Bi-Metal Extruded High Finned Tube

The Extruded Fin Tube also known as Bimetallic Fin Tube is one of the most preferred finning processes for various applications. The fins are manufactured by Extruding the Fins on the Aluminum Muff Tube which is made to Fit with close tolerance over the Base Tube. The Extruded Fin Tubes or Bi-Metallic Fin Tubes are a type of fin tubes that have extruded fins from the outer surface. The base tube is made to slide inside an outer tube made of copper or aluminum. Then, this assembly of the inner and outer tube is passed through an automatic extrusion machine. During the extrusion process, the fin is extruded from the outer tube to the desired height, thickness, and density configuration.

Understanding Extruded Finned Tubes

Extruded finned tubes are specialized heat exchange components designed to optimize heat transfer efficiency. The manufacturing process involves extruding aluminum fins onto a tubular core, typically made of materials with high thermal conductivity such as copper or aluminum. This extrusion process ensures a robust bond between the fins and the tube core, enhancing the tube's overall performance.

Manufacturing Process of Extruded Finned Tubes

Tube Core Selection: The core tube, often made from copper, aluminum, or carbon steel, serves as the conduit for the fluid carrying heat. Its material is chosen based on thermal conductivity and application requirements.
Extrusion of Fins: Aluminum fins are extruded onto the outer surface of the tube core. This involves forcing the aluminum alloy through a shaped die, creating the desired fin profile. The extrusion process guarantees a strong bond between the fins and the core tube.
Fin Design: Depending on the application and thermal requirements, fin designs can vary. Options include straight fins, helical fins, or other specialized shapes to optimize heat transfer efficiency.
Surface Treatment: Post-extrusion, finned tubes may undergo surface treatments such as anodizing or coating to enhance corrosion resistance and improve heat transfer characteristics.
Assembly: Once the fins are extruded and treated, the finned tubes are assembled into heat exchanger units or other systems tailored to the specific application.
