Shell structure of electric scroll compressor

Abstract

The invention relates to the technical field of compressors, in particular to a shell structure of an electric scroll compressor, which comprises a shell body, a square platform, a plurality of square platform studs, a three-phase binding post, a communication connector, a power supply connector, a plurality of circuit board studs, a controller cover, a power supply connector joint surface and a communication connector joint surface, the shell body is provided with a lower step surface, a left step surface, a right step surface, a plurality of square platform screw holes, a mounting counter bore, a mounting through hole, two three-phase binding post screw holes, a power supply connector inner boss, a power supply connector outer boss, a power supply connector through hole, a communication connector inner boss and a communication connector through hole; heat generated by a main heating IGBT element of the controller is directly conducted to the inner wall of the shell body through the square platform and is cooled through a refrigerant, so that a more sufficient cooling effect is achieved, and the overheating problem of the controller is solved.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a casing structure of an electric scroll compressor. Background technique [0002] The electric compressor of the vehicle air conditioner is the core component of the air conditioner and refrigeration of the electric vehicle. The main heating elements of the controller are electronic components such as IGBT components and capacitors. When assembling, apply a medium such as thermal conductive silicone grease to contact with the plane set at the bottom of the shell body to ensure sufficient heat dissipation area to dissipate heat. The heat generated by the IGBT element is conducted through the controller heat dissipation plate to the medium and the bottom plane of the shell, and then to the shell. The heat is taken away through the flow of the refrigerant on the body, but this structure conducts heat dissipation through multiple layers of media, and its heat dissipation effect ...

AI Technical Summary

Problems solved by technology

[0002] The electric compressor of vehicle air conditioner is the core component of electric vehicle air conditioner refrigeration. The main heating elements of the controller are electronic components such as IGBT components and capacitors. The IGBT components of traditional controllers are all attached to the heat sink of the controller. During assembly, apply heat-conducting silicone grease and other media in contact with the plane set at the bottom of the housing body to ensure sufficient heat dissipation area for heat dissipation. The heat generated by the IGBT components is conducted to the medium and the bottom plane of the housing through the controller’s cooling plate, and then to the housing. On the body, the heat is taken away by the refrigerant flow contact, but this structure conducts heat dissipation through multi-layer media, and its heat dissipation effect is poor. Heat dissipation, resulting in overheating of the controller and shortening the life of the compressor or frequent shutdown of the compressor
