Description

Technical Field

[0001] This utility model relates to the field of radiator manufacturing technology, and more specifically, to a magnetically attached cold-forged radiator. Background Technology

[0002] Cold forging is a general term for plastic forming processes such as cold die forging, cold extrusion, and cold heading. It is a forming process performed below the recrystallization temperature of the material, specifically below the recovery temperature. It is a near-net-shape forming process, producing parts with high strength, precision, and good surface quality. Its thermal conductivity is generally around 226 W / mK.

[0003] Cold forging, a precision forming technology, can produce complex-shaped forgings in a single process, resulting in better shape stability and integrity of the radiator. However, cold forging requires a certain level of precision in the mold; lower precision leads to more defects in the cold-forged material and can even result in forging failure, such as insufficient strength. This is particularly problematic for radiators requiring precision cold forging, increasing costs and hindering the development of the cold forging process. Therefore, we propose a magnetically attached cold-forged radiator. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a magnetic docking type cold forging heat sink to solve the technical problem that the current cold forging precision heat sink has high requirements for molds.

[0005] To solve the above technical problems, this utility model provides the following technical solution: a magnetic attraction docking type cold forging heat sink, including a sleeve, a heat dissipation structure is installed inside the sleeve, the heat dissipation structure includes a plurality of embedded plates and heat conducting plates, a positioning rod is connected between the plurality of heat dissipation structures, and a magnetic docking device is connected between two adjacent heat dissipation structures;

[0006] The magnetic connector consists of a nested ring, a thermally conductive magnetic plate, and an embedded magnetic plate. Several thermally conductive magnetic plates are evenly installed on the nested ring. The end of the thermally conductive magnetic plate away from the nested ring is connected and fixed to the embedded magnetic plate. Vertical grooves are opened on the thermally conductive magnetic plate.

[0007] The heat dissipation structure is sleeved with the positioning rod, the heat conduction plate is connected and fixed to the embedded plate, and the ends of several heat conduction plates away from the embedded plate are connected to a connecting ring of the same specification as the nesting ring.

[0008] Preferably, a heat dissipation structure consisting of several embedded plates and heat-conducting plates is uniformly installed on the connecting ring, and the inner wall of the connecting ring is sleeved with the positioning rod.

[0009] Preferably, the heat-conducting magnetic plate is detachably connected with a positioning buckle, and the heat-conducting plate has a positioning groove corresponding to the positioning buckle. Each heat-conducting magnetic plate has a fan-shaped structure.

[0010] Preferably, a limiting plate is installed between the positioning rod and the heat-conducting plate on the outer heat dissipation structure, and an outer sealing plate is also connected above the positioning rod on the limiting plate.

[0011] Preferably, the sleeve has multiple heat dissipation grooves for heat dissipation, and the inner wall of the sleeve has an embedding groove for connecting and fixing with the embedding plate and the embedding magnetic plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model designs a magnetic connector structure, which achieves seamless connection between two adjacent heat dissipation structures through magnetic docking. Compared with direct cold forging, it has lower cost and lower precision requirements. It adopts a modular design, and after cold forging, each component can be embedded and magnetically connected for installation, solving the problem of excessively high mold precision requirements in the prior art of cold forging. At the same time, the heat-conducting magnetic suction plate and the embedded magnetic suction plate in the magnetic connector adopt a decentralized structure, and each adopts a fan-shaped structure to increase the overall heat dissipation area. In addition, vertical grooves are opened on the inner wall of the heat-conducting magnetic suction plate, so that the heat-conducting plate at the bottom of the vertical groove directly contacts the air, which facilitates the subsequent heat dissipation of the cavity.

[0014] 2. This utility model also designs a heat dissipation structure. Through the heat conduction plate and the embedded plate in the heat dissipation structure, heat is conducted and output to the embedded plate and then dissipated through the sleeve. Uniform heat dissipation is achieved through the heat dissipation fins composed of multiple heat conduction plates. Attached Figure Description

Detailed Implementation

[0022] like Figures 1 to 5 As shown, the present invention relates to a magnetic docking type cold forging heat sink, including a sleeve 100, a heat dissipation structure is installed inside the sleeve 100, the heat dissipation structure includes a plurality of embedded plates 240 and heat conducting plates 230, a positioning rod 200 is connected between the plurality of heat dissipation structures, and a magnetic docking device is connected between two adjacent heat dissipation structures.

[0023] The magnetic connector consists of a nested ring 300, a thermally conductive magnetic plate 310, and an embedded magnetic plate 320. Several thermally conductive magnetic plates 310 are evenly installed on the nested ring 300. The end of the thermally conductive magnetic plate 310 away from the nested ring 300 is connected and fixed to the embedded magnetic plate 320. The thermally conductive magnetic plate 310 has a vertical groove 340. The entire structure of the magnetic connector is made of magnetic metal, which has a certain strength and high magnetism. It is installed between two heat dissipation structures, thereby realizing modular docking installation while reducing the dependence on high-precision cold-pressing molds and reducing the generation of defective products. At the same time, the thermal conductivity of the metal structure is not affected.

