Description

Technical Field

[0001] This invention relates to the field of heat dissipation technology for jet looms, specifically to a cooling fan structure for an electric motor based on jet spinning. Background Technology

[0002] Air-jet spinning machines, as core equipment in the modern textile industry for large-scale yarn production, can efficiently process various fiber raw materials to produce yarns that meet the needs of different fields, widely serving the production processes of industries such as apparel, home textiles, and industrial textiles. During continuous operation, fibers are prone to breakage and shedding in the processing flow, generating a large amount of fly filth. This fly filth remains suspended in the workshop environment, forming continuous dust pollution and becoming a significant factor affecting the stable operation of the equipment.

[0003] In the transmission system of an air-jet spinning machine, the sixteen heald frame motors play a crucial role in controlling the movement of the heald frames and ensuring the precise weaving of the fabric. Their operating status directly affects the efficiency of textile production and the quality of the fabric. To ensure that the heald frame motors maintain a suitable operating temperature under long-term high-load operation, each heald frame motor is equipped with an independent cooling fan. This fan removes the heat generated by the motor through forced air cooling, maintaining the motor's normal operating condition. However, due to the continuous presence of fly ash in the workshop, the cooling fans become a major area for fly ash accumulation during operation. The fans themselves and surrounding components are easily covered with fly ash. At the same time, when the fans draw in air as a cooling medium, they also draw in air containing fly ash and deliver it to the heat dissipation channels inside the motor. This results in the cooling medium always containing fly ash impurities, failing to provide a clean heat dissipation environment for the motor. Meanwhile, fly shavings and impurities in the cooling medium can cause a series of chain problems: on the one hand, a large amount of fly shavings will adhere to the surface of the cooling fan blades, the protective cover, and the inner wall of the air intake channel. As the running time increases, the amount of fly shavings will gradually increase. These fly shavings will also get tangled on the bearing assembly of the motor shaft, interfering with the normal operation of the bearing. On the other hand, fly shavings attached to the fan will enter the equipment with the airflow, which will compress the effective ventilation space and significantly increase the ventilation resistance. This will lead to a significant decrease in the fan's heat dissipation capacity, making it unable to remove the heat generated by the motor in time and hindering the heat inside the motor from being discharged to the outside.

[0004] In summary, existing cooling fan structures for motors in air-jet spinning machines fail to effectively clean the cooling medium containing fly ash. This leads to the continuous accumulation of fly ash within the fan and motor cooling system, causing a series of problems such as decreased cooling efficiency, frequent motor failures, production quality fluctuations, and safety hazards. This has become a key bottleneck restricting the stable, efficient, and safe operation of air-jet spinning machines. Therefore, developing a cooling fan structure capable of cleaning the cooling medium of air-jet spinning machines and preventing fly ash from adversely affecting the cooling fan and motor cooling system is an extremely urgent practical need and has significant industry application value.

[0005] Therefore, this invention proposes a cooling fan structure for an electric motor based on jet spinning to solve the above problems. Summary of the Invention

[0006] In view of this, the technical problem to be solved by the present invention is to propose a cooling fan structure for an electric motor based on jet spinning, so as to solve the problems existing in the prior art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a cooling fan structure for an electric motor based on jet spinning, comprising: a loom body, and further comprising: a first component; The first component includes a main frame, with magnets symmetrically fixedly connected to the four corners of the bottom surface of the main frame, and the main frame is magnetically fixedly connected to the loom body by the magnets; The bottom of the main frame is fitted and fixedly connected to a labyrinth filter plate. A second airflow hole is opened through the upper surface of the labyrinth filter plate. The labyrinth filter plate has a side wall cavity and an inner cavity. A labyrinth ring is fixedly connected to the inner cavity of the labyrinth filter plate. Diversion holes are opened through the labyrinth ring at intervals. The labyrinth filter plate has a third airflow hole through its lower surface, and an airflow connection groove is formed on the bottom surface of the labyrinth filter plate.

[0008] Preferably, a second component is also included; The second component includes recessed grooves symmetrically formed on the inner wall of the main frame, and a barrier tile plate is slidably connected in the recessed groove; The barrier tile plate is composed of a concave surface and a convex surface, and the convex surface of the barrier tile plate is provided with first airflow holes that are equidistantly opened; A cam is fixedly connected to the recessed groove via a motor, and the cam is symmetrically arranged on both sides of the barrier tile plate.

