1. A cable assembly comprising:

  • a cable comprising;

    a conductor having a length between a first end of the cable and a second end of the cable; and

    a fluidic channel structure that surrounds the conductor along the length of the cable, wherein the fluidic channel structure comprises;

    a passivation layer surrounding the conductor along the length of the conductor;

    a polymer layer surrounding the passivation layer along the length of the conductor;

    a support structure disposed between the passivation layer and the polymer, wherein the passivation layer, the polymer layer, and the support structure form a fluidic channel surrounding the conductor along the length of the cable;

    a first pump connector coupled to a first end of the fluidic channel structure, the first end of the fluidic channel structure corresponding to the first end of the cable;

    a second pump connector coupled a second end of the fluidic channel structure, the second end of the fluidic channel structure corresponding to the second end of the cable; and

    a liquid-metal pump coupled to at least one of the first pump connector or the second pump connector, wherein the liquid-metal pump pumps liquid metal through the fluidic channel, wherein motion of the liquid metal through the fluidic channel distributes heat away from the conductor.
