Description

Technical Field

[0001] This application relates to the field of server technology, and more particularly to a fan device and a server. Background Technology

[0002] Currently, driven by big data and cloud computing technologies, the demand for high-performance storage and servers is growing rapidly. To ensure the stable operation of internal server components, an efficient cooling system has become a key design consideration. The use of multiple built-in fan modules is a common cooling method in high-end storage servers. These modules draw in cool external air, direct it through the front hard drive bays into the system, and then expel the hot air through the system fans, creating an effective cooling airflow.

[0003] However, in existing technologies, compatibility issues between server fan structures and cable configurations lead to reduced heat dissipation efficiency. The cable routing channels between the server fan frame and the cables are one of the main causes of airflow recirculation. Due to the diversity and uncertainty of internal server cable configurations, when the number of cables is small or there are large gaps between them, the fan airflow will pass through these cable routing channels, causing recirculation of hot air within the chassis. This significantly impacts system cooling and reduces heat dissipation efficiency. Summary of the Invention

[0011] Furthermore, the blocking element is made of a flexible material, and a rack structure is provided on one side of the blocking element; or, the blocking element includes a plurality of movable bars arranged in sequence, each movable bar being provided with a mounting protrusion, and the plurality of movable bars being movably connected by a rope.

Whether with high-density cabling or a small number of cables, optimal flow-blocking effect is achieved, effectively covering both the channel and opening sections of the cable passage, thereby sealing the gap between the cable and the passage, reducing airflow backflow from this gap, improving the cooling efficiency of the fan for internal server heat sources, and enhancing the adaptability and versatility of the fan device. Therefore, it can at least solve the technical problem in related technologies where server fans generate backflow, leading to poor heat dissipation. This significantly improves the overall heat dissipation effect of the server. Simultaneously, the improved heat dissipation helps maintain the temperature of each component inside the server within its optimal operating range, avoiding system instability caused by localized overheating, and improving the server's data processing capabilities and long-term operational reliability.

[0033] 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.

[0034] Please refer to Figures 1 to 6As shown, an embodiment of this application provides a fan device, including a mounting base 1, two frames, and a flow-blocking assembly 10; two mounting frames 2 are spaced apart on the mounting base 1, and the mounting frames 2 are used to place a fan module. A cable passage 4 for accommodating a cable 3 is formed between the two mounting frames 2. The cable passage 4 includes a channel section and an opening section; the flow-blocking assembly 10 includes a fixed base 11 and a blocking member 12. The fixed base 11 is located in the cable passage 4 and is connected to the two mounting frames 2 respectively. The fixed base 11 extends along a first direction and covers the top of the channel section; the blocking member 12 is slidably disposed on the fixed base 11. At least a portion of the blocking member 12 is slidably connected to the two mounting frames 2 along a second direction and abuts against the cable 3 to cover the opening section and restrict fluid from passing through the gap between the cable passage 4 and the cable 3; wherein the first direction and the second direction are arranged at an angle.

[0035] Through this application, due to the design of the flow-blocking component 10, at least a portion of the blocking member 12 is slidably arranged along the first and second directions, allowing for flexible adjustment based on the different quantities of cables 3 inside the server. Whether with high-density cabling or a small number of cables 3, optimal flow-blocking effect can be achieved, effectively covering the channel section and opening section of the cable passage 4, thereby sealing the gap between the cable 3 and the cable passage 4, reducing airflow backflow from this gap, improving the cooling efficiency of the fan for the server's internal heat sources, and enhancing the adaptability and versatility of the fan device. Therefore, it can at least solve the technical problem in related technologies where server fans generate backflow, resulting in poor heat dissipation. This significantly improves the overall heat dissipation effect of the server.

[0036] At the same time, the improved heat dissipation helps maintain the temperature of the internal components of the server within the optimal operating range, avoiding system instability caused by local overheating, and improving the server's data processing capabilities and long-term operational reliability.

[0037] In this embodiment, there are multiple mounting frames 2 and flow-blocking components 10. Multiple mounting frames 2 are arranged sequentially and at intervals on the mounting base 1, and each flow-blocking component 10 is arranged between two corresponding mounting frames 2.

