About Serrated Fin Tubes

Serrated finned tubes are efficient heat transfer elements widely used in industrial heat exchange equipment. Their unique serrated design enhances both heat transfer efficiency and anti-fouling performance.

Structural Features

Dense arrangement of fins with spacing as small as 0.5mm
Serrated fin pattern creates intense fluid turbulence
Significantly increases heat transfer efficiency

Manufacturing Process

The manufacturing process involves high-frequency welding with local cutting of strip material before winding. During winding, cut parts separate to form the gear-shaped serration pattern, providing:

Simplified winding process with reduced deformation
Tight bonding and high strength
Excellent resistance to thermal and mechanical vibrations
Superior thermal expansion performance
Low flow loss and strong corrosion resistance

Key Advantages

High Heat Transfer Efficiency:

Serrated fins create turbulence for higher film heat transfer coefficient
Heat transfer coefficient of 30-50 kcal/m² for flue gas/water exchange
Increased contact area enhances heat transfer effect

Strong Anti-Fouling Performance:

Serrated design disrupts fluid boundary layer
Reduces ash accumulation and fouling
Improves long-term heat exchanger efficiency

Excellent Mechanical Performance:

High-frequency welding ensures strong fin-to-tube bond
High pressure resistance
Superior mechanical vibration resistance

Applications

Industrial Waste Heat Recovery
Air Conditioning and Refrigeration
Energy Utilization Systems
