Description

Technical Field

[0001] The utility model relates to the field of new energy equipment, in particular to a charging pile. Background Art

[0002] At present, new energy vehicles are more environmentally friendly than ordinary vehicles, and new energy vehicles are gradually entering people's lives. Charging piles are an electrical integrated device used to charge new energy vehicles.

[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, and the heat dissipation structure is provided with an air inlet and an air outlet; the wind-generating component is used to generate airflow, which flows to the electronic components through the air inlet and takes away the heat in the electronic components to achieve the purpose of dissipating heat from the electronic components. In order to prevent the airflow from driving debris into the heat dissipation structure, such as dust or mosquitoes, a dust-proof component is generally provided at the air inlet.

[0004] However, the wind resistance of the dustproof component is relatively large, and the velocity of the external airflow will be reduced when flowing through the dustproof component, resulting in a lower velocity of the airflow flowing through the electronic components, which in turn leads to poor heat dissipation effect of the heat dissipation structure on the electronic components.

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.

[0036] 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.

[0037] Please refer to Figure 1 , Figure 2 and Figure 3In one embodiment of the utility model, a charging pile 100 is disclosed, including a main body 10, a first dust-proof component 20, a wind-making component 30 and electronic components 40; the main body 10 is provided with a first air inlet 101, a second air inlet 102, an installation cavity 103, a heat dissipation cavity 104 and an air outlet 105, the area of ​​the second air inlet 102 is larger than that of the first air inlet 101, and the first air inlet 101 is connected with the air outlet 105 via the second air inlet 102, the installation cavity 103 and the heat dissipation cavity 104 in sequence; the first dust-proof component 20 is installed at the second air inlet 102; the wind-making component 30 is installed in the installation cavity 103; the electronic components 40 are located at the heat dissipation cavity 104. Figure 3 The direction of the dashed arrow is the flow direction of the airflow in the main body 10 .

[0038] Through the above structure, when the electronic components 40 in the main body 10 are working, the wind-generating component 30 in the installation cavity 103 will also be opened, so that the low-temperature airflow from the outside flows into the heat dissipation cavity 104 through the first air inlet 101, the second air inlet 102 and the installation cavity 103 in sequence, and the low-temperature airflow contacts the electronic components 40 in the heat dissipation cavity 104 and takes away the heat, and then the gas flows out of the main body 10 through the air outlet 105 with the heat, and then the wind-generating component 30 can have a heat dissipation effect on the electronic components 40.

[0039] In addition, the first dust-proof component 20 is made of a material with a finer mesh, so that the wind resistance of the first dust-proof component 20 is larger; the area of ​​the first air inlet 101 is small, and the first dust-proof component 20 is not installed at the first air inlet 101, so that the wind resistance per unit area of ​​the first air inlet 101 is smaller, and thus the total wind resistance of the first air inlet 101 is smaller; the first dust-proof component 20 is installed at the second air inlet 102, and the wind resistance per unit area of ​​the second air inlet 102 is larger, but the area of ​​the second air inlet 102 is larger, and the overall wind resistance of the second air inlet 102 is smaller, and the flow rate of external gas flowing into the first air inlet 101 and the second air inlet 102 is faster; the overall wind resistance of the main body 10 is reduced, thereby improving the heat dissipation effect of the wind-generating component 30 on the electronic components 40. At the same time, the first dust-proof component 20 at the second air inlet 102 can prevent foreign matter from entering the installation cavity 103.

[0040] Specifically, in this embodiment, the main body 10 is a hollow structure similar to a rectangular parallelepiped, and the first air inlet 101 and the second air inlet 102 can both be rectangular; and the direction of the airflow through the first air inlet 101 is perpendicular to the direction of the airflow through the second air inlet 102. The wind-generating component 30 can be a fan driven by a motor, and the heat dissipation cavity 104 is a structure similar to a rectangular parallelepiped. The heat dissipation cavity 104 is located on the upper side of the main body 10. The wind-generating component 30 is installed at the connection between the installation cavity 103 and the heat dissipation cavity 104, and each heat dissipation cavity 104 corresponds to a plurality of wind-generating components 30. The electronic components 40 can be a circuit board and capacitors, resistors, transistors, etc. installed on the circuit board. The electronic components 40 are installed on the cavity wall of the heat dissipation cavity 104.

