Description

Background
With the coming of the electronic age, the application field of electronic equipment is more and more extensive, and the requirements on the service life and the service efficiency of each part of the electronic equipment are more and more strict.
In the application process of the electronic equipment, the operation of the components usually generates heat, if the heat cannot be dissipated timely, the components are heated, the influence of high temperature on the materials of the electronic components is very obvious, and finally the operation of the electronic equipment is damaged. Particularly, in recent years, integrated electronic devices have been developed, and the number of components is large, and the amount of generated heat is not negligible. For example, a server capable of providing external services through a network mainly includes a Central Processing Unit (CPU), a memory, a chipset, an I/O bus, I/O devices, a power supply, a chassis, and the like, the frequency of the CPU used by the server is usually high, some servers also include dual CPUs or multiple CPUs, and a plurality of high-speed Small Computer System Interface (SCSI) hard disks and high-power supplies, and heat generated by these components quickly heats the interior of the chassis, and whether hot air can be exhausted as soon as possible is an important condition for the stable operation of the server. If the temperature is too high, the running speed is too slow, and problems of restarting, dead halt and the like can be caused. To solve this problem, a fan is generally provided in the electronic apparatus to dissipate heat. For example, in a rack server, a plurality of parallel rows of operating fans are usually installed at the rear of the rack to form a fan wall, so as to safely and timely dissipate heat of equipment in the rack server, maintain the operating speed of the server and the stability of the system, and prolong the service life of components.
The problem of overhigh temperature in the operation process of the electronic equipment is solved to a certain extent by the arrangement of the working fan. However, once the fan fails, if the fan cannot be repaired by workers in time, the electronic equipment still has the problem of high-temperature operation. For example, for important enterprises such as securities, banks, post and telecommunications, a cabinet server is often adopted, the internal structure is complex, the number of devices is large, once a fan has a problem, the server is in a dead halt state due to overhigh temperature, a large amount of data can be lost, the loss is difficult to estimate, and functions provided by the server, such as proxy internet access, security verification, e-mail service and the like, are all invalid, so that the network is paralyzed, and the consequences are very serious.

Detailed Description
The core of the embodiment of the invention is to provide a fan system for electronic equipment, which comprises a working fan group consisting of one or more working fans, a movable redundant fan and a position adjusting device, wherein the movable redundant fan is configured to provide redundancy for the working fan group when a first fan of the working fan group is abnormal; the position adjusting device is configured to move the redundant fan to a determined position when the first fan of the working fan set is abnormal, so that the redundant fan provides redundancy for the working fan set. The fan system can effectively provide the redundant fan for replacement when the working fan fails, maintain the working stability of the fan and timely dissipate heat for the electronic equipment.
In order that those skilled in the art will better understand the disclosure, the invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1 and 2, fig. 1 is a schematic structural diagram of a fan system according to a first embodiment of the present invention; fig. 2 is a block diagram of a control system in a first embodiment of a fan system according to the present invention.
As shown in fig. 1, the working fans first form a working fan row 1, and a plurality of working fan rows 1 are arranged in parallel to form a frame-shaped working fan group. The position adjusting device specifically comprises parallel guide rails 2 arranged at two sides of the working fan group, a plurality of redundant fans 301 form a redundant fan row 3, and the redundant fan row 3 is slidably arranged on the guide rails 2 so as to be displaced to a determined position along the guide rails 2. In this embodiment, the determined position is behind the operating fan (first fan) that is abnormally operated.
In practice, the position adjustment device may further comprise a driving device for driving the redundant fan 301 to slide along the guide rail 2. Of course, the position of the redundant fan row 3 can also be adjusted manually, and since there is a certain inconvenience in manually adjusting the position of the redundant fan row 3, which is usually provided inside the housing of the electronic device, the drive means are preferably used.
