Definitions

  • the invention relates to a heat exchanger, comprising flat and narrow sides having flat tubes and ribs which form a block and having the further features listed in the preamble of claims 1 and 2, respectively.
  • the heat exchanger described in the preamble is known, for example, from DE 198 19 247 A1 and also from WO 2006/133748 A1.
  • the projections provided in the first-mentioned reference correspond to openings in the tubesheets.
  • a provisional cohesion of the items is provided before performing the soldering process.
  • the effort for soldering auxiliary device can therefore be reduced.
  • a certain disadvantage of this heat exchanger is that there is still a significant overhang of the tubesheet over the ribbed flat tube block which could be considered unnecessary space requirements.
  • the ratio of the cross-sectional area occupied by the flat tubes is not optimal in comparison to the entire cross-sectional area of the heat exchanger or its tube plates, so that improvements are possible with regard to efficient space utilization of the heat exchanger.
  • this heat exchanger could be regarded as insufficiently equipped for thermal cycling.
  • projections have been provided, which are, however, inserted into the ends of the flat tubes, in each case in the region of the narrow sides thereof. It has already been proven that this heat exchanger has considerable advantages over other solutions. However, it is desirable to have suitable back-up solutions available, for example in the event that the heat exchanger known from this reference should not be able to cope with the most extreme requirements with regard to the thermal cycling.
  • the object of the invention is to provide heat exchangers available which in part have an even higher resistance to Expect thermal cycling or at least sufficient resistance, with relatively good thermal performance.
  • a production-friendly, in particular a flexible design can be assumed.
  • the narrow sides of the flat tubes at the longitudinal edges of the tube sheet abutment and because the projections engage in the longitudinal edges, the projections sit between the flat tubes and border the narrow sides the resistance to thermal cycling was comparatively further improved, because the particularly vulnerable area of the narrow sides of the flat tubes was significantly strengthened, and amplified without additional, the cost and weight-increasing, reinforcing parts must be used, as it has been proposed several times in other publications.
  • each Tlachrohrende is bordered or supported in the narrow sides of two projections, so that the improvement of the resistance is traceable.
  • the projections may indeed have been known in the prior art, but are the prior art, the projections in corresponding openings (slots) in the tube sheets and provide Therefore, according to the proposal, on the other hand support the projections according to claim 3 at the bottom of the deformed longitudinal edges or they are trapped therein. Openings in the tube sheets are not provided, which is why the mentioned risk is eliminated by the invention.
  • a second solution according to the invention provides that the narrow sides of the
  • the tube sheet and the collection box are either one piece or at least formed in two pieces.
  • Embedding are spaced grooves or slots.

  • Figs. 12 and 13 show an embodiment with a one-piece
  • FIGS. 14-17 show a further embodiment with grooves in the edges of the collecting box, which serve for embedding the narrow sides of the flat tubes.
  • the embodiments shown are directed to completely made of metal, preferably from suitable aluminum sheets, producible heat exchangers, for example for use in motor vehicles.
  • the aluminum sheets have appropriate solder coatings. After the manufacture and assembly of the individual parts of the heat exchanger and after appropriate pretreatment, these are then joined in a single CAB brazing process (not shown).
  • the heat exchanger consists of wide and narrow sides flat tubes 1 and ribs 2, which form a block and, in the embodiment, of two tube sheets 3 each having at least two deformed longitudinal edges 30 and two collecting tanks 4. In the illustrations, only one side of the heat exchanger has been shown.
  • the openings 31 must be formed in the tube sheets 3 to directly on the longitudinal edge 30 zoom, which is best seen in FIGS. 6 and 7, because there in the foreground one of the openings 31 to see is, in which no flat tube 1 is yet.
  • the formed longitudinal edges 30 have been formed as lying below the tube bottom surface 35 channel 30.
  • the above-mentioned projections 41 engage at the edges 40 of the collecting box 4 in the longitudinal edges 30, wherein the projections 41 sit between the flat tubes 1.
  • two projections 41 each support a flat tube 1 on its broad sides, but directly towards the narrow sides, from.
  • the flat tubes 1 and the ribs 2 are combined to form a flat tube ribbed block.
  • the tube sheets 3 with deformed longitudinal edges 30 are placed at the ends of the flat tubes 1.
  • the collecting boxes 4 are set with their edges 40, on which projections 41 are arranged at intervals, to the edges 30 of the tubesheets 3.
  • the longitudinal edges 30 of the tubesheets 3 are brought into contact with the narrow sides of the flat tubes 1 in the course of the so-called "winding up" of the tubesheets 3.
  • the projections 41 are in contact with the longitudinal edges 30 and with the Flat tubes 1 brought, the projections 41 are inserted into the spaces between the flat tubes 1.
  • the projections 41 having longitudinal edges 40 of the collecting tank 4 are internally applied to the edges 30 of the tube sheet 3, wherein the projections 41 are inserted into the spaces between adjacent flat tubes 1.
  • the longitudinal edges 30 have been provided with a suitable bevel 33 or the like, so that the edges of the collecting box 4 can be more easily inserted into the longitudinal edges 30 of the tube bottom 3.
  • auxiliary devices are used which either in principle do not differ from the hitherto customary auxiliary devices or which can be modeled by the person skilled in the art.
  • Figs. 1 and 6 further show, it has been provided in these embodiments to reshape not only the longitudinal edges 30 of the tube sheet 3, but also their transverse edges 32.
  • Executions remain the transverse edges 32 substantially without deformation, so that the tube sheets 3 can be produced from endless metal strips, which are cut to the required length.
  • side parts then close the frontal openings of the collecting tanks 4.
  • Fig. 1 a further alternative was merely indicated.
  • the suggestion consists in only two slots 36 in the opposite longitudinal edges 30 of the tube bottom 3.
  • the slots 36 can be understood as a continuation of the openings 31.
  • such slots 36 are arranged.
  • the narrow sides of the flat tubes 1 sit in these slots 36, so that they are preferably flush with the outside of the formed longitudinal edges 30.
  • the longitudinal edges 40 of the collecting box 4 are then attached from the outside (not shown) to the longitudinal edges 30 of the tube bottom 3.

  • This tube sheet / collecting box has a connecting seam, for example a solder joint 45, which is located on the central longitudinal axis of the heat exchanger.
  • the narrow sides of the flat tubes 1 bear against the inside of the longitudinal edges 40 of the tube bottom / collecting tank.

Abstract

L'invention concerne un échangeur de chaleur constitué de tubes plats (1), présentant des côtés larges et des côtés étroits, et d'ailettes (2) qui forment un bloc, ainsi que d'au moins un plateau à tubes (3) / récipient collecteur (4) présentant au moins deux bords longitudinaux (30, 40) façonnés opposés. Cet échangeur de chaleur se caractérise en ce que les bords (40) du récipient collecteur (4) présentent des parties saillantes (41) espacées et en ce que les côtés étroits des tubes plats (1) sont placés contre les bords longitudinaux (30) du plateau à tubes (3) ou du récipient collecteur et sont reliés à ceux-ci, les parties saillantes (41) s'engageant dans les bords longitudinaux (30) et venant se loger entre les tubes plats (1). L'invention concerne également un procédé de production correspondant. Cette invention permet notamment d'obtenir des échangeurs de chaleur pouvant être produits à faible coût et présentant une haute résistance aux chocs thermiques.
