The utility model provides a corrugated boss-shaped fin for strengthening heat exchange, which comprises a corrugated substrate and a plurality of fin holes arranged on the corrugated substrate, at least one pair of boss structures are symmetrically arranged on two sides of each fin hole, and the boss structures are arranged on two sides of the fin holes, so that when air flows through a fin heatexchanger, the fin heat exchanger can be used for heat exchange. Due to the existence of the boss structure, a boundary layer on the air side can be damaged, disturbance is enhanced, the air turbulence is improved, the effect of enhancing heat exchange is achieved, the contact area between the fin and air can be increased after the boss structure is additionally arranged on the corrugated fin, theheat transfer area is increased, and therefore the heat exchange performance of the heat exchanger is improved; after the boss structures are additionally arranged on the two sides of the fin hole, the strength of the corruga
