Description

Technical Field

[0001] The utility model relates to the technical field of cooling tower equipment, in particular to an air inlet grille of a cooling tower. Background Art

[0002] A cooling tower is a device that uses water as a circulating coolant to absorb heat from the system and discharge it into the atmosphere to reduce the water temperature. It is currently a widely used heat dissipation device. The side of the cooling tower body usually needs to be equipped with an air inlet grille. The grille can block some foreign matter from entering the cooling tower while meeting the normal ventilation and heat dissipation requirements of the cooling tower, thereby preventing the circulating water in the cooling tower from being contaminated and ensuring the cleanliness of the cooling tower.

[0003] Most of the existing cooling tower grilles adopt a parallel leaf fence structure, that is, multiple parallel blades are vertically arranged inside the grille frame, and the distance between the blades is reduced to block foreign objects. However, this type of structure has a poor light blocking effect. During the use of some cooling towers, due to the need for ventilation, some prokaryotes (such as algae) will inevitably enter the interior due to special circumstances. At this time, if the amount of sunlight entering the cooling tower is large, the algae in the water in the cooling tower will grow faster, causing it to be distributed in large quantities in the water inside the cooling tower, seriously affecting the heat dissipation performance of the cooling tower. At the same time, the irradiation of sunlight will also accelerate the growth of bacteria and affect the cleanliness of the internal water source. In addition, most cooling towers are set outdoors. When encountering some rainy weather, a part of the splashing liquid on the outside is easy to fall into the cooling tower, which may cause the circulating water in the cooling tower to be polluted, affecting the normal operation of the cooling tower.
