Description

Technical Field

[0001] This utility model relates to the field of high-voltage box equipment technology, and in particular to a high-voltage box. Background Technology

[0002] High-voltage switchgear typically houses various types of high-voltage electrical components. These components generate significant heat when operating under high loads, causing a substantial rise in the internal temperature of the switchgear. This temperature increase directly impacts the switchgear's normal operation, necessitating effective cooling measures to maintain its proper functioning. Currently, common cooling methods on the market fall into two main categories: water cooling and air cooling.

[0003] While liquid-cooled high-voltage boxes excel in meeting waterproof design requirements, their complex structure and the need for cooling components like liquid cooling plates to be arranged according to the heat generation of electrical components are crucial for effective cooling of high-voltage devices. Furthermore, the specifications and locations of high-voltage components vary between different high-voltage cabinets, necessitating customized design of cooling component positions and shapes for each cabinet. This results in poor versatility and significant challenges in design, manufacturing, and maintenance, leading to high costs. Air-cooled high-voltage boxes typically require dedicated air inlets and outlets to ensure airflow, but this design struggles to achieve high-level protection standards and can easily allow moisture and impurities to be drawn into the cabinet, potentially damaging the high-voltage components.

Specifically, the airflow within the circulating air duct circulates the air within the enclosure. Driven by a fan, high-temperature gas from the enclosure is drawn into the circulating air duct through the air inlet, where it exchanges heat with the liquid-cooled flow channel, lowering the gas temperature.

[0042] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0043] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0044] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0045] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0046] like Figures 1 to 5 As shown, a high-pressure box in this embodiment includes a box body 100, a heat exchange component 200, and a cooling component 300. The box body 100 has a receiving cavity 101 for installing electrical components 400. The heat exchange component 200 is disposed in the receiving cavity 101 and includes a circulating air duct 210 and a fan 220. The circulating air duct 210 has an air inlet 211 and an air outlet 212, both of which are connected to the receiving cavity 101. The fan 220 is disposed at the air inlet 211 and / or the air outlet 212 of the circulating air duct 210. The cooling component 300 includes a liquid cooling channel 310, which is disposed at least on one side of the circulating air duct 210 for cooling the circulating air duct 210. The liquid cooling channel 310 has a liquid inlet 320 and a liquid outlet 330, both of which are connected to the outside of the box body 100.

[0047] In this embodiment, by abutting the liquid cooling channel 310 and the circulating air channel 210, an organic combination of air cooling and liquid cooling is achieved. Specifically, the airflow in the circulating air channel 210 enables air circulation within the receiving cavity 101. Driven by the fan 220, the high-temperature gas in the receiving cavity 101 is drawn into the circulating air channel 210 from the air inlet 211, where it exchanges heat with the liquid cooling channel 310, thus lowering the temperature of the high-temperature gas. Then, the cooled low-temperature gas is discharged back into the receiving cavity 101 through the air outlet 212, thereby reducing the temperature of the air within the receiving cavity 101. This invention achieves internal air circulation cooling and heat dissipation within the receiving cavity 101 of the housing 100, avoiding the need for openings in the housing 100, maintaining the overall protective performance of the housing 100, while also achieving effective cooling and heat dissipation. Compared to traditional liquid cooling solutions that require customized flow channels for different electrical components 400, the liquid cooling flow channel 310 of this invention can achieve a standardized flow channel design, has wide versatility, and can significantly reduce design and manufacturing costs. The inlet 320 and outlet 330 of the liquid cooling flow channel 310 are both connected to the outside of the housing 100, which facilitates the connection and maintenance of the external cooling system and avoids sealing problems caused by openings in the housing 100.

[0048] In one embodiment, the length of the circulating air duct 210 extends along a first direction, with the air inlet 211 and air outlet 212 respectively located at both ends of the circulating air duct 210 along its length. This layout helps to create a smoother airflow path, allowing the high-temperature gas in the receiving cavity 101 to be drawn into the circulating air duct 210 more efficiently. When the fan 220 starts, it generates suction from the air inlet 211, rapidly drawing the air heated by the operation of the electrical components 400 into the circulating air duct 210. During this process, the high-temperature air undergoes sufficient heat exchange with the liquid-cooled flow channel 310 located adjacent to the circulating air duct 210. The cooling medium flowing in the liquid-cooled flow channel 310 continuously absorbs heat from the high-temperature air, causing the air temperature to gradually decrease. Subsequently, the cooled low-temperature air is discharged back into the receiving cavity 101 from the air outlet 212, and this cycle repeats continuously, lowering the air temperature in the receiving cavity 101 and ensuring that the high-voltage electrical components 400 in the high-voltage box can operate stably in a suitable temperature environment. Furthermore, by placing the air inlet 211 and the air outlet 212 at both ends of the length of the circulating air duct 210, the air flow distance within the circulating air duct 210 can be extended to the maximum extent, increasing the heat exchange time with the liquid cooling channel 310 and further improving the cooling effect.

