[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application. In addition, it should be understood that the specific implementation methods described herein are only used to illustrate and explain the present application, and are not used to limit the present application.

[0028] It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments of the present application. In addition, in the following embodiments, the description of each embodiment has its own emphasis, and for parts not described in detail in one embodiment, reference can be made to the relevant description of other embodiments.

[0029] The method steps described in the embodiments of the present invention may be executed in the order described in the specific implementation manner, or the execution order of each step may be adjusted according to actual needs and on the premise that the technical problem can be solved, which will not be listed here one by one.

[0030] The cooling module is a key component in the automotive thermal management system. It is mainly used to regulate and control the temperature of core components such as the vehicle engine or battery to ensure that they operate within an appropriate temperature range. The cooling module usually includes components such as a radiator, a condenser, and a fan. It is installed behind the front air intake grille and guides external air through the radiator to remove heat, thereby achieving heat dissipation for the engine or battery. For electric vehicles, the role of the cooling module is particularly important. It can effectively prevent battery overheating and extend battery life, while improving the energy efficiency and safety of the system.

[0031] Pure electric vehicles have a smaller front grille opening. In order to reduce air leakage and increase the air flow through the cooling module, the OEM usually uses a fully sealed air deflector with good sealing performance. The cooling module air deflector can reduce the leakage of the front grille cooling airflow and increase the air intake of the cooling module.

[0032] The air deflector of the cooling module is an air guide device installed around the cooling module and connected to the front air intake grille of the car. Its main function is to guide and concentrate the airflow so that it can effectively flow to the radiator, condenser and other components of the cooling module to improve the cooling effect. The air deflector usually adopts a sealed design to reduce the leakage and turbulence of the airflow around the cooling module, thereby improving the air intake efficiency and enabling the cooling module to more efficiently remove the heat from the system. For electric vehicles, the air deflector can dynamically adjust the airflow path at different vehicle speeds and wind speeds to ensure the temperature uniformity and heat dissipation performance of the cooling module under various driving conditions, thereby extending the service life of key components.

[0033] The fully sealed air duct has different shapes and different air guiding effects. Usually, the OEM will lock in a cooling module air duct structure with better air guiding, but the airflow direction varies at different vehicle speeds and wind speeds, which results in different uniformity of the cooling module at different vehicle speeds and wind speeds. The same air duct cannot meet the requirement of uniform air intake for the cooling module at different vehicle speeds.

[0034] Based on the above technology, refer to Figure 1 An embodiment of the present invention provides a deflector cover, including a deformable deflector cover body, wherein the deflector cover body has at least one variable curvature segment, and the curvature of the variable curvature segment can be adjusted according to the temperature distribution of the cooling module to change the airflow direction and optimize the air intake uniformity of the cooling module.

[0035] The air deflector includes a deformable air deflector body. In some embodiments, the air deflector body has a plurality of curvature variable sections. For example, the air deflector body may include a first curvature variable section located at a lower portion and a second curvature variable section located at an upper portion. The curvatures of the first curvature variable section and the second curvature variable section may be independently adjusted to achieve precise control of the airflow direction.

[0036] In some cases, the first variable curvature segment may correspond to Figure 1 When the curvature of the first variable curvature segment is large, the airflow will leave the ab segment and blow vertically toward the lower part of the cooling module. On the contrary, when the curvature of the first variable curvature segment is small, the airflow will flow along the wall of the ab segment.

[0037] The second variable curvature segment may correspond to Figure 1 In some embodiments, when the airflow at the top of the cooling module is large, the curvature of the second variable curvature segment can be recessed toward the inside of the air guide cover to reduce the airflow at the top. When the airflow at the top of the cooling module is insufficient, the curvature of the first variable curvature segment can be reduced to allow the airflow to flow close to the air guide cover, and the second variable curvature segment can be convex outside the air guide cover to increase the flow area at the top, thereby increasing the air intake.

[0038] The curvature-variable section of the air deflector can be adjusted in a variety of ways. For example, the curvature-variable section may include a retractable structure, a bendable material, or be composed of a plurality of relatively movable small sections. In some cases, the curvature-variable section can be adjusted by an electric mechanism, a hydraulic mechanism, or a pneumatic mechanism.

