Definitions
- the object of the invention relates to a flat structure and to a honeycomb body.
- EP-0 454 712 B1 describes a flat structure which is formed from a metal foil.
- the flat structure has at least two structures spaced apart from one another and at least partially overlapping.
- the overlapping structures are designed in the form of grooves or grooves.
- the structures have different dimensions.
- One structure forms so-called macro structures.
- the other structures form so-called microstructures.
- the microstructures overlay the macrostructures.
- EP-0 454 712 B1 also discloses a honeycomb body which has a plurality of channels through which a fluid can flow in a flow direction.
- the honeycomb body is formed from at least one flat structure. The channels are limited by the structures of the flat structure.
- a further embodiment of a flat structure which is particularly suitable for building a honeycomb body, is known from WO 96/09892.
- the flat structure has partially overlapping structures. Macrostructures and microstructures are also provided for this flat structure.
- the microstructures run at an angle to the macrostructures. From WO 96/09892 it can also be seen that the microstructures also cross. In particular, the microstructures cross on the wave crests of the macrostructures.
- the flat structure according to WO 96/09892 consists of a metal foil into which the structures are introduced.
- problem areas arise which lead to a high material stress on the structure during a forming process.
- WO 96/09892 also describes a metallic honeycomb body with a plurality of channels made of metal foils through which a fluid can flow in a flow direction and which are at least partially provided with at least one macrostructure forming the channels, which determines the honeycomb shape of the metallic honeycomb body, part of which Sheets are provided with additional microstructures at least in partial areas, and the microstructures run at an angle to the direction of flow and follow one another at intervals, the microstructures crossing one another.
- a flat structure which has structures.
- the structures are in the form of webs which are pressed out in a bridge shape from a plane of the flat structure.
- the webs are arranged next to one another in longitudinal and parallel zones.
- the webs are protruding out of the plane of the metal foil on both sides.
- the webs protruding on both sides are produced in that an initially flat metallic smooth band is passed through a pair of embossing cutting rollers through which the band is partially slotted and the webs on both sides of the plane of the Tape are pushed out.
- the present invention has for its object to provide a flat structure which is easier to manufacture and process. Another object of the invention is to provide a honeycomb body that is easier to manufacture.
- the flat structure according to the invention which has at least two partially overlapping structures spaced from a reference surface, is characterized in that at least one opening is provided which is formed in an area in which the structures overlap.
- the structures overlap, for example by crossing or bumping into each other. In these areas, the flat structure is particularly stressed when the structures are produced if the structures are produced by a shaping process. Furthermore, folds, faults or the like can occur in the area of the superimposed structures. This is avoided by forming at least one opening in the area of the superimposed structures.
- the opening is preferably formed by at least one slot.
- an embodiment of the opening is preferred, in which at least two slots are provided, which meet, in particular cross, at an angle. This ensures optimal material utilization.
- the opening be formed by at least one perforation.
- the at least one opening is preferably introduced into the flat structure before the structures are formed.
- the formation of the openings and the structures can be synchronized, so that the openings are always produced at a predetermined location of the flat structure.
- the configuration of the flat structure according to the invention also enables structures which have a similar geometry to be superimposed, in particular if they form relatively large structures within the flat structure, since the perforation removes the possible problem zone before the forming process.
- a flat structure which has at least two structures spaced apart from one another and at least partially overlapping.
- the flat structure has at least one opening which is formed in an area in which the overlapping structures have a common one have a theoretical maximum height in relation to the reference surface that is greater than a maximum height of at least one structure in this area.
- the entire edge of the opening lies at a level related to the reference height, which is smaller than the theoretical maximum height.
- the distance of the edge of the opening to the reference surface preferably corresponds to the height of the superimposed structure.
- the flat structure have structures that are essentially wave-shaped.
- the wavy structures can intersect at an angle, for example.
- the structure as a whole can assume a wavy configuration, it can be wound due to the perforations within the respective structural surfaces.
- the wavy structures can also meet at an angle.
- further processing of the planar structure is simplified by the formation of the openings in the superimposition area of the structures.
- structures of different cross-sectional geometry can be formed.
