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.

Fin Tube Heat Exchanger/Radiator
Fin Tube Heat Exchanger/Radiator
A Finned Tube Heat Exchanger (or Radiator) is a thermal management device that enhances heat transfer efficiency by combining tubes with extended surfaces (fins). The fins significantly increase the heat exchange area, allowing rapid dissipation of heat from fluids (e.g., air, water, oil, or refrigerants) to the surrounding environment. It is widely used for both heating and cooling applications across industries.

Shell and Tube Heat Exchangers
Shell and Tube Heat Exchangers
A Shell and Tube Heat Exchanger is a robust and versatile thermal device designed to transfer heat between two fluids (e.g., liquidliquid, gasliquid) through a series of tubes enclosed within a cylindrical shell. One fluid flows through the tubes (tube side), while the other circulates outside the tubes within the shell (shell side). Its modular design and highpressure tolerance make it a cornerstone of industrial heat exchange systems.

Air Cooled Heat Exchanger/Air Cooler/Fin Fan Cooler
Air Cooled Heat Exchanger/Air Cooler/Fin Fan Cooler
An Air Cooler (Air Cooled Heat Exchanger) is a highly efficient cooling device that transfers heat from industrial fluids (e.g., water, oil, or chemicals) to ambient air through finned tubes and fans. It eliminates water dependency, reduces environmental impact, and is widely adopted in waterscarce or hightemperature environments.

Fin Fan Cooler,Oil Cooler,Air Cooler and Air Cooled Heat Exchangers
Fin Fan Cooler, also known as an Air Cooled Heat Exchanger, is a type of heat exchanger used to cool different processes in the refining, petrochemical, and chemical processing industries. Using a series of fans, fin fan coolers move low temperature atmospheric ambient air over multiple rows of finned tubes in order to cool internal process fluids. Like all heat exchangers, they are often used in situations where a process generates excess heat that can’t be used in other ways.

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.
