Description

Technical Field

[0001] This utility model relates to the field of automotive cooling system technology, specifically to a sealing ring for a dual-pipe radiator for automobiles. Background Technology

[0002] The car radiator is a core component of the engine cooling system, used to dissipate the heat generated by the engine into the air to ensure normal engine operation. For radiators with a thicker core, a dual-row cooling pipe structure is usually used to meet the heat dissipation requirements. In such radiators, where the inlet and outlet are located on the same side, a horizontal baffle is installed in the water chamber to divide the water chamber into two independent chambers to achieve coolant circulation.

[0003] In existing technologies, the seal between the water chamber and the motherboard relies on a sealing ring. However, traditional sealing rings are mostly single-cavity sealing structures, which are difficult to adapt to the dual-cavity separation requirements of a single-sided water chamber, easily leading to leakage between the two cavities. Furthermore, the fixed structural design of traditional sealing rings results in a single flow path within the radiator, preventing flexible adjustments to optimize heat exchange efficiency and limiting the diversity of radiator structural designs. Therefore, there is an urgent need for a sealing ring structure that can reliably separate the water chamber cavities and adapt to diverse flow path designs. This necessitates the design of a sealing ring for automotive dual-pipe radiators to address these issues. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a sealing ring for a dual-pipe radiator in automobiles, which solves the problems of unreliable sealing and simple flow channel design of existing sealing rings, and realizes effective separation of the water chamber and flexible layout of the flow channel.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sealing ring for a dual-pipe radiator in automobiles, used to separate the internal cavity of a single-sided water chamber of the radiator. The sealing ring has an overall H-shaped structure, including first sealing strips at both ends and a second sealing strip located between the first sealing strips at both ends. The first sealing strip has a circular cross-section to ensure a tight seal with the water chamber and the main board. The second sealing strip has an irregular cross-section, with a first arc-shaped notch at the upper end that fits the water chamber. The first arc-shaped notch at the upper end fits tightly with the inner wall of the water chamber. The lower end has... The device has a second arc-shaped notch that matches the motherboard's sealing groove. The lower end of the second arc-shaped notch precisely matches the motherboard's sealing groove. A third arc-shaped notch and a fourth arc-shaped notch are provided on the left and right sides, respectively. The second sealing strip has an irregular cross-section. The third and fourth arc-shaped notches on the left and right sides can adjust the groove fullness after the sealing ring is assembled, ensuring uniform pressure on the sealing surface and preventing leakage. After the sealing ring is combined with the motherboard and the water chamber, it can divide the overall large cavity of the single-sided water chamber into two parallel independent small cavities. The coolant can circulate in the radiator through different flow paths, realizing diversified flow path layout and improving heat exchange efficiency.

[0006] A further improvement of this utility model is that the curvature of both the first arc-shaped notch and the second arc-shaped notch is 90°~120°.

[0007] A further improvement of this utility model is that the third arc-shaped notch and the fourth arc-shaped notch have symmetrical structures.

[0008] A further improvement of this utility model is that the depth of the third arc-shaped notch and the fourth arc-shaped notch is 1 / 3 to 1 / 2 of the thickness of the second sealing strip.

[0009] A further improvement of this utility model is that the two first sealing strips and the second sealing strip are integrally formed and made of high and low temperature resistant rubber.

[0010] A further improvement of this utility model is that the length of the H-shaped structure is adapted to the inner length of the radiator water chamber, and the width is matched with the width of the motherboard sealing groove, which ensures the reliability of the seal and the stability of the structure, and is suitable for the use requirements of dual-row tube radiators.

[0011] A further improvement of this utility model is that: a limiting circular block structure is provided at the corners of both first sealing strips, and the limiting circular block structure can ensure the stability after installation.

[0012] A further improvement of this utility model is that: the side of the second sealing strip has a number of raised dot structures evenly distributed. The purpose of setting the number of raised dot structures is to position the sealing ring in the sealing groove of the motherboard and prevent it from moving after installation.

[0013] 1. Reliable sealing: The design of the H-shaped structure and the irregularly shaped sealing strip effectively separates the two chambers of the water chamber, preventing coolant leakage and solving the problem of poor sealing effect of traditional sealing rings; 2. Flexible flow channels: It can form two independent sealed cavities, which makes the internal flow channels of the radiator more diverse, adapting to different heat dissipation design requirements and improving heat exchange efficiency; 3. High adaptability: The structural design is precisely matched with the motherboard and water chamber of the dual-pipe radiator, making installation convenient and suitable for radiators with thicker cores; 4. Good durability: The one-piece molded high and low temperature resistant rubber material can adapt to the operating temperature changes of the car engine and extend its service life.

