What effect does the copper pipe in the icebox play?
A refrigerant used for circulating refrigerant.
There is refrigerant flow in the copper tube, and it can be cooled by liquid and gaseous transformation
The copper tube is partly the back air pipe, the back air pipe temperature is low, can condense, uses the iron to be easy to rust.
Reason analysis:The refrigerant eventually takes heat in the evaporator, heat the condenser, and the outside of the tube is connected to the heat sink. Copper is better than aluminum in heat conductivity, welding performance and mechanical strength is much better than aluminum, although the price is more expensive than aluminum, but the first choice is still copper.Now copper prices have risen sharply, and some refrigerators, air conditioners will be copper thin, or switch to aluminum pipe, the price is lower, the performance is also slightly worse than copper.
