Abstract
A high voltage power conductor assembly includes a tubular electrical conductor having an inner surface with protrusions that define a channel for receiving coolant from a cooling system to remove heat from the conductor, and an outer insulation surrounding the tubular electrical conductor. The protrusions increase surface area and promote turbulence of coolant flow within the channel, enhancing heat transfer from the conductor to the coolant. The outer insulation electrically isolates the conductor while allowing efficient heat evacuation, thereby improving thermal management in high voltage applications.
Claims20
A high voltage power conductor assembly, comprising:
- a tubular electrical conductor having an inner surface with protrusions for increasing heat transfer, the inner surface defining a channel configured for receiving a coolant from a cooling system designed to evacuate heat from the tubular electrical conductor to the coolant when in use;
- and
- an outer insulation surrounding the tubular electrical conductor.
A method of cooling a high voltage power conductor assembly while charging a battery, comprising:
- providing a high voltage power conductor assembly including a tubular electrical conductor having an inner surface with protrusions for increasing heat transfer, the inner surface defining a channel configured for receiving a coolant from a cooling system designed to evacuate heat from the tubular electrical conductor to the coolant when in use and an outer insulation surrounding the tubular electrical conductor;
- connecting the tubular electrical conductor to a battery and an electricity source such that the battery can be charged;
- and
- connecting a coolant system such that a coolant can circulate within the channel and evacuate heat produced by the tubular electrical conductor.