[0024] The heat dissipation structure is sleeved with the positioning rod 200. The heat-conducting plate 230 is connected and fixed to the embedded plate 240. A connecting ring of the same specification as the nested ring 300 is connected to one end of each heat-conducting plate 230 away from the embedded plate 240. The connecting ring connects the heat-conducting plate 230, and the heat-conducting plate 230 connects to the embedded plate 240, forming an integrated heat dissipation structure. Several heat-conducting plates 230 form heat dissipation fins, which can be used in conjunction with an external cooling fan to achieve active heat dissipation.

[0025] This invention utilizes a magnetic connector structure to achieve seamless connection between two adjacent heat dissipation structures through magnetic docking. Compared to direct cold forging, this method is lower in cost and requires less precision. It employs a modular design, allowing for easy embedding and magnetic docking of individual components after cold forging. This solves the problem of excessively high mold precision requirements in existing cold forging techniques.

[0026] This utility model also designs a heat dissipation structure. Through the heat conduction plate 230 and the embedded plate 240 in the heat dissipation structure, the heat is conducted and output to the embedded plate 240 and then dissipated through the sleeve 100. Uniform heat dissipation is achieved through the heat dissipation fins composed of multiple heat conduction plates 230.

[0027] Specifically, a heat dissipation structure composed of several embedded plates 240 and heat-conducting plates 230 is evenly installed on the connecting ring, and the inner wall of the connecting ring is sleeved with the positioning rod 200. During installation, the connecting ring is sleeved on the positioning rod 200, so that the entire heat dissipation structure is sleeved on the positioning rod 200, and finally the magnetic docking installation operation of the heat sink is realized.

[0028] Furthermore, a positioning buckle 330 is detachably connected to the heat-conducting magnetic plate 310. The heat-conducting plate 230 has a positioning groove corresponding to the positioning buckle 330, and each heat-conducting magnetic plate 310 has a fan-shaped structure. The positioning buckle 330 directly engages with the positioning groove, achieving both magnetic attraction and fixation, thereby improving the connection strength between the two heat dissipation structures.

[0029] It is worth noting that a limiting plate 220 is installed between the positioning rod 200 and the heat-conducting plate 230 on the outer heat dissipation structure. An outer sealing plate 210 is also connected above the positioning rod 200 above the limiting plate 220. The outer sealing plate 210 has an overall annular structure, and its bottom is toothed to fit between the multiple heat-conducting plates 230, reducing the occurrence of deformation of the heat-conducting plates 230 and achieving overall encapsulation.

[0030] It is worth mentioning that the sleeve 100 has multiple heat dissipation grooves 110 for heat dissipation, and the inner wall of the sleeve 100 has embedding grooves 120 for connecting and fixing with the embedding plate 240 and the embedding magnetic plate 320. The heat dissipation grooves 110 effectively increase the heat dissipation area and improve heat dissipation performance. At the same time, the embedding grooves 120 realize the embedding and fixing of the internal heat dissipation structure, improving the overall integrity. The sleeve 100, the heat dissipation structure, and the magnetic connector are all separate structures, produced by cold forging. The structure itself is simple and does not require the use of high-precision components. After cold forging, the heat dissipation structure is connected and fixed by the magnetic connector, achieving high performance while reducing the dependence on high-precision cold forging dies.

[0031] Working Principle: This embodiment provides a magnetically attached cold-forged radiator. During production, the sleeve 100 and the heat dissipation structure are cold-forged separately. After cold forging, they are assembled with the positioning rod 200. First, the outer sealing plate 210 is installed on the positioning rod 200, and then the limiting plate 220 is installed. Next, the first heat dissipation structure is installed, with its heat-conducting plate 230 inserted into the teeth of the limiting plate 220. Then, the magnetic connector is installed, and the heat-conducting magnetic suction plate 310 on the magnetic connector corresponds to the heat-conducting plate 230. The positioning buckle 330 on the heat-conducting magnetic suction plate 310 is pressed against the positioning groove on the heat-conducting plate 230. After embedding, the limiting plate 220 and the outer sealing plate 210 are installed in sequence for sealing. After sealing, the sleeve 100 is placed on the outer wall of the heat dissipation structure, and the embedding groove 120 on the sleeve 100 is inserted into the embedding plate 240, thus realizing the overall radiator installation.

[0032] By creating vertical slots 340 on the thermally conductive magnetic plate 310, an air cavity is formed between the thermally conductive magnetic plate 310 and the heat-conducting plate 230. Since air has a relatively low thermal conductivity and the thermally conductive magnetic plate 310 has lower heat dissipation performance compared to the heat-conducting plate 230, the presence of the air cavity effectively adds a layer of thermal resistance between the two plates. This reduces the heat transfer through direct contact, allowing more heat to dissipate via air convection and radiation, thus improving heat dissipation efficiency. In practical applications, this method can be optimized in conjunction with an external fan.

[0033] 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.
