Application led .Tune 27, 1925. Serial No. 40,111.
The main object of my invention is to proi vide flat spacer or division plates in the air passages of a radiator core withv truss-like projections and V-shaped wings struck out from the plates and projecting into the air passages to increase the turbulence of the air in passing through the core and thus effect better cooling by turning the colder portions of the air against the heated metal.
The invention consists further in the matters hereinafter described and claimed.
In the accompanying drawings- Fig. 1 is a front elevational View of a radiator having a core embodying the features of my invention;
Fig. 2 isan enlarged fragmentary front elevational view of a detail of core struc; ture to be hereinafter described; j
Fig. 8 is a transverse sectional view taken on line 3-3 of Fig. 2;
Fig. t is a vertical sectional view taken on line 4-flof Fig. 3, with the outermost plates of the water passages and spacing strips omitted for the sake of illustration;
Figs. 5 and 6 are perspective views of the spacer plate looking at the opposite sides thereof, respectively; and l Fig. 7 is an elevational view of a detail of construction to be hereinafter described.
The radiator, as indicated in Fig. 1, has an outer casing or shell l, containing a core 2 embodying the features of my invention. The core is of the cellular type and has upper and lower tanks and a plurality of pairs of corrugated sheet metal plates 3, 4 extending vertically between the tanks -and so made and arranged to form zigzag water passages 5, 5 alternated by air passages 6, 6, as in structures of this general character.
The plates 3, i of each pair are oppositely disposed and are arranged to have their corrugations extend into each other, with the corrugated marginal portions of the plates along their longitudinal edges offset and interfitting to space apart the remaining intermediate portions of the plates to providek water passages, between them, as shown in Fig. 3. In practice, the plates 3, 4: of each -pair are integrally joined at one end by making the plates from a single piece -of sheet metal ribbon stock and folding it on itself intermediate its ends after being corrugated to bring the plates into the relation shown,
The several pairs of plates 3,4 are spaced apart to provide the air passages 6, 6 by corrugated strips 7, 7 between and along` the longitudinal edges of these plates, as shown. The corrugations of rthese strips 7 conform to the shape of the corrugations of the plates 3, i and, when made on hexagonal'lines as shown in the drawings, give the front and rear faces of thecore a honeycomb `appearance. The strips 7 are integrally connected with their respective plates at spaced intervals in the length thereof and are folded over on the same in the making, asin lthe Erickson Patent No. 1,233,765, granted July 17,1917.
A vertically disposed fiat sheet metal spacer or division plate `8, made in accord-V ance with my invention, is placed ink each air passage 6 between the plates 8, 4 form` ing the same. This plate 8 is narrower than the depth of the core and lies between the strips 7, 7, the latter holding the plate from displacement from front to rear of the core, as shown in Fig. 3. y i
Each plate 8 is provided with a plurality of truss-like projections 9, 9 preferably arranged in rows lengthwise of the plate and on the same side thereof,as shown in Figs. 5 and 6. Said` projections 9 are preferably formed by shearing the plate 8 along the lengths of the projections at the opposite sides thereof and then pressing the same out ofthe body of the plate to one side and shaping the projections to 'have Hat midportions 10, 10 and inclinedend portions 11, 11. i
` The plate 8 is placed in the air passage between its associated plates 3, et with the projections 9 extending into the corrugations of theplate 1 on the side of the projections and with the inclined'end portions 11, 11 of the projections inv surface contact with the inclined side walls of said corrugations, as shown in Figs. 2 fand 4:. Thus in assem` bling the core, the projections 9,19 readily find their way into the corrugations of thek associated plates t and act to center the flattened, as at 12 in Fig. lt, so that relatively wide contact may be had between these plates for increased heat transference from plate 3 to plate 8.
The projections 9, 9 are vertically disposed and are arranged edgewisc to the general direction ot the air currents passingr through the core, so as to split the air currents and create air turbulence for turning the colder air against the heated Inetal to etiect better cooling.
