Description

Technical Field

[0001] The present application relates to the technical field of radiators, and in particular to a heat dissipation device and an electronic device. Background Art

[0002] With the development of semiconductor technology, the computing power of processors has been greatly improved. As the computing speed of processors increases, the heat they emit also increases. Therefore, a heat sink is usually installed near the processor to dissipate heat to prevent excessive temperature rise from causing processor abnormalities. At present, existing heat sinks mostly use a combination of fins and fans to achieve rapid heat dissipation of the processor. However, the air intake of most existing heat sinks cannot be flexibly adjusted, and the air intake flexibility is poor. When the processor is running at low load, the heat sink does not need too much air intake, and the fixed air intake method causes a certain degree of energy waste. In addition, the few heat sinks with air intake adjustment function all rely on controlling the fan speed to achieve air intake adjustment. The fan speed needs to be adjusted continuously, and the fan cannot be in the optimal speed condition for a long time. The energy consumption is high and it is not conducive to achieving the optimal performance balance. Summary of the Invention

[0003] The present application provides a heat dissipation device and an electronic device to at least solve the problems in the related art that the air intake volume of the heat dissipation device cannot be flexibly adjusted, the energy consumption is high and it is not conducive to achieving the optimal performance balance.

[0004] The present application provides a heat dissipation device, comprising: A fin heat sink is installed on the processor to dissipate heat from the processor. The fin heat sink has an air inlet side and an air outlet side for air circulation. The fan group is used to dissipate heat for the fin heat sink group to form an air flow that can enter from the air inlet side and be discharged through the air outlet side; The air volume regulating component is located on the air inlet side. The air volume regulating component includes a plurality of rotatable and adjustable fan blades. The plurality of fan blades are arranged at circumferential intervals around the horizontal axis of the air volume regulating component, and the rotation axis of the fan blades is perpendicular to the horizontal axis. The fan blades rotate to adjust the air volume on the air inlet side.

[0005] The present application also provides an electronic device, including a processor and the above-mentioned heat dissipation device, wherein the heat dissipation device is placed on the heat-generating surface side of the processor to dissipate heat from the processor.

[0006] Through the present application, since the air inlet side of the fin heat sink group is provided with an air volume regulating component, the air volume regulating component includes a plurality of fan blades that can rotate in a direction perpendicular to the horizontal axis of the air volume regulating component, the air volume regulating component can adjust the air intake by controlling the rotational opening of the fan blades. When the processor is in a low-load operating state, the fan blade opening is appropriately reduced, and when the processor is in a high-load operating state, the fan blade opening is appropriately increased. The fan blade rotation opening can be appropriately adjusted according to actual needs to achieve flexible adjustment of the air intake. Moreover, the air intake can be flexibly adjusted without directly regulating the wind speed of the fan group. The fan group can always be in the optimal speed working condition, which is conducive to reducing the energy consumption of the heat sink and achieving the optimal performance balance.

[0012] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0013] The embodiment of the present application provides a heat dissipation device, which is applied to a processor, such as Figure 1 and Figure 2As shown, it includes a fin heat sink group 1, a fan group 2 and an air volume adjustment component 3. The fin heat sink group 1 is used to cool and dissipate heat for the processor. When in use, the fin heat sink group 1 is installed on the processor and contacts the heating surface of the processor to take away the heat generated by the processor. The heat dissipation of the fin heat sink group 1 mostly adopts air cooling. The fin heat sink group 1 has an air inlet side and an air outlet side for gas circulation, so that the gas can flow into the fin heat sink group 1 to take away the heat of the fin heat sink group 1. The fan group 2 is installed on the fin heat sink group 1 and is used to dissipate heat for the fin heat sink group 1 to form an air flow that can enter from the air inlet side of the fin heat sink group 1 and can be discharged through the air outlet side of the fin heat sink group 1. Under the action of the fan group 2, a stable air flow can be formed in the fin heat sink group 1 to enhance the heat dissipation effect of the fin heat sink group 1.

