Description

Technical Field

[0001] This utility model relates to the field of server fan technology, and in particular to a fan frame device and its server. Background Technology

[0002] Servers are now ubiquitous, and due to their frequent handling of massive amounts of data and high-speed computations, the internal components of the server, such as the CPU, PCIe cards, and memory units, generate heat during these processes. This heat must be dissipated through airflow from internal fans to prevent overheating, which could lead to system instability, reduced processing speed, or even crashes. Generally, to comply with safety regulations, fixed air vents are installed to prevent users from inserting their hands into the fan vents and injuring themselves when performing maintenance on the server by removing the top cover. However, during server operation, a full-scale air vent directly obstructing the airflow can significantly reduce the airflow, even causing poor cooling efficiency. This issue warrants careful study and improvement by industry professionals. Utility Model Content

[0032] Before the utility model is described in detail, it should be noted that in the following description, similar elements are denoted by the same number.

[0033] Reference Figures 1 to 6The utility model provides a fan frame device 1 for combining on a fan device 80 in a server 90. The server 90 includes a casing 91, and a detachable cover 92 arranged on the casing 91. The fan device 80 is arranged in the casing 91 and includes a fan casing 81 and a fan unit 82 arranged in the fan casing 81. The fan casing 81 has an air outlet 811. The fan unit 82 has a fan 821 arranged in the fan casing 81, a fan shaft 822 for driving the fan 821 to rotate, and a rotating piece 823 arranged on the fan 821 and corresponding to the fan shaft 822 and capable of being driven to rotate synchronously by the fan shaft 822. The fan frame device 1 includes a frame 2 detachably combined with the fan casing 81 of the fan device 80 and corresponding to the air outlet 811, a driving unit 3, a fan-shaped grille unit 4, and a linkage frame unit 5.

[0034] The frame 2 includes a combination port 21. The driving unit 3 includes a bearing module 31 combined in the combination port 21 of the frame 2, a driving module 32 arranged on a side of the frame 2 close to the fan device 80 and capable of being driven to rotate by the rotating piece 823 of the fan unit 82, and a rotating shaft module 35 arranged on the driving module 32 and extending from the driving module 32 to the combination port 21 of the frame 2 and penetrating through the bearing module 31 to pass through the combination port 21.

[0035] The driving module 32 has a starting frame 33 arranged on a side of the frame 2 close to the fan device 80, and a driver 34 arranged on the starting frame 33 and capable of being driven to rotate synchronously by the rotating piece 823 under the control of the starting frame 33. The starting frame 33 has a body 331 combined with the driver 34 and capable of being driven to rotate by the driver 34, and a control part 332 arranged around the periphery of the body 331 and extending away from the body 331. The rotating shaft module 35 is arranged on the driver 34 and penetrates through the body 331 of the starting frame 33 and the bearing module 31. The driver 34 is arranged on a side of the body 331. The control part 332 can drive the body 331 to move the driver 34 between a preset position and a maintenance position. When the driver 34 is in the preset position, the driver 34 is in contact with the rotating piece 823, and the rotating piece 823 rotates to generate friction with the driver 34, which synchronously drives the driver 34 to rotate to make the rotating shaft module 35 rotate synchronously. When the driver 34 is in the maintenance position, the driver 34 is away from the rotating piece 823, and the driver 34 does not rotate.

[0036] The fan-shaped air baffle unit 4 is arranged on the end of the rotating shaft module 35 away from the driving module 32 and corresponds to the air outlet 811, and can be driven to rotate by the rotating shaft module 35. The fan-shaped air baffle unit 4 and the fan device 80 are located on the opposite sides of the frame 2. The rotating direction of the fan-shaped air baffle unit 4 driven by the rotating shaft module 35 is the same as the rotating direction of the fan 821 of the fan device 80. The fan-shaped air baffle unit 4 and the fan 821 of the fan device 80 rotate in the same direction.

[0037] The linkage frame unit 5 includes an elastic module 51 arranged on the frame 2 and capable of being pressed by the shell cover 92, and an active arm module 52 arranged on the elastic module 51 and extending from the elastic module 51 to the starting frame 33 of the driving module 32, and capable of pushing the control part 332 of the starting frame 33. When the shell cover 92 is covered on the casing 91 and presses the elastic module 51 to link the active arm module 52 to move in the direction of the body 331 of the starting frame 33, and the active arm module 52 does not push the control part 332 of the starting frame 33, at this time, the driver 34 is located at the preset position and drives the rotating shaft module 35 to rotate to synchronously drive the fan-shaped air baffle unit 4 to rotate; when the shell cover 92 is detached from the casing 91 and the elastic module 51 is not pressed, the elastic restoring force of the elastic module 51 links the active arm module 52 to move in the direction away from the body 331 of the starting frame 33, and the active arm module 52 moves to push the control part 332 of the starting frame 33 and pushes the control part 332 in the direction away from the fan unit 82 to drive the body 331 to link the driver 34 to move to the maintenance position.

