[0002] In the development and application of hydrogen fuel cell technology, heat dissipation has always been one of the key factors affecting its performance and life. Hydrogen fuel cells generate a lot of heat during operation. If the heat cannot be dissipated in a timely and effective manner, the battery temperature will rise, which will in turn affect the battery's working efficiency, stability and service life. Therefore, the research and development of heat dissipation technology is of great significance to the commercial application of hydrogen fuel cells.

[0003] At present, the heat dissipation method of hydrogen fuel cells is to introduce cold air from the outside at the air inlet, and then use the fan to rotate the blades to generate airflow, forcing the air to flow in the fuel cell system.

However, the heat dissipation efficiency of the battery is not good by simply running the fan. In addition, in order to maintain the heat dissipation effect, the fan may need to run at a higher speed, which not only leads to increased energy consumption, but also increases the noise of the high-speed fan.

[0040] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] At present, the heat dissipation method of air-cooled hydrogen fuel cells mainly focuses on the front air inlet or the overall heat dissipation design. This method introduces external cooling air into the air inlet of the hydrogen fuel cell, and uses the convection of air to take away the heat generated by the battery, thereby achieving the purpose of heat dissipation. However, the design of the front air inlet often only considers the inflow of air, but ignores the flow path of air inside the battery and the heat dissipation efficiency. In actual applications, hot air is discharged through the air outlet to maintain the temperature balance inside the system. If the air outlet size is too small, the heat may not be discharged in time, thereby reducing the heat dissipation efficiency; if the air outlet size is too large, the air flow rate may decrease, because the larger air outlet allows more air to flow out at the same time, but the power provided by the fan may not be enough to make all the air flow out at a high speed, which reduces the heat dissipation efficiency. To this end, the present invention provides a method that can effectively improve the heat dissipation efficiency of the battery, Figure 1 This is a flow chart of the heat dissipation method of the air-cooled hydrogen fuel cell of this application, such as Figure 1 As shown, the method specifically comprises the following steps:

[0042] Step 101: Obtain the current temperature of the battery module and the current air volume at the air outlet in real time.

[0043] Specifically, temperature sensors are distributed on the battery module, and the current temperature of the battery module is collected in real time through the temperature sensors. At the same time, an air volume sensor is set at the air outlet of the battery module, and the air volume at the air outlet is detected in real time through the air volume sensor. These sensors transmit the collected data to the central controller, so that the central controller can analyze the data and adopt corresponding strategies.

[0044] Step 102: Input the current temperature and the current air volume into a blade opening prediction model, and predict the fan speed of the battery module and the blade opening at the air outlet according to the model.

[0045] Specifically, the temperature of the battery surface is an important indicator of the internal thermal state of the battery. By detecting the temperature of the battery surface, the thermal load of the battery can be understood in real time. When the battery temperature is too high, the heat dissipation needs to be increased to prevent the battery from overheating; when the battery temperature is moderate or low, the heat dissipation can be reduced to save energy.

[0046] The air volume at the air outlet directly reflects the air circulation capacity of the cooling system. By detecting the air volume, you can determine whether the cooling system is in normal working condition. If the air volume is too small, it may mean that there is a blockage or fan failure in the cooling system, and timely maintenance is required.

[0047] The blade opening is a key factor affecting the air flow of the cooling system. By adjusting the blade opening, the amount of air entering the cooling system can be controlled, thereby achieving precise control of the cooling efficiency. When the battery temperature is high, increasing the blade opening can increase the air flow and improve the cooling efficiency; when the battery temperature is moderate or low, the blade opening can be appropriately reduced to reduce energy consumption. The present application intelligently controls the blade opening according to the real-time detected temperature and air volume data to achieve the best cooling effect. Moreover, the heat generation and distribution of air-cooled hydrogen fuel cells may be different under different working environments and conditions. When the heat generation is small, the air outlet can be appropriately reduced to avoid excessive heat dissipation and energy loss; when the heat is concentrated or generated more, the air outlet can be increased to ensure that the heat is discharged in time. Therefore, by reasonably adjusting the blade opening at the air outlet, the air volume at the air outlet can be adjusted, so that the cooling airflow flows more evenly through the battery surface, reducing the phenomenon of local overheating or uneven heat dissipation, thereby improving the heat dissipation efficiency.

