Technical Specification:
- Tube Diameter: Ranges from 0.375 inches to 1.50 inches.
- Wall Thickness: Between 0.035 inches and 0.25 inches.
- Fin Thickness: Varies from 0.010 inches to 0.050 inches.
Definition and Design:
Micro Fin Tubes: These tubes feature small, closely spaced fins wrapped around the tube’s exterior, significantly increasing the surface area available for heat transfer. This design promotes turbulence and improves thermal performance.
Dimensions: Micro fin tubes typically have outer diameters ranging from 0.015 inches to several millimeters, with fin heights from 0.1 mm to 0.25 mm and helix angles between 6° to 30°
What Is Micro Fin Tube?
Micro fin tubes are heat exchanger components designed to enhance heat transfer efficiency, particularly in confined spaces. This is achieved by increasing the surface area through small, closely spaced fins on the tube’s exterior. These fins promote turbulence and improve thermal performance. They are widely used as enhanced surfaces for the benefit of both single-phase and two-phase heat transfer in heat pumps, chillers, and HVAC and refrigerating systems.
Performance Characteristics Of Micro Fin Tube
Heat Transfer Efficiency: Micro fin tubes can achieve heat transfer enhancements of up to 190% compared to smooth tubes in turbulent flow conditions. In laminar flow, the enhancement is about 20%.
Pressure Drop: While micro fin tubes increase heat transfer efficiency, they also result in a higher pressure drop (approximately 1.7 times that of smooth tubes) due to increased friction.
Efficiency Index: The efficiency index indicates that despite the higher pressure drop, the increase in heat transfer is generally superior, especially in turbulent flow.
