Definitions

  • the invention relates to a soldered heat exchanger, in particular a soldered condenser for a motor vehicle air conditioning system according to the preamble of claims 1 and 2 - known from DE-A 43 39 952.
  • the known heat exchanger is a so-called flat tube condenser, which consists of flat tubes, corrugated fins arranged between them and two-part header tubes with partitions. All parts, which consist of an aluminum alloy, are first mechanically joined and then soldered in a soldering furnace. The partitions are inserted as separate individual parts in the header pipes and positioned there.
  • the collecting pipes consist of a bowl-shaped bottom, which receives the pipes, and a likewise bowl-shaped cover, which has slots for receiving and positioning the partitions.
  • the cover of the collecting tube has cutouts in the region of the partition walls at its edges, into which the partition walls engage, ie each partition wall forms two with the cover (Claim 1) or three places (Claim 2) a joint connection: Due to the double joint connection according to claim 1 between the shoulders of the partition and the cutouts in the cover, the partition is already sufficiently fixed - a so-called flag as in the prior art can be omitted , In the secondary solution according to claim 2, the partition - as is known - has a flag which is inserted into a corresponding slot in the cover.
  • the heels of the partition insert into the peripheral cut-outs of the lid, so that a "three-point bearing" is given for the separation wall after joining is.
  • the partition wall may thus not tilt, but is exact, ie at an angle of 90 ° to the longitudinal axis
  • the dimensions of the partition and the cut-outs in the cover are selected so that the partition rests on the inside of the cover, but not with its shoulders in the cut-outs.
  • the bottom is placed over the cover with the pre-assembled Partitions are pushed as far as they will go to the partition walls and - as is known - secured with grain punches.
  • the inner surface of the floor then only bears against the partition at one point. Overall, this results in a statically determined system of cover, partition wall and floor, ie there are clear contact surfaces with minimal gaps, so that leak-free soldering can be achieved.
  • a certain amount of play is provided between the shoulders of the partition and the base of the cutouts on the edge. This ensures that there is only one contact surface between the partition on the one hand and the cover and base on the other.
  • the gap defined by tolerance is filled with solder material during the soldering process and thus leads to tight soldering.
  • FIG. 1a is a side view of Fig. 2,
  • Fig. 2 shows a cross section through the lid and the partition of the
  • FIG. 2a is a side view of FIG. 2,
  • Fig. 3a is a side view of Fig. 3 and
  • Fig. 1 shows a cross section through a manifold 1, the cross section of which is delimited by a shell-shaped, semi-cylindrical bottom 2 and a likewise shell-shaped, semi-cylindrical cover 3, which is designed with regard to its external dimension so that it can be inserted into the bottom 2.
  • the base 2 has two edge regions 4, 5 which run in the longitudinal direction of the tube (perpendicular to the plane of the drawing) and which overlap with edge regions 6, 7 of the cover 3.
  • the cross section of the collecting tube 1 thus formed by the base 2 and cover 3 is filled by a partition 8, which in its area facing the cover 3 has a flag 8a which penetrates a recess 3a (see FIG.
  • the partition 8 also has two shoulders 8b, 8c in the region of the edges 6, 7 of the cover 3.
  • the base 2 receives flat tubes 9 in a manner not shown in detail (e.g. in passages) which, together with corrugated fins (not shown), form the network of a condenser for a motor vehicle air conditioning system.
  • Fig. 2 and Fig. 2a show the manifold 1 without the lid 2, ie only with bottom 3 and partition 8, which has a width b.
  • the cutouts 3b, 3c are U-shaped, i. H. open to the outside, designed and have two parallel side surfaces 13, 14 and a base surface 15 running perpendicular to them.
  • the distance between the two side surfaces 13, 14 has the dimension b, which corresponds to the width b of the partition 8.
  • the assembly of the collecting tube 1 is carried out as follows: first, the partition walls 8 are inserted into the cover 3, first with their flag 8a inserted into the slots 3a. After a short insertion path, the shoulders 8b, 8c engage in the groove-shaped incisions 3b, 3c, ie the partition sections 8b, 8c slide into a groove like a feather key. The insertion movement of the partition 8 is ended when the stop A1 is reached inside the cover. In this position there is still some air between the shoulders 8b, 8c and the base 15 of the incisions 3b, 3c, ie a minimal gap s (cf. FIGS. 1a and 2). This ensures that the partition 8 is always moved to the stop A1.
  • the partition 8 Due to the tolerances between the partition 8, 8a and the slot 3a and the incisions 3c, 3b, the partition 8 is slightly clamped in this position, so that it is fixed.
  • the bottom 2 is then pushed onto the lid 3 (or the lid 3 with the partition 8 is pushed into the bottom 2). This insertion movement takes place until the partition 8 touches the stop A2 in the interior of the cover 2. This ensures that the partition 8 has only one stop, namely A2 with the bottom 2. It follows from this that the partition 8 can lie completely against the inner wall of the cover 2 and also against the inner wall of the bottom 3.
  • the partition 8 is also aligned perpendicular to the longitudinal axis by the three-point bearing mentioned above, ie the peripheral surface of the partition 8 runs parallel to the inner wall of the lid 3 and bottom 2. These are the prerequisites for perfect soldering.
  • the gap s existing between paragraphs 8b, 8c and the base line 15 of the incisions 3b, 3c is filled with solder during the soldering process and is otherwise covered to the outside by the overlapping edge regions 4, 5 of the base, so that there is a seal both to the outside and between the two adjacent chambers 10 and 11.
  • FIGS. 4 and 4a show a further embodiment of the invention with a modified partition shape in a representation analogous to FIGS. 2 and 2a.
  • Fig. 4 shows in a cross section a cover 20 of a manifold, not shown completely.
  • the cover 20 has an approximately semi-oval cross-section and is delimited at the top by edge regions 21, 22 (in the drawing).
  • edge regions 21, 22 in the drawing.
  • groove-like incisions 24, 25 are arranged at the points where a partition is provided, which are shown in broken lines in FIG. 4 - only the front incision 24 appears in FIG. 4a
  • Cover 20 is a partition 23 is used, which abuts with its entire circumference on the inner surface of the cover 20 with its lower half 23a.
  • the upper half 23b of the partition 23 has a diameter Db which is twice the wall thickness d than the lower half 23a with a diameter Da. Both cross-sectional halves 23a and 23b merge into one another via a shoulder 23c, 23d. The shoulders 23c, 23d engage in the incisions 24, 25 and thus form a double joint connection between the partition 23 and the cover 20; this is sufficient for positioning the partition 23.
  • the partition 23 has no flag that is inserted through a slot in the lid. Rather, the cover 20 has a continuous cross-section, that is to say that it is not interrupted by slots. This eliminates the need to push the partition through the cover and the subsequent soldering, ie the risk of leakage is further reduced.
  • the partition 23 is installed in such a way that its smaller half 23a is inserted into the cover 20a, so that the partition 23 forms a common stop surface B1 with the cover 20. So that there is definitely a stop or contact in the area B1, a gap s is left between the edge areas 21, 22 and the shoulders 23c, 23d. The shoulders 23c, 23d thus fit into the groove-like cutouts 24, 25 of the cover 20 like a feather key / groove connection.
  • a bottom (not shown here) is pushed over the cover 20 with the partition 23 inserted — analogous to the exemplary embodiment according to FIG. 1, so that a stop surface B2 is formed between the partition 23 and the bottom not shown.