[0009] Preferably, the outer ring surface of the cam is fixedly connected with convex columns at equal intervals, and the vertical sidewall of the recessed groove is fixedly connected with semi-cylinders at equal intervals.

[0010] As a preferred option, a third component is also included; The third component includes V-shaped grooves equidistantly formed on the barrier tile plate, i.e., the recessed surface of the barrier tile plate; and transfer openings equidistantly formed through the barrier tile plate. The labyrinthine filter plate is symmetrically fixedly connected to two ends with a collection box. The collection box has a storage opening that is equidistantly through it, and a pull-out compartment is slidably connected inside the collection box.

[0011] Preferably, a driving device is fixedly connected inside the side wall cavity of the labyrinth filter plate, the side wall of the labyrinth filter plate is provided with a strip-shaped annular groove, the driving device consists of two driving gears and a belt, and an external connecting part is fixedly connected to the belt of the driving device; A spring telescopic strip is rotatably connected to the external connector, and a cleaning strip is slidably connected to the top of the spring telescopic strip.

[0012] Preferably, the opening range of the second airflow hole coincides vertically with the shape of the labyrinth ring.

[0013] Preferably, the range of the third airflow hole is opposite to the range of the second airflow hole, that is, the range through which the third airflow hole is opened does not coincide with the shape of the labyrinth ring.

[0014] Preferably, the stabilizing block consists of a square cavity and five spheres.

[0015] Compared with the prior art, the present invention provides a cooling fan structure for an electric motor based on air-jet spinning, which has the following beneficial effects: 1. In the cooling fan structure for an electric motor based on air-jet spinning, the labyrinth ring included in the first component of the present invention, with its surrounding structure design, can bring the following benefits in the process of dealing with the interference of fly ash on the cooling system in the air-jet spinning workshop: It significantly reduces the amount of fly ash adhering to the cooling fan and ensures the long-term stable operation of the fan: The labyrinth ring creates key conditions for the interception and retention of fly ash by extending the path length and time for small fly ash to move to the cooling fan; On the one hand, the longer channel design makes the small fly ash that originally rushed to the fan with the airflow need to pass through the complex passage of the labyrinth ring. As the airflow travels through the channel for a longer period, its velocity gradually decreases due to the extended path, reducing the kinetic energy of the fly debris and making it difficult for it to maintain high speed towards the fan blades. On the other hand, the rough sidewalls of the air duct provide ample surface for the fly debris to adhere to. The fly debris, with its reduced kinetic energy, will gradually attach to the sidewalls under the influence of the airflow, rather than continuing to enter the fan area with the airflow. This process significantly reduces the number of tiny fly debris that ultimately reaches the cooling fan, reducing the amount of fly debris accumulating on the fan blades and protective cover from the source. It avoids problems such as uneven blade weight and increased ventilation resistance caused by fly debris, ensuring that the fan always operates stably and reducing the risk of motor cooling interruption due to fan failure. In summary, the labyrinth ring design is not merely a structural supplement, but a core solution to the problem of fly debris interference in the cooling system of jet textile motors. Through its "delay-adsorption-interception" effect on fly debris, it provides superior performance to the cooling fan structure of jet textile motors from four key dimensions: ensuring fan operation, stabilizing cooling efficiency, reducing maintenance costs, and improving safety. This effectively overcomes the bottlenecks of traditional structures and helps jet textile machines achieve long-term stable, efficient, and safe operation.

