Description

Technical Field

[0001] This invention belongs to the field of automotive radiator technology, specifically relating to an automotive radiator structure, method, and vehicle with a rock-blocking function. Background Technology

[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.

[0003] The car radiator is a key component of the engine cooling system, and its performance directly affects the engine's heat dissipation efficiency and lifespan. During driving, especially at high speeds or in poor road conditions, stones, gravel, and other debris can easily impact the radiator, causing deformation of the cooling tubes, damage to the cooling fins, or even radiator leaks, severely affecting its normal operation.

[0004] In existing technologies, some radiators use a protective net in front of the radiator to block impacts from foreign objects. However, these protective nets are usually connected to the radiator by bolts or welding, which results in complex installation procedures and inconvenient disassembly. In addition, because bolted connections are prone to loosening and welding can cause thermal damage to the radiator body, the protective net is not securely fixed and is prone to falling off under long-term vehicle vibration conditions, thus failing to provide effective protection continuously. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a car radiator structure, method, and vehicle with a stone-blocking function, solving the problems of insecure fixing, inconvenient disassembly and assembly, and easy detachment of the radiator protection device under long-term vehicle vibration conditions in the prior art.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: In a first aspect, the present invention provides a car radiator structure with a stone-blocking function, comprising a radiator and a stone-blocking mesh clipped onto the radiator. The radiator includes two cooling liquid collection pipes, and multiple cooling flat tubes are arranged in parallel between the two cooling liquid collection pipes. There is a gap between two adjacent cooling flat tubes. Multiple fixing clips are provided at both ends of the stone-blocking mesh. The fixing clips are inserted between two adjacent cooling flat tubes and pressed and fixed with the cooling flat tubes. The end of the fixing clip away from the stone-blocking mesh is engaged with the edge of the cooling flat tube.

[0007] As a further implementation, the rock-blocking net includes a fixed frame, grid strips, and reinforcing ribs; the grid strips are disposed in the fixed frame, and both ends of the grid strips are fixedly connected to the inner wall of the fixed frame; the reinforcing ribs are disposed in the fixed frame, both ends of the reinforcing ribs are fixedly connected to the inner wall of the fixed frame, and the middle part of the reinforcing ribs is fixedly connected to the grid strips; the length direction of the grid strips is perpendicular to the length direction of the reinforcing ribs.

[0008] As a further implementation, there are multiple grid strips arranged in parallel with adjacent grid strips having the same spacing; at least two reinforcing ribs are provided and are evenly arranged in the fixed frame; the fixed frame is a square frame, and the fixed frame, reinforcing ribs, and grid strips are integrally cast or welded together.

[0009] As a further implementation, the fixing member includes a first limiting part, a second limiting part, and a third limiting part; the first limiting part is fixedly installed on the fixing frame, and the second limiting part is fixedly provided at one end of the first limiting part along the width direction of the fixing frame, the length direction of the second limiting part is perpendicular to the plane formed by the fixing frame, and the third limiting part is provided on the second limiting part.

[0010] As a further implementation, the second limiting part is a columnar structure, with one end fixedly connected to the first limiting part and the other end provided with a hook, so that the hook is stuck on the side of the heat dissipation flat tube away from the fixed frame.

[0011] As a further implementation, a bending fixing bracket is also provided between the second limiting part and the third limiting part. The middle part of the bending fixing bracket is fixedly connected to the second limiting part, one end of which is fixedly connected to the fixing frame, and the other end is fixedly connected to the third limiting part. The third limiting part has an arc-shaped structure and protrudes away from the second limiting part. When the third limiting part is pressed against the adjacent heat dissipation flat tube, it can effectively prevent the hook from detaching from the heat dissipation flat tube.

[0012] As a further implementation, the two heat dissipation collection pipes are connected to the multiple heat dissipation flat pipes; multiple fixed mounting brackets are provided on the heat dissipation collection pipes, and the fixed mounting brackets are fixedly connected or snap-fitted to the heat dissipation collection pipes. The fixed mounting brackets are made of steel plates, and their shape is adapted to the heat dissipation collection pipes and the installation structure.

