Heat transfer efficiency and smoothness of spiral finned tubes

2022-07-04

The Spiral Finned Tube is very efficient in heat exchange, and to a certain extent, the heat dissipation area is very large, so it can be applied to a wide range of jobs. The Finned Tube has a longer service life, and the spiral finned tube uses the high-frequency power supply as the main heat source.

The spiral finned tube has a very good heat transfer efficiency. If it is compared with other finned tube products, its heat transfer efficiency should be considered high. The efficiency is about four times higher.

For the integral spiral finned tube, the entire fins are integrally rolled with the base tube, but other ordinary Finned Tubes are directly welded to the surface of the base tube. Therefore, on the welded joint surface, The phenomenon of thermal resistance is relatively easy and often occurs, resulting in a serious impact on the effect of heat transfer.

Because the overall helical finned tube is better than the ordinary finned tube in the ability to resist fouling, because of its high-quality performance characteristics, the effect of use has been significantly improved and improved. In the process of production, it is mainly produced by rolling with multiple rollers. It has relatively high smoothness on the surface, and the overall density of the structure is also very high. The gap between the Fin Tube and the base tube is The height is relatively natural, so its anti-corrosion performance has been significantly improved.

The advantage of the spiral finned tube is to increase the heat exchange area with a smaller specific heat capacity, so that the heat exchange efficiency can reach the theoretical maximum value. The area of the finned tube is several times or even 10 times that of the ordinary light tube. At this time, not only the heat exchange efficiency of the equipment is increased, but also the heat exchange cost is greatly reduced.
