Thats because the surface of the fins is larger than the surface of the tubes. Now lets talk about the main pros and cons of aluminum and copper . Aluminum Pros Aluminum offers effective heat transfer at a lower cost than copper .

How is an extruded finned tube heat exchanger formed?How is an extruded finned tube heat exchanger formed?Extruded Finned Tube This fin type is formed from a bi-metallic tube consisting of an aluminum outer tube and an inner tube of almost any material. The fin is formed by rolling material from the outside of the exterior tube to produce an integral fin with excellent heat transfer properties and longevity.Heat Exchanger Finned Tube 8 types you should know about How does a fin fin heat exchanger work?How does a fin fin heat exchanger work?Tube Fin Heat Exchangers, also called finned coil heat exchangers, consist of tubes that pass through a dense fin stack that is mechanically supported by a mounting frame. Fluid passes through the tube coils, conducts heat to the fins and dissipates heat to air forced through the heat exchanger.Tube Fin Heat Exchangers Boyd Corporation
KRN manufactures Aluminum fin - copper tube and as well with Aluminum tube and Aluminum fins condenser coils in hydrophilic and hydrophobic fin material thickness ranging from 0.1mm to 0.19mm using 5 mm, 7 mm, and 9.52 mm (3/8) in internally grooved and smooth tubes.

Elfin finned tubes are used extensively in hydro power generator coolers Bulleted Fins. With an external appearance similar to Elfin Finned Tubes, bulleted finned L Finned Tubes. One common type of finned tube is the L fin. Receiving its name from the LL Finned Tube. Manufactured in the same way as the L finned tube, the LL fin has ov KL Finned Tube. KL Fin Tubes are also called knurled finned tubes. The fin is wrapped G Embedded Finned Tube. The main design feature of Embedded Fin tubes involves the Extruded Finned Tube. This fin type is formed from a bi-metallic tube consisting of an Wire Finned Tube. Wire loop tube is a high efficiency tube consisting of a series of
