A special liquid-cooled cable for DC 600a charging gun of new energy vehicles

Abstract

The invention discloses a special liquid-cooled cable for a new energy automobile direct current 600A charging gun. The special liquid-cooled cable comprises a liquid-cooled cable insulating jacket (1) and a PE wire (11) and a plurality of signal wires (10) arranged inside the liquid-cooled cable insulating jacket (1), wherein the liquid-cooled cable insulating jacket (1) is further internally provided with a direct current DC+ liquid-cooled cable and a direct current DC- liquid-cooled cable. Moreover, the tail of the liquid-cooled terminal of the special liquid-cooled cable for the new energyautomobile direct current 600A charging gun is arranged to be bent, the bent cavity of the charging gun can be adapted preferably, the deformation of an outer sheath insulating sleeve of the liquid-cooled cable when passing through the bent cavity of the charging gun is effectively avoided or reduced, and cooling passage smoothness of the liquid-cooled cable can be guaranteed effectively. Finally, the purpose of effectively avoiding an overheating phenomenon in the charging process of terminals and soft wires of the charging gun is reached.

Description

technical field [0001] The present invention relates to the technical field of high-power charging piles, and specifically relates to a liquid-cooled cable specially adapted to a charging gun bending cavity for high-power charging piles. The connector is connected to the charging gun. The liquid-cooled terminal is just suitable for the bending cavity of the charging gun, ensuring that the insulating sleeve of the outer sheath of the liquid-cooled cable passes through the bending cavity of the charging gun without deformation or with minimal deformation, ensuring that the liquid-cooled cable The coolant channels can be unobstructed. The coolant channels of the DC+ and DC- two liquid-cooled cables are connected in series in the charging gun, and the coolant circulates between the DC+ and DC- two liquid-cooled cables for cooling. Background technique [0002] As we all know, with the promotion and application of new energy electric vehicles in developed countries in the world,...

Problems solved by technology

The charging gun is composed of a gun body and a charging plug. There is a curved cavity between the gun body handle of the charging gun and the charging plug of the charging gun. The liquid-cooled cable is connected to the charging gun. The liquid-cooled cable must pass through the curved cavity of the charging gun. This is not a problem for dry-type integrated cables, but it is a problem for liquid-cooled cables. The problem is related to the minimum bending radius of the liquid-cooled cable, and the outer sheath insulation sleeve of the liquid-cooled cable is in the bending cavity of the charging gun. Deformation will occur inside, directly affecting the passage of coolant
