Wire Wound Fin Tubes

A copper wire loop configuration delivers 7% to 8% higher heat transfer performance compared to an 11 FPI copper L-Fin tube, while cutting total weight by roughly 20%. Since raw copper is cost-intensive, wire wound loops give a lighter, highly efficient alternative to solid ribbon copper fins without sacrificing thermal transfer.

The continuous loop design lets air and process gases flow around the wire matrix instead of striking a solid surface. This creates localized air-side turbulence — boosting thermal transfer 2 to 3 times over smooth strip fins while keeping overall air-side pressure drop and fan power consumption significantly lower.

Yes. For low-velocity or viscous fluid applications inside the tube, such as lube oil or heavy hydraulic fluids, internal wire turbulators can be soldered inside the bore. Pairing internal turbulators with external wire-wound fins increases overall heat transfer rates by up to 3 to 10 times compared to plain tube bundles.

Because the wire loops are mechanically tension-wound and continuously root-soldered along the full tube length, the joint bond resists vibration levels up to 7G. This makes wire wound fin tubes well suited to heavy industrial compressor coolers and engine-mounted radiator assemblies, where standard tension-wound L-Fins can loosen over time.

The open matrix loop design resists light particulate fouling. When cleaning is needed, low-pressure compressed air blowing, soft chemical bath soaking, or a gentle low-pressure wash-down across the wire axis is recommended. Avoid high-pressure water jetting directly perpendicular to the wire loops, as it can bend the loop profiles.

Aluminium wire is generally not recommended for wire-wound fin configurations, because aluminium cannot be reliably soft-soldered or silver-soldered to steel or copper base tubes at production scale. Aluminium fins work best in extruded or G-type embedded fin configurations. For wire-wound construction, copper, stainless steel, and galvanised carbon steel wire provide the most durable bonds.
