Copper Finned Tubes

Wire wound fin tube consists of a base tube with oval or near rectangular loops formed of wire which are wound helically over the tube with root soldering of foot of every loop to the tube. - The loop of wire creates greater turbulence thereby increasing the heat transfer coefficient. Root soldering along the entire length eliminates almost all air gaps between the fin and the tube. - For most applications, wire wound fin tubes make it possible to design a much compact heat exchanger coupled with lower pressure drop compared to conventional fin tube.
