Liquid cooling cable

The utility model discloses a liquid cooling cable. The liquid cooling cable comprises an outer sheath, a grounding wire core, a main wire core, a signal wire core and a control wire core are arrangedin the outer sheath in parallel, a cooling channel is formed in a conductor of the main wire core in the length direction, and a cooling return pipe connected with the main wire core in parallel is further arranged in the outer sheath corresponding to the cooling channel. And the cooling channel and the cooling return pipe are used for circulating cooling liquid. After the cable is installed on acharging pile, the cooling channels are in one-to-one correspondence with the cooling return pipes and are communicated with the cooling return pipes to form a cooling loop, cooling liquid is circularly introduced into the cooling loop to reduce heat of the cable during charging, and the cooling liquid is in direct contact with a conductor in a main wire core, so that the heat dissipation efficiency of the cable can be gr