[0014] Optionally, the fan group 2 of this embodiment preferably includes an intake fan 21 for air intake and an exhaust fan 22 for exhaust. The intake fan 21 is fixedly arranged on the air inlet side of the fin heat dissipation group 1, and the exhaust fan 22 is arranged on the air outlet side of the fin heat dissipation group 1. The fin heat dissipation group 1 preferably adopts a dual-fan air-cooling heat dissipation method, which can achieve the purpose of improving the heat dissipation efficiency by strengthening the gas flow. In addition, the intake fan 21 can be set only on the air inlet side of the fin heat dissipation group 1, or the exhaust fan 22 can be set only on the air outlet side of the fin heat dissipation group 1, which can also form a stable gas flow in the fin heat dissipation group 1. This embodiment preferably adopts a dual-fan method to form a strong gas flow in the fin heat dissipation group 1, and the heat dissipation efficiency is higher. Regardless of whether the above-mentioned single fan or the above-mentioned dual fan form is adopted, it falls within the protection scope of this application. The intake fan 21 and the exhaust fan 22 of this embodiment are conventional structures in the field. The specific structure and principle can refer to the existing technology.

[0015] Furthermore, the air volume regulating component 3 is located on the air inlet side of the fin heat dissipation group 1. The air volume regulating component 3 of this embodiment is preferably arranged at the front end of the air intake fan 21, that is, the air intake side of the air intake fan 21. The gas enters the air intake fan 21 through the air volume regulating component 3. In this embodiment, the air intake fan 21 is an existing product, which includes an air intake fan frame and air intake fan blades rotatably arranged in the air intake fan frame. The air volume regulating component 3 of this embodiment is detachably connected to the air intake fan 21, and can be fixedly installed on the air intake fan frame by bolt fasteners. The air volume regulating component 3 includes a plurality of rotatable and adjustable blades 31. As shown in FIG. Figure 3 As shown, Figure 3The X direction shown is the horizontal axis direction of the air volume regulating component 3. In this embodiment, a plurality of fan blades 31 are provided, and the plurality of fan blades 31 are arranged at intervals in the circumferential direction around the horizontal axis of the air volume regulating component 3. The rotation axis of the fan blade 31 is perpendicular to the horizontal axis, and it can rotate toward the air inlet side close to the fin heat dissipation group 1 to adjust the air intake on the air inlet side by adjusting the rotation opening of the fan blade 31. It can be understood that this embodiment adjusts the air intake volume by controlling the rotation of the fan blades 31. When the processor is in a high-load operating state, the processor's heat dissipation demand for the fin heat dissipation group 1 increases, and the air volume adjustment component 3 can increase the opening of the fan blades 31 by adjusting the rotation of the fan blades 31 to meet the high air intake demand. When the processor is in a low-load operating state, the processor's heat dissipation demand for the fin heat dissipation group 1 is not high, and the air volume adjustment component 3 can reduce the opening of the fan blades 31 by adjusting the rotation of the fan blades 31 to meet the low air intake demand, thereby realizing intelligent management of the air intake volume, improving the air intake flexibility on the air inlet side of the heat dissipation device, and reducing the energy consumption of the heat dissipation device, so as to help the heat dissipation device achieve the best energy consumption balance. Furthermore, since the plurality of fan blades 31 are arranged at circumferential intervals around the horizontal axis of the air volume regulating component 3 and rotate in a direction perpendicular to the horizontal axis, when air is taken in, the gas can flow in through the gap between two adjacent fan blades 31. The fan blades 31 can also play a guiding role in guiding the gas to form a vortex to a certain extent, so that the gas can enter the fin heat dissipation group 1 in the form of a vortex, which can regulate the air intake volume while helping to increase the intake flow rate, thereby improving the heat dissipation effect.

[0016] It is worth noting that in some usage scenarios, the flexible adjustment of the air intake volume can be achieved by controlling the rotational opening of the fan blades 31 in the air volume adjustment component 3, and the fan group 2 can always be in the optimal speed working condition, so as to further reduce energy consumption and achieve efficiency balance. It is understandable that there is currently a method of directly controlling the speed of the fan motor to achieve the regulation of the air intake volume, such as reducing the speed of the fan motor in low air volume scenarios and increasing the speed of the fan motor in high air volume scenarios, but this method requires continuous real-time control of the fan motor speed. Frequent control of the fan speed will lead to current consumption, which will increase energy consumption, and repeated frequent control of the fan motor speed will also reduce the service life of the fan motor to a certain extent. In this embodiment, the intelligent adjustment of the air intake volume can be achieved by controlling the rotational opening of the fan blades 31 in the air volume adjustment component 3, which can keep the fan group 2 in the optimal speed working condition range. The rotational opening of the fan blades 31 is adjusted according to the actual heat dissipation requirements of the processor to regulate the air intake volume, avoiding directly controlling the speed and start and stop of the fan group 2, which can effectively reduce energy consumption, achieve efficiency balance and improve the service life of the fan group 2.

