Power Conversion Apparatus
First Claim
1. A power conversion apparatus, comprising:
- a power semiconductor module for converting direct-current power into alternating-current power;
a first flow channel forming body for housing the power semiconductor module; and
a cover for fixing the power semiconductor module to the first flow channel forming body, wherein;
the power semiconductor module includes a power semiconductor element, main terminals electrically connected to the power semiconductor element, and a case for housing the power semiconductor element;
the cover has a recessed portion and an opening provided in a bottom surface portion of the recessed portion;
the power semiconductor module is placed to be fitted into the recessed portion;
the power semiconductor module is fixed to the cover so that the main terminals pass through the opening; and
the case and an inner wall of the recessed portion have an airtight structure.

Abstract
A power conversion apparatus includes: a power semiconductor module (150a); a flow channel forming body (20) for housing the power semiconductor module (150a); and a cover (5) for fixing the power semiconductor module (150a) to the flow channel forming body (20), and the power semiconductor module (150a) includes a power semiconductor element, main terminals (157b, 158b) electrically connected to the power semiconductor element, and a case for housing the power semiconductor element, the cover (5) has a recessed portion (5c) and an opening (5a) provided in a bottom surface portion of the recessed portion (5c), the power semiconductor module (150a) is placed to be fitted into the recessed portion (5c), the power semiconductor module (150a) is fixed to the cover (5) so that the main terminals (157b, 158b) pass through the opening (5a), the case and an inner wall of the recessed portion (5c) have an airtight structure, and therefore prevents intrusion of a coolant into the power semiconductor module having a double-sided cooling structure and outflow of the coolant to outside of the module.
