Description

Technical Field

[0001] The present application relates to the technical field of equipment heat dissipation, and particularly relates to a heat dissipation control method for a high-voltage box, an electronic device, and a storage medium. Background Art

[0002] With the rapid development of new energy technologies, the power demand of outdoor cabinets continues to increase, and their heat dissipation problems have become increasingly prominent. A large amount of heat is generated during the operation of the high-voltage box of the outdoor cabinet. If the heat dissipation is poor, it will cause the equipment to overheat, affect its insulation performance and service life, and may even lead to safety accidents.

[0003] However, traditional high-voltage boxes generally adopt a sealed structure and lack an effective active heat dissipation design. They only rely on natural heat dissipation or simple ventilation holes for heat exchange. Therefore, the heat generated by internal components cannot be evenly dissipated, resulting in local overheating, accelerating equipment aging, and reducing reliability. In addition, the existing heat dissipation solutions for high-voltage boxes are difficult to match the dynamically changing heat dissipation requirements under high-power working conditions, and are prone to thermal runaway risks in high-temperature environments or during continuous high-load operation.

[0051] Please refer to Figure 1 , Figure 1 which is a schematic flow chart of the high-voltage box heat dissipation control method provided by the embodiments of the present application. The specific process of this high-voltage box heat dissipation control method can be as follows:

[0052] 101. Determine the heat dissipation demand and associated fan operation parameters based on the heat generation characteristics and working condition data of the internal components of the high-voltage box;

[0053] Specifically, for step 101, during the charging and discharging processes of the high-voltage box, a large amount of heat is generated by the main components. To accurately determine the heat dissipation requirements, it is first necessary to collect the heat generation characteristics and operating condition data of these components in real time. For example, by installing temperature sensors at key positions inside the high-voltage box, the temperature changes of the components are monitored in real time. Through current sensors and voltage sensors, the current and voltage changes of the high-voltage box under different operating conditions are monitored, and thus the heat generation of the components is calculated. The collected data is transmitted to the control unit for real-time processing and analysis, providing a basis for the subsequent calculation of heat dissipation requirements. Then, based on the thermodynamic model, according to the collected heat generation characteristics and operating condition data, the total heat generation and temperature rise gradient distribution parameters of the high-voltage box are calculated. According to the calculated heat dissipation requirements, the operating parameters of the associated fan are determined, including the air volume range, wind pressure parameters, and speed regulation strategy.

[0054] Optionally, in some embodiments, step 101, "determine the heat dissipation requirements and the operating parameters of the associated fan based on the heat generation characteristics and operating condition data of the components inside the high-voltage box", may specifically include:

[0055] Collect the heat generation characteristics and operating condition data of the target components inside the high-voltage box in real time;

[0056] Specifically, by installing high-precision temperature sensors at key positions inside the high-voltage box, the temperature changes of the components are monitored in real time. Through current sensors and voltage sensors, the current and voltage changes of the high-voltage box under different operating conditions are monitored, and thus the heat generation of the components is calculated. The collected data is transmitted to the control unit through a high-speed communication interface to ensure the real-time and accuracy of the data. In addition to the heat generation characteristics, the operating condition data of the high-voltage box also needs to be collected, including the charge and discharge state, ambient temperature, and load change. Through the state monitoring sensor, the charge and discharge state of the high-voltage box is monitored in real time to determine the current working mode; through the ambient temperature sensor, the ambient temperature outside the high-voltage box is monitored to evaluate its impact on the heat dissipation requirements; through the load sensor, the load change of the high-voltage box is monitored to predict the future heat dissipation requirements.

[0057] In addition, the wireless sensor network (WSN) technology can be adopted to realize the collaborative work of multiple sensors inside the high-voltage box, improving the accuracy and reliability of data collection. Integrate the edge computing function on the sensor node to perform preliminary processing and analysis on the collected data, reduce the data transmission volume, and improve the system response speed. At the same time, fuse the data of different types of sensors to generate more comprehensive heat generation characteristics and operating condition data, providing more accurate input for the subsequent calculation of heat dissipation requirements

[0058] Based on the thermodynamic model, according to the heat generation characteristics and operating condition data, calculate the total heat generation and temperature rise gradient distribution parameters of the high-voltage box;

[0059] Specifically, based on the physical characteristics and operating conditions of the components inside the high-voltage box, a thermodynamic model is established. The thermodynamic model can specifically include a heat conduction model, a convection model, and a radiation model. The heat conduction model is used to consider the heat conduction effect between components and predict the conduction path of heat inside the high-voltage box; the convection model is used to consider the influence of air convection on heat dissipation and predict the effect of air flow on heat dissipation; the radiation model is used to consider the thermal radiation effect on the surface of components and predict the contribution of thermal radiation to heat dissipation.

