Laser welding fin tube is a high-efficiency heat exchange element that tightly connects the fin and the base tube through laser welding technology. It is mainly used in the industrial field to improve the heat exchange efficiency.

Laser welded fin tube is the most technologically advanced product with irreplaceable advantages

1: The base tube thickness can be 0.8-1.5 mm, and the fin thickness can be 0.3-1 mm, which greatly saves material costs compared to other processes.

2: High penetration rate can prevent gap corrosion, extend service life, and reduce heat transfer resistance.

3: Break through material limitations and use different materials for processing.

4: Easy to process secondary processing, coils and bends can be directly processed.

5: The welding heat affected zone is small and the metallographic change is small, making it possible to process small diameter fin tubes.

The materials used for heat exchange tubes and condenser tubes should have excellent heat transfer performance, and should also have good corrosion resistance, erosion resistance, and abrasion resistance. They should also have good strength, stiffness, and plasticity, and be easy to process and manufacture.
