Patented Jan. 21, 1936 PATENT OFFICE REFRIGERATJNG APPARATUS John Karmazin, Huntington, Ind., assignor to Karmazin Engineering Company, a corporation of Michigan Application May 7, 1935, Serial No. 20,203
4 Claims. (Cl. 257-255) This invention relates to refrigerating apparatus and more particularly to a novel heat exchange structure for use in refrigerating apparatus, as well as for other uses.
5 It is an object of the invention to provide a heat exchange device of the fin and tube type having a simple and reliable mounting frame therefor, by which the somewhat fragile fin and tube core of the device may be suitably sup- 10 ported.
. Further objects and advantages of the present invention will beapparent from the following description, reference being had to the accompanying drawing wherein a preferred form of the 15 invention is clearly shown.
In the drawing:
Fig. 1 is an end view of a heat exchange device embodying one form of the present invention;
Fig.2 is a side view of the structure illustrated 20 in Fig. 1;
F 3 is an end view of a heat exchange de e embodying a second form of the invention; and
Fig. 4 is-a side view of the structure illustrated 35 in Fig. 3.
Referring now to theform of the invention. illustrated in Figs. 1 and 2, there is provided a fin'and tube core II) which may be constructed in any suitable manner. The core I is illus- 30 trated as being formed in a'manner similar to that shown in the patent to Karmazin 1,591,323, issued Julyfi, 1926'. This form of core comprises a plurality of flat fins l2 having integral tapered tubular projections l4 formed thereon, the pro- 35 jections of each fin being telescoped into corresponding projections on adjacent fins to provide continuous tubes I6. Suitable return bends l8 are provided connecting the ends of adjacent tubes in a series flow circuit. Inlet and outlet 40 connections 20 are likewise provided at either end of the core.v The return bends 18 are preferably formed of a troughlike stamping 22 having a flange 23 on its periphery, together with a stamped closure plate 24 which has formed '45 therein a pair of tapered tubular projections 26' adapted to be telescoped with corresponding projections on the end fins l4. After the core structure is assembled together, a mounting plate 28 having openings 30 registering with the tubular o projections 14. of the fins I2 is slipped over the protruding projections on the end fin. The plate 28 has formed thereinupstanding lugs 32 which when the plate 28 is" ss'embled to the core I,
project perpendicularly. }to the plate 28. The a return bends l8 are then assembled to the core I I0 and the plate 28, with the tubular projections 26 telescoped over the tubular projections l4 of the outermost fin 12. The lugs 32 are then deformed downwardly as shown in the drawing to tightly clamp the plate 28 to the flanges 23 5 of the return bends l8. At the opposite side of the core, a mounting plate 34 is provided having openings 36 formed therein to register with the tubes [6. The return bends I8 at this side of the core l0 have their tubular projections 26 facing toward the core ID. The return bends are then assembled to the plate 34 and the lugs 32 are bent downwardly upon the flanges 23 of the return bends. The inlet and outlet connections 20 are inserted into the openings 36 at either end of the plate 34, and the plate together with the connections and the return bends I8 is assembled to the adjacent fin [2 in the manner shown in Fig. 2. The entire structure may then be bonded together by a suitable bond- 20 ing process, for example, soldering or copper hydrogen welding to provide a fluid tight heat exchange structure and to give mechanical strength to the device.
In the form of the invention illustrated in Figs. 3 and 4, the core l0 and the return bends l8 and connections 20 are formed similarly to the corresponding parts illustrated in Figs. 1 and 2. The mounting plates 40, however, are formed with large flanged openings 42 therein through which a substantial part of the body of the return bends It may be inserted. Openings 44 are also provided in one of the plates 40 through which the connections 20 may be inserted. In this form of the invention, the return bends l8 and connections 20 may be assembled to the core before end plate is assembled thereto. The plates 40 are then slipped over the ends of the return bends and connections 20 to take the position illustrated in Fig. 4. 0 The entire assembly may then be suitably bonded v to provide a fluid tight seal for the heat exchange device and to securely bond the plates 40 to the return bends I8 and the connections 20.
While the form of embodiment of the present 45 invention as herein disclosed constitutes a preform of a half cylinder, and a mounting frame for said structure comprising a plate extending adjacent said return bends and means formed in said plate engaging the Walls of said return bends.
2. A heat exchange structure comprising combination means forming a plurality of parallel tubes and transverse fins, return bends con necting the ends of adjacent tubes, said return bends including a hollow member in the gen eral form of a half cylinder, and a mounting frame for said structure comprising a. plate extending adjacent said return bends and means formed in said plate engaging the Walls of said return bends, said. frame being secured to said return bends by welding.
3. A heat exchange structure comprising in combination means forming a plurality oi pa allel tubes and transverse fins, return bends connecting the ends of adjacent tubes, said return bends including a hollow member in the general form of a 'naH cylinder, and a mounting frame for said structure comprising a plate ere tending adjacent said return bends and flanged openings formed. in said plate engaging the walls of said return bends.
4. A heat exchange structure comprising combination means forming a plurality of par allel tubes and transverse fins, return connecting the ends of adjacent tubes said. re-
said return bends, said plate having lugs formed therein adjacent said openings, said lugs being bent to engage said return bends and clamp the return bends between the lugs and the plate. JOHN KARMAZIN.
