Definitions

  • the invention relates to a heat exchanger, in particular for a motor vehicle according to the preamble of claim 1 - known by the EP 1 589 311 A1 the applicant.
  • the Applicant has disclosed a soldered condenser for an automotive air conditioner having a tube-fin block and two header tubes to which attachments, particularly holders or a refrigerant tube flange, are attached.
  • the holder has a fork-shaped or U-shaped profiled piece, which is adapted to the circumference of the manifold and this includes.
  • the manifold is formed in two pieces, ie it has a bottom part and a lid part, which are inserted into one another and soldered together. As a result, two offset longitudinal edges are formed, which serve as abutment surfaces for the correspondingly formed profile piece. For a positive fixation and positioning of the holder is achieved with respect to the manifold.
  • the applicant has disclosed a motor vehicle refrigerant condenser having a header to which a flange is fixed by means of a holder by a solder joint.
  • the manifold is in two pieces, ie formed with bottom and lid part and therefore has offset longitudinal edges.
  • the holder has a manufactured by extrusion C-shaped profile, which has on its inside paragraphs which are supported on the remote longitudinal edges of the manifold. This also fixation and positioning of the flange is achieved on the manifold.
  • a problem in the production of the known heat exchanger, in particular capacitors for automotive air conditioning systems consists in the attachment of the additional parts to the manifolds, which usually have a round or approximately circular cross-section due to the high internal pressure.
  • two-part headers arise - as described above - remote longitudinal edges on which the additional parts or holders are supported and thus can be prevented from twisting about the longitudinal axis (Z-axis) of the manifold.
  • manifolds with a closed round tube cross-section d. H. Collecting tubes, which are formed substantially in one piece, for.
  • B. longitudinally welded aluminum tubes which are also used for capacitors.
  • the condenser has a collecting tube formed in two parts, which is composed of an extruded cover part and a stamped and bent base part.
  • the extruded lid part has an integrally formed holder in the form of a continuous retaining strip and a flattened, continuous rib on the top.
  • the sole holder is formed integrally with the lid - disadvantageous here is that the entire lid of the manifold is made by extrusion.
  • a heat exchanger of the type mentioned in such a way that to be fastened to the manifold Additional parts against rotation relative to the manifold longitudinal axis are fixed and that a firm connection between manifold and attachment is achieved.
  • At least one driving surface is provided both at the periphery of the collecting tube and on the profile piece embracing the collecting tube, which brings about a positive connection between the two parts.
  • the driving surface is in principle designed such that it differs from the round peripheral shape, which favors a rotation of the additional part on the collecting tube, d. H. is formed inwardly or outwardly.
  • a form-fit triggering driving surface of the advantage is achieved that the additional part which is mounted on the manifold, can no longer rotate about the longitudinal axis of the manifold, but held due to the driving surfaces and simultaneously aligned in its position.
  • the secure fixation and clear alignment is important for the subsequent soldering process of the heat exchanger.
  • an increased strength of the connection between the additional part and manifold is achieved by the driving surface.
  • the driving surfaces are formed as a flattening or flattening of the manifold.
  • the profile piece of the additional part, which comprises the manifold has a corresponding flattening or flattening, which contacts the flattening of the manifold.
  • the manifold is preferably flattened only in the areas of the connection of additional part and manifold.
  • the additional part may be formed as a holder or as a flange, wherein these additional parts are preferably produced by extrusion. This will be the advantage of a simple Production, in particular the preferably flat driving surface achieved.
  • the invention is particularly useful for headers having a closed circular cross section, i. H. suitable for one-piece tubes.
  • the heat exchanger is designed as a condenser for a motor vehicle air conditioning system and is produced by soldering aluminum parts.
  • Fig. 1 shows a collecting pipe 1 for a flat-tube condenser, not shown, of an automotive air conditioning system.
  • the manifold 1 has a round cross-section and is flattened at two locations, ie it has two driving surfaces 2, 3 formed as flats.
  • Fig. 2 shows the manifold 1 in a view with a longitudinal axis Z, with a lying in the drawing below surface line 1a and a lying in the drawing above, interrupted by slot-shaped passages 4 generatrix 1b.
  • the flats 2, 3 are set back relative to the generatrix 1 a.
  • Fig. 3 shows a cross section through the enlarged collection tube 1, which has a closed cross-section, which in the overhead area in the drawing a passage 4 in the form of a slot-shaped opening having.
  • the manifold 1 is thus as a one-piece tube, z. B. formed as a welded aluminum tube.
  • the passages 4 are used to hold flat tubes not shown and are introduced by punching in the pipe.
  • the lying in the drawing below area of the manifold 1 has the flattening 2 (the flattening 3 according to Fig. 2 is preferably identical).
  • the collection tube 1 is comprised of a profile piece 5 of a holder 6, which is produced by extrusion.
  • the profile piece 5 has a U-profile, which consists of two approximately parallel U-legs 5a, 5b and arranged between the two U-legs 5a, 5b, formed substantially flat driving surface 5c.
  • the flattening 2 of the collecting tube 1 lies on the entire surface on the flat driving surface 5c.
  • the inner profile-as can be seen from the drawing-at least over a circumferential region of 180 ° on the circumference of the manifold 1 at.
  • a positive connection with respect to the longitudinal axis Z of the manifold 1 is made, ie the holder 6 is against the manifold 1 against rotation about the Z. Secured. Header 1 and profile piece 5 are connected together by soldering.
  • Fig. 4 shows the holder 6 with profile piece 5 in a perspective view.
  • the flat driving surface 5c is clearly visible between the two U-legs 5a, 5b.
  • the profile piece 5 and the entire holder 6 can be produced by extrusion from an aluminum extrusion alloy.
  • Fig. 5 shows the manifold 1 with two holders 6, 7, which as shown in FIG Fig. 3 connected to each other.
  • the assembly and production of the capacitor is preferably carried out as follows: first, an unillustrated block of flat tubes and ribs is cassetted. Subsequently, manifolds 1 are placed on the pipe ends, not shown, wherein the pipe ends are received by the passages 4.
  • the integrally manufactured headers which initially have a continuous round or circular cross-section, are provided for securing the holders 6, 7 Partially flattened, so that the above-mentioned driving surfaces 2, 3 arise. Then, the holders 6, 7 are placed and positioned, being accurately aligned due to the flats 2, 3 in their angular position with respect to the Z-axis.
  • the far-mounted capacitor is then placed in a soldering oven, not shown, and soldered there in one operation (in a "shot").
  • the invention is not limited to the embodiment shown in the drawing with flats 2, 3, which are flat. Rather, deviating from the plane driving surfaces, z. B. a stamped into the manifold concave surface or a pronounced from the contour of the manifold convex driving surface conceivable, d. H. Such surfaces, which form a positive connection between the additional part and manifold and thus prevent twisting of both parts about the Z-axis.
