Abstract:
Heat exchanger (2) of the air-oil type, for an annular air channel in a turbomachine, comprising a heat exchange zone (3) with oil passages (4) and heat exchange surfaces for heat exchange with air, said heat exchange zone forming an axial air passage and having a profile facing the air flow and contained in a plane perpendicular to the air flow, the profile of the heat exchange zone being in the form of a circular arc such that it can be placed in the annular air channel. The heat exchanger is characterised in that it comprises an oil inlet (18) and an oil outlet (20) on a radially inner (14') or radially outer (16') face of the heat exchange zone, the oil passages comprising several paths (22) between the oil inlet and oil outlet, distributed along the circular arc profile of the heat exchange zone.