[0039] Based on the above air guide cover, an embodiment of the present invention further provides a cooling module.

[0040] The cooling module includes a cooling module body, a plurality of temperature sensors disposed on the cooling module body, and the air guide cover described in any of the above embodiments. The plurality of temperature sensors can be used to detect the temperature of different areas of the cooling module. The air guide cover can adjust the curvature of its variable curvature section according to the detection results of the temperature sensors.

[0041] In some embodiments, the cooling module body includes components such as a radiator and a condenser. A plurality of temperature sensors may be arranged at different positions of the cooling module body. For example, the temperature sensors may be arranged at the upper part, the middle part, and the lower part of the cooling module body, respectively. Figure 1 and 2 The upper temperature sensor T1, the middle temperature sensor T2 and the lower temperature sensor T3 can be used to measure the temperatures of the upper, middle and lower parts of the cooling module respectively.

[0042] The temperature sensor may be of various types, such as a thermocouple, a thermistor, an infrared temperature sensor, etc. In some cases, the temperature sensor may be connected to a thermal management control system to transmit the detected temperature data to the thermal management control system.

[0043] The air guide cover can adjust the curvature of its variable curvature section according to the temperature distribution detected by the temperature sensor. For example, when it is detected that the temperature of the upper part of the cooling module is higher than the temperature of the middle and lower parts, the air guide cover can reduce the curvature of the first variable curvature section, and control the second variable curvature section to bulge toward the outer side of the air guide cover to increase the upper flow area, thereby increasing the intake volume. Conversely, when it is detected that the temperature of the lower part of the cooling module is higher than the temperature of the middle and upper parts, the air guide cover can increase the curvature of the first variable curvature section to increase the airflow volume of the lower part of the cooling module.

[0044] In some embodiments, the curvature adjustment of the air duct may be controlled by a thermal management control system, which may calculate the optimal air duct curvature configuration according to the detection result of the temperature sensor and send a control signal to the curvature adjustment mechanism of the air duct.

[0045] In this way, the cooling module can dynamically adjust the uniformity of the air entering the cooling module, thereby improving the cooling efficiency. In some cases, this dynamic adjustment can adapt to different driving conditions and environmental conditions, such as changes in vehicle speed and ambient temperature.

[0046] The cooling module described in the embodiment of the present invention can achieve temperature balance and efficient heat dissipation, and has significant technical effects such as precise temperature control, dynamic airflow adjustment, energy saving and consumption reduction, adaptability to multiple working conditions, and improved system stability, which greatly improves the overall performance and service life of the electric vehicle cooling system.

[0047] Reference Figure 3 The embodiment of the present invention further provides a method for controlling a shroud, comprising: S1, detect the temperature of different areas of the cooling module; S2, judging the uniformity of the air entering the cooling module according to the temperature; S3, based on the Coanda effect, adjust the curvature of the variable curvature section of the air guide cover to control the direction of the front air intake so that the airflow impacts the cooling module more evenly.

[0048] Specifically, first, the temperature data of different areas of the cooling module are detected in real time through the temperature sensor (S1), and the temperature information of the upper, middle and lower parts (such as T1, T2, T3) is transmitted to the vehicle thermal management control system. Then, the control system judges the uniformity of the air intake of the cooling module according to these temperature values ​​(S2), analyzes whether there are areas with local high temperatures, and thus determines whether the airflow distribution meets the cooling requirements. Finally, based on the Coanda effect (S3), the curvature of the variable curvature segment of the air deflector is dynamically adjusted, and the airflow is guided to the area with higher temperature by adjusting the first variable curvature segment (ab segment) and the second variable curvature segment (cd segment), so that the airflow impacts the cooling module more evenly to optimize the heat dissipation effect. Specifically, when it is detected that the upper temperature is high, the curvature of the ab segment is reduced, so that the airflow adheres to the surface of the air deflector and flows to the upper part; when the lower temperature is high, the curvature of the ab segment is increased to guide the airflow to the lower area of ​​the cooling module. In this way, the dynamic adjustment of the curvature of the air deflector achieves temperature balance and efficient heat dissipation of the cooling module.

