Flow control device and server

Abstract

This application discloses a flow-blocking device and a server, relating to the field of server heat dissipation technology. It includes a fan frame assembly and a baffle assembly. When no cable passes through the cable passage gap or when sealing the gap is required, the baffle rotates around its longitudinal axis to close, effectively blocking any potential airflow channels. When cable passage is required, the baffle can rotate around its longitudinal axis to open, allowing cables to pass through the gap. After cable installation, some of the pushed-open baffles can remain open with the support of the cables, but the cables and the baffles adjacent to them still block the gaps around the cables to the maximum extent possible. This allows cables to pass flexibly through the gaps while maximally sealing them, reducing ineffective airflow leakage and hot air recirculation, and improving the fan's heat dissipation efficiency.

Description

Technical Field

[0001] This application relates to the field of server heat dissipation technology, and in particular to a flow-blocking device and a server. Background Technology

[0002] With the continuous development of big data and cloud computing technologies, high-performance storage and servers are in high demand. Built-in multiple fan modules are a typical heat dissipation method for high-end storage servers. The function of the built-in fan is to draw air in from outside the system, pass through the front hard drive to the system fan, and then the system fan blows the air to the motherboard and other boards and components behind the fan.

[0003] Servers have many requirements, and cables must be used to connect the backboards and the system. Cable configuration is flexible, and additional channels for cable routing need to be reserved inside the rack. The fan airflow will pass through these gaps and generate backflow, resulting in a significant loss of cooling airflow. Hot air circulates inside the rack, which will affect the performance of the fans and the overall cooling effect of the machine. Summary of the Invention

[0004] This application provides a flow-blocking device and a server to at least solve the problem in related technologies where airflow can easily backflow in the cable passage, affecting the overall heat dissipation of the server.

[0005] This application provides a flow-blocking device, comprising: A fan frame assembly is installed in a server rack. The fan frame assembly has at least one fan mounting position for installing a fan. The fan frame assembly is configured to be at least one, and a cable passage gap for arranging cables is formed between the fan frame assembly and the inner wall of the rack or between adjacent fan frame assemblies. The cable passage gap has opposing first sidewalls and second sidewalls. A windbreak assembly is disposed at the cable passage gap. The windbreak assembly includes a longitudinal axis and multiple windbreak components. The longitudinal axis is disposed on the first side wall. The multiple windbreak components are stacked sequentially on the longitudinal axis along the height direction. Each windbreak component is rotatably disposed on the longitudinal axis independently. The windbreak component has an open state that is parallel to the extension direction of the cable to avoid the cable passing through, and a closed state that intersects the extension direction of the cable to block the cable passage gap.

[0006] This application also provides a server, including: a rack and a flow-blocking device as described above, wherein a fan frame assembly of the flow-blocking device is installed in the rack, and a wind-blocking assembly of the flow-blocking device is installed between the fan frame assembly and the inner wall of the rack, or between adjacent fan frame assemblies.

[0007] This application enables the following: When no cable passes through the cable passage gap or when sealing the gap is required, the baffle rotates around its longitudinal axis to close, effectively blocking any potential airflow channels and preventing cooling airflow from the fan from leaking and forming backflow. When a cable is needed, the baffle rotates around its longitudinal axis to open, parallel to the cable's extension direction to avoid cable passage and facilitate cable passage through the gap. After cable installation, some of the pushed-open baffles remain open with cable support, but the cable and adjacent baffles above and below it still block the gap around the cable to the maximum extent. This achieves a dynamic adaptive effect of "baffle on demand" based on the actual cabling situation, allowing cables to pass flexibly through the gap while maximizing the sealing of the gap around the cable, reducing ineffective airflow leakage and hot air backflow, improving fan cooling efficiency, ensuring sufficient and directional cooling airflow for critical components within the server, and enhancing the overall system's cooling performance and operational reliability.

[0013] 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.

[0014] Reference Figures 1 to 6 As shown, an embodiment of this application provides a flow-blocking device, including a fan frame assembly 1 and a wind deflector assembly 2.

