COOLING STRUCTURE FOR INVERTER AND CAPACITOR ACCOMMODATED INTEGRALLY WITH MOTOR IN HOUSING OF MOTOR, MOTOR UNIT WITH COOLING STRUCTURE, AND HOUSING
First Claim
1. A cooling structure for an inverter and a capacitor accommodated integrally with a motor in a housing of said motor, said cooling structure comprising:
- a flow channel through which a coolant flows, provided between said motor and said inverter, anda communication channel provided between said motor and said capacitor, establishing communication between said flow channel and a region outside said housing to allow flow of the coolant between said flow channel and the region outside said housing.

Abstract
Inside a housing, there are provided a motor generator (MG), an IPM, and a smoothing capacitor. Between the MG and the IPM, there is provided a cooler through which a coolant liquid flows, provided in an inclined manner to form contact with the top face of the IPM. Between the MG and the smoothing capacitor, there are provided a first communication channel through which an LLC flows from a region outside the housing into the cooler, brought into contact with a lateral face of the smoothing capacitor, and a second communication channel through which the LLC flows from the interior of the cooler to the region outside the housing.
