ABSTRACT:
A cooling tower having a housing for forming droplets of hot water in an air stream which causes a small portion of the hot water issuing from said oscillating spray nozzles to evaporate and remove heat from the remaining water thereby cooling said remaining water. A sump collects the remaining water and returns the remaining water to the heat source. The low pressure fluidic oscillating nozzles: (a) form large sized droplets of hot water uniformly over a large area, (b) reduce the quantity of droplets of hot water that are less than 2 mm diameter, (c) issue a spray pattern that reduces aerodynamic interference with air flow from said air blower, and (d) reduce sediments getting into the spraying of said hot water. In a preferred embodiment, the fluidic oscillator is a cusped island oscillator having an outlet with diverging sidewalls.
