The top of the tower body 1 and below the filter screen 8 are provided with a fan 19, which is used to drive the air flow to circulate through the rotation of the fan 19. One side of the tower body 1 is provided with a water inlet joint 5 and a water outlet joint 6, the water inlet joint 5 is located above the water outlet joint 6, and one end of the water outlet joint 6 extends into the bottom of the water reservoir 7.

Specifically, when the equipment is working, the outside air is sucked into the interior of the tower body 1 through the filter screen 8 by the rotation of the fan 19, and is connected to the hot water pipe through the water inlet joint 5. The hot water enters the interior of the water sprinkling trough 16 through the water inlet joint 5, and then is sprinkled out through the water sprinkling holes 17, thereby increasing the contact area between the hot water and the air, thereby improving the efficiency of the hot water cooling, and it has the characteristics of simple structure and long service life;

[0031] After long-term use, when the filter 8 needs to be cleaned, the driving mechanism drives the cleaning brush 15 to move on the surface of the filter 8, so as to clean the dust adsorbed on the surface of the filter 8, and the fan 19 is reversed to drive the air flow to blow toward the filter 8, so that the dust swept by the cleaning brush 15 is blown out of the device, thereby avoiding clogging of the filter 8 and prolonging the service life of the device;

[0032] The driving mechanism includes a driving plate 14 fixed on the top of the cleaning brush 15. A threaded rod 10 is rotatably connected to the top of the tower body 1 and located above the filter screen 8. The threaded rod 10 is threadedly connected to the driving plate 14. A first motor 11 is fixed to the outside of the tower body 1. The output end of the first motor 11 is fixed to the threaded rod 10. Specifically, the threaded rod 10 is driven to rotate by the first motor 11. When the threaded rod 10 rotates, the driving plate 14 is driven to move. When the driving plate 14 moves, it drives the cleaning brush 15 to clean the surface of the fixed frame 18, thereby cleaning the dust adsorbed on the surface of the fixed frame 18.

[0040] Technical principle: When the equipment is working, the fan 19 rotates to suck the outside air into the tower body 1 through the filter 8, and is connected to the hot water pipe through the water inlet joint 5. The hot water enters the inside of the sprinkler 16 through the water inlet joint 5, and then is sprinkled out through the sprinkler hole 17, thereby increasing the contact area between the hot water and the air, and thus improving the efficiency of hot water cooling. When the filter 8 needs to be cleaned, the first motor 11 drives the threaded rod 10 to rotate, and the threaded rod 10 drives the driving plate 14 to move when rotating. The driving plate 14 drives the cleaning brush 15 to clean the surface of the fixed frame 18 when moving, thereby cleaning the dust adsorbed on the surface of the fixed frame 18, and by reversing the fan 19, the airflow is driven to blow to the filter 8, so that the dust swept by the cleaning brush 15 is blown out of the outside of the equipment to avoid clogging of the filter 8.
