Description

Technical Field

[0001] The present invention belongs to the technical field of power supply heat dissipation control, and in particular relates to a heat dissipation control method and system for a new energy power supply. Background Art

[0002] With the development and application of new energy technologies, the power density of new energy power supply equipment has gradually increased. Therefore, in order to improve energy utilization efficiency and reduce heat loss, higher requirements are placed on the heat dissipation control system. New energy power supply equipment often operates under high temperature and high power conditions. Improper heat dissipation will cause the equipment to overheat and be damaged. Therefore, it is necessary to design an efficient heat dissipation system based on the characteristics of new energy power supplies to ensure the safe and reliable operation of the equipment. The research background of the heat dissipation control system of new energy power supplies is mainly to meet the heat dissipation requirements of new energy power supply equipment under high power density and high temperature working conditions, improve energy utilization efficiency, reduce energy consumption, ensure safe and stable operation of equipment and protect the environment in a friendly manner.

[0003] Nowadays, there are still some deficiencies in the research on the heat dissipation control system of new energy power sources. Specifically, the research on the multi-factor synergy of the heat dissipation control system of traditional new energy power sources is insufficient. It is limited to judging whether heat dissipation is needed based on the temperature of the new energy power source and directly controlling the heat dissipation of the new energy power source. The method of starting the heat dissipation system based on temperature judgment may lead to energy waste. The traditional heat dissipation control system based on temperature judgment often lacks comprehensive consideration of multiple factors, cannot truly exert the efficiency of the heat dissipation system, cannot adjust the working state of the heat dissipation system according to the real-time status and usage of the equipment, and cannot achieve multi-factor synergy to improve the heat dissipation efficiency. Since the heat dissipation control system based on simple temperature judgment cannot accurately control the temperature of the equipment, it may cause the equipment to overheat or overcool frequently, thereby shortening the service life of the equipment. Summary of the Invention

[0004] One of the purposes of the present invention is to provide a heat dissipation control method for a new energy power supply, which can intelligently and accurately control the heat dissipation of the new energy power supply, improve the heat dissipation efficiency, reduce maintenance costs and energy costs, and effectively extend the service life of the equipment.

[0005] A second object of the present invention is to provide a system for implementing the heat dissipation control method of the new energy power supply.

[0006] The present invention provides a method for controlling heat dissipation of a new energy power supply, comprising the following steps:

[0007] S1. Calculate the real-time temperature status of the new energy power supply based on the real-time temperature of the new energy power supply board, the real-time temperature of the housing, and the real-time temperature of the radiator, and then compare it with the preset temperature status reference value to determine whether the new energy power supply needs to be cooled. If cooling is required, proceed to the next step; otherwise, terminate the cooling control process;

[0024] The rate DV at which the chemical energy of the new energy power source is converted into electrical energy is the average discharge power of the new energy power source.

[0025] Step S3 includes the following steps:

[0026] Based on the heat dissipation structure and heat dissipation equipment status of the new energy power supply, a heat dissipation characteristic dataset of the new energy power supply is obtained; the heat dissipation characteristic dataset of the new energy power supply includes the area of ​​the heat dissipation holes of the new energy power supply, the average speed of the heat dissipation fan of the new energy power supply, and the length of the fan blades of the new energy power supply;

[0027] Based on the obtained new energy power source heat dissipation characteristic data set and the corresponding reference value, the new energy power source heat dissipation characteristic value is calculated.

[0028] Calculate the heat dissipation characteristic value of the new energy power supply using the following formula: ;

[0029] in, is the heat dissipation characteristic value of the new energy power supply; KS is the area of ​​the heat dissipation hole of the new energy power supply; ZS is the average speed of the cooling fan of the new energy power supply; SL is the length of the fan blade of the cooling fan of the new energy power supply; Define the heat dissipation hole area for the preset new energy power source; Define the speed for the preset new energy power supply cooling fan; Define the length of the fan blades for the preset new energy power supply cooling fan; To preset the compensation factor for the heat dissipation hole area of ​​the new energy power supply; It is the compensation factor for the average speed of the cooling fan of the preset new energy power supply; It is the compensation factor for the blade length of the preset new energy power supply cooling fan.

