[0026]

[0027] ​When the water flow driving mode is selected, the support liquid inlet 303 and the support liquid outlet 304 are connected to the water pipe system on the cooling tower, so that the water in the water pipe system flows into the support shell 301 from the support liquid inlet 303 and then flows out from the support liquid outlet 304. At this time, the water flowing into the support liquid inlet 303 from the support liquid outlet 304 pushes the driving fan blade 201 to rotate, and the rotation of the driving fan blade 201 drives the driving shaft 202 to rotate. When the driving shaft 202 rotates, the adjusting fan blade 101 arranged on the driving shaft 202 rotates, and the rotation of the adjusting fan blade 101 drives the air flow, so that the air contacts with the water in the cooling tower, the heat in the water is transferred to the air through evaporation and convection, the air carries away the heat, and then the temperature of the water is reduced. This process relies on the pressure of the water flow in the water pipe system to drive the device to work, and realizes energy saving and emission reduction.
