What is Extruded Finned Tube?

An extruded fin tube is a type of heat exchanger tube that has fins formed on its surface. Aluminum finned tubes are typically manufactured by a process called extrusion, where the fins are pressed or rolled into grooves on the outer surface of the tube. This creates a secure and strong bond between the tube and the fins. This design also allows for easy cleaning and maintenance of the heat exchanger. The fins increase the surface area of the tube, allowing for enhanced heat transfer between the fluid inside the tube and the fluid outside, which also provide good corrosion protection to the base tube.

The aluminum fins fully cover the base tube, offering reliable protection against environmental corrosion while maintaining high thermal conductivity. Extruded fin tubes are especially suitable for outdoor applications and corrosive environments.
