[0023] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0024] See also Figure 1 The embodiment of the present application provides a method for optimizing the heat dissipation structure of a transformer, which is applicable to electronic equipment. The electronic equipment may be Figure 1 The server side in the implementation environment is shown.

[0025] In the following method embodiments, for ease of description, the execution subject of each step of the method is taken as an electronic device as an example for illustration, but this does not constitute a specific limitation.

[0026] like Figure 1 As shown, the method may include the following steps: S100, determining a corresponding target transformer, using a three-dimensional modeling tool to create a three-dimensional model corresponding to the target transformer and the use environment, and creating a virtual working environment corresponding to the target transformer based on VR technology.

[0027] First, the transformer model for which the heat dissipation structure is to be optimized is identified, and the corresponding target transformer is determined, including its electrical parameters, size and other basic information; then, a 3D modeling software (such as SolidWorks, AutoCAD, CATIA, etc.) is used to create a 3D model of the target transformer, including the transformer body, internal components (such as coils, cores) and casing; and at the same time, a 3D model of the physical space where the target transformer is located is created, including the installation location, peripheral equipment (such as switchgear, cable trays), ventilation system, etc.; the 3D model can accurately reflect the real physical characteristics of the transformer and its use environment, providing a basis for subsequent virtual simulation.

[0028] It should be pointed out here that the physical space, peripheral equipment and related facilities where the target transformer is located in the virtual working environment should be constructed to ensure that they are consistent with the actual situation; VR technology provides an immersive experience, allowing users to more intuitively understand and analyze the working environment of the transformer; through the virtual working environment, engineers can more easily observe and experiment, and improve the optimization efficiency of the heat dissipation structure.

[0029] S110, selecting a target VR platform, importing the three-dimensional model into the target VR platform, setting corresponding platform parameters based on the target transformer, integrating thermal simulation software in the virtual working environment, performing thermal simulation in the virtual working environment based on the actual heating situation and working environment conditions corresponding to the target transformer, and obtaining the transformer temperature distribution of the target transformer under different working conditions in the virtual working environment.

[0030] Among them, a suitable VR platform is selected according to the specific needs of the optimized design, such as Unity, Unreal Engine, etc., and then the created 3D model can be imported into the selected VR platform, and the relevant parameters of the VR platform, such as physical properties, material properties, etc., are set according to the type of target transformer; by setting the correct parameters, the transformer behavior in the virtual environment is ensured to be consistent with the actual one, and the selection of a suitable VR platform can improve development efficiency and shorten the development cycle.

[0031] During the thermal simulation process, thermal simulation software (such as ANSYS Fluent, Star-CCM+, etc.) can be integrated into the VR platform to perform thermal simulation. According to the actual heating conditions and working environment conditions of the target transformer, simulation parameters such as ambient temperature and air flow speed can be set. Then, thermal simulation can be run in a virtual environment to obtain the temperature distribution of the transformer under different working conditions.

[0032] Through thermal simulation, the temperature distribution of the transformer under different working conditions can be accurately analyzed to provide data support for subsequent heat dissipation design; and based on the simulation results, potential hot spots can be discovered to optimize the heat dissipation structure of the target transformer.

[0033] S120, designing a corresponding multi-layer fin structure based on the temperature distribution of the transformer, obtaining corresponding real-time temperature data of the target transformer in the virtual working environment, and automatically adjusting the rotation speed of a cooling fan in the transformer based on the real-time temperature data.

[0034] Among them, according to the results of thermal simulation, a multi-layer fin structure is designed to improve the heat dissipation performance. The spacing and thickness between each layer of fins are optimized through CFD simulation to ensure maximum heat dissipation efficiency. It should be pointed out that the fin structure is well matched with the transformer body without affecting the functions of other components. The optimized fin structure design can improve the heat dissipation efficiency and reduce the operating temperature of the transformer.

[0035] In addition, the real-time temperature data of the target transformer type is obtained in the virtual environment. Based on the real-time temperature data, the speed of the cooling fan is automatically adjusted through a preset algorithm to maintain the best heat dissipation effect, thereby ensuring that the fan speed can be dynamically adjusted under different working conditions to adapt to temperature changes.

[0036] By executing steps S100 to S120, the transformer heat dissipation structure optimization design method based on VR technology and CFD simulation can achieve accurate design and optimization of the transformer heat dissipation structure. This method not only improves the heat dissipation efficiency and reduces the operating temperature, but also achieves energy saving and noise reduction by dynamically adjusting the cooling fan speed, thereby significantly improving the operating stability and service life of the transformer.

