Definitions

  • the invention relates to a heat exchanger according to the preamble of claim 1.
  • Heat exchangers in particular heat exchangers such as gas coolers or condensers, which are used in the automotive sector, are essentially constructed of corrugated flat-tube blocks which terminate at respective opposite end portions in headers.
  • heat exchangers are manufactured by means of a cassetting process.
  • the corrugated finned flat tube block is stretched and pressed onto the manifolds.
  • vibrations, thermal expansions or residual stresses of the collecting tube in the brazing furnace can lead to a relative movement of the collecting tube relative to the flat tubes.
  • a heat exchanger for a motor vehicle which has a corrugated flat-tube block which is bounded on opposite sides by two side parts, which are also designed as flat tube profiles which are identical to the flat tube profiles of the corrugated flat-tube block, but not of one Heat transfer medium to be flowed through.
  • the heat exchanger is designed in all-metal construction, in which both the corrugated flat-tube block and provided on both end faces of the block tube plates are each made of light metal alloys.
  • Each tubesheet is provided on its opposite sides in the region of its directed away from the corrugated flat-tube block edge with two spaced, integrally formed bending tabs which are umbiegbar to secure the flat tube profiles on corrugated flat-tube block before soldering to the outside.
  • the bending tabs serving as mechanically acting fastening elements overlap the side parts in a form-fitting manner, as a result of which the side parts are position-secured on the corrugated ribbed flat-tube block and on the tubesheets.
  • the additional provision of a clamping frame for transport or storage of the corrugated flat-tube block including the side parts before soldering can thus be avoided.
  • a heat exchanger in particular a gas cooler for a motor vehicle, which has a block of tubular elements and rib elements, wherein the block is provided on at least one side surface with a side part, and pressed on at least one top and / or one bottom on a manifold is, which is respectively formed with a plurality of recesses for receiving the tubular elements.
  • the provided at least on one side surface of the block side part is caulked according to the invention with the at least one of the top or the bottom pressed-together manifold.
  • the tube elements are designed as flat tubes and the rib elements as corrugated ribs.
  • the tubular elements can be flowed through by a heating or cooling medium.
  • the side part is a pipe element which can not be flowed through by a heat or cooling medium, in particular a flat pipe. This is particularly cost effective, since no additional parts must be made.
  • the side part has at least one punctiform deformation, in particular a multiplicity of punctiform deformations.
  • the punctual deformations can be executed in any shape and number.
  • the side part is formed as a metal strip
  • the sheet metal strip may preferably be formed to I, U or L profile.
  • the side member is pushed through an outer recess of the plurality of recesses, so that an end portion of the side member is disposed in the header pipe.
  • the side part has at least a punctual deformation at the arranged in the collecting tube end portion, by the punctual deformation of the in the Collecting tube arranged end portion prevents the pipe elements from falling out of the manifold, for example during transport,
  • the side part has at least one further punctiform deformation on an outer section arranged outside the collecting tube. This advantageously prevents the tube elements from being pushed too deeply into the collecting tube.
  • the tubular elements are produced by means of an extrusion process.
  • the heat exchanger is manufactured by means of a Kassettier Kunststoffes.
  • each of the plurality of recesses is formed as a passage for a respective pipe member.
  • the collecting tube has two outer passages formed as passages for receiving in each case a side part, which may be formed as open passages.
  • the heat exchanger can be designed as a gas cooler or as a capacitor.
  • Fig. 1 is a schematic view of a portion of a heat exchanger 1 according to the prior art.
  • the heat exchanger 1 has a block 2, which consists of tubular elements 3 and rib elements 4, which are formed as flat tubes and corrugated ribs, which are arranged alternately.
  • the rib elements 4 of the block 2 are not completely shown in the figure and cover here only a part of the block 2 from.
  • the underside or, left side of the heat exchanger 1 is not shown in the figure; However, this is essentially like the top or right side of the heat exchanger 1 constructed.
  • the block 2 has an upper side 13 and a lower side (not shown).
  • the block 2 On its upper side 13 and, its underside, the block 2 is pressed onto a respective collecting tube 8, 8 ', wherein the tube ends of the individual tube elements 3 are pressed on opposite end faces into respective recesses 10, 10' of a collecting tube 5, which are designed as passages, and in the figure, as already mentioned above, only the right manifold 5 is shown
  • the upper or right manifold 5 has a Anslhlussstutzen 6 for a supply and return 7 of a cooling or dressing Jerusalemriuss (not shown).
  • the opposite narrow sides of the block 2 are each provided with a side part 8, 8 ', each at an upper end portion and a lower end portion (not shown) in an outer formed as a passage recess 10' of the plurality of as passages formed before soldering the parts of the heat roller bearing 1, the individual tube elements 3 in the embodiment of the prior art shown here only by the static friction of the tubular elements 3 and the side parts 8, 8 'in as Passages formed recesses 10, 10 'of the manifold 5, which can lead to problems during transport to the soldering furnaces, when the position of the tubular elements 3 changes with respect to the manifold 5 or even completely slip out of the manifold 5.
  • Fig. 2 shows a perspective view of an upper or right portion of a heat exchanger 1 according to the prior art, which is shown here without rib elements 4 and only with tubular elements 3.
  • the collecting tube 5 has a plurality of passages 10 formed as passages and on both sides each formed as an outer passage recess 10 ', of which only one is shown here. All formed as passages recesses 10, 10 'are of identical design and arranged at a uniform distance from each other on the manifold 5.
  • the side part 8 is inserted in the same manner as the pipe element 3 or, pressed, with as side part 8 here is a correspondingly shaped sheet metal strip.
  • the collecting tube 5 is - as already described above - before soldering - only held by the static friction of the individual tube elements 3 and the side parts 8, 8 'on this and can therefore easily solve or slip.
  • Fig. 3 is another perspective view of a portion of a heat exchanger 1 according to the prior art with a block 2 of alternately arranged tubular elements 3 and fin elements 4, wherein the tube elements 3 at their end portions (not shown) in the manifold 5 by respective recesses formed as passages 10th introduced are.
