The invention relates to the technical field of cables, and provides a
liquid metal flexible cable for a
direct current high current. The cable comprises a flexible pipeline group and two conductive units, wherein the interior of each conductive unit is provided with a
liquid metal flow channel; the flexible pipeline group comprises two flexible pipelines; one ends of the two flexible pipelines are communicated with an inlet and an outlet of one of the
liquid metal flow channels respectively, and the other ends are communicated with the inlet and the outlet of the other liquid
metal flow channel respectively; a plurality of permanent
magnet pairs are arranged on the liquid
metal flow channels along the length direction of the liquid
metal flow channels; each permanent
magnet pair comprisestwo permanent magnets which are arranged on the upper side and the lower side of each liquid
metal flow channel respectively, and the N poles and the S poles of the two permanent magnets are oppositely arranged. According to the cable,
high conductivity is ensured, and the continuously flowing liquid metal can also be used for heat dissipation. In addition, the liquid metal has high flexibility and deformability, so that the flexibility of the cable is greatly improved; and the liquid metal is easy to recycle, so that the loss is extremely low.
