The present invention relates to a product for fluidic applications, with at least one surface segment having a plurality of ribs in contact with a fluid flowing in a flow direction and adjacent ribs delimit between them in each case a valley and a method for production and a use of such a product.
The present invention relates to a product for fluidic applications, with at least one surface segment having a plurality of ribs in contact with a fluid flowing in a flow direction and adjacent ribs delimit between them in each case a valley and a method for production and a use of such a product. The product according to the invention can be produced economically with further improved flow properties; in that at least two ribs with the valley they respectively delimit are combined in a group, that at least two groups are present, and separated from each group arranged adjacent to it, viewed transverse to the flow direction S of the fluid, by a valley, and that the height profile of the valley differs in each case from the height profile of the valleys delimited by those ribs of the groups which are adjacent to the valley separating the groups.

1. A product for fluidic applications, comprising at least one surface segment having a plurality of ribs in contact with a fluid flowing in a flow direction, wherein the ribs have a length and a shape, and adjacent ribs delimit between them in each case a valley, wherein in each case at least two ribs with the valley they respectively delimit are combined in a group, andat least two of these groups are present, whereineach group is separated from each group arranged adjacent to it, viewed transverse to the flow direction of the fluid, by a valley,the height profile of the valley separating the respective groups from each other differs in each case from the height profile of the valleys delimited by those ribs of the groups which at the same time are adjacent to the valley separating the groups from each other,the end faces of the ribs against which fluid flows are chamfered or rounded,wherein groups lying behind each other viewed in the flow direction of the fluid are arranged at a distance from each other,wherein a floor of a spacing area present between groups arranged spaced from each other in the flow direction is lower than a floor of the valleys of groups adjacent to the respective spacing area,wherein the groups are arranged offset to each other viewed in the flow direction of the fluid, andwherein at least two ribs of a group have different heights in relation to the floor of the valley separating them from an adjacent group. 2. The product according to claim 1, wherein the valley having a floor separating in each case groups arranged adjacent to each other is lower than the floor of the valleys of the groups adjacent to the valley separating them. 3. The product according to claim 1, wherein groups arranged behind each other viewed in the flow direction of the fluid are positioned offset to each other transverse to the flow direction. 4. The product according to claim 1, wherein groups are arranged behind each other in a row viewed in the flow direction of the fluid. 5. The product according to claim 1, wherein each of the groups comprises at least two subgroups which each comprise at least two ribs and which adjacent ribs delimit a valley, and adjacent subgroups delimit between them in each case a separating valley viewed transverse to the flow direction of the fluid. 6. The product according to claim 5, wherein the height profile of the valley separating the respective subgroups from each other differs in each case from the height profile of the valleys delimited by those ribs of the subgroups which at the same time are adjacent to the valley separating the subgroups from each other. 7. The product according to claim 6, wherein at least two of the subgroups have height profiles differing from each other. 8. The product according to claim 1, wherein more than two groups are present and that at least two groups have a different distance from one of the groups adjacent to them in each case. 9. The product according to claim 1, wherein at the surface coming into contact with the fluid, segments are formed in which groups of ribs and valleys are formed and further comprising at least one segment which is formed flat. 10. The product according to claim 1, wherein it is a flat steel product. 11. A method for producing the product of claim 1, wherein the surface is embossed in a moulding step in a respective segment of the product coming into contact with the fluid. 12. A use of the product of claim 1, for production of pipes which carry a fluid.