[0017] Furthermore, if Figure 3 and Figure 4As shown, the air volume regulating assembly 3 also includes a base 32 and a drive assembly 33. Specifically, the base 32 is fixedly mounted on the air intake fan 21, and the fan blades 31 are rotatably mounted in the base 32. The drive assembly 33 is used to drive the fan blades 31 to rotate, so as to realize the rotation of the fan blades 31. It is worth noting that the heat dissipation device of the present application is intended to achieve low power consumption rather than zero energy consumption. Although the rotation of the fan blades 31 also depends on the electric drive of the drive assembly 33, the energy consumption of the drive assembly 33 driving the rotation of the fan blades 31 is almost negligible compared with the high-speed movement and high output power of the fan motor. The reason is that the fan motor needs to run at a high speed continuously, and after the drive assembly 33 of the present application drives the fan blades 31 to rotate to a suitable opening angle, the drive assembly 33 can be in a shutdown state until the air intake demand of the processor changes, and the air intake needs to be increased or decreased. The drive assembly 33 then drives the fan blades 31 to rotate to a suitable opening angle in response to the action. That is, the fan motor needs to run continuously, while the drive component 33 operates intermittently and only starts to run when the demand changes. In addition, driving the fan blades 31 to rotate does not consume much electricity. Therefore, the energy consumption of the drive component 33 to drive the fan blades 31 to rotate is almost negligible compared with the energy consumption of the fan motor.

[0018] Optionally, the driving assembly 33 in this embodiment includes but is not limited to the following two methods to drive the fan blades 31 to rotate: Method 1: There are multiple drive assemblies 33, and multiple drive assemblies 33 are connected to multiple fan blades 31 in a one-to-one correspondence. In this method, the drive assembly 33 is a conventional drive motor, and the drive assembly 33 is also arranged at intervals along the circumference of the base 32. The rotation output end of a drive assembly 33 is directly connected to a fan blade 31, and multiple drive assemblies 33 are controlled by synchronous start and stop to achieve the synchronous rotation of multiple fan blades 31. Although this method can also achieve the synchronous rotation of multiple fan blades 31, it is necessary to set up multiple drive assemblies 33 according to the number of fan blades 31. Compared with the subsequent method 2, the control method of method 1 has a high cost and a complex control process. It is necessary to control the synchronous action of multiple drive assemblies 33 and has a high failure rate. However, method 1 has the advantages of high control accuracy and fast response speed. Method 1 and method 2 each have their own advantages and can achieve the effect of rotating the fan blades 31. The choice is made according to actual needs. In this embodiment, the structure of the drive assembly 33 preferably adopts the following method 2 to reduce cost and power consumption as much as possible.

