The invention discloses a preassembled electric vehicle liquid cooling charging cabin, and relates to the technical field of charging cabins, the preassembled electric vehicle liquid cooling charging cabin comprises a charging cabin outer box and a liquid cooling heat dissipation mechanism, the charging cabin outer box is internally provided with a plurality of charging cabinets, and the top of the charging cabin outer box is provided with the liquid cooling heat dissipation mechanism extending into the charging cabin outer box; the liquid cooling heat dissipation mechanism dissipates heat of the charging cabinet, damping assemblies located on the side faces of the charging cabinet are installed on the left side and the right side of the charging cabin outer box, universal wheels are installed at the bottom of the charging cabin outer box, and the liquid cooling heat dissipation mechanism further comprises a liquid supplementing and discharging assembly. The support plate is mounted on the side surface of the charging cabin outer box and extends to the top of the support plate; according to the charging cabinet, cooling and heat dissipation can be carried out in the mode that cooling liquid absorbs the outside and extracts internal air, so that the gas for cooling and heat dissipation of the charging cabinet is low-temperature gas, the requirement for cooling and heat dissipation of the charging cabinet in high-temperature weather is met, meanwhile, the high-temperature air in the charging cabinet is extracted and discharged in a matched mode, and the cooling efficiency is improved. And the heat dissipation and cooling efficiency of the charging cabinet is improved.