[0030] Step S4 is specifically as follows:

[0031] Based on the historical best heat dissipation solution of the new energy power source, a new energy heat dissipation model is constructed; the input of the new energy heat dissipation model is the operating characteristic value and the heat dissipation characteristic value of the new energy power source, and the output is the best heat dissipation solution of the new energy power source;

[0032] The input of the new energy heat dissipation model is the operating characteristic value and heat dissipation characteristic value of the new energy power supply, and the output is the optimal heat dissipation solution for the new energy power supply. The specific steps include:

[0033] By inputting the current new energy power source working characteristic value and the new energy power source heat dissipation characteristic value, a unique new energy power source heat dissipation solution characteristic value can be obtained through the mapping relationship set in the database;

[0034] Then, the obtained unique new energy power supply heat dissipation solution characteristic value is compared with the preset new energy power supply heat dissipation solution characteristic value interval to determine which preset new energy power supply heat dissipation solution characteristic value interval the obtained unique new energy power supply heat dissipation solution characteristic value value falls into, thereby determining the unique preset new energy power supply heat dissipation solution characteristic value interval;

[0035] The preset characteristic value interval of the new energy power supply heat dissipation solution can map a unique optimal heat dissipation solution for the new energy power supply.

[0036] The optimal heat dissipation solution is based on the current operating characteristic values ​​of the new energy power supply and the heat dissipation characteristic values ​​of the new energy power supply. It is necessary to dissipate the temperature of the new energy power supply to the average speed of the new energy power supply cooling fan and the operating time of the cooling fan within the set temperature range. Specifically:

[0039] in, It is the characteristic value of the heat dissipation solution of the new energy power supply; is the working characteristic value of the new energy power source; is the heat dissipation characteristic value of the new energy power source;

[0040] After determining the characteristic value interval of the new energy power supply heat dissipation solution, obtain the historical best heat dissipation solution corresponding to the characteristic value interval of the new energy power supply heat dissipation solution, specifically:

[0044] Wherein, t is the cooling fan operation time; c is the fan efficiency constant;

[0045] When the calculated cooling fan speed N is greater than the actual maximum cooling fan speed, the cooling fan will continue to run at the maximum fan speed until the temperature difference is detected. is 0;

[0046] The obtained cooling fan speed and cooling fan operating time are used as the historical optimal cooling solution corresponding to the cooling characteristic interval of the new energy power supply.

[0047] The present invention also provides a system for implementing the heat dissipation control method of the new energy power supply, comprising a new energy power supply heat dissipation judgment module, a new energy power supply working characteristic value calculation module, a new energy power supply heat dissipation characteristic value calculation module, a new energy power supply heat dissipation model construction module and a new energy power supply heat dissipation control module connected in series in sequence;

[0048] The new energy power supply heat dissipation judgment module calculates the real-time temperature status evaluation value of the new energy power supply based on the real-time temperature of the new energy power supply board, the real-time temperature of the shell and the real-time temperature of the radiator, and then compares it with the preset temperature status reference value to determine whether the new energy power supply needs heat dissipation. If heat dissipation is required, the module proceeds to the next step; otherwise, the heat dissipation control process is terminated and the data is uploaded to the new energy power supply working characteristic value calculation module;

[0049] The new energy power supply working characteristic value calculation module obtains a new energy power supply working characteristic data set based on the received data, the corresponding new energy power supply working state and the working environment state, and then calculates the new energy power supply working characteristic value based on the new energy power supply working characteristic data set and the corresponding reference value, and uploads the data to the new energy power supply heat dissipation characteristic value calculation module;

[0057] The present invention provides a method for controlling heat dissipation of a new energy power supply, the flow chart of which is as follows: Figure 1 As shown, the following steps are included:

[0058] S1. Calculate the real-time temperature status assessment value of the new energy power supply based on the real-time temperature of the new energy power supply board, the real-time temperature of the housing, and the real-time temperature of the heat sink, and the corresponding reference values. Compare this value with the preset temperature status reference value to determine whether the new energy power supply requires cooling. If cooling is required, proceed to the next step; otherwise, terminate the cooling control process. This includes the following steps:

[0059] Based on the real-time temperature of the new energy power supply board, the real-time temperature of the shell and the real-time temperature of the radiator, the real-time temperature status data set of the new energy power supply is obtained;

[0060] The new energy power supply real-time temperature status data set includes the new energy power supply board temperature, the new energy power supply shell temperature and the new energy power supply radiator surface temperature;

[0061] Based on the obtained new energy power source real-time temperature status data set and the corresponding reference value, the new energy power source real-time temperature status evaluation value is calculated;

[0062] The obtained new energy power supply real-time temperature status evaluation value is compared with the preset new energy power supply real-time temperature status reference value. If the new energy power supply real-time temperature status evaluation value is greater than or equal to the new energy power supply real-time temperature status reference value, it is judged that the new energy power supply corresponding to the new energy power supply real-time temperature status evaluation value needs to dissipate heat; otherwise, it is judged that the new energy power supply corresponding to the new energy power supply real-time temperature status evaluation value does not need to dissipate heat.

