[0001] This application relates to the field of thermal management technology, and in particular to a heat dissipation and dust removal device. Background Technology

[0002] In the era of big data, a large number of IT devices are centrally located in data centers. These data centers contain various types of servers, storage, switches, and numerous racks and other infrastructure. Each type of IT device is composed of various hardware boards, such as computing modules, storage modules, chassis, fan modules, and so on. The integration of various modules within servers generates a significant amount of heat, necessitating timely heat dissipation. Among the many server cooling designs, air cooling is the most widely used approach across various application scenarios.

[0003] However, while current data centers have solved the heat dissipation problem to some extent, their airflow channels are open during normal operation, and there are no corresponding interception, filtration, or adsorption measures, which makes it impossible to perform dust removal functions, and dust accumulation is likely to occur inside the data center.

[0008] Furthermore, a dust collection box is provided at the bottom of the first housing, the dust collection box including a dust collection trough communicating with the dust removal space to collect the falling dust from the dust removal space.

[0009] Furthermore, the dust removal component also includes a toggle member, which is movably disposed in the dust collection trough and contacts the end of the first brush bristles, so as to agitate the dust adsorbed on the first brush bristles and make it fall off when the first brush bristles pass by the toggle member.

[0010] Furthermore, the actuating element also includes: a guide shaft slidably passing through the bottom of the dust collection trough; an actuating wedge block disposed in the dust collection trough and connected to the upper end of the guide shaft, the actuating wedge block including an actuating inclined surface located on the side of the actuating wedge block near the first bristles for contacting the first bristles; and an elastic element sleeved on the guide shaft and located between the bottom surface of the dust collection trough and the actuating wedge block.

[0011] Furthermore, the heat dissipation and dust removal device also includes a dust filter component. A drive component is disposed between the dust removal component and the dust filter component. The second power output end of the drive component is driven and connected to the power input end of the dust filter component. The end of the second dust removal channel away from the air outlet duct is connected to the dust filter space of the dust filter component. The dust filter component is used to filter dust from the dust removal component.

[0012] Furthermore, the dust removal component includes a first housing, the first housing including a dust removal space, and the dust filtration component includes: a second housing, the second housing including a dust filtration space; a connecting pipe, the connecting pipe being located between the first housing and the second housing and communicating with both the dust removal space and the dust filtration space; a second roller, located within the dust filtration space, the input end of the second roller being connected to the second output end of the drive component; a second brush, the second brush including multiple rows of second bristles spaced circumferentially around the second roller, each row of second bristles including multiple second bristles arranged along the axial direction of the second roller, each second bristle contacting the inner wall surface of the second housing; and a spray pipe, the fixed end of the spray pipe being located above the second housing, the output end of the spray pipe extending into the dust filtration space.

[0014] Furthermore, the dust filtration component also includes an exhaust duct, which is located on one side of the second housing and is connected to the dust filtration space to discharge the gas inside the dust filtration space.

[0015] Thus, the heat dissipation and dust removal device of this application, by setting up a first dust removal channel and a second dust removal channel, which are respectively connected to the air inlet duct and the air outlet duct, forms an effective dual-channel airflow structure. The design of the dust removal and filtration components ensures that the air entering the heat-dissipating component undergoes a first dust removal process, and then undergoes a second dust removal process after exiting the heat-dissipating component, thereby improving air cleanliness and reducing the impact of dust on heat dissipation efficiency. The air inlet duct and the air outlet duct of this application are connected in series through the first dust removal channel to ensure the cleanliness of the incoming air, while the output end of the air outlet duct is directly connected to the input end of the heat-dissipating component, reducing unnecessary losses during the air intake and exhaust process and improving heat dissipation efficiency. Similarly, the connection between the air outlet duct and the second dust removal channel ensures the further purification of the exhaust air, preventing dust from being directly emitted into the environment. Due to the presence of the dust removal components, even in high-dust environments, the heat dissipation and dust removal device can continuously provide clean air to the heat-dissipating component, avoiding the decline in heat dissipation performance caused by dust accumulation, ensuring the stable operation of the system and improving the service life of the equipment, effectively solving the problem that heat dissipation structures in related technologies cannot simultaneously perform dust removal functions.

