The present invention relates to the technical field of charging guns, and specifically discloses a liquid cooling system for charging gun and a charging gun. In the liquid cooling system for charging gun, a head cooling assembly comprises a head housing, a first head sealing assembly, a second head sealing assembly, and a third head sealing assembly. The head housing is provided with a terminal interface and a head inlet; a terminal goes through the terminal interface and the connecting end of terminal is accommodated in the head housing; a cable enters the head housing through the head inlet and connects to the connecting end of terminal. The first head sealing assembly is arranged at the joint between the connecting end of terminal and the cable in a sealed manner. The second head sealing assembly is arranged at the terminal port in a sealed manner. The third head sealing assembly is arranged at the head inlet in a sealed manner. An outlet end of a cooling liquid input tube communicates with an inlet end o
