Description

TECHNICAL FIELD

[0001] The utility model relates to a heat dissipation technical field especially relates to a heat dissipation fin and equipment. BACKGROUND

[0002] Heat dissipation fins play a crucial role in modern electronic devices, as they ensure that sensitive electronic components do not overheat and get damaged. These small but powerful devices are typically installed on central processing units (CPUs), graphics processing units (GPUs), and other high-power electronic components that generate a lot of heat when in operation. The design principle of heat dissipation fins is to increase the surface area in contact with air, thereby improving the efficiency of heat exchange and accelerating the dissipation of heat, ensuring that the device operates stably within a safe temperature range. In personal computers, heat dissipation fins are combined with fans to form an efficient cooling system, helping the computer to remain cool and avoid performance degradation or system crashes caused by overheating. In larger devices such as servers and data centers, heat dissipation fins are equally important, as these devices often need to operate continuously for long periods of time, and heat dissipation fins help maintain the stability and extend the service life of the device. In addition to computers and servers, heat dissipation fins are also widely used in the automotive industry, especially in engines and power systems, to help control temperature and prevent overheating-induced failures. In lighting devices, heat dissipation fins are used in LED bulbs and lamps to ensure that these high-efficiency light sources do not decrease in brightness or be damaged due to excessive temperature during long-term use. In industrial machinery and medical devices, heat dissipation fins are also indispensable, as they ensure the stable operation of the device and improve the reliability and safety of the device. Some small electronic devices usually use copper sheets for heat dissipation, but copper sheets are soft and prone to deformation. Therefore, the connection position on the copper sheet may be offset, making it difficult to directly connect to the electronic device. The existing technology usually uses stainless steel spring sheets to fix and connect with the copper sheet, and sets a connection position on the stainless steel spring sheet to connect with the electronic device. This method not only has higher cost, but also occupies more space. Therefore, there is a need for a heat dissipation fin with lower cost. SUMMARY

[0026] Copper sheet as the effect of the fin is indeed very outstanding. Copper, this metal, is known for its excellent thermal conductivity, it can quickly conduct heat from the heat source to other areas. This feature makes copper sheet an ideal choice for electronic equipment cooling. In computers, power supplies, and even car engines, copper sheets are widely used in heat dissipation systems, helping these devices to maintain a safe operating temperature range. Since the thermal conductivity of copper is about twice that of aluminum, it means that copper sheet can conduct more heat per unit time. Therefore, using copper sheet as a heat dissipation material can effectively reduce the temperature of the device and prolong its service life. In addition, the surface of copper sheet can usually be specially treated, such as nickel plating or silver plating, to further improve its heat dissipation efficiency and corrosion resistance. Although copper sheet has excellent performance in heat dissipation, its density is larger and the weight is relatively heavier, which may become a limiting factor in some applications. At the same time, the cost of copper is higher than that of aluminum, which makes copper sheet may not be the best choice in cost-sensitive projects. However, for those occasions that require extremely high heat dissipation performance, such as high-performance computers or precision instruments, copper sheet is still an irreplaceable material. In these applications, the high-efficiency heat dissipation capacity of copper sheet ensures the stable operation of the device and the reliability of the data, thereby proving its value.

[0027] Copper sheet, as a common metal material, is widely used in various industrial fields due to its unique physical properties. Its relatively soft texture makes it prone to deformation during processing and use. This deformability can be an advantage in certain situations, such as when bending or shaping is required, as copper sheets can easily be shaped into the desired form. However, in applications where precise dimensions and shape are required, the softness of copper sheets can be a challenge. Due to its deformability, copper sheets require special care during transportation and storage to avoid shape changes caused by external forces. In addition, engineers and designers take various measures when using copper sheets, such as adding support structures or choosing appropriate thicknesses, to ensure the stability and reliability of copper sheets in practical applications. When installing copper sheets as heat sinks on equipment, the softness and deformability of copper sheets cause the connecting parts on the copper sheets to shift, making it difficult to accurately install the copper sheets on the equipment. In particular, to more stably install the copper sheets on the equipment, multiple connecting parts are provided for connection and fixation. However, after the copper sheets shift, the connecting parts cannot accurately correspond to the connecting parts on the equipment.

