Definitions

  • the invention relates to a brazed heat exchanger, in particular a brazed capacitor for a motor vehicle air conditioning system according to the preamble of claim 1 - known by the EP-A-0 584 993 , Similar heat exchangers are also off EP-A-1 046 876 and GB-A-2 285 858 known.
  • heat exchanger is a so-called flat tube condenser, which consists of flat tubes, arranged between these corrugated fins and two-piece manifolds with partitions. All parts that consist of an aluminum alloy are first mechanically joined and then soldered in a soldering oven. The partitions are used as separate items in the headers and positioned there.
  • the headers consist of a cup-shaped bottom, which receives the tubes, and a likewise cup-shaped lid, which has slots for receiving and positioning the partitions.
  • each partition forms with the cover to two (claim 1) or three places (claim 2) a joint connection: Due to the double joint connection according to claim 1 between the paragraphs of the partition and the cutouts in the lid, the partition is already adequately fixed - a so-called flag as in the prior art can be omitted.
  • the partition As known - on a flag which is inserted into a corresponding slot of the lid. The paragraphs of the partition fit into the marginal cutouts of the lid, so that a "three-point storage" is given for the partition after joining.
  • the partition can no longer tilt, but is exactly, ie aligned at an angle of 90 ° to the longitudinal axis.
  • the dimensions of the partition and the marginal cutouts in the lid are chosen so that the partition wall rests inside the lid, but not with their paragraphs in the cutouts.
  • the gap defined by tolerance is filled with solder material during the soldering process and thus leads to a dense soldering.
  • Fig. 1 shows a cross section through a manifold 1, whose cross-section is bounded by a cup-shaped, semi-cylindrical bottom 2 and a likewise cup-shaped, semi-cylindrical cover 3, which is designed in terms of its outer dimensions so that it can be inserted into the bottom 2.
  • the bottom 2 has two edge regions 4, 5 extending in the longitudinal direction of the tube (perpendicular to the plane of the drawing), which overlap with edge regions 6, 7 of the lid 3.
  • the cross section of the collecting tube 1 thus formed by the bottom 2 and the cover 3 is filled by a dividing wall 8 which, in its region facing the cover 3, has a lug 8a which penetrates a recess 3a (see Fig.
  • the partition wall 8 also has two paragraphs 8b, 8c in the region of the edges 6, 7 of the lid 3.
  • the bottom 2 receives in a manner not shown (eg in passages) flat tubes 9, which together with not shown corrugated fins form the network of a condenser for a motor vehicle air conditioning.
  • 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.
  • Fig. 3 and Fig. 3a show the cover 3 as a single part, on the one hand, the slot 3a for receiving the (not shown flags 8a) and on the other hand, the two sections 3b, 3c in the edges 6, 7 of the bottom 3 can be seen.
  • the cutouts 3b, 3c are U-shaped, ie, they are open towards the outside, and have two parallel side surfaces 13, 14 and a base 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 collection tube 1 is carried out as follows: first, the partitions 8 are inserted into the lid 3, and first introduced with their flag 8a in the slots 3a. After a short insertion path paragraphs 8b, 8c engage in the groove-shaped incisions 3b, 3c, ie the partition wall sections 8b, 8c slide like a feather key into a groove. The insertion movement of the partition 8 is completed when the abutment point A1 is reached inside the lid. In this position, there is still some air between paragraphs 8b, 8c and the base surface 15 of the cuts 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. Thereafter, the bottom 2 is pushed onto the lid 3 (or the lid 3 with the partition 8 inserted into the bottom 2). This insertion movement takes place until the partition wall 8 touches the stop point A2 in the interior of the lid 2. This ensures that the partition 8 has only one stop point, namely A2 with the bottom 2. It follows that the partition wall 8 can create both full against the inner wall of the lid 2 and against the inner wall of the bottom 3.
  • the partition 8 is also aligned by the above-mentioned three-point bearing perpendicular to the longitudinal axis, ie, the peripheral surface of the partition 8 is parallel to the inner wall of the lid 3 and bottom 2. These are the requirements for proper soldering.
  • the gap s between sections 8b, 8c and the base line 15 of the cuts 3b, 3c is filled during the soldering process with solder and is otherwise covered to the outside by the overlapping edge portions 4, 5 of the bottom, so that both outwardly and between the two adjacent chambers 10 and 11 is leaktight.
  • FIGS. 4 and 4a show a further embodiment of the invention with a modified partition wall shape in a representation analogous to FIGS. 2 and 2a.
  • Fig. 4 shows in a cross section a cover 20 of a manifold not fully shown.
  • the lid 20 has an approximately semi-oval cross-section and is bounded by edge regions 21, 22 upwards (in the drawing).
  • edge regions 21, 22 groove-like incisions 24, 25 are arranged in each case at the locations where a dividing wall is provided, which are illustrated by dashed lines in FIG. 4.
  • FIG. 4 a only the front incision 24 appears.
  • a partition wall 23 is inserted, which abuts with its lower half 23 a with its entire circumference on the inner surface of the lid 20.
  • the upper half 23b of the partition wall 23 has a larger diameter Db by twice the wall thickness d than the lower half 23a having 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 recesses 24, 25 and thus form a double joint between partition wall 23 and cover 20; This is sufficient for the positioning of the partition wall 23.
  • the partition wall 23 has no flag which is inserted through a slot in the lid. Rather, the lid 20 has a continuous, that is not interrupted by slots cross-section. This eliminates the insertion of the partition through the lid and the subsequent soldering, ie the risk of leakage is further reduced.
  • the assembly of the partition wall 23 takes place in such a way that it is inserted with its smaller half 23a in the lid 20a, so that the partition wall 23 with the lid 20 forms a common stop surface B1.
  • a gap s is left between the edge regions 21, 22 and the shoulders 23c, 23d.
  • the paragraphs 23c, 23d thus fit - like a key / groove connection - in the groove-like cutouts 24, 25 of the lid 20 a.