[0063] Specifically, the power board temperature reflects the internal working status and heat generation level of the power supply equipment. It is an important indicator for evaluating the equipment's operating stability and heat dissipation effect. When the power board temperature is too high, it may cause the equipment to overheat, be damaged or have performance degradation. The new energy power supply casing temperature refers to the temperature of the surface of the casing of the new energy power supply equipment. The casing temperature reflects the overall heat dissipation effect of the equipment and the influence of the external environment. Maintaining an appropriate casing temperature can improve the stability and service life of the equipment, and also help reduce potential safety hazards. The new energy power supply radiator surface temperature refers to the temperature of the surface of the radiator in the new energy power supply equipment. The radiator is used to dissipate the heat generated by the equipment and help achieve heat dissipation of the equipment. The radiator surface temperature can reflect the heat dissipation effect of the equipment. Excessively high radiator temperature may indicate poor heat dissipation and further heat dissipation treatment is required.

[0064] It should be noted that the above-mentioned power board is one of the main areas that generate heat in new energy power equipment. The increase in the power board temperature will cause the casing temperature to rise. The higher the power board temperature, the higher the casing temperature will be. If the power board temperature continues to be too high, the casing temperature may exceed the safe range, affecting the stability and life of the equipment. The casing temperature is closely related to the surface temperature of the radiator. The increase in casing temperature will affect the heat dissipation effect of the radiator, causing the surface temperature of the radiator to rise. If the heat dissipation effect of the radiator is poor, it may cause the equipment to overheat, thereby affecting the performance and reliability of the equipment. There is also a direct correlation between the power board temperature and the surface temperature of the radiator. The increase in the power board temperature will increase the heat dissipation load of the radiator, causing the surface temperature of the radiator to rise. Good heat dissipation effect of the radiator can effectively reduce the power board temperature and ensure stable operation of the equipment.

[0065] The above steps can monitor the temperature status of the new energy power supply in real time, understand the working status of the equipment in a timely manner, help to discover and solve potential heat dissipation problems, and compare the real-time temperature data with the preset temperature status reference value to more objectively and scientifically judge whether heat dissipation is needed, avoiding the uncertainty brought by subjective judgment. Timely monitoring and judgment of the temperature status of the new energy power supply can effectively prevent equipment failures and damage caused by overheating, improve the reliability and stability of the equipment, and perform heat dissipation operations on the equipment according to actual needs to avoid unnecessary heat dissipation consumption, save energy and reduce environmental pollution, meet the requirements of energy conservation and emission reduction, and perform heat dissipation operations in a timely manner to ensure that the new energy power supply equipment operates within an appropriate temperature range and improve the performance and work efficiency of the equipment.

[0066] Calculate the real-time temperature status evaluation value of the new energy power source using the following formula: ;

[0067] in, is the real-time temperature status evaluation value of the new energy power supply; BT is the temperature of the new energy power supply board; KT is the temperature of the new energy power supply shell; QT is the surface temperature of the new energy power supply radiator; To preset the reference temperature of the new energy power supply board; To preset the reference temperature of the new energy power supply shell; To preset the reference temperature of the surface of the new energy power radiator; It is the compensation factor of the preset new energy power board temperature; The compensation factor for the preset new energy power supply casing temperature; is the compensation factor of the preset new energy power radiator surface temperature; e is a natural constant.

[0068] Specifically, the above-mentioned real-time temperature status evaluation value of the new energy power supply is calculated through the temperature of the new energy power supply board, the temperature of the new energy power supply shell, and the surface temperature of the new energy power supply radiator. It can help operation and maintenance personnel to timely understand the working status of the equipment, discover potential temperature problems and make corresponding treatments. Overheating of electronic equipment will have a serious impact on the performance and life of the equipment, and even cause equipment failure and damage. Real-time monitoring and evaluation of temperature status can timely discover temperature anomalies and take necessary measures to prevent equipment from overheating and damage. Understanding the surface temperature of the radiator can help evaluate the heat dissipation effect, timely understand the heat dissipation of the equipment, help optimize the heat dissipation design, improve the heat dissipation efficiency of the equipment, and ensure that the equipment operates within an appropriate temperature range. Through real-time monitoring and evaluation of temperature status, the operating temperature of the equipment can be effectively controlled, the stability and reliability of the equipment can be improved, problems can be discovered and dealt with in time, the failure rate of the equipment caused by temperature problems can be reduced, the service life of the equipment can be extended, problems can also be discovered and measures can be taken in time, and the maintenance cost of the equipment caused by temperature problems can be reduced. Handling temperature anomalies in a timely manner can reduce damage to equipment and reduce the cost of repair and replacement of parts. The temperature of the new energy power supply board, the shell temperature of the new energy power supply and the surface temperature of the new energy power supply radiator are obtained by collecting temperature data in real time through the temperature sensor or other sensor module installed on the equipment. During the design and production stage of the equipment, the manufacturer sets a suitable reference temperature value according to the equipment specifications and performance and stores it in the database. The reference temperature value can be used as a standard reference for the equipment and is used to compare with the real-time temperature status evaluation value to help determine whether the heat dissipation of the equipment meets the design requirements. The set compensation factors of the new energy power supply board temperature, shell temperature and radiator surface temperature are obtained from the database. Based on historical data, a mapping set of the historically measured new energy power supply board temperature, shell temperature, radiator surface temperature and the compensation factors of the new energy power supply board temperature, shell temperature and radiator surface temperature is established to obtain the compensation factors of the new energy power supply board temperature, shell temperature and radiator surface temperature corresponding to the current new energy power supply board temperature, shell temperature and radiator surface temperature.