[0060] Based on the thermodynamic model, combined with the collected heat generation characteristics and operating condition data, the total heat generation of the high-voltage box is calculated. For example, according to the power loss and operating time of the components, the total heat generation and power loss of the high-voltage box under different operating conditions are calculated. Through thermal balance analysis, the heat distribution inside the high-voltage box is determined, and the high-temperature area and temperature rise gradient are predicted. Through the thermodynamic model, the distribution parameters of the temperature rise gradient inside the high-voltage box are calculated. For example, using computational fluid dynamics (CFD) software, the temperature field inside the high-voltage box is simulated to generate a temperature distribution map, and according to the temperature distribution map, the temperature rise gradient inside the high-voltage box is calculated to determine the high-temperature area and the distribution parameters of the temperature rise gradient.

[0061] In addition, by combining the thermodynamic model with the fluid dynamics model, a multi-physics field coupling model is constructed to more accurately predict the temperature distribution and air flow distribution inside the high-voltage box. Machine learning algorithms, such as neural networks or support vector machines, can also be used to train and optimize the thermodynamic model to improve the prediction accuracy of the model. In the actual process, the temperature field inside the high-voltage box can also be monitored and analyzed in real time through the developed real-time thermal management software to generate a heat dissipation requirement report, providing a scientific basis for subsequent heat dissipation control.

[0062] Based on the total heat generation and the distribution parameters of the temperature rise gradient, the heat dissipation requirement of the high-voltage box is determined;

[0063] Specifically, according to the calculated total heat generation and the distribution parameters of the temperature rise gradient, the heat dissipation requirement of the high-voltage box is evaluated. First, according to the design standards and safety requirements of the high-voltage box, heat dissipation targets are set, including the target temperature range and temperature rise limit. Then, according to the total heat generation and the distribution parameters of the temperature rise gradient, the heat dissipation requirements of the high-voltage box under different operating conditions are calculated to ensure that the heat dissipation system can meet the actual use requirements. Next, according to the magnitude and distribution of the heat dissipation requirements, the heat dissipation requirements are classified. The high heat dissipation requirement areas inside the high-voltage box are determined, such as near high-heat-generating components. The low heat dissipation requirement areas inside the high-voltage box are determined, such as near low-heat-generating components. Finally, a heat dissipation requirement distribution map is generated to visually display the heat dissipation requirement distribution inside the high-voltage box.

[0064] In addition, through an intelligent heat dissipation control system, according to the heat dissipation demand distribution map, the operating parameters of the heat dissipation equipment can be dynamically adjusted to achieve precise heat dissipation; time series analysis or prediction models can be used to predict the heat dissipation demand of the high-voltage box and adjust the heat dissipation system in advance to ensure the heat dissipation effect. And through optimization algorithms such as genetic algorithms or particle swarm optimization algorithms, the heat dissipation demand is optimized to improve the efficiency and reliability of the heat dissipation system.

[0065] Match and associate the air volume range, air pressure parameters, and speed regulation strategy of the corresponding fan according to the heat dissipation demand;

[0066] Specifically, according to the heat dissipation demand, select a suitable fan. According to the total heat generation and temperature rise gradient distribution parameters, determine the required air volume range to ensure that the fan can provide sufficient heat dissipation capacity. According to the flow channel structure and air flow resistance inside the high-voltage box, determine the air pressure parameters of the fan to ensure that the air flow can be evenly distributed. Then, according to the structure and heat dissipation demand of the high-voltage box, select a suitable fan type, such as a centrifugal fan or an axial flow fan. Next, according to the heat dissipation demand, formulate a speed regulation strategy for the fan. For example, according to the change range of the heat dissipation demand, determine the speed regulation range of the fan to ensure that the fan can operate efficiently under different working conditions; design a speed regulation algorithm to dynamically adjust the fan speed according to the real-time monitored temperature data to achieve energy saving and efficient heat dissipation. Finally, the speed regulation control of the fan is realized through the controller to ensure the accurate execution of the speed regulation strategy.

[0067] In addition, this embodiment can adopt intelligent speed regulation control algorithms such as fuzzy control or neural network control to realize the intelligent speed regulation of the fan and improve the intelligent level of the heat dissipation system; install multiple fans inside the high-voltage box and realize the coordinated operation of multiple fans through a coordinated control algorithm to improve the heat dissipation efficiency; through an optimization algorithm, optimize the operating parameters of the fan to achieve energy saving and efficient heat dissipation and reduce energy consumption.

