More Information
Summary:A cooling apparatus includes: an annular internal liquid coolant flow channel that is mounted to a rotary electric machine main body, and in which an internal liquid coolant circulates around an outer circumference of the rotary electric machine main body, and an external liquid coolant passage portion through which an external liquid coolant passes, the external liquid coolant passage portion is connected to the internal liquid coolant flow channel by a connecting portion that is positioned vertically higher than the rotary electric machine main body, and the electric power converting apparatus includes a heat radiating surface that releases heat that is generated in the electric power converting apparatus, the electric power converting apparatus being mounted to the cooling apparatus such that the heat radiating surface and the internal liquid coolant can exchange heat at a position that is vertically lower than the connecting portion.
