The upper side of the curtain paper 2 is provided with a soaking groove 9, and the lower side is provided with a water receiving groove 10; a plurality of through holes 19 are formed in the bottom wall of the infiltration tank 9, and water in the infiltration tank 9 flows out of the through holes 19 and infiltrates the curtain paper 2. Excessive overflow water on the curtain paper 2 drips or flows into the water receiving tank 10.
A water collector 4 is arranged between the upper heat exchange module 3 and the lower heat exchange module 6, a spray pipe 5 is arranged between the lower heat exchange module 6 and the water collector 4, a plurality of spray heads are arranged on the spray pipe 5, and spray heads spray towards the lower heat exchange module 6; the plurality of spray heads are uniformly distributed over the cross section of the equipment installation cavity.
The bottom of the equipment installation cavity is provided with a water tank 8.

The water outlet pipeline 12 is provided with a water pump 13, and the water pump 13 pumps water in the water tank 8 to the water outlet pipeline 12. The water outlet end of the water outlet pipeline 12 is communicated with the spray pipe 5 to supply water for the spray pipe 5. A second valve body 16 is arranged at the position where the spray pipe 5 is communicated with the water outlet pipeline 12 and is used for controlling the opening or closing of the spray pipe 5. The second valve body 16 may be a butterfly valve.
The water outlet end of the water outlet pipeline 12 is also communicated with a infiltration water supply pipe 17, as shown in fig. 3, a water distribution pipe 18 is arranged in the infiltration tank 9, and the water distribution pipe 18 is communicated with the infiltration water supply pipe 17.
