[0003] In the related art, the charging pile includes a heat dissipation structure and electronic components. In some cases, the heat dissipation structure includes a wind-generating component, which is used to generate airflow. When the airflow passes through the electronic components, it can take away heat to achieve the purpose of dissipating the heat of the electronic components. In order to increase the heat dissipation area, the number of wind-generating components is multiple, and adjacent wind-generating components are close to each other.

[0004] However, the charging pile generates heat continuously during operation, and the heat will be transferred to the wind-generating component, causing the temperature of the wind-generating component to be higher. When the airflow flows to the wind-generating component in the middle position, it needs to pass through the wind-generating components in the adjacent positions, causing the temperature of the airflow to be higher when it flows to the wind-generating component in the middle position, thereby causing the heat dissipation effect of the electronic components corresponding to the wind-generating component in the middle position to be poor, which may cause the electronic components to be damaged due to heat accumulation.

[0030] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0031] The following describes in detail a charging pile 100 provided in an embodiment of the present application through a specific embodiment in combination with all the drawings in the specification.

[0032] Please refer to Figure 1 , Figure 2 and Figure 3 In one embodiment of the utility model, a charging pile 100 is disclosed, including a main body 10, a heat dissipation structure 20 and electronic components 30. The main body 10 is provided with an air inlet 101, an installation cavity 102, a heat dissipation cavity 103 and an air outlet 104. The air inlet 101 is connected with the air outlet 104 via the installation cavity 102 and the heat dissipation cavity 103 in sequence; the heat dissipation structure 20 is installed in the installation cavity 102, and the heat dissipation structure 20 is located at the connection between the installation cavity 102 and the heat dissipation cavity 103. The heat dissipation structure 20 includes multiple groups of wind-making components 22, and a first heat dissipation air duct 202 is formed between two adjacent groups of wind-making components 22. A second heat dissipation air duct 204 is formed between a group of wind-making components 22 located on one side of the heat dissipation structure 20 and the side cavity wall of the installation cavity 102; the electronic components 30 are located at the heat dissipation cavity 103.

[0033] Through the above structure, when the wind-generating component 22 is turned on, the airflow passes through the air inlet 101, the installation cavity 102, the heat dissipation cavity 103 and the air outlet 104 in sequence. When the airflow passes through the installation cavity 102, it passes through multiple first heat dissipation ducts 202 and second heat dissipation ducts 204 at the same time. Then, when the volume of the charging pile 100 is fixed, the wind resistance around the wind-generating component 22 in the middle part is smaller, so that a larger volume of airflow can flow through the wind-generating component 22 in the middle part per unit time, so that the low-temperature airflow can flow more evenly through various places in the heat dissipation cavity 103, taking away the heat generated by the electronic components 30, and avoiding overheating and damage of the electronic components 30. Finally, the problem that the heat dissipation effect of some electronic components 30 is poor, which may cause damage to the electronic components 30 due to heat accumulation, is solved.

[0034] Specifically, the electronic components 30 are installed in the main body 10, and a partition plate 12 is provided in the main body 10, which separates the installation cavity 102 from the heat dissipation cavity 103. The heat dissipation structure 20 is installed in the installation cavity 102 and is located at the connection between the partition plate 12 and the heat dissipation cavity 103. In this embodiment, the main body 10 is a structure similar to a rectangular parallelepiped. The installation cavity 102 and the heat dissipation cavity 103 are both located between the air inlet 101 and the air outlet 104. In the direction perpendicular to the horizontal plane, the air inlet 101 and the heat dissipation cavity 103 are staggered from each other, and the air outlet 104 is also staggered from the heat dissipation cavity 103. Optionally, the width of the first heat dissipation duct 202 and the second heat dissipation duct 204 can be the same.

