Since a plurality of light-shielding plates 12 having water resistance and light-shielding properties are lined up all over the entire peripheral surface of the cooling tower A in a state where the intake passage 11 for the outside airflow is secured, the intake passage 11 is operated during the operation of the cooling tower A. Through the louver 10, the outside airflow is sucked into the main body 13 of the cooling tower A, comes into contact with the cooling water in a countercurrent state, and the cooling water is cooled by the latent heat of vaporization accompanying the evaporation of the cooling water. After being collected in the lower water tank 20 of the tower A, it is supplied to a load unit, for example, a refrigerator. At this time, light rays from the outside, especially sunlight, are shielded by the light shielding plate 12 and do not flow into the lower water tank 20 of the cooling tower A, and in this lower water tank 20, there is no generation of algae due to photosynthesis, Further, the proliferation of bacteria such as Legionella is suppressed. Especially, since the back surface of the light shield plate 12 is black, the light rays are absorbed by this back surface, and the lower water tank 2
It does not reach 0. The light shielding plate 12 also prevents the cooling water from scattering from the lower water tank 20 to the outside. Embodiment 2 This embodiment is a typical embodiment of the invention described in claims 1, 2, 4, 5, 6, 7, and 8 and is claimed in claims 9, 10, 11, and 12.

が、直交流式冷却塔とすることもある。By arranging the light shielding plates 12 in this way,
During operation of the cooling tower A, the light shielding plate 12 is arranged so as to be curved so that the outside airflow is curved from the surface of the louver 10 through the louver 10 through the intake passage 11.
Smoothly flowing toward the louver 10 by using the curved surface of the guide surface as a guide surface, and is sucked into the main body 15 of the cooling tower A,
The cooling water comes into contact with the cooling water in a countercurrent state, and the cooling water is cooled by latent heat of vaporization accompanying evaporation of the cooling water.
After being collected in 0, it is supplied to a load part, for example, a refrigerator. At this time, light rays from the outside, particularly sunlight, are shielded by the light shielding plate 12, do not irradiate the water surface of the lower water tank 20 of the cooling tower A, and in this lower water tank 20, there is no generation of algae due to photosynthesis, Further, the reproduction of bacteria is suppressed. Especially, since the back surface of the light shielding plate 12 is black,
The light rays are absorbed by this back surface, pass through this light shielding plate 12, and do not reach the lower water tank 20. Further, the reflected light of the ground on which the cooling tower A is installed is also absorbed by the black surface of the light shielding plate 12, and almost no light beam from the outside reaches the lower water tank 20. Although the counterflow type cooling tower is described in each embodiment, it may be a crossflow type cooling tower.