[0013] As a further implementation, several heat dissipation fins are provided on the multiple heat dissipation flat tubes.

[0014] Secondly, the present invention also provides a method for using a car radiator structure with a stone-blocking function, comprising the following steps: aligning the fixing clip of the stone-blocking mesh with the gap between two adjacent heat dissipation flat tubes on the radiator; inserting the fixing clip into the gap; pressing and fixing the fixing clip and the heat dissipation flat tube by the third limiting part; and engaging the end of the fixing clip away from the stone-blocking mesh with the edge of the heat dissipation flat tube by the hook at the end of the second limiting part, thereby completing the fixed installation of the stone-blocking mesh and the radiator.

[0015] Thirdly, the present invention also provides a vehicle, including an engine and the aforementioned automobile radiator structure with a rock-blocking function, wherein the automobile radiator structure is installed in the engine compartment for cooling the engine.

[0016] Compared with the prior art, the advantages and positive effects of this invention are: This invention achieves rapid snap-fit ​​installation between the retaining mesh and the radiator by inserting a fixing clip into the gap between adjacent heat dissipation flat tubes and pressing it tightly against the tubes. Utilizing the inherent gap between adjacent heat dissipation flat tubes in the radiator's structure as the insertion channel for the fixing clip, no additional modifications or openings are required to the radiator body, thus avoiding damage to the radiator's structural integrity. Furthermore, no additional mounting brackets or fixing seats are needed. The entire installation process requires no bolt tightening tools or welding equipment; it can be completed simply by manual pushing force. The installation procedure is simple and convenient.

[0017] This invention uses a fixing clip to engage with the edge of the heat dissipation flat tube at the end furthest from the stone barrier. This creates a hook-like constraint on top of the insertion and clamping. The clamping force and the clamping force work together on the heat dissipation flat tube, forming a double fixing structure of clamping and clamping. This structure can simultaneously resist the outward pushing force generated when the stone barrier is impacted and the loosening tendency caused by long-term vehicle vibration. It effectively prevents the stone barrier from falling off during use, and the fixing reliability is significantly better than that of a single bolt fixing method. At the same time, it avoids the problem of heat damage to the heat dissipation flat tube and heat dissipation fins caused by welding heat in welding fixing methods. Attached Figure Description

[0021] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0022] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, unless otherwise expressly indicated by the invention, the singular form is also intended to include the plural form. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof. Example 1 This embodiment proposes a car radiator structure with a rock-blocking function, such as... Figure 1 - Figure 7 As shown, the radiator 1 and the retaining mesh 2 are fixed together by the fixing clip 24 to achieve the synergy of quick installation and reliable fixation between the radiator and the retaining mesh.

[0023] like Figure 1 - Figure 4 , Figure 6As shown, the automotive radiator structure of this embodiment includes a radiator 1 and a retaining mesh 2 snapped onto the radiator 1. The radiator 1 is a heat exchange device of the engine cooling system, consisting of two cooling manifolds 11 and multiple cooling flat tubes 12. The two cooling manifolds 11 are located at the left and right ends of the radiator 1, respectively. Multiple cooling flat tubes 12 are arranged parallel to each other between the two cooling manifolds 11. The multiple cooling flat tubes 12 are evenly arranged along the length of the cooling manifolds 11, with gaps between adjacent cooling flat tubes 12. The gaps between adjacent cooling flat tubes 12 are inherent spaces formed by the structure of the radiator 1 itself, directly serving as insertion channels for the fixing clips 24. The retaining mesh 2 can be snapped onto and installed without modifying the radiator 1.

[0024] The retaining mesh 2 is flat in shape, with multiple fixing clips 24 at both ends. The fixing clips 24 are positioned to correspond to the inner side of the heat dissipation collection pipe 11, which is fixedly connected to the heat dissipation flat pipe 12. The retaining mesh 2 is connected to the radiator 1 through the fixing clips 24. During installation, the fixing clips 24 are inserted into the gap between two adjacent heat dissipation flat pipes 12 and pressed and fixed with the heat dissipation flat pipes 12; the end of the fixing clip 24 away from the retaining mesh 2 is engaged with the edge of the heat dissipation flat pipe 12 to form a hook-type fixation.