[0041] In other embodiments, the main body 10 may also be other structures, such as a cylinder; the first air inlet 101 and the second air inlet 102 may also be other shapes, such as a circle; the heat dissipation cavity 104 may also be other structures, such as a cylinder; the heat dissipation cavity 104 may also be located at other positions of the main body 10, such as the middle or lower part.

[0042] In some embodiments, the main body 10 is also provided with a first fluid channel 106 and a second fluid channel 107 arranged in parallel; the first air inlet 101 is connected to the installation cavity 103 via the first fluid channel 106, the second air inlet 102 and the second fluid channel 107 in sequence, and the direction of the airflow through the first fluid channel 106 is opposite to the direction of the airflow through the second fluid channel 107.

[0043] Through the above structure, the direction of the airflow when flowing through the first fluid channel 106 is opposite to the direction of the airflow when flowing through the second fluid channel 107, so that the airflow can have a longer flow channel before flowing into the installation cavity 103, and then the airflow can flow into the heat dissipation cavity 104 more evenly through the installation cavity 103, so that the airflow can have a better heat dissipation effect on the electronic components 40.

[0044] In addition, the noise generated during the operation of the wind-generating component 30 needs to pass through the installation cavity 103, the second fluid channel 107 and the first fluid channel 106 in sequence and then be transmitted out of the first air inlet 101. As a result, the flow path of the noise in the process of being transmitted out of the main body 10 is longer, so that the noise will be weakened to a greater extent in the process of being transmitted out of the main body 10, so that the main body 10 has a better sound insulation effect.

[0045] Specifically, in the present embodiment, the first fluid channel 106, the second fluid channel 107 and the installation cavity 103 can all be in a structure similar to a rectangular parallelepiped, the first air inlet 101 is located on one side of the first fluid channel 106, and the second air inlet 102 is opened at the side wall of the first fluid channel 106 with the largest area, so that the area of ​​the second air inlet 102 can be larger than the area of ​​the first air inlet 101, and the first fluid channel 106 is connected to the second fluid channel 107 through the second air inlet 102; the long side of the installation cavity 103 is perpendicular to the long side of the first fluid channel 106.

[0046] In other embodiments, the first fluid channel 106 , the second fluid channel 107 and the mounting cavity 103 may also be other structures, such as a cylinder.

[0047] In some embodiments, the installation cavity 103 is located on one side of the heat dissipation cavity 104 , and the second fluid channel 107 is located on the other adjacent side of the heat dissipation cavity 104 ; the heat dissipation cavity 104 is located on one side of the second fluid channel 107 , and the second air inlet 102 is located on the other opposite side of the second fluid channel 107 .

[0048] Through the above structure, the structure of the entire main body 10 is more compact, so that the volume of the main body 10 is as small as possible; at the same time, the airflow flows through the first fluid channel 106, the second fluid channel 107 and the installation cavity 103 in sequence before flowing into the heat dissipation cavity 104, so that the airflow has a longer flow path in the main body 10, so that the noise generated at the wind-generating component 30 is difficult to be transmitted out of the main body 10.

[0049] Specifically, the main body 10 is formed by enclosing a sheet metal material, and sheet metal can be disposed between the first fluid channel 106 and the second fluid channel 107 , between the second fluid channel 107 and the heat dissipation cavity 104 , and between the heat dissipation cavity 104 and the installation cavity 103 .

[0050] In some embodiments, the second air inlet 102 is located on one side of the first fluid channel 106, and the first air inlet 101 is located on the other adjacent side of the first fluid channel 106; in the vertical direction, the heat dissipation cavity 104, the second fluid channel 107, the second air inlet 102 and the first fluid channel 106 are arranged in sequence; in the horizontal direction, the first air inlet 101, the installation cavity 103 and the heat dissipation cavity 104 are arranged in sequence; the first air inlet 101 and the heat dissipation cavity 104 are staggered with each other.

