Wrapped Finned Tubes, also known as Wrap Around Fin Tubes, are high-efficiency heat exchange elements that fix fins to the outer surface of a base tube through a mechanical wrapping process. Their core advantages lie in high heat transfer efficiency and structural stability.
I. Technical Characteristics of Wrapped Finned Tubes
Fin Types: Including Knurled Fin (mechanically interlocked), LL Fin (double-layer overlapping), and Perforated L Fin (with tear-off holes), optimizing airflow turbulence and heat exchange efficiency through different structures.
Material Compatibility: The base tube can be made of copper (C1100/C1220), aluminum (A1100/A1050/A1060), etc., with fin heights typically ≤16mm, suitable for various industrial applications.
