Lord Fin Tube--Embedded spiral fin tubes

What is embedded spiral fin tube?

Embedded spiral fin tubes are a type of heat exchanger tube that has a spiral fin attached to its outer surface. The fin increases the heat transfer area of the tube, thus improving its overall heat transfer efficiency.

How to manufacture embedded spiral fin tube?

The embedded spiral fin tube is a spiral groove with a certain width and depth in the steel tube, and the aluminum or copper strip is embedded in the steel tube. In the winding process, because of certain pre tightening force, strip will tightly buckled in the spiral groove, thus ensuring the strip and tube between the contact area. In order to prevent the rebound of the steel strip, the two ends of the steel to be welded on the steel tube. In order to facilitate the mosaic, there should be a certain gap between the steel strip and the spiral groove. If the side gap is too small, the formation of a surplus, the mosaic process is difficult to proceed smoothly. In addition, the winding of the steel belt will always have a certain rebound, the results of the steel strip and spiral groove bottom surface can not be a good joint. Mosaic fins can be carried out in general equipment.

These types of tubes are commonly used in applications where heat transfer is critical, such as in power generation, chemical processing, and HVAC systems. They are also commonly used in air-cooled heat exchangers, where the fins increase the surface area for heat dissipation to the surrounding air.

Embedded spiral fin tubes can be made from a variety of materials, including copper, aluminum, and stainless steel, depending on the specific application requirements. The fin itself is typically made from a thin strip of the same material as the tube, which is spirally wound around the tube and then brazed or welded in place.

Overall, embedded spiral fin tubes are a highly effective and efficient solution for heat transfer applications where space and weight are at a premium, or where air-cooling is required.
