Abstract
Description
Technical Field
[0001] The present invention relates to a high-pressure resistant fan with a reinforced structure, and in particular to a high-pressure resistant fan with a reinforced structure applied in the technical field of fans. Background Art
[0002] Under high-pressure and high-speed airflow conditions, fans in the prior art often face greater air resistance and friction, which leads to increased energy loss and reduced fan efficiency. At the same time, the fan blades are prone to wear or imbalance due to long-term operation, which in turn affects the overall performance and service life of the fan. Therefore, how to improve the efficiency of the fan under high-pressure environment, reduce wear and extend the service life has become an important technical challenge.
[0003] Chinese patent CN111412183B discloses a design of a fan impeller, which improves the fixing effect of the blade by adopting a specific concave-convex structure between the fixed end of the blade and the fixing plate, thereby enhancing the stability of the blade, ensuring smooth air discharge of the fan, and increasing the strength of the blade by welding reinforcing ribs. This design improves the performance of the fan blade to a certain extent. However, although the patent improves the stability of the blade through structures such as reinforcing ribs, the blade may still suffer from wear or imbalance problems during high-speed rotation and long-term use, and the worn parts cannot be effectively repaired. At the same time, the patent only optimizes the mechanical structure of the blade, and does not make further improvements to the airflow optimization design and intelligent monitoring technology under high-pressure environments.
[0004] Chinese patent CN111894900B discloses a fan blade design with a reinforced portion. The patent reduces airflow separation and flow loss by setting a curved reinforcement portion on the leading edge of the blade body, thereby improving the efficiency of the fan. Although this design effectively reduces the airflow turning angle and the airflow separation at the root of the fan blade, and solves the energy loss problem caused by the traditional reinforcement rib design, the design of its reinforcement structure is still static and cannot cope with the blade wear and deformation problems caused by long-term operation. In addition, the patent also fails to provide functions on how to monitor the blade status and actively adjust the dynamic balance during the operation of the fan.
[0005] The above two patents improve the performance of fan blades through different designs, and improve the operating efficiency of the fan through mechanical reinforcement structure and airflow optimization respectively, but they still have the following limitations: The wear problem is not solved: As time goes by, the wear of the blades will gradually increase, resulting in a decrease in performance, and the existing patents lack a self-repair mechanism for wear.
[0006] Lack of intelligence: The current design lacks real-time monitoring and automatic adjustment functions, and is unable to make intelligent adjustments based on the stress state of the blades during the operation of the fan, thereby maintaining the stable operation of the fan. Summary of the invention
[0007] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is how to enable the fan to operate efficiently in a high-pressure environment by strengthening the structure, and to improve the service life and operating stability of the fan through intelligent monitoring and self-repair functions.
[0008] In order to solve the above problems, the present invention provides a high-pressure resistant fan with a reinforced structure, comprising a controller and a shell, an impeller is arranged in the shell, a laser assembly is fixedly connected to the top of the shell, the impeller comprises a plurality of blades, the plurality of blades each comprises a frame, a symmetrically arranged functional board is fixedly connected in the frame, the functional board comprises a scale layer, a substrate, a fiber Bragg grating and a partition one are fixedly connected to the bottom end of the scale layer in sequence, an electrostrictive plate is slidably connected to the bottom end of the partition one, and a partition two is slidably connected to the bottom end of the electrostrictive plate, the substrate, the fiber Bragg grating, the partition one and the partition two are all fixedly connected to the frame, the scale layer is composed of a plurality of scales arranged in sequence, the scales are a tip structure away from one end of the shell, micropores are opened at positions corresponding to the tips of the scales on the substrate, the fiber Bragg grating, the partition one, the electrostrictive plate and the partition two, and the corresponding micropores on the substrate, the fiber Bragg grating, the partition one, the electrostrictive plate and the partition two are interconnected, a solution chamber is formed between the symmetrically arranged functional board and the frame, and the solution chamber is filled with photosensitive resin, and the fiber Bragg grating and the electrostrictive plate are both electrically connected to the controller.