[0048] In addition, when the battery is under high load or running for a long time, the fuel cell may generate a lot of heat. Within a certain temperature range, as the temperature increases, the rate of chemical reaction inside the fuel cell will accelerate, and the heat generated will also increase. In order to maintain the fuel cell within a suitable operating temperature range, the fan needs to consume a certain amount of energy to drive the air flow for heat dissipation. As the temperature rises, the fan may need to run at a higher speed, resulting in increased energy consumption; at the same time, a high-speed fan will also increase noise. If the temperature of the battery is appropriate, there is no need for an excessively high fan speed for heat dissipation, so reducing the fan speed can reduce energy consumption and noise. Therefore, the present application detects the current temperature of the battery and can adjust the fan speed in time according to the current temperature, thereby effectively reducing the fan's energy consumption and noise.

[0049] In summary, this application uses a blade opening prediction model to use real-time data detected by a temperature sensor and an air volume sensor as the input of the model to predict the fan speed of the battery module and the blade opening at the air outlet. By changing the fan speed and the opening of the air outlet, the air volume flowing through the battery module can be adjusted, thereby achieving control of the air volume. Among them, the blade opening prediction model is integrated in the central controller.

[0050] Step 103: dissipate heat for the air-cooled hydrogen fuel cell based on the fan speed and blade opening.

[0051] The heat dissipation method for an air-cooled hydrogen fuel cell provided by the present invention utilizes temperature data and air volume data collected in real time as inputs of a model to predict the fan speed of a battery module and the blade opening at an air outlet, and dissipates heat for the air-cooled hydrogen fuel cell based on the fan speed and the blade opening, which can not only improve the heat dissipation efficiency but also reduce noise and energy consumption.

[0052] Furthermore, the construction of the above blade opening prediction model includes the following schemes:

[0053] First, obtain multiple historical temperature data corresponding to the battery module and the historical air volume data corresponding to each historical temperature data; then, compare each historical temperature data with the preset temperature threshold, and determine the required air volume at the air outlet based on the comparison result; then, determine the air volume difference based on the required air volume at the air outlet and the corresponding historical air volume data; finally, determine the fan speed of the battery module and the blade opening at the air outlet based on the air volume difference.

[0054] Specifically, the multiple historical temperature data and the historical air volume data corresponding to each historical temperature data are used as the data set for model training, and the data set is divided into a training set, a validation set, and a test set. The training set is used to build the initial model, and the validation set is used to calibrate the parameters of the model; the test set is used to evaluate the final performance of the model, thereby obtaining the final constructed blade opening prediction model. Among them, the process of using the training set to build the initial blade opening prediction model is: compare each historical temperature data with the preset temperature threshold, and determine the required air volume at the air outlet based on the comparison result; then, determine the air volume difference based on the required air volume at the air outlet and the corresponding historical air volume data; finally, determine the fan speed of the battery module and the blade opening at the air outlet based on the air volume difference.

[0055] The model constructed in this application can more accurately understand the heat dissipation requirements of the battery at different temperatures by obtaining multiple groups of historical temperature data and corresponding historical air volume data of the battery module. By comparing the historical temperature data with the preset temperature threshold, the required air volume at the air outlet can be determined, thereby achieving precise control of the heat dissipation efficiency. This precise control helps to avoid excessive or insufficient heat dissipation and improve heat dissipation efficiency. Moreover, the blade opening prediction model constructed in this application can reflect the gap between the actual air volume and the required air volume by calculating the air volume difference. According to this gap, the blade opening and fan speed can be adjusted to optimize energy utilization. When the actual air volume is greater than the required air volume, the blade opening can be appropriately reduced or the fan speed can be reduced to reduce energy consumption; conversely, when the actual air volume is less than the required air volume, the blade opening is increased or the fan speed is increased to meet the heat dissipation requirements. This dynamic adjustment helps to maximize the utilization of energy.

