Embedded fin tube‌ is a heat exchange element that directly processes multiple grooves on the surface of the steel tube and embeds the fin structure in these grooves. This design not only increases the heat dissipation area, but also effectively promotes the conduction and dissipation of heat.

Structural features

The structural features of the embedded fin tube include:

‌ Processing method ‌: Usually multiple grooves are directly processed on the surface of the steel tube, and then the fins are embedded in these grooves. This structure allows a larger contact area between the fins and the steel tube, improving the heat dissipation efficiency.

‌ Manufacturing process ‌: During the manufacturing process, the steel strip is embedded in the pre-processed spiral groove and fixed by welding to ensure the tight combination between the fins and the steel tube ‌

Application scenarios of embedded fin tubes

Due to its unique structure and efficient heat dissipation performance, embedded fin tubes are particularly suitable for the following scenarios:

‌ Space-limited occasions ‌: Because it can provide a larger heat dissipation area in a smaller space, embedded fin tubes are often used in computer CPU radiators and other equipment that require efficient heat dissipation but limited space. ‌

‌ Industrial equipment ‌: It is also widely used in industrial equipment that requires efficient heat dissipation, such as power transformers and industrial furnaces. ‌

Advantages and Disadvantages

Advantages of embedded fin tubes include:

‌Efficient heat dissipation‌: By increasing the heat dissipation area and promoting heat conduction, embedded fin tubes can significantly improve heat dissipation efficiency‌.

‌Adaptability‌: With good high temperature and corrosion resistance, it is suitable for various complex working environments‌.

Disadvantages of embedded fin tubes include:

‌Complex manufacturing process‌: Due to its unique manufacturing process, the production cost is high and the production efficiency is low‌

Embedded spiral fin tube manufacturing process

Embedded spiral fin tube is to pre-process a spiral groove of a certain width and depth on the steel tube, and then embed the steel strip on the steel tube on a lathe.

During the winding process, due to a certain pre-tightening force, the steel strip will be tightly tightened in the spiral groove, thereby ensuring a certain contact area between the steel strip and the steel tube. In order to prevent the steel strip from rebounding and falling off, the two ends of the steel strip should be welded to the steel tube. In order to facilitate embedding, there should be a certain side gap between the steel strip and the spiral groove. If the side gap is too small and an interference is formed, the embedding process will be difficult to proceed smoothly.

The wound steel strip will always have a certain rebound, resulting in the steel strip and the bottom surface of the spiral groove not being well joined. Embedded fins can be carried out on general equipment, the cost is not high, but the process is complicated and the production efficiency is low.
