According to the charging pile liquid cooling system, a cooling liquid distribution unit distributes cooling fluid in a charging pile body and transfers heat from the charging pile body to an external circulating cooling water system; the cooling liquid distribution unit comprises a first side pipeline and a second side pipeline, the first side pipeline is communicated with an external circulating cooling water system and used for absorbing heat in the charging pile body, the second side pipeline is communicated with the water tank and the cold plate, the second side pipeline, the cold plate and the water tank form cooling circulation, and the charging gun is detachably and electrically connected with a charging gun base of the new energy automobile. The charging gun and the charging cable are provided with a liquid cooling flow path for heat exchange, the expansion valve, the charging gun, the charging cable and the compressor form a closed refrigeration compression cycle, and the refrigeration compression cycle is at least partially arranged on the cold plate; and the closed cooling tower, the pump and the primary side pipeline form a heat dissipation loop.
