Finned Tube

Finned Tube
The 3D-internal-external finned tubes overcome the problems that other heat transfer enhancement tubes could not solved for long time, including: large pressure loss, single working media, low efficiency in tube internal transfer and low total heat transfer efficiency. Its unique internal and external finned structure greatly increases heat-exchanging area both inside and outside the tube with dramatically increased number of Carmon Eddy Street and reduced thickness of boundary layer.Special features:1. Convection heat exchanging coefficient for single-phase fluid is 2.5 to 6 times higher than that of the plane tube.2. Boiling heat transfer coefficient is 2 to 5 times higher than that of plane tube.3. Condensing heat transfer coefficient is 3 to 6 times higher than that of the plane tube.4. Its machining technology is suitable for almost any metal materials.5. Intelligent tooling design realizes breakthrough in the fin height on the inside and outside surfaces of the tube.6. Optimization design of variable fin height and variable fin density are made possible by using specialized numerical controlled machining equipment.7. Unique self-cleaning feature greatly reduces maintenance cost of heat exchangers.
