Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
Fig. 1 is a schematic structural diagram of a heat dissipation device according to an embodiment of the present invention. Referring to fig. 1, the heat dissipating device includes: a control module 101, a main fan set 102, at least one backup fan 103, and a conveyor 104.
The main fan set 102 includes a plurality of fans disposed side by side, and the plurality of fans rotate normally to drive the air flow in the front area of the fans, so that the heat in the front area is taken away through the air flow to dissipate the heat in the front area. However, during the operation, one or more fans may fail, and at this time, the failed fan cannot dissipate heat from the front area, which affects the overall heat dissipation effect of the heat dissipation device.
Therefore, in the embodiment of the present invention, at least one spare fan 103 is disposed in the heat dissipation apparatus, and the spare fan 103 is used to replace the failed fan to work when one or more fans in the main fan set 102 fail, so as to continuously dissipate heat in the area in front of the failed fan.
The number of at least one spare fan 103 is smaller than the number of fans in the main fan group 102, since the hardware cost is too high due to the higher number of spare fans 103, considering that the possibility of simultaneous failure of all fans in the main fan group 102 is less. For example, the number of fans in the main fan set is 3, and the number of standby fans is 1 or 2.
In addition, the heat sink further includes a control module 101 and a transmission device 104, the control module 101 is connected to each fan of the main fan set 102, each backup fan 103, and the transmission device 104, the transmission device is used to fix any backup fan 103 of at least one backup fan 103 on the transmission device 104 and transmit the backup fan 103, and the control module 101 is used to control the heat sink, and may be a processor, a BMC (Baseboard Management Controller), or other components for controlling.
In the working process, the control module 101 detects the position of the failed fan in the main fan set 102, controls the conveying device 104, moves the standby fan 103 to the standby position corresponding to the position of the failed fan, enables the standby fan 103 to work at the standby position, and radiates heat to the front area through rotation.
When the heat dissipation device is started, all the fans in the main fan set 102 and the standby fan 103 are started, each fan in the main fan set 102 and the standby fan 103 start to work, and when the fan in the subsequent main fan set 102 fails, the standby fan 103 is moved to a required standby position to replace the failed fan to work, so that the heat dissipation effect is achieved. Or, when the heat dissipation device is started, only each fan in the main fan set 102 is started, the standby fan 103 is not started, and the standby fan 103 is started again when the standby fan 103 is moved to a required standby position to replace a failed fan to work, so that the heat dissipation effect is achieved.
Even if a small number of spare fans 103 are arranged, the positions of the spare fans 103 can be flexibly adjusted through the conveying device 104 according to the positions of the failed fans, so that the spare fans 103 can work instead of the failed fans, the heat dissipation effect can be ensured, the number of the spare fans can be reduced, and the hardware cost is reduced.
Alternatively, the control module 101 may set a preset rotation speed range, where the preset rotation speed range refers to a range to which the rotation speed of the fan during normal operation belongs. In the working process of the heat dissipation device, the control module 101 obtains the rotation speed of each fan in the main fan set 102, and determines whether the obtained rotation speed belongs to a preset rotation speed range, and when the rotation speed of any fan does not belong to the preset rotation speed range, determines the fan not belonging to the preset rotation speed range as a failed fan, and determines the position of the failed fan. For example, the preset rotation speed range is more than 4000 rpm, and when one of the fans is 1000 rpm, the rotation speed of the fan is low, the fan can be considered to be failed, and can not work normally, so that the fan is identified as a failed fan.
During the operation of each fan in the main fan set 102, the rotation speed of the local end can be detected by a sensor and other elements, and sent to the control module 101, so that the control module 101 obtains the rotation speed of each fan.
The position of each fan in the main fan set 102 is fixed and has an adjacently disposed standby position at which the standby fan 103 can be placed. Correspondingly, the conveying device 104 is also arranged adjacent to the main fan set 102, and the conveying device 104 and the at least one spare fan 103 are positioned on the same side of the main fan set 102, so that the conveying device 104 can convey any spare fan 103 and move the spare fan 103 to a spare position corresponding to the position of the failed fan.
