摘要： The present invention relates to a bypass air/fluid heat exchanger (2) for a turbofan engine. According to the invention, this exchanger (2) comprises: —an annular outer shroud (3) with two walls, an inner wall (32) and an outer wall (31), —an annular inner shroud (4) concentric with the outer shroud (3), —a series of OGV guide vanes (5) which connect said outer shroud to said inner shroud, —and a circulation circuit (6) for circulating said fluid, the two shrouds delimiting a bypass air flow path, the fluid circulation circuit (6) is formed in the body of the outer shroud (3) and in the body of at least one of the OGV guide vanes (5), this circulation circuit (6) opening at the two respective ends thereof into an inlet opening (34) and into an outlet opening (35), formed through said outer wall (31) of the outer shroud, and the two shrouds (3, 4), the OGV guide vanes (5) and the circulation circuit (6) of said fluid are integral.

摘要： The invention relates to a pressurized-air supply unit for an air-jet cooling device cooling an outer casing of a turbomachine turbine. This unit is notable in that it is monobloc, in that it comprises: —a body which has an interior wall provided with air-ejection perforations, an exterior wall and outlet ducts which are configured to be coupled to cooling lines of the cooling device, —an elbowed air-conveying pipe coupled by its outlet opening to said exterior wall of the body, and in that said unit comprises at least one air-distribution partition, arranged in the outlet opening and connecting the internal face of the portion of the air-conveying pipe that is situated facing the body to the internal face of the opposite portion of the air-conveying pipe.
