Description

Technical Field

[0001] This utility model relates to the field of automotive radiator technology, specifically to a sealing device for an anti-fall-off radiator water chamber assembly. Background Technology

[0002] As an indispensable component of a car engine system, the radiator's main function is to effectively cool the coolant in the engine, ensuring stable engine operation. A water-chamber car radiator typically consists of several key parts, including an upper water chamber, a lower water chamber, main fins, and a core, which work together to achieve efficient heat transfer and dissipation.

[0003] In the working process of a car radiator, the high-temperature coolant generated by the engine is first guided to the upper water chamber through the inlet. Then, driven by the water pump, the coolant flows within the radiator core, fully exchanging heat with the external environment to achieve a significant temperature reduction. After this cooling process, the coolant flows into the lower water chamber and is finally discharged from the outlet, returning to the engine for continued recycling.

[0004] Currently, aluminum-plastic composite radiators are highly favored in the market due to their excellent heat dissipation performance and light weight. The water chamber of these radiators is typically manufactured using plastic die-casting technology, ensuring both structural robustness and lightweight design. However, existing technologies mostly rely on sealing rings to achieve the sealing connection between the water chamber and the main fins. But in actual production, this sealing ring installation method faces many challenges: due to the softness and shape of the sealing ring material, as well as various uncertainties during installation, the sealing ring is prone to displacement, making it impossible to accurately fix its position. More seriously, if the sealing ring is not installed correctly or falls off during use, it will directly lead to radiator leakage, affecting the normal cooling of the engine and even causing serious mechanical failures. Summary of the Invention

[0005] The purpose of this utility model is to provide a sealing device for a radiator water chamber assembly that prevents it from falling off. The sealing gasket is placed on the water chamber to strengthen the connection between the two and prevent it from falling off. The operation is simpler and the assembly efficiency is effectively improved.

[0006] To achieve the above objectives, this application proposes a sealing device for an anti-fall radiator water chamber assembly, comprising:

[0007] The main piece has an annular groove on its outer periphery;

[0008] The water chamber has an annular pressing boss extending into the annular groove on its outer periphery, and the bottom surface of the annular pressing boss has a protruding annular limiting block.

[0009] A sealing gasket is arranged inside a cavity formed between the annular groove and the annular compression boss; and the sealing gasket is sleeved on the annular limiting block.

[0010] In one of the embodiments, the annular limiting block comprises a first limiting boss and a second limiting boss, the top surface of the first limiting boss is attached to the bottom surface of the annular compression boss, and the bottom surface of the first limiting boss is attached to the top surface of the second limiting boss.

[0011] In one of the embodiments, the width dimension of the first limiting boss is smaller than that of the second limiting boss.

[0012] In one of the embodiments, the sealing gasket comprises a sealing bottom groove, a first limiting anti-falling compression boss and a second limiting anti-falling compression boss, the first limiting anti-falling compression boss is arranged on both sides of the sealing bottom groove in the vertical direction, and the second limiting anti-falling compression boss is arranged on the top of each first limiting anti-falling compression boss in the inward direction.

[0013] In one of the embodiments, the inner side of the first limiting anti-falling compression boss is attached to the outer side of the second limiting boss in the vertical direction, and the bottom surface of the second limiting anti-falling compression boss is attached to the upper surface of the second limiting boss.

[0014] In one of the embodiments, the width dimension of the annular limiting block gradually increases from the annular compression boss to the bottom surface of the annular groove.

[0015] In one of the embodiments, the sealing gasket comprises a sealing bottom groove and a first limiting anti-falling compression boss, and the first limiting anti-falling compression boss is arranged on both sides of the sealing bottom groove in the inward direction.

[0016] In one of the embodiments, the inner side of the first limiting anti-falling compression boss is attached to the outer side of the annular limiting block.

[0017] In one of the embodiments, the bottom surface of the annular compression boss is provided with a protruding annular limiting block at the center of the edge.

[0018] In one of the embodiments, the sealing bottom groove is arranged on the bottom surface of the annular groove.

[0019] Compared with the prior art, the above technical scheme of the utility model has the advantages that: 1. The sealing gasket is sleeved on the water chamber, which can effectively limit the sealing gasket in the horizontal and vertical directions, thereby maintaining close connection during production and processing and avoiding falling off. This operation is more convenient and improves the assembly efficiency.

[0020] 2. The limiting function of the water chamber structure ensures the accuracy of the position of the sealing gasket, so that it is not easy to deviate, thereby realizing better sealing effect.

[0021] 3. The device improves the finished product qualification rate of the radiator to a certain extent and reduces the repair work. Attached Figure Description
