Cooling device for cooling of a sealing means 11 fixed in a non-rotatable member 4, 20 and with a circumferential contact surface on a rotating member 1, 3, 30. A closed ring-formed chamber 8 is arranged in the rotating member 1, 3, 30 radially inside of said sealing means 11. Said chamber 8 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 12 of said chamber 8 is evaporated from the heat generated by said sealing means 11, and where a cooling member 14 is arranged on said rotating member 1, 3 to cool an area radially inside of said chamber 8, such that the gaseous cooling medium is condensed from the cooling effect of said cooling member 14. The invention also relates to a centrifugal separator comprising such a cooling device. |
