Finned tubes are the main components of heat exchangers. They are a series of tubes where fins have been added on the outside to increase the contact area with the outside fluid, to exchange heat and between the fluid inside the tube and the fluid outside the tube.

Finned tube heat exchanger:

Application areas

process industry
drying idustry
chemical industry
power generation
heating, ventilation and air conditioning industry

Product characteristics:

compact fin tube systems
hot-galvanised oval fin tubes
spiral wound finned tubes
extruded finned tubes
welded spiral finned tubes

This often-used type of heat exchangers consists of a tube package out of straight finned tubes, which are mostly arranged, staggered in the direction of air flow. The tubes are being welded or rolled in in two opposite tube plates, the distribution of media works via the tube chambers.

Those heat exchangers might also be executed with frames or casings.

The finned tube heat exchanger produced by Datang mainly uses laser welding fin and tube, with high degree of automation.

The fully automatic fin laser welding machine can realize one-time welding. Synchronous winding makes the fin foot and tube deeply welded, with high laser welding firmness and high binding force.
