Beschreibung
Zusammenfassung:	The invention relates to an annular heat exchanger (12a) having a longitudinal axis (L) for a turbomachine, intended, for example, to be supported by an annular ferrule of a housing of the turbomachine, comprising an annular one-piece part (18) having a first fluid circuit (37) comprising at least one first conduit (38) and at least one second conduit (40) extending in an annular manner, said heat exchanger being characterised in that the first conduit (38) and the second conduit (40) lead into a first cavity (48) formed on a first circumferential end (13) of said annular part (18), and in that it comprises detachable sealing means which are applied to said first end (13) and designed so as to allow a flow of fluid from the second conduit (38) into the first cavity (48) then into the first conduit (40). 本发明涉及一种用于涡轮机的具有纵向轴线(L)的环形热交换器(12a)，所述环形热交换器例如旨在由所述涡轮机的壳体的环形护罩支撑，所述环形热交换器包括整体式环形部分(18)，所述整体式环形部分包括第一回路流体(37)，所述第一回路流体包括环形地延伸的至少第一管道(38)和至少第二管道(40)，其特征在于，所述第一管道(38)和所述第二管道(40)通向在所述环形部分(18)的第一周向末端(13)处形成的第一空腔(48)