[0069] S2. Based on the corresponding new energy power supply operating state and operating environment state, obtain a new energy power supply operating characteristic data set, and then calculate the new energy power supply operating characteristic value based on the new energy power supply operating characteristic data set and the corresponding reference value, specifically comprising the following steps:

[0070] Based on the working state and working environment state of the new energy power source, a new energy power source working characteristic data set is obtained; the new energy power source working characteristic data set includes the average heating speed of the new energy power source, the working environment temperature of the new energy power source, and the rate at which the chemical energy of the new energy power source is converted into electrical energy;

[0071] Based on the obtained new energy power supply operating characteristic data set and the corresponding reference value, the new energy power supply operating characteristic value is calculated.

[0072] Specifically, the average heating rate of the new energy power supply indicates the speed at which the temperature of the new energy power supply rises during operation, reflecting the accumulation of heat inside the new energy power supply and the temperature rise caused by insufficient heat dissipation. If the new energy power supply heats up quickly, it may be necessary to increase heat dissipation measures to reduce the temperature and prevent the equipment from overheating; the working environment temperature of the new energy power supply indicates the ambient temperature around the new energy power supply. The ambient temperature will affect the heat dissipation effect of the new energy power supply. High ambient temperature will reduce the heat dissipation efficiency of the radiator, thereby affecting the operating temperature of the new energy power supply. It is necessary to adjust the heat dissipation strategy according to the ambient temperature to ensure that the equipment operates within a safe range; the rate at which the chemical energy of the new energy power supply is converted into electrical energy indicates the rate at which the new energy power supply is discharged. When the rate at which the chemical energy is converted into electrical energy is high, the heat generation of the new energy power supply itself will increase, causing the temperature to rise. The heat dissipation requirements of the new energy power supply are evaluated based on the rate at which the chemical energy is converted into electrical energy. , promptly perform heat dissipation treatment on the equipment to ensure stable operation of the equipment. Before starting discharge, record the initial voltage V and initial current I of the power supply, start discharge and start the timer, measure and record the voltage and current at the selected time interval (for example, every 10 minutes, every hour), and after each measurement, calculate the electric power P using the following formula: P=V×I, where V is the voltage at the time of measurement (volts) and I is the current at the time of measurement (amperes). Use the following formula to calculate the electric energy E consumed during the entire measurement time period t: E=∑(P×Δt), where Δt is the length of time between each measurement (hours or seconds, depending on the time unit). If the time interval is the same, the formula can be simplified to E=Pavg×t, where Pavg is the average electric power of all measurement points. After obtaining the total electric energy E and the total time t, the average discharge power can be calculated: Pavg=E / t, which shows the average energy released per unit time by the power supply;

[0073] It should be noted that the above-mentioned average heating rate is affected by the working environment temperature. When the ambient temperature is high, the internal temperature of the new energy power supply system will rise more easily, resulting in a faster heating rate. When the working environment temperature is high, the heat dissipation demand of the new energy power supply may increase, and additional heat dissipation measures need to be added to maintain the normal operating temperature of the equipment. The increase in the rate of chemical energy conversion into electrical energy will increase the heat generation inside the new energy power supply system, thereby accelerating the temperature rise rate. The average heating rate increases, and the rate of chemical energy conversion into electrical energy is high. The heat dissipation demand of the new energy power supply also increases accordingly, and more effective heat dissipation measures are needed to ensure the stable operation of the equipment. The increase in the working environment temperature will affect the heat dissipation effect of the new energy power supply system, especially in the process of chemical energy conversion into electrical energy, the high ambient temperature will reduce the heat dissipation efficiency of the radiator, thereby accelerating the internal temperature rise rate. Under high ambient temperature, when the rate of chemical energy conversion into electrical energy is high, the heat dissipation demand of the new energy power supply may further increase, and more effective heat dissipation measures are needed to maintain the normal temperature of the equipment.

