Why L Type Finned Tubes Are Used in Air Coolers? The core reason for choosing L type finned tubes for air coolers is that their unique structural design effectively solves the problem of low air-side heat transfer efficiency. The specific advantages are as follows: I. Heat Transfer Enhancement Mechanism Increased Heat Transfer Area L type finned [...]
The trapezoidal cross-section formed by rolling L type fin tubes is consistent with the heat flow density distribution. The tube segments are closely combined and the thermal efficiency is high, which prevents the contact thermal resistance of the serial-finned fin tubes due to the inability to eliminate the gaps between the tube segments. Working temperature: [...]
Differences between L/LL/KL wound fin tubes Base tube outer diameter: 16mm~51mm Fin height: less than 16mm Fin pitch: less than 2.3mm Fin thickness: 0.4~0.6mm Base pipe material: carbon steel, alloy steel, stainless steel, duplex steel Fin material: 1060, 1070, 1100, 6063, 5052 Usage occasions: air cooler, heat exchanger, air heater, economizer L-LL-KL type wound [...]
