Server fan assembly, server and fan assembly control method

Abstract

This application discloses a server fan device, a server, and a fan device control method, relating to the technical field of servers. The method involves setting a fan module on the upper part of the server's heat-conducting plate, and setting an adjustment groove and a rotating rod on the fan module's shaft for connecting and driving the fan blades. The fan blades are fixedly connected to the rotating rod. A transmission unit drives a gear to rotate, which in turn drives the coaxially connected rotating rod to rotate within the adjustment groove, thereby adjusting the fan blades to different angles around the axis of the rotating rod. This solves the problem of the inability to adjust the fan blade angle in existing fan modules, achieving control over the airflow generated by the fan. Simultaneously, a shock-absorbing structure is set at the bottom of the fan to reduce the impact of vibrations generated during fan operation on other components.

Description

Technical Field

[0001] This application relates to the technical field of servers, specifically to a server fan device, a server, and a fan device control method. Background Technology

[0002] Servers generate a lot of heat during long-term high-load operation. The fan device in the server generates airflow to expel this heat, thereby keeping the internal temperature of the server within a safe range, preventing the server from overheating, avoiding server performance degradation, system crashes, or even hardware damage, and ensuring the normal operation of the server.

[0003] In some related technologies, when the temperature inside the server changes, the temperature is usually controlled by turning on the fan or adjusting the speed. However, the fan blade angles in existing servers are fixed, meaning that the airflow generated by each fan blade rotating once is fixed and cannot be adjusted. Furthermore, during the fan's rotation, since the fan is connected to the server chassis, and the chassis is connected to other components, the vibration of the fan during operation can interfere with the normal operation of other components. Summary of the Invention

[0004] This application provides a server fan device, a server, and a fan device control method. By setting the blade angle of the fan device in this application to adjust according to the temperature inside the server, the air volume generated by the fan can be controlled. At the same time, by setting a shock-absorbing structure at the bottom of the fan, the impact of the vibration generated during the operation of the fan on other components is reduced. This at least solves the problems of the inability to adjust the fan blade angle and the interference of the fan operation on other components in the related technology.

[0005] In a first aspect, this application provides a server fan device, including a heat-conducting plate connected to a server, a fan module disposed on the heat-conducting plate, the fan module including a drive shaft, a mounting sleeve sleeved on the drive shaft, and an adjustment groove disposed on the outer periphery of the mounting sleeve, a rotating rod rotatably mounted in the adjustment groove, the other end of the rotating rod being fixedly connected to a fan blade, a gear sleeved on the rotating rod, and the gear being connected to a transmission part, so as to realize that the fan blade is driven by the transmission part to adjust to a preset angle around the axis of the rotating rod.

[0006] In one specific embodiment, the transmission unit includes a drive assembly connected to the mounting sleeve and a sliding plate slidably mounted on the mounting sleeve. One side of the sliding plate is connected to the drive assembly, and the other side is connected to a rack, which meshes with a gear.

[0007] In one specific embodiment, a limiting groove is provided on the side wall of the mounting sleeve, and a limiting rod is connected to the side of the sliding plate near the mounting sleeve. The end of the limiting rod away from the sliding plate is slidably connected in the limiting groove.

[0008] In one specific embodiment, the system also includes a controller and a temperature sensor. The controller is communicatively connected to the drive unit, transmission unit, and temperature sensor of the fan module. The temperature sensor is used to collect the real-time temperature inside the server and transmit it to the controller.

[0009] In one specific embodiment, the heat-conducting plate is provided with a cavity for containing coolant, the fan module is provided with a fan housing, and a first damping component and a second damping component are provided between the fan housing and the cavity.

[0010] In one specific embodiment, the first damping component includes a first extension tube, a first piston, and a support rod. The first extension tube is disposed on the top side of the receiving cavity near the fan module. The first extension tube communicates with the receiving cavity and is filled with coolant. The first piston is slidably connected inside the first extension tube. One side of the first piston is in contact with the coolant, and the other side is connected to the support rod. The support rod extends to the fan housing.

[0011] The second damping assembly includes a second extension tube, a second piston, and a cover plate fixedly connected to the end of the second extension tube. The second extension tube is located on the top side of the receiving cavity near the fan module. The second extension tube communicates with the receiving cavity and is filled with coolant. The second piston is slidably connected inside the second extension tube. One side of the second piston is in contact with the coolant, and the other side is connected to a buffer spring. The other end of the buffer spring is connected to an adjusting block. An adjusting rod is provided on the other side of the adjusting block. One end of the adjusting rod is rotatably connected to the adjusting block, and the other end is threadedly connected to the cover plate and penetrates the cover plate to contact the fan housing.

