Description

Technical Field

[0001] This utility model belongs to the field of heat sink technology, and particularly relates to a splicing and locking structure for a split heat sink. Background Technology

[0002] A heatsink is a disc-shaped component made of metal or other thermally conductive materials used to help dissipate heat from electronic devices or other heat-generating parts. It is typically mounted on the surface of the heat source, increasing the contact area with the air to more effectively conduct heat away, thereby reducing the device's operating temperature. In use, the fins and heat pipes on the heatsink are usually fixedly connected by welding.

[0003] Chinese patent discloses an expanded heat sink for a radiator (authorization announcement number CN218240847U). The patented technology includes a sealing aluminum cover, a fixed shell, and an inclined plate. Heat-absorbing copper strips are installed at equal intervals on one side of the fixed shell by screws. The sealing aluminum cover is installed at one end of the fixed shell by locking bolts. Heat-absorbing fans with airflow are installed at equal intervals inside the fixed shell by mounting bases. A filter screen is installed on one side of the heat-absorbing fan by screws.

[0004] However, existing technologies have the following problems when used:

[0005] Firstly, the fins and heat pipes on existing heat sinks are usually fixedly connected by welding, which makes it inconvenient to replace the fins when it is necessary to replace one of the multiple stacked fins.

[0006] Secondly, current heat sinks typically dissipate heat through multiple fins, but relying on the fins for natural heat dissipation results in low heat dissipation efficiency. Utility Model Content

[0007] The purpose of this utility model is to address the aforementioned technical problems by providing a splicing and locking structure for a split heat sink, which facilitates the splicing and locking of multiple fins, makes it easy to install and remove the fins, and allows for multi-directional heat dissipation, thereby improving the heat dissipation effect.

[0008] In view of this, the present invention provides a splicing and locking structure for a split heat sink, comprising:

[0009] A heat dissipation base, wherein a positioning rod is installed at the center of the upper end of the heat dissipation base, a heat pipe is installed on the outer wall of the heat dissipation base, an installation plate is installed through the heat pipe, a fin is penetrated through the upper end of the heat pipe, and the positioning rod is detachably inserted through the center of the fin for splicing and locking the fin;

[0010] An arc-shaped plate is installed on the outer wall of the heat dissipation base. An installation plate one is installed on the upper end of the arc-shaped plate. An installation hole is opened at the front end of the installation plate one. An installation plate two is provided on the inner wall of the installation hole. A fan blade is rotatably installed at the rear end of the installation plate two, which is equivalent to multi-angle heat dissipation of the fins.

[0011] Furthermore, the upper end of the mounting plate has a circular hole three, the upper end of the heat pipe passes through the circular hole three, and the outer wall of the heat pipe is fixed to the inner wall of the circular hole three.

[0012] Furthermore, a spring is installed at the lower end of the fin, and a circular hole is opened at the upper end of the fin. The upper end of the heat pipe passes through the circular hole in the vertical direction. The lower end of the spring is attached to the mounting plate. Among the fins that are stacked along the height direction of the heat dissipation base, the lower end of the spring installed at the lower end of the upper fin is attached to the upper end surface of the lower fin.

[0013] Furthermore, the vertical center of the spring is coaxial with the vertical center of the circular hole in the fin.

[0014] Furthermore, a second circular hole is provided at the upper end of the fin, and the upper end of the positioning rod passes through the second circular hole.

[0015] Furthermore, a ring 1 is installed on the upper end of the fin, and a ring hole 1 is opened on the upper end of the ring 1. A bearing is installed in the ring hole 1, and a ring 2 is rotatably connected in the bearing. A ring 2 is opened on the upper end of the ring 2, and a connecting block 2 is installed in the inner cavity of the ring hole 2. A positioning post is fixed on the upper end of the connecting block 2, and a connecting block 1 is fixed on the outer wall of the positioning rod, with the positioning post penetrating the connecting block 1.

[0016] Furthermore, the second connecting block is located below the first connecting block, and the first connecting block has a positioning hole at its upper end, with the top of the positioning post penetrating through the positioning hole.