[0009] In the above-mentioned high-pressure resistant fan with a reinforced structure, a scale layer imitating a shark scale structure is designed on the blade, which effectively improves the efficiency of the fan by reducing the friction and air resistance between the airflow and the blade, especially maintaining efficient gas flow under high-pressure environment. A fiber Bragg grating is arranged in the fan blade for real-time monitoring of the stress and strain of the blade. The controller can automatically control the electrostrictive plate to adjust according to the monitoring data to ensure that the blade maintains dynamic balance during high-pressure operation and avoid vibration and wear caused by imbalance. The automatic repair of the blade scale layer is realized through the cooperation of the optical fiber monitoring system and the photosensitive resin. When the fiber Bragg grating detects that the blade wear reaches the threshold, the controller will start the repair program, and the electrostrictive plate will release the photosensitive resin to the scale surface. Then the laser component will solidify the resin to repair the worn scale layer to ensure the stability of the fan in long-term use. The present invention is particularly suitable for fan systems in high-pressure environments. Its efficient airflow management and intelligent self-repairing functions ensure that the fan can maintain a good working state under long-term and high-pressure conditions.

[0017] A high pressure resistant fan with a reinforced structure, and a method of using the fan comprises the following steps;
[0018] S1: Connect the pulley on the power shaft to the external power system, start the power system, rotate the power shaft and drive the impeller shaft and multiple blades to rotate, and the gas is thrown out from the blades by centrifugal force;
[0019] S2: During the rotation of the blades, the scale layer reduces air resistance and friction between the scale layer and the gas by imitating the shark scale structure, thereby improving the efficiency of the fan;

[0021] S4: If it is detected that there is a dynamic balance deviation between multiple blades, the controller controls the electrostrictive plate to deform according to the monitoring data to adjust the balance state of the blades to ensure the stable operation of the fan;
[0022] S5: During the long-term use of the fan, if the fiber Bragg grating detects that the stress or strain of the functional board reaches the set threshold, indicating that the scale layer is worn, the controller starts the self-repair program;
[0023] S6: The controller controls the electrostrictive plate to deform so that the photosensitive resin in the solution chamber flows to the surface of the scale layer;
[0024] S7: The laser head in the laser assembly emits laser to solidify the outflowing photosensitive resin to form a new scale layer, thereby repairing the worn parts and restoring the normal function of the fan.
[0025] As another improvement of the present application, the shell includes a liner and an outer shell that match each other, and the outer shell is sleeved on the outer side of the liner, and there is a water cooling cavity between the liner and the outer shell, and a pair of water circulation interfaces are fixedly connected to the outer wall of the outer shell, and the two water circulation interfaces are respectively located at the upper and lower ends of the outer shell;
[0026] The two ends of the shell are respectively connected with a front cover plate and a rear cover, and sealing members are respectively fixedly connected between the shell and the front cover plate and the rear cover.
[0027] In summary, this application has the following beneficial effects:
[0028] 1. High efficiency of gas flow. The fan in this patent has an optimized impeller and blade design, especially the scale layer on the blade imitates the shark scale structure, which effectively reduces the friction between the air and the blade. Through bionic design, the fan significantly reduces air resistance during high-speed operation, improves the efficiency of the fan, and reduces energy loss. The exhaust pipe adopts an elliptical cross-section design, which further reduces the vortex and back pressure problems in the exhaust process, ensuring the smoothness and efficiency of the gas flow.
[0029] 2. Automatic adjustment of dynamic balance. During the operation of the fan, the stress and strain of the functional board are monitored in real time through the fiber Bragg grating. The controller can determine whether there is a dynamic balance deviation in the blade based on the monitored data. Once an imbalance occurs, the controller can deform the electrostrictive plate and automatically adjust the balance state of the blade to ensure that the fan remains stable at high speed and avoid vibration and additional wear caused by imbalance. This dynamic balance automatic adjustment mechanism greatly improves the operating stability and reliability of the fan.
[0030] 3. The self-repair function extends the life of the equipment. During the long-term use of the fan of this patent, the scale layer on the blades may be degraded due to friction and wear. Through real-time monitoring of the fiber Bragg grating, when it is detected that the wear of the scale layer reaches the threshold, the controller can automatically start the self-repair program, and the electrostrictive plate will deform, so that the photosensitive resin is transported to the surface of the scale layer through the hollow impeller shaft and the power shaft. Under the laser irradiation of the laser component, the photosensitive resin is quickly cured to repair the damaged scale structure. This self-repair function reduces the frequency of manual maintenance, extends the service life of the fan, and ensures that the equipment can operate stably for a long time in harsh environments.