[0012] In one specific embodiment, a mounting plate is fixedly connected to the side wall of the heat-conducting plate, and mounting holes are provided on the mounting plate.

[0013] In one specific embodiment, a heat sink is connected to the top of the heat conduction plate. The heat sink is S-shaped, and the air outlet of the fan module faces the heat sink.

[0014] Secondly, this application also provides a server equipped with the server fan device described above.

[0015] Thirdly, this application also provides a fan device control method, applied to the above-mentioned server or the above-mentioned server fan device, wherein the server heat dissipation device includes a fan module, a drive unit, fan blades, a heat sink, a controller, a temperature sensor, and a transmission unit installed on one side of the server, and the method includes:

[0016] The real-time temperature inside the server is collected by a temperature sensor and transmitted to the controller. When the difference between the real-time temperature and the preset temperature exceeds the preset threshold, the controller controls the transmission unit to drive the fan blades to rotate to the preset angle, and drives the fan module to run to dissipate heat from the heat sink.

[0017] This application solves the problem of the inability to adjust the fan blade angle in existing fan modules by setting a fan module on the upper part of the server's heat-conducting plate, and setting an adjustment groove and a rotating rod on the fan module for connecting and driving the fan blade rotation shaft. The fan blade is fixedly connected to the rotating rod, and the power transmission unit drives the gear to rotate. At this time, the gear drives the coaxially connected rotating rod to rotate in the adjustment groove, so that the fan blade can be adjusted to different angles around the axis of the rotating rod. This achieves control over the air volume generated by the fan.

[0018] Meanwhile, a shock-absorbing structure is installed at the bottom of the fan. The first shock-absorbing component has a first extension tube between the fan housing and the heat-conducting plate. The first extension tube stores coolant and a piston is slidably connected to the upper part of the coolant. When the fan vibrates during operation, the vibration is transmitted to the coolant through the piston movement, thereby absorbing the vibration through the coolant. At the same time, the second shock-absorbing component is equipped with an adjusting rod, a piston, and a buffer spring to improve the shock absorption effect and reduce the impact of the vibration generated during fan operation on other components.

[0027] 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.

[0028] Embodiments of this application provide a fan device for a server, such as... Figure 1 and Figure 2As shown, the system includes a heat-conducting plate 1 connected to the server and a fan module 2 mounted on the heat-conducting plate 1. The fan module 2 is mounted on the upper part of the heat-conducting plate 1 via a connector, so that the fan module 2 generates airflow to blow onto the heat-conducting plate 1 to dissipate heat from the server. Specifically, the fan module 2 includes a fan housing 201, a drive unit 205, a drive shaft 202, a mounting sleeve 203, and an adjustment groove 204. The drive unit 205 is mounted on the inner side wall of the fan housing 201. The output end of the drive unit 205 is provided with the drive shaft 202. An annular mounting sleeve 203 is fitted on the drive shaft 202. An adjustment groove 204 is formed on the outer peripheral wall of the mounting sleeve 203. Several adjustment grooves 204 are formed along the outer periphery of the mounting sleeve 203, and the number of adjustment grooves 204 corresponds one-to-one with the fan blades 4. A rotating rod 3 is rotatably installed in the adjusting groove 204. The other end of the rotating rod 3 extends out of the adjusting groove 204 and is fixedly connected to a fan blade 4. A gear 5 is sleeved in the middle of the rotating rod 3. The gear 5 is connected to a transmission part 6. The transmission part 6 is used to drive the gear 5 to rotate so that the fan blade 4 can be adjusted to a preset angle around the axis of the rotating rod 3 through the transmission part 6.

[0029] In one specific embodiment, the device further includes a controller and a temperature sensor. The controller is communicatively connected to the drive unit 205, the transmission unit 6, and the temperature sensor of the fan module 2. The temperature sensor is installed inside the server to collect the real-time temperature inside the server and transmit it to the controller, thereby enabling the controller to obtain the real-time temperature and adjust the angle of the fan blades 4 according to the difference between the real-time temperature and the preset temperature.

[0030] In this embodiment, the fan blade angle refers to the angle between the fan blade 4 and the horizontal plane. When the difference between the real-time temperature and the preset temperature meets the preset threshold, the angle of the fan blade 4 is kept unchanged. When the difference between the real-time temperature and the preset temperature exceeds the preset threshold, the controller controls the transmission unit 6 to work, and the rotating rod 3 rotates to increase the fan blade angle, that is, to increase the angle between the fan blade 4 and the horizontal plane, thereby increasing the air volume generated by the fan blade 4 rotating once at the same fan blade speed.

