The outlet of the axial flow fan rotates and rises in the flow field and the special structure of the inverted V-shaped tube bundle, so that the aerodynamic field in the air cooling unit is distributed in a central symmetry manner, a high-flow area and a low-flow area are formed on the surface of each side tube bundle, the flow distribution is extremely uneven, the phenomenon of uneven distribution of the thermal load on the surface of the tube bundle is caused, the utilization rate of a large-scale air cooling heat transfer surface is low, and the efficiency of a heat exchanger is poor. For the whole air-cooled condenser consisting of dozens of air-cooled units, the flow direction of environmental transverse wind is vertical to the axial direction of an axial flow fan, so that the static pressure at the inlet of the fan is reduced, the flow deformation is intensified, particularly, the dynamic performance of the fan at the upstream of a wind field is obviously reduced, and the heat transfer performance of a fin tube bundle of the corresponding air-cooled unit is also sharply deteriorated. The environmental wind kinetic energy is quickly attenuated under the influence of the aerodynamic performance of an upstream fan group, so that the heat dissipation performance of the air-cooled condenser has a strong wind effect action area and a weak wind effect action area and presents an obvious spatial distribution rule, the difference of the flow heat transfer performance of a large-scale air-cooled heat transfer surface is increased, and the efficiency of the heat exchanger is reduced.