[0025] During installation, the operator holds the retaining mesh 2 and moves it to the front of the radiator 1, making the plane of the retaining mesh 2 roughly parallel to the front of the radiator 1. The operator aligns the fixing clip 24 with the gap between adjacent heat dissipation flat tubes 12 and pushes the retaining mesh 2 towards the radiator 1, causing the fixing clip 24 to insert into the gap. Continued pushing force causes the fixing clip 24 to form a pressing contact with the heat dissipation flat tube 12. The end of the fixing clip 24 away from the retaining mesh 2 extends beyond the edge of the heat dissipation flat tube 12, forming a snap-fit ​​with the edge of the heat dissipation flat tube 12, completing the fixed installation of the retaining mesh 2. The entire installation process requires no tools and can be completed solely by manual pushing force, making the operation simple and quick.

[0026] The action of inserting the fixing clip 24 into the gap of the heat dissipation flat tube 12 and pressing it together with the action of the remote end snapping, forms a double fixing relationship of pressing and snapping, which is reliable. It avoids the problem of bolt connection loosening due to long-term vibration in the bolt fixing method. At the same time, it also avoids the problem of heat damage to the heat sink 1 body caused by high temperature welding in the welding fixing method, especially the heat dissipation flat tube 12 and heat dissipation fins 13. When disassembling, you only need to pull the retaining mesh 2 outward to overcome the snapping force of the fixing clip 24 to remove the retaining mesh 2. It is easy to disassemble and assemble, which is conducive to daily maintenance.

[0027] Under normal driving conditions, the radiator 1 is subjected to continuous vibrations from the road surface. Because the fixing clip 24 employs both clamping and snap-fit ​​fixing methods, the two fixing forces work together to prevent detachment caused by vibration. Even on bumpy roads or at high speeds, the stone barrier 2 maintains a stable connection with the radiator 1, continuously providing protection.

[0028] The retaining mesh 2 includes a fixing frame 21, grid strips 22, and reinforcing ribs 23. The fixing frame 21 is the outer frame of the retaining mesh 2, and its overall shape is a square frame structure. Its external dimensions are adapted to the shape of the front of the radiator 1, ensuring that the retaining mesh 2 can completely cover the front area of ​​the radiator 1 after installation, achieving comprehensive protection for the radiator 1 without leaving any blind spots. The fixing frame 21 provides the overall structural rigidity of the retaining mesh 2. The fixing clips 24 are fixedly installed at both ends of the fixing frame 21, and the retaining mesh 2 is connected to the radiator 1 through the fixing frame 21.

[0029] The grid strips 22 are disposed within the internal space of the fixed frame 21. Multiple grid strips 22 are arranged parallel to each other, with equal spacing between adjacent strips, forming a uniformly distributed parallel grid array. Both ends of the grid strips 22 are fixedly connected to the inner wall of the fixed frame 21, ensuring the grid strips 22 are securely tensioned within the frame 21. The main function of the grid strips 22 is to block the passage of foreign objects such as stones. The spacing design must strike a balance between blocking capacity and ventilation resistance; too small a spacing increases ventilation resistance and affects heat dissipation efficiency, while too large a spacing reduces the protective effect. Of course, in other embodiments, the spacing of the grid strips can be set to non-uniform spacing, determined according to different working conditions or environmental requirements, achieving effective protection while ensuring ventilation.

[0030] Reinforcing ribs 23 are also provided within the internal space of the fixed frame 21. At least two reinforcing ribs 23 are provided, with multiple reinforcing ribs 23 evenly distributed within the fixed frame 21. The two ends of each reinforcing rib 23 are fixedly connected to the inner wall of the fixed frame 21, and the middle of each reinforcing rib 23 is fixedly connected to the grid strip 22, forming a cross-support relationship. The length direction of the reinforcing rib 23 is perpendicular to the length direction of the grid strip 22, forming an orthogonal grid structure.

