Abstract
A cooling assembly including a generally cylindrical body to be inserted inside the generally cylindrical internal stator of an electric machine is described herein. The body includes a cylindrical external contact surface configured and sized to contact the internal surface of the stator. The bottom surface of the body is machine with a channel that is partially closed by a cover to yield a peripheral fluid passage inside the body. An inlet and an outlet aperture are provided.
Claims12
A cooling assembly to be inserted in the internal stator of an electric machine, the internal stator being provided with an internal surface, the cooling assembly comprising:
- a tubular body provided with a gap and an external surface configured and sized as to be applied to the internal surface of the internal stator;
- the tubular body being provided with a bottom surface defining a cooling channel;
- the tubular body being also provided with an inlet and an outlet provided on either side of the gap and open to the cooling channel;
- a cover so configured and sized as to be mounted to the bottom surface so as to close the cooling channel;
- a biasing assembly so mounted to the body in the vicinity of the gap as to selectively bias the external surface of the body against the internal surface of the stator;
- wherein a fluid passage between the inlet and the outlet is defined by the cooling channel closed by the cover.
