Description

Technical Field

[0001] This application belongs to the field of vehicle cooling technology, and more specifically, relates to a radiator assembly and a vehicle. Background Technology

[0002] During vehicle operation, due to the high resistance inside the engine compartment, the hot air after passing through the front module cannot flow away in time, which leads to increased pressure. Some of the hot air flows back through the gaps around the radiator to the front module, and then passes through the radiator with the cold air in front, thus reducing the heat dissipation efficiency. This phenomenon is called hot air recirculation.

[0003] To prevent hot air backflow, a backflow prevention device is usually installed around the radiator edge. The most common solution is to attach a sponge baffle to the radiator edge with strong adhesive, using its porous elastomer to fill the gaps and block the backflow path of hot air. However, the engine compartment is in a harsh environment of high temperature, vibration, and oil contamination for a long time. Under these conditions, the sponge material is prone to aging, embrittlement, and even pulverization, and its elasticity and filling capacity will rapidly decrease. At the same time, the adhesive used for bonding will have significantly reduced bonding strength at high temperatures, and may even fail completely after long-term thermal aging, causing the sponge baffle to fall off. This not only results in the loss of its protective function but may also pose a safety hazard to the high-speed rotating cooling fan.

[0004] Another technical approach involves placing a shroud between the radiator and the cooling fan as a transitional connecting component to guide airflow. However, to prevent the shroud from interfering with or colliding with the cooling fan blades during vehicle vibrations, a certain safety gap must be provided in the design. It is precisely this gap that can generate uncontrolled secondary flow or air leakage when the fan is operating, significantly disrupting the stability of the main airflow field, reducing the cooling fan's ventilation efficiency, and similarly hindering the radiator's full performance. Utility Model Content

[0005] The purpose of this application is to provide a radiator assembly and vehicle that aims to solve the problems of insufficient connection reliability and ventilation efficiency in existing hot air recirculation prevention solutions.

[0006] In a first aspect, embodiments of this application provide a radiator assembly, including a high-temperature radiator and a low-temperature radiator spaced apart along an air outlet path, wherein a heat dissipation space is formed between the high-temperature radiator and the low-temperature radiator, and further including a partition connected to the high-temperature radiator, the partition comprising: The main body is used to shield the heat dissipation space; A mounting portion, connected to the main body and angled relative to the main body, is detachably connected to the high-temperature radiator; and A sealing part is connected to the main body, the sealing part and the mounting part are located on opposite sides of the main body, and the sealing part is sealed and overlapped with the low temperature heat sink.

[0007] The beneficial effects of the hot air recirculation prevention device provided in this application are as follows: Compared with the prior art, the separator is installed on the high-temperature radiator in a detachable manner, and the sealing part is made of elastic material and overlaps with the low-temperature radiator. This not only eliminates the dependence on adhesives and avoids the risk of detachment due to adhesive aging and embrittlement, but is also particularly suitable for the high-temperature and high-vibration engine compartment environment. Moreover, by utilizing the continuous deformation generated by the elastic material under pressure, it automatically adapts to changes in structural gaps caused by manufacturing tolerances, thermal deformation, and vibration, ensuring good airtightness under different operating conditions and fundamentally suppressing hot air recirculation and secondary flow phenomena. This application effectively shields the heat dissipation space between the high-temperature radiator and the low-temperature radiator by the main body, blocking the hot air recirculation path, and reducing uncontrolled air leakage caused by gaps between components. This allows the cooling fan to form a more stable and concentrated flow field, significantly improving the ventilation efficiency and heat exchange performance of the overall heat dissipation system.

[0008] In conjunction with the first aspect, in one possible implementation, the high-temperature radiator includes a high-temperature heat sink and a mounting flange connected to the high-temperature heat sink. The mounting flange is bent outward, and the mounting portion has a mounting groove in which the mounting flange is inserted.

