Introduction of serrated high frequency welded finned tube High-frequency welding serrated finned tube is to open the teeth of the steel strip before high-frequency welding of the fins, and then use the skin effect of high-frequency current to weld the serrated steel strip to the steel pipe at high temperature. The finned tube produced by [...]
What are the structural characteristics of the Customized Bend Extruded finned tube heat exchanger? Customized Bend Extruded finned tube are used to enhance the boiling heat transfer of the shell-side medium. The base tube is made of ordinary light heat pipe and rolled by rolling process without cutting. The U-shaped finned tube is formed by [...]
The use of heating coils on stainless steel tanks Heating coils can be designed to be installed in new air handling units as gas heating coils or on ducts as duct heaters. When the existing heating system using unit supply air is planned to cancel the central boiler room and become independent gas heating, the [...]
Wide application of finned tube radiators The heat medium (steam or hot water) of the heating system transfers heat to the room mainly by convective heat transfer (convection heat transfer is greater than radiation heat transfer) through the wall of the cooling device. This cooling device is commonly known as a convection radiator. The convection [...]

The higher the fins of the finned tube,the better the heat dissipation The higher the fins of the finned tube, the better the heat dissipation 1. When the heat transfer area of the fins of the finned tube radiator is doubled, the heat transfer coefficient cannot be doubled, but a discount, generally (0.9---0.7), and the [...]
Basic introduction of spiral finned tube Spiral finned tubes have been widely used in heat recovery of boiler economizers, air preheaters and waste heat boilers, as well as heat exchange equipment in various fields such as chemical industry and pressure vessels. The capacity of the unit used in the boiler is also increased from small [...]
What is finned tubes What's the matter with finned tubes A finned tube is a heat exchange element. In order to improve the heat exchange efficiency, fins are usually added on the surface of the heat exchange tube to increase the outer surface area (or inner surface area) of the heat exchange tube, so as to [...]
The advantages of countercurrent heat transfer in finned tube heat exchangers Finned tube heat exchangers's Large logarithmic evaluation temperature difference: The calculation shows that under the same inlet and outlet temperature, the logarithmic average temperature difference in countercurrent flow is always larger than the temperature difference when the two fluids flow together. The larger the [...]
Material of copper finned tube and carbon steel finned tube Classification of carbon steel pipes Hot-rolled carbon steel pipes are divided into general steel pipes, low and medium pressure boiler steel pipes, high pressure boiler steel pipes, alloy steel pipes, stainless steel pipes, petroleum cracking pipes, geological steel pipes and other steel pipes. Cold-rolled (dial) [...]
What is finned tube heat exchanger The finned tube heat exchanger achieves the purpose of enhancing heat transfer coefficient by adding fins to the ordinary base fin tubes, and can have a heating effect. When heating is required, it can use high-temperature water, steam or high-temperature heat transfer oil to heat the air. When cooling [...]
Finned tube working principle and application What principles should we follow when we use finned tubes for heat transfer? (1) If the heat transfer coefficients on both sides of the tube are very different, finned tubes should be installed on the smaller side. (2) If the heat transfer coefficients on both sides of the tube [...]

How to buy the right fin tube? Like the low-fin tube, the medium-height finned tube is a single monolithic tube, made of a single material, but the fin is slightly taller, with a height of 3 mm or 1/3 inch. Of course, higher fin height provides greater surface area and greater heat transfer capacity. Medium [...]
Under normal circumstances, the spacing and height of the finned tube heat exchanger mainly affect the fining ratio, which has a great relationship with the film heat transfer coefficient of the medium inside and outside the tube. If the heat transfer coefficients of the inner and outer films of the tube are quite different, a [...]