[0031] The fixed frame 21, reinforcing ribs 23, and grid strips 22 are integrally molded or welded together, forming an inseparable whole structure. The integral molding process makes the connection strength between the three components much higher than that of separate assembly methods, eliminating the risk of loosening or falling off between the components and ensuring the structural integrity and stability of the stone retaining net 2 during long-term use.

[0032] The orthogonal grid structure formed by the perpendicular arrangement of the grid strips 22 and the reinforcing ribs 23 has excellent impact resistance. When stones or gravel impact the stone retaining net 2 at high speed, the impact force first acts on the impacted grid strips 22. At this time, the reinforcing ribs 23, through their fixed connection points with the grid strips 22 in the middle, provide lateral support to the impacted grid strips 22 in the vertical direction, effectively limiting the bending deformation of the grid strips 22 in the direction of the impact force. At the same time, the impact force is distributed and transmitted to multiple reinforcing ribs 23 through the intersection nodes of the grid strips 22 and the reinforcing ribs 23, and then transmitted from the reinforcing ribs 23 to the fixed frame 21, and finally distributed to the heat dissipation flat tubes 12 through the fixing clips 24. This multi-path force transmission mechanism disperses the single-point impact force to the entire stone retaining net 2 structure, greatly reducing local stress concentration and improving the overall impact resistance and service life of the stone retaining net 2.

[0033] The overall rigid structure of the fixing frame 21 also provides a stable reference platform for the installation of the fixing clips 24. Due to the sufficient rigidity of the fixing frame 21, the multiple fixing clips 24 fixed at both ends of the fixing frame 21 can maintain accurate relative positions. When installing the retaining wall 2, the overall positioning function of the fixing frame 21 allows the multiple fixing clips 24 to be simultaneously aligned with the corresponding gaps in the heat dissipation flat tubes 12, eliminating the need for individual adjustments and significantly improving installation efficiency.

[0034] like Figure 1 , Figure 4 - Figure 7 As shown, the fixing clip 24 includes a first limiting part 241, a second limiting part 242, and a third limiting part 243. The three limiting parts each perform their respective functions and work together to achieve multiple fixation of the heat dissipation flat tube 12 by the fixing clip 24.

[0035] The first limiting part 241 is a connecting member between the fixing clip 24 and the fixing frame 21, and is fixedly installed on the fixing frame 21. The first limiting part 241 firmly anchors the fixing clip 24 to the fixing frame 21, ensuring the positional accuracy and connection stability of the fixing clip 24 relative to the fixing frame 21. A second limiting part 242 is fixedly provided at one end of the first limiting part 241 along the width direction of the fixing frame 21, so that the second limiting part 242 extends from the edge of the fixing frame 21 toward the heat sink 1.

[0036] The second limiting part 242 is a columnar structure and is the main component for inserting the fixing clip 24 into the gap of the heat dissipation flat tube 12. One end of the second limiting part 242 is fixedly connected to the first limiting part 241, and the other end is provided with a hook. The length direction of the second limiting part 242 is perpendicular to the plane formed by the fixing frame 21, that is, the second limiting part 242 extends perpendicularly to the plane of the retaining mesh 2 towards the radiator 1, so that the second limiting part 242 can be inserted into the gap between two adjacent heat dissipation flat tubes 12 in a direction perpendicular to the arrangement surface of the heat dissipation flat tubes 12 during installation, and the columnar structure can pass through the gap smoothly without getting stuck.

[0037] The hook at the end of the second limiting part 242 is a structure for locking and fixing. When the second limiting part 242 is fully inserted into the gap of the heat dissipation flat tube 12, the hook passes over the end edge of the heat dissipation flat tube 12 and locks onto the side of the heat dissipation flat tube 12 away from the fixing frame 21, that is, it locks onto the back of the heat dissipation flat tube 12. A locking engagement is formed between the hook and the edge of the heat dissipation flat tube 12, generating a constraint force that prevents the fixing clip 24 from retracting away from the radiator 1, thereby preventing the retaining mesh 2 from detaching from the radiator 1 when subjected to outward pulling force.

