Description

Technical Field

[0001] This application relates to the field of vehicle battery swapping technology, and more specifically, to a charging pile. Background Technology

[0002] In recent years, with the popularization of electric vehicles, the supporting charging and battery swapping infrastructure has developed rapidly. DC fast charging, due to its high power and short charging time, can effectively alleviate range anxiety and has become the main development direction. Currently, increasing charging power and charging current are the industry's focus, but it still faces technical bottlenecks such as the development of high-rated current devices and heat dissipation and noise control in limited spaces.

[0003] Most known air-cooled charging piles adopt a direct ventilation cabinet structure with IP54 protection level. The fan is located at the air inlet and outlet. When the charging pile has high output power, the noise of the high-speed fan at the air inlet and outlet will be directly transmitted to the surrounding environment.

Detailed Implementation

[0019] It is readily understood that, based on the technical solution of this application, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this application. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this application and should not be considered as the entirety of this application or as limitations or restrictions on the technical solution of this application.

[0020] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly used in this specification are defined relative to the structures shown in the accompanying drawings. These are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive. Furthermore, the terms "first," "second," "third," and similar expressions are used for descriptive and distinguishing purposes only and should not be construed as indicating or implying the relative importance of the corresponding components or the order of components or assembly sequence.

[0021] refer to Figure 1 and 2, which shows an overall schematic structural view and a side view of a charging pile 10 proposed according to an embodiment of the present application, wherein arrows in the figures show a flow direction of cooling air. The charging pile 10 comprises a cabinet body 100, a charging module 200 and a fan 300 arranged in the cabinet body 100. The cabinet body 100 is particularly a hexahedral cabinet, for example, a rectangular parallelepiped cabinet, and has four side surfaces. An air duct 400 is arranged in the cabinet body, an air inlet 401 and an air outlet 402 of the air duct 400 are respectively arranged on two side surfaces of the cabinet body 100, particularly arranged on two opposite side surfaces of the cabinet body 100. The air inlet 401 and the air outlet 402 are particularly located at the same height. The air duct 400 is arranged in a n-shaped shape, and the charging module 200 and the fan 300 are adjacently arranged in the air duct 400 in a horizontal direction. A central axis of the charging module 200 in a vertical direction and a rotation axis of the fan 300 are particularly located on the same straight line, which is beneficial for cooling of the charging module 200 by cooling air and arrangement of the fan 300.

[0022] By arranging the n-shaped air duct, cooling air does not blow directly to the charging module 200 along a straight line from the air inlet 401 and blow out from the fan 300 through the air outlet 402 along a straight line, but can achieve the effect of a labyrinth air duct. In addition, the charging module 200 and the fan 300 are not arranged on a straight line with the air inlet 401 and the air outlet 402, but are arranged in a horizontal section of the n-shaped air duct, so that noise of the high-speed operating fan 300 is not directly transmitted to the outside through the air inlet 401 and the air outlet 402, but needs to be reflected and blocked by the n-shaped air duct 400, thereby greatly reducing the noise of the charging pile 10 during operation.

[0023] In an embodiment of the present application, two partition plates 110 are arranged in the cabinet body 100, and the partition plates 110 sequentially partition the cabinet body 100 into a first sub-space 101, a second sub-space 102 and a third sub-space 103. The charging module 200 is arranged in the second sub-space 102 between the two partition plates 110, and an inlet 111 and an outlet 112 for cooling air are arranged on the two partition plates 110 at two sides of the charging module 200. The fan 300 is arranged in the third sub-space 103. In this embodiment, this arrangement of the internal space of the cabinet body is not only beneficial for formation of the n-shaped air duct 400, but also beneficial for reasonably allocating space for other components in the charging pile 10. The charging module 200 is arranged in the middle space, can be better protected, is also beneficial for fully contacting cooling air, and improves cooling efficiency thereof.

[0024] It should be understood that the above-mentioned "partition plate" should be mainly understood as a component that plays a role of space partitioning in the cabinet body 100, other components such as electrical components can also be arranged thereon, and the partition plate can also be configured to have other shapes or other functions, all of which should be included in the protection scope of the present application.

