Description

Technical Field

[0001] The present application relates to the field of liquid cooling technology, and in particular to a two-phase cold plate cooling system, a cooling micromodule device and a data center. Background Art

[0002] Currently, the commonly used data center liquid cooling technologies mainly include immersion liquid cooling technology and cold plate liquid cooling technology.

[0003] Immersion liquid cooling technology is mainly based on immersion phase change liquid cooling technology. This technology is to immerse all IT equipment in coolant. The coolant absorbs the heat of heat-generating components such as chips, memory, and power supplies, and then heats up and vaporizes, taking away the heat of the heat-generating components in the form of phase change heat transfer. This technology mainly takes away the heat of the heat-generating components through the latent heat of the phase change of the cooling medium. It has high heat exchange efficiency and good cooling effect, but it needs to solve the compatibility problem between the cooling medium and electronic components.

[0004] Cold plate liquid cooling technology mostly uses single-phase cold plate technology, which is a non-contact liquid cooling technology. It uses liquid as a cooling medium to flow in the internal flow channel of the cold plate, and cools the heat source through heat transfer. It is widely used in electronic equipment, automobile engines, industrial equipment and other fields. The principle of this technology is to contact the heat source with the cold plate, transfer the heat of the electronic equipment to the cold plate, and then take the heat out of the cold plate through the cooling medium in the cooling medium pipeline to dissipate heat. Finally, the cooling medium is driven by the circulation system to continuously flow through the heat sink to maintain the stable operation of the liquid cooling system. This technology can effectively solve the problem of overheating of electronic equipment and improve the reliability and stability of the equipment. The cooling medium in the single-phase cold plate is a water-based solution. There are a series of water quality problems such as impurities, deionization, and mold that need to be solved, which increases the operation and maintenance cost of the system to a certain extent and reduces the reliability of the system operation. In addition, due to the conductivity of the water-based solution, once it leaks, it will cause damage to the components of the server, which has certain safety hazards.

[0005] Phase change cold plate cooling technology is an organic combination of the electronic fluorinated liquid used in immersion phase change technology and cold plate technology. Driven by the circulation system, the cooling medium of the two-phase cold plate cooling system enters the cold plate in liquid form. After absorbing the heat of the cold plate, part of the cooling medium vaporizes to form a vapor-liquid two-phase state and flows out of the cold plate. The vapor-liquid two-phase cooling medium flowing out of the cold plate passes through the secondary cooling system and turns back into liquid phase, and finally re-enters the cold plate driven by the circulation pump. In addition, the two-phase cold plate has higher heat exchange efficiency and lower cooling medium flow rate than the single-phase cold plate, so it can better meet the heat dissipation needs of high heat flux density.

[0006] Compared with the traditional single-phase cold plate cooling technology, the phase change cold plate cooling system uses a fluorinated cooling medium with a lower boiling point, which effectively solves a series of water quality problems existing in water-based solutions. At the same time, since the fluorinated cooling medium has the advantages of high insulation, no ignition point, and no flash point, it will not cause damage to server components after leakage, and has high safety.

[0007] Conventional two-phase cold plate cooling systems still have some problems in terms of structural design and implementation:

[0008] 1. Uneven liquid supply to cold plates. Due to the different loads of each branch, different required flow and pressure, multiple cold plate branches share a main circulation system, and the distribution of cooling medium flow in each branch is uncontrollable, resulting in uneven cooling effect between different cold plates. In order to ensure that each branch cold plate has sufficient flow of medium, the power of the main circulation loop pump can only be increased, resulting in energy consumption and reduced system efficiency.

[0009] 2. The recovery problem of the gas-liquid two-phase cooling medium output by the two-phase cold plate. After the gas-liquid two-phase cooling medium enters the manifold, part of the gas phase medium cannot be effectively separated in time, and part of the medium will be discharged with the system exhaust, resulting in medium loss. Summary of the invention

[0010] Based on this, it is necessary to provide a two-phase cold plate cooling system, cooling micro-module device and data center to address the problems of complex water quality and leakage safety hazards of single-phase cold plates, uncontrollable flow of two-phase cold plate branches, and incomplete gas-liquid separation.

