Description

Technical Field

[0001] The utility model relates to the technical field of electronic devices, in particular to a super silent and ultra-thin fan and an electronic terminal device. Background Art

[0002] With the popularization and continuous improvement of the performance of smart phones, when a mobile phone runs high-performance applications, especially large games, it is prone to overheating. This not only affects the user's hand feeling comfort, but may also lead to a decline in the performance of the mobile phone and even damage to the mobile phone hardware. To address this problem, various mobile phone heat dissipation solutions have emerged on the market, and the most common one is an external mobile phone fan. However, the external fan has many inconveniences in actual use, such as occupying the mobile phone interface and affecting the portability of the mobile phone, and cannot fully meet the user's needs.

[0003] In some traditional technical solutions, there is a design of adding a fan to electronic terminal devices such as mobile phones, but these traditional mobile phones with built-in fans have problems that the fans are prone to damage and have a short service life.

[0004] The above information disclosed in the background art of this application is only used to understand the background of the concept of this application and may include information that does not constitute the prior art. Summary of the Utility Model

[0005] Based on this, in view of the above problems, it is necessary to provide a super silent and ultra-thin fan and an electronic terminal device.

[0006] A super silent and ultra-thin fan for dissipating heat from an electronic terminal device, comprising:

[0007] A base, on which a limiting post is provided, a limiting groove is opened in the limiting post, and a receiving cavity is opened at the bottom of the limiting groove;

[0008] A wear-resistant member, which is embedded in the receiving cavity;

[0009] A fan, the fan includes an impeller and a rotating shaft connected to the impeller, the rotating shaft is rotatably inserted into the limiting groove, and the free end of the rotating shaft abuts against the wear-resistant member; and

[0010] A driving assembly, which is arranged on the base and is used to drive the fan to rotate.

[0011] The beneficial effects that the above ultra - quiet and ultra - thin fan can achieve at least are as follows: Its design fully considers the limitations of the internal space of electronic terminal devices. Through reasonable layout and precise design, the fan and other components can be compactly integrated into the host, without affecting the overall size and portability of the device. By setting an ultra - quiet and ultra - thin fan in the host, especially by adopting the combined design of the fan and wear - resistant parts, the heat dissipation efficiency can be significantly improved, the operating temperature of the electronic terminal device can be rapidly reduced, and it is ensured that the device can still operate stably under high load. It can be understood that if the rotating shaft is suspended, or the structure of the rotating shaft directly contacts the base, resulting in wear of the part of the base in contact with the rotating shaft, the end of the rotating shaft cannot maintain a butting state with the base, and the rotating shaft and the impeller connected to the rotating shaft will have problems of instability and easy shaking, and the fan is more likely to be damaged, resulting in a shorter service life. However, in this application, a wear - resistant part is added and embedded in the accommodating cavity to abut against the free end of the rotating shaft, which can provide wear - resistant effect, ensure the stability of the relative position of the rotating shaft, and thus extend the service life of the fan and the entire ultra - quiet and ultra - thin fan.

[0012] In one embodiment, the ultra - quiet and ultra - thin fan further includes a bearing. The bearing is embedded in the limiting groove, the outer ring of the bearing is fixed to the groove wall of the limiting groove, and the rotating shaft passes through the inner ring of the bearing and is fixed to the inner ring of the bearing. By embedding a bearing in the limiting groove and fixing the rotating shaft to the inner ring of the bearing, the stability of the fan during high - speed rotation can be significantly improved, vibrations and offsets can be reduced, and it is ensured that the fan runs continuously and smoothly. The use of the bearing avoids direct friction between the rotating shaft and the limiting groove, reduces wear, and thus extends the service life of the fan and the entire ultra - quiet and ultra - thin fan. The low - friction characteristic of the bearing also enables the fan to rotate more efficiently, increases the rotational speed and heat dissipation effect of the fan, and further improves the heat dissipation performance of the electronic terminal device. In addition, the bearing can preferably be a silent bearing to reduce the noise generated by friction, and can also reduce the noise of the fan during high - speed rotation through its smooth operation characteristics, improving the user experience.

