Horizontal compressor

Abstract

The invention discloses a horizontal compressor which comprises a machine shell, a crankshaft, an air cylinder, a motor and a controller. A high-pressure cavity and a low-pressure cavity which are arranged formed in the axial direction of the machine shell in a spaced manner are defined in the machine shell. The machine shell is provided with an air sucking opening and an exhaust opening. The air sucking opening is communicated with the low-pressure cavity, and the exhaust opening is communicated with the high-pressure cavity. The crankshaft is arranged in the machine shell and extends in the axial direction of the machine shell. One end of the crankshaft stretches in the high-pressure cavity, and the other end of the crankshaft stretches in the low-pressure cavity. The air cylinder and the motor are arranged on the crankshaft in a spaced manner. The air cylinder is located in one of the high-pressure cavity and the low-pressure cavity. The motor is located in the other one of the high-pressure cavity and the low-pressure cavity. The controller is arranged outside the machine shell and is connected with the outer wall, adjacent to the low-pressure cavity, of the machine shell. According to the horizontal compressor of the embodiment, under the premise that high-temperature and high-pressure air exhaust of the horizontal compressor is ensured, stability of the working environment of the controller can be improved, the working environment is prevented from being influenced by high-temperature and high-pressure air exhaust of the horizontal compressor, and therefore the energy efficiency of the horizontal compressor is improved, and the service life of the horizontal compressor is prolonged.

Description

technical field [0001] The present invention relates to the technical field of compressors, in particular to a horizontal compressor. Background technique [0002] The compressor is an important part of the electric vehicle product, and the car manufacturer hopes that the controller of the compressor can be integrated with the compressor, and then installed on the electric vehicle together. Among them, the controller is an electronic component of the compressor, which needs to work normally in a relatively stable environment with a low ambient temperature, so that the controller can have high reliability, not easy to age, and good insulation effect, etc. . When the designer integrates the controller and the compressor, the internal temperature of the compressor must be controlled. Therefore, in order to ensure the normal use and life of the controller, the compressor in the related art is set to a low-pressure refrigerant environment. In this way, the controller does not I...

Problems solved by technology

However, when the inside of the compressor is made into a low-pressure refrigerant environment, the efficiency of the compressor will be greatly reduced, and the energy efficiency of the entire car's air conditioning system will also be affected.