[0034] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] like Figures 1 to 5 As shown, an embodiment of this application provides a heat dissipation and dust removal device, including: an air inlet duct 10 connected to an external air supply component; an air supply duct 20, the input end of which is connected to the air inlet duct 10, and the output end of which is connected to the input end of the component to be cooled; an air outlet duct 30, which is spaced apart from the air supply duct 20 along a first direction, and the input end of the air outlet duct 30 is connected to the output end of the component to be cooled; and a dust removal component 40, which includes a first dust removal channel 410 and a second dust removal channel 420, wherein the air inlet duct 10 is connected to the air supply duct 20 through the first dust removal channel 410, and the second dust removal channel 420 is connected to the output end of the air outlet duct 30.

[0036] As can be seen, the heat dissipation and dust removal device of this application forms an effective dual-channel airflow structure by setting a first dust removal channel 410 and a second dust removal channel 420, which are respectively connected to the air inlet duct 10 and the air outlet duct 30. The design of the dust removal component 40 and the dust filter component 70 ensures that the air entering the heat dissipation component undergoes a first dust removal, and the air after exiting the heat dissipation component undergoes a second dust removal, thereby improving the cleanliness of the air and reducing the impact of dust on the heat dissipation efficiency. The air inlet duct 10 and the air outlet duct 20 of this application are connected in series through the first dust removal channel 410 to ensure the cleanliness of the incoming air, while the output end of the air outlet duct 20 is directly connected to the input end of the heat dissipation component, reducing unnecessary losses of air during the process of air entering and exiting, and improving the heat dissipation efficiency. Similarly, the connection between the exhaust duct 30 and the second dust removal channel 420 ensures the re-purification of the exhaust air, preventing dust from being directly emitted into the environment. Due to the presence of the dust removal component 40, even in high dust environments, the heat dissipation and dust removal device can continuously provide clean air to the heat dissipation components, preventing the heat dissipation performance from declining due to dust accumulation, ensuring the stable operation of the system and improving the service life of the equipment, effectively solving the problem that the heat dissipation structure in related technologies cannot take into account the dust removal function.

[0037] like Figure 3 and Figure 5 As shown, the heat dissipation and dust removal device also includes a drive component 50, the first power output end of the drive component 50 being drivenly connected to the power input end of the dust removal component 40, wherein a speed reduction component 60 is provided between the first power output end and the dust removal component 40.

[0038] Preferably, by combining the drive component 50 and the reduction component 60, the operating speed of the dust removal component 40 can be precisely controlled. The effective operation of the dust removal component 40 often requires a specific speed range. Too fast or too slow speeds may affect the dust removal efficiency. The reduction component 60 can ensure that the dust removal component 40 operates within the optimal speed range, thereby improving the dust removal effect and avoiding the noise and energy consumption problems caused by high-speed operation.

[0039] The presence of the reduction gear 60 in this application lowers the actual rotational speed transmitted from the drive component 50 to the dust removal component 40, thus reducing wear on the dust removal component 40 and extending its service life. Furthermore, an appropriate rotational speed also helps reduce heat generated by friction, further ensuring the operational stability of the entire device.

[0040] In this application, the drive component 50 is responsible for providing power, while the reduction component 60 regulates the transmission of this power. This separate design helps improve the reliability of the system because the failure of either component will not immediately cause the entire device to fail. The drive component 50 can be a motor or other power source, while the reduction component 60 is responsible for smoothly and efficiently transmitting power to the dust removal component 40, ensuring stable operation of the device under various conditions. Furthermore, the use of the reduction component 60 allows the drive component 50 and the dust removal component 40 to be maintained independently, reducing the overall cost and complexity of maintenance, which further simplifies the maintenance process.

[0041] like Figure 3 and Figure 4 As shown, the dust removal component 40 includes: a first housing 401, the first housing 401 including a dust removal space 4011, the dust removal space 4011 being connected to both the first dust removal channel 410 and the second dust removal channel 420; a first roller 402, located within the dust removal space 4011, the power input end of the first roller 402 being connected to the first power output end of the drive component 50; and a first brush 403, the first brush 403 including multiple rows of first bristles circumferentially spaced around the first roller 402, each row of first bristles including multiple first bristles arranged along the axial direction of the first roller 402, each first bristle contacting the inner wall surface of the first housing 401.

[0042] Preferably, a plurality of isolation plates are installed on the first shaft roller 402, and the plurality of isolation plates are spaced apart around the rotation axis of the first shaft roller 402, and a plurality of rows of first bristles are arranged between two isolation plates.