Detailed Implementation

[0015] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0016] This embodiment provides a sealing ring for a dual-pipe radiator in automobiles, used to separate the internal cavity of a water chamber on one side of the radiator. The sealing ring 1 has an overall H-shaped structure, including a first sealing strip 2 at both ends and a second sealing strip 3 located in between. The first sealing strip 2 has a circular cross-section, which can ensure a tight seal with the water chamber 11 and the main board 4. The second sealing strip 3 has an irregular shape, with a first arc-shaped notch 5 at the upper end that matches the water chamber 11, a second arc-shaped notch 7 at the lower end that matches the sealing groove 6 of the main board, and a third arc-shaped notch 8 and a fourth arc-shaped notch 9 on the left and right sides, respectively. After the sealing ring 1 is combined with the main board 4 and the water chamber 3, it can be divided into two independent small cavities 10, realizing a diversified flow channel layout and improving heat exchange efficiency.

[0017] The first arc-shaped notch 5 and the second arc-shaped notch 7 both have an arc of 90°~120°, which can increase the sealing contact area by more than 30%, forming a reliable surface seal and blocking the coolant penetration path; the third arc-shaped notch 8 and the fourth arc-shaped notch 9 are symmetrical, ensuring uniform deformation under pressure, avoiding twisting and displacement of the sealing strip caused by local stress concentration, and ensuring consistent sealing pressure in both cavities; the depth of the third arc-shaped notch 8 and the fourth arc-shaped notch 9 is 1 / 3 to 1 / 2 of the thickness of the second sealing strip 2, which can control the assembly compression rate within the optimal range of 25%~35%, preventing sealing gaps and avoiding excessive compression aging, while also buffering vibration impact.

[0018] The two first sealing strips 2 and the second sealing strip 3 are integrally molded structures, made of high and low temperature resistant rubber, eliminating weak points in the splicing, with a temperature resistance range of -40℃ to 150℃, adapting to the extreme temperature of the engine compartment and extending service life; the length of the sealing ring 1 with the H-shaped structure is adapted to the length of the water chamber cavity and the width is matched with the width of the main board sealing groove 6, ensuring precise installation and avoiding assembly gaps, improving structural stability and sealing reliability.

[0019] Each of the two first sealing strips 2 has a limiting circular block structure 12 at its corner. The limiting circular block structure 12 can ensure the stability after installation and prevent the sealing ring 1 from moving or deforming after installation, thus ensuring the stable use of the whole device after installation. The second sealing strip 3 has several protrusion structures 14 evenly distributed on its side. The protrusion structures 14 are provided to position the sealing ring 1 in the motherboard sealing groove 6 and prevent it from moving after installation.

[0020] 1. Installation preparation: Clean the oil, impurities and residual sealant from the motherboard sealing groove 6 and the inner wall of the water chamber 11 of the radiator to ensure that the mating surface is flat and dry; check whether the length and width of the sealing ring 1's T-shaped structure match the inner length of the water chamber 11 and the width of the motherboard sealing groove 6, and confirm that there is no dimensional deviation.

[0021] 2. Sealing ring positioning: Place the H-shaped sealing ring 1 smoothly into the main board sealing groove 6, ensuring that the first sealing strips 2 at both ends are tightly fitted to the inner walls of both ends of the sealing groove 6, and the second sealing strip 3 in the middle is accurately embedded into the partition 13 in the middle of the sealing groove 6 without offset or twisting; press the sealing ring 1 around to make it initially fit against the sealing groove wall.

[0022] 3. Water chamber assembly: Align the radiator water chamber with the assembly positioning pin of the motherboard 4 and slowly snap it together, ensuring that the inner wall of the water chamber is precisely fitted with the first arc-shaped notch 5 at the upper end of the sealing ring 1 and the wall of the sealing groove 6 is precisely fitted with the second arc-shaped notch 7 at the lower end of the sealing ring 1, without any misalignment.

[0023] 4. Tightening and fixing: Tighten the bolts connecting the water chamber 11 and the main board 4 in sequence using a diagonal and uniform tightening method. During the tightening process, you can lightly press the edge of the water chamber to ensure that the sealing ring 1 is fully compressed to the optimal compression rate of 25%~35%.

[0024] 5. Installation and verification: After tightening, check whether the fit between water chamber 11 and motherboard 4 is uniform and whether there are any local protrusions or gaps; inject a small amount of coolant through the radiator inlet, let it stand for 5-10 minutes, and observe whether there is any leakage in the two chambers. After confirming that there are no abnormalities, the installation is completed.

[0025] The above are merely preferred embodiments of this utility model, but do not limit the patent scope of this utility model. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing specific embodiments, or make equivalent substitutions for some of the technical features.