[0009] In the above technical solution, the mounting groove in the mounting section and the outwardly bent mounting flange on the high-temperature radiator form a plug-in fit, realizing the rapid positioning and mechanical fixation of the separator on the high-temperature radiator. This plug-in installation method not only avoids the risk of high-temperature aging and detachment caused by using adhesives, significantly improving connection reliability, but also eliminates the need for external connecting parts, simplifying the installation steps and improving installation efficiency.

[0010] In conjunction with the first aspect, in one possible implementation, the mounting flange is provided with a locking hole, and the separator further includes a locking part disposed in the mounting groove, the locking part being inserted into the locking hole.

[0011] In the above technical solution, the mounting flange and mounting groove are inserted and fitted in the inward and outward directions, and the locking part and locking hole are inserted and fitted in the air outlet path, thereby achieving multi-directional limiting and effectively resisting multi-directional displacement and loosening that may be caused by vibration during vehicle operation, ensuring the connection stability of the partition under long-term vibration conditions. At the same time, the locking structure is compact and concealed, without changing the layout of the radiator body, thus improving installation reliability while maintaining structural simplicity.

[0012] In conjunction with the first aspect, in one possible implementation, the separator further includes a fixing lip disposed within the mounting groove, the fixing lip abutting against the mounting flange.

[0013] In the above technical solution, the fixed lip undergoes elastic deformation during the insertion of the mounting flange, continuously applying a clamping force to the mounting flange. This not only effectively eliminates assembly gaps and prevents abnormal noises and loosening caused by vibration, but also significantly improves the tightness of the connection between the mounting groove and the mounting flange, ensuring that the partition maintains a reliable installation state under vehicle vibration and heat load conditions. This embodiment, by providing a fixed lip within the mounting groove, allows for a tight contact with the mounting flange after insertion, further enhancing the connection stability and sealing effect between the partition and the high-temperature radiator.

[0014] In conjunction with the first aspect, in one possible implementation, the mounting part has anti-slip texture, the high-temperature radiator has a fixing groove adapted to the mounting part, the mounting part is inserted into the fixing groove, and the anti-slip texture is used to increase the friction between the mounting part and the high-temperature radiator.

[0015] In the above technical solution, anti-slip texture is provided on the surface of the mounting part, which can effectively increase the friction between the contact surfaces when it is plugged into the high-temperature radiator. This not only significantly reduces the risk of relative sliding or loosening between the mounting part and the radiator due to continuous vibration during vehicle operation, but also further improves the tightness and stability of the plug-in connection. Thus, without the need to add additional locking elements, the anti-loosening performance of the partition is enhanced, ensuring the long-term effective operation of the anti-hot air backflow function.

[0016] In conjunction with the first aspect, in one possible implementation, the low-temperature radiator includes a low-temperature heat sink and an overlapping flange connected to the low-temperature heat sink, the overlapping flange being bent outwards, and the sealing portion sealingly overlapping the overlapping flange.

[0017] In the above technical solution, the overlapping flange serves as a sealing interface, preventing interference between the sealing part and the low-temperature heat sink. Furthermore, the smooth surface of the overlapping flange enhances sealing reliability. The supporting effect of the overlapping flange also makes it easier to position and align the sealing part during assembly, ensuring a uniform distribution of sealing pressure. This overlapping sealing structure effectively adapts to system vibration and thermal deformation, preventing hot air recirculation while avoiding stress concentration caused by rigid connections. Thus, while simplifying the structure, it significantly improves the sealing durability and operational reliability of the radiator assembly during long-term operation.

[0018] In conjunction with the first aspect, in one possible implementation, the sealing part includes a connecting piece and a baffle connected at an angle to the connecting piece. The connecting piece is connected to the main body and sealably overlaps the low-temperature radiator. The baffle is located on the side of the low-temperature radiator away from the high-temperature radiator and sealably abuts against the low-temperature radiator.

