Technical Field

[0001] This application relates to the field of heat exchange module technology, and more specifically, to a heat exchange module and a vehicle. Background Technology

[0002] In existing technologies, traditional modular designs typically involve independently developing each heat exchanger (such as condenser, medium-temperature radiator, and high-temperature radiator) and cooling fan, which are then matched during assembly. This non-integrated development approach leads to alignment challenges between heat exchangers. Because each heat exchanger is designed independently, their cores often cannot be precisely aligned along the length of the heat exchanger. This misalignment not only reduces the effective heat dissipation area but also leads to a decrease in heat exchange efficiency, especially under tight space constraints.

[0003] There is currently no effective solution to the aforementioned technical problems. Summary of the Invention

This directly solves the problem of insufficient effective heat exchange area caused by differences in component dimensions in the prior art.

[0013] Furthermore, the radiator assembly is snapped into the condenser, and / or the radiator assembly is snapped into the cooling fan.

[0014] The optional embodiments described above achieve the following technical effects: by using a snap-fit ​​assembly method to replace some bolt installations, not only are material costs reduced, but the assembly process is also simplified, production time is shortened, and production efficiency is improved.

The connection between the medium-temperature radiator main board and the medium-temperature radiator core, as well as the welding between the medium-temperature radiator water chamber and the medium-temperature radiator main board, not only form a stable structure but also create a closed cavity. This facilitates the effective circulation of liquid coolant within the water chamber, while reducing potential leakage points and enhancing the system's sealing and reliability. The medium-temperature radiator eliminates the need for a sealing ring, reducing the radiator's width dimension and meeting the compactness requirements of the heat exchange module.

[0057] Currently, the design of automotive front-end heat exchange module assemblies faces a series of technical challenges. In traditional modular design, individual heat exchangers (such as condensers, medium-temperature radiators, and high-temperature radiators) and cooling fans are typically developed independently and then matched during the assembly phase. This non-integrated development approach leads to the following main problems:

[0058] 1) Alignment challenges between heat exchangers: Due to the independent design of each heat exchanger, their cores often cannot be precisely aligned in the Y-axis (i.e., the length direction of the heat exchanger). This misalignment not only reduces the effective heat dissipation area but also leads to a decrease in heat exchange efficiency, especially under tight space constraints. For example, medium-temperature radiators often use plastic water chambers. To ensure sealing, a sealing ring structure is required, which additionally increases the size of the water chamber in the X-axis (i.e., the thickness direction of the heat exchanger), further limiting the effective alignment of medium-temperature radiators with condensers and high-temperature radiators.

[0059] 2) Assembly Complexity and Cost: In existing technologies, heat exchangers and cooling fans mostly rely on bolts for fixing. This assembly method not only increases manufacturing costs due to the high procurement cost of bolts and nuts, but also lengthens the production cycle, as tightening each screw requires additional time. This problem is further exacerbated, especially for large-sized radiators and fans, which require more fixing points.

[0060] 3) Lack of flexibility in module design: With the development of different vehicle power configurations and thermal management systems, the front-end heat exchange module assembly needs to adapt to diverse system configurations. However, in existing technologies, module development is usually carried out for specific configurations, resulting in low product platformization and the inability to achieve effective sharing between different vehicle models, increasing the cost and time consumption of multiple redevelopment.

[0061] 4) Limitations of Medium-Temperature Radiators: The design of medium-temperature radiators is often constrained by material selection and structural limitations. While medium-temperature radiators using plastic water chambers are relatively common, the need for additional sealing grooves and sealing rings increases the size of the water chamber in the X-direction, affecting the overall size and cooling efficiency of the radiator. On the other hand, while using manifold-type medium-temperature radiators solves the size problem, it introduces increased water resistance, reduces the water flow rate, and affects cooling performance.

[0062] 5) Limited Cooling Fan Performance: In traditional designs, the performance of cooling fans is often limited by their structural design, particularly the shape of the fan shroud and the blade recess. Conventional fan shrouds are planar structures, with blade recesses typically only 3-4mm. To achieve greater airflow, the usual approach is to increase fan power, but this leads to increased cost and noise. In hybrid vehicles, the added cooling requirements for electric components place even stricter demands on the cooling fan. It requires not only greater airflow but also good performance under high back pressure, requirements that existing fan designs struggle to meet.

