Definitions

  • the invention relates to a heat exchanger according to the preamble of claim 1 and a method according to the preamble of claim 3.
  • the invention has for its object to propose a heat exchanger of the generic type in which the pipe ends even with relatively large diameter ratios of e.g. 2.5: 1 to 8: 1 in the area of the heat exchanger network can be attached to the base plates in a liquid-tight and mechanically stable manner without additional solder, glue or the like.
  • the process for the production of such heat exchangers should be designed in such a way that the risk of damage to the pipes and / or guide plates and / or their collars is avoided.
  • the invention has the surprising advantage that good connections between the base plates and the pipe ends can be achieved by simply selecting the cross-sectional dimensions in the area of the pipes and pipe ends even if the pipes in the heat exchanger network originally had a comparatively large diameter ratio of 2.5: 1 to 8: 1 and the pipe ends have an oval shape even after attachment. With such diameter ratios, the bracing of the pipe ends in the sealing collar is sufficiently good, despite the oval cross-sectional shape retained, for practical purposes, in particular for series production. This makes it possible to connect single-row or multi-row heat exchanger networks with a high pipe density per unit area with a high diameter ratio to the associated base plates.
  • the method according to the invention there is above all the advantage that the pipe ends can be treated very gently during the fastening process, so that even when using large diameter ratios there is no danger of damaging the pipes or the guide plates connected to them.
  • the single-row heat exchanger shown in Fig. 1 is designed in the manner of a conventional tube cooler. It contains a number of plate-shaped baffles 1 arranged in parallel and at a distance, each of which has a series of oval openings which are arranged coaxially in the stacked state of the baffles 1.
  • the edges of the guide plates 1 delimiting the openings are extended by coaxial collars 30 (FIGS. 4, 5).
  • the openings and collars 30 are penetrated by tubes 3 arranged perpendicular to the guide plates 1 and having an oval cross section corresponding to the cross section of the openings and collars 30.
  • the upper and lower ends of the tubes 3 protrude through corresponding openings 5 each of a base plate 6 and 7 and are connected along their entire circumference with collars 8 (FIGS.
  • a conventional collecting box 9 is attached, which has a connection 10 for the supply or discharge of the medium flowing through the pipes 3, for example water.
  • a corresponding collecting box, not shown, is connected to the upper base plate 7.
  • the baffles 1 can still with usual Gill fields 31 (FIG. 6) for swirling the second medium, for example air, may be provided.
  • the tubes 3 preferably have a largest outside diameter a (FIG. 2), here briefly referred to as “large diameter”, which is 2.5 times to 8 times larger than the smallest outside diameter b , here briefly referred to as “small diameter” is so that their ratio is 2.5: 1 to 8: 1.
  • the tubes 3 can, as indicated in FIG. 3, also be arranged in two or more rows running parallel to the small diameter b .
  • the large diameter a is 12.4 mm and the small diameter b is 3.6 mm and the tubes have a wall thickness of 0.4 mm.
  • the tubes 3 are already firmly connected to the guide plates 1 and form a so-called heat exchanger network 11 (FIG. 1) with these. This connection is made as is generally known in particular in the manufacture of oil or water coolers for motor vehicles.
  • the base plate 7 is further provided with sealing elements 12 (FIGS. 4, 5) which have through openings 13 aligned with the openings 5 and sealing collars 14 attached to them.
  • the sealing elements 12, which can be connected to a one-piece or multi-piece sealing mat or plate extending over the width and length of the base plate 7, are arranged loosely and in such a way on one side of the base plate 7 that the sealing collar 14 from there into the Collar 8 of the base plate 7 protrude and lie firmly against it from the inside (FIGS. 4, 5).
  • the sealing elements 12 are sufficiently elastic for example, they are made from an elastomer.
  • a pressing tool 15 (FIG. 2) is preferably used, which consists of two plate-shaped pressing or molding jaws 15a, 15b, which run parallel to the axis 16 of the pressing tool 15 and have longitudinal edges 17a, 17b facing one another , which are preferably arranged straight and also parallel to the axis 16.
  • the clear distance of the shaped pockets 18a, b parallel to the axis 16 corresponds to the clear distance of the tubes 3 within a row.