[0049] In one embodiment, the high-pressure box further includes a base plate 1, the thickness direction of which extends along a second direction. Both the circulating air duct 210 and the liquid cooling channel 310 are disposed within the base plate 1, and are spaced apart along the second direction. Integrating the circulating air duct 210 and the liquid cooling channel 310 within the base plate 1 significantly optimizes the internal structure of the high-pressure box. On one hand, the base plate 1 provides stable support for the circulating air duct 210 and the liquid cooling channel 310, ensuring their relative positions remain fixed during operation, which is beneficial for stable heat exchange. On the other hand, this integrated design reduces the number of internal components, simplifies the assembly process, and improves the overall reliability and production efficiency of the high-pressure box. Simultaneously, because the circulating air duct 210 and the liquid cooling channel 310 are spaced apart along the second direction, they have sufficient contact area for heat exchange while avoiding mutual interference, ensuring efficient operation of both the air-cooling and liquid-cooling systems. Moreover, this layout facilitates the maintenance and repair of the circulating air duct 210 and the liquid cooling flow channel 310. When one of the systems malfunctions, it is easier to troubleshoot and repair, reducing maintenance costs and time.

[0050] In practical applications, substrate 1 can be customized according to the specific size and performance requirements of the high-voltage box to meet the needs of different scenarios. For example, for high-voltage boxes with limited space, the thickness of substrate 1 can be appropriately reduced, while the layout of the circulating air duct 210 and the liquid cooling flow channel 310 can be optimized to ensure efficient cooling and heat dissipation within a limited space. For high-voltage boxes with higher requirements for heat dissipation performance, the size of substrate 1 can be increased, and the scale of the circulating air duct 210 and the liquid cooling flow channel 310 can be expanded to improve heat exchange capacity.

[0051] like Figure 5 and Figure 8 As shown, in one embodiment, the substrate 1 includes a first plate 11 and a second plate 12. The first plate 11 is disposed on one side of the second plate 12 along a second direction. A liquid cooling channel 310 is disposed within the first plate 11, and a circulating air duct 210 is disposed within the second plate 12. This structural design cleverly places the liquid cooling channel 310 and the circulating air duct 210 in different plates, achieving a clear division of functions. The first plate 11 and the second plate 12 are fixed together by a reasonable assembly method, ensuring both the relative positional accuracy between them and facilitating disassembly and maintenance. The liquid cooling channel 310 is designed according to a specific path within the first plate 11 to ensure that the cooling medium can fully absorb heat. The circulating air duct 210 is arranged within the second plate 12, allowing air to flow smoothly and exchange heat with the liquid cooling channel 310. Furthermore, this separate plate design can be optimized for the first plate 11 and the second plate 12 according to actual needs. For example, the diameter and direction of the liquid cooling channel 310 can be adjusted to improve cooling efficiency, or the shape and size of the circulating air duct 210 can be optimized to improve airflow characteristics. Furthermore, when one board malfunctions, it can be replaced individually, reducing maintenance costs and complexity. Moreover, the separate board design improves process flexibility during production, allowing different boards to utilize different processing techniques and materials to meet their respective functional requirements.

[0052] In one embodiment, the cooling assembly 300 is detachably connected to the housing 100. Specifically, the first plate 11 can be detachably installed on one side wall of the housing 100 where the heat exchange assembly 200 is located by fasteners such as screws and bolts, which greatly facilitates the installation, maintenance and replacement of the cooling assembly 300.

[0053] like Figure 10As shown, in one embodiment, the housing 100 includes a first side plate 110, which includes a first side facing the receiving cavity 101 and a second side facing away from the receiving cavity 101. One side of the second plate 12 abuts against the first side, and the first plate 11 is detachably abutted against the second side. The first plate 11 is provided with a first groove 1101, and the second plate 12 is provided with a second groove 1201. A liquid cooling channel 310 is formed between the first side plate 110 and the first groove 1101, and a circulating air channel 210 is formed between the first side plate 110 and the second groove 1201.

