Namely, the distance between the orthographic projections of the water bearing columns 121 of the two adjacent rows of water bearing assemblies 12 on the projection plane is greater than or equal to 0. That is, the water receiving columns 121 of two adjacent rows of water receiving assemblies 12 are arranged in a staggered manner in the thickness direction of the fixing frame 11. Therefore, the air flow passing through the two adjacent water bearing columns 121 of the front water bearing assembly 12 can blow towards the water bearing columns 121 of the rear water bearing assembly 12, the water bearing columns 121 of the water bearing assemblies 12 in all rows can be fully contacted with the air flow, a bent air passing channel is constructed, the wind path is increased, the evaporation area is increased, the wind resistance is small, and the wind speed loss can be reduced. Of course, in other embodiments, the orthographic projections of the water bearing columns 121 of two adjacent rows of water bearing assemblies 12 on the projection plane may also be partially overlapped.
For example, referring to fig. 1 to 3, in an embodiment, each of the water receiving columns 121 of the water receiving assembly 12 extends along a width direction (refer to a direction indicated by an arrow Y in fig. 2) of the fixing frame 11, and the water receiving columns 121 of the water receiving assembly 12 are sequentially arranged at intervals in a height direction (refer to a direction indicated by an arrow H in fig. 2) of the fixing frame 11. Specifically, the extending direction of the water receiving column 121 may be parallel to the width direction of the fixing frame 11, or the extending direction of the water receiving column 121 may be inclined with respect to the width direction of the fixing frame 11.

The interval between the uppermost water-bearing column 121 and the water diversion hole 131 in the water-bearing component 12 is greater than or equal to 0.5mm and is less than or equal to 1.5mm, so that water flows out from the lower end of the water diversion hole 131, and when the water diversion hole 131 is not completely separated, water can be in contact with the water-bearing column 121, so that under the action of gravity and water viscosity, the surface of the water-bearing column 121 can be quickly flowed to by water in the water diversion hole 131, and normal water outflow of the water-bearing columns 131 is ensured. Wherein, the distance between the water diversion holes 131 and the water bearing column 121 can be 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1.0mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm or 1.5 mm. Of course, in other embodiments, the distance between the water diversion hole 131 and the water bearing column 121 may also be less than 0.5mm, or greater than 1.5 mm.
Unlike the embodiment in which the water receiving columns 121 of the water receiving assembly 12 extend along the width direction of the fixing frame 11, referring to fig. 4 to 7, in another embodiment, the water receiving columns 121 of the water receiving assembly 12 extend along the height direction (refer to the direction indicated by the arrow H in fig. 4) of the fixing frame 11, the water receiving columns 121 of the water receiving assembly 12 are sequentially arranged at intervals in the width direction (refer to the direction indicated by the arrow Y in fig. 4) of the fixing frame 11, and the water spraying structure 13 is provided with a water distribution hole 131 corresponding to each water receiving column 121. Specifically, the lower end of the water receiving column 121 is connected to the fixing frame 11, the water spraying structure 13 is provided with one water diversion hole 131 corresponding to the upper end of each water receiving column 121, and when water falls from the water diversion hole 131 to the water receiving column 121, the water flows from the upper end to the lower end of the water receiving column 121, so that the water can be covered at each position in the length direction of the water receiving column 121. So will hold a plurality of water columns 121 of water subassembly 12 and all extend along the direction of height of mount 11, and drench that water structure 13 corresponds each and holds water column 121 and all be equipped with when dividing hole 131, can promote each and hold water column 121 surface water film coverage to promote evaporation area.