[0038] A third limiting part 243 is provided on the second limiting part 242. The third limiting part 243 has an arc-shaped structure and protrudes away from the second limiting part 242, that is, the arc-shaped protrusion faces the adjacent heat dissipation flat tube 12. When the retaining net 2 is installed in place, the arc-shaped protrusion of the third limiting part 243 presses against the side of the adjacent heat dissipation flat tube 12 facing the fixing frame 21. The arc-shaped structure of the third limiting part 243 makes it form a line contact or surface contact with the heat dissipation flat tube 12, with a large contact area and uniform distribution of pressing force, which will not cause local stress concentration damage to the heat dissipation flat tube 12. The front pressing force applied by the third limiting part 243 to the heat dissipation flat tube 12, together with the snapping force of the hook at the end of the second limiting part 242 to the back of the heat dissipation flat tube 12, acts on the heat dissipation flat tube 12 to form a double fixation of pressing and snapping, making the connection between the fixing clip 24 and the heat dissipation flat tube 12 extremely firm and difficult to loosen or fall off under the action of external force.

[0039] A bent fixing bracket is also provided between the second limiting part 242 and the third limiting part 243. The bent fixing bracket is an auxiliary component that enhances the structural stability of the fixing clip 24. Its middle part is fixedly connected to the second limiting part 242, providing lateral support for the second limiting part 242. One end of the bent fixing bracket is fixedly connected to the fixing frame 21, reinforcing the root of the second limiting part 242 and preventing the second limiting part 242 from deflecting relative to the fixing frame 21 when subjected to force. The other end of the bent fixing bracket is fixedly connected to the third limiting part 243, connecting the third limiting part 243, the second limiting part 242, and the fixing frame 21 to form a triangular support structure. The triangular structure has excellent geometric stability and can maintain its shape under force in all directions. Therefore, the setting of the bent fixing bracket improves the stability of the second limiting part 242 and the third limiting part 243 in the working state.

[0040] Under normal vehicle operating conditions, the radiator 1 is continuously subjected to vibration excitation from the road surface. Under the action of vibration, the force state of each part of the fixing clip 24 is as follows: The arc-shaped structure of the third limiting part 243 has a certain elasticity, which can adapt to the small displacement generated by the heat dissipation flat tube 12 during vibration, and always maintains a tight contact with the heat dissipation flat tube 12, and will not detach from the heat dissipation flat tube 12 due to vibration; the hook at the end of the second limiting part 242 is constrained by the edge of the back of the heat dissipation flat tube 12, and the vibration will not cause the hook to withdraw in the insertion direction; the triangular support structure of the bending fixing bracket ensures that the second limiting part 242 does not bend or deform during vibration, thereby ensuring that the hook is always in the correct locking position; the arc-shaped protrusion of the third limiting part 243 applies a continuous pressing force to the heat dissipation flat tube 12, and further locks the hook under the action of torque, making it more difficult for the hook to detach from the back of the heat dissipation flat tube 12.

[0041] The first limiting part 241, the second limiting part 242, the third limiting part 243, and the bending fixing bracket cooperate with each other to form a multi-fixing mechanism of pressing and locking: the first limiting part 241 fixes the fixing clip 24 to the fixing frame 21, providing an installation base; the second limiting part 242 is inserted into the gap of the heat dissipation flat tube 12 and is fixed by the end hook; the third limiting part 243 presses the heat dissipation flat tube 12 from the front, forming a two-way locking with the hook; the bending fixing bracket is responsible for enhancing the structural stability of the second limiting part 242 and the third limiting part 243, preventing deformation failure under vibration conditions.

