Low fin tubes Description
Low fin tubes are heat exchange components featuring ribs of specific height, spacing, and thickness mechanically rolled onto the outer surface of bare tubes. Primarily manufactured using the three-roll skew rolling method, they form an integral structure between the base tube and external fins, eliminating contact thermal resistance issues. With a finned ratio of 2-3, they enhance heat transfer by expanding the heat transfer area and disrupting the flow boundary layer, while utilizing thermal expansion and contraction effects to achieve self-cleaning functionality, offering superior anti-fouling performance compared to bare tubes.
The structural parameters of this fitting include fin height, spacing, and thickness, with fin efficiency decreasing as fin height increases. When applied in condensers and oil heat exchangers, staggered tube bundle arrangements can reduce the required heat exchange area by 30%. External fins effectively compensate for the low heat transfer coefficient on the air side.
The working principle of low fin tubes primarily relies on their unique fin structure design. By adding fins to the tube body, the heat exchange area is effectively expanded, improving thermal efficiency. Meanwhile, the low-fin design also reduces fluid resistance and lowers energy consumption. This structure enables low fin tubes to perform exceptionally well when handling high-viscosity and easily fouling fluids, making them widely used in heat exchange processes in industries such as petroleum, chemical, and power generation.
