METHOD OF MANUFACTURING HEAT RADIATORS Filed Oct. 21,.1941
INVENTQR Elbert. BIZ-31 1.725
BY v/W- 4r ATTORNEY I Patented 1945 METHOD-OF .MANUFACTU RDIG HEAT RADIATORS Gilbert 0. Barnes, Mancheste), Conn., assignor to United Aircraft Corporation, East Hartford, Conn, a corporation of Delaware 1 Application October 21, 1941, Serial No. 415,911 2 Claims. (01. 29-1573) This invention relates to improvements in heat radiating structures and has particular reference'to an improved fin construction for a heat dissipating or radiating body such as an'aircooled intemal-combustion engine cylinder.
An object of the invention resides in the provision of an improved heat radiating body of the character indicated having fins formed of two or more metals arranged in mutually bonded layers.
A further' object resides [in the provision of an improved heat radiating body of the character indicated including a tubular body and heat radiating fins thereon in which the flnned surfaces are formed of a metal diflerent from the metal of which the body is formed and in an improved manner of securely attaching such flns to the outer surface of the body. 7
Other objects and advantages will be more particularly pointed out hereinafter orwill become apparent as thedescription proceeds. I
In the accompanying drawing, in which like reference numerals are used to designate similar parts throughout, there is illustrated a suitable mechanical embodiment forthe purpose of disclosing the invention. The drawing, however, is for the purpose of illustration only and is not to be taken as limiting or restricting the inven-- tion since it will be apparent to those skilled in the art that 'various changes in the illustrated In the drawing, Fig. 1 is a transverse sectional view of a suitable metal blank for a cooling fin.
Fig. 2 is a transverse sectional view similar to Fig. '1 showing the fin produced from the blank illustrated in Fig. 1, and
layers provides an easy path for the conduction of heat through the metal.
The blank 10 may comprise an apertured member of any suitable shape such as the illustrated.
annular member of circular, or generally circular, shape having a central aperture surrounded by a struck up flange ill of a depth'approximate-* ly equal to the desired fin spacing. This blank may be formed in a suitable stamping machine by a method well known to the art. After the blank has been formed, as, illustrated in Fig 1, the outer. metal coating is removed from the inside of the flange It by a suitable machining or grinding process to provide a straight walled aperture of substantially the same size as the outer surface of the body upon which the flns are to be secured, the finished surface of the flanged portion of the fin being indicated at 20 in Fig. 2 and constituted by the metal of the intermediate or steel layer. The fins, as gen! erally indicated at '22 in Figs. 2 and 3, are then secured upon the exterior of the heat radiating body such as a steel walled engine cylinder barrel 24 in such a manner that the spacing is determined by the contact of the ends of the flanges IS with the adiacentfins.
The fins may be secured to thecylinder barrel by'a suitable brazing or welding operation forming a fused metallic bond which will provide good heat transferring qualities between the cylinder barrel and the fins. Such an operation is particularly facilitated by the fact that the contacting surfaces of the cylinder barrel and the fins are both of substantially the same material thus obviating the difiiculty of attempting to secure flns of one material to a cylinder bar-.
. rel of a different material. Since in the illus- Fig. 3 is an elevational view of a finned heat,
radiating body aportion being broken away and shown in section to better illustrate the construction thereof.
Referring to the drawing in detail, the fln blank, iparticularly illustrated in Fig. l and gentrated example hereinabove described, the cylinder barrel is of steel and the portions of the fins contacting the outer surface of the cylinder barrel are also of steel, 9. suitable bond between these surfaces can'be readily obtained.
While a combination of steel 'and aluminum 'flns with a steel heat radiating body has been particularly described for the purpose of disclosing the invention, it is to be understood that the invention is not limited to the particular metals mentioned but that the improved construction may be readily applied to other combinations of different metals.
While a suitable mechanical embodiment for the purpose of disclosing the invention has been hereinabove described and illustrated in the accompanying drawing, it is to be understood that the invention is not limited to the particular embodiment so described and illustrated but that such changes in the size, shape, construction and arrangement of the various parts may be resorted to as come within the scope of the sub- J'oined claims.
Having now described the invention so that others skilled in, the art may clearly understand the same, what it is desired to secure by Letters Patent is as follows:
1. The method of manufacturing a heat, radiator which comprises, forming annularfln's from a metal sheet having an-mtemi'ediat'e layer of metallic material and outside layers of a different metallic material, forming a central flange in each fin, removing the layer of said difierent material from the internal surface cfeach flange to expose the material forming the intermediate layer and form a. straight wall opening in the flange' having the sameshape and fitting closely and fitting closely over the tube on which said fins are to be mounted, assembling said fins on said.tube,, and uniting said flanges to said tube by a fused metallic bond. 7