[0031] In one specific embodiment, when the difference between the real-time temperature and the preset temperature meets a preset threshold, the angle of fan blade 4 remains unchanged, and the rotation speed of fan blade 4 is also kept constant. When the difference between the real-time temperature and the preset temperature exceeds the preset threshold, the fan blade angle is increased, and the rotation speed of fan blade 4 is adjusted to a preset first-level rotation speed. The running time for increasing the fan blade angle is recorded. If, within a preset time range, the difference between the real-time temperature and the preset temperature still exceeds the preset threshold, the fan blade angle is further increased, and the rotation speed of fan blade 4 is adjusted to a second-level rotation speed. The value of the first-level rotation speed is less than the value of the second-level rotation speed.

[0032] like Figure 2As shown, the transmission unit 6 includes a drive assembly 601, a sliding plate 602, and a rack 603. The drive assembly 601 is mounted on the side wall of the mounting sleeve 203 via a connector. The sliding plate 602 is annular and is slidably mounted outside the mounting sleeve 203. One side of the sliding plate 602 is connected to the output end of the drive assembly 601, and the other end is connected to the rack 603. Several racks 603 are fixedly connected along the outer periphery of the sliding plate 602. Their installation positions correspond one-to-one with the gears 5 on the rotating rod 3, and the racks 603 mesh with the gears 5 to realize that the drive assembly 601 drives several racks 603 to move in the vertical direction, so that the gears 5 together with the rotating rod 3 rotate around the central axis of the gears 5, thereby realizing the adjustment of the angle of the fan blade 4.

[0033] It should be noted that the drive component 601 in this embodiment includes, but is not limited to, a telescopic rod or a hydraulic cylinder, so as to achieve the adjustment of the angle of the fan blade 4 by driving the drive component 601.

[0034] In one specific embodiment, to ensure the stable sliding of the adjusting sliding plate 602 along the mounting sleeve 203 and reduce the possibility of it deviating or dislodging on the outer periphery of the sliding sleeve, a limiting groove 7 is formed on the side wall of the mounting sleeve 203. A limiting rod 8 is connected to the side of the sliding plate 602 closest to the mounting sleeve 203. The end of the limiting rod 8 away from the sliding plate 602 is slidably connected in the limiting groove 7. The annular sliding plate 602 acts as a limiting support, restricting the sliding path of the sliding plate 602 along the outer side of the mounting sleeve 203 and reducing the deviation of the sliding plate 602 during use.

[0035] like Figure 4 As shown, several heat sinks 9 are fixedly connected to the top of the heat conduction plate 1. The air outlet of the fan module 2 faces the heat sink 9 so as to enhance the heat dissipation effect of the heat sink 9 through the fan module 2. The longitudinal section of the heat sink 9 is set as S-shaped. Several heat sinks 9 are arranged at intervals along the top of the heat conduction plate 1. The S-shaped heat sinks 9 increase the heat dissipation area of ​​the heat dissipation plate, thereby improving the heat dissipation effect.

[0036] It should be noted that the heat-conducting plate 1 in this embodiment is made of aluminum alloy to ensure the heat dissipation efficiency of the aluminum alloy heat-conducting plate 1.

[0037] like Figure 1As shown, the fan module 2 is installed outside the heat-conducting plate 1. When the fan module 2 is running, the vibration generated by the fan module 2 is transmitted to the inside of the server through the fan housing 201, the heat-conducting plate 1, etc., thereby affecting the operation of the components inside the server. In this embodiment, by setting a receiving cavity 10 for containing coolant inside the heat-conducting plate 1, and setting a first damping component 11 and a second damping component 12 between the fan housing 201 and the receiving cavity 10, the vibration generated by the fan module 2 is transmitted to the coolant, and is buffered and absorbed by the first damping component 11 and the second damping component 12, which greatly reduces the impact of fan operation on the server components.