The redundant fans 301 in the redundant fan row 3 can be selected to have the same type and the same number as the working fans 101 in the working fan row 1, and the positions of the redundant fans 301 and the working fans 101 are also corresponding to each other, so that when the redundant fan row 3 slides to the right back of any working fan row 1 on a guide rail, each working fan 101 has the redundant fan 301 corresponding to the redundant fan. It should be understood that one or more rows of redundant fan rows 3 may run on the track 2. The guide rails 2 may be perpendicular to the operating fan row 1 and disposed in parallel at both sides of the operating fan row 1, corresponding to the overall structure of the operating fan assembly. The rear of the working fan row 1 is relative to the working object of the working fan row 1, the working fan row 1 is closer to the plane of the working object, the working fan row 1 and the plane of the redundant fan row 3 need to keep a proper distance, so that the redundant fan row 3 can slide freely at the rear and does not occupy too much space.
Thus, when the working fan fails, the redundant fan 301 can be moved to the position right behind the corresponding abnormally-operating working fan (the first fan), so as to replace the failed working fan to continue to operate, maintain the stability of the fan system, and timely dissipate heat for the electronic equipment. Because the redundant fan 301 is movable, it is usually unnecessary to equip redundant fans with the same number as the working fans, which can save cost, improve the utilization efficiency of the redundant fans, simplify the structure of the electronic equipment and reduce weight, and the actual operation is very simple.
The fan system may further include a detection device 4, a control device 5, and a signal output device 6 (shown in fig. 2), the detection device 4 being configured to monitor an operation state of the operating fan set and output a monitoring signal; the control device 5 is configured to receive the monitoring signal, confirm the abnormal first fan in the working fan group according to the monitoring signal and output a determined position signal; the position adjusting device 8 then moves the redundant fan to the determined position according to the determined position signal. The determined position signal mentioned herein is used to indicate that the working fan set can maintain the original working state of the first fan before the abnormality occurs after the redundant fan moves to the determined position. For example, the determined position is a corresponding position of the first fan in the working fan group; or, the determined position is a predetermined position in the working fan set.
In the working process, the detection device 4 generally monitors the rotating speed or other working state parameters of each working fan 101 in the working fan set, and feeds back the monitored data and position signals of each working fan to the control device 5, when the monitored parameters do not conform to the value range set by the control device 5, the operation of the working fan set is abnormal, at the moment, the control device 5 outputs a signal to the control signal output device 6, the operation of the working fan set is reflected to a worker to generate a fault, and meanwhile, the operation of the original fault fan is stopped. Of course, the control device 5 may also shut down the failed fan after the redundant fan moves to the determined position, so as to provide the function of dissipating heat for the electronic device to the maximum extent.
The whole device can sensitively sense whether the working fan set fails or not and send out a signal to remind a worker, so that the worker can quickly know the existence of the failure, and the redundant fan 301 replaces the failed fan to continue working before the failure of the working fan 101 causes further loss.
When the working fan set runs abnormally, the signal output device 6 can send a signal to the remote monitoring interface, so that a worker can remotely monitor the running condition of the fan system. Of course, optical or acoustic signals, or both, may be emitted. The sound signal may be a warning sound when a fault occurs in a common electronic device, for example, a warning sound is given when some hardware (memory, hard disk, etc.) in a computer operates abnormally. The light signal may be a normal warning red light, but is not limited thereto as long as the purpose of prompting the staff is achieved.
When the operating fan assembly is abnormally operated, the control device 5 may activate the driving device of the position adjusting device. The control device 5 determines the specific position of the operating abnormal working fan according to the position signal of the operating abnormal working fan in the monitoring signal sent by the detection device 4, and then the starting driving device of the position adjusting device drives the redundant fan row 3 to move to the operating abnormal working fan along the guide rail 2 to replace the working fan to work. Of course, after the redundant fan bank 3 reaches the rear of the failed fan, the redundant fan bank 3 and the equipment are automatically connected to be immediately started to replace the failed working fan.
The whole replacement process belongs to an automatic mode, and the automatic repair function of the fan system is realized. Therefore, no matter whether the staff is in the field, the equipment is basically not influenced by the fault of the working fan set.