[0068] This embodiment can accurately determine the heat dissipation demand by collecting the heat generation characteristics and working condition data of the internal components of the high-voltage box in real time and combining with the thermodynamic model to calculate the total heat generation and temperature rise gradient distribution parameters, ensuring that the heat dissipation system can operate efficiently under different working conditions; by setting the heat dissipation target and matching the fan operating parameters, ensure that the high-voltage box operates within a safe temperature range and reduce the safety risks caused by overheating; by dynamically adjusting the fan speed, achieve energy saving and efficient heat dissipation, improve the overall performance of the heat dissipation system, can adapt to different working conditions and environmental conditions, has strong versatility and flexibility, and is suitable for high-power use conditions of outdoor cabinets.

[0069] 102. Construct a dynamic air flow model of the internal flow channel of the high-voltage box and optimize the flow channel structure and air flow distribution of the high-voltage box based on fluid mechanics principles;

[0070] Specifically, for step 102, to achieve a uniform temperature distribution inside the high-voltage box, it is necessary to optimize the flow channel structure and air flow distribution, which can specifically include flow channel interface design, side hole array setting, and air flow distribution optimization. For example, Figure 2 as shown Figure 2 is the overall structural schematic diagram of the high-voltage box provided in this embodiment. For example, according to Bernoulli's equation, the cross-section of the flow channel is designed to gradually contract along the air flow direction to ensure dynamic balance of the static pressure inside the flow channel, so that the air outlet velocity of each cross-section is consistent. A side hole array with an equal static pressure distribution is set on the side wall of the flow channel, and the air flow is guided by a deflector plate to cover the high-heat generation area to ensure uniform air flow distribution. Through fluid mechanics simulation, the shape and size of the flow channel are optimized to reduce air flow resistance and improve heat dissipation efficiency. In addition, computational fluid dynamics (CFD) software can also be used to simulate the air flow inside the high-voltage box and analyze the distribution of the air flow velocity field and pressure field. According to the simulation results, the shape and size of the flow channel are adjusted, and the position and number of side holes are optimized to ensure that the air flow can evenly cover all areas inside the high-voltage box, especially the high-heat generation area.

[0071] Optionally, in some embodiments, step 102, "Construct a dynamic air flow model for the internal flow channel of the high-voltage box and optimize the flow channel structure and air flow distribution of the high-voltage box based on fluid mechanics principles", can specifically include:

[0072] Design the cross-section of the flow channel of the high-voltage box to gradually contract along the air flow direction until the dynamic balance of the static pressure inside the flow channel is achieved;

[0073] Specifically, to achieve a uniform temperature distribution inside the high-voltage box, it is necessary to optimize the flow channel structure and air flow distribution. First, design the flow channel interface: design the cross-section of the flow channel to gradually contract along the air flow direction to ensure dynamic balance of the static pressure inside the flow channel. Based on fluid mechanics principles, by gradually reducing the cross-sectional area, the air flow velocity is gradually increased, thereby improving the heat dissipation efficiency. Then, by adjusting the shape and size of the flow channel cross-section, ensure that the static pressure of each cross-section inside the flow channel remains in dynamic balance, which helps to reduce air flow resistance and improve the uniformity and stability of the air flow.

[0074] In addition, adopt advanced flow channel optimization algorithms, such as genetic algorithm (GA) or particle swarm optimization algorithm (PSO), to optimize the design of the shape and size of the flow channel cross-section to further improve the heat dissipation efficiency; combine the temperature field, flow field, and structural stress to construct a multi-physics field coupling simulation model, simulate the heat dissipation efficiency and box deformation of the high-voltage box under different working conditions, generate simulation results, and provide a scientific basis for the flow channel design.

[0075] Calculate the dynamic pressure difference between adjacent cross-sections inside the flow channel based on Bernoulli's equation, and control the air outlet wind speed to be consistent through the dynamic pressure difference;

[0076] Specifically, according to Bernoulli's equation, the dynamic pressure difference between adjacent cross-sections in the flow channel is calculated. The specific steps include: calculating the dynamic pressure difference between adjacent cross-sections in the flow channel according to Bernoulli's equation to ensure that the air outlet velocities of each cross-section are consistent, which helps to achieve uniform temperature distribution inside the high-voltage box and improve the heat dissipation efficiency; by adjusting the shape and size of the flow channel cross-section, controlling the air velocity at the air outlet to ensure uniform air flow distribution, thereby reducing local overheating phenomena and improving the overall performance of the heat dissipation system.

[0077] In addition, intelligent control algorithms such as fuzzy control or neural network control can be adopted to dynamically adjust the air velocity at the air outlet to ensure uniform air flow distribution. A real-time monitoring system is established to monitor the air velocity and temperature inside the high-voltage box in real time, and the monitoring data is fed back to the control unit to achieve dynamic adjustment of the air velocity. At the same time, multiple fans are installed inside the high-voltage box, and through cooperative control algorithms, the cooperative operation of multiple fans is achieved to further improve the heat dissipation efficiency.