[0038] In this embodiment, the first direction and the second direction are set perpendicular to each other.

[0039] In this embodiment, as Figure 1 and Figure 2 As shown, the fixed base 11 is provided with a first slide groove 110 extending in the first direction and an arc-shaped transition groove 111, and the mounting frame 2 is provided with a second slide groove 5 extending in the second direction. The first slide groove 110, the transition groove 111 and the second slide groove 5 are connected in sequence to form a movable track, and the blocking member 12 is slidably disposed in the movable track.

[0040] The blocking component 12 can slide within the movable track in the first and second directions, allowing it to precisely cover the channel section and opening section of the cable passage 4. Regardless of the number and configuration of cables 3, it can effectively block the gap between the cable passage 4 and the cables 3, reduce fluid backflow, thereby optimizing the airflow distribution inside the server and improving heat dissipation efficiency.

[0041] Furthermore, through the design of the movable track, the blocking component 12 can adapt to cable passages 4 of different widths and heights, as well as variations in the number and thickness of cables 3. This allows the fan unit to be applied more flexibly to various server architectures, enhancing its versatility and applicability. The sliding nature of the blocking component 12 also simplifies adjustment and replacement processes, eliminating the need for complex tools or in-depth server access. Maintenance personnel can quickly locate and resolve issues, significantly improving maintenance efficiency and convenience.

[0042] like Figures 3 to 5 As shown, the flow obstruction assembly 10 also includes a limiting member 13, which is movably disposed on the fixed base 11. The limiting member 13 has a limiting state and an active state. When the limiting member 13 is in the limiting state, at least a portion of the limiting member 13 is movably connected to the blocking member 12. The blocking member 12 is movably disposed along the direction from the first slide groove 110 to the second slide groove 5. When the blocking member 12 is in the active state, the limiting member 13 is separated from the blocking member 12, and the blocking member 12 is movably disposed.

[0043] In this way, by switching between the limiting state and the active state of the limiting member 13, the blocking member 12 is allowed to be precisely adjusted within the active track. This allows the blocking member 12 to dynamically cover the opening section according to the actual layout and quantity of the cables 3, thereby effectively reducing fluid backflow and improving the accuracy and efficiency of airflow guidance.

[0044] When the limiting member 13 is in the limiting state, the blocking member 12 is allowed to move in one direction from the first slide groove 110 to the second slide groove 5, and is locked in the opposite direction. This ensures that the blocking member 12 can move stably and is limited by the limiting member 13 after it comes into contact with the cable 3, thereby blocking the gap between the cable passage 4 and the cable 3. When adjustment or maintenance is required, the limiting member 13 can be switched to the active state, which allows the blocking member 12 to be released quickly for easy operation.

[0045] When the limiter 13 switches to the active state, it allows the blocking member 12 to move easily without effort or the use of special tools, simplifying the adjustment operation when the configuration of the internal cable 3 of the server changes, and improving the convenience of maintenance and management.

[0046] As can be seen, the reliable positioning of the blocking component 12 is ensured by the control of the limiting component 13, avoiding heat dissipation problems caused by the failure of the flow-blocking component 10, and improving the overall stability and reliability of the server operation. Furthermore, the cooperation between the limiting component 13 and the blocking component 12 enables the server to flexibly cope with different workloads and cable layouts, improving its adaptability to complex environments, and also facilitating future upgrades and expansions of the server.

[0047] In this embodiment, the limiting member 13 is disposed on the side of the fixed base 11 away from the blocking member 12. The fixed base 11 is provided with a through hole 112 communicating with the first sliding groove 110. The limiting member 13 includes a main body section 130 and a limiting section 131 that are angled and elastically connected. The blocking member 12 is provided with a plurality of mounting protrusions 120 at intervals on the side facing the through hole 112. When the limiting member 13 is in the limiting state, at least a portion of the limiting section 131 passes through the through hole 112 and extends into the space between two adjacent mounting protrusions 120 to engage with the blocking member 12.

