FLUID DUCT SYSTEM, TURBO ENGINE WITH A FLUID DUCT SYSTEM AND METHOD FOR THERMAL MANAGEMENT AND/OR VENTILATION

摘要

The invention in particular relates to a fluid duct system (S) for thermal management and/or ventilation of a first region (2a) containing at least one temperature sensitive target (8) within a turbo engine (1), characterized by at least one fluid duct element (4) connecting a second region (3a) with the first region (2a), said first region (2a) having a lower pressure than the second region (3a) at least during operation of the turbo engine (1) and being configured and combined with at least one impingement device (6), so that at least during operation of the turbo engine a pressure gradient is present inside the at least one fluid duct element (4) generating a fluid jet (5) in the first region (2a) that emerges from the at least one fluid duct element (4) towards the at least one impingement device (6) and said fluid jet (5) impinges at least partially on the at least one impingement device (6), where the fluid jet's thermal energy is at least partially reduced in order to use the thus cooler fluid jet (5) for cooling and/or ventilating the first region (2a).
