What is finned tubes

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

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

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

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

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 [...]

Stainless steel fin tube features and application

Processing technology and temperature change of stainless steel finned tube Stainless steel finned tube is mainly used in production process of 304 type stainless steel processing, when making use of it is mainly used for two kinds of medium of heat transfer, laser welding stainless steel finned tube sophisticated technology, excellent performance, is the boiler, [...]

How to buy the right fin 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 [...]

Selection of tube spacing and fin spacing of finned tube heat exchanger

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 [...]

U bending tube heat exchanger basic features

U bending tube heat exchanger basic features U-bending tube heat exchanger is a kind of shell-and-tube heat exchanger, which is composed of tube sheets, shells, tube bundles and other parts. In the case of the same diameter, the U bend tube heat exchanger has the largest heat exchange area; it has simple structure, compactness, high sealing performance, [...]