[0042] The radiator 1 includes a mounting bracket on the cooling manifold 11 and cooling fins 13 arranged on the cooling flat tubes 12. Two cooling manifolds 11 are located at opposite ends of the radiator 1, and are interconnected with multiple cooling flat tubes 12, forming a complete coolant circulation channel. After the heat generated by the engine is transferred to the coolant, the high-temperature coolant flows in from one cooling manifold 11 and is evenly distributed to the multiple cooling flat tubes 12 through the manifold's distribution function. The coolant flows along the pipe direction within the cooling flat tubes 12, transferring heat to the outside through the thin walls of the tubes, exchanging heat with the air flowing through the radiator 1, and gradually decreasing the coolant temperature. After heat exchange, the coolant collects from the multiple cooling flat tubes 12 into another cooling manifold 11, and then returns to the engine through the pipes, completing one complete cooling cycle. The liquid distribution and collection functions of the heat dissipation pipe 11 ensure that the coolant is evenly distributed in the multiple heat dissipation flat pipes 12, avoids local overheating, and improves the overall heat dissipation uniformity.

[0043] Multiple mounting brackets are provided on the radiator manifold 11. These mounting brackets are connecting components that secure the radiator 1 to the vehicle's engine compartment. The mounting brackets are fixedly connected to the radiator manifold 11 or snap-fitted together, ensuring a stable and reliable connection. The mounting brackets are made of steel plate, which possesses sufficient strength and rigidity to withstand the weight of the radiator 1 and vibration loads during operation, ensuring accurate and secure installation of the radiator 1 within the engine compartment. The shape of the mounting brackets is specifically designed based on the shape of the radiator manifold 11 and the installation structure within the engine compartment, ensuring a good fit with both and guaranteeing installation accuracy and stability. The mounting brackets typically have mounting holes or slots, which are used to connect to the mounting brackets in the engine compartment via bolts or snap-fits, achieving reliable overall fixation of the radiator 1.

[0044] Multiple heat dissipation flat tubes 12 are equipped with several heat dissipation fins 13. The heat dissipation fins 13 are components that improve the heat exchange efficiency of the radiator 1. They are fixedly connected to the heat dissipation flat tubes 12, typically using mechanical expansion or brazing to achieve a tight bond, ensuring good thermal conductivity between the heat dissipation flat tubes 12 and the heat dissipation fins 13. The heat dissipation fins 13 are evenly distributed along the length of the heat dissipation flat tubes 12, forming channels for airflow between adjacent fins 13. The sheet-like structure of the heat dissipation fins 13 significantly increases the contact area between the radiator 1 and the air, enabling efficient heat exchange within a limited volume. When air flows through the radiator 1, it enters the channels between adjacent heat dissipation fins 13, directly contacting the outer walls of the heat dissipation fins 13 and the heat dissipation flat tubes 12, carrying away heat and achieving efficient heat dissipation.

[0045] The retaining mesh 2 is secured in the gap of the heat dissipation flat tube 12 by the fixing clip 24, located at the front of the radiator 1, forming the first protective barrier. The heat dissipation fins 13 are in close contact with the outer wall of the heat dissipation flat tube 12, located in the middle layer of the radiator 1, forming a heat dissipation structure layer. The heat dissipation flat tube 12 is located inside the radiator 1, forming a coolant channel layer.

[0046] When the vehicle is in motion, stones, gravel, and other foreign objects splashed from the road surface fly at high speed toward the radiator 1, where they are first intercepted by the stone-blocking mesh 2. The orthogonal grid structure formed by the grid strips 22 and reinforcing ribs 23 of the stone-blocking mesh 2 can effectively block larger stones, preventing them from passing through the grid gaps to reach the heat dissipation fins 13 and heat dissipation flat tubes 12, thereby protecting the core heat exchange components of the radiator 1 from impact damage. For smaller particles that can pass through the grid gaps of the stone-blocking mesh 2, the dense arrangement of the heat dissipation fins 13 can provide a secondary blocking effect, further reducing the impact of foreign objects on the heat dissipation flat tubes 12.

[0047] The mesh gaps of the retaining mesh 2 provide ample airflow channels, allowing air to pass smoothly through the retaining mesh 2 and enter the channels between the heat dissipation fins 13 for heat exchange with the heat dissipation flat tubes 12. The retaining mesh 2 generates minimal additional resistance to airflow and does not significantly reduce the airflow through the radiator 1. Therefore, the heat dissipation efficiency is essentially unaffected, achieving a synergistic unity of protection and heat dissipation functions.

