Description

Technical Field

[0001] This utility model relates to the field of automotive radiator technology, specifically a high-strength corrosion-resistant automotive radiator. Background Technology

[0002] The car radiator is one of the key components of the car cooling system. Its main function is to regulate the engine's operating temperature by dissipating heat, ensuring that the engine operates stably within a suitable temperature range. This is of great significance for improving fuel efficiency, reducing wear, and extending engine life.

[0003] Application number CN202422675919.2 discloses an automotive radiator, including an inlet chamber and an outlet chamber. A plurality of hot water exchange pipes connect the inlet and outlet chambers. Supports are provided at both ends of the inlet and outlet chambers. A plurality of heat exchange fins are arranged parallel to each other between the inlet and outlet chambers. Slides are provided on the sides of both the inlet and outlet chambers, and movable seats are provided on the slides. A support plate is provided between two movable seats. The device includes brushes on the sides of the heat exchange fins that can move on the slides. These movable brushes can brush off dust and lint from the heat exchange fins, reducing the frequency of disassembling the heat exchanger for cleaning and making operation convenient.

[0004] However, in the existing technology and the aforementioned automotive radiators, the overall support capacity is not high when the upper and lower ends of the heat pipe are directly connected to the upper and lower chambers of the device. This makes the heat pipe easy to break when subjected to external force, causing cooling system failure. Utility Model Content

[0005] The purpose of this invention is to provide a high-strength, corrosion-resistant automotive radiator to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A high-strength corrosion-resistant automotive radiator includes two chambers, with multiple heat exchange tubes fixedly connected between the two chambers. One chamber is fixedly connected to an inlet pipe, and the other chamber is fixedly connected to an outlet pipe. A pair of side plates are vertically fixedly connected between the two chambers.

[0008] A reinforcing structure is connected to multiple heat exchange tubes. The reinforcing structure includes two reinforcing plates. Each reinforcing plate has multiple first receiving grooves evenly distributed on it. The reinforcing plates are detachably installed between the two side plates. One side of each heat exchange tube is engaged inside the first receiving groove.

[0009] Preferably, the heat exchange tube is a square tube, and the projection of the first receiving groove on the horizontal plane is a square structure.

[0010] Preferably, the reinforcing structure further includes multiple support blocks and a limiting structure, with a second receiving groove provided between two adjacent first receiving grooves, the two ends of the support block respectively engaging in the two second receiving grooves, and the limiting structure connecting the second receiving groove and the support block.

[0011] Preferably, the limiting structure includes a positioning groove and a positioning block. The positioning groove is formed on the inner wall of the second receiving groove, and the positioning block is fixedly installed on the side of the support block and slidably connected inside the positioning groove.

[0012] Preferably, a contact piece is fixedly installed on one side of the positioning block, and one side of the contact piece is attached to the surface of the heat exchange tube.

[0013] Preferably, heat exchange fins are fixedly installed on the support block.

[0014] Preferably, at least two reinforcing structures are provided, and the at least two reinforcing structures are symmetrically distributed between the two chambers, and adjacent heat exchange plates are fixedly connected.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This utility model connects the heat exchange tubes to the side plate via a detachable reinforcing plate, and sets a first receiving groove on the reinforcing plate to fix the heat exchange tubes, thereby connecting multiple heat exchange tubes into a whole and dispersing external stress. At the same time, the connection between the heat exchange tubes is strengthened by the support block and the limiting structure to prevent fatigue fracture caused by lateral displacement and vibration. Furthermore, the setting of heat exchange fins enhances heat dissipation efficiency. Overall, it not only improves mechanical strength, but also facilitates maintenance and replacement through modular design, effectively avoiding cooling system failure caused by heat exchange tube breakage.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a high-strength corrosion-resistant automotive radiator, comprising two chambers 1, with multiple heat exchange tubes 5 fixedly connected between the two chambers 1, an inlet pipe 2 fixedly connected to one chamber 1, and an outlet pipe 3 fixedly connected to the other chamber 1, a pair of side plates 4 vertically fixedly connected between the two chambers 1, and a reinforcing structure connected to the multiple heat exchange tubes 5, the reinforcing structure comprising two reinforcing plates 6, each reinforcing plate 6 having multiple first receiving grooves 8 evenly distributed on it, the reinforcing plates 6 being detachably installed between the two side plates 4, and one side of each heat exchange tube 5 being engaged inside the first receiving groove 8.

