In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.
The main implementation principle, the specific implementation mode and the corresponding beneficial effects of the technical scheme of the embodiment of the present application are explained in detail with reference to the accompanying drawings.
An embodiment of the present application provides a flow rate adjustment device, as shown in a in fig. 3, including:
a frame 1;
at least one node 10 arranged on a first side of the accommodating space formed by the frame 1;
at least one fan 11 disposed at a second side opposite to the first side in the accommodating space;
at least one partition 12 disposed between at least one node 10 and at least one fan 11;
wherein the cooling zone of the at least one fan 11 comprises at least two sub-cooling zones, a first partition of the at least one partition 12 being rotatable between the at least one node 10 and the at least one fan 11 to vary the air flow of two sub-cooling zones of the at least two sub-cooling zones adjacent to the first partition.
In particular, the cooling system of the rack may comprise only one fan, i.e. when the at least one fan 11 is a first fan, the at least one partition 12 is adapted to divide the cooling area of the first fan into at least two sub-cooling areas.
For example: when the flow rate adjusting device includes one partition plate, the cooling area of the first fan may be divided into two sub-cooling areas, such as area one and area two in fig. 4, where the air flow rates of the area one and area two may change with the rotation of the partition plate, where the solid line in fig. 4 is the position before the rotation of the partition plate, and the dotted line is the position after the rotation of the partition plate, the air flow rate of the area one increases and the air flow rate of the area two decreases after the rotation of the partition plate from the solid line position to the dotted line position.
Also, when the flow rate adjusting means includes two partitions, it is possible to divide the cooling area of the first fan into three sub-cooling areas and to change the flow rates of air in the three sub-cooling areas by the rotation of the partitions.
In this embodiment, the cooling system of the rack may also include a plurality of fans, that is, at least one fan 11 is a plurality of fans, and assuming that at least one partition 12 is a first partition, the first partition may divide the cooling area of N fans in the plurality of fans into a first sub-cooling area, and then divide the cooling area of other fans except the N fans in the plurality of fans into a second sub-cooling area.
For example: as shown in fig. 5, the flow rate adjusting device includes a partition, and the cooling system includes three fans, namely, a fan 1, a fan 2, and a fan 3, so that when the partition is in the position of the solid line in the figure, the cooling areas of the fan 1 and the fan 2 are divided into a first sub-cooling area, and the cooling area of the fan 3 is divided into a second sub-cooling area; and when the partition is in the position of the dotted line in the figure, the cooling area of the fan 1 is divided into a first sub-cooling area, and the cooling areas of the fan 2 and the fan 3 are divided into a second sub-cooling area.
In the present embodiment, to enable the partition to rotate about the node, each of the at least one partition 12 has a first end that is rotatably connected to one of the at least one node 10.
Specifically, when the partition plate rotates, the sizes of the air outlet apertures of the two sub-cooling areas adjacent to the partition plate can be changed, as shown in b in fig. 3, when the partition plate rotates upwards, the air outlet aperture of the area 1 decreases, the node resistance to the air flow field increases, the air flow decreases, the air outlet aperture of the area 2 increases, the node resistance to the air flow field decreases, and the air flow increases. When the partition plate rotates downwards, the air outlet aperture of the area 1 is increased, the node resistance to the air flow field is reduced, the air flow is increased, the air outlet aperture of the area 2 is reduced, the node resistance to the air flow field is increased, and the air flow is reduced.
In particular embodiments, each of the at least one nodes 10 may be rotatably coupled to one of the at least one partition 12 for regulating the flow of air available to each node within the rack.
Specifically, each node in the rack is in a separate sub-cooling zone when each node is connected to a partition, as shown in a in fig. 3.
In this embodiment, the flow rate adjusting device further includes at least one rotation driving member, the first end of each partition board is connected with one rotation driving member of the at least one rotation driving member, and the rotation driving member is configured to drive each partition board to rotate between at least one node 10 and at least one fan 11 by using the first end as an axis.
