Definitions

  • the invention relates to a heat exchanger, in particular a capacitor according to the preamble of claim 1 and a method for producing a heat exchanger according to the preamble of claim.
  • a heat exchanger which is preferably used as a condenser for motor vehicles.
  • the known condenser consists of a block formed by tubes and ribs and arranged on both sides of the block collecting pipes which receive the ends of the tubes.
  • the pipes are flowed through by refrigerant, which is supplied, deflected or discharged via the collecting pipes.
  • refrigerant which is supplied, deflected or discharged via the collecting pipes.
  • At the headers holders are attached, which the attachment of the capacitor in the vehicle or on an adjacent heat exchanger, for. B. serve a coolant radiator.
  • the condenser ie essentially the tubes, the fins, the headers and the holders are soldered in a single pass in a soldering oven, ie, connected to one another in a material-locking manner.
  • the positioning and fixing of the individual parts may be a problem, especially if no soldering devices are to be used.
  • the holders are therefore fixed in a suitable manner before the soldering process on the manifold, which is done by a positive connection between the holder and manifold.
  • the collecting tube has an opening for receiving a fixing piece attached to the holder.
  • a disadvantage of this solution is that the gap formed between the holder and collector in the region of the receiving opening must be soldered tight, which requires special care and brings with it the risk of leakage.
  • the holder is first fixed by pressure-fitting on the manifold and then integrally connected to the manifold, preferably soldered.
  • pressure joining results in a sufficient fixation of the holder on the manifold, so that it can be soldered without an additional soldering or other tools in the soldering oven.
  • pressure joining the wall of the manifold remains closed, there is only a deformation, wherein the simultaneously deformed surfaces of holder and manifold together enter into an intimate, sufficiently strong connection in the region of the pressure joint.
  • a further advantage is that a whopping system between holder and manifold is achieved, which ensures a perfect and firm soldering between holder and manifold.
  • the pressure joining is known per se, for. B. from the DE 43 25 421 A1 where a partition is connected to the inner wall of a manifold for positioning in the manifold.
  • the holder is designed as an extrusion part, which brings with it the advantage of lower production costs.
  • the holder may be formed as an angle profile, wherein a leg rests on the manifold and so to the contour, z. B. is adapted to a cylindrical shape of the manifold, that there is a sufficiently large contact area with a minimum and uniform Lotspalt.
  • the pressure joining is preferably carried out at two points, so-called pressure joints, which can be done with a conical or mandrel-shaped tool (stamp) on the opposite side, ie the inside of the manifold an anvil (tool) is provided so that a corresponding embossing contour for the collecting tube yields.
  • a conical or mandrel-shaped tool stamp
  • an anvil anvil
  • the object of the invention is also achieved by a method having the features of claim 9, wherein the holder is first positioned on the manifold and then fixed by pressure-joining.
  • the holder is first positioned on the manifold and then fixed by pressure-joining.
  • both parts caulked by means of female and male against each other, without the wall of the manifold is opened.
  • the holder is so fixed to the manifold - or on the cover of the manifold - it can be soldered to the manifold, without changing its position during the soldering process.
  • a soldering device for fixing the holder is thus superfluous.
  • the soldering of the holder with the manifold takes place simultaneously, d. H. in one operation with the soldering of the entire heat exchanger in the soldering oven.
  • Fig. 1 shows a part of a manifold 1 of a capacitor, not shown, known by the aforementioned WO 2004/065884 A1 whose disclosure content is fully incorporated in the present application.
  • the manifold 1 is formed in two parts, that is, it has a cover 2 and a bottom 3, which are set into each other and form a cylindrical hollow body.
  • the bottom 3 receives in unillustrated passages, also not shown tubes of the capacitor.
  • a holder 4 is arranged, which has an angle profile with a protruding from the lid legs 4a and one on the.
  • Lid resting leg 4b has.
  • the free leg 4a has a mounting opening 4c.
  • the leg 4b is fixed by means of two pressure joints 5, 6 on the lid 2, that is “stapled” so far that it does not dissolve during assembly and transport of the heat exchanger in a soldering furnace, not shown, from the header 1, respectively the cover 2.
  • Fig. 2 shows a section in the plane, corresponding to the line II-II in Fig. 2, ie a cross section through the cover 2 in the region of the pressure joint 6.
  • the pressure joining is - as mentioned - a known technology, which for example in the DE 43 25 421 A1 described and illustrated by another example. It is important first that the wall 2a of the lid 2 remains closed even after the Druckhegevorgang. Thus, the manifold 1 is absolutely tight in this area.
  • the leg 4b of the angle profile is adapted with its support surface of the approximately circular contour of the lid 2 and nestles against this contour.
  • the pressure joining is performed by tools, not shown, which consist on the one hand, ie on the outside of the manifold 1 from an approximately conical, pyramid or mandrel-shaped punch and on the other hand - on the inside of the lid - from an anvil to counter. You can also call both tools a patrix and die.
  • the punch male
  • the punch is moved in the direction of a center line 2b on the firmly held patrix.
  • the apparent from the drawing deformation of the material of the leg 4 b and the wall 2a is achieved.
  • After removing the tools angle profile 4 and cover 2 are fixed together and can be spent in a soldering furnace, not shown, and soldered there together with the entire capacitor.
  • All parts of the capacitor consist of Alurniniumwerkstoffen or aluminum alloys and are thus brazed hard.