The plate 8 is also provided with a plurality of outwardly projecting wings 13. 18 struck out troni the plate on opposite sides thereof, as shown. 'these wings are struck ont troni the inetal ot' the plate and are made V-shape in forni as shown, so as to facilitate manufacture of the saine. B v having the wings V-shape, they present inclined surfaces to the air currents passing through the core, and thus serve to increase air turbulence by splitting the air currents and turning the colder portions thereof against the heated nietal. In punching out the projections 9 and also the wings 11?. openings are provided in the plate at the projections and wings. resj'iectively, so as to allow air eurrents to pass through the plate and reach the heated inet-al on opposite sides thereof in addition to creat-ing cross-currents to turther increase air turbulence and thus provide for inore etlicient cooling.
As shown in Figs. 5 and (l. the projections 9 and wings 13 are arranged in rows lengthwise of the plate 8, with the projections 9 ot one row staggered with respect to the projections 9 ot' an adjacent row. The plate has two rows of wings 13 between the two rows of projections 9. and these wings extend ontward troni the side ot the plate S opposite the projections 9. rlhere is also a row of wings 13 between each longitudinal edge of the plate and the adjacent row ot projections 9. There is also a row of wings lll in line with a row ot' projections 9, with the wings and projections alternatingl as shown. These wings extend out from the plate `troni the saine side as the projections 9. Moreover, these wings are laterally aliucd with the projections 9 oi the opposite row. while the other projections are laterally alined so at least one ot the projections adjacent the saine.
As shown in Fig. ll.. the wings 13 project into the corrugations ot' the adjacent plates 3, t and are disposed edgewise to the general direction ot the air currents passing through the core for splitting the air currents to increase air turbulence. Moreover, it will be observed in Fig. 2 that certain ot the wings 13 are directly opposite the tlattened portions 12 of the plate 3 and extend outward theretroni toward the plate t with the openings inade in the plates by these wings at the {lattened portions. This of course allows the air to reach the flattened portions, behind the wings to aid in cooling the radiator core.
The details ot structure .shown and described nia): be variously changed and niodi lied without departing l'roni the .spirit and scope ot my invention.
Ars .shown in Figs. 2 and Il. the inidpor tions 1t), 1t) extend across or bridge the corrugationsl in which they are located to split the air currents passing therethrough. The, projections and wings provide iin-,reused nietal surfaces tor contact with .said currents to provide for better cooling. The plates 2l, in their corrugations have bulged portions 14, 14. and 15, the latter beingl larger than the tirst two and between the saine. to interrupt the air currents passing through the core to increase air turliulence. Alter being assembled, solder is applied to the front and rear surfaces along the edges of the strips and plates to close the joints along the water passages and to also connect the parts together.
I claini as my invention:
l. .ln a radiator core, the combination with two spaced apart corrugated plates. of a flat spacer plate between the corrugated plates and having a plurality ot truss-like projections extending into the corrugations ot one ot the corrugated plates and in contact therewith for holding the .spacer plate against. the other corrugated plate, the latter having the crowns of its projections flattened to increase thc arca olE contact with the spacer plate. said spacer plate being provided with a plurality ol V-shaped projections struck out there l'roni and with the openings made in the plate by certain ot the projections opposite said liattened portions.
2. ln a radiator core, the combination with two spaced apart corrugated plates, of a llat spacer plate between the corrugatial plates and haring a multiplicity of truss-like projections struck out il'roni one side of the spacer plate and extending into the corrugations ol' one ot the corrugated plates and in contact with the inclined portions thereof for holding the flat body portion ol the spacer plate against. the crowns ot the corru0 gations otA the other corrugated plate, said spacer plate being provided in its llat body portion with a inultijilicitj' ol' outwardljr projecting Vshaped wings struck out there from and distributed ther-cover. said wings being relatively sinallcr than the trusslilre projections and disposed ojiposite the depressions in the corrugated plates.