[0013] In one embodiment, the fan further includes a mounting cover. The impeller is sleeved on the outer circumferential surface of the mounting cover, and the rotating shaft is connected to the center of the mounting cover and is located on the side of the mounting cover facing the base. By adding a mounting cover in the fan and sleeving the impeller on the outer circumferential surface of the mounting cover, additional support and fixation can be provided, enhancing the stability of the overall structure of the fan, and preventing the impeller from shifting or deforming during high - speed rotation. The mounting cover provides a structure that is convenient for installation and disassembly. The impeller and the rotating shaft are fixedly connected through the mounting cover, simplifying the installation and maintenance process of the fan, reducing the maintenance cost and difficulty. The mounting cover can also effectively prevent dust and debris from entering the fan interior, protect key components such as the rotating shaft and the impeller, and keep the fan running efficiently for a long time.

[0014] In one embodiment, the mounting cover covers the driving assembly and there is a gap between the mounting cover and the driving assembly. The driving assembly includes a bracket fixedly sleeved on the limiting post and a first magnetic member connected to the bracket. The fan further includes a second magnetic member disposed in the mounting cover. The second magnetic member is disposed in the mounting cover and can drive the mounting cover, the impeller and the rotating shaft connected to the mounting cover to rotate under the magnetic force of the first magnetic member. The magnetic drive system has the characteristics of high efficiency and low energy consumption, can improve the operating efficiency of the fan, and further enhance the heat dissipation effect. By driving the mounting cover, the impeller and the rotating shaft to rotate through the magnetic force of the first magnetic member and the second magnetic member, compared with the traditional mechanical drive, there is almost no contact and friction during the operation, avoiding the friction and wear caused by mechanical transmission, prolonging the service life of the fan, and significantly reducing the noise, thus enhancing the user experience.

[0015] In one embodiment, the number of the first magnetic members is set to be multiple. The multiple first magnetic members are circumferentially and spacedly arranged on the bracket around the limiting post. The second magnetic member is an annular magnet, and the second magnetic member is disposed on the inner circumferential surface of the mounting cover. The multiple first magnetic members are circumferentially and spacedly arranged along the limiting post, which can provide uniform magnetic drive, enhance the overall magnetic effect, improve the driving force of the fan, ensure the stable rotation of the mounting cover, the impeller and the rotating shaft, and reduce the unbalance phenomenon. The design of the second magnetic member as an annular magnet forms a continuous magnetic force loop with the multiple first magnetic members, optimizes the magnetic field distribution, and improves the magnetic force transmission efficiency.

[0016] In one embodiment, the driving assembly further includes a control board. The control board is sleeved on the limiting post and fixed to the base. A limiting recess is formed on the control board, and a limiting protrusion is provided on the bracket. The limiting protrusion extends into the limiting recess to limit the movement of the bracket relative to the control board. The limiting protrusion extending into the limiting recess effectively limits the movement of the bracket relative to the control board, prevents the bracket and the entire driving assembly from generating displacement during operation, and improves the stability of the overall structure. The design of the limiting protrusion and the limiting recess makes the installation of the bracket and the control board more convenient, reduces the alignment difficulty during the installation process, and improves the assembly efficiency.

[0017] In one embodiment, the ultra-quiet and ultra-thin fan further includes a top cover. The top cover covers the base and is located on the side of the fan facing away from the base. An air outlet is formed on the top cover, and an air inlet is provided on the base. The air outlet on the top cover and the air inlet on the base form an effective air flow path, ensuring that air can smoothly pass through the ultra-quiet and ultra-thin fan, and improving the heat dissipation efficiency. The combined design of the top cover and the base improves the overall structural strength of the ultra-quiet and ultra-thin fan, and enhances the durability and reliability of the device.

[0018] In one embodiment, the cross-sectional profile of the air outlet is smaller than that of the impeller. The cross-sectional profile of the air outlet being smaller than that of the impeller means that even if the impeller becomes detached, it cannot escape through the air outlet of the top cover, providing a limiting and protective function.

[0019] In one embodiment, a first clamping member is provided on the base, and a second clamping member is provided on the top cover. The top cover is clamped to the base through the cooperation of the first clamping member and the second clamping member. Through the design of the clamping members, the installation and disassembly of the top cover and the base become more convenient, without the need for additional tools, greatly simplifying the operation steps.

[0020] In one embodiment, the wear-resistant member is in a sheet shape.

[0021] In one embodiment, the wear-resistant member is a mylar sheet.