[0019] In the above technical solution, the connecting piece and the baffle are connected at an angle to each other. The connecting piece seals and overlaps with the surface of the low-temperature radiator, while the baffle is located on the side of the low-temperature radiator facing away from the high-temperature radiator and seals against it, thus forming a two-way closed sealing structure at the edge of the low-temperature radiator. This solution not only achieves a large-area stable overlap with the surface of the low-temperature radiator through the connecting piece, effectively blocking the infiltration of lateral airflow, but also provides a vertical seal on the air outlet path through the baffle, preventing reverse leakage caused by pressure fluctuations. The dual sealing mechanism works synergistically to significantly improve the integrity and reliability of the sealing interface, enabling the radiator assembly to effectively suppress hot air backflow and airflow interference under complex operating conditions, ensuring the efficient and stable operation of the radiator assembly.

[0020] In conjunction with the first aspect, in one possible implementation, the overlapping flange includes a support piece and an overlapping piece distributed at an angle, the support piece being connected to the low-temperature heat sink and extending outward, and the overlapping piece extending along the air outlet path and sealingly fitting against the sealing portion.

[0021] In the above technical solution, the overlapping flange is designed as a support plate and an overlapping plate distributed at an angle to each other. The support plate is connected to the low-temperature heat sink and extends outward to provide structural support, while the overlapping plate extends along the air outlet path and forms a sealed fit with the sealing part. This not only avoids the problem of interference caused by direct contact between the sealing part and the low-temperature heat sink, but also increases the contact area with the sealing part, improving the reliability of the seal. In addition, this structure effectively disperses the sealing pressure borne by the overlapping plate through the support plate, avoiding local stress concentration. At the same time, the overlapping plate extending along the air outlet path can form a smooth transition surface with the sealing part in the direction of airflow, which reduces flow resistance and achieves multi-dimensional sealing of the hot air return path.

[0022] In conjunction with the first aspect, in one possible implementation, the main body and the mounting portion are rigid components, and the sealing portion is a flexible component.

[0023] In the above technical solution, the main body and mounting section are designed as rigid components, ensuring sufficient strength and stability for the overall structure of the separator, enabling reliable fixation to the high-temperature radiator. Simultaneously, the sealing section employs a flexible component, utilizing its elastic deformation capability to effectively compensate for assembly tolerances between the high and low temperature radiators. Furthermore, it maintains a tight fit even when the system expands and contracts due to temperature changes, achieving a dynamically adaptive long-term sealing effect. This integrated rigid-flexible design ensures both the robustness and durability of the installation connection and provides the sealing interface with excellent adaptability, effectively suppressing the widening of the sealing gap caused by vibration, temperature fluctuations, and structural deformation. This ensures a consistently efficient and reliable hot air backflow protection function even in complex working environments.

[0024] Secondly, embodiments of this application also provide a vehicle including the radiator assembly described above.

[0025] The beneficial effects of the vehicle provided in this application are as follows: Compared with the prior art, the radiator assembly described above uses a detachable partition installed on the high-temperature radiator, and the sealing part uses an elastic material to seal and overlap with the low-temperature radiator. This not only eliminates the dependence on adhesives and avoids the risk of detachment due to adhesive aging and embrittlement, but is also particularly suitable for the high-temperature, high-vibration engine compartment environment. Furthermore, by utilizing the continuous deformation generated by the elastic material under pressure, it automatically adapts to changes in structural gaps caused by manufacturing tolerances, thermal deformation, and vibration, ensuring good airtightness under different operating conditions and fundamentally suppressing hot air recirculation and secondary flow phenomena. This application effectively shields the heat dissipation space between the high-temperature and low-temperature radiators by the main body, blocking the hot air recirculation path and reducing uncontrolled air leakage caused by gaps between components. This allows the cooling fan to form a more stable and concentrated flow field, significantly improving the ventilation efficiency and heat exchange performance of the overall cooling system.

