摘要:
Panel (10) for heat exchange and noise reduction for a turbomachine, in particular of an aircraft, the panel comprising: an external surface (22) intended to be swept by an airflow and from which fins (26) extend along a first and a second main predetermined direction; cavities (20) forming Helmholtz resonators, linked to the first ends of channels (30) for the passage of air, the second ends of which communicate with said airflow, such that said channels form necks, referred to as Helmholtz resonators, extending substantially along the first direction; and at least one oil flow chamber (16) extending between said external surface and said at least one cavity, and intended to discharge the thermal energy carried by the oil, characterized in that said channels are formed, at least in part, inside said fins.
