Abstract
A motor-driven compressor includes a housing having an inlet port, a compression mechanism for compression of refrigerant introduced from an external refrigerant circuit via the inlet port into the housing, an inverter having a heat-generating component, an electric motor driven by the inverter, and a rotary shaft rotated by the electric motor thereby to drive the compression mechanism. The electric motor, the compression mechanism and the inverter are aligned in the housing in axial direction of the rotary shaft. An inlet pipe is connected to the inlet port. The housing has an outer peripheral surface in contact with the inlet pipe. 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.
