fb all whom t may concern.'
Be it known that L'CHARLES SONNEBORN, a resident of Test Pittsburgh, in the county of Allegheny and State of have invented a new and useful Improvement inHeatRadiators, of which the -following is a specication. y
This invention relates to 'heat radiators, and more particularly to heat radiators designed for use as transformer coolers.
' The coils of large electrical transformers are usually immersed in a bath of oil to prevent short circuits and, by radiating to the atmosphere the heat generated in the trans.
former, to also protect the coils from injury. The object of this invention is to provide a cheap and eilicient form of cooler, one which can compete With prior coolers built up of ordinary pipe and pipe fittings or other prior devices; one which is of light Weight7 is entirely leakproof and has a lesser number ofjoints or connections than prior coolers of this class; and one lwhich can be operated with a proportionately small quantity of oil bath and is constructed to provide a large exposed surface area with thin columns of liquid so that the heat of the oil is quickly, thoroughly and cfiiciently radiated to the air. Further objects of the invention are in part obvious and in part will appear more in detail hereinafter. A The invention comprises the construction and arrangement of parts hereinafter described and claimed.
In the drawings, Figure l represents a sectional elevation of one form of cooler enibodying the invention; Fig. 2 is a plan view thereof; Fig. 3 is a detail elevation, partly in section, and on a larger scale, of one of the radiator sections or units; Fig. 4 is a delet in Fig. 3; Fig. 5
Figs. 6 and 7 are detail sectional views, of hea/ler section.
The cooler shown in the drawings comprises a tank-or reservoir 1 containing the oil bath,which is maintained at a level indicated by the dotted line Af-A. This tank is provided with a ledge or series of projections 2 near its upper end serving as supports for the primary and secondary coils of a ltransformer shown in dotted lines at'3, and
Pennsylvania,
on the line 5-5, Fig. 3; and v or sections 5, which are of special form and i construction, enabling them to 'be made-and assembled with the tank at 10W cost, and which also are of light weight, have maximumf efficiency and are substantially leakproo The reservoir 1 is provided near its top and bottom with two series of openings 6 arranged in pairs vertically alined, one of said radiator units or sectionscommunicating at itsheader ends with the alined openings oi a pair. f y
Each radiator unit or section comprises a plurality of hollow cast metal header sections 7 and a plurality of comparatively thin walled rolled or "drawn metal tubes 8 communicating therewith. Each header section is longitudinally of hollow tubular form provided at one end with a boss 9 which may be blank or may be provided with a threaded opening to receive a plug or a pet cock or drain value device 11. At its opposite endl each header section is provided with an internally threaded opening to receive one end of a right andletnipple 12 Whose opposite Aend may be threaded or otherwise secured directly to anzopening 6 of the reservoir but is shown as threaded into a flanged fitting 13 welded or ,brazed 'o the tank Wall around said opening. Preln'ably, also, the threaded connections at both ends of the nipples 12 will be closed or sealed by welding or brazing after assembly to'insure tight joints and absolutely prevent leakage.
Each header section is also provided with a suitable number, three being shown, of lateral openings or hollow bosses 14 to which the ends of the tubes 8 are connected. Said tubes are flattened. or of oval or other thin oblong form to; secure a large exposed surface area with-a minimum overall thickness of radiator unit and to also give a minimum diameter of the liquid column so that the center of the polumn is nearer to the air than in a `mund or other form of tube. The openings or bosses 14 are of similar shape. The tubes are secured to the header lsections preferably by Welding or brazing f so as to secure a perfect seal and guard against leakage or loss 'of oil. Y The header sections may be made of any suitable metal, preferablyy malleablel iron castings, although castings of alloys, aluminum, brass, bronze, or ordinary Cast ironv are suitable. Malleable'iron is preferable, due to its low cost, its homogeneous composition and texture and its usual freedom rom blow-holes. The header,I sections are made as light as possible consistent {With strength,y 5 i lj Figs. 6 and 7 show a modified form of l5 header section having two parallel side Xvalls flarched toward each other along Vone edge, as at l6, to form a roof ori bottom, as the case may be, and goined at their opposite edges to form a straight wall vor `tace 17 are formedA of Wrought iron, and may bey commercially rolled or. ldrawn tubing, seamed or seamless, and attened 'or of oval or oblong form, as'vdescribed.
35 The thin radiator sections, formed as described, are spaced around the periphery' of the oil reservoir, as shown in F ig. 2. Their thin formioverall enables them to be placed forms of radiator,-thereby securing a large "exposed surface area in a small space. The t .much more closely adjacent' than otherl sections are light in Weight and the thin walledtubes largely increased the ability to quickly transmitthe heat. AThe joints are all .tight and the construction is not only strong butalso entirely prevents loss ol oil by leakage. i
`While the invention has been shown applied or use as a transformer cooler it is toybe understood that it is not so restricted but is capable of other uses. For example, the tank or reservoir with the radiator sections applied thereto maybe used for holding and f cooling oil baths for quenching metals during'heat treatment or for cooling other substances than oil. n
1What I claim is l. A heat radiator, comprising a tank or reservoir for containing a liquid r-ud pro vided with two series of openings near its top and bottom, and a series of built-u radiator units 'spaced around said tank, eac unit comprising tWo header sections communicating with openings near the top and bottom of said tank, and metal tubes secured to and connecting said header sections.
2. A heat radiator, comprising a tankl or reservoir for containing a liquid and provided with two series of openings near its top and bottom, vand a series of radiatoinunits spaced around said tank, each unit compris,n ing two header sections communicating with openings near the top and vbottom of said tank, and a plurality of metal 'tubes Vot oblong cross section welded or brazed to said header sections.
In testimony whereof, I have hereunto set my hand.