[0078] Side hole arrays with equal static pressure distribution are arranged on the side walls of the flow channel, and the air flow is guided by a deflector to cover the high-heat generation areas;

[0079] Specifically, the steps for arranging side hole arrays with equal static pressure distribution on the side walls of the flow channel include: determining the positions and quantities of the side holes according to the flow channel design. The side holes should be evenly distributed to ensure that the air flow can evenly cover all areas inside the high-voltage box, especially the high-heat generation areas. A small round hole design (diameter less than 16 mm) is adopted to reduce the impact of stamping and hole opening on the box body strength. At the same time, through laser drilling technology, the accuracy and quality of the side holes are ensured. The air flow is guided by a deflector to cover the high-heat generation areas, and the shape and position of the deflector are designed to ensure that the air flow can effectively cover the high-heat generation areas. The deflector should be optimized according to the flow channel structure and air flow distribution. The deflector material is selected as high-strength and corrosion-resistant materials such as stainless steel or aluminum alloy to improve the durability and reliability of the deflector.

[0080] In addition, the intelligent deflector can dynamically adjust the angle and position of the deflector according to the real-time monitored air velocity and temperature data to ensure that the air flow can evenly cover the high-heat generation areas. Combining the temperature field, flow field and structural stress, a multi-physics field coupling simulation model is constructed to simulate the influence of the deflector on the air flow distribution, generate simulation results, and provide a scientific basis for the deflector design.

[0081] In this embodiment, by optimizing the flow channel structure and air flow distribution, the temperature distribution inside the high-voltage box is more uniform, the heat dissipation efficiency is greatly improved, effectively solving the problem of insufficient heat dissipation in the prior art; the small round hole design and laser drilling process are adopted, reducing the impact of the opening on the structural strength of the box body, and at the same time the optimized opening distribution further reduces the stress concentration, extending the service life of the high-voltage box; the design of dynamically adjusting the heat dissipation parameters and opening distribution enables the high-voltage box to adapt to different working conditions and environmental conditions, with strong versatility and flexibility.

[0082] 103. Determine the opening parameters and processing technology according to the process characteristics and structural strength requirements of the high-voltage box, and process the high-voltage box according to the opening parameters through the processing technology;

[0083] Specifically, for step 103, in order to reduce the impact of the ventilation holes on the structural strength of the box body, it is necessary to reasonably determine the opening parameters. Determine the positions and quantities of the air outlet holes on both sides and the end face according to the opening positions and quantities designed by the flow channel. The closer the air outlet holes on both sides are to the air supply end, the larger the opening rate; for the end face air outlet holes from the middle to both sides, the opening rate gradually decreases. Adopt the small round hole design (diameter less than 16 mm) to reduce the impact of stamping openings on the box body strength. Select a suitable processing technology to ensure the accuracy and quality of the openings. For example, adopt the laser drilling process to process small round holes with a diameter less than 16 mm, reducing the impact of stamping openings on the box body strength. Set chamfers at the edges of the holes to reduce stress concentration and enhance the structural strength of the box body.

[0084] Optionally, in some embodiments, step 103 “Determine the opening parameters and processing technology according to the process characteristics and structural strength requirements of the high-voltage box, and process the high-voltage box according to the opening parameters through the processing technology” may specifically include at least one or a combination of the following:

[0085] The opening rate of the side holes of the high-voltage box close to the air supply end decreases according to the distance, and the opening rate at the end decreases to 30%-50% of the initial value;

[0086] Specifically, in order to optimize the air flow distribution inside the high-voltage box, it is necessary to reasonably design the opening rate of the side holes. As shown in the figure, the opening rate of the side holes of the high-voltage box close to the air supply end decreases according to the distance, that is, the closer to the air supply end, the larger the opening rate, and the farther from the air supply end, the smaller the opening rate. Based on the principle of fluid mechanics, by adjusting the opening rate, the distribution of the air flow inside the high-voltage box is made more uniform. The opening rate at the end decreases to 30%-50% of the initial value to ensure that the air flow can still maintain a certain flow rate at the end of the high-voltage box, avoiding the rapid attenuation of the air flow at the end, thereby improving the heat dissipation efficiency.

[0087] In addition, optimization algorithms such as genetic algorithm (GA) or particle swarm optimization algorithm (PSO) can be adopted to optimize the design of the opening ratio distribution, further improving the uniformity of air flow distribution and the heat dissipation efficiency. By combining the temperature field, flow field and structural stress, a multi-physical field coupling simulation model is constructed to simulate the heat dissipation effect and the deformation of the box body under different opening ratio distributions, generating simulation results to provide a scientific basis for the opening ratio design.

