Principe de fonctionnement

Les laser welded fin tube is made by using a high-energy-density, coherent, and collimated laser beam to join the fin strip and base tube.

Laser welding can produce narrow and deep welds with higher metallurgical bonding and less thermal distortion, ensuring excellent mechanical strength and high thermal conductivity of the fin tube. The welding seams are continuous and super clean, which is ideal for high-performance heat exchanger applications.
