[0036] In the subsequent description, the suffixes such as "module", "component", or "unit" used to represent elements are only for the convenience of description of the present application, and have no specific meaning. Therefore, "module", "component", or "unit" can be mixedly used.

[0037] The following will be described in detail respectively. It should be noted that the description order of the following embodiments is not limited as the priority order of the embodiments.

[0038] Please refer to Figure 1 and Figure 2 , Figure 1 The structure schematic diagram of the outdoor cabinet high-voltage box provided by the embodiments of the present application is shown. The outdoor cabinet high-voltage box comprises a box body, wherein, for example, Figure 1 and Figure 2As shown, the box body has a first side plate and a second side plate arranged oppositely, and the first side plate and the second side plate are sequentially provided with a plurality of groups of heat dissipation structures along a first direction (the first direction can be a left-to-right direction as shown Figure 1 or a right-to-left direction as shown in the middle). Figure 1 Specifically, the box body of the high-voltage box has a first side plate and a second side plate arranged oppositely, which provides a basic layout for heat dissipation of the high-voltage box, so that the heat dissipation structures can be evenly distributed on both sides of the box body. In addition, each group of heat dissipation structures includes a plurality of heat dissipation holes, and the heat dissipation holes penetrate the first side plate and / or the second side plate. The pitch of the heat dissipation holes in the adjacent two groups of heat dissipation structures increases or decreases, which helps to optimize the flow path of the airflow and enhance the heat dissipation effect.

[0039] Specifically, the box body of the high-voltage box has a first side plate and a second side plate arranged oppositely, which provides a basic layout for heat dissipation of the high-voltage box, so that the heat dissipation structures can be evenly distributed on both sides of the box body. In addition, each group of heat dissipation structures includes a plurality of heat dissipation holes, and the heat dissipation holes penetrate the first side plate and / or the second side plate. The pitch of the heat dissipation holes in the adjacent two groups of heat dissipation structures increases or decreases, which helps to optimize the flow path of the airflow and enhance the heat dissipation effect.

[0040] Each group of heat dissipation structures includes a plurality of heat dissipation holes, and the heat dissipation holes penetrate the first side plate and / or the second side plate, wherein in the plurality of groups of heat dissipation structures: the pitch of the adjacent two heat dissipation holes in the first group of heat dissipation structures is L1, the pitch of the adjacent two heat dissipation holes in the second group of heat dissipation structures is L2, and the pitch of the adjacent two heat dissipation holes in the other groups is Ln; and L1≤L2≤Ln.

[0041] Specifically, the first side plate and the second side plate are sequentially provided with a plurality of groups of heat dissipation structures along the first direction, so that the heat dissipation structures are orderly distributed on the side plates and can effectively guide the dissipation of heat. The pitch of the heat dissipation holes in the adjacent two groups of heat dissipation structures increases or decreases, for example, the pitch of the adjacent two heat dissipation holes in the first group of heat dissipation structures is L1, the pitch of the adjacent two heat dissipation holes in the second group of heat dissipation structures is L2, and the pitch of the adjacent two heat dissipation holes in the other groups is Ln, and L1≤L2≤Ln, so that the pitch of the heat dissipation holes gradually increases along the first direction, forming a kind of gradually changing heat dissipation structure layout.