Specifically, the rotary drive member is provided on the node side, and the rotary drive member may be a motor rotary structure, and each partition is connected to one motor rotary structure so that each partition can be independently rotated to change the cooling area of the fan.
In the embodiment of the present application, in order to reasonably distribute the air flow between the high load node and the low load node, the rotation of the partition plate needs to be controlled.
In the first mode, the air flow required by the node is calculated through the temperature of the node, and then the partition plate is controlled to rotate according to the relation between the air flow of the node and the angle of the partition plate.
Specifically, a temperature detection unit is provided for each of an exhaust port and an intake port of each of the at least one node 10, wherein the exhaust port is located on a side of the each node close to 1 of the at least one fan 11, and the intake port is located on a side of the each node far from the at least one fan 11, as shown by a in fig. 3.
In the rack, the fan is a system blowing out, and for the system, the air flow field is a suction flow field, as shown in a in fig. 3, so that the air flow field is driven to flow from the left to the right, and therefore, the exhaust port is right of the node point, and the left is the intake port.
In a specific implementation, the temperature detection unit may be a temperature sensor, the temperature sensor transmits detected data to the control unit, and the control unit calculates the node air flow rate of each node according to the exhaust port temperature and the intake port temperature of each node.
In particular implementations, the node air flow required for each node may be calculated by the following equation.
Q＝1.76P/(△T)
Where Q is the node air flow in the present embodiment, P is the node, and Δ T is the difference between the outlet temperature and the inlet temperature of the node.
Then, according to the corresponding relation between the standard air flow of a first node in at least one node 10 and the angle of the partition plate, controlling the first partition plate between the first node and a second node in at least one node 10 to rotate so as to increase the air flow of a cooling area where the first node is located, reduce the air flow of the cooling area where the second node is located, or reduce the air flow of the cooling area where the first node is located, and increase the air flow of the cooling area where the second node is located;
the partition angle is an included angle between the first partition and the first node, and the second node is a node adjacent to the first node.
For example: when the nodes are installed on the rack, the partition plates of the flow regulating device are horizontal, when the load of one node is increased, the temperature of the node parts is increased, and further the temperature of the exhaust port is increased, therefore, the air flow required by the node is also increased, the angle of the partition plates is adjusted in a mode shown as a in fig. 6, the air outlet aperture of the node is increased by adjusting the angle of the partition plates, the resistance of the node to an air flow field is reduced, and further the air flow obtained by the node is increased, so that the heat of the node is dissipated.
Another example is: when the nodes are installed on the rack, the partition plates of the flow regulating device are horizontal, when one of the nodes is IDLE load (the node system does not use any software or execution program), and the load of the node adjacent to the node is increased, the angle of the partition plates is adjusted in a manner shown as b in fig. 6, the air outlet aperture of the node is reduced, the resistance of the node to an air flow field is increased, the air flow obtained by the node is further reduced, and the air flow obtained by the adjacent node is increased, so that the adjacent node is cooled.
In the specific implementation process, the partition plate angle can be finely adjusted, the air flow obtained by the node is continuously changed in the process of finely adjusting the partition plate angle, and due to the heat dissipation of the node, the temperature of an air outlet and the temperature of an air inlet of the node are also changed, so that the air flow of the node required currently by the node needs to be recalculated in the process of finely adjusting the partition plate angle.
Finally, when the current node air flow required to be obtained at the current node of the node corresponds to the angle of the current partition plate, namely when the angle of the partition plate is the current angle and the air flow which can be actually obtained by the partition plate is the current air flow, stopping rotating the partition plate; or stopping the rotation of the diaphragm when the temperature of the target node decreases to the target temperature.
In the embodiment of the present application, the more software or programs that are used or executed by the node system, the greater the load on the node, the higher the temperature of the node components, and the higher the exhaust port temperature.
In the present embodiment, baffle rotation may also be controlled by the node air flow rate of adjacent nodes.
