Description

Technical Field

[0002] This section merely provides background information related to the present disclosure and is not necessarily prior art.

[0003] In recent years, as the infrastructure of the Internet, big data, AI cloud computing and other industries, data centers have also experienced explosive growth. In data centers, the efficient, reliable and stable operation of air conditioning systems is crucial to ensuring data security. As the core element of temperature control in air-cooled data centers, airflow organization plays a decisive role in maintaining the safety and stable operation of computer rooms, achieving energy efficiency and reducing energy consumption.

[0004] At present, the optimization of airflow organization for data centers is mainly the optimization of the under-floor air supply form.

By setting shutters and partition walls under the raised floor to form a collection area, and controlling the air conditioning wind and shutters through temperature sensors, the distribution of cold in the closed channel is realized. This prior art can optimize the airflow organization of under-floor air supply, but is not suitable for the airflow organization form of the wind wall of the data center. CN201720963175.1 is a data center system with a wind wall structure. This prior art designs a wind wall system for use in a data center, and sets a guide plate at the vent to control the blowing direction of the air conditioning fan. This prior art can realize the airflow regulation of the channel, but has no regulation capability for the airflow entering the cabinet and the above-mentioned prior art all uses temperature sensors for regulation, which lags behind the service and chip heating time, affecting the cooling effect.

DETAILED DESCRIPTION

[0048] The present invention proposes a cabinet with a guide baffle based on a digital twin model and a control method thereof. The overall design idea is as follows: by setting an angle-adjustable baffle on the cabinet, more cooling airflow is guided into the cabinet. At the same time, adjustable shutters are arranged in partitions on the adjustable baffle, and the cooling airflow is guided by opening and closing the shutters in different areas; based on the digital twin model of the data room, the steady-state temperature field is predicted in real time according to the changes in server load, and the baffle angle and the opening and closing of the shutters are adjusted.

[0049] In one embodiment, Figure 1 As shown, a cabinet with a guide baffle based on a digital twin model is provided with: a first group of adjustable shutters 11 consisting of adjustable shutters I, adjustable shutters II, adjustable shutters III, adjustable shutters IV, and adjustable shutters V; a second group of adjustable shutters 12 consisting of adjustable shutters VI, adjustable shutters VII, adjustable shutters VIII, adjustable shutters IX, and adjustable shutters X; a third group of adjustable shutters 13 consisting of adjustable shutters XI, adjustable shutters XII, adjustable shutters XIII, adjustable shutters XIV, and adjustable shutters XV; an intelligent control submodule I, an intelligent control submodule II, and an intelligent control submodule III forming an intelligent control module 2; and a server group 4 and a server cabinet 5 consisting of an adjustable baffle 3, a server I, a server II, a server III, a server IV, a server V, and a server VI;

[0050] The first group of adjustable louvers is connected to the intelligent control submodule I through a transmission device, the second group of adjustable louvers is connected to the intelligent control submodule II through a transmission device, and the third group of adjustable louvers is connected to the intelligent control submodule III through a transmission device; the adjustable baffle 3 is installed on the front of the server cabinet 5, and the intelligent control module 2 is installed between the adjustable baffle 3 and the server cabinet 5; the server I, server II, server III, server IV, server V, and server VI are all installed in the server cabinet 5;

[0051] According to the above cabinet with air guide baffle based on digital twin model, a digital twin model is constructed to control it. The airflow organization simulation model of the digital twin model is based on computational fluid dynamics (CFD), and the prediction model is based on the proper orthogonal decomposition (POD) method.

[0052] like Figure 2 As shown, when the average air outlet temperature of the servers in the cabinet is not higher than the set temperature value, the angle α between the adjustable baffle 3 and the cabinet 5 is 90°, and the first, second and third groups of adjustable louvers are all kept parallel to the ground;

[0053] According to the prediction results of the digital twin model, when the predicted average air outlet temperature of the server in the cabinet exceeds the set temperature value by 3°C, the intelligent control module IV drives the adjustable baffle 3 to move so that the angle α between the adjustable baffle 3 and the server cabinet 5 is 60°;

[0054] When the digital twin model predicts that the air outlet temperature of server I, server II, server III, server IV, server V11, and server VI exceeds the set temperature by 3°C, the first, second, and third groups of blinds are kept closed;

[0055] When the digital twin model predicts that the temperature of server I and server II does not exceed the threshold, the intelligent control submodule I opens the first set of adjustable shutters to keep the shutters parallel to the ground. When the digital twin model predicts that the air outlet temperature of server III and server IV does not exceed the threshold, the intelligent control module II opens the second set of adjustable shutters to keep the shutters parallel to the ground. When the digital twin model predicts that the temperature of server V and server VI does not exceed the threshold, the intelligent control module III opens the third set of adjustable shutters to keep the shutters parallel to the ground.

