Embodiment Construction

[0034] now turn Figure 1-Figure 6 , the fluid cooling device 10 according to the first exemplary embodiment will be described.

[0035] The fluid cooling device 10 comprises a thermal storage element in the form of a tubular body 12 and a cooling path in the form of a continuous serpentine cooling tube 14 embedded in the tubular body 12 .

[0036] Tubular body 12 is generally C-shaped and includes an outer surface 16 and first and second longitudinal ends 18 and 20 . Three expansion slots 22 are provided from the first longitudinal end 18 and two expansion slots 24 are provided from the second longitudinal end 20 (see figure 2 ). The expansion slot 22 opens towards the first longitudinal end 18 but does not reach the second longitudinal end 20 . On the contrary, if the image 3 As better seen in the bottom plan view of , the expansion slot 24 opens towards the second longitudinal end 20 but does not reach the first longitudinal end 18 .

[0037] The C-shape of the tubul...

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.

Description

technical field [0001] This invention relates to electric machines. More specifically, the present invention relates to a fluid cooling device for an electric machine and an electric machine provided with such a fluid cooling device. Background technique [0002] Electric machines, motors or generators are well known in the art. It is also widely known that electric machines generate heat as a by-product and that this heat must be somehow removed from the machine in order to improve the performance of the machine and / or prevent premature degradation or failure as a result. [0003] Electric machines are usually air cooled. This is easily accomplished by providing holes in the body of the machine to force air through there. Such cooling devices are inefficient since air is generally an inefficient cooling fluid. Furthermore, the environment in which some electric machines operate makes it impossible to provide the electric machine with holes to allow the passage of air. ...
