Abstract
The present disclosure is directed to systems and methods for cooling an electric charging cable. The system includes a conductor core, a wick placed around an exterior of the conductor core, an outer cover surrounding the wick, wherein the outer cover comprises an inner surface, and wherein a space is formed between the wick and the inner surface of the outer cover, and one or more channels disposed within the space between the wick and the inner surface of the outer cover and coupled to the wick, wherein the one or more channels includes an outer surface and wherein the outer surface of the one or more channels is placed a distance from the inner surface of the outer cover.
Claims18
An electric charging cable comprising:
- a conductor core;
- a wick placed around an exterior of the conductor core;
- an outer cover surrounding the wick, wherein the outer cover comprises an inner surface, and wherein a space is formed between the wick and the inner surface of the outer cover and is operable to receive a cooling fluid;
- one or more channels disposed within the space between the wick and the inner surface of the outer cover and coupled to the wick;
- a pump fluidly coupled to the space between the conductor core and the outer cover and fluidly coupled to the one or more channels;
- and
- a valve coupled to the pump and fluidly coupled to the one or more channels, wherein the valve is operable between a closed position and an open position, wherein:
- the one or more channels is operable to receive one or more of vapor and a cooling fluid, wherein the cooling fluid is disposed within the space between the conductor core and the outer cover,
- the one or more channels comprises an outer surface,
- the outer surface of the one or more channels is placed a distance from the inner surface of the outer cover, and
- at least one first portion of the wick is fluidly coupled to the space and at least one second portion of the wick is fluidly coupled to the one or more channels.
An electric charging cable comprising:
- a conductor core;
- a wick placed around an exterior of the conductor core
- an outer cover surrounding the wick, wherein the outer cover comprises an inner surface, and wherein a space is formed between the wick and the inner surface of the outer cover;
- and
- a plurality of dividers placed between the wick and the inner surface of the outer cover, such that the space is divided by the plurality of dividers into a plurality of zones, wherein each of the zones comprises a spiral pathway between an inlet of the space and an outlet of the space.
