Definitions

  • the invention relates to a heat exchanger, in particular for air conditioning systems, in particular of motor vehicles according to the preamble of claim 1 - known by the EP 1 439 367 A1 ,
  • the invention also relates to a method for producing a heat exchanger according to the preamble of claim 5.
  • a condenser consists essentially of a condenser block, which is constructed of flat tubes and corrugated fins, as well as arranged on both sides of the block manifolds, which are in communicating connection with the tubes of the condenser block.
  • the headers and the flat tubes of the condenser are flowed through by a refrigerant, which is supplied to the condenser from a refrigerant circuit via connecting flanges and withdrawn again.
  • the flanges are prefabricated separate parts, which are connected on the one hand with a header of the condenser and on the other hand with a refrigerant line.
  • the collar inserted into a bore of the connecting flange is plastically deformed by means of a polygonal punch such that a fixing takes place.
  • a polygonal punch Under Polygonstempel is a forming or expansion tool to understand, which has no circular cross-section, but a polygonal cross-section, which in Direction slightly tapered towards a point.
  • the polygonal punches may have three, four or six surfaces which are tapered in the shape of a pyramid or designed as a truncated pyramid. This tool deforms the collar in the connecting flange.
  • the prepared for the subsequent soldering, completed heat exchanger can be soldered due to the fixation of the invention without further Löt Anlagen in a brazing furnace, so that a Dichtlötung between the collar and the flange is achieved.
  • the inner cross section of the collar has a polygonal, preferably a hexagonal cross-section - like a hexagon socket.
  • the manifold is in two parts, d. H. formed with a lid and bottom part, wherein the collar is integrally formed on the lid.
  • the object of the invention is also achieved by a method having the features of claim 5.
  • the collar formed from the collecting tube is inserted into the bore of the connecting flange and then fixed by widening by means of the polygon punch. Connection flange and manifold cover are then sufficiently firmly connected together that then soldering can be done without further aids.
  • Fig. 1 shows a corner section of a condenser 1 for an unillustrated air conditioning system of a motor vehicle.
  • the condenser 1 has a condenser block 3 consisting of flat tubes 2 and ribs, not shown, which is connected to a collecting pipe 4.
  • Another manifold on the opposite side of the capacitor block is not shown.
  • the manifold 4 is formed in two parts, that is, it has a bottom 5 and a lid 6, which have an approximately semicircular cross section and are set in one another.
  • the end face of the collecting tube 4 is closed by an end wall 7 and forms a cavity which communicates with the flat tubes 2.
  • a collar 8 is integrally formed, ie by punching punching.
  • connection flange 9 is shown, which is to be connected to the manifold 4.
  • the connection flange 9 has a through-bore 10, which is connected on the one hand to a refrigerant connection line, not shown, and on the other hand to the collar 8 of the collecting tube 4.
  • the items shown in the drawing 2, 5, 6, 7, 8, 9 are made of aluminum or aluminum alloys and are soldered together. To prepare the soldering process, all parts are joined together, in particular, the connecting flange 9 is placed with its through hole 10 on the collar 8 of the manifold 4. This is already a preliminary positioning and centering of the connection flange 9 on the manifold 4th
  • Fig. 2 shows the flange 9, placed on the cover 6 of the manifold 4th
  • Fig. 3 shows a view in the direction X on the lid 6, wherein the flow cross section of the collar 8 appears as a blackened circular surface 8a.
  • the circular cross-section 8a is deformed by means of a polygon punch, not shown, ie widened in particular with respect to the through-bore 10 of the connecting flange 9.
  • the term "polygonal punch” is intended to mean a dome-shaped tool which has a non-circular, polygonal cross-section which tapers in the direction of impact, ie is wedge-shaped or has the shape of a truncated pyramid.
  • a deformation of the inner diameter of the collar 8 takes place substantially over the polygon edges, which dig into the material of the collar 8 and press it outward, whereby a pressure is created.
  • the cross section of the polygonal punch preferably has the shape of a regular hexagon, although more or fewer corners are possible.