[0043] Preferably, the first brush 403, with its multi-row bristle design, is in close contact with the inner wall of the first housing 401, forming an effective dust removal space 4011. As the first roller 402 rotates, the first bristles can capture and remove dust from the air passing through the first dust removal channel 410 and the second dust removal channel 420, greatly improving dust removal efficiency, maintaining air quality, and thus enhancing heat dissipation performance. The rotation of the first roller 402 brings about a dynamic cleaning effect of the first brush 403. Compared with a static filter, this dynamic cleaning mechanism can continuously remove dust accumulated on the bristles, avoiding the problems of increased airflow resistance and decreased heat dissipation efficiency caused by dust accumulation.

[0044] Furthermore, the dynamic cleaning mechanism of this application reduces the need for additional cleaning equipment and lowers energy consumption. The structural design of the first roller 402 and the first brush 403 makes maintenance and cleaning more convenient, reducing maintenance costs and downtime. Through the coordination of the reduction component 60 between the first roller 402 and the drive component 50, the rotation speed of the first brush 403 is ensured to be within a suitable range, which avoids energy waste caused by excessive rotation speed and ensures sufficient dust removal effect, making the system operation more stable.

[0045] Specifically, a dust collection box 404 is provided at the bottom of the first housing 401. The dust collection box 404 includes a dust collection trough 4041 that communicates with the dust removal space 4011 to collect dust falling from the dust removal space 4011.

[0046] The interconnected design of the dust collection trough 4041 and the dust removal space 4011 in this application can effectively capture and collect the dust separated from the air when the first brush 403 is working, preventing the dust from re-entering the airflow circulation, ensuring continuous air purification and unobstructed heat dissipation channels; and the setting of the dust collection box 404 ensures that the dust is collected rather than scattered into the environment after the air discharged from the heat dissipation component is purified again by the second dust removal channel 420 and the dust removal component 40, reducing pollution to the surrounding environment and improving the environmental performance of the device.

[0047] Preferably, the dust collection box 404 is an independent module, which is convenient to open regularly for dust cleaning, simplifying the maintenance process, reducing maintenance costs, and also reducing the time that the equipment needs to be shut down for cleaning due to dust accumulation. By collecting dust through the dust collection box 404, the impact of dust on other components such as the air supply duct 20 and the air outlet duct 30 is reduced, avoiding blockage or performance degradation caused by dust, thereby improving the working efficiency and reliability of the entire heat dissipation and dust removal device.

[0048] like Figure 4 As shown, the dust removal component 40 also includes a toggle member 405, which is movably disposed in the dust collection groove 4041 and contacts the end of the first brush bristles so as to agitate the dust adsorbed on the first brush bristles to fall off when the first brush bristles pass through the toggle member 405.

[0049] The movable feature of the agitator 405 within the dust collection groove 4041 allows it to contact the end of the first brush bristles. As the bristles pass by, they vibrate, causing the attached dust particles to loosen and fall, thus removing dust more thoroughly and improving dust removal efficiency. Furthermore, through mechanical vibration, the agitator 405 prevents dust from re-attaching to the first brush bristles, reducing dust circulation in the airflow, avoiding secondary pollution, and ensuring that the air entering the heat dissipation component is cleaner.

[0050] The design of the actuating element 405 in this application simplifies the maintenance process of the dust removal component 40. Operators only need to move or replace the actuating element 405 periodically, without the need for complex cleaning of the entire first brush bristles, which reduces maintenance costs and downtime, and improves the availability and economy of the equipment. The actuating element 405 cleans dust mechanically, reducing the impact of physical wear on the first brush bristles, extending the service life of the dust removal component 40, and reducing maintenance requirements under long-term operation.

[0051] Preferably, effective dust removal reduces the risk of airflow channel blockage, ensures unobstructed airflow, maintains high system reliability, and avoids equipment overheating or malfunction due to poor heat dissipation. The contact method between the actuating element 405 and the first brush bristles enables automated cleaning. In some embodiments, the movement of the actuating element 405 can be automatically controlled by a drive mechanism to achieve periodic automatic cleaning, reducing manual operation and improving the convenience and efficiency of operation.

[0052] Specifically, the actuating element 405 further includes: a guide shaft 4051, which is slidably disposed at the bottom of the dust collection groove 4041; an actuating wedge 4052, which is disposed in the dust collection groove 4041 and connected to the upper end of the guide shaft 4051, the actuating wedge 4052 including an actuating inclined surface 4053, the actuating inclined surface 4053 being located on the side of the actuating wedge 4052 near the first bristles for contacting the first bristles; and an elastic element 4054, which is sleeved on the guide shaft 4051 and located between the bottom surface of the dust collection groove 4041 and the actuating wedge 4052.

