As shown in fig. 3 to 5, according to another aspect of the present invention, there is provided a server system including a cabinet 400 provided with a server 300 and a flow guide assembly provided at a front end of the cabinet 400, the flow guide assembly being the flow guide assembly in the above embodiment.
Set up the water conservancy diversion subassembly through the front end at rack 400, carry out the water conservancy diversion to the cooling air in the cold wind passageway of rack 400 front side, towards rack 400 when making the cooling air flow out from the water conservancy diversion subassembly to strengthen the pressure of rack 400 department, in order to prevent hot-blast backward flow in the hot-blast passageway and influence the cooling effect in the cold wind passageway, thereby avoided existing among the prior art because the sensor that hot-blast backward flow leads to detects the high temperature, cause the high temperature to report an emergency and ask for help or increased vigilance, cause the problem of server energy consumption.
Optionally, as shown in fig. 5, in this embodiment, the cabinet 400 includes a cabinet housing, at least one server 300 is disposed in the cabinet housing, a gap 500 is provided between the server 300 and the cabinet housing (for example, the gap 500 between the right edge of the server 300 and the right edge of the cabinet 400 indicated in fig. 5) so as to facilitate the detachment and installation of the server 300, the flow guide assembly is disposed on the cabinet housing, and the fluid outlet 104 of the flow guide assembly faces the gap 500 so as to increase the pressure at the gap 500 of the cabinet, avoid backflow of hot air through the gap 500, and prevent the problem of overhigh detection temperature caused by backflow of hot air.
In the present embodiment, the server 300 includes a server hanging lug 302, the server hanging lug 302 is disposed on the cabinet shell and corresponds to the fluid outlet 104, and a temperature sensor 3021 for detecting the temperature of the corresponding server 300 is disposed on the server hanging lug 302.
The server hangers 302 are used to mount a temperature sensor 3021 and the like. The temperature sensor 3021 is used to detect the temperature of the server 300, so that the server 300 can control its own cooling structure (e.g., cooling fan) according to the detected temperature, for example, to increase or decrease the power of the cooling structure.
As shown in fig. 3 and 4, since the server hangers 302 are disposed corresponding to the fluid outlets 104 of the airflow guiding assemblies, the cooling air flowing out from the fluid outlets 104 can blow the temperature sensors 3021 disposed on the server hangers 302, so as to reduce the temperature detected by the temperature sensors 3021, and make the detected temperature closer to or consistent with the actual temperature of the server 300, thereby avoiding the problem that in the prior art, because the hot air may flow back to the cold air channel from the gap 500 between the server 300 and the cabinet 400, and the temperature sensors are on the path of the hot air flowing back, the detected temperature is higher than the actual temperature of the server, and the cooling structure on the server always operates at a higher frequency, which results in huge energy consumption.
According to another aspect of the present invention, there is provided a data center including the server system described above. The data center using the server system can avoid the hot air backflow phenomenon existing in the existing server system due to the fact that the flow guide assembly is arranged on the server system, and can reduce the deviation value between the temperature detected by the temperature sensor and the actual temperature of the server, so that the problems that the server is easy to alarm at high temperature and has high energy consumption in the prior art are solved.
The process that the data center with the air guide assembly cools the server through cooling air is as follows:
because the air guide assembly is installed at the front end of the cabinet 400 and is located in the cool air channel, the cooling air in the cool air channel enters the flow channel 106 from the fluid inlet 102 of the air guide assembly in the flowing process, is reversed in the flow channel 106 and flows out from the fluid outlet 104 to be blown to the cabinet 400, so that the pressure at the position of the cabinet 400 is increased, and the hot air is prevented from flowing back from the gap 500. From this, the temperature sensor who exists has been solved and has been located hot-blast backward flow department among the prior art, and detection temperature is too high, appears the problem of spurious triggering high temperature warning easily, reduces server 300's consumption, makes every rack save 300W power loss at least, through set up this water conservancy diversion subassembly at rack 400 front end, can reduce the difference in temperature between detection temperature and the server actual temperature, reduces to the 2 ℃ of difference in temperature by the 10 ℃ of difference in temperature among the prior art, can make both keep unanimous even.
It should be noted that, according to the implementation requirement, each component/step described in the embodiment of the present invention may be divided into more components/steps, and two or more components/steps or partial operations of the components/steps may also be combined into a new component/step to achieve the purpose of the embodiment of the present invention.