[0016] 2. In the cooling fan structure for the motor based on jet spinning in this invention, the second component uses a cam as the core driving part. Through the multi-dimensional linkage triggered by the rotation of the cam, a systematic optimization is formed for key aspects such as fly waste collection, component unobstructed flow, and fly waste storage. This further compensates for the shortcomings of traditional structures in fly waste handling and provides stronger protection for the long-term stable operation of the equipment. The specific benefits are as follows: Optimize the waste collection path and improve the efficiency of waste collection: The cam causes the barrier tile to sway left and right on the horizontal plane during rotation. This design creates key conditions for the directional transfer and centralized collection of waste. In the heat dissipation system of the jet textile workshop, the fly ash floating in the air will fall onto the raised surface of the barrier tile with the airflow. If not handled in time, these fly ash will accumulate on the raised surface and gradually affect the normal protective function of the barrier tile. The shaking action driven by the cam can use inertial force to make the fly ash on the raised surface move towards the concave part (i.e., V-groove) of the barrier tile. The structural characteristics of the V-groove can effectively collect the fly ash transferred here, preventing the fly ash from falling randomly on the surface of the barrier tile. The above-mentioned "shaking-transfer-collection" linkage mechanism not only makes the fly ash collection process more directional and regular, but also provides the necessary premise for the subsequent unified cleaning or treatment of fly ash, greatly reducing the amount of fly ash residue on the barrier tile, ensuring that the barrier tile always maintains a good protective and airflow guiding effect, and further reducing the risk of fly ash entering the core area of ​​the cooling fan. To reduce the risk of component blockage and ensure the smooth flow of the heat dissipation system: The cam, through the interaction of the convex column and the semi-cylinder, drives the main frame, the waste collection box, and the pull-out compartment to generate vibration. This vibration can first and foremost address the problem of component blockage. During the collection and transportation of fly waste, due to its lightweight and easily tangled nature, fly waste tends to accumulate in the waste inlet channel of the waste collection box or at the entrance of the pull-out compartment. If the accumulation gradually increases, it can lead to narrowing or even blockage of the channel, affecting the normal falling and collection of fly waste, and consequently causing poor airflow in the subsequent heat dissipation system. The vibration triggered by the cam can be transmitted through the main frame to the key channels of the waste collection box and the pull-out compartment, using vibration to loosen and remove fly waste attached to the transfer port and the collection port, preventing fly waste from forming stubborn accumulation in the channel. The above-mentioned vibration anti-blockage design can maintain the unobstructed flow of the waste collection box and the pull-out compartment without the need for frequent manual disassembly and cleaning, ensuring the continuous operation of the fly waste collection system, indirectly providing support for the stable ventilation of the cooling fan, and avoiding the problem of reduced heat dissipation efficiency due to channel blockage. Compress the storage gap of flying fluffs to improve the storage capacity of the drawer bin: The above-mentioned vibration force triggered by the cam can also play a positive role in optimizing the storage state of flying fluffs in the drawer bin. In the traditional flying fluff storage structure, a large number of gaps will naturally form after the flying fluffs enter the drawer bin, resulting in serious waste of the actual storage space of the drawer bin. Even if the drawer bin appears to be full, there is still a large amount of unused space inside, which requires operators to frequently draw it out for cleaning, increasing the frequency of shutdown maintenance. The vibration force can act on the flying fluffs in the drawer bin, causing the flying fluffs to squeeze against each other during vibration, significantly compressing the originally existing gaps, and significantly increasing the stacking density of the flying fluffs. This change directly increases the storage capacity of flying fluffs per unit volume of the drawer bin, extends the cleaning cycle of the drawer bin, and reduces the number of shutdowns caused by operators replacing or cleaning the drawer bin. At the same time, the compressed flying fluffs are more likely to form a regular stacking shape, avoiding the "bridging" phenomenon of flying fluffs in the drawer bin (that is, the flying fluffs are locally suspended in the bin, and the space below cannot be utilized), further ensuring the stability of the storage function of the drawer bin, and providing a more sufficient buffer space for the continuous production of the equipment; To sum up, the design of the second component with the cam as the core is not a single-function optimization, but through multi-dimensional linkage, it forms a coordinated improvement in flying fluff collection, channel smoothness, storage efficiency and maintenance convenience. Its maze ring with the first component forms a complete flying fluff processing chain of "interception - collection - storage", effectively solving the problems of incomplete flying fluff processing, easy blockage and frequent maintenance in the traditional cooling fan structure, providing more comprehensive and stable performance guarantee for the cooling fan structure of the motor based on air-jet spinning, and helping the air-jet spinning machine to achieve stable operation with higher efficiency and lower faults.

