[0005] Firstly, especially in the cooling tower with large processing capacity, in order to improve the heat exchange efficiency and rate, the flow rate, the distance between the nozzle and the filler and the sealing structure of the nozzle and the water distribution pipe are adjusted. When the flow rate is too fast, the water pressure in the pipe increases, the distance between the nozzle and the filler decreases, and the sealing structure of the nozzle and the water distribution pipe is not firm. When the flow rate in the pipe is too large for a long time, the nozzle is easily washed away. At this time, the water flow in the pipe will directly impact the lower filler, damage the filler, and also make the water density too large, reducing the heat exchange efficiency.
