Finned tube heat exchanger is one of the earliest and most successful discoveries in the process of improving tubular heat transfer. This method is still the most widely used of all the various tube heat exchange surface heat transfer enhancement methods. It is not only suitable for single fin tube heat exchangers in power, chemical, petrochemical, air conditioning engineering and refrigeration engineering is widely used.

Finned tube heat exchangers are widely used in power, chemical, petrochemical, air conditioning engineering and refrigeration engineering, such as surface air coolers, air heaters, fan coils used in air conditioning engineering. The cold fan evaporator and frost-free refrigerator evaporator used in refrigeration engineering are not only suitable for single-phase fluid flow, but also have great value for phase conversion heat

Most of the finned tube heat exchangers used for clean gas have adopted the new and efficient finned surface structure, which has obtained remarkable heat transfer enhancement effect.