For example, the standby position of each fan may be located in front of or behind the fan, and correspondingly, the conveyor 104 is also located in front of or behind the main fan set 102, and the conveyor 104 is located on the same side of the main fan set 102 as the at least one standby fan 103.
Moreover, the conveyor 104 is substantially parallel to the fan arrangement direction of the main fan set 102, so that when any one of the spare fans 103 is conveyed by the conveyor 104, the moving direction of the spare fan 103 can be ensured to be substantially parallel to the fan arrangement direction of the main fan set 102, and the spare fan can be moved on the conveyor 104 arranged adjacent to the main fan set 102 and finally placed at a spare position corresponding to the position of the failed fan. It can be understood that the arrangement direction of the conveying device 104 and the main fan set 102 may be substantially parallel, for example, the included angle between the arrangement direction of the conveying device 104 and the main fan set 102 is greater than 0 degree and less than 30 degrees, such as 5 degrees and 10 degrees, as long as it can be ensured that the spare fan can replace the failed fan to work, so that the heat dissipation effect of the spare fan can be ensured, the position of the conveying device 104 is not limited too much, and the manner of arranging the conveying device is flexible.
Alternatively, considering that any fan in the main fan group 102 may fail, when the length of the conveying device 104 is less than the total length of the main fan group 102, it may happen that the conveying device 104 cannot convey the spare fan 103 to the spare position corresponding to the position of the failed fan when a fan far away from the spare fan 103 fails, and only when the length of the conveying device 104 is not less than the total length of the main fan group 102, it can be ensured that the spare fan 103 can be conveyed to the spare position corresponding to the position of the failed fan when any fan fails. Therefore, in the embodiment of the present invention, the length of the conveying device 104 is not less than the total length of the fans of the main fan set 102.
It should be noted that, the heat dissipation device in the embodiment of the present invention may use different numbers of spare fans and different numbers of conveying devices, and the spare fans are moved by different conveying manners.
In a possible implementation manner, fig. 2 is a schematic structural diagram of a heat dissipation apparatus provided in an embodiment of the present invention, and referring to fig. 2, the heat dissipation apparatus includes only one spare fan 103 and one conveying device 104, that is, in an "N + 1" manner, where N represents the number of fans in the main fan set, that is, a spare fan is additionally provided in addition to the main fan set 102. The standby fan 103 is fixed on the conveying device 104, and the standby position corresponding to the position of each fan in the main fan set 102 is on the conveying device 104.
When the control module 101 detects that any fan in the main fan set 102 fails, the position of the failed fan is determined, a standby position corresponding to the position of the failed fan on the conveying device 104 is determined, and the conveying device 104 is controlled to convey the standby fan 103 to the determined standby position until the standby fan 103 moves to the standby position, and the conveying is stopped. In this case, the backup fan 103 is located in front of or behind the failed fan, and can operate in place of the failed fan.
In another possible implementation manner, fig. 3 is a schematic structural diagram of a heat dissipation apparatus provided in an embodiment of the present invention, and referring to fig. 3, the heat dissipation apparatus includes a plurality of standby fans 103 and a conveying device 104, that is, an "N + N" manner is adopted, where N denotes the number of fans in a main fan group, N denotes the number of standby fans, and N is a positive integer greater than 1, that is, a plurality of standby fans are additionally disposed besides the main fan group 102. The conveyor 104 may need to transport multiple spare fans 103 back and forth.
In one embodiment, to facilitate transport by the transport apparatus 104, the plurality of backup fans 103 are not initially placed on the transport apparatus, but are placed on a side of the transport apparatus 104, and the backup location corresponding to the location of each fan in the main fan set 102 is not on the transport apparatus 104, but is between the main fan set 102 and the transport apparatus 104. Alternatively, in another embodiment, the plurality of backup fans 103 are disposed at one or both ends of the conveyor 104, such as by a rack-and-pinion connection at one or both ends of the conveyor 104.
Taking the first spare fan 103 and the second spare fan 103 as an example, when the control module 101 detects that any fan in the main fan set 102 fails, the position of the failed fan is determined, the transmission device 104 is controlled to be fixed with the first spare fan 103, and the first spare fan 103 is controlled to transmit to a first spare position corresponding to the position of the failed fan, until the first spare fan 103 moves to the first spare position, the first spare fan 103 is placed at the first spare position.