[0074] The above steps can more accurately evaluate the heat dissipation requirements of new energy power supplies, and formulate corresponding heat dissipation plans for different working characteristic values. For situations with high average temperature rise rate, high working environment temperature, and high chemical energy conversion rate into electrical energy, more powerful heat dissipation measures can be adopted to ensure stable operation of the equipment under high load conditions. Comprehensive analysis of specific working characteristic values ​​can better understand the working status of the new energy power supply system, so as to take targeted heat dissipation measures, improve heat dissipation efficiency, and avoid excessive or insufficient heat dissipation. Based on the working characteristic values ​​of the demanded heat dissipation new energy power supply obtained through comprehensive analysis, the heat dissipation plan can be continuously optimized, and more scientific and effective heat dissipation measures can be adopted to maximize the heat dissipation effect and improve the reliability and stability of the equipment.

[0075] It should be noted that the above-mentioned acquisition of the working characteristic data set of the new energy power supply that requires heat dissipation and comprehensive analysis to obtain the working characteristic value of the new energy power supply that requires heat dissipation can more accurately predict the possible future heat dissipation needs of the equipment and achieve more precise heat dissipation control. The comprehensive analysis of the working characteristic data can take into account multiple factors, realize multi-factor coordinated heat dissipation control, improve the efficiency of the heat dissipation system and energy utilization rate, and can also accurately adjust the working state of the heat dissipation system according to the real-time status and needs of the equipment to achieve optimal heat dissipation efficiency and avoid excessive or insufficient heat dissipation. By accurately controlling the heat dissipation system, frequent overheating or overcooling of the equipment can be avoided, the service life of the new energy power supply equipment can be extended, and the maintenance cost can be reduced.

[0076] Calculate the operating characteristic value of the new energy power source using the following formula: ;

[0077] in, is the working characteristic value of the new energy power source; SV is the average heating speed of the new energy power source; HT is the working environment temperature of the new energy power source; DV is the rate at which the chemical energy of the new energy power source is converted into electrical energy; Define the speed of temperature rise for the preset renewable energy power source; To preset the reference temperature of the working environment of the new energy power supply; Defines the rate at which chemical energy of a given renewable energy source is converted into electrical energy; It is the compensation factor for the average heating speed of the preset new energy power source; To preset the temperature compensation factor of the working environment of the new energy power supply; It is a compensation factor for the rate at which chemical energy of a preset new energy power source is converted into electrical energy.

[0078] It should be explained that the above-mentioned working characteristic values ​​of new energy power sources are calculated through the average speed of heating up of new energy power sources, the working environment temperature of new energy power sources, and the rate at which chemical energy of new energy power sources is converted into electrical energy. This can better understand the heat dissipation needs of the equipment, optimize the heat dissipation design of the equipment, ensure that the equipment can effectively dissipate heat under normal working conditions, reduce the risk of excessive temperature of the equipment, and improve the stability and reliability of the equipment. It can also evaluate the energy conversion efficiency. If the rate is low, it may mean that the energy conversion efficiency is low. The energy utilization efficiency can be improved by optimizing the equipment operating parameters or upgrading the equipment technology, reducing energy consumption and improving the overall energy utilization efficiency. By monitoring the working characteristic values ​​of the heat-dissipating new energy power source, the temperature changes and energy conversion rates of the equipment can be monitored in real time. When an abnormality is detected, timely warnings can be given and measures can be taken to avoid equipment failures caused by overheating and ensure the normal operation of the equipment. Comprehensive consideration of the working characteristic values ​​of the new energy power source can manage the working status of the equipment more scientifically, reduce equipment overheating, overload, etc., help extend the service life of the equipment, and reduce equipment maintenance costs. By calculating and analyzing the working characteristic values ​​of the new energy power source that needs heat dissipation, problems existing in the operation of the equipment can be found and solved. Optimize and adjust to improve the operating efficiency of the equipment, reduce energy waste, and improve the overall performance of the equipment. Deploy temperature sensors and power conversion sensors in the new energy power supply equipment to obtain the average heating speed of the new energy power supply, the working environment temperature of the new energy power supply, and the rate at which the chemical energy of the new energy power supply is converted into electrical energy. The equipment manufacturer will provide a data table of performance parameters and characteristic values ​​of the equipment. Users can directly obtain the defined heating speed of the new energy power supply, the reference working environment temperature of the new energy power supply, and the defined rate at which the chemical energy of the new energy power supply is converted into electrical energy stored in the database from the manufacturer.

