Description

Technical Field

[0001] This utility model belongs to the field of heat dissipation equipment technology, and in particular relates to a heat sink structure. Background Technology

[0002] In electronic devices, various components generate a large amount of heat during operation. If this heat is not dissipated in time, the components will overheat, affecting their performance and lifespan, and even causing malfunctions. Therefore, heat sinks are an indispensable component in electronic devices, and their performance directly affects the stable operation of the equipment.

[0003] Currently, traditional heatsinks typically consist of heat-absorbing components, heat dissipation fins, and a fan. The fan is mounted on the heat dissipation fins using a fan mount and screws. This installation method has significant drawbacks: when the fan is damaged and needs replacement, the disassembly and assembly process is cumbersome, requiring the use of special tools to remove multiple screws and other fasteners, which is extremely inconvenient, especially in confined installation environments; moreover, since the fan and mount are usually fixedly connected, if the fan is damaged, the entire fan mount often needs to be replaced, which not only increases maintenance costs but also wastes resources. Utility Model Content

[0004] The purpose of this utility model is to provide a heat sink structure, which aims to solve the technical problems of inconvenient disassembly and assembly and high replacement cost of traditional heat sink fans in the prior art.

[0005] To achieve the above objectives, the heat sink structure provided in this embodiment includes a heat absorption plate, with heat dissipation fins for cooling components at the upper end of the heat absorption plate. A fan bracket is provided on the heat dissipation fins, and quick-release components for detaching and assembling with the fan bracket are also provided on the heat dissipation fins. The quick-release components are distributed at the four corners of the surface of the heat dissipation fins. Multiple heat dissipation fins are provided and arranged and connected sequentially.

[0006] A fan is rotatably mounted on the upper end of the fan bracket, and the fan can rotate on the heat sink fins via the fan bracket. When the heat sink fins dissipate the heat emitted by the components, the fan can diffuse the heat emitted by the heat sink fins into the surrounding air. Through the disassembly and assembly of the fan bracket and the quick-release assembly, the fan bracket and the fan can be detachably installed on the heat sink fins.

[0007] As an optional solution of this utility model, the quick-release assembly includes a first mounting plate and a second mounting plate. The first mounting plate and the second mounting plate are arranged in parallel and spaced apart, and are both fixed to the heat dissipation fins. A gap is formed between the first mounting plate and the second mounting plate, and the fan bracket is formed with a connecting rod that is fitted into the gap. A first limiting block is formed on one side of the first mounting plate to limit the connecting rod in the gap, and a second limiting block is formed on one side of the second mounting plate that is opposite to the first limiting block and limits the connecting rod in the gap. The first limiting block and the second limiting block are laterally staggered on both sides of the gap, and both the first limiting block and the second limiting block are made of plastic.

[0008] As an optional solution of this utility model, a heat pipe is provided between the heat absorption plate and the heat dissipation fins, with one end of the heat pipe located at the bottom end of the heat absorption plate and the other end of the heat pipe inserted into the heat dissipation fins.

[0009] As an optional solution of this utility model, the heat-absorbing plate is provided with a first limiting groove for fixing one end of the heat pipe, and the first limiting groove is formed at the bottom end of the heat-absorbing plate. The first limiting groove arches upward, and one end of the heat pipe is installed inside the first limiting groove.

[0010] As an optional solution of this utility model, the heat dissipation fins are provided with channels for limiting the installation of the other end of the heat pipe, and the channels are all formed inside the heat dissipation fins, and the other end of the heat pipe is inserted into the channels.

[0011] As an optional solution of this utility model, the bottom surface of the heat absorption plate is provided with brackets on both sides for mounting the heat sink fins and fan onto the components. The brackets are provided with first fixing screws, and the first fixing screws are all vertically located at the four corners of the brackets and the bottom of the brackets are provided with washers horizontally.

