[0002] As the core infrastructure of modern information technology, data centers carry a large number of servers and computer equipment operation tasks. During their operation, servers and other equipment continue to generate a lot of heat. If they cannot be effectively processed and cooled, it will cause equipment performance to decline or even fail, seriously affecting the stable operation of the data center. Traditional air-conditioning refrigeration methods are widely used in data centers. However, the computing load of data centers shows obvious peak-to-valley fluctuation characteristics. During the peak computing load period, the heat generated by the equipment increases sharply, and the air-conditioning system needs to operate at full capacity to maintain a low temperature environment; when the load is low, the cooling demand is greatly reduced. This dynamic change poses a huge challenge to traditional air-conditioning refrigeration. Since its cooling capacity is difficult to accurately match real-time demand, it often maintains a high power operation throughout the entire operation cycle, which consumes a lot of electricity resources and leads to high energy consumption. Existing technologies still need to be improved and enhanced. Summary of the invention

[0044] It should be further understood that the term “and / or” used in the present specification and the appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0045] Data centers carry a large number of devices, and servers and other equipment continue to generate heat. Poor heat dissipation will cause equipment performance damage and unstable operation. Traditional air conditioning and refrigeration are widely used in data centers, but the computing load in this field fluctuates significantly, with equipment heating up sharply during peak hours and cooling demand dropping sharply during low hours. Traditional air conditioners are difficult to accurately match cooling capacity to real-time demand, and often operate at high power throughout the entire operation cycle, consuming a lot of electricity and high energy consumption, which urgently needs to be improved.

[0046] The emergence of phase change materials provides a new idea for solving this problem. Phase change materials have the characteristics of being able to absorb or release a large amount of latent heat and undergo phase change at a specific temperature. In a data center, when the computing load reaches its peak, the heat generated by the equipment can be absorbed and stored by the phase change material, causing it to undergo a phase change; and when the computing load is at a valley value, the phase change material can release the stored heat. In this way, phase change materials can effectively adjust the heat distribution inside the data center, reduce peaks and fill valleys, and reduce the frequent high-load operation of traditional refrigeration systems when dealing with load fluctuations, thereby reducing overall refrigeration energy consumption. It can be seen that although phase change materials have significant advantages in theory, in actual data center application scenarios, how to reasonably layout phase change materials inside the data center, determine their optimal dosage, packaging form, and collaborative working mode with traditional refrigeration systems, etc.

[0047] Therefore, in order to solve the problems of the prior art, the present invention provides a data center thermal management method, which optimizes the power consumption of the data center by setting phase change materials in the data center and regulating the refrigeration equipment based on the phase change degree of the phase change materials, and solves the temperature changes in the data center caused by the peaks and valleys of computing loads, thereby causing excessive energy consumption of refrigeration equipment and low energy utilization efficiency.

[0048] This embodiment provides a data center thermal management method, which is applied to a data center equipped with refrigeration equipment and a thermal storage container. The thermal storage container is a sealed structure, and solid-liquid phase change material and gas are arranged in the thermal storage container.

[0049] The heat storage container structure and filler are the core of the present invention. In this embodiment, the heat storage container can be selected as a cubic shape. Preferably, it can be a flat rectangular parallelepiped structure, that is, its height dimension is significantly smaller than the length and width dimensions, and the length and width dimensions can be close to the length and width dimensions of the cabinet. Under this structure, the surface of the heat storage container can be closely fitted with the side wall of the cabinet, the contact area between the two is maximized, the heat conduction path is greatly shortened, and the heat can be transferred from the cabinet to the heat storage container at a faster speed, significantly improving the efficiency of heat exchange. Further, because the heat storage container is a sealed structure, it is necessary to reduce the deformation of the outer shell of the heat storage container due to the phase change state of the phase change material. Therefore, the outer shell of the heat storage container generally selects a high-strength metal material with good conductivity. Preferably, an aluminum alloy, stainless steel or copper alloy shell can be selected. In the heat storage container, a solid-liquid phase change material and a gas are provided. Among them, when the selected solid-liquid phase change material is easy to react chemically with the gas, the gas can choose to use a stable inert gas, but the pressure change of the inert gas will be smaller than that of the gas, and it is difficult to accurately monitor. Preferably, nitrogen can be used as the gas in the thermal storage container. Without the influence of water molecules and other trace gases in the gas, the phase change process of the solid-liquid phase change material is smoother and more stable. If economic benefits are considered, air can also be used as the gas in the thermal storage container. The selection of gas needs to be targeted according to the specific solid-liquid phase change material. Furthermore, the thermal storage container needs to be filled with enough solid-liquid phase change material. If the solid-liquid phase change material is too little, the total amount of heat energy that can be stored and released will be too little. Moreover, there needs to be enough gas in the thermal storage container to monitor the change of air pressure. If the gas is too little, the change in air pressure of the gas caused by the phase change of the phase change material will be difficult to be quantitatively monitored. Therefore, the solid-liquid phase change material in the thermal storage container needs to occupy at least 50% of the volume, and the gas volume accounts for at least 10%. Preferably, the solid-liquid phase change material in the thermal storage container occupies 80% of the volume, and the gas occupies 20% of the volume. Under this ratio, the thermal storage container has enough solid-liquid phase change material for storing and releasing heat energy, and there is enough gas for monitoring the change of air pressure.

