Application filed March 3,
T 0 all whom it may concern:
Be it known that l, dorm M. Fnonnns, a citizen of the United residin in Buffalo. in the county of Erie and State of New York, have invented new and useful improvements in Radiator Units, of which the following is a specification.
This invention relates to a radiator which is more particularly designed for cooling the water or explosion engines and it has for its object the production of a radiator of this character waereby the l .iaximuin radiating elhciency is obtained. with a minimum use of metal while preserving the artistic appearance of honeycomb radiators now in common use.
In the accompanying drawings:
Figure 1 is a fragmentary sectional front elevation of radiator embodying my invention. Fig. 2 is a section of the same taken on line il-2, Fig. 1. Fig. is a perspective view of one of the units which enter into the composition of the radiator.
Similar characters of reference refer to like parts throughout the several views.
In its general organization the radiator comprises a plurality of upright water passages 10 and a plurality of horizontal a r tubes 11., 12, 13, said passages communicating at their corresponding ends with a water be or header of which one is shown, for example, at let in Fig. 1, while the air tubes open at their opposite ends to the external atmosphere to pe-. it the passage of a r through the same for cooling the water in the water tubes. The core or heat exchang ing section of the radiator comprises plurality of units each of which is constructed from a single strip of sheet metal so as to form two integral air tubes 11 and 12 and a straight web 15 arranged between the tubes 11, 12 and formed integrally therewith. The air tubes of the units shown in Figs. 1 and 3 are hexagonal in cross section and the Web15 connects the opposing salients midway between opposite sides of the companion air tubes. In assembling a plurality of such units the top and bottom facets of the several air tubes 11 engage with each other and form one row or tier of integral air tubes, the top and bottom facets of the several air tubes 12 engage each other and form another row or tier of integral air tubes, and the webs 15 of the several units in coop- Specification of Letters Patent. Patented Dag. 20 1921.
13, each of these integral and non-integral J air tubes being of hexagonal form in cross section. The top and bottom facets 16 of the integral air tubes of each unit are straight and flat throughout the length of same, so that when these facets engage corresponding facets of adjacent units they may be reliably soldered together or otherwise connected to produce a water tight joint therebetween. The inner facets 17 of the integral airvtubes and the webs 15 are also for convenience and economy made pertectly flat and straight throughout the length of the same but they may be otherwise formed if desired. The outer facets 18 of the integral air tubes are provided at their opposite ends with lateral oil-sets 19 so that when these ofi-sets on the outer sides of one group of units engage corresponding elf-sets on the outer sides of the integral air tubes of adjacent groups of units water passages 11 will be formed between the same which are or serpentine or zig-zag form.
The cooperating surfaces of the off-sets of adjacent groups of units are united by solder to prevent leakage of water therefrom.
in this manner a cellular radiator core is produced inwhich a' plurality of rows of air tubes are formed between every pair of water passages in a manner which requires a minimum of metal but insures a high radiating etliciency and preserves the desirable cellular appearance of the core.
The radiating efiiciency of the units is further increased by providing those parts thereol which do not form walls of the water conduits with radiating fins which are preferably formed integrally with these units from the same strip of metal. This may be accomplished by forming these fins in the shape of a plurality of flat wings 20 which are struck out of the facets 1? of the units or by pushing the metal of the web into the form of a plurality of tubular projections or bosses 21. The wings 20 on each "facet 17 are preferably arranged in a longitudinal row and bent inwardly into the air path within the respective tube, the angle of the several fins or wings relative to the axis of the re-. spective tube being dilierent, so that these fins are spread out like a fan when viewed from the end of an air tube, as shown in Fig. l, and thus effectively intercept the air and compel the same to carry .011 the heat from the water.
The boss shaped fins 21 are preferably pushed or struck up out of the webs in a lon-- gitudinal row so that they extend into the path of the, air passing throughthe tubes 13 and thus increase the dissipation of heat from the water to the atmosphere.
I claim as my invention:
#1. A radiator unit comprising a plurality of parallel tubes which are constructed from a single strip of metal and have their adj cent sides connected wit-h each other, and
"which are". provided with radiating fins struckintegrally out of said metal strip.
2. A radiator unit comprising a plurality of parallel tubes whichare constructed from a single strip of metal and have their adj a-' cent sides connected with each other, and the inner. adjacent sides of said tubes being straight while the outer sides of the same are off-set at opposite ends thereof, and said inraces i ner sides being provided with radiating fins struck integrally out of said metal strip.
3. A radiator unit comprising a! pair of tubes arranged parallel and a' web "connecting the adjacent sides of saidtubes, said tubes and web being constructed integrally from a single strip of sheet metal, the adjacent inner sides of said tube being straight while the outer sides thereof'are oil-set at 0pposite ends thereof, the inner facets cfsaid tubes being provided with a plurality of wing shaped radiating fins, and said webs being provided with a plurality of fins having the form of tubular bosses or projections.
