Definitions

  • the invention relates to a heat exchanger, in particular a charge air cooler or coolant radiator for motor vehicles according to the preamble of claim 1.
  • Known heat exchangers especially for motor vehicles, often have a brazed block consisting of pipes, ribs and tube sheets, on which collecting boxes are placed from plastic.
  • the connection between the plastic boxes and the tubesheets is designed as a clamp or flare connection, wherein a seal is inserted between a flange of the plastic box and the tubesheet and clamped by the box / floor connection.
  • the plastic boxes are firmly and tightly connected to the metallic tube sheet.
  • Such a box / floor connection was by the DE-B 28 52 408 the Applicant known, wherein deformable edge regions of a tube sheet via a flange of a water box grip and thus produce a positive connection.
  • the plastic boxes tend at an increased internal pressure to deformations and increased stresses, in particular above the clamping area, which can also lead to leakage of the box / floor connection.
  • the plastic box has a U-shaped cross-sectional profile, which merges via a shoulder in the peripheral flange.
  • the stiffening ribs are arranged on the inside in the corner region of the approximately obtuse-angled shoulder, the inner edge of which is preferably aligned with the U-profile of the inner wall of the box.
  • the heat exchanger has a block with a single or multi-row flat tube system, wherein the ends of the flat tubes are received in passages of the tube sheet.
  • the stiffening ribs are spaced apart from one another which corresponds to the pipe pitch, i. the distance of the tubes, or an outer rib division, i. corresponds to the distance of ribs on the outside of the box.
  • the stiffening ribs can be arranged either at the level of the tubes or between them. This results in a uniform stiffening of the box longitudinal wall, which is adapted to the internal pressure load.
  • the transition region between the flange and the box wall in the longitudinal direction of the box is wave-shaped - as by the aforementioned DE-A 38 41 470 the applicant is already known.
  • the stiffening ribs are arranged in the region of this wave profile, either in the region of indentations (wave troughs) or bulges (wave crests) on the inside of the box.
  • the ribbed surfaces which protrude into the interior of the plastic box are arranged parallel to the Entformungscardi of the box.
  • the rib profiles can thus be incorporated into the core of the box, after the injection of the box in Entformungscardi and without the use of additional Sliders pulled, ie can be removed from the mold.
  • the advantage of lower manufacturing costs is achieved because no significant increase in the price of the pointed tool is carried out by the inventive design and arrangement of the stiffening ribs.
  • Fig. 1 shows a section of a heat exchanger 1 according to the invention, which has a tube sheet 2, a plastic box 3 and flat tubes 4, which are received in passages 2a of the tube sheet 2.
  • the tube sheet 2 has - as known from the prior art - an outer circumferential groove 2b, to which an outer edge region 2c connects.
  • the plastic box 3 has a not fully illustrated U-profile with a wall 3a, which merges into a flange 3b with greater wall thickness.
  • the flange 3b and a seal, not shown, are inserted into the channel 2b of the tube sheet 2 and clamped by the deformable edge portion 2c by a not shown crimping or clamping connection against the tube sheet 2.
  • Such box / floor connections are known from the above Technology, z. B. from the DE-A 38 41 470 known.
  • the flat tubes 4 are soldered to a block with not shown corrugated fins and the passages of the tube sheets, of which only the tube sheet 2 is partially visible.
  • On the soldered block are the plastic boxes, of which in turn only the box 3 is partially shown, put on and braced.
  • Fig. 2 shows a detail X from Fig. 1 ie, a transition region 5 between the wall 3a of the plastic box 3 and the flange 3b, wherein the transition 5 is formed as a shoulder and the inner edge 3d of the wall 3a is offset inwardly by about a wall thickness relative to the inner edge 3e of the flange 3b.
  • paragraph 5 receives the plastic box 3 so a so-called collection.
  • stiffening ribs 6 are arranged on the inside of the box, whose inner edges 6a are aligned with the inner edge of the box wall 3 a 3 a. The stiffening ribs 6 thus fill the obtuse angle of the shoulder 5 and extend into the region of the flange 3b.
  • the arrangement of the stiffening ribs 6, a stiffening of the box is achieved in the transition region 5, ie in a region which is subject to an increased load due to the internal pressure.
  • the heat exchanger 1 is preferably designed as a charge air cooler and therefore with compressed charge air of about 2 bar (with increasing pressures is expected in the future) acted on, which leads to a critical stress of the plastic box in the area above the flange - but the invention act Stiffening ribs against, without increasing the wall thickness, ie without a significant weight gain of the box.
  • Fig. 3 shows a perspective view of the corner region of a plastic box 7 with stiffening ribs 8 according to the invention on the inside of a longitudinal wall 7b.
  • the box 7 has a rectangular, circumferential flange 7a, not shown completely, above which a wavy formed transition region 9 is arranged, as he from the above-mentioned DE-A 38 41 470 the applicant is aware - the latter disclosure is therefore incorporated in full in the disclosure of this application.
  • the connection, not shown, between tube sheet and box 7 corresponds to the known design in this Offenlegungsschrift. Due to the wave-shaped design of the transition region 9, indentations 10 and bulges 11 result on the inside of the box 7.
  • the stiffening ribs 8 are arranged above the indentations 10 in this first embodiment.
  • Fig. 4 shows a second embodiment of the arrangement of stiffening ribs 12 in a plastic box 13, which also has a wavy transition region 9, corresponding to the previously described transition region 9 in Fig. 3 , Therefore, recesses 10 and bulges 11 are also formed on the inside of the box 13, which form the wave-shaped wall profile.
  • the stiffening ribs 12 are arranged here in the region of the bulges 11, ie on the raised areas of the box inner wall and in each case between two indentations 10. In this case, the length of the stiffening ribs 12 is greater than in the embodiment according to FIG Fig.
  • Fig. 5 shows a different view of the embodiment according to Fig. 3 ie, a view of a section of the longitudinal wall 7b of the plastic box 7 with flange 7a. Above the flange 7a of the wavy transition region 9 is indicated.
  • the longitudinal wall 7b is stiffened on its outer side by a transverse ribbing 7c.
  • Fig. 6 shows a section along the line VI-VI in Fig. 5 ie by the flange 7a.
  • On the inside of the longitudinal wall 7b are in the region of the wave profile 9 (see. Fig. 5 ) Indentations 10 and bulges 11, so wave peaks and wave troughs formed.
  • the stiffening ribs 8 extend up to a line 7d inwardly, which forms the inner contour of the longitudinal wall 7b. In this respect, the stiffening ribs 8 are aligned with the inner wall 7d, whereby a low pressure drop is ensured.
  • the distance between the stiffening ribs 10 otherwise corresponds to the distance of the flat tubes, not shown.
  • the ribs 8 also extend perpendicular to the plane of the drawing and are thus easily demountable with the main core of the box.
  • Fig. 7 shows a view of a section of the side wall 13a (see. Fig. 4 ) of the box 13 with wave profile 9.
  • Fig. 8 shows a section along the line VIII-VIII in Fig. 7 Through the flange of the box 13.
  • the vertically inwardly projecting stiffening ribs 12 extend to an edge 13b, which corresponds to the inner edge of the longitudinal wall 13a (perpendicular to the plane of the drawing).
  • the stiffening ribs 12 protrude no further than the longitudinal wall 13a itself in the interior of the box and thus also cause no increased pressure drop for the flow medium, eg. B. charge air or coolant.