[0035] The number of air inlets 101 and the number of air outlets 104 can both be two, and the installation cavity 102 is a structure similar to a rectangular parallelepiped. In the direction perpendicular to the horizontal plane, the heat dissipation cavity 103 is located in the middle of the installation cavity 102. One air inlet 101 is located at the upper end of the installation cavity 102, and the other air inlet 101 is located at the lower end of the installation cavity 102. One air outlet 104 is located at the upper end of the installation cavity 102, and the other air outlet 104 is located at the lower end of the installation cavity 102. The wind-generating component 22 is a fan, and the electronic component 30 is a power component. The electronic component 30 is installed on the cavity wall of the heat dissipation cavity 103. The electronic component 30 can be located inside the heat dissipation cavity 103 or outside the heat dissipation cavity 103. Sound insulation cotton is pasted on the cavity wall of the installation cavity 102 and the cavity wall of the heat dissipation cavity 103.

[0036] In other embodiments, the main body 10 may also be other structures, connected to the cylinder. The number of the air inlet 101 or the air outlet 104 may also be other, such as one or three. The air inlet 101 may also face the heat dissipation structure 20.

[0037] Please refer to Figure 4In some embodiments, each group of wind-generating components includes multiple wind-generating components 22, all wind-generating components 22 in each group of wind-generating components are arranged in an array, and a third heat dissipation duct 206 is formed between two adjacent wind-generating components 22 in each group of wind-generating components. The third heat dissipation duct 206 is connected to the first heat dissipation duct 202, and the width of the third heat dissipation duct 206 is smaller than the width of the first heat dissipation duct 202, and the width of the third heat dissipation duct 206 is smaller than the width of the second heat dissipation duct 204.

[0038] Through the above structure, the third heat dissipation air duct 206 can allow air to pass through. The third heat dissipation air duct 206 is arranged between each wind-generating component 22 in each group of wind-generating components, and the third heat dissipation air duct 206 is connected to the first heat dissipation air duct 202, and then can quickly flow into the first heat dissipation air duct 202 through the first heat dissipation air duct 202 and contact with the surface of each wind-generating component 22, so that the airflow can flow more evenly between the various wind-generating components 22, and then the heat dissipation effect of the heat dissipation structure 20 on the electronic components 30 is more uniform.

[0039] Specifically, in this embodiment, the heat dissipation structure 20 includes two groups of wind generating components 22, and the two groups of wind generating components 22 are arranged horizontally. Each group of wind generating components includes twelve wind generating components 22, and the twelve wind generating components 22 are arranged in two rows, and the arrangement direction of each row of wind generating components 22 is the vertical direction. In other embodiments, the number of groups of wind generating components 22 can also be other, such as three groups or four groups.

[0040] There are multiple heat dissipation cavities 103, which are arranged in sequence from top to bottom. Two adjacent heat dissipation cavities 103 are separated by a partition 14. A wind-generating component 22 is provided at the connection between each heat dissipation cavity 103 and the installation cavity 102, and the end of each partition 14 is located at the third heat dissipation air duct 206. The partition 14 can be used for the installation of electronic components 30. The air outlet of the wind-generating component 22 is directly opposite to the electronic component 30. Optionally, the electronic component 30 is a power element, and there are multiple power elements, and one power element is installed in each heat dissipation cavity 103. Each power element can correspond to one or more wind-generating components 22, that is, for each power element, one or more wind-generating components 22 can be set to dissipate heat for it. For example, for each power element, two wind-generating components 22 can be set to dissipate heat for it.

[0041] In some embodiments, the air inlet 101 and the heat dissipation structure 20 are respectively located on two sides of the installation cavity 102; in a direction perpendicular to the horizontal plane, the air inlet 101 and the heat dissipation structure 20 are staggered with each other.

[0042] Through the above structure, the air inlet 101 and the heat dissipation structure 20 are staggered, so that the noise generated during the operation of the heat dissipation structure 20 cannot be directly transmitted from the air inlet 101, so that the cavity wall of the installation cavity 102 can soundproof the heat dissipation structure 20.

[0043] Specifically, in the present embodiment, the air inlet 101 is provided at one side of the main body 10 , the air inlet 101 is rectangular, and a noise reduction net 40 is provided at the air inlet 101 .

