[0027] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0028] The embodiment of the present application provides a fan device for a server, such as Figure 1 and Figure 2As shown, it includes a heat conducting plate 1 connected to the server, and a fan module 2 installed on the heat conducting plate 1, wherein the fan module 2 is installed on the upper part of the heat conducting plate 1 through a connecting piece, so that the fan module 2 generates an airflow to blow toward the heat conducting plate 1 to achieve heat dissipation of the server. Specifically, the fan module 2 includes a fan housing 201, a driving part 205, a driving shaft 202, a mounting sleeve 203, and an adjustment slot 204. The driving part 205 is installed on the inner wall of the fan housing 201, and the output end of the driving part 205 is provided with a driving shaft 202. The driving shaft 202 is sleeved with an annular mounting sleeve 203, and the outer peripheral wall of the mounting sleeve 203 is provided with an adjustment slot 204. A plurality of adjustment slots 204 are provided along the outer periphery of the mounting sleeve 203, and the number of the adjustment slots 204 corresponds to the number of the fan blades 4. A rotating rod 3 is rotatably installed in the adjustment slot 204, the other end of the rotating rod 3 extends out of the adjustment slot 204 and is fixedly connected with a fan blade 4, a gear 5 is sleeved on the middle part of the rotating rod 3, the gear 5 is connected to a transmission part 6, and the transmission part 6 is used to drive the gear 5 to rotate so as to drive the fan blade 4 to adjust to a preset angle around the axial direction of the rotating rod 3 through the transmission part 6.

[0029] In a specific embodiment, the device also includes a controller and a temperature sensor. The controller is communicatively connected with the driving part 205, the transmission part 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, so that the real-time temperature can be obtained through the controller, and the angle of the fan blade 4 can be adjusted 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 transmission part 6 is controlled by the controller to rotate the rotating rod 3 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 one circle at the same fan blade speed.

[0031] In a specific embodiment, 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, and the speed of the fan blade 4 is controlled unchanged; when the difference between the real-time temperature and the preset temperature exceeds the preset threshold, the angle of the fan blade is increased, and the speed of the fan blade 4 is controlled to be adjusted to the preset first-level speed; and the operation time of increasing the angle of the fan blade is recorded. When it is detected that the difference between the real-time temperature and the preset temperature still exceeds the preset threshold within the preset time range, the angle of the fan blade is continued to be increased, and the speed of the fan blade 4 is controlled to be adjusted to the second-level speed. The value of the first-level speed is less than the value of the second-level speed.

[0032] like Figure 2As shown, the transmission part 6 includes a driving component 601, a sliding plate 602 and a rack 603. The driving component 601 is installed on the side wall of the mounting sleeve 203 through a connecting piece. The sliding plate 602 is annular, and the sliding sleeve is arranged outside the mounting sleeve 203. One side of the sliding plate 602 is connected to the output end of the driving component 601, and the other end is connected to the rack 603. There are several racks 603 fixedly connected along the outer periphery of the sliding plate 602, and their installation positions correspond one by one to the gears 5 on the rotating rod 3, and the racks 603 are meshed with the gears 5 to realize that the driving component 601 drives the several racks 603 to move in the vertical direction, so that the gears 5 rotate together with the rotating rod 3 around the central axis direction of the gears 5, thereby realizing the adjustment of the angle of the fan blades 4.

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

[0034] In a specific embodiment, in order to ensure that the adjustable sliding plate 602 slides stably along the mounting sleeve 203 and reduce the possibility of deflection or disengagement of the sliding plate 602 from the outer periphery of the sliding sleeve, a limiting sliding groove 7 is provided on the side wall of the mounting sleeve 203, a limiting rod 8 is connected to the side of the sliding plate 602 close to the mounting sleeve 203, and an end of the limiting rod 8 away from the sliding plate 602 is slidably connected in the limiting sliding groove 7, so that the annular sliding plate 602 plays the role of limiting support, forms a limit to the sliding path of the sliding plate 602 along the outer side of the mounting sleeve 203, and reduces the displacement of the sliding plate 602 during use.

[0035] like Figure 4 As shown, a plurality of heat sinks 9 are fixedly connected to the top of the heat conducting plate 1, and the air outlet of the fan module 2 faces the heat sink 9 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 to be S-shaped, and a plurality of heat sinks 9 are arranged at intervals along the top of the heat conducting plate 1, and the S-shaped heat sink 9 increases the heat dissipation area of ​​the heat sink, 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 material to ensure the heat dissipation efficiency of the heat conducting plate 1 made of aluminum alloy material.

[0037] like Figure 1As shown, the fan module 2 is installed outside the heat conducting plate 1. When the fan module 2 is in operation, the vibration generated by the fan module 2 will be 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 in the server. In this embodiment, a receiving chamber 10 for receiving coolant is provided in the heat conducting plate 1, and a first shock absorbing assembly 11 and a second shock absorbing assembly 12 are provided between the fan housing 201 and the receiving chamber 10, so as to transmit the vibration generated by the fan module 2 to the coolant, and to buffer and absorb the vibration through the first shock absorbing assembly 11 and the second shock absorbing assembly 12, thereby greatly reducing the impact of the fan operation on the server components.