[0035] It should be noted that "air outlet path" refers to the airflow path in the radiator assembly, that is, the path parallel to the air outlet path of the cooling fan.

[0036] Please refer to the following: Figures 1 to 6 The radiator assembly and vehicle provided in this application will now be described. The radiator assembly includes a high-temperature radiator 1 and a low-temperature radiator 2 spaced apart along the air outlet path, forming a heat dissipation space between the high-temperature radiator 1 and the low-temperature radiator 2. It also includes a partition 3 connected to the high-temperature radiator 1. The partition 3 includes a main body 301, a mounting part 302 and a sealing part 303. The main body 301 is used to shield the heat dissipation space. The mounting part 302 is connected to the main body 301 and is distributed at an angle to the main body 301. The mounting part 302 is detachably connected to the high-temperature radiator 1. The sealing part 303 is connected to the main body 301. The sealing part 303 and the mounting part 302 are located on opposite sides of the main body 301, and the sealing part 303 seals and overlaps with the low-temperature radiator 2.

[0037] Compared with the prior art, the radiator assembly provided in this application features a detachable partition 3 installed on the high-temperature radiator 1, and a sealing part 303 made of elastic material that seals against the low-temperature radiator 2. This not only eliminates the reliance on adhesives and avoids the risk of detachment due to adhesive aging and embrittlement, making it particularly suitable for the high-temperature, high-vibration engine compartment environment, but also utilizes the continuous deformation of the elastic material under pressure to automatically adapt to changes in structural gaps caused by manufacturing tolerances, thermal deformation, and vibration. This ensures good airtightness under different operating conditions and fundamentally suppresses hot air recirculation and secondary flow phenomena. The main body 301 effectively shields the heat dissipation space between the high-temperature radiator 1 and the low-temperature radiator 2, blocking the hot air recirculation path and reducing uncontrolled air leakage caused by gaps between components. This allows the cooling fan to form a more stable and concentrated flow field, significantly improving the ventilation efficiency and heat exchange performance of the overall cooling system.

[0038] Optionally, the mounting part 302 can be snapped, screwed, clamped, plugged in, or riveted to the high-temperature radiator 1.

[0039] Optionally, two separators 3 are provided, and the two separators 3 are arranged on opposite sides of the high-temperature radiator 1 in the vertical direction.

[0040] Optionally, the sealing part 303 can be a rubber or silicone component. The main body 301 and the mounting part 302 can be plastic or metal components.

[0041] Please see Figures 2 to 3 In some embodiments, the high-temperature radiator 1 includes a high-temperature heat sink 101 and a mounting flange 102 connected to the high-temperature heat sink 101. The mounting flange 102 is bent outward, and the mounting part 302 has a mounting groove 3021, in which the mounting flange 102 is inserted.

[0042] In this embodiment, the mounting part 302 is configured with a mounting groove 3021, which interlocks with the mounting flange 102 bent outward on the high-temperature radiator 1, achieving rapid positioning and mechanical fixation of the separator 3 on the high-temperature radiator 1. This interlocking installation method not only avoids the risks of high-temperature aging and detachment caused by adhesives, significantly improving connection reliability, but also eliminates the need for external connecting parts, simplifying the installation process and improving installation efficiency. Furthermore, the interlocking installation method can also form a limiting structure in the direction perpendicular to the interlocking path, enhancing the stability of the installation.

[0043] Optionally, the mounting flange 102 can be interference-fitted with the mounting slot 3021, or it can be snap-fitted. Optionally, the mounting flange 102 is inserted into the mounting groove 3021 in the inward and outward directions.

[0044] Please see Figure 4 In some embodiments, the mounting flange 102 has a locking hole, and the separator 3 also includes a locking part 3023 disposed in the mounting groove 3021, the locking part 3023 being inserted into the locking hole.

