Abstract
A multiple-purpose, non-clogging target-type water distribution nozzle assembly for use in counterflow or crossflow water cooling towers is provided which is sized to safely clear large debris found in some cooling water while giving relatively full coverage water dispersal for enhanced water cooling. The preferred nozzle assembly includes a water metering upper section having a tubular flow conduit for substantially axial, downward water flow. A target is situated below the conduit and includes a central, essentially conical ramp-like element, and a plurality of elongated, outwardly extending, transversely arcuate water-dispersing fingers oriented in a circular array around the base of the ramp-like element. Hot water is initially passed downwardly through the conduit for impingement on the target structure, which serves to create a relatively even dispersal of water over a large area beneath the target, thus enhancing cooling of the water. The target metering section and structure are cooperatively sized and strategically located so as to safely pass relatively large debris found in some cooling waters.