[0031] 4. Durability under high pressure environment. The overall structural design of the fan enables it to work under high pressure environment without losing efficiency. The shell structure is solid and the airflow is efficiently managed through the internal impeller and blade system. The existence of the self-healing function further enhances the durability of the fan under high pressure environment. Even during long-term operation, the fan can still maintain efficient operation.
[0032] 5. Automated and intelligent operation. This patented fan has highly intelligent operation capabilities and can automatically adjust and repair according to real-time monitoring data, reducing the need for manual intervention. During operation, the fan can automatically control the electrostrictive plate through the controller to perform dynamic balancing adjustment and automatically start the repair program when wear is detected. This highly automated design improves operating efficiency and reduces operating costs.
[0033] 6. Reduce maintenance costs and downtime. Since the fan has self-monitoring and self-repair functions, wear problems can be automatically solved during operation, reducing the frequency of shutdown for maintenance. This function not only improves the working continuity of the fan, but also reduces maintenance costs and downtime, further improving the economic benefits and use value of the equipment.

[0050] Three embodiments of the present application are described in detail below with reference to the accompanying drawings.
[0051] Example 1
[0052] like Figures 1 to 12As shown, this embodiment relates to a high-pressure resistant blower with a reinforced structure, and its overall structural design is mainly used to handle gas flow under high-pressure environment, especially when long-term operation is required, it has high pressure resistance and airflow efficiency.
[0053] The main components of the fan include a controller, a housing 1, an impeller 2, blades 4 and related functional panels 6, etc.
[0054] Shell 1 and impeller 2, shell 1 is the outer shell of the fan, used to support the internal impeller 2 and other components, the top of the shell 1 is fixedly connected to a laser component 3, which is used for special functions in subsequent embodiments, the two ends of the shell 1 are respectively fixed with a front cover plate 15 and an air intake cover 16, and the part of the air intake cover 16 close to the impeller shaft 14 is provided with multiple air intake holes to ensure that the gas can smoothly enter the inside of the fan.
[0055] The impeller 2 and the blades 4 are installed in the housing 1. The impeller 2 is composed of a plurality of blades 4. Each blade 4 includes a frame 5. A symmetrically arranged functional plate 6 is fixedly connected inside the frame 5. One end of the blade 4 is fixedly connected to the same impeller shaft 14. The impeller shaft 14 is a hollow cylindrical structure, and its interior is connected to the solution chamber between the functional plates 6 to ensure the flow of liquid between the impeller and the functional plates.
[0056] The impeller shaft 14 and the power shaft 17 are rotatably connected with each other through the front cover plate 15. One end of the power shaft 17 close to the impeller shaft 14 is fixedly connected to the front cover plate 15. The power shaft 17 drives the impeller shaft 14 to rotate through an external power system, thereby driving the blades 4 to rotate, generating centrifugal force to throw the gas out.
[0057] The exhaust pipe design is that the outer end of the shell 1 is fixedly connected with an exhaust pipe with an elliptical cross-section for smoothly discharging the gas. The exhaust pipe with an elliptical structure can optimize the airflow discharge effect and reduce the airflow resistance, which is suitable for long-term operation of the high-pressure fan in a complex environment.
[0058] Working process:
[0059] The gas enters and moves. Driven by the external power system, the power shaft 17 drives the impeller shaft 14 to rotate through the pulley, and the multiple blades 4 on the impeller 2 rotate accordingly, generating centrifugal force, causing the gas to enter from the air inlet. The gas is accelerated by the blades 4 and discharged outward.
[0060] The scale layer bionic design, during the operation of the fan, the scale layer 7 arranged on the blade 4 reduces the friction between the air and the blade surface by imitating the structure of shark scales. This design greatly reduces the air resistance and improves the working efficiency of the fan, especially under high-speed rotation, it can effectively reduce energy consumption.
[0061] The airflow is discharged through the centrifugal force generated by the rotation of the fan, and the gas is rapidly accelerated and discharged from the exhaust pipe. The exhaust pipe structure with an elliptical cross-section not only optimizes the discharge path of the airflow, but also reduces the possibility of vortex formation, further improving the exhaust efficiency of the fan.
[0062] The high efficiency of gas flow, the design of the impeller 2 and the blades 4 enables the gas to be effectively accelerated and discharged through centrifugal force under high pressure environment, and the multiple air inlet holes on the air inlet cover 16 ensure that the gas can smoothly enter the fan and generate continuous airflow through the rotation of the impeller shaft 14.
