RADIATOR.

Application filed July 14, 1920. Serial No. 396,254.

To all whom it may concern:

Be it known that I, SWEN R. SwENsoN, a citizen of the United States, and a resident of New Haven, in the county ofNew Haven and State of Connecticut, have invented certain new and useful Improvements in Radiators, of whichthe following is a specification.

This invention relates to radiators and is more especially directed toa radiator of the type adapted for use in combination with an internal-combustion engine. r

The object of the invention is the provision of a core forradiators of this character 5 which is simple in construction, cheapv to manufacture, and of high heat-radiating capacity.

To accomplish the object of this invention and to improvegenerally upon devices of this character, the core is composed of a plurality ofparallel plates of thin sheet metal, each of which plates is stamped to provide successive series of preferably cup-like or frusto-conical projections extending in opposite directions from the plate, certain of which projections serve to space apart the adjacent plates. The side edgesof successive pairs of plates are joined together to form a water passage. The projections extending from each plate of a pair toward the remaining plate to space apart said plates preferably contact with the surface of the coacting plate and are of'relatively slight depth. The remaining projections of each plate are of somewhat greater depth.

and a portion thereof contact with and are soldered or otherwise connected to similar projections of the adjacent plate of the contiguous pair. Such of these latter projec tions as do not contact with similar projections extend approximately half way across the air passages. The projections extending into the air passages form pockets connecting with the water-passages and a1'e.ar ranged in a stag ered relation. By having only so many of the water pocket projections of each plate in contact with like projections of the adjacent plate of the contiguous air as are necessary to give to the pressure of the water, and having the re maining water pocket projections offset from each other or staggered; the air in traversing the air passages is reflected from one plate to the other and is also deflected alternately upwardly and downwardly and is therefore swirled around in sucha manner that all of it comes in contact with-the metal of the plates. j,

In the accompanying drawings is disclosed a specific embodiment of my inven tion wherein 1 Fig. 1 is a front elevation of a embodying the invention;

Fig. 2 is aside elevation of one face of a water tube; 1 1

radiator of a tube;

Fig. 4: is an enlarged fragmentary front elevationof a core; I

Fig. 5 is a section on line 5-5 of Fig. 2.

Interposed between the upper and lower water tanks 1 and 2, respectively, of a radiator is the core or cooling unit 3. This unit is composed of a succession of parallel plates 1 having offset side edges, the offset edges of each pair of plates being arranged to. contact with each other to space apart the plates of the pair and which offset edges are soldered or otherwise permanently. joined together, whereby are formed the water passages. .Vertical rows of relatively small projections 4; are stamped fromone or both plates of a pair in the same direction that the edges are offset, and said projections are so arranged that they extend fromonevplate of the aforementioned pairs to the other and cooperate with the offset edges to space apart the plates of a pair to form water passages. These projections may extend alternately from each plate ofa pair or theyinay all extend flOHL a single plate. Arranged vertically of the plates and near the edges thereof are rows of relatively large stamped projections 5 which are extended from the plate in a direction opposite to that of the projections 4.-. Each of the projections5 of a plate contact with aisimilar projection of. the adjacent plate of the contiguous pair and said contacting projections are joined to- Fig. 3 is a side elevation of the other face i plates are assembled to form a radiator core,-j

each projection 6 is offset from each projection 6 of the other plate-of the pair.

For convenience of manufacture the plates may advantageously begroupednintosections before the core is assembled, eachsection being coinposed'ofza pair ofplate's; For instance, a sheet of metal. of a-width equal to twice the depth of the finished coremay' have its side: edges anda narrow strip alongits center lrne offset 111 the same directionand stamped to provide -on either side of its central strip the proper projections, after which the sheet is folded along the center line to bring into-' oontactfthe''side edges thereof, which are then joined together, or, two properly-stamped strips with offset edges may be positioned niththesoi'lset edges in contact and the sideedgesjoined together. Instead of proceeding in this manner,"a strip a trifle longer than the height of the core properly stamped and with its dges olis'et nia-y be-fold'ed "about a trans- "verseline, the side edgesjoined together,

and the closed endofthesection openedto Pl'OVlClG- a passage through the-section. The grouping oi the plates according toany of these methods forms awater passage section.

Other methods of assembly, such the groupingof the plates to form air-passage sections, will suggest themselves to one skilled in the art- 0f makingradiators. faces of the projections are tinned after the plateshave been formed into sections,

after which such sections are grouped together with-the projections o of each plate in contact with the adjacent plate of "the contiguous water, passage 'sectioinzand the "tinned projections sweat-ed together.-

It is, of course, Understood that the particular device shown and described in the present application illustrates merely a preferred form of construction and an arrangementof pa rts',-'which., it has been found,-w.ill successfully carry out the principles of my inventioin and that various changes and modifications of details may easily be made without departin from Ktlre' spirit of my invention as defined 1n the ape pended claims;