[0074] The present application provides a two-phase cold plate cooling system, as shown in FIGS. 1 to 10 , the two-phase cold plate cooling system comprises:

[0075] A plurality of two-phase cold plates 110, used for heat transfer connection with the part to be cooled 900;

[0076] The electric-liquid integrated distribution module is connected to the two-phase cold plate 110 and the part to be cooled 900 respectively; it is used to collect the power consumption information corresponding to the part to be cooled 900 at each node; and control the flow rate of the fluid in the two-phase cold plate 110 according to the power consumption information;

[0077] The fluid separation module is connected to the electric-liquid integrated distribution module and the liquid cooling heat exchange module 200 respectively; the fluid separation module collects the gas-liquid mixed fluid from the electric-liquid integrated distribution module and separates the gas-liquid into gaseous fluid and liquid fluid; the gaseous fluid and the liquid fluid are connected to the liquid cooling heat exchange module 200 through different pipelines respectively;

[0078] The liquid-cooled heat exchange module 200 is respectively connected to the electro-liquid integrated distribution module and / or the fluid separation module. The liquid-cooled heat exchange module 200 receives vapor fluid and liquid fluid through different pipelines and cools the cooled fluid to a preset temperature, and supplies the cooled fluid to the two-phase cold plate 110 through the electro-liquid integrated distribution module.

[0079] In the above two-phase cold plate cooling system, when the part to be cooled 900 generates a large amount of heat, the heat is first transferred to the cooling fluid in the two-phase cold plate 110. After the fluid absorbs the heat, it quickly evaporates and becomes a vapor fluid. The latent heat of evaporation of the cooling fluid is used to quickly take away the heat from the part to be cooled 900, so that the part to be cooled 900 can be kept at the optimal temperature for a long time and operate stably, reducing the hot spot phenomenon and greatly extending the service life of the part to be cooled 900. This application is to further solve the problem that the different heat generation of each part to be cooled 900 makes it easy for part of the two-phase cold plate 110 to dry burn, and no phase change occurs in the two-phase cold plate 110. In serious cases, it will cause abnormal temperature rise inside the system and excessive system energy consumption.

[0080] Secondly, the present application also provides an electro-hydraulic integrated distribution module, and the electro-hydraulic integrated distribution module is respectively connected to the two-phase cold plate 110 and the part to be cooled 900. The electro-hydraulic integrated distribution module can collect the power consumption information corresponding to the part to be cooled 900 at each node; and control the flow rate of the fluid in the two-phase cold plate 110 according to the power consumption information, thereby adjusting the liquid inlet amount of the two-phase cold plate 110. Specifically, the electro-hydraulic integrated distribution module can calculate the heating value by collecting the power consumption information of the parts to be cooled 900 at each node, or calculate the heating value of the corresponding parts to be cooled 900 by collecting the cooling information of each two-phase cold plate 110 (for example, the flow rate of each liquid supply branch), or calculate the heating value of the corresponding parts to be cooled 900 based on the power consumption information and the cooling information at the same time, and then control the flow rate of each liquid supply branch of the two-phase cold plate 110 based on the heating value, so that the liquid fluid enters the two-phase cold plate 110 to absorb heat and immediately undergoes phase change and vaporizes to become a vapor fluid; the phase change heat transfer potential of the two-phase cold plate 110 at each node can be maximized, the system heat exchange efficiency can be improved, and the energy consumption of the data center can be reduced.

[0081] Furthermore, the present application also sets a fluid separation module, which collects the gas-liquid mixed fluid from the electric-liquid integrated distribution module for gas-liquid separation, thereby separating it into gaseous fluid and liquid fluid; and connects the separated gaseous fluid and liquid fluid to the liquid cooling heat exchange module 200 through different pipelines. Specifically, the system can quickly separate the gas-liquid mixed fluid of the two-phase cold plate 110, which not only enhances the heat exchange efficiency of the liquid cooling heat exchange module 200, but also further improves the stability of the system operation; effectively reduces the loss of cooling fluid.

