1 Claim.
This invention relates to air coolers and the "like and more particularly to air coolers and moisture separators adapted for use as aftercoolers in conjunction with air compressors.
It is well known that :the e iciency of compressed air systemslcanbe increased y employing .so-called aftercoolers between thecompressors and the receivers oraccumu ators in which the air .is stored. 'Heretofore, aftercoolers have comprised bundles of bare tubes through which ;co1d .water-iscirculatedand over which the air to be cooled is caused to how; these devices, hoy ever, are bulky and expensive. Cooling the air also :results in the conden t on f som f the moisture carried by it, and ordinarily it has been necessary to employ separators between the-con- :ventional coolers and the reservoirs in order to remove entrained moisture from the air.
A general object-of thepresentinventionis the provisionlof an air cooler, particularly adapted 11"01' use as an aftercooler, which is compact and efficient and relatively inexpensive to manufacture and install. Another object is to provide an ,airqcooler which also is capable of acting as a separator to remove condensed moisture from the air passing through .it. Another object is the provision of anlair cooler which can be installed readily in an air line extending between a compressor and a receiver. A furtherobiect is the provisionof sucha deviceinwhich the connections for the cooling fiuidare independent of the air connections so that the cooling fluidconnections can-be broken and the-,coolingelements removed for servicing without disconnecting or disturbing the connections between the cooler telements adaptedito-be used with'aftercoole sof the I type. shown in Figure 1; Figuregfi ,is,a {longitudinal sectional view of a .modified .form .of taftercoolerembodying apluralityoi finned lube cooling elements; and Figure 7 is a transverse sectio n ttasen along line 71-11 of Figure 26,
Referring particularly to Figures 1, 2 and 3 of the drawings, my aftercooler is adapted to be connected between a section ill of an air line leading from the air compressor, for example, and another section i i leading to a receiver or accumulator. Boththe compressor and receiver may be of any conventional construction and are not illustrated herein. The two sections Ill and l l of the air line are spacedapart andarelcustomarily disposed in alignment with their axes substantially horizontal. These sections are provided with suitable connections such as the flanges 1:2 andli, respectively, to which my aftercooler, indicated in general at [5, is connected.
.- Thus, myaftercooleris adapted to be interposed between two spaced aligned substantially horizontal sections of an airline.
A preferred form of .my aftercooler comprises a shell tube having a flange ,l atthe inlet end thereof whichis connected to the air line section iii, a suitable gasket beinginterposed betweenthe flanges l2 and I]. The end portion l8 of the shell tube It is angularly related to the axis of the main portion of the shell tube so-that when the bolts ,IQ connectingthe flanges t2 and l? are drawnup, the axis of the shell tube [6 will slope downwardly at-a slight angle to the horizontal as shown, thus disposing the discharge end 2!] andflange -21 of the shell tube adjacentbut be- ,neath-theflanged end [3 of the section I. Thus, the intake end of the shell tube is connected directly to the section ll] of the air line while the dischargeend of the shell tube isofifset slightly beneath the end-of the section II of the air line with the shell tube extending obliquely with respect to'the sections of. the air line.
In orderto connect the shell tubewith section .II of the line, an elbow v25 is welded into the opening 2fiin-theupper portion of the wall of the .shell tube adjacent the discharge end thereof;
the other endof the elbow 25 is provided with a flang 2.! which .is bolted or otherwise suitably ,shell tubetfrom section Hi can return to the air :line through the elbow-25.
In order to cool the air passing through the shell tube, I preferably employ a longitudinally extending tubefiil extending from the discharge .end of the shell tube to a point adjacent the inlet end of the shell tube. The tube 310' is pro- .yided withga pluralityof longitudinally extendingexternal fins 3| thereon, the fins preferably Adjacent the discharge end of the shell tube,
the finned tube is supported by a plate 33; the finned tube is welded into an'aperture in the plate, the plate being bolted to the flange 2| of the shell tube as shown and making a leakproof connection therewith. Thus, the plate closes off the space surrounding the tube 30 within the shell tube 16, and air entering the inlet end of the shell tube can only flow out of the shell tube through the opening 26 into the elbow 25. Additional support for the finned tube may be furnished either by engagement of the fins 3! with the interior of the shell tube, or by appropriate supports (not shown) which may be of any suitable design.
In order to cool the tube at, and by conduction to cool the fins 3|, cold water or other cooling fluid is supplied to the interior of the fin -tube 39 by means of the open ended tube 34 which extends from the discharge end of the shell tube to a point adjacent the closed end 35 of the tube 30 as shown in the right-hand portion of Figure 1. Tube 34 is supported adjacent the discharge end of the cooler in an opening 31 in housing 38 which is welded or otherwise suitably joined to plate 33. Coolant is supplied to the interior of tube 34 by supply tube 39. In order to make a leak-proof connection between the housing and the exteriors of the tubes 34 and 39, pipe threads, as shown, or other convenient means may be employed. Tube 39 is provided with a suitable control such as valve 46 for governing the flow of coolant into the interior of the finned tube 30; the coolant discharged from the end of tube 34 flows back within tube 36 out the open end 4i thereof into the housing 38 and is finally discharged through the discharge conduit 42, valve 43 being provided to control the rate of discharge. One or more spacers 44 may be employed to support and center the tube 34 within the tube 30.
