Abstract: A splash bar fill assembly for a splash-type cooling tower includes a plurality of splash bars, each of which includes a one-piece elongated member having a generally convex upper surface of restricted width and also having first and second edges having a pair of converging side surfaces depending downwardly therefrom at an acute angle with respect to the upper surface. The side surfaces of the elongated member are of a restricted depth. The invention includes a means for supporting the splash bar within the cooling tower and an arrangement of successive rows. Each supporting means having a first and second section which intersect at an apex. Adjacent splash bars in the first section are vertically offset in ascending orientation towards the apex. Adjacent splash bars in the second section are vertically offset in descending orientation from the apex.