[0042] The gradual change design of the spacing of the heat dissipation holes helps to optimize the airflow organization inside the cabinet. When the airflow enters the cabinet, the area with smaller spacing of the heat dissipation holes can provide greater airflow resistance, allowing the airflow to be more evenly distributed throughout the entire cabinet interior, avoiding local airflow concentration, thereby improving the heat dissipation efficiency, reducing the internal temperature of the cabinet, and improving the safety factor of the energy storage outdoor cabinet. Compared with uniformly distributed heat dissipation holes, the gradually changing heat dissipation hole layout can reduce the impact on the strength of the cabinet side panel due to excessive concentration of heat dissipation holes while ensuring the heat dissipation effect. By reasonably adjusting the spacing of the heat dissipation holes, a better balance between heat dissipation needs and structural strength can be achieved, ensuring the stability and reliability of the high-voltage cabinet in actual use. In particular, different heat-generating devices at different positions in the outdoor cabinet may have different heat outputs, and the gradual change design of the spacing of the heat dissipation holes can better adapt to such differences in heat output, providing relatively dense heat dissipation holes for areas with larger heat outputs to enhance the heat dissipation effect; in areas with smaller heat outputs, the spacing of the heat dissipation holes is appropriately increased to avoid excessive heat dissipation, achieving a reasonable allocation of heat dissipation resources.

[0043] As can be seen, the outdoor cabinet high-voltage cabinet provided in the embodiment can optimize the airflow organization inside the cabinet by arranging multiple groups of heat dissipation structures on the first and second side panels and increasing or decreasing the spacing of the heat dissipation holes in adjacent two groups of heat dissipation structures, so that the airflow can pass through the heat dissipation holes more evenly, improving the heat dissipation efficiency, and the optimized heat dissipation structure can effectively reduce the temperature inside the high-voltage cabinet, thereby improving the safety factor of the entire energy storage outdoor cabinet.

[0044] Optionally, in some embodiments, each group of the heat dissipation structure includes a plurality of heat dissipation holes, and the plurality of heat dissipation holes are arrayed on the first side panel and / or the second side panel.

[0045] Specifically, as Figure 1 and Figure 2As shown, each group of heat dissipation structures in the embodiment includes a plurality of heat dissipation holes, which are arrayed on the first side plate and / or the second side plate. Among them, arrayed means that the heat dissipation holes are arranged according to certain rules and intervals to form an ordered heat dissipation hole array. The arrayed heat dissipation holes on the first side plate and / or the second side plate can evenly cover the surface of the side plate, ensuring the uniformity and effectiveness of the heat dissipation effect. By arraying the heat dissipation holes on the first side plate and / or the second side plate, the uniform distribution of the heat dissipation holes on the side plate can be ensured, thereby achieving uniform heat dissipation effect, which helps to avoid local overheating and improve the heat dissipation efficiency of the entire high-voltage box. The arrayed heat dissipation holes can guide the airflow to pass through the side plate evenly, optimizing the airflow organization inside the box, which helps to improve the heat dissipation efficiency and reduce the temperature inside the box. Moreover, the arrayed heat dissipation holes increase the heat dissipation area of the side plate, so that more heat can be dissipated through the heat dissipation holes. By increasing the heat dissipation area, the heat dissipation efficiency can be improved, and the temperature inside the high-voltage box can be reduced. By optimizing the distribution of the heat dissipation holes, the heat transfer resistance on the side plate can be reduced, thereby reducing the thermal resistance to improve the heat dissipation efficiency and ensure that the temperature inside the high-voltage box can be quickly reduced.

[0046] Optionally, in some embodiments, the density of the heat dissipation holes in each group of the plurality of groups of heat dissipation structures gradually increases or gradually decreases according to the arrangement order of the plurality of groups of heat dissipation structures.

[0047] Optionally, in some embodiments, the plurality of heat dissipation hole arrays form a rectangular heat dissipation structure.

[0048] Optionally, in some embodiments, the plurality of heat dissipation hole arrays form a circular heat dissipation structure.

[0049] Specifically, the shape of the heat dissipation holes can be further optimized, such as using circular, rectangular or other shaped heat dissipation holes to improve the heat dissipation effect. Different shapes can affect the airflow flow path and heat dissipation efficiency. The size of the heat dissipation holes can be adjusted according to actual needs, such as setting larger heat dissipation holes in areas with larger heat generation and smaller heat dissipation holes in areas with smaller heat generation, to further optimize the heat dissipation effect. The arrangement of the heat dissipation holes can also be optimized, and the interval of the heat dissipation holes can be adjusted according to actual needs, such as setting smaller intervals in areas with larger heat generation and larger intervals in areas with smaller heat generation, to further optimize the heat dissipation effect. The arrangement direction of the heat dissipation holes can be optimized, such as arranging along the airflow direction to enhance the airflow flow effect and further improve the heat dissipation efficiency.