[0015] The fan frame assembly 1 is installed in the server rack. The fan frame assembly 1 has at least one fan mounting position 11 for installing a fan. Each fan mounting position 11 is used to fix an independent cooling fan. The fan frame assembly 1 can be made of metal sheet (such as galvanized steel sheet or aluminum alloy) through stamping, bending, welding or riveting processes, and has high structural strength and rigidity.

[0016] The fan frame assembly 1 is configured to be at least one, and a cable passage gap 12 for arranging cables is formed between the fan frame assembly 1 and the inner wall of the cabinet or between adjacent fan frame assemblies 1. The cable passage gap 12 has a first sidewall 121 and a second sidewall 122 opposite to each other.

[0017] When the fan frame assembly 1 is set to one, a wire passage gap 12 is formed between the fan frame assembly 1 and the inner wall of the cabinet. The first side wall 121 and the second side wall 122 are the side wall of the fan frame assembly 1 and the inner wall of the cabinet, respectively.

[0018] When the server system is large, multiple independent fan frame assemblies 1 can be installed side by side. Each fan frame assembly 1 is fixed inside the server rack by screws or clips. Cable clearances 12 are formed between the fan frame assembly 1 and the inner wall of the rack, and between two adjacent fan frame assemblies 1. The first side wall 121 and the second side wall 122 are the side wall of the fan frame assembly 1 and the inner wall of the rack, respectively, or they are the two opposite side walls of two adjacent fan frame assemblies 1.

[0019] A windbreak assembly 2 is installed at the cable passage gap 12. The windbreak assembly 2 includes a longitudinal axis 21 and multiple windbreak components 22. The longitudinal axis 21 is mounted on the first side wall 121. The multiple windbreak components 22 are stacked sequentially along the longitudinal axis 21 along the height direction. Each windbreak component 22 is rotatably mounted on the longitudinal axis 21 independently. The windbreak component 22 has an open state that is parallel to the cable extension direction to avoid the cable passing through, and a closed state that intersects the cable extension direction to block the cable passage gap 12. The switching between the open and closed states can be achieved manually by the operator.

[0020] Specifically, when cabling or adjusting is required, operators can manually or with the aid of tools rotate one or more wind deflectors 22 to the open position. At this point, the wind deflector 22 has its minimum frontal area, maximizing space for cable passage, allowing the cable to easily pass through the gap. Once the cabling is complete, the portion of the wind deflector 22 above or below the cable is rotated to the closed position to seal the cable passage gap 12, preventing the cooling airflow from the fan from leaking or forming a backflow. This effectively reduces the fan's backflow and improves the server's cooling performance.

[0021] Understandably, the wind deflector 22 rotates and opens, and its direction of movement and the required space for movement are compatible with the cable routing direction. This allows it to adapt to applications with height restrictions without taking up extra space. It is suitable for the internal space layout of server racks, and is especially suitable for compact chassis, AI servers, etc.

[0022] Through this application, when no cable passes through the cable passage gap 12 or when sealing the cable passage gap 12 is required, the baffle 22 rotates around the longitudinal axis 21 to close, and the baffle 22 lies across the cross-section of the cable passage gap 12, effectively blocking any possible airflow channels and preventing the cooling airflow generated by the fan from leaking out and forming backflow. When there is a need for cable passage, the baffle 22 can rotate around the longitudinal axis 21 to open, and in this state, the baffle 22 is parallel to the cable extension direction to avoid cable passage and facilitate cable passage through the cable passage gap 12. After the cable is laid, the partially opened baffle 22 can... While remaining open with the support of the cable, the cable and the adjacent wind deflectors 22 still block the gaps around the cable to the maximum extent, achieving a dynamic adaptive effect of "wind deflection on demand" according to the actual cabling situation. This allows the cable to pass flexibly within the cable passage gap 12 while blocking the cable passage gap 12 to the maximum extent around the cable, meeting the flexible requirements of various cable configurations and improving the compatibility of the flow obstruction device. It also reduces ineffective airflow leakage and hot air recirculation, improves the cooling efficiency of the fan, ensures that key components in the server can obtain sufficient and directional cooling airflow, and improves the heat dissipation efficiency and operational reliability of the entire system.

