UNITED STATES PATENT OFFICE HEAT EXCHANGE ARTICLE Application led April, 4, 1930. Serial No. 441,607.

This invention relates to a method of forming, and the article to promote heat exchange'. An object of the invention is to provide for a I 'very simple and inexpensive method of 6' 'forming heat exchange elements to be used for steam condensers, refrigerant gas, radiators for automobiles, aeroplanes, air condltionmg 1n all kinds of buildmgs, heat systems, and for all heat and cooling systems wherein exchange is desired.

Another feature of the invention is toprovide a heat exchange conductor that is very strong, compact and durable, thoroughly reliable for its intended purpose, very simple in its method of assembly, facilitating increased production, and that is comparatively inexpensive to manufacture.

With the foregoing and other objects in view, the invention consists of a novel construction, combination and arrangement of parts aswill be hereinafter more specifically described and illustrated in the accompanyy ing drawings, wherein is disclosed an emtratingan application of one formv of the' fins therewith.'

Fig. 2 is a perspective view thereof being assembled,

Fig. 7 is a fragmentary side elevation of the Huid conducting member showing a modilied form of fin and fin attaching means, also in side elevation,

Fig. 8 is a fragmentary plan view of the fluid conducting member and the fin construction shown in Fig. 1 of the drawings, with a modified form of fin attaching means, Fig. 9 is a fragmentary top plan view ofthe stamped metal in attaching means, illustrated in Fig. 8, prior to the attachment thereof, J

Fig. 10 is a transverse, vertical detailed section taken substantially on the line 10-10 of Fig. 8,

Fig. l1 is a transverse vertical detailed section through a fluid conducting member with the iin attaching means illustrated in Fig. 12,

Fig. 12 is a fragmentary plan view of a modified form of iin attachingv means, prior to the assembly thereof, and

Fig. 13 is a fragmentary perspective view of the anchor bars associated with the iin attaching means, shown in Figs. 9 and l2.

The invention in its broadest aspect comprehends the method of constructing and the resulting article of manufacture, for exchanging heat from a confined body of iuid to a free body of iiuid or vice versa. The fluid conducting member, as will hereinafter appear may be polygonal or circular in cross section, and of any desired lineal configuration, since it would be a simple matter of application to form the radiating fins, with a contacting surface contour and lineal configura-A tion to meet the shape of the cross section and conliguration of the conducting memler.

The conducting member and radiating fins are preferably of metal such as brass, copper, steel, aluminum or alloys thereof, or any other ductile rigid material capable of being fabricated by the present method.

Furthermore, it is to be understood that ing or conducting member, in which isenclosed'a fluid, either at rest, or 1n motion.

This member 14 may be one of a plurality of' posed at faces 15, 16. The chamberv 17 interiorly of the conductor 14 is entirely closed andy in this chamber is the one fluid either at rest or in motion, with which it is desired to effect a heat exchange, with the fluid surrounding the outside of this conductor member.

In allforms of the invention, the two series of radiating fins, are indicated at A and B.

All of the radiating fins are preferably formed of bendable metal strips 18, 19 of substantially the same width as the faces 15, 16 of the conducting member 14, to which they are attached.

v These strips are of suicient rigidity to sus-1 tain their own shape after they have been crimped to the desired shape.

In the form of the invention shown in Figs.

1, 2, 3, 8, 10 and 11, the metal strips 18, 19

are each crimped transversely into a series of continuous substantially U-shaped crimps 20,21 having straight legs and crown portions with alternate crimpsfreversed with respect to intermediate crimps, thereby providing inset pockets 22, 23, on each series.

In the form of the radiating fins A, B, shown in Fig. 7, the strips 18, 19 are each crimped transversely into a series of continuous U-shaped crimps 24, 25, having curved crowns and straight legs.

rIhe alternatg crimps are also reversed Wit-h respect to lntermediate crimps to pirovide inset pockets 26, 27 with respect to the intermediate crim s.

In the form o the radiating fins A, B shown in Fig. 5- of the drawings, the strips 18, 1'9 are each formed transversely with a continuous series of V-shaped crimps 28, 29 havindg alternate crimps of each series reverse Vwith respectto intermediate crimps, to provide alternate pockets 30, 31.

