Abstract

The invention discloses a high-power charging connector cooling device for a new energy automobile. The high-power charging connector cooling device comprises a cable, a cooling fin, a thermoelectricrefrigeration sheet, a refrigeration disc, a cooling inner pipe, an outer pipe and a terminal cooling disc; the cooling inner pipe is designed in the cable, penetrates through the refrigeration disc and then is connected with the terminal cooling disc in a sealed mode, a hollow flow channel is formed in the terminal cooling disc, and a leakage detection sensor is arranged between the terminal cooling disc and the refrigeration disc; a thermoelectric refrigeration sheet and a cooling fin are bonded to the upper surface of the refrigeration disc to fully refrigerate the cooling liquid; and the cooling device has the advantages of the high heat dissipation speed, leakage pollution prevention and convenient leakage detection.

Description

technical field [0001] The invention relates to the field of new energy vehicles, in particular to a high-power charging connector cooling device for new energy vehicles. Background technique [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 t...
