RADIATOR UNIT.

Specification of Letters Patent.

Patented Not/22,1921.

To all whom it may concern.

Be it known that I, JOHN M. Fnonnns, a citizen of the United States, residing at 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 unit which is so constructed that a plurality of such units when assembled produce a core for radiators.

The object ofthis invention is to produce a unit of this character which when assembled with others to form a core will not slide laterally out of place, and also provide a staggered water passage between adjacent units which increases the radiating efficiency, said units being also provided with integral wings which project into the air passages and promote the radiation of heat from the water passing-through the water passages.

.. In the accompanying drawings:

Figure 1 is a fragmentary elevation, partly in section, of a radiator containing my improved units. Fig. 2 is a horizontal section taken on line 2-2, Fig. 1. Fig. 3 is a vertical section taken on line 3-8, Fig. 1. Fig. 4 is a perspective view of one of the units.

Similar characters of reference indicate corresponding parts throughout the several views. Y c

In its'completed form the radiator comprises a plurality of tortuous water passages 10, preferably arranged vertically and a plurality of horizontal air tubes 11, 12 and '13 arranged between the water passages and extending fromthe front side to the rear s1de thereof, said passages communicating at opposite endswith water boxes or headers of which oneis shown for example, at 14 in Fig. 1, while theair tubes open at their opposite end to the atmosphere, so that the passage of the air through the air tubes carries away the heat of the water in the water passagesor channels. ,The core or heat exchanging section of the; radiator comprises a plurality of units each of which is con structed of a single strip of metal so as to form two parallel. air tubesll and 12 and a web 15 arranged between these tubes and formed integrally therewith, as shown in Fig. 4. The air tubes, as shown in Fig. 1, are hexagonal and the same are so arranged .to form triple corrugations on one side of the unit, double corrugations on the opposite side of the unit and two pairs of transverse walls. The triple, corrugation of'each unit comprises the intermediate member consisting of the web 15 which forms two facets 16 tapering outwardly tofa central longltudinalsummit 17 inthe form of a wedge, and I two side members each consisting of two facets 18. 19 tapering outwardly to a central longitudinalsummit 20 in the form of a wedge. Each of the pair of corrugations on the opposite side of the unit is arranged diametrically opposite one of the side members ofthe triple corrugations and forms two facets 21, 22, tapering outwardly to a central longitudinal-summit 23 in the form of a wedge. Each pair of transverse walls consists of an outer transverse member 25 forming a facet which connects the outer longitudinal edges of one of the outer facets 19 of the triple corrugations and one of the outer facets 22 of the-double corrugations, and an inner transverse member 241- forming a facet which is connected at one of its longitudinal edges with the inner longitudinal edge of the inner facet 21 of one of said pair of corrugations while its other longitudinal edge engages'with the base between the inner facet 18 of one of theside members of the triple corrugations and the adjacent facet 16 of the intermediate member of the triple corrugations.- The opposite ends of the outer facets 19 of the side members of the. triple corrugations and of the outer facets 22 of the members of'the double corrugations and of the outer wall members 25 are provided with lateral off-sets 26. j

In the assembled: condition of'a plurality of such units the outer facet 19 of one side member of the triple corrugations is opposite an inner facet 21 of one member of the pair of corrugationsand the facets 16 on unit-S :howievflr .3 ngage each other along 11.

the intermediate members of the triple corlrugations of adjacent units together also form addit1onal air tubes 13. The several units engage each other with a wedgingaction owing to thetapering formation of the cooperating surfaces, thereby operating to center the units relatively to each other and preventing the units from sliding laterally out of place while being assembled-and permitting the fr'ontand rear ends of the units 7 to he-easilysoldered, so as to seal the water passages and connect the several units with each other, 7

Furthermore, by formingthe hexagonal tubes so that each air tube has a wedge formation on its diametrically opposite sides and on aline, parallel with the general direction of the water passages a minimum contact o f rnetal between adjacent units is }obtained,,the engagement of each unit in this instancewith an ad acent unit occurring at not more than three places, thereby" obtaining the maximum radiating efficiency for the amount of 'metal' employed.

order to, further increase the radiating efficiency of the unit each of theinner Walls of a-pair is provided with a plurality of rad atlng wings or fins 27 which are punched or cut out rot-these walls so .as to remainintegrally. connected therewith and project laterally into the air path, thereby causingfthe air to be interceptedand cause the same tocarry away theheat from the water in the channels more efiiciently.
