Abstract
Abstract Liquid-stream control and diffusion structure for each of the apertures in the hot-liquid distributor which overlies the fill assembly of a liquid-cooling tower. Each structure structure is provided with a tubular liquid-metering component adapted to be received in a corresponding aperture and a target below the metering component defined by a generally planar section provided with a series of slots therein partitioning the section into a series of outwardly projecting, individual segments located to divide the stream of hot liquid gravitating onto the target section from the metering component thereabove into an umbrellashaped liquid pattern with spoke defining interior liquid sheets to thereby break up the column of water discharged from the metering component and assure relatively uniform distribution of the liquid over the plan area of the fill assembly therebelow served by that control and diffusion structure.
