Definitions
- the invention relates to a rib for a heat exchanger according to claim 1 as well as one Method for the production of ribbed passages in such ribs according to claim 3.
- Such a rib is known from DE 34 23 746 A1.
- the Rib is provided with several passages, each one Having collared parallel to the passage axis collar. Each collar has in the upper area on opposite Pages each a right angles outward projecting, the Draft partially circumferential and thus flanking support edge on.
- the support edges serve as a support surface for positioning the corresponding adjacent rib.
- Such a method is known from CH 428 323.
- To Making the rib are in a flat ribbed sheet for each passage cuts introduced.
- the cut edges to a Collar set up, taking on opposite sides respectively a small, triangular flap parallel to the rib plane is turned off to the outside.
- Another rib and another method are from the DE 44 04 837 A1 known.
- a uniform rib division for the ribs of a rib / tube block of a heat exchanger to achieve are the tubes of the rib / tube block receiving Passage of the ribs with spacers in the form of on the circumference of the passages distributed pronounced noses educated.
- the object of the invention is a rib of the aforementioned To create a kind of good, with ease of manufacture and robust spacer functions to achieve a uniform rib division as the prior art allows.
- the object of the invention is also a method to create the rib passages to provide in the ribs
- each passage shows preferably two on opposite longitudinal sides of the By pulling arranged support edges, which are correspondingly opposite are turned off to the outside. The through the support edges formed flat bearing surface runs parallel to Ribs level.
- the at least one support edge with at least one coplanar protruding outward, ear-like Provided tab increases the flat bearing surface for each adjacent rib, so that a further improved blocking of the ribs / tube block is achievable.
- the separating cut to his opposite ends to form ear-like Curved tabs.
- the curved course of the separating cuts Ensures the formation of ear-like tabs, that at the subsequent forming stages no tearing of the ribbed plate at the level of the separating cut.
- an improved manufacturability of Rippen trimrat is achieved.
- Ribs 1, 1a as shown in Figs. 1 and 10 fragmentary are part of a rib / tube block for a Heat exchanger, especially for use in one Motor vehicle, wherein a plurality of parallel to each other aligned ribs 1, 1a each with a plurality of provided in parallel juxtaposed passages 3, 3a are a variety of parallel in a row next to each other take up running pipes.
- the pipes are shown at Embodiment designed as flat oval tubes, whereby the passages 3, 3a corresponding to identical are designed.
- the composite of ribs 1, 1a and pipes Ribs / tube block is mechanical in a conventional manner joined, wherein the passages 3, 3a of the superimposed Ribs 1, 1a each tightly enclose a tube.
- the passages 1, 1a of the ribs 3, 3a protrude respectively rectified from the associated rib and form for the overlying rib 1, 1a spacers, so that a achieved even rib pitch of the ribs / tube block becomes.
- the basic structure of a rib / tube block, such as he has been previously described, including the mechanical Fuegung of the ribs / tube block is detailed in the DE 44 04 837 A1 and disclosed by drawings, so that reference is made to this document for a more detailed explanation becomes.
- the rib 1 has, according to FIGS. 1, 4b and 5b, a flat ribbed plate 2, whose longitudinal edges each with one Rim groove 5 are provided. Along the flat ribbed plate 2 are aligned at regular intervals parallel to each other Passages 3 provided, the passage opening to the Outer contour of flat oval tubes is adapted. Between adjacent passages 3 are known gill fields 4, for further explanation also to the DE 44 04 837 A1 is referenced.
- the passages 3 are identical designed to each other.
- Each passage 3 has a circumferential, perpendicular to the rib plane defining Rippenblech 2 parked on one side collar 9, on in the area of the opposite longitudinal sides of the collar 9 connect two support edges 6 that are parked at right angles to the outside.
- the surface of the support edges 6 runs parallel to the rib plane formed by the ribbed sheet 2. in the Transition region between the collar 9 and the support edges. 6 are on both sides of the collar 9 three in even Interspersed noses 7 stamped.
- the Noses 7 are analogous to those described in DE 44 04 837 A1 Nasen so pyramideneckförmig designed that they in the Level of the support edges 6 a triangular cross-section form.
- the noses 7 are on the opposite longitudinal sides each passage 3 mirror-symmetrical to a central longitudinal plane each passage 3 arranged so that each longitudinal side the passage 3 and thus each support edge 6 respectively three lugs 7 are assigned.
- the noses 7 have next to one Spacer function, which in itself from DE 44 04 837 A1 is already known, for the two support edges 6 a stiffening function on, since they for the support edges 6 a forming web-like support function.
- the rib 1a of Fig. 10 substantially corresponds to the rib 1, as previously described. Same parts of the Rib 1a are therefore denoted by the same reference numerals, only with the addition of the letter a.
- the only Difference in the rib 1a to the rib 1 of FIG. 1 it is that the passages 3a of the rib 1a on diagonally opposite End portions of the opposite support edges 6a each have an ear-like tab 10 which is coplanar protrudes to the support edge 6a to the outside.
- the ear-like flap 10 has manufacturing causes, as described below will be.
- a separating cut 8 (FIGS. 2 a and 3 a) is introduced in the ribbed plate 2 at the level of the respective tube spacing and thus the subsequent positioning of the passages 3 transversely to the longitudinal axis of the ribbed plate 2, which is achieved by a suitable cutting tool is achieved with simultaneous support of the ribbed plate 2.
- the supporting edges 6 and the lugs 7 are created.
- a perpendicular to the ribbed plate effective punch S 1 is provided as a corresponding forming tool, which cooperates with a die, not shown.
- the die S 1 has a blade-like shape with a cross section which corresponds to the profile of the support edges 6 in FIG. 2 b.
- the embossing punch S 1 also has in each case laterally such embossing edges that the lugs 7 are embossed by the forming step together with the bending of the supporting edges 6.
- the supporting edges 6 protrude upward at right angles to the rib plane formed by the ribbed sheet 2.
- the reason of each triangular nose in cross-section 7 extends according to FIG. 3b at an acute angle to an underside of the ribbed plate 2 to the respective support edge 6 inwardly and upwardly.
- the cut edges formed by the separating cut 8 are thus exposed to the formation of the support edges 6 upwards and widened. The widening must be so gentle that no tearing of the separating cut 8 occurs at the opposite, end-side edge regions.
- a further widening of the passage opening takes place, whereby a circumferential collar 9, which in this process step is tilted obliquely upward and thus tapers conically upwards, is created by a further embossing punch S 2 which is enlarged in width relative to the embossing punch S 1 ,
- the embossing punch S 2 is provided with a correspondingly elliptical and tapered embossing contour.
- the collar 9 tapers towards the free end of the passage opening and the two support edges 6 protrude at right angles to the collar obliquely upwards and outwards.
- the final contour of the passage 3 is achieved by means of a further widened in cross-section punch S 3 , wherein the collar 9 is pulled through such that its peripheral wall is perpendicular to the rib plane turned up.
- This documented with reference to FIGS. 4b and 5b process step includes the completed passage, wherein the support edges 6 each project at right angles to the collar 9 to the outside.
- the method for producing the passages 3a from the ribbed sheet 2a of the rib 1a according to FIGS. 6 to 10 corresponds to FIG essentially the production method described above, so that only following the differences to the already described production process is received.
- the further completion of the ribs 1, 1a achieved by the gill panels 4, 4a and the edge grooves 5, 5a are impressed accordingly.
