    Wound L finned tube manufacturing process and close-up of fin structure
    Wound fin tubes are a type of heat exchanger tube that features fins wrapped around the outer surface of the tube. The fins are typically made from materials like aluminum or copper and are wound in a helical or spiral pattern. This design increases the surface area of the tube, enhancing its ability to transfer heat between the fluid inside the tube and the surrounding environment.
    Available Materials
    • Base tubes: carbon steel, copper, alloy, stainless steel
    • Fins: copper, aluminum 1060/1070, aluminum alloy 6063/6061
    Categories of Wound Finned Tubes
    • L-fin tubes
    • LL-fin tubes
    • KL-fin tubes
    Key Advantages
    • Trapezoidal section formed by rolling of L-shaped finned tube matches heat flow density distribution
    • Eliminates contact thermal resistance caused by gaps between fins
    • Compact design allows for more efficient heat exchanger configurations
    • Welded stainless steel base tubes provide robust construction resistant to mechanical damage
    Applications
    Wound L-type fin tubes are used in heat exchangers for air cooling or heating fluids such as air, water, oil, or gas. They are commonly found in industries such as oil & gas, power generation, marine, and HVAC&R.
    • Diesel Charge Air Coolers / Oil Coolers / Hydrogen Coolers
    • Waste Heat Recovery
    • Driers
    • Air Conditioning / Air Heaters
    • Generator Coolers
    • Steam Condensers
    Wound L finned tubes in industrial heat exchanger applications
    Conclusion
    Wound L-fin tubes are crucial components in various heat exchange applications, offering enhanced thermal performance and durability. The L-shaped fin design provides a larger surface area, significantly improving heat transfer efficiency. Their design and material selection are tailored to meet specific operational requirements, making them indispensable in industries ranging from power generation to chemical processing.
