Finned tube heat exchanger is a device that enhances heat transfer by adding fins to the surface of the heat exchange tube. The function of the fin is to increase the surface area of ​​the heat exchange tube, thereby improving the heat transfer efficiency. This design is widely used in power, chemical, petrochemical, air conditioning engineering and refrigeration engineering. Structural features of finned tube heat exchanger The basic structure of the finned tube heat exchanger includes heat exchange tubes and fins. The heat exchange tube is the main part of the heat transfer, while the fins increase the heat transfer efficiency by increasing the surface area. The fins can be straight, corrugated or serrated, which can destroy the fluid boundary layer, reduce thermal resistance, enhance turbulence, and further improve the heat transfer effect.