[0063] In summary, existing front-end heat exchange module assemblies have significant limitations in terms of design, cost control, and performance optimization. An innovative design solution is urgently needed to overcome these challenges and achieve a more efficient, lower-cost, and more flexible thermal management system.

[0064] Combination Figures 1 to 9 As shown, a heat exchange module is provided according to a specific embodiment of this application.

[0065] The heat exchange module includes a condenser 10, a radiator assembly 20, and a cooling fan 30. The radiator assembly 20 is connected to the condenser 10. At least a portion of the radiator core is coplanar with the end face formed by the first end along the length direction of the radiator core and the end face formed by the first end along the length direction of the condenser 10 core. At least a portion of the radiator core is extended toward the end face formed by the second end along the length direction of the condenser 10 core. The cooling fan 30 is connected to the radiator assembly 20, and the radiator assembly 20 is located between the condenser 10 and the cooling fan 30.

[0066] Compared to the closest prior art, the following design achieves the following effect: By having at least a portion of the heat sink core's first end face along its length coplanar with the first end face of the condenser 10's core along its length, and at least a portion of the heat sink core's second end extending towards the second end face of the condenser 10's core along its length, the heat sink core in the heat sink assembly 20 and the condenser 10's core ends are flush along the module's length. This effectively increases the effective heat exchange area between the heat sink core and the condenser 10's core, thereby improving heat exchange efficiency. This design overcomes the problems of reduced effective airflow and decreased heat exchange performance caused by inconsistent component sizes in traditional modules.

[0067] The cooling fan 30 is directly connected to the radiator assembly 20 and positioned after the condenser 10, forming a continuous and efficient airflow path from the cooling fan to the condenser. This layout reduces airflow resistance, ensuring that the airflow from the cooling fan can effectively act on the heat exchanger, thereby improving cooling efficiency.

[0068] Combination Figure 1 and Figure 2 As shown in the figure, in this embodiment, the Y direction represents the length direction of the radiator assembly 20, and the radiator core is flush with the core of the condenser 10 (e.g., Figure 2 The efficient layout of the heat exchange module (as shown) and the cooling fan works together to significantly improve the heat exchange efficiency of the heat exchange module. At the same time, the overall sealing strategy reduces the air leakage inside the module, ensuring full utilization of the air volume and further optimizing the performance of the thermal management system.

[0069] Furthermore, the radiator assembly 20 includes: a medium-temperature radiator 21, which is connected to the condenser 10; the end face formed by the first end of the core of the medium-temperature radiator 21 along the length direction and the end face formed by the first end of the core of the condenser 10 along the length direction are coplanarly disposed, and the second end of the core of the medium-temperature radiator 21 along the length direction extends toward the end face formed by the second end of the core of the condenser 10 along the length direction.

[0070] The above-mentioned optional embodiments of this application achieve the following technical effects: by increasing the effective heat exchange area between the core of the medium-temperature radiator 21 and the core of the condenser 10, the heat exchange efficiency and stability of the heat exchange module are significantly improved, and the air leakage problem is reduced by overall sealing, thus ensuring the effectiveness of the wind speed field.

[0071] Furthermore, the radiator assembly 20 includes: a high-temperature radiator 22, which is connected to a medium-temperature radiator 21 and a cooling fan 30. The medium-temperature radiator 21 is disposed between the condenser 10 and the high-temperature radiator 22. The end face formed by the first end of the core of the high-temperature radiator 22 along the length direction and the end face formed by the first end of the core of the condenser 10 along the length direction are coplanar. The second end of the core of the high-temperature radiator 22 along the length direction extends toward the end face formed by the second end of the core of the condenser 10 along the length direction.

[0072] The above-mentioned optional embodiments of this application achieve the following technical effects: by increasing the effective heat exchange area between the core of the high-temperature radiator 22 and the core of the condenser 10, the heat exchange efficiency and stability of the heat exchange module are significantly improved, and the air leakage problem is reduced by overall sealing, thus ensuring the effectiveness of the wind speed field.

[0073] Furthermore, the radiator assembly 20 includes a medium-temperature radiator 21 and a high-temperature radiator 22. The medium-temperature radiator 21 is connected to the condenser 10; the high-temperature radiator 22 is connected to the medium-temperature radiator 21 and is connected to the cooling fan 30. The medium-temperature radiator 21 is disposed between the condenser 10 and the high-temperature radiator 22. The end face formed by the first end of the core of the medium-temperature radiator 21 along the length direction, the end face formed by the first end of the core of the high-temperature radiator 22 along the length direction, and the end face formed by the first end of the core of the condenser 10 along the length direction are coplanar. The second end of the core of the medium-temperature radiator 21 and the second end of the core of the high-temperature radiator 22 along the length direction both extend toward the end face formed by the second end of the core of the condenser 10 along the length direction.

