Laser welded finned tube is an efficient heat exchanger assembly, which is mainly composed of two parts: tube body and fins.

The tube body is usually made of metal materials such as carbon steel, stainless steel or copper, which have good thermal conductivity and mechanical strength. The diameter, wall thickness and length of the tube body are determined according to the application requirements to ensure sufficient fluid flow space and heat exchange efficiency.

The fins are the key part of the laser welded finned tubes, they are usually made of materials such as aluminum, copper or steel and are fixed to the outer surface of the tube body by laser welding technology.

Laser welding technology is widely used in the production of finned tubes due to its advantages of fast welding speed, small heat affected zone, high welding strength and beautiful weld seam.

The fins can be flat, spiral or corrugated in shape and are designed to increase the heat exchange area and improve the heat exchange efficiency.

In the structural design of laser welded finned tubes, the spacing, thickness and height of the fins are carefully calculated to ensure the heat exchange efficiency without adding too much resistance.

The surface treatment of the finned tube is also very important, such as by anodizing, plating or coating to improve its corrosion resistance and heat exchange performance.

Laser welding fin tubes are widely used in air-conditioning, refrigeration, chemical, electric power and automotive industries, and they play an important role in improving heat exchange efficiency, reducing energy consumption and extending equipment life.

Due to their compact structure, high heat exchange efficiency and reliability, laser welded finned tubes have become indispensable components in modern heat exchange systems.
