Abstract
A counterflow cooling tower (10) is provided having specially designed inlets (14, 16) which minimize turbulence and air flow disruption at the inlet region of the tower (10), thereby increasing cooling efficiency. The tower (10) preferably includes a casing (12) presenting sidewalls (28, 30) each having a lower edge (14a, 16a) which defines the upper margins of the inlets (14, 16). The tower fill structure (20) presents, adjacent each inlet (14, 16) a relieved air entrance face (44, 46) which extends at an angle both downwardly and inwardly from the adjacent casing wall edge (14a, 16a); in addition, the fill structure (20) includes a generally horizontal bottom surface (48) inboard of and below the edges (14a, 16a). A substantially unrestricted, fill-free air flow zone (51) extends between the inlets (14, 16) and between the fill bottom surface (48) and the tower cold water collection basin (22). Comparative tests demonstrate that the inlet arrangement of the invention lowers turbulence and air flow disruption inboard of the inlets (14, 16).