[0049] By detecting the temperature of different areas of the cooling module, judging the uniformity of the air intake, and dynamically adjusting the curvature of the air deflector based on the Coanda effect to optimize the airflow guidance, the cooling module can achieve uniform heat dissipation under different vehicle speed and wind speed conditions. Unlike the fixed air deflector structure used in the prior art, this method can automatically adjust the shape of the air deflector according to real-time temperature feedback, so that the airflow impacts the cooling module more evenly, thereby significantly improving the cooling efficiency and thermal management effect.

[0050] The embodiment of the present invention also provides a method for controlling a shroud. In some cases, the method may include detecting the temperature of different areas of the cooling module. For example, an upper temperature sensor T1, a middle temperature sensor T2, and a lower temperature sensor T3 may be used to detect the temperature of the upper, middle, and lower parts of the cooling module, respectively. These temperature sensors may transmit the detected temperature data to a thermal management control system.

[0051] In some embodiments, the air deflector control can determine the uniformity of the air entering the cooling module based on the detected temperature. The thermal management control system can analyze the temperature differences in different areas to determine the airflow distribution of each part of the cooling module. For example, if the temperature detected by the upper temperature sensor T1 is significantly higher than the temperatures detected by the middle temperature sensor T2 and the lower temperature sensor T3, it may indicate that the airflow in the upper part of the cooling module is insufficient.

[0052] Based on this judgment, the air deflector control method can adjust the curvature of the variable curvature section of the air deflector to control the direction of the front air intake so that the airflow impacts the cooling module more evenly. This adjustment can be based on the Coanda effect principle. In some cases, when it is detected that the temperature of the upper part of the cooling module is high, the curvature of the first variable curvature section can be reduced to make it easier for the airflow to adhere to the surface of the air deflector and flow upward. At the same time, the second variable curvature section can be controlled to bulge toward the outside of the air deflector to increase the upper flow area, thereby increasing the air intake. On the contrary, when it is detected that the temperature of the lower part of the cooling module is high, the curvature of the first variable curvature section can be increased to reduce the upper airflow and increase the lower airflow.

[0053] In some embodiments, the curvature adjustment of the air duct may be a continuous and gradual process, and the curvature of the air duct may be continuously fine-tuned according to the real-time feedback from the temperature sensor to achieve the best cooling effect.

[0054] In some embodiments, detecting the temperatures of different areas of the cooling module includes detecting the temperatures of the upper part, the middle part, and the lower part of the cooling module.

[0055] Specifically, temperature sensors (marked as T1, T2 and T3) are arranged at the top, middle and bottom of the cooling module to monitor the air temperature in each area. The temperature sensor collects temperature data at the location in real time and transmits the data to the vehicle thermal management control system. By analyzing the temperature values ​​of T1, T2 and T3, the control system can evaluate the uniformity of the air intake of the cooling module, thereby providing a basis for the subsequent adjustment of the curvature of the air deflector to ensure that the airflow is optimally distributed according to the temperature requirements of each area, thereby improving the overall cooling effect of the cooling module.

[0056] In some embodiments, the air deflector includes a first variable curvature section located at a lower portion and a second variable curvature section located at an upper portion, and adjusting the curvature of the variable curvature section of the air deflector includes independently adjusting the curvatures of the first variable curvature section and the second variable curvature section.

[0057] Specifically, a first curvature variable section and a second curvature variable section are designed at the lower and upper parts of the air guide cover respectively, and the curvatures of the two curvature variable sections can be adjusted independently to optimize the airflow distribution. When the control system detects that the temperature of the upper or lower area of ​​the cooling module is uneven, the shapes of the first and second curvature variable sections can be adjusted according to actual needs.

[0058] When the upper airflow is insufficient, the curvature of the first curvature variable section is reduced to make the airflow closer to the upper guide, thereby guiding more airflow into the upper area; when the upper airflow is excessive, the first curvature is increased to reduce the upper airflow. This independent adjustment method allows the air guide cover to flexibly respond to different temperature requirements in each area, improving the dynamic adaptability and efficiency of the cooling system.

