Description

TECHNICAL FIELD

[0001] The present application relates to the field of data centers, in particular to a cold plate liquid cooling system, an adaptive energy-saving operation control method and device thereof, computer equipment and a computer readable storage medium. BACKGROUND

[0002] In recent years, technologies such as big data, cloud computing, and artificial intelligence have developed rapidly, and the IT heat dissipation density has increased rapidly. Because the cold plate liquid cooling technology can solve the problem of high heat flow heat dissipation density and system high efficiency and energy saving, it meets the national development strategy of digital China and carbon neutralization, so the cold plate liquid cooling technology has developed rapidly. Because the cold plate liquid cooling technology does not use traditional data center water chillers, cold storage facilities, and terminal air conditioners, the largest energy-consuming equipment in the cold plate liquid cooling system is the circulating water pump that runs continuously. Therefore, how to optimize the system pipeline and pump operation condition under the premise of meeting the heat dissipation demand of the terminal information equipment has become an important problem for the energy saving and consumption reduction of the cold plate liquid cooling system.

[0003] For the cold plate liquid cooling technology, the conventional cold plate liquid cooling secondary side controls the water pump operation frequency by setting the pressure difference, or directly uses the set flow mode to run. In some IT load conditions, the actual running flow of the system is greater than the required flow of the system, and the mismatch between the supply and demand of the running flow will reduce the running efficiency of the cold plate liquid cooling system, which is not conducive to the safe and energy-saving operation of the cold liquid cooling system. In other words, in the conventional cold plate liquid cooling, the cold plate liquid cooling secondary side is usually controlled by setting the pressure difference and the flow rate, and the mismatch between the supply and demand of the running flow reduces the running efficiency.

[0086] The following first introduces the cold plate liquid cooling system and its adaptive energy-saving operation control method and device of the present application in combination with the related technologies of the present application, and then provides multiple embodiments for realizing the technical solutions described below.

[0087] The conventional cold plate liquid cooling has the following disadvantages:

[0088] (1) The conventional cold plate liquid cooling controls the water pump operation frequency through the constant pressure difference at the secondary side, or directly adopts the constant flow mode operation, and in some IT load working conditions, the actual operation flow of the system is much larger than the required flow of the system, and the mismatch between the operation flow supply and demand will reduce the operation efficiency of the liquid cooling system, which is not conducive to the safe and energy-saving operation of the liquid cooling system.

[0089] (2) The key parameters of the conventional cold plate liquid cooling control system need to be manually adjusted according to experience after the design and test are completed, and cannot be adaptively adjusted according to the actual heat dissipation demand of electronic information equipment, and when facing the heat dissipation demand changes of rapidly iterated and upgraded electronic information equipment, the adaptability and compatibility of the cold plate liquid cooling system are insufficient.

[0090] In view of these shortcomings, the purpose of the present application and the technical effects that can be achieved are explained.

[0091] This application proposes a cold plate liquid cooling system and its adaptive energy-saving operation control method and device. The system settings parameters are continuously optimized based on the operating temperature of key server components and the power consumption of the server rack. This solves the high energy consumption problem caused by the mismatch between the supply and demand of the operating flow of constant differential pressure control and constant flow control. It helps the cold plate liquid cooling system to meet the heat dissipation needs of electronic information equipment more accurately and on a larger scale, and ensures the safe and energy-saving operation of the liquid cooling system.

[0092] The protection points and technical effects of this application are as follows:

[0093] (1) By adding data such as the operating temperature of key server components and the power consumption of server cabinets, the preset adaptive energy-saving optimization algorithm is used to continuously optimize the set value of the cabinet return water temperature and the set value of the differential pressure at the end of the main loop pipe, which effectively solves the problem of low operating efficiency due to the mismatch between the supply and demand of the constant differential pressure control and constant flow control on the secondary side of the cold plate liquid cooling.

[0094] (2) Under the premise of meeting the requirements of the cabinet terminal, adjust the number of CDU units in operation and the operating frequency of their internal circulating water pumps to ensure the safe and energy-saving operation of the liquid cooling system.

[0095] Several embodiments will be provided below, which can be used to implement the above description. Cold plate liquid Cold system and adaptive energy-saving operation control method and device thereof To facilitate understanding, the following will use... Cold plate liquid cooling system An exemplary description is provided for the implementing entity.

