heat conductive filling member 36 which is flexible and has electric insulation and heat conductivity is charged in the heat dissipation space 34. The conductive filling member is flowable in the beginning, and cured after being charged in the heat dissipation space 34 to become an elastic body. <P>COPYRIGHT: (C)2013,JPO&INPIT |
