Description

Technical Field

[0001] This application relates to the field of data center cooling technology, and in particular to a smart data center cooling system. Background Technology

[0002] With the introduction of the national new infrastructure and the East-West computing strategy, the data center industry has seen many benefits. However, the rapid development of data centers has also brought about the problem of high energy consumption. Therefore, the requirements for PUE (Power Usage Effectiveness) indicators of data centers are constantly being lowered.

[0003] Servers generate a significant amount of heat during operation. Since data center server rooms are enclosed spaces, this heat cannot dissipate naturally, necessitating specialized cooling systems. Traditional cooling systems employ mechanical refrigeration. During this process, compressors operate, using various types of refrigerants as carriers to transfer the substantial heat generated within the data center from inside the server room to the outside, thereby cooling the room.

[0004] However, traditional cooling methods require waiting until the server room temperature has already risen before starting to cool down, by which time the server has already reached a high temperature, causing frequent fluctuations in server temperature and affecting operational stability.

[0029] like Figure 1 As shown in the figure, this application provides a data center intelligent cooling system, including a control device 1, an indoor cooling device 2, a natural cooling device 3, and a mechanical cooling device 4.

[0030] The computing control unit 1 includes: a computer room temperature acquisition device, a server temperature acquisition device, and a controller. The computer room temperature acquisition device and the server temperature acquisition device are temperature sensors. The computer room temperature acquisition device is installed inside the computer room, and the server temperature sensor is installed on a rack or directly on the server. The controller connects to the computer room temperature acquisition device and the server temperature acquisition device to acquire computer room temperature data and server temperature data. The computing control module 1 may also include a traffic statistics device, which is installed on the server and connected to the controller to send server traffic data to the controller. Typically, since the server itself can have traffic statistics functionality, the controller can also be directly connected to the server, allowing the server to perform traffic statistics and send the data to the controller.

[0031] The indoor cooling unit 2 includes an indoor air conditioner.

[0032] like Figure 3 As shown, the natural cooling device 3 includes at least one set of natural cooling units 301. When the number of natural cooling units is greater than or equal to two sets, the natural cooling units 301 are connected in parallel. The natural cooling unit includes a generator, a condenser, an evaporator, an absorber, a circulating pump, and a throttle valve installed in series.

[0033] like Figure 4As shown, the mechanical cooling device 4 includes at least one set of mechanical cooling units 401. When the number of mechanical cooling units 401 is greater than or equal to two sets, the mechanical cooling units 401 are connected in parallel. The mechanical cooling unit includes a fan and a condenser, with the fan positioned above the condenser.

[0034] The liquid outlet of the indoor cooling device 2 is connected to the liquid inlet of the natural cooling device 3, the liquid outlet of the natural cooling device 3 is connected to the liquid inlet of the mechanical cooling device 4, and the liquid outlet of the mechanical cooling device 4 is connected to the liquid inlet of the indoor cooling device 2.

[0035] like Figure 2 As shown, in an optional embodiment, the liquid outlet of the indoor cooling device 2 is also connected to the liquid inlet of the mechanical cooling device 4.

[0036] like Figure 4 As shown, in an optional embodiment, the mechanical cooling device 4 further includes a two-way valve 402, which is connected in parallel with the mechanical cooling unit 401.

[0037] The computing control device 1 is connected to the computer room temperature acquisition device, the server temperature acquisition device, and the server, respectively, to acquire computer room temperature data, server temperature data, and server traffic data, and controls the natural cooling device 3 and the mechanical cooling device 4 to adjust the computer room temperature based on the computer room temperature data, server temperature data, and server traffic data.

[0038] When the intelligent cooling system for data centers of this application is in operation, the computing control device 1 collects real-time data on the computer room temperature through a computer room temperature acquisition device installed in the computer room. Then, based on the real-time data on the computer room temperature, it controls the opening or closing of the natural cooling device 3 and / or the mechanical cooling device 4 outside the computer room. The natural cooling device 3 and / or the mechanical cooling device 4 cool the coolant, and then the cooled coolant is delivered to the indoor cooling device 2 inside the computer room to cool the computer room.

