In addition, the upper water curtain 400 is arranged above the upper water tank 100, and the upper water curtain 400 can be wetted by spraying water on the top of the upper water curtain 400, so that part of water in the upper water curtain 400 can be evaporated to absorb heat, and therefore, outside air can be blown out from the air cooler when passing through the upper water curtain 400. In conclusion, the arrangement of the upper water curtain 400 and the lower water curtain 300 can make the air cooler have a better refrigeration effect.

Specifically, referring to fig. 1 and 2 in combination, the header tank 100 includes a bottom plate 110 and a side plate 120; the overflow port 112 is arranged on the bottom plate 110; the side plate 120 is connected to the bottom plate 110 and encloses with the bottom plate 110 to form a cavity structure.

The bottom plate 110 and the side plate 120 enclose a cavity structure, so that the water in the upper water tank 100 can be stored in the cavity. By arranging the overflow port 112 on the bottom plate 110, the water in the upper water tank 100 can vertically fall onto the lower water curtain 300 through the overflow port 112, and a guide pipe is not required to be additionally arranged to guide the water in the upper water tank 100 to the lower water curtain 300.

Of course, in other embodiments, the overflow opening 112 may also be disposed on the side plate 120 of the upper water tank 100, and in order to have a better drainage effect and avoid the water from splashing laterally, a flow guide tube may be installed at the overflow opening 112, and one end of the flow guide tube is connected to the overflow opening 112, and the other end is connected to the lower water curtain 300.

Further, referring to fig. 1 and fig. 2, the top end surface of the lower water curtain 300 has a length direction and a width direction perpendicular to the length direction; at least two overflow ports 112 are provided, and the arrangement direction of the at least two overflow ports 112 is the same as the length direction.

The lower water curtain 300 is generally rectangular, so that the end surface of the top end of the lower water curtain has a length direction and a width direction which are perpendicular to each other, and thus the lower water curtain 300 is conveniently and integrally installed at an air inlet of an air cooler, and the cooling effect of surrounding air is realized. In this embodiment, by providing at least two overflow ports 112, and the arrangement direction of the at least two overflow ports 112 is the same as the length direction of the top end surface of the lower water curtain 300, the overflow range of the water flowing to the lower water curtain 300 at the same time is enlarged after the water flows pass through the at least two overflow ports 112, and the overflow efficiency is further improved.
