The invention provides a liquid cooling charging cable and a preparation method and application thereof. The liquid cooling charging cable sequentially comprises a cable core, an isolating layer and an outer sheath from inside to outside in the radial direction. The cable core comprises a ground wire core, power wire cores, a signal wire core group and signal wire cores; the number of the ground wire core is one, and the number of the power wire cores is four. The ground wire core is located in gaps of the four power wire cores. The signal wire core group and the signal wire core are respectively and independently positioned in a gap between the power wire core and the isolating layer; each power wire core comprises a power wire cooling pipe, a power wire conductor and a power wire insulator from inside to outside. Through the arrangement of the liquid cooling charging cable structure and the technical scheme of taking away heat through liquid cooling, the current-carrying capacity is improved under the condition that the cross section area of a power line conductor is not increased, the purpose of fast charging of a new energy automobile is achieved, and the liquid cooling charging cable is suitable for being used as an electric automobile charging pile cable.

    本发明提供一种液冷充电电缆及其制备方法和应用。所述液冷充电电缆沿径向由内到外依次包括缆芯、隔离层和外护套;所述缆芯包括地线芯、动力线芯、信号线芯组和信号线芯;所述地线芯为一根,动力线芯为四根;所述地线芯位于四根动力线芯间隙;所述信号线芯组和信号线芯各自独立地位于动力线芯和隔离层间隙;所述动力线芯由内到外包括动力线冷却管、动力线导体和动力线绝缘。本发明中通过对液冷充电电缆结构的设置,采用液体冷却带走热量的技术方案,在不增大动力线导体截面面积的情况下,提高了载流量,实现了新能源汽车快充的目的,适用作电动汽车充电桩电缆。
