Abstract
A liquid cooled cable (1) includes a conductor (2) with at least two cable strands (3). The conductor (2) is encompassed by a hose (5) spaced in a sectional view at least partially apart from the conductor (2) by an interstitial space (6). The interstitial space (6) is arranged between an inner wall (7) of the hose (5) and the cable strands (3) of the conductor (2). The interstitial space (6) conducts a cooling liquid (15) along the conductor (2).
Claims15
A liquid cooled cable (1) comprising:
- a. a conductor (2) including at least two cable strands (3), wherein the at least two cable strands (3) comprise wires (4) stranded with respect to each other, wherein the wires (4) of a cable strand (3) are mechanically compressed with respect to each other, thereby increasing a higher area current carrying cross-section, wherein the wires (4) comprise copper;
- b. the conductor (2) encompassed by a hose (5) spaced at least partially apart from the conductor (2) by an interstitial space (6) arranged between an inner wall (7) of the hose (4) and the cable strands (3) of the conductor (2), wherein the inner wall (7) of the hose (5) comprises a diameter in the range of 5% to 15% bigger than a diameter of an envelope curve (9) of the corresponding conductor (2);
- c. the interstitial space (6) including a cooling liquid (15) in the hose (5) along the conductor (2).
A method for making of a liquid cooled cable (1) comprising the following steps:
- a. providing a conductor (2) including at least two cable strands (3), the at least two cable strands (3) including wires (4) stranded with respect to each other, wherein the wires (4) of a cable strand (3) are mechanically compressed with respect to each other, thereby increasing a higher area current carrying cross-section, wherein the wires (4) comprise copper;
- b. encompassing the conductor (2) with a hose (5) extruded over the at least two cable strands (3) in a continuous manner spaced at least partially apart from the conductor (2) by an interstitial space (6) arranged between an inner wall (7) of the hose (5) and the cable strands (3) of the conductor (2), wherein the inner wall (7) of the hose (5) comprises a diameter in a range of 5% to 15% larger than a diameter of an envelope curve (9) of the corresponding conductor (2);
- and
- c. conducting a cooling liquid (15) within the interstitial space (6) in the hose (5) along the conductor (2).
