RADIATOR AND METHOD FOR MANUFACTURING THE SAME.
Specification of Letters Patent.
Patented Sept. 8, 191%.
Application filed July 20, 1910. Serial Nb. 572,799.
To all whom it may concern:
Be it known that I, ToRBJoRN LINGA, a subject of the King of Norway, residing at Thor, in the county of Humboldt, State of Iowa, have invented certain new and useful Improvements in Radiators and Methods for Manufacturing the Same, of which the following is a specification.
My invention relates to radiators and refers particularly to radiators which are formed from sheet metal.
The object of my invention is to produce a radiator which is of cheap construction and which exposes a large radiation area in order to obtain a high efficiency. To accomplish these results 1 first produce corrugations in one of the metal sheets by any of the well known methods, and then asten a second sheet to this corrugated sheet by suitably bending over and uniting the edges of these sheets. The object of the corrugations is to separate the two sheets from each other,
thus formin a casing suitable for the reception of the f iuid which is to be cooled in the radiator. Besides the corrugations just mentioned I also produce a longitudinal corrugation which divides the easing into two chambers, these chambers being connected toward the end of the casing through which the corrugation does not" extend. Suitable inlet and outlet openings are provided in the casing which is then rolled into a spiral or other suitable shape, both of these openings being preferably on the outside of the spiral thus formed. These and other advantages of my invention will be more apparent by reference to the accompanying drawings which represent a preferred embodiment of my improvements and in which:
Figure 1 is a front elevation of the com! pleted radiator partially broken away. Fig. 2 is a cross sectional view of the radiator shown taken on the line 22 in Fig.1 and showing the longitudinal corrugation in side elevation. Fig. 3 is a fragmentary elevation taken from the inside of the sheet having the inlet and outlet openings therein. Fig. 4 is a fragmentary elevation of the inside of the corrugated sheet. Fig. 5 is a transverse section on the line 55 of Fig. 4:. Fig. 6 is a transverse section on the line 6-6 of Fig. 3. Fig. 7 is a transverse section through both of the sheets shown in Figs. 5 and 6 illustrating the method of uniting the edges of the sheets.
In order to form the radiator 10, I first form the sheet 11 as indicated in Figs; 4: and 5, this operation'being performed by any of the well known methods. It will be noticed that the sheet 11 is provided with the short longitudinal corrugations l2 and a single longer corrugation 13. The edges of the sheet are bent to form the upstanding proections 14., the metal forming which, as will be noticed, is bent back on itself and extended to form the outer edge 14.
Figs. 3 and 6, couplings 16 and 17 being riveted or otherwise suitably attached to the sheet in order to provide inlet and outlet openings. The edges of the sheet are bent upwardly to form the flanges 18. When the two sheets have been formed, as just described, the sheet 11 is placed within the sheet 15 as indicated in Fig. 7, and the flanges 18 are then bent inwardly to form engagement with-the portions 14" of the sheet 11 and the projections 14 are then bent outwardly over the flanges 18. In order to make the joints perfectly fluid proof, solder may be applied to the same after the casing has been bent into spiral form. It will be noticed that the corrugations 12 engage the sheet 15, and the two sheets 11 and 15 are thus kept suitably spaced apart. The long corrugation 13 extends through most of the The companlon sheet 15 13 formed as indicated in length of the casing formed by the two sheets, and thus divides the same into two parallel chambers which communicate with the inlet opening formed by the coupling 16 and the outlet opening formed by the coupling 17. The next operation consists in bending the easing into the spiral shape best shown in Fig. 2. This pointed out that in practice the seaming-may be done a short distance in advance of the bending, whereby objectionable strains of bending which might cause buckling or sliding of parts is avoided.
In the operation of my improved radiator, fluid is introduced through the inlet opening formed by the coupling 16, and then passes through the lower chamber formed in the casing by the longitudinal corrugation 13, and then returns to the outlet opening formed by the per chamber of the casing. The path of said fluid is indicated by the arrows in Fig. 4.
It radiator embodying my invention possesses the important advantage that the laminated column or spiral sheet of air as cending through the radiator between the loo convolutions thereof is subjected in all its parts to a degree 0t heating which is substantially uniform in the aggregate as the outer convolutions are hottest at one end of the radiator and theinner convolutions are hottest at the other end, the heated fluid entering at the periphery at oneend and leaving at the periphery at the other end after traversing in its medial course the center of the spiral.
l am aware that spiral radiators have heretofore been manufactured, but the novelty of my present invention consists particularly in the use of corrugations in one of the sheets in order to keep the two sheets properly spaced apart, the use of a, partition which separates the easing into a pair oi parallel'chambers, and the special method of uniting the edges of the sheets. It will be apparent, however, to those skilled in the art that many changes could be made in the detailed construction of the parts which it have described Without departing from the spirit of my invention.
hat I claim is:
1. A spiral radiator comprising a pair of sheets united at their edges, one oi? said sheets having a longitudinal corrugation dividing the radiator into a pair-of chambers, one of said chambers being connected at one end With the inlet opening and the other at the same end'with ing of said radiator, and the two chambers connected with each other at the end removed from the inlet and outlet openings,
substantially as described.
2. A spiral radiator comprising a pair of sheets united at their edges, one of said sheets having a plurality of spacing corrugations, and a longitudinal corrugation dividing the radiator easing into a pair of chambers, the two chambers connected at sheets being the outlet open one end-with the inlet and outlet openings respectively and with eachother at the end removed from said openings, substantially as described.
3. A radiator comprising a pair of sheets united at their edges, one of said sheets having a longitudinal corrugation thereby dividing the radiator into a pair of chambers, said casing being in the form of a spiral, the two chambers connected at the outer end of the spiral with inlet and outlet openings respectively and with each other at the inner end of the spiral, substantially as described.
t. A radiator comprising a pair of spaced sheets united at their edges and having the interspace divided into two communicating chambers by a partition extending longitudinally from one end to a point sufiiciently removed from the other end to afi'ord a cross passage, an inlet to one of the chambers and an outlet from the other chamber at the end remote from the cross passage, the pair of bent into a spiral, substantially as described.
5. A radiator comprising a pair of sheets united at their edges and spaced apart by corrugations extending inwardly from one of the sheets, the interspace divided into two communicating chambers by a corrue gation extending lon itudinally from one end to a point sufiiciently removed from the other end to ad'ord a cross passage, an inlet to one of the chambers and an outlet from the other at the end remote from the cross passage, the pair of sheets being bent into a spiral with the inlet and outlet end exteriorly arranged.
