Spiral Finned Tube Application Industry

Spiral fin tube is a widely used fin tube at present, it is a kind of high frequency welding heat dissipation component which is specially designed for serial and wound fin defects. Its heat transfer range is several times to tens of times of the bare tube, which can strengthen heat transfer, reduce flow resistance, balance heat transfer, greatly reduce the size of the machine and equipment, reduce the loss of metal materials, and further increase the economy and reliability of the machine and equipment. The high frequency welding of spiral finned tube is to heat the strip and steel pipe surface to plasticity or melting, and then make full use of the surface effect and proximity effect of high frequency current to achieve welding under the working pressure of the surrounding strip steel, so that the strip steel and pipe fittings are firmly welded.

Generally, the distance and height of the fin tube radiator mainly directly affects the composition of the fin, and the fin rate is closely related to the membrane heat transfer of the tube surface and the medium in the tube. If the gap between the surface of the tube and the membrane heat transfer coefficient in the tube is large, a fin tube with a larger fin should be used, such as steam heating the air. When the phase change appears on one side of the medium, the gap between the heat transfer coefficient is relatively large, such as the circulation of heat exchange air, finned tube heat exchangers can be used. If there is no phase change in heat transfer between air and air, or heat exchange between water and water, bare tubes are usually suitable. Of course, low fin tubes can also be used, because this time is a weak heating coefficient, strengthening either side will have effect. However, the direct effect of excessive fin ratio is not significant, and threaded or grooved tubes can be used.

Spiral fin tube is a widely used spiral fin tube. It is a heat dissipation component specially designed to solve the defects of series fins and wrapped fins. Its heat transfer range is several to dozens of times larger than that of bare tubes, which can enhance heat transfer and reduce resistance. Waiting for heat exchange can significantly reduce the loss of metal materials due to the shrinkage of equipment, thereby improving the economy and reliability of heat exchange equipment. The rotor segment high-frequency welding machine uses high-frequency welding processing technology and uses high-frequency power to heat the strip steel and steel pipes to weld them together. It has the characteristics of high heat exchange power, large heat dissipation range, long service life, and wide temperature control standards. It is a new type of heat exchange component with high heat exchange power, large heat dissipation range, long service life, wide temperature range and acceptable working pressure. It is widely used in waste heat recovery, petrochemical industry, power station boilers, economizers, buses, heating, refrigeration, drying, wood drying, grain drying systems and other industries.