  • the large diameter in the exemplary embodiment is 11.1 mm and the small diameter is 6.6 mm.
  • the thickness of the plate-shaped pressure jaws 15a, b is preferably approximately as large as the length of the sealing collar 14 in the axial direction thereof, plus a tube protrusion projecting beyond the sealing elements, which serves to compensate for the length and angularity tolerances of the tubes and base plates, and plus a transition area with the length l (Fig. 4), the smooth transition between the pre-pressed pipe end and the pipe sections unchanged in cross section in the network.
  • the pressure jaws 15a, b are placed according to FIGS. 2 and 3 from the top of the heat exchanger network 11 onto the ends of the tubes 3 protruding therefrom and then with mechanical, pneumatic, hydraulic or electrical means (not shown) in the direction of the arrows (FIG. 2) braced until their longitudinal edges 17a, b lie against each other, and then detached from each other in the opposite direction to the arrow.
  • the tube ends are deformed from the outside (Fig. 3) that their large diameter reduced to 11.1 mm and their small diameters increased to 6.6 mm and therefore the tube ends are given an outer contour corresponding to the inner contour of the recesses 19.
  • a line 20 indicates the cross-sectional shape of the pipe ends in the original state, since the remaining sections of the pipes 3 bordering on the deformed pipe ends and having the unchanged cross section are partially visible in the plan view.
  • heat exchanger networks are provided with a plurality of rows of tubes 3, as indicated schematically in FIG. 3, each row of tubes is treated accordingly, the individual rows preferably being treated in cycles with the same pressing tool 15.
  • the base plate 7 provided with the sealing elements 12 is now placed on the heat exchanger network 11 in the manner shown in FIG. 4, in which, on an exaggerated scale, a space allowing the insertion of the pipe ends into the sealing collar 14 is shown. In fact, this free space is only about one to two tenths of a millimeter, for example.
  • the base plate 7 is of course provided with one or more rows of openings 5 corresponding to the number of rows of pipes present.
  • the final attachment of the base plate 7 to the heat exchanger network 11 is carried out in that the tube ends are widened in a manner known per se by introducing a mandrel 21.
  • a number of mandrels 21 corresponding to the number of pipe ends is preferably provided, which are fastened to a common drive device via support elements 22.
  • the mandrel 21 has an oval outer cross section, which runs out via inclined surfaces 23 into a tip 24 that can be inserted into the pipe ends.
  • the outer cross section of the mandrel 21 is selected, for example, such that the tube ends are widened to a large diameter of 12 mm and a small diameter of 7.9 mm by inserting the mandrels 21 once on their outer circumference.
  • the elastic wall parts of the sealing collar 14 are expanded in the direction of their large diameters by 0.35 mm each and in the direction of their small diameters by 0.55 mm each, ie the pipe ends in them in the direction of the small diameters more tense.
  • this expansion of the pipe ends is preferably carried out in two steps, each step taking place in two stages.
  • a first expansion step the mandrels 21 according to FIG. 7 are used, the large and small diameters m and n of which are, for example, 0.6 mm smaller than the final, full inner diameters of the pipe ends.
  • mandrels 21 according to FIG. 7 are then also used, in which the diameters m and n correspond to the final dimensions of the pipe ends.
  • each step is also carried out in two stages in the sense that the tube ends in the insertion direction of the mandrels 21 first gradually over the large diameter and then gradually while maintaining the value achieved thereby over the small diameter, i.e. be expanded across the long sides.
  • This procedure has compared to a uniform and simultaneous expansion in all directions, e.g. the advantage that in the formation of the particularly crack-sensitive pipe sections having the small pipe radii, material from the adjacent pipe sections having the large pipe radii can flow into them, since the latter do not yet lie against the mandrel flanks at this point and therefore do not yet come into contact with static friction these are held.
  • the tips 24 of the mandrels 21 are also knife-like and are designed such that the tubes do not collapse in the transition regions from the widened tube ends to the intermediate tube sections and thereby reduce the tube cross sections in these regions.
  • This collapse of the tubes 3 could result from the thrust occurring in the longitudinal direction of the tubes 3 during the insertion of the mandrel.