[0019] Method 2: If Figure 3 and Figure 4 As shown, Figure 3 and Figure 4The X direction is the horizontal axis direction of the air volume regulating assembly 3. The base 32 of this embodiment is a hollow annular structure as a whole. The fan blades 31 have a fan shaft 311 extending perpendicular to the horizontal axis. The multiple fan blades 31 are arranged along the circumference of the horizontal axis. The fan shaft 311 is rotatably connected to the base 32. The driving assembly 33 includes a first driving device 331, a rotating ring 332, multiple transmission rod groups 333 and multiple guide wheels 334. The multiple guide wheels 334 are arranged at intervals around the circumference of the base 32, as shown in FIG. Figure 6 As shown, the rotating ring 332 is rollingly connected to a plurality of guide wheels 334, and the plurality of guide wheels 334 are used to guide and support the rotating ring 332 so that the rotating ring 332 can rotate stably relative to the base 32. The transmission rod group 333 is arranged in a one-to-one correspondence with the fan blade 31, and the transmission rod group 333 includes a first transmission rod 3331 and a second transmission rod 3332 that are rotatably connected. The first transmission rod 3331 is fixedly connected to the fan blade shaft 311, and the second transmission rod 3332 is rotatably connected to the rotating ring 332. The first driving device 331 is connected to a fan blade shaft 311, and the first driving device 331 can drive the rotating ring 332 to rotate through the transmission rod group 333 on the fan blade shaft 311. When the rotating ring 332 rotates, it can drive the remaining multiple transmission rod groups 333 to move synchronously, so that the multiple fan blade shafts 311 rotate synchronously. There are multiple transmission rod groups 333, and the multiple transmission rod groups 333 are connected in a one-to-one correspondence with the fan blade 31. Specifically, as Figure 4 and Figure 5As shown, the transmission rod assembly 333 includes a first transmission rod 3331 and a second transmission rod 3332 rotatably connected to each other, and one end of the first transmission rod 3331 is fixedly connected to the blade rotating shaft 311. In this embodiment, one end of the second transmission rod 3332 is rotatably connected to the rotating ring 332, and one end thereof can rotate about the radial direction of the rotating ring 332 as the rotation axis, and the other end is rotatably connected to the first transmission rod 3331 and can rotate relative to the first transmission rod 3331. The rotation axis of the blade rotating shaft 311, the rotation axis of the second transmission rod 3332 at the junction with the rotating ring 332, and the rotation axis at the junction with the second transmission rod 3332 and the first transmission rod 3331 are parallel to each other and are approximately in the same direction as the radial direction of the rotating ring 332. However, the three rotation axes are arranged parallel to each other and are neither coaxial nor coplanar. The first drive device 331 is connected to a fan shaft 311. The first drive device 331 is a conventional drive motor. When it rotates, it can simultaneously drive the fan shaft 311 connected to it and the first transmission rod 3331 on the fan shaft 311 to rotate synchronously. When the first transmission rod 3331 on the fan shaft 311 rotates, the first transmission rod 3331 will push the second transmission rod 3332 connected to it so that the second transmission rod 3332 pushes the rotating ring 332 to rotate. Since the rotating ring 332 is rotationally connected to the accommodating groove 320, the rotating ring 332 can drive the remaining multiple transmission rod groups 333 to move synchronously when it rotates. In this embodiment, the remaining multiple transmission rod groups 333 refer to the transmission rod groups 333 on the remaining fan shaft 311 that are not directly connected to the first drive device 331. Specifically, when the first driving device 331 drives the rotating ring 332 to start rotating in the above manner, the rotating ring 332 drives the remaining second transmission rod 3332 to move synchronously after rotating, and the remaining second transmission rod 3332 drives the remaining first transmission rod 3331 to rotate. When the remaining first transmission rod 3331 rotates, it drives the fan blade shaft 311 on it to rotate synchronously, so as to realize the synchronous rotation of multiple fan blade shafts 311 and the adjustment of the opening and closing angles.

[0020] In summary, the detailed operation process of the air volume adjustment assembly 3 of this embodiment is as follows: In the initial state, that is, in the shutdown state, the plurality of fan blades 31 are in a closed state, which can cover the air inlet of the intake fan 21. When the processor is in a high load operation state, such as Figure 3 and Figure 4As shown, the first drive device 331 is activated, driving the fan blade shaft 311 connected thereto and the first transmission rod 3331 on the fan blade shaft 311 to rotate coaxially. When the first transmission rod 3331 rotates, it pushes against the second transmission rod 3332 connected thereto to drive the rotating ring 332 to rotate. After the rotating ring 332 rotates, it drives the remaining second transmission rods 3332 to move accordingly. When the remaining second transmission rods 3332 move, they correspondingly drive the remaining first transmission rods 3331 to rotate, thereby achieving synchronous opening of multiple fan blades 31. When the processor is in a low-load operating state, the output end of the first drive device 331 can be reversely adjusted to achieve control of the relative closing of multiple fan blades 31 and reduce the opening angle.

[0021] Exemplarily, the drive assembly 33 of this embodiment also includes a transmission shaft, and the first drive device 331 is connected to the fan blade shaft 311 through the transmission shaft. Specifically, one end of the transmission shaft is fixedly connected to the rotation output end of the first drive device 331, and the other end of the transmission shaft is fixedly connected to the fan blade shaft 311. In addition, the transmission shaft component can also be omitted, and the rotation output end of the first drive device 331 can be directly connected to the fan blade shaft 311.

