Document Type and Number:
Japanese Patent JP5868047
Kind Code:
B2
Abstract:
Provided is an in-vehicle power source device wherein it is possible to improve safety and ameliorate heat dissipation. In an in-vehicle power source device (100), the low heat-dissipation surface (137a) of a DC-DC converter (130) is disposed adjacent to the side surface (141c) of a low-voltage battery (140) so as to face said side surface (141c). Meanwhile, the high heat-dissipation surface (133h) of the DC-DC converter (130) is disposed on the opposite direction of the low-voltage battery (140). As a consequence, the amount of heat generated at a large-size heat-generating element or a power transistor within the DC-DC converter is preferentially transferred to the high heat-dissipation surface on which a heat sink (133f) is disposed, thereby inhibiting the heat transfer to the battery side (in the second plate thickness direction). Thus, the low-voltage battery (140) will hardly receive any heat from the DC-DC converter (130) even when the DC-DC converter (130) is driven, and the risk of causing a temperature increase is reduced.
