Abstract:
A cooling structure is provided for a dynamo-electric machine. The cooling structure has a refrigerant supply path for introducing a refrigerant into a rotor, and refrigerant outlets that are opened to the refrigerant supply path so that the refrigerant will be splashed onto the coil ends of a stator as the rotor rotates. Blocking wall members are provided in refrigerant splash paths between the refrigerant outlets and the coil ends for blocking a portion of the refrigerant, which splashes from the refrigerant outlets when the rotor rotates. The rate at which the blocking wall members shield the coil ends against the refrigerant is low when the rotor rotates at a low speed and is high when the rotor rotates at a high speed.

Claim (Index 3):
The dynamo-electric machine cooling structure according to  claim 1 , wherein\n the refrigerant outlets are provided on an outer perimeter surface of a rotor shaft that rotatably supports a rotor core, and the blocking wall is configured such that communication passages that connect a refrigerant outlet side and a coil end side are formed in the refrigerant splash path, and that a cross-sectional area of the communication passages is formed larger on a front position side of the refrigerant outlets in an outer diameter direction than on a side away from the front position side in an axial direction.
