A splash bar for mounting to a splash bar hanger in a cooling tower includes a first leg defining a longitudinal axis of the splash bar and openings defined through the first leg. The first leg having an outer surface. The outer surface including surface features thereon. The surface features extending at least one of at an acute angle and generally perpendicularly relative to the longitudinal axis. The surface features designed and configured to promote droplet and cooling medium jet formation during operation of the cooling tower.

A cooling tower splash bar hanger assembly includes a grid comprised of a plurality of wires, including vertical and horizontal wires, defining a plurality of slots. The plurality of vertical wires includes a first vertical wire and a second vertical wire. The plurality of slots includes a first slot. The first slot defines a first slot width. A first splash bar defines a first bar width and is configured for positioning in the first slot supported by one of the plurality of horizontal wires. A second splash bar defines a second bar width. The second splash bar is supported by the one of the plurality of horizontal wires. The first slot width is greater than the first bar width and the second bar width. The first slot width and the first bar width define a size ratio of approximately two to one or greater than two to one.

A filtering cartridge assembly includes: a water collecting tray including a first water supplying hole and a plurality of water draining holes in a bottom wall; a water recovery tray below the water collecting tray, and including a second water supplying hole and a plurality of water recovery holes in a bottom wall; a support frame connected between the water collecting tray and the water recovery tray; a water supplying pipe between the water collecting tray and the water recovery tray, and including first and second orifices communicated with the first and second water supplying holes, respectively; and a plurality of water guiding members in one-to-one correspondence with the plurality of water draining holes, the water guiding member including a first end passing through the corresponding water draining hole and a second end connected to the bottom wall of the water recovery tray.

A hybrid wet/dry cooling tower and novel splash fill material are provided. In one embodiment, the cooling tower includes a wet cooling section having a draft fan disposed above the wet section for drawing air through the wet section to cool liquid traversing the wet section. The cooling tower also includes a dry cooling section disposed laterally adjacent the wet section and configured to enable the draft fan to draw air through the dry section. In another embodiment, the dry cooling section has one or more added draft fan(s) for drawing air through the dry section with or without operation of the draft fan disposed above the wet section. In other embodiments, different structures and configurations of plastic splash fill material are described.