[0017] Furthermore, a motor is installed at the front end of the second mounting plate, and the motor drive end is connected to the fan blades.

[0018] The beneficial effects of this utility model are:

[0019] When heat dissipation is required for electronic components, the heat sink base fits against the electronic components, a heat pipe passes through a first circular hole, a positioning rod passes through a second circular hole, and the fins are pressed down. The springs deform elastically, and simultaneously, the second ring rotates, causing the second connecting block to move downwards, offset from the first connecting block. After the second connecting block moves below the first connecting block, the second ring is rotated again, aligning the first connecting block with the second connecting block. The springs deform elastically, causing the positioning pin to pass through the positioning hole. Multiple fins are stacked, and the heat from the electronic components is transferred to the heat pipes and fins. Then, the motor is started, causing the fan blades to rotate. Multiple fan blades in different directions can dissipate heat in multiple directions, achieving the effect of facilitating the splicing and locking of multiple fins, facilitating the installation and removal of fins, and simultaneously providing multi-directional heat dissipation, thus improving the heat dissipation effect.

[0035] Please see Figures 1 to 8 The embodiments provided by this utility model are as follows:

[0036] Example: A splicing and locking structure for a split-type heat sink, comprising:

[0037] The heat sink base 9 has a positioning rod 7 installed at the center of its upper end. A heat pipe 8 is installed on the outer wall of the heat sink base 9. An installation plate 10 is installed through the heat pipe 8. The upper end of the heat pipe 8 passes through the fin 12. The positioning rod 7 can be detached and passes through the center of the fin 12 for splicing and locking the fin 12.

[0038] An arc-shaped plate 1 is installed on the outer wall of the heat dissipation base 9. An mounting plate 1 2 is installed on the upper end of the arc-shaped plate 1. A mounting hole 3 is opened at the front end of the mounting plate 1 2. A mounting plate 2 5 is provided on the inner wall of the mounting hole 3. A fan blade 6 is rotatably installed at the rear end of the mounting plate 2 5, which is used to dissipate heat from multiple angles to the fins 12.

[0039] In the example of this application, the positioning rod 7 installed at the center of the upper end of the heat sink base 9 serves as a splicing and locking mechanism. It can be detachably inserted through the center of the fin 12, which not only makes the installation and removal of the fin 12 more convenient and facilitates subsequent maintenance, replacement or cleaning operations, but also positions the fin 12 to ensure that multiple fins 12 maintain good coaxiality and regularity during splicing, and avoids affecting the heat dissipation effect due to the offset of the fins 12.

[0040] Meanwhile, the heat pipe 8 installed on the outer wall of the heat sink 9 is an important channel for heat transfer. It passes through the mounting plate 10 and extends upward through the fins 12. The through-type installation method allows the heat generated on the heat sink 9 to be quickly and efficiently transferred to the mounting plate 10 and fins 12 through the heat pipe 8. Then, the heat is dissipated to the surrounding environment through the large heat dissipation surface of the fins 12, effectively improving the overall heat dissipation efficiency.

[0041] In addition, the arc-shaped plate 1 installed on the outer wall of the heat sink base 9 provides a stable support for the mounting plate 2, and the mounting hole 3 at the front end of the mounting plate 2 provides a suitable space for the installation of the mounting plate 5. The fan blade 6, which can be rotatably installed at the rear end of the mounting plate 5, dissipates heat from the fins 12, ensuring that all areas of the fins 12 receive sufficient airflow, improving the heat dissipation effect and preventing the overall heat dissipation performance of the heat sink from being affected by local heat accumulation.

[0042] Furthermore, the upper end of the mounting plate 10 has a circular hole 24, the upper end of the heat pipe 8 passes through the circular hole 24, and the outer wall of the heat pipe 8 is fixed to the inner wall of the circular hole 24.

[0043] As a preferred example of this utility model, the upper end of the heat pipe 8 passes through the circular hole 24, and the outer wall of the heat pipe 8 is fixedly connected to the inner wall of the circular hole 24, making the installation of the heat pipe 8 on the mounting plate 10 more stable and reliable. This effectively avoids the heat pipe 8 from becoming loose between the mounting plate 10 due to vibration or other external forces during the use of the heat sink, thereby affecting the stability of heat transfer.

