Abstract
This utility model relates to the field of heat exchanger technology and discloses a discontinuous high-low double-helix finned tube heat exchanger, comprising: an inner tube and an outer tube, the inner tube and the outer tube being coaxially sleeved together; multiple fin groups are spirally arranged along the outer wall of the inner tube along the axial direction; the multiple fin groups are arranged at intervals along the spiral line, and each fin group includes alternating spirally arranged first fins and second fins, the first fins and the second fins having a height difference in the radial direction; the bottom of the first fins and the second fins abut against the outer wall of the inner tube, and the top of the first fins abuts against the inner wall of the outer tube; the spiral trajectories of the first fins and the second fins are staggered in the circumferential direction. This utility model provides a discontinuous high-low double-helix finned tube heat exchanger, which can increase heat transfer efficiency and reduce flow resistance.