[0050] The data center thermal management method, such as Figure 1 As shown, the specific steps include:

[0051] Step S100: acquiring a phase change state of a solid-liquid phase change material in the thermal storage container, and determining a minimum gas pressure and a maximum gas pressure of the gas in the thermal storage container based on the phase change state.

[0052] In one implementation, the data center thermal management method further includes the following preparatory steps before the thermal management method steps are implemented:

[0053] Step S010: Before obtaining the phase change state of the solid-liquid phase change material in the thermal storage container, obtain the optimal operating temperature of the data center.

[0054] In this embodiment, the optimal temperature for the operation of the data center refers to the average room temperature of the data center, that is, the average temperature of the environment near the cabinet, which is at a temperature suitable for the operation of the equipment in the data center. The average temperature of the environment can be obtained by a temperature sensor arranged near the cabinet of the data center. The optimal temperature can put the equipment in the data center in a suitable environmental state, ensure its data processing speed and computing power output, while ensuring the life of the equipment and maintaining energy consumption balance. Preferably, the optimal temperature of a general data center can be selected as a specific temperature value between 18°C ​​and 27°C. It should be clear that in view of the differentiating factors such as the type of business actually carried by the data center, the characteristics of the equipment equipped, and the cooling strategy adopted, the above-mentioned optimal temperature is not fixed, and it is still necessary to make targeted settings and dynamic adjustments based on specific actual needs.

[0055] Step S020: Determine the solid-liquid phase change material based on the optimal temperature.

[0056] In this embodiment, based on the actually selected optimal temperature of the data center, a solid-liquid phase change material having a phase change temperature close to the optimal temperature is selected as the solid-liquid phase change material in the thermal storage container.

[0057] In one implementation, the gas is air, and determining the solid-liquid phase change material based on the optimal temperature includes the following steps:

[0058] Step S021, obtaining the phase transition temperature of paraffin under different raw material ratios;

[0059] Step S022, obtaining a raw material ratio of paraffin having a phase change temperature that is the same as the optimal temperature;

[0060] Step S023: using the paraffin with the raw material ratio as the solid-liquid phase change material.

[0061] Paraffin wax has multiple excellent properties, such as high phase change latent heat, suitable phase change temperature range, excellent chemical stability, no supercooling and precipitation, and has the advantages of high safety and low cost. In view of this, in this embodiment, paraffin wax is preferably used as the solid-liquid phase change material in the heat storage container. Considering that the data center needs to maintain a specific temperature environment for operation, in order to make the selected paraffin wax meet the thermal management requirements of the data center, the phase change temperature of the paraffin wax needs to be accurately controlled to make it consistent with the optimal temperature of the data center. As a hydrocarbon mixture, the phase change temperature of paraffin wax is significantly affected by the length of the carbon chain. By accurately controlling the length of the carbon chain, paraffin wax products with different phase change temperature characteristics can be obtained; then, paraffin waxes with a variety of different carbon chain lengths are mixed and formulated in a specific proportion, and after repeated testing and optimization, a paraffin wax mixture with a phase change temperature that accurately matches the optimal temperature of the data center is finally obtained. Preferably, based on the premise of the optimal temperature of the data center of 18°C ​​to 27°C, a paraffin mixture including hexadecane, heptadecane, and octadecane is selected. Among them, the melting point of hexadecane is about 18°C, the melting point of heptadecane is about 22°C, and the melting point of octadecane is about 28°C. Furthermore, in order to increase the thermal conductivity of paraffin wax, a small amount of high thermal conductivity materials, such as copper powder, aluminum powder and other metal powders, can be added to the paraffin wax. A small amount of high thermal conductivity materials has little effect on the phase change temperature of the paraffin wax mixture, but will greatly increase the thermal conductivity of the stone, so that the heat emitted by the cabinet is transferred to the phase change material faster.