[0051] Through the above structure, the first air inlet 101 and the second air inlet 102 are respectively located on the adjacent two sides of the first fluid channel 106, and the areas of the adjacent two sides of the first fluid channel 106 are different, so that when the area of ​​the second air inlet 102 is larger than the area of ​​the second air inlet 102, the area of ​​the first air inlet 101 and the area of ​​the second air inlet 102 are as large as possible to increase the rate at which the external air flow flows into the main body 10.

[0052] In addition, the first air inlet 101 and the heat dissipation cavity 104 are staggered with each other, so that the noise generated at the wind-generating component 30 is difficult to be transmitted to the first air inlet 101 in a straight line. In the process of the noise being transmitted out of the main body 10, it will contact the cavity wall of the installation cavity 103, the side wall of the first fluid channel 106, and the side wall of the second fluid channel 107, so that the noise is reduced.

[0053] Specifically, the heat dissipation cavity 104 is located at the upper part of the main body 10, and the first air inlet 101 is located at the lower part of one side of the main body 10; and the first air inlet 101 is located on one side of the installation cavity 103, and the heat dissipation cavity 104 is located on the other opposite side of the installation cavity 103, so that the first air inlet 101 and the heat dissipation cavity 104 are staggered with each other.

[0054] Please refer to Figure 4 In some embodiments, the charging pile 100 further includes a first waterproof component 50, and the first waterproof component 50 is installed at the first air inlet 101; the first air inlet 101 is a mesh structure.

[0055] Through the above structure, the first waterproof component 50 can prevent water droplets from entering the main body 10 to prevent water droplets from contacting dust at the first dustproof component 20, thereby preventing the second air inlet 102 from being blocked by wet dust. The mesh structure at the first air inlet 101 facilitates the installation of the first waterproof component 50.

[0056] Specifically, in this embodiment, the first waterproof component 50 can be a strip-shaped sponge structure, and the first waterproof component 50 can be attached to the first air inlet 101; the mesh at the first air inlet 101 is hexagonal. In other embodiments, the first waterproof component 50 can also be other structures, such as activated carbon; the mesh at the first air inlet 101 can also be other shapes, such as rectangle or diamond.

[0057] Please also read Figure 3 and Figure 5 In some embodiments, the main body 10 is further provided with an air outlet cavity 108, and the heat dissipation cavity 104 is connected with the air outlet 105 via the air outlet cavity 108; the heat dissipation cavity 104 is located on one side of the air outlet cavity 108, and the air outlet 105 is located on the other opposite side of the air outlet cavity 108; in the horizontal direction, the air outlet 105 and the heat dissipation cavity 104 are staggered with each other.

[0058] Through the above structure, a heat dissipation cavity 104 and an air outlet cavity 108 are provided between the wind-generating component 30 and the air outlet 105, and in the horizontal direction, the air outlet 105 and the heat dissipation cavity 104 are staggered with each other; therefore, in the process of the noise generated at the wind-generating component 30 being transmitted to the air outlet 105, it needs to pass through the heat dissipation cavity 104 and the air outlet cavity 108 in sequence, and the cavity walls of the heat dissipation cavity 104 and the air outlet cavity 108 can block the noise, so as to reduce the noise transmitted from the air outlet 105.

[0059] Specifically, the heat dissipation cavity 104 is located at the upper part of the main body 10, and the air outlet 105 is located at the lower part of one side of the main body 10, so that the air outlet 105 and the heat dissipation cavity 104 are staggered in the horizontal direction. In this embodiment, the air outlet 105 can be a rectangular structure; in other embodiments, the air outlet 105 can also be other shapes, such as a circle or a hexagon.

[0060] In some embodiments, the charging pile 100 also includes a partition 60, which is connected to the cavity wall of the air outlet cavity 108 on the side away from the heat dissipation cavity 104. The partition 60 is located in the air outlet cavity 108. The partition 60 divides the air outlet cavity 108 into a first chamber 1082 and a second chamber 1084 that are interconnected. The heat dissipation cavity 104 is connected to the air outlet 105 via the first chamber 1082 and the second chamber 1084 in turn.

[0061] Through the above structure, the partition 60 can further block the noise generated by the wind-generating component 30, so that the noise in the main body 10 is further weakened.