[0044] Meanwhile, the heat transfer path has been further optimized. The heat transferred from the heat sink 9 to the heat pipe 8 can be transferred to the mounting plate 10 more efficiently through the part fixedly connected to the mounting plate 10. This allows the mounting plate 10 to also participate in the heat dissipation process, increasing the heat dissipation area and improving the overall heat dissipation capacity. This ensures that the heat sink can maintain good heat dissipation during long-term operation and avoids affecting the normal operation of the equipment due to heat accumulation.

[0045] Furthermore, a spring 11 is installed at the lower end of the fin 12, and a circular hole 16 is opened at the upper end of the fin 12. The upper end of the heat pipe 8 passes through the circular hole 16 in the vertical direction. The lower end of the spring 11 is attached to the mounting plate 10. Among the fins 12 that are stacked along the height direction of the heat dissipation base 9, the lower end of the spring 11 installed at the lower end of the upper fin 12 is attached to the upper end surface of the lower fin 12.

[0046] As a preferred example of this utility model, the lower end of the spring 11 is attached to the mounting plate 10. Among the fins 12 that are stacked along the height direction of the heat dissipation base 9, the lower end of the spring 11 mounted on the lower end of the upper fin 12 is attached to the upper end surface of the lower fin 12. The stacked spring 11 support structure ensures that each fin 12 is subjected to a uniform elastic support force.

[0047] The elastic support can effectively buffer the impact force that may be generated during installation or use, prevent the fins 12 from being damaged due to excessive force, and protect the structural integrity of the fins 12. On the other hand, the elasticity of the spring 11 can ensure that the adjacent fins 12 maintain an appropriate distance, prevent the fins 12 from sticking together and reducing the heat dissipation area, and can also automatically adjust the distance between the fins 12 according to the actual situation, ensuring that the airflow can flow smoothly between the fins 12 and improve the heat dissipation efficiency.

[0048] The circular hole 16 at the upper end of the fin 12 allows the upper end of the heat pipe 8 to pass through the fin 12 vertically. This passage method further strengthens the connection stability between the heat pipe 8 and the fin 12, and also ensures that heat can be quickly and evenly transferred from the heat pipe 8 to all parts of the fin 12, so that the fin 12 can give full play to its heat dissipation function and improve the overall heat dissipation effect.

[0049] Furthermore, the vertical center of the spring 11 is coaxial with the vertical center of the circular hole 16 opened in the fin 12.

[0050] As a preferred example of this utility model, the coaxial design allows the supporting force of the spring 11 on the fin 12 to be evenly distributed around the circular hole 16, avoiding uneven force on the fin 12 due to the offset of the spring 11 installation position, which could lead to tilting or deformation, and ensuring that the fin 12 can maintain a good structural shape and installation accuracy during long-term use.

[0051] The coaxial alignment allows the working areas of the spring 11 and heat pipe 8 on the fins 12 to be relatively concentrated, reducing interference with the heat transfer from the heat pipe 8 to the fins 12. This ensures that heat can be transferred more smoothly from the heat pipe 8 through the area around the circular hole 16 to the entire fins 12, and then efficiently dissipated through the fins 12. At the same time, the uniform support force also ensures that the spacing between the fins 12 is more uniform, further optimizing the airflow path, improving heat dissipation efficiency, and ensuring the stability and reliability of the overall heat dissipation performance of the heat sink.

[0052] Furthermore, a second round hole 17 is provided at the upper end of the fin 12, and the upper end of the positioning rod 7 passes through the second round hole 17.

[0053] As a preferred example of this utility model, the second circular hole 17 is configured as a through channel for the positioning rod 7, ensuring that the positioning rod 7 can pass through the fin 12 more stably and preventing the fin 12 from shaking or shifting during installation or use.

