AI Technical Summary
In electronic devices, the setting of the fan group causes high wind force, and the blinds are difficult to control the lifting amplitude, which may cause the blinds to be stuck and reduce the reliability of heat dissipation.
A fan shutter is designed, using a flexible limit soft wire to connect the baffle. When the fan is not running or fails, the baffle falls down to block the air outlet, and the limit soft wire is bent and stored; when the fan is running, the baffle is raised and the limit soft wire is straightened, so that the baffle forms an integral force to avoid excessive lifting.
It effectively avoids the problem of excessive lifting of blinds when the wind is strong, prevents hot air from flowing back, and improves the heat dissipation reliability of electronic equipment.

Abstract
Description
Technical Field
[0001] The present invention relates to the field of heat exchange technology, and in particular to a fan shutter and a fan. Background Art
[0002] With the development of electronic technology, the computing requirements of electronic devices are constantly increasing, and the overall heat generation is also increasing. Air cooling is widely used in electronic devices as a way to dissipate heat for electronic devices, that is, by configuring fans for electronic devices, the heat generated in the electronic devices is removed by their rotation.
[0003] In some application scenarios of electronic equipment, such as servers in data centers, switching equipment deployed by operators, etc., long-term uninterrupted operation is required, and electronic equipment will be affected by the ambient temperature. When a fan fails, in order to prevent the hot air in the environment from flowing back into the electronic equipment, it is necessary to set an anti-backflow mechanism for the fan, such as setting an anti-backflow baffle on the air outlet side of the fan to form a louver structure. When the fan is operating normally, the louver is blown up so that an air path can be formed in the electronic equipment. When the fan fails, the louver falls down to block the air outlet to prevent the hot air from being re-sucked into the electronic equipment. However, due to the setting of the fan group in the electronic equipment, the wind force is relatively large, which makes it difficult to control the tilting amplitude of the louver when the louver is blown up by the fan. In some cases, the louver may be stuck due to excessive tilting amplitude and cannot be restored to shield the fan, reducing the reliability of heat dissipation of the electronic equipment.

[0034] The present application provides a fan shutter 100, such as Figure 1 As shown, including:
[0035] Frame 1;
[0036] Connecting rods 2 are fixed to two opposite sides 10 of the frame 1;
[0037] A baffle 3 is rotatably disposed on the connecting rod 2;
[0038] The limiting soft wire 4 is arranged on the adjacent baffle 3 .
[0039] The frame 1 may be formed by four sides, including two side sides 10 , an upper side side 11 and a lower side side 12 , and the four sides surround the hollow structure.
[0040] A plurality of connecting rods 2 are contained in the frame 1, and the connecting rods 2 are fixed between the side edges in sequence from top to bottom, and the fixing method can be riveting, welding, screwing, etc., without limitation. Each connecting rod 2 is spaced a certain distance apart, and the distance between the intervals can be nearly equidistant.
[0041] One or more baffles 3 are rotatably arranged on each connecting rod 2, and one baffle 3 is taken as an example. The baffle 3 can be arranged on the connecting rod 2 by penetration or clamping, and the baffle 3 can rotate with the connecting rod 2 as an axis.
[0042] When the fan 200 is running, the wind blows in the direction indicated by the arrow, the baffle 3 is lifted up under the action of the wind, and the wind blows out of the electronic device normally. When the fan is not running or fails, the baffle 3, such as Figure 2 As shown, the fan's air outlet is covered to prevent hot air from flowing back. Figure 2 (A) shows the situation where the baffle 3 (3A-3C) falls down, Figure 2 (B) shows a state where the flap 3 (3A-3C) is lifted up.
[0043] Optionally, the baffle 3, such as Figure 1 As shown, including:
[0044] a sheet body 30; and
[0045] The sleeve 31 is connected to the sheet body 30 , and the sleeve 31 is passed through the connecting rod 2 .
[0046] On one baffle 3 , the number of the sleeves 31 may be one or more. When there is only one sleeve 31 , the sleeve 31 may be located in the middle of the connecting rod 2 .
[0047] In order to further improve the connection reliability between the blocking piece 3 and the connecting rod 2 , optionally, a plurality of sleeves 31 are provided in the blocking piece 3 , and the plurality of sleeves 31 are penetrated through the connecting rod 2 at intervals.
[0048] By providing a plurality of sleeves 31 that are intermittently penetrated through the connecting rod 2 , the connecting rod 2 and the blocking piece 3 can maintain smooth rotation and improve the connection reliability between the connecting rod 2 and the blocking piece 3 .
[0049] In order to prevent the blocking piece 3 from shaking, optionally, the plurality of sleeves 31 are at least arranged near two side edges 10 of the frame body 1 that are arranged opposite to each other.
[0050] When the number of sleeves 31 is small, the size is small, or the positions where the sleeves 31 are inserted into the connecting rod 2 are relatively concentrated, the wind blowing the baffle 3 may cause a certain vibration on the side where the sleeve 31 is not set. When the fan runs for a long time, the sheet body 30 may bend or curl.
