Motor-driven compressor

摘要

A motor-driven compressor (10) includes a housing (1) having an inlet port (17), a compression mechanism (18) for compression of refrigerant introduced from an external refrigerant circuit (111) via the inlet port into the housing (1), an inverter (30) having a heat-generating component (30A), an electric motor (19) driven by the inverter, and a rotary shaft (23) rotated by the electric motor (19) thereby to drive the compression mechanism. The electric motor (19), the compression mechanism (18) and the inverter (30) are aligned in the housing in axial direction of the rotary shaft (23). An inlet pipe (171) is connected to the inlet port (17). The housing (1) has an outer peripheral surface in contact with the inlet pipe. The heat-generating component (30A) of the inverter (30) is disposed adjacent to or in contact with the inlet pipe (171) so as to be thermally coupled to the inlet pipe.