[0088] The opening ratio of the air outlet holes on the end face of the high-voltage box decreases linearly or exponentially from the center to both sides.

[0089] Specifically, in order to further optimize the air flow distribution inside the high-voltage box, the opening ratio of the air outlet holes on the end face needs to be reasonably designed. The opening ratio of the air outlet holes on the end face of the high-voltage box decreases linearly or exponentially from the center to both sides, that is, from the center to both sides, the opening ratio gradually decreases. This design is based on the principle of fluid mechanics. By adjusting the opening ratio, the air flow distribution inside the high-voltage box becomes more uniform. According to the actual requirements and design objectives, a linear or exponential law is selected for the decrease of the opening ratio. The linear law is simple and easy to implement, while the exponential law can better adapt to the complex air flow distribution requirements.

[0090] In addition, optimization algorithms such as genetic algorithm (GA) or particle swarm optimization algorithm (PSO) can be adopted to optimize the design of the opening ratio distribution of the air outlet holes on the end face, further improving the uniformity of air flow distribution and the heat dissipation efficiency. By combining the temperature field, flow field and structural stress, a multi-physical field coupling simulation model is constructed to simulate the heat dissipation effect and the deformation of the box body under different opening ratio distributions, generating simulation results to provide a scientific basis for the opening ratio design.

[0091] Use the laser drilling process to machine round holes with a diameter smaller than the preset threshold, and set chamfers to reduce stress concentration.

[0092] Specifically, in order to reduce the influence of the ventilation holes on the structural strength of the box body, the laser drilling process is adopted for hole opening processing. The specific steps include: designing round holes with a diameter smaller than the preset threshold, usually with a diameter smaller than 16 mm. The small round hole design can reduce the weakening of the box body structure while maintaining good heat dissipation effects; using the laser drilling process for machining, the laser drilling has the characteristics of high precision, high efficiency and low heat affected zone, which can ensure the accuracy and quality of the holes; setting chamfers at the edges of the holes to reduce stress concentration.

[0111] Dynamically adjust the opening distribution parameters and the fan start-stop logic with the calibrated multi-physics field coupling simulation model;

[0112] Specifically, a dynamic adjustment algorithm is developed to dynamically adjust the opening distribution parameters and the fan start-stop logic according to the simulation results of the calibrated multi-physics field coupling simulation model; the operating state of the high-voltage box is monitored in real time by sensors, and the monitoring data is fed back to the dynamic adjustment system to achieve dynamic adjustment; the effect of the dynamic adjustment is evaluated through the multi-physics field coupling simulation model to ensure the performance of the heat dissipation system.

[0115] Optionally, in some embodiments, the high-voltage box heat dissipation control method provided in this embodiment may further specifically include:

[0116] Configure a positive pressure blowing system on the air inlet side of the high-voltage box to form a directional pressurized air flow field, so that the pressure difference between the inside and outside of the box is greater than a preset pressure difference threshold.

[0117] Specifically, in order to optimize the air flow organization inside the high-voltage box and improve the heat dissipation effect, a positive pressure blowing system can be configured on the air inlet side of the high-voltage box. The specific steps include: designing a positive pressure blowing system, including a fan, an air duct, and a control device. The fan is responsible for providing a directional pressurized air flow, the air duct is responsible for guiding the air flow into the high-voltage box, and the control device is responsible for adjusting the operating parameters of the fan. Select a suitable fan according to the heat dissipation requirements and structural characteristics of the high-voltage box. The fan should have sufficient air volume and air pressure to ensure that the air flow can be evenly distributed throughout the high-voltage box. Design the shape and size of the air duct to ensure that the air flow can smoothly enter the high-voltage box and be evenly distributed. The air duct should minimize the air flow resistance and improve the uniformity and stability of the air flow. In addition, intelligent control algorithms, such as fuzzy control or neural network control, can be used to achieve the automatic control of the positive pressure blowing system. Dynamically adjust the operating parameters of the fan according to the real-time monitored temperature data and air flow data to ensure the uniformity and stability of the air flow. At the same time, multiple fans can also be installed on the air inlet side of the high-voltage box, and through a cooperative control algorithm, the cooperative work of multiple fans can be achieved. The cooperation of multiple fans can improve the uniformity and stability of the air flow and further improve the heat dissipation effect. By optimizing the operating parameters of the fan, energy conservation and efficient heat dissipation can be achieved. For example, the rotation speed of the fan can be dynamically adjusted according to the real-time monitored temperature data to ensure that the energy consumption is minimized on the premise of meeting the heat dissipation requirements.

