Definitions

  • the invention relates to a heat exchanger comprising wide and narrow sides, preferably two - part flat tubes, which are stacked on one another to form channels, in which, for example, a gas, such as exhaust gas or charge air, flows through the flat tubes and, by means of coolant, through the channels flows between the flat tubes, is cooled, wherein a partial housing is formed with a first and a second side and a connecting side, in which the stack of flat tubes is arranged.
  • a gas such as exhaust gas or charge air
  • a heat exchanger has been disclosed in the recently filed and not yet published European patent application with the application number EP 04 019 339.3 described. It is specifically about an exhaust gas heat exchanger, which should have a bypass.
  • the preamble of the present application is determined by the EP application with application number 04026647.0 , which is also not pre-published.
  • a heat exchanger is described with a part - housing.
  • the flat tubes in most cases consist of welded or drawn tubes. Mainly, when the flat tubes, as shown there, for example in Fig. 20, are composed of two parts, the local heat exchanger is disadvantageous because the accessibility to the connecting seams for the purpose of preparing the necessary soldering, for example, for the application of solder materials , is not given sufficiently.
  • the object of the present invention is to further improve the manufacturability of the heat exchanger having the features of the preamble.
  • the solution according to the invention is carried out in such a heat exchanger both with the characterizing features of patent claim 1 and with the characterizing features of claim 3.
  • the sub-housing is in the case of claim 1 formed as an open profile with a first and a second side and with a connecting side, which comprises only a part of the circumference of the stack of flat tubes, wherein the encompassed part about three sides of the circumference at least but more than 50% to about 90% of the total.
  • connecting the first page and the second page Side of the sub-housing at least one section is present, whereby the existing two-piece and stacked flat tubes to prepare for the soldering process are largely accessible.
  • connecting side is also the inlet and outlet for the coolant flowing in the channels.
  • connecting strips remain between the first and the second side (s) in which the inlet and outlet are arranged.
  • the flat tubes are kept at a distance to form the channels.
  • the channels are closed to the outside.
  • the flat tubes have a cross-sectional widening or a raised border.
  • the design has been further simplified because such a part-housing is much easier to produce, because it can, roughly speaking, be regarded as a sheet with two parallel folds.
  • the flat tubes can be much easier to insert or assemble in such a part-housing.
  • the weight of the heat exchanger is further reduced by the at least one cutout in the connecting side of the partial housing.
  • a bypass may or may not be provided in the part of the circumference of the stack of flat tubes not enclosed by the housing.
  • the first and the second side or the legs preferably extend in the direction of the broad sides of the flat tubes and are connected to the broad sides of the outer flat tubes of the stack. In a non-preferred application, the legs extend in the direction of the narrow sides of the flat tubes, in which case the connection is made on the narrow side of a flat tube.
  • the flat tubes have a cross-sectional enlargement extending in the longitudinal direction thereof or a raised border on which the legs are preferably connected to the broad sides of the flat tubes.
  • the cross-sectional widening can be provided in one or preferably in both broad sides of the flat tubes. It extends like a strip over the entire length of the flat tubes.
  • the legs or the first and the second side of the sub-housing have a connecting edge, which is preferably formed offset, and preferably takes over the connection with the cross-sectional widening. Between The housing and the broad side of the outer flat tube thus also a channel for the coolant has been formed. All flat tubes are preferably formed in two pieces and arranged one above the other, leaving gaps forming the channels, wherein the channels or the intermediate spaces are formed by the flat tubes preferably abutting each other with their cross-sectional widening or with their raised border.
  • the cross-sectional widening is a raised border of the circumference of the parts of the flat tubes. The raised border is interrupted at two points, namely where the entry or exit to / from the channels / s is provided.
  • connection strips of the housing in which corresponding inlet nozzle or outlet nozzle are arranged, which therefore therefore correspond to the interruptions in the raised borders in order to secure the operation.