- the configuration of a structure which has an essentially V-shaped cross section is preferred.
- the perforations also make it possible to form structures which have different geometries when viewed in a longitudinal direction of the structure and / or shape, the opening being formed between two adjacent, different structures.
- the structures can also be designed such that they have a longitudinal extension, the structures having at least two adjacent longitudinal sections which are directed essentially perpendicularly in the opposite direction to the reference surface. In this way, a simpler, opposite curl of the flat structure can be achieved.
- a flat structure in which at least one structure forms a primary structure and at least one structure forms a secondary structure, the primary structure having a larger amplitude than the secondary structure.
- the primary structure can be a macro structure.
- the secondary structure can be a so-called micro structure.
- An embodiment of the flat structure is preferred in which secondary structures overlap on the primary structures.
- secondary structures overlap, in particular cross, on a wave crest or in the wave trough of the primary structures.
- the flat structure preferably consists of a metallic material.
- the flat structure can be designed, for example, like a net.
- a flat structure which is formed by a metal foil is preferred.
- a honeycomb body with a plurality of channels through which a fluid can flow in a flow direction is proposed.
- the honeycomb body is formed by at least one flat structure. It has at least two structures which are spaced apart from one another and at least partially overlapping and which form the Limit channels.
- the honeycomb body is characterized in that at least one opening is provided in at least one area in which the structures overlap. The formation of the opening ensures that the honeycomb body is easier to manufacture, because where structures at least partially overlap, the structure is given a certain elasticity by the at least one opening, which makes it possible, for example, to form the honeycomb body by spirally winding the structure.
- a further advantage of the configuration can be seen in the fact that the structures in the areas in which the structures overlap are not exposed to increased mechanical stress during the production of the structures.
- the opening is preferably formed by at least one slot.
- the openings are expediently formed by a plurality of slots which meet at an angle, in particular intersect, at one another.
- the opening can also be designed in the form of at least one perforation.
- a honeycomb body with a plurality of channels through which a fluid can flow in a flow direction which has at least one flat surface
- the honeycomb body is characterized in that at least one opening is provided, which is formed in an area in which the superimposed structures have a common theoretical maximum height in relation to the reference surface, which is greater than a height of at least one structure therein
- the honeycomb body has the advantage that layers of the structure lie better against one another, since the tips formed by the superimposition of the structures, as are known, for example, from WO 96/09892, are eliminated.
- the honeycomb body is configured as a metallic honeycomb body, in which the flat structures are formed by metal foils, simplified soldering of the metal foils to one another and / or to a metal tube is also achieved.
- the opening also opens up a possibility of connecting the structures by means of suitable connecting means, for example pins, the connecting means extending through the openings. This can also be achieved in an embodiment of the honeycomb body according to claim 15.
- the honeycomb body is preferably designed such that the structures are essentially undulating.
- At least one structure form a primary structure and at least one structure form a secondary structure, the primary structure having a larger amplitude than the secondary structure.
- the structures are preferably designed such that the secondary structures overlap on the primary structures.
- the superimposition of the secondary structures takes place on the wave crests of the primary structures or in wave troughs of the primary structures.

- Other cross sections are possible.
- the configuration of the cross section can be designed according to the requirements for the metal foil 1.
- the invention proposes that an opening (not shown) be formed in the region 5.
- the opening is preferably dimensioned such that it corresponds at least to the area 5, so that the edges 7 lying between the structures 3, 4 are removed, as a result of which the structures 3, 4 are not connected to one another.
- FIG. 2 shows a metal foil 1 with structures 3, 4 which are essentially V-shaped in cross section.

- FIG. 5 shows a modification of the arrangement of the structured metal foil and a smooth metal foil 12 shown in FIG. 4.
- the metal foil 9 differs from the metal foil 8 shown in FIG. 4 in that the secondary structures 14 are not only on the wave crests 15 but also cross in the trough 17 and on the flanks 18 of the primary structures.
- the intersecting secondary structures are formed at an angle to the flow direction R of a fluid F. Openings 16 are formed in the intersection areas or overlay areas of the secondary structures 14, so that the secondary structures 14 do not have a common connecting edge.