[0045] This embodiment achieves a more stable and reliable mechanical connection between the partition 3 and the high-temperature radiator 1 by providing a locking hole on the mounting flange 102 and a locking part 3023 that can be inserted into the locking hole along the air outlet path in the mounting groove 3021 of the partition 3. This dual fixing method of insertion and locking, where the mounting flange 102 and the mounting groove 3021 are inserted and engaged in the inward and outward directions, and the locking part 3023 and the locking hole are inserted and engaged in the air outlet path, achieves multi-directional limiting, effectively resisting multi-directional displacement and loosening that may occur due to vibration during vehicle operation, and ensuring the connection stability of the partition 3 under long-term vibration conditions. At the same time, this locking structure is compact and concealed, requiring no changes to the layout of the radiator body 301, improving installation reliability while maintaining structural simplicity, and providing a guarantee for the long-term efficient operation of the radiator assembly in harsh environments.

[0046] Optionally, the locking part 3023 is an elastic member, and locking is achieved through an interference fit after the locking part 3023 is inserted into the locking hole. For example, both the locking part 3023 and the mounting part 302 are rubber members, and the rubber members are inserted into the locking hole to achieve locking through elastic deformation force.

[0047] Optionally, the locking part 3023 is a snap-fit, which is inserted into the locking hole to achieve a snap-fit ​​engagement.

[0048] Please see Figures 2 to 3 In some embodiments, the separator 3 further includes a fixing lip 3022 disposed in the mounting groove 3021, the fixing lip 3022 abutting against the mounting flange 102.

[0049] The fixed lip 3022 undergoes elastic deformation during the insertion of the mounting flange 102, continuously applying a clamping force to the mounting flange 102. This not only effectively eliminates assembly gaps and prevents abnormal noises and loosening caused by vibration, but also significantly improves the tightness of the connection between the mounting groove 3021 and the mounting flange 102, ensuring that the separator 3 maintains a reliable installation state under vehicle vibration and heat load conditions. In this embodiment, by providing a fixed lip 3022 within the mounting groove 3021, it can form a tight abutment with the mounting flange 102 after insertion, further enhancing the connection stability and sealing effect between the separator 3 and the high-temperature radiator 1.

[0050] Optionally, two sets of fixed lips 3022 are provided along the air outlet path, and the two sets are arranged in a mirror-symmetrical manner. The mounting flange 102 is inserted between the two sets of fixed lips 3022. By symmetrically arranging the two sets of fixed lips 3022 along the air outlet path, the mounting flange 102 is subjected to symmetrical elastic clamping forces on both sides after insertion, forming a bidirectional balanced constraint effect. This symmetrical layout not only significantly increases the effective contact area but also ensures that the mounting flange 102 remains in a state of mechanical equilibrium when subjected to vibration and impact from different directions, effectively suppressing swaying and displacement tendencies. Of course, in feasible embodiments, the bending angle of the mounting flange 102 can be adjusted. Two sets of fixed lips 3022 are radially symmetrical about the mounting flange 102 as a plane of symmetry. When the mounting flange 102 is not parallel to the air outlet path, the fixed lips 3022 may form an angle with the air outlet path.

[0051] Optionally, multiple fixed lips 3022 are provided along the inner and outer directions to increase the contact area with the mounting flange 102 and improve the reliability of the connection.

[0052] Optionally, the fixing lip 3022 is a resilient member, such as a rubber or silicone member.

[0053] Optionally, the fixing lip 3022 is set at an angle to the mounting portion 302 and is inclined toward the insertion direction of the mounting flange 102. The angle between the fixing lip 3022 and the mounting portion 302 is 45-55°, and the free end is inclined toward the insertion direction of the mounting flange 102.

[0054] Please see Figure 1 In some embodiments, the mounting part 302 has anti-slip texture, and the high-temperature radiator 1 has a fixing groove adapted to the mounting part 302. The mounting part 302 is inserted into the fixing groove, and the anti-slip texture is used to increase the friction between the mounting part 302 and the high-temperature radiator 1.

