Charging gun cooling system and charging gun

A charging gun cooling system, comprising:

• a head cooling assembly comprising a support frame and a cooling cavity, wherein the cooling cavity is provided with a liquid inlet and a liquid outlet, the support frame is configured to accommodate a connection end of a first terminal and a connection end of a second terminal, and the cooling cavity is disposed in the support frame and between the first terminal and the second terminal;
• a liquid inlet pipe communicating with the liquid inlet;
• and
• a liquid outlet pipe communicating with the liquid outlet,
• wherein an outer surface of the liquid inlet pipe is for a first cable to be laid on, an outer surface of the liquid outlet pipe is for a second cable to be laid on, the first cable is connected to the connection end of the first terminal, and the second cable (500) is connected to the connection end of the second terminal,
• wherein the head cooling assembly further comprises a first heat conductive member, and the first heat conductive member is configured to be disposed between the connection end of the first terminal and the cooling cavity and/or between the connection end of the second terminal and the cooling cavity;
• and
• wherein the head cooling assembly further comprises a second heat conductive member, and the second heat conductive member is configured to be disposed between the connection end of the first terminal and the support frame and/or between the connection end of the second terminal and the support frame.