[0012] As an optional solution of this utility model, the bottom surface of the heat absorption plate is provided with second limiting grooves on both sides for mounting and fixing the bracket, and the support frame is provided with second fixing screws to fix it together with the heat absorption plate to the bottom surface of the heat dissipation fins. The second fixing screws pass through the second limiting grooves, and the second limiting grooves are formed with through holes for the second fixing screws to pass through.

[0013] The heat sink structure provided in this embodiment of the present invention has at least one of the following technical effects:

[0014] The heatsink structure provided in this application enables quick assembly and disassembly of the fan bracket and heatsink fins by setting quick-release components on the heatsink fins and using connecting rods on the fan bracket. When the fan is damaged, there is no need to remove multiple fixing screws; the fan bracket can be removed along with the fan for replacement simply by using the quick-release components. This operation is simple and quick, improving maintenance efficiency and reducing maintenance difficulty. Since the fan bracket and heatsink fins are detachably connected by the quick-release components, when the fan is damaged, only the fan needs to be replaced, without replacing the fan bracket as well, effectively reducing replacement costs and minimizing resource waste.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the embodiments of this utility model, and should not be construed as limiting the utility model.

[0025] In the description of the embodiments of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the embodiments of this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0027] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0028] In one embodiment of this utility model, such as Figures 1-6 As shown, a heat sink structure is provided, including a heat absorber plate 12. The heat absorber plate 12 is made of aluminum alloy with good thermal conductivity, which can quickly absorb the heat generated by the components. Heat dissipation fins 1 for dissipating heat from the components are provided at the upper end of the heat absorber plate 12. Multiple heat dissipation fins 1 are also made of aluminum alloy and are arranged sequentially and connected together by welding to form an integrated heat dissipation structure, increasing the heat dissipation area.

[0029] A fan bracket 6 is mounted on the heat sink 1. The fan bracket 6 is made of engineering plastic, which has a certain strength and toughness. The heat sink 1 is also equipped with quick-release components that can be assembled and disassembled with the fan bracket 6. The quick-release components are distributed at the four corners of the surface of the heat sink 1 to ensure the stability of the fan bracket 6 during installation.

[0030] The quick-release assembly includes a first mounting plate 8 and a second mounting plate 9, both made of stainless steel. They are welded to the heatsink fins 1 and are arranged parallel to each other with a gap between them. The width of this gap is slightly larger than the diameter of the connecting rod on the fan bracket 6. The fan bracket 6 has a connecting rod that is fitted into the gap; the connecting rod is integrally formed with the fan bracket 6.

[0031] A first limiting block 10 is formed on one side of the first mounting plate 8 to confine the connecting rod within the gap. A second limiting block 11 is formed on one side of the second mounting plate 9, opposite to the first limiting block 10 and also confining the connecting rod within the gap. The first limiting block 10 and the second limiting block 11 are laterally staggered on both sides of the gap and are both made of plastic, possessing a certain degree of elasticity. When the connecting rod is inserted into the gap, the first limiting block 10 and the second limiting block 11, under elastic action, limit the connecting rod, preventing it from coming out of the gap. When disassembly is required, simply apply a certain force to push the fan frame 6, causing the connecting rod to deform by pressing against the first limiting block 10 and the second limiting block 11, thus allowing the connecting rod to be removed from the gap, achieving quick assembly and disassembly.

[0032] A fan 2 is mounted on the upper end of the fan bracket 6 via a rotating shaft. The fan 2 can rotate on the heat dissipation fins 1 via the fan bracket 6, with a rotation angle range of 0-90 degrees, so as to adjust the airflow direction according to the actual heat dissipation needs, so that the heat dissipated by the heat dissipation fins 1 can be more effectively diffused into the surrounding air.

