Description
Technical Field

[0002] The refrigerator compressor is mainly used to compress the refrigerator refrigerant. There are three pipes on the compressor. One is connected to a relatively thin pipe, which is a high-pressure pipe (exhaust pipe). The refrigerant is compressed by the compressor and discharged, and the temperature is relatively high; one is connected to a copper pipe with a diameter of about 8mm, which is a low-pressure pipe (return air pipe). The refrigerant flows back into the compressor after the pressure is changed, and the relative temperature is low, about the same as the ambient temperature (when there is too much refrigerant, the return air pipe will be frosted); the other one is welded with a section of the pipe, blocked by welding or sealed with ultrasonic welding, which is a compressed process pipe. The process pipe is the same size as the return air pipe.
[0003] The exhaust pipe is welded using a welding device during the manufacturing process. The exhaust pipe is easily detached during welding with the existing welding device, which reduces the stability and aesthetics of the welding. In addition, the welding process is prone to welding leaks due to untimely rotation of the exhaust pipe. Utility Model Content
