Patented Nov. 18, 1930 PATENT OFFICE PAUL M. LATTNER, F CEDAR RAPIDS, IOWA HEAT-CONDUCTING 'MEANS .FOR STEAM GENERATOBS 0R FLUID HEATEBB Application led October 31, 1928.
This invention relates to heat exchange structures and more particularly to structures wherein heat is transmitted from a. heating medium to a second medium to be heated by means of conductors cooperating with a Wall or the like whichA separates the said media.
An important object of the invention is to provide a structure suitable for confining and placing in heat exchange relation a medium to be heated and a heating medium and to combine with said structure means for materially increasing the number of heat units transmitted from one to the other of said 1I media and for lessening the time required to effect the transfer of said units.
A further important object of the invention is to provide a novel form of heat conducting member which is capable of use wherever it is desirable to transmit heat.
With the above and other objects in view which will more readily appear as the nature of the invention is better understood, the same consists in the novel construction, combination and arrangement of parts hereinafter more fully described, illustrated and claimed.
Preferred and practical embodiments of the invention are shown in the accompanying drawings in which:
Figure 1 is a partly vertical sectional and partly elevational view of a heat exchange structure embodying this invention.
Figure 2 is a fragmentary horizontal sectional view of a portion of a shell structure and illustrates a manner of attaching heat conducting means thereto.
Figures 3 and 3"L are detail perspective views of heat conducting members.
Figure 4 is a vertical sectional view of a modified form of heat exchange structure.
Figure 5 is a detail view illustrating the manner of attaching heat conducting members employed in the structure illustrated in Figure 4.
Figure 6 is a vertical sectional view of a further modified form of heat exchange structure.
I0 Figure 7 is a vertical sectional view of a Serial No. 316,234.
. scribed in connection with all of the figures as including a member (A) which confines a heating medium in the space (B). Located in heat exchange relation with the space (B) is a further means (C) adapted for confining a medium to be heated. Suitably carried by and secured tothe means (C) area plurality of heat conducting members (D) which project into the space (B) so as to absorb heat from the medium confined therein and conduct the said heat to the medium confined Within the means (C). It is to be understood of course that suitable circulating means are provided for both of the said media. j
The heat exchan e structure disclosed in v Figure 1 consists o a conventional'form of coal stove having as its means an outer casing 10 which confines the products of combustion rising from the fire-box 11, IThe casing is provided with a flue 12 for carrying off the products of combustion. Suitabl v located within the casin 10 is a shell 13 whic constitutes the means ofthe combination. The shell is provided with inlet and outlet conduits 14 and 15 by means of which a liquid ma be circulated through the shell. Suitably istributed over the outside of the shell 13 are a plurality of arched, heat absorb- 90 ing members 16 whlch project into the interior of the casing 10 so as to absorb heat from the products of combustion circulating through the heat exchange chamber (B) of' the combination above referred to.
Figure 2 discloses the manner of attaching the arched heat absorbin members 16 to the shell 13. In this embodiment of the invention, the arched members are cast integral with the shell 13.
--In kFigures 3- and 8 there are illustrated l two different forms of arched heat absorbing members. In Figure 3 the arched member 16 v -is constructed from solid, circular stock bent rectangular form to provide connectiony terminals 16. These two figures are intended to illustrate the ossibility of making the arched heat con ucting members of different sectioned material and of bending them into different-shapes. It is to be understood therefore, that the cross sectional shape o the material is unimportant and that the material vmay be bent into any desired shape just so terminals are provided by means of which the member maybe attached to a bod to be heated. The arched members, wit
their terminals connected to a shell or the like, .will form a closed circuit and. heat absorbed by the members will be conducted to the terminals and dissipated to the shell. It is believed advisable to note at this point that wherever the term arched is used throughout the specification and claims the same 1s intended to describe a member bent upon itself to provide relativel spaced connection terminals and as having or being 'without angles intermediate said terminals. In Figure 4 the heat exchan structure is illustrated as includin a she 17 employed for confining a liqui or the like, to be heated. This shell has suitable circulatin conduits 18 and 19. Located within the she 17 is a casing 20 adapted for confining the roducts of combustion rising from the gas urner 21 located below the lower open end of the said casing. Extendin from' the casing 20 to the outside of the s ell 17 is a flue 22 by means of which the roducts of.com-
` bustion may be discharged rom the heat exchange space (B) formed in the casing. In this structure, the wall of the casing 20sepa rates the medium to be heated, which is.
located exteriorly of the casing, from the heating medium which passes through the casing. Suitably connected to the inner surface of the casing 2O and projectin into the space'confined by said casing are t e arched heat absorbing and conductmg members 16. The arched members 16 in this embodiment of the invention are illustrated as being arranged in staggered relation with respect toeach other as distinguished from the arranging of the members in rows as illustrated 1n Fi ure 1.
Figure 5 lscloses the manner in which the arched members 16 are connected toY the cas,
In Figure 6 the meansl (A) includes an r 16 in Figure 3l is formed ofl outer metallic casing 24 which is provided with the insulating lining 25. Arran within-the space formed in the 24 is metallic shell 26 havin ranged around its periphery t e arched heat absorbing and conducting members 16. A gas burner 27 is located beneath the shell 26 and the products of combustion rising from the burner pass upwardly through the space (B) Ito be dlscharged from the latter through the flue outlet 28. Suitable circulating conduits 29 and 30 are provided for the shell 26. It will be noted that the arran ementof the arched heat absorbing and con ucting members 16 in this figure includes the location of some of the same at the lower end of the shell directly above the burner 27.
The heat exchange structures illustrated in `igs. 1, 4` and 6 are especially adapted for heating liquids, su h as water. It is to be understood, howeve that the basic combination above referred to is not limited in its useto heating a liquid forit is equally suitable for use in the generation of steam. For 'this reason, Figures 7 and 8 disclose steam generators.
In Figure 7, lthe heating medium confining means (A) includes a casing 30 having ankinsulating lining 31. Arranged within the space (B) confined by the casing 30 are a plurality of shells 32. Suitably connected to the exterior of these shells and projecting into the space (B) are the arched heat conducting and absorbing members 16. This ligure illustrates the arrangement of the members 16 on the respective shells so that they will'overlap each other. This arrangement of the arched members will further retard the passage of the products of combustion alon the shells 32 so that additional time is allowe for the absorption of the heat therefrom. Burners 33 are located beneath the shells 32 and the products of `combustion from these burners may be discharged through the flue 34. The conduits 35 and 36 are arranged to connect the shells 32 in parallel.
Figure 8 discloses a casing 37 which encloses a horizontal shell 38. The medium to be heated isv circulated through the shell and the products of combustion Will pass from the fire-box to this steam generator structure around the shell so as to be discharged through the flue 39. Arched heat conducting members 16 are suitably arranged around the periphery of the shell 38.
It is to be understood that the forms of this invention herewith shown and described are to be taken as preferred examples of the same, and that various changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjomed claims.
I claim: l i
1. In combination, means for confining a suitably armedium to be heated, means for confining a heating medium in heat exchange relation with the first mentioned medium, and 'a plurality of arched members arranged in staggered relation with respect to each other and aving the ends of their parallel leg portions connected to one of said means and projecting into the space confined by the other of said means.
2. A heat absorbing and conducting element for boilers and the like, oomprisin a conducting member adapted to be dispose in the heating zone and exterior of said boiler or the like, said member including an arched body having both ends thereof adapted to be connected to the member to be heated.
