The embodiment of the invention provides a heat-conducting cable for an electric vehicle, a liquid cooling pipeline is implanted in the cable, and a heat-conducting material is filled between the liquid cooling pipeline and a wire core, so that heat emitted by a conductor is transferred to liquid in the pipeline through the heat-conducting material, and then the heat is taken away through liquid flowing; a power line conductor is designed to be twisted at the inner layer and braided at the outer layer, so that the conductor cannot be loosened in the processing and using processes; and a proper amount of small holes are formed in the wall of the pipeline, liquid can make direct contact with the conductor, the heat conduction efficiency is improved, and a liquid loop is connected with the terminal and the pile base through an insulation or sheath skin layer.
本发明实施例提供了一种电动汽车导热电缆,电缆内植入液冷管道,在液冷管道和线芯间填充导热材料,让导体发出来的热量通过导热材料传递给管道中液体,再通过液体流动将热量带走;动力线导体设计成内层绞合,外层编织,可让导体在加工和使用过程中不会松散;管道壁上开适量小孔,让液体与导体间可以直接接触,增加导热效率,液体回路依靠绝缘或护套皮层与端子和桩座连接。
