Title:
AIR-OIL HEAT EXCHANGER COMPRISING A BYPASS FOR A TURBOMACHINE
Document Type and Number:
WIPO Patent Application WO/2023/099544
Kind Code:
A1
Abstract:
Heat exchanger (2) for an annular air channel in an axial turbomachine, comprising a heat exchange zone (3) with oil passages (4) and heat exchange surfaces (6) forming a heat exchange passage for air, said heat exchange zone being radially delimited by an upper wall (12) and a lower wall (9), the oil passages extending radially and axially between said upper and lower walls, said heat exchange zone having a profile facing the air flow and contained in a plane perpendicular to the air flow, and 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 further comprises a wall (8) having a circular arc profile and being parallel to, and radially away from, the heat exchange zone so as to form a bypass passage (10) for the air, parallel to the heat exchange passage, between said wall and the heat exchange zone.
