CARL S. CARLBERG, OF IVIOUND, MINNESOTA, ASSIGNOR, BY DIRECT AND MESNE AS- SIGNMENTS, TO PRESSTEEL RADIATOR CGli-IPAHY, A CORPORATION OF MINNESOTA.
RADIATOR.
Application filed August 31, 1925.
This invention relates to radiators and especially to that class of radiators adapted to be connected to a hot water or steam circulating system for heating the interior of houses or other buildings.
The invention has for its main object to provide a radiator of this class extremely simple in structure, light in weight, and capable of being manufactured at little cost,
which will have a comparatively large amount of radiating surface although requiring only a small volume of heating fluid. The inventor has in mind to decrease the volume of the heating fluid used in standard radiators today, without decreasing to any considerable extent the radiating surface.
A further object of the invention is to provide means for causing the upward circulation in the radiating units to be at the outer sides or radiating surfaces of the ra diator and the downward circulation therein to be at the central portion thereof.
It is a. further object to provide a radiator having smooth unobstructed surfaces, both on the inner side for the heating fluid, and on the outer side of the radiator for the air, whereby a high degree of efficiency may be obtained. This structure also permits the outside of the casing to be readily cleaned or dusted.
It is a more specific object of the invention to provide a radiator for buildings comprising a casing constructed of bent or pressed sheet metal with vertically corrugated sides, the corrugations forming a plurality of relatively thin heat units or cells having relatively wide radiating surfaces connected throughout their height by a. plurality of passageways, the space between any two of said cells being considerably greater than the thickness of a single cell.
It is also an object of the invention to provide top and bottom caps for the radiator conforming in shape to the periphery of the vertical walls, having outwardly projecting flanges to permit said caps to be inset at the top and bottom of the walls, whereby the edges will coincide with the edges of the walls to permit said edges to be readily welded together without injury to the walls of the radiator.
These and other objects of the invention Serial No. 53,462.
will be apparent from the following description made in connection wlth the accompanying drawin s, wherein like reference Fig. 1 is a somewhat diagrammatical view,
mostly in side elevation and partly in section, of the preferred form of the inven tion;
Fig. 2 is a plan view of the same, some parts being broken away, and some parts shown in section;
Fig. 3 is an end elevation of the device;
Fig. 4 is a cross section taken on the line d lof Fig. 2;
Fig. 5 is a cross section on an enlarged scale showing the structure of the top cap, taken on the line 5-5 of Fig. 2;
Fig. 6 is a fragmentary cross section on an enlarged scale taken on the line 66 of Fig. 2, showing the means for mounting the bafiie plate in the radiator; and
Fig. 7 is a horizontal cross section on an enlarged scale taken on the line 77 of F 1.
In the preferred form of the invention illustrated, a substantially rectangular shaped casing A is shown, constructed of sheet metal. The vertical walls of this casing are preferably bent or pressed from two pieces of sheet metal seamed together at the diagonally opposite corners of the radiator, having the longitudinal sides provided with a plurality of relatively narrow vertically extending corrugations 8, and the flat end walls 8 The corrugations 8 project outwardly for some distance and are spaced apart at .a distance considerably greater than the thickness of one corrugation, best shown in Fig. 7.
To close the top and bottom of the radiator casing, top and bottom cap members 9 are provided, identical in all respects, formed similar in shape to the perimeters of the vertical walls, and having outwardly projecting flanges 9 at right angles thereto, said flanges being adapted to lie flush against the upper and lower ends, respectively, of the vertical walls with the cap portions inset from the edges thereof, thereby leaving the edges of the flanges flush with the edges at the top and bottom portions of lUU the vertical walls. The projecting these members are easily welded t without any danger of damaging the walls the radiator. jrn 'ntake passageway con'nnunicates with one of the cnds of the casing A at preferably lower central portion ther of while an outlet pass ,geway l0 con'nnunio at the opposite end of the casing, said 1 agcwais being preferably horizontally alnied.
