COOLING STRUCTURE FOR VEHICLE POWER SOURCE UNIT
First Claim
1. A cooling structure for a vehicle power source unit comprising:
- a power source unit constituted of a power storage device and an electrical component disposed on a top of the power storage device and including at least an inverter, the power source unit being disposed under a floor of a luggage room provided in a vehicle; and
a cooling path formed in the power source unit to cool the power storage device and the electrical component using cooling wind, whereinthe electrical component includes an electrical component case for accommodating the inverter, and a heat sink unit includes a heat radiating plate having a plurality of heat radiating fins,the heat sink unit is attached to the electrical component case on a side of the electrical component case opposite to a side with the power storage device, andthe cooling path includes a first cooling path for cooling the power storage device using the cooling wind, and a second cooling path for cooling the heat sink unit using the cooling wind passed through the first cooling path.

Abstract
An electrical component disposed on the top of battery modules includes an electrical component case for accommodating an inverter and a DC/DC converter, and heat sink units attached to the electrical component case on the side of the electrical component case opposite to the side with the battery modules, and constituted of a heat radiating plate having a plurality of radiating fins. In addition, a cooling path has a first cooling path for cooling the battery modules using cooling wind, and a second cooling path for cooling the heat sink units using the cooling wind having passed through the first cooling path. With this arrangement, there is provided a cooling structure for a vehicle power source unit capable of cooling the battery and the electrical component including the inverter with a compact configuration.