[0048] After the radiator 1 is fixed in the engine compartment by the mounting bracket, the retaining mesh 2 is also fixed in the engine compartment along with the radiator 1 through the snap-fit ​​connection between the retaining clip 24 and the cooling flat tube 12. This eliminates the need for separate fixing points or mounting brackets for the retaining mesh 2, simplifying the overall installation structure and reducing the number of parts and installation steps. When cleaning or maintenance of the radiator 1 is required, simply remove the retaining mesh 2 from the radiator 1 for easy cleaning of the front of the radiator 1. After maintenance, the retaining mesh 2 can be reinstalled, making the operation convenient.

[0049] Example 2 This embodiment provides an installation method for an automotive radiator structure with a stone-blocking function. Before performing the installation operation, it is necessary to confirm that the radiator 1 has been correctly installed and fixed in the engine compartment by the fixed mounting bracket, the front of the radiator 1 faces the front of the vehicle, the gaps between each heat dissipation flat tube 12 are clean and free of foreign objects, and the fixing clips 24 of the stone-blocking net 2 are intact and undamaged.

[0050] The installation steps are as follows: The operator holds both sides of the fixing frame 21 of the retaining mesh 2 and moves it to the front of the radiator 1, ensuring that the plane of the fixing frame 21 is parallel to the front of the radiator 1. Visually inspecting the fixing frame 21, the operator aligns the multiple fixing clips 24 at both ends with the gaps between adjacent heat dissipation flat tubes 12 on the radiator 1. Because the fixing frame 21 is a square frame, its overall shape matches the front shape of the radiator 1, and the multiple fixing clips 24 are evenly distributed at both ends of the fixing frame 21, the alignment operation is relatively intuitive, allowing the operator to quickly determine whether the fixing clips 24 are aligned with the gaps. The overall rigid structure of the fixing frame 21 plays a crucial positioning role, ensuring that multiple fixing clips 24 can be aligned with the corresponding gaps simultaneously, avoiding the tedious operation of aligning them one by one.

[0051] After alignment and positioning, the operator smoothly pushes the retaining mesh 2 towards the radiator 1, causing the second limiting part 242 of the fixing clip 24 to enter the gap between adjacent heat dissipation flat tubes 12 in a direction perpendicular to the arrangement surface of the heat dissipation flat tubes 12. The columnar cross-sectional dimensions of the second limiting part 242 are adapted to the width of the gap between the heat dissipation flat tubes 12, allowing it to pass through the gap smoothly without getting stuck. During insertion, the operator should maintain a uniform pushing force to avoid uneven force causing the fixing frame 21 to tilt, which would affect the insertion effect. As the second limiting part 242 gradually penetrates into the gap, the hook at the end of the second limiting part 242 also moves closer to the back of the heat dissipation flat tube 12.

[0052] As the retaining mesh 2 continues to be pushed towards the radiator 1, the arc-shaped protrusion of the third limiting part 243 of the fixing clip 24 begins to contact the front of the heat dissipation flat tube 12. Because the third limiting part 243 has an arc-shaped structure, its initial contact with the heat dissipation flat tube 12 is a smooth line contact. As the pushing force increases, the contact area gradually increases, and the third limiting part 243 forms an elastic pressing effect on the heat dissipation flat tube 12. The arc-shaped elastic structure of the third limiting part 243 can adaptively compensate for minor unevenness on the surface of the heat dissipation flat tube 12, ensuring a uniform distribution of the pressing force and forming a stable and reliable pressing contact. At this time, the triangular support of the bent fixing bracket on the second limiting part 242 ensures that the second limiting part 242 will not bend or deform when subjected to the reaction force transmitted from the third limiting part 243, maintaining the stability of the overall structure of the fixing clip 24.

[0053] As the operator continues to apply force until the third limiting part 243 is fully pressed against the front of the heat dissipation flat tube 12, the hook at the end of the second limiting part 242 has completely passed the end edge of the heat dissipation flat tube 12 and entered the back area of ​​the heat dissipation flat tube 12. The hook-shaped structure of the hook engages with the back edge of the heat dissipation flat tube 12, forming a snap-fit. At this time, the third limiting part 243 applies a pressing force to the heat dissipation flat tube 12 from the front, and the hook applies a snap-fit ​​force to the edge of the heat dissipation flat tube 12 from the back. The two directions are opposite, together forming a bidirectional clamping and locking state for the heat dissipation flat tube 12, completing the fixed installation of the retaining mesh 2 and the radiator 1.

