It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are used for distinguishing two entities with the same name but different names or different parameters, and it should be noted that "first" and "second" are merely for convenience of description and should not be construed as limitations of the embodiments of the present invention, and they are not described in any more detail in the following embodiments.
It should be noted that, in the embodiment of the present invention, the cabinet is generally made of cold-rolled steel plates or alloys and used for storing the computer and the related control devices, which can provide protection for the storage devices, shield electromagnetic interference, orderly and orderly arrange the devices, and facilitate the maintenance of the devices later.
According to an aspect of the present invention, an embodiment of the present invention provides a server cabinet 1, as shown in fig. 1, the cabinet 1 may include a cabinet body 10, a first air-guiding groove 12 vertically extending and disposed in the cabinet body 1, a plurality of second air-guiding grooves 13 longitudinally extending and disposed in the cabinet body 1, a controller 14, and a cooling device 15. The cabinet 10 has a plurality of accommodating spaces 11 for accommodating servers therein, the first air guiding groove 12 may include a plurality of air outlets 121 arranged at intervals, two ends of each second air guiding groove 13 are provided with an air inlet 131 and a wind shielding plate 132, a side surface is provided with an opening 133/134 facing the air outlet 121 or the server, the refrigeration device 15 is communicated with the first air guiding groove 12, and the controller 14 is configured to detect an external temperature, and control the wind shielding plate 132 to close the air inlet 131 or the opening 133 facing the air outlet according to the external temperature and correspondingly control the refrigeration device 15.
The air inlet 131 or the opening 133 facing the air outlet 121 is closed by the external temperature detected by the controller 14, so that the cabinet 1 can radiate heat through the second air guide groove 13 during centralized heat radiation, and the cabinet 1 can radiate heat through the first air guide groove 12 and the refrigerating device 15 during centralized heat radiation failure. Therefore, the effect of concentrated heat dissipation can be guaranteed, and the problems of server downtime or restarting caused by concentrated heat dissipation faults and high temperature can be avoided.
In some embodiments, the vertically extending first air guiding groove 12 shown in fig. 1 may be disposed inside the cabinet 10, for example, may be disposed at a position close to a rotation axis of the cabinet 10, and the first air guiding groove 12 may further include an air guiding cover 122 connecting the air outlet 121 and an opening 133 facing the air outlet 121 and disposed on a side of the second air guiding cover 122, such that the cool air generated by the refrigeration device 15 directly flows into the second air guiding cover 122 through the air outlet 121 of the first air guiding groove 12, and thus, the loss of the airflow is reduced.
In some embodiments, the number of the air outlets 121 disposed in the first air guiding groove 12 may be the same as that of the second air guiding groove 13 or the accommodating space 11. In some embodiments, each air outlet 121 may be closed by a partition before being used, and only when the air outlet 121 needs to be used, the partition is removed from the side in a pull-out manner, and the unused air outlet 121 continues to be closed by the partition. For example, when a server is not disposed in the accommodating space 11 of a certain floor, the air outlet 121 corresponding to the accommodating space 11 may not be used, which not only saves energy consumption, but also improves heat dissipation efficiency. In some embodiments, the baffles may also be electronically controlled by the controller 14.
In some embodiments, a plurality of longitudinally extending second air guiding channels 13, shown in fig. 1, are provided on the front door of the cabinet 10. And the opening 134 facing the server and disposed on the side of the wind scooper 122 corresponds to the wind inlet of the server.
In some embodiments, the opening 134 facing the server is disposed corresponding to the air inlet of the server, so that the external cold air enters from two ends of the second air guiding groove 13 under the suction force of the air inlet of the server and directly enters the air inlet of the server through the opening 134 facing the server, thereby preventing the cold air from flowing into other places to affect heat dissipation.
The number of the second air guiding grooves 13 is the same as the number of the accommodating spaces 11, and the number of the openings 134 provided to the servers in each second air guiding groove 13 is the same as the number of the servers provided in the corresponding accommodating space 11.
In some embodiments, a plurality of openings 134 facing the server may be provided, and each opening 134 may be closed by a partition before being used, and only when the opening 134 needs to be used, the partition is removed again, and the unused opening 134 continues to be closed by the partition.
In some embodiments, the partition may be electronically controlled by the controller 14 or may be mechanically and physically removably attached to the opening 134.
In some embodiments, the controller 14 shown in fig. 1 may further include a temperature sensor for detecting the ambient temperature and a control switch configured to control the windshield 132 and the cooling device 15.
In some embodiments, the control switch is configured to control the wind deflector 132 to close the wind inlet 131 and simultaneously activate the cooling device 15 in response to the temperature sensor detecting that the outside temperature is greater than a preset temperature.
