Heat dissipation device for cable gun head through liquid metal isothermal extension coupled with liquid cooling loop

A cable charging cable gun heat dissipation device that couples liquid-metal isothermal spreading with a liquid-cooling circulation, the cable charging cable gun heat dissipation device being disposed inside a charging cable gun of a liquid-cooled ultra-fast charging system, comprising:

• a liquid-metal (LM) heat-source collection chamber;
• a liquid-metal heat conduction tube;
• a liquid-metal heat return tube;
• a heat-exchange coupling chamber;
• a magnetic pump;
• a liquid-cooling return pipe;
• and a liquid-cooling inlet pipe;
• wherein the LM heat-source collection chamber is formed within a conductor of the charging cable gun and is filled with a gallium-based liquid metal;
• an inlet end of the liquid-metal heat conduction tube is in fluid communication with the LM heat-source collection chamber, and an outlet end of the liquid-metal heat conduction tube extends outward to the heat-exchange coupling chamber;
• an outlet end of the liquid-metal heat return tube is in fluid communication with the LM heat-source collection chamber;
• and the magnetic pump is configured to drive circulation of the gallium-based liquid metal through the LM heat-source collection chamber, the liquid-metal heat conduction tube, and the liquid-metal heat return tube to achieve real-time isothermal spreading;
• wherein an inlet end of the liquid-cooling inlet pipe communicates with a reservoir of the liquid-cooled ultra-fast charging system and an outlet end of the liquid-cooling inlet pipe communicates with the heat-exchange coupling chamber;
• an inlet end of the liquid-cooling return pipe communicates with the heat-exchange coupling chamber and an outlet end of the liquid-cooling return pipe communicates with a radiator of the liquid-cooled ultra-fast charging system;
• and the heat-exchange coupling chamber is disposed within a handle of a charging connector and configured to allow heat exchange between the gallium-based liquid metal and a liquid-cooling medium.