[0118] After forming a directional pressurized air flow field, design the directional pressurized air flow field to ensure that the air flow can be evenly distributed throughout the high-pressure box. The air flow field should minimize vortices and dead zones to improve the uniformity and stability of the air flow. By adjusting the operating parameters of the fan, control the pressure difference inside and outside the box. The pressure difference should be greater than the preset pressure difference threshold to ensure that the air flow can smoothly enter the high-pressure box and be evenly distributed. Real-time monitor the pressure difference inside and outside the box through a pressure difference sensor to ensure that the pressure difference is always greater than the preset pressure difference threshold. If the pressure difference is lower than the preset threshold, automatically adjust the operating parameters of the fan to restore the pressure difference.

[0119] In addition, the pressure difference inside and outside the box can be monitored in real time, and the monitoring data can be fed back to the control unit. According to the feedback data, dynamically adjust the operating parameters of the fan to ensure that the pressure difference is always greater than the preset threshold. By setting the pressure difference threshold and the anomaly detection algorithm, realize the real-time monitoring of the pressure difference inside and outside the box. Once the pressure difference anomaly is detected, immediately issue a warning signal to ensure the safe operation of the equipment.

[0120] In this embodiment, by configuring a positive pressure blowing system on the air inlet side of the high-pressure box to form a directional pressurized air flow field, making the pressure difference inside and outside the box greater than the preset pressure difference threshold, ensuring that the air flow can be evenly distributed throughout the high-pressure box, significantly improving the heat dissipation efficiency; by optimizing the design and control parameters of the air flow field, reducing the impact and vibration of the air flow on the structure of the high-pressure box, enhancing the structural strength and stability of the high-pressure box; by real-time monitoring the pressure difference inside and outside the box, ensuring that the pressure difference is always greater than the preset threshold, preventing external air from entering the high-pressure box, and reducing the safety risks caused by the entry of dust and moisture.

[0121] Optionally, in some embodiments, the high-pressure box heat dissipation control method provided in this embodiment may specifically further include:

[0122] Obtain the real-time temperature data inside the high-pressure box;

[0123] Specifically, deploy high-precision temperature sensors at key positions inside the high-pressure box to real-time monitor the temperature changes inside the high-pressure box. The temperature sensors can be thermocouples, thermistors, etc., which can quickly respond to temperature changes and generate electrical signals. The temperature data collected by the temperature sensors is transmitted to the control unit through wired or wireless communication methods. The control unit performs real-time processing on the data, including filtering, amplification, analog-to-digital conversion, etc., to ensure the accuracy and reliability of the data. The control unit stores the processed temperature data in the local memory for subsequent analysis and historical data query. At the same time, the data can also be transmitted to the remote monitoring center through the network to achieve remote monitoring and management.

[0124] In addition, the wireless sensor network (WSN) technology can be adopted to enable the collaborative work of multiple temperature sensors, improving the accuracy and reliability of data collection. The WSN technology can reduce the wiring complexity and lower the system cost. Integrating edge computing capabilities on sensor nodes to preliminarily process and analyze the collected temperature data, reducing the data transmission volume and improving the system response speed.

[0125] Dynamically adjust the fan speed based on real-time temperature data;

[0126] Specifically, based on the real-time temperature data, establish a relationship model between temperature and fan speed. When the temperature rises, increase the fan speed to improve the heat dissipation efficiency; when the temperature drops, reduce the fan speed to save energy. Adopt the PID control algorithm or other intelligent control algorithms (such as fuzzy control, neural network control, etc.) to dynamically adjust the fan speed according to the real-time temperature data. The control algorithm can be adjusted according to the preset temperature-speed curve to ensure that the fan speed matches the actual heat dissipation requirements. Set the adjustment range of the fan speed according to the design requirements of the high-voltage box and the performance parameters of the fan. For example, the fan speed can be dynamically adjusted between 1000 rpm and 5000 rpm to meet the heat dissipation requirements under different temperature conditions.

[0127] In addition, intelligent speed control algorithms such as fuzzy control or neural network control can be adopted to achieve the adaptive adjustment of the fan speed. The intelligent speed control algorithm can automatically optimize the speed control strategy according to the real-time temperature data and historical data, improving the intelligence level of the heat dissipation system. Install multiple fans inside the high-voltage box and achieve the collaborative work of multiple fans through the collaborative control algorithm. The collaboration of multiple fans can improve the heat dissipation efficiency, reduce the load of a single fan, and extend the service life of the fan.