A signal acquisition device 7, which may be a sensor, may be further disposed at a position corresponding to the working fan set and connected to the control device 5. When the redundant fan 301 reaches the position right behind the working fan set, the signal acquisition device 7 outputs a signal to the control device 5, so that the control device 5 outputs a control signal to turn off the position adjusting device. Specifically, the control device 5 may output a control signal to turn off the driving device in the position adjustment device. The signal acquisition device can ensure that the redundant fan runs to a specified determined position, and effective replacement of the failed fan (the first fan) is realized. In practice, the signal acquisition device may be configured to output a determination signal when the redundant fan reaches the determined position by the position adjustment device.
Of course, the control device 5 may also control the failed fan (the first fan) to be turned off after the redundant fan moves to the determined position, so as to provide the function of dissipating heat for the electronic device to the maximum extent.
It should be noted that the position adjusting device is not limited to the implementation manner disclosed in the foregoing first embodiment, and actually, based on the improved design of the transmission design principle, the position adjusting device may have different structural forms to achieve the objective of driving the redundant fan to displace to the determined position. As will be described in detail with respect to the position adjusting means in the following embodiments.

When the cross bar 22 moves transversely along the slide rail 21, the redundant fan 301 can be driven to run transversely, and when the longitudinal bar 23 moves longitudinally along the slide rail 21, the redundant fan 301 can be driven to run longitudinally, so that the redundant fan 301 can run to any position behind the working fan set under the condition of moving longitudinally and transversely to replace any fault working fan (first fan).
In this embodiment, the cross bar 22 and the longitudinal bar 23 can be driven by the first motor 221 and the second motor 231 respectively to displace along the slide rail 21, so as to perform automatic sliding of the redundant fan 301.
Referring to fig. 5, fig. 5 is a schematic structural diagram of a fan system according to a third embodiment of the present invention.
A support rod 31 is arranged behind the working fan group, and the support rod 31 can be vertically arranged on the left side and the right side of the working fan group or transversely arranged on the upper side and the lower side of the working fan group; a transverse shaft 32 which is vertical to the support rod 31 is arranged on the support rod 31; a first chain wheel 33 which rotates coaxially with the transverse shaft 32 is arranged on the transverse shaft; the support rod 31 is provided with a second chain wheel 34; the chain 36 passes around the first sprocket 33 and the second sprocket 34, and the redundant air duct 3 is fixedly arranged on the chain 36.

In order to achieve replacement of each working fan 101 by a redundant fan 301, the number of redundant fans 301 may be equal to the number of working fans per row. Of course, the first chain wheel 33 and the second chain wheel 34 can be displaced laterally, at this time, it is sufficient to fix one redundant fan 301 on the chain 36, and the redundant fan 301 can not only be lifted or moved left and right, and can reach any position behind the working fan set to replace any fault redundant fan (first fan).
Further, in order to ensure the stability of the operation of the redundant fan row 3, a transmission chain 311 may be further provided, a fifth chain wheel 310 which rotates coaxially with the cross bar 32 and a sixth chain wheel 39 which is arranged on the support bar 31 are correspondingly provided, the transmission chain 311 bypasses the fifth chain wheel 310 and the sixth chain wheel 39, as shown in fig. 5, one end of the redundant fan row 3 which is composed of a plurality of redundant fans 301 is fixed with the chain 36, the other end is fixed with the transmission chain 311, and the redundant fan row 3 is lifted and lowered under the synchronous action of the chain 36 and the transmission chain 311.
Specifically, a third sprocket 35, a power transmission chain 37 and a driving device may be provided to realize the rotation of the cross shaft 32, the third sprocket 35 rotates coaxially with the cross shaft 32, an output shaft of the driving device is connected to a fourth sprocket 38, and the power transmission chain 37 bypasses the third sprocket 35 and the fourth sprocket 38. The fourth chain wheel 38 rotates under the action of the driving device to drive the third chain wheel 35 to rotate, and the third chain wheel 35 drives the cross shaft 32 to rotate, thereby achieving the purpose of the invention. Of course, the transverse shaft 32 may be directly connected to the output shaft of the drive device.
Referring to fig. 6, fig. 6 is a schematic structural diagram of a fan system according to a fourth embodiment of the present invention.
