FIG. 2 is a schematic structural diagram of a cooling tower of a humidification system of a data center provided in Embodiment 1 of the present application.

As shown in FIG. 2 , the cooling tower 20 of this embodiment utilizes direct contact between dry and cold air and hot water for heat exchange, and then obtains cold water, and at the same time discharges wet air. The air inlet 21 enters the cooling tower 20, and the hot water can enter the cooling tower 20 from the water inlet 22 on the upper part of the cooling tower under the action of the water pump. A water film is formed to increase the contact area between the hot water and the dry and cold air, so as to facilitate sufficient heat exchange between the dry and cold air and the hot water, so that the cold water can be discharged from the water outlet 23 at the bottom of the cooling tower. The moist air is discharged from the air outlet 24 at the top of the cooling tower, and the moist air discharged from the air outlet 24 of the cooling tower is close to saturated moist air, and the water vapor carried in the moist air has reached the standard of distilled water. In the prior art, all the humid air discharged from the air outlet 24 of the cooling tower enters the atmosphere, thereby causing waste of water resources.

Work. Moreover, on the one hand, due to the relatively large air volume delivered by the fresh air blower to the computer room of the data center, the humidification effect of the fresh air blower on the computer room of the data center is better; on the other hand, since the water vapor contained in the humid air has reached the The standard of distilled water, so the humid air will not scale in the fresh air fan and the recovery pipe. At the same time, because the humid air keeps flowing in the recovery pipe and the fresh air fan, and the moisture in the humid air is gaseous, so the fresh air fan is in a state of constant flow. It is not easy for the water to breed bacteria. In addition, the cooling tower in this embodiment may be a cooling tower in the cooling system of the data center, and the fresh air fan may be a fresh air fan in the fresh air system of the data center, so that it is not necessary to equip the data center with a special humidifier and a humidifier for the data center.
