Embodiment Construction

[0064] Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1 to 9 .

[0065] FIG. 1 shows an external appearance side view of an inverter-integrated electric compressor 1 according to an embodiment of the present invention. The inverter-integrated electric compressor 1 has a casing 2 constituting its casing. The housing 2 is formed by integrally fastening a motor housing 3 accommodating an electric motor (not shown) and a compressor housing 4 accommodating a compressor (not shown) tightly by bolts 5 . The motor casing 3 and the compressor casing 4 are made by die casting.

[0066] An electric motor and a compressor (not shown) accommodated in the motor housing 3 and the compressor housing 4 are connected via a motor shaft, and the compressor is driven by rotation of the electric motor. At the rear end of the motor housing 3 (the right side in FIG. 1 ), a suction port 6 is provided. The low-pressure refrigerant gas sucked into the mot...

Abstract

An inverter-integrated electric compressor enhances vibration resistance of an inverter apparatus integrated with a housing without degrading cooling performance, reduction in weight, or the ease of assembly of the inverter apparatus. An inverter-integrated electric compressor 1 has an inverter apparatus 22 integrated with an inverter storage box 11 of a housing 3 . The inverter apparatus 22 includes a metal plate 23 secured in an inverter storage box 11 ; a plurality of power semiconductor switching elements 24 mounted on the metal plate 23 ; a power substrate 25 on which a power-related control circuit for operating the power semiconductor switching elements 24 is mounted; and a busbar assembly 26 formed by integrating a plurality of busbars with an insulator. The metal plate 23 includesa protrusion 33 extending in a width direction perpendicular to a motor shaft direction L of an electric motor.

Description

technical field [0001] The present invention relates to an inverter-integrated electric compressor mainly suitable for vehicle air conditioners. [0002] The present invention is based on Japanese Patent Application Nos. 2006-315771 and 2006-315772, the contents of which are incorporated herein by reference. Background technique [0003] In recent years, in the automotive industry, in order to cope with energy environmental problems, the development and market introduction of vehicles using electric power, such as hybrid vehicles and electric vehicles, or fuel cell vehicles, has been rapidly promoted. [0004] On the other hand, these vehicles are equipped with an electric compressor driven by an electric motor powered by electricity, unlike conventional air conditioners. [0005] In addition, the above-mentioned electric compressor is a hermetic electric compressor in which a compressor and an electric motor are built in a casing, and a DC power from a power supply is conv...
