Abstract
A cooling device for cooling of a seal 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 the seal. The 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 the chamber is evaporated from the heat generated by the seal, and where a cooling member is arranged on the rotating member to cool an area radially inside of the chamber, such that the gaseous cooling medium is condensed from the cooling effect of the cooling member. The invention also relates to a centrifugal separator comprising such a cooling device.
