[0018] A spray pipe 9 is provided on the top of the guide tube 1. One end of the spray pipe 9 is connected to an external cooling water source, and the other end is provided with an annular manifold 8. On the annular manifold 8, there are nozzles 10 that penetrate the guide tube 1 in an equidistant array. The external cooling water source is sprayed on the longitudinal heat dissipation fins 2 through the nozzles 10. The water mist absorbs heat and evaporates. The fan 11 makes the air flow flow along the heat dissipation fins 2, and the hot air containing steam is quickly discharged, thereby further improving the cooling efficiency of the cooling tower.