[0056] In addition, the present application helps to keep the battery within a suitable operating temperature range by precisely controlling the heat dissipation efficiency and optimizing energy utilization. Suitable operating temperature can reduce the thermal stress of the battery, reduce the aging rate of the battery, and thus extend the service life of the battery.

[0057] The heat dissipation method of the air-cooled hydrogen fuel cell provided by the present invention constructs a blade opening prediction model by combining temperature detection and air volume detection, so that the constructed model can automatically adjust the blade opening and fan speed according to the real-time detection data without manual intervention. This intelligent management not only improves the heat dissipation efficiency, but also extends the battery life and reduces the operation and maintenance costs. Moreover, since the model is built based on historical data, it can adapt to the heat dissipation requirements of batteries of different models and under different working conditions. By continuously learning and optimizing model parameters, the heat dissipation efficiency and battery life can be further improved.

[0058] Furthermore, the following describes in detail how to compare each historical temperature data with the preset temperature threshold to determine the required air volume at the air outlet:

[0059] When the difference between the historical temperature data and the preset temperature threshold is greater than or equal to the first threshold, the preset rule is used to determine that the air volume required at the air outlet is the first exhaust air volume; when the difference between the historical temperature data and the preset temperature threshold is less than the first threshold and greater than or equal to the second threshold, the preset rule is used to determine that the air volume required at the air outlet is the second exhaust air volume; when the difference between the historical temperature data and the preset temperature threshold is less than the second threshold, the preset rule is used to determine that the air volume required at the air outlet is the third exhaust air volume; wherein the first threshold is greater than the second threshold.

[0060] Specifically, the embodiment of the present application divides the comparison results into three types, namely high temperature, normal temperature and low temperature. Among them, high temperature corresponds to the first exhaust air volume; normal temperature corresponds to the second exhaust air volume, and low temperature corresponds to the third exhaust air volume. Under high temperature conditions, the battery temperature is quickly reduced by increasing the air volume (first exhaust air volume); under low temperature or normal conditions, the air volume is reduced (third exhaust air volume or second exhaust air volume), and a smaller air volume can be used to meet the heat dissipation requirements, avoiding unnecessary energy waste. This hierarchical control method can more accurately match the heat dissipation requirements of the battery, which not only improves the heat dissipation efficiency, but also reduces energy consumption and noise.

[0061] It should be noted that: this application does not limit the classification types of comparison results, which can be greater than 3 types or less than 3 types, depending on the actual situation of the battery, as long as it can reduce energy consumption and noise while improving heat dissipation efficiency.

[0062] Furthermore, there are multiple local areas distributed in the battery module; the multiple sets of historical temperature data include: multiple sets of historical temperature data corresponding to each local area. The present application compares each historical temperature data of each local area with a preset temperature threshold, and determines the required air volume at the air outlet of each local area according to the comparison result.

[0063] Specifically, during the operation of the battery module, local overheating may occur due to factors such as uneven current distribution, internal resistance differences, or external environmental influences. Local overheating will not only cause battery performance to deteriorate, but may also accelerate battery aging and even cause safety issues such as thermal runaway and fire. In order to avoid local overheating of the battery, the embodiment of the present application divides the battery module into multiple local areas, and sets a temperature sensor in each area. The temperature of the corresponding area is detected by the temperature sensor in each local area, so that fine adjustments can be made to the temperature differences in different local areas, and the local heat can be dissipated in time, effectively preventing the occurrence of local overheating of the battery.

