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.