[0022] Furthermore, if Figure 3 As shown, the base 32 includes an inner base 321, an outer base 322 and a side base 323. Figure 3 The inner base 321 and the outer base 322 are partially split. The inner base 321 is an annular structure with a hollow and through internal cavity. The fan blade 31 is located in the internal cavity. The outer base 322 is an annular thin-walled structure. The inner base 321 and the outer base 322 are coaxially arranged. The side base 323 is connected to the inner base 321 and the outer base 322 to form a receiving groove 320. The inner base 321, the outer base 322 and the side base 323 of this embodiment can be designed as an integral part. The fan blade shaft 311 is rotatably connected to the inner base 321, and one end of the fan blade shaft 311 rotatably connected to the inner base 321 extends into the receiving groove 320. The rotating ring 332, the transmission rod group 333 and the guide wheel 334 are all placed in the receiving groove 320. The guide wheel 334 is rotatably connected to the receiving groove 320. Specifically, as shown in FIG. Figure 6 As shown, a guide wheel shaft is protruding from the axis of the guide wheel 334, and guide wheel shaft holes are provided on the opposite side walls of the receiving groove 320. The guide wheel shaft is rotatably connected to the guide wheel shaft hole to realize the rotation connection between the guide wheel 334 and the receiving groove 320. Preferably, as Figure 6As shown, in this embodiment, the guide wheel 334 is formed with a first limiting protrusion 3341 and a second limiting protrusion 3342 at both axial ends. Both the first limiting protrusion 3341 and the second limiting protrusion 3342 are circular boss structures. The first and second limiting protrusions 3341, 3342 respectively abut against opposite axial sides of the rotating ring 332. The first and second limiting protrusions 3341, 3342 effectively prevent the rotating ring 332 from slipping off the guide wheel 334, thereby improving the rotational reliability of the rotating ring 332.

[0023] Alternatively, as Figure 3 As shown, a support for supporting and fixing the first driving device 331 is further provided on the top of the outer base 322 of this embodiment, so as to fix the first driving device 331 .

[0024] Furthermore, if Figure 3 As shown, the base 32 further includes a separator 324, which is disposed within the inner base 321 to divide the internal cavity of the inner base 321 into a plurality of independent flow openings 3210. Each flow opening 3210 is provided with at least one corresponding blade 31 for rotation to cover the flow opening 3210. It will be understood that the separator 324 of this embodiment can further divide the interior of the inner base 321 into a plurality of circumferentially arranged and independent flow openings 3210, which, while partitioning, also facilitates guiding the wind direction to form a vortex effect.

[0025] More specifically, if Figure 3 As shown, the separator 324 includes a connecting column 3241 and a plurality of partitions 3242 arranged at intervals along the circumference of the inner base 321. The connecting column 3241 is located at the axis of the inner base 321. One end of the partition 3242 is connected to the connecting column 3241, and the other end is connected to the inner base 321. A flow port 3210 is formed between two adjacent partitions 3242. In this embodiment, four partitions 3242 are provided. The four circumferentially arranged partitions 3242 separate the inner base 321 into four independent flow ports 3210. In this embodiment, eight fan blades 31 are provided. Two fan blades 31 are rotatably provided at each flow port 3210. In addition, eight flow ports 3210 can be formed in the inner base 321. Only one fan blade 31 is rotatably provided at each flow port 3210. The design selection is based on actual conditions, including but not limited to the attached embodiment of this embodiment. Figure 3 Furthermore, the blade shaft 311 of each blade 31 is rotatably connected to the connecting post 3241 , one end of the blade shaft 311 is rotatably connected to the inner base 321 , and the other end is rotatably connected to the connecting post 3241 , so as to achieve stable rotation of the blade 31 .

[0026] Alternatively, as Figure 1As shown, the air volume regulating assembly 3 further includes a protective net 34 , which is arranged on the base 32 and specifically fixedly connected to the outer base 322 . The protective net 34 is used to block foreign matter to prevent foreign matter from entering the base 32 and interfering with the rotation of the fan blades 31 .

