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.
In a cooling tower having a housing, a wet deck, a manifold for receiving hot water from a heat source, a plurality of hot-water spray nozzles mounted on said manifold for spraying said hot water on said wet deck, air blower means for blowing air over said wet deck and causing a small portion of said hot water issuing from said spray nozzles to evaporate and remove heat from the remaining water thereby cooling said remaining water by evaporation, and a sump means for collecting said remaining water and returning said remaining water to said heat source, the improvement wherein said spray nozzles include a low pressure fluidic oscillator for:
In a cooling tower having a housing, a manifold for receiving hot water from a heat source, a plurality of hot-water spray nozzles mounted on said manifold for spraying said hot water in said housing, air blower means for blowing air in a predetermined direction in said housing and causing a small portion of said hot water issuing from said spray nozzles to evaporate and remove heat from the remaining water by evaporation thereby cooling said remaining water, and a sump means in said housing for collecting said remaining water cooled by said evaporation and returning said remaining water to said heat source, the improvement wherein said spray nozzles include a low-pressure cusped island oscillator for issuing a sheet of liquid and causing said sheet to:
