Problems solved by technology

[0004] In the process of continuous optimization, innovation and improvement testing, it was found that the existing patented technology structure has the following deficiencies: (1) The topological layout of the secondary water distribution nozzles is unreasonable, especially the arrangement of the inner ring nozzles is far away from the air inlet, and the resistance loss cannot be maximized Give full play to the ventilation and cooling performance of the secondary spray components; (2) The number and spacing of primary water distribution nozzles are limited when the spraying water density is large, and the interference is enhanced, which reduces the primary ventilation performance and cooling performance; (3) The overall louver at the lower part of the original tower The air inlet structure is easy to cause a short circuit of the primary spraying and ventilation, which reduces the heat exchange efficiency of the cold air, thereby reducing the cooling performance
