VEHICULAR POWER CONVERSION DEVICE

WIPO Patent Application WO/2014/203374

A1

This vehicular power conversion device is provided with a semiconductor that converts power. Said power conversion device is provided with: a plurality of coolers (210) that are aligned in the vehicle advancing direction and cool the semiconductor; a cooler cover (220), inside of which the plurality of coolers (210) are installed and which is provided with a ventilation opening serving as an intake port and exhaust port for travel-generated airflow; and an airflow guide plate (230) that is installed inside the cooler cover (220). A cavity serving as a passageway for the travel-generated airflow is provided to at least one of above, below, and to the side of the plurality of coolers (210) inside the cooler cover (220). The ventilation opening is at least disposed in the cavity in the vehicle advancing direction. The airflow guide plate (230) is disposed in the cavity and, when the travel-generated airflow flows from the ventilation opening into the cavity, changes the flow of the incoming travel-generated airflow such that said air flows in the direction of the coolers (210).