  • the raised border is used in each case the connection of two flat tubes, preferably by soldering. Since the adjoining raised borders are wide enough and even, first-class solder joints are to be expected.
  • the preferably two-piece flat tubes may consist of two identical or of two differently shaped plates, wherein the channels are formed by the deformation of the plates.
  • the inlet header box and preferably also a separate outlet header box for the gas.
  • the collecting boxes are equipped with receiving beads for the corresponding section of the connecting edge of the flat tubes.
  • the flat tubes can have an inner insert.
  • the inner liner is a corrugated sheet whose corrugations preferably form discrete flow passages for the gas. It is intended to give the heat exchanger formed by the flat tubes, seen in the flow direction of the gas, straight or a curved shape. Also from the curved shape, the invention draws on their peculiarity over the prior art known to the Applicant.
  • the proposed part housing is for heat exchangers with a curved shape rather easy to produce, at least even easier than the above-mentioned prior art, in which the entire connecting side would have to be equipped with a curved contour.
  • FIGS. 1-5 relate to the first embodiment, in which the connection strips 20 are formed integrally with the first 12 and second side 13 . This can be seen particularly clearly in FIG. 1. There are two connecting strips 20 are provided.
  • one connecting strip 20 is the inlet 50 and in the other of the outlet 60 , preferably for the cooling liquid of a motor vehicle engine, not shown. Between the two connecting strips 20, which at the same time, as can be seen, represent the connecting side 15 , there is a large central cutout 16. Since the connecting strips 20 are not quite at the front or rear end, it can be said that left and right of the two connecting strips 20 also a respective cutout 16 is provided. 1, 2 and 3 show heat exchangers in which the exhaust gas or the charge air flows through the flat tubes 3 U-shaped, which by the dashed arrows pointing in opposite directions, on the left side in Fig. 3 and on the right Side of Fig. 2 were drawn, it can be seen. In FIG.
  • the heat exchanger according to FIG. 3 differs from the embodiment according to FIGS. 1 and 4 further in that in FIG. 3 the upper flat tube parts 3.1 are drawn cup-like, while the lower parts 3.2 are comparatively flat. Both parts 3.1 and 3.2 are not identical. In FIG. 4, the parts 3.1 and 3.2 are identical, wherein the connecting edge 2 of the two parts thus extends approximately at half the height of the flat tubes 3 , as well as Fig. 5 shows.
  • FIGS. 6-15 show an exemplary embodiment according to the alternative proposal, which differs above all from the embodiment of the first proposal already described above in that the connection strips 20 are manufactured there as individual parts and are joined between the first and second sides 12, 13 become.
  • This embodiment has the advantage that heat exchangers with a curved design, as shown in FIGS. 6-9, can be represented or produced more simply. Such and other irregular shapes, heat exchangers are often advantageous because they can contribute to the compact arrangement in the engine compartment of motor vehicles.
  • the embodiment has the further advantage that heat exchangers whose inlet 50 and outlet 60 are located on opposite sides of the heat exchangers, as can be seen in FIG. 7, can be manufactured more easily.
  • Fig. 7 shows otherwise a heat exchanger with a meandered contour. In Figs.
  • FIG. 6 differs from FIGS. 8 and 9 in that in FIG. 6 the connection strips 20 with inlet 50 and outlet 60, respectively, are arranged on the side facing inward, and in FIG. 8 on the side facing outward Page. Since these heat exchangers have a part-circle-like contour, "inward” in this context means pointing to an imaginary circle center point and pointing "outwards" from the imaginary circle center point.
  • the flat tubes 3 are composed of two flat tube parts 3.1 and 3.2 .
  • the flat tube parts 3.1, 3.2 have a raised border 30, which can be seen for example in FIG. 1, which allows a view of the overhead flat tube part 3.1 .
  • the raised border 30 is interrupted at two points. The corresponding locations have been designated by reference numeral 40 in Fig. 1, and may simply be referred to as interruption 40 of the grandeur of the border. (see also Fig. 13)
  • the two parts 3.1 and 3.2 are assembled to form a flat tube 3 , wherein the two parts are 3.1, 3.2 with their connecting edges 2 to each other, which are bent in the embodiment facing outward.