[0038] When assembling, as long as the shell cover 92 is covered on the casing 91, since the shell cover 92 will press the elastic module 51 and make the elastic module 51 accumulate the elastic restoring force, and make the elastic module 51 link the active arm module 52 to move in the direction of the body 331 of the starting frame 33, and make the active arm module 52 push the control part 332 of the starting frame 33 in the direction away from the fan unit 82 to drive the body 331 to link the driver 34 to move to the maintenance position. Figure 5 Figure 5 ​The ground will not push against the starter 33. At this time, the driver 34 is in the preset position and drives the rotating shaft module 35 to rotate, which in turn drives the fan blade-shaped wind grid unit 4 to rotate. In other words, when the cover 92 is closed and the fan 821 of the fan unit 82 is operating, the driver 34 is located in the preset position, and the friction generated by the rotating blade 823 of the fan unit 82 rotating and rubbing against the driver 34 synchronously drives the driver 34 to rotate, which in turn drives the shaft module 35 to rotate and synchronously drives the fan blade-shaped air grille unit 4 to rotate. The direction of rotation of the fan blade-shaped air grille unit 4 driven by the shaft module 35 is the same as the direction of rotation of the fan 821 of the fan device 80. That is, the fan blade-shaped air grille unit 4 will rotate synchronously with the fan 821 and rotate in the same direction as the fan 821 of the fan device 80. This allows the airflow generated by the fan 821 to pass through the air outlet 811 and be driven by the rotation of the fan blade-shaped air grille unit 4 to continue to flow, maintaining a high airflow volume and effectively increasing the overall heat dissipation efficiency.

[0039] Relatively speaking, if the cover 92 is removed from the casing 91 for server 90 maintenance, the cover 92 will not press against the elastic module 51, and the elastic module 51 will release its elastic restoring force, causing the elastic module 51 to move the movable arm module 52 away from the body 331 of the launcher 33, and causing the movable arm module 52 to move as... Figure 6 As shown, the actuator 34 is pushed away from the fan unit 82, causing it to move away from the rotating blade 823 of the fan unit 82 and to the maintenance position. At this time, the actuator 34 does not contact the rotating blade 823 and cannot drive the fan blade-shaped air grille unit 4 to rotate, thus causing the air outlet 811 of the fan device 80 to be as shown. Figure 3 The fan blade-shaped air vent unit 4 blocks and shields the airflow, ensuring that during maintenance of the server 90, the user's hand cannot be inserted into the fan housing 81 through the air vent 811, thus avoiding the risk of injury.

[0040] The design of the drive module 32's driver 34, which is driven by the starter bracket 33, is such that the driver 34 is positioned at the preset position. This is achieved by the cover 92 covering the housing 91, which in turn causes the driver 34 to rotate the shaft module 35 and simultaneously rotate the fan blade-shaped air grating unit 4. This allows the airflow generated by the fan 821 to continue flowing through the air outlet 811 and be driven by the rotation of the fan blade-shaped air grating unit 4, maintaining a high airflow rate. This effectively improves the problem of the previous fixed air grating directly blocking the air outlet 811 and reducing the airflow.

[0041] In this embodiment, the elastic module 51 of the linkage frame unit 5 has an elastic member 511 arranged on the frame 2, and a pressing piece 512 arranged on the elastic member 511 and pressed by the cover 92. The movable arm module 52 has a movable arm 521 arranged on the pressing piece 512 of the elastic module 51 and extending from the pressing piece 512 to the starting frame 33 of the driving module 32, and a pushing member 522 arranged on the movable arm 521 and pushing the control portion 332 of the starting frame 33. The pushing member 522 has a guide corner 523. The control portion 332 of the starting frame 33 of the driving module 32 has a guide slope 333 for guiding the guide corner 523 of the pushing member 522. In other words, the linkage frame unit 5 is designed to push the control portion 332 of the starting frame 33 of the driving module 32 through the pushing member 522 of the movable arm module 52, and the pushing member 522 is guided by the guide corner 523 of the pushing member 522 and the guide slope 333 of the control portion 332 of the starting frame 33. When the cover 92 is arranged on the casing 91, the cover 92 presses the pressing piece 512 of the elastic module 51 and the elastic member 511 accumulates the elastic restoring force, and the pressing piece 512 moves the movable arm 521 of the movable arm module 52 to the body 331 of the starting frame 33. The movable arm 521 drives the guide corner 523 of the pushing member 522 to move along the guide slope 333 of the control portion 332 to the body 331, so that the guide corner 523 does not push the control portion 332 of the starting frame 33, as shown in FIG. 10. At this time, the driver 34 is located at the preset position, and the driver 34 drives the rotating shaft module 35 to rotate and synchronously drives the fan-shaped grille unit 4 to rotate. In contrast, when the cover 92 is detached from the casing 91, the cover 92 does not press the pressing piece 512 of the elastic module 51, and the elastic member 511 releases the elastic restoring force, and the pressing piece 512 moves the movable arm 521 of the movable arm module 52 away from the body 331 of the starting frame 33. The movable arm 521 drives the guide corner 523 of the pushing member 522 to move along the guide slope 333 of the control portion 332 away from the body 331, so that the guide corner 523 pushes the control portion 332 of the starting frame 33 away from the fan unit 82, as shown in FIG. 11. At this time, the guide corner 523 pushes the control portion 332 away from the fan unit 82, and drives the body 331 to move the driver 34 to the maintenance position, but is not limited thereto. Figure 6 Figure 5 Figure 6