[0050] Among them, the material of the heat dissipation holes can be selected from materials with good thermal conductivity, such as aluminum alloy, copper, etc., to improve the heat dissipation effect. The manufacturing process of the heat dissipation holes can adopt laser drilling, stamping, etc. to ensure the precision and quality of the heat dissipation holes. Different manufacturing processes can affect the performance and life of the heat dissipation holes.

[0051] Optionally, in some embodiments, the opening density of the heat dissipation structure decreases from 3.6±0.2 holes / cm 2 to 1.6±0.2 holes / cm 2 .

[0052] Specifically, the opening density of the heat dissipation structure in the embodiment decreases from 3.6±0.2 holes / cm 2 to 1.6±0.2 holes / cm 2 , that is, the density of the heat dissipation holes gradually decreases at different positions of the box. The gradient coefficient can be k=0.026, which represents the rate of change of the density of the heat dissipation holes. The density of the heat dissipation holes can be adjusted according to the length of the box to adapt to different heat dissipation needs.

[0053] In specific embodiments, the array of heat dissipation holes is distributed on the first side plate and / or the second side plate, so that the heat dissipation holes can uniformly cover the surface of the side plate, ensuring the uniformity and effectiveness of the heat dissipation effect; the position and number of the heat dissipation holes are optimized according to the gradient coefficient, so that the distribution of the heat dissipation holes is more reasonable and can better adapt to the heat dissipation needs inside the box.

[0054] The embodiment can achieve gradient heat dissipation inside the box through the gradient change of the opening density of the heat dissipation holes. In the area with larger heat generation, the density of the heat dissipation holes is higher (the spacing is larger), which can quickly dissipate heat; in the area with smaller heat generation, the density of the heat dissipation holes is lower (the spacing is smaller), which avoids excessive heat dissipation. The gradient change of the heat dissipation holes design makes the heat inside the box be dissipated more uniformly, avoids local overheating, and improves the heat dissipation efficiency of the entire high-voltage box. By optimizing the distribution of the heat dissipation holes, the heat dissipation area of the side plate is increased, so that more heat can be dissipated through the heat dissipation holes, improving the heat dissipation efficiency. The gradient change of the heat dissipation hole design reduces the heat transfer resistance on the side plate, reduces the thermal resistance, and ensures that the temperature inside the high-voltage box can be quickly reduced.

[0055] Optionally, in some embodiments, the gradient coefficient k and the length L of the box satisfy the relationship k=0.021+0.00017L, where L is in mm.

[0056] Specifically, the gradient coefficient k in the embodiment satisfies the following relationship with the length L of the box: k = 0.021 + 0.00017L, where the unit of L is mm. It can be seen that as the length of the box increases, the gradient coefficient k also increases accordingly, thereby adjusting the density variation of the heat dissipation holes, so that the density of the heat dissipation holes can better adapt to the box of different lengths, further optimizing the heat dissipation effect. The position and number of the heat dissipation holes are optimized according to the gradient coefficient, so that the distribution of the heat dissipation holes is more reasonable, and can better adapt to the heat dissipation demand inside the box. In addition, the value of the gradient coefficient k can be further optimized through simulation technology to achieve the best heat dissipation effect.

[0057] Optionally, in some embodiments, the hole diameter R of the heat dissipation hole ranges from 12mm to 16mm.