[0037] It should be pointed out here that after designing the corresponding multi-layer fin structure based on the transformer temperature distribution, in order to determine the optimal heat dissipation structure, the method further performs the following steps: S121, performing thermal simulation of different multi-layer fin structures in a virtual working environment to obtain heat dissipation data corresponding to the different multi-layer fin structures in the virtual working environment.

[0038] Among them, based on the preliminary designed multi-layer fin structure, several different variants are designed, and each variant may involve fine-tuning of factors such as the spacing, thickness, and shape of the fins; and in the virtual working environment, for each different fin structure variant, corresponding thermal simulation parameters are set, including ambient temperature, air flow velocity, etc.; then, the thermal simulation software integrated in the VR platform is used to perform thermal simulation on each fin structure variant to obtain its heat dissipation data in the virtual working environment, such as temperature distribution, heat flux density, etc.

[0039] By performing thermal simulation on different fin structure variants in a virtual environment, the heat dissipation effect of each design can be fully evaluated, and the heat dissipation data obtained provides rich data support for the subsequent selection of the optimal structure.

[0040] S122, sorting the heat dissipation data corresponding to all the multi-layer fin structures, and determining the corresponding optimal heat dissipation structure set.

[0041] Among them, the heat dissipation data of all fin structure variants are sorted, including key indicators such as the highest temperature point, average temperature, temperature difference distribution, etc., and then all fin structure variants are sorted according to the key indicators of heat dissipation effect (such as maximum temperature, average temperature, etc.). According to the sorting results, the top few fin structure variants with the best heat dissipation effects can be selected to form a preferred heat dissipation structure set.

[0042] First, through sorting and selection, the fin structure with the best heat dissipation effect can be quickly identified, providing candidate solutions for subsequent practical applications; secondly, the preferred range can be narrowed down to reduce the workload and cost of subsequent practical tests.

[0043] S123, applying all the preferred heat dissipation structures in the preferred heat dissipation structure set to an actual scenario to determine an optimal heat dissipation structure.

[0044] Among them, each structural variant in the preferred heat dissipation structure set is applied to the actual transformer heat dissipation system for actual testing. The heat dissipation effect of each fin structure is monitored in the actual working environment, and the temperature distribution, heat flux density and other data during actual operation are recorded. The actual test results are compared with the virtual simulation results, the actual heat dissipation effect is analyzed, and the optimal heat dissipation structure is determined. Based on the actual test results, the fin structure with the best heat dissipation effect is finally determined to provide the most optimized design solution for actual production.

[0045] By executing steps S121 to S123, thermal simulations of different multi-layer fin structures are performed in a virtual working environment, and a preferred heat dissipation structure set is selected based on the simulation results. Finally, the preferred structure is applied to the actual scene to determine the optimal heat dissipation structure. This series of steps can ensure the reliability and effectiveness of the final design. This method not only improves the scientificity and accuracy of the heat dissipation structure design, but also verifies the feasibility of the design through actual tests, thereby significantly improving the performance and stability of the transformer heat dissipation system.

[0046] In the process of optimizing the design, the method also includes: S111, monitor the temperature data of the inside and heat dissipation structure of the target transformer in real time through a temperature sensor, and record and form a historical temperature data set.

[0047] Temperature sensors are installed at key locations of the target transformer (such as coils, cores, cooling fins, etc.). The temperature sensors continuously collect temperature data inside the target transformer and the cooling structure, and send the data to the data processing center in real time through data transmission equipment (such as wireless transmission modules). The real-time collected temperature data is recorded to form a historical temperature data set for subsequent analysis.

[0048] S112, calling a pre-trained recognition model, inputting a historical temperature data set into the recognition model for analysis, and obtaining a corresponding temperature change trend.

[0049] The recognition model training process includes the following steps: 1. Data collection: Historical data collection: Collect temperature data of the transformer under different working conditions, including internal temperature, heat dissipation structure temperature, ambient temperature, etc.; Working condition information: Record various working condition information of the transformer during operation, such as load conditions, environmental conditions (temperature, humidity, etc.), fan speed, etc.

[0050] 2. Data preprocessing: Data cleaning: remove invalid data, fill missing values, and correct outliers; Feature engineering: extract key features that affect temperature change trends, such as sliding windows and periodic features of time series data; Data standardization: standardize the data to ensure that the data is compared on the same scale.

[0051] 3. Data division: Data segmentation: Divide the data set into training set, validation set and test set, with the general ratio of 70% training set, 15% validation set and 15% test set, to ensure that the data distribution of the training set, validation set and test set is as consistent as possible.