  • tabs 23 FIGS.
  • the connecting edges 2 which can be bent so that the parts 3.1 and 3.2 remain stable in their position relative to each other and thus later excellent solder joints can arise.
  • the flat tubes 3 thus formed are then stacked, wherein the flat tubes 3 come to rest with their raised edges 30 to each other to each form a channel 10 in the space between two flat tubes 3 . From the figures it can be seen that the height of the sublimity of the border 30 in the exemplary embodiments shown corresponds to approximately half the height of the channel 10 thus formed. In this case, the above-mentioned interruptions 40 are superimposed on one another and, in the region of the interruptions 40, make possible the hydraulic connection to the channels 10.
  • a raised edge 30 is provided only on one of the two each forming a channel flat tubes, or on one of the two flat tube parts forming a flat tube. In such cases, then the height of the grandeur is equal to the height of the channel 10th
  • the mentioned hydraulic connection is now provided by the specially designed connecting strips 20 , which are formed with a corresponding inlet 50 and outlet 60 , respectively.
  • the connecting strips 20 are similar per se in both embodiments, there are differences in the production because, as already mentioned, in the first described embodiment, the connecting strips 20 are formed integrally with the first and second sides 12, 13 and in the second Embodiment, the connecting strips 20 as individual parts between the first and second sides 12, 13 are attached.
  • the mentioned production takes place by means of forming machines and corresponding tools (not shown).
  • the connecting strips 20 are provided with beads 21 to comprise the outwardly projecting connecting edges 2 to be able to, each bead 21 each receives two projecting connecting edges 2 of a flat tube 3 in itself.
  • the connecting strips 20 can be formed with lugs 22 , which in each case, where two flat tubes 3 abut each other with their raised border 30 , to lead in the resulting bending radius range there to perfect, ie to dense and durable solder joints. (See FIGS. 5 and / or 12). It must also be emphasized in FIG.
  • connecting strips 20 also connect the first and second sides 12, 13 physically, which is to be regarded as preferred, because the connecting strips 20 are there after the type of clip the preassembled items of the heat exchanger together to make it easier to prepare the heat exchanger for soldering.
  • this training is not necessarily required because the cohesion of the items is created, for example, by the stack enclosing manifolds 5, 6 .
  • ends of the connecting strips 20 just before the edge of the first and second sides 12, 13 and are thus physically connected only to the flat tubes 3 and the flat tube parts 3.1, 3.2.
  • Connecting strips 20 in the sense of the proposed alternative are thus those which are connected either directly or indirectly to the first and the second side 12, 13 . Accordingly, according to the will of this alternative teaching, a sub-housing is to be considered even if it consists of individual parts 12, 13, 20 which are connected either directly or indirectly.
  • the parts 3.1 and 3.2 of the flat tubes 3 were shown with reference to the second embodiment.
  • the parts 3.1 and 3.2 were provided with formations 33 .
  • Such or other formations may also be present in the first embodiment.
  • the formations 33 can also be replaced by means of known inner inserts in order to effect the intended increased durability and turbulence formation in the exhaust gas or in the charge air.
  • the flat tubes 3 were formed with two separate passages 70 , wherein the separation was made by means of a dividing web 35 inserted into the flat tubes 3 , but which, as already mentioned above, by means of continuous formations 33 is also possible.
  • FIG. 11 represents the longitudinal section E - E in the region of an inlet 50 or outlet 60 for charge air or exhaust gas.
  • the flat tube parts 3.1 and 3.2 are in this area, which is the end face of the parts 3.1, 3.2 , provided with a deformation 31 , which is intended to optimize the performance of the flow of the incoming charge air or the exhaust gas.
  • the deformation 31 immediately adjoins the raised border 30 and protrudes into the inlet 50 a little.
