The invention discloses a light-weight liquid cooling cable for a direct current charging pile and a production process of the light-weight liquid cooling cable. The light-weight liquid cooling cable for the direct current charging pile comprises a cable core, a filling layer, a belting layer and a sheath layer, a belting layer and a sheath layer are sequentially wrapped outside the cable core, and a filling layer is filled between the belting layer and the cable core; the filling layer is made of a PP rope material, the belting layer is made of a non-woven fabric material, and the sheath layer is made of a thermoplastic elastomer material. The production process sequentially comprises the steps of extrusion of the double-crescent skeleton, stranding of the main power core wire conductor, extrusion of the main power core wire, extrusion of the grounding core wire, extrusion of the auxiliary power core wire, extrusion of the control core wire group and the communication core wire group, overall stranding of the cable core and extrusion of the outer sheath. Through the structural design and material combination, the cable has good mechanical strength and anti-aging performance, meanwhile, the temperature of the cable can be effectively controlled under the high-power charging condition, and therefore the overall safety of the charging pile is improved, and the service life of the charging pile is prolonged.
