Description

Technical Field

[0001] This utility model relates to the field of radiator technology, and more specifically, to a cold-forged radiator with a rubber-coated structure. Background Technology

[0002] Cold-forged radiators are heat dissipation devices manufactured using the cold forging process. This process applies pressure to a metal billet at room temperature, causing plastic deformation, which makes the material structure denser, increases strength and hardness, and thus gives the radiator excellent heat dissipation performance. They typically use materials with good thermal conductivity, such as aluminum or aluminum alloys, and through cold forging, complex and dense heat dissipation fin structures can be formed, significantly increasing the heat dissipation area. Compared to radiators manufactured using traditional casting or machining processes, cold-forged radiators have higher heat dissipation efficiency, are lighter, have a more robust structure, and are better suited for compact installation spaces. They are widely used in electronic equipment, automotive parts, and other fields. In scenarios such as computer CPU cooling and new energy vehicle battery cooling, they ensure stable equipment operation through efficient heat dissipation, making them a preferred heat dissipation solution that balances heat dissipation performance and structural strength.

[0003] In the application of cold-forged radiators, the fixation and installation of the rubber-coated structure has always been a critical step. In traditional cold-forged radiator designs, the connection between the rubber coating and the radiator mostly relies on external clips or adhesives. During use, vibrations can easily cause loosening and detachment, affecting heat dissipation stability. This requires specialized tools and is difficult to adapt to high-efficiency mass production scenarios. Therefore, we propose a cold-forged radiator with a rubber-coated structure. Utility Model Content

[0018] like Figures 1 to 3As shown, the present invention relates to a cold-forged radiator with a rubber-coated structure, including a heat sink 1, a flow groove 3 and a filling component 4 disposed on the heat sink 1, and fins 2 disposed on the top of the heat sink 1; the filling component 4 includes a filling groove 401 opened inside the heat sink 1, and an inner annular groove 402 is opened inside the heat sink 1, and the inner annular groove 402 is connected to the filling groove 401.

[0019] This utility model, by setting a filling groove 401 structure, allows the adhesive to pass through the first storage groove 4011, the outer annular groove 4012 and the second storage groove 4013, and finally reach the inner annular groove 402, forming a complete and tight filling structure. This effectively avoids the problem of the adhesive easily loosening and falling off in traditional snap-fit ​​or adhesive methods, improves the stability and firmness of the connection between the adhesive and the heat sink 1, and ensures the stability of the heat dissipation process.

[0020] In embodiments of this utility model, such as Figure 1 , Figure 2 , Figure 3 As shown, two sets of fins 2 are fixedly connected to the top of the heat sink 1. One set of fins 2 is located at the surface edge of the heat sink 1, and the other set of fins 2 is located at the center of the heat sink 1. Several flow grooves 3 are formed inside the edge of the heat sink 1, and the flow grooves 3 are connected to the filling groove 401. By setting the fins 2, the gaps between the fins 2 form regular airflow channels. When air flows, the fins 2 can guide the airflow to flow more evenly across the surface of the heat sink 1, avoiding local air stagnation. By setting the flow grooves 3, the air is guided to flow evenly, reducing resistance and enhancing edge heat exchange, thereby improving the overall heat dissipation efficiency and stability of the heat sink 1.

[0021] In embodiments of this utility model, such as Figure 2 , Figure 3 As shown, the filling groove 401 consists of a first storage groove 4011, an outer annular groove 4012, and a second storage groove 4013. The filling groove 401 is annular in the middle with continuous bends at both ends. When it is necessary to place the coating, the worker can first place the coating into the filling groove 401 for storage. Since the filling groove 401 is composed of the first storage groove 4011, the outer annular groove 4012, and the second storage groove 4013, it can effectively and evenly fill the filling groove 401. Furthermore, the filling groove 401 is annular in the middle with continuous bends at both ends, which allows the coating to be stored in the filling groove 401.

[0022] In embodiments of this utility model, such as Figure 2 , Figure 3As shown, the first storage tank 4011 is continuously bent. One end of the first storage tank 4011 is connected to the flow tank 3, and the other end of the first storage tank 4011 is fixedly connected to the outer annular groove 4012. When the coating enters the first storage tank 4011, because the first storage tank 4011 is continuously bent, the coating is stored in the first storage tank 4011. When the coating enters the outer annular groove 4012 along the trajectory of the first storage tank 4011, it is easy to remove the coating through the outer annular groove 4012.

[0023] In embodiments of this utility model, such as Figure 2 , Figure 3 As shown, the outer annular groove 4012 is arranged in a ring shape and is located between the two sets of fins 2. Several second storage grooves 4013 are fixedly connected to the other side of the outer annular groove 4012. The outer annular groove 4012 facilitates the removal of the coated material.

[0024] In embodiments of this utility model, such as Figure 2 , Figure 3 As shown, a plurality of second storage slots 4013 are arranged in a ring array inside the heat sink 1. The shape of the plurality of second storage slots 4013 is continuously bent, and the other end of the plurality of second storage slots 4013 is fixedly connected to the inside of the inner annular groove 402. By setting the second storage slots 4013, it is convenient to store the coating in the second storage slots 4013, avoiding the coating from falling off due to vibration of the heat sink 1 during use. The inner annular groove 402 facilitates the storage of the coating.

[0025] Working Principle: This embodiment provides a cold-forged heat sink with a rubber-coated structure. In use, the rubber material is first introduced from the flow channel 3 through a rubber-coating injection process. The rubber material enters the filling groove 401 of the filling component 4 along the channel of the flow channel 3. Since the flow channel 3 is connected to the first storage groove 4011, the rubber material first flows into the first storage groove 4011, which is continuously bent. Its bent structure facilitates initial path guidance and filling, ensuring that the rubber material is evenly distributed in the edge area of ​​the heat sink 1. Subsequently, the rubber material enters the outer annular groove 4012 from the first storage groove 4011. The outer annular groove 4012 is annular and located between the two sets of fins 2. This design allows the rubber material to form an annular wrapping structure here, enhancing the connection between the middle and the edge of the heat sink 1. The seal is excellent, and the pressure of the adhesive is evenly distributed through a ring-shaped pattern. Next, the adhesive flows from the outer annular groove 4012 to several second storage grooves 4013 arranged in a ring array. The second storage grooves 4013 also adopt a continuous bending design, which further extends the filling path of the adhesive, allowing the adhesive to penetrate deep into the central area of ​​the heat sink 1. Finally, it flows into the inner annular groove 402 through the end of the second storage groove 4013, completing the adhesive filling of the entire filling component 4 and forming a complete encapsulation structure. During the heat dissipation process, the two sets of fins 2 act on the edge and central area of ​​the heat sink 1, respectively. The fins 2 at the edge, together with the airflow guided by the flow groove 3, quickly remove the heat from the edge of the heat sink 1. The fins 2 in the center dissipate heat for the core heat-generating area. The encapsulated structure after filling not only avoids the problem of easy loosening and falling off by the interlocking of the filling groove 401 and the inner annular groove 402, thus ensuring the overall structural stability of the radiator, but also reduces the damage to the connection between the fins 2 and the heat sink 1 caused by vibration by utilizing the insulating and buffering properties of the adhesive. At the same time, it does not affect the heat conduction path between the heat sink 1 and the fins 2, thus achieving the synergistic effect of encapsulation fixation and efficient heat dissipation.

[0026] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
