摘要： In a gas-cooled electrical machine having an axial fan (12a) 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 (41), which is bounded by an inner casing (21) and a partition wall (20) arranged in the radial plane of the axial fan (12a), into an outlet area (42) which is bounded by the partition wall (20) and an outer casing (37). In this case, the downstream guidance mechanism is designed as a deflection diffusor (36) in order to deflect a cooling-gas flow (39) from an essentially axial flow direction to an essentially radial flow direction.

摘要： In a generator with a cooling system which draws in, from the generator, cooling medium heated by the heat-generating elements of the generator and which guides the hot cooling medium to at least two cooling units (23), which cooling units (23) operate in parallel and cool the cooling medium before it is led back to the heat-generating elements of the generator, operation substantially uninfluenced by failures of the cooling units (23) is made possible by means being provided which mix together the cooling medium flows (31) flowing from the different cooling units (23) after they emerge from the cooling units (23) and before they are supplied to the heat-generating elements of the generator.
