Aluminum Fins for Copper Pipe | Extruded Finned Tube

What is copper tube aluminum fin extruded finned tube?

Copper tube aluminum fin extruded finned tube is a composite structure heat exchange element that tightly attaches aluminum fins to the copper tube substrate through an extrusion process, mainly used to enhance heat transfer efficiency. Its core feature is to combine the thermal conductivity of aluminum with the corrosion resistance of copper, and is suitable for high temperature, high pressure and corrosive environments. ‌

Aluminum Fins for Copper Pipe Structure and Process

Copper tube aluminum fin extruded finned tube uses a special mold to extrude aluminum into a fin-like structure and seamlessly combine it with the copper tube substrate. During the production process, parameters such as extrusion force and temperature must be precisely controlled to ensure that the fins fit tightly with the tube body to avoid thermal resistance. ‌

Main features of copper tube aluminum fin extruded fin tube

‌High-efficiency heat transfer‌: Aluminum fins increase the heat exchange area and significantly improve the heat conduction efficiency; ‌Corrosion resistance‌: The copper tube substrate effectively resists chemical corrosion; ‌Durability‌: Tight structure, not easy to deform or fall off under long-term hot and cold conditions; ‌Applicability‌: Suitable for petrochemical, refrigeration equipment (such as evaporators, condensers), boiler water-cooled walls and other scenarios. ‌

Comparative advantages of copper tube aluminum fin extruded fin tube

Compared with traditional welded or rolled fin tubes, this process has the characteristics of no burrs, no wrinkles, high bonding strength, and surface treatment (such as anti-rust paint) further extends the service
