Optimized High Frequency Welding Spiral Helix wrapped Fin Tube Heat Exchanger Carbon steel

Product Description

Unlike a plate fin which has multiple tubes going though a common fin,a spiral finned tubes has its own individual fin"wrapped"onto the outside of the tube.This allows the finned tubes to be arranged in any desired pattern,and any X and Y distance apart.A flat strip of material is helically wound on to a tube,much like threads on ascrew,at the desired fins per inch.The finned tube is then cut to the required coil finned length.Each finned tube is [laced inside the coil casing to create the coil's finned face area and rows deep.

Technical Parameters

Spiral Wrapped Fin
FeaturesAdvantages
Each tube is individually finnedIncreased thermal conductivity
