Abstract
The invention refers to a device and a method for cooling a bearing of a centrifugal separator. Through a portion (11, 21) adjacent to the bearing extends at least one channel (15, 23), which is arranged to receive a flow of a cooling medium and comprises at least two successive channel portions (23) and at least one connecting portion (24) provided between successive channel portions. The connecting portion (24) is arranged to provide such a mixing of the cooling medium in the flow through the channel that the flow has an essentially uniform velocity profile immediately after the connecting portion.