[0096] Example 1

[0097] Figure 1 The schematic diagram illustrates the overall architecture of a cold plate liquid cooling system according to Embodiment 1 of this application.

[0098] As an example, a cold plate liquid cooling system includes multiple server racks (e.g.: Figure 1 Multiple racks in the system), CDU units (e.g.: Figure 1 The server rack contains CDU1, CDU2, CDU3, and CDU4, the first ring pipe 10, and the second ring pipe 20. Each server rack houses multiple servers. Figure 1 (Not shown). The ends of the first loop pipe 10 and the second loop pipe 20 are the main loop pipe ends. Cold water from the first loop pipe 10 flows into the multiple server racks through multiple rack water supply pipes 30, each rack water supply pipe 30 being equipped with an electric regulating valve 31. The cold water undergoes heat exchange within the multiple server racks to obtain hot water, which then flows out through multiple rack return water pipes 40 to the second loop pipe 20. The hot water from the second loop pipe 20 flows into the CDU unit, where the CDU unit cools the hot water to obtain cold water, which then flows out back into the first loop pipe 10.

[0099] As an example, the plurality of servers placed in the server rack include server key components. In an illustrative embodiment of the present application, the server key components mainly include CPUs and GPUs. The server key components are units cooled by liquid cooling cold plates, and the purpose of the cold plate liquid cooling system control is to improve the operating efficiency of the cooling system while ensuring that the server key components operate at an appropriate temperature.

[0100] In other embodiments, the server key components can also include other components, such as memories, etc.

[0101] As an example, each rack return pipe 40 is provided with a temperature sensor 41 for collecting the actual operating temperature of the rack return pipe 40.

[0102] As an example, a differential pressure sensor (such as a DSP) is provided between the end of the first ring pipe 10 and the end of the second ring pipe 20, for collecting the actual operating differential pressure at the end of the main ring pipe in real time. Figure 1

[0103] As an example, the cold plate liquid cooling system further includes an adaptive energy-saving operation control device. In an illustrative embodiment of the present application, the adaptive energy-saving operation control device includes a controller 60 and a server rack monitoring platform, which cooperate to implement an adaptive energy-saving operation control method. Figure 1 Figure 1 In an illustrative embodiment of the present application, the controller 60 is connected to a plurality of server racks (such as Rack), CDU units (such as CDU1, CDU2, CDU3, CDU4), electric regulating valves 31, temperature sensors 41, and differential pressure sensors (such as DSP) through signal lines (such as weak signal lines of the controller 60). Figure 1 Figure 1 Figure 1

[0104] In other embodiments, if the controller 60 is a high-end controller with very good performance, the adaptive energy-saving operation control device can only include the controller 60 in the controller 60, and the adaptive energy-saving operation control method is implemented by the controller 60. Figure 1

[0105] Figure 2 An illustrative flowchart of an adaptive energy-saving operation control method according to an embodiment of the present application is shown.

[0106] As shown in Figure 2 The adaptive energy-saving operation control method in the present application can include steps S201-S211, wherein:

[0107] ​​​​​​Step S201 (as an optional step), initialize the cabinet return water temperature setting value T0 and the main ring pipe end pressure difference setting value ΔP0.

[0108] Step S203, real-time collection of the first actual operating temperature T of the plurality of cabinet return water pipes, adjustment of the opening degree of the electric regulating valve according to the deviation of the first actual operating temperature and the cabinet return water temperature setting value.

[0109] Step S205 (as an optional step), real-time collection of the actual operating pressure difference of the main ring pipe end; adjustment of the operating mode of the CDU unit according to the deviation of the actual operating pressure difference and the main ring pipe end pressure difference setting value; wherein the CDU unit cools down hot water to obtain cold water, and the cold water flows out to the first ring pipe.

[0110] Step S207, real-time collection of the second actual operating temperature t of the plurality of server key components.

[0111] Step S209 (as an optional step), when the second actual operating temperature t is not within the preset temperature range, resetting the cabinet return water temperature setting value T0 according to the second actual operating temperature.