[0024] Please see Figure 1 When the radiator is subjected to external impact or vibration, the reinforcing plate 6 can disperse the stress and prevent the heat exchange tube 5 from being broken due to excessive local stress. In addition, the detachable design of the reinforcing plate 6 facilitates installation and maintenance, reducing manufacturing and maintenance costs. The entire radiator is made of corrosion-resistant materials such as aluminum alloy or coated steel, ensuring that it can be used for a long time in harsh environments without being easily damaged.

[0025] In practical applications, automotive radiators often face challenges such as road vibration, engine heat, and chemical corrosion. This structure forms a rigid frame through the combination of reinforcing plate 6 and side plate 4, similar to a "skeleton" supporting the heat exchange tube 5. The uniform distribution of the first receiving groove 8 ensures that the heat exchange tube 5 is subjected to uniform force, avoiding stress concentration. At the same time, the connection between the chamber 1 and the heat exchange tube 5 can be fixed by welding or sealant to ensure sealing. The position design of the inlet pipe 2 and outlet pipe 3 takes into account fluid dynamics, optimizes coolant flow, and improves heat dissipation efficiency. The side plate 4 not only provides structural support but may also integrate mounting points to facilitate the fixing of the radiator in the engine compartment. Overall, this structure achieves a balance between lightweight and high strength.

[0026] The heat exchange tube 5 is a square tube, and the projection of the first receiving groove 8 on the horizontal plane is a square structure. The reinforcing structure also includes multiple support blocks 10 and a limiting structure. A second receiving groove 9 is opened between two adjacent first receiving grooves 8. The two ends of the support block 10 are respectively engaged in the two second receiving grooves 9. The limiting structure is connected between the second receiving groove 9 and the support block 10.

[0027] Please see Figures 1 to 3 The size of the first receiving groove 8 is slightly larger than the outer diameter of the heat exchange tube 5, allowing for some expansion space during thermal expansion and contraction, while maintaining fixation through a snap-fit ​​mechanism. This design not only improves mechanical strength but also simplifies the assembly process. Workers only need to insert the heat exchange tube 5 into the first receiving groove 8 without the need for additional fasteners.

[0028] The selection of heat exchange tube 5 is based on the specific requirements of automotive radiators. Square tubes have a higher moment of inertia than round tubes for the same cross-sectional area, thus exhibiting stronger bending resistance. The square projection of the first receiving groove 8 is manufactured using CNC stamping or milling processes to ensure consistent dimensions in each groove and avoid tolerance accumulation. The reinforcing plate 6 can be made of high-strength aluminum alloy or stainless steel, which is both lightweight and corrosion-resistant. During radiator operation, coolant flows within the heat exchange tube 5. The right-angled edges of the heat exchange tube 5 may generate slight eddies, enhancing heat transfer. However, this solution primarily addresses the support issue through structural design. Furthermore, the uniform distribution of the first receiving groove 8 means that the spacing between the heat exchange tubes 5 is consistent, which is beneficial for airflow and heat dissipation. If the heat exchange tube 5 needs to be replaced due to damage, the removable reinforcing plate 6 allows for individual tube replacement without disassembling the entire radiator, significantly reducing maintenance costs. Overall, this design improves product maintainability and service life while ensuring performance.

[0029] The limiting structure includes a positioning groove 11 and a positioning block 12. The positioning groove 11 is formed on the inner wall of the second receiving groove 9. The positioning block 12 is fixedly installed on the side of the support block 10 and is slidably connected inside the positioning groove 11.