Then, when the control module 101 detects that another fan in the main fan set 102 fails, the position of the another failed fan is determined, the transmission device 104 and the second backup fan 103 are controlled to be fixed, and the second backup fan 103 is controlled to transmit to a second backup position corresponding to the position of the another failed fan, until the second backup fan 103 moves to the second backup position, the second backup fan 103 is placed at the second backup position. The conveyor 104 may then continue to convey additional backup fans 103.
In yet another possible implementation manner, fig. 4 is a schematic structural diagram of a heat dissipation apparatus provided in an embodiment of the present invention, and referring to fig. 4, the heat dissipation apparatus includes a plurality of standby fans 103 and a conveying device 104 with the same number as the standby fans 103, that is, in an "N + N" manner, a plurality of standby fans are additionally disposed in addition to the main fan group 102. A spare fan 103 is fixed on each conveyor 104, and a spare position corresponding to the position of each fan in the main fan set 102 is positioned on the conveyor 104, so that a plurality of conveyors 104 are arranged in front of or behind the main fan set.
Taking the first spare fan 103 and the second spare fan 103 as an example, when the control module 101 detects that any fan in the main fan set 102 fails, the position of the failed fan is determined, the first spare fan 103 fixed on the first conveying device 104 is controlled to convey to the first spare position corresponding to the position of the failed fan, and the first conveying device 104 is controlled to stop moving until the first spare fan 103 moves to the first spare position.
Then, when the control module 101 detects that another fan in the main fan set 102 fails, the position of the another failed fan is determined, and the second spare fan 103 fixed on the second conveying device 104 is controlled to convey to a second spare position corresponding to the position of the failed fan, until the second spare fan 103 moves to the second spare position, the second conveying device 104 is controlled to stop moving.
In the above three possible implementations, the control module 101 may detect that two or more fans in the main fan group 102 fail, and when the number of the standby fans 103 is less than the number of the failed fans, the control module 101 determines a standby position corresponding to the position of each failed fan, determines the position of each standby fan 103, determines a standby position closest to the position of each standby fan 103 according to each standby position and the position of each standby fan 103, and moves each standby fan to the standby position closest to the position where it is located.
For example, a standby position closest to the position of a first standby fan is determined from among standby positions corresponding to two or more failed fans according to the position of the first standby fan, and the first standby fan is moved to the standby position determined this time. And then, according to the position of the second spare fan, continuously determining the spare position closest to the position from the spare positions corresponding to the rest failed fans, moving the second spare fan to the spare position determined this time, and so on until all the spare fans are moved to the determined spare positions, and replacing the corresponding failed fans by all the spare fans in the heat dissipation device to work.
In the latter two possible implementation manners, the heat dissipation device includes two or more than two backup fans 103, when the control module 101 detects that any one fan in the main fan set fails, the control module 101 determines a backup position corresponding to the position of the failed fan and the position of each backup fan 103, determines a backup fan closest to the backup position according to the backup position corresponding to the position of the failed fan and the position of each backup fan 103, and moves the determined backup fan to the backup position, or the control module 101 acquires the rotation speed of each backup fan 103, determines a backup fan 103 with the same rotation speed as the failed fan, and transfers the backup fan 103 to the backup position.
In the heat dissipation device provided by the embodiment of the invention, the control module is respectively connected with each fan of the main fan set, each spare fan and the transmission device, wherein the number of the spare fans is smaller than that of the fans in the main fan set, any spare fan is fixed on the transmission device by the transmission device, the control module detects the position of a failed fan in the main fan set and controls the transmission device to move the spare fan to a spare position corresponding to the position of the failed fan, and the spare fan normally works on the spare position to replace the failed fan for heat dissipation. Through setting up less quantity spare fan, under the prerequisite of guaranteeing the heat dissipation effect, reduced spare fan's cost, reduced the consumption that the fan during operation produced, reduced the noise.
