Finned tube is a kind of heat exchange element. In order to improve the heat exchange efficiency, the surface area of the heat exchange tube is usually increased by fins to increase the external surface area (or internal surface area) of the heat exchange tube, so as to achieve the purpose of improving the heat exchange efficiency. Such a heat exchange tube.
Manual suits are called manual suits. It is the use of tools, relying on human power to press the fins one by one. This method has a limited press force of the fins, so the interference of the set is small, and the fins are liable to loosen.
The mechanical assembly fins are made on a finning machine. Since the fins are pressed by mechanical impact force or liquid pressure, the press-in force is large, so a large amount of interference can be used. The bonding strength between the fins and the tube is high and it is not easy to loosen. Mechanically driven machine sets have high productivity, but they are noisy, have poor safety, and have poor working conditions for workers. Although there is no such problem as the hydraulic transmission, the equipment is expensive, and the technical requirements for the use of maintenance personnel are high, and the productivity is also lower.
