Advantages of Laser-welded Finned Tubes Compared To Traditional Finned Tubes

The core advantages of laser-welded finned tubes compared to traditional finned tubes:

High heat exchange efficiency: Laser welding results in extremely low weld thermal resistance (≤0.0005 m²・K/W), far lower than that of expansion joints (0.001-0.003 m²・K/W) and brazing (0.0008-0.002 m²・K/W), leading to smoother heat transfer and a 15%-30% increase in heat exchange efficiency.

Strong weather resistance: The absence of gaps between the fins and the base tube avoids "crack corrosion" (a common problem with traditional expansion joints), and the dense weld seam can withstand high temperatures, high pressures, and vibrations, making it suitable for harsh operating conditions.

Compact structure: Allows for thinner fins (fin thickness ≥0.2mm), resulting in a 20%-40% smaller device volume compared to traditional finned tube heat exchangers for the same heat exchange area.

Typical application scenarios:

Energy sector: Economizers for power plant boilers, air-cooled island radiators, waste heat recovery heat exchangers, suitable for high-temperature flue gas, steam, and other media. Chemical Industry: Acid and alkali solution heat exchangers, reactor jacketed heat exchange tubes, resistant to corrosive fluids and high-pressure conditions.

HVAC Industry: Large central air conditioning condensers, heat pump heat exchangers, utilizing high thermal conductivity to reduce energy consumption.

Transportation Industry: Marine engine coolers, high-speed rail air conditioning heat exchangers, adaptable to vibration and salt spray environments.