[0044] In some embodiments, there are two air inlets 101 , one air inlet 101 is located at the upper end of the installation cavity 102 , and the other air inlet 101 is located at the lower end of the installation cavity 102 ; in the direction perpendicular to the horizontal plane, the heat dissipation structure 20 is located in the middle of the installation cavity 102 .

[0045] Through the above structure, in the vertical direction, the heat dissipation structure 20 is located between the two air inlets 101, and in the horizontal direction, the heat dissipation structure 20 and the air inlet 101 are respectively located on both sides of the installation cavity 102. When the heat dissipation structure 20 is turned on, the airflow outside the main body 10 can enter the installation cavity 102 through the two air inlets 101 at the same time, and then the airflow with a lower temperature can flow into the heat dissipation structure 20 through the top and bottom of the heat dissipation structure 20 at the same time, further reducing the possibility of the local temperature of the heat dissipation structure 20 being too high, so that the heat dissipation effect of the heat dissipation structure 20 is more uniform.

[0046] Optionally, the heat dissipation structure 20 may be closer to the air inlet 101 located at the upper end of the main body 10 .

[0047] In some embodiments, the extension direction of the first heat dissipation duct 202 is perpendicular to the extension direction of the heat dissipation cavity 103 , and the two air inlets 101 are arranged in sequence in the extension direction of the first heat dissipation duct 202 .

[0048] Through the above structure, when the airflow flows from the first heat dissipation duct 202 into the heat dissipation cavity 103 , the direction of the airflow changes, and the airflow can be buffered when flowing through the heat dissipation structure 20 to reduce the noise generated when the airflow flows in the main body 10 .

[0049] Specifically, the flow direction of the airflow in the first heat dissipation duct 202 is perpendicular to the flow direction of the airflow in the heat dissipation cavity 103, so that the extension direction of the first heat dissipation duct 202 is perpendicular to the extension direction of the heat dissipation cavity 103. The first heat dissipation duct 202 is a strip structure, the heat dissipation cavity 103 is a rectangular parallelepiped or a cylinder, and the central axis of the heat dissipation cavity 103 is perpendicular to the central axis of the first heat dissipation duct 202.

[0050] In some embodiments, the main body 10 is further provided with a heat conduction cavity 105, and the heat dissipation cavity 103 is connected with the air outlet 104 via the heat conduction cavity 105. The air outlet 104 and the heat dissipation cavity 103 are respectively located on both sides of the heat conduction cavity 105, and the air outlet 104 and the heat dissipation cavity 103 are staggered with each other.

[0051] Through the above structure, the air outlet 104 and the heat dissipation cavity 103 are respectively located on both sides of the heat conduction cavity 105. In the direction perpendicular to the horizontal plane, the air outlet 104 and the heat dissipation cavity 103 are staggered with each other, so that the noise generated during the operation of the heat dissipation structure 20 cannot be directly transmitted from the air outlet 104, so that the cavity wall of the heat conduction cavity 105 plays a sound insulation role for the heat dissipation structure 20.

[0052] Specifically, in this embodiment, the heat conduction cavity 105 has the same structure as the installation cavity 102 . The heat conduction cavity 105 and the installation cavity 102 are symmetrically distributed along the central axis of the main body 10 , and the air outlet 104 is rectangular.

[0053] In some embodiments, there are two air outlets 104, one air outlet 104 is located at the upper end of the heat conduction cavity 105, and the other air outlet 104 is located at the lower end of the heat conduction cavity 105; in the direction perpendicular to the horizontal plane, the connection between the heat dissipation cavity 103 and the heat conduction cavity 105 is located in the middle of the heat dissipation cavity 103.

[0054] Through the above structure, the heat dissipation cavity 103 is located between the two air outlets 104, and the airflow through the heat dissipation cavity 103 can flow out of the main body 10 evenly through the two air outlets 104 at the same time, so that the airflow flowing out of the main body 10 is dispersed, thereby further reducing the noise generated when the airflow flows out of the air outlet 104.