[0082] Furthermore, the electro-hydraulic integrated distribution module is connected to a plurality of node two-phase cold plates 110 in parallel through pipelines; wherein, each node two-phase cold plate 110 may be provided with a plurality of two-phase cold plates arranged in series or a plurality of two-phase cold plates arranged in parallel.

[0084] Furthermore, the electro-hydraulic integrated distribution module and the fluid separation module are provided as an integrated structure; or, the electro-hydraulic integrated distribution module and the fluid separation module are provided as separate bodies.

[0091] When the electric-liquid integrated distribution module and the fluid separation module are set as an integrated structure, the electric-liquid integrated distribution module of this embodiment not only sets the first cooling capacity distribution unit 400, but also the fluid cooled by the liquid-cooled heat exchange module 200 flows into the two-phase cold plate 110 of each node through the first distribution pipeline body 410, each branch of the first distribution pipeline body 410 and the cooling capacity self-regulating component. By setting the second cooling capacity distribution unit 500, the fluid separation module is set in the second distribution pipeline body, and the gas-liquid mixed fluid flowing out of the two-phase cold plate 110 of each node flows into the second distribution pipeline body, and the gas-liquid mixed fluid is separated by the fluid separation module, and the separated gaseous fluid and liquid fluid flow into the liquid-cooled heat exchange module 200. The power distribution unit 300 is also electrically connected to the parts to be cooled 900 at each node through the power distribution trunk line 310, so as to collect the power consumption information corresponding to the parts to be cooled 900 at each node and / or the cooling capacity information of the two-phase cold plate 110 at each node, and transmit the power consumption information and / or the cooling capacity information to the control unit 600; the control unit 600 adjusts the working frequency of the cooling capacity self-regulating component corresponding to each node according to the power consumption information and / or the output power information, thereby adjusting the liquid inlet of the two-phase cold plate 110 at each node.

[0107] It is understandable that the specific number of liquid cooling heat exchange modules 200 is set according to actual operation requirements.

[0108] Embodiment 2

[0109] As shown in FIG. 7 to FIG. 10 , when the electro-hydraulic integrated distribution module and the fluid separation module are separately arranged, the fluid separation module is arranged on the upper side of the electro-hydraulic integrated distribution module;

[0110] Preferably, the two-phase cold plate cooling system comprises a plurality of liquid cooling cabinets 100 , each of which comprises a plurality of two-phase cold plates 110 ;

[0111] The fluid separation module includes an electric-liquid integrated distribution module disposed on the upper side of the liquid cooling cabinet 100 and connected to at least two corresponding liquid cooling cabinets 100, forming a gas-liquid separation and cooling transport ring network 800;

[0112] More preferably, the gas-liquid separation and cooling transport ring network 800 is connected to each liquid cooling cabinet 100 through corresponding pipelines to form a fluid circulation, and the gas-liquid two-phase mixed fluid of each liquid cooling cabinet 100 flows into the gas-liquid separation and cooling transport ring network 800 through the pipeline for gas-liquid separation, and the separated liquid phase fluid flows into the two-phase cold plate 110 through the pipeline and the electric-liquid integrated distribution module in turn; the separated gas phase fluid flows into the liquid cooling heat exchange module 200.