[0023] In a specific implementation, the wind deflector 22 has a through hole, and the longitudinal shaft 21 is inserted into the through hole. The wind deflector 22 can move relative to the longitudinal shaft 21 along the axial direction, and can also rotate about the axis. The longitudinal shaft 21 can be fixedly connected to the first side wall 121 by fasteners such as screws.

[0024] Reference Figures 1 to 3As shown, the windbreak assembly 2 is located at the end of the wire passage gap 12 to facilitate the rotation of the windbreak component 22 and avoid problems such as motion interference. Of course, the windbreak assembly 2 can also be located in the middle of the wire passage gap 12. This application does not limit this and can be set according to actual needs and specific space size.

[0025] In some embodiments, refer to Figure 4 As shown, the wind deflector 22 and the longitudinal shaft 21 slide together along the height direction. When the inner diameter of the through hole on the wind deflector 22 is slightly larger than the outer diameter of the longitudinal shaft 21, the wind deflector 22 is allowed to move relative to the longitudinal shaft 21 along the axial direction, and the wind deflector 22 can also rotate around the axis.

[0026] An elastic element 23 is provided between the top of the longitudinal axis 21 and the top windbreak 22, so that when a cable passes through the cable passage gap 12, the windbreak 22 can be elastically pressed against the top of the cable. That is, when a cable passes through the cable passage gap 12, the cable occupies the space in the height direction of its passage path. The windbreaks 22 within the cable passage height range open, and the windbreaks 22 at other heights can be tightly pressed together by the elastic pressure from above, and the windbreak 22 at the top of the cable can also be pressed firmly against the cable. With this arrangement, all windbreaks 22 can fit tightly together for cables of different specifications and sizes, and most gaps are effectively pressed and sealed, greatly reducing the possibility of air leakage.

[0027] Specifically, a baffle is provided at the top of the longitudinal axis 21, and an elastic element 23 is provided between the baffle and the windproof element 22 located at the top, so as to apply elastic pressure to the windproof element 22 through the baffle and the elastic element 23.

[0028] In some embodiments, the wind deflector 22 slides in conjunction with the longitudinal axis 21 along the height direction. The top surface of the wind deflector 22 has a groove 221, and the bottom surface of the wind deflector 22 has a protrusion 222. The protrusion 222 can be inserted into the groove 221 along the height direction and can also be dislodged from the groove 221. It is understood that, under natural conditions, due to gravity or a slight preload, the protrusion 222 of the upper wind deflector 22 can be inserted into the groove 221 of the lower wind deflector 22, forming a simple vertical positioning and linkage to prevent misalignment between adjacent wind deflectors 22 and ensure the wind-blocking effect.

[0029] Reference Figure 4 The multiple wind deflectors 22 are divided into two parts. One part is in the open state, and the wind deflectors 22 in this part can be kept at the same angle through the cooperation of the protrusions 222 and the grooves 221. The other part is in the closed state to abut against the top of the cable.

[0030] When wind protection is needed, refer to Figure 2As shown, the operator overcomes the elastic force of the elastic member 23 to lift part of the windshield member 22, so that the engagement between the protrusion 222 and the groove 221 between two adjacent windshield members 22 is released. At this time, the adjacent windshield members 22 can rotate relative to each other. (Refer to...) Figure 3 As shown, when the operator removes the external force, the upper windbreak 22, under the action of elastic restoring force, can elastically press against the top of the cable, enabling quick adjustment and reliable fixation between the open and closed states of the windbreak 22, thus improving the efficiency of cable installation and disassembly. Specifically, the protrusion 222 elastically presses against the top of the cable. It should be noted that, due to the setting of the elastic element 23, the protrusion 222 is allowed to occupy a certain amount of additional height space.

[0031] In practice, the groove 221 can be a blind hole or a through hole, with a cross-sectional shape of circular, square, or other regular shapes. Correspondingly, a protrusion 222 matching the shape and size of the groove 221 is provided on the bottom surface of each windbreak 22. The protrusion 222 can be integrally formed with or fixedly connected to the body of the windbreak 22.