[0056] like Figure 3 As shown, the digital twin model consists of an airflow organization simulation model and a prediction model; the airflow organization simulation model consists of a geometric model, a thermal model, and an airflow model. The geometric model is a virtual model of the equipment in the computer room and is the calculation basis for the thermal model and the airflow model; the thermal model is a set of temperature parameters of the thermal environment in the computer room after the airflow organization simulation, including the heat generated by the equipment, the temperature field distribution in the hot and cold channels and in the ceiling, and the air conditioning supply and return air temperature; the airflow model is a set of wind speed distribution in the computer room after the airflow organization simulation, including the cabinet inlet and outlet wind speed, the wind speed in the hot and cold channels and in the ceiling, and the air conditioning supply and return wind speed;

[0057] The control process of the cabinet with guide baffle is as follows:

[0058] Step S1: monitor the real-time load of the server and update the digital twin model to reflect the current working status of the server;

[0059] Step S2: Use the digital twin model to predict possible hot spots inside the server cabinet;

[0060] Step S3: automatically adjusting the baffles in the cabinet according to the hot spot prediction result to optimize the airflow distribution and reduce the temperature of the hot spot area;

[0061] Step S4: Feedback the baffle position information to the digital twin model, verify the effect of the baffle adjustment through airflow organization simulation, ensure that the temperature control reaches the expected target, and make further adjustments as needed.

[0062] Example:

[0063] like Figure 4 As shown, this embodiment proposes a cabinet control method with a guide baffle based on a digital twin model, and its control process is as follows:

[0064] Step S1: monitor the real-time load of the server and update the digital twin model to reflect the current working status of the server;

[0065] Step S2: Use the digital twin model to predict possible hot spots inside the server cabinet;

[0066] Step S3: automatically adjusting the baffles in the cabinet according to the hot spot prediction result to optimize the airflow distribution and reduce the temperature of the hot spot area;

[0067] Step S4: Feedback the baffle position information to the digital twin model, verify the effect of the baffle adjustment through airflow organization simulation, ensure that the temperature control reaches the expected target, and make further adjustments as needed.

[0068] like Figure 3 As shown in the figure, the digital twin model consists of an airflow organization simulation model and a prediction model; the airflow organization simulation model consists of a geometric model, a thermal model, and an airflow model; the prediction model reduces the order of the temperature field solved by the finite element method based on the intrinsic orthogonal method, extracts key modes from it, and constructs a reduced-order model. The reduced-order model is used for real-time simulation to quickly respond to operational changes in the data center, and is combined with the operating parameters of the data center computer room for machine learning to realize the simulation and prediction of data center hotspots by the prediction model.

[0069] In one embodiment, the geometric model parameters of the computer room include the height, area, return air space in the ceiling, width of the air-conditioning room, size of the air supply equipment hole, cabinet installation position, air-conditioning installation position, width of hot and cold channels, size and position of power supply equipment, size and position of air-conditioning water duct and air duct, size and position of beams and columns in the computer room; cabinet parameters include cabinet size, server size and installation position, and server power consumption under different loads; air-conditioning parameters include air-conditioning size, rated cooling capacity, rated air volume, rated power consumption, and corresponding cooling capacity and air volume under different loads; and also include property parameters of object materials and computer room boundary condition parameters.

[0070] Specifically, Figure 5 As shown, it is a model diagram of the airflow organization of the cabinet with guide baffles applied to the wind wall air supply form of the data center. The above-mentioned computer room geometric model parameters are input into the CFD software to establish the airflow organization simulation model of the computer room. When the wind wall is for double-sided air supply, the middle cabinet of a row of cabinets is used as the boundary, and the guide baffles of the cabinets on both sides are respectively facing the air supply directions on both sides.

[0071] At present, the optimization of airflow organization for cabinets is mainly aimed at the form of under-floor air supply, and there are fewer optimizations for airflow organization in the form of air wall air supply. Most of the airflow control methods in the computer room of the data center control the air supply volume and cooling capacity of the air conditioner through the supply and return air temperature. Similar methods of controlling the supply airflow through automation are also mostly based on the inlet and outlet temperatures of the cabinet. The control of these methods is based on the increase in the server load, the increase in the server temperature, which leads to the increase in the outlet temperature. After the sensor detects the temperature increase, it provides feedback and the corresponding equipment takes corresponding actions. This process is relatively lagging, and the sensor detection accuracy is also affected by various equipment in the actual operation process, resulting in feedback errors. This solution provides a cabinet with guide baffles based on a digital twin model, which is suitable for the wind wall air supply form of the data center. The digital twin model based on the airflow organization simulation model and the prediction model is used to simulate and predict the operating status of the data center. It quickly gives feedback when the server load changes, adjusts the cabinet guide baffles and shutters, and updates the model information to the airflow organization simulation model. The airflow organization simulation model compares the simulated server inlet and outlet temperatures with the parameters obtained by the actual sensor to determine whether the existing cabinet baffles and shutters meet the server operation requirements, and further deepens the adjustment of the guide baffles and shutters.

[0072] In a specific implementation, the present application provides a computer storage medium and a corresponding data processing unit, wherein the computer storage medium can store a computer program, and when the computer program is executed by the data processing unit, the invention content of a cabinet with a guide baffle based on a digital twin model and a control method thereof provided by the present invention and some or all steps in each embodiment can be run. The storage medium can be a disk, an optical disk, a read-only memory (ROM) or a random access memory (RAM), etc.

[0073] Those skilled in the art can clearly understand that the technical solutions in the embodiments of the present invention can be implemented by means of computer programs and their corresponding general hardware platforms. Based on such an understanding, the technical solutions in the embodiments of the present invention can be essentially or partly contributed to the prior art in the form of computer programs, i.e., software products, which can be stored in a storage medium and include several instructions for enabling a device including a data processing unit (which can be a personal computer, a server, a single-chip microcomputer, an MCU or a network device, etc.) to execute the methods described in various embodiments of the present invention or certain parts of the embodiments.

[0074] The present invention provides a cabinet with a guide baffle based on a digital twin model and a control method thereof. There are many methods and ways to implement the technical solution. The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
