Description

Technical Field

[0002] Cars are an important part of modern civilization. While promoting the rapid development of society, they have also brought increasingly prominent harm to mankind. According to the World Resources Institute and the China Environmental Monitoring Center, seven of the world's ten cities with the most serious air pollution are in my country. The main reason is the pollution of the environment by automobile exhaust. Automobile exhaust not only pollutes the environment, but is also the main source of urban noise. In order to promote the development of ecological civilization, my country vigorously advocates the development of new energy vehicles, among which electric vehicles have developed rapidly in recent years. The function of electric vehicle charging piles is similar to that of gas pumps in gas stations. They can charge various models of electric vehicles according to different voltage levels.

[0003] A large amount of heat is emitted from the interior of a car charging pile when it is in use. Existing heat dissipation outlets of the charging pile mostly dissipate heat by opening heat dissipation holes on the side of the box body. There is a lack of active heat dissipation, and heat is usually dissipated by natural wind, which makes the heat dissipation efficiency poor. Utility Model Content