[0113] In the two-phase cold plate cooling system of this embodiment, the gas-liquid mixed fluid discharged from the two-phase cold plate 110 at each node flows into the fluid separation module. Because the fluid separation module is arranged on the upper side of the electric-liquid integrated distribution module, the gas-liquid mixed fluid is buffered in the fluid separation module, and then the liquid fluid in the fluid separation module can continue to flow out to the two-phase cold plate 110 and continue to participate in the cold plate cooling; the gaseous fluid is liquefied in the fluid separation module, and part of it enters the liquid cooling heat exchange module 200. After being fully liquefied, it is continuously sent back to the fluid separation module to continue to participate in cooling, so that the gas-liquid mixed fluid can be further separated into gas and liquid, which not only enhances the heat exchange efficiency of the liquid cooling heat exchange module 200 and improves the stability of the system operation; and effectively reduces the loss of cooling fluid. It can also make the system operate under a stable system pressure, and supply the liquid fluid of the preset temperature obtained after separation to the electric-liquid integrated distribution module (wherein the preset temperature includes but is not limited to the fluid saturation temperature, slightly lower than the fluid saturation temperature) through the gas-liquid separation and cold delivery ring network 800, so as to improve the phase change heat exchange efficiency of the two-phase cold plate 110 at each node. Once the liquid fluid flows through the two-phase cold plate 110 and exchanges heat with the cooling element 900, it can undergo phase change and vaporization, maximizing the use of the phase change latent heat of the fluid and improving the phase change heat transfer efficiency of the two-phase cold plate 110 at each node. Experimental comparison shows that the heat dissipation effect of the liquid cooling cabinet of the present application can be increased by more than double, which can effectively increase the installation density of the liquid cooling cabinet 100 in the two-phase cold plate system and reduce the power distribution power of the data center computer room; it can also directly achieve zero-carbon heating.

[0114] In one embodiment, the vapor-liquid separation and cooling transport ring network 800 includes a main liquid inlet pipeline connected to each liquid cooling cabinet 100, a main steam outlet pipeline connected to each liquid cooling cabinet 100, and a control component arranged on the main liquid inlet pipeline and / or the main steam outlet pipeline.

In addition, control components are provided on the main liquid inlet pipeline and the main steam outlet pipeline to control the opening and closing of the main liquid inlet pipeline and the main steam outlet pipeline.

[0116] Preferably, the main liquid inlet pipeline and the main steam outlet pipeline can be integrally arranged and installed on the upper side of the liquid cooling cabinet 100;

[0117] More preferably, the control component is a control valve 810 .

[0122] The control unit 600 is electrically connected to the power distribution unit and the cooling self-regulating component, respectively. The control unit 600 collects the power consumption information corresponding to the cooling parts 900 of each node through the power distribution unit; and / or the output power information of each power distribution trunk line 310 in the power distribution unit; and adjusts the working frequency of the cooling self-regulating component corresponding to each node according to the power consumption information and / or the output power information.

By providing a third cooling capacity distribution unit, the gas-liquid mixed fluid flowing out of the two-phase cold plate 110 of each node flows into the gas-liquid separation and cooling capacity delivery ring network 800 in sequence through the third fluid pipeline and the third pipeline body, and is buffered and separated in the gas-liquid separation and cooling capacity delivery ring network 800, and the separated gaseous fluid and liquid fluid flow into the liquid-cooled heat exchange module 200. The power distribution unit 300 is electrically connected to the components to be cooled 900 at each node through the power distribution trunk line 310, so as to collect the power consumption information corresponding to the components to be cooled 900 at each node and / or the cooling capacity information of the two-phase cold plate 110 at each node, and transmit the power consumption information and / or the cooling capacity information to the control unit 600; the control unit 600 adjusts the operating frequency of the cooling capacity self-regulating component corresponding to each node according to the power consumption information and / or the output power information, thereby adjusting the liquid inlet amount of the two-phase cold plate 110 at each node.

Alternatively, the fluid cooled by the liquid cooling heat exchange module 200 can flow into the two-phase cold plate 110 of each node through the first distribution pipeline body 410, the second liquid distribution branch 430 and the second cooling capacity self-regulating part of the cooling capacity self-regulating component.

[0128] It should be noted that the first cooling distribution unit 400 provides two flow paths, and the fluid cooled by the liquid-cooled heat exchange module 200 can select one of the flow paths, and the other flow path can be used as a backup.

[0129] Specifically, the first and second cooling capacity self-regulating parts include a cooling capacity self-regulating pump 440 and / or a cooling capacity self-regulating valve 450. The first cooling capacity self-regulating part and the second cooling capacity self-regulating part both include a cooling capacity self-regulating pump 440 and / or a cooling capacity self-regulating valve 450, that is, the cooling capacity self-regulating pump 440 and / or the cooling capacity self-regulating valve 450 are provided on the first liquid separation branch 420 and the second liquid separation branch 430.