In some embodiments, the control switch is further configured to control the wind deflector 132 to close the opening 133 facing the wind outlet 121 and simultaneously close the cooling device 15 in response to the temperature sensor detecting that the outside temperature is less than a preset temperature.
In some embodiments, as shown in fig. 2, when the temperature sensor detects that the outside temperature is greater than the preset temperature, the cooling device 15 is required to dissipate heat, and the control switch controls the wind deflector 132 to rotate in the direction of the dotted arrow to close the wind inlet 131 and simultaneously open the cooling device 15, as shown in the top view of the second wind guiding groove 13. After the air inlet 131 of the second air guiding groove 13 is closed, the outside hot air can be prevented from entering the inside of the cabinet 1 through the second air guiding groove 13, and meanwhile, since the opening 133 of the air outlet 121 facing the first air guiding groove 12 is opened, the cold air generated by the refrigerating device 15 can enter the second air guiding groove 13 through the opening 133 of the air outlet 121 facing the first air guiding groove 12 on the side of the second air guiding groove 13, and then enter the air inlet of the server through the opening 134 facing the server.
As shown in fig. 3, which is a schematic view of the wind deflector 132 after rotating along the dotted line to close the wind inlet 131, in order to control the wind deflector 132 to rotate, an electric rotating shaft 135 may be provided, and the controller 14 controls the electric rotating shaft 135, and thus the wind deflector 132 to rotate.
When the temperature sensor detects that the outside temperature is lower than the preset temperature, concentrated heat dissipation may be adopted, and at this time, the control switch controls the wind deflector 132 to rotate in the direction of the solid arrow to close the opening 133 facing the first wind guiding groove 12, and simultaneously turn off the cooling device 15. After the air inlet 131 of the second air guiding groove 13 is opened, the external cold air can enter the second air guiding groove 13 through the air inlet 131 of the second air guiding groove 13, and meanwhile, because the opening 133 facing the air outlet 121 of the first air guiding groove 12 is closed, the external cold air cannot enter the first air guiding groove 12, but enters the air inlet of the server through the opening 133 facing the air inlet of the server on the side of the second air guiding groove 13.
In some embodiments, the refrigeration device 15 shown in fig. 1 and connected to the controller 14 and the first air guiding groove 12 mainly includes a small compressor (hereinafter, referred to as a compressor), a condenser, a blower, and the like. When the switch is triggered by the intelligent control device, the compressor starts to absorb the air flow higher than the temperature threshold value from the outside of the cabinet 1, the high-temperature air flow is cooled after passing through the condenser, and the cold air flow is blown into the first air guide groove 12 through the blower.
In some embodiments, the server cabinet 1 may further include a plurality of longitudinally extending third air guiding grooves disposed in the cabinet, each of the third air guiding grooves is provided with an air outlet and an air baffle at two ends, and is provided with an opening facing the air outlet of the server at a side surface and controls the cooling device 15 accordingly.
Therefore, cold air is sucked into the server at the air inlet of the server to absorb heat and become hot air, and then the hot air is discharged through the air outlet of the server, and the hot air discharged through the air outlet of the server enters the third air guide groove through the opening on the side surface of the third air guide groove facing the air outlet of the server and finally is discharged out of the cabinet 1 through the air outlets at the two ends of the third air guide groove.
The number of the third air guiding grooves is the same as that of the accommodating spaces 11, and the number of the openings provided to the servers in each third air guiding groove is the same as that of the servers provided in the corresponding accommodating space 11. The structure of the third air guiding groove is basically the same as that of the second air guiding groove 13, and the difference is only that the side surface of the second air guiding groove 13 is provided with an opening facing the air outlet of the first air guiding groove 12, and the third air guiding groove is only provided with an opening facing the air outlet of the server.
In some embodiments, the controller 14 is further configured to control the wind deflector of the third wind-guiding groove to close or open the wind inlet of the third wind-guiding groove.
In some embodiments, the plurality of longitudinally extending third air guiding slots are disposed at a position opposite to the front door of the cabinet 10.
The server cabinet 1 provided in the embodiment of the present invention can close the air inlet 131 or the opening 133 facing the air outlet 121 through the external temperature detected by the controller 14, so that the cabinet 1 can dissipate heat through the second air guiding groove 13 during centralized heat dissipation, and also can dissipate heat through the first air guiding groove 12 and the refrigerating device 15 during a centralized heat dissipation failure. Therefore, the effect of concentrated heat dissipation can be guaranteed, and the problems of server downtime or restarting caused by concentrated heat dissipation faults and high temperature can be avoided.
