<p>The present invention describes a system (100) for cooling a wall element (101) of a device located in a gas turbine. The system (100) comprises a guiding device (102) that is located with respect to the wall element (101) in such a way that a gap (103) between a surface (104) of the wall element (101) and the guiding device (102) is formed. The guiding device (102) comprises a hole (105) for guiding a cooling fluid stream (107) through the guiding device (102) towards the surface (104) in such a way that the cooling fluid stream (107) impinges at the surface (104), so that the cooling fluid stream (107) is heated up to a heated fluid stream (108) after impinging on the surface (104) and the heated fluid stream (108) flows along the surface (104) to an exhaust region of the system (100). Furthermore, the system (100) comprises a fluid deflecting element (109) located inside the gap (103) in such a way that the heated fluid stream (108) is guided around a further cooling fluid stream (107) streaming through a further hole (105) of the guiding device (102).</p> |