In operation, the tube 30 and the fins 3! are cooled by water or other coolant flowing within the tube 30. The air flowing through the cooler in the direction of the arrow in Figure l is cooled by contact with the surfaces of the tube and fins, the fins providing an extended heat exchange surface. Cooling is thus accomplished efficiently with a compact apparatus, and by reason of the cooling, moisture is condensed in the air and on the tube and fin walls. This moisture drips downwardly onto the lower inner surface of the shell tube I5 and flows by gravity, with the assistance of the air flow, toward the lower or discharge end of the shell tube. In order to collect the moisture, I preferably provide a sump 45 connected to the lower portion of the shell tube adjacent the discharge end thereof, the sump being provided with a discharge conduit 46 and a valve 41 so that condensation may be periodically discharged therefrom.
It is to be noted that the fins 3| terminate in advance of the discharge opening 26 leading to the elbow 25; thus air flowing trough the shell tube can readily enter the elbow 25. Also, the elbow 25 is connected to the discharge opening 26 at right angles to the flow of air through the shell tube; the air flowing from the shell tube into the elbow 25 must make an abrupt turn, resulting in separation of moisture entrained in the air. Thus, the device acts not only as a compact and efficient air cooler, but also functions to separate the condensed moisture from the air passing through it.
In Figures 4 and 5, modified forms of fin tubes are illustrated which are arranged to increase the rate of heat transfer between the air and the fins and to improve the separation of moisture from the air. In Figure 4 the fins 31a extend in a steep spiral along the tube 30, thus increasing the turbulence of fiow of air along the tube, and by the rotary motionof the air, throwing the entrained moisture to the inner walls of the shell tube l6.
In Figure 5 a similar result is obtained by employing a finned tube 3017 wherein the fins 312) are cut into sections as indicated at 50, and the ends of the sections are bent or twisted as shown at 5| to increase the turbulence of the flow of air over the tube and to give it a rotary motion as described in conjunction with Figure 4 to cause entrained air to be thrown out to the inner walls of the shell tube i6.
In the modifications shown in Figures 1 to 5 only a single finned tube is employed. If desired, a plurality of finned tubes may be used; such an arrangement is illustrated in Figures 6 and 7 and is useful in installations where a short aftercooler is required. The general arrangement of the aftercooler of Figures 6 and '7 is identical with that previously described and the same reference characters have been applied to corresponding parts. However, in this form of the invention, the shell tube is of greater diameter than the pipe sections Ill and II, and the connection between the flange i2 of section I0 and the flange Me of the shell tube is made by means of a connecting member 55 having flanges 56 and 51 bolted to the flanges l2 and He, respectively, which member provides for the necessary oblique connection and the change in diameter.
In this modification, the cooling is effected by a plurality of finned tubes 300 which are supported adjacent the discharge end of the shell tube by plate 330 bolted to the flange 210, the tubes 300 preferably being welded to the plate. The finned tubes extend to a point near the inlet 'end of the shell tube and have their ends closed as indicated at 350. These tubes may be supported within the shell tube in any convenient fashion, for example, by the use of spacer bands 58 wrapped around the fins of the tube; these bands function to prevent intermeshing of the fins of the several tubes, but offer substantially no resistance to the longitudinal flow of air.
Coolant is supplied to the interior of the tubes 300 by open ended tubes 34c identical in all material respects with the tubes 34 heretofore described. In this form of the invention, however, the tubes 340 are welded to a plate 59, which is in turn bolted to a flange 60 welded to a short tubular section 6!. The section 6| is welded to the plate 330, and thus the tubular section BI and plate 59 correspond in function to the housing 38 of the previously described modification. Coolant is supplied to the open ended tubes 34:: through a supply pipe 62 controlled by a valve 5 400, and the coolant running out of the open ends of the finned tubes 30c flows into the short tubular section BI and is discharged therefrom through the discharge pipe 42.
While the drawing illustrates three finned tubes within the shell tube I60, it will be obvious that a greater or lesser number may be employed if desired. Also, finned tubes of the character shown in Figures 4 and 5 may be utilized in this modification of the invention.
From the foregoing description of preferred forms of my invention, it will be seen that I have provided a compact and eflicient air cooler particularly adapted for use as an after-cooler in compressed air systems. My air cooler can be manufactured and installed at low cost and acts not only to cool the air but also to separate condensed moisture therefrom, thus in many cases eliminating the need for a moisture separator. Because of the offset arrangement of the air cooler, the bayonet tube or tubes can be removed without disturbing any of the compressed air connections and without interrupting the service of the line. Also, the finned tube or tubes can be removed without disturbing the main compressed air connections between the cooler and the sections I0 and H. Thus, the parts can be cleaned and serviced with a minimum of difliculty. Furthermore, the number of joints for both the air and the cooling liquid are kept at a minimum, and there is substantially no possibility of the cooling liquid leaking into the compressed air stream.
Those skilled in the art will apreciate that various changes and modifications can be made in the invention without departing from the spirit and scope thereof. Accordingly, it is to be understood that my patent is not limited to the preferred forms of the invention described herein or in any manner other than by the scope of the appended claim.
I claim:
