| Claim: | 1. A flow-guiding hood that guides a flow of air in a computer or an electronic device comprising a plurality of individual parts which comprises: a first flow-guiding element made of a substantially planar first material, shaped such that the first flow-guiding element is composed of two-dimensional regions, each of which are flat and have straight edges, and the first flow-guiding element that channels the flow by providing a main flow channel that causes a rough, approximate flow pattern, and at least one second flow-guiding element made of foamed plastics material as a different, second material and likewise channels the flow, wherein the second flow-guiding element rests on and/or is attached to the first flow-guiding element, and the second flow-guiding element finely controls the flow pattern. |
| Claim: | 2. The flow-guiding hood according to claim 1 , wherein the second flow-guiding element is cut to size, punched or otherwise shaped such that it is defined predominantly by flat faces. |
| Claim: | 3. The flow-guiding hood according to claim 1 , wherein the second flow-guiding element has one or more flat faces adhesively attached over a whole area thereof, to the first flow-guiding element. |
| Claim: | 4. The flow-guiding hood according to claim 1 , wherein the planar material of the first flow-guiding element is foldable, bendable or deformable to form a plurality of flat segments. |
| Claim: | 5. The flow-guiding hood according to claim 1 , wherein the planar material of the first flow-guiding element is a plastics sheet or, a sheet metal or cardboard. |
| Claim: | 6. The flow-guiding hood according to claim 1 , wherein the first flow-guiding element is a punched shaped part. |
| Claim: | 7. The flow-guiding hood according to claim 1 , wherein the first flow-guiding element is divided into a plurality of flat segments. |
| Claim: | 8. The flow-guiding hood according to claim 7 , wherein the flat segments of the first flow-guiding element are differently oriented and are delimited from each other by bends, folds, perforations, punchings or by straight edges. |
| Claim: | 9. The flow-guiding hood according to claim 1 , wherein the first flow-guiding element is shaped so that on a first surface it defines a main flow channel, and all of one or more second flow-guiding elements are attached on a same face of the planar first material of the main channel. |
| Claim: | 10. The flow-guiding hood according to claim 1 , wherein one or more second flow-guiding elements are arranged on a same face of the first planar material of the main channel such that they locally constrict the main flow channel into a plurality of part-flow channels. |
| Claim: | 11. An electronic device comprising the flow-guiding hood according to claim 1 . |
| Claim: | 12. A computer comprising the flow-guiding hood according to claim 1 . |
| Claim: | 13. The flow-guiding hood according to claim 1 , wherein one or more second flow-guiding elements are arranged on a same face of the first planar material of the main channel such that they locally divide the main flow channel into a plurality of part-flow channels. |
| Claim: | 14. A flow-guiding hood that guides a flow of air in a computer or an electronic device comprising a plurality of individual parts which comprises: a first flow-guiding element made of a substantially planar first material, shaped such that the first flow-guiding element is composed of two-dimensional regions, each of which are flat and have straight edges, and the first flow-guiding element that channels the flow by providing a main flow channel that causes a rough, approximate flow pattern, and at least one second flow-guiding element made of foamed plastics material as a different, second material and likewise channels the flow, wherein the second flow-guiding element rests on and/or is attached to the first flow-guiding element, and the second flow-guiding element finely controls the flow pattern, and both the first flow-guiding element and the at least one second flow-guiding element actively channel the flow pattern. |