[0059] In some embodiments, the independent adjustment of the curvatures of the first variable curvature section and the second variable curvature section includes: when it is detected that the temperature of the upper portion of the cooling module is higher than the temperature of the middle and lower portions, reducing the curvature of the first variable curvature section, and at the same time controlling the second variable curvature section to bulge toward the outside of the air guide cover to increase the upper flow area, thereby increasing the air intake volume.

[0060] Specifically, refer to Figure 4 , when it is detected that the temperature of the upper part of the cooling module is higher than that of the middle and lower parts, the implementation method of the independent adjustment includes: reducing the curvature of the first variable curvature section (ab section) so that the lower airflow flows along the surface of the air guide cover, and more airflow is guided to the upper area through the Coanda effect, thereby increasing the upper cooling; at the same time, the second variable curvature section (cd section) is controlled to protrude toward the outside of the air guide cover to increase the upper flow area, thereby increasing the air intake. This operation can be automatically completed by the control system. After receiving the temperature sensor data, the control system judges and dynamically adjusts the first and second curvature sections according to the temperature difference to ensure that the airflow acts more concentratedly on the upper area with higher temperature. Specifically, the air guide cover curvature adjustment mechanism can be driven by a motor or an actuator to accurately control the curvature change amplitude so that the temperature of each area of ​​the cooling module tends to be uniform.

[0061] In some embodiments, independently adjusting the curvatures of the first and second variable curvature sections further includes: when it is detected that the temperature of the lower portion of the cooling module is higher than the temperature of the middle and upper portions, increasing the curvature of the first variable curvature section.

[0062] Specifically, refer to Figure 5 When it is detected that the temperature of the lower part of the cooling module is higher than that of the middle and upper parts, the independent adjustment includes: increasing the curvature of the first variable curvature segment (ab segment) to deflect the flow direction of the lower airflow, reduce the airflow adhering to the lower air guide area, and guide more airflow to flow under the cooling module. This adjustment method obtains real-time temperature data through the thermal management control system, and intelligently adjusts the curvature change range of the air guide according to the lower temperature requirements to ensure that the airflow is fully directed to the lower area with higher temperature.

[0063] In some embodiments, independently adjusting the curvatures of the first variable curvature segment and the second variable curvature segment further comprises: When it is detected that the temperature in the middle of the cooling module is higher than the temperature in the upper and lower parts, the curvature of the first variable curvature section is reduced, and at the same time, the second variable curvature section is controlled to be recessed toward the inner side of the air guide cover.

[0064] Specifically, refer to Figure 6 , when it is detected that the temperature in the middle of the cooling module is higher than the temperature in the upper and lower parts, the implementation method of the independent adjustment includes: reducing the curvature of the first variable curvature segment (ab segment) so that the lower airflow flows along the surface of the air guide cover, and more airflow is guided to the upper area through the Coanda effect, thereby increasing the upper cooling; at the same time, the second variable curvature segment (cd segment) is controlled to be recessed toward the inner side of the air guide cover, so that the intake air is separated from the surface of the air guide cover and blown to the middle of the cooling module. This operation can be automatically completed by the control system. After receiving the temperature sensor data, the control system judges and dynamically adjusts the first and second curvature segments according to the temperature difference to ensure that the airflow acts more concentratedly on the middle area with higher temperature. Specifically, the air guide cover curvature adjustment mechanism can be driven by a motor or an actuator to accurately control the curvature change amplitude so that the temperature of each area of ​​the cooling module tends to be uniform.

[0065] In some embodiments, the deflector control method further includes adjusting the curvature of the variable curvature section of the deflector according to the wind speed.

[0066] Specifically, when the wind speed changes during the driving of the vehicle, the wind speed data can be monitored in real time by the wind speed sensor, and the curvature variable section of the air deflector can be dynamically adjusted to optimize the airflow distribution. Under high wind speed conditions, the curvature of the lower first curvature variable section can be appropriately increased so that the airflow separates from the surface of the air deflector and flows to the lower area of ​​the cooling module, thereby reducing the excessive airflow in the upper area caused by excessive wind speed and avoiding uneven cooling. Under low wind speed conditions, the curvature of the lower first curvature variable section can be reduced to allow more airflow to enter the upper area and optimize the cooling effect. This method is controlled by the vehicle thermal management system, combined with the dual feedback of wind speed and temperature data, and the curvature is dynamically adjusted through the actuator to meet the cooling needs under different wind speeds.

