Abstract: A condensation enhancement heat transfer pipe that includes an optical pipe section, a fin section, and a transition section connecting the optical pipe section and the fin section. The outer surface of the fin section includes a plurality of individual fins, each having an acute shape of zigzag and forms an angle relative to the axial direction, an axial fin channel forms between the two adjacent ones of said individual fins along the axial direction, a peripheral fin channel forms between the two adjacent ones of said individual fins along the peripheral direction, an end, which is distributed along said axial direction, of each of said individual fins includes platforms, the fin side walls are connected with the platform by an arc, and the platforms are parallel to each other along the peripheral direction.
