Definitions

  • the invention relates to a heat exchanger in caseless plate design, in each case two deformed plates form a flat tube, which are stacked, wherein at one end of the stack of flat tubes an entrance collection box in the manner of a diffuser and at the other end an outlet collection box, for example for exhaust or charge air is arranged, which flows through the flat tubes and is thereby cooled by means of coolant, which is introduced and diverted via extending into the stack into the channels, wherein the channels are formed by means of connected openings in the deformed plates and wherein the channels with between the flow tubes are hydraulically connected to the flat tubes.
  • exhaust heat exchangers in itself, including those that were proposed decades ago and used in heaters for cars of motor vehicles and come, bypassing the same with a bypass usually also required, among other things, because the heating demand is not permanently available. But even these exhaust heat exchangers usually belong to the tube bundle type or the spiral tube type. These include exhaust gas heat exchangers, such as the EP 942 156 A1 can be seen.
  • the object of the invention is to heat exchanger in caseless plate design such with a way to bypass, for example by means of exhaust or charge air form, that the exemplary functional properties and compactness are maintained, and that they remain mainly production-friendly.
  • a changeover valve is arranged, with which at least the majority of the recirculating exhaust gas flow is steered either by a plurality of cooled flat tubes of the stack or by at least one uncooled flat tube, wherein between the cooled and the at least one uncooled flat tube, an insulating plate is arranged, which is provided with a deformed plate the at least one uncooled flat tube and is connected to a deformed plate of a cooled flat tube.
  • the first independent task solution can be dispensed with the insulation plate by a changeover valve according to the invention is arranged in one of the manifolds, with at least the majority of the recirculating exhaust gas flow is steered either by a plurality of cooled flat tubes of the stack or by at least one uncooled flat tube, wherein a separation between the cooled flat tubes and the at least one uncooled flat tube is provided by the closure of the apertures forming the channels in at least one of the adjacent deformed plates.
  • Both proposed solutions also have a space not flowed through. This space is provided in the case with the insulating plate between this plate and an adjacent deformed plate, and in the case without the insulating plate, the space is preferably formed between two deformed plates.
  • the claims 1 and 2 should be understood to mean that an insulation panel according to claim 2 may be provided and in addition, the openings may be closed according to claim 1, for example, not be punched out.
  • the closure can also be made by inserting closure plates into the openings.
  • Each of the deformed plates is provided with a circumferential shape, as it is already in the EP 992 756 B1 has been shown and described, to which reference is expressly made, without having to repeat all the details here. It also refers to the EP with note no. 03 007 724.2, where certain features of the diffuser are shown and described.
  • Each two deformed plates are assembled into a flat tube and the flat tubes are assembled into a stack. In each case two deformed plates come together with their circumferential shape and include a space which constitutes a flow channel for a preferably liquid coolant. This construction is described in detail in the mentioned European patent.
  • the cooled and the uncooled flat tubes are assembled from the same deformed plates.
  • the possibility of forming the at least one uncooled flat tube from other deformed plates is still present.
  • the uncooled flat tube may have a larger cross section than a cooled flat tube.
  • the insulation plate has a projecting end over the stack, which cooperates with the switching valve, in particular with the flap of the switching valve.
  • the wall of the header, in which the change-over valve is located has two opposing openings in which the change-over valve can be mounted after brazing the heat exchanger. It is of particular advantage of the proposed solutions that the entire exhaust gas heat exchanger, for example, can still be connected or produced in a single soldering operation, in spite of the integrated switchover valve. The individual parts of the exhaust gas heat exchanger are held together by the over the ends of the flat tubes pushed collecting tanks. Elaborate welding operation, as required in heat exchangers of the prior art, are totally avoided. For further features, reference is made to the dependent claims.
  • it is an exhaust gas heat exchanger cooled by means of coolant of the internal combustion engine for a motor vehicle.
  • the exhaust gas heat exchanger is constructed in a housing-less plate construction.
  • the flat tubes 3 of the exhaust gas heat exchanger consist of deformed plates 1, 2 .
  • the deformed plates 1, 2 have a circumferential formation 80 .
  • two deformed plates 1, 2 form a flat tube 3, to which one of the plates 1 or 2 is rotated by 180 ° about its longitudinal axis and with the other plate to a flat tube 3 "edge 102 on edge 102" is assembled.
  • the flat tubes 3 are then stacked on each other, wherein the formation 80 comes to rest on the plate 1 or 2 of a flat tube 3 at the formation 80 of the plate 1 or 2 of the adjacent flat tube 3 . Only two cooled flat tubes 3 and only one uncooled flat tube 3 were shown in the exemplary embodiments.
  • a collecting box 4 is arranged in the manner of a diffuser.
