Our high - frequency welded fin tubes are precision - engineered heat - exchange components, playing a crucial role in enhancing
thermal transfer efficiency across diverse industrial applications. These tubes feature fins firmly attached to the base tube via
advanced high - frequency welding technology, ensuring superior structural integrity and heat - transfer performance.
Products Description
High-frequency laser finned tube
Construction and Technology
1. Base Tube * Available in various materials such as carbon steel, stainless steel (e.g., 304, 316), and copper alloys. The
selection depends on specific application requirements like corrosion resistance, temperature, and pressure conditions. For
instance, stainless steel base tubes are ideal for acidic or high - salinity environments in chemical processing, while
copper alloys suit HVAC systems demanding excellent thermal conductivity.
* Precisely manufactured to strict dimensional tolerances, ensuring a smooth inner surface for unimpeded fluid flow,
which is vital for maintaining consistent heat - transfer rates.
2. Fins * Typically made from materials matching or complementary to the base tube for optimal thermal compatibility. Common fin
materials include aluminum (for its high thermal conductivity and lightweight nature, perfect for HVAC and refrigeration),
carbon steel (cost - effective for general industrial heating), and stainless steel (for harsh, corrosive environments).
* The fin shape is usually helical, maximizing the surface area exposed to the surrounding medium (air or other heat -
exchange fluids). This helical design also promotes turbulent flow, disrupting boundary layers and enhancing heat transfer.

Performance Advantages
1. High Heat - Transfer Efficiency * The increased surface area provided by the fins, combined with the efficient thermal
connection from high - frequency welding, allows for significantly enhanced heat exchange. In heat exchanger applications,
this means faster heating or cooling of fluids, reducing energy consumption and operational costs. For example, in a steam
- to - air heat exchanger, our fin tubes can achieve heat transfer coefficients that are [X]% higher than standard plain
tubes, leading to more compact and cost - effective heat exchanger designs.
* The turbulent flow promotion by the helical fins further boosts heat transfer by minimizing
the thickness of the thermal boundary layer, ensuring that the fluid temperatures are quickly and evenly adjusted.
2. Durability and Longevity * The metallurgical bond from high - frequency welding ensures excellent resistance to thermal
stress, which is critical in applications with frequent temperature fluctuations (e.g., industrial boilers, refrigeration
systems). Unlike mechanically bonded fins that may loosen over time due to thermal expansion and contraction, our welded
fins remain securely attached, maintaining consistent performance over the product's lifespan.