[0038] In this embodiment, the fan housing 201 is square, and at least four first damping components 11 are distributed around the perimeter of the fan housing 201, corresponding to the four corner edges of the fan housing 201. Each first damping component 11 includes a first extension tube 1101 vertically connected to the heat-conducting plate 1, a first piston 1102 slidably connected within the first extension tube 1101, and a support rod 1103 mounted on the upper part of the first piston 1102. The first extension tube 1101 is cylindrical and communicates with the coolant in the cavity 10, allowing the coolant to fill the first extension tube 1101. One side of the first piston 1102 contacts the coolant, and the other side is fixedly connected to the support rod 1103. The top of the support rod 1103 extends to the fan housing 201 and is supported at the bottom of the fan housing 201. This allows the vibration generated by the operation of the fan module 2 to be transmitted to the coolant through piston movement, thereby absorbing the vibration through the coolant.

[0039] It should be noted that a dust plug 13 is also fitted on the top of the first extension tube 1101 in this embodiment.

[0040] Furthermore, a second shock-absorbing component 12 is provided in the middle of the fan housing 201, and the second shock-absorbing component 12 is located in the middle of the two first shock-absorbing components 11. Specifically, the second shock absorption assembly 12 includes a vertically arranged second extension tube 1201, a second piston 1202 slidably connected inside the second extension tube 1201, and a cover plate 1203 fixedly connected to the upper end of the second extension tube 1201. The second extension tube 1201 is located on the top side of the receiving cavity 10 near the fan module 2. The bottom end of the second extension tube 1201 is connected to and filled with coolant in the receiving cavity 10. The second piston 1202 is slidably connected inside the second extension tube 1201. One side of the second piston 1202 is in contact with the coolant, and the other side is connected to a buffer spring 14. The other end of the buffer spring 14 is connected to an adjusting block 15. An adjusting rod 16 is provided on the other side of the adjusting block 15. One end of the adjusting rod 16 is rotatably connected to the adjusting block 15, and the other end is threadedly connected to the cover plate 1203 and passes through the cover plate 1203 to support the bottom of the fan housing 201. The second damping assembly 12 is equipped with an adjusting rod 16, a second piston 1202, and a buffer spring 14 to achieve buffering and absorption, thereby improving the damping effect and reducing the impact of vibrations generated during fan operation on other components.

[0041] It should be noted that when the fan operates, the vibration is transmitted to the buffer spring 14 via the coolant. The buffer spring 14 acts as a shock absorber, and the coolant also absorbs the reaction force generated by the buffer spring 14, further enhancing the shock absorption effect. The heat generated inside the server is transferred to the coolant in the receiving cavity 10 via the heat conduction plate 1. The coolant then transfers the heat to the heat sink 9, and the airflow generated by the rotating fan blades 4 blows onto the heat sink 9 to achieve heat exchange. Furthermore, by setting the adjusting rod 16 to be threadedly connected to the cover plate 1203, the adjusting rod 16 can be rotated clockwise or counterclockwise during actual use to move the adjusting rod 16 up or down, loosening or tightening the buffer spring 14 to adjust its shock absorption performance.

[0042] Furthermore, the arrangement of four first shock-absorbing components 11 can improve the installation stability of the fan housing 201, and the heat sinks 9 are distributed among multiple first shock-absorbing components 11 to enhance the heat dissipation of the server.

[0043] In this embodiment, a sealing sleeve 17 is fitted on the outer wall of the first piston 1102 and the second piston 1202 to increase the sealing effect between the first piston 1102 and the first extension tube 1101, and between the second piston 1202 and the second extension tube 1201, so as to prevent coolant leakage. In addition, the sealing sleeve 17 will also increase the friction between the first piston 1102 and the second piston 1202, further reducing the vibration caused by the fan rotation.

[0044] In one specific embodiment, a mounting plate 18 is fixedly connected to the side wall of the heat-conducting plate 1. Mounting holes 19 are provided on the mounting plate 18, with a plurality of mounting holes 19 arranged along the outer periphery of the mounting plate 18, so that the fan device can be installed to the corresponding position on the server through a connector passing through the mounting holes 19. It should be noted that the connectors in this embodiment include, but are not limited to, one or more of screws, bolts, pins, self-tapping screws, or weak screws.

[0045] Specific implementation process: The fan device is installed outside the server using mounting plate 18, and a connector passes through mounting hole 19 to ensure stable installation. Heat generated during server operation is conducted through heat-conducting plate 1 to the coolant in the receiving cavity 10, achieving heat exchange and thus cooling the server. In this embodiment, by installing the fan device outside the server, there is no need to have through holes for airflow on the server casing, preventing dust from entering the server and thus avoiding dust accumulation affecting the normal operation of internal components.