[0063] The bionic drag-reducing effect of the scale layer: the scale layer 7 on the blade 4 effectively reduces the friction of the airflow on the blade surface through bionic design, and the tip structure of the scale 13 reduces the turbulence and resistance in the gas flow, which enables the fan to operate with lower energy consumption under high pressure and high speed conditions.
[0064] The pressure resistance of the shell design. The design of shell 1 takes into account the airflow distribution and pressure management in a high-pressure environment. In particular, the elliptical cross-section of the exhaust pipe helps to reduce back pressure during the exhaust process and ensure smoother gas discharge. This design significantly improves the overall work efficiency of high-pressure fans that run for a long time.
[0065] The stability of the structure, the rotational connection between the impeller shaft 14 and the front cover plate 15 and the air intake cover 16 ensures the stability of the impeller system, can maintain the dynamic balance of the system during high-speed rotation, and effectively reduces the possibility of vibration and wear.
[0066] Through the description of the above structure and working process, this embodiment demonstrates a high-pressure resistant fan that can operate efficiently in a high-pressure environment, which effectively improves the gas flow efficiency and stability of the fan through the bionic scale layer design, impeller and exhaust system optimization.
[0067] Example 2
[0068] like Figures 1 to 12 As shown, this embodiment is based on the embodiment 1, and focuses on demonstrating the intelligent monitoring and self-repair functions of the wind turbine under high pressure environment. Through the synergistic effect of the laser assembly 3, the fiber Bragg grating 9, the electrostrictive plate 11 and other components, the wind turbine can detect and self-repair in real time when the blade 4 is worn, thereby extending the service life of the equipment.
[0069] The power shaft 17 and the liquid supply system. The power shaft 17 is a hollow structure. The end away from the impeller shaft 14 passes through the front cover 15. The outer end of the passing part is fixedly connected to a pulley, which can drive the impeller shaft 14 to rotate through an external power system. The hollow part of the power shaft 17 is connected to the hollow part of the impeller shaft 14 and is connected to the external liquid supply system. This design ensures that during the operation of the fan, the photosensitive resin in the solution chamber can be transported to the scale layer 7 through the power shaft 17 and the impeller shaft 14 when needed, thereby realizing the self-repair function.
[0070] The laser component 3 and the laser head 18 are fixedly connected to the top of the shell 1. A multi-angle adjustable laser head 18 is fixed inside the laser component 3. The laser head 18 can project laser and accurately irradiate each scale 13 on the scale layer 7. The laser head 18 can adjust the angle through the controller as needed to ensure that the laser can cover all scale areas. A light-transmitting partition is fixedly connected to the shell of the laser component 3. The light-transmitting partition ensures that the laser can pass through and irradiate the scale layer 7 without being disturbed by the external environment.
[0071] The working principle of the self-repairing system is that when the scale layer 7 on the blade 4 is worn due to long-term use, the fiber Bragg grating 9 will monitor the stress and strain changes of the functional board 6 in real time. These monitoring data will be transmitted to the controller. When the stress or strain reaches the set threshold, the controller will start the self-repairing program. At this time, the controller will deform the electrostrictive plate 11, so that the photosensitive resin in the solution chamber is transported to the surface of the scale layer 7 through the hollow impeller shaft 14 and the power shaft 17.
[0072] During the laser curing process, after the photosensitive resin flows to the surface of the scale layer 7, the laser head 18 in the laser assembly 3 starts working. The laser head 18 emits a laser and accurately irradiates the scale 13. Through laser irradiation, the photosensitive resin is quickly cured to form a new scale structure, thereby repairing the worn part of the scale layer 7. After the repair is completed, the fan can continue to work normally under high pressure.
[0073] Working process:
[0074] During startup and operation, driven by an external power system, the power shaft 17 drives the impeller shaft 14 and the blades 4 to rotate through a pulley, generating centrifugal force to throw the gas out of the fan to achieve efficient gas flow. At the same time, the fiber Bragg grating 9 monitors the stress and strain state of the functional plate 6 on the blade 4 in real time.
