BIBBED BODY FOR HEAT-INTERGHANGE DEVICES.
Specification of Letters Patent.
Patented May 11, 1920.
Application filed September 23, 1918. Serial No. 255,309.
Be it known that l, HANS GUYER, a citizen of the Republic of Switzerland. residing at Zurich, Switzerland, have invented certain new and useful Improvements in Ribbed Bodies for Hleat-lnterchange Devices; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification. a
This invention relates to improvements in compound ribbed bodies for heat interchange devices. The invention consists in pressing Ll-shaped ribs ot sheet-metal with the transverse side of their I'd-shape by means of shrunk rings against the main body and in soldering said ribs to the main body by means of a metallic coating produced in a metallic bath. When the ribbed body has a cylindrical shape and is pro-- vided with ribs parallel to its axis, several groups of ii -shaped ribs of sheet-metal can be distributed over the length of said main body.
The invention will now be more partic e" larly described with reference to the ac companying drawing illustrating by way oi? example two embodiments of the invention. In this drawing:
Figure l is a vertical longitudinal section through a vessel-shaped ribbed. body provided with a group oi ribs.
Fig. 2 is a. corresponding horizontal section on line of 1.
3 to 6 illustrate the manner in which the ribs are manufactured and Fig. 7 is a vertical longitudinal section through a tube provided with three groups of ribs of sheetmetal.
Fig. 8 is a view of a portion of an outer ring showing the notches for. spacing the Ll-shaped ribs, and
Fig. 9 is a similar view of an inner ring.
Referring to Fig. 1, 1 denotes a pressed pot or pan of wrought iron having a cover 2 and U-shapcd ribs 3. The latter are stamped out of a piece of sheet-metal and have first the shape shown in Fig. 8. They are already provided with recesses at to it which are for receiving the shrunk rings. The sheet-metal of flat form shown in Fig. 3 is then bent outward about the lines a-'b and cd at nearly right angles at the base, a finished rib having a U-shaped crosssection being thus obtained. Fig. 4 is a front view, Fig. 5 a side View and Fig. 6 a plan View of such a rib. Figs. 1 and 2 show how twelve such ribs may be arranged at an equal distancev from one another around about the vessel 1. They are pressed by means of inner shrunk rings 12 and 13 at the bases of the ribs and outer shrunk rings 14 and 15 at their outer edges against the main body. The shrunk rings shown in lfigs. 8 and 9 have on their edge corresponding notches, so that they are adapted to hr; and space the U-shaped ribs accurately in their proper position. The compound body hereinberore described is then dipped into a bath'of zinc. The liquid Zinc coats the whole outer surface of the compound body acting as a rust preventing layer. The liquid zinc penetrates moreover from both sides of each rib and also through the holes ,16 (Fig. 3) punched into the ribs of sheet-metal into the spaces existing between'the transverse side of the Ushaped ribs and the main body, soldering thereby the ribs to the main body. The connection thus obtained provides for a, good transmission of heat.
The ribs can be manufactured as a wholesale article. When a comparatively long tube has to be provided with ribs, several groups oi U-shaped ribs of sheet-metal. are distributed over the length of said tube. (A group consists of all the ribs arranged on the same height around about the tube.) Fig. 7 shows a. vertical cross-section through a tube provided "with three groups of ribs.

6. A ribbed body for heat interchange devices, comprising a cylindrical main body, U-shaped ribs' of sheet-metal arranged parallel to the axis of said body, inner shrunk rings engaging the transverse sides of the ribs and pressing them against the main body, outer shrunk rings engaging the free ends of the sides of said ribs and spacing the latter at a regular pitch and stiffening them, and a metallic coating for the whole soldering theribs to said shrunk rings and to the main body.
7. A heat interchange device comprising a body portion, radial sheet metal ribs for said body portion having notches at their bases and on their outer edges and rings engaging said notches and shrinking the ribs to said body portion.
8. A heat interchange device comprising a body portion, radial sheet metal ribs for said body portion having notches at their bases and at their outer corners, and rings in shrunk engagement with said notches.