[0079] S3. Based on the new energy power source heat dissipation structure and heat dissipation device status, obtain a new energy power source heat dissipation characteristic dataset, and then calculate the new energy power source heat dissipation characteristic value based on the new energy power source heat dissipation characteristic dataset and the corresponding reference value, including the following steps:

[0080] Based on the heat dissipation structure and heat dissipation equipment status of the new energy power supply, a heat dissipation characteristic dataset of the new energy power supply is obtained; the heat dissipation characteristic dataset of the new energy power supply includes the area of ​​the heat dissipation holes of the new energy power supply, the average speed of the heat dissipation fan of the new energy power supply, and the length of the fan blades of the new energy power supply;

[0081] Based on the obtained new energy power source heat dissipation characteristic data set and the corresponding reference value, the new energy power source heat dissipation characteristic value is calculated.

[0082] Specifically, the heat dissipation hole area refers to the total area of ​​the heat dissipation holes designed on the shell of the new energy power supply equipment. By increasing the heat dissipation hole area, the contact area between the heat dissipation system and the external environment can be increased, air circulation can be promoted, and the heat dissipation effect can be accelerated. A large heat dissipation hole area usually indicates that the heat dissipation system design is more reasonable and sufficient. The average speed of the cooling fan refers to the average speed of the fan under normal working conditions. The fan can take away the hot air by rotating at high speed, which promotes the heat dissipation effect. A higher average speed usually means that the fan can dissipate heat faster, but it will also consume more energy. The length of the cooling fan blade refers to the length of the fan blade. A longer blade length usually provides a larger exhaust volume, thereby increasing air circulation, speeding up the speed at which hot air is discharged from the equipment, and improving heat dissipation efficiency.

[0083] It should be noted that the size of the above-mentioned heat dissipation hole area directly affects the contact area between the heat dissipation system and the external environment, and the heat dissipation fan removes hot air by rotating. Under normal circumstances, a larger heat dissipation hole area can provide more heat dissipation surface, which can promote air circulation, make it easier for the fan to remove heat, and improve heat dissipation efficiency. The speed of the heat dissipation fan and the length of the fan blades jointly affect the heat dissipation effect of the fan. A higher average fan speed means faster heat dissipation speed, and a longer fan blade length can provide a larger exhaust volume, so that hot air is discharged from the equipment faster. There is also a certain relationship between the area of ​​the heat dissipation hole and the length of the fan blade. Proportionally increasing the area of ​​the heat dissipation hole and the length of the fan blade can improve the heat dissipation efficiency of the overall heat dissipation system, because this not only expands the heat dissipation area, but also increases the exhaust volume, which promotes air circulation.

[0084] The above can objectively evaluate the heat dissipation performance of new energy power supplies, which helps to understand whether the heat dissipation capacity of the equipment is sufficient when working under high load, thereby ensuring the normal operation of the equipment. By analyzing the impact of the heat dissipation hole area, fan speed, and fan blade length on the heat dissipation characteristics, the optimal heat dissipation solution can be found, which helps to design a more efficient heat dissipation system and save energy costs while ensuring the heat dissipation effect. According to the obtained heat dissipation characteristic values, it can guide the selection of suitable heat dissipation equipment and heat dissipation materials. Suitable fans, heat sinks and other equipment can better play a heat dissipation role and extend the service life of the equipment. In-depth analysis of the heat dissipation characteristics of new energy power supplies can discover potential heat dissipation problems and solve them in a timely manner, which helps to improve the working efficiency and stability of the equipment.

[0085] By acquiring the new energy power supply heat dissipation characteristic data set and comprehensively analyzing the new energy power supply heat dissipation characteristic value, the heat dissipation status of the equipment can be understood more accurately and precise heat dissipation control can be achieved. For different working states and environmental conditions, the heat dissipation system can be adjusted according to the heat dissipation characteristic value to improve the heat dissipation efficiency and energy saving effect, and the heat dissipation of the equipment can be monitored to avoid negative impacts on the performance and life of the equipment. By acquiring and analyzing the heat dissipation characteristic value, an intelligent heat dissipation control system can be realized, which can be automatically adjusted according to the actual situation of the equipment, reducing manual intervention and improving the intelligence and automation level of the system operation.

