UNITED STATES PATENT oFElcEff' JAMES WILSON, OF WEST ALLIS, WISCONSIN, ASSIG'NOR TO ALLIS-CHALMERS MANU FACTURING COMPANY, OF MILWAUKEE, WISCONSIN, A CORPORATION F DELA- WARE.
LIQUID COOLER.
Application led October 2, 1920.
To all whom t may concern.'
Be it known that JAMES WILSON, a citizen of the United States, residing at West Allis, in the county of Milwaukee and State of Wisconsin, has invented a certain new and useful Improved Liquid Cooler, of which the following is a specification.
This invention relates in general to improvements in the art of cooling substances, and relates more speciiically to improvements in the construction and operation of devices for cooling liquid such as oil.
An object of the invention is to provide a cooling device which is simple in construction and eiiicient iii-operation. Another object of the invention is to provide a compact automatic cooler for liquid such as oil.
Some of the more specific objects of the invention are as follows:
To provide an automatic liquid cooling device which is relatively compact in structure and in which the liquid is most eeetively presented to the cooling surfaces.
To provide a cooler which is exceedingly simple in construction' and which may be readily assembled and dismantled.
To provide a cooling device for oil which may be readily inserted in a closed lubricant circulating system, and which is adapted to utilize liquid as a cooling agency.
To provide other improvements in the details of construction and operation of liquid coolers, which will permit manufacture thereof at minimum cost and which will produce maximum efficiency in operation.
A clear conception of an embodiment of the invention and of the operation of the device, may be had by referring' to the drawing accompanying and forming a part of thisspeciiication, in which like reference characters designate the same or similar parts in the various views.
Figure 1 lis a central vertical section through an oil cooler.
Figure 2 is a top view'of the oil cooler.
Figure 3 is a transverse horizontal section through the oil cooler, the section being taken along the line IIIIII of Figure 1 looking in a downward direction.
The cooling device comprises in general an outer tubular casing 2, an inner tubular member 11 mounted centrally within the casing 2, and a pair of helical coiled pipes 9, 10 located within the outer casingl 2 and sur- Serial No. 414,245.
rounding the inner member 1l. The outer casing 2 has its lower extremity closed by means of a screw cap 13 and is provided at its upper extremity witha flange 8 to which a cap plate 4 is detachably secured by means of cap screws 14. The inner tubular member 11 is secured Vto the central portion of the cap plate 4 and extends downwardly within the casing 2. The lower extremity of the inner member 11 is spaced from4 the lower cap 13 of the casing 2. An oil inlet pipe secured to the cover plate 4, communicates with the upper innerportion of the member 11, while an oil discharge pipe 6 secured to the cover plate 4 communicates with the up per end of the space within the casing 2 and surrounding the member 11. The coiled pipes 9, 10 are located within the space between the casing2 and the inner member 11, and are staggered, that is, the inner pipe 9 is disposed within the helical space between the coils of the outer pipe 10. These pipes 9, 10 are assembled by screwing the inner pipe 9 into the outer pipe 10, such assembling being permitted by the formation of the coils with equalV pitch or distance between coils. The lower extremities of the pipes 9, 10 are connected by means of a bent pipe 12, which may be soldered or otherwise detachably connected to the coiled pipes. The upper extremity of the inner pipe 9 communicates with a cooling water pipe 8 which is secured to the cover plate 4. The upper extremity of the pipe 10 communicates with a cooling water pipe 5 which is also connected to the cover plate 4.
lDuring normal operation of the cooler, the oil or `other liquid which is to be cooled is admitted to the interior of the central tubular member 11 through the central inlet pipe 7 and flows downwardly within the tubular member ,11 to the bottom of the casing 2. The heated oil thus admitted then spreads and flows upwardly, in contact with the surfaces of the coiled pipes 9, 10. Cooling water or other agency is admitted through one of the pipes 5, 8 to the interior of the pipes 9, 10, this cooling water being discharged from the other pipe 5, 8. As the oil flows upwardly through the space between the tubular member 12 and the casing 2, it is compelled to assume a circuitous path about and between the staggered coils of the pipes 9, 10, thereby quickly and effectively reducin the temperature of the oil to substantial the, temperature of the cooling agency admittedthiough a pipe 5, 8. Vrlhe cooled oil afterreaching the upper extremity off-'fthe casing 2 is delivered from thecooler` through. the .oildischa-rge pipe 6.
' It Will thus be noted that oil or other fluid admitted through the inlet pipe v7 automatically has its temperature changed .to substantially that of the agency in the coils 9,l 1Q, and isV delivered from the apparatus tljirough'- the` dis `zhargez pipe 6. Due to the Vstaggered arrangement of the coiled pipes 9;, lOithe oil vorfo't'hertiuid treated is forced to flo-vain `direct Contact with practically all portiorfs ,ofgthese coils, thereby utilizingv the cooling changing agency with best efficiency. Itwlill alsdble obvious that the oil'may be admitted'zthrough an opening in the lower caph IBM'and caused to flow directly to the pip/es 9jl0', wi thout necessitating passage throughthe memberrll.
"Thef'icooler may be readily dismantledby releasingthe capscrews 14 whereupon the outenl'casing Qlimay be withdrawn from the pipes 9, l0." Thevpip'es 9, l0 may be discnnected from vthe cover plate a and from the connecting pipe'l, whereupon the inner pipe?) may blef'removedendwise by rotating thesame relatively to the outer pipe l0. vIt
i Willfbenoted that the device may be assembled reversing thesel several operations and that the assembled structure provides a com act Yandihigvhly ejliicient heat transferring Vdevice? VVliile`-thel description refers speciflcallyto the cooling of oilfand to the utilizationof water as a4 coolingfmedium, it
Wilihbe .apparent that other liquids or even gases be either .heated or cooled, or be employed as aheating or cooling medium.
AItshpuld; be understood that it is not desire'd .toV limit .the invention to the exact details-,Of Aconstruction and of operation hereinl shoviin andlvdescribed, for various modificationsV withinT the scope Vof the appended claims may occur toppersons skilled in the l/It.: Y "Itfiselaimed and desired to, secure by Letters P atent: i 'Y .a,cooler, a pairbf` helical tubular vcoilssscrewed one Within theother and haru lnggtheirradJacent: .endspfconnected to 'forni' a Asingle conduit beginning at an end` of onel of said coils and terminatingatthe adjacent end-,ofthe other coil, a cylindrical. ,memberI Y located, Withi-nandj in Yclose proximity to the` innermost; portion Voiusavid coils,l and a tubular casing surrounding and located in close proximity to the outermost portion of said coils.