[0112] Step S211, when the second actual operating temperature t is within the preset temperature range, but the opening degree of the electric regulating valve is not within the preset opening degree range, resetting the main ring pipe end pressure difference setting value ΔP0 according to the opening degree of the electric regulating valve and the second actual operating temperature. The main ring pipe end is the end of the first ring pipe 10 and the end of the second ring pipe 20, the first ring pipe 10 provides cold water for heat exchange, and the second ring pipe 20 is used to receive hot water obtained by heat exchange.

[0113] The cold plate liquid cooling system and the adaptive energy-saving operation control method and device thereof provided by the embodiment of the application can adaptively adjust and optimize (reset) the main ring pipe end pressure difference setting value ΔP0 according to the actual operating condition, effectively solve the problem of constant pressure difference control and constant flow control of the secondary side of the cold plate liquid cooling, and the problem of low operating efficiency due to the mismatch between supply and demand of operating flow. Further, based on the optional step S201, the cabinet return water temperature setting value T0 and the main ring pipe end pressure difference setting value ΔP0 can be initialized in advance through inspection value or pre-operation. Based on the optional step S205, the operating mode of the CDU unit is adjusted to achieve energy saving. Based on the optional step S207, the cabinet return water temperature setting value T0 is adaptively adjusted and optimized (reset) according to the actual operating condition, further solving the problem of constant pressure difference control and constant flow control of the secondary side of the cold plate liquid cooling, and the problem of low operating efficiency due to the mismatch between supply and demand of operating flow.

[0114] As an example, as shown in Figure 3 , the cabinet return water temperature setting value T0 and the main ring pipe end pressure difference setting value ΔP0 are initialized in advance through inspection value or pre-operation. Figure 2Step S201 may include step S301. Specifically: Step S301 involves initializing and setting the rack return water temperature setpoint T0 and the main loop pipe end pressure differential setpoint ΔP0 under a test scenario where multiple server racks are at full load.

[0115] As an example, the setpoint T0 for the return water temperature of the server rack and the setpoint ΔP0 for the differential pressure at the end of the main loop pipe can be determined based on the server's cold plate heat dissipation design.

[0116] pass Figure 3 The process involves setting the safest operating conditions and maximum power consumption under full-load test scenarios, and setting the safest cabinet return water temperature setpoint T0 and the main loop pipe end pressure difference setpoint △P0 (derived from the design value) to ensure the safe operation of the cold plate liquid cooling system.

[0117] As an example, the first actual operating temperature T of the multiple cabinet return water pipes can be actually acquired by the temperature sensor. After acquiring the first actual operating temperature T of the multiple cabinet return water pipes, as follows: Figure 4 As shown, Figure 2 Step S203 may include steps S401 to S403. Specifically: Step S401, when the first actual operating temperature T is greater than the set value of the cabinet return water temperature, the opening of the electric regulating valve is increased, wherein the opening range of the electric regulating valve has a safety range; Step S403, when the first actual operating temperature T is less than the set value of the cabinet return water temperature, the opening of the electric regulating valve is decreased, wherein the opening range of the electric regulating valve has a safety range, such as within a set F... min and F max between.

[0118] pass Figure 4 The process can adaptively adjust the opening of the electric regulating valve based on the deviation between the first actual operating temperature T and the set value of the rack return water temperature, thereby achieving energy saving while meeting the needs of the server rack.

[0119] In an exemplary embodiment of this application, in Figure 4 In the flowchart, a safety range can be set for the valve opening adjustment range, that is, there is a safety threshold for adjusting it larger or smaller, which can avoid safety hazards caused by too small a flow rate.

[0120] As an example, a differential pressure sensor is provided between the end of the first loop and the end of the second loop (e.g.: Figure 1 In the DSP (Digital Signal Processor), the actual operating differential pressure at the end of the main loop pipe can be acquired in real time by the differential pressure sensor. Figure 5 As shown, Figure 2The step S205 can include a step S501 of adjusting the number of CDU units in operation and the frequency of water pump in operation according to the deviation of the actual operating differential pressure from the set value of the end differential pressure of the main loop.

[0121] Through the process of Figure 5 , the number of CDU units in operation and the frequency of water pump in operation can be adaptively adjusted according to the deviation of the actual operating differential pressure from the set value of the end differential pressure of the main loop, so as to realize energy saving under the premise of ensuring safe operation of the system.