[0074] The above-mentioned optional embodiments of this application achieve the following technical effects: by increasing the effective heat exchange area between the core of the medium-temperature radiator 21, the core of the high-temperature radiator 22 and the core of the condenser 10 and by applying integral sealing cotton, the heat exchange efficiency and stability of the heat exchange module are significantly improved, the air leakage problem is reduced, and the effectiveness of the wind speed field is guaranteed.

[0075] Furthermore, the maximum height of the medium-temperature radiator 21, the maximum height of the high-temperature radiator 22, and the maximum height of the cooling fan 30 are set to be equal.

[0076] The above-mentioned optional embodiments of this application achieve the following technical effects: By setting the maximum height of the medium-temperature radiator 21, the maximum height of the high-temperature radiator 22, and the maximum height of the cooling fan 30 to be equal, a flush top design is achieved. The medium-temperature radiator 21, the high-temperature radiator 22, and the cooling fan 30 form a seamless interface in the top area. This design effectively optimizes airflow distribution, reduces airflow turbulence and resistance in the top area, thereby ensuring that the airflow generated by the cooling fan 30 can cover the entire radiator assembly more evenly and efficiently, improving heat exchange efficiency. At the same time, the flush top design also promotes tight sealing between modules, reduces the risk of air leakage, and further enhances the cooling effect. In terms of assembly process, this design simplifies the connection steps between the cooling fan and the radiator assembly, reduces reliance on additional components, and lowers assembly costs and difficulty. Furthermore, the implementation of the flush top design significantly enhances the heat exchange performance of the heat exchange module, improves the structural stability and long-term operational reliability of the module, and provides strong technical support for improving the efficiency and cost control of automotive thermal management systems by optimizing airflow management, simplifying the assembly process, and improving cost-effectiveness.

[0077] Furthermore, the radiator assembly 20 is snapped into the condenser 10, and the radiator assembly 20 is snapped into the cooling fan 30.

[0078] The optional embodiments described above achieve the following technical effects: by using a snap-fit ​​assembly method to replace some bolt installations, not only are material costs reduced, but the assembly process is also simplified, production time is shortened, and production efficiency is improved. Reducing the number of bolts helps to lower the total cost of the module while ensuring structural stability.

[0079] Furthermore, the heat exchange module also includes a first seal 41 and a second seal 42. The top of at least one of the medium-temperature radiator 21, the high-temperature radiator 22, and the cooling fan 30 of the radiator assembly 20 is connected to the first seal 41; the bottom of at least one of the condenser 10, the medium-temperature radiator 21, the high-temperature radiator 22, and the cooling fan 30 is connected to the second seal 42.

[0080] The above-described optional embodiments of this application achieve the following technical effects: By connecting the first seal 41 to the top of at least one of the medium-temperature radiator 21, the high-temperature radiator 22, and the cooling fan 30, and connecting the second seal 42 to the bottom, a comprehensive sealing system is formed. This not only enhances the airtightness of the airflow channel, preventing high-temperature gases from entering the engine compartment, but also ensures that the airflow generated by the cooling fan 30 is not unnecessarily lost when passing through the heat exchange module, thereby improving the cooling efficiency of each radiator. By adding the first seal 41 and the second seal 42, the sealing performance of the heat exchange module is significantly improved. This not only optimizes airflow management and cooling efficiency, but also enhances the module's durability and reduces maintenance costs, providing a more efficient, reliable, and quieter operating environment for the automotive thermal management system.

[0081] In one specific embodiment of this application, both the first sealing element 41 and the second sealing element 42 are sealing cotton.