[0028] Referring to Figure 1 , Figure 2 and Figure 3 , the first embodiment of the utility model discloses a heat sink for dissipating heat from equipment, the equipment is provided with a connecting position, comprising: a main body 1, an elastic arm 2 and a connecting part 3, the main body 1 is a copper sheet; the elastic arm 2 is integrally formed with the main body 1, the elastic arm 2 corresponds to the connecting position one by one, the elastic arm 2 is provided in a spiral shape, one end of the outer side of the spiral shape is a first end 4, the first end is fixedly arranged with the main body 1, one end of the inner side of the spiral shape is a second end 5, the second end 5 is movable relative to the first end 4, at least two elastic arms 2 are arranged on the main body 1; the connecting part 3 is arranged at the second end 5, the connecting part 3 corresponds to the connecting position one by one, and the connecting part 3 is used for fixedly connecting with the connecting position. When manufacturing the heat sink, the main body 1, the elastic arm 2 and the connecting part 3 can be integrally punched. The copper sheet has good heat dissipation capacity, is relatively soft and easy to deform, and has poor elastic deformation capacity. Therefore, when using the heat sink, the main body 1 is prone to deformation, thereby changing the positional relationship between the elastic arm 2 and the connecting part 3, so that the connecting part 3 cannot be connected to the connecting position of the equipment one by one. Therefore, the elastic arm 2 is provided in a spiral shape, which improves the elastic deformation capacity of the elastic arm 2 without changing the elastic deformation capacity of the material, so that the elastic arm 2 has greater elastic deformation capacity. In this way, when the positional relationship between the elastic arm 2 and the connecting part 3 changes, the second part moves relative to the first part through the elastic deformation of the elastic arm 2, so that the connecting part 3 on the second end 5 accurately corresponds to the connecting part on the equipment one by one.

[0029] The influence of the spiral arrangement on elastic deformation mainly manifests in the following aspects: firstly, the spiral structure can effectively disperse stress and reduce the influence of concentrated load on the material. This dispersion effect enables the material to distribute stress more uniformly when subjected to external force, thereby improving the elastic deformation capacity of the material. Secondly, the spiral arrangement can increase the flexibility of the material. Since the spiral structure has certain bending and torsional capacity, the material can absorb energy through its own deformation when subjected to external force, thereby avoiding or reducing permanent deformation caused by external force. Thirdly, the geometric characteristics of the spiral structure enable it to have good restoring force within the elastic range. When the external force is removed, the spiral structure can quickly recover to the original state, and this rapid recovery capacity is an important feature of elastic deformation. Finally, the spiral arrangement can also adjust the elastic modulus and stiffness of the material by changing parameters such as the diameter, pitch, and number of turns of the spiral, thereby meeting the requirements of different application scenarios for elastic deformation performance.

[0030] According to some embodiments of the present application, three elastic arms 2 are arranged on the main body 1, the connection point of the connecting part 3 on the first elastic arm 2 and the device is the first connection point, the connection point of the connecting part 3 on the second elastic arm 2 and the device is the second connection point, and the connection point of the connecting part 3 on the third elastic arm 2 and the device is the third connection point. The first, second, and third connection points are not on the same straight line. The heat dissipation fin can be more stably arranged on the device, three elastic arms 2 and three connecting parts 3 are arranged on the main body 1, so that the heat dissipation fin has three connection points with the device. Thus, the connection between the heat dissipation fin and the device is more stable. In the installation of the heat dissipation fin, in order to facilitate the disassembly and replacement of the heat dissipation fin, the connecting part 3 is usually connected to the connecting position by screwing. Only a threaded hole needs to be arranged on the connecting position, and the connecting part 3 can be connected accurately and conveniently. When one elastic arm 2 is arranged, only one corresponding connecting part 3 and connecting position are provided. At this time, when the heat dissipation fin is fixed on the device, the heat dissipation fin is easily rotated around the connecting position, thereby causing the heat dissipation fin to deviate and fail. When two elastic arms 2 are arranged, only two corresponding connecting parts 3 and connecting positions are provided. At this time, when the heat dissipation fin is fixed on the device, there are two connection points, which limit the heat dissipation fin from rotating around the connecting position. However, only two connecting parts 3 make the relatively soft main body 1 prone to warping, which causes the main body 1 to move away from the device, thereby making the heat dissipation effect of the heat dissipation fin unable to be fully exerted. Therefore, the arrangement of three elastic arms enables the heat dissipation fin to be stably and firmly attached to the device.

[0031] According to some embodiments of the utility model, the distance between any two of the first connecting point, the second connecting point and the third connecting point is equal. Under this condition, the first connecting point, the second connecting point and the third connecting point serve as three vertices of an equilateral triangle, so that the fixing of the heat dissipation fin is more stable, and the stress structure of the heat dissipation fin during fixing is also improved.