[0075] Real-time monitoring and repair are started. As the fan runs for a long time, the scale layer 7 may experience stress concentration due to wear. After the fiber Bragg grating 9 detects this change, the data is transmitted to the controller. If the stress exceeds the threshold, the controller will start the self-repair program, activate the electrostrictive plate 11 to deform it, and then transport the photosensitive resin to the scale layer 7 through the hollow structure of the power shaft 17 and the impeller shaft 14.
[0076] After laser curing and repair are completed, the photosensitive resin flows to the scale layer 7, and the laser head 18 in the laser assembly 3 is precisely aligned with the scale 13 through multi-angle adjustment, and the laser is emitted for curing. The photosensitive resin quickly forms new scales under the laser irradiation, completing the repair process. After the repair is completed, the fan continues to operate stably under high pressure.
[0077] Intelligent monitoring and repair function, through real-time monitoring of the fiber Bragg grating 9, the fan can grasp the status of the blade 4 at any time, and can automatically trigger the self-repair program when the scale layer 7 is worn. This function effectively reduces the need for manual maintenance and extends the service life of the fan.
[0078] Precise laser curing, the multi-angle adjustable design of the laser head 18 ensures that the laser can accurately irradiate each scale 13. Regardless of the position of the scale, the laser head can adjust the angle for effective repair. The setting of the light-transmitting partition avoids the interference of external light on the laser curing process, ensuring the accuracy and reliability of the repair.
[0079] Efficient liquid transmission, the hollow structure of the power shaft 17 and the impeller shaft 14, and the connection design with the external liquid supply system enable the photosensitive resin to be efficiently transmitted to the scale layer 7. When repair is needed, the resin flow channel is unobstructed, ensuring the timeliness of the repair.
[0080] Self-repair extends service life. The fan's self-repair system can automatically repair worn scales during fan operation, thereby significantly reducing performance degradation caused by wear. This mechanism ensures that the fan can operate stably for a long time under high-pressure environments, improving the overall reliability and durability of the equipment.
[0081] This embodiment greatly improves the adaptability and service life of the high-pressure resistant fan in high-pressure and complex environments by combining an intelligent monitoring system, laser repair technology, and the self-repair function of photosensitive resin.
[0082] Example 3
[0083] like Figures 1 to 12As shown, this embodiment is based on Embodiment 1 and Embodiment 2, and describes in detail a method for using a high-pressure resistant fan with a reinforced structure, focusing on the overall operation process of the fan, the air flow principle, the dynamic balance adjustment mechanism, and the self-repair function. Through the detailed description of each step, the intelligent monitoring and repair operation process of the fan during use can be clearly understood.
[0084] Fan start-up and gas flow
[0085] S1: Connect the pulley on the power shaft 17 to the external power system, start the external power system, and the power shaft 17 starts to rotate, driving the impeller shaft 14 and multiple blades 4 to rotate. During the rotation of the impeller 2, the blades 4 use centrifugal force to throw the gas out from the central area of the impeller, forming a strong airflow.
[0086] S2: During the rotation of the blade 4, the scale layer 7 on the blade reduces the resistance of the airflow to the blade surface and the friction between the gas and the scale layer 7 by imitating the structure of shark scales. Through this bionic design, the airflow flows more smoothly, thereby improving the efficiency of the fan and reducing energy loss.
[0087] Intelligent monitoring and dynamic balancing adjustment
[0088] S3: During the operation of the wind turbine, the stress and strain state of the functional board 6 is monitored in real time through the fiber Bragg grating 9 in the blade 4. The monitoring data will be continuously transmitted to the controller, and the controller can analyze the operating state of the wind turbine in real time according to the changes in stress and strain.
[0089] S4: If the controller detects that there is a dynamic balance deviation between the multiple blades 4 (for example, the blades are unbalanced due to wear or structural deformation), the controller will control the electrostrictive plate 11 to deform to adjust the dynamic balance state of the blades 4. This function ensures the stability of the fan during high-speed rotation and reduces vibration and wear caused by blade imbalance.
[0090] Self-healing process
[0091] S5: During long-term use of the fan, the scale layer 7 may become thinner or damaged due to friction and wear. The fiber Bragg grating 9 will continuously monitor the stress and strain state of the functional board 6. Once the set threshold is reached, indicating that the scale layer 7 is severely worn, the controller will start the self-repair program.
[0092] S6: The controller activates the electrostrictive plate 11 to deform it, so that the photosensitive resin in the solution chamber flows to the surface of the scale layer 7 through the hollow impeller shaft 14 and the power shaft 17. The photosensitive resin forms a covering on the scale surface, waiting for further processing.
