Automobiles are a vehicle with an increasing popularity. The operation of the automobile can not be realized by gasoline, the emission of automobile exhaust causes global warming, environment deterioration and serious influence on various aspects of the environment, meanwhile, the gasoline is used as a non-renewable energy source, the automobile resource is increasingly exhausted, and the point has to be paid attention to by human beings. New environmentally-friendly renewable energy sources become the main body of the future market, so that electric vehicles are a new lead for future development. The electric automobile is used as a power source through charging, the electric energy consumption is high, the driving mileage can be ensured only by ensuring full charge in the charging process, and the electric automobile is prevented from being incapable of driving due to energy shortage midway. Most of the existing electric automobiles meet the charging requirement of the electric automobiles through charging guns, and the charging guns play the role of the electric automobiles and bridges connected with charging piles.
Electric automobile need use bigger and bigger charging current, and the heavy current can produce the temperature rise, and the temperature rise can lead to electric automobile's socket end that charges to give out heat big, has the potential safety hazard. The usual methods for reducing the temperature rise are: the cross-sectional area of the copper conductor of the cable is increased. However, this approach makes the cable too bulky and less flexible. Patent CN106104949A discloses a charging cable comprising a charging conductor and a cooling conduit arranged independently inside the outer sheath of the charging cable. However, the charging conductor and the cooling duct of this patent are provided separately, and the cooling duct cannot sufficiently dissipate heat of the charging conductor, resulting in poor heat dissipation of the charging cable.
Therefore, how to solve the important problem that the heat dissipation of the battery is to ensure the quick charging and the safe charging.
