, HEAT-CONDUCTING TUBE.
Application med :une 17, 1924. semi No. 720,512.
In cert-ain prior applications, Nos. 642,427l
- which is in Contact with the water or other fluid in the tube.
The present invention provides a unit and a method of producing the same from which such boiler walls andthe like may be built. The accompanying drawings illustrate embodiments of the invention.
` Fig. 1 is a horizontal section of a side wall of a. boiler built with the tubular units of the invention;
Fig. 2 is an enlarged perspective view of one of the tubes.
In another application pending concurrently herewith Serial No. 715,369, filed May 28, 1924, there is .described a unit for the purpose stated with flanges of certain shapes and methods of'production and application. The present application is directed to a specifi'- cally different unit.
The boiler wall has on the inside a @reen composed of tubes 1 with lateral fins or flanges 2 overlapping each other. Outside of this screen is the usual wall made of refractory brick 3, tiles 4 of non-conducting material and an outer shell 5 of sheet metal. As illustrated in Fig. 2 the flanges 2 are composed of a plate or flat bar extending continuously through the tube, so that the opsite flanges are integral with each other. he tube is made of semi-circular segments with their edge-s brought to register at opposite sidespof the flat-plate and butt Welded at the points of contact 6.' The cent-ral portion 7 of the plate conducts the heat from the flanges 2 directly into the water or other fluid 1n the tube and thus provides a very efficient structure. The inner part 7 of the plate 1s provided with slots 8 at intervals so as to prevent circulation of the water on opposite sides of the-plate.
'As stated in application No. 715,369, above 50 referred to, the tubes may be of vario-us shapes and may be of ordinary low carbon steel, while the flanges may be made of spep lal alloys o-r specially coated to resist oxida- While we have described with great particularity of detail certain embodiments of our invention, yet it is not to be understood therefrom that the invention is restricted to the particular embodiments disclosed. Various modifications may be made by those skilled in the art witho-ut departure from the invention as defined in the following cla-im.
What we claim is:
A heat conducting unit comprising a tubular member made up of a plate and of hollow segments welded to opposite side-s of said plate vto provide a tube with lateral flanges extending beyond the tube and eX- posed to the surrounding medium, the part of the plate within the tube being apertured to permit circulation between opposite sides thereof. t
In witness whereof, we .have hereunto signed our names.
