BAND FOR HEAT EXCHANGE Filed April 5, 1967 INVENTOR. Sum/v J/W/mv 4/, I I v ATTORNEY v United States Patent 3,384,167 BAND FOR HEAT EXCHANGE Simon Javkin, 160 West End Ave., New York, NY. 10023 Filed Apr. 3, 1967, Ser. No. 628,044 3 Claims. (Cl. 165171) ABSTRACT OF THE DISCLOSURE A wall forming band for heat exchange formed of an extruded elongated body having an integrally formed tabular conduit and having flanges on the ends thereof. The band is wound in a spiral fashion on a suitable mold with the flanges of adjacent sections interlocking to form a heat interchange with an integrally formed conduit. The mold is removed after the bending therearound and the flanges are flattened together.
This invention refers to an extruded wall-forming band for heat exchange, and to the method of use thereof to form a heat exchanger and, more especially, to an integral element which, by winding or bending, makes it possible to form walls or inclosures for heat exchangers, such as evaporizing chambers or condensers or boilers, etc.
One of the principal advantages of this invention is the fact that the integral band in itself contains a closed and continuous conduit for the passage of a fluid and thus avoids fastening additional tubes to the heat exchanger by welding or by any other known means.
Another advantage is the fact that this invention establishes a means for lateral union which makes it possible to obtain, without any other accessories, a tight interconnection to form continuous walls either open as in the case of condensers or laterally closed forming a chamber as in the case of evaporizers or boiler heating chambers, etc. Thus it is evident that the method of manufacturing in accordance with this invention is highly advantageous in comparison with the prior conventional methods of manufacture.
Besides, because of its peculiar structure, the invention insures a greater working efiicacy and at the same time prevents any possible fluid leakage.
Moreover, because of the very conception of the lateral uniting of the flanges of the band to form a continuous structure, it is possible to obtain a smooth interior surface, which is very important when dealing with evaporizing or boiler heating chambers.
Still further objects of the invention reside in the provision of a band for constructing a heat exchanger that is especially strong because of its novel configuration, durable, capable of use in forming heat exchangers of various sizes and shapes, and which is economical in production.
These, together with the various ancillary objects and features of the invention which will become apparent as the following description proceeds, are obtained by this invention, a preferred embodiment being illustrated in the accompanying drawing, by way of example only, wherein:
FIG. 1 is a perspective view illustrating a section of the integral wall-forming band for heat exchange in accordance with the concept of the present invention;
FIG. 2 is a perspective view of the first stage in the process of manufacturing a structure for heat exchange. In this stage there is obtained by extrusion the band that constitutes the basic element of the structure;
FIG. 3 is a perspective view which shows how the integral band is wound around .a mold in order to form a chamber by joining its corresponding lateral edges;
FIG. 4 is a perspective view which shows how a cham- 3,384,167 Patented May 21, 1968 "ice her of walls for heat exchange has been formed by winding a band, and how the junction of the joined lateral edges is flattened all along the winding thus leaving a substantially smooth continuous interior surface;
FIG. 5 is a sectional detail view illustrating the connection between the edges of adjacent sections of the band; and
FIG. 6 is a sectional detail view of a modified band.
With continuing reference to the drawing, wherein like reference numerals designate similar parts throughout the various views, reference numeral 10 designates a band which is extruded of any suitable material and of a suitable width and in which is defined a substantially plane body 11 of the central part of which forms on one of its surfaces a lengthwise protuberance which in turn forms a closed conduit 12 leaving the opposite surface of the body 11 flush and without any projections.
One of the marginal edges of the band 10 has an inverted substantially L-shaped flange 13 bent back over the band nearly parallel on the same surface on which the conduit 3 is formed, whereas the other lateral edge has an inverted substantially U-shaped flange 20 with the upper portion being closed, which folds back inwardly, including bent portion 14 normal to the band 10 and on the same surface of the band 10 on which the conduit 12 is found. The flange 20 includes a parallel span 15 from which is projected an outer margin portion 16 that ends in a folded flange portion 17 which folds back inwardly. Between the outer surface of the flange portion 17 and the plane surface of the band 10, there is a difference in height that approximately corresponds to the thickness of the body 11.
As can be seen from what has been explained and illustrated, the method of manufacturing a structure for heat exchange with the band 10 of the invention is very simple. In the embodiment illustrated, the first step in the manufacture of the band 10 is obtained in the way shown in FIGURE 2, that is, by molding, in aluminum or other similar material, a continuous band 10 by means of extrusion and with the characteristic features already pointed out.
Once the band 10 is extruded, it is wound spirally around the mold 18 and the flange 13 is simultaneously introduced into the channel formed by portions 15, 16 and 17 of the adjacent flange of an adjacent winding. In this way a chamber generally indicated at 30 with closed and continuous lateral walls is obtained.
Then, the lateral junctions which are initially relatively loose to permit joining of flanges are flattened by hammering, application of pressure, or other adequate conventional means. In this way the junction between the turns of the band 10 is made more perfect and a chamber 30 is formed, the inner surface 32 of which is substantially smooth and its outer wall has a defined spiral with a continuous conduit 12 that goes round the chamber 30. Of course, if considered desirable, the surfaces may be welded or sealed.
If it is desired to obtain an open structure in which a continuous conduit is formed, especially suitable for condensers, the band 10 is bent parallel to itself on the same plane, to do which recesses and lateral cuts can be made in the portions corresponding to the ends of the foldings, and the said sections are arranged adjacently, thus forming the union joint in the way described for every winding, and later the junction is flattened in such a way that it leaves one surface of the structure smooth and the other surface overrun by the continuous sections of conduits bent parallel to itself on the same plane.
A latitude of modification, substitution and change is intended in the foregoing disclosure, and in some instances, some features of the invention will be employed without a corresponding use of other features. Accordingly, it is 3 4 appropriate that the appended claims be construed broadly 3.
