Abstract

The present embodiment comprises an outer tube; and at least one charging line disposed inside the outer tube, in which an outer flow path through which cooling fluid passes is formed between the outer tube and the at least one charging line, the charging line comprises at least one charging conductor; and an insulating body surrounding the outer circumference of the at least one charging conductor, and in which an inner flow path through which cooling fluid passes is formed in the insulating body.

First claim

The invention claimed is:

1. A charging cable comprising:
an outer tube; and
at least one charging line disposed inside the outer tube,
wherein an outer flow path through which cooling fluid passes is formed between the outer tube and the at least one charging line,
wherein the charging line comprises:
at least one charging conductor; and
an insulating body surrounding an outer circumference of the at least one charging conductor, and
wherein an inner flow path through which cooling fluid passes is formed in the insulating body,
wherein the insulating body comprises:
an inner circumference forming the inner flow path; and
an outer circumference spaced apart from an inner circumference of the outer tube.

2. The charging cable of claim 1 ,
wherein the inner flow path is formed inside the insulating body.

3. The charging cable of claim 1 , further comprising:
a cooling fluid supply unit configured to supply cooling fluid to the inner flow path, and
a cooling fluid recovery unit through which the cooling fluid passing through the outer flow path is guided.

4. The charging cable of claim 3 ,
wherein a cross-sectional area of the inner flow path is smaller than a cross-sectional area of the outer flow path.

5. The charging cable of claim 1 ,
wherein the insulating body comprises peaks and valleys which are alternately formed in a circumferential direction.

6. The charging cable of claim 1 ,
wherein the insulating body comprises uneven portions.

7. The charging cable of claim 1 ,
wherein the insulating body comprises a porous member.

8. The charging cable of claim 1 ,
wherein a flow guide protrudes from the insulating body to guide a flow of cooling fluid.

9. The charging cable of claim 8 ,
wherein the flow guide has a spiral shape.

10. A charging cable comprising:
an outer tube; and
at least one charging line disposed inside the outer tube.
wherein an outer flow path through which cooling fluid passes is formed between the outer tube and the at least one charging line,
wherein the charging line comprises:
at least one charging conductor; and
an insulating body surrounding an outer circumference of the at least one charging conductor, and
wherein an inner flow path through which cooling fluid passes is formed in the insulating body.
wherein the insulating body comprises a plurality of insulating portions surrounding the charging conductor, and
wherein adjacent insulating portions are connected to a bridge portion.

11. The charging cable of claim 10 ,
wherein the bridge portion comprises a cooling fluid recovery hole through which cooling fluid passes.

12. The charging cable of claim 11 ,
wherein the cooling fluid recovery hole is formed to be long in a longitudinal direction of the insulating body.

13. A charging cable comprising:
an outer tube; and
at least one charging line disposed inside the outer tube,
wherein an outer flow path through which cooling fluid passes is formed between the outer tube and the at least one charging line,
wherein the charging line comprises:
at least one charging conductor; and
an insulating body surrounding an outer circumference of the at least one charging conductor, and
wherein an inner flow path through which cooling fluid passes is formed in the insulating body,
the charging cable further comprising:
a communication line disposed inside the outer tube,
wherein the inner flow path is formed inside an inner circumference of the insulating body, and
wherein the outer flow path is formed between an outer circumference of the charging line, an outer circumference of the communication line, and an inner circumference of the outer tube.

14. The charging cable of claim 13 , further comprising:
a supporter disposed inside the outer tube,
wherein the supporter comprises:
a charging line through-hole through which the charging line passes, and
a communication line through-hole through which the communication line passes, and
wherein the supporter supports the charging line and the communication line so that the outer circumference of the charging line and the outer circumference of the communication line are spaced apart from the inner circumference of the outer tube.