[0054] After installation, gently pull the retaining mesh 2 outward to feel the locking resistance of the fixing clip 24. If the resistance is obvious and the retaining mesh 2 does not move significantly, it means that the installation is in place. Check the fit between the retaining mesh 2 and the front of the radiator 1 to confirm that there is no obvious gap between the fixing frame 21 and the front of the radiator 1. Check the installation status of each fixing clip 24 one by one to confirm that all fixing clips 24 have been correctly inserted and locked in place.

[0055] The disassembly operation is the reverse of the installation operation. The operator holds both sides of the fixing frame 21 of the retaining mesh 2 and pulls it evenly away from the radiator 1. The pulling force first overcomes the elastic clamping force of the third limiting part 243 on the heat dissipation flat tube 12, causing the third limiting part 243 to disengage from the front of the heat dissipation flat tube 12. Continuing to apply the pulling force, the hook at the end of the second limiting part 242 is blocked by the edge of the back of the heat dissipation flat tube 12. Under the action of the pulling force, the hook-like structure gradually disengages from the edge of the back of the heat dissipation flat tube 12, completing the release of the latch. Subsequently, the second limiting part 242 exits from the gap in the heat dissipation flat tube 12, and the retaining mesh 2 is completely separated from the radiator 1, completing the disassembly. The entire disassembly process also requires no tools and can be completed by a single person, making it simple to operate, greatly improving maintenance efficiency and reducing maintenance costs.

[0056] Example 3 This embodiment provides a vehicle, including an engine and radiator structure. The vehicle can be a passenger car, commercial vehicle, SUV, or other type of motor vehicle. The vehicle includes an engine compartment, in which the engine is mounted. The engine is the power source of the vehicle and continuously generates a large amount of heat during normal operation. If the heat cannot be dissipated in time, the engine temperature will continue to rise, leading to engine overheating, causing serious consequences such as performance degradation, component damage, or even engine failure. Therefore, an efficient and reliable cooling system is crucial for ensuring the normal operation of the engine.

[0057] The car radiator structure with stone-blocking function is installed in the engine compartment, located in front of the engine, adjacent to the front grille. The radiator 1 is connected and fixed to the mounting bracket in the engine compartment via a fixed mounting bracket on the radiator manifold 11. The shape of the fixed mounting bracket is adapted to the shape of the radiator manifold 11 and the structure of the engine compartment mounting bracket. During installation, the mounting holes on the fixed mounting bracket are aligned with the corresponding holes on the engine compartment mounting bracket, and bolts are tightened to achieve a stable installation of the radiator 1 in the engine compartment. The fixed mounting bracket is made of steel plate, possessing sufficient structural strength to reliably support the weight of the radiator 1 and withstand vibration and impact loads during vehicle operation, ensuring that the radiator 1 maintains the correct installation position under various operating conditions.

[0058] After the radiator 1 is installed, its cooling manifold 11 is connected to the engine's coolant outlet and inlet via coolant hoses, forming a complete coolant circulation loop. When the engine is running, the coolant absorbs heat inside the engine and its temperature rises. The high-temperature coolant flows through the coolant hoses into the cooling manifold 11 at the inlet end of the radiator 1, where it is evenly distributed into multiple cooling flat tubes 12 by the distributing action of the cooling manifold 11. As the coolant flows within the cooling flat tubes 12, heat is conducted through the thin walls of the tubes to the cooling fins 13, which then transfer the heat to the flowing air, achieving efficient heat exchange. The cooled coolant then collects from the cooling flat tubes 12 back into the cooling manifold 11 at the outlet end and returns to the engine through the coolant hoses, completing the cooling cycle and continuously maintaining the engine within a suitable operating temperature range.

Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solutions of the present invention are still within the scope of protection of the present invention.
