Abstract

The invention relates to an efficient heat exchange fin. The efficient heat exchange fin comprises a base plate. The surface of the base plate is provided with at least two heat exchange pipe holes at intervals and provided with at least two flow disturbing rings at intervals. The efficient heat exchange fin is characterized in that the heat exchange pipe holes are arranged in two rows, the upper row of heat exchange pipe holes and the lower row of heat exchange pipe holes are staggered, the flow disturbing rings are also arranged in two rows, the upper row of flow disturbing rings and the lower row of flow disturbing rings are staggered, each flow disturbing ring is located above the corresponding heat exchange pipe hole, the two side edges of the base plate are each provided with a turnup protruding outwards, the portion, located between the two rows of flow disturbing rings, of each turnup is recessed inwards, so that an energy gathering arc is formed, the portions, corresponding to the energy gathering arcs, of the surface of the base plate are provided with flow guide channels, the flow guide channels are located between the upper flow disturbing rings and the lower flow disturbing rings, a first end opening of each flow guide channel faces the lower row of flow disturbing rings, and a second end opening of each flow guide channel faces the upper row of flow disturbing rings. The efficient heat exchange fin can greatly improve the heat exchange intensity and the heat exchange efficiency.
