  • the liquid cold terminal of the charging gun is shaft-shaped, one end is a closed plug end corresponding to the charging socket of the electric vehicle, and the other end is an opening corresponding to the soft wire of the high-power charging pile liquid cooling cable.
  • a protruding positioning member for connecting with the charging gun body is provided in the middle of the outer diameter of the liquid cooling terminal of the charging gun, and the outer diameter of the liquid cooling terminal of the charging gun
  • a protruding through hole communicating with the cooling cavity is disposed between the positioning member and the opening end of the opening, and the two through holes on the two liquid cooling cables of the positive electrode and the negative electrode are communicated through the insulating connecting pipe assembly.
  • the cooling cavities of the liquid-cooling terminals of the two charging guns on the two liquid-cooled cables of the positive and negative electrodes are respectively equipped with a fluid separation body, and the cooling cavity is a cylindrical cavity.
  • the fluid to be described is a circular shaft shape, and a notch sinking table and a sinking table are arranged on both sides of the outer cylindrical surface of the shaft and the axial plane of the shaft, and one of the axial end faces is provided with a connecting sinking groove, and the fluid dividing body has a connecting sinking groove.
  • the cooling liquid can be: non-conductive liquid medium such as pure water, transformer oil, transformer silicone oil, fluorinated liquid. Since the positive electrode and the negative electrode are cooled in series, the coolant flows between the positive electrode and the negative electrode, and therefore, the coolant must be a non-conductive liquid medium. Pure water can be used in the normal temperature zone, and cooling oil can be used in the cold zone to prevent the cooling medium from freezing and ensure the normal operation of the cable in different zones.

Abstract

La présente invention porte sur une structure de refroidissement en série de câbles de refroidissement de liquide positif et négatif d'une pile de charge haute puissance, comprenant une enveloppe externe d'isolation de câbles de refroidissement de liquide, ainsi qu'un fil PE et une pluralité de fils de transmission qui sont disposés dans l'enveloppe externe d'isolation de câbles de refroidissement de liquide. Un câble de refroidissement de liquide positif et un câble de refroidissement de liquide négatif sont également disposés dans l'enveloppe externe d'isolation de câbles de refroidissement de liquide, chaque câble étant constitué d'un fil conducteur souple et d'un corps d'isolation, le fil conducteur souple étant placé dans le corps d'isolation, et l'espace prévu entre le fil conducteur souple et le corps d'isolation étant un passage de liquide de refroidissement. Une extrémité du fil conducteur souple est raccordée à une borne de refroidissement de liquide d'un pistolet de charge, et l'autre extrémité du fil conducteur souple est raccordée à une électrode de câble de refroidissement de liquide, et l'électrode de câble de refroidissement de liquide est dotée d'un tuyau d'électrode qui est en communication avec le passage de liquide de refroidissement. Chacune des bornes de refroidissement de liquide des deux pistolets de charge est comporte une cavité de refroidissement qui est en communication avec le passage de fluide de refroidissement correspondant, les deux cavités de refroidissement étant en communication l'une avec l'autre au moyen d'un ensemble tuyau de raccordement d'isolation. La présente invention permet d'acheminer en toute sécurité un courant important et d'éviter une surchauffe des câbles pendant l'opération de charge.