  • the tip 24 is shaped so that its small diameter is slightly smaller than the small inner diameter of that within the heat exchanger network 11 located, middle pipe sections and their large diameter is slightly smaller than the large inner diameter of the pipe ends after pressing. This ensures that the long side walls of the tubes 3 only contact and support the tip 24 when they actually buckle inwards.
  • the tip 24 is followed by a mandrel section 25 which leads in the direction of insertion, which brings about the above-explained first expansion step in the direction of the large diameter to a preselected value and whose large diameter gradually increases from the tip to the diameter m and thereafter remains essentially constant until the other end of the mandrel.
  • the mandrel section 25 - viewed in the direction of insertion - is followed by a trailing mandrel section 26. This causes the second expansion step explained above in the direction of the small diameter to the preselected value. Its small diameter therefore has a value gradually increasing from the tip 25 to the diameter n , which then remains essentially constant up to the other end of the mandrel.
  • the dimension k is also used to denote the difference by which the full large diameter m - viewed in the direction of insertion of the mandrel 21 - is reached earlier than the full small diameter n when the pipe ends are widened.
  • the two mandrel sections 25, 26 can lie one behind the other in such a way that the widening in the direction of the small diameter only begins after the widening in the direction of the large diameter has been completed.
  • the ends of the tubes 3 and the base plate 7 are now permanently connected to one another in accordance with FIG. 6.
  • the heat exchanger network 11 which has been supplemented in this way can then be connected in a conventional manner to the lid of an associated collecting tank, the peripheral edge of which is inserted, for example, into a peripheral groove 27 provided with a sealant and which is then fastened to the base plate by bending clip clips.
  • vibration welding, gluing or the like are also possible for connection, in particular in the case of base plates and lids made of plastic.
  • a particular advantage of the external pressure is that the tubes 3 are deformed, but their scope remains essentially unchanged. Therefore, the forming process takes place without stretching the pipe walls and the resulting work hardening of the material layers involved, so that during the final expansion there is no danger that the pipe walls or collars will tear.
  • the expansion can take place in such a way that the sealing collar 14 is preloaded evenly radially in all directions, ie essentially radially to an imaginary central axis, but also with a preferred direction, for example parallel to the smallest diameters, if this is used to preload the individual case Sealing collar is appropriate.
  • Another significant advantage of the method according to the invention is that the large diameter of the tubes can be chosen larger than the large diameter of the tube ends after expansion. This makes it possible to produce compact, narrow heat exchangers in which the smallest distance between the walls of the tubes 3 in the heat exchanger network (dimension c in FIG. 6) in the direction of the large diameters is smaller than the corresponding distance between the insides of the sealing collars after they have been inserted into the Collar of the bottom plate is.
  • the method according to the invention is therefore particularly suitable for connecting heat exchanger networks to metal base plates, in which, in contrast to plastic base plates, this distance is limited for manufacturing reasons.
  • Another important advantage is that the expansion can be done without gradation and thus the pipe
  • the specified diameter ratios of the heat exchanger can be varied within wide limits. Diameter ratios of preferably 2.5: 1 to 5: 1, but also those of 5: 1 to 8: 1 for the tubes 3 of the heat exchanger network and from 1.2: 1 to 3: 1 at the tube ends in the fully assembled heat exchanger have been found proven to be particularly suitable. It would be because of the adaptation of the cross-sections of the pipe ends by deformation to a cross-section which essentially corresponds to the cross-section of the sealing collar It is also conceivable to carry out this deformation in a different way, for example from the inside, provided that this only results in a deformation with an essentially constant extent.
  • the invention is not limited to the use of base plates with the collars 8 on display. In particular when using plastic base plates, these collars 8 can be dispensed with entirely.
  • oval tube cross sections in the strictly mathematical sense.
  • oval is to be understood to mean all such cross-sectional shapes which are generally referred to as oval, elliptical, egg-shaped or the like or in the sense of "flat oval” in that they have two parallel, straight sides , the ends of which are connected to one another by oval, elliptical, semicircular or the like.
  • the pipe sections located between the machined ends should have a ratio of the large to the small diameter of 2.5: 1 to 8: 1.
