Document Type and Number:
WIPO Patent Application WO/2010/055761
Kind Code:
A1
Abstract:
An electrical part arranged on the top of a battery module (24) includes: an electrical part case (33) containing an inverter (34) and a DC/DC converter (35); and heat sink units (37, 38) which are formed by a heat dissipation plate (40) having a plurality of heat dissipation fins (39) and mounted on the electrical part case (33) on the reverse side of the battery module (24) with respect to the electrical part case (33). A cooling path includes: a first cooling path (50) for cooling the battery module (24) by a cooling wind; and a second cooling path (51) for cooling the heat sink units (37, 38) by the cooling wind which has passed through the first cooling path (50). Thus, provided is a cooling structure for a vehicle power source unit which can cool the electrical part including the battery and the inverter with a simple configuration.