[0027] Preferably, the heat dissipation device of this embodiment further includes a wind direction adjustment component 4, such as Figure 1 and Figure 2 As shown, the wind direction adjustment component 4 is located on the outlet side of the fin heat sink group 1, specifically on the outlet side of the exhaust fan 22. It can adjust the airflow direction on the outlet side, thereby adjusting the direction of the exhaust gas, optimizing the gas flow path, ensuring that hot air can be effectively and quickly discharged, avoiding hot air retention, achieving effective exhaust, and improving heat dissipation efficiency. This embodiment optimizes the air intake control on the air inlet side of the fin heat sink group 1 and optimizes the wind direction on the outlet side of the fin heat sink group 1, thereby simultaneously adjusting and improving the heat dissipation effect.

[0028] Specifically, if Figure 7 and Figure 9 As shown, the wind direction adjustment assembly 4 includes a first annular frame 41, a second annular frame 45, and a plurality of grilles 42 spaced apart within the first annular frame 41. The first annular frame 41 is rotatable relative to the second annular frame 45. During use, the first annular frame 41 can be rotated to cause the grilles 42 therein to rotate synchronously, thereby achieving wind direction adjustment on the air outlet side.

[0029] Furthermore, if Figure 7 As shown, the grille 42 can rotate relative to the first annular frame 41 to further adjust and change the wind direction. There are multiple grilles 42 spaced apart and evenly spaced in the same direction. The multiple grilles 42 are rotatably connected to the first annular frame 41. A rotating shaft is provided at both ends of the length direction of each grille 42. The grille 42 is rotatably connected to the first annular frame 41 via the rotating shaft. Preferably, the wind direction adjustment component 4 of this embodiment includes a transfer rod 43 and a second drive device 44, which drives the multiple grilles 42 to rotate synchronously through the second drive device 44 and the transfer rod 43. Figure 7 and Figure 8 The transfer rod 43 is rotatably connected to the plurality of grilles 42, and the second drive device 44 is rotatably connected to the first annular frame 41. The second drive device 44 has a movable telescopic end 441, and the movable telescopic end 441 is rotatably connected to the transfer rod 43. The second drive device 44 of this embodiment is an electric push rod, which pushes the transfer rod 43 by telescopically regulating the movable telescopic end 441 of the second drive device 44. The movement of the transfer rod 43 drives the plurality of grilles 42 to flip synchronously to achieve wind direction adjustment of the air outlet.

[0030] Furthermore, if Figure 7As shown, the grille 42 of this embodiment is provided with an avoidance groove 421, which provides a mounting position for the transfer rod 43, and the transfer rod 43 extends into the avoidance groove 421. One of the surfaces of the avoidance groove 421 and the transfer rod 43 has a corresponding through-hole, and the other surface has a corresponding support shaft. The support shaft is rotatably connected to the through-hole to achieve flexible adjustment between the transfer rod 43 and the multiple grilles 42. Exemplarily, the transfer rod 43 is provided with a through-hole that passes through the thickness direction of the transfer rod 43, and the avoidance groove 421 is provided with a support shaft that passes through the through-hole. Alternatively, the avoidance groove 421 has a through-hole. Preferably, the inner walls on both sides of the avoidance groove 421 have through-holes, and the opposite side walls of the transfer rod 43 are provided with support shafts that are connected to the through-holes in a one-to-one manner.

[0031] Furthermore, if Figure 9 As shown, the wind direction adjustment component 4 of this embodiment includes a third drive device 46 and a gear 47. The outer periphery of the first annular frame 41 is continuously distributed with external teeth 411, and the gear 47 is engaged with the external teeth 411. The third drive device 46 is driven and connected to the gear 47 to drive the first annular frame 41 to rotate in the second annular frame 45. The third drive device 46 of this embodiment is a drive motor. The rotation output end of the third drive device 46 is directly connected to the gear 47. Since the outer periphery of the gear 47 is distributed with external teeth 411, and the gear 47 is engaged with the external teeth 411, when the third drive device 46 rotates, it can drive the first annular frame 41 to rotate synchronously, so as to achieve adjustable rotation angle of the first annular frame 41. Optionally, in this embodiment, the maximum rotation angle of the first annular frame 41 in the second annular frame 45 is 180°. The rotation direction of the first annular frame 41 can be adjusted by rotating the third drive device 46 forward and reverse.