[0032] According to some embodiments of the utility model, the elastic arm 2 is spirally arranged by copper strips to form a spiral shape, the width of the copper strip is not less than 2mm, the interval of the spirally arranged copper strips is not less than 1mm and not more than 2mm. If the width of the copper strip is too small, the elastic arm 2 cannot provide sufficient fixing force, so that the connection of the elastic arm 2 fails. If the interval of the spirally arranged copper strips is too large, not only sufficient fixing force cannot be provided, but also more space is occupied, so the width of the copper strip is set to be not less than 2mm. If the interval of the spirally arranged copper strips is too small, sufficient elastic deformation cannot be provided, so the interval of the spirally arranged copper strips is set to be between 1mm and 2mm.

[0033] According to some embodiments of the utility model, the thickness of the main body 1 is equal to the thickness of the elastic arm 2. When the thickness of the main body 1 is equal to the thickness of the elastic arm 2, integrated processing is easier. A die can be used to punch out the main body, the elastic arm 2 and the connecting part 3 from a copper sheet at one time.

[0034] According to some embodiments of the utility model, the connecting length between the first end 4 and the main body 1 is not less than 4mm. The connection between the elastic arm 2 and the main body 1 is more stable.

[0035] According to some embodiments of the utility model, the number of spiral layers of the elastic arm 2 is not less than two. In order to ensure that the elastic arm 2 has sufficient elastic deformation capacity, the number of spiral layers of the elastic arm 2 is set to be not less than two.

[0036] There is a complex interaction between the elasticity of a helical structure and the number of its spiral layers. In many cases, this unique geometry can exhibit increasingly stronger elastic properties as the number of spiral layers gradually increases. This is because each layer of the spiral provides additional tensile and compressive resistance to the overall structure, allowing the entire helix to better distribute and absorb energy when subjected to external forces. However, this relationship is not simply linear. In fact, when the number of spiral layers reaches a certain point, continuing to increase the number of layers may gradually reduce the contribution to elasticity, and in some cases, too many spiral layers can make the structure too rigid, thereby reducing its overall elasticity. Therefore, finding a balance point of the number of spiral layers is crucial for designing a helical structure that is both sufficiently elastic and maintains moderate flexibility. In addition to the number of spiral layers, the elasticity of a helix is also influenced by various factors. For example, the choice of material plays a decisive role in the elasticity of the helix. Different materials have different elastic moduli and fatigue resistance, which directly affect the elasticity and durability of the helical structure. In addition, the helix pitch and helix angle are also important factors affecting the elasticity of the helix. Structures with closer helix pitches tend to have better compression resistance, while the size of the helix angle determines the degree of deformation of the structure when stretched. Therefore, when designing a helical structure, these factors must be considered comprehensively to ensure that the final product meets the needs of specific applications.

[0037] The helix pitch in a helical structure refers to the distance between adjacent two helix lines in the helical structure. This parameter has an important influence on the performance and function of the helical structure. In different application fields such as architecture, mechanical design, etc., the size of the helix pitch will be adjusted according to specific needs. The influence of the helix pitch between helix lines in a helical structure on elastic deformation mainly reflects in the following aspects: first, the size of the helix pitch between helix lines directly affects the stiffness of the structure. When the helix pitch is small, the interaction between the helix lines is enhanced, the overall stiffness of the structure is large, and the resistance to deformation is strong. On the contrary, when the helix pitch between the helix lines increases, the stiffness of the structure will decrease, and the elastic deformation of the structure will be easier. Second, the size of the pitch also affects the stress distribution of the structure. Smaller pitch means larger contact area between helix lines, more uniform stress distribution, thereby reducing stress concentration and improving the load-bearing capacity of the structure. Larger pitch may lead to stress concentration and reduce the elastic deformation capacity of the structure.

[0038] According to some embodiments of the present application, a through hole is formed in the connecting portion 3, the through hole is used for connecting the equipment, the diameter of the through hole is not less than 1mm, and the distance between the through hole and the edge of the connecting portion 3 is not less than 2mm. Thus, the structural strength of the fixed connection between the elastic arm 2 and the equipment is ensured.

[0040] The utility model has been described in detail above in combination with the drawings, but the utility model is not limited to the above embodiments, and various changes can be made within the knowledge range possessed by those skilled in the art without departing from the purpose of the utility model.