[0022] The present application also provides an electronic terminal device, which includes a main body and the ultra-quiet and ultra-thin fan as described in any of the above embodiments. The ultra-quiet and ultra-thin fan is disposed within the main body.

[0023] For the above-mentioned electronic terminal device, since it includes the ultra-quiet and ultra-thin fan as described in any of the above embodiments, the electronic terminal device also has at least the following beneficial effects: Its design fully considers the limitations of the internal space of the electronic terminal device. Through reasonable layout and precise design, the fan and other components can be compactly integrated within the main body without affecting the overall size and portability of the device. By providing the ultra-quiet and ultra-thin fan within the main body, especially by adopting the combined design of the fan and the wear-resistant member, the heat dissipation efficiency can be significantly improved, rapidly reducing the operating temperature of the electronic terminal device and ensuring stable operation of the device under high loads. It can be understood that if the rotating shaft is suspended, or if the structure of the rotating shaft directly contacts the base, resulting in wear of the part of the base in contact with the rotating shaft, the end of the rotating shaft will not be able to maintain a butting state with the base, and the rotating shaft and the impeller connected to the rotating shaft will have problems of instability and easy shaking, and the fan is more likely to be damaged, resulting in a shorter service life. However, in the present application, a wear-resistant member is added and embedded in the receiving cavity to abut against the free end of the rotating shaft, which can provide a wear-resistant effect, ensuring the stability of the relative position of the rotating shaft, thereby extending the service life of the fan and the entire ultra-quiet and ultra-thin fan.

[0024] In one embodiment, the electronic terminal device further includes a temperature sensor disposed within the host. The temperature sensor can monitor the temperature changes inside the host in real time, providing accurate temperature data to help timely understand the operating condition of the device. Combining the data of the temperature sensor, the electronic terminal device can achieve intelligent heat dissipation control, adjusting the fan speed or other heat dissipation measures according to the actual temperature to ensure that the device operates within the optimal temperature range, improving performance stability and avoiding performance degradation or failures caused by overheating. The temperature sensor can issue an alarm or automatically take cooling measures when the device temperature is too high to prevent the device from overheating, protect internal components, and extend the service life of the device. Through the data of the temperature sensor, the device can reduce the fan speed or turn off some super quiet and ultra-thin fans when the temperature is low, thereby reducing energy consumption and achieving energy-saving effects.

[0025] In one embodiment, the electronic terminal device further includes a circuit board and a battery disposed within the host. The heat generated during the operation of the circuit board and the battery can be promptly conducted and dissipated by the super quiet and ultra-thin fan, thereby ensuring that the device operates within the optimal temperature range.

[0026] In one embodiment, a fixing groove is provided within the host, and the super quiet and ultra-thin fan is disposed within the fixing groove. The fixing groove can firmly fix the super quiet and ultra-thin fan, preventing its position deviation caused by vibration or movement during the operation of the device, and ensuring that the super quiet and ultra-thin fan is always in the optimal working position. The design of the fixing groove simplifies the installation and maintenance process of the super quiet and ultra-thin fan. The user only needs to insert the super quiet and ultra-thin fan into the fixing groove, which is convenient and fast, reducing the operation difficulty. The fixing groove can ensure that the super quiet and ultra-thin fan is in close contact with heat sources (such as the circuit board, battery, etc.), improving the heat conduction efficiency, thereby enhancing the overall heat dissipation effect and preventing the device from overheating. The fixing groove can reduce the vibration and noise generated by the super quiet and ultra-thin fan during operation, improving the mute performance of the device and providing a quieter usage environment for the user.

Detailed implementation manners

[0038] In order to make the above objects, features, and advantages of the present utility model more obvious and understandable, the following will describe the detailed implementation manners of the present utility model in conjunction with the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0039] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6, in some embodiments, the present application provides an electronic terminal device, which includes a host 10 and a super silent and ultra-thin fan 20, and the super silent and ultra-thin fan 20 is disposed within the host 10. Among them, the super silent and ultra-thin fan 20 includes a base 100, a wear-resistant member 200, a fan 300, and a driving assembly 400. As Figure 3 and Figure 5 shown, the base 100 is provided with a limiting post 110, a limiting groove 111 is defined in the limiting post 110, and a receiving cavity 112 is formed at the bottom of the limiting groove 111; the wear-resistant member 200 is embedded in the receiving cavity 112; the fan 300 includes an impeller 330 and a rotating shaft 340 connected to the impeller 330, the rotating shaft 340 is rotatably inserted into the limiting groove 111, and the free end of the rotating shaft 340 abuts against the wear-resistant member 200; the driving assembly 400 is disposed on the base 100 and is configured to drive the fan 300 to rotate.

