The utility model relates to the technical field of heat exchange, and provides a heat exchange fin and a heat exchange structure provided with the heat exchange fin. The heat exchange fin comprises a fin body with an assembly hole, a plurality of protrusions and a plurality of grooves are formed in the two sides of the fin body in the thickness direction respectively, and the protrusions and the grooves are arranged around the axis of the assembly hole at intervals in a staggered mode. Wherein surrounding tracks defined by the protrusions and the grooves are oval around the axis of the assembly hole. According to the heat exchange fin, through the multiple protrusions and the multiple grooves, gas turbulent flow and layering on the peripheral sides of the assembly holes are increased; moreover, the surrounding track defined by the plurality of bulges and the grooves is elliptical, so that a fluid channel with a radian is formed on the peripheral side of the assembly hole; therefore, the air flow can be in fu
