Fin Types for Aluminum Fins on Copper Pipe
At Datang Finned Tube, we manufacture various types of aluminum fins for copper pipe assemblies. The selection of fin types depends heavily on the specific manufacturing process and surface geometry, which directly influence heat transfer efficiency, air resistance, anti-fouling capabilities, and production costs.
Here is a comprehensive breakdown of the core fin types we offer to help you choose the ideal configuration for your project.
-
Extruded Fins (High-Performance Bimetallic Fin Tubes)An aluminum muff tube is fitted over the base copper pipe. It is then cold-extruded through a specialized rolling mill. Under high pressure, the aluminum material is deformed into high fins, creating a seamless, tight mechanical bond between the copper inner tube and the outer aluminum liner.Harsh industrial environments, Air-Cooled Heat Exchangers (ACHE), oil refineries, and petrochemical cooling systems.
-
Tension-Wrapped Fins (L-Foot, LL-Foot, KL-Foot Fins)Manufacturing Process: A thin aluminum strip is precisely formed into an “L”, “LL”, or “KL” cross-section under high mechanical tension and wrapped tightly and continuously around the outer surface of the copper pipe.Maximum Cost-Efficiency,Enhanced Contact Area.Common Applications: Regular industrial HVAC systems, low-pressure air coolers, and standard air heating applications.
-
Mechanically Expanded Plate/Block Fins (Fin Pack / Gilled Tubes)Aluminum foils are pre-stamped into large, multi-hole plates with precise collars using high-speed stamping presses. The copper tubes are then inserted through these sheets and “expanded” using mechanical or hydraulic tube expanders, forcing an interference fit between the copper outer wall and the aluminum fin collars.Air conditioners,heat pump evaporators, and HVAC condenser coils.
How do you Manufacture Extruded Fins (High-Performance Bimetallic Fin Tubes)?
This process involves a “cold extrusion” technique. A seamless outer tube made of a ductile metal (typically aluminum or copper) is tightly fitted over the bare base tube. The composite tube is then forced through an extrusion die under immense pressure, which raises the outer metal to form continuous, seamless helical fins. Because the fins and the base tube become a single solid piece, this method provides exceptional corrosion resistance and superior thermal contact efficiency.
How do you Manufacture Tension-Wrapped Fins (L-Foot, LL-Foot, KL-Foot Fins)?
These types are produced by spirally winding a metal strip onto the tube under constant tension. The difference lies in the specific technique: L-Fin involves simply bending the strip into an “L” shape and wrapping it around the tube; LL-Fin extends the foot of the fin to overlap and fully cover the tube’s outer surface for added corrosion protection; and KL-Fin involves knurling (roughening) the tube surface before winding, embedding the fin foot into the grooves to significantly increase bonding strength and temperature resistance.
How do you Manufacture Mechanically Expanded Plate/Block Fins (Fin Pack / Gilled Tubes)?
Advanced high-speed presses stamp aluminum foils into precision-holed fin sheets with built-in collars. Seamless “U”-shaped copper tubes are then laced through the stacked fin matrix. Next, a high-pressure expander drives bullet mandrels inside the tubes, plastically expanding the copper outer walls into a tight interference fit with the aluminum collars to eliminate thermal resistance. Finally, return bends are brazed and the assembly undergoes rigorous high-pressure leak testing before shipment to guarantee maximum heat transfer efficiency.
