Problems solved by technology

The problem that comes with it is: due to the excessive current, the terminal at the charging socket heats up seriously, resulting in burning of the charging terminal or charging failure, so that the whole vehicle cannot be charged normally, and the charging safety cannot be effectively guaranteed
[0004] In addition, although some manufacturers are currently actively adopting some methods to reduce the temperature at the terminal, for example, arranging cooling devices at the charging harness, but the cooling effect is not ideal, and the arrangement is more complicated

Abstract

The invention discloses a heat sink of a charging connection piece, a charging device, a vehicle and a charging gun. The heat sink comprises a body and a cold air pipeline, wherein an accommodating groove is formed in the body and is used for accommodating the charging connection piece, a cooling chamber is arranged at an outer side of the accommodating groove, and the cold air pipeline is arranged on the body and is used for sending air to the charging connection piece. After the charging connection piece is arranged in the heat sink, the heat sink can employ forms of water cooling, air cooling and natural cooling to cool the charging connection piece, so that the working temperature of the charging connection piece can be effectively controlled, the problem of overheat of a wiring terminal can be prevented, and the charging safety of the vehicle can be ensured. Moreover, the charging device can be used for large-power charging.

Description

technical field [0001] The invention relates to the technical field of vehicle charging, in particular to a radiator for a charging connector, a charging device with the radiator, a vehicle and a charging gun with the charging device. Background technique [0002] At present, due to energy and environmental issues, the explosive growth of new energy vehicles has been promoted, and the number of new energy vehicles has also continued to rise. Compared with traditional fuel vehicles, new energy vehicles have great advantages in energy saving and environmental protection, but the long charging time of electric vehicles has been criticized for a long time. [0003] At this stage, the method of shortening the charging time by increasing the charging power is generally adopted. The problem that comes with it is: due to the excessive current, the terminal at the charging socket heats up severely, resulting in burning of the charging terminal or charging failure, so that the whole ...