[0032] In the vertical direction, in at least two adjacent wind deflectors 22, the protrusion 222 of the upper wind deflector 22 abuts against the outer wall surface of the lower wind deflector 22 and presses against the top of the cable. That is, referring to... Figure 4 As shown, the protrusion 222 of the upper wind deflector 22 abuts against the outer wall of the lower wind deflector 22. This arrangement, through the contact between the protrusion 222 and the outer wall of the wind deflector 22, allows adjacent wind deflectors 22 to maintain a fixed angle for flow obstruction and wind blocking.

[0033] In some embodiments, the protrusion 222 is formed as a cuboid structure, having two large faces opposite each other along a first direction and two small faces opposite each other along a second direction, the second direction being perpendicular to the first direction. The first direction is parallel to the shorter edge, and the two sides opposite each other along the first direction have larger areas, forming large faces; the second direction is parallel to the longest edge of the cuboid, and the two sides opposite each other along the second direction have smaller areas, forming small faces, and the first direction is perpendicular to the second direction.

[0034] The small facet of the protrusion 222 pressed against the top of the cable abuts against the outer wall surface of the windproof member 22 located below. That is, in Figure 4 In the scenario of partial threading, when the protrusion 222 of the upper windshield 22 needs to abut against the outer wall surface of the lower windshield 22, the abutment is made by a small surface of the protrusion 222. Specifically, one side (small surface) of the protrusion 222 along its length direction (i.e., the second direction) contacts the outer wall surface of the lower windshield 22, and the contact area is small.

[0035] When the protrusion 222 abuts against the wind deflector 22 with its small facet, it still retains a small amount of room for movement in the direction of rotation of the wind deflector 22. This allows the upper wind deflector 22 to make a small adaptive deflection around the longitudinal axis 21 when subjected to lateral wind force or when its position needs to be finely adjusted to better compress the irregular cable bundle below, without getting stuck due to large-area contact. At the same time, the protrusion 222 and the outer wall surface of the wind deflector 22 still maintain surface contact, which can properly ensure that the included angle between two adjacent wind deflectors 22 is fixed and avoid swaying due to airflow.

[0036] In some embodiments, a cover plate 24 is provided on the top of the wire passage gap 12. The cover plate 24 is rotatably connected to the first side wall 121 to cover the top of the wire passage gap 12 or to open to expose the wire passage gap 12, so that the top of the wire passage gap 12 is completely sealed when a cable passes through the wire passage gap 12; and when it is necessary to lay cables, it is convenient for cables to pass through the top of the wire passage gap 12 for wiring.

[0037] Specifically, the cover plate 24 can be hinged to the first sidewall 121 at the top of the wire passage gap 12 via a hinge, pivot, pin or other rotating connector. The cover plate 24 is a plate-shaped piece that matches the shape of the opening at the top of the wire passage gap 12 and can be opened or closed relative to the rotation center.

[0038] Furthermore, a retaining plate 241 is provided on the cover plate 24. When the cover plate 24 is placed on top of the wire passage gap 12, at least one of the top windbreak members 22 is in a closed state, and the retaining plate 241 is engaged in the groove 221 of the top windbreak member 22. It should be noted that when the cover plate 24 is closed, the position of the retaining plate 241 corresponds to the groove 221 on the topmost windbreak member 22.

[0039] In other words, before closing the cover 24, regardless of the state of the other wind deflectors 22 below, the operator needs to ensure that at least the top wind deflector 22 is closed. When the cover 24 is rotated to the closed position, the retaining plate 241 on its inner surface will descend accordingly and be precisely inserted into the groove 221 of the top wind deflector 22 that is in the closed position.

[0040] By inserting the retaining plate 241 into the groove 221, a locking effect can be achieved on the top wind deflector 22: firstly, it restricts the movement of the wind deflector 22 vertically; secondly, it prevents the wind deflector 22 from rotating around its axis through physical interference, thus firmly locking it in a closed state. For the other wind deflectors 22 in the closed state, the engagement between the protrusion 222 and the groove 221 can lock all the wind deflectors 22 in the closed state, providing sufficient sealing.

