Charging pile capable of rapidly dissipating heat

Abstract

The invention relates to the technical field of new energy vehicles, and discloses a rapid heat dissipation charging pile which comprises a charging pile body, a charging head, a first air bag, a partition plate and a second air bag. A magnetic ring is fixedly connected to the outer side of the joint of the charging head and the charging pile body. By designing the first air bag, the second air bag, the through pipe, the check block, the spring, the sliding block, the air outlet pipe and the air return pipe, air in the first air bag is expanded and released through the air outlet pipe due to internal heating when the charging pile works, and the air pressure is smaller than that in the second air bag after the air in the first air bag is released; compressed air in the second air bag enters the first air bag through the air return pipe, the compressed air is released and absorbs the temperature of the compressed air through the heat conducting piece in the air return pipe when passing through the air return pipe, the air entering the first air bag is low-temperature air, and cooling of the interior of the charging pile is achieved through heat absorption of the low-temperature air; and the internal temperature of the charging pile during use is prevented from being too high.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a fast heat dissipation charging pile. Background technique [0002] With the requirement of energy saving and environmental protection, new energy vehicles are welcomed by more and more people. The main power source of new energy vehicles is electric energy, and charging piles are an indispensable supporting facility for new energy vehicles. [0003] The input end of the new energy vehicle charging pile is directly connected to the AC power grid, and the output end is equipped with a charging plug to charge the electric vehicle. Due to the high power of the charging pile during operation, the temperature inside the box can basically reach above 150 degrees Celsius. It is easy to accelerate the aging and damage of the internal components of the box, insufficient charging or even burn the electronic components, etc., shortening the service life of the charging pile. ...
