Motor compressor for vehicle air conditioner

Abstract

The invention discloses a motor compressor for a vehicle air conditioner, which comprises a compressor pump body, a motor assembly, and a motor driver, and is characterized in that: the motor assembly is integrally connected with the compressor pump body; and a motor casing of the motor assembly is embedded with a motor terminal which is butted to a driver plug of the motor driver. Because of thestructure, the device has the following advantages that: 1, the integrated structure of the air condition compressor is realized, the volume of the motor compressor is reduced, and the space of the finished automobile and the complicated conductor jointing are saved; 2, the modular design realizes resource saving and sharing and the independent supply of modules; 3, a cooling liquid per se is used for cooling to save the conventional external cooling fins and cooling fans; and 4, the product quality control is convenient, the modules can be replaced, and the maintenance cost at the later stage is reduced.

Description

[0001] Involved areas [0002] The invention relates to the field of automobile refrigeration, in particular to an electric compressor for an automobile air conditioner. Background technique [0003] With the continuous shortage of oil resources and the development of power battery technology, electric vehicles are gradually being introduced to the market and have entered the vision of consumers. Electric vehicle air conditioner electric compressors have been developed immediately. The electric compressors are driven by electric motors and powered by batteries. The motor adopts a DC permanent magnet synchronous motor and is controlled by a driver, which has the advantages of low noise and high efficiency; the speed can be controlled externally and saves energy; the electric compressor solves the cooling demand of electric vehicles. [0004] The current electric compressor is generally connected to the motor by the pump body of the compressor, and the motor driver is externall...

AI Technical Summary

Problems solved by technology

[0004] The current electric compressor generally connects the motor with the pump body of the compressor, and the motor driver is externally connected. However, due to the heat generated by the driver body, heat sinks and cooling fans must be arranged around it, resulting in a large volume of the driver body, and a certain layout space is required for the external connection. The cooling fan also needs a power supply; a long wire is required between the drive output and the compressor, which increases costs and risks. In addition, the compressor and the motor as a whole must establish a motor production line at the compressor manufacturer, increasing investment

[0005] Solving the current problems of oversized electric compressors and complex production processes, and reducing the production cost of compressors are problems that need to be solved in the prior art