[0082] Furthermore, the medium-temperature radiator 21 includes a medium-temperature radiator core 210, a medium-temperature radiator main board 211, and a medium-temperature radiator water chamber 212. The end face formed at the first end of the medium-temperature radiator core 210 along the length direction, the end face formed at the first end of the core of the high-temperature radiator 22 along the length direction, and the end face formed at the first end of the core of the condenser 10 along the length direction are coplanarly arranged. The end face formed at the second end of the medium-temperature radiator core 210 along the length direction, the end face formed at the second end of the core of the high-temperature radiator 22 along the length direction, and the end face formed at the second end of the core of the condenser 10 along the length direction are also coplanarly arranged. The medium-temperature radiator main board 211 is connected to the medium-temperature radiator core 210. The medium-temperature radiator water chamber 212 is connected to the medium-temperature radiator main board 211, and the medium-temperature radiator water chamber 212 and the medium-temperature radiator main board 211 enclose a cavity. The medium-temperature radiator main board 211 and the medium-temperature radiator water chamber 212 are welded together.

[0083] The above-mentioned optional embodiments of this application achieve the following technical effects: the end faces formed at the first end of the medium-temperature radiator core 210 along the length direction, the end faces formed at the first end of the high-temperature radiator core 22 along the length direction, and the end faces formed at the first end of the condenser core 10 along the length direction are coplanarly arranged, and the end faces formed at the second end of the medium-temperature radiator core 210 along the length direction, the end faces formed at the second end of the high-temperature radiator core 22 along the length direction, and the end faces formed at the second end of the condenser core 10 along the length direction are coplanarly arranged. This achieves that the medium-temperature radiator core 210, the high-temperature radiator core 22, and the condenser core 10 are flush with each other along the length direction of the medium-temperature radiator 21, increasing the effective heat exchange area of ​​the medium-temperature radiator core 210, the high-temperature radiator core 22, and the condenser core 10, ensuring the uniformity and efficiency of airflow through these components, reducing flow resistance, optimizing airflow distribution, and thus improving the overall heat exchange efficiency. The connection between the medium-temperature radiator mainboard 211 and the medium-temperature radiator core 210, as well as the welding between the medium-temperature radiator water chamber 212 and the medium-temperature radiator mainboard 211, not only form a robust structure but also create a closed cavity. This facilitates the effective circulation of liquid coolant within the water chamber, while reducing potential leakage points and enhancing the system's sealing and reliability. Furthermore, compared to traditional mechanical connections, the welding process provides higher connection strength and better sealing, ensuring the stability and durability of the medium-temperature radiator 21 under various operating conditions.

[0084] Combination Figure 3 and Figure 4 As shown, in this embodiment, the medium-temperature radiator water chamber 212 is made of aluminum, replacing the plastic water chamber in the prior art. The refined design of the medium-temperature radiator 21, through precise alignment and firm connection between the medium-temperature radiator core 210, the medium-temperature radiator main board 211 and the medium-temperature radiator water chamber 212, and the direct welding of the medium-temperature radiator main board 211 to the medium-temperature radiator water chamber 212, replaces the technical solution in the prior art that requires sealing cotton between the radiator main board and the plastic water chamber. This reduces the resistance during air flow and the risk of coolant leakage, significantly improves the heat exchange efficiency and structural stability of the heat exchange module, and thus optimizes the working performance of the overall thermal management system.

[0085] Furthermore, the maximum distance between the surface of the water chamber 212 of the medium-temperature radiator and the geometric center line in the width direction of the medium-temperature radiator main board 211 is L1, and the width of the medium-temperature radiator main board 211 is L2, wherein L1:L2 = 1:1.1 to 1:1.5.

[0086] The above-described optional embodiments of this application achieve the following technical effects: They ensure sufficient contact area between the medium-temperature radiator water chamber 212 and the medium-temperature radiator mainboard 211, while preventing the water chamber structure from becoming excessively large, thereby reducing unnecessary material usage and weight increase, achieving the goals of lightweighting and cost control. Furthermore, by maintaining this specific ratio, they ensure uniform distribution and effective circulation of coolant within the medium-temperature radiator water chamber 212, improving heat exchange efficiency. Simultaneously, the appropriate L1 to L2 ratio reduces dimensional constraints on the module assembly, providing more design space for other components such as the condenser 10 and the high-temperature radiator 22, enhancing the overall integration and flexibility of the module.

[0087] Combination Figure 4 and Figure 5 As shown in the figure, the Y direction is the length direction of the medium-temperature radiator core 210, and the X direction is the width direction of the medium-temperature radiator core 210. L1 is parallel to the Y direction, and L2 is parallel to the X direction. The medium-temperature radiator water chamber 212 increases the Y direction while reducing the X direction dimension, which not only optimizes the size of the medium-temperature radiator water chamber 212, but also overcomes the problem of increased water resistance and improves the space utilization rate.

