US 2016/0241111 A1 · DEVICE FOR DEFLECTING AT LEAST A PORTION OF A COOLING FLUID LOWING AXIALLY IN AN INTERMEDIATE SPACE WHICH IS ARRANGED BETWEEN A ROTOR AND A STATOR OF A ROTATING ELECTRICAL MACHINE

Abstract

A device for deflecting at least a portion of a cooling fluid flowing axially in an intermediate space is arranged between a rotor and a stator of a rotating electrical machine, in particular of a turbogenerator, wherein at least one blade can be arranged on a prespecifiable section of an outer face of the rotor and in the intermediate space, which blade is designed and can be arranged in such a way that a portion of the cooling fluid flowing in the intermediate space can be radially deflected in the direction of the stator by said blade.

Dependent claims

A device for deflecting at least a portion of a cooling fluid that is flowing axially in an intermediate space that is arranged between a rotor and a stator of a rotating electrical machine, comprising:

at least one blade arranged on a predetermined section of an outer face of the rotor and in the intermediate space, said blade arranged in such a manner that a portion of the cooling fluid that is flowing in the intermediate space is deflected towards the stator by means of said blade,
at least one connecting element connecting the blade to the rotor, and
at least one outlet opening that extends parallel to the longitudinal axis of the rotor arranged on the contacting element such that a portion of the cooling fluid that makes contact with the connecting element can flow axially through said outlet opening.

Dependencies are inferred from the claim text.
