[0002] In order to shorten the charging time of new energy vehicles, more and more car companies use high-voltage and high-current methods for high-power charging, which brings about the consequences of excessive heat accumulation and poor heat dissipation in the charging gun head and charging cable. , seriously restricting the development of car charging in the direction of safety and efficiency

[0003] Chinese patent application CN208589277U proposes a cable for a high-power charging gun with a cooling function. By arranging a cooling pipe inside the cable and further connecting a circulating cooler to form a cooling circuit, the distance of the cooling circuit in the cable is very long, resulting in cooling The temperature of the liquid continues to rise, which limits the heat that the coolant can take away and the heat dissipation of the cables is uneven

Chinese patent application CN207416561U proposes a charging gun with heat dissipation function. Cooling flow passages and cooling pipes are arranged in the charging gun, and the heat inside the charging gun can be dissipated rapidly through the continuously flowing cooling medium, but it does not enter the charging gun. Further cooling is done before the terminal to improve the heat dissipation effect of the terminal, and there is no further cooling when the coolant flows out of the terminal, which causes the temperature of the coolant to flow back into the cable to be too high, which has a great impact on the heat dissipation of the cable, and the above-mentioned patent scheme lacks simplicity.
