A series cooling method for liquid-cooled cables DC+ and DC- dedicated for DC 600A charging piles

A special DC+ and DC-series-cooled liquid-cooled cable for high-power charging piles, including a liquid-cooled cable insulation jacket, a PE wire arranged in the liquid-cooled cable insulation jacket, and several signal wires. The liquid-cooled cable insulation jacket The quilt is also equipped with two liquid-cooled cables, DC DC+ and DC DC‑, each cable is composed of a soft wire and an outer sheath insulating sleeve. The outer sheath insulating sleeve of the DC DC+ cable is red, and the DC DC‑cable’s The outer sheath insulating sleeve is black, the soft wire is arranged in the outer sheath insulating sleeve, and the gap between the soft wire and the outer sheath insulating sleeve is a coolant channel; one end of the two soft wires are connected respectively There are liquid-cooled terminals of the charging gun, and the other ends are connected with liquid-cooled cable electrodes. The invention effectively prevents the charging gun and the soft wire from overheating during the charging process.