[0051] Therefore, on the baffle 3, by arranging the sleeves 31 more evenly, when there are several sleeves 31, some of the sleeves 31 (for example, two) are respectively inserted into the positions of two oppositely arranged side edges 10 close to the frame 1 to avoid bending and curling caused by vibration, so that the fan shutter 100 can have higher reliability.
[0052] The limit wire 4 is arranged on the adjacent baffle 3. Figure 1 , 2 In the figure, the baffle 3 at the top can be considered as the baffle 3A of the previous level, the baffle 3 at the middle can be considered as the baffle 3B of the current level, and the baffle 3 at the bottom can be considered as the baffle 3C of the next level. It can be seen that the adjacent baffles 3 are connected by the limit wire 4. The connection method can be that each two adjacent baffles 3 are connected by the limit wire 4, for example, Figure 2 As shown, the baffle 3A of the previous level is connected to the baffle 3B of the current level, and the baffle 3B of the current level is connected to the baffle 3C of the next level. Alternatively, the baffle 3A of the previous level is connected to the baffle 3B of the current level, and the baffle 3C of the next level is connected to the baffle of the next level. The connection method between the limit wire 4 and the baffle 3 is not limited to this, and can be set according to actual needs. For example, one limit wire 4 can connect three or more baffles 3, or after two baffles 3 are connected by the limit wire 4, one baffle 3 is left unconnected to the limit wire 4, and the two baffles 3 of the next level are connected by another limit wire 4, and so on.
[0053] Optional, such as Figure 2 As shown, the limit wire 4 is passed through the through hole 32 opened on the blocking piece 3.
[0054] By providing the through hole 32, the limiter cord 4 can be conveniently and quickly fixed to the baffle 3, thereby improving the preparation efficiency of the fan shutter 100 with the limiter cord 4. In addition, after passing through the through hole 32, the limiter cord 4 can be fixed to the baffle 3 by bolting, connecting member clamping, etc., which can be set according to actual needs without limitation.
[0055] In order to improve the lifting efficiency of the baffle 3, Figure 1 As shown, optionally, the limit soft wire 4 is arranged at a position of the blocking piece 3 close to the two side edges 10 of the frame 1 .
[0056] Compared with setting the limiting soft wire 4 in the middle of the baffle 3, setting the limiting soft wire 4 at the position of the baffle 3 close to the two side edges 10 of the frame 1 can make the baffle 3 evenly tilt under the action of wind force, avoid the obstruction of air volume caused by the tilting of one side of the baffle 3, and further improve the heat dissipation efficiency of the fan shutter 100.
[0057] Optional, such as Figure 1 As shown, the limit soft wires 4 are cascaded from top to bottom on adjacent baffles 3 .
[0058] By cascading the limiting soft wire 4 to the adjacent baffles 3 from top to bottom, each baffle 3 can be evenly controlled by the wind force, avoiding the problem of the baffle 3 being unable to tilt up due to uneven force, thereby further improving the heat dissipation efficiency of the fan shutter 100.
[0059] Optional, such as Figure 1 , 2 As shown, in the direction from top to bottom, on the baffle 3A of the previous level, the limiting soft wire 4 is set at a position close to the connecting rod 2 through which the baffle 3A of the previous level is penetrated, and on the baffle 3B of this level, the limiting soft wire 4 is set at a position away from the connecting rod 2 through which the baffle 3B of this level is penetrated.
[0060] Through the above-mentioned setting method, the limit wire 4 can be set to a smaller size to avoid the limit wire 4 being too long and stuck by the baffle 3 when the baffle 3 is blown up and dropped by the fan, thereby further reducing the problem of hot air backflow when the fan fails.
[0061] Optional, such as Figure 1 As shown, a limiting baffle 5 is provided on the lower side 12 of the frame 1 to support the baffle 3D at the lowest level.
[0062] By providing the limiting baffle 5, it is possible to prevent the baffle 3D at the lowest level from being sucked up by other fans during rotation, and further avoid the problem of hot air backflow when the fan is not running or fails.
[0063] Correspondingly, the present application also provides a fan 200, such as Figure 3 As shown, including:
[0064] Sector 6; and
[0065] The fan shutter 100 as described in any of the above items;
[0066] The fan shutter 100 is arranged on one side of the air outlet of the fan body 6 .
[0067] The fan 200 can be set in an electronic device, which can be a personal computer, a switching device, a routing device, a server, etc. There can be one fan 200 in the electronic device, or a fan group consisting of multiple fans 200 can be set. It can be set according to actual needs and there is no limitation on this.
[0068] In the embodiments of the present specification, a flexible limiting wire is provided for the baffle in the fan shutter. When the fan is not running or is in a faulty state, the baffle blocks the air outlet and the limiting wire is bent and stored. When the fan is in operation, the baffle is tilted and the limiting wire is straightened, so that the baffle of the previous level and the baffle of the current level form an integrated force, thereby avoiding the problem of the baffle being stuck due to excessive tilting when the wind is strong, preventing the phenomenon of hot air backflow when the fan is not running or is in a faulty state, and further improving the heat dissipation reliability of the electronic equipment.
