Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of cooling tower, especially relate to a wind sandproof structure. BACKGROUND

[0002] The working principle of the cooling tower is essentially a process of heat exchange between circulating cooling water and cold air. The cooling tower is provided with an air inlet. The cold air outside the tower enters the tower and contacts with the circulating water to reduce the temperature of the cooling water. Nowadays, the cooling tower is used very frequently. Since the volume of the cooling tower is usually large and the cooling tower is prone to making noise during operation, the cooling tower is usually installed outside the building. On the one hand, the internal space of the building is saved. On the other hand, the influence of the noise of the cooling tower on indoor work is reduced. If the environment where the cooling tower is located is often affected by sand weather, the sand in the air will enter the tower through the air inlet. Over a long period of time, a large amount of sand will accumulate in the cooling tower, causing the packing in the tower to be blocked and seriously affecting the performance of the cooling tower.

[0003] Chinese patent authorization announcement No. CN215003018U discloses a cooling tower wind sandproof structure, which comprises a fixing frame and a protective frame.