[0040] The beneficial effects that the present application can at least achieve are as follows: Its design fully considers the limitation of the internal space of the electronic terminal device. Through reasonable layout and precise design, the fan 300 and other components can be compactly integrated within the host 10 without affecting the overall size and portability of the device. By providing the super silent and ultra-thin fan 20 within the host 10, especially by adopting the combined design of the fan 300 and the wear-resistant member 200, the heat dissipation efficiency can be significantly improved, the operating temperature of the electronic terminal device can be rapidly reduced, and it is ensured that the device can still operate stably under high load. It can be understood that if the rotating shaft 340 is suspended, or if the structure of the rotating shaft 340 directly contacts the base 100, resulting in wear of the structure of the part where the base 100 contacts the rotating shaft 340, the end of the rotating shaft 340 will not be able to maintain an abutting state with the base 100, and the rotating shaft 340 and the impeller 330 connected to the rotating shaft 340 will have problems of instability and easy shaking, and the fan 300 is more likely to be damaged, resulting in a shorter service life. However, the present application adds a wear-resistant member 200 and embeds the wear-resistant member 200 in the receiving cavity 112 to abut against the free end of the rotating shaft 340, which can provide a wear-resistant effect, ensure the stability of the relative position of the rotating shaft 340, and thus extend the service life of the fan 300 and the entire super silent and ultra-thin fan 20.

[0041] Specifically, as Figure 3 、 Figure 5 、 Figure 6 and Figure 7As shown, in some of the embodiments, the ultra - quiet and ultra - thin fan 20 further includes a bearing 500. The bearing 500 is embedded in the limit groove 111. The outer ring of the bearing 500 is fixed to the groove wall of the limit groove 111, and the rotating shaft 340 passes through the inner ring of the bearing 500 and is fixed to the inner ring of the bearing 500. By embedding the bearing 500 in the limit groove 111 and fixing the rotating shaft 340 to the inner ring of the bearing 500, the stability of the fan 300 during high - speed rotation can be significantly improved, reducing vibration and offset, and ensuring the continuous and stable operation of the fan 300. The use of the bearing 500 avoids the direct friction between the rotating shaft 340 and the limit groove 111, reduces wear, and thus extends the service life of the fan 300 and the entire ultra - quiet and ultra - thin fan 20. The low - friction characteristic of the bearing 500 also enables the fan 300 to rotate more efficiently, increasing the rotation speed and heat dissipation effect of the fan 300, and further improving the heat dissipation performance of the electronic terminal device. In addition, the bearing 500 can preferably be a silent bearing 500 to reduce the noise generated by friction, and can also reduce the noise of the fan 300 during high - speed rotation through its smooth operation characteristics, enhancing the user experience.

[0042] Please refer to Figure 7 and Figure 8 , in some of the embodiments, the fan 300 further includes a mounting cover 310. The impeller 330 is sleeved on the outer circumferential surface of the mounting cover 310, and the rotating shaft 340 is connected to the center of the mounting cover 310 and is located on the side of the mounting cover 310 facing the base 100. Since the ultra - quiet and ultra - thin fan 20 is installed in terminal devices such as mobile phones, this application is relatively thin and light with a small size. Therefore, the rotating shaft 340 inside is very thin, and methods such as laser spot welding can be used to fix the rotating shaft 340 to the mounting cover 310, ensuring flatness, perpendicularity, and roundness. By adding the mounting cover 310 in the fan 300 and sleeving the impeller 330 on the outer circumferential surface of the mounting cover 310, additional support and fixation can be provided, enhancing the stability of the overall structure of the fan 300 and preventing the impeller 330 from shifting or deforming during high - speed rotation. The mounting cover 310 provides a structure that is convenient for installation and disassembly. The impeller 330 and the rotating shaft 340 are uniformly fixed and connected through the mounting cover 310, simplifying the installation and maintenance process of the fan 300, reducing the maintenance cost and difficulty. The mounting cover 310 can also effectively prevent dust and debris from entering the interior of the fan 300, protecting key components such as the rotating shaft 340 and the impeller 330, and keeping the fan 300 operating efficiently for a long time.