[0130] More specifically, the cooling capacity self-regulating valve 450 is a one-way valve, which is used to limit the flow direction of the liquid cooling medium in the first liquid distribution branch 420 or the second liquid distribution branch 430 so that it can only flow from the cooling capacity self-regulating pump 440 to the corresponding two-phase cold plate 110.

[0131] Furthermore, in order to improve the liquid separation efficiency, as shown in FIGS. 8 to 10 , at least one liquid-cooled heat exchange module 200 is provided, and at least one liquid-cooled heat exchange module 200 is connected to the gas-liquid separation and cold transport ring network 800 .

[0132] In a specific embodiment, as shown in Figure 8, multiple groups of liquid cooling cabinets 100, a vapor-liquid separation and cold transport ring network 800 and a liquid cooling heat exchange module 200 are provided. A vapor-liquid separation and cold transport ring network 800 is connected to a liquid cooling heat exchange module 200 through a pipeline, and multiple groups of liquid cooling cabinets 100 are all connected to a vapor-liquid separation and cold transport ring network 800 through a pipeline circulation.

[0135] It is understandable that the specific number of liquid cooling heat exchange modules 200 is set according to actual operation requirements.

[0136] In summary, the working principle adopted in the first embodiment of the present application (as shown in FIGS. 3 to 6 ) is as follows:

[0137] Primary liquid supply process: The low-temperature refrigerant is pressurized by the power equipment in the liquid cooling heat exchange module 200 and transported to the first cooling capacity distribution unit 400 through pipelines;

[0138] Secondary liquid supply process: The liquid fluid in the first distribution pipeline body 410 of the first cooling distribution unit 400 is extracted by the cooling self-regulating pump 440 and transported to the two-phase cold plate 110 of each node to cool the component to be cooled 900 (IT equipment). Heat is transferred to the component to be cooled 900 through the two-phase cold plate 110, and the liquid cooling medium in the two-phase cold plate 110 is heated and evaporated.

[0139] Primary liquid (gas) return process: The heated cooling medium in the two-phase cold plate 110 enters the second cooling distribution unit 500 in the form of a gas-liquid two-phase flow. Under the action of gravity, the gas-liquid mixed fluid is separated by the fluid separation module in the second distribution pipeline body of the second cooling distribution unit 500. The separated gaseous fluid flows upward and flows out through one of the fluid outlets, and the liquid fluid flows downward and flows out through the other fluid outlet.

[0140] Secondary air return process: the gaseous fluid flowing out through one of the fluid outlets finally enters the liquid-cooled heat exchange module 200 through the pipeline for cooling under the action of the condensation pressure difference of the liquid-cooled heat exchange module 200. The cooled cooling medium re-participates in the primary liquid supply, passes through the first liquid supply network 720, and is replenished into the first cooling capacity distribution unit 400.

[0141] Secondary liquid return process: the liquid fluid flowing out through another fluid outlet finally enters the liquid cooling heat exchange module 200 through the pipeline under the action of gravity for cooling, and the cooled cooling medium re-participates in the primary liquid supply.

[0142] The working principle adopted in the second embodiment of the present application (as shown in Figures 7 to 10) is as follows:

[0143] Primary liquid supply process: The low-temperature liquid phase cooling medium is pressurized by the power equipment in the liquid-cooled heat exchange module 200, and is transported through pipelines into the vapor-liquid separation and cold transport ring network 800. The liquid level of the vapor-liquid separation and cold transport ring network 800 is maintained stable by adjusting the valves on the pipelines connecting the vapor-liquid separation and cold transport ring network 800 and the liquid-cooled heat exchange module 200.

[0144] Secondary liquid supply process: vapor-liquid separation and cold transport The cooling medium in the ring network 800 is extracted by the cold self-regulating pump 440 of the cold distribution unit and transported to the two-phase cold plate 110. The cooling component 900 (IT equipment) dissipates heat to the cooling medium through the two-phase cold plate 110, and the cooling medium is heated and evaporates and gasifies.

