Abstract:
A power conversion device according to an embodiment comprises a semiconductor element, an air receiver, an air guide, an airflow straightener, and a flange. Assuming that the assumed travel direction of a vehicle is a first direction, the direction of gravity is a second direction, and the direction perpendicular to the first direction and the second direction is a third direction, the air guide is disposed so as to face the air receiver in the third direction, and, among both ends thereof in the first direction, the end closer to the center of the air receiver is defined as a first end and the end on the opposite side from the first end is defined as a second end. The airflow straightener extends toward the opposite side from the second end along the first direction from the first end of the air guide. The flange extends toward the opposite side from the air receiver side from the second end of the air guide.