[0054] Specifically, this structural design fully utilizes the space of the side panel of the enclosure 100, cleverly integrating the liquid cooling channel 310 and the circulating air duct 210 between the side wall of the enclosure 100 and the base plate 1. Through the arrangement of the first groove 1101 and the second groove 1201, independent liquid cooling channels 310 and circulating air ducts 210 are formed in conjunction with the first side panel 110, ensuring both relative independence and efficient heat exchange. The liquid cooling channel 310 is formed between the first side panel 110 and the first groove 1101, where the cooling medium flows, absorbing the heat transferred from the circulating air duct 210. The circulating air duct 210 is formed between the first side panel 110 and the second groove 1201, where air flows, bringing in the high-temperature gas from the receiving cavity 101. After heat exchange with the liquid cooling channel 310, the cooled low-temperature gas is then returned to the receiving cavity 101. This design not only optimizes the internal space layout of the high-pressure enclosure but also improves cooling efficiency, while facilitating assembly and maintenance. When the liquid cooling channel 310 or the circulating air channel 210 needs to be inspected, only the first plate 11 needs to be removed, without the need for large-scale disassembly of the entire housing 100, which greatly reduces the difficulty and cost of maintenance.

[0055] In actual operation, the enclosure 100 also includes a second side plate 120, two third side plates 130, and two fourth side plates 140. The second side plates 120 are spaced apart along a first direction, the two third side plates 130 are spaced apart along a second direction, and the two fourth side plates 140 are spaced apart along a third direction. The first side plate 110, the second side plate 120, the two third side plates 130, and the two fourth side plates 140 form a receiving cavity 101, with the first, second, and third directions perpendicular to each other. The receiving cavity 101 structure formed by the multiple side plates provides a stable and reliable installation space for the electrical components 400 inside the enclosure 100. The side plates are connected by reasonable methods, such as welding and bolting, ensuring the overall structural strength and sealing of the enclosure 100, effectively preventing external dust, moisture, and other impurities from entering the receiving cavity 101 and damaging the electrical components 400.

[0056] like Figures 11 to 13As shown, in one embodiment, the substrate 1 further includes a third plate 13. The third plate 13 and the first plate 11 are respectively disposed on both sides of the second plate 12 along the second direction. The liquid cooling channel 310 includes a first channel 311 and a second channel 312 that are interconnected. The first channel 311 is disposed within the first plate 11, and the second channel 312 is disposed within the third plate 13. This multi-plate structure design further enhances the flexibility and cooling efficiency of the liquid cooling system. By dividing the liquid cooling channel 310 into the first channel 311 and the second channel 312, and respectively disposed within the first plate 11 and the third plate 13, the cooling medium can be divided and a more uniform heat distribution can be achieved. The first channel 311 and the second channel 312 are interconnected, ensuring that the cooling medium can circulate throughout the liquid cooling system. Furthermore, the cooling medium simultaneously cools the circulating air duct 210 within the first channel 311 and the second channel 312, which can fully absorb the heat of the air in the circulating air duct 210 and improve the cooling efficiency. Meanwhile, this design also facilitates adjustments to the layout and dimensions of the liquid cooling channels 310 according to actual needs, such as increasing or decreasing the number of channels or changing their direction, to adapt to high-pressure boxes with different specifications and performance requirements. Furthermore, when a channel within a plate becomes blocked or damaged, that plate can be repaired or replaced individually without affecting the normal operation of other parts, improving the system's reliability and maintainability. In addition, the addition of the third plate 13 provides a more stable support structure for the base plate 1, enhancing the mechanical strength and stability of the entire high-pressure box.

[0057] In one embodiment, the liquid outlet 330 is located on the first plate 11 and communicates with the first flow channel 311, while the liquid inlet 320 is located on the third plate 13 and communicates with the second flow channel 312. The liquid inlet 320 and the liquid outlet 330 are located on the same side of the housing 100 along the second direction, making the connection of the external cooling system more convenient. Liquid inlet and outlet operations can be completed simply by connecting pipes on the same side of the housing 100. Simultaneously, by setting the liquid inlet 320 and the liquid outlet 330 on the third plate 13 and the first plate 11 respectively, and communicating with the corresponding second flow channel 312 and first flow channel 311, smooth circulation of the cooling medium within the liquid cooling flow channel 310 is ensured. The cooling medium enters the second flow channel 312 from the liquid inlet 320, flows within the third plate 13 and absorbs heat, then enters the first flow channel 311 through the connection point to continue flowing and further absorbing heat, finally flowing out from the liquid outlet 330, completing the entire cooling cycle. This design not only improves cooling efficiency but also facilitates maintenance and repair of the inlet 320 and outlet 330. In case of blockages or leaks, the problem can be quickly located and resolved, reducing repair time and costs. Furthermore, the fact that the inlet 320 and outlet 330 are located on the same side also benefits the piping layout and overall aesthetics of the external cooling system. In practical applications, the position and size of the inlet 320 and outlet 330 can be flexibly adjusted according to the specific requirements of the external cooling system and the installation environment of the high-pressure box to meet the needs of different scenarios.