[0088] Furthermore, the projection of the water chamber 212 of the medium-temperature radiator along the height direction of the medium-temperature radiator 21 is an arc.

[0089] The optional embodiments described above achieve the following technical effects: the arc projection design facilitates a smoother flow path of the coolant within the water chamber, reducing turbulence and vortices as the fluid enters and exits the water chamber, thereby lowering flow resistance. This allows the coolant to be distributed more quickly and evenly into the mid-temperature radiator core 210. The arc shape also expands the internal capacity of the water chamber to some extent, reducing flow resistance and increasing flow velocity, thus improving the radiator's heat conversion efficiency. Moreover, this design may also help reduce the weight of the water chamber itself. By using lightweight materials and optimizing the shape, a balance between structural strength and weight can be achieved, which is particularly important in modern automotive designs that pursue lightweighting and energy efficiency.

[0090] Combination Figure 4 and Figure 5 As shown, the projection of the medium-temperature radiator main board 211 and the medium-temperature radiator water chamber 212 along the height direction of the medium-temperature radiator 21 is similar to a "D" shape, which helps to increase the storage capacity of coolant. Especially under high load conditions, it can provide a more stable coolant supply, ensuring that the radiator can perform the best cooling effect under various operating conditions.

[0091] Furthermore, the medium-temperature radiator core 210 includes multiple core units, which are arranged sequentially along the height direction of the medium-temperature radiator core 210.

[0092] The above-mentioned optional embodiments of this application achieve the following technical effects: The longitudinal arrangement of multiple core units increases the surface area in contact with the airflow generated by the cooling fan 30, thereby improving heat exchange efficiency. Especially under high heat load conditions, each independent unit can more efficiently distribute heat, avoiding the problem of local overheating. Secondly, this modular design provides high flexibility, allowing the number of core units to be increased or decreased according to the specific needs of different vehicle models, adjusting the heat dissipation capacity without having to redesign the entire radiator structure, greatly reducing customization costs and enhancing the versatility and platform application capabilities of the medium-temperature radiator 21.

[0093] Combination Figures 6 to 7 As shown, in a specific embodiment of this application, the intermediate-temperature radiator core 210 includes an electric drive radiator core 2101 and an intercooler radiator core 2102, and the intermediate-temperature radiator water chamber 212 includes an electric drive radiator water chamber 2121 and an intercooler radiator water chamber 2122. The electric drive radiator core 2101 is connected to the electric drive radiator water chamber 2121, and the intercooler radiator core 2102 is connected to the intercooler radiator water chamber 2122. This configuration allows the radiator system to more accurately manage heat for different heat sources while maintaining overall compactness and efficiency. The electric drive radiator core 2101, connected to the electric drive radiator water chamber 2121, is specifically responsible for cooling the electric drive system. It can quickly respond to the high heat load of the electric drive system during startup and acceleration, effectively preventing overheating of the electric drive system, extending its service life, and ensuring stable vehicle power performance. The combination of the intercooler core 2102 and the intercooler water chamber 2122 focuses on cooling the engine intake air. Especially when the engine is running under high load, it can significantly reduce the temperature of the air entering the engine, improve combustion efficiency, reduce emissions, and improve the overall performance of the engine.

[0094] Specifically, by subdividing the medium-temperature radiator 21 into an electric drive radiator core 2101 and an intercooler radiator core 2102, and equipping each with a water chamber, the present invention not only achieves precise heat management of different heat sources, but also improves the response speed and efficiency of the entire thermal management system. At the same time, it reduces the dependence on a single large radiator, making the system more flexible in structure and easy to adjust according to different vehicle configurations and operating conditions.

[0095] Furthermore, the cooling fan 30 includes a cover 31, a motor 32, and an impeller 33. The cover 31 is connected to the radiator assembly 20 and is provided with an air passage 311. The base of the motor 32 is connected to the cover 31 and the motor 32 is disposed in the air passage 311. The impeller 33 is connected to the output shaft of the motor 32 and is disposed in the air passage 311. The surface of the cover 31 facing the high-temperature radiator 22 is recessed along the axis of the impeller 33 away from the high-temperature radiator 22.

