Abstract

A crossflow cooling tower has a number of fill structure sections which are arranged at equally spaced intervals around the entire perimeter of a central plenum that receives generally horizontal currents of air simultaneously from all of the fill structure sections and causes the air to be discharged in an upwardly direction out of the tower. In one embodiment, the tower is provided with four upright fill structure sections disposed in a square arrangement in horizontal view, and a number of the towers may be located adjacent each other in a side-by-side diamond-like arrangement so that each air inlet face of each tower readily communicates with the atmosphere. Both the hot water distribution basin and the cold water distribution basin are formed as integrally molded, one-piece components, and four upright air baffle corner supports carry the weight of adjacent fill structure sections as well as the load presented by the overhead hot water basin, thereby minimizing the need for additional supporting members, bracing or casings to provide necessary structural integrity.

Dependent claims

An induced draft, crossflow cooling tower comprising:

hot water distribution means presenting a horizontal flume for receiving incoming hot water to be cooled and having an outer, upstanding structural water retaining peripheral wall and a floor provided with a central, hot air discharge orifice;
common cold water collection basin means disposed beneath said distribution means;
four spaced upright fill structure sections interposed between said distribution means and said collection basin means for receiving hot water from said distribution means and for enabling gravitational passage of said water to said collection basin means therebelow,
each of said fill structure sections presenting an upright air inlet face for admitting generally horizontal currents of air to a respective section of said fill structure in transverse flow relationship to said hot water gravitating therethrough,
each of said fill structure sections presenting an upright air outlet face for discharging air passing through the respective section,
said fill structure sections being disposed in a rectangular arrangement in horizontal sectional view with a first two of said sections being opposed and spaced from each other and the remaining two sections being located transversely between said first two sections in spaced, opposed relationship to each other,
said air outlet face of each of said fill structure sections being transversely oriented relative to the air outlet face of each adjacent fill structure section,
said air outlet faces facing inwardly of said tower and presenting a common, generally rectilinear plenum centrally disposed between said four fill structure sections for receiving generally horizontal currents of air simultaneously from all four of said fill structure sections and communicating with said orifice in the hot water distribution means;
fan means operable to pull cool air in through the fill structure sections and communicating with said plenum to discharge hot air in an upward direction out of said tower through said orifice in the floor of the hot water distribution means;
and
transversely L-shaped air baffle corner structural supports carried by and extending upwardly from said cold water collection basin means to said hot water distribution means for supporting said hot water distribution means over said fill structure sections, each of said corner supports having a pair of upright, inwardly converging, angle-defining walls serving to carry respective fill structure sections between adjacent pairs of said air baffle supports, and located to substantially block inflow of ambient air between adjacent fill sections, and means joined to each pair of angle-defining walls preventing relative movement therebetween,
said air baffle corner supports, the hot water distribution means and the cold water collection basin means being constructed of corrosion resistant synthetic resin material.