[0025] In an embodiment of the present application, the air inlet 401 and the air outlet 402 have the same height and are arranged to be staggered from the charging module 200 and the fan 300 in height. That is, the "Ji"-shaped air duct 400 may be a "Ji" shape placed upright along the vertical direction or an inverted "Ji" shape. In Figure 2 , the air inlet and outlet 401 and 402 are lower than the charging module 200 and the fan 300 in height, and the air duct 400 is an upright "Ji" shape. With reference to Figure 3 , it shows a side view of a charging pile 10 proposed according to another embodiment of the present application. Figure 2 the air inlet and outlet 401 and 402 are higher than the charging module 200 and the fan 300 in height, and the air duct 400 is an inverted "Ji" shape.

[0026] In an embodiment of the present application, the air duct 400 includes a first sub-air duct 410 arranged in the first subspace 101, a second sub-air duct 420 arranged in the second subspace 102, and a third sub-air duct 430 arranged in the third subspace 103. The charging module 200 is arranged in the second sub-air duct 420, the fan 300 is arranged in the third sub-air duct 430, and the lengths of the first sub-air duct 410 and the third sub-air duct 430 in the vertical direction are greater than that of the second sub-air duct 420. In this embodiment, the air duct 400 does not occupy the entire subspace, but only a part of the subspace, so space for other components can be reserved in the subspace, which is also conducive to designing the size of the air duct 400, especially the width of the air duct 400, according to the size of the charging module 200.

[0027] In an embodiment of the present application, the first sub-air duct 410 includes a first connecting air duct 411 connected to the air inlet 401 and a first main air duct 412 connected to the inlet 111. The third sub-air duct 430 includes a third connecting air duct 431 connected to the air outlet 402 and a third main air duct 432 connected to the outlet 112. The first main air duct 412 and the third main air duct 432 extend in the horizontal direction, and the first connecting air duct 411 and the third connecting air duct 431 extend in the vertical direction. The first main air duct 412, the second sub-air duct 420 and the third main air duct 432 all extend in the horizontal direction, which is conducive to guiding the cooling air from the charging module 200 to the fan 300 in the horizontal direction. The first connecting air duct 411 and the third connecting air duct 431 form two vertical sides of the "Ji" shape, which are used to extend longitudinally to the air inlet 401 and the air outlet 402, so as to guide the cooling air in the vertical direction.

[0028] In one embodiment of this application, the width of the first connecting duct 411 is smaller than the width of the first subspace 101, and the width of the third connecting duct 431 is smaller than the width of the third subspace 103. This allows space for other components to be arranged next to the first connecting duct 411 and the third connecting duct 431, which is beneficial for improving the space utilization of the charging pile 10. In one embodiment of this application, a circuit breaker 500 is arranged horizontally adjacent to the first connecting duct 411 in the first subspace 101, and a branch output row 600 is arranged horizontally adjacent to the third connecting duct 431 in the third subspace 103.

[0029] In one embodiment of this application, the fan 300 has a wind pressure of 350 Pa or higher. Using a high-pressure fan 300 can improve the cooling effect and efficiency of the charging module 200.

[0030] In one embodiment of this application, the charging stack 10 includes a plurality of charging modules 200 arranged at uniform intervals in a vertical direction. Each charging module 200 is fitted with an inlet 111 and an outlet 112 on a partition 110. The plurality of charging modules 200 are particularly arranged between two partitions 110, and are particularly sandwiched between the two partitions 110. In one embodiment of this application, in the case of a plurality of charging modules 200, the horizontal axis of symmetry of the plurality of charging modules 200 is particularly collinear with the rotation axis of the fan 300.

[0031] In one embodiment of this application, the charging stack 10 includes 24 charging modules 200 and 24 charging branches connected to them respectively. In this embodiment, the number of charging modules 200 and charging branches is exactly matched to the number of battery packs in a typical vehicle, allowing high-power charging capacity to be output to all 24 batteries simultaneously, thereby meeting the user's fast charging needs and reducing charging time.

[0032] In summary, the charging stack proposed in one embodiment of this application adopts a Z-shaped air duct, which prevents the fan from being directly arranged at the air inlet and outlet. While ensuring that the charging module can be well cooled, the Z-shaped air duct significantly reduces the output noise of the high-speed fan, thereby improving the overall noise reduction capability of the charging stack.

[0033] It should be understood that all the above preferred embodiments are exemplary and not restrictive, and various modifications or variations made by those skilled in the art to the specific embodiments described above under the concept of this application should be within the scope of legal protection of this application.
