Definitions

  • the invention relates to fins for heat exchangers with one or more rows of openings, through which the tubes of the heat exchanger extend (flat fins) or corrugated fins are arranged between the heat exchanger tubes, optionally with lamella cuts, for Increase in heat exchange as well as with folded edge, which has a free cross section in itself includes.
  • a manufacturing method for such ribs is also described.
  • a rib is known from US Pat. No. 1,752,879, which is a so-called flat rib.
  • the opposite longitudinal edges are not folded over and pressed together, as is the case with other solutions , but they close, as described, eyelet-like, a free cross-section one that has the shape of a drop in the publication mentioned.
  • This fringe education contributes to the fact that the incoming cooling air jets are swirled more intensely and the Increase heat exchange efficiency. Your should also have better rib stability can be.
  • the material of the ribs e.g. on extremely thin copper or aluminum tape is one when transported through the ribbed tool Is subjected to stretching, which, although it is in the elastic range, is not complete regresses.
  • the amount of stretching of the material depends on various factors can be quite different, so taking this fact into account when building the ribbed tools is not always a satisfactory solution. This is about deviations in the distances between the individual openings through which the heat exchanger tubes will later pass extend, in the range of 0.01 mm, with a long row of openings (tubes) can already lead to the fact that the tubes of the heat exchanger are no longer or only very much difficult to insert into the openings of the stack of fins.
  • corrugated ribs are known, which are arranged between the heat exchanger tubes and are usually connected to these tubes by means of soldering. With corrugated ribs it is known that the opposite longitudinal edges to give the corrugated fin greater stability. (e.g. EP 547 309 A1)
  • the object of the invention is to provide the ribs described in the preamble improve that the rib stability is further increased (for flat and corrugated ribs) and the deviations caused by the stretch remain in a negligible range, which should simplify the insertion of the heat exchanger tubes. (for flat fins) Manufacturing process should be characterized by simplicity and low cost.
  • Long metal material is arranged.
  • these are a wire, for example a copper wire, if the rib is made of copper sheet.
  • the wire must are not necessarily made of the same metallic material as the rib, but it is Because of possible corrosion it is an advantage if the same materials are used.
  • the cross section of the wire is preferably round and the free cross section of the edge is adapted to this round shape to preferably completely absorb the wire.
  • a Embodiment is characterized in that the wire cross section predominantly from that Edge hem is included. This has the advantage that a with the same stability narrower sheet metal strip can be used. Because such ribs are mass-produced acts, even seemingly small savings can lead to a significant effect.
  • any other cross-sectional shape of the wire for example a quadrangular or polygonal wire, fulfills this same purpose.
  • the length of the long material preferably extends over the entire length the rib.
  • the diameter of the long material is preferably in the range between 0.2 to 0.5 mm.
  • ribs The production of such ribs is very simple and can be done with minor changes on existing rib tools or on devices for rib production.
  • the wire now causes the Band elongation and the resulting deviation are significantly lower because of the wire or the two wires on the opposite edges of the rib, set the stretch of the Rip significant resistance. So in a stack of ribs the individual Align openings with higher accuracy than before in a straight line, so that the insertion the heat exchanger tubes are much easier, with less effort and fewer quality problems, can be done. In addition, the wire improves the stability of the entire rib due to the higher stiffness in the edge area, to an extent such as a slight increase the sheet thickness, associated with higher costs, could never be achieved.
  • only one edge of the rib can be formed with an enclosed wire his. In most cases, however, the two opposite longitudinal edges are the Rib have an enclosed wire.
  • Fig. 1 shows a rib tool 1, which is designed as a pair of rollers 2, the strip material 5 from the coil 4 - in this case a thin copper sheet - and the coils 6, on which Copper wire 7 is 0.4mm thick.
  • the wire ends are between the roller sets 13 or between the two-sided edge hem to be produced by means of the roller sets 13 introduced and enclosed in the folded edges 3 by means of the roller sets 13.
  • Synchronous with the transport of the copper sheet strip 5 from the coil 4 the copper wire 7 is from his Coils 6 unwound by the pair of rollers 2 pulling the strip material 5 and the wire 7.
  • the rib tool 1 right away behind the rib tool 1 or still within the tool 1 after the ribs 10 are fully completed, the same, along with the enclosed wires 7 cut off by means of a cutting tool 14.
  • the wires 7 remain in the folded Edges 3 and stiffen the ribs 10 substantially. Furthermore, the strip material 5 is no longer so greatly stretched, whereby the accuracy of the distances 11 between the punched openings 12th the rib 10 has been increased.
  • the fin tool 1 is a pair of rollers 2 in this case with which, as is well known, the openings 12 and cuts 13 are made in the flat ribs 10 become. However, it could also be a rib tool 1 for producing corrugated ribs. A corrugated fin 10 was therefore drawn symbolically at the left end of FIG. 1.
  • the rib tool 1 is a punching tool. It goes without saying that in this case jacking rollers must also be provided.
  • Fig. 2 shows an example of six different configurations of flat ribs 10, which are differ mainly in the arrangement of the openings 12.
  • An education (above right) was provided with lamellar cuts 13.
  • lamellar cuts 13 In all of these and other versions not shown there may be a wire 7 in the opposite folded edges 3.
  • the section 3 -3 was drawn in the lower right figure of FIG. 2. Of course it could have been drawn in any of the other images.
  • FIG 3 shows details of the arrangement of the wire 7 according to section 3 - 3 in the edge 3 in two variants A and B.
  • the section 3-3 should only show the edge 3, in which the wire 7 is located. It is also understood here that both the edge 3 of a flat rib 10 and the edge of a Corrugated rib is meant.
  • the wire 7 is completely enclosed by the edge hem
  • the second variant B shows that it is also possible to narrow the edge hem form and the enclosure only over a predominant part of the circumference of the wire 7 to be provided.
