1. A cooling tower comprising: an enclosure without internal structural support for the enclosure; said enclosure comprising a factory assemblage metal housing having a peripheral wall and an open top and bottom; an evaporative cooling media in said enclosure; liquid distribution means located above said evaporative cooling media for distributing a liquid on said evaporative cooling media so that said liquid gravitates downwardly through said evaporative cooling media; a water collection means in said enclosure below the evaporative cooling media including a plurality of layers of liquid collecting troughs for collecting substantially all of the liquid falling from said evaporative cooling media, said troughs in each of said layers being laterally offset from the troughs in layers of troughs above or below it; and said water collection means being formed of a relatively rigid structural material in the overall shape of a beam having opposed ends, with said ends being connected to said enclosure to provide internal structural support to the enclosure; and said troughs each having at least one open end extending through the enclosure; fan means located below said water collection means for blowing air upward through the evaporative cooling media thereby to cool said liquid; and a vertically extending liquid collecting tank means adjacent said enclosure, said tank means having an opening therein adjacent said at least one end of said troughs for receiving said liquid directly from said troughs.
