US 2021/0243922 A1 · COOLING SYSTEM FOR POWER CONVERSION DEVICE

Abstract

Provided is a cooling system for a power conversion device that includes a radiator, a radiator fan supplying air to the radiator, and a power conversion device including a plurality of electric components and a casing housing the plurality of electric components inside. The casing includes a base portion which is formed of a non-metallic material and on which the plurality of electric components is placed and a cover portion formed of a metallic material, fixed to the base portion, and covering a periphery of the plurality of electric components. A refrigerant channel through which a refrigerant cooling the plurality of electric components flows is formed in the base portion of the casing, and the casing is disposed at a position where an airflow of the radiator fan is applied to the cover portion.
