The invention provides a direct current liquid cooling charging cable and a preparation method thereof, and relates to the technical field of electric vehicle charging cables, the cable comprises two power lines, a protection line and a liquid return pipe are arranged in a gap between the two power lines, and auxiliary power lines are arranged in gaps between the two power lines and the protection line. A control line and a signal line are respectively arranged in gaps between the two power lines and the liquid return pipe, filling pieces are arranged in gaps among the power lines, the protection line, the auxiliary power line, the control line, the signal line and the liquid return pipe, the power lines, the protection line, the auxiliary power line, the control line, the signal line, the liquid return pipe and the filling pieces are wrapped by a wrapping tape to form a wire core group, and an outer sheath is sleeved outside the wire core group. The hollow pipeline and the liquid return pipe are arranged in the conductor, the cable conductor is kept at a low temperature in the charging process through the liquid cooling technology, damage to a charging pile and a charging cable caused by heating of the conductor is overcome, the high-power rapid charging capacity of an electric vehicle is achieved, and the charging time of the electric vehicle is shortened.
本发明提供一种直流液冷充电电缆及其制备方法,涉及电动汽车充电电缆技术领域,电缆包括两根动力线,两根动力线之间空隙分别设置保护线和回液管,两根动力线和保护线之间空隙处均设置辅助动力线,两根动力线和回液管之间空隙处分别设置控制线和信号线,动力线、保护线、辅助动力线、控制线、信号线、回液管的空隙处设置填充件,动力线、保护线、辅助动力线、控制线、信号线、回液管、填充件经包带绕包构成线芯组,线芯组外套设外护套。本发明通过在导体内部设置中空管道和回液管,采用液冷技术使电缆导体在充电过程中保持较低的温度,克服导体发热对充电桩、充电电缆的损伤,从而实现对电动汽车大功率快速充电能力,来缩短电动汽车充电时间。
