Abstract
An electric machine which includes an electrical winding. The electrical winding includes a heat pipe. A heat pipe is a device that relies on a liquid-gas phase transition to transfer heat from a first region of the pipe towards a second region of the pipe. Heat pipes work by using a sealed chamber containing a working fluid. A heat pipe is configured such that the pressure of the working fluid is set so that the working fluid will boil at a first, hotter region of the heat pipe and condense at a second, colder region of the heat pipe.
Claims13
An electric machine comprising an electrical winding, the electrical winding comprising a heat pipe;
- wherein an electrical conductor of the electrical winding at least partly defines a cavity of the heat pipe, the cavity being configured to contain a working fluid of the heat pipe;
- and
- wherein at least a portion of the electrical conductor of the electrical winding comprises at least one region of low conductivity and a plurality of regions of high conductivity arranged such that the electrical conductor provides Litz wire arrangement.
