The invention relates to a high-voltage wire harness used in a new energy automobile. The high-voltage wire harness comprises a plurality of cable units, a binding piece and a cooling assembly. The directions of the cable units are consistent, the cable units are arranged on the periphery of the cooling assembly, and the cable units are in contact with the cooling assembly in a heat conduction mode; the binding piece is fixed on the periphery of the plurality of cable units and is used for fixing the positions of the cable units and the cooling assembly; the cooling assembly comprises a cooling pipe and cooling liquid, a containing cavity for containing the cooling liquid is formed in the cooling pipe, the cooling pipe makes contact with the cable unit in a heat conduction mode, and the ends of the cooling pipe extend towards the two sides of the binding piece. In the application, the cooling assembly is arranged in the middle area of the high-voltage wire harness, and the cooling assembly is utilized to absorb heat generated by the cable binding area, so that the heat of the local area of the high-voltage wire harness is reduced, the performance of the cable is improved, and the operation risk of the high-voltage wire harness is reduced.