[0145] Primary liquid (gas) return process: The cooling medium heated in the two-phase cold plate 110 returns to the gas-liquid separation and cold transport ring network 800 through pipelines in the form of gas-liquid two-phase flow.

[0146] Secondary return air flow: The two-phase cooling medium in the vapor-liquid separation and cold transport ring network 800 is separated under the action of gravity, wherein the gaseous cooling medium in the vapor-liquid separation and cold transport ring network 800 finally enters the liquid cooling heat exchange module 200 through the pipeline for cooling, and the cooled cooling medium re-participates in the primary liquid supply and is replenished into the vapor-liquid separation and cold transport ring network 800. The liquid cooling medium in the vapor-liquid separation and cold transport ring network 800 re-participates in the secondary liquid supply and is extracted by the cold self-regulating pump 440.

[0147] The beneficial effects of this application include:

[0148] (1) This application utilizes two-phase cooling technology and adopts fluorinated liquid with a lower boiling point as the cooling medium, which effectively solves a series of water quality problems such as water-based solution impurities, deionization, mold, etc. existing in traditional single-phase cold plates, and reduces the operation and maintenance costs of the system;

[0149] (2) The electronic fluorinated liquid used in this application has the advantages of high insulation, no ignition point, no flash point, etc., and will not cause damage to server components after leakage, thereby improving the reliability of system operation;

[0150] (3) The present application designs a cooling capacity self-regulating pump 440 on the cold plate branch of each cabinet, which can independently adjust the cooling medium flow and flow rate of the cold plate branch according to the heat generation and temperature rise of each cold plate, so as to realize independent liquid supply for each branch, and solve the problems of uncontrollable flow distribution of each branch of the conventional two-phase cold plate 110, uneven cooling effect between different cold plates, and poor stability of the circulation system. At the same time, the number of pumps for each cold plate branch is two (one for use and one for backup), and the cooling capacity self-regulating valve 450 is set on both the first liquid distribution branch 420 and the second liquid distribution branch 430. The cooling capacity self-regulating valve 450 is a one-way valve to ensure that the cooling medium will not flow back between the cooling capacity self-regulating pumps 440, thereby reducing the redundancy of the cooling system and improving the reliability of the system.

[0151] (4) In the present application (as shown in FIGS. 3 to 6 ), the two-phase cooling medium flows out from the two-phase cold plate 110, and the gaseous fluid flows upward along the pipeline through one of the fluid outlets of the second cooling distribution unit 500 and returns to the liquid-cooled heat exchange module 200, and then participates in the circulation again after being fully liquefied by the liquid-cooled heat exchange module 200. Under the action of gravity, the liquid fluid flows to the bottom through another fluid outlet of the second cooling distribution unit 500 and returns to the liquid-cooled heat exchange module 200 along the pipeline.

[0152] (5) The present application (as shown in FIGS. 7 to 10 ) designs a gas-liquid separation and cooling transport ring network 800 at the upper part of the main loop of the circulation system. The gas-liquid mixed fluid output by the two-phase cold plates 110 of each branch is converged to the gas-liquid separation and cooling transport ring network 800 through the pipeline, and then buffered in the gas-liquid separation and cooling transport ring network 800. The liquid fluid flows out from the bottom of the gas-liquid separation and cooling transport ring network 800 to continue to participate in the cooling of the cold plate; the gaseous fluid is liquefied in the gas-liquid separation and cooling transport ring network 800, and part of it enters the liquid cooling heat exchange module 200 (CDM). After being fully liquefied, it is sent back to the gas-liquid separation and cooling transport ring network 800 to continue to participate in the cooling.

