Description
Technical Field
[0001] The utility model belongs to the technical field of automobile cooling systems, and relates to a sealing structure between a radiator water chamber and a main plate. Background Art
[0002] At present, the sealing structure used in automobile water tanks is a main plate made of aluminum alloy material, a sealing ring made of EPDM material, and a water chamber structure made of PA66+GF30 material to ensure the sealing performance of the water tank. The conventional main plate sealing groove is a U-shaped groove, and the overall shape of the sealing ring is rectangular or in the shape of a Japanese character or a Chinese character "mu", etc. Its cross-section is usually an elliptical or rectangular structure, and the matching water chamber is a structure with a pressure platform. The conventional pressure platform is flat and smooth without grooves. As Figure 4 shown, the part where the main plate 3 and the water chamber 1 are buckled is a U-shaped groove. When buckling, the sealing ring 2 is first placed in the groove of the main plate and then buckled with the water chamber. This groove can effectively prevent the problem of liquid leakage caused by the displacement of the sealing ring. However, this structure has the following problems:
[0003] 1. The main plate and the water chamber are in clearance fit, which is easy to cause the displacement of the sealing ring, and the displacement condition of the sealing ring cannot be quickly judged. Leakage occurs during the practical use of the product, causing customer complaints.
[0004] 2. The groove part of the main plate occupies a large space and cannot meet the vehicle layout with limited space in some cases;
[0005] 3. Under the same volume, the heat exchange efficiency is insufficient. Content of the Utility Model
[0006] In view of this, the purpose of the utility model is to solve the problem that the sealing ring between the main plate and the water chamber is easy to displace and cause leakage, and provide a sealing structure between a radiator water chamber and a main plate.
[0007] To achieve the above purpose, the utility model provides the following technical solutions:
[0008] A sealing structure between a radiator water chamber and a main plate, including a main plate, a water chamber, and a sealing ring. The main plate is buckled on the water chamber and sealed through the sealing ring. Each of the four corners of the water chamber is provided with an arc-shaped ear. The sealing ring is sleeved on the four arc-shaped ears and fixed by the four arc-shaped ears; a plurality of wedge-shaped brackets are arranged at intervals on the inner wall of the water chamber; the top end of the wedge-shaped bracket extends out of the end face of the water chamber for placing the sealing ring, and this top end is located inside the sealing ring to block the sealing ring and realize the movement limit.
[0009] Further, the height that the top end of the wedge-shaped bracket extends out of the end face of the water chamber for placing the sealing ring is 1-3 mm.
[0010] Further, the end faces of the main plate, the water chamber and the sealing ring in cooperation are all flat surfaces. The thickness of the mating end faces is reduced to reduce the overall volume.
[0011] Further, the wedge-shaped brackets are evenly distributed on both sides in the length direction of the water chamber, and the distance between the wedge-shaped brackets is 3-8 mm.
[0012] Further, the side of the wedge-shaped bracket in contact with the sealing ring is an inclined surface. When buckling, the outer inclined surface of the wedge-shaped bracket plays a guiding role, preventing the displacement of the sealing ring and increasing the strength of the water chamber.
[0013] Further, the sealing ring is an O-shaped sealing ring.
[0014] The beneficial effects of the present utility model are as follows:
[0015] 1. Preventing liquid leakage problems caused by the displacement of the sealing ring: The present utility model uses arc-shaped lugs to fix the sealing ring to ensure that the position of the sealing ring remains unchanged before buckling. The top end of the wedge-shaped bracket extends out of the end face of the water chamber for placing the sealing ring, and the top end is located inside the sealing ring, so that the sealing ring can be effectively blocked, preventing displacement during buckling and use, thereby avoiding liquid leakage problems caused by the displacement of the sealing ring. This design ensures the reliability of the seal and reduces customer complaints and maintenance costs caused by leakage.
[0016] 2. Adapting to the vehicle layout with limited space: The traditional main plate groove part occupies a large space and cannot meet the requirements of some vehicle layouts with limited space. By optimizing the seal structure design, the present utility model does not require a groove, reducing the space occupied by the main plate groove, enabling the radiator to be more flexibly applied to various vehicle layouts, especially suitable for those vehicle designs with a compact space.
[0017] 3. Enhancing the strength of the water chamber and improving product quality: By arranging a number of wedge-shaped brackets distributed at intervals on the inner wall of the water chamber, the structural strength of the water chamber is increased, and it can also play a guiding role during buckling to prevent the displacement of the sealing ring. This design improves the overall mechanical strength and durability of the radiator, making the product quality more stable and reliable.
[0018] 4. Improving the heat dissipation efficiency: Under the same volume, the present utility model optimizes the seal structure, reduces the gap between the main plate and the water chamber, and enhances the heat dissipation efficiency. The improvement of the heat dissipation efficiency helps to improve the working efficiency of the automotive engine, reduce energy consumption and emissions, meeting the requirements of modern vehicles for high efficiency and energy conservation.
[0019] 5. Enhancing customer satisfaction: By solving problems such as the displacement of the sealing ring and liquid leakage, the stability and reliability of the product are improved, making customers more at ease during use, reducing the troubles and maintenance costs caused by product failures, thereby enhancing customer satisfaction. The efficient heat dissipation performance also improves the overall performance of the vehicle, further meeting the needs and expectations of customers.

[0030] Please refer to Figures 1 to 4 , which is a sealing structure between a radiator water chamber and a main plate, including a main plate 2, a water chamber 1, and a sealing ring 3. The main plate 2 is buckled on the water chamber 1 and sealed through the sealing ring 3. An arc-shaped ear 4 is provided at each of the four corners of the water chamber 1. The sealing ring 3 is sleeved on the four arc-shaped ears 4 and fixed by the four arc-shaped ears 4; a plurality of wedge-shaped brackets 5 are arranged at intervals on the inner wall of the water chamber 1; the top end of the wedge-shaped bracket 5 extends out of the end face of the water chamber 1 where the sealing ring 3 is placed, and this top end is located inside the sealing ring 3 to block the sealing ring 3 and achieve moving limit.
[0031] The sealing ring 3 can directly adopt an O-ring. The end faces of the main plate 2, the water chamber 1 and the sealing ring 3 in cooperation are all flat surfaces. The thickness of the mating end faces is reduced to reduce the overall volume.
[0032] The wedge-shaped brackets 5 are evenly distributed on both sides in the length direction of the water chamber 1, and the distance between the wedge-shaped brackets 5 is 3 - 8 mm. The height of the top end of the wedge-shaped bracket 5 extending out of the end face of the water chamber 1 where the sealing ring 3 is placed is 1 - 3 mm. The side of the wedge-shaped bracket 5 in contact with the sealing ring 3 is an inclined surface.

[0033] During installation, first hang the sealing ring 3 on the installation surface of the water chamber 1 and fix it through the arc-shaped ear 4, and then buckle it with the main plate 2. The arc-shaped ear 4 and the wedge-shaped bracket 5 effectively prevent the displacement of the sealing ring 3, thereby avoiding the leakage of the liquid in the water chamber 1.
