Patented Jan. 20, 1953 LIQUID DISTRIBUTOR FOR COOLING APPARATUS Lawrence R. Obert, Los Angeles, Calif., assignor to Industrial Manufacturers Ltd., Los Angeles, Calif., a corporation of California Application February 24, 1950, Serial N 0. 146,089
8 Claims. (01.257-37) My invention relates to liquid distributors for coolingapparatus and included in the objects of my invention are:
First, to provide in an apparatus of this class, a liquid distributor involving complementary units defining liquid distributor passages and so arranged that the units may be readily separated to expose the walls of said passages so that they may be readily andeiiectively cleaned.
. Second, to provide a liquid distributor wherein said readily separable complementary units may be adjusted relative to each other to regulate the volume of liquid flowing therethrough or may be moved or worked relative to each other to effect cleaning of their confronting walls without actual removal of either unit.
Third, to provide a liquid distributor which directs water or other liquid in thin uniform sheets so as to cause uniform flow around and in intimate heat transferring relation with cooling tubes or the like, disposed coplanarly with said sheets of water, thereby to provide a heat exchanging effect of maximum efficiency.
With the above and other objects in view as may appear hereinafter, reference is made to the accompanying drawings,\in which:
Figure 1 is a perspective view of a cooling tower or heat exchanger involving my invention, one wall of the housing being broken away to illustrate the construction therein.
' Figure 2 is an enlarged vertical sectional view substantially in the plane 2-2 of Figure 1, showing the weir trough and redistributor trough.
. Figure 3 is a fragmentary sectional view through 33 of Figure 2, with portions in elevation.
Figure 4 is a perspective view of the redistributor trough with one end plate separated therefrom.
Figure 5 is a sectional view through 5--5 of Figure 4.
Figure 6 is an enlarged sectional view of the upper or removable grating unit.
Figure 7 is a fragmentary sectional view of the lower or fixed grating unit.
Figure 8 is a fragmentary sectional view similar to Figure 5, showing a modified form of fixed grating unit.
The cooling tower or the like, with which my invention is associated, includes a housing structure I set in a pan or basin 2. Suitably disposed in the side walls of the housing are air intakes 3 and the top of the housing is provided with air outlets or fan stocks 4, in which are mounted suitable fans 5.
system 6 which discharges water over a series.
of grid bafile units I. Above the spray system 6. may be disposed a water separator 8 in the form. of bafiles, for the purpose of minimizing the loss. of water with the discharging air. Below the grid bafile units I is a collector pan 9 having a series of discharge tubes I0 disposed in rows so, as to direct the water into weir troughs I I.. The. weir troughs may be suspended from the collector pan 9 or suitable framework by means of. suspension rods I 2. The weir troughs are shallow and elongated. Their side walls I3 diverge. andare provided with notches [4. Water issuing. laterally through the notches I4 falls. upon fiow directing plates I5 disposed at opposite sides of the weir trough. The flow-directing plates I5 are supported from the weir troughs by pivot mountings I6. The lower extremities of. the flowdirecting plates I5 confront each other to form a discharge-slot, the width of which maybe adjusted'by means of tie-chains II.
Mounted below each weir trough I I so as to receive the water therefrom is a redistributor unit 2|. Each redistributor unit includes side rails 22 connected at their extremities by end plates 23. The side rails are provided with several brace blocks 24 which back sloping side walls 25 extending between the end plates 23. Mounted between the side walls 25 is a lower or .fixed distributor grating 26. This grating comprises a plurality of slots 21 which are diamond-formin cross section and extend lengthwise with respect to the trough. .The slats are supported and secured by cross cleats 28 extending between the side rails 22.
For purposes which will be brought out herein: after, the slats 21 need not in all cases be diamond-shaped as shown in Figures 2, 4, 5 and '7, but may be triangular in form as indicated by 21a in Figure 8.
Fitted within the redistributor trough is an upper or removable distributor grating 29 comprising a plurality of longitudinal .slats 30 of triangular cross section. These slats are disposed with their apexes directed downwardly and are joined together by their upper or base sides by cross cleats 3|. The removable distributor grating is also provided with a longitudinal reinforcing bar 32 having a series of slots 33 in its underside. These are so arranged that a pry member 34 may be inserted from the side, as shown in Figure 5', for the purpose of agitating or removing the distributor grating 29. The slats of the removable distributor grating nestle between the slats of the lower distributor grating to provide therewith pairs of downwardly converging narrow passages for the flow of water. The water issuing from these passages drains particularly in sheet form from the depending apexes of the upper grating slats 30.. The remaining water clings to the sides of the slats 27 and drains likewise in sheet form from the depending apexes thereof.
Mounted below each redistributor unit are a series of heat exchanger tubes 34 arranged in rows which are coplanar with respect to thesheets of water issuing from the apexes of the slats 2'! and 30. With reference to Figure 8,. all of the water drains from the depending apexes of the slats 30. In either case, theheatexchanger-tubes are mounted between suitable headers 35'.
It will be observed that when the upper grating unit is removed, the walls of the passagesdefined between the two grating units are exposed and" can be readily cleaned. This is of primary importance due to-the fact'thatalgae growth tends to clog the passages and needs to be removed from timeto time. Also scum, scale or dirt, deposit on these surfaces; Such clogging interferes with uniform distribution of' the water over the coil sections and reduces the efficiency of heat transfer. It is not always necessary to remove the upper grating. Many times, effective cleaning can be obtained by merely inserting a pry member; asshown in Figure 5,- and agitating or shaking. the upper grating unit.
Having fully described my invention, it is to beun'd'e'rstood that I d'o'not wish to be-limited to the" details herein set forth, but my invention is of the full scope of the appended claims.
