RADIATOR CORE.
This invention relates `to acore for radiators designed more particularly for use in connection with the cooling system of an automobile gas engine and has for its main object the provision of a core for this class of radiators which is strong and durable, which hasla Ylarger radiating capacity and which can be manufactured at comparatively low cost. Y
s This invention is an improvement on the radiator core shown and described in my application for Letters Patent No. 8556 filed February 11, 1925.
In the accompanying drawings Fig. 1, is a front eleva-tion, partly in section of a radiator embodying my improvements.
Fig. 2, is a horizontal sectionV ofthe saine taken on line 2 2, Fig. 1. Y i
Fig. 3, is a fragmentary horizontal section, on an enlarged scale, taken on the line 3 3 of Fig. 1.
Fig. 4, is a fragmentary horizontal section, on an enlarged scale, taken on the line 4 4 Fig. .5, is a fragmentary perspective view Ofone of the radiating plates.
Fig.- 6, is a fragmentary vertical section taken on line 6 6, of Fig. .1.'
Similar characters of reference indicate like parts throughout the several views.'
The numerals 20 and 21 representthe upper and lower kwater boxes or headers which maybe connected with the supply and return pipes of the gas engine cooling system in any suitable and welhknown manner.
Between the headersis arranged the cooling core of thel radiator which consists essentially of a vplurality of upright water i tubes 22 communicating at their upper ends with the bottom of the upper headerand at their lower ends with the top ofthe lower header, and a plurality of horizontal air passages 23, 24 arranged between adjacent water tubes and extending from the front side to the rear side of the radiator.
Each of the water tubes is constructed of a single sheet of metal which is bent to form two upright flat parallel longitudinal walls 25, a rear turn 26 connecting the rearedges Of-said walls, -two inwardly oE-set flanges 19 arranged at the front edges of said walls andk connected together by soldering or Otherwise to form a water tight joint therebetween., and ,horizontal end flanges 27.511.'-
Application filed .Tune 10, 1925. SerialpNO. 36,131.
ranged at the upper and lower ends of the walls and offset flanges and projecting laterally from Opposite sides of the tube.
Y A plurality of tubes of this character are arranged in a transverse row between-the upper and lower headers and spaced suitable distances apart. The upper and Vlower flanges of each tube have their longitudinal .edges connected with the correspondingV edges of the upper and lower flangesy of adjacent water tubes so as to form in eifect a plate at the upper end of the tubes which is secured by soldering or otherwise to the upper header andgcloses the bottom `thereof and a plate at the lower ends of the tubes which is secured by soldering or otherwise -ranged side by side and are connected at one pair of their corresponding longitudinal edges while the yopposite pair of their corresponding longitudinal edges are disconnected but oppose each other. l/Vhen the metal sheet is thus folded each of its corrugated strips forms an inner set of corrugations and an Outer .set of corrugations Yand the suinmits 35 of the inner set of corrugations oppose each other so as to form a vertical row of said airY passages 23 while the outer summits 36 of the'outerset of corrugations are opposed to the corresponding summits of the outer corrugations of spacing L,strips associated with adjacent water tubes V.and lform therewith verticalL vrows of said air passages 2 4.
The central or intermediate parts ofthe i summits 35 ofthe inner setof corrugations Y are odsetvv laterally, as shown at- `Y37, so that Vsuch offsets oncompanion summits 35 together form a tubular seat while, the end 'portions 38 of these summits next to the connecting turn between the two spacing strips and the end portions 39 of these summits yat the disconnected edges of these strips oppose each other in rear and infront of the respectivewater tubes. f V Oneof these water tubes is seated at'intervals throughout its length in the tubular lio seats between the opposing sunnnits ol the inner eoijrugations ioit' the .tufo strips arranged oniopposite sides ot- `this `tube and the latter also traverses the air passages 23 formed between these strips so that the air in passing through said passages will come p in direct contaetwith the portions ot' the tube exposed in said passages and carry away the heat 'which is transmitted to the saule lroni the water passing through the tubes.
