PURPOSE:To enable to fit the control circuit device in an engine room by a method wherein an accommodating portion of the control circuit for the automobile and an outside portion of a car body are connected by a heat pipe to cool the circuit. CONSTITUTION:The control circuit is closed in the accommodating portion 8 fitted at a side wall portion of a tire house 4. A heat receiving portion 9a of a heat pipe 9 is connected to the accomodating portion 8. The heat pipe 9 is penetrated through the side wall portion of the tire house 4 and is conducted to an outside portion of an engine room and a heat radiating portion 9b thereof is earthed to a low- temperature side of a fender 5 exposed to open air. Therefore, heat in the accomodating portion 8 fitted in the engine room is dissipated to the outside thereof by the heat pipe 9, accordingly, temperatures of electronic elements in the control circuit and the like may be kept in a relatively low temperature. |