[0039] In this application, when the computer room temperature is low, the computing control device 1 can open the natural cooling device 3, close the mechanical cooling unit 401 in the mechanical cooling device 4, and open the two-way valve 402. This allows the computer room temperature to be regulated solely by the natural cooling device 3. When the computer room temperature is high, the computing control device 1 can close the natural cooling device 3, open the mechanical cooling unit 401 in the mechanical cooling device 4, and close the two-way valve 402. This allows the computer room temperature to be regulated solely by the mechanical cooling device 4. Alternatively, the computing control device 1 can simultaneously open both the natural cooling device 3 and the mechanical cooling unit 401 in the mechanical cooling device 4, and close the two-way valve 402. This allows both the natural cooling device 3 and the mechanical cooling device 4 to be used simultaneously for further regulation of the computer room temperature.

[0040] While cooling the data center based on real-time temperature data, the computing control device 1 also acquires server temperature data through a server temperature acquisition device and server traffic data through a traffic statistics device (or directly through the server), and sends these data to the controller. After acquiring the server temperature and traffic data, the controller records the acquisition time. Then, it statistically analyzes the server temperature and traffic data according to a preset time period and records the corresponding time intervals. For example, it can use an hourly time period to statistically analyze the average server temperature and total traffic data for each hour, and then record the average server temperature and total traffic data for each hour of the day. In this way, when the same time arrives on the second day, the controller can directly control the natural cooling and mechanical cooling devices to turn on or off without relying on real-time data center temperature data, thus starting cooling before the data center temperature rises. After pre-adjusting the data center temperature based on server temperature and traffic data, the controller can continue to adjust the data center temperature in real-time based on the actual real-time temperature data.

[0041] For example, the controller collected data showing a server temperature of 50℃ and server traffic of 100M from 18:01 to 19:00 on January 1st, and a server temperature of 60℃ and server traffic of 300M from 19:01 to 20:00 on January 1st. It can be seen that the server temperature may rise compared to the previous hour due to increased user access during the 19:01-20:00 hour. Therefore, at 19:01 on January 2nd, the controller can directly activate the natural cooling or mechanical cooling system to cool the server room. Since the server room temperature rises after the server temperature has risen, cooling the server room after the server temperature has already reached a certain level will cause significant fluctuations in server temperature. Since server temperature rise is related to the server's operating status, directly adjusting the server room temperature based on server temperature and traffic data allows for more timely temperature control, ensuring server temperature is managed even with minor fluctuations and maintaining server stability.

[0042] Understandably, the controller can use server temperature data and server traffic data from the same time period of the previous day as the standard for adjusting the temperature, or it can use server temperature data and server traffic data from the same time period of several days ago as the standard for adjusting the temperature. This application does not make any specific limitations here.

[0043] In this embodiment, the data center intelligent cooling system includes a control device, an indoor cooling device, a natural cooling device, and a mechanical cooling device. The control module includes a computer room temperature acquisition device, a server temperature acquisition device, and a computing control device. The liquid outlet of the indoor cooling device is connected to the liquid inlet of the natural cooling device, the liquid outlet of the natural cooling device is connected to the liquid inlet of the mechanical cooling device, and the liquid outlet of the mechanical cooling device is connected to the liquid inlet of the indoor cooling device. The computing control device is connected to the computer room temperature acquisition device, the server temperature acquisition device, and the server, respectively, to acquire computer room temperature data, server temperature data, and server traffic data, and controls the natural cooling device and the mechanical cooling device to adjust the computer room temperature based on the computer room temperature data, server temperature data, and server traffic data. This application can start cooling the computer room before the temperature rises based on the server temperature and server traffic, thereby avoiding frequent fluctuations in server temperature and improving server operational stability.
