Problems solved by technology

[0003] At present, the liquid-cooled cables on the market generally use the wire core to be directly soaked in the insulating liquid for heat exchange. However, the heat generated by the wire core during use will emulsify the cooling liquid, which increases the occurrence of accidents.

Abstract

The invention discloses a liquid-cooled cable which comprises a sheath tube, at least one positive wire core, at least one negative wire core, a first liquid-cooled tube and a second liquid-cooled tube, wherein the positive wire core and the negative wire core are arranged in the sheath tube; the first liquid-cooled tube and the second liquid-cooled tube are arranged side by side; the positive wire core comprises a positive conductor and a positive insulating layer, and the positive insulating layer is arranged outside the positive conductor in a wrapping manner; the negative wire core comprises a negative conductor and a negative insulating layer; and the negative insulating layer is arranged outside the negative conductor in a wrapping manner. The outer wall of the positive electrode insulating layer and / or the outer wall of the negative electrode insulating layer is coated with a heat-conducting aluminum foil; according to the liquid-cooled cable structure, the heat dissipation problem of the cable is well solved, the structure is simple, and the practicability is high.

Description

technical field [0001] The present invention relates to the technical field of charging cables, and more particularly, to a liquid-cooled cable. Background technique [0002] With the continuous improvement of people's awareness of environmental protection, new energy electric vehicles have been widely promoted in developed countries because of their advantages of no tail gas emissions and no environmental pollution. China's new energy vehicle industry has also experienced rapid growth in the past few years. The development is in the high-speed development stage from the budding period to the growth period. At the same time, the high transmission capacity density, light weight, small size, high flexibility, low heat generation, high safety and high reliability of power transmission and distribution cables are proposed. higher requirement. The liquid-cooled cable is cooled by circulating coolant to ensure that the cable is used at low temperatures, which not only helps to pr...
