Abstract:
1. A motor-driven compressor to be connected to an external refrigerant circuit, comprising: a housing including an intermediate housing and a front housing connected to the intermediate housing, the intermediate housing having an inlet port adjacent to the front housing; a compression mechanism accommodated in the intermediate housing for compression of refrigerant introduced from the external refrigerant circuit via the inlet port into the intermediate housing; an inverter accommodated in the front housing and having a heat-generating component; an electric motor accommodated in the intermediate housing and driven by the inverter; and a rotary shaft rotated by the electric motor to drive the compression mechanism, wherein the compression mechanism, the electric motor, and the inverter are aligned in order in an axial direction of the rotary shaft, the intermediate housing is positioned next to the front housing in the axial direction, and an inlet pipe is connected to the inlet port; wherein the inlet pipe extends in the axial direction from the inlet port along and in contact with outer peripheral surfaces of both the intermediate housing and the front housing, and the heat-generating component of the inverter is disposed adjacent to or in contact with the inlet pipe so as to be thermally coupled to the inlet pipe.
