Method of manufacturing a heat exchange tube

摘要

A method for the manufacture of an enhanced heat exchange tube, in which the internal surface area is increased by either minimizing the apex angle of internal fins or increasing the fin height. The fins are formed by annealing a metallic strip while inhibiting recrystallization grain growth, texturing metallic strip, deforming the textured metallic strip into a generally circular configuration and bonding opposing edges of the strip together to form a length of tube.