[0086] Calculate the heat dissipation characteristic value of the new energy power supply using the following formula: ;

[0087] in, is the heat dissipation characteristic value of the new energy power supply; KS is the area of ​​the heat dissipation hole of the new energy power supply; ZS is the average speed of the cooling fan of the new energy power supply; SL is the length of the fan blade of the cooling fan of the new energy power supply; Define the heat dissipation hole area for the preset new energy power source; Define the speed for the preset new energy power supply cooling fan; Define the length of the fan blades for the preset new energy power supply cooling fan; To preset the compensation factor for the heat dissipation hole area of ​​the new energy power supply; It is the compensation factor for the average speed of the cooling fan of the preset new energy power supply; It is the compensation factor for the blade length of the preset new energy power supply cooling fan.

[0088] The above-mentioned heat dissipation characteristic values ​​of new energy power supply are calculated through the area of ​​the heat dissipation holes of the new energy power supply, the average speed of the heat dissipation fan of the new energy power supply, and the length of the fan blades of the heat dissipation fan of the new energy power supply. This can better understand the heat dissipation of the new energy power supply equipment, thereby optimizing the heat dissipation design, ensuring that the equipment can effectively dissipate heat, and improve the stability and reliability of the equipment. Comprehensive consideration of parameters such as the heat dissipation hole area, fan speed and fan blade length can effectively improve the working efficiency of the cooling fan, promote faster dissipation of the heat generated by the equipment, and avoid equipment failure caused by overheating. The design of the heat dissipation system can be optimized, the heat dissipation efficiency can be improved, and energy consumption can be reduced, thereby saving energy costs. Effective heat dissipation design can reduce equipment temperature, reduce thermal stress, extend the life of the equipment, and reduce maintenance costs. Optimizing the heat dissipation design and improving the heat dissipation efficiency can help the equipment maintain better stable operation in high temperature environments and improve the performance of the equipment. The means of obtaining the heat dissipation hole area can be obtained through equipment design drawings, actual measurement of the heat dissipation hole area on the equipment casing, etc. The preset new energy The power supply heat dissipation hole area is obtained through the technical parameters provided by the equipment manufacturer, the average speed of the cooling fan can be obtained by using a sensor to monitor the fan speed in real time, the preset new energy power supply cooling fan speed is obtained from the technical parameters provided by the equipment manufacturer, the cooling fan blade length can be obtained by measuring the actual fan blade length, the preset new energy power supply cooling fan blade length is obtained from the technical parameters provided by the equipment manufacturer, and the set new energy power supply heat dissipation hole area, cooling fan average speed, and cooling fan blade length compensation factors are obtained from the database. Based on historical data, a mapping set of historically measured new energy power supply heat dissipation hole area, cooling fan average speed, cooling fan blade length and new energy power supply heat dissipation hole area, cooling fan average speed, and cooling fan blade length compensation factors is established to obtain the compensation factors of the new energy power supply heat dissipation hole area, cooling fan average speed, and cooling fan blade length corresponding to the current new energy power supply heat dissipation hole area, cooling fan average speed, and cooling fan blade length.

[0089] S4. Build a new energy cooling model based on the historically optimal cooling solutions for new energy power sources. Specifically:

[0090] Based on the historical best heat dissipation solution of the new energy power source, a new energy heat dissipation model is constructed; the input of the new energy heat dissipation model is the operating characteristic value and the heat dissipation characteristic value of the new energy power source, and the output is the best heat dissipation solution of the new energy power source;

[0091] The input of the new energy heat dissipation model is the operating characteristic value and heat dissipation characteristic value of the new energy power supply, and the output is the optimal heat dissipation solution for the new energy power supply. The specific steps include:

[0092] By inputting the current new energy power source working characteristic value and the new energy power source heat dissipation characteristic value, a unique new energy power source heat dissipation solution characteristic value can be obtained through the mapping relationship set in the database;

[0093] Then, the obtained unique new energy power supply heat dissipation solution characteristic value is compared with the preset new energy power supply heat dissipation solution characteristic value interval to determine which preset new energy power supply heat dissipation solution characteristic value interval the obtained unique new energy power supply heat dissipation solution characteristic value value falls into, thereby determining the unique preset new energy power supply heat dissipation solution characteristic value interval;

[0094] The preset characteristic value interval of the new energy power supply heat dissipation solution can map a unique optimal heat dissipation solution for the new energy power supply.

