Problems in selection and acceptance of laser welded finned tubes

2022-11-14

The fan top Finned Tube is applied to the light radiator, which is made of copper sensitive alloy. Its elastic function is to provide a resultant force for the matching of the radiator and the module shell. This structure is simple in manufacturing and use, but the fin efficiency is low. Therefore, the fan top device is applied to the milliwatt level transistor. Finned Tubes can be designed according to different shapes, such as uniform rectangular straight ribs, triangular straight ribs, trapezoidal straight ribs and concave parabolic straight ribs.

No matter what type of Laser Welded Finned Tube is selected, its surface quality and internal quality shall be strictly checked. Generally speaking, the requirements for its surface quality include that the lath is well processed, the surface quality is uniform, and the coating layer is not allowed to fall off or not covered; The cladding layer shall be closely combined with the core alloy, and there shall be no gap or gap between them. Cracks after multiple bending are not allowed.

Fin Tube

Previous: Laser welded finned tube is a relatively stable product Next: Why is the application efficiency of finned tube high?