[0064] The heat dissipation method of the air-cooled hydrogen fuel cell provided in the present application is to determine the required air volume at the air outlet of each local area by distributing multiple local areas on the battery module and comparing the historical temperature data of each local area with the preset temperature threshold. This precise monitoring realizes accurate heat dissipation of each local area, avoiding the disadvantage of "one size fits all" in the traditional heat dissipation method, that is, regardless of the temperature distribution inside the battery module, the same heat dissipation strategy is adopted, resulting in poor heat dissipation effect or energy waste. In addition, precise adjustment avoids unnecessary waste of air volume and reduces the energy loss of heat dissipation equipment such as fans. While meeting the heat dissipation requirements, the energy consumption of the entire air-cooled hydrogen fuel cell system is further reduced, and the energy utilization rate is improved.

[0065] Furthermore, multiple local areas are evenly distributed around the battery module and on the top and bottom, and corresponding blades are provided in each local area. The present application determines the corresponding opening of the blades at the air outlet of each local area according to the required air volume at the air outlet of each local area.

[0066] Specifically, the embodiment of the present application has multiple local areas evenly distributed around the battery module and at the top and bottom, and an independent air outlet and blade adjustment mechanism are set in each local area, and the blade opening is adjusted by the blade adjustment mechanism. For example: In this embodiment, it is assumed that the battery module is rectangular, and the length and width are L and W respectively. The air outlets are evenly distributed around the battery module, and N air outlets are set on each side, a total of 4N air outlets, and 4N blades are set accordingly; M air outlets are also set on the top of the battery module, and M blades are set accordingly. The present application can independently adjust the air volume of the corresponding air outlet according to the temperature difference in each local area to ensure that each area can get proper heat dissipation. This partition adjustment strategy helps to avoid the occurrence of local overheating and improve the heat dissipation efficiency and battery performance. Moreover, by different blade openings, the airflow distribution is optimized, so that the air can flow through the battery module more evenly, further improving the heat dissipation effect. At the same time, this design can also reduce the dead corners and eddies of the airflow inside the battery module, further reduce the temperature gradient, and improve the uniformity of heat dissipation.

[0067] The heat dissipation method of the air-cooled hydrogen fuel cell provided by the present invention can create a more stable temperature environment for the hydrogen fuel cell through effective air outlet adjustment. Temperature stability is crucial to the stability of the chemical reaction inside the battery, reducing battery material aging and performance degradation caused by temperature fluctuations, thereby extending the service life of the battery. Moreover, through the partition adjustment design, local heat can be dissipated in time to protect the integrity and safety of the battery.

[0068] Furthermore, each historical temperature data recorded in step 101 includes: the temperature data of the battery itself and the external environment data of the environment in which the battery is located. The present application obtains fused temperature data by weighted fusion of the temperature data of the battery itself and the external environment data; and compares the fused temperature data with a preset temperature threshold to determine the required air volume at the air outlet.

[0069] Specifically, the temperature data recorded in the embodiment of the present invention includes two parts: the temperature data of the battery itself and the external environment data of the environment in which the battery is located. Among them, the temperature data of the battery itself is used to characterize the temperature of the battery itself; and the external environment data is used to characterize the environment in which the battery is located. The external environment data is collected by environmental sensors, which can be sensors that can monitor changes in the external environment (such as temperature, humidity, and air pressure) in real time, and feed back the data information collected by these temperature, humidity, and air pressure sensors to the heat dissipation system. The system automatically adjusts the blade opening and fan speed according to this feedback information to adapt to different heat dissipation requirements.

[0070] Changes in external environmental factors may cause thermal stress inside the battery, thus affecting the performance and life of the battery. By considering these external environmental factors and taking corresponding heat dissipation measures, the damage to the battery caused by thermal stress can be effectively reduced. And the heat dissipation method combined with external environmental factors can adjust the heat dissipation power consumption according to actual needs. When high-intensity heat dissipation is not required, the system can automatically reduce power consumption, thereby reducing energy consumption and operating costs.

[0071] The heat dissipation method for an air-cooled hydrogen fuel cell provided by the present invention performs weighted fusion of the external environmental data of the battery's environment with the battery's own temperature data, and uses the fused temperature data to determine the required air volume at the air outlet. This not only helps to improve the heat dissipation efficiency and extend the battery life, but also enhances the reliability and safety of the system and reduces energy consumption and costs.
