[0049] The present application provides a cooling system, such as Figures 1 to 6 As shown, the cooling system comprises:

[0050] A plurality of phase change cold plates 110 are used to be in heat transfer connection with the to-be-cooled member 900;

[0051] An electro-hydraulic integrated distribution module is connected with the phase change cold plate 110 and the to-be-cooled member 900, respectively; used to collect the power consumption information corresponding to each node to-be-cooled member 900; and control the flow of the fluid in the phase change cold plate 110 according to the power consumption information;

[0052] a fluid separation module connected with the electro-hydraulic integrated distribution module and the liquid cooling heat exchange module 200 respectively; the fluid separation module separates the gas-liquid mixed fluid collected from the electro-hydraulic integrated distribution module into gaseous fluid and liquid fluid; the gaseous fluid and the liquid fluid are communicated with the liquid cooling heat exchange module 200 through different pipelines respectively;

[0053] the liquid cooling heat exchange module 200 is connected with the electro-hydraulic integrated distribution module and / or the fluid separation module, the liquid cooling heat exchange module 200 receives gaseous fluid and liquid fluid through different pipelines and cools them to cooled fluid at a preset temperature, and then supplies the cooled fluid to the phase change cold plate 110 through the electro-hydraulic integrated distribution module.

[0054] In the above cooling system, when the to-be-cooled component 900 generates a large amount of heat, the heat is first transferred to the cooling fluid in the phase change cold plate 110, the fluid absorbs heat and rapidly evaporates into gaseous fluid, the latent heat of evaporation of the cooling fluid rapidly removes the heat from the to-be-cooled component 900, so that the to-be-cooled component 900 can be kept at an optimal temperature for a long time, reducing the heat spot phenomenon and greatly prolonging the service life of the to-be-cooled component 900. In order to further solve the problem that the heat generated by each to-be-cooled component 900 is different, the phase change cold plate 110 may be partially dry, and the phase change in the phase change cold plate 110 may not occur, and in severe cases, the internal temperature of the system may abnormally increase, and the system energy consumption may be too large.

[0055] Secondly, the application also provides an electro-hydraulic integrated distribution module, which is connected with the phase change cold plate 110 and the to-be-cooled component 900 respectively, and can collect the power consumption information of each node to-be-cooled component 900; and control the flow of the fluid in the phase change cold plate 110 according to the power consumption information, so as to adjust the liquid inlet amount of the phase change cold plate 110. Specifically, the electro-hydraulic integrated distribution module can calculate the heat generated by each node to-be-cooled component 900 by collecting the power consumption information of each node to-be-cooled component 900, or calculate the heat generated by the corresponding to-be-cooled component 900 by collecting the cooling capacity information (such as the flow of each liquid supply branch) of each phase change cold plate 110, or calculate the heat generated by the corresponding to-be-cooled component 900 according to the power consumption information and the cooling capacity information, and then control the flow of each liquid supply branch of the phase change cold plate 110 according to the heat generated, so that the liquid fluid entering the phase change cold plate 110 absorbs heat and immediately changes into gaseous fluid; the phase change heat exchange potential of each node phase change cold plate 110 can be maximized, the system heat exchange efficiency can be improved, and the data center energy consumption can be reduced.

[0056] Further, the application further sets a fluid separation module. The fluid separation module separates the gas-liquid mixed state fluid collected from the electro-hydraulic integrated distribution module into gaseous fluid and liquid fluid through gas-liquid separation, and then communicates the separated gaseous fluid and liquid fluid with the liquid cooling heat exchange module 200 through different pipelines. Specifically, the system can quickly separate the gas-liquid mixed state fluid of the phase change 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, and effectively reduces the loss of the cooling fluid.

[0057] Further, the electro-hydraulic integrated distribution module is connected in parallel with a plurality of node phase change cold plates 110 through pipelines. Each node phase change cold plate 110 can be provided with a plurality of series-arranged phase change cold plates or a plurality of parallel-arranged phase change cold plates.

The liquid cooling heat exchange module 200 is connected with the plurality of groups of liquid cooling cabinets 100, and simultaneously cools the high-temperature fluid flowing out of the plurality of groups of liquid cooling cabinets 100 to a preset temperature cooling fluid, and supplies the cooled fluid to each node phase change cold plate 110 in each liquid cooling cabinet 100 through the electro-hydraulic integrated distribution module. The system can ensure efficient heat dissipation, support higher liquid cooling cabinet density, and improve the computing power of the data center.

[0070] Specifically, the second distribution pipeline is provided with two fluid outlets, and the gas-liquid two-phase cooling medium flowing out of the plurality of phase change cold plates 110 is collected through the corresponding second fluid pipelines and then flows into the second distribution pipeline main body, and then is separated by the fluid separation unit in the second distribution pipeline main body. After separation, the gaseous cooling medium flows into the liquid cooling heat exchange module 200 through one of the fluid outlets, and the liquid cooling medium flows into the liquid heat exchange module through the other fluid outlet. By arranging the fluid separation unit in the second distribution pipeline main body, the gas-liquid mixed cooling medium in the second distribution pipeline is divided, and by arranging two fluid outlets on the second distribution pipeline, the gaseous cooling medium and the liquid cooling medium after the division flow into the liquid heat exchange module respectively, so that the gaseous cooling medium flowing out of the phase change cold plate 110 is effectively separated in time, the gas-liquid mixed cooling medium directly enters the liquid cooling heat exchange module 200 is reduced, the heat exchange performance of the liquid cooling heat exchange module 200 is improved, the gaseous fluid can be quickly condensed, the stability of system operation is improved, the energy consumption of system is reduced, and efficient heat dissipation of system is realized.
