[0002] The air conditioner accumulator is an important part of the compressor in the air conditioner. It plays the role of storage, gas-liquid separation, filtration, silencing and refrigerant buffering. The refrigerant is mostly buffered in the copper tube, which is also called the red copper tube, a kind of non-ferrous metal tube, and is a pressed and drawn seamless tube. The copper tube has good electrical and thermal conductivity. It is the main material for the conductive accessories and heat dissipation accessories of electronic products, and has become the first choice for modern contractors to install water pipes, heating and cooling pipes in all residential commercial houses.

[0003] During the production process of existing copper pipes, dust and debris are attached to the outer wall of the copper pipe. Therefore, the copper pipe often needs to be cleaned and then dried after cleaning.
