Problems solved by technology

Since the inhaled heat does not come from the cooled medium, the suction heat exchange inside the suction connecting pipe is an ineffective heat exchange, which directly causes the increase of the suction specific volume and reduces the efficiency of the compressor.

Abstract

The invention discloses a compressor assembly which comprises a compressor and an air sucking pipe assembly. The compressor comprises a shell and a compression mechanism. The compression mechanism is provided with a compression cavity. The air sucking pipe assembly is used for guiding refrigerants into the compression cavity. The air sucking pipe assembly comprises a connecting pipe, an air guiding pipe and an air sucking pipe. The part, located outside the shell, of the connecting pipe is provided with a first welding pipe section. The first welding pipe section and the outer end of the connecting pipe are spaced. The inner end of the air guiding pipe penetrates in the connecting pipe and is communicated with the compression cavity. The air guiding pipe is provided with a second welding pipe section. The second welding pipe section and the first welding pipe section are connected in a laser welding manner, and the inner end of the air sucking pipe penetrates in the air guiding pipe and is communicated with the air guiding pipe. According to the compressor assembly, due to the fact that the non-exterior end of the air guiding pipe and the non-exterior end of the air sucking pipe are connected in a laser welding manner so that welding sealing can be formed between the connecting pipe and the air guiding pipe, and the reliability of the compressor assembly can be improved.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a compressor assembly. Background technique [0002] In the related art, during the operation of the existing high back pressure compressor, the compressor casing contains high temperature and high pressure gas. There is a large temperature difference between it and the gas in the suction pipe channel, and the gas in the suction pipe directly absorbs heat from the shell gas through the suction pipe wall, which increases the suction heat transfer. Since the inhaled heat does not come from the cooled medium, the suction heat exchange inside the suction connecting pipe is an ineffective heat exchange, which directly causes the specific volume of the suction to increase, resulting in a decrease in the efficiency of the compressor. [0003] In order to overcome the above defects, many compressor manufacturers will increase the heat insulation pipe of engineering plastics to reduc...
