Abstract

A vehicular power conversion device is provided with a semiconductor that converts power. The power conversion device is provided with: coolers that are arranged in an array in a vehicle advancement direction and cool the semiconductor; and a cooler cover having the coolers located therein and provided with ventilation openings serving as an intake port and a discharge port for travel-generated airflow. A cavity serving as a passageway for the travel-generated airflow is provided in at least one of above, below, and to the side of the plurality of coolers inside the cooler cover. The ventilation openings are disposed in the vehicle advancement direction from the cavity. The airflow-receiving plate is located in the cavity and, when the travel-generated airflow flows from the ventilation opening into the cavity, changes the direction of the incoming travel-generated airflow to a direction toward the coolers.