[0038] The fan housing 201 in this embodiment is square, wherein at least four first damping assemblies 11 are distributed along the four sides of the fan housing 201, and the four first damping assemblies 11 are distributed correspondingly at the four corner edges of the fan housing 201. The first damping assembly 11 includes a first extension tube 1101 vertically connected to the heat conducting plate 1, a first piston 1102 slidably connected in the first extension tube 1101, and a support rod 1103 installed on the upper part of the first piston 1102. The first extension tube 1101 is cylindrical and is also connected to the coolant in the accommodating chamber 10, so that the coolant fills the first extension tube 1101; one side of the first piston 1102 is in contact with the coolant, and the other side is fixedly connected to the support rod 1103, and the top of the support rod 1103 extends to the fan housing 201 and is supported at the bottom of the fan housing 201. In this way, the vibration generated by the operation of the fan module 2 is transmitted to the coolant through the piston movement, so that the vibration is absorbed by the coolant.

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

[0040] Furthermore, a second shock absorbing assembly 12 is disposed in the middle of the fan housing 201 , and the second shock absorbing assembly 12 is located in the middle of the two first shock absorbing assemblies 11 . Specifically, the second shock absorbing assembly 12 includes a vertically arranged second extension tube 1201, a second piston 1202 slidably connected in 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 arranged on the top side of the accommodating chamber 10 close to the fan module 2. The bottom end of the second extension tube 1201 is connected to the coolant in the accommodating chamber 10 and is filled with coolant. The second piston 1202 is slidably connected in 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 the buffer spring 14. The other end of the buffer spring 14 is connected to the adjusting block 15. The other side of the adjusting block 15 is provided with an adjusting rod 16. 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 be supported at the bottom of the fan casing 201. The second damping assembly 12 is provided with the adjusting rod 16, the second piston 1202 and the buffer spring 14 to realize the buffering and absorbing effects, so as to enhance the damping effect and reduce the influence of the vibration generated during the operation of the fan on other components.

[0041] It should be noted that when the fan is running and generates vibration, the vibration force is transmitted to the buffer spring 14 via the coolant, and the buffer spring 14 can play a shock-absorbing effect. At the same time, the coolant will also absorb the reaction force generated by the buffer spring 14, thereby improving the shock-absorbing effect. The heat generated inside the server is transmitted to the coolant in the accommodating cavity 10 via the heat conducting plate 1, and the coolant transfers the heat to the heat sink 9. The airflow generated by the rotation of the fan blades 4 blows toward the heat sink 9 to achieve heat exchange. In addition, by setting a threaded connection between the adjustment rod 16 and the cover plate 1203, the adjustment rod 16 can be rotated clockwise or counterclockwise during actual use to move the adjustment rod 16 upward or downward, loosen or tighten the buffer spring 14, and adjust the shock-absorbing performance of the buffer spring 14.

[0042] Furthermore, the provision 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 the multiple first shock absorbing components 11 to enhance the heat dissipation of the server.

[0043] In this embodiment, a sealing sleeve 17 is provided 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 the sealing effect between the second piston 1202 and the second extension tube 1201, to avoid leakage of coolant; and the setting of 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 rotation of the fan.

[0044] In a specific embodiment, a mounting plate 18 is fixedly connected to the side wall of the heat conducting plate 1, and a mounting hole 19 is provided on the mounting plate 18. A plurality of mounting holes 19 are provided along the outer circumference of the mounting plate 18, so that the fan device can be installed to a corresponding position on the server by passing the connecting member through the mounting hole 19. It should be noted that the connecting member in this embodiment includes but is not limited to one or more of screws, bolts, pins, self-tapping screws or weak nails.

[0045] Specific implementation process: The fan device is installed outside the server through the mounting plate 18, and the mounting hole 19 is penetrated by the connector to stably install the fan device. The heat generated during the operation of the server is transferred to the coolant in the accommodating cavity 10 through the heat conducting plate 1 to achieve heat exchange, thereby cooling and dissipating the heat of the server. In this embodiment, by installing the fan device outside the server, it is not necessary to open a through hole for air flow on the server housing, preventing dust from entering the server, thereby preventing the accumulation of dust from affecting the normal operation of the internal components of the server.

[0046] During the operation of the server, the real-time temperature of the server is detected by a temperature sensor and transmitted to the controller. When the controller detects that the difference between the real-time temperature and the preset temperature exceeds a preset threshold, the transmission part 6 is controlled to start running, that is, the output end of the driving component 601 is extended or retracted to drive the sliding plate 602 to move in the vertical direction of the sliding sleeve, and the rack 603 moves synchronously with the sliding plate 602. The rack 603 is meshed with the gear 5 to achieve driving of several racks 603 in the vertical direction through the driving component 601, so that the gear 5 rotates together with the rotating rod 3 around the central axis of the gear 5, so as to adjust the angle of the fan blade 4, that is, the adjustment of the air volume generated by one rotation of the fan blade 4 at the same fan blade 4 speed.

[0047] By setting a threaded connection between the adjusting rod 16 and the cover plate 1203, during actual use, the adjusting rod 16 can be rotated clockwise or counterclockwise to move the adjusting rod 16 upward or downward, thereby loosening or tightening the buffer spring 14 to adjust the shock absorbing performance of the buffer spring 14; when the fan is running and vibrates, the vibration force is transmitted to the buffer spring 14 through the coolant, and the buffer spring 14 can achieve a shock absorbing effect. At the same time, the coolant will also absorb the reaction force generated by the buffer spring 14, thereby improving the shock absorbing effect.