[0017] 3. The present invention adopts a rotational connection method for the scraping strip on the spring telescopic strip, which is a key optimization design for the pain points of "easy to break away and difficult to concentrate" during the transfer of flying fluffs in the V-shaped groove. The rotational connection method, through the synergistic effect with the self-weight and inclined state of the scraping strip, forms an efficient flying fluff processing mechanism with functions of scraping, kneading and preventing breakaway, providing important support for the stability and reliability of the overall flying fluff collection system, and bringing the following benefits: Effectively inhibit the breakaway of flying fluffs and reduce the risk of flying fluff residue and secondary pollution in the V-shaped groove: The flying fluffs in the textile workshop are light in texture. When the traditional scraping structure transfers flying fluffs, if there is a slight air flow fluctuation or the scraping action is unstable, the flying fluffs are easily broken away from the scraping path and scattered or dropped from the V-shaped groove, which not only reduces the flying fluff collection efficiency, but also causes secondary pollution, that is, the broken-away flying fluffs will re-suspend in the air and pose a threat to components such as the cooling fan and the motor again. The inclined state and the self-weight downward pressure brought by the rotational connection solve this problem at the root, effectively reducing the breakaway rate of flying fluffs during the transfer process; To achieve active clumping of fly waste and improve its concentration and controllability: The rotating connection between the cleaning strip and the spring telescopic strip allows the cleaning strip to naturally tilt as it moves within the V-groove. This tilt, combined with the downward pressure generated by the strip's own weight, creates a "clumping effect." During cleaning, the tilted sidewall of the cleaning strip laterally compresses the fly waste scattered within the V-groove, while the downward pressure from its own weight compacts the fly waste towards the bottom of the V-groove. The combined effect of these two factors dissolves the originally loose and fine fly waste. The broken fly shavings are gradually kneaded into compact fly shaving clumps. Compared to traditional scraping structures that can only push fly shavings away, the above-mentioned active kneading design greatly improves the concentration of fly shavings. The fly shaving clumps are larger and heavier, making them less likely to be blown away by airflow. During the subsequent transfer to the waste collection box or pull-out compartment, they are more likely to form a directional and stable movement trajectory, avoiding the fly shavings from being scattered or stuck in the transfer path. This upgrades fly shaving collection from disordered cleaning to orderly collection, significantly improving the controllability of the overall fly shaving treatment system.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0022] Example

[0023] Please refer to Figure 3 , Figure 8 , Figure 9 As shown: To address the problems mentioned in the technical solutions, this application provides a cooling fan structure for an electric motor based on jet spinning, comprising: a loom body 1, and further comprising: a first component 2; The first component 2 includes a main frame 201, with magnets 202 symmetrically fixedly connected to the four corners of the bottom surface of the main frame 201. The main frame 201 is magnetically fixedly connected to the loom body 1 by the magnets 202. A labyrinth filter plate 203 is fitted and fixedly connected to the bottom of the main frame 201. A second airflow hole 204 is opened through the upper surface of the labyrinth filter plate 203. A side wall cavity and an inner cavity are opened on the labyrinth filter plate 203. A labyrinth ring 205 is fixedly connected to the inner cavity of the labyrinth filter plate 203. A diversion hole 206 is opened through the labyrinth ring 205 at intervals. A third airflow hole 207 is opened through the lower surface of the labyrinth filter plate 203. An airflow connection groove 208 is opened on the bottom surface of the labyrinth filter plate 203.

[0024] Among them, the first component 2 is used as the second layer of interception mechanism.

[0025] The main frame 201 is also symmetrically provided with threaded holes; in specific use, it can be installed and used in conjunction with magnet 202 according to specific installation requirements.

[0026] Magnet 202 can help the main frame 201 to be magnetically attracted to the cooling fan protective partition of the loom body 1; thus, the cooling fan blocks impurities (flying flowers) carried in the cooling medium (air), thereby cleaning the cooling medium.

[0027] The opening range of the second airflow circular hole 204 coincides with the shape of the maze ring 205 in the vertical direction; that is, the second airflow circular hole 204 and the maze ring 205 are in an intersecting state.

[0028] A filter is installed on the second airflow hole 204.

[0029] The maze loop 205 can be designed into any geometric line intersection group according to specific use.

[0030] The side walls of maze ring 205 are relatively rough, which may prevent the first layer of fly flower blocking mechanism from blocking the fly flowers from adhering to the inner wall of the maze ring 205 channel.

[0031] The range of the third airflow hole 207 is opposite to the range of the second airflow hole 204, that is, the range through which the third airflow hole 207 is opened does not coincide with the shape of the labyrinth ring 205.

[0032] The airflow connection groove 208 is connected to the third airflow hole 207 to provide a movement channel for airflow.

