1. A heat exchange fin, with a tube hole formed thereon for a heat exchange tube to be inserted into, and with a corrugated structure arranged near the tube hole, wherein the corrugated structure comprises a wave section arranged along a flow direction of fluid medium, where a distance between two adjacent wave crests or wave troughs of the wave section is one wavelength, and a total length of the wave section is 1-1.5 times the wavelength, and wherein a bridge plate is further arranged at the wave crests and wave troughs of the wave section, respectively, where the bridge plate deflects relative to the wave crests and wave troughs by a preset distance, and wherein the wave section is the total length of corrugation in the corrugated structure.
