Kind Code:
A1
Abstract:
[Problem] To provide an electric compressor for cooling a component of an inverter control device that is not in contact with a partition wall that partitions a motor chamber also serving as a suction chamber of a housing member accommodating an electric motor and an inverter chamber of a housing member accommodating an inverter control device. [Solution] A housing 6 of an electric compressor 2 is partitioned by a bottom wall 71 into a motor housing 31 accommodating an electric motor 3 and an inverter housing 7 accommodating an inverter control device 5, and these housings 7 and 31 are connected to each other through a bolt 34 having thermal conductivity. The motor housing 31 has, on a bottom wall 71 side thereof, a refrigerant inflow port 35, and has a motor chamber 39 that is a part of a wall surrounding the bottom wall 71 and also serves as a suction chamber. The inverter housing 7 has a cylindrical heat-conductive protrusion 73 into which the bolt 34 passing through the motor chamber 39 is inserted and which is formed on the bottom wall 71, and the protrusion 73 protrudes into an inverter chamber 9, so that the inverter control device 5 is cooled.
