Cooling towers are equipment devices commonly used to dissipate heat from power generation units, water-cooled refrigeration, air ... WebOne particularly effective type of natural draft cooling tower is the hyperbolic cooling tower. These cooling towers use a chimney-stacking design to let the dry, cool outside air push the warm, moist air. The bottom of the tower contains splash fill, and the cool air moving upward cools the water spraying over it. WebA cooling tower is a device that rejects waste heat to the atmosphere through the cooling of a coolant stream, usually a water stream, to a lower temperature.
