Multi-channel coiled copper pipe heat exchanger

The utility model discloses a multi-channel coiled copper pipe heat exchanger, and belongs to the technical field of heat exchanger equipment. The multi-channel copper pipe winding heat exchanger comprises a shell, an upper collecting pipe plate and a lower collecting pipe plate are arranged at the two ends of the shell respectively, a pipe bundle is arranged in the shell, and the pipe bundle comprises a plurality of first finished heat exchange pipes and second finished heat exchange pipes which are wound on a cylinder; and each finished heat exchange tube comprises one outer tube and four inner tubes. The inner pipe in the finished heat exchange pipe firstly penetrates into the outer pipe, and then the outer pipe is shrunk to the required size by adopting a pipe shrinking process, so that the friction damage of the inner wall of the outer copper pipe and the outer wall of the inner copper pipe is avoided, and the influence of the abrasion of the inner wall on the flowing property of a rare medium is avoided
