Mastering Heat Exchange: A Guide to Finned Tube Heat Exchanger Banks
When it comes to industrial thermal management, finned tube heat exchanger banks (often called finned tube coils) are the unsung heroes. Whether you are managing an HVAC system, a power plant, or a chemical processing facility, the efficiency of your heat transfer depends heavily on one thing: the geometry of the tube layout. At their core, finned tubes increase the surface area of the pipe, allowing for much faster heat dissipation. But how these tubes are connected—using U-bends, S-curves,... -

Bent Finned Tubes: Optimizing Heat Transfer for Complex Spaces
A bent finned tube is essentially a finned tube that has been precisely formed into a specific curvature – U-bends, coils, serpentine shapes, or custom angles – after the fins are attached. The fins, typically helical (spirally wound) or longitudinal, are securely bonded (often welded) to the base tube. The bending process requires specialized expertise to maintain the integrity of both the tube and the fin attachment without compromising performance.

Extruded Fin Tube
Datang produces Extruded Fin Tubes which are manufactured by cold rotary extrusion process. The Extruded Fin is formed from an outer aluminium tube with a large wall thickness, which is aligned over an inner base tube. The two tubes are pushed through three arbors with rotating discs that literally squeeze or extrude the aluminium fins up and out of the muff material in a spiral shape in one operation. The process of extrusion hardens the fins and prevents dissimilar metal contacts at the fin root. The exposed external surface is aluminium and there are no minute gaps between adjacent fins where moisture can penetrate. This ensures good efficiency that is expected when using an extended surface for heat transfer. During the finning process a tight mechanical bond is made between the finned aluminium outer tube and inner base tube of the required metal.