[0128] When it is detected based on the real-time temperature data that the temperature difference in any area inside the high-voltage box is greater than the preset temperature difference threshold, control the eddy current generator to start generating lateral turbulence;

[0129] Specifically, detect the temperature difference between different areas inside the high-voltage box through the real-time temperature data. When the temperature difference in any area is greater than the preset temperature difference threshold, trigger the eddy current generator to start. The eddy current generator can be a vortex generator, an airfoil spoiler, etc., which can generate lateral turbulence, break the boundary layer, and enhance the convective heat transfer. Dynamically adjust the operating parameters of the eddy current generator, such as the rotation speed, turbulence intensity, etc., according to the size and position of the temperature difference. The turbulence control strategy can adopt the PID control algorithm or other intelligent control algorithms to ensure that the turbulence effect matches the actual heat dissipation requirements.

[0130] In this embodiment, by obtaining the temperature data inside the high-voltage box in real time and dynamically adjusting the fan speed and the operating parameters of the eddy current generator, it can quickly respond to temperature changes and significantly improve the heat dissipation efficiency; through intelligent speed control and turbulence control, it realizes the energy-saving operation of the fan and the eddy current generator and reduces energy consumption; through the lateral turbulence generated by the eddy current generator, it breaks the boundary layer, enhances convective heat transfer, makes the temperature distribution inside the high-voltage box more uniform, and reduces local overheating phenomena; through real-time monitoring and intelligent control, it ensures the stable operation of the high-voltage box under different working conditions, reduces the safety risks caused by overheating, and improves the reliability and service life of the system.

[0131] Optionally, in some embodiments, the high-voltage box heat dissipation control method provided in this embodiment may further specifically include:

[0132] Obtain the current ambient temperature, load fluctuation data, and dust concentration of the high-voltage box;

[0133] Specifically, by installing a high-precision temperature sensor outside the high-voltage box, the temperature of the environment where the high-voltage box is located is monitored in real time. Through current sensors and voltage sensors, the load changes of the high-voltage box are monitored in real time. The load fluctuation data reflects the working state of the high-voltage box in different time periods, including the current and voltage changes during the charging and discharging processes. Through a dust concentration sensor, the dust concentration around the high-voltage box is monitored in real time. The dust concentration data is crucial for evaluating the performance and safety of the heat dissipation system because dust entering the inside of the high-voltage box may lead to a decrease in heat dissipation efficiency and safety hazards. The ambient temperature, load fluctuation data, and dust concentration data are fused and processed to generate more comprehensive operating state information, providing richer data support for subsequent heat dissipation control.

[0134] Based on the ambient temperature, load fluctuation data, and dust concentration, the matching relationship between the opening ratio threshold of the high-voltage box and the fan speed is optimized in real time;

[0135] Specifically, the obtained ambient temperature, load fluctuation data, and dust concentration data are transmitted to the control unit for real-time processing and analysis. For example, the control unit evaluates the heat dissipation requirements and operating state of the high-voltage box according to the monitoring data. For example, according to the ambient temperature and dust concentration, the opening ratio threshold of the high-voltage box is dynamically adjusted. In a high-temperature or high-dust-concentration environment, the opening ratio threshold is appropriately reduced to reduce the risk of dust entering the inside of the high-voltage box; in a low-temperature or low-dust-concentration environment, the opening ratio threshold is appropriately increased to improve the heat dissipation efficiency. According to the load fluctuation data and ambient temperature, the fan speed is dynamically adjusted. In a high-load or high-temperature environment, the fan speed is increased to improve the heat dissipation efficiency; in a low-load or low-temperature environment, the fan speed is reduced to save energy.

[0136] By establishing a mathematical model between the ambient temperature, load fluctuation data, dust concentration, and the orifice opening rate threshold and fan speed, the matching relationship between the orifice opening rate threshold and the fan speed is optimized in real time. Ensure that the heat dissipation system of the high-voltage box can operate efficiently under different environmental conditions.

[0137] In addition, through a real-time monitoring system, the operating status of the high-voltage box is monitored in real time, and the monitoring data is fed back to the control unit. According to the feedback data, the matching relationship between the orifice opening rate threshold and the fan speed is dynamically adjusted to ensure the efficient operation of the heat dissipation system.

[0138] In this embodiment, by optimizing the matching relationship between the orifice opening rate threshold and the fan speed in real time, the heat dissipation system of the high-voltage box can dynamically adjust the heat dissipation parameters according to the changes in ambient temperature, load fluctuation, and dust concentration, significantly improving the heat dissipation efficiency; through an intelligent optimization algorithm, the dynamic adjustment of the fan speed is realized to ensure that, on the premise of meeting the heat dissipation requirements, the energy consumption is minimized and the energy utilization efficiency is improved; through real-time monitoring and dynamic adjustment, the stable operation of the high-voltage box under different environmental conditions is ensured, the safety risks caused by overheating or dust entry are reduced, and the reliability and service life of the system are improved.

