Description

Technical Field

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

[0002] In many fields such as electronic equipment and industrial machinery, metal heat sinks are crucial heat dissipation components, and their performance directly affects the operational stability and lifespan of the equipment. Thanks to the excellent thermal conductivity of metal, metal heat sinks can quickly transfer heat generated by the heat source, maintaining the equipment in a suitable temperature environment.

[0003] To meet diverse heat dissipation needs, Chinese Utility Model Patent Publication No. CN222674755U discloses a metal heat sink splicing structure. This structure uses plug-in rods to fix multiple heat sink bodies to corresponding positions on a connector, enabling the combined use of multiple heat sinks. This splicing method increases the flexibility of heat sink body assembly and disassembly to a certain extent.

[0004] However, the existing metal heat sink splicing structure has significant shortcomings. Due to the design limitations of the connector, heat sinks can only be installed according to a pre-set quantity. That is, once the heat sinks are spliced ​​according to the connector specifications, their overall heat dissipation area is fixed. In practical applications, the heat dissipation requirements of different devices in different working scenarios are dynamically changing. If an old device is replaced with a new one, and the heat dissipation area of ​​the new device differs from that of the old device, then the heat sink with a fixed heat dissipation area cannot meet the requirements, thus requiring the purchase of new heat sinks and increasing equipment costs. Utility Model Content

[0005] The main purpose of this utility model is to provide a metal heat sink, which aims to overcome the shortcomings of insufficient flexibility in the splicing structure of existing metal heat sinks, so that the area of ​​the heat sink can be flexibly adjusted according to the actual heat dissipation needs, thereby adapting to the heat dissipation requirements of different equipment in different working scenarios, improving the versatility and practicality of the heat sink, and reducing the cost of use.

[0006] To achieve the above objectives, this utility model proposes a metal heat sink, comprising a first heat sink, a last heat sink, and several middle heat sinks. The bottom of the first heat sink is fixedly connected to a first heat sink plate, the bottom of the last heat sink is fixedly connected to a last heat sink plate, and the bottom of the middle heat sinks is fixedly connected to middle heat sink plates. The middle heat sinks are located between the first and last heat sinks. The several middle heat sink plates are sequentially and detachably connected. The first middle heat sink plate is embedded in the first heat sink plate, and the last heat sink plate is embedded in the last middle heat sink plate.

[0007] In one possible implementation, the front ends of the middle section heat sink and the end section heat sink are provided with connecting protrusions, and the rear ends of the middle section heat sink and the first section heat sink are provided with connecting grooves. The connecting protrusions are embedded in the connecting grooves, and the middle section heat sink is detachably connected to the adjacent middle section heat sink, the first section heat sink, or the end section heat sink through the connecting protrusions and the connecting grooves.

[0008] In one possible implementation, the front end of the first heat sink and the end of the last heat sink are provided with positioning holes, which are used to fix the positions of the first heat sink and the last heat sink.

[0009] In one possible implementation, the first heat sink, the last heat sink, and the middle heat sink are all provided with heat dissipation pipes. The heat dissipation pipes are embedded in their corresponding first heat sink, last heat sink, or middle heat sink, and the heat dissipation pipes extend to their corresponding first heat sink plate, last heat sink plate, or middle heat dissipation pipe.

[0010] In one possible implementation, a stabilizing plate is fixedly connected to the front side of both the middle section heat sink and the end section heat sink, and a stabilizing groove is provided on the rear side of both the middle section heat sink and the first section heat sink, with one end of the stabilizing plate embedded in the stabilizing groove on its front side.

[0011] In one possible implementation, a fixing member is detachably connected between the first heat sink and the last heat sink. The fixing member includes a fixing threaded rod and a fixing nut. Fixing holes are fixedly connected to both sides of the first heat sink and the last heat sink. The fixing threaded rod passes through the fixing holes of the first heat sink and the last heat sink and is threadedly connected to the fixing nut. The fixing member is used to strengthen the connection between the first heat sink and the last heat sink.

[0012] The working principle and beneficial effects of this utility model are as follows:

[0013] This utility model's technical solution utilizes the sequentially detachable connection of the mid-section heat sink, allowing users to flexibly select the appropriate number of mid-section heat sinks based on the required heat dissipation area of ​​the new equipment when replacing devices requiring cooling. For example, when replacing a device with lower cooling requirements with a high-power, high-heat-generating device, the number of mid-section heat sinks can be increased to expand the heat dissipation area and ensure effective heat dissipation of the new device; conversely, if replacing with a device with lower cooling requirements, the number of mid-section heat sinks can be reduced. This flexible adjustment feature greatly improves the applicability of the heat sinks, enabling them to adapt to various devices of different specifications and cooling needs. It also enhances practicality, eliminating the need for users to purchase specific heat sink specifications for different devices. Furthermore, the ability to precisely configure the number of heat sinks according to actual needs avoids unnecessary waste, thereby reducing operating costs. In this way, the lack of flexibility in existing splicing structures is successfully overcome, providing a more cost-effective heat dissipation solution for various devices.