[0041] In some embodiments, a first elastic buckle 242 is provided on the cover plate 24, and a first locking hole 123 is provided on the second side wall 122. The first elastic buckle 242 can protrude toward the fan frame assembly 1 and be locked in the first locking hole 123 to lock the cover plate 24, and can retract away from the fan frame assembly 1 and disengage from the first locking hole 123 to unlock the cover plate 24.

[0042] Reference Figure 2 As shown, when the cover plate 24 is rotated to the closed position, pressing the cover plate 24 into place by hand causes the surface of the first elastic latch 242 to be compressed upon contact with the second sidewall 122, forcing the first elastic latch 242 to undergo elastic deformation (such as retracting into the cover plate 24). When the cover plate 24 is fully closed and the first elastic latch 242 moves to a position aligned with the first latch hole 123, the elastic restoring force drives the first elastic latch 242 to pop out toward the second sidewall 122 in the fan frame assembly 1 (i.e., toward the first latch hole 123) and engage with the first latch hole 123. At this time, the cover plate 24 is securely locked in the closed position.

[0043] When it is necessary to open the cover 24, simply press the first elastic latch 242 directly by hand, applying a force that moves it away from the second sidewall 122 in the fan frame assembly 1 (i.e., away from the first latch hole 123) and retracts it, forcing the first elastic latch 242 to disengage from the first latch hole 123. Alternatively, the cover 24 can be flipped over, allowing the first elastic latch 242 to disengage from the first latch hole 123 under the pressure of the first elastic latch 242 and the first latch hole 123. After releasing the lock between the two, the cover 24 can be easily opened for top operation. It should be noted that unlocking the cover 24 does not change the existing state of any wind deflector 22.

[0044] In some embodiments, refer to Figure 6 As shown, a support portion 243 is provided on the cover plate 24, and a support step 124 is provided on the second side wall 122. When the cover plate 24 is placed on the top of the wire passage gap 12, the support portion 243 is supported on the support step 124.

[0045] Specifically, the support part 243 is located on the inner side of the cover plate 24 and below its free edge (i.e. the side where the first elastic buckle 242 is installed). The support part 243 can be a separately installed block or a boss, folded edge or rib formed by stamping and bending the entire cover plate 24, and its bottom surface forms a flat bearing surface.

[0046] On the second side wall 122, at a horizontal height corresponding to the position of the support part 243 when the cover plate 24 is closed, a support step 124 is provided. The support step 124 can be a small platform that is fixedly connected, or it can be a stepped structure that is stamped or integrally formed directly on the second side wall 122.

[0047] When the cover 24 is closed and locked, the bottom surface of the support 243 will stably support (i.e., overlap or sit on) the upper surface of the support step 124. Understandably, the support step 124, as a load-bearing support at the free end of the cover 24, effectively distributes the weight of the cover 24 and any possible minor external loads, preventing these forces from being entirely borne by the rotating shaft (or hinge shaft, pin shaft, or hinge chain shaft) and the first elastic latch 242, thus greatly improving the overall mechanical strength and long-term reliability of the cover 24. Secondly, the support step 124 also provides a precise vertical positioning reference for the cover 24, ensuring that the latch 241 on the cover 24 accurately aligns with the groove 221 of the top windbreak 22 each time it is closed, thereby achieving reliable local locking and ensuring that the sealing effect of the top will not fail due to the sinking or misalignment of the cover 24, even under long-term use or vibration conditions.

[0048] In some embodiments, refer to Figure 3 and Figure 6 As shown, the wind deflector assembly 2 also includes a sliding switch 25, which is slidably disposed on the second side wall 122. The sliding switch 25 has a second elastic buckle, and the second side wall 122 has a second locking hole 125. The second elastic buckle can protrude towards the fan frame assembly 1 and engage in the second locking hole 125, thereby fixing the position of the sliding switch 25 relative to the fan frame assembly 1, and allowing it to retract away from the fan frame assembly 1 and disengage from the second locking hole 125, facilitating the sliding switch 25 to slide relative to the fan frame assembly 1. When the second elastic buckle is engaged in the second locking hole 125, the wind deflector 22 and the sliding switch 25 abut and lock together, ensuring that the wind deflector 22 remains in a closed state.