[0067] In some embodiments, the air duct control method further includes adjusting the curvature of the variable curvature section of the air duct according to the working state of the cooling module.

[0068] Exemplarily, when the cooling module is in a high-load working state (such as when the vehicle is driving in a high-temperature environment or the battery temperature is relatively high), the curvature of the lower first curvature variable section can be increased according to the feedback information of the temperature sensor, so that more airflows are concentrated in the lower region, accelerating the heat dissipation of the high-temperature region. In the low-load state of the cooling module (such as when the vehicle is running at a low speed or in a low-temperature environment), the curvature of the first curvature variable section can be reduced, so that the airflow deflects upward on the surface of the airflow deflector, reducing the air volume in the lower part of the cooling module, thereby effectively avoiding over-cooling and saving energy consumption. This method realizes the intelligent adjustment of the curvature section of the deflector through the real-time monitoring data of the temperature and load state of the cooling module, combined with the automatic control of the thermal management system and the curvature adjustment actuator of the deflector, to meet the heat dissipation requirements of different working states of the cooling module.

[0069] Since the deflector of the cooling module can automatically adjust the curvature according to different vehicle speeds, wind speeds and temperature changes, the cooling system can maintain a stable heat dissipation performance under various working conditions. This method is particularly suitable for the requirements of electric vehicles under different environmental temperatures and operating states, which can effectively extend the service life of the cooling module and related components, and reduce the aging or damage of components caused by uneven heat dissipation.

[0070] Exemplarily, referring to Figure 7 , a specific embodiment of a deflector control method of the present invention has the following steps.

[0071] First, use a temperature sensor to collect the front-end intake air temperature. Temperature sensors T1, T2, and T3 are respectively arranged on the upper, middle, and lower parts of the cooling module to monitor the air temperature in each region. The collected data is transmitted to the vehicle's thermal management control system.

[0072] Next, use the vehicle's thermal management control system to process the temperature data sent by the temperature sensor and adjust the curvature section of the deflector through a series of judgments.

[0073] First, judge whether the upper temperature T1 is greater than the lower temperature T3.

[0074] If T1 > T3, it indicates that the upper part of the cooling module has a higher temperature at this time. Control the a-b section of the deflector to reduce the curvature, so that the airflow adheres to the surface of the deflector and flows upward, thereby increasing the cooling effect in the upper region.

[0075] If T1 < T3, it indicates that the upper part of the cooling module has a lower temperature at this time. Control the a-b section of the deflector to increase the curvature, guiding the airflow to flow more to the middle and lower regions to avoid over-cooling.

[0076] Next, judge whether T1 is equal to T3. If they are equal, further check the relationship between T1 and T2.

[0077] If T1>T2, it means that the upper temperature is still relatively high. Control the c-d section of the fairing to bulge outwards to increase the air flow in the lower part to balance the temperatures in each area.

[0078] If T1<T2, it means that the upper temperature is relatively low. Control the c-d section of the fairing to concave inwards to reduce the air flow in the upper part, thereby concentrating the air flow in the middle area.

[0079] Finally, perform an equilibrium state judgment. If after the above adjustments, the temperatures T1, T2, and T3 are equal, it means that the air flow uniformity of the cooling module reaches the optimal state, and the process ends.

[0080] Through the above embodiments, the curvature of the fairing is automatically adjusted according to the real-time temperature changes in different areas of the cooling module, and the air flow distribution is dynamically optimized, thereby ensuring the temperature uniformity and heat dissipation efficiency of the cooling module under different working conditions. Through the intelligent distribution of the air flow, it is ensured that each area of the cooling module is fully cooled without increasing additional energy consumption. Compared with the traditional fixed fairing, this method can strengthen the air flow supply in the high-temperature area directionally, while reducing the unnecessary air flow in the low-temperature area, avoiding unnecessary energy loss. This efficient air flow management method not only improves the heat dissipation performance of the cooling system, but also reduces the energy consumption of the electric vehicle, which helps to increase the cruising range.
