Definitions

  • the invention relates to a heat exchanger, for example an exhaust gas heat exchanger, having the features of the preamble of the claims 1, 2, 3 or 7.
  • An exhaust gas heat exchanger is out of the EP 1 348 924 A2 as well as from the EP 1 544 564 A1 known. He essentially fulfilled his task during the implementation. Recently, however, the exhaust gas mass flows, including the exhaust gas temperatures of the motor vehicle engines and consequently also the thermal loads of the exhaust gas cooler, resulting in the known, caused by excessive thermal cycling cracks and the like damage that may have the failure of the system result.
  • the defined in the preamble of claim 1 heat exchanger goes out of the DE 32 42 619A1 out.
  • the grid-like support structure has there the task to direct the flow in the housing or influence.
  • elastic elements are provided on the support structure to compensate for certain tolerances in the housing and can, in which the tube bundle is inserted. Therefore, they consist of a suitable plastic, which is deformable over a wide range and therefore allows relatively large tolerance ranges.
  • the elastic elements are attached to the support structure made of metal. Although the vibration damping properties of the elastic members may be present, they are not effective enough. In addition, especially in heat exchangers of considerable length dimension, there are others Create vibrations that are inadequately controlled with the known elastic elements.
  • the object of the invention is to provide a heat exchanger which can contribute to the solution of the above-mentioned problems, in particular to reduce the vibration level.
  • the solution to this problem arises in a heat exchanger according to the preamble, according to the invention by the use of the characterizing features of claim 1 or claim 2 or claim 3 or ultimately of claim 7. Because a lattice-like metallic support structure is integrally formed with elastic cantilevers that point to the inside of the housing, which are deformed against the insertion direction of the bundle in the housing and whose spring force is directed against the housing to reduce the vibration level, and because a length changes permitting or compensating device is designed and provided with elastic properties, vibrations of the bundle in the housing are significantly reduced or damped.
  • the changes in length or changes in shape are induced by temperature changes that occur during operation of the heat exchanger.
  • the natural frequency of the bundle is raised.
  • the deformed elastic cantilevers protrude beyond its cross-sectional area before the bundle is inserted into the housing.
  • When inserting the elastic cantilevers are elastically deformed against their spring force to fit into the housing and then to deploy their spring force against the inside of the housing.
  • Alternative solutions suggest individual elastic, metallic cantilevers or springs, which are attached to a metallic support structure or between two metallic support structures. The inventors have come to the conclusion in the course of their investigations that it is insufficient to provide only such elastic, metallic cantilevers or springs or the like.
  • the housing consists of aluminum and is preferably designed as a casting into which the bundle designed as a stainless steel soldering construction can be inserted with tube sheets provided on the tube ends and a diffuser.
  • the housing has a connection flange which is matched to the diffuser, wherein the device permitting the length change has an elastic seal between the diffuser and the connection flange.
  • the block arrows in FIG. 1 indicate the flow through the exhaust gas heat exchanger, wherein the black block arrows should symbolize the exhaust gas and the block arrows without filling color symbolize the coolant, which is a cooling liquid.
  • the representation as double block arrows is intended to indicate that the media can flow through the exhaust gas heat exchanger either in countercurrent or in cocurrent.
  • There are corresponding inlets / outlets 70, 80 are provided.
  • the simple arrows in FIGS. 1 and 2 which point in the longitudinal direction of the heat exchanger, indicate the direction of insertion of the tube bundle into the housing 11 .
  • the tube bundle of the heat exchanger consists of a plurality of tubes 2, which are formed in the embodiment as drawn flat tubes 2 . Each flat tube 2 contains a turbulator 3.
  • the tube bundle in FIG. 1 has a plurality of (five) grid-like metallic holding devices 10, wherein (in the exemplary embodiment) only one of these was equipped in one piece with resilient cantilever arms 12 , which are arranged on opposite sides of the holding device 10 and the tube bundle.
  • a corresponding number of holding devices 10 may be integrally formed with resilient cantilever arms 12 .
  • springs 12b or the like may also be provided as individual parts which are to be force - and / or positively secured to the holding devices 10 .
  • FIGS. 3 and 4 two exemplary embodiments have been illustrated, which show resilient, metallic cantilever arms 12 as individual parts, which are fastened in a force-locking and form-fitting manner to a lattice-type metallic holding device 10 . From the figures, in particular from Fig. 2, it is further apparent that the resilient, metallic cantilever arms 12 are deformed against the insertion direction to facilitate insertion.
  • the position of the cantilever arms 12 was indicated in principle before insertion into the housing 11, not shown there on the example of a single cantilever 12 by dashed lines.
  • the cantilevers 12 are on arranged opposite sides.
  • the cantilevers 12 thus stand slightly farther from the imaginary center of the heat exchanger, and they are forced upon insertion of the tube bundle in the housing 11 , wherein they move toward the center resiliently, or undergo a change in shape lying in the elastic region.
  • the case constructed spring force of the cantilevers 12 then acts against the housing wall and ensures by interaction with the arranged on opposite sides cantilevers 12 for corresponding reduction of the vibrations that occur during operation of the heat exchanger, for example in a motor vehicle.
  • the lattice-like holding devices 10 may for example be in two parts, being pushed comb-like from opposite sides over the flat tubes 2 or they are in one piece and are then from one end of the tube bundle in the longitudinal direction to the slid position provided. In any case, the bars should extend transversely through the coolant channels 5 .
  • a tube plate 30 and a collection box or a diffuser 31 is attached.
  • the diffuser 31 changes the geometry on the exhaust side from a quadrangular shape on the tubesheet 30 into a round shape on the connection flange 60 (see below). All the components mentioned are made of stainless steel.
  • the construction described is connected in a brazing process to form a structural unit.
  • FIG. 8 shows an enlarged detail from FIG. 7.
  • a further flange 50 has been formed, to which the tube sheet 30 of the tube bundle and a further exhaust gas collection box 51 are attached.
  • fastening means 52 are formed on the housing 11 in order to fasten the exhaust gas heat exchanger to a connection structure, not shown.
  • connecting pieces 70 have also been provided on the housing 11 in order to allow the coolant to flow into or out of the coolant channels 5 of the tube bundle.
  • tensioning element (s) 40 which preferably replace the resilient metallic cantilevers 12 or springs or the like but could complement them
  • the tensioning element 40 may be a bolt that extends between the tubes 2 through the bundle and connects opposite housing walls. Rubber rings 41 or the like are inserted to dampen the vibrations.
  • Fig. 10 shows curved springs 12b or the like elements, which are fastened between two lattice-like metallic support structures 10 . The curvature is also carried out here so that the insertion process can be performed, wherein the springs 12b yield elastically. As shown in FIG.
  • the springs 12b arranged on opposite sides can also be arranged offset be, that is, not all four springs must lie in a passing through the tube bundle level. It has been found that by the proposed means the vibrations of the tube bundle in the housing are to be controlled so that fractures and / or noise developments caused thereby are avoided.
