MANUFACTURING METHOD FOR COIL HEAT EXCHANGER AND FINS FOR COIL HEAT EXCHANGER Russian patent published in 2023 - IPC F28D7/02 F28F9/07 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to a method for manufacturing a coil heat exchanger (1), which contains a central pipe (21) and a tube bundle (2), which contains a plurality of pipes (20), as well as a plurality of fins (6), and the pipes (20) with a plurality of layers (22) of pipes are wound in a helical line around the central pipe (21), and at the same time each fin (6) is located between two layers (22) of pipes so that each fin (6) sets the distance between two layers (22) of pipes, and at the same time, the trajectory of the passage of pipes (20) from the corresponding first pipe grid (104a) around the central pipe (21) to the corresponding second pipe grid (104b) is calculated automatically, and each fin (6) has an identifying feature (400) selected based on the calculated trajectory, which indicates the position of the corresponding fin (6) and/or the position of the pipe (20), and the fin (6) and/or pipe (20) are mounted in accordance with the identifying feature (400). In addition, the invention relates to the fin (6) of the coil heat exchanger (1).

EFFECT: simplification of the manufacture of the heat exchanger.
