AUTOMOBILE RADIATOR, APPLICATION FILED MAR.I5, 1920.

JET/5772407" JULIUS A. HUSSAR, OF CLEVELAND, OHIO.
AUTOMOBILE-RADIATOR.
Application filed March 15, 1920. Serial No. 365,752.
To all whom it may concern:
Be' it known that I, JULIUS A. HussAn, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Automobile-Radiators, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.
An object of my invention is the provision of an automobile radiator that is simple and economical in construction, light in weight and efiicient in use. A more specific object is to provide a radiator that may be constructed of a plurality of identical cellular units, each adapted to be made froma single stamping with one pair of dies.
Each unit of my invention 's made by folding onto itself a corrugated and crimped metal strip. When the units are assembled there are at once provided sets of air passages interspersed with water passages. The side walls of the folded strips thus confine a plurality of'airducts on one side and water passageways on the other, each wall being in contact with the air and water. The
water passageways are so arranged that they act to retard the flow of water without causing clogging, and the water distribution and flow and the heat radiation are uniform throughout the entire radiator body.
Other features and objects will become more apparent as the description proceeds. The essential characteristics of the invention are summarized in'the claims.
A preferred embodiment of my invention is illustrated in the accompanying drawings wherein Figure 1 is a plan of a strip of metal, the proportions of which may be varied as'desired, suitable for the construction of one of the cellular units of the radiator; Fig. 2 is a similar view of the strip after passing through the dies; Fig. 3 is an edge view thereof; Fig. 4 is an end elevationof thestrip of Fig. 3,.bent to form one cellular unit; Fig. 5 is a front view of a radiator constructed from a plurality of cellular units in accordance with my invention; Fi 6 is a vertical section through the intenor of the radiator body, showing the relative arrangement of air and water passage ways, and Fig. 7 is an enlarged sectiontaken on the line 7-7 of Fig. 2. Fig. 8 is a cross section of portions of two adjacent units.
In the drawings, 10 designates a rectangular strip of thin sheet metal of suitable width and length which is struck up in a die to form a peculiarly crimped and corrugated wall, and which when subsequently bent 1nto U-shape and secured in such posit on, constitutes one cellular unit of a radiator. A plurality of such units properly securedtogether and incased in a suitable housing may constitute a complete radiator.
The stamping operation to which the sheet shown in Fig. 1 is subjected, causes the 1ongitudinal central portion to be corrugated as at 11, which necessarily reduces it in length as clearly illustrated in Fig. 2. The dies are so. shaped that the side margins 12 are not corrugated, but a perpendicularly creased or folded portion 14, is formed in each margin, instead, preferably of the same depth but slightly out of alinement with the apex of each depression 15 in the central corrugated surface 11. The portions 13, of
the margins 12, between each fold 14, are I left in the original plane of the sheet which is also occupied by the uppermost elements or apices ofthe PI'OjGCtlOIlS 16, which projections alternate with the depressions 15 {to constitute the corrugated surface 11.
As shown most clearly in Fig. 7,the sides of the depressions 15, and' projections 16,
are preferably of unequal length and slope,
the sides 19 being shorter and therefore steeper than the sides 18. The sides unite however,- in apices constituting fairly sharp plight angles to form the corrugated surace.
Since the sides 18 and 19 of the intermediate corrugated portion 11 of the-strip 10 are planes connected at right angles, the operation of crimping the margins 12 to form the perpendicular creased portions 14-of a depth equal to that of the'depressions 15, increases the length of the marginal portions and necessarily stretches the metal forming them This increase in the combined length of the marginal single portions 13 and folds 14 over that of the walls 18 and 19 of the in-.
termediate corrugations is found to be nearly fifty per cent. By thus stretching the metal of the margins to obtain the greater surface necessary to form the rectangular cellular front and rear faces of the radiator,
course is of two-fold advantage, being desirable in the matter of reducing the initial cost and in the production of a radiator of light weight. The strength of the radiator thus produced moreover remains ample since it will be observed in the finished structure that the marginal portions thus reduced in weight are ofdouble thickness.
The ends of the sheet 10 as stamped after passing through the shaping dies are bent at right angles as shown at 20, which bent portion constitutes one-half of each intermediate folded portion 14. The sheet may be bent back upon itself at the middle fold 14, as shown in Fig. 4, to bring the bent end portions 20, and each pair of folded portions 14 spaced equidistant-1y from the. ends, into abutting engagement. The joints so formed may be secured together as by solder, thus forming a closed cellular unit 25, the perpendicular sheet portions 13 and 14 form} ing a row of rectangular cells 26. By virtue of the offsetting of the folded portions 14,
with respect to the depressions 15, when the former are bent into abutting relation as shown in Fig. 4, the latter are slightly offset as at 28 in Fig. 6, thus providing a continuous zig-zag passageway 29, extending from top to bottom of each unit 25, and opening at front and rear into the cells 26; the cells 26 and passageways 29 constituting air ducts.
It will be seen that units may be formed by placing two of the corrugated strips in facing relation so that the smooth faces of the margin are separated. This construction avoids the necessity of bending over a strip so that the only metal forming operation that would be necessary would be the corrugation of the center portion of the strip and the crimpin of the margins.
In Fig. 5 is illustrated a complete radiator comprising a frame 27, having therein a casing 24, containing a pluralit of the cellular units 25, secured together side by side as b soldering the adjacent walls 13 together. 'llle assembly of cellular units 25 side by side provides zig-zag passageways 30 between the adjacent exterior corrugated surfaces of the units. These passageways are closed at front and rear .by reason of the soldered joints between the walls 13, but open at top and bottom into the casing 24, and constitute water passages, forming a part of the water circulating system of the jacket of the motor, which may be supplied with water through the usual cap 35. j
As shown clearly in Fig. 6 the corrugated walls of each unit 25- are out of engagement,
by reason of the offsetting at 28 between the adjacent depressions 15 of opposite walls. This construction permits of a continuous air passage from top to bottom of the unit, thus entirely separating the water passages 30 formed between the units. This separation of the walls of the water passages at tral longitudinal portion all points at once permits of the maximum cooling effect of the air and reduces the danger of bursting on account of freezing.
It will be apparent that the zigzag water passages 30 and air ducts 26, 29 of the complete radiator are both formed simply by securing together side by side a plurality of cellular unit-s shown in Fig. 4, which in turn are each made by securing in closed loop form, a single stamping shown in Fig. 2. Both the water and the air are in full and equal contact with the corrugated portions 11, with only one thickness of sheet metal separating them, while the folded portions 14 and intermediate portions 13 form additional means of extraction and radia tion of the heat from the water in the passages. The zig-zag water passageways 30, being rightangular, cause the water in its movement to strike-the common walls of the water passages and air ducts with considerable impact. This brings the stream by reason of the sharp angular turns into intimate contact with the Walls and retards the flow of water without clogging, causing the eflicient transmission of its heat to the cooling air passing through the adjacent air passages 29.
- In the cellular formation of the radiator produced by the units 25,- the folded portions 14, which form the horizontal-sides of the end cells 26 of the air ducts, are in horizontal alinement when the units are assembled, thus providing with the alined double vertical walls 13, a' very strong structure of pleasing ap earance.