In the form of the ,radiating fins A, B, shown in Fig. 6 of the drawings, lthe'strips 18, 19 are each crimped transversely with a continuous series of crimps 32, 33 in the form of loops with alternate loops reversed with respect to intermediate loops to provide a1- ternate pockets 34, 35.

In view of the foregoing, ittherefore follows that the single strips or webs of metal in `either-of the orms shown are very economically fabricated into a` series of continuous, spaced outstanding projections, that by reason of their'continuous nature and intervening pockets, present the maximum heat exchange area and a very inexpensive means for anchoring the fins, to the conductor 14.

All forms of the series of fins A, B, after crimping are lplaced on the conductor 14, the one series A superimposed on the face 15, and the other series, B depending from the other face 16. The series are so arranged that the pockets and the projections on the one series A are in alinement with the otherseries B.

Then a roundI strand of wire 36 'as shown in Figs. 1, 2, 5, 6, and 7 is wrapped about ythe conductor 14 and seats in the pockets of each series holding each series into contact with the conductor at the inner ends of the crimps. The wire 36 is wrapped in the continuous coil the entire length of the conductor and fins, alternating from one pocket diagonally to another as shown in Fig. 7' of the drawings.r On the other hand, a fiat strip 37 'as shown in Fig. 3 may also be used to advantages in the attachment of the series -of fins having the crimps formed of straight crowns, and legs. This Hat strip 37 gives a better anchorage for those series of fins having the straight crowns. y

It will be understood that the fiat strand 37 is Wound the same as the round' strands 36 and described above.

I have other fastening means for the series of fins A, B, as shown in Figs. 8, 9, and 10. This fastening means is formed `of 'a stamped piece of metal indicated vgenerali at 40 having a central longitudinally exten ing rib 41 projecting. laterally from each side of which are a series of transversely extending, longitudinally spaced slat strips l 42 and 43 which in turn merge at their outer ends in the respectivey Hat strips 44, 45 respectively.

To use the fastening means 40, the longitudinal rib 21 is su erimposed on the end of I the conductor mem er 14 and the strips 44, 45 bent downwardly over the series of crimps A, B with the series of spaced ribsl 42, 43 seating in the pockets of the crimpsthereblyl7 holding the.' series of crimps in contact wit the opposed faces of the conductor member 14.

Then end strips .44, 45 are brought into abutting vrelation with each other and the elongated anchor bars 46, 47 are disposed on' the outer faces of the strips, and the bolts 48 extending throu h apertures in the anchor lars and the strips together, about the conuctor.

It will be a parent that the fastening' Another form of fastening means for the"I series of crimps is shown in Figs. 11 and 12, and indicated generally at 49. This fastenl ing means consists of a central longitudinal channel bar 50 formed with a series of notches 51, 52 in the upper edges of each leg.

' other side of the A series of transversely extending longitudinally spaced round wires 53 project laterally from one side of the channel bar and another seres 54 projects laterally .from the channel bar. The inner ends of each series of wires 53, 54 extends through the respective series of notches 51, 52 and are anchored to the channel bar 50 by means of knots 55, 56 on the inner ends thereof.

To use the fastening means 49, the channel bar 50 is disposed with the inner face of the web against the inner end of the conductor member 14 as is clearly shown in Fig. 11. The series of wires 53, 54 are then wrapped over the series of crimps A, B seating in the A pockets between the crimps and the ends of the wires crimped between the flat anchor `bars 46, 47 by the bolts 48 similar in all respects to the means of anchoring the fastenin means 40.

it is thought that the present embodiment of the invention' has been disclosed in considerable detail, merely for the purpose of.

exemplication, since in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention and theV above description. It is to be understood that by describing in detail herein any particular form, structure or arrangement, it is not intended to limit the invention beyond the terms of the claim or the requirements of the prior art.

Having thus described my invention, what I claimas new is A heat exchange element comprising a tubular member, a number of strips, each crimped transversely to provide a plurality of recesses, with bottom walls of alternate recesses contacting the tubular member, and.

a fastening strip spirally wound around the recess strips and tubular member and engagin the inner walls of said alternate recesses.

n testimony whereof I ax my signature.