[0043] Specifically, as Figure 3As shown, in some of the embodiments, the mounting cover 310 covers the driving assembly 400 and there is a gap between the mounting cover 310 and the driving assembly 400. The driving assembly 400 includes a bracket 420 fixedly sleeved on the limiting post 110 and a first magnetic member 410 connected to the bracket 420. The fan 300 further includes a second magnetic member 320 disposed in the mounting cover 310. The second magnetic member 320 is disposed in the mounting cover 310 and can drive the mounting cover 310 and the impeller 330 and the rotating shaft 340 connected to the mounting cover 310 to rotate under the magnetic force of the first magnetic member 410. The magnetic drive system has the characteristics of high efficiency and low energy consumption, can improve the operating efficiency of the fan 300, and further enhance the heat dissipation effect. By the magnetic force of the first magnetic member 410 and the second magnetic member 320, the mounting cover 310, the impeller 330, and the rotating shaft 340 are driven to rotate. Compared with the traditional mechanical drive, there is almost no contact and friction during the operation of the magnetic drive, avoiding the friction and wear caused by mechanical transmission, prolonging the service life of the fan 300, and significantly reducing the noise, thus enhancing the user experience. It should be noted that the first magnetic member 410 may include silicon steel sheets and enameled wires disposed on the bracket 420. For example, the silicon steel sheets can be stamped into thin sheets and then stacked together to form the iron core of the stator. This iron core is the main structural part of the stator and is responsible for guiding the magnetic flux. The silicon steel sheets have high magnetic permeability and low iron loss (including hysteresis loss and eddy current loss), which helps to improve the efficiency of the motor and reduce heat generation. The enameled wires can be used to wind the windings of the stator. The windings are the key part of the stator and generate a rotating magnetic field by being energized. The enameled wires are responsible for conducting the current and generating the required magnetic field to drive the rotation of the rotor (such as the second magnetic member 320) of the motor. The insulating paint layer of the enameled wires prevents short circuits between the windings, ensuring that the current flows along the predetermined path. In addition, the insulating paint layer can also withstand high temperatures and mechanical stresses, ensuring the reliability and safety of the stator.

[0044] More specifically, as Figure 5 shown, in some of the embodiments, the number of the first magnetic members 410 is set to be multiple, and the multiple first magnetic members 410 are arranged at intervals around the circumferential direction of the limiting post 110 on the bracket 420. The second magnetic member 320 is an annular magnet steel, and the second magnetic member is disposed on the inner circumferential surface of the mounting cover 310. The multiple first magnetic members 410 are arranged at intervals along the circumferential direction of the limiting post 110, which can provide uniform magnetic drive, enhance the overall magnetic effect, can improve the driving force of the fan 300, ensure the stable rotation of the mounting cover 310, the impeller 330, and the rotating shaft 340, and reduce the unbalance phenomenon. The second magnetic member 320 adopts an annular magnet steel design, forms a continuous magnetic force loop with the multiple first magnetic members 410, optimizes the magnetic field distribution, and improves the magnetic force transmission efficiency.

[0045] More specifically, as Figure 3 , Figure 4 and Figure 5 shown, in some of the embodiments, the driving assembly 400 further includes a control board 430. The control board 430 is sleeved on the limit post 110 and fixed to the base 100. A limit recess 431 is formed on the control board 430, and a limit protrusion 421 is provided on the bracket 420. The limit protrusion 421 extends into the limit recess 431 to limit the movement of the bracket 420 relative to the control board 430. The extension of the limit protrusion 421 into the limit recess 431 effectively limits the movement of the bracket 420 relative to the control board 430, preventing the bracket 420 and the entire driving assembly 400 from generating displacement during operation and improving the stability of the overall structure. The design of the limit protrusion 421 and the limit recess 431 makes the installation of the bracket 420 and the control board 430 more convenient, reduces the alignment difficulty during the installation process, and improves the assembly efficiency.