[0048] The above configuration, through the engagement of the limiting segment 131 of the limiting member 13 with the mounting protrusion 120 on the blocking member 12, provides precise position control of the blocking member 12 on the moving track. When the limiting member 13 is in the limiting state, at least a portion of the limiting segment 131 passes through the through hole 112 and is embedded between adjacent mounting protrusions 120, ensuring that the blocking member 12 can move to the target position along the direction from the first slide groove 110 to the second slide groove 5 and be firmly fixed in the required position, avoiding positional displacement caused by airflow or vibration, and ensuring a good flow blocking effect.

[0049] The elastic connection between the main body segment 130 and the limiting segment 131 makes the transition between the active and limited states of the limiting member 13 quick and easy. Users only need to apply a slight force to the limiting segment 131 to move it into or out of the limited state, achieving rapid adjustment and locking of the position of the blocking member 12, thus improving operational efficiency.

[0050] As can be seen, the elastic connection between the main body segment 130 and the limiting segment 131 makes the transition between the active and limited states of the limiting component 13 quick and easy. Users only need to apply a slight force to the limiting segment 131 to move it into or out of the limited state, achieving rapid adjustment and locking of the position of the blocking component 12, thus improving operational efficiency. This not only enhances the adjustability and locking stability of the flow-blocking component 10 but also improves the system's maintenance convenience, reliability, and energy efficiency, facilitating efficient heat dissipation and flexible management of the server.

[0051] In this embodiment, the flow-blocking assembly 10 further includes an unlocking member 14, which is movably disposed on the fixed base 11. The unlocking member 14 has a first position and a second position. When the unlocking member 14 is in the first position, the unlocking member 14 contacts and presses against at least a portion of the limiting member 13, and the limiting member 13 is in an active state. When the unlocking member 14 is in the second position, the unlocking member 14 separates from at least a portion of the limiting member 13, and the limiting member 13 is in a limited state.

[0052] The unlocking component 14 provides an intuitive and simple operating method, allowing users to control the limiting component 13 simply by changing its position. This eliminates the need for tools or complex procedures, enabling quick adjustment of the blocking component 12's position, significantly improving maintenance and management efficiency, and simplifying the process when changing the configuration of the server's internal cables 3.

[0053] The cooperation between the unlocking component 14 and the limiting component 13 allows the blocking component 12 to move more freely within the movable track, enabling it to quickly adapt to changes in the internal cables 3 of the server according to actual needs. When the unlocking component 14 is in the first position, the blocking component 12 can move freely along the direction from the first slide 110 to the second slide 5, adjusting to the optimal position to block the gap between the cable passage 4 and the cable 3, reducing fluid backflow.

[0054] It can be seen that by using the linkage control mechanism of the unlocking component 14 and the limiting component 13, the degree of freedom of the blocking component 12 can be controlled by simple displacement, which reduces redundant or vulnerable mechanical parts in the component, improves the reliability and durability of the flow blocking component 10, and reduces the maintenance frequency and cost.

[0055] In this embodiment, the fixed base 11 is provided with a first connecting hole 113 and a second connecting hole 114 on the side opposite to the blocking member 12, and the unlocking member 14 is provided with a connecting protrusion 140; when the connecting protrusion 140 is connected to the first connecting hole 113, the unlocking member 14 is located in the first position, and when the connecting protrusion 140 is connected to the second connecting hole 114, the unlocking member 14 is located in the second position.

[0056] By connecting the protrusion 140 with the first connecting hole 113 or the second connecting hole 114, the unlocking member 14 can be accurately fixed in the first position or the second position without the need for a complicated adjustment or locking mechanism, which simplifies the operation process and improves the intuitiveness and convenience of user operation.

[0057] The positional change of the unlocking member 14 directly affects the state of the limiting member 13. When the connecting protrusion 140 is connected to the first connecting hole 113, the unlocking member 14 is in the first position. At this time, the unlocking member 14 presses against the limiting segment 131 of the limiting member 13, making it in an active state, and the blocking member 12 can be freely adjusted. When the connecting protrusion 140 is connected to the second connecting hole 114, the unlocking member 14 is in the second position, separated from the limiting segment 131 of the limiting member 13. The limiting member 13 fixes the blocking member 12, so that the blocking member 12 can only move in one direction from the first slide groove 110 to the second slide groove 5, and locks in the opposite direction, ensuring the stability of the state of the limiting member 13 and avoiding control failure caused by vibration or airflow impact during server operation.

