Cooling tower
A cooling tower for evaporative cooling of water is contained within an ISO-compliant shipping container frame, permitting stacking of cooling towers for transport and for certain industrial applications. A volume of fill media is contained within the frame. Spaced apart troughs underlie the fill media, running substantially the length of the fill media and connecting to a basin. Baffles are connected to one upper edge of the troughs, while an air flow space is positioned over the other upper trough edge. A water distribution system, with variable flow nozzles positioned closely above the fill media, sprays water over the upper surface of the fill media, where it moves by gravity down into the troughs. Fans atop the fill media move air vertically upward through the fill media.
1. An evaporative cooling tower, comprising:
a volume of fill media for passage of water downward therethrough;
a means for moving air vertically upward through said fill media;
a means for distributing water across an upper surface of said fill media;
a water collection system positioned below said fill media, said water collection system comprising air flow paths therethrough such that air may pass upwardly through said water collection system while water flowing downwardly out of said fill media is collected and flows to a basin, and wherein said water collection system comprises a plurality of spaced apart troughs, one or more of said troughs spanning said cooling tower fill media, each of said troughs comprising a pair of upper edges, one or more of said troughs comprising an angled baffle extending from one of said upper edges, and an air flow space above the other edge, whereby water flowing downwardly from said fill media flows onto said baffle and into said trough, and wherein air flow is through spaces between said troughs and through said air flow space above said edge of said troughs.
2. The evaporative water cooling tower of claim 1 , further comprising louvers disposed in said air flow spaces.
3. The evaporative water cooling tower of claim 1 , further comprising a basin disposed at one end of said troughs, whereby water flows from said troughs into said basin.
4. The cooling tower of claim 3 , wherein said means for moving air vertically upward through said fill media comprises one or more fans positioned above said fill media.
5. The cooling tower of claim 4 , wherein said cooling tower is contained within and mounted within a frame which forms a single ISO compliant shipping container.
6. The cooling tower of claim 5 , further comprising vertically disposed telescoping legs positioned at each corner of said frame, wherein a lower end of each of said legs comprises an ISO compliant corner fitting, and wherein each of said legs may be telescoped to and fixed at a desired length.
