2026-05-18

1. Introduction In the context of global energy conservation and carbon reduction, and the continuous upgrading of industrial heat exchange technology, the demand for high-efficiency, compact, and reliable heat transfer elements is increasingly urgent. Spiral finned tubes, as a classic high-efficiency heat transfer structure, have been widely used in various heat exchange systems due to their ability to enhance medium turbulence and expand heat transfer area. However, traditional spiral finned tubes (such as rolled or welded types) often have defects such as loose bonding between fins and base tubes, high gap thermal resistance, and poor structural stability, which limit their application in high-temperature, high-pressure, and corrosive harsh working conditions. Brazed spiral finned tubes, as an upgraded product of spiral finned tubes, adopt advanced brazing technology to realize the metallurgical bonding between fins and base tubes, fundamentally solving the bottleneck of traditional spiral finned tubes.