  • a collecting box 5 is provided at the other end of a collecting box 5 , not shown. Both headers 4, 5 may be identical, except for the differences caused by the switching valve 20 , which are explained below.
  • the exhaust gas flows through the flat tubes 3 and is thereby cooled by means of the cooling liquid, which can be introduced and diverted via channels 10 extending into the stack.
  • the channels 10 are formed by means of connected openings 11 in the deformed plates 1, 2 .
  • passages 81 that can be produced by forming technology are arranged around each opening 11 in the exemplary embodiment.
  • the channels 10 which pass vertically through the heat exchanger.
  • a flow channel 12 wherein each of the flow channels 12 is hydraulically connected to the channels 10 .
  • Dashed arrows indicating the exhaust gas have been drawn, whereby the exhaust gas can either be introduced or discharged at the collection box 4 shown. Therefore, arrows were drawn with opposite flow direction.
  • a switching valve 20 is arranged, with which at least the majority of the recirculating exhaust gas flow is steered either by a plurality of cooled flat tubes 3 of the stack or by at least one uncooled flat tube 3 .
  • an insulation plate 30 is arranged between the cooled and the at least one uncooled flat tube 3 .
  • the substantially flat insulating plate 30 is connected on one side with a deformed plate 1 of the at least one uncooled flat tube 3 and on the other side with a deformed plate 2 of the adjacent cooled flat tube 3 .
  • the mentioned connection looks like that the insulation plate 30 abuts against the circumferential formation 80 of the two deformed plates 1, 2 and is connected thereto.
  • the circumferential formation 80 is approximately U - shaped in cross section, like the Fig. 3 and 4 best show.
  • the heat exchanger has a cover plate 60 and a base plate 70 , which are also deformed and have a slightly larger sheet thickness than the deformed heat exchanger plates 1 and 2, to provide additional stability. Further, the base plate 70 and the cover plate 60 have been assigned a holding function for the switching valve 20 and the actuator 21 of the switching valve 20 . For this purpose, the base plate 70 and the cover plate 60 have each provided with a projection 90. At the projections 90 , the changeover valve 20 and the actuator 21 are mounted by means of a holder 91 . ( Fig. 1 )
  • openings 15, 16 were provided in the wall 14 of the collecting tank 4 .
  • these openings 15, 16 are, as in the Fig. 1 shown bearing bushes 17, 18 used and fixed for a rotatable shaft 19 , at which the flap 22 of the switching valve 20 is located.
  • a cooperating with the flap 22 functional element 23 has been inserted into the collecting box 4 in order to support the action of the flap 22 .
  • the way of interaction is from the Fig. 5 to recognize. From the Fig.
  • the end 31 of the insulation plate 30 has been extended, this extended end 31 also cooperating with the flap 22 . It is advantageous not to form the flap 22 over a large area, because rattling noise or other functional disadvantages caused by the flow of the exhaust gas can occur.
  • the flap 22 can be made smaller by the cooperation with the end 31 of the insulating plate 30 and with the functional element 23 , as shown in FIG Fig. 5 you can see.
  • the already mentioned diffuser 4 also has in its wall 14 formations 103 (FIG. Fig. 1 ), which are intended to each have two edges 102 ( Fig. 4 ) at the end of the deformed plates 1, 2 of a flat tube 3 . Thereby, the entire stack of the flat tubes 3 is held together and the soldering in a single operation without additional auxiliary devices is made possible. Further details were given in the EP Application No. 03 007 724.2 described.
  • the Fig. 3 is a passing through both channels 10 for the cooling liquid cross section through an exhaust gas heat exchanger of the type which in the Fig. 1 is shown.
  • the Fig. 4 should only make clear the difference between the two solutions described.
  • the separation of the cooling liquid from the uncooled flat tube 3 was provided by providing the openings 11 in the deformed plate 1 and / or 2 with a closure 100 .
  • the closing can be done either by inserting an insert (not shown) into the corresponding passage 81 surrounding the opening 11 , or by not punching the openings 11 in this deformed plate 1 and / or 2 .
  • the in Fig. 4 shown variant can therefore be dispensed with the insulating plate 30 , although the same in the Fig. 4 is drawn.
  • the crossed-out reference numeral 30 is intended to indicate that the insulation plate 30 may be omitted, but not necessarily omitted, because the functionality remains with the insulation plate 30 .
  • the non-perfused space 101 is larger in this solution than in the first solution described above.
  • the Fig. 6 is a longitudinal section through a heat exchanger of the type according to Fig. 4 , That is, a heat exchanger in which the separation between the cooled and the uncooled flat tubes 3 has been realized by closure 100 of the openings 11 .
