Abstract

This document relates to a cooling assembly centered on an axis (X), the cooling assembly comprising: - a cooling circuit intended to be mounted around a housing (18), the cooling circuit including a cooling rail (50) extending circumferentially around the axis (X); - a retaining collar (53) for the cooling rail (50) extending around the cooling rail (50) and including means (56) for securing the retaining collar (53) against the housing (18); and - a ring (58), preferably made of graphite, arranged between the retaining collar (53) and the cooling rail (50), the ring (58) extending around the cooling rail (50) and the retaining collar (53) extending around the ring (58).