lhe oppositely alined corrugations 8 on the two longitudinal sides of the radiator, as shown in Figs. 2 and 7, divide the casing into a plurality of radiating units or cells 7), interconnected by i'neans of plurality of relatively narrow centrally disposed pas- :agev ,ays c The passageways 0, of course, extend the full height of the casing and of the cells D. The radiation surfaces of corrugations 8 are comparatively wide with respect to the depth or thickness thereof and are disposed in parallel arrangoment. Tihe casing 1%., therefore, has a large radiating area with a plurality of air passages (Z formed between the corrugations 8 and extending vertically from the bottom of the casing to the top. Air passages (Z areconsiderably wider than the thickness of the cells 6 as best shown in Fig. 7. A horizontally extending baffle plate l? is supported within casing A on a line just above the intake and outlet openings 10 and 10, respectively. I
Baffle plate P is preferably constructed of flat sheet metal, extending centrally and longitudinally of casing A and falling short a trifle of traversing the entire casing, thercby leaving the end cells Z) of the casing unobstructed. The passageways 0 are completely restricted by the baffle plate, while a substantial'portion of the cells I) are traversed, the plate l? being slightly wider at the portions through said cells. The sides of the cells formed by corrugations 8, are left unrestricted. To secure plate P in the casing a plurality of horizontally alined lugs 8" are struck up from the sides of the casing, between which the plate is mounted in the assembling of easing A.
A pair of vertically disposed flat end members 11 embrace the ends of the casing A, having at their lower portions the legs 11 adapted to rest on the floor or other supporting surface, and members 11 are clamped together at their lower portions by means of apair of horizontally alined tie rodsIQ, upon whichthe casing A is supported. A third tie rod 13 extends through the central portion of the casing A, piercing the outer surfaces of the end cells and passing through the end members 11 and through the top portions of the passages 0 and cells 0. The tie rods 12 and 13 securely clamp the casing it within the frame, likewise reenforcing the radiator and preventing expansion of the incense sheet metal from which the casing is constructed ltecesses 11 are provided in the central lower portions of the frame members 11 to accommodate the projecting portions of the intake passageways 10.
A cover 14- isprovided for easing A, formed similar in shape to the top or cap 9 thereof, having the rounded flanged sides projecting slightly beyond the top of the casing A and having the relatively thin end portions 14 adapted to be seated in horizontal grooves provided in the inner sides of the upper portions of frame member 11. Cover ft l, being constructed of sheet metal, may be readily removed or secured by springing the end portions slightly.
in operation the radiator bein connected e in a hot water or steam circulating system,
the heating fluid will enter the intake pass z 'e 10, a substantial portion of the enterlng ll passing beneath the baffle plate P. Substantial amounts of this fluid will be deflected by plate P to the sides of radlatlng portions of the cells 7), thereby setting up an upward circulation with the hot heating fluid at the outer sides or corrugations of the radiator. The return or drop in circulation will naturally occur at the central portions of the cells and in the passageways 0, thus the hottest portion of the circulation in the radiator will take place at the sides of the cells having the relatively wide parallel radiating surfaces. The vertical air passages (Z extend from the bottom of the casing A through the top, thereby permitting a considerable draftof air to pass over the radiating surfaces, and, as has been stated, these air passages are considerably wider than the thickness of a single cell 6.
The radiator is obviously reversible, that is, either end may be connected as the intake end. 7
Since thecells Z) are-relatively thin but have wide parallel radiating surfaces, it will be noticed that a large amount of radiation may be obtained from an extremely small volume of circulating fluid and that the radiating surfaces of the several cells and passages will be subjected to the action of the air moving upwardly along the wide air passages (Z.
The construction of the frame and supporting and clamping rods provides a highly efficient means for supporting the casing and re-enforcing the same to prevent expansion when the pressure is high.
When the cover 14 is removed, the smooth corrugated portions may be quickly cleaned, having no rough surfaces to accumulate dirt or dust.
The portability and light weight of the device, of course, constitute important features of the invention.
From the above description, it will, be seen that applicant has invented an extremely ill) simple but highly etficient radiator of the class described, highly successful for all the purposes intended.
It will, of course, be understood that various changes may be made in the form, proportions, details and arrangements of the parts without departing from the scope of the invention.
lVhat is claimed is:
1. A. radiator of the class described comprising a plurality of vertically spaced fluid containing cells, a plurality of passages connect-ing said cells and a horizontally extending baffle plate extending transversely across said cells and passageways and hav ing a plurality of widened portions disposed across substantial portions of said cells.
2. A radiator of the class described having two of its opposite sides provided with a plurality of vertically extending symmetrically arranged corrugations, an intake to said'radiator and a horizontally extending battle plate disposed above said intake and adapted to deflect the circulating fluid in its upward movement towards said corrugations, said baifle plate traversing said passageways and having fingers traversing sub stantial portions of the interior of said corrugations.
3. A radiator of the class described com prising a plurality of spaced fluid containing cells, a plurality of passages connecting said cells, and a transversely disposed baffle plate extending across said cells and passageways leaving openings at the sides of said cells for the passage of circulating fluid.
In testimony whereof I aflix my signature.