[0122] As an example, as shown in Figure 6 , Figure 5 The step S501 can include a step S601. In the step S601, when the actual operating differential pressure is less than the set value of the end differential pressure of the main loop, the number of CDU units in operation and the frequency of water pump in operation are increased; and when the actual operating differential pressure is greater than the set value of the end differential pressure of the main loop, the number of CDU units in operation and the frequency of water pump in operation are decreased.

[0123] Through the process of Figure 6 , the number of CDU units in operation and the frequency of water pump in operation can be adaptively adjusted according to the deviation of the actual operating differential pressure from the set value of the end differential pressure of the main loop, so as to realize energy saving under the premise of ensuring safe operation of the system.

[0124] As an example, the plurality of server key components include CPU and GPU, as shown in Figure 7 , Figure 2 The step S207 can include a step S701. In the step S701, the second actual operating temperature of the plurality of server key components is read by the BMC on the plurality of server mainboards.

[0125] Through the step of Figure 7 , the second actual operating temperature of the plurality of server key components can be conveniently and quickly collected in real time.

[0126] As an example, as shown in Figure 8 , Figure 2 Further steps S801-S803 can be included. In the step S801, the power consumption of the plurality of server cabinets is collected in real time; and in the step S803, the system power consumption p is calculated according to a power consumption model.

[0127] As an example, the power consumption model is mainly a water pump power consumption model.

[0128] As an example, the system power consumption is described as follows: according to the known performance characteristic data of the selected water pump, the operating efficiency (η theoretical) under different CDU operating numbers (n), CDU internal circulating water pump operating frequencies (f), flow rates (V) and head (H) is determined, that is: η理论 = F(n, f, V, H), and through further system debugging, the actual operation (η actual) under different CDU operation numbers (n), CDU circulating water pump operation frequencies (f), flow rates (V), and lift (H) is determined and used to correct the operation efficiency theoretical model. Given the CDU operation number (n), CDU circulating water pump operation frequency (f), flow rate (V), and lift (H), and efficiency, the pump operation power, that is, the system power consumption, can be calculated.

[0129] Through the flow of Figure 8 , on the one hand, the server cabinet power consumption is collected in real time, which can ensure stable operation of the system. The embodiment of the present application realizes energy saving under the premise of ensuring system stability. On the other hand, the system power consumption is mainly for the reference of R&D personnel to show the system optimization effect, such as: the system power consumption is originally P1, and after one month of optimized operation, it becomes P2. The system optimization result can be seen through P1 and P2. If the adjustment method of the adaptive energy-saving operation control method of the present application is effective, the actual system power consumption will be reduced. If the actual system power consumption cannot be reduced after adjustment, the adjustment will be abandoned.

[0130] As an example, as shown in Figure 9 , Figure 8 , step S801 can include step S901. In step S901, the power consumption of the plurality of server cabinets is acquired through the power distribution unit (PDU) connected to the plurality of server cabinets.

[0131] Through the step of Figure 9 , the power consumption of the plurality of server cabinets can be conveniently and quickly collected.

[0132] As an example, as shown in Figure 10 , Figure 2 , step S209 can include steps S1001-S1005. In step S1001, when a part of the second actual operation temperatures t of the plurality of server key components is less than or equal to the minimum value of the preset temperature range, a part of the temperatures is in the preset temperature range, or all the temperatures are less than or equal to the minimum value of the preset temperature range, the cabinet return water temperature set value is increased by the preset temperature increment; when any temperature of the second actual operation temperatures t of the plurality of server key components is greater than or equal to the maximum value of the preset temperature range, the cabinet return water temperature set value is decreased by the preset temperature increment; in step S1003, the preset time is run, and the second actual operation temperatures t of the plurality of server key components are collected in real time; in step S1005, when the second actual operation temperatures t are all in the preset temperature range, the adjusted cabinet return water temperature set value T0 is taken as the newly set cabinet return water temperature set value T0.

[0133] In an exemplary embodiment of the present application, the preset temperature increment dT is set but unchanged during the adjustment process; when a part of the server temperature [t]≤t min , a part of t min ≤[t]≤t max , or all of the server temperature [t]≤t min , the return water temperature set value is increased, that is, T i+1 =T i +dT, for example: dT=0.1℃, T i =36.0, the above scenario occurs, then T i+1 =36.1; on the contrary, any one of the server temperature [t]≥t max , then T i+1 =35.9.