[0153] (6) In order to ensure the reliability of centralized liquid supply to multiple cabinets, the present application (as shown in FIGS. 3 to 6 ) uses a common gas-liquid separation and cooling capacity delivery ring network 800 for multiple liquid cooling cabinets 100, thereby realizing a compact arrangement of the system structure. At the same time, according to the number of liquid cooling cabinets 100, multiple liquid cooling heat exchange modules 200 are provided, which can ensure that multiple liquid cooling heat exchange modules 200 participate in the liquefaction and supply of the cooling medium together, and can also realize the mutual master-slave relationship between the liquid cooling heat exchange modules 200, thereby ensuring the reliability of the cooling medium liquid supply.

[0154] Furthermore, in order to finely adjust the liquid inlet amount of each two-phase cold plate 110 of the liquid cooling cabinet 100, in some embodiments, the two-phase cold plate cooling system further includes a first flow meter electrically connected to the control unit 600, the first flow meter is installed on the first liquid distribution branch 420 and / or the second liquid distribution branch 430 on the pipeline area connecting the cold capacity self-regulating pump 440 and the two-phase cold plate 110, and the first flow meter is used to detect the liquid inlet flow of the two-phase cold plate 110 and transmit the data to the control unit 600. By setting the first flow meter to detect the actual liquid inlet flow of the two-phase cold plate 110, the control unit 600 can correct the operating frequency of the cold capacity self-regulating pump 440 according to the actual liquid inlet flow.

[0155] Specifically, a plurality of first flow meters are provided, and the plurality of first flow meters are provided one-to-one on the plurality of first liquid separation branches 420 and / or the second liquid separation branches 430 , so as to detect the actual liquid inlet flow of each two-phase cold plate 110 .

[0156] Specifically, the control unit 600 is provided with a preset flow value, and the control unit 600 compares the actual liquid inlet flow rate with the preset flow value. If the preset flow value is greater than the actual liquid inlet flow rate, it is determined that the actual liquid inlet flow rate is small and does not meet the demand. At this time, the control unit 600 increases the operating frequency of the cold capacity self-regulating pump 440, and increases the liquid inlet amount of the two-phase cold plate 110. If the preset flow value is less than the actual liquid inlet flow rate, it is determined that the actual liquid inlet flow rate is large and exceeds the demand. At this time, the control unit 600 reduces the operating frequency of the cold capacity self-regulating pump 440 and reduces the liquid inlet amount of the two-phase cold plate 110.

[0157] In some embodiments, the two-phase cold plate cooling system further includes a second flow meter electrically connected to the control unit 600, the flow meter is installed on the main steam outlet pipeline, and the second flow meter is used to detect the discharge flow of the two-phase cold plate 110 and transmit the data to the control unit 600. By setting the second flow meter to detect the actual discharge flow of the two-phase cold plate 110, the control unit 600 can correct the operating frequency of the cooling capacity self-regulating pump 440 according to the actual discharge flow.

[0158] Specifically, a plurality of second flow meters are provided, and the plurality of second flow meters are provided one-to-one on a plurality of main steam outlet pipelines, so as to detect the actual discharge flow of each two-phase cold plate 110 of the cooling system.

[0159] Embodiment 3

[0160] The present application also provides a control method for a two-phase cold plate cooling system, the control method for a two-phase cold plate cooling system comprising:

[0161] The control unit 600 is electrically connected to the cooling capacity self-regulating pump 440 and the power distribution trunk 310 of the power distribution unit respectively;

[0162] The power distribution trunk 310 is used to be electrically connected to the component to be cooled 900, and the power distribution trunk 310 is used to transmit the power consumption information of the component to be cooled 900 to the control unit 600;

[0163] The control unit 600 calculates the power of the two-phase cold plate 110 of the cold capacity distribution unit according to the power consumption information transmitted by the power distribution trunk line 310, and controls the working frequency of the cold capacity self-regulating pump 440 according to the power.

