LL Fin Tubes for Heat Exchanger | Overlapped L Type Fin Tube

What are LL Fin Tubes?

LL Fin Tubes is a type of fin tube. Its structural feature is that the root of the fin completely covers the outer surface of the base tube, which improves the heat exchange efficiency by increasing the contact area. This design can effectively enhance heat transfer and is commonly used in industrial heat exchange scenarios. ‌

Overlapped L-type fin tube structural characteristics

Overlapped L-type fin tubes adopt L-shaped fin structure, and the fins are tightly wrapped around the surface of the base tube through high-frequency welding or rolling process to form a high heat conduction channel. The root of the fin completely covers the outer wall of the base tube to ensure efficient heat transfer to the air. ‌

LL Fin Tubes for Heat Exchanger Application Scenarios

It is mainly used in high-temperature heat exchange scenarios in industrial fields such as petrochemicals, electricity, tobacco, papermaking, and environments that require corrosion resistance. Its bimetallic composite structure (such as steel base tube + aluminum fin) can adapt to more complex working conditions. ‌

LL Fin Tubes for Heat Exchanger Performance Advantages

‌Efficient heat dissipation‌: L-shaped design increases heat exchange area and releases heat quickly; ‌Corrosion resistance‌: Aluminum fins can resist atmospheric corrosion and are suitable for wet air coolers; ‌Stability‌: Bimetallic composite structure enhances vibration resistance.
