[0031] In this embodiment, the ventilation device 2 is arranged on the side of the charger body 1 equipped with the heating element 101, and the side walls of the two are directly connected. The charger body 1 is cooled by the ventilation device 2, which can effectively reduce the overall volume of the charger, thereby facilitating carrying.
[0032] According to an embodiment provided by the utility model, Figure 1 and Figure 2 As shown, the ventilation device 2 includes an air inlet assembly and an air exhaust assembly. The ventilation device 2 is provided with air inlet assemblies on both sides adjacent to the charger body 1, and the ventilation device 2 is provided with an air exhaust assembly on the side opposite to the charger body 1.
[0033] In the present embodiment, further, the ventilation device 2 includes an air inlet assembly and an air exhaust assembly. Preferably, air inlet assemblies are installed on both sides of the ventilation device 2 adjacent to the charger body 1, and an exhaust assembly is installed on the side wall between the two groups of air inlet assemblies. The charger body 1 includes a circuit board area, which dissipates heat during operation. The air inlet assemblies on both sides of the ventilation device 2 connected thereto simultaneously pass gas into it, and the gas is extracted through the exhaust assembly in the middle to dissipate heat.
[0034] By installing the exhaust assembly in the middle position and letting in gas through the air inlet assemblies on both sides at the same time, the volume can be effectively reduced to a certain extent, so that the overall volume of the electric vehicle charger provided by this embodiment is reduced and can be easily carried.
[0035] According to an embodiment provided by the utility model, Figure 1 and Figure 2 As shown, the interior of the ventilation device 2 is hollow and is used for passing gas in or out, and a receiving cavity is formed therein for receiving the passed gas.
[0036] In this embodiment, the interior of the ventilation device 2 is set as a hollow structure, and a accommodating cavity is formed inside to accommodate the gas introduced, so that it is convenient for the air inlet components installed on both sides to allow the gas to pass in, and it is also convenient for the exhaust components to discharge the gas from the inside. Since the interior is set as a hollow structure, the gas can effectively absorb and discharge heat therein, which can effectively increase the heat dissipation effect of the ventilation device 2.
[0037] According to an embodiment provided by the utility model, Figure 3 As shown, the ventilation device 2 further includes a heat sink 201 , and the heat sink 201 is arranged on a side wall where the ventilation device 2 is connected to the charger body 1 .
[0038] In this embodiment, in order to ensure the heat dissipation effect of the ventilation device 2, the ventilation device 2 is also provided with a heat sink 201, and the heat sink 201 is installed on the side wall connecting the ventilation device 2 and the charger body 1, so that the heat sink 201 can dissipate the heat generated by the heating element 101.
[0039] The heat sink is in full contact with the gas inside the accommodating cavity, and then the gas with increased temperature is extracted through the exhaust component, thereby achieving the heat dissipation effect.
[0040] According to an embodiment provided by the utility model, Figure 3 As shown, a plurality of heat sinks 201 are provided and are spaced apart and distributed on the side wall of the ventilation device 2 from top to bottom.

The through slots 202 on both sides are connected through the accommodating cavity inside the ventilation device 2 to form an air duct for the introduction of gas. The gas is introduced into the accommodating cavity inside the ventilation device 2. After the gas enters the air duct from the through slots 202 and fully contacts with the heat sink 201, it is extracted by the exhaust component, thereby taking away the heat and achieving the heat dissipation effect.
[0046] According to an embodiment provided by the utility model, Figure 1 and Figure 2 As shown, the exhaust assembly includes a fan 203, which is arranged on the side wall of the ventilation device 2 and is used to exhaust the heated gas in the accommodating cavity.

The gas fully contacts the heat sink 201 through the air duct, takes away the heat, and is then extracted through the fan 203. The double-sided air intake can not only reduce the total volume of the air duct, but also enhance the heat dissipation effect, thereby increasing the safety of use and the heat dissipation efficiency of the electric vehicle charger provided in this embodiment.
[0048] Among them, optionally, the number of fans 203 is set to one, which is installed on the corresponding side wall in the middle of the air duct. The number of fans 203 can be increased according to actual usage. Its purpose does not deviate from the design concept of the utility model and should belong to the protection scope of the utility model.
[0049] According to an embodiment provided by the utility model, Figure 1 and Figure 2 As shown, the fan 203 is electrically connected to the charger body 1 .

[0051] Among them, optionally, the fan 203 can also be provided with its own independent power supply, and a fan 203 switch can be installed for control, and its purpose does not deviate from the design concept of the utility model and should belong to the protection scope of the utility model.
[0052] According to an embodiment provided by the utility model, Figure 1 As shown, the charger body 1 includes a plug assembly, which is used to connect the power source, the charger body 1 and the charging port of the electric vehicle.
