Definitions
- Heat exchangers in particular intercoolers or coolant radiators for motor vehicles
- 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 Klemmoder flared connection, wherein between a flange of the plastic box and the tube sheet a seal is inserted and clamped by the box / floor connection. This means that the plastic crates are firmly and tightly connected to the metallic tubesheet.
- Such a box / floor connection was known from DE-B 28 52 408 of the Applicant, wherein deformable edge regions of a tube plate grip over a flange of a water box 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.
- DE-A 38 41 470 of the Applicant therefore a modified flange portion has been proposed for a so-called Wellenschlitzbördelung, wherein the wall of the box above the flange is wave-shaped and thus leads to a stiffening of the longitudinal wall.
- 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 already known from the aforementioned DE-A 38 41 470 of the applicant.
- 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 removal direction 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 detail of a heat exchanger according to the invention with connection between tube sheet and plastic box
- FIG. 2 shows a detail X from FIG. 1 with stiffening ribs according to the invention
- FIG. 3 shows a perspective view of the plastic box with a first arrangement of stiffening ribs
- FIG. 4 shows the plastic box with a second arrangement of stiffening ribs
- FIG. 5 shows a section of the longitudinal wall of the plastic box (first
- Fig. 6 is a section along the line Vl-Vl in Fig. 5
- Fig. 7 shows a section of the longitudinal wall of the plastic box (second
- Fig. 8 is a section along the line VIII-VIII in Fig. 7.
- Fig. 1 shows a section of a heat exchanger 1 according to the invention, which has a tube plate 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 boxes / floor connections are known from the cited state of Technology, z. B. from DE-A 38 41 470.
- 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 of Fig. 1, d. H. 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 by about a wall thickness relative to the inner edge 3e of the flange 3b inwardly.
- 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, d. H. in an area subject to an increased load due to the internal pressure.
- the heat exchanger 1 is preferably designed as a charge air cooler and is therefore charged with compressed charge air of about 2 bar (with increasing pressures is expected in the future), which leads to a critical stress of the plastic box in the area above the flange - the effect, however contrary to the stiffening ribs according to the invention, without increasing the wall thickness, d. H. even without a significant weight gain of the box 3.
- 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 not shown, circumferential flange 7a, above which a wave-shaped transition region 9 is arranged, as it is known from the aforementioned DE-A 38 41 470 of the Applicant - the latter disclosure is therefore fully in the disclosure of this application.
- the connection, not shown, between the tube bottom and the box 7 corresponds to the known design in these this disclosure. 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.
- stiffening ribs 12 in a plastic box 13, which likewise has a wave-shaped transitional area 9, corresponding to the previously described transition area 9 in FIG. 3. Therefore, on the inside of the box 13 are also recesses 10 and bulges 11 formed, which form the wave-shaped wall profile.
- the stiffening ribs 12 are arranged here in the region of the bulges 11, d. H. In this respect, the length of the stiffening ribs 12 is greater than in the embodiment of FIG. 3. In both embodiments, d. H.
- the stiffening ribs 8 and the stiffening ribs 11 whose rib surfaces (corresponding to the surface 6 in Fig.
- Fig. 5 shows another illustration of the embodiment of FIG. 3, d. H. 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 Vl-Vl in Fig. 5, ie through the flange 7a.
- indentations 10 and bulges 11 that is to say crests and wave troughs, are formed in the region of the wave profile 9 (see FIG.
- the stiffening ribs 8 projecting vertically into the interior are arranged, and indeed - as can be seen in FIG. 3 - above the indentations 10.
- the stiffening ribs 8 extend inwardly up to a line 7d, 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 (cf., FIG. 4) of the box 13 with wave profile 9.
- FIG. 7 shows a section along the line VIII-VIII in FIG. 7 through the flange of the box 13.
- the wave profile 9 results in indentations 10 and protrusions 11 on the inside on which the stiffening ribs 12 (see FIG. are arranged.
- 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.
