ELECTRIC CIRCUIT DEVICE AND COOLING STRUCTURE THEREIN

摘要

PROBLEM TO BE SOLVED: To provide an electric circuit device and a cooling structure therein, capable of lowering the temperature of the whole electric circuit device with a simple structure. SOLUTION: In the electric circuit device wherein electronic parts 1 are mounted on a substrate 10, a sheet shaped electric insulating substance 4 with thermal conductivity is laid on the electronic parts, a bus bar 3 with thermal conductivity is provided on this sheet-shaped electric insulating substance. The both ends of this bus bar are characteristically fixed to the substrate in the electric circuit device. COPYRIGHT: (C)2006,JPO&NCIPI
