Serrated Fin

What are Serrated Fins?

Serrated fins are heat exchange elements with a serrated geometry created on the pipe surface through a special process. They are widely used in industrial heat exchange applications. Their unique design effectively improves heat transfer efficiency and reduces energy consumption.

Serrated Fin Structural Features

Serrated fins are fixed to the base pipe surface through high-frequency welding or mechanical expansion, creating a tightly packed serrated structure. This design not only increases the surface area but also enhances air-side heat transfer efficiency by disrupting the airflow boundary layer.

Serrated Fin Functional Advantages

High-Efficiency Heat Transfer: The serrated shape increases the heat transfer area, improving heat exchange efficiency by approximately 30%-40%.

Anti-Fouling and Dust: The serrated structure disrupts fluid flow, reducing fouling and extending service life.

Strong Structural Reinforcement: The high-frequency welding process ensures a seamless connection between the fins and the base pipe, enhancing overall strength and durability. ‌

Serrated Fin Applications

Mainly used in waste heat recovery systems in the petrochemical, power, and metallurgical industries, as well as commercial and industrial heating and cooling systems. Examples include:

High-frequency welded fin tubes in the petrochemical industry

Circular fin serrated radiators in commercial buildings

Industrial spiral serrated fin tubes
