Control of the tube spacing and fin spacing of finned tube heat exchangers

The overall spiral finned tube has good heat transfer efficiency. If compared with other finned tube products, its heat transfer efficiency should be considered high. Compared with the light tube, the overall heat transfer efficiency is about four times higher.

In addition, the entire spiral finned tube is rolled as a whole with the base tube, but other ordinary finned tubes are directly welded to the surface of the base tube. Therefore, thermal resistance is easy and often occurs on the welding joint surface, which seriously affects the heat exchange effect.

Because the overall spiral finned tube is made by rolling with multiple rollers, it has a relatively high smoothness on the surface, and the overall density of the organization is also high. The height between the finned tube and the base tube is relatively natural, so its anti-corrosion performance has been significantly improved.