[0049] When the slide switch 25 is pushed by hand, the surface of the second elastic latch is compressed upon contact with the second sidewall 122, forcing the second elastic latch to undergo elastic deformation (e.g., retracting towards the slide switch 25). When the slide switch 25 moves to the closed position, and the second elastic latch moves to a position aligned with the second locking hole 125, the elastic restoring force drives the second elastic latch to pop out towards the second sidewall 122 in the fan frame assembly 1 (i.e., towards the second locking hole 125) and lock into the second locking hole 125. At this time, the slide switch 25 is firmly locked in the closed position and can abut against the wind deflector 22 to fix the position of the wind deflector 22.

[0050] When it is necessary to rotate the wind deflector 22, simply press the second elastic latch directly by hand, applying a force that moves it away from the second sidewall 122 in the fan frame assembly 1 (i.e., away from the second locking hole 125) and retracts it, forcing the second elastic latch to disengage from the second locking hole 125. Alternatively, the sliding switch 25 can be pushed directly, so that the second elastic latch can disengage from the second locking hole 125 under the squeezing action of the second elastic latch and the second locking hole 125. After releasing the lock between the two, the sliding switch 25 can be easily pushed to disengage from the wind deflector 22, facilitating the rotation of the wind deflector 22 and avoiding cable routing.

[0051] Understandably, the sliding switch 25 will only come into contact with or interfere with the free ends of the wind deflectors 22 that are in the closed state. For wind deflectors 22 that are in the open state due to cable routing, their free ends are retracted away from the second sidewall 122 and will not be touched by the sliding switch 25. Therefore, the sliding switch 25 can selectively lock the wind deflectors 22, that is, it only locks the wind deflectors 22 that are currently in the closed state, preventing them from rotating in the opening direction, while having no effect on the already open wind deflectors 22, preserving their open state. With this configuration, even if some cables remain in the cable routing gap 12 during server operation, the wind deflectors 22 in other wireless areas can be securely locked.

[0052] In some embodiments, refer to Figure 6 As shown, the sliding switch 25 includes a sliding plate 251 and an abutment plate 252 disposed on the sliding plate 251, and the abutment plate 252 and the sliding plate 251 are connected at an angle. A sliding groove is provided on the second side wall 122, and the sliding plate 251 slides and engages with the sliding groove along the arrangement direction of the fan frame assembly 1.

[0053] In practice, the sliding plate 251 can be a flat, elongated plate with its top and bottom edges forming guide edges, which cooperate with the additional sliding groove on the second side wall 122, so that the sliding plate 251 can slide smoothly along one direction (usually the horizontal direction, i.e. the arrangement direction of the fan frame assembly 1) to avoid tilting or falling off.

[0054] Furthermore, the abutment plate 252 and the sliding plate 251 are fixedly connected or integrally formed, and the two are connected at an angle. The side of the abutment plate 252 facing the gap 12 is formed as an abutment surface for contacting and sealing the windproof member 22 in the closed state. Specifically, the abutment plate 252 and the sliding plate 251 can be connected at a 90-degree angle.

[0055] The flow-blocking device provided in this application has the following advantages: (1) Following the principle of decentralization, the integral wind baffle is changed into a split wind baffle 22, which realizes the diversity of the form of the flow blocking device. That is, each wind baffle 22 can be opened or closed independently (adjacent wind baffles 22 can be stacked flat or cross each other), which meets the compatibility requirements under various cable configurations.

[0056] (2) The top surface of the wind deflector 22 is provided with a groove 221 and the bottom surface of the wind deflector 22 is provided with a protrusion 222. The wind deflector 22 presents a Y-shaped wind deflector structure. Multiple wind deflectors 22 are stacked and assembled in sequence to achieve the overall sealing effect of the flow blocking device.