[0058] Furthermore, the third plate 13 is located on the side of the second plate 12 facing the receiving cavity 101, while the first plate 11 is located on the side of the second plate 12 away from the receiving cavity 101. Specifically, by placing the third plate 13 on the side of the second plate 12 facing the receiving cavity 101, the liquid cooling channel 310 is located within the receiving cavity and closer to the heat source generated by the electrical device 400. When the cooling medium enters the third plate 13 from the inlet 320, it can not only cool the air in the circulating air duct 210 but also quickly absorb the heat from the air in the receiving cavity, improving cooling efficiency. Simultaneously, the first plate 11, located on the side of the second plate 12 away from the receiving cavity 101, provides convenient space for connecting external cooling systems, facilitating pipe installation and maintenance. In addition, in practical operation, this layout also provides flexibility for subsequent upgrades and improvements; for example, the number of plates can be increased or decreased as needed, or the layout of the liquid cooling channel 310 can be adjusted to adapt to different usage scenarios.

[0059] In one embodiment, the side of the first plate 11 that abuts against the second plate 12 has multiple protrusions 1102 facing the circulation duct 210. The side of the protrusions 1102 facing the liquid cooling channel 310 forms a third groove 1103 for the cooling medium to flow into. The protrusions 1102 increase the contact area between the first liquid cooling plate and the airflow within the circulation duct 210. When the airflow passes through the circulation duct 210, it makes full contact with the surface of the protrusions 1102, allowing the heat in the airflow to be transferred more quickly to the cooling medium within the first liquid cooling plate. Furthermore, the design of the third groove 1103 facilitates turbulence during the flow of the cooling medium, enhancing the heat exchange between the cooling medium and the inner wall of the liquid cooling plate, as well as the protrusions 1102, further improving the cooling efficiency of the airflow. Simultaneously, the presence of the protrusions 1102 also strengthens the structural strength of the first liquid cooling plate to a certain extent, enabling it to better withstand various external forces during long-term use and ensuring the stable operation of the cooling system.

[0060] In one embodiment, the surface of the protrusion 1102 is curved. This curved surface design not only enhances the structural strength of the first liquid cooling plate, enabling it to better withstand the pressure of the airflow within the circulating air duct 210 and the flow impact of the cooling medium, but also further increases the contact area between the first liquid cooling plate and the airflow within the circulating air duct 210. When the airflow passes through these curved protrusions 1102, it forms more complex turbulence. This turbulence can disrupt the airflow boundary layer, allowing the heat in the airflow to be transferred more quickly and fully to the cooling medium within the first liquid cooling plate. Simultaneously, the third groove 1103 formed by the curved protrusions 1102 provides a more stable flow channel for the cooling medium, ensuring that the cooling medium flows evenly across the first liquid cooling plate and avoiding localized overheating caused by poor flow, thereby improving the efficiency and stability of the entire cooling system. Furthermore, the curved surface design reduces the frictional resistance between the airflow and the first liquid cooling plate, reducing energy loss and making the cooling system more energy-efficient during operation.

[0061] In one embodiment, the electrical device 400 includes a heating element 410, with an air inlet 211 and / or an air outlet 212 facing the heating element 410. This design ensures that the airflow within the circulation duct 210 directly acts on the heating element 410, quickly removing the heat generated by the heating element 410. When the fan 220 is running, the airflow drawn in from the air inlet 211 preferentially flows through the area where the heating element 410 is located, fully absorbing the heat emitted by it, and then the heat-carrying airflow is discharged from the circulation duct 210 through the air outlet 212, achieving targeted heat dissipation.

[0062] In practical operation, the orientation of the air inlet 211 and air outlet 212 can be flexibly adjusted according to the specific location and heat dissipation requirements of the heat-generating device 410, which can better adapt to different layouts and types of high-pressure boxes, improving the versatility and practicality of the design. In practical operation, the fan 220 can be a centrifugal fan, blower 220, exhaust fan 220, etc. Of course, other blowing or exhaust equipment and structures can also be used, as long as the fan 220 can enable the air in the receiving cavity 101 to enter the circulating air duct 210 for circulation and cooling. Such designs are all within the protection scope of this utility model.

