Definitions

  • This invention has for its object a rolled .metal radiator in which the mechanical resistance and the conductivity of the metal are utilized to the best advantage.
  • the two inner plates arethick and comprise corrugations which form vertical and horizontal passages there- 'between for the circulation of the heating fluid;
  • the outer plates are thin and comprise I flutes which together with the corrugations in the thick plates form vertical passages-open at the bottom and the top thereof and the walls of which are swept over by the air which rises therein as aresult of its increase in temperature;
  • Figure 1 is an elevational view, parts being broken away.
  • Figures 2 and 3 are horizontal cross sectional views taken on lines 22 and 33 of Fig. 1 respectively.
  • Figures 4 and 5 are vertical cross sectional views taken on lines H and 55 of Fig. 1 respectively.
  • the radiator as shown comprises two inner juxtaposed corrugated metal sheets 1 the corrugations 2 of which provide vertical tubes 3 therebetween; these corrugations end at some distance short of the upper and lower extremities of the sheets and the upper and lower edges of the said sheets are flanged inwardly so as to provide between the said flanges and the ends of the corrugations an upper supply manifold 3a and a lower disj charge manifold 35 preferably, the sectional area of these manifolds is of narrow width oneplane with the said the sheets 5 and the air channels 7 practically cent edges of the outer metal sheets;'the latter and'3b respectively provide for the supply and discharge of the heating fluid.
  • manifolds have exactly the same width asthe vertical conduits 3, their lateral faces being each inone plane with the outer generatrixes of the corrugations providing such conduits.
  • the radiator in addition comprises two 5 outer likewise corrugated metal sheets 5 the flutes 6 of which are equal in width to the corrugations 2 of the inner metal sheets 1 and provide therewith vertical channels 7 Y open at the bottom and top thereof.
  • the inner generatrixes of the corrugations in the sheets 5 are laid upon the outer generatrixes of the corrugations providing the conduits 3 and extend also on those lateral faces of the manifolds 3a and 3b which are located in generatrixes, so that extend over the whole height of the radiator.
  • the outer sheets 5 are assembled by welding or riveting with the inner metal-sheets 1 so so as to provide a good heat conductiveness between the same along the adjacent genera trixes of the corrugations and along the adj asheets.
  • the inner metal sheets 1 are thick so that they can withstand the inner pressure and corrosion of the fluid; on the contrary the outer metal sheets are of thin construction as they are'not to resist any pressure and aresimply swept over by the surrounding air.
  • the hot fluid comes in at the top and out at the bottom.
  • the heat is transmitted through the inner metal sheets to the thin show a considerable linear development; they are swept over by the air flowing upwardly at either side thereof and thereby provide'for a heat dissemination which is as efiic'ient as possible.
  • Some advantages amongst those of the radiator according to the invention are its very 1GB internal pressures and low cost, its easy manufacture along repetition work lines, its considerable lightness, its perfect stiffness, its eflioiency on account of the high ascensional speed of the air within the conduits 7.
  • the surface of heat transmission to the air comprises the outer surface of the sheets 1 and the inner and outer surfaces of the sheets 5; thus,it is a considerable one comparatively to the weight of the radiator, which itself is at least three times lighter than the lightest castiron'radiators.
  • the heat output or heating power is considerable withr-eference to both the dimensions and the weight of the apparatus.
  • the metal is distributed rationally and in themanner .most favourable for lightness,
  • sheet metal is not brittle as cast iron is, and that it can be repaired easily by welding while a burst out or broken cast iron radiator has to be scrapped.
  • the overall thickness 6 of the radiator is very small, e. g. 3", so that it can be accommodated in a shallow recess in a wall or even a partition. Securing may be obtained by means of straps with unimportant sealing work, even. on a thin wall.
  • This radiator is also advantageous from the sanitary point of view as ithas no horizontal surfaces which will retain dust, and also because the greater portion oft-he surface of heat-transmission tothe air, particularly thoseof sheets 5, is at a temperature which is lower than that of the hot fluid, so that the heating is very mild. and a very limited amount of heat is radiated directly.
  • the radiator generallyprovides V-a continuous,i. e. imperfor-ate panel, and can completely close an opening in a partition betweentwo rooms, so asto heat-both rooms at the same time without setting them into communication with each other.
  • a sheet metal radiator comprising a pair of metal sheets having vertical corrugations extending over part of their height .tions and having an upper fold connected together by vertical channels and having their upper and lower edgesbent inwardly, the said sheets having their flanges and the inner generatrixes of their corrugations juxtaposed so as to provide between the said upper and lower flanges and the respective ends of the said corrugations, horizontal manifolds into which the vertical conduits formed by the said corrugations open, and a pair of metal sheets provided with vertical corrugations and applied respectively with the .inner-generatrixes of their corrugations against the outer generatrixes of the corrugations of the first mentioned sheets, the said sheets providing therebetween air channels open at the top and'bottomthereof.
  • a sheet metal radiator comprising a pair of metal sheetshaving vertical corrugations extending over part o'f'their height andhaving their upper and lower edgesbent inwardly, the said sheets having their flanges and the inner generatrixes of their corrugation'juxt-aposed so as to provide between the said upper and lower flanges and the respective ends of the said corrugations, horizontal manifolds into which the vertical-conduits formed by'the said corrugations open,