[0053] Preferably, the guide shaft 4051 guides and supports the actuating wedge 4052, and the elastic element 4054 supports the actuating wedge 4052 to contact the first brush 403. In this application, when the actuating inclined surface 4053 on the actuating wedge 4052 contacts the first brush bristles, the inclined surface structure of the actuating wedge 4052 generates pressure when the brush bristles pass by, causing the dust adsorbed on the brush bristles to fall off due to friction and vibration and fall into the dust collection groove 4041, effectively improving the dust removal rate.

[0054] The sliding connection between the guide shaft 4051 and the actuating wedge 4052, as well as the function of the elastic element 4054, enable the actuating element 405 to dynamically adjust according to changes in airflow pressure and bristle thickness, ensuring the optimal contact angle with the bristles and adapting to different operating conditions.

[0055] The presence of the elastic element 4054 buffers the impact force when the actuating wedge 4052 contacts the first brush bristles, reduces mechanical wear between the two, extends the service life of the components, and reduces the maintenance frequency.

[0056] The optimized dust-shaking mechanism in this application reduces the risk of blockage in the heat dissipation channels, ensures smooth airflow, thereby improving the overall operational reliability of the system and avoiding equipment overheating and malfunctions caused by poor heat dissipation. The sliding design of the toggle element 405 and the simple structure of the elastic element 4054 make the maintenance and cleaning process more convenient. Only the dust in the dust collection tank 4041 needs to be cleaned periodically, without the need for frequent replacement or adjustment of parts, thus reducing maintenance costs. Moreover, compared with traditional manual or electric cleaning methods, this application achieves automated dust shaking through a simple mechanical structure, reducing manufacturing costs and operating energy consumption.

[0057] like Figure 3 As shown, the heat dissipation and dust removal device also includes a dust filter component 70. A drive component 50 is disposed between the dust removal component 40 and the dust filter component 70. The second power output end of the drive component 50 is driven to be connected to the power input end of the dust filter component 70. The end of the second dust removal channel 420 away from the air outlet duct 30 is connected to the dust filter space 710 of the dust filter component 70. The dust filter component 70 is used to filter dust from the dust removal component 40.

[0058] As a secondary purification unit, the dust filter component 70 further filters the air that has undergone preliminary treatment by the dust removal component 40, capturing and removing even finer dust particles, thus further improving air cleanliness. This dual purification mechanism ensures the quality of air entering the heat-dissipating components and improves heat dissipation efficiency. Designing the drive connection between the drive component 50 and the dust filter component 70 independent of the dust removal component 40 allows the dust filter component 70 to be maintained and cleaned independently without affecting the operation of the entire system. This not only simplifies the maintenance process but also improves maintenance efficiency and reduces maintenance costs.

[0059] The presence of the dust filter component 70 in this application reduces the dependence of the heat-dissipating component on air cleanliness, reduces the failure of internal parts caused by dust wear, thereby extending the service life of the heat-dissipating component and even the entire equipment; and the addition of the dust filter component 70 further reduces dust in the airflow, reduces the risk of heat dissipation channel blockage, improves the overall operational reliability of the system, and ensures a continuous and stable heat dissipation effect.

[0060] like Figure 4As shown, the dust removal component 40 includes a first housing 401, which includes a dust removal space 4011. The dust filtration component 70 includes: a second housing 720, which includes a dust filtration space 710; a connecting pipe 730, located between the first housing 401 and the second housing 720, and connected to both the dust removal space 4011 and the dust filtration space 710; and a second roller 740, located within the dust filtration space 710, with its input end connected to the drive component 50. The second output end is connected; the second brush 750 includes multiple rows of second bristles spaced circumferentially around the second shaft roller 740 on the second shaft roller 740, each row of second bristles includes multiple second bristles arranged along the axial direction of the second shaft roller 740, and each second bristle is in contact with the inner wall surface of the second housing 720; the spray pipe 760 has a fixed end located above the second housing 720, and the output end of the spray pipe 760 extends into the dust filter space 710.

[0061] Multiple isolation plates are installed on the second shaft roller 740. The multiple isolation plates are spaced apart around the rotation axis of the second shaft roller 740, and multiple rows of second bristles are arranged between two isolation plates.

