  • the invention relates to a fin for a heat exchanger, the one made of tubes and across these ribs composite ribs / tube block, with several Pull-throughs in the assembled state of the fins / tube block pick up the tubes with each thread spacer for a uniform, corresponding to the rib division Positioning to the respective adjacent rib, as well as a method for producing rib passages in such ribs, whereby from a flat rib plate Forming a collar forming the passage is issued becomes.
  • Such a rib and such a method are from DE 44 04 837 A1 known.
  • the tubes of the fins / tube block Passages of the ribs with spacers in the form of pronounced noses distributed over the circumference of the passages.
  • To produce the passages of the ribs are in a first method step from a correspondingly level Rib plate in the area of each passage punched out, rags being cut free at the same time, in the in a subsequent process step as Spacer serving noses are impressed.
  • the object of the invention is a rib of the aforementioned Art to create that with simplified manufacturability at least equally good spacer functions for achieving an even rib division like the state of the Technology enables.
  • the object of the invention is furthermore to create a process of the type mentioned that one reduced manufacturing effort to create the ribs guaranteed.
  • each passage preferably has two on opposite Support edges arranged on the long sides of the passage on, which correspondingly turned outwards are.
  • the flat contact surface formed by the support edges runs parallel to the rib plane.
  • the at least one support edge is with at least one ear-like protruding coplanar to the outside Provide tab.
  • the ear-like tab enlarged the flat contact surface for the adjacent rib, see above that a further improved block assembly of the fins / tube block is achievable.
  • the task is solved in that first at least one cut in the flat ripper plate is introduced, and that subsequently through the separating cut formed cut edges are formed into the collar.
  • the invention Process no waste as there is no punching Creation of through openings is needed. The passages are rather created on the basis of simple separating cuts. Since there is no punching waste, the necessary ones are eliminated Operations for the removal and disposal of the Punching waste. This makes the production of the Ribs can be achieved.
  • the pressing tools can also be simplified be produced as no measures are taken be a removal of the punching waste from the Achieve punching areas.
  • the separating cut is made on his opposite ends forming ear-like Straps curved.
  • the curved course of the separating cuts ensuring the formation of the ear-like tabs that no tearing in the subsequent forming stages the ribbed plate is made at the level of the separating cut. Consequently an improved producibility of the rib passages is achieved.
  • Ribs 1, 1a as cut out in FIGS. 1 and 10 are part of a fin / tube block for one Heat exchanger, especially for use in one Motor vehicle, a variety of parallel to each other aligned ribs 1, 1a each with a variety of Provided parallel passages 3, 3a are a multitude of in a row in parallel side by side Take running pipes.
  • the tubes are shown Embodiment designed as flat oval tubes, the passages 3, 3a are correspondingly identical are designed.
  • the one composed of fins 1, 1a and tubes Ribs / tube block becomes mechanical in a manner known per se added, the passages 3, 3a of the superimposed Ribs 1, 1a tightly enclose a tube.
  • the passages 1, 1a of the ribs 3, 3a each protrude rectified from the associated rib and form for the overlying rib 1, 1a spacer, so that a uniform rib division of the ribs / tube block achieved becomes.
  • the basic structure of a fin / tube block, such as it has been previously described, including mechanical Joining of the fins / tube block is detailed in DE 44 04 837 A1 described and disclosed by drawings, see above that referred to this document for a more detailed explanation becomes.
  • the rib 1 has a flat rib plate 2, whose longitudinal edges each with one Edge groove 5 are provided. Along the flat rib plate 2 are aligned parallel to each other at regular intervals Passages 3 provided, the passage opening to the The outer contour of flat oval tubes is adapted. Between neighboring passages 3 are known gill fields 4 provided, for their further explanation also on the DE 44 04 837 A1 is referred.
  • the passages 3 are identical designed to each other. Each passage 3 has a circumferential, perpendicular to the one that defines the rib plane Rib plate 2 on one side of the collar 9, on in the area of the opposite long sides of the collar 9 Connect two supporting edges 6 that are set out at right angles to the outside.