[0046] During server operation, the real-time temperature of the server is detected by a temperature sensor and transmitted to the controller. When the difference between the real-time temperature and the preset temperature detected by the controller exceeds the preset threshold, the transmission unit 6 is started to operate. That is, the output end of the drive component 601 extends or retracts to drive the sliding plate 602 to move in the vertical direction of the sliding sleeve. The rack 603 moves synchronously with the sliding plate 602 and meshes with the gear 5. This allows the drive component 601 to drive several racks 603 to move in the vertical direction, so that the gear 5 and the rotating rod 3 rotate around the central axis of the gear 5, thereby adjusting the angle of the fan blade 4, that is, adjusting the air volume generated by the fan blade 4 rotating once at the same fan blade speed.

[0047] By setting the adjusting rod 16 to the cover plate 1203 through a threaded connection, the adjusting rod 16 can be rotated clockwise or counterclockwise during actual use to move the adjusting rod 16 up or down, thereby loosening or tightening the buffer spring 14 and adjusting the shock absorption performance of the buffer spring 14. When the fan runs and generates vibration, the vibration force is transmitted to the buffer spring 14 through the coolant, and the buffer spring 14 can play a shock absorption role. At the same time, the coolant will also absorb the reaction force generated by the buffer spring 14, thereby improving the shock absorption effect.

[0048] In one embodiment, this application provides a server, which includes a server fan device as described above. The server fan device includes a heat-conducting plate 1 connected to the server, a fan module 2 disposed on the heat-conducting plate 1, and a drive shaft 202, a mounting sleeve 203 sleeved on the drive shaft 202, and an adjustment groove 204 disposed on the outer periphery of the mounting sleeve 203. A rotating rod 3 is rotatably mounted in the adjustment groove 204, and a fan blade 4 is fixedly connected to the other end of the rotating rod 3. A gear 5 is sleeved on the rotating rod 3, and the gear 5 is connected to a transmission part 6 to realize the adjustment of the fan blade 4 around the axis of the rotating rod 3 to a preset angle through the transmission part 6.

One side of the sliding plate 602 is connected to the drive assembly 601, and the other side is connected to a rack 603, which meshes with the gear 5.

[0050] In one specific embodiment, a limiting groove 7 is provided on the side wall of the mounting sleeve 203, and a limiting rod 8 is connected to the side of the sliding plate 602 near the mounting sleeve 203. The end of the limiting rod 8 away from the sliding plate 602 is slidably connected in the limiting groove 7.

[0051] In one specific embodiment, a controller and a temperature sensor are also included. The controller is communicatively connected to the drive unit 205, the transmission unit 6, and the temperature sensor of the fan module 2. The temperature sensor is used to collect the real-time temperature inside the server and transmit it to the controller.

[0052] In one specific embodiment, the heat-conducting plate 1 is provided with a cavity 10 for containing coolant, the fan module 2 is provided with a fan housing 201, and a first damping component 11 and a second damping component 12 are provided between the fan housing 201 and the cavity 10.

[0053] In one specific embodiment, the first damping component 11 includes a first extension tube 1101, a first piston 1102, and a support rod 1103. The first extension tube 1101 is disposed on the top side of the receiving cavity 10 near the fan module 2.

One side of the first piston 1102 is in contact with the coolant, and the other side is connected to the support rod 1103. The support rod 1103 extends to the fan housing 201.

[0054] The second shock absorption assembly 12 includes a second extension tube 1201, a second piston 1202, and a cover plate 1203 fixedly connected to the end of the second extension tube 1201. The second extension tube 1201 is disposed on the top side of the receiving cavity 10 near the fan module 2.

One side of the second piston 1202 is in contact with the coolant, and the other side is connected to a buffer spring 14. The other end of the buffer spring 14 is connected to an adjusting block 15. An adjusting rod 16 is disposed on the other side of the adjusting block 15. One end of the adjusting rod 16 is rotatably connected to the adjusting block 15, and the other end is threadedly connected to the cover plate 1203 and penetrates the cover plate 1203 to contact the fan housing 201.

[0059] Specifically, in this embodiment, the angle of the fan blade 4 refers to the angle between the fan blade 4 and the horizontal plane. When the difference between the real-time temperature and the preset temperature meets the preset threshold, the angle of the fan blade 4 is kept unchanged. When the difference between the real-time temperature and the preset temperature exceeds the preset threshold, the transmission unit 6 is controlled to work, and the rotating rod 3 is rotated to increase the angle of the fan blade 4, that is, to increase the angle between the fan blade 4 and the horizontal plane, thereby increasing the air volume generated by the fan blade 4 rotating once at the same fan blade speed.