[0052] 4. Model selection and training: Model selection: Select a model suitable for time series analysis, such as ARIMA (autoregressive integrated moving average model), LSTM (long short-term memory network), GRU (gated recurrent unit), etc.; Model initialization: Initialize model parameters, such as weights, biases, etc.; Loss function: Define loss function, such as mean square error (MSE), root mean square error (RMSE), etc.; Optimization algorithm: Select an appropriate optimization algorithm, such as Adam, RMSprop, etc.; Iterative training: Use the training set data for multiple iterative training, and update the model parameters after each iteration until the loss function converges or reaches the predetermined training rounds.

[0053] 5. Model validation and tuning: Cross-validation: Use validation set data to validate the model and evaluate the generalization ability of the model; Hyperparameter tuning: Adjust the model's hyperparameters, such as learning rate, number of hidden layers, time step, etc., based on the performance on the validation set; Performance evaluation: Use test set data to evaluate the final performance of the model.

[0054] 6. Model deployment: Model preservation: Save the trained model for subsequent use; Interface development: Develop an API interface so that the model can receive real-time temperature data and output temperature change trend predictions.

[0055] By selecting a pre-trained temperature change trend recognition model and then inputting the historical temperature data set into the recognition model, the recognition model will process and analyze the data, and the recognition model outputs a trend forecast of temperature change, including the temperature change trend in the future; through model analysis, future temperature change trends can be predicted.

[0056] S113: Adjust the heat dissipation strategy based on the temperature change trend, including but not limited to increasing the fan speed in advance or starting additional cooling measures according to the expected working conditions.

[0057] Among them, based on the analysis results of historical data, a more scientific heat dissipation strategy can be formulated, and the heat dissipation strategy can be dynamically adjusted according to the changes in actual working conditions to ensure that the transformer always operates within a safe temperature range. In addition, increase the fan speed in advance: If it is predicted that the temperature will rise in the future, the speed of the cooling fan can be increased in advance to enhance the heat dissipation effect; start additional cooling measures: If it is predicted that the temperature will rise significantly, additional cooling measures can be started, such as starting the backup cooling system or increasing the flow of the cooling medium.

[0058] It should be pointed out here that by real-time monitoring of the temperature data inside the target transformer and the heat dissipation structure, and adjusting the heat dissipation strategy based on these data, the heat dissipation effect of the transformer can be finely managed and optimized. This method can not only monitor the temperature changes of the transformer in real time, but also predict future temperature trends through the analysis of historical data, and take heat dissipation measures in advance, thereby significantly improving the operational stability and safety of the transformer.

[0059] For the key parts of the target transformer, the embodiment of the present application also includes: S114, determining the key parts corresponding to the target transformer, deploying optical fiber temperature sensors at the key parts, and forming a continuous temperature monitoring network.

[0060] Among them, fiber optic temperature sensors are installed in these key locations. Fiber optic sensors have the characteristics of high precision and strong anti-electromagnetic interference ability, and are suitable for use in the high-temperature environment inside the transformer. Multiple fiber optic temperature sensors are connected to form a continuous temperature monitoring network. By deploying sensors at key locations to form a continuous monitoring network, the temperature changes inside the transformer can be fully covered.

[0061] S115, monitor the temperature data of key parts in real time through the temperature monitoring network, and transmit the temperature data to the central control system. The central control system processes the received temperature data, forms a temperature distribution diagram, and displays it in real time on the monitoring interface.

[0062] Among them, the optical fiber temperature sensor continuously collects temperature data of key parts and sends it to the central control system in real time through data transmission equipment (such as optical fiber communication system). The central control system processes the received temperature data, including data cleaning, calibration, format conversion, etc., and the central control system generates a temperature distribution map based on the processed temperature data to display the temperature conditions of key parts of the transformer. The temperature distribution map is displayed in real time on the monitoring interface (such as large-screen display, monitoring room terminal, etc.) for operators to view at any time.

[0063] S116, retrieve the temperature threshold of each key part, detect whether there is a hot spot based on the temperature threshold and the part temperature data, and trigger an alarm if there is a hot spot.

[0064] First, according to the design specifications and operating experience of the transformer, a reasonable temperature threshold is set for each key part to ensure that the threshold will not be exceeded under normal operating conditions; the central control system detects the temperature data of each part in real time according to the set temperature threshold to determine whether there is a situation where the threshold is exceeded. Once the temperature of a part exceeds the set threshold, the system considers that an overheat point has appeared in that part. When an overheat point is detected, the central control system triggers the alarm mechanism and reminds the operator through sound and light alarms, text message notifications, etc.