[0055] This embodiment provides anti-slip textures on the surface of the mounting part 302, which effectively increases the friction between the contact surfaces when it is plugged into the high-temperature radiator 1. This not only significantly reduces the risk of relative sliding or loosening between the mounting part 302 and the radiator due to continuous vibration during vehicle operation, but also further improves the tightness and stability of the plug-in connection. Thus, without the need to add additional locking elements, the anti-loosening performance of the separator 3 is enhanced, ensuring the long-term effective operation of the anti-hot air backflow function.

[0056] Optionally, the anti-slip texture can be hemispherical or strip-shaped.

[0057] Please see Figures 2 to 3 In some embodiments, the low-temperature radiator 2 includes a low-temperature heat sink 201 and an overlapping flange 202 connected to the low-temperature heat sink 201. The overlapping flange 202 is bent outward, and the sealing part 303 is sealed and overlapped with the overlapping flange 202.

[0058] This embodiment utilizes the overlapping flange 202 as a sealing interface to avoid interference between the sealing part 303 and the low-temperature heat sink 201. The smooth surface of the overlapping flange 202 improves sealing reliability. Furthermore, the supporting effect of the overlapping flange 202 makes it easier to position and align the sealing part 303 during assembly, ensuring a uniform distribution of sealing pressure. This overlapping sealing structure effectively adapts to system vibration and thermal deformation, preventing hot air backflow while avoiding stress concentration caused by rigid connections. Thus, while simplifying the structure, it significantly improves the sealing durability and operational reliability of the radiator assembly during long-term operation.

[0059] Please see Figure 5 In some embodiments, the sealing part 303 includes a connecting piece 3031 and a baffle 3032 connected to the connecting piece 3031 at an angle. The connecting piece 3031 is connected to the main body 301 and seals against the low-temperature radiator 2. The baffle 3032 is located on the side of the low-temperature radiator 2 away from the high-temperature radiator 1 and seals against the low-temperature radiator 2.

[0060] This application designs the sealing part 303 as a connecting piece 3031 and a baffle 3032 connected at an angle to each other. The connecting piece 3031 seals and overlaps with the surface of the low-temperature radiator 2, while the baffle 3032 is located on the side of the low-temperature radiator 2 facing away from the high-temperature radiator 1 and seals against it, thus forming a bidirectional closed sealing structure at the edge of the low-temperature radiator 2. This solution not only achieves a large-area stable overlap with the surface of the low-temperature radiator 2 through the connecting piece 3031, effectively blocking the infiltration of lateral airflow, but also seals the air outlet path through the baffle 3032, preventing reverse leakage caused by pressure fluctuations. The dual sealing mechanism works synergistically to significantly improve the integrity and reliability of the sealing interface, enabling the radiator assembly to effectively suppress hot air backflow and airflow interference under complex operating conditions, ensuring the efficient and stable operation of the radiator assembly.

[0061] Optionally, the connecting piece 3031 and the baffle 3032 are integral components, and both are elastic components with good elastic deformation capacity.

[0062] Please see Figure 6 In some embodiments, the overlapping flange 202 includes a support piece 2021 and an overlapping piece 2022 distributed at an angle. The support piece 2021 is connected to the low-temperature heat sink 201 and extends outward. The overlapping piece 2022 extends along the air outlet path and is sealed and fitted to the sealing part 303.

[0063] In this embodiment, the overlapping flange 202 is designed as a support piece 2021 and an overlapping piece 2022 distributed at an angle to each other. The support piece 2021 is connected to the low-temperature heat sink 201 and extends outward to provide structural support, while the overlapping piece 2022 extends along the air outlet path and forms a sealed fit with the sealing part 303. This not only avoids the problem of interference caused by the sealing part 303 directly contacting the low-temperature heat sink 201, but also increases the contact area with the sealing part 303, improving the reliability of the seal. In addition, this structure effectively disperses the sealing pressure borne by the overlapping piece 2022 through the support piece 2021, avoiding local stress concentration. At the same time, the overlapping piece 2022 extending along the air outlet path can form a smooth transition surface with the sealing part 303 in the direction of airflow, which reduces flow resistance and achieves multi-dimensional sealing of the hot air return path.

