Abstract
An electrical machine comprising a rotor ( ) mounted on a shaft ( ) for rotation therewith and defining an axis of rotation, and a stator ( ) disposed coaxially with and in opposition to the rotor ( ). The electrical machine further comprises a housing ( ) enclosing the stator ( ) and the rotor ( ), the housing ( ) having a first axial end with a wall with an inner surface and an outer surface and a second axial end with a wall with an inner surface and an outer surface. The electrical machine also includes a first cooling tube ( ′) having a first end and a second end and an embedded portion thereof embedded between the first inner surface and the first outer surface of end wall ( ). A second cooling tube ( ′) has a first end and a second end and an embedded portion thereof embedded between said inner surface and said outer surface of the wall ( ) of the second axial end. The first end ( ) of the first cooling tube and the first end ( ) of the second cooling tube ( ′) are fluidically coupled together to permit fluid flow in parallel between the first cooling tube ( ′) and the second cooling tube ( ′).
