The invention provides a liquid cooling wire holder, an electric drive assembly and a vehicle, the liquid cooling wire holder comprises a wiring shell and a binding post, the wiring shell is provided with a liquid cooling flow channel, the wiring shell is provided with a heat conduction column in the liquid cooling flow channel, and the heat conduction column is internally provided with a mounting hole penetrating through the wiring shell; the binding post is positioned in the mounting hole, and two ends of the binding post are respectively provided with a first terminal and a second terminal; the liquid cooling flow channel is located on the periphery of the heat conduction column, the wiring shell is provided with a flow channel inlet and a flow channel outlet at the two ends of the liquid cooling flow channel respectively, the liquid cooling flow channel is isolated from the installation hole, and the liquid cooling flow channel is arranged in a relatively closed mode. Efficient heat conduction and heat dissipation are carried out through cooling liquid circulating in the liquid cooling flow channel, then the temperature of the wiring shell and the temperature of the binding post are efficiently reduced, the wiring shell can be communicated with cooling flow channels of other equipment through arrangement of the flow channel inlets and the flow channel outlets, and then an additional heat dissipation system does not need to be added; and the cooling arrangement of the liquid cooling wire holder can be simplified.

    本发明提供一种液冷接线座、电驱总成和交通工具,包括接线壳体和接线柱,接线壳体设置有液冷流道,接线壳体在液冷流道内设置有导热柱,导热柱内贯穿接线壳体地设置有安装孔,接线柱位于安装孔内并在两端分别设置有第一接线端和第二接线端;液冷流道位于导热柱的外周,接线壳体在液冷流道的流道两端分别设置有流道入口和流道出口,液冷流道与安装孔相互隔绝,液冷流道呈相对密闭设置。通过液冷流道内流通的冷却液进行高效导热和散热,继而高效降低接线壳体和接线柱的温度,且利用流道入口和流道出口的布置,使接线壳体可与其他设备的冷却流道连通,继而不需要增加额外的散热系统,继而有利于简便液冷接线座的冷却布置。
