Abstract
Systems and methods are provided to cool a heat producing component in an electrical machine system. The electrical machine includes a supercritical carbon dioxide (SCO2) wherein the SCO2 is a working medium of a heat exchanger that is arranged in the electrical machine system to cool a fluid that cools the heat producing component and/or wherein the SCO2 directly cools at the heat producing component.
Claims13
A system comprising:
- a heat exchanger comprising a supercritical carbon dioxide (SCO2) as a working medium,
- a generator comprising a stator, and a rotor rotatable relative to the stator, the stator and the rotor are heat generating components;
- and
- a closed fluid loop between the at least one heat generating component and the heat exchanger, the heat exchanger arranged to receive a fluid from the at least one heat generating component to be cooled by the heat exchanger, and transmit the cooled fluid to the heat generator component,
- wherein the working medium is heated during the heat exchange to form a heated working medium.
2 more elements
A method comprising:
- transmitting a fluid in a closed loop, wherein the fluid flows from component of a generator, subsequently through a heat exchanger where the fluid is cooled, and the cooled fluid flow to the component;
- and
- cooling the generator component with the cooled fluid,
- wherein when component is a stator and/or a rotor,
- wherein SCO2 is a working medium of the heat exchanger.