[0058] Specifically, the hole diameter R of the heat dissipation hole in the embodiment ranges from 12mm to 16mm, aiming to balance the heat dissipation efficiency and structural strength. Selecting the hole diameter range of 12mm to 16mm can ensure that the heat dissipation hole provides sufficient heat dissipation area while not excessively weakening the structural strength of the box. A larger hole diameter can increase the cross-sectional area of airflow passing through, thereby improving the heat dissipation effect. Using a small round hole design and laser drilling technology reduces the impact of punching on the strength of the plate, while reducing the processing problem of edge burrs, thereby enhancing the structural strength of the box.

[0059] In addition, the hole diameter can be further optimized according to the actual heat dissipation demand and the requirement of the structural strength of the box. For example, the hole diameter can be appropriately increased in the area with a larger heat generation, and the hole diameter can be appropriately reduced in the area with a smaller heat generation. Through simulation technology, the hole diameter can be further optimized to achieve the best balance between heat dissipation effect and structural strength.

[0060] Optionally, in some embodiments, the heat dissipation holes in each group of heat dissipation structures are arranged in a radial manner, with a density of 2.8±0.3 holes / cm 2 in the center area, and a cosine function distribution attenuation to 0.9±0.1 holes / cm 2 at the edge.

[0061] Specifically, the heat dissipation holes in each group of heat dissipation structures in the embodiment are arranged in a radial manner, and the heat dissipation holes gradually spread from the central area to the edge area, forming a radial heat dissipation hole layout. The heat dissipation hole density of the central area is 2.8±0.3 holes / cm2, which helps to quickly dissipate heat in the central area with a large amount of heat. The heat dissipation hole density of the edge area is 0.9±0.1 holes / cm2. The lower heat dissipation hole density helps to reduce unnecessary heat dissipation holes in the edge area with a small amount of heat, thereby optimizing the heat dissipation effect. Among them, the density of the heat dissipation holes is distributed in a cosine function from the central area to the edge area, so that the density of the heat dissipation holes changes more smoothly, avoiding the influence of sudden density changes on the heat dissipation effect. Through the cosine function distribution, the density of the heat dissipation holes gradually changes between the central area and the edge area, forming a smooth density gradient.

[0062] The high-density heat dissipation hole design of the central area in the embodiment can quickly dissipate heat in the area with a large amount of heat, effectively reducing the temperature of the central area; the low-density heat dissipation hole design of the edge area can reduce unnecessary heat dissipation holes and avoid excessive heat dissipation, while the density change in the cosine function distribution makes the heat dissipation effect more uniform; the radial arrangement of the heat dissipation holes increases the heat dissipation area, so that more heat can be dissipated through the heat dissipation holes, improving the heat dissipation efficiency; by optimizing the distribution and density change of the heat dissipation holes, the heat transfer resistance in the box body is reduced, the thermal resistance is reduced, and the temperature inside the high-voltage box can be quickly reduced; the reasonable distribution of the heat dissipation holes avoids local stress concentration and enhances the structural strength of the box body.

[0063] Optionally, in some embodiments, it further comprises: a heat dissipation fin;

[0064] The box body has a third side plate perpendicular to the first side plate and / or the second side plate; the third side plate is provided with a mounting portion, and the heat dissipation fins are arranged on the mounting portion in a predetermined direction, and a flow guide channel is formed between adjacent two heat dissipation fins.

[0065] Specifically, as shown in Figure 3 The outdoor cabinet high-voltage box provided by the embodiment can further be provided with a heat dissipation fin, and the box body of the high-voltage box has a third side plate perpendicular to the first side plate and / or the second side plate. The heat dissipation fins are arranged on the mounting portion of the third side plate in a predetermined direction. The heat dissipation fins are used to increase the heat dissipation area, as Figure 4As shown, through the arrangement of multiple fins, multiple flow guide channels are formed to guide airflow through, thereby improving heat dissipation efficiency. The flow guide channels are formed between two adjacent heat dissipation fins. These flow guide channels enable airflow to pass through the heat dissipation fins in an orderly manner, allowing more heat to be dissipated through the fins. The design of the flow guide channels optimizes the airflow organization inside the box, enabling airflow to pass through the heat dissipation fins in an orderly manner, improving the contact efficiency of airflow and fins, and thereby improving the heat dissipation effect. The flow guide channels enable airflow to pass through the heat dissipation fins in an orderly manner, avoiding airflow turbulence and improving heat dissipation efficiency. Through the design of the flow guide channels, heat inside the box can be dissipated more evenly, avoiding local overheating.

