Air guide well of high-altitude water collection cooling tower and cooling tower thereof

The invention provides an air guide well of a high-altitude water collection cooling tower and a cooling tower thereof. The air guide well comprises a shaft body; the lower end of the shaft body penetrates through a taper hopper pool, and is connected with a foundation; a water shielding cap is arranged at the upper end of the shaft body; cooling air enters through the lower part of the shaft body, and is guided out by the water shielding cap for cooling fillers in the cooling tower; meanwhile, the shaft body and the taper hopper pool achieve a mutual supporting effect to improve the stabilityof the air guide well and the taper hopper pool; secondly, the water shielding cap is arranged at the top of the shaft body to prevent water from entering the shaft body to realize water-vapor separation; and finally, a support column is arranged at the top of the shaft body, and is connected with a filler beam and a dehydrator beam to achieve a supporting effect on the filler beam and the dehydrator beam and to improve
