The controlled end of the vibration component is connected with the output end of a charging control module in the charging pile, and the vibration component is started according to an output signal of the charging control module to drive the first dust screen 203 and/or the second dust screen 204 to vibrate. The heat generated by the electrical components inside the charging pile main machine housing 209 during operation can be carried out of the charging pile by the cold air entering from the first air opening or the second air opening.

In fig. 2, two maintenance doors are provided with vibration members as an example, for the convenience of distinguishing two vibration members, the vibration member provided on the first maintenance door 201 is defined as a first vibration member 205, the vibration member provided on the second maintenance door 202 is defined as a second vibration member 206, the first vibration member 205 and the second vibration member 206 may be implemented by selecting electric motors, and the driving output ends of the electric motors are attached to the first dust-proof net 203 and the second dust-proof net 204. The electric motor can be realized by selecting a product with a miniaturized structure. For the cooling system, what first wind gap and second wind gap adopted is the shutter structure, therefore wind gap department has many parallel panel beating, and electric motor can be fixed in on the panel beating of wind gap edge also can be fixed in the panel beating in wind gap middle part, generally can fix through locating component such as bolt.

The larger the number of electric motors, the larger the distribution density, the better the vibration effect on the dust screen.

Compared with fig. 2 and fig. 1, in the solution provided in this embodiment, a first cooling fan 207 is disposed on the first maintenance door 201, and the first cooling fan 207 is disposed on an inner side surface of the first dust screen 203; a second heat radiation fan 208 is arranged on the second maintenance door 202, and the second heat radiation fan 208 is arranged on the inner side surface of the second dustproof net 204; controlled ends of the first cooling fan 207 and the second cooling fan 208 are connected with an output end of the charging control module; the first cooling fan 207 and the second cooling fan 208 are started or stopped according to the output signal of the charging control module; through set up cooling fan on two maintenance doors in this scheme, can change the flow direction of air current. Specifically, turning and starting and stopping of the first cooling fan and the second cooling fan enable airflow to flow from the first air opening to the second air opening or from the second air opening to the first air opening. As shown in fig. 2, in the heat dissipation process, a module fan of a rectifier module inside the charging pile and a first heat dissipation fan 207 on the first maintenance door 201 positively rotate to actively suck cold air from the outside of the charging pile and blow the cold air to the high-voltage terminal side of the rectifier module, and a second heat dissipation fan 208 on the second maintenance door 202 positively rotates to discharge hot air out of the charging pile, so that cold air flow sucked into the charging pile and hot air flow discharged out of the charging pile form push-pull air flow. Referring to fig. 4, the first heat dissipation fan 207 on the first maintenance door 201 rotates reversely, and the second heat dissipation fan 208 on the second maintenance door 202 rotates reversely to flow from the second air inlet to the air inlet. Through this scheme, can control the change of air current trend, assume that the air current flows to the second wind gap in-process from first wind gap, when having the dust of leaving over in first dust screen 203, can blow off the dust of leaving over when the air current direction changes to realize better dust removal effect.

As mentioned above, the number of the first heat dissipation fan 207 and the second heat dissipation fan 208 can be determined according to the size and budget of the air door, and the following setting mode can be adopted in the present scheme: the number of the first cooling fans 207 is even (eight in the figure), and the first cooling fans are symmetrically distributed along the central axis of the first dust screen 203; and/or, an even number (eight in the figure) of the second cooling fans 208 are symmetrically distributed along the central axis of the second dust screen 204.

The operation processes of table look-up, comparison and the like can be realized by adopting the existing mature technical scheme. Wherein output signal is used for exporting to vibration part and first cooling fan, second cooling fan, can carry out output signal's setting according to the model of vibration part, first cooling fan and second cooling fan. For example, when the output signal is 011111, the output signal is used to control the vibration component to start, the first cooling fan to rotate forward, and the second cooling fan to rotate forward, and when the output signal is 000101, the output signal is used to control the vibration component to stop, the first cooling fan to rotate backward, and the second cooling fan to rotate backward, and so on, the charging control module 501 in this embodiment can control the start and stop of different components according to the detection result combined with the temperature sensor 502 according to a pre-built data table.

The second correspondence may also be stored in the form of a data table, wherein the detection result of the current sensor 503 is used for detecting whether the charging process is finished. Specifically, the charging control module 501 can determine a charging process according to a detection value of the current sensor 503, and if it is determined that the charging process is finished and the temperature sensor 502 detects that the temperature value inside the charging pile does not reach a safety threshold, the first cooling fan 207 and the second cooling fan 208 can be controlled to rotate forward to realize the operation that the airflow flows from the first air opening to the second air opening, so that the heat dissipation and dust removal work is started. When the temperature sensor 502 detects that the temperature value inside the charging pile reaches the safety threshold value, the first cooling fan 207 and the second cooling fan 208 can be shut down after staying for several seconds, the vibration of the vibration part is started to make accumulated dust on the dust screen vibrate and drop, then the vibration part can be controlled to shut down after staying for several seconds, the first cooling fan 207 rotates reversely, the second cooling fan 208 rotates reversely to realize the operation that the airflow flows from the second air port to the first air port, and therefore the heat dissipation and dust removal work is started. In the above process, the data in the first corresponding relationship and the second corresponding relationship may be set according to actual requirements, and the start time intervals of the vibration component, the first cooling fan and the second cooling fan may also be adjusted, which can be implemented by those skilled in the art according to the above description of the embodiment, and will not be described in detail herein.