[0033] A further embodiment: Please refer to Figure 1 , Figure 2 , Figure 4 , Figure 6 As shown: The second component 3 includes recessed grooves 301 symmetrically formed on the inner wall of the main frame 201. A barrier tile plate 302 is slidably connected to the recessed groove 301. The barrier tile plate 302 consists of a concave surface and a convex surface. A first airflow hole 303 is equidistantly formed on the convex surface of the barrier tile plate 302. A cam 304 is fixedly connected to the recessed groove 301 via a motor. The cam 304 is symmetrically arranged on both sides of the barrier tile plate 302. A raised column 305 is fixedly connected to the outer ring surface of the cam 304 at equal intervals. A semi-cylinder 306 is fixedly connected to the vertical side wall of the recessed groove 301 at equal intervals.

[0034] Among them: the second component 3 is used to block the fly shavings from adhering to the main body of the device; to prevent the fly shavings from blocking the first airflow hole 303.

[0035] A filter is installed on the first airflow hole 303.

[0036] Cam 304 is driven by a motor.

[0037] The raised bar 305 is used in conjunction with the semi-cylinder 306. When the cam 304 carries the raised bar 305 past the position of the semi-cylinder 306, the uneven surface of the component will cause the main frame 201, the collection box 403, and the pull-out compartment 405 to vibrate. This vibration can reduce the clogging of the storage opening 404 by fly debris. At the same time, the vibration can reduce the gap of fly debris in the pull-out compartment 405, thereby increasing the storage capacity of fly debris.

[0038] A further embodiment: Please refer to Figures 2 to 7 As shown: The third component 4 includes V-shaped grooves 401 equidistantly formed on the barrier tile plate 302, i.e., the concave surface of the barrier tile plate 302; transfer ports 402 are equidistantly formed through the barrier tile plate 302; a collection box 403 is symmetrically fixedly connected to both ends of the labyrinth filter plate 203, a storage port 404 is equidistantly formed through the collection box 403, a pull-out compartment 405 is slidably connected inside the collection box 403, a drive device 406 is fixedly connected inside the side wall cavity of the labyrinth filter plate 203, a strip-shaped annular groove 407 is formed on the side wall of the labyrinth filter plate 203, the drive device 406 consists of two drive gears and a belt, an external connector 408 is fixedly connected to the belt of the drive device 406; a spring telescopic strip 409 is rotatably connected to the external connector 408, a cleaning strip 410 is slidably connected to the top of the spring telescopic strip 409, and a stabilizing block 411 is symmetrically fixedly connected to the bottom surfaces of both ends of the cleaning strip 410.

[0039] Among them, the third component 4 is used to collect and transfer the fly ash attached to the barrier tile 302.

[0040] The width of the storage opening 404 is greater than the width of the transfer opening 402, so as to ensure that when the blocking tile 302 moves horizontally to the left and right, the scraping strip 410 can be transferred from the transfer opening 402 and enter the pull-out compartment 405 through the storage opening 404.

[0041] The drive unit 406 consists of two drive gears and a belt.

[0042] The strip-shaped annular groove 407 is used to provide guidance for the external connector 408.

[0043] The top of the spring telescopic strip 409 has a through hole.

[0044] The triangular protrusions evenly distributed on the cleaning strip 410 are adapted to the V-shaped grooves 401 on the barrier tile 302.

[0045] The stabilizing block 411 consists of a square cavity and five spheres. When the cleaning blade 410 moves, the spheres in the stabilizing block 411 will roll, thereby assisting the smoothness of the movement of the cleaning blade 410.

[0046] The working principle of all the content in the above embodiments is as follows: It should be noted that the overall device is installed on the external partition of the cooling fan on the main body 1 of the loom; and when the overall device is cleaning the cooling medium, the working states of the second component 3 and the third component 4 are divided into two situations: Scenario 1: When the amount of fly ash in the air is small, the second component 3 works first, and then the third component 4 works; Scenario 2: When the amount of fly ash in the air is large, the second component 3 and the third component 4 work simultaneously to improve efficiency. Since the movement of the working parts of the second component 3 and the third component 4 remains unchanged in the above two situations, only in the second situation will the cleaning strip 410 move back and forth with the blocking tile plate 302 when pushing fly ash, therefore, the following only describes the working state of Scenario 1.