[0063] like Figure 2 and Figure 3 As shown, in one embodiment, a flow guide fan 500 is provided in the receiving cavity 101. The length direction of the circulation duct 210 extends along the first direction. The air inlet 211 and the air outlet 212 are respectively located at the two ends of the circulation duct 210 along the first direction. The flow guide fan 500 is located between the air inlet 211 and the air outlet 212 along the first direction. The flow guide fan 500 has an air inlet end and an air outlet end. The air inlet end is set towards the air outlet 212 along the first direction, and the air outlet end is set towards the air inlet 211 along the first direction. This structural design enables the flow guide fan 500 to effectively guide the airflow in the receiving cavity 101.

[0064] When the guide fan 500 operates, its inlet draws in the low-temperature gas returning from the outlet 212, while the outlet pushes the gas towards the inlet 211, where it mixes and exchanges heat with the newly drawn-in high-temperature gas within the circulation duct 210. This guiding effect not only enhances the air circulation efficiency within the circulation duct 210 but also makes the heat exchange process more uniform and thorough. With the assistance of the guide fan 500, the airflow within the circulation duct 210 flows more orderly, preventing airflow short-circuiting or stagnation, thereby improving the overall cooling system's heat dissipation effect. Simultaneously, the guide fan 500 also increases the airflow speed within the housing 101, increasing the air cooling circulation speed and improving cooling efficiency. In actual operation, the selection and installation location of the guide fan 500 need to be optimized based on the specific structure and heat dissipation requirements of the high-pressure box to ensure it achieves the best guiding and heat dissipation effects.

[0065] like Figure 2As shown, in one embodiment, a temperature sensor 600 is also provided inside the receiving cavity 101. The temperature sensor 600 is located adjacent to the heating element 410. The temperature sensor 600 can monitor the temperature around the heating element 410 in real time and feed the temperature data back to the control system. When the temperature exceeds a preset safety threshold, the control system will issue an alarm to alert the operator, allowing the operator to promptly detect the abnormality and take targeted measures, such as stopping the high-voltage cabinet from operating or adjusting the cooling component 300 to increase its cooling rate, thus avoiding equipment damage and safety accidents.

[0066] Specifically, the temperature sensor 600 is connected to both the fan 220 and the guide fan 500. Depending on the specific situation, electrical or Bluetooth signal connections can be used. When the temperature sensor 600 detects a temperature change within the containment cavity 101, it transmits the corresponding temperature signal to the control systems of the fan 220 and the guide fan 500. If the temperature rises above a certain range, the control system will increase the speed of the fan 220 according to a preset program, increasing the airflow speed within the circulation duct 210. This allows more high-temperature gas to be drawn into the circulation duct 210 for heat exchange with the liquid cooling channel 310. Simultaneously, the control system will adjust the operation of the guide fan 500, such as increasing its power to enhance its guiding effect on airflow within the containment cavity 101, promoting faster air circulation within the circulation duct 210 and accelerating the cooling process. Conversely, when the temperature drops to a suitable range, the control system will reduce the operating intensity of the fan 220 and the guide fan 500, achieving energy savings. This linkage control method between the temperature sensor 600, the fan 220, and the guide fan 500 can automatically and accurately adjust the operating status of the cooling system according to the actual temperature inside the containment cavity 101, ensuring that the high-pressure box is always in a suitable working temperature environment, and further improving the intelligence level and reliability of the high-pressure box cooling system.

[0067] like Figure 14As shown, in one embodiment, multiple baffles 213 are spaced apart within the circulating air duct 210. The length direction of the baffles 213 extends along a first direction, and the multiple baffles 213 are spaced apart along a third direction. The multiple baffles 213 divide the circulating air duct 210 into multiple sub-air ducts 214. The multiple sub-air ducts 214 can effectively guide the airflow to flow orderly within the circulating air duct 210, avoiding turbulence or short-circuiting. When the airflow enters the circulating air duct 210, it is separated into different airflow bundles by the multiple baffles 213, which flow in their respective sub-air ducts 214. In this way, the heat exchange process between the airflow and the liquid cooling channel 310 is more uniform and sufficient, because the airflow in each sub-air duct 214 can fully contact the liquid cooling channel 310 for heat transfer. At the same time, the arrangement of multiple sub-air ducts 214 also increases the contact area between the airflow and the liquid cooling channel 310, allowing more heat to be absorbed by the cooling medium in a short time, thereby improving the heat exchange efficiency of the entire cooling system. Furthermore, the baffles 213 can enhance the structural strength of the circulating air duct 210 to a certain extent, enabling it to better withstand airflow impact and external pressure during long-term use, thus ensuring the stable operation of the cooling system. In actual operation, the number, spacing, and length of the baffles 213 can be flexibly adjusted according to the specific heat dissipation requirements of the high-pressure box and the dimensions of the circulating air duct 210 to achieve the best cooling effect.