Specifically, when the node air flow rate of the first node is larger than the node air flow rate required by the second node and the air flow rate available to the first node needs to be increased, the first partition plate is moved in the direction of the second node to increase the outlet air diameter of the first node, increase the air flow rate available to the first node, and decrease the air flow rate available to the second node.
When the node air flow at the first node is smaller than the node air flow required by the second node, the air flow which can be obtained by the first node needs to be reduced, and the first partition plate is moved towards the first node so as to reduce the air outlet aperture of the first node, reduce the air flow obtained by the first node and increase the air flow obtained by the first node.
In the second mode, the rotation of the partition plate is controlled by the size of the node load.
Specifically, a load detection unit is provided on each node for detecting a load of said each node.
In a specific implementation process, the load of a node may be represented by the CPU usage rate or the memory occupancy rate (memory) caused by the software or the executed program that each node is running.
Specifically, the higher the CPU utilization or memory occupancy, the greater the load on the node; the lower the CPU utilization or memory occupancy, the smaller the load of the node.
In the present embodiment, the control unit is connected to the rotary drive and, in the event of a change in the load at a first node of the at least one node 10, controls the rotation of a first partition connected to said first node to increase or decrease the air flow in the cooling zone in which the first node is located.
Specifically, when the load of the first node is increased, the first diaphragm connected to the first node is controlled to rotate, as shown by a in fig. 6, to increase the air outlet opening size and thus increase the air flow rate obtained by the first node, and when the load of the first node is decreased, the first diaphragm is controlled to rotate, as shown by b in fig. 6, to decrease the air outlet opening size and thus decrease the air flow rate obtained by the first node.
In the embodiment of the present application, assuming that the first node is rotatably connected to the first partition, when the rack is in a full structure, as shown in a in fig. 3, the first partition of the flow rate adjusting device is horizontal, and when the first partition is controlled to rotate, it is necessary to determine whether to rotate the partition, and the direction in which the partition rotates, in combination with the load change of the first node and the node adjacent to the first node.
For example: when the load at the first node becomes large and the load at the second node adjacent to the first node becomes small, or an IDLE load, the rotation of the first partition plate may be controlled to increase the air flow rate obtained at the first node and decrease the air flow rate obtained at the second node.
When the loads of the first node and the second node are increased, the rotating partition plate cannot effectively dissipate heat of the first node and the second node, and at the moment, the rotating speed of a system fan can be increased to dissipate heat of the first node and the second node.
In the embodiment of the present application, when the rack is in the less-than-full configuration, as shown in fig. 7A-7B, the first partition of the flow rate adjustment device is horizontal, and the node adjacent to the first node is an empty node, and when the load of the first node changes, the first partition is controlled to rotate to increase the air flow rate obtained by the first node.

In the prior art, in order to resist the flow of the air flow through the empty node, a dummy node 13 is installed at the empty node, as shown in fig. 2, although the dummy node 13 can block the air flow from flowing through the empty node, a flow field backflow condition is generated in the empty node, and for the system, there is no heat dissipation effect.
In the embodiment of the present application, the baffle 14 may be disposed between two adjacent nodes, as shown in fig. 7A.
The baffle 14 may also be disposed between the nodes and the fan, as shown in fig. 7B, the baffle 14 has a second end rotatably connected to one of the at least one node 10 and a third end opposite the second end, the third end abutting one of the at least one fan 11, i.e., the flow regulating device at the node where it is not installed is not horizontal, but rather is an angled baffle 14.
In this application embodiment, baffle 14 can rotate around the node, and when the baffle rotated downwards, baffle 14 rotated downwards to change the size of air-out bore, when the baffle upwards rotated, baffle 14 upwards rotated.
In the embodiment of the present application, the partition and the baffle 14 may be made of elastic materials, that is, the length of the partition and the baffle 14 may be changed within a certain range. Or the length of the partition board can be fixed, and when the partition board is not in the horizontal position, a gap exists between the partition board and the fan.
