Abstract
A cooling device () for a turbine of a turbomachine extending along an axis includes at least one radially inner metal sheet () and one radially outer metal sheet () that are joined to one another and delimit, between them, cooling air circulation channels () extending circumferentially from a connection region (). Each channel () includes at least one air inlet and air ejection orifices (), that are designed to be oriented toward a region to be cooled. The cooling device also includes at least one cooling duct () intended for the circulation of cooling air, the duct () located radially outside said metal sheets () and close to or in contact with the metal sheets so as to cool said metal sheets using the cooling air circulating in the duct (), the cooling duct () extending axially and arranged toward the circumferential end regions of the channels ().
