Description

Technical Field

[0001] The utility model relates to the technical field of edge pressing devices, in particular to an edge pressing device which is convenient for fixing a fin tube. Background Art

[0002] As a highly efficient heat exchange element, finned tube plays an important role in industrial production, refrigeration, air conditioning and other fields. It significantly improves the heat exchange efficiency by increasing the heat dissipation area and increasing the air flow rate. Finned tubes are widely used in petrochemical, machinery, metallurgy, rubber, printing and dyeing, medicine, food, electricity, automobile, drying and other industries. They are important heat transfer elements of decomposition furnace, conversion furnace convection section, air preheater, coal economizer, heat exchanger, crystallizer, radiator and heat pipe technology. In particular, steel fin radiators are widely used in industrial and commercial buildings such as offices, residences, hotels, workshops, greenhouses, etc., and play an excellent role in heating. The exposed areas of finned tubes should be prevented from dripping with rainwater, kept dry as much as possible, and not too close to the ground to prevent irrigation in the greenhouse from corroding the finned tubes. After the maintenance of the finned tubes, the service life of the finned tubes will be greatly increased.