[0042] ​​​Furthermore, in this embodiment, the frame 2 also includes a base plate 23 near the cover 92. The elastic element 511 of the elastic module 51 of the linkage frame unit 5 is disposed on the base plate 23, and the pressing piece 512 of the elastic module 51 is disposed on the end of the elastic element 511 near the cover 92 and can be pressed by the cover 92. That is, the elastic module 51 of the linkage frame unit 5, through the... Figure 3 The structure shown is provided on the base plate 23 of the frame 2, and it is used to press the pressure plate 512 of the elastic module 51 against the cover 92, so that the elastic member 511 accumulates the elastic restoring force. When the user removes the cover 92 from the housing 91 for maintenance, the elastic restoring force of the elastic member 511 is automatically released, causing the pressure plate 512 to move the movable arm 521 of the movable arm module 52 away from the body 331 of the starter frame 33. During the movement, the movable arm 521 carries... The guide angle portion 523 of the push member 522 moves away from the main body 331 along the guide slope 333 of the control portion 332 until the guide angle portion 523 pushes against the control portion 332 of the starter bracket 33. At this time, the guide angle portion 523 pushes against the control portion 332 away from the fan unit 82, thereby driving the main body 331 and the driver 34 to move to the maintenance position, ensuring that the user's hand cannot be inserted into the fan housing 81 through the air vent 811, thus avoiding the risk of injury. In particular, in this embodiment, the frame 2 also includes an outer frame 24 attached to the fan housing 81, an inner frame 25 spaced apart from the outer frame 24, and a connecting frame 26 connecting the outer frame 24 and the inner frame 25. The base plate 23 is disposed on the outer frame 24 and close to the cover 92. The joint 21 is formed on the inner frame 25, and the outer frame 24, the connecting frame 26, and the inner frame 25 together define a plurality of airflow ports 22. In simple terms, the frame 2 is as follows: Figure 4 The structure shown is composed of the outer frame 24, the inner frame 25 and the connecting frame 26, but is not limited thereto. The airflow port 22 of the frame 2 corresponds to the air outlet 811 of the fan device 80. Therefore, the airflow generated by the fan 821 can pass through the air outlet 811 and flow through the airflow port 22, but is not limited thereto.

[0043] In addition, it is particularly pointed out that in the present embodiment, the fan-shaped air baffle unit 4 has an air baffle cover 41 arranged on one end of the rotating shaft module 35 of the driving module 32 away from the driving module 32, and a plurality of fan blades 42 arranged on the air baffle cover 41 and extending away from the air baffle cover 41. In the preset position, the driver 34 of the driving module 32 is in contact with the rotating piece 823 of the fan unit 82, and the friction generated by the rotating piece 823 rotating and rubbing the driver 34 will simultaneously drive the driver 34 to rotate, so that the rotating shaft module 35 rotates, and the rotating shaft module 35 simultaneously drives the air baffle cover 41 to rotate, thereby driving the fan-shaped air baffle unit 4 to rotate, but not limited to this. In short, the fan-shaped air baffle unit 4 is composed of the air baffle cover 41 and the fan blades 42 as shown in the figure, and the rotating piece 823 of the fan unit 82 drives the driver 34 to rotate, so that the rotating shaft module 35 rotates synchronously and simultaneously drives the fan blades 42 of the fan-shaped air baffle unit 4 to rotate. In other words, the fan blades 42 will rotate synchronously with the fan 821, and the fan-shaped air baffle unit 4 and the fan 821 of the fan device 80 will rotate in the same direction, so that the airflow generated by the fan 821 passes through the air inlet 811 and the airflow port 22 and is continuously driven by the rotation of the fan blades 42 to maintain a high airflow rate, but not limited to this. Figure 4

[0044] It is particularly pointed out that in the present embodiment, the inner frame 25 of the frame 2 has an inner frame body 251, and a plurality of inner frame supports 252 respectively extending from the inner frame body 251 to the connecting frame 26 and respectively connecting the connecting frame 26. The combination port 21 penetrates the inner frame body 251 of the inner frame 25. The inner frame body 251 and the inner frame supports 252 cooperatively define a combination space 253 for accommodating the bearing module 31 of the driving unit 3. The bearing module 31 of the driving unit 3 is arranged on the body 331 of the starting bracket 33 and extends from the body 331 to the direction of the combination space 253 to extend into the combination space 253. The bearing module 31 and the driver 34 of the driving module 32 are located on the two opposite sides of the body 331. That is, the bearing module 31 is combined in the combination space 253 of the inner frame 25, and the rotating shaft module 35 penetrates the bearing module 31 as shown in the figure, so that the rotating shaft module 35 can assist the rotating shaft module 35 to rotate smoothly and improve the efficiency, but not limited to this.
