In the condenser, the main role of the purple copper tube is to carry out heat exchange. After high-frequency heating and annealing, the crystal structure of the purple copper tube is more regular, reducing the internal lattice defects and thus improving its thermal conductivity. This allows heat to be transferred more quickly and efficiently between the medium inside and outside the tube, improving the heat exchange efficiency of the condenser. For example, in air-conditioning condensers, annealed copper tubes can increase their thermal conductivity by about 10% - 15% compared to untreated ones, effectively improving the cooling effect of air-conditioners.

The annealing process can also improve the surface condition of copper tubes, making the surface more uniform and dense. In the condenser working process, the copper tube will come into contact with various cooling media, such as air, water or refrigerant. A good surface condition can enhance the corrosion resistance of copper tubes to these media, reduce the thinning of the tube wall due to corrosion, perforation and other problems, and extend the service life of the condenser.
