Definitions
- the invention relates to a metal support matrix for a catalytic reactor for exhaust gas purification, in particular for internal combustion engines, according to the preamble of patent claim 1.
- the aforementioned method has the disadvantage that special shapes are produced by inserting loose filler pieces Need to become. It is also disadvantageous that devouring thicker sheet stacks, which are required for producing larger catalyst diameters, requires extraordinarily high forces.
- the invention is therefore based on the object of designing a metal support matrix of the type mentioned at the outset in such a way that a homogeneous, easy-to-manufacture honeycomb body is formed from a multiplicity of sheet metal layers and, if possible, each sheet metal layer comes into contact with the enveloping jacket.
- the proposed design allows the simple production of a metal support matrix from a large number of sheet metal layers.
- the adaptation to different shapes of the jacket is easily possible.
- a variety of shapes can be created by varying the length and / or the thickness of the individual stacks will.
- special shapes for example elliptical carrier matrices, it is not necessary to insert filler pieces, as a result of which a substantial reduction in production costs is achieved.
- Catalyst forms with larger diameters can advantageously be designed in such a way that the metal support matrix consists of a larger number of stacks. This reduces the thickness of the individual stacks, the individual sheet layers are evenly distributed in the metal support matrix, and the forces required for the stacks to be devoured are reduced.
- the configuration of the metal carrier matrix from four stacks is also particularly advantageous, since this configuration results in a very uniform distribution of the lines of contact of the sheet metal layers with the jacket on the inner jacket surface.
- the embodiment according to claim 5 enables the advantageous embodiment of an elliptical or ellipse-like catalyst shape.
- the even distribution of the lines of contact on the inner circumferential surface in elliptical or elliptical-like catalyst shapes can be expediently obtained by pressing a round metal support matrix, which has a larger cavity inside, to the desired elliptical or elliptical-like shape.
- the shape of the stack from which the metal carrier matrix is made always has two parallel edges in the side view.
- the ends of the stack can run out at different angles, so that the geometric shapes described in the characterizing part of claim 1 result.
- FIG. 1a A circular catalyst shape is shown in FIG. 1a and the associated arrangement of the stacks (3) is shown schematically in FIG. 1b.
- the dimensions of the stacks (3) are identical. They have a rectangular shape, in the illustration shown here corrugated (4) and smooth (5) sheet metal layers are stacked on top of each other.
- the stacks (3) are arranged such that the lines of contact in the side view give the shape of a right-angled cross (6), which is shown in the drawing by thick lines.
- the stacks (3) are wrapped clockwise around a point of symmetry (8), which is the center of the cross (6) here.
- the metal carrier matrix (1) thus produced is then inserted into a jacket (2).
- the sheet metal layers (4, 5) of the metal carrier matrix (1) and the jacket (2) are connected in the next production step by a joining technique, preferably by soldering.
- FIG. 2 shows a square catalyst shape (with rounded corners).
- the arrangement of the stacks (3) is cruciform, as in the round catalyst shape.
- the individual stacks (3) are not rectangular in the side view, but tapering at the outer end, ie trapezoidal. The manufacturing process proceeds as indicated in the description of FIG. 1.
- Fig. 3a an elongated catalyst shape and in Fig. 3b the associated arrangement of the stacks (3) is shown schematically.
- the arrangement of the stacks (3) is also cruciform.
- the stacks (3) above and below a displacement plane E-E which is perpendicular to the plane of the drawing, are displaced relative to each other, so that a displaced cross (7) results, which is shown in the drawing by thick lines.
- the distance between the stacks (3) perpendicular to the displacement plane E-E determines the width of the catalyst.
- the stacks (3) as already shown in the description of FIG. 1, are wrapped clockwise around the point of symmetry (8), which is arranged on the displacement plane E-E and centrally to both displaced stacks (3). The further production steps take place as already stated above.
- FIGS. 4b and 5b schematically illustrate elliptical catalyst shapes and in FIGS. 4b and 5b the associated arrangements of the stacks (3).
- the arrangement of the stacks (3) is similar to the arrangement shown in Fig. 3b.
- the stacks (3) shown here vary in thickness and length. This results in further different forms for the catalyst. The manufacturing process proceeds as explained in the description of FIG. 1.
- FIG. 6a shows a further embodiment of an elliptical catalytic converter shape
- FIG. 6b shows the associated arrangement of the stacks before devouring
- FIG. 6c shows the associated arrangement of the stacks after devouring.
- the stacks (3) are in the side view parallelogram. They are arranged in a cross shape around the point of symmetry (8) in such a way that a central square cavity (9) is formed.
- the stacks (3) are devoured clockwise around the cavity (9) or the point of symmetry (8), which forms the center of the cavity (9).
- a round shape of the metal carrier matrix (1) results, which is shown schematically in FIG. 6c. Starting from this round shape, the metal support matrix (1) is pressed into the desired elliptical shape using suitable tools.
- the central cavity (9) is closed.
- the metal support matrix (1) is inserted into a jacket (2) and connected to it by joining technology.
- a round catalyst shape is shown, which consists of eight stacks (3).
- Fig. 7b shows the symmetrical arrangement of the eight parallelogram stacks (3) around the point of symmetry (8) before devouring.
- the stacks (3) are the same in thickness and length. Their end faces are brought into contact with the side faces of the respective adjacent stacks (3), the free ends of the stacks (3) are intertwined in the same direction around the point of symmetry (8).
- the metal carrier matrix (1) thus produced is inserted into the jacket (2) and connected to it by joining technology.