[0062] Preferably, the second brush 750, with its multi-row design, makes close contact with the inner wall of the second housing 720, which can further capture residual dust particles when the airflow passes through the dust filter space 710, improve the cleanliness of the air, provide cleaner cooling air for the components to be cooled, and enhance the heat dissipation performance.

[0063] Compared to the dry dust removal of the first brush 403, the second brush 750, in conjunction with the spray pipe 760, can capture and adhere to tiny dust particles, especially dust that is difficult to remove in dry environments. By using a wet dust removal method, the removal rate of fine particles is significantly improved.

[0064] The second roller 740 of this application is connected to the second power output end of the drive component 50, so that it rotates under the guidance of airflow, driving the second brush 750 to clean dynamically, avoiding the accumulation of dust on the second brush bristles, maintaining a good filtration effect, and extending the service life of the dust filter component; the dust filter component 70 and the dust removal component 40 are independently connected through the connecting pipe 730, which can be maintained and cleaned separately, reducing the difficulty of maintenance and improving the maintainability and operating efficiency of the equipment.

[0065] This application reduces the erosion of heat sinks and internal components by micro-dust through an efficient dust filtration and removal mechanism, thereby reducing equipment failure rate, extending equipment lifespan, and improving system reliability.

[0066] like Figure 4As shown, the dust filter component 70 further includes: a liquid collection tank 701, which is disposed at the bottom of the second housing 720. The liquid collection tank 701 includes a liquid collection groove 7011 communicating with the dust filter space 710 for collecting dust-laden liquid falling from the dust filter space 710; and a drain pipe 702 communicating with the bottom of the liquid collection tank 701 for discharging the dust-laden liquid in the liquid collection groove 7011.

[0067] The liquid collection tank 701 is specifically designed to collect the liquid carrying dust after spray purification, further enhancing the wet dust removal effect within the second housing 720. This ensures that dust particles mixed with water can be effectively captured and stored, rather than being re-dispersed into the air, thus improving the thoroughness and efficiency of dust removal. Furthermore, the combination of the liquid collection tank 701 and the drain pipe 702 provides a convenient liquid discharge route, making it easier to periodically clean the dust filter component 70 without disassembling the entire device. At the same time, the centralized treatment of the dust-laden liquid through the drain pipe 702 reduces secondary pollution to the environment.

[0068] This application prevents dust-laden liquid from accumulating in the filter space 710, thus avoiding airflow obstruction or equipment corrosion caused by liquid accumulation and ensuring long-term stable operation of the equipment. Furthermore, the design of the liquid collection tank 701 and the drain pipe 702 reduces maintenance costs, and wet dust removal reduces the need for expensive filter media.

[0069] like Figure 5 As shown, the dust filter component 70 also includes an exhaust duct 703, which is disposed on one side of the second housing 720 and is connected to the dust filter space 710 to discharge the gas in the dust filter space 710.

[0070] In this application, the dust-laden airflow enters the second housing 720 through the connecting pipe 730. The spray pipe 760 on the second housing 720 sprays dust into the dust filter space 710. Then, the water mist is intercepted by the second brush 750. The water mist intercepted by the second brush 750 is centrifugally thrown onto the inner wall of the second housing 720 under the action of the rotation of the second brush 750. Then, it flows into the collection tank 701 under the action of gravity, and is then discharged through the drain pipe 702. The purified air is then discharged through the exhaust pipe 703. This application achieves a certain dust removal effect while achieving a certain purification effect on the air in the server room.

[0071] The exhaust duct 703 ensures that the air purified by the dust filter space 710 can be smoothly discharged, avoiding the stagnation or backflow of purified air inside the system, ensuring the quality of the output air, providing a cleaner cooling airflow for the heat-dissipating components, and enhancing the heat dissipation effect; the exhaust duct 703 is connected to the dust filter space 710, which promotes the balance of airflow, avoids the problem of excessively high or low air pressure, and ensures the stability of the system throughout the entire operation process.

[0072] The location design of the exhaust duct 703 in this application optimizes the spatial layout of the entire device, making the airflow path between the dust filter component 70 and other components more reasonable. This not only saves installation space but also improves the integration of the device.

[0073] The design of the exhaust duct 703 also facilitates regular inspection and cleaning, ensuring unobstructed flow, reducing maintenance difficulty, and contributing to the long-term stable operation of the system. It also reduces maintenance costs caused by duct blockage.
