Excellent performance of metal finned tube
Finned tube is a heat exchanger composed of circular tube or light tube, so how to improve the heat transfer of circular tube? Murphy suggests one of the more efficient methods is to use an extended surface on the outer surface of the pipe, namely the flue gas side, to make a finned tube. Assume finned tube heat transfer area of the actual light tube surface area several times, although the flue gas heat transfer coefficient is still very low, but reflect on the tube surface area of light will greatly increase the heat transfer effect, making the whole process of heat transfer enhancement, the total heat transfer of a certain situation, make the metal consumption of equipment is reduced, economy increase.
The metal finned tube is made of aluminum tube rolled as a whole, which is called aluminum-rolled finned tube. It has no contact thermal resistance, high strength, heat resistance and mechanical vibration, good thermal expansion performance, and has considerable expansion heat transfer surface. This kind of fin tube heat exchanger, the effect of the series or wrap heat exchanger, is a very wide use of heat exchanger. The metal finned tube can also be directly rolled by steel or copper tube.
Laser welding finned tube is a new type of stainless steel, wear-resisting, heat transfer materials, is a kind of energy-saving heat transfer element, for high frequency power supply of heat, heat the steel strip, steel pipe at the same time, make its welded together as a whole, has high in thermal efficiency, heat dissipation area is large, long service life, adapt to the temperature range, high pressure, etc.
