The natural draft or hyperbolic cooling tower is designed to take advantage of the temperature differences between the ambient air and the hotter air inside the tower. The design creates a chimney effect that causes the cold air at the bottom of the tower to push the warmer air out the top.
The natural draft-cooling tower further divided in two types.
Cross flow:-
In a cross flow tower, air is drawn across the falling water. In this design the fill is located outside the tower.
Counter flow:-
The fill is contained within a counter flow tower since the air is drawn up and through the failing water. Design selection depends upon conditions at the particular site.
