Heat Transfer Surfaces

Wire Finned Tube

Wire finned tube is a high efficiency tube consisting of a series of elongated wire loops, spirally wound on to the tube wall and held in position with a binding wire at the base of the loops. The loops and binding wire are then soft soldered to the tube wall to give a metallic bond between the wire fins and the tube.
The loop density and wire diameter can be varied to give the optimum surface for specific heat transfer and pressure drop requirements.
The wire loop secondary surface gives these finned tubes excellent heat transfer characteristics because of its ability to promote turbulence in the fluid passing over it and thereby reducing the tendency for boundary layer formation.
A wide range of both tube and wire materials are available.
Heat transfer performance can be enhanced by utilising SHE’s (or TFL’s) unique internal solder bonded or pulled in secondary surface/turbulator system.
Our Wire Wound fin tube can be incorporated into our own exchangers or alternatively purchased separately from our sister company Tube Fins Ltd.