The `disoonneeted trout edges oil the tiro `spacing strips associated with each water tube are ipreterably connected by soldering with ithe outer sides oil the longitudinal -l'langesiltl ot Athis tube.
In order to increase the transmission oilE heat to the air, radiating wings, tongues or `bullies `18, "ttl, ttl, l2 `are struelt out of the ybody of the sheet metal forming these strips soithatthe same project laterally `troni these strips into the path ot the a` as the saine passes through the air passages and inten ceptsthe air. For the `purpose ol holding `the several `water tubes and spacing strips in position relative te each other at the rear oit the `core and increasing the strength oit the saine so that it is capable ol" sustaining the shock and strain to which it is subjected while in `use, nieans are provided f'lor eonnecting the opposing spaoingstrips of adjacent Water tubes. This is preferably ae- `eoi'iiplished by providing the rear parts ot the sunnnits "oit the outer eorrugations with lips, Wings `or tongues lla, l5, Which preterably incline in opposite directions, the lips dft in this instance inelining hacltwardly and thelips l5 forwardly, and the lip Llsl on the spacing strip associated with one water tube `interloeking by a Wedging engagement with ithe lip l5 on the spacing strip ot an adjacent water tube, as shown in Figs. 2 and et. `ly this ineans `the rea r parts ot the spacing strips on adjacent tubes are lirnilj,7 drawn against each other and secured together mechanically WithoutI the use ot' solder. These interlocking lips or wings further add to the ballliug oll'eet on the airto induce the latter to absorb the greatest auiount olf heat contained in the water.
In order to still turther increase the `transterenceoit heat- Atrom the water .in the water tubes to the air passing through the air paf sages auxiliary means are provided which are constructed as follows The numeral represents a pluralit)7 oit' `upright radiatinfr strips or `plates oit sheet metalpeaeh of `which `is arranged lengthnWisebetweenthe opposing spacing strips ot' two adjacent water tubes. Each of: these radiating strips is engaged on its opposite et sliythe outer snnnnits 3G of the outer `corrugations of twoopposing spacing strips and is firmly gripped therebetweenso as to produce apgood metallic .Contact therewith and thereby enable the radiating strip toltake soule ol the heat :troni the respective spacing strips and transfer `it to `the air which coines into contact With opposite sides of the respcetiveiradiating strip. i
,lnorder to `permit the locking Wings, lips or tongues et-l, Ll5 on the rearlparts ol the sunnnits o't adjacent spacing strips to engage` with each other, the adjacent reareft oteaeh radiating strip provided with a rertieal row ol clearance openings 5l, through which the inelinedflipstl, 45, project andengage with eaoh other so as to draw the respective spacing `strips by a wedge action against `opposite sides ol the radiating strip, as shown in Figs. l and Ailf. rlflle lips, therefore, not `only interlock `the spacing strips `but also interlock with the radiating strip therebetween and hold the latter against displacement.
`By thus arranging a radiating strip between the outer summits otadjacent eorrugated spaeing stripseaeh air passagoll divided into `two sections land splits fthe s reani nl air `passingtherethrough into jtwo jets which inipinge aganstopposite sides of the `respective radiating strip and thus ncrease the radiation ot heat to the air aceordingly.
For the purpose ol increasing the `heat radiating `capacity ot' the radiating strips each of these strips is provided with a plurality oit Wings or lugs 52 whioh are struck out ot the body ot thisstrip within the air missages A and project laterally therefrom so as to interceiit the streams ol air passing through the core. ""llliese wings or lugs 52 are preferably arranged in longitudinal rows and, the nien'ibers ol each row project alternate-ly troni opposite sides oit `the re spective radiating strip, `asshown in Figs. l Aand 5. These wings or lugs ineach row also in'elerably iu'ojeet alterin'rtely upward ly and downwardly audthus tend to unitorndy obstruct the air iluulisiug through the ,manages Qil. and thereby obtain `the =iua,\: unun radiating eliieieney.