[0055] Specifically, in this embodiment, the air outlet 104 is a rectangular structure, and the air outlet 104 is covered with a noise reduction net 40. In other embodiments, the air outlet 104 can also be other shapes, such as a circle or a polygon, and the air outlet 104 can also be open.

[0056] In some embodiments, the extension direction of the heat dissipation cavity 103 is perpendicular to the extension direction of the heat conduction cavity 105; in the extension direction of the heat dissipation cavity 103, the installation cavity 102, the heat dissipation cavity 103 and the heat conduction cavity 105 are arranged in sequence; in the extension direction of the heat conduction cavity 105, the two air outlets 104 are arranged in sequence.

[0057] Through the above structure, the heat dissipation cavity 103 extends in the horizontal direction, and the heat conduction cavity 105 extends in the vertical direction. When the airflow passes through the connection between the heat dissipation cavity 103 and the heat conduction cavity 105, the flow direction of the airflow changes by 90° and splits, and the two airflows after splitting flow in opposite directions, and the two air outlets 104 are far away from the heat dissipation cavity 103. The heat conduction cavity 105 guides and buffers the airflow, so that the noise is small when the airflow flows out of the air outlet 104.

[0058] Specifically, the heat conduction cavity 105 and the installation cavity 102 are respectively located on both sides of the main body 10, and the heat dissipation cavity 103 is located between the installation cavity 102 and the heat conduction cavity 105, one end of the heat dissipation cavity 103 is connected to the installation cavity 102, and the other end of the heat dissipation cavity 103 is connected to the heat conduction cavity 105, so that the installation cavity 102, the heat dissipation cavity 103 and the heat conduction cavity 105 are arranged in sequence. One air outlet 104 is located at the upper end of the heat conduction cavity 105, and the other air outlet 104 is located at the lower end of the heat conduction cavity 105, and the air outlet 104 and the heat dissipation cavity 103 are respectively connected to the two sides of the heat conduction cavity 105.

[0059] In some embodiments, the air outlets 104 correspond to the air inlets 101 one by one, and the air inlets 101 and the corresponding air outlets 104 are located at the same height.

[0060] Through the above structure, the air inlet 101 and the air outlet 104 located at the upper end of the main body 10 are located at the same height, and the air inlet 101 and the air outlet 104 located at the lower end of the main body 10 are also located at the same height, so that the airflow can have a longer flow path in the main body 10, and the airflow can have a better heat dissipation effect on the electronic components 30 in the main body 10.

[0061] Specifically, the air inlet 101 and the air outlet 104 have the same size, so that during the manufacturing process of the main body 10, the air inlet 101 and the air outlet 104 can be opened with the same type of production equipment.

[0062] Please refer to Figure 5 In some embodiments, the charging pile 100 further includes a noise reduction net 40 , which is installed on the main body 10 , and covers the air inlet 101 and the air outlet 104 , and has a plurality of mesh holes 402 .

[0063] Through the above structure, the noise reduction net 40 at the air inlet 101 and the air outlet 104 can further prevent the noise generated by the heat dissipation structure 20 from being transmitted out of the main body 10. There can be a smaller gap between two adjacent mesh holes 402, so that the noise reduction net 40 with mesh holes 402 has less obstruction to the airflow.

[0064] Specifically, the noise reduction net 40 is detachably connected to the main body 10 by screws, and the inner surface of the noise reduction net 40 can be pasted with sound insulation cotton. In this embodiment, the mesh 402 is a hexagonal through hole. In other embodiments, the mesh 402 can also be other shapes, such as a rectangle or a parallelogram.

[0065] In other embodiments, the meshes of the noise reduction net 40 may also be in other shapes, such as diamond, rectangle or circle. The noise reduction net 40 may also be in other structures, such as a structure similar to a shutter.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Under the idea of ​​the present invention, the technical features in the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other changes in different aspects of the present invention as described above, which are not provided in detail for the sake of simplicity. Although the present invention is described in detail with reference to the aforementioned embodiments, a person of ordinary skill in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features can be replaced by equivalents. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