[0095] The optimal heat dissipation solution is based on the current operating characteristic values ​​of the new energy power supply and the heat dissipation characteristic values ​​of the new energy power supply. It is necessary to dissipate the temperature of the new energy power supply to the average speed of the new energy power supply cooling fan and the operating time of the cooling fan within the set temperature range. Specifically:

[0096] The preset characteristic value interval of the new energy power heat dissipation solution is [0, 1], (1, 2], (2, 3], (3, 4], (4, 5]... If the characteristic value of the new energy power heat dissipation solution is 5, then the characteristic value interval of the new energy power heat dissipation solution corresponding to the characteristic value of the new energy power heat dissipation solution is (4, 5]. The historical best heat dissipation solution corresponding to the characteristic value interval of the new energy power heat dissipation solution can be obtained as the best heat dissipation solution for the new energy power supply. It should be emphasized that both ends of the first interval are closed, and all subsequent intervals are left open and right closed.

[0097] It should be noted that the inclusion of the actual working characteristic values ​​and heat dissipation characteristic values ​​of the new energy power supply in the comparison analysis can obtain a more personalized and targeted heat dissipation solution, which helps to ensure that the new energy power supply can obtain effective heat dissipation support in actual operation and improve the operating efficiency and stability of the equipment. The new heat dissipation characteristic values ​​are compared with the heat dissipation solutions stored in the database to achieve real-time adjustment and optimization. When the working characteristics or environmental conditions of the equipment change, the heat dissipation solution can be updated in time to ensure that the heat dissipation effect of the equipment is always in the best state. The comparison analysis based on the actual characteristic values ​​can more effectively match the appropriate heat dissipation solution to avoid over-design or under-design, help reduce unnecessary energy loss, improve energy utilization efficiency, and compare with the heat dissipation solutions stored in the database to respond to the heat dissipation needs of the new energy power supply in a timely manner, quickly determine the appropriate heat dissipation solution, and help to make corresponding adjustments quickly when the heat dissipation needs of the equipment change.

[0098] Calculate the characteristic value of the new energy power supply cooling solution using the following formula: ;

[0099] in, It is the characteristic value of the heat dissipation solution of the new energy power supply; is the working characteristic value of the new energy power source; is the heat dissipation characteristic value of the new energy power source;

[0100] After determining the characteristic value interval of the new energy power supply heat dissipation solution, obtain the historical best heat dissipation solution corresponding to the characteristic value interval of the new energy power supply heat dissipation solution, specifically:

[0101] Calculate the cooling fan speed using the following formula: ;

[0102] Wherein, N is the speed of the cooling fan; k is the median value of the interval of characteristic values ​​of the new energy power supply cooling solution corresponding to the characteristic value of the new energy power supply cooling solution; is the temperature difference, and ; is the target temperature;

[0103] Calculate the cooling fan operating time using the following formula: ;

[0104] Wherein, t is the cooling fan operation time; c is the fan efficiency constant;

[0105] When the calculated cooling fan speed N is greater than the actual maximum cooling fan speed, the cooling fan will continue to run at the maximum fan speed until the temperature difference is detected. is 0;

[0106] The obtained cooling fan speed and cooling fan operating time are used as the historical optimal cooling solution corresponding to the cooling characteristic interval of the new energy power supply.

[0107] By importing the new energy power supply working characteristic values ​​and the new energy power supply heat dissipation characteristic values ​​into the new energy power supply heat dissipation model and comparing them to obtain the new energy power supply heat dissipation solution, the best heat dissipation solution can be selected according to the actual working status and heat dissipation requirements of the equipment, ensuring that the equipment can maintain an appropriate temperature under different working conditions and maximize the heat dissipation effect. Through precise heat dissipation solution design, excessive or insufficient heat dissipation can be avoided, the energy efficiency performance of the heat dissipation system can be improved, which helps to reduce energy consumption, save energy costs, and improve the overall energy-saving performance of the equipment. The use of a heat dissipation solution that has been compared and optimized can effectively prevent equipment failure and damage caused by overheating.

[0108] like Figure 3As shown, the image of the change of the characteristic value of the new energy power supply heat dissipation solution as the new energy power supply heat dissipation characteristic value is shown, where the x-axis represents the new energy power supply heat dissipation characteristic value, and the y-axis represents the new energy power supply heat dissipation solution characteristic value. This can help us intuitively understand how the new energy power supply heat dissipation characteristic value affects the new energy power supply heat dissipation solution characteristic value. The larger the new energy power supply heat dissipation characteristic value, the smaller the new energy power supply heat dissipation solution characteristic value. As the new energy power supply heat dissipation characteristic value increases, the influence of the new energy power supply heat dissipation characteristic value on the new energy power supply heat dissipation solution characteristic value gradually weakens. Set the new energy power supply working characteristic value to 5, and only change the size of the new energy power supply heat dissipation characteristic value. Example values ​​of the new energy power supply heat dissipation characteristic value are shown in Table 1:
