What is edge tension fin tubes?
Edge tension fin tubes, also known as tension-wound fin tubes or wrap-on fin tubes, are a type of finned tube used in heat exchangers. They are characterized by their unique fin attachment method, which involves wrapping a thin strip of metal around the outside of the tube and then tensioning it against the tube.
The fins are typically made from aluminum or copper and are wound around the tube at a slight angle to create a helical pattern. The fin strip is wound around the tube under tension, which ensures a tight fit and good heat transfer efficiency.
Edge tension fin tubes are commonly used in air-cooled heat exchangers, where they provide a high heat transfer coefficient and good resistance to fouling. They are also used in applications where the fluid being heated or cooled contains particulate matter, as the helical fins help to prevent clogging and reduce the need for maintenance.
Compared to other types of finned tubes, edge tension fin tubes offer several advantages, including a high surface area for heat transfer, good resistance to corrosion, and low pressure drop. However, they can be more expensive to manufacture than other types of finned tubes, which may limit their use in certain applications.
