Problems solved by technology
However, this heat dissipation structure utilizes heat pipes for heat conduction, so the cost of components is relatively high. In addition, it is difficult to thermally couple the two ends of the heat pipes in an ideal state. State maintained at both ends of the heat pipe
The heat pipe can efficiently conduct heat, but the thermal coupling between the heating element and the heat dissipation part is not ideal. If thermal resistance is formed, the heat dissipation of the heating element cannot be efficiently performed

Abstract
In order to release thermal energy, of a heat-generating element mounted on a vehicle, to the outside of an outer case efficiently over a long period of time while simplifying assembly structure, thiselectrical equipment battery is provided with a thermally conductive space (10) between a circuit board (5) on which a heat-generating element is mounted and a metallic heat-dissipation plate part (8A) provided to an outer case (6). The space is filled with an electrically-insulative thermally-conducive gel (12) so that thermal energy of the heat-generating element (2) is released to the outsidethrough the heat-dissipation plate part (8A) in the outer case (6). Furthermore, the heat-dissipation plate part (8A) has provided therein an outflow-blocking partition (14) outside the thermally conductive space (10) for preventing outflow of the electrically-insulative thermally-conducive gel (12) in the thermally conductive space (10).
Description
technical field [0001] The present invention mainly relates to a battery for an electronic device for a vehicle that is connected in parallel to a lead battery that supplies electric power to an electronic device mounted on a vehicle. Background technique [0002] A lead battery for supplying electric power to an electronic device is mounted on the vehicle as a battery for the electronic device. Lead batteries supply power to all electronic equipment of the vehicle, and also to all components required to drive the vehicle, such as starters, engine control circuits, electric motors for electric power steering, automatic control, braking, steering, etc. The remote control unit supplies power. Furthermore, in order to improve fuel efficiency, vehicles in recent years have adopted a method of charging lead-acid batteries using regenerative electric power during idling stop and deceleration. [0003] Lead batteries continue to supply power to some electronic equipment component...
