A typical cooling tower is mainly composed of:
(1) vertical axis fan: the cooling tower is positioned at the top of the cooling tower, and the fan is used for outwards sucking air, so that air outside the tower enters the tower through the air inlet window and is forcibly subjected to heat exchange with cooling water, and the cooling effect is ensured;
