Description

TECHNICAL FIELD

[0001] The application relates to the technical field of cooling towers, in particular to a high-efficiency cooling tower for air conditioning. BACKGROUND

[0002] The air conditioning cooling tower is a device for dissipating waste heat generated in refrigeration air conditioning through evaporation by water and air contact. The upper part of the air conditioning cooling tower is a fan that drives air to flow upward, and the lower part of the fan is a filler layer. A liquid distributor is arranged in the tower. The basic working principle is that dry air enters the cooling tower after being drawn by the fan. High-temperature water molecules with high pressure flow to air with low pressure. Hot and humid water is sprayed into the tower from the liquid distributor. Water droplets and air contact in the filler layer. On the one hand, air and water directly exchange heat. On the other hand, there is a pressure difference between the water vapor surface and the air. Under the action of pressure, evaporation occurs, which takes away the heat in the water, that is, evaporative heat transfer, thereby achieving the purpose of cooling.

[0003] For example, the Chinese patent with the application number CN202210330297.2 discloses an intelligent integrated central air conditioning high-efficiency machine room special cross-flow open cooling tower, which comprises a tower body, a cooling assembly and a constant-pressure water supply assembly. The cooling assembly comprises at least two heat dissipation filler structures, at least two water distribution structures, a fan and a refrigeration host. At least one water distribution structure is arranged above each heat dissipation filler structure. The bottom of the water distribution structure is provided with a plurality of nozzles. The refrigeration host is connected with the bottom of the tower body. The constant-pressure water supply assembly comprises a constant-pressure water tank and at least two constant-pressure water pipes. The constant-pressure water tank and the constant-pressure water pipes are located in the tower body. The constant-pressure water tank is arranged on the inner bottom wall of the tower body. The water distribution structure is connected with the constant-pressure water tank through the constant-pressure water pipe.

[0004] According to the related technology in the above, the inventors believe that there are the following technical defects to be improved:

[0005] Under the action of gravity, the common cooling tower generally directly introduces high-temperature cooling water from a high place. After spraying, the cooling water falls vertically and is then directly discharged. The cooling water has a short contact time with the cold air during the vertical falling process, and the cooling water cannot be fully heat exchanged, so the cooling efficiency is low.