  • the surface of the support edges 6 runs parallel to the rib plane formed by the rib plate 2. in the Transitional area between the collar 9 and the support edges 6 are on both long sides of the collar 9 three in uniform Intervals arranged lugs 7 stamped.
  • the Noses 7 are analogous to those described in DE 44 04 837 A1 Noses so pyramid-shaped that they are in the Level of the support edges 6 has a triangular cross section form.
  • the lugs 7 are on the opposite long sides each thread 3 is mirror-symmetrical to a central longitudinal plane each passage 3 arranged so that each long side the passage 3 and thus each supporting edge 6 each three lugs 7 are assigned.
  • the lugs 7 have one Spacer function, which for itself from DE 44 04 837 A1 is already known, a stiffening function for the two support edges 6 on since they are a for the support edges 6 Form web-like support function.
  • the rib 1a according to FIG. 10 essentially corresponds to the rib 1, as previously described. Same parts of the Rib 1a are therefore with the same reference numerals, only designated with the addition of the letter a. Only one Difference in the rib 1a to the rib 1 according to FIG. 1 it is that the passages 3a of the rib 1a on diagonally opposite End areas of the opposite support edges 6a each have an ear-like tab 10 which is coplanar protrudes to the support edge 6a to the outside.
  • the ear-like tab 10 has manufacturing reasons, as described below will be.
  • a separating cut 8 (FIGS. 2a and 3a) is made in the fin plate 2 at the level of the respective pipe pitch and thus the later positioning of the passages 3 transversely to the longitudinal axis of the fin plate 2, which is made by a suitable cutting tool with simultaneous support of the rib plate 2 is achieved.
  • the support edges 6 and the lugs 7 are created according to FIGS. 2b and 3b.
  • a stamping die S 1 which acts at right angles to the ribbed plate and which interacts with a die (not shown ), is provided as a corresponding forming tool.
  • the die S 1 has a blade-like shape with a cross section that corresponds to the course of the support edges 6 in FIG. 2b.
  • the embossing die S 1 also has embossed edges of this type on the side in such a way that the lugs 7 are embossed by the shaping step together with the angling of the supporting edges 6.
  • the support edges 6 protrude upward at right angles to the rib plane formed by the rib plate 2.
  • the bottom of each nose 7, which is triangular in cross section extends inward and upward at an acute angle to an underside of the ribbed plate 2 to the respective supporting edge 6.
  • the cut edges formed by the separating cut 8 are thus flared up and expanded to form the support edges 6. The widening must be carried out carefully so that the separating cut 8 does not tear at the opposite end regions.
  • a further widening of the passage opening whereby increased by a further, opposite the stamper S 1 in the width stamper S 2, a peripheral, in this process step or obliquely upward is Upset and thus created conically upwardly tapered collar 9 .
  • the die S 2 is provided with a correspondingly elliptical and tapered embossing contour.
  • the embossing die S 2 is used for reshaping such that additional material of the rib plate 2 is pressed obliquely upward in the area of the passage opening, which results in the circumferential collar 9 below the lugs 7 and the support edges 6.
  • the collar 9 tapers upwards towards the free end of the passage opening and the two supporting edges 6 protrude at an angle upwards and outwards at right angles to the collar.
  • the end contour of the passage 3 is achieved by means of a stamping die S 3 which is widened in cross section, the collar 9 being pulled through in such a way that its circumferential wall is turned upwards at right angles to the rib plane.
  • This process step documented with reference to FIGS. 4b and 5b, comprises the finished passage, the supporting edges 6 projecting outward at right angles to the collar 9.
  • the process for producing the passages 3a from the ribbed sheet 2a corresponds to the rib 1a according to FIGS. 6 to 10 essentially the manufacturing process described above, so that only the differences to the already described manufacturing process is discussed.
  • the Passages 3, 3a the further completion of the ribs 1, 1a achieved by the gill panels 4, 4a and the edge grooves 5, 5a are impressed accordingly.