[0062] In one implementation, the data center thermal management method further includes the following preparatory steps:

[0063] Step S030: before obtaining the phase change state of the solid-liquid phase change material in the thermal storage container, determining the position and quantity of the thermal storage container based on the heat distribution of the data center;

[0064] Step S040: deploying thermal storage containers in the data center based on the locations and quantities of the thermal storage containers.

[0065] In this embodiment, before obtaining the phase change state of the solid-liquid phase change material in the heat storage container, the location and number of the heat storage container are determined according to the heat distribution of the data center. Through temperature sensors and other equipment, the temperature of each area of ​​the data center is continuously monitored, and the cabinet area with higher temperature and the cabinet area with lower temperature are confirmed. Combined with the layout of the data center and the power parameters of the equipment, a temperature distribution model of the data center is constructed to plan the layout and number of the heat storage container. For the cabinet area with higher temperature, more heat storage containers should be densely arranged; for the edge area with low heat dissipation, the number of arrangements should be reduced accordingly. Among them, based on the shape structure of the heat storage container, the heat storage container is arranged with the side wall of the cabinet, and it fits closely with the side wall of the cabinet to increase the heat conduction efficiency. Furthermore, in addition to analyzing the heat distribution of the data center, it is necessary to further analyze the influence of the location of the cooling equipment of the data center on the layout position of the heat storage container, which is not expanded here. Based on the above-mentioned heat storage container layout scheme, the actual deployment of heat storage containers is carried out in the data center.

[0066] In one implementation, the obtaining of the phase change state of the solid-liquid phase change material in the thermal storage container and determining the minimum gas pressure and the maximum gas pressure of the gas in the thermal storage container based on the phase change state specifically include the following steps:

[0067] Step S110, based on the physical properties of the solid-liquid phase change material, obtaining the phase change state of the solid-liquid phase change material, the phase change state of the solid-liquid phase change material including a completely solid state, a phase change transition state, and a completely liquid state;

[0068] Step S120, when the phase change state of the solid-liquid phase change material is a completely solid state, obtaining the minimum air pressure of the heat storage container through the air pressure sensor in the heat storage container;

[0069] Step S130: When the phase change state of the solid-liquid phase change material is a completely liquid state, the maximum air pressure of the heat storage container is obtained through the air pressure sensor in the heat storage container.

[0070] In this embodiment, the heat storage container is further provided with an air pressure sensor for real-time monitoring of the air pressure of the gas in the heat storage container. Before the heat storage container is provided, a phase change test is first performed on the heat storage container. The heat storage container is placed in an environment with a temperature far lower than the phase change temperature of the solid-liquid phase change material in the heat storage container, and the solid-liquid phase change material is waited for to completely change into a solid state. The air pressure sensor reading at this time is continuously obtained, and the air pressure sensor reading gradually becomes stable. When the air pressure sensor reading does not change further, the reading is used as the minimum air pressure of the heat storage container. The minimum air pressure represents the air pressure of the gas when the solid-liquid phase change material in the heat storage container is completely solid. Similarly, the heat storage container is placed in an environment with a temperature far higher than the phase change temperature of the solid-liquid phase change material in the heat storage container, and the solid-liquid phase change material is waited for to completely change into a liquid state. The air pressure sensor reading at this time is continuously obtained, and the air pressure sensor reading gradually becomes stable. When the air pressure sensor reading does not change further, the reading is used as the maximum air pressure of the heat storage container. The maximum air pressure represents the air pressure of the gas when the solid-liquid phase change material in the heat storage container is completely liquid.

[0071] Step S200: obtaining the current air pressure in the thermal storage container, and determining the current phase change degree of the solid-liquid phase change material based on the current air pressure, the minimum air pressure, and the maximum air pressure.

[0072] In this embodiment, it is necessary to obtain the phase change degree of the solid-liquid phase change material in the thermal storage container in real time, and the phase change degree is used to reflect the dynamic change of heat in the environment where the thermal storage container is located. The phase change degree can be obtained by the relationship between the air pressure value monitored in real time by the air pressure sensor in the thermal storage container and the minimum air pressure and maximum air pressure of the gas in the thermal storage container.

