A double-open shoulder double-folded fin

Abstract

The application discloses a double-opening-shoulder double-folded-edge fin, and belongs to the technical field of heat exchange equipment, comprising a plurality of fins, the fins are connected with each other through bent circular arcs at wave crests, the end portions of the bent circular arcs at the wave crests on the two sides of the fins are each provided with an opening-shoulder protrusion, and the two sides of the fin are provided with a folded edge structure; the double-opening-shoulder structure of the fin effectively avoids the phenomenon that the fins slide, protrude and the surface of the core is uneven during assembly, increases the strength of the fin, and significantly improves the working performance of the condenser; the double-folded-edge structure better avoids the phenomenon that the fins are laid down, significantly enhances the mechanical vibration resistance of the radiator, and prolongs the service life of the radiator; meanwhile, the double-folded-edge structure can disturb airflow, destroy the boundary layer and enhance the convective heat transfer coefficient; the improved double-opening-shoulder double-folded-edge fin has simple processing technology, simple and convenient assembly, and an assembled core with a smooth and beautiful appearance.