[0096] The above-mentioned optional embodiments of this application achieve the following technical effects: The cover 31 is tightly connected to the radiator assembly 20, ensuring that the cooling fan is in the optimal air intake and exhaust position, directly facing the medium-temperature radiator 21 and the high-temperature radiator 22, thus optimizing the direct airflow transmission path. The connection design between the base of the motor 32 and the cover 31 places the motor within the air passage 311. This layout not only saves space but also allows the heat of the motor to be carried away by the cooling airflow, reducing the motor's operating temperature and extending its service life. The impeller 33 is directly connected to the output shaft of the motor 32 and is placed within the air passage 311, ensuring that the distance between the fan blades and the radiator is within the optimal range, thereby reducing airflow loss, improving airflow utilization, and enhancing the cooling effect. The recessed design on the surface of the cover 31 facing the high-temperature radiator 22 along the impeller axis is essentially a flow guide design. It guides the airflow to flow more concentratedly and smoothly towards the impeller 33, reduces the separation and backflow of airflow at the edge of the cover 31, effectively reduces the turbulence of airflow near the cover 31, improves the transmission efficiency of air volume and air pressure, and also helps to improve the NVH performance of the cooling fan 30 and reduce operating noise.

[0097] Furthermore, the cover 31 includes a cover body 310 and a reinforcing rib 312. The cover body 310 is provided with an air passage 311. The reinforcing rib 312 is connected to the cover body 310 and is located on one side of the air passage 311. The base of the motor 32 is connected to the reinforcing rib 312, and the motor 32 is located between the reinforcing rib 312 and the impeller 33.

[0098] The optional embodiments described above achieve the following technical effects: The air passage 311 provided on the housing body 310 provides an optimized flow path for airflow, ensuring unobstructed airflow through the heat exchange module components while reducing turbulence and pressure loss, which is crucial for improving cooling efficiency. Furthermore, the design of the air passage 311 guides airflow to more evenly cover the heat dissipation elements, preventing localized overheating and further enhancing system performance. The connection between the reinforcing rib 312 and the housing body 310 not only increases the rigidity of the housing, preventing deformation under high-speed operation or harsh conditions, but also provides a stable support point for the installation of the motor 32, ensuring the smooth and efficient operation of the motor 32. The motor 32 is positioned between the reinforcing rib 312 and the impeller 33. This arrangement allows the motor 32 to better drive the impeller 33, while the presence of the reinforcing rib 312 helps to disperse vibrations during motor operation, reducing operating noise and improving the overall NVH performance of the cooling fan 30.

[0099] Combination Figure 8As shown, in one specific embodiment of this application, the cover 31 integrates the cover body 310, the optimized air passage 311, and the added reinforcing ribs 312. This design significantly improves airflow efficiency, enhances structural stability, and improves the NVH performance of the cooling fan 30 by rationally arranging the motor 32, thereby reducing operating noise. This innovation not only improves the working efficiency of the cooling fan itself but also indirectly improves the thermal management capability of the entire heat exchange module.

[0100] Furthermore, the air passage 311 has an air inlet 3111, and the impeller 33 is positioned at a distance from the air inlet 3111.

[0101] The above-mentioned optional embodiments of this application achieve the following technical effects: Increasing the length of the air passage 311 and setting the impeller 33 at a distance from the air inlet 3111 (the distance can be set to 8mm-12mm) reduces the influence of tip clearance vortices caused by impeller deformation under high back pressure. Simultaneously, the downward design of the impeller 33 helps improve airflow distribution and reduces vortices caused by the increased tip clearance due to high-speed rotation and deformation of the impeller 33 under high back pressure. This allows the cooling airflow to pass more evenly through the air passage 311, covering the entire surface of the radiator and improving heat exchange efficiency. From the perspective of NVH (noise, vibration, and harshness) performance, the distance between the impeller 33 and the air inlet 3111 also reduces aerodynamic noise and vibration during operation, providing a quieter driving environment.

[0102] Combination Figure 9 As shown, in a specific embodiment of this application, by designing a reasonable spacing between the impeller 33 and the end of the air passage 311 away from the reinforcing rib 312, the cooling fan 30 of the present invention not only improves mechanical efficiency, but also optimizes airflow distribution and reduces aerodynamic noise and vibration.

This new heat exchange module not only significantly improves heat exchange efficiency and reduces operating costs, but also enhances the driving experience and reduces environmental impact by reducing weight and optimizing NVH performance.