[0030] Please see Figure 3 The limiting structure prevents the support block 10 from moving or falling out within the second receiving groove 9, maintaining long-term stability. This combined design allows stress to be transferred to the entire reinforcing plate 6 through the support block 10 when the radiator is subjected to impact, avoiding local overload. The material of the support block 10 can be the same as that of the reinforcing plate 6 to ensure consistent thermal expansion coefficients and reduce thermal stress. In practical applications, the support block 10 can also act as a guide, optimizing the airflow path through the heat exchange tube 5 and improving heat dissipation efficiency, but this solution mainly focuses on mechanical reinforcement.

[0031] The shape and size of the support block 10 are customized according to the second receiving groove 9. It is usually a rectangular block with protrusions or grooves at both ends to match the limiting structure. The second receiving groove 9 is located between the first receiving grooves 8, which means that each support block 10 corresponds to two adjacent heat exchange tubes 5, thereby forming continuous support in the lateral direction. The specific form of the limiting structure may include snap-fit, screw or sliding fit, but this solution uses positioning groove 11 and positioning block 12, which simplifies the installation. The number of support blocks 10 can be adjusted according to the size of the radiator. For example, in a large radiator, the density of support blocks 10 can be increased to cope with higher loads. In vibration testing, this design can significantly reduce the amplitude of heat exchange tubes 5 and prevent resonance fracture. In addition, the contact surface between the support block 10 and the heat exchange tube 5 may be coated with thermally conductive adhesive to enhance heat transfer, but this solution does not explicitly require it. Overall, the support block 10 and the limiting structure provide multi-level protection to ensure the reliability of the radiator under harsh road conditions.

[0032] A contact piece 13 is fixedly installed on one side of the positioning block 12. One side of the contact piece 13 is attached to the surface of the heat exchange tube 5. A heat exchange plate 7 is fixedly installed on the support block 10. At least two reinforcing structures are provided. The two reinforcing structures are symmetrically distributed between the two chambers 1, and adjacent heat exchange plates 7 are fixedly connected.

[0033] Please see Figure 4 The contact piece 13 serves as a buffer and heat conductor. When the positioning block 12 is inserted into the positioning groove 11, the contact piece 13 is in close contact with the surface of the heat exchange tube 5, which not only prevents the support block 10 from directly rubbing against the heat exchange tube 5, but also transfers heat through soft materials such as copper or aluminum sheets, enhancing heat exchange efficiency. The heat exchange plate 7 is fixedly installed on the support block 10, expanding the heat dissipation surface area and further optimizing heat dissipation performance. The heat exchange plate 7 can be a finned or finned structure, integrally formed or welded to the support block 10. This design allows the support block 10 to not only serve as a structural component, but also participate in thermal management, achieving the integration of structure and function. In practical applications, the contact piece 13 may be made of a high thermal conductivity material to quickly conduct the heat from the heat exchange tube 5 to the support block 10 and the heat exchange plate 7, and then dissipate it through airflow. However, this solution mainly emphasizes mechanical reinforcement, and the improvement of thermal performance is an additional benefit.

[0034] The thickness and shape of the contact plate 13 can be adjusted according to the size of the heat exchange tube 5. For example, an arc-shaped surface can be used to better fit the surface of the square tube. The contact plate 13 may be kept under constant pressure by a spring or pressure plate mechanism to ensure that it does not loosen under vibration. The design of the heat exchange plate 7 takes aerodynamics into consideration, such as using a wave-shaped or louvered structure to increase turbulence and improve heat dissipation efficiency. The connection method between the support block 10 and the heat exchange plate 7 may include brazing or gluing, but this solution does not specify it. It is recommended to specify it to ensure durability. In high-temperature environments, the material selection of the contact plate 13 and the heat exchange plate 7 is crucial. For example, aluminum alloy can be used to balance thermal conductivity and strength. Overall, this integrated design reduces the number of parts, reduces weight and cost, and improves overall performance. However, it should be noted that the installation of the contact plate 13 should not affect the engagement of the heat exchange tube 5, so the dimensions need to be precisely controlled.
