Abstract
In a gas-cooled electrical machine having an axial fan ( ) and a downstream guidance mechanism, arranged downstream of the axial fan, in order to raise the pressure of a cooling gas, the cooling gas is driven in a forced manner by means of the axial fan from an inlet area ( ), which is bounded by an inner casing ( ) and a partition wall ( ) arranged in the radial plane of the axial fan ( ), into an outlet area ( ) which is bounded by the partition wall ( ) and an outer casing ( ). In this case, the downstream guidance mechanism is designed as a deflection diffusor ( ) in order to deflect a cooling-gas flow ( ) from an essentially axial flow direction to an essentially radial flow direction.