[0093] S7: When the photosensitive resin flows to the surface of the scale layer 7, the laser head 18 in the laser assembly 3 will start working. The laser head 18 emits laser light onto the scale 13 through precise positioning and multi-angle adjustment. The photosensitive resin quickly solidifies under the irradiation of the laser to form a new scale layer, thereby completing the repair of the worn scale.
[0094] Working process:
[0095] Starting and running of the fan: The fan is started by an external power system, and the power shaft 17 drives the impeller shaft 14 and the blades 4 to rotate. The gas is thrown out by the blades to form a high-pressure airflow. The bionic structure of the scale layer 7 reduces the gas resistance, allowing the fan to operate more efficiently.
[0096] Intelligent monitoring and balance adjustment: The stress and strain of the blades 4 are monitored in real time through the fiber Bragg grating 9. When the fan is running, it can detect whether the blades are in a dynamic balance state. If there is an imbalance between the blades, the electrostrictive plate 11 will deform according to the monitoring data, adjust the balance of the blades, and ensure the smooth operation of the fan.
[0097] Self-repair process: During long-term use, when the scale layer 7 is worn to a certain extent, the fiber Bragg grating 9 will sound an alarm, the controller will start the self-repair program, the photosensitive resin will flow to the scale surface through the liquid delivery system, and the laser head 18 will emit laser to cure the photosensitive resin, forming new scales and restoring the performance of the blade.
[0098] High-efficiency airflow control and bionic design improve efficiency. The scale layer 7 imitates the design of shark scales, effectively reducing the friction between the airflow and the blades 4. This bionic structure enables the fan to reduce resistance when rotating at high speed, thereby improving gas flow efficiency and reducing energy loss.
[0099] Intelligent monitoring and dynamic balancing ensure operational stability. Through the real-time monitoring of the fiber Bragg grating 9 and the balancing adjustment function of the electrostrictive plate 11, the fan can maintain dynamic balance during high-speed operation to avoid vibration and wear of the blades 4 caused by imbalance. This function ensures the stable operation of the fan and effectively extends the service life of the equipment.
[0100] The self-repair function extends the service life of the equipment. When the scale layer 7 is worn, the controller can automatically trigger the repair program. The electrostrictive plate 11 works together with the laser component 3 to achieve self-repair of the scale 13 through photosensitive resin and laser curing. This self-repair function reduces maintenance costs and significantly extends the service life of the equipment.
[0101] Intelligence and automation improve operational efficiency. The overall design of the fan combines intelligent monitoring and self-repair technology, reducing the need for manual intervention. The fan can automatically adjust and repair according to real-time data, greatly improving the automation level and operating efficiency of the equipment.

[0104] like Figure 13-14 As shown, this embodiment is based on the embodiment 1, and focuses on showing the heat dissipation structure of the fan. The shell 1 includes a liner 101 and an outer shell 102 that match each other, and the outer shell 102 is sleeved on the outer side of the liner 101. There is a water cooling cavity 103 between the liner 101 and the outer shell 102. A pair of water circulation interfaces 104 are fixedly connected to the outer wall of the outer shell 102. The two water circulation interfaces 104 are respectively located at the upper and lower ends of the outer shell 102, and the two water circulation interfaces 104 both penetrate the outer shell 102 and connect the water cooling cavity 103 with the outside. Cooling water can be exchanged through the two water circulation interfaces 104, and the water circulation interface 104 located on the lower side is a water inlet, and the water circulation interface 104 located on the upper side is a water outlet;
[0105] The two ends of the housing 1 are respectively connected with a front cover plate 15 and a rear cover 19 , and sealing members 20 are respectively fixedly connected between the housing 1 and the front cover plate 15 and the rear cover 19 .
[0106] In particular, in the drawings of the specification of the present application, for the convenience of display, the various structures are not drawn strictly according to the proportions. Those skilled in the art can reasonably design the dimensions of each structure according to actual needs. This is a common technology among those skilled in the art, and therefore is not disclosed in detail in the present application.
[0107] Compared with embodiments 1-3, a water cooling structure is added to the fan in this embodiment to dissipate heat from the fan, thereby preventing the fan from operating in a continuously high temperature environment, making the fan structure less prone to premature aging and effectively maintaining the service life of the fan.
[0108] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
