Abstract

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.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a liquid metal flexible cable for direct current large current. Background technique [0002] In recent years, with the rapid development of the electric vehicle industry, people have higher and higher requirements for fast charging. [0003] At present, DC high current charging technology is a fast and effective charging method. However, due to the significant Joule heating effect in the cable due to the high DC current, the temperature of the cable will rise sharply during charging, which will greatly reduce the reliability and life of the cable. There are usually two ways to solve the above problems: first, increase the cable area, but because conventional cables use metals such as copper or aluminum, increasing the cable area will also increase the weight and stiffness of the cable, thereby limiting its operability; second, Heat dissipation technologies such as air cooling o...