[0073] In one implementation, the obtaining of the current air pressure in the thermal storage container and determining the current phase change degree of the solid-liquid phase change material based on the current air pressure, the minimum air pressure, and the maximum air pressure specifically includes the following steps:

[0074] Step S210, setting a numerical range corresponding to the phase change degree of the solid-liquid phase change material, wherein the numerical range reflects the value range corresponding to the phase change degree of the solid-liquid phase change material when the gas pressure in the thermal storage container changes from the minimum pressure to the maximum pressure;

[0075] Step S220: Determine the current phase change degree of the solid-liquid phase change material based on the current gas pressure and the numerical range.

[0076] In this embodiment, in order to facilitate the characterization of the phase change degree of the phase change material, a percentage value range is used to describe it. The percentage value range is from 0% to 100%. Among them, the phase change degree is 0%, which corresponds to the phase change state when the solid-liquid phase change material is completely solid. At this time, the gas pressure of the gas in the heat storage container is equal to the minimum gas pressure. Therefore, the minimum gas pressure is associated with 0%; the phase change degree is 100%, which corresponds to the phase change state when the solid-liquid phase change material is completely liquid. At this time, the gas pressure of the gas in the heat storage container is equal to the maximum gas pressure. Therefore, the maximum gas pressure is associated with 100%. In other words, when the solid-liquid phase change material in the heat storage container is in a phase change transition state, that is, a latent heat storage state, the phase change degree is greater than 0% and less than 100%. At this time, the gas pressure of the gas in the heat storage container is also greater than the minimum gas pressure and less than the maximum gas pressure. In general, there is a linear correlation between the degree of phase change and the air pressure, and the degree of phase change is characterized by a percentage value range of 0%-100%, which corresponds to the air pressure change range of the gas in the thermal storage container, from the minimum air pressure to the maximum air pressure. Therefore, by reading the air pressure sensor in the thermal storage container in real time, obtaining the current air pressure of the gas, and calculating the specific point where the current air pressure of the gas is in the range of the minimum air pressure and the maximum air pressure, the current phase change state of the solid-liquid phase change material in the thermal storage container can be obtained, that is, the specific phase change degree of the phase change material can be obtained.

[0077] Step S300: adjusting the cooling power of the cooling equipment in the data center based on the phase change degree.

[0078] In this embodiment, when the current phase change state of the solid-liquid phase change material in the thermal storage container is indirectly obtained through the reading of the air pressure sensor in the thermal storage container, the cooling power of the refrigeration equipment in the data center can be adjusted according to the phase change degree.

[0079] In one implementation, adjusting the cooling power of the cooling equipment in the data center based on the phase change degree specifically includes the following steps:

[0080] Step S310: when the phase change degree is higher than a preset threshold, increase the power consumption of the refrigeration equipment;

[0081] Step S320: When the phase change degree is lower than a preset threshold, the power consumption of the refrigeration equipment is reduced.

[0082] In this embodiment, an upper threshold and a lower threshold of the phase change degree are preset, and the upper threshold and the lower threshold are also percentage values. When the solid-liquid phase change material in the heat storage device reaches the upper threshold, it indicates that it has absorbed enough heat and is approaching a completely liquid state. At this time, the heat absorption capacity of the phase change material is difficult to maintain a suitable temperature, and the power consumption of the refrigeration equipment needs to be increased to reduce the total heat of the data center and ensure that the hardware operates stably in a safe temperature range. When the solid-liquid phase change material reaches the lower threshold, it means that it has released a large amount of heat and is close to a completely solid state. This situation shows that the data center is losing too much heat and the temperature is declining. If this continues, it will affect the performance of electronic equipment and increase energy consumption. Therefore, it is necessary to reduce the power consumption of the refrigeration equipment to maintain the total heat of the data center within a reasonable range to ensure stable and efficient operation of the system.

[0083] In summary, under the technical solution of the above embodiment, by setting phase change materials in the data center and regulating the refrigeration equipment based on the phase change degree of the phase change materials, the power consumption of the data center is optimized, and the temperature changes caused by the peaks and valleys of computing loads in the data center, resulting in excessive energy consumption of the refrigeration equipment and low energy utilization efficiency, are solved.