[0047] The following describes the working process of the second component 3 and the third component 4: During use, while the cooling fan is cooling the motor of the device, the flying debris floating in the air will fall onto the barrier tile plate 302. In this process, the cam 304 on the left side of the barrier tile plate 302 will first push the barrier tile plate 302 to the right. Then, as the cam 304 on the right side of the barrier tile plate 302 rotates, the barrier tile plate 302, which was originally moving horizontally to the right in the recessed groove 301, will be pushed to the left. This process repeats. Under the action of the cam 304 driving the barrier tile plate 302 to swing back and forth, the inertial force can be effectively used to make the flying debris on the raised surface of the barrier tile plate 302 move into the recessed part of the barrier tile plate 302, i.e., the V-shaped groove 401. In this way, the flying debris is effectively collected, preventing it from scattering disorderly on the surface of the barrier tile plate 302. Furthermore, once the waste is collected, the second component 3 stops working. At this time, the drive device 406 in the third component 4 will drive the spring telescopic bar 409 to move through the external connector 408. (See attached diagram.) Figure 4 and appendix Figure 7As the external connector 408 is driven by the drive device 406 to move in the strip-shaped annular groove 407, the external connector 408 will move on the barrier tile plate 302 via the spring telescopic strip 409 carrying the cleaning strip 410. With the movement of the cleaning strip 410, the cleaning strip 410 will push and transfer the fly waste temporarily stored and transferred to the V-shaped groove 401; furthermore, with the pushing of the cleaning strip 410, the fly waste originally located in the V-shaped groove 401 will gradually gather together. At this time, the spring telescopic strip 409... The cleaning strip 410 with the rotating connection 09 will gradually tilt. At this time, under the action of its own weight, the cleaning strip 410 will exert a certain pressure on the fly waste. Finally, the fly waste will be rubbed into a fly waste ball as the cleaning strip 410 moves in the V-shaped groove 401, and finally pushed to the transfer port 402 opened on the barrier tile plate 302, and fall into the pull-out compartment 405 through the storage port 404. During the above process, the ball in the stabilizing block 411 will assist the stable movement of the cleaning strip 410. Furthermore, when the cams 304 on both sides of the barrier tile plate 302 push the barrier tile plate 302, the rotating barrier tile plate 302 will generate vibration force through the interaction between its upper protruding column 305 and semi-cylinder 306. During the vibration, the fly waste attached to the transfer port 402 and the storage port 404 will loosen, fall off, and eventually fall into the drawer 405. Moreover, the vibration force can cause the fly waste to squeeze each other during the vibration, which greatly compresses the original gaps, thereby increasing the fly waste storage capacity per unit volume of the drawer 405, extending the cleaning cycle of the drawer 405, and reducing the number of downtimes caused by operators replacing or cleaning the drawer 405. Please refer to the above work process. Figure 1 , Figures 3 to 7 .

[0048] The following is the working process of the first component 2: Furthermore, during the operation of the second component 3 and the third component 4, the cooling fan of the device is continuously running. That is, during the aforementioned process, outside air sequentially passes through the barrier tile plate 302, the second airflow hole 204, the diversion hole 206, the third airflow hole 207, and the airflow connection groove 208, and is ultimately transferred to the air-cooling channel by the cooling fan; see attached diagram. Figure 6 Appendix Figure 8 and appendix Figure 9 ; Furthermore, during the operation of the second component 3 and the third component 4, fly ash is isolated and transferred for storage. However, some fine fly ash may still pass through the first airflow hole 303 and be transferred to the chamber between the labyrinth filter plate 203 and the barrier tile plate 302. It may even pass through the filter screen of the second airflow hole 204 on the labyrinth filter plate 203 and enter the labyrinth ring 205. When fine fly ash enters the labyrinth ring 205, the long and curved channel of the labyrinth ring 205 will cause the fine fly ash that enters with the airflow to move for a longer time within the labyrinth ring 205. On the other hand, the rough sidewall of the airflow channel of the labyrinth ring 205 provides sufficient adhesion surface for fly ash. That is, the fine fly ash will gradually adhere to the sidewall under the influence of the airflow, instead of continuing to enter the cooling fan area with the airflow. This effectively cleans and removes impurities from the air medium delivered by the cooling fan, reducing the impact of fly ash on the cooling fan.

[0049] Please refer to the above work process. Figure 3 , Figure 8 , Figure 9 .
