Description
Patented Jan. 27, 1931 UNITED srarelas ,PATENT orrica SAM BRISKIN,
F CHICAGO, ILLINOIS, ASSIGNOR TOEXCEL AUTO RADIATOR COMPANY,
OF CHICAGO, ILLINOIS, A CORPORATION OF DELAWARE RADIATOR Application filed October 3, 1928. Serial No.-,S`10,0.72.
The present invention relates to radiators, such as those used inrmotor vehicles, and has reference more particularly to thestructure of `the radiator core.
Among the objects of the invention is to provide a novel radiator core with increased heat exchange characteristics and increased exposed surfaces for both the water and air contacts when the water is the mediumto be m cooled or changed in temperature and the air isthe cooling medium, such as in an automobile radiator.
Another object is to provide such a core with increased length of travel of the water 7 as also a more devious path whereby greater cooling can be effectedin a given period of time and also whereby the passage of the water is subjected to cooling effects for a greater length of time.
2o the air passages as to cause a greater spread of the air streams over anl increased absorbing or heat transferring surface, by causing the air to be deflected, parted or `otherwise made to take deviated Vor tortuous paths whereby the air more efliciently coo-ls the walls ofthe water channels. This maybe effected by a suitably formed or shaped spacer or interspacer between a pair of water channels, such that the contact between the spacer and the neighboring walls of the channels,
shall be only in a few points or lines, thus eliminating contacts over extended surface areas as heretofore, and providing for a sub- ,36 stantially total or complete exposure of the surfaces of the channel Walls to the cooling fluid, such as the air.
points, it is to be understood that the struc- 4o ture is such lthat Ythe interspacer may not be in contact with the side walls of the waterv A further object is to so passthe air into Although mention is made of contacting of these` parts 'in a few channel walls are secured'or soldered to the i marginal portions'of the-interspac'er.
Other objects, advantages, capabilities' andl features are comprehended'by the invention as will later appear .and as are inherently possessed thereb Referring to t e drawings p Fig; l is a View in elevation ofa-part of a core constructed lin accordance with vthe *invention; y i

cer
to provide a passage or channel' forlthe liq uid tobe cooled, such as water. `vBetween the wall 1 of one channel and the wall'2 of anotherchannel is a space lthrough-which air orother cooling medium passesltransversely for absorbing heat from-the neighboring surfaces of 'the wal'lsx and 3,and1in this-space islocated aspacer or interspacer, allas lclearly shown in Fig. 3 ofthe drawings. r
The sidewalls l and 2zofafpair .of water channels areymadefof strips Aof .thin metal and are connected at the upper and lower ends by -a lock seam .c6 or the like, which may be suitably made fluid tight, as by :sol dering.V The spacer 5 kis lalso preferably made of thin metal and merely is inserted inthe .space 4 withthe ends of the spacer in contact With the top .and bottom walls `7 of Athesection or segment of the core.
Each water channel wall is formed with bent portions or corrugations so as to provide indentations or dihedral angles 8, which may be more or less acute and with intermediate or dj oining bent portions forming obtuse angle portions 9. By malring each of the metal strips with these indenta-tions, it will become apparent that the surface along the same will be greatly in creased in area so that the water passing over such surface will have a longer path of travel as also having a deviated or tortuous path, thus tending to decrease the speed of flow of the water as well as increasing the length of time of passage of the water through the channel.
The interspacer 5 extends normally substantially through a medial plane in the space e, and has medial body'portions 10` and laterally indented er bent portions 11 and 12 extending in opposite directions from the medial plane in which the inter-spacer is located. These indent-ations 11 and 12 are located opposite the indentations 8 of the water channel walls and may contact with the same at a few points, or along a line of Contact. in this way the sides of the indentations 8 are wholly out of contact with the sides or any other portion of the interspacer, thus giving increased exposed surface for cooling effect when the air passes between the interspacer and the channel side walls.
The marginal or edge portion of the channel walls and the interspacers are formed and shaped to be brought together into polygonal form, such as hexagons, shown in Fig. 1 of the drawings. The hexagone form openings at the ends of the passages l in which the interspacer is located. Referring to Fig. 1, it will be noted that the indentations in the interspacer and also in the channelfwalls vare located substantially along the axes'of the hexagonal openings, so that as air enters into these openings, it will first be deflected by the tapered surfacesl 14 and is then caused to iow into two streams over the tapered portion 13 and on both sides ofthe indentations 11 or 12. Also it will be noted that the adjacent indentation 8 is also located to receive the air which passes over the inclined surface 15 and is then parted to pass on both sides of the angle or indentation 8.
For the 'purpose of aiding the positioning of the different elements whenvassembling and ready for soldering the marginal portions, the sides of the hexagons may be pro,
vided with suitable projections 16 adapted' to fit in suitable depressions 17 formed in the adjac '.1 contacting s rface of the hexagons. it ien so assembled, the marginal portions may then be dipped in molten solder and after cooling, these marginal portions areseale-d together against leakage of fluid.
1n operation, the waterpasses downwardly through the channels 3 and the air passes transversely through the hexagonal openings and into the passages l, where the air streams are caused to spread over the entire surface of the channel walls as well as over the entire surfaces on both sides of the interspacer. 1t will be noted that the space between one of the dihedral angles 9 and adjacent portions of the angles 8, and the opposite portions of the interspacer, is substantially narrow, so that there is a greater chance of all of the air coming in contact with the outer channell surface or wall for increased cooling effect.
Vhile I have hereindescribed and upon i the drawings shown an illustrati veembodi ment of the invention and its mode of use, it is to be understood that lthe invention comprehends other constructions, details, arrangements of parts, and features without departing from the spirit thereof.
Having thus disclosed the invention, I claim:
1. A radiator core comprising two walls connected at their ends and having relatively spaced apart areas provided with inwardly extended apexed ribs of angular cross section, and an imperforate sheet-like spacer interposed between said walls and having oppositely extended apexed ribs of similar angular cross section, the high portions of the spacer ribs engaging with the high portions ofthe wall ribs with a contact of minimum area, so that approximately the entire surfaces of the walls onV both sides of the spacer ar-e exposed to the air streams passing through the core, the marginal portions of said walls and said spacer having air inlet openings, the contacting portions of said ribs being located along the axes of said openings.
2. A radiator core comprising two walls connected at their ends and having relatively spaced apart areas provided with inwardly extended apexed ribs of angular cross section, an imperforate sheet-like spacer positioned to extend approximately through the medial plane in the space between said separated areas, the body of said spacer having oppositely extended-laterally indented ribs of approximately angular cross section, the high portions of the spacer ribs engaging with the high portions of the Wall ribs so that substantially the entire surfaces of the Walls on both sides of the spacer are exposed to Contact with the air streams passing through the radiator, said Walls and said spacer having marginal` portions forming air inlet openings, the contacting portions of said ribs being located along the axes oi said openings, said `spacer having deleetor portions adjacent said openings.
In Witness whereof, I hereunto subscribe my name to this speoication.