[0033] A heat pipe 3 is disposed between the heat absorber plate 12 and the heat dissipation fins 1. The heat pipe 3 is made of copper and filled with a thermally conductive medium, resulting in extremely high thermal conductivity. One end of the heat pipe 3 is located at the bottom end of the heat absorber plate 12. The heat absorber plate 12 is provided with a first limiting groove 14 for fixing one end of the heat pipe 3. The first limiting groove 14 is formed at the bottom end of the heat absorber plate 12 and arches upward. One end of the heat pipe 3 is installed inside the first limiting groove 14 and fixed with thermally conductive silicone to ensure good heat conduction.

[0034] The other end of the heat pipe 3 is inserted into the heat dissipation fin 1. The heat dissipation fin 1 is provided with a channel 7 for limiting the installation of the other end of the heat pipe 3. The channel 7 is formed inside the heat dissipation fin 1. The other end of the heat pipe 3 is inserted into the channel 7 and fixed by welding, so that the heat absorbed by the heat absorption plate 12 can be quickly conducted to the heat dissipation fin 1 through the heat pipe 3.

[0035] On both sides of the bottom surface of the heat absorber plate 12, there are brackets 4 for mounting the heat sink fins 1 and fan 2 onto the components. The brackets 4 are made of stainless steel and have high strength. Each bracket 4 is equipped with a first fixing screw 5, which is vertically located at the four corners of the bracket 4 to fix the bracket 4 to the components. Each bracket 4 has a horizontally placed washer 13 at its bottom end. The washer 13 is made of rubber, which increases friction, improves installation stability, and prevents damage to the surface of the components when the first fixing screws 5 are tightened.

[0036] The bottom surface of the heat absorber plate 12 is provided with second limiting grooves 16 on both sides for mounting and fixing the bracket 4. The bracket 4 is provided with second fixing screws 15 to fix it together with the heat absorber plate 12 to the bottom surface of the heat dissipation fin 1. The second fixing screws 15 pass through the second limiting grooves 16, and the second limiting grooves 16 are formed with through holes 17 for the second fixing screws 15 to pass through. The bracket 4 and the heat absorber plate 12 are fixedly connected by the second fixing screws 15, which facilitates the disassembly and replacement of the bracket 4.

[0037] The working principle of this invention is as follows: In use, the entire heat sink structure is fixedly installed on the component requiring heat dissipation using the first fixing screw 5 on the bracket 4. The heat-absorbing plate 12 is in close contact with the surface of the component, quickly absorbing the heat generated by the component. The heat absorbed by the heat-absorbing plate 12 is conducted to multiple heat dissipation fins 1 through the heat pipe 3, and the heat dissipation fins 1 dissipate the heat into the surrounding air. At the same time, the fan 2 operates, accelerating the diffusion of the heat dissipated by the heat dissipation fins 1, improving heat dissipation efficiency. When it is necessary to adjust the airflow direction of the fan 2, simply rotate the fan 2.

[0038] When fan 2 is damaged and needs to be replaced, simply hold fan bracket 6 and apply a certain force outwards to deform the connecting rod by pressing against the first limiting block 10 and the second limiting block 11. This allows the connecting rod to be removed from the gap, thus removing fan bracket 6 along with fan 2. After replacing the fan 2, align the connecting rod on fan bracket 6 with the gap and apply a certain force to insert it. Under the limiting action of the first limiting block 10 and the second limiting block 11, fan bracket 6 is securely installed on the heat sink fins 1, completing the replacement of fan 2.

[0039] The heat sink structure provided in this application enables quick assembly and disassembly of the fan bracket 6 and the heat sink 1 by setting a quick-release component on the heat sink fin 1 and cooperating with the connecting rod on the fan bracket 6. When the fan 2 is damaged, there is no need to remove multiple fixing screws. The fan bracket 6 can be removed together with the fan 2 for replacement simply by using the quick-release component. The operation is simple and quick, improving maintenance efficiency and reducing maintenance difficulty. Since the fan bracket 6 and the heat sink 1 are detachably connected by the quick-release component, when the fan 2 is damaged, only the fan 2 needs to be replaced, without replacing the fan bracket 6 together, which effectively reduces replacement costs and reduces resource waste.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