[0066] In addition, the shape of the heat dissipation fins can be further optimized, such as adopting a wavy shape, a zigzag shape, etc., to increase the heat dissipation area and the degree of airflow turbulence, and improve the heat dissipation effect. The size of the heat dissipation fins can be adjusted according to actual heat dissipation needs, such as setting larger fins in areas with larger heat generation and smaller fins in areas with smaller heat generation. The shape of the flow guide channels can be further optimized, such as adopting a gradually expanding shape, a gradually tapering shape, etc., to improve the flow efficiency of airflow. The number of flow guide channels can be adjusted according to actual heat dissipation needs, such as setting more flow guide channels in areas with larger heat generation and fewer flow guide channels in areas with smaller heat generation. The material of the heat dissipation fins can be selected to have good thermal conductivity, such as aluminum alloy, copper, etc., to improve the heat dissipation effect. The surface of the heat dissipation fins can be treated in a special way, such as oxidation treatment, coating treatment, etc., to improve the heat dissipation efficiency and corrosion resistance.

[0067] Optionally, in some embodiments, it further comprises a heat conduction member;

[0068] The box has a fourth side plate, and the fourth side plate and the third side plate are oppositely arranged; the heat conduction member is arranged on the fourth side plate, and the heat conduction member is arranged along the bending on the fourth side plate.

[0069] Specifically, as Figure 5As shown, the outdoor cabinet high-voltage box provided by the embodiment can further be provided with a heat conduction member. The box body of the high-voltage box has a fourth side plate, and the fourth side plate is oppositely arranged with the third side plate. The heat conduction member is arranged on the fourth side plate and forms a convection heat dissipation structure with the heat dissipation fins on the third side plate. The heat conduction member is arranged along the fourth side plate in a bent manner, effectively increasing the surface area of the heat conduction member and improving the heat conduction efficiency. The main function of the heat conduction member is to quickly conduct the heat inside the box body to the heat dissipation fins, so that the heat is dissipated through the heat dissipation fins. The heat conduction member and the heat dissipation fins form a convection heat dissipation structure, so that the heat can be conducted from the inside of the box body to the heat dissipation fins through the heat conduction member, and then dissipated through the heat dissipation fins, optimizing the heat dissipation path and improving the heat dissipation efficiency. Meanwhile, the bent arrangement of the heat conduction member not only increases the heat conduction area and avoids local stress concentration, but also further enhances the structural strength of the box body, avoids weakening the strength of the box body due to the increase of the heat dissipation structure, and enables the heat conduction member to better withstand the heat and pressure inside the box body.

[0070] In addition, the heat conduction member can be made of high-thermal-conductivity materials such as copper, aluminum, etc., to further improve the heat conduction efficiency. Composite materials such as copper-aluminum alloy can also be considered to combine the advantages of different materials and improve the performance of the heat conduction member. The shape of the heat conduction member can be further optimized, for example, in a wavy or zigzag design, to increase the heat conduction area and the degree of turbulence of the airflow, and to improve the heat dissipation effect. The size of the heat conduction member can be adjusted according to actual heat dissipation requirements, for example, larger heat conduction members are arranged in areas with larger heat generation, and smaller heat conduction members are arranged in areas with smaller heat generation. The surface of the heat conduction member can be treated in a special way, such as oxidation treatment or coating treatment, to improve the heat conduction efficiency and corrosion resistance.