[0054] This design ensures that the multiple stacked fins 12 maintain a high degree of regularity and coaxiality under the action of the positioning rod 7. This guarantees that each fin 12 is accurately positioned in its preset location, preventing any deviation in fin position from affecting the contact between the heat pipe 8 and the fins 12, thus ensuring efficient heat transfer. Simultaneously, stable positioning provides a solid foundation for subsequent multi-angle heat dissipation by the fan blades 6, ensuring that airflow is evenly distributed across each fin 12, improving overall heat dissipation, and guaranteeing stable and efficient operation of the heat sink under various working conditions.

[0055] Furthermore, a ring 13 is installed on the upper end of the fin 12. A ring hole 19 is opened on the upper end of the ring 13, and a bearing 14 is installed in the ring hole 19. A ring 25 is rotatably connected in the bearing 14. A ring hole 28 is opened on the upper end of the ring 25, and a connecting block 23 is installed in the inner cavity of the ring hole 28. A positioning post 21 is fixed on the upper end of the connecting block 23. A connecting block 20 is fixed on the outer wall of the positioning rod 7, and the positioning post 21 passes through the connecting block 20.

[0056] As a preferred example of this utility model, the connecting block 23 installed in the inner cavity of the annular hole 18 at the upper end of the second ring 15, and the positioning post 21 fixed at the upper end of the connecting block 23, form a cleverly fitting structure with the connecting block 20 fixed to the outer wall of the positioning rod 7. The design of the positioning post 21 penetrating through the connecting block 20 allows for a tighter and more flexible connection between the positioning rod 7 and the fin 12 through this rotational positioning structure.

[0057] Not only can it further enhance the fixing effect of the positioning rod 7 on the fin 12, ensuring that the fin 12 will not loosen or shift during installation and use, but it can also adjust the relative position of the positioning post 21 and the connecting block 20 by rotating the ring 2 15, thereby achieving fine adjustment of the angle of the fin 12, so that the fin 12 can better adapt to different heat dissipation requirements, optimize the heat dissipation direction, and improve heat dissipation efficiency. At the same time, it also provides greater flexibility for the installation and maintenance of the fin 12.

[0058] Furthermore, the second connecting block 23 is located below the first connecting block 20, and the first connecting block 20 has a positioning hole 22 at its upper end, with the top of the positioning post 21 penetrating through the positioning hole 22.

[0059] As a preferred example of this utility model, the top of the positioning post 21 passes through the positioning hole 22, which creates a longer mating length between the positioning post 21 and the connecting block 20, greatly increasing the connection strength between the two. This effectively prevents the positioning post 21 and the connecting block 20 from separating or loosening due to external forces during use, ensuring that the connection between the positioning rod 7 and the fin 12 remains stable and reliable at all times.

[0060] The position of connecting block 23 below connecting block 1 20, combined with the design of positioning post 21 penetrating positioning hole 22, can limit the relative position of connecting block 1 20 and connecting block 23, thereby ensuring a more accurate relative position between positioning rod 7 and fin 12, avoiding any impact on the splicing effect and heat dissipation performance of fin 12 due to positional deviation. This provides a strong guarantee for the stable operation of the entire heat sink, ensuring that the heat sink can continuously and efficiently perform its heat dissipation function.

[0061] Furthermore, a motor 4 is installed at the front end of the mounting plate 2 5, and the drive end of the motor 4 is connected to the fan blade 6.

[0062] As a preferred example of this utility model, the motor 4 mounted at the front end of mounting plate 2 5 provides a stable and continuous power source for the rotation of the fan blade 6. The drive end of the motor 4 is connected to the fan blade 6, enabling the motor 4 to directly drive the fan blade 6 to rotate. This direct drive method reduces energy loss during power transmission and ensures that the power generated by the motor 4 can be converted into the rotational kinetic energy of the fan blade 6 to the maximum extent, thereby improving the rotational efficiency and speed stability of the fan blade 6.

[0063] Driven by the motor 4, the fan blade 6 can generate a stable and strong airflow. This airflow can act on the fin 12, accelerate the airflow on the surface of the fin 12, and thus quickly remove the heat from the fin 12, significantly improving the heat dissipation efficiency.

[0064] In this embodiment, when it is necessary to dissipate heat from electronic components, the heat sink 9 is first tightly attached to the surface of the electronic component to be dissipated. Through the direct contact of the heat sink 9, the heat generated by the electronic component during operation can be quickly received, preparing for subsequent heat conduction and dissipation.