[0058] As can be seen, the first connecting hole 113 and the second connecting hole 114 cooperate with the connecting protrusion 140 of the unlocking member 14, which not only simplifies the adjustment operation of the flow-blocking component 10 and improves the stability of the limiting member 13, but also promotes the efficient operation and economy of the server's internal heat dissipation system by optimizing the spatial layout and improving the structural strength.

[0059] In this embodiment, the blocking member 12 is made of a flexible material, and a rack structure 121 is provided on one side of the blocking member 12. Optionally, the blocking member 12 is made of nylon PA66.

[0060] Because it uses flexible materials, the blocking component 12 can better adapt to cable 3 through-holes of different sizes and shapes, as well as changes in the number of cables 3. Whether there are fewer or more cables 3, the blocking component 12 can move within the movable track along the first and second directions and abut against the cables 3 through its own deformation and adjustment, closely fitting around the cables 3, effectively sealing the gap between the cable passage 4 and the cables 3, thereby reducing airflow backflow and improving heat dissipation efficiency.

[0061] When the limiting member 13 is in the limiting state, at least a portion of the limiting segment 131 of the limiting member 13 passes through the through hole 112 and abuts against the toothed groove on the blocking member 12.

[0062] Optionally, such as Figure 6 As shown, the blocking member 12 includes a plurality of movable strips 122 arranged in sequence, each movable strip 122 is provided with a mounting protrusion 120, and the plurality of movable strips 122 are movably connected to each other by a rope 123.

[0063] The combination of the movable strip 122 and the cord 123 allows the blocking member 12 to also achieve flexible deformation, slidingly within the movable track along the first and second directions respectively. Furthermore, when the limiting member 13 is in the limiting state, at least a portion of the limiting segment 131 of the limiting member 13 passes through the through hole 112 and extends between two adjacent mounting protrusions 120 to abut against the blocking member 12. The position of the blocking member 12 can be quickly and intuitively adjusted to match different cable 3 layouts, without the need for complex manual adjustments or additional tools, greatly improving the convenience and efficiency of operation.

[0064] In this embodiment, a first mating component is provided on the fixed base 11, and a second mating component is provided on the mounting frame 2. The first mating component and the second mating component are connected to each other so that the flow-blocking component 10 is detachably connected to the mounting frame 2.

[0065] The flow-blocking assembly 10 can be easily installed and removed through the cooperation of the first and second mating parts, without the need for tools or complex assembly processes. This makes server maintenance and upgrades more convenient and allows for quick responses to changes in cable layout or heat dissipation requirements.

[0066] Furthermore, the detachable design allows maintenance personnel to replace or repair the flow-blocking component 10 individually without damaging the overall server structure, reducing maintenance time and improving server availability and stability. This design significantly reduces downtime caused by disassembly and reassembly, especially when dealing with complex cable layouts. Simultaneously, the detachable connection allows the flow-blocking component 10 to adapt to different server architectures or cooling strategies, facilitating optimized configuration under varying workloads and environmental conditions, and improving system adaptability and scalability.

[0067] Specifically, the first mating part is a movable snap fastener 115, and the second mating part is a disassembly hole 6, with the snap fastener 115 engaging with the disassembly hole 6.

[0068] The design of the snap-fit ​​component 115 and the mounting / removing hole 6 allows for quick installation and disassembly of the flow-blocking component 10. Furthermore, when maintaining or replacing the flow-blocking component 10, the operator only needs to apply appropriate force to the snap-fit ​​component 115 to pull out or insert the connector, thus separating and installing the flow-blocking component 10, significantly improving maintenance efficiency and flexibility.

[0069] Compared to traditional fixing methods, the design of the clip 115 and the mounting hole 6 is more compact, which can save space inside the server, help optimize the overall layout, and provide more installation space for other components.