[0032] Furthermore, if Figure 9 As shown, the second annular frame 45 of this embodiment includes a main frame body 451 and a sub-frame body 452. The main frame body 451 is connected to the sub-frame body 452. The sub-frame body 452 is used to accommodate the gear 47, which is rotatably connected to the sub-frame body 452. A limiting groove is provided in the main frame body 451. The first annular frame 41 is slidably connected to the limiting groove and is limited within the limiting groove. The external teeth 411 distributed on the outer circumference of the first annular frame 41 extend into the limiting groove. The third driving device 46 can be fixedly mounted on the main frame body 451 or on the sub-frame body 452. The main frame body 451 and the sub-frame body 452 of this embodiment cooperate to effectively prevent foreign matter from entering the gap between the meshing gear 47 and the external teeth 411, thereby preventing the gear 47 from getting stuck and being unable to drive the first annular frame 41 to rotate.

[0033] Alternatively, as Figure 10As shown, the fin heat sink group 1 of this embodiment includes a plurality of heat sink fins 11 stacked on each other, a heat sink pipe 12 passing through the plurality of heat sink fins 11, and a fixing seat 13 for fixing the heat sink 12 to a specified position. In this embodiment, the heat sink 12 is in contact with the heating surface of the processor, and the heat sink 12 is fixed to the heating surface of the processor by the fixing seat 13. Heat is transferred to each heat sink fin 11 via the heat sink 12, and the heat is released through the heat sink fin 11. A groove is provided on the bottom surface of the fixing seat 13 of this embodiment, and the shape and size of the groove are adapted to the shape and size of the groove to achieve a stable connection to the heat sink 12. In addition, the fin heat sink group 1 of this embodiment may also adopt other structural forms, including but not limited to the structure shown in the drawings of this embodiment.

[0034] It should be noted that the heat dissipation device of this embodiment adopts an independent modular design as a whole. The fan group 2, the air volume adjustment component 3 and the wind direction adjustment component 4 operate independently. When the fan group 2, the air volume adjustment component 3 or the wind direction adjustment component 4 fails, they can be replaced independently, reducing maintenance costs and downtime, and the overall operation will not be affected by the failure of a single component. The fan group 2 of this embodiment preferably includes both an intake fan 21 and an exhaust fan 22. The air volume adjustment component 3 is set outside the intake fan 21 on the air inlet side of the fin heat dissipation group 1, and the wind direction adjustment component 4 is set outside the exhaust fan 22 on the air outlet side of the fin heat dissipation group 1. This can not only adjust the air intake volume on the air inlet side of the fin heat dissipation group 1, so that the air inlet side of the fin heat dissipation group 1 can enter the interior of the fin heat dissipation group 1 in the form of vortex, but also adjust the wind direction on the air outlet side of the fin heat dissipation group 1, and can accurately adjust the airflow direction, effectively avoid local overheating, reduce the high temperature impact of the hardware, and extend the service life of the hardware. In some other embodiments, the intake fans 21 and their number, the exhaust fans 22 and their number, and the wind direction adjustment component 4 can be selectively set according to actual needs. In addition, a control module can be independently set for the heat dissipation device, which is used to regulate the direction, speed and start and stop of the first drive device 331, the second drive device 44 and the third drive device 46. According to the actual working conditions of the processor, the air volume and wind direction can be adaptively adjusted intelligently, so that it can adapt to different workloads and environmental conditions more flexibly, ensuring that the best heat dissipation effect can be provided under various circumstances. The specific control process can refer to the existing technology, and this embodiment will not list them one by one. Any design method falls within the protection scope of this application.

[0035] Furthermore, this embodiment also provides an electronic device comprising a processor and the aforementioned heat dissipation device, the heat dissipation device being disposed on the processor, on the heat-generating surface side of the processor. The heat dissipation device of this electronic device has an air intake adjustment function. By adjusting the air intake, the fan group 2 can always be kept at an optimal operating condition, achieving intelligent management of the air intake, and reducing unnecessary energy consumption. Furthermore, the air on the air intake side of the fin heat dissipation group 1 can enter the fin heat dissipation group 1 in the form of a vortex, which can adjust the air intake volume while also facilitating an increase in the air intake flow rate, thereby improving the heat dissipation effect. The specific structure and effects of the heat dissipation device can be referred to above, and will not be further described in this embodiment.

Specific examples are used herein to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method and core idea of the present application.