[0071] Optionally, in some embodiments, it further comprises a driving assembly;

[0072] The high-voltage box has a fifth side plate between the first side plate and the second side plate. The fifth side plate is provided with a heat dissipation flow channel, and the driving assembly is arranged in the heat dissipation flow channel. The driving assembly is used to discharge the airflow in the box body through the driving assembly.

[0073] Specifically, as Figure 6 As shown, the outdoor cabinet high-voltage box provided by the embodiment can further be provided with a driving assembly. The high-voltage box has a fifth side plate between the first side plate and the second side plate. The fifth side plate is provided with a heat dissipation flow channel, and the driving assembly is arranged in the heat dissipation flow channel. The main function of the driving assembly is to discharge the airflow in the box body through the heat dissipation flow channel, thereby enhancing the heat dissipation effect. The driving assembly can be a fan, an air blower or other types of airflow driving devices.

[0074] The heat dissipation flow channel is arranged on the fifth side plate for guiding the airflow in the box to be discharged through the driving assembly. The design of the heat dissipation flow channel enables the airflow to pass through the box in an orderly manner, taking away the heat inside. The design of the heat dissipation flow channel optimizes the airflow organization inside the box, enabling the airflow to contact the heat dissipation structure more effectively and improving the heat dissipation efficiency. Through the operation of the driving assembly, the speed and flow of the airflow can be significantly improved, thereby taking away more heat. The design of the heat dissipation flow channel enables the airflow to pass through the interior of the box uniformly, avoiding local overheating and improving the heat dissipation effect of the entire high-voltage box. The active heat dissipation function of the driving assembly makes the heat dissipation process more efficient. Compared with natural convection heat dissipation, active heat dissipation can lower the temperature inside the box more quickly. Through the operation of the driving assembly, the accumulation of heat inside the box is reduced, and the thermal resistance is lowered, enabling the heat to be dissipated more quickly. In addition, the shape of the heat dissipation flow channel can be further optimized, such as adopting a gradually expanding shape, a gradually tapering shape, etc., to improve the flow efficiency of the airflow. The number of heat dissipation flow channels can be adjusted according to actual heat dissipation needs, such as arranging more heat dissipation flow channels in areas with higher heat generation and fewer heat dissipation flow channels in areas with lower heat generation.

[0075] The type of driving assembly can be a fan, an air blower, and a blower, etc., and different types of fans can be adopted, such as centrifugal fans, axial flow fans, etc., to adapt to different heat dissipation needs. The air blower is suitable for devices with relatively uniform heat distribution and complex air ducts, and can form negative pressure to prevent dust from entering the box. The blower is suitable for components with concentrated heat generation, and can form positive pressure in the box to prevent dust from entering and prolong the service life of the equipment. The driving assembly can be controlled by an intelligent control system, and the operating speed of the driving assembly can be automatically adjusted according to the temperature inside the box to achieve energy saving and efficient heat dissipation. Multi-stage control can be set up to adjust the operating mode of the driving assembly according to different heat dissipation needs to adapt to different working conditions.

[0076] Optionally, in some embodiments, the heat dissipation holes are drilled by a pulse laser.

[0077] Specifically, the heat dissipation holes of the high-voltage box in the embodiment can be drilled by a pulse laser. Pulse laser drilling is a high-precision and high-efficiency processing technology that can accurately control the size, shape, and position of the holes to achieve high-precision hole processing, smooth hole edges, and no burrs, maintaining the consistency of the size of the heat dissipation holes, which helps to improve the heat dissipation efficiency of the heat dissipation holes and reduce the structural strength problems caused by poor hole processing. Pulse laser drilling can ensure uniform distribution of the heat dissipation holes, making the heat dissipation effect more uniform and avoiding local overheating. High-precision heat dissipation hole processing enables the airflow to pass through the heat dissipation holes more smoothly, improving the heat dissipation efficiency. In addition, pulse laser drilling can reduce the impact of hole processing on the structural strength of the box, avoiding stress concentration caused by poor hole processing.