[0070] Optionally, both the first mating part and the second mating part are disassembly holes 6, so that the connecting parts can be respectively inserted into the two disassembly holes 6.

[0071] In this application, the flow-blocking assembly 10 is designed for quick installation and removal: During cable 3 maintenance, the flow-blocking assembly 10 must be easily detachable. During installation, the flow-blocking assembly 10 is placed at the top of the cable passage 4, between the side walls of the two mounting frames 2. As the flow-blocking assembly 10 is lowered, the latching member 115 is deformed by the side wall of the cable passage 4. When the mounting groove 116 on the fixing base 11 engages with the mounting piece 7, it supports the flow-blocking assembly 10 at that height. At this time, the latching member 115 also springs back and inserts into the disassembly hole, completing the installation of the flow-blocking assembly 10. For disassembly, simply squeeze the latching member 115 to deform it and remove it from the disassembly hole, and the flow-blocking assembly 10 can be pulled upwards.

[0072] In this embodiment, the fixed base 11 is provided with a mounting groove 116, and the mounting frame 2 is provided with a mounting member 7 protruding from its surface on its side wall. The mounting groove 116 and the mounting member 7 are connected to each other so that the mounting member 7 supports the fixed base 11.

[0073] The mounting slot 116 and the mounting component 7 are connected to provide accurate positioning for the installation of the mounting base 11 and provide stable support for the mounting base 11. This ensures the structural stability and shock resistance of the flow-blocking component 10 during server operation and avoids component displacement or damage caused by internal server vibration or airflow impact.

[0074] In this embodiment, an opening slot 8 is provided at the top of the mounting frame 2 corresponding to the fixed base 11, so that the flow blocking component 10 can be pulled out from the wire passage 4 through the opening slot 8.

[0075] The top opening slot 8 simplifies the installation and removal process of the flow-blocking component 10. During installation, simply align the mounting slot 116 of the mounting base 11 with the mounting piece 7 and push it in; during removal, the operator can directly pull out the flow-blocking component 10 from the cable passage 4 through the top opening slot 8, without complicated disassembly steps, thus improving maintenance efficiency.

[0076] The design of the mounting slot 116 and the mounting component 7, along with the top opening slot 8, helps to optimize the internal space layout of the server. The mounting slot 116 occupies a small space and will not take up too much valuable space inside the server; while the design of the top opening slot 8 avoids the space limitations that may be encountered when removing the flow obstruction component 10 from the side or bottom of the server.

[0077] This design reduces reliance on additional fasteners or tools, lowering manufacturing and maintenance costs. Simultaneously, the quick-release design of the flow-blocking component 10 reduces server downtime due to maintenance, improving operational efficiency.

[0078] This application also provides a server including the aforementioned fan device.

[0079] With the adjustable flow-blocking component 10, the server can flexibly adjust the cable passage 4 of the blocked fan frame according to different cable configurations 3 and airflow requirements, effectively reducing airflow backflow, improving heat dissipation efficiency, and ensuring stable operation of the server under high load.

[0080] Furthermore, the combination of the blocking component 12 and the limiting component 13 of the flow obstruction component 10, as well as the quick adjustment function of the unlocking component 14, ensures the reliability of the airflow guidance inside the server. Even when the server is running continuously or vibrating, the flow obstruction effect can be kept stable, thereby improving heat dissipation efficiency and reducing the risk of hardware failure and downtime.

[0081] Furthermore, the fan device with adjustable flow-blocking component 10 can adapt to different cable densities and configurations inside the server, such as no cable 3, few cable 3, or many cable 3 configurations. No matter how the server configuration changes, the flow-blocking component 10 can effectively block the cable passage 4 and maintain good heat dissipation performance.

[0082] The present application provides a detailed description of a fan device and a server. Specific examples have been used to illustrate the principles and implementation methods of the present application. The descriptions of these embodiments are merely illustrative and are intended to help understand the method and core concepts of the present application. It should be noted that those skilled in the art can make various improvements and modifications to the present application without departing from its principles, and these improvements and modifications also fall within the scope of protection of the claims of this application.