[0065] Subsequently, the engagement of heat pipe 8 with circular hole 16 not only ensures that heat pipe 8 can stably penetrate fin 12, but also allows for good thermal conductivity contact between heat pipe 8 and fin 12, enabling efficient heat transfer from heat pipe 8 to fin 12. Simultaneously, positioning rod 7 is inserted through circular hole 17 at the upper end of fin 12. Circular hole 17 provides a guide channel for positioning rod 7, allowing it to stably perform initial positioning of fin 12, preventing displacement of fin 12 during subsequent installation operations and ensuring the overall neatness of the installation process.

[0066] Next, the fin 12 is pressed down with external force. Under the pressure, the spring 11 installed at the lower end of the fin 12 will undergo elastic deformation. This deformation can buffer the force generated during pressing, preventing the fin 12 from being damaged due to excessive force and protecting the structural integrity of the fin 12. On the other hand, the compression deformation of the spring 11 also provides sufficient space for subsequent positioning and locking operations. While pressing the fin 12, the second ring 15 installed at the upper end of the fin 12 is rotated. Since the second ring 15 is rotatably connected to the first ring 13 through the bearing 14, and the first ring 13 is fixed at the upper end of the fin 12, the second ring 15 can rotate smoothly within the first ring 13, and the frictional resistance during rotation is minimal. As the second ring 15 rotates, the second connecting block 23 installed in the inner cavity of the second ring hole 18 at its upper end will rotate accordingly, thereby forming a misalignment with the first connecting block 20 fixed to the outer wall of the positioning rod 7. In the misaligned state, if the fin 12 is pressed down further, the second connecting block 23 will move to the bottom of the first connecting block 20 as the fin 12 moves down.

[0067] After connecting block 23 moves below connecting block 10, rotate ring 25 again to realign connecting block 23 with connecting block 10. At this time, the spring 11, which was previously compressed, releases its elastic potential energy and generates an upward elastic force. Under the action of the elastic force, the positioning post 21 fixed at the upper end of connecting block 23 moves upward and passes through the positioning hole 22 at the upper end of connecting block 10, thus completing the positioning and locking of the single fin 12. Multiple fins 12 can be stacked. During the stacking process, the spring 11 at the lower end of the upper fin 12 will fit against the upper end face of the lower fin 12. Each fin 12 can maintain a stable and regular stacked state under the elastic support of the spring 11 and the positioning and locking action of the positioning rod 7 and the positioning post 21, ensuring that there is always an appropriate distance between adjacent fins 12, creating good conditions for subsequent heat dissipation airflow.

[0068] When the electronic components begin operation, the heat they generate is rapidly transferred through the heat sink base 9 to the heat pipes 8 mounted on the outer wall of the heat sink base 9. The heat pipes 8, with their efficient thermal conductivity, quickly transfer the heat to the various fins 12 that run through them. The fins 12 then dissipate the heat into the surrounding environment through their large heat dissipation surfaces. To further improve heat dissipation efficiency, the motor 4 mounted on the front end of the mounting plate 2 5 is activated. The drive end of the motor 4 is connected to the fan blades 6. Driven by the motor 4, the fan blades 6 rotate stably and generate a strong airflow. Since the fan blades 6 are rotatably mounted on the mounting plate 1 2 via the mounting plate 2 5, and the mounting plate 1 2 is fixed to the outer wall of the heat sink base 9 via the arc-shaped plate 1, multiple fan blades 6 can blow air from different directions to dissipate heat from the stacked fins 12. The airflow can smoothly pass through the gaps between the fins 12, quickly carrying away the heat from the surface of the fins 12, significantly improving the overall heat dissipation efficiency. This ensures that the electronic components remain within a suitable temperature range during operation, guaranteeing stable operation and extending the lifespan of the electronic components. This design facilitates the splicing and locking of multiple fins 12, makes it easy to install and remove the fins 12, and allows for multi-directional heat dissipation, thereby improving the heat dissipation effect.

[0069] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