[0134] Through the flow of Figure 10 , according to the actual operation, the cabinet return water temperature set value is adaptively adjusted and optimized (reset), which effectively solves the problem of low running efficiency caused by the mismatch between the supply and demand of the running flow under the constant pressure difference control and constant flow control of the cold plate liquid cooling secondary side.

[0135] As an example, as shown in Figure 11 , Figure 10 the step S1003 can further include a step S1101. Wherein: step S1101, real-time acquisition of the power consumption of the plurality of server cabinets.

[0136] Through the steps of Figure 11 , the stable operation of the system can be ensured, and the energy saving of the embodiments of the present application is realized on the premise of ensuring the stability of the system.

[0137] As an example, as shown in Figure 12 , Figure 2Step S211 may include steps S1201 to S1205. Specifically: Step S1201: When a portion or all of the openings F of the electric regulating valve are less than the minimum value of a preset opening range, the differential pressure setting value ΔP0 at the end of the main loop pipe is reduced in units of the preset differential pressure increment; when any opening F of the electric regulating valve is greater than the maximum value of the preset opening range, the differential pressure setting value ΔP0 at the end of the main loop pipe is increased in units of the preset differential pressure increment; Step S1203: Run for a preset time and collect the second actual operating temperature t of the multiple server key components and the opening F of the electric regulating valve in real time; Step S1205: When a preset number of openings of the electric regulating valve are all within the preset opening range, the adjusted differential pressure setting value at the end of the main loop pipe is used as the reset differential pressure setting value at the end of the main loop pipe, wherein the preset temperature value is equal to the maximum value of the preset temperature range minus the redundant temperature value.

[0138] In an exemplary embodiment of this application, the preset differential pressure increment d(ΔP) is set but remains constant during adjustment; when the opening degree of some valves or all valves is less than F1, the differential pressure setting value, i.e., ΔP, is reduced. i+1 =ΔP i -d(ΔP), for example: d(ΔP)=0.15, ΔP i =7, if the above scenario occurs, then ΔP i+1 =6.85; conversely, if any valve opening is greater than F2, then ΔP i+1 =7.15. ΔP is the actual operating differential pressure at the end of the main loop pipe, which has a safe operating range. If controlled within the set ΔP... min and ΔP max between.

[0139] pass Figure 12 The process adaptively adjusts and optimizes (resets) the differential pressure setting value at the end of the main loop pipe based on the actual operating conditions, effectively solving the problem of low operating efficiency due to mismatch between the supply and demand of operating flow in the constant differential pressure control and constant flow control of the secondary side of the cold plate liquid cooling.

[0140] As an example, such as Figure 13 As shown, Figure 12 Step S1203 may further include step S1301. Specifically, step S1301 involves real-time collection of power consumption data from multiple server racks.

[0141] pass Figure 13 The steps taken can ensure the stable operation of the system. The embodiments of this application achieve energy saving while ensuring system stability.

[0142] Figure 14A specific flow chart of the adaptive energy-saving operation control method of the application is schematically shown.

[0143] As an example, the adaptive energy-saving operation control method in the embodiment of the application can include steps S1401-S1407.

[0144] Step S1401, initialize the setting of the cabinet return water temperature T0 and the terminal pressure difference △P0. As an example, the server key component operating temperature and the server cabinet power consumption are collected to determine the cabinet return water temperature setting value T0 and the main ring pipe terminal pressure difference setting value △P0.

[0145] Step S1402, adjust the cabinet water supply pipe electric regulating valve opening degree according to the deviation of the actual operating temperature from the setting value. As an example, the actual operating temperature of the cabinet return water pipe is collected in real time, and the cabinet water supply pipe electric regulating valve opening degree is adjusted according to the deviation of the actual operating temperature from the cabinet return water temperature setting value T0, to ensure that the server key components operate under suitable temperature conditions.

[0146] Step S1403, adjust the CDU unit operating number and the water pump operating frequency according to the deviation of the actual operating pressure difference from the setting value. As an example, the actual operating pressure difference of the main ring pipe terminal is collected in real time, and the CDU unit operating number and the water pump operating frequency are adjusted according to the deviation of the actual operating pressure difference from the main ring pipe terminal pressure difference setting value △P0, to ensure that the operating condition point is at the system high efficiency point.

