Abstract
A nacelle of a turbine engine includes an external cowling, an internal cowling, and a heat exchanger associated with at least one circulation duct for a fluid. In particular, the circulation duct forms a recirculation loop through the heat exchanger, and the recirculation loop includes at least one circulation area extending at least partially along the external cowling in contact with a wall of the external cowling so as to allow exchange of heat by conduction with the air outside the nacelle.
Claims20
A nacelle of turbine engine having a substantially tubular structure, comprising:
- at least one outer fairing defining an outer aerodynamic surface;
- at least one inner fairing defining an internal aerodynamic flow surface, said outer and inner fairing surfaces being connected upstream by a leading edge wall forming an air inlet lip;
- and
- at least one heat exchanger between a first fluid to be heated and a second fluid to be cooled,
- wherein said least one heat exchanger is associated with at least one circulation duct of the first fluid to be heated forming at least one recirculation loop through said at least one heat exchanger, the at least one recirculation loop comprising at least one circulation area of the first fluid extending at least partially along the outer fairing in contact with at least one wall of said outer fairing, wherein said at least one circulation area is configured to allow a heat exchange by conduction with outside air of the nacelle.