[0064] Optionally, the support piece 2021 and the overlapping piece 2022 are integral components, and both are rigid structures.

[0065] Please see Figures 2 to 3 In some embodiments, the main body 301 and the mounting part 302 are rigid components, and the sealing part 303 is a flexible component.

[0066] In this embodiment, by setting the main body 301 and the mounting part 302 as rigid components, the overall structure of the separator 3 has sufficient strength and stability, enabling reliable fixation to the high-temperature radiator. Simultaneously, the sealing part 303 employs a flexible component, utilizing its elastic deformation capability to effectively compensate for the assembly tolerances between the high- and low-temperature radiators 2, and to maintain a tight fit even when the system expands and contracts due to temperature changes, achieving a dynamically adaptive long-term sealing effect. This integrated rigid-flexible design ensures both the robustness and durability of the installation connection, while also providing the sealing interface with excellent adaptability. It effectively suppresses the widening of the sealing gap caused by vibration, temperature fluctuations, and structural deformation, thereby maintaining a highly efficient and reliable hot air backflow protection function in complex working environments.

[0067] Optionally, the main body 301 and mounting part 302 are made of plastic components, such as PP (polypropylene) components, while the sealing part 303 is made of TPV (thermoplastic vulcanizate) components. TPV is a combination of plastic and rubber properties, generally referring to a blend system of PP and EPDM. Thermoplastic vulcanizate is currently the most advanced polyolefin thermoplastic elastomer prepared using dynamic full vulcanization technology. The main body 301 and mounting part 302 are made of high-hardness PP material with a temperature resistance of over 120℃, which ensures rapid assembly while forming a high-strength mechanical interlock, completely solving the problem of easy aging and detachment of traditional rubber sealing strips; while the sealing part 303 is made of TPV material with an elastic modulus of 10-50 MPa and a compression set of less than 10%. With its excellent high elasticity and creep resistance, it can not only effectively compensate for the assembly tolerance between radiators, but also adapt to thermal expansion and contraction through continuous elastic deformation under long-term thermal cycling conditions, maintaining a stable sealing pressure. This combination of rigid and flexible materials enables the partition 3 to possess both excellent structural durability and dynamic sealing reliability in the harsh engine compartment environment, providing long-term and stable protection against hot air recirculation for the radiator assembly.

[0068] Based on the same inventive concept, this application also provides a vehicle. The vehicle includes the radiator assembly described above.

[0069] The vehicle provided by this utility model adopts the aforementioned radiator assembly. The separator 3 is detachably installed on the high-temperature radiator 1, and the sealing part 303 is made of elastic material and seals against the low-temperature radiator 2. This not only eliminates the dependence on adhesives and avoids the risk of detachment due to adhesive aging and embrittlement, but is also particularly suitable for the high-temperature, high-vibration engine compartment environment. Furthermore, by utilizing the continuous deformation generated by the elastic material under pressure, it automatically adapts to changes in structural gaps caused by manufacturing tolerances, thermal deformation, and vibration, ensuring good airtightness under different operating conditions and fundamentally suppressing hot air backflow and secondary flow phenomena. This application effectively shields the heat dissipation space between the high-temperature radiator 1 and the low-temperature radiator 2 through the main body 301, blocking the hot air backflow path and reducing uncontrolled air leakage caused by gaps between components. This allows the cooling fan to form a more stable and concentrated flow field, significantly improving the ventilation efficiency and heat exchange performance of the overall heat dissipation system.

[0070] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
