Wound finned tube refers to a finned tube that is cold-wound and formed at room temperature. Its processing technology is simple and it is convenient to obtain materials. It is formed by directly winding steel or aluminum tape on the steel tube by mechanical force. The rolled finned tube is a kind of finned tube that uses the mechanical force of the roller to reduce the cross-sectional area of ​​the composite tube passing through and increase the length. The string-type process is simple, similar to an air-conditioning heat sink.

Different types of finned tube radiators can be used in different occasions to play a role. At the same time, the prices of different materials and types of products are also different. When choosing a product, users can choose the one that can meet the actual needs.

The finned tube radiator must be provided with a liquid discharge port and an exhaust port. Therefore, the appropriate position and size of the liquid discharge port and the exhaust port must be determined. It may be necessary to provide other holes for installing pressure gauges and thermocouples. The fluid enters and exits the heat exchanger through the nozzles. These nozzles are of equal cross-section and are welded to the shell and the pipe. The size of the pipe must be appropriate, and it should be clear that the pipe bundle will partially block the pores.

When high-speed fluid enters the shell, an impact protection device is required to prevent erosion and vibration of the tube. The forms of impact protection devices include impact plates, anti-shock rods and annular distributors. To decide which fluid to take the shell side and which fluid to take the tube side needs to consider factors such as corrosivity, fouling, cleanability and temperature.
