Abstract

A liquid cooling arrangement for electric machines uses a continuous cooling tube associated with a heat storing element. The cooling tube has a serpentine configuration and the heat storing element includes longitudinal slots starting from both longitudinal ends of the heat storing element. Accordingly, it is possible to slightly deform the heat storing element to properly position it into the internal stator of an electric machine. An internal biasing assembly may be used to force the external surface of the heat storing element to the internal surface of the stator.