[0065] In a virtual working environment, fiber optic temperature sensors are deployed at key locations of the transformer to form a continuous temperature monitoring network. The temperature data is monitored and processed in real time through a central control system, and a temperature distribution diagram is generated and displayed on the monitoring interface. Hot spots can be detected in time and alarms can be triggered by setting temperature thresholds. In the process of optimizing the heat dissipation structure design of the transformer, the heat dissipation structure can ensure the safety and stability of the transformer operation, thereby achieving the optimization efficiency of the transformer heat dissipation structure.

[0066] During the design process, when designing the corresponding heat dissipation structure, the following designs are performed on the heat dissipation structure, specifically including: S124, selecting corresponding thermoelectric materials, and determining corresponding arrangement positions in the heat dissipation structure of the target transformer.

[0067] Among them, according to the operating temperature range of the transformer and the characteristics of the heat dissipation structure, suitable thermoelectric materials are selected. Commonly used thermoelectric materials include bismuth telluride (Bi2Te3), lead selenide (PbSe), etc. These materials have high thermoelectric conversion efficiency; in the heat dissipation structure of the transformer, the optimal layout position of the thermoelectric module is determined, usually selecting an area with a larger temperature gradient, such as the side of the heat dissipation fin close to the high temperature area, so that a larger temperature difference can be formed, which is conducive to thermoelectric conversion.

[0068] S125, installing corresponding thermoelectric modules based on the arrangement position, so that one side of the thermoelectric module contacts the high temperature area and the other side contacts the low temperature area, thereby forming a temperature difference.

[0069] Among them, the thermoelectric modules are installed according to the predetermined layout positions. Make sure that one side of the thermoelectric module is in close contact with the high-temperature area (such as near the transformer coil) and the other side is in close contact with the low-temperature area (such as the outside of the heat sink fins or the cooling medium), optimize the contact between the thermoelectric module and the high-temperature area and the low-temperature area, ensure good heat conduction, and reduce heat loss.

[0070] S126, converting the temperature difference into electrical energy through a thermoelectric module, and storing the generated electrical energy.

[0071] Among them, the thermoelectric module uses the temperature difference to generate the potential difference, thereby converting thermal energy into electrical energy. This process is based on the Seebeck effect, that is, when two different materials come into contact, the temperature difference will generate voltage, and the electrical energy generated by the thermoelectric module is transmitted through the circuit to the energy storage device (such as a battery or supercapacitor) for storage. The energy storage device needs to have good charging and discharging performance to ensure the effective use of electrical energy.

[0072] By selecting appropriate thermoelectric materials and installing thermoelectric modules in the heat dissipation structure of the target transformer, the temperature difference can be converted into electrical energy and stored. This method not only takes energy utilization into consideration during the optimization design process, but also optimizes the heat dissipation effect of the transformer and reduces energy waste.

[0073] During the design process, considering the rapid temperature changes inside the transformer, in order to cope with the situation where the transformer suddenly experiences a large temperature rise in a short period of time, the PCM material is encapsulated in a container to form a heat storage unit, and the heat storage unit is integrated into the heat dissipation structure.

[0074] It should be pointed out here that the appropriate phase change material should be selected according to the temperature range and heat dissipation requirements of the transformer operation. PCM materials should have a high latent heat value, good thermal stability and chemical stability. Commonly used PCM materials include paraffin, fatty acid esters, salt hydrates, etc.

[0075] As for packaging container design, a suitable container is designed to encapsulate the PCM material. The container should have good sealing to prevent PCM leakage and should have sufficient strength to withstand the stress caused by temperature changes.

[0076] For the packaging process: put the PCM material into the designed container, ensure that the PCM material is filled evenly and leave enough expansion space to accommodate the volume change during the phase change process.

[0077] The packaged heat storage unit is installed in the designated position of the heat dissipation structure. It can be installed by bonding, embedding or fixing the bracket. It is necessary to ensure that the heat storage unit works in coordination with other parts of the heat dissipation structure, such as with the heat dissipation fins, cooling fans, etc., to form an efficient heat dissipation system.

[0078] By encapsulating PCM materials in containers to form heat storage units and integrating these heat storage units into the heat dissipation structure of the transformer, effective management of the transformer operating temperature can be achieved. This method not only improves the efficiency and stability of the heat dissipation system, but also effectively absorbs and releases heat through the phase change process of the PCM material, reduces temperature fluctuations, and improves the operating safety and service life of the transformer. Therefore, this PCM material-based heat storage unit integration solution can improve the performance of the transformer heat dissipation system.
