Lord Fin Tube-What is fin tube heat exchanger?

Fin tube heat exchanger is a heat exchanger consisting of finned tube (also known as finned pipe) with supporting structure and shell. Finned tube is the main heat exchanger. Finned tube is composed of base tube and fin. The combination mode includes expansion joint, high-frequency welding, laser welding and so on. Tube-fin heat exchanger is one of the most efficient heat exchangers. It is widely used in many fields, such as power, refrigeration and heating, chemical industry, medicine, food and beverage. Compared with traditional heat exchangers, tube fin heat exchangers have the following characteristics:

1, the heat transfer area is greatly increased, which is 2-10 times higher than the heat transfer area of the light pipe, and it is more efficient and energy saving.

2, it can promote the formation of fluid turbulence, and the heat transfer coefficient is 1-2 times higher than that of the light tube.

3, compact structure, reduce consumption of metal materials, less space and space.

4, the fins can be different from the base materials, and the selection and utilization of materials are more reasonable and economical.

5, long service life, no string liquid, low maintenance cost.