A plurality of sliding chutes which are formed by a transverse partition plate 41 and a vertical partition plate 42 and are transversely arranged are arranged behind the working fan group, the sliding chutes are sequentially communicated to form a circuitous channel, and the spacing distance of the channel needs to meet the operation of the redundant fan 301; the transverse partitions 41 are substantially aligned with the spacing between the working fan rows 1, i.e. the channels correspond to the position of the working fan rows 1, ensuring that the redundant fan 301 can be run to a determined position corresponding to the working fan 101. In order to realize that the redundant fan 301 runs along the channel, a chain track can be arranged on one side of the chute channel, specifically, the chain track can be arranged on one side of the transverse partition plate 41 and one side of the vertical partition plate 42, and the redundant fan 301 has a chain wheel matched with the chain track, so that the redundant fan 301 can move to any position behind the working fan group along the channel, and further replace the working fan 101 with abnormal working.

That is, one motor is realized as a power element of two motions completely through the structural design, and the description is omitted here.
Referring to fig. 7, fig. 7 is a schematic structural diagram of a fan system according to a fifth embodiment of the present invention.
The principle of the present invention is the same as that of the fourth embodiment, and the difference between the two embodiments is that a plurality of chutes formed by the horizontal baffles 51 and the vertical baffles 52 are arranged in the longitudinal direction behind the working fan set in the present embodiment, and are sequentially communicated to form a circuitous channel, and the redundant fan 301 can also be moved to any position along the channel to replace the failed working fan (the first fan). Other structures are completely the same as those of the fourth embodiment, and the description of this embodiment is omitted.
The position adjusting devices of the fan systems disclosed in the five embodiments are located substantially behind the working fan. In the working process, when a first fan in a working fan set breaks down or is abnormal, the detection device monitors the running state of the working fan set and outputs a monitoring signal; the control device confirms the abnormal first fan in the working fan group according to the monitoring signal and outputs a determined position signal as a corresponding position signal of the first fan in the working fan group; the determined position signal is used for indicating that the working fan group can keep the original working state of the first fan before the first fan is abnormal after the redundant fan moves to the determined position; the position adjusting device moves the redundant fan to the position of the first fan or behind the first fan according to the determined position signal to replace the first fan.
In another case, the control device determines the first fan with abnormality in the working fan group according to the monitoring signal, and outputs a determined position signal as a predetermined position signal in the working fan group, wherein the position adjusting device moves the redundant fan to a predetermined position in the working fan group according to the predetermined position signal, so that the working fan group can maintain the original working state of the first fan before abnormality occurs. Specifically, the next adjacent normal operation fan of the failed/abnormal first fan is moved to the position of the first fan to replace the first fan, and so on, the redundant fan is moved to the predetermined position of the previous normal operation fan adjacent to the redundant fan to replace the previous normal operation fan adjacent to the redundant fan. Therefore, the working stability of the fan is maintained, and the electronic equipment is timely cooled. Moreover, the movable connection of the redundant fan can improve the utilization efficiency of the redundant fan, and the operation is simple and convenient.
Referring to fig. 8, fig. 8 is a schematic structural diagram of a fan system according to a sixth embodiment of the present invention.
The periphery of the working fan group is provided with a storage structure 61 for storing fans, namely, a plurality of redundant fans 301 are stored outside the working fan 101, and the redundant fans and the 301 are approximately positioned on the same plane with the working fan group; in this embodiment, the working fan 101 and the redundant fan 301 are both movable, and the specific implementation manner includes various manners, such as motor driving, sprocket driving, and the like; each working fan bank 1 is provided with an inlet for a redundant fan 301 on a respective one side and an outlet for a failed working fan 101 on the other side. Thus, when an abnormal operation of the working fans 101 occurs, the redundant fans 301 enter from the inlet and push the working fan row 1 where the failed working fan 101 is located until the failed working fan 101 is pushed to move from the outlet into the storage structure 61, and the number of the redundant fans 301 entering from the inlet is equal to the number of the failed working fans 101 moving from the outlet.