[0139] To facilitate the understanding of the high-voltage box heat dissipation control method provided in this embodiment, this embodiment also provides a specific implementation manner of the high-voltage box heat dissipation control method, and the detailed process is as follows:

[0140] First, calculate the heat generation of the main components during the charging and discharging processes of the high-voltage box and select the fan type.

[0141] Then, for an air-cooled high-voltage box, when ignoring the heat transferred by heat conduction between it and the outside air and internal components, to achieve the goal of relatively uniform temperature inside the high-voltage box, the flow rates of each flow channel should be as uniform as possible. According to the principle of fluid mechanics, to ensure that the air outlet speeds of each equal-section air outlet are equal, the basic condition is that the static pressures of each side hole are equal, that is, the static pressure remains unchanged throughout the entire length of the main pipe;

[0142] According to Bernoulli's equation, for two adjacent cross-sections in the flow channel:

[0143] P i +ρv i 2 / 2 = P i+1 +ρv i+1 2 / 2 + δP q (1)

[0144] When P i = P i+1 , then δP q = ρv i2 / 2 - ρv i+1 2 / 2(2);

[0145] Where P i is the static pressure (Pa) at the i-th or (i + 1)-th section, v i is the flow velocity (m / s) at the i-th or (i + 1)-th section, δP q is the total pressure loss (Pa) between the two sections, and ρ is the air density.

[0146] It can be seen from Equation (1) that the condition for maintaining equal static pressure between any two sections is that the dynamic pressure drop between the two sections is equal to the resistance loss between the two sections. Usually, the right end of Equation (1) is greater than the left end. If the two ends are to be equal, the cross-sectional area should gradually decrease along the flow direction. The static pressure velocity (unit: m / s) in the direction perpendicular to the duct wall of the air outlet is:

[0147]

[0148] Vi is the air volume passing through the side hole (unit: m3 / s);

[0149] L 0 = μf 0 v i (4)

[0150] L 0 is the average velocity of air passing through the side hole (unit: m / s)

[0151] V 0 = L 0 / f 0 = μv i (5)

[0152] Where: μ is the flow coefficient of the side hole, f 0 is the area of the side hole.

[0153] From the above content, it can be obtained that the position and number of the air outlet holes on both sides and the end face should follow the following rules: The closer the air outlet holes on both sides are to the air supply end, the larger the opening ratio. For the air outlet holes on the end face, from the middle to both sides, the opening ratio becomes lower and lower.

[0154] It can be obtained from the temperature field simulation that for the two groups of simulation experiment models, the end face openings also correspond to two groups respectively, and the heat dissipation and ventilation effects are better at this time.

[0155] To minimize the influence of opening ventilation holes on the strength of the plate, small round holes (φ < 16) are used, and laser drilling is adopted to reduce the influence of stamping and opening waist-shaped holes on the strength.

[0156] In summary, for the high-voltage box heat dissipation control method provided by the embodiments of the present application, first, based on the heat generation characteristics and operating condition data of the internal components of the high-voltage box, the heat dissipation requirements and associated fan operating parameters are determined; then, a dynamic air flow model of the internal flow channel of the high-voltage box is constructed, and based on the principles of fluidics, the flow channel structure and air flow distribution of the high-voltage box are optimized; next, according to the process characteristics and structural strength requirements of the high-voltage box, the opening parameters and processing technology are determined, and the high-voltage box is processed according to the opening parameters through the processing technology; finally, the heat dissipation effect of the processed high-voltage box is verified through the constructed multi-physical field coupling model, a heat dissipation verification result is generated, and the corresponding heat dissipation control parameters of the high-voltage box are dynamically adjusted based on the heat dissipation verification result. The high-voltage box heat dissipation control solution provided by the embodiments of the present application determines the heat dissipation requirements and fan operating parameters by comprehensively considering the heat generation characteristics and operating condition data of the internal components of the high-voltage box, optimizes the flow channel structure and air flow distribution using the principles of fluidics, accurately determines the opening parameters and processing technology to meet the process characteristics and structural strength requirements, and verifies the heat dissipation effect and dynamically adjusts the heat dissipation control parameters through the multi-physical field coupling model, thereby realizing the refined and intelligent control of the high-voltage box heat dissipation process, effectively improving the heat dissipation efficiency of the high-voltage box, and improving the safety and reliability of the high-voltage box. At the same time, the rationality of the structural strength and processing technology is taken into account, and the heat dissipation requirements of the high-voltage box of the outdoor cabinet under high-power operating conditions can be met, effectively reducing the safety risk.
