The Finned heating Tube is a metal heat sink wound on the surface of ordinary components. Compared with ordinary elements, the heat dissipation area is expanded by 2.5 to 4 times, that is, the surface power load allowed by the finned elements is 1.5 to 2 times that of ordinary elements. Due to the shortened length of the element, the heat loss of itself is reduced. Under the same power condition, it has the advantages of fast temperature rise, uniform heating, good heat dissipation performance, high thermal efficiency, long service life, small heating device, and low cost. Reasonable design is carried out according to user requirements, which is convenient for installation.
If the thermal conductivity of the two sides of the Laser Welded Finned Tube is relatively different, the fins should be installed on the side with the smaller thermal conductivity to achieve a Stable balance. Therefore, it is necessary to place the side with a small thermal conductivity outside the tube as far as possible during production to facilitate later installation operations. If the thermal conductivity on both sides is not high, only side panels can be assembled on both sides to enhance heat conduction. However, if the structure is limited, fins may not be added, as long as the two sides are balanced. In another case, if the thermal conductivity on both sides of the tube is large, it is not necessary to use finned tubes. Of course, in order to further improve the heat conduction, threaded pipes or corrugated pipes can be used instead of light pipes, and the effect is also very prominent.

Where are Finned Tubes used?
Finned Tube heat exchangers typically use air to cool or heat fluids such as air, water, oil or gas, or they can be used to capture or recover waste heat. These heat exchangers can be used in a wide range of industries including oil and gas, power generation, marine and boilers, nuclear power, marine, military and more
Finned Tubes (finned tube) are mainly Heat Exchanger Tubes used for transferring process heat.
Finned Tubes are essentially tubes with increased surface area. The amount of heat transferred from a particular surface is directly related to the surface area available to transfer heat. Therefore, increasing the heat transfer area as a whole can improve the heat transfer efficiency.
In finned tubes, the surface area of the tubes is increased by providing fins on the heat exchanger. These fins can be of various types, made of various materials, and designed in various ways according to the final requirements.

Finned Tubes are widely used in industries such as power and chemical industry, and many spiral heat exchange surfaces or threaded tubes can be regarded as finned tubes. It has a significant effect on expanding the heat transfer area and promoting turbulent flow, whether it is a single convective heat transfer or a phase change convective heat transfer. The structure of the Finned Tube Heat Exchanger is basically the same as that of the general shell and tube heat exchanger. Just use the finned tube instead of the light tube as the heat transfer surface. Finned tube heat exchangers are also often used to heat or cool the gas outside the tube, and steam or water is passed through the tube, such as air coolers, boiler economizers, radiators, etc.Laser Welded Fin Tube Discount.
The heat exchanger is the key equipment of the thermal system. The Fin Tube heat exchanger is a heat exchanger structure with high technical content and complicated production process. The cold and hot fluids are cross-flowed and exchanged between the walls. The main body of the tube is phase change heat transfer. The tubes are generally arranged in a serpentine shape with multiple tubes. The fins are divided into single, double or multi-row structures. This kind of heat exchanger is widely used in petrochemical, aviation, vehicles, power machinery, air separation, cryogenic, atomic energy, aerospace and other industrial fields. For example, superheaters, economizers, air preheaters, condensers, deaerators, feed water heaters, cooling towers, etc. in boiler thermal systems; hot blast stoves, air or gas preheaters, Waste heat boilers, etc.; evaporators, condensers, regenerators, etc. in refrigeration and low temperature systems; heating and cooling equipment widely used in the petrochemical industry, sugar liquid evaporators and pulp evaporators in the sugar and paper industries, These are numerous examples of applications for heat exchangers.
The advantages of finned tubes are mainly
1. Strong heat transfer capacity: Compared with light tubes, the heat transfer area can be increased by 2-30 times, and the heat transfer coefficient can be increased by 1-2 times.
2. Compact structure: Due to the increased heat transfer area per unit volume, the heat transfer capacity is enhanced. Compared with the light tube under the same heat load, the finned tube heat exchanger has fewer tubes, and the diameter or height of the cylinder can be reduced, because the structure is compact and Easy to set up.
3. More effective and reasonable use of materials: not only because of the compact structure and reduced material consumption, but also it is possible to flexibly select materials for heat transfer and process requirements, such as inlaid or welded finned tubes made of different materials;

4. When the medium is heated, compared with the bare tube, the wall temperature of the finned tube under the same heat load is reduced, which is beneficial to reduce the high temperature corrosion and overtemperature damage of the metal surface.
Regardless of whether the medium is heated or cooled, the heat transfer temperature difference is smaller than that of the bare tube, which is beneficial to reduce fouling on the outer surface of the tube. Another important reason for the reduction of fouling is that the finned tube will not form a uniform overall fouling layer along the circumference or in the axial direction like the smooth tube. Break at the root of the fin, prompting the ridge scale to fall off by itself.
5. For phase conversion heat, the heat transfer coefficient or critical heat flux can be used. The main disadvantages of finned tubes are high cost and large flow resistance. The finned tubes such as air coolers are complex in technology, and their cost reaches 50-60% of the equipment cost; the resistance is large, resulting in large power consumption. However, if the shape is proper, the power consumption can be reduced, which is more cost-effective than the benefit of heat transfer enhancement.