Fig. 5 is a schematic structural diagram of a conveying apparatus according to an embodiment of the present invention. Referring to fig. 5, the conveying device 104 includes a driving portion 501, a transmission portion 502 and a connecting portion 503, the control module 101 is connected to the driving portion 501, the driving portion 501 is movably connected to the transmission portion 502, and the connecting portion 503 is movable on the transmission portion 502. When the driving portion 501 rotates, the driving portion 502 can be driven to rotate, and when the driving portion 502 rotates, the connecting portion 503 can be driven to move on the driving portion 502. And, the length of the connecting portion 503 is smaller than the length of the transmission portion 502 to ensure that the connecting portion 503 can move freely on the transmission portion 502.
The control module 101 controls the connection part 503 to fix the backup fan 103 on the connection part 503, and the control module 101 controls the driving part 501 to rotate, so as to drive the transmission part 502 to rotate and the connection part 503 to move on the transmission part 502, so as to drive the backup fan 103 on the connection part 503 to move, and thus the backup fan 103 is moved to a backup position corresponding to the position of the failed fan.
The connection portion 503 may fix the backup fan 103 to the connection portion 503 when the heat dissipation device is started, and then directly transmit the backup fan 103 when the control module 101 detects the position of the failed fan. Alternatively, when the control module 101 detects a failed fan, the control connection unit 503 may fix the backup fan 103 to the connection unit 503.
In a possible implementation manner, the driving portion 501 is provided with an internal thread in a region connected with the transmission portion 502, the transmission portion 502 is provided with an external thread, the driving portion 501 and the transmission portion 502 can be in threaded connection, the connecting portion 503 is provided with an internal thread, and the connecting portion 503 is connected to the transmission portion 502 through a threaded connection sleeve. When the driving portion 501 controls the connecting portion to rotate, the transmission portion 502 rotates accordingly. The driving portion 501 rotates to drive the transmission portion 502 to rotate, so as to drive the connecting portion 503 to move on the transmission portion 502.
For example, the driving unit 501 may be a motor or other components having a driving function. The transmission part 502 may be a rotating shaft, a conveyor belt, or other components having transmission functions. The connecting portion 503 may be a sleeve or other components that are coupled to the driving portion 502 and move on the driving portion 502.
In another possible implementation manner, referring to fig. 6, it is considered that the rotation direction of the driving portion 501 is consistent with the rotation direction of the transmission portion 502, and the rotation direction of the transmission portion 502 affects the moving direction of the connecting portion 503. Therefore, the control module 101 may determine the rotation direction of the driving portion 501 according to the standby position corresponding to the failed fan position and the current position of the standby fan 103, so that the moving direction of the connecting portion 503 is directed to the standby position from the current position of the standby fan 103. The control module 101 controls the driving portion 501 to rotate according to the rotation direction, so as to drive the transmission portion 502 to rotate according to the rotation direction and the connection portion 503 to move on the transmission portion 502 according to the moving direction, so that the standby fan 103 moves to the standby position corresponding to the failed fan position.
In a possible implementation manner, a first latch is disposed above the connecting portion 503, and a second latch matching the first latch is disposed below the standby fan 103, and the first latch and the second latch can be connected in a snap-fit manner, so that the standby fan 103 is fixed on the connecting portion 503.
When the number of the standby fans 103 is the same as that of the conveying devices 104, each conveying device 104 only needs to convey one standby fan 103, the connecting portion 503 is connected with the second clamping device of the standby fan 103 in a clamping manner through the first clamping device, so that the standby fan 103 is fixed on the conveying device 104, each time the control module 101 controls the driving portion 501 to rotate, the transmission portion 502 is driven to rotate, the connecting portion 503 is driven to move, the standby fan 103 connected with the connecting portion 503 in a clamping manner also moves along with the standby fan, and the operation is finished when the standby fan 103 stops moving to the standby position, or the connecting portion 503 is controlled to separate the first clamping device from the second clamping device of the standby fan 103.
When the heat dissipation device is started, the connection portion 503 may be connected to the second latch device of the standby fan 103 through the first latch device in a snap-fit manner, and then, when the control module 101 detects the position of the failed fan, the standby fan 103 may be directly conveyed. Alternatively, when the control module 101 detects a failed fan, the control connection part 503 may be engaged with the second engaging device of the backup fan 103 through the first engaging device.