[0062] Specifically, in this embodiment, in the vertical direction, the first chamber 1082 and the second chamber 1084 are arranged in sequence. The partition 60 is composed of two mutually perpendicular sheet metals, one side of the partition 60 is connected to a side cavity wall of the air outlet cavity 108, and the two ends of the partition 60 are respectively connected to the other two opposite side cavity walls of the air outlet cavity 108.

[0063] In other embodiments, the first chamber 1082 and the second chamber 1084 may also be arranged from left to right; the partition 60 may also be other structures, such as an arc-shaped sheet structure or a wavy sheet metal structure. In addition, the partition 60 may also prevent debris at the air outlet 105 from flowing from the air outlet 105 to the heat dissipation chamber 104.

[0064] In some embodiments, the partition 60 includes a first bending section 62 and a second bending section 64 which are perpendicular to each other, one side of the first bending section 62 is connected to the cavity wall of the air outlet cavity 108 which is away from the heat dissipation cavity 104, and the other side of the first bending section 62 is connected to the second bending section 64; the first bending section 62 and the second bending section 64 surround to form a second chamber 1084, and there is a gap between the side of the second bending section 64 which is away from the first bending section 62 and the cavity wall of the air outlet cavity 108, and the first chamber 1082 is connected to the second chamber 1084 via the gap between the second bending section 64 and the cavity wall of the air outlet cavity 108.

[0065] Through the above structure, the mutually perpendicular first bending section 62 and second bending section 64 can prevent foreign matter from flowing into the heat dissipation cavity 104 from two mutually perpendicular directions, further avoiding the possibility of foreign matter entering the heat dissipation cavity 104 and contaminating the electronic components 40 .

[0066] In addition, both the first bending section 62 and the second bending section 64 can guide the airflow in the air outlet cavity 108 so that the airflow has a longer flow path in the air outlet cavity 108 , thereby further reducing the noise in the main body 10 .

[0067] Specifically, in this embodiment, the first bending section 62 and the second bending section 64 can both be rectangular sheet structures; in the horizontal direction, the projection of the second bending section 64 partially overlaps with the projection of the air outlet 105. The upper side of the second bending section 64 is connected to the first bending section 62, and there is a gap between the lower side of the second bending section 64 and the bottom cavity wall of the air outlet cavity 108.

[0068] In other embodiments, the first bending section 62 and the second bending section 64 may be other structures, such as an arc-shaped sheet structure.

[0069] In some embodiments, the charging pile 100 further includes a second dustproof component 70 and a second waterproof component 80 , and the second dustproof component 70 and the second waterproof component 80 are both installed at the air outlet 105 .

[0070] Through the above structure, the second dustproof component 70 can also prevent fine particles or dust from entering the heat dissipation cavity 104, thereby preventing fine particles or dust from entering the heat dissipation cavity 104 and contacting the electronic components 40; the second waterproof component 80 can prevent water droplets from entering the main body 10 to prevent water droplets from entering the air outlet cavity 108, thereby preventing water droplets from entering the heat dissipation cavity 104 and contacting the electronic components 40.

[0071] Specifically, the second dustproof component 70 has the same structure as the first dustproof component 20, both of which are rectangular sheet structures. The second waterproof component 80 can be made of sponge or other water-absorbing materials, such as activated carbon.

[0072] In some embodiments, the number of the heat dissipation cavities 104 is at least two, all the heat dissipation cavities 104 are arranged in parallel, and each heat dissipation cavity 104 corresponds to a group of wind-generating components 30 .

[0073] Through the above structure, each heat dissipation cavity 104 can be used to install electronic components 40, and multiple heat dissipation cavities 104 are arranged in parallel, so that more electronic components 40 can be installed in the main body 10. And the airflow generated by each group of wind-generating components 30 can flow into the corresponding heat dissipation cavity 104, so that the airflow can flow into each heat dissipation cavity 104 more evenly.

[0074] Specifically, in this embodiment, the number of heat dissipation cavities 104 is two, and the two heat dissipation cavities 104 are arranged sequentially from top to bottom, that is, in the vertical direction, the two heat dissipation cavities 104 are arranged side by side. In other embodiments, the number of heat dissipation cavities 104 can also be other, such as three or four; the heat dissipation cavities 104 can also be arranged in other ways, such as the heat dissipation cavities 104 are arranged sequentially in the horizontal direction.