[0046] Please refer to Figure 2 , Figure 3 and Figure 4 , in some of the embodiments, the ultra-quiet and ultra-thin fan 20 further includes a top cover 600. The top cover 600 covers the base 100 and is located on the side of the fan 300 facing away from the base 100. An air outlet 610 is formed on the top cover 600, and an air inlet 120 is provided on the base 100. The air outlet 610 on the top cover 600 and the air inlet 120 on the base 100 form an effective air flow path, ensuring that air can smoothly pass through the ultra-quiet and ultra-thin fan 20 and improving the heat dissipation efficiency. The combined design of the top cover 600 and the base 100 improves the overall structural strength of the ultra-quiet and ultra-thin fan 20, enhancing the durability and reliability of the device.

[0047] Specifically, in some of the embodiments, the cross-sectional profile of the air outlet 610 is smaller than the cross-sectional profile of the impeller 330. The cross-sectional profile of the air outlet 610 being smaller than the cross-sectional profile of the impeller 330 means that even if the impeller 330 comes off, it cannot escape from the air outlet 610 of the top cover 600, playing a role in limiting and protecting.

[0048] Please refer to Figure 4 , in some of the embodiments, the base 100 is provided with a first clamping member 131, and the top cover 600 is provided with a second clamping member 622. The top cover 600 is clamped to the base 100 through the cooperation of the first clamping member 131 and the second clamping member 622. Through the design of the clamping members, the installation and disassembly of the top cover 600 and the base 100 become more convenient, without the need for additional tools, greatly simplifying the operation steps.

[0049] Further, in some of these embodiments, the wear-resistant member 200 can be in the form of a sheet.

[0050] Further, in some of these embodiments, the wear-resistant member 200 can include, but is not limited to, Mylar sheets.

[0051] Further, in some of these embodiments, the ultra-quiet and ultra-thin fan 20 can also include a label 700 attached to the base 100, and the label 700 can identify the part number code, which is convenient for distinguishing models.

[0052] Further, in some of these embodiments, precise calculations can be performed on the blade structure on the outer periphery of the impeller 330 of the fan 300 and the air duct can be optimized to improve the air pressure and air volume, so that efficient heat exchange can be achieved even in the ultra-thin form.

[0053] Further, in some of these embodiments, the electronic terminal device further includes a temperature sensor disposed in the host 10. The temperature sensor can monitor the temperature change inside the host 10 in real time, provide accurate temperature data, and help to timely understand the operating condition of the device. Combining the data of the temperature sensor, the electronic terminal device can achieve intelligent heat dissipation control, adjust the rotation speed of the fan 300 or other heat dissipation measures according to the actual temperature, ensure that the device operates within the optimal temperature range, improve performance stability, and avoid performance degradation or failure caused by overheating. For example, intelligent chip control can be developed to intelligently adjust the rotation speed of the fan 300 according to the load and surface temperature of the mobile phone CPU, balance heat dissipation and energy consumption, and extend the usage time of the mobile phone. The temperature sensor can issue an alarm or automatically take cooling measures when the device temperature is too high, prevent the device from overheating, protect internal components, and extend the service life of the device. Through the data of the temperature sensor, the device can reduce the rotation speed of the fan 300 or turn off some of the ultra-quiet and ultra-thin fans 20 when the temperature is low, thereby reducing energy consumption and achieving an energy-saving effect.

[0054] Further, in some of these embodiments, the electronic terminal device further includes a circuit board and a battery disposed in the host 10. The heat generated during the operation of the circuit board and the battery can be timely conducted and dissipated through the ultra-quiet and ultra-thin fan 20, thereby ensuring that the device operates within the optimal temperature range.

[0055] Furthermore, in some of these embodiments, a fixing slot 11 is provided inside the host 10, and the ultra-quiet and ultra-thin fan 20 is disposed within the fixing slot 11. The fixing slot 11 can stably fix the ultra-quiet and ultra-thin fan 20, preventing its position deviation caused by vibration or movement during the operation of the device, ensuring that the ultra-quiet and ultra-thin fan 20 is always in the optimal working position. The design of the fixing slot 11 simplifies the installation and maintenance process of the ultra-quiet and ultra-thin fan 20. The user only needs to insert the ultra-quiet and ultra-thin fan 20 into the fixing slot 11, which is convenient and fast, reducing the operation difficulty. The fixing slot 11 can ensure that the ultra-quiet and ultra-thin fan 20 is in close contact with heat sources (such as circuit boards, batteries, etc.), improving the heat conduction efficiency, thereby enhancing the overall heat dissipation effect and preventing the device from overheating.
