Problems solved by technology

As the existing DC charging pile belongs to electric equipment, its heat dissipation and rainproof and dustproof are particularly important. The existing DC charging pile realizes heat dissipation and heat dissipation by opening heat dissipation holes on the protective shell and adding rain shields on the heat dissipation holes. Rainproof, but the setting of the rainshield hinders the flow of hot air, and it is difficult for the rainshield to block the rainwater when the wind and rain are heavy, resulting in that the heat dissipation and rainproof of the DC charging pile cannot be guaranteed
[0003] There are also some technical solutions in the prior art, such as the Chinese patent application number CN201921266101.8, which includes the main body of the charging pile. A first door is installed on one side of the main body of the charging pile, and a winding line device, a second door is installed on one side of the main body of the charging pile, the first door and the second door are opposite to each other, a handle is provided on the first door and the second door, and the upper part of the main body of the charging pile The surface is provided with a first slope, the upper surfaces of the first door body and the second door body are provided with a second slope, the first slope extends downward from left to right, and the drainage groove and the winding device do not coincide in the vertical direction , the upper ends of the main body of the charging pile, the first door, and the second door all adopt a slope design, and the first door and the second door are opposite to the slope of the main body of the charging pile. Water accumulates on the top of the charging pile during use, but when it rains and the wind blows, the rainwater can still enter the charging pile, causing the charging pile to malfunction

Embodiment approach

[0029] As an embodiment of the present invention, a filter screen 33 is fixedly installed in the installation groove 35; the mesh diameter on the filter screen 33 is smaller than the mesh diameter on the primary mesh plate 32; the side wall of the installation groove 35 A reed 34 is fixedly installed on it; the reed 34 is positioned above the filter screen 33; the reed 34 shakes when blown by the air flow; the lower surface of the reed 34 is provided with a hemispherical rubber ball; Slightly tap the filter screen 33 when the reed 34 shakes;

[0030] When working, when the charging pile is working normally, the fan 31 in the installation box 3 continues to run, sucking the outside air into the cabinet 1 to reduce the temperature in the cabinet 1. At the same time, due to the fixed installation in the installation groove 35 There is a filter screen 33, which can further filter the air to prevent dust from entering the cabinet body 1. At the same time, when the air enters the ca...

Abstract

The invention belongs to the technical field of charging piles, and specifically relates to a DC charging pile capable of charging and discharging electric vehicles and performing battery tests. fixed feet; one installation board and two installation boards are installed in the cabinet; electrical components are fixedly installed on the first installation board and the second installation board; an installation box is installed in the cabinet; Fan; the bottom surface of the installation box is provided with a through hole, and the through hole is located directly below the fan; a heat dissipation plate is installed above the installation box; a ventilation cavity is provided in the heat dissipation plate; the ventilation cavity and the installation The box is connected; micropores are opened on the heat dissipation plate; an inner air outlet and an outer air outlet are opened on the inside of the cabinet, and the two are connected; the charging pile of the present invention has a better heat dissipation effect and a better rainproof ability when it rains. Strong, can prevent dust, rain, insects from entering the charging pile, affecting the normal operation of the charging pile.

Description

technical field [0001] The invention belongs to the technical field of charging piles, in particular to a DC charging pile capable of charging and discharging electric vehicles and performing battery tests. Background technique [0002] At present, with the improvement of people's living standards, people pay more and more attention to environmental protection. Energy saving and emission reduction are the most basic environmental protection measures. Therefore, the use of green energy is more and more recognized by people. As a clean and low-carbon green vehicle, electric vehicles have attracted great attention from all over the world. In recent years, with the rapid development of clean energy electric vehicles, users' demand for charging facilities is also increasing. As the existing DC charging pile belongs to electric equipment, its heat dissipation and rainproof and dustproof are particularly important. The existing DC charging pile realizes heat dissipation and heat d...
