Surface heat exchanger for a nacelle of a turbine engine, and turbine engine nacelle equipped with such a heat exchanger

Turbine-engine nacelle comprising an external structure and an internal structure delimiting an annular secondary-flow duct, said nacelle comprising a housing for a turbine engine, delimiting with the internal structure an annular primary-flow duct, the nacelle comprising at least one surface heat exchanger secured either to the external structure, on the secondary-duct side or on the side external to said external structure, or to the internal structure, on the secondary-duct side or on the side of the primary duct, the surface heat exchanger comprising a first metal sheet and a second metal sheet connected together and at least three distribution channels disposed between the first metal sheet and the second metal sheet, the exchanger furthermore comprising an inlet hydraulic interface and an outlet hydraulic interface, each of the distribution channels being connected directly to the inlet hydraulic interface and to the outlet hydraulic interface, wherein the distribution channels are regularly distributed over the whole of the circumference of the inlet hydraulic interface and/or of the outlet hydraulic interface, and wherein the distribution channels each comprise an inlet end and an outlet end each having a curved form.
