Definitions

  • the invention relates to an exhaust gas heat exchanger with pairs of bowl-shaped Heat exchanger plates; forms each pair of bowl-shaped heat exchanger plates a flow channel for cooling water by using the peripheral flange are mirrored assembled and connected so that the edge flange of the a heat exchanger plate on one side and the edge flange on the other Heat exchanger plate is directed to the opposite side, as well as with openings in the heat exchanger plates, which lie on a common line to form the collecting and distribution channel for the cooling water and with between the above-mentioned flow channels arranged further flow channels for the exhaust gas.
  • This exhaust gas heat exchanger is known from EP 677 715.
  • the known exhaust gas heat exchanger can be regarded as disadvantageous because breakthroughs on the exhaust side caused by corrosion lead to the mixing of the exhaust gas with the cooling water. Since the exhaust gases contain very aggressive substances, the possibility of rusting through is not far away. Therefore, the heat exchanger plates, the corrugated fins and the connecting pieces are made of stainless steel in the document mentioned, but this increases the costs. In addition, despite this measure, there is no guarantee that mixing will not happen, since even the stainless steel plates, if they are not the highest quality, can be attacked, at least in the vicinity of the soldered connections. Especially since there is a constant effort to reduce the sheet thickness of the heat exchanger plates.
  • the required housing which surrounds the heat exchanger.
  • the exhaust gas heat exchanger is constructed in the so-called document in a so-called rod-plate construction and has an outer housing. This otherwise advantageous construction has the disadvantage that the number of individual parts and the number and length of the soldered connections are quite large, which increases the risk that soldering errors can occur.
  • the object of the invention is to further reduce the manufacturing costs in the exhaust gas heat exchanger specified in the preamble and also to ensure greater security against mixing of the exhaust gas with the cooling water, with at the same time low pressure loss on the exhaust side.
  • the solution according to the invention results from the characterizing part of patent claim 1.
  • the problem is solved by the skillful combination of features which may be known individually in heat exchanger construction, the inventors having recognized that their novel interaction leads to an inventive exhaust gas heat exchanger in which the exhaust gas is cooled with liquid.
  • the exhaust gas heat exchanger is designed in a housingless design, that the flow channels formed from shell-shaped heat exchanger plates are provided for the cooling water and that the flow channels for the exhaust gas arranged therebetween are approximately straight flat tubes which open at opposite ends in tube sheets to which the Exhaust pipe is connected.
  • the tube sheets have a diameter that is at least partially larger than the subsequent cross-sectional dimension of the heat exchanger.
  • the tube sheets are preferably circular parts, as a result of which the production and connection of the likewise round exhaust pipe can be carried out more easily.
  • the flue gas pipe can be connected to the heat exchanger using screws, clamps or clamping rings.
  • At least one type of flow channel has a corrugated or similarly structured surface. The corrugated surface structure sufficiently ensures that, in the event of rusting, the exhaust gas can escape to the atmosphere and not easily get into the cooling water.
  • the pressure loss on the exhaust side is extremely low because the associated flow channels have no deflections and because the tube sheets are kept so large that this requirement can be met. Furthermore, the distributor and the collecting space for the cooling water are arranged in projecting areas of the bowl-shaped heat exchanger plates, which are outside the cross section of the flat tubes. This also makes a contribution to reducing the pressure loss on the exhaust side, because the distributor and collection space are therefore not in the flow area of the exhaust gases and do not impede their flow.
  • the manufacturing costs are reduced in that the water-cooled exhaust gas heat exchanger according to the invention only has to be made of stainless steel on the exhaust side - that is, the flat tubes and the tube sheets - while all other parts can be made of aluminum.
  • the water-cooled exhaust gas heat exchanger from EP 677 715 is made entirely of stainless steel.
  • the proposed exhaust gas heat exchanger therefore also has a lower weight. Furthermore, a contribution to lowering the manufacturing costs can be seen in the fact that the water-cooled exhaust gas heat exchanger, as stated above, is provided in a housing-free design.
  • the external flow channels are cooling water channels, so that the radiant heat of the heat exchanger is reduced, which is not insignificant in exhaust gas heat exchangers because of the high exhaust gas temperatures.
  • the bowl-shaped heat exchanger plates, which form the flow channels for the cooling water have inward corrugated support knobs in their corrugated surface, which are soldered at their apex to the same support knobs of the adjacent heat exchanger plate.
  • the flat tubes that carry the exhaust gas can either be drawn tubes or flat tubes welded with a longitudinal seam, or they can be formed from two half-shells that are soldered together on the peripheral edge flange. Punched or rolled inner inserts can be arranged in the flat tubes, which are soldered to the tubes in order to promote heat exchange and to increase the stability.
  • the wall of the flat tubes has a wave-like structure.
  • the wave peaks and valleys run in the longitudinal direction of the flat tubes.
  • there are projecting and angled sections on their edge flange which interlock and serve to correctly position two half-shells to form a flat tube. These sections are comparable to those on the edge flange of the heat exchanger plates. Openings are punched out in the tube sheets, which are adapted to the cross section of the flat tubes and which have passages which are either directed towards the exhaust gas line or towards the interior of the heat exchanger.
  • FIG. 5 shows the view from the direction of the clamping ring 26 of the embodiment from FIGS. 1, 2 and 4.
  • inner inserts 24 in the flat tubes 8 have been completely dispensed with.
  • the walls of the flat tubes 8 consisting of two half-shells 8/1 and 8/2 were formed with a distinct wave-like structure 22.
  • the wave crests and the wave troughs here run in the longitudinal direction of the flat tubes 8 or the flow channels 14.
  • the heat exchanger plates 6 are preferably also included formed a smooth surface, apart from the embossed knobs 11.
  • This embodiment is particularly suitable for exhaust gas heat exchangers because the risk of clogging of the flat tubes 8 by deposits is significantly lower.
  • FIG. 7 shows the view belonging to the exemplary embodiment in FIG. 6 from the direction of the clamping ring 26.
  • the longitudinal wave-like structure 22 of the flow channels 14 is also evident from this illustration.
  • the longitudinal section in FIG. 8 also belonging to this embodiment shows that the undulating structure 22 ends in front of the tube sheet 13.
  • the passages 25 on the tube plate 13 were made towards the heat exchanger and the flat tubes 8 were plugged with their ends onto these passages 25
  • FIG. 8 shows another connection to the exhaust pipe, not shown.
  • FIG. 9 can be interpreted as a cross section in FIG. 3. It differs from FIG. 4 in that welded or drawn flat tubes 8 have been used here. Furthermore, the attachment was selected with the aid of a connecting flange 27, as is also shown in FIG. 3. 10 differs from the exemplary embodiment in FIG. 9 in that in FIG. 10 the passages 25 on the tube sheet 13 are directed towards the exhaust gas line, while in FIG. 9 the passages 25 point towards the heat exchanger.
  • FIG. 11 shows an exemplary embodiment in which the overhanging regions 7, in which the collecting and distribution spaces 20, 21 are arranged, are located on opposite sides of the heat exchanger. Therefore, two different types of heat exchanger plates 6 must be used here.
  • Fig. 12 shows a partial longitudinal section, similar to Fig. 8, but in which the heat exchanger plates 6 have a corrugated surface structure 22 in order to achieve greater security against mixing of exhaust gas and cooling water.
  • the flat tubes 8 have also been used in the passages 25 of the tube sheet 13.