[0021] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0023] like Figures 1-5 As shown, this embodiment proposes a metal heat sink, including a first heat sink 1, a last heat sink 2, and several middle heat sinks 3. The bottom of the first heat sink 1 is fixedly connected to a first heat sink plate 11, the bottom of the last heat sink 2 is fixedly connected to a last heat sink plate 21, and the bottom of the middle heat sink 3 is fixedly connected to a middle heat sink plate 31. The middle heat sink 3 is located between the first heat sink 1 and the last heat sink 2. The several middle heat sink plates 31 are sequentially and detachably connected. The first middle heat sink plate 31 is embedded in the first heat sink plate 11, and the last heat sink plate 21 is embedded in the last middle heat sink plate 31.

[0024] The first heat sink 1 is used to dissipate heat, transferring it to the surrounding environment through thermal radiation and convection via its structure and surface area. The first heat sink plate 11 serves to connect the equipment requiring heat dissipation and support the first heat sink 1. It is also the initial connecting component of the entire heat sink structure, providing a foundation for the subsequent installation of the middle heat sink plate 31. The presence of the first heat sink 1 increases the overall heat dissipation area and improves heat dissipation efficiency. The fixed connection method of the first heat sink plate 11 ensures the stability of the first heat sink 1, making the entire heat dissipation structure more robust.

[0025] The final heat sink 2 also serves a heat dissipation function, further expanding the heat dissipation area and enhancing the heat dissipation effect. The final heat sink 21 is the final connecting component of the entire heat sink structure, cooperating with the middle heat sink 31 to complete the assembly of the entire heat dissipation structure. Simultaneously, the final heat sink 21 is also used to connect with the equipment requiring heat dissipation, transferring heat from the equipment and securing itself to the equipment. The placement of the final heat sink 2 allows the entire heat sink structure to connect more stably to the equipment. Furthermore, it strengthens the connection between the middle heat sink 3 and the first heat sink 1 within the entire heat sink structure.

[0026] The middle heat sink 3 is the main component for increasing the heat dissipation area, and the arrangement of multiple middle heat sinks 3 can be flexibly adjusted to meet actual needs in terms of heat dissipation capacity. The middle heat sink plate 31 serves to connect the middle heat sinks 3 and allows for detachable connections between them, enabling the adjustment of the number of heat sinks. By increasing or decreasing the number of middle heat sinks 3, the heat dissipation area can be flexibly adjusted to meet the heat dissipation requirements of different devices in different working scenarios. The detachable connection design makes installation and disassembly more convenient, facilitating maintenance and replacement.

[0027] In this embodiment, the front ends of the middle section heat sink 31 and the end section heat sink 21 are provided with connecting protrusions 23, and the rear ends of the middle section heat sink 31 and the first section heat sink 11 are provided with connecting grooves 13. The connecting protrusions 23 are embedded in the connecting grooves 13. The middle section heat sink 31 is detachably connected to the adjacent middle section heat sink 31, first section heat sink 11, or end section heat sink 21 through the connecting protrusions 23 and connecting grooves 13. The front sides of the middle section heat sink 3 and the end section heat sink 2 are fixedly connected with stabilizing plates 24, and the rear sides of the middle section heat sink 3 and the first section heat sink 1 are provided with stabilizing grooves 14. One end of the stabilizing plate 24 is embedded in the stabilizing groove 14 on its front side.

[0028] The connecting protrusion 23 is located at the front end of the middle section heat sink 31 and the rear section heat sink 21. Its function is to serve as a key component for connection, inserting into the connecting groove 13 of adjacent heat sinks to achieve a physical connection between the heat sinks. The connecting groove 13 is located at the rear end of the middle section heat sink 31 and the first section heat sink 11. Its function is to receive the connecting protrusion 23, providing a stable embedding space for it, thereby tightly connecting the different heat sinks together. This connection method enables a detachable connection between the heat sinks, allowing users to easily increase or decrease the number of middle section heat sinks 3 according to actual needs. The connecting protrusion 23, embedded in the connecting groove 13, provides a relatively stable connection structure, ensuring a tight connection between the heat sinks, reducing the increase in thermal resistance caused by loosening, and ensuring that heat can be effectively transferred from one heat sink to another, improving overall heat dissipation efficiency.