[0164] The control method of the above-mentioned cooling system electrically connects the control unit 600 to the self-regulating cold pump 440 of the cold distribution unit and the power distribution trunk 310 of the power distribution unit respectively, and electrically connects the power distribution trunk 310 to the part to be cooled 900. The power distribution trunk 310 can transmit the power consumption information of the part to be cooled 900 to the control unit 600. The control unit 600 determines the power of the two-phase cold plate 110 according to the power consumption information of the part to be cooled 900, and then controls the working frequency of the self-regulating cold pump 440 corresponding to the two-phase cold plate 110, and then adjusts the liquid inlet amount of the two-phase cold plate 110, thereby adjusting the cooling effect of the two-phase cold plate 110.

[0165] In some embodiments, as shown in FIGS. 9 and 10 , the control unit 600 calculates a correction coefficient according to a correction formula to correct the operating frequency of the cooling capacity self-regulating pump 440 ; the correction formula is: K=P / P 总, where K is the correction coefficient, P is the power of a single-layer two-phase cold plate 110, and Ptotal is the total power of multiple two-phase cold plates 110 in the cooling system. By using the correction formula to calculate the correction coefficient K, when the control unit 600 determines the power of the two-phase cold plate 110 according to the power consumption information of the component to be cooled 900, and then controls the working frequency of the cold capacity self-regulating pump 440 corresponding to each two-phase cold plate 110, the correction coefficient K is used to correct the working frequency of the cold capacity self-regulating pump 440520, thereby improving the adjustment precision and accuracy.

[0166] Specifically, as shown in FIGS. 9 and 10 , the control unit 600 calculates a correction coefficient according to a correction formula to correct the operating frequency of the cooling capacity self-regulating pump 440; the correction formula is: K=K H *P / P 总 , where K is the correction coefficient, P is the power of the single-layer two-phase cold plate 110, and P 总 is the total power of the multiple two-phase cold plates 110 of the cooling system, K H is the weight coefficient, which is defined according to the relative position between the two-phase cold plate 110 of each layer and the water inlet of the main liquid inlet pipeline. Considering the height difference of the two-phase cold plates 110 of the cooling system, the weight coefficient KH is derived. The weight coefficient KH is defined by the distance between the two-phase cold plates 110 of the corresponding number of layers and the water inlet of the main liquid inlet pipeline. The correction formula is K=K H *P / P 总 , further improving the correction accuracy.

[0167] More specifically, the weight coefficient K H It is positively correlated with the level of the two-phase cold plate 110. For example, when the distance H between some two-phase cold plates 110 and the water inlet of the main liquid inlet pipeline in the multi-layer two-phase cold plate 110 is within the range of H1, the weight coefficient KH is 1.1, and the distance H between some two-phase cold plates 110 and the water inlet of the main liquid inlet pipeline in the multi-layer double-break cold plate is greater than H1 and less than H2, the weight coefficient K H is 1.3, the distance H between some two-phase cold plates 110 in the multi-layer double-break cold plate and the water inlet of the main liquid inlet pipeline is greater than H3, and the weight coefficient K H is 1.5.

[0168] It should be noted that P in the correction formula refers to the power of a single-layer two-phase cold plate 110, and the liquid cooling cabinet 100 of the cooling system includes multiple layers of two-phase cold plates 110 arranged at intervals. Each layer of two-phase cold plate 110 corresponds to a correction coefficient. When it is necessary to correct the operating frequency of the corresponding level of the cold capacity self-regulating pump 440, the control unit 600 needs to calculate the correction coefficient of the corresponding level.

[0169] The present application also provides a cooling micromodule device, including the above-mentioned two-phase cold plate cooling system. The cooling micromodule device includes the above-mentioned cooling system, and the cooling micromodule device enhances the efficiency of two-phase cooling medium diversion through a fluid separation module, effectively separates the two-phase cooling medium, reduces the probability that part of the gas phase medium will be discharged with the system exhaust, and reduces the loss of cooling medium.

[0170] The present application also provides a data center, including the above two-phase cold plate cooling system. The data center uses a fluid separation module to divert the gas-liquid mixed fluid flowing out of the two-phase cold plate 110, reducing the probability that part of the gas phase medium will be discharged with the system exhaust, thereby reducing the loss of cooling medium.

[0171] The technical features of the above embodiments may be combined arbitrarily.
