A cooling device for cooling of a sealing means fixed in a non-rotatable member and with a circumferential contact surface on a rotating member. A closed ring-formed chamber is arranged in the rotating member radially inside of said sealing means. Said chamber contains an amount of cooling medium which at normal rotating operation is both liquid and gaseous, such that the liquid cooling medium which by centrifugal forces is pressed towards the outer wall of said chamber is evaporated from the heat generated by said sealing means, and where a cooling member is arranged on said rotating member to cool an area radially inside of said chamber, such that the gaseous cooling medium is condensed from the cooling effect of said cooling member. The invention also relates to a centrifugal separator comprising such a cooling device. |
