Description

Technical Field

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

[0002] A car radiator consists of three parts: the inlet chamber, the outlet chamber, and the radiator core. Coolant flows inside the radiator core, while air passes outside. Hot coolant cools as it dissipates heat to the air, while the cool air warms up by absorbing the heat released by the coolant. There are two main types of car radiators: aluminum and copper. Aluminum radiators are used in passenger cars, while copper radiators are used in large commercial vehicles. The materials and manufacturing technology for car radiators have developed rapidly. Aluminum radiators, with their significant advantages in lightweight materials, are gradually replacing copper radiators in passenger cars and light vehicles. Meanwhile, copper radiator manufacturing technology and processes have made considerable progress. Brazed copper radiators have significant advantages in engine radiators for buses, construction machinery, and heavy trucks. In foreign countries, passenger cars mostly use aluminum radiators, primarily for environmental reasons.

[0003] Currently, during vehicle operation, due to pressure changes inside the water pipes and vehicle vibrations, the seals at the joints can easily loosen. A large amount of air can enter the radiator, creating air resistance. This air resistance hinders the normal circulation of coolant, preventing it from effectively transferring heat generated by the engine to the radiator surface for dissipation. This causes the engine temperature to rise continuously, affecting engine power output and lifespan, and also reducing fuel economy. Utility Model Content

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0023] Please see Figures 1-4 A high-sealing automotive radiator includes: a connecting pipe 2, a water pipe 6 inside one end of the connecting pipe 2, a rubber ring 11 inside the water pipe 6, a spring 18 inside the rubber ring 11, a fixing seat 16 connected to one side of the connecting pipe 2, a limiting protrusion 14 connected to one end of the fixing seat 16, a sealing groove 15 inside the fixing seat 16, a guide groove 12 inside the connecting pipe 2, a radiator 1 connected to one end of the connecting pipe 2, a sealing protrusion 9 fitted inside the sealing groove 15, a sealing rubber ring 10 at one end of the sealing protrusion 9, a plug socket 17 fixedly connected to one end of the sealing protrusion 9, and a limiting groove 13 inside one end of the plug socket 17.

[0024] In a further embodiment of this utility model, by aligning the fixing seat 16 connected to one side of the connecting pipe 2 with the plug seat 17, the rubber ring 11 provided inside the water pipe 6 and the spring 18 inside the rubber ring 11 provide elastic support to make the rubber ring 17 more flexible. When the water pipe 6 is connected to the connecting pipe 2, the rubber ring 11 can tightly fit the inner wall of the water pipe 6 against the inner wall of the connecting pipe 2, effectively preventing coolant leakage. Between the fixing seat 16 and the plug seat 17, the sealing groove 15 fits into the sealing protrusion 9, and the sealing protrusion 9 pushes the sealing rubber ring 10 into the interior of the sealing groove 15, forming another sealing barrier to prevent the coolant of the radiator 1 from seeping out from the connection, greatly reducing the risk of coolant leakage and ensuring normal coolant circulation. The limiting protrusion 14 at one end of the fixing seat 16 cooperates with the limiting groove 13 on one side of the plug seat 17. When the limiting protrusion 14 fits into the limiting groove 13, the installation can be quickly and accurately aligned, reducing the difficulty of installation, reducing installation time and labor costs. The guide groove 12 inside the connecting pipe 2 allows the coolant to be guided to form a spiral flow inside the connecting pipe 2. This flow mode is more likely to generate turbulence. In the turbulent state, the mixing between the various parts of the coolant is more thorough, avoiding the situation of excessively high or low local temperature of the coolant, and making the temperature distribution of the coolant more uniform.

[0025] Furthermore, one end of the plug socket 17 is threadedly connected to a fastening ring 5, the outer side of the plug socket 17 is provided with a threaded protrusion 8, the inside of the fastening ring 5 is provided with a threaded groove 7, the fastening ring 5 is threadedly connected to the plug socket 17 and the fixed seat 16, one end of the fixed seat 16 is provided with a limiting ring 3, and one side of the limiting ring 3 is provided with a fastening washer 4.

[0026] In a further embodiment provided by this utility model, the fastening ring 5, after connecting the water pipe 6 to the connecting pipe 2, is used to thread the fixing seat 16 and the plug seat 17 together with the threaded groove 7 inside the fastening ring 5, and the threaded protrusions 8 on the outer sides of both the fixing seat 16 and the plug seat 17. This threaded connection eliminates the need for complex tools; simply rotating the ring allows for connection or disassembly of the components. This simplifies maintenance and component replacement, reducing repair time. The limiting ring 3 and fastening washer 4 at one end of the fixing seat 16 restrict the movement of the fastening ring 5, preventing it from moving beyond the fastening washer 4. This increases friction and prevents loosening during use, improving the overall structural stability of the radiator 1, avoiding damage to components due to uneven stress, and extending its service life.

[0027] In this utility model, the fixing seat 16 connected to one side of the connecting pipe 2 is first aligned with the plug seat 17. Due to the rubber ring 11 and the spring 18 inside the rubber ring 11 provided in the water pipe 6, the spring 18 provides elastic support to make the rubber ring 11 more flexible. When the water pipe 6 is connected to the connecting pipe 2, the rubber ring 11 can tightly fit the inner wall of the water pipe 6 against the inner wall of the connecting pipe 2, effectively preventing coolant leakage. Between the fixing seat 16 and the plug seat 17, the sealing groove 15 fits into the sealing protrusion 9, and the sealing protrusion 9 pushes the sealing rubber ring 10 into the interior of the sealing groove 15, forming another sealing barrier to prevent the coolant of the radiator 1 from seeping out from the connection, greatly reducing the risk of coolant leakage and ensuring normal coolant circulation. The limiting protrusion 14 at one end of the fixing seat 16 cooperates with the limiting groove 13 on one side of the plug seat 17. When the limiting protrusion 14 fits into the limiting groove 13, the installation can be quickly and accurately aligned, reducing the difficulty of installation, reducing installation time and labor costs. The guide groove 12 inside the connecting pipe 2 allows the coolant to be guided to form a spiral flow inside the connecting pipe 2. This flow mode is more likely to generate turbulence. In the turbulent state, the mixing between the various parts of the coolant is more thorough, avoiding the situation of excessively high or low local temperature of the coolant, and making the temperature distribution of the coolant more uniform.

[0028] The foregoing has only described certain exemplary embodiments of this utility model by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of this utility model. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of this utility model.
