The outstanding advantages of aluminum pipes

The aluminum tube and aluminum fin material are extruded in one go, which has a lower thermal resistance than the evaporator produced by traditional material iron tube technology, and enhances conduction refrigeration; The cooling efficiency coefficient of aluminum is 237W/(m), and the thermal conductivity coefficient of steel is 80W/(m), so aluminum pipes have higher heat transfer efficiency than traditional smooth steel pipes. According to the testing conducted by the National Commercial Refrigeration Equipment Quality Supervision and Testing Center, the heat transfer coefficient of aluminum tubes is K ≈ 9~lw/m2.0 ° C at an evaporation temperature of -30 ° C-0 ° C, and the heat transfer coefficient of steel tubes is K ≈ 7~8w/m2.0 ° C at an evaporation temperature of -30 ° C-0 ° C. Therefore, it can be concluded that the heat transfer efficiency of aluminum tubes is 1.3 times that of steel tubes. For the same cold storage (under the same load), compared with steel pipes and aluminum pipes with the same evaporation area, aluminum pipes have a faster cooling speed and significant energy-saving effect.

Low installation and maintenance costs

Based on an evaporation area of 1m2, the weight of the 38 steel pipe in the middle is 18  4kg, The weight of aluminum pipes with the same evaporation area is only about 1/6 of that of steel pipes, which greatly saves lifting and maintenance costs and shortens the engineering installation cycle. Moreover, steel pipes are prone to rusting and require frequent painting and maintenance in the later stages, while the surface of aluminum pipes has undergone oxidation treatment, resulting in clean inside and outside of the pipes.

Extended service life

The smoothness of the inner and outer surfaces of finned tubes is greatly improved compared to traditional steel pipes, resulting in a clean system, reduced failure rates, and extended compressor service life. External surface anodizing treatment improves corrosion resistance in low-temperature environments, thereby extending the service life of the entire system.