[0147] Step S1404, collect and store the server key component operating temperature [t] and the server cabinet power consumption [p] in real time.

[0148] Step S1405, calculate the system power consumption P according to the power consumption model.

As an example, t min and t max are the minimum and maximum values of the preset temperature range, respectively, to determine whether the server key component temperature is within the preset temperature range.

As an example, F1 and F2 are the minimum and maximum values of the preset opening degree range, respectively, to determine whether the cabinet water supply pipe electric regulating valve opening degree is within the preset opening degree range.

[0152] Step S1409, if the result of step S1407 is "No", then adaptive energy saving optimization algorithm 2 is performed.

[0153] If the result of step S1407 is "Yes", then the process ends.

[0154] As an example, as shown in Figure 15 , Figure 14 Step S1408 can include steps S1501-S1507. Among them: step S1501, temperature distribution judgment: [t]≤t max . As an example, judge whether the second actual operating temperature t of the plurality of server key components is less than or equal to the maximum value of the preset temperature range.

[0155] Step S1502, if all temperatures in the second actual operating temperature t of the plurality of server key components are less than or equal to the maximum value t max of the preset temperature range, increase the cabinet return water temperature set value by the preset temperature increment, that is: T i+1 =T i +dT, i=1,2…

[0156] Step S1503, if any temperature t in the second actual operating temperature t of the plurality of server key components is greater than the maximum value t max of the preset temperature range, decrease the cabinet return water temperature set value by the preset temperature increment, that is: T i+1 =T i -dT, i=1,2…

[0157] Step S1504, run for a preset time (such as: run x hours), and collect and store the server key component operating temperature [t] and the server cabinet power consumption power [p] in real time.

[0158] Step S1505, temperature distribution judgment: t min ≤[t]≤t max . As an example, t min and t max are the minimum and maximum values of the preset temperature range, respectively, to judge whether the server key component temperature is within the preset temperature range.

[0159] Step S1506, if the result of step S1505 is "Yes", that is, the second actual operating temperature t is within the preset temperature range, then the adjusted cabinet return water temperature set value T0 is used as the newly set cabinet return water temperature set value T0, that is: T0=T i+1 .

[0160] If the result of the step S1505 is "No", return to step S1501.

[0161] Step S1507, output the optimal control T0.

[0162] As an example, as shown in Figure 16 , Figure 14 Step S1409 can include steps S1601-S1608.

[0163] Wherein:

[0164] Step S1601, adjust the valve opening judgment: F≤F1. As an example, determine whether the opening F of the electric regulating valve is less than or equal to the minimum value F1 of the preset opening range.

[0165] Step S1602, if the result of step S1601 is "Yes", then reduce the main loop end pressure difference set value △P0 by the preset pressure difference increment, that is: △P i+1 =△P i -d(△P), i=0,1…

[0166] Step S1603, if the result of step S1601 is "No", then increase the main loop end pressure difference set value △P0 by the preset pressure difference increment, that is: △P i+1 =△P i +d(△P), i=0,1…

[0167] Step S1604, run for a preset time (such as: x hours), and collect and store the server key component operating temperature [t] and server cabinet power consumption [p] in real time.

[0168] Step S1605, determine whether the server key component operating temperature t i,k is less than or equal to the preset temperature value, that is, determine whether t i,k ≤(t max -a2), k=0,1… As an example, t i,k is the operating temperature of the kth server key component of the ith server cabinet, t max is the maximum value of the preset temperature range, and a2 is the redundancy temperature value. The preset temperature value is equal to the maximum value t max of the preset temperature range minus the redundancy temperature value a2.

[0169] Step S1606, if the result of step S1605 is "Yes", adjust the valve opening judgment: F1≤F≤F2. As an example, F1 and F2 are the minimum and maximum values of the preset opening range, respectively.

[0170] If the step S1605 is the result of "No", return to step S1603.

[0171] Step S1607, if the step S1606 is the result of "Yes", with the adjusted main ring pipe end pressure difference set value △P0 as the re-set main ring pipe end pressure difference set value △P0, that is: △P 0＝ △P i+1 .

[0172] If the step S1606 is the result of "No", return to step S1601.

[0173] Step S1608, output the optimal control △P0.
