The invention relates to a novel fin heat exchange pipe which comprises a pipe body with a through hole. Flanges are evenly arranged on the hole wall of an inner hole of the through hole in the circumferential direction. Connectors used for being connected with connecting sheets are arranged at the ends of first fins. One end of each second fin is provided with a round part. The novel fin heat exchange pipe is simple in structure and convenient to use; due to the fact that the flanges are arranged on the inner wall of the pipe body in the circumferential direction, dirt in fluid impacts the flanges, falls and flows out, the heat conducting efficiency of the heat exchange pipe is improved, heat is exchanged evenly on the surfaces of the first fins and the second fins, the heat exchange area is large, and the heat conducting efficiency is high; and in addition, the rhombus connectors are arranged, so that connection and fixing between all fin heat exchange pipes and the connecting sheets are facilitated, the installation stability of the connecting sheets is good, and the round parts are arranged on the end faces of the second fins to improve the safety of the production and manufacturing processes, and scratches are prevented.
