1. A liquid cooling system of a charging gun, comprising:
a head cooling assembly comprising a cooling pipe assembly connected to a charging terminal of the charging gun;
a tail cooling assembly comprising a connection box and a first conductive member, wherein one end of the first conductive member is disposed in the connection box, a cable connected to the charging terminal is connected to the first conductive member in the connection box, and another end of the first conductive member is connected to an external power supply; and
a liquid input pipe and a liquid output pipe, wherein the liquid input pipe extends through the connection box and is in communication with an inlet of the cooling pipe assembly, and the liquid output pipe is in communication with an outlet of the cooling pipe assembly,
wherein the charging terminal is provided with a cooling groove, and the cooling pipe assembly is inserted in the cooling groove;
wherein an extension direction of the cooling groove is consistent with an extension direction of the charging terminal, an opening of the cooling groove is disposed at a wiring terminal of the charging terminal, the cooling pipe assembly comprises an elongate cooling pipe, and the elongate cooling pipe is inserted in the cooling groove;
wherein a sidewall of the charging terminal is provided with an outlet channel and an inlet channel that are in communication with the cooling groove, and the cooling pipe assembly further comprises a water inlet cooling pipe and a water outlet cooling pipe, wherein one end of the water inlet cooling pipe extends into the inlet channel and is in communication with the elongate cooling pipe, another end of the water inlet cooling pipe is in communication with the liquid input pipe, one end of the water outlet cooling pipe extends into the outlet channel and is in communication with the elongate cooling pipe, and another end of the water outlet cooling pipe is in communication with the liquid output pipe; and
wherein the cooling pipe assembly further comprises a diverter member, the diverter member is disposed in the elongate cooling pipe and between the water inlet cooling pipe and the water outlet cooling pipe, and the diverter member is configured to allow a liquid in the water inlet cooling pipe to bypass the diverter member in the elongate cooling pipe and then enter the water outlet cooling pipe.