[0029] The stabilizing plate 24 is fixedly connected to the front side of the middle section heat sink 3 and the end section heat sink 2. Its function is to insert into the stabilizing groove 14 of adjacent heat sinks, enhancing the connection stability between the heat sinks. The stabilizing groove 14 is located on the rear side of the middle section heat sink 3 and the first section heat sink 1, serving to accommodate the stabilizing plate 24 and providing a space for positioning and support. The stabilizing plate 24, embedded in the stabilizing groove 14, further strengthens the connection between the heat sinks, reducing the shaking and displacement of the heat sinks during use. When the equipment vibrates during operation, this structure can maintain the relative position stability of the heat sinks, preventing the heat dissipation effect from being affected by the shaking of the heat sinks. The stabilizing plate 24 can also increase the contact area between the heat sinks to a certain extent, which helps the heat transfer between different heat sinks, thereby helping to improve the heat dissipation efficiency. At the same time, the cooperation between the stabilizing plate 24 and the stabilizing groove 14 can also guide the airflow between the heat sinks, optimize the heat dissipation channel, and enhance the convective heat dissipation effect.

[0030] In this embodiment, positioning holes 12 are provided at the front end of the first heat sink 11 and the rear end of the last heat sink 21. The positioning holes 12 are used to fix the positions of the first heat sink 11 and the last heat sink 21. A fixing component is detachably connected between the first heat sink 1 and the last heat sink 2. The fixing component includes a fixing threaded rod 5 and a fixing nut 6. Fixing holes 22 are fixedly connected to both sides of the first heat sink 1 and the last heat sink 2. The fixing threaded rod 5 passes through the fixing holes 22 of the first heat sink 1 and the last heat sink 2 and is threadedly connected to the fixing nut 6. The fixing component is used to strengthen the connection between the first heat sink 1 and the last heat sink 2.

[0031] The positioning holes 12 at the front end of the first heat sink 11 and the end of the last heat sink 21, during the heat sink installation process, cooperate with corresponding positioning pins or bolts on the equipment to accurately fix the positions of the first and last heat sink 21. This effectively prevents the heat sink from shifting during installation, ensuring a tight fit between the heat sink and the heat-generating equipment, creating favorable conditions for heat conduction. The positioning holes 12 ensure accurate and consistent installation, reducing the problem of decreased heat dissipation efficiency due to installation position deviations. Simultaneously, precise positioning also makes the subsequent installation of the middle heat sink 3 more convenient, improving the overall heat sink installation efficiency and enhancing the stability of the heat sink in the equipment, reducing the risk of displacement due to vibration and other factors.

[0032] The fasteners tightly connect the first heat sink 1 and the last heat sink 2, enhancing the mechanical stability of the entire heat sink structure. This allows it to withstand certain vibrations and external impacts during equipment operation, preventing loosening or detachment. The fasteners also improve thermal contact between the first and last heat sinks, reducing thermal resistance and promoting rapid heat transfer throughout the heat sink assembly, thus improving heat dissipation efficiency. The fixing holes 22 serve as the through-holes for the threaded rod 5, providing positioning and support for the fasteners. Pre-fixed on both sides of the first and last heat sinks, they ensure accurate and convenient installation. The threaded rod 5 passes through the fixing holes 22 of both heat sinks, providing the main connection structure. The threaded rod initially connects the first and last heat sinks, establishing a stable connection framework. The fixing nut 6 is threaded to the threaded rod 5, generating axial tension on the first and last heat sinks during tightening, bringing them closer together and ensuring a tight fit. This tight fit not only enhances the stability of the mechanical connection but also reduces thermal resistance between the two components, facilitating uniform heat conduction throughout the entire heatsink structure. The fasteners utilize a detachable threaded connection, making it convenient for users to install, replace, or repair the heatsink, thus reducing operating costs and maintenance complexity.

[0033] In this embodiment, the first heat sink 1, the last heat sink 2, and the middle heat sink 3 are all provided with heat pipes 4. The heat pipes 4 are embedded in their corresponding first heat sink 1, last heat sink 2, or middle heat sink 3, and the heat pipes 4 extend to their corresponding first heat sink 11, last heat sink 21, or middle heat pipe 4.

[0034] Heat pipes 4 are embedded in the first heat sink 1, the last heat sink 2, and the middle heat sink 3, extending to the corresponding heat sink plates. This allows for rapid transfer of heat absorbed by the heat sinks to the heat sink plates. Because heat pipes 4 typically have good thermal conductivity, they effectively reduce the thermal resistance between the heat sinks and the heat sink plates, allowing for smoother heat conduction throughout the entire heat dissipation structure. By placing heat pipes 4 in different heat sinks and heat sink plates, heat is evenly distributed across the entire metal heat sink, preventing localized overheating. This is because heat pipes 4 can transfer heat from higher-temperature areas to lower-temperature areas, resulting in a more balanced temperature across the entire heat dissipation structure.
