[0032] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0033] like Figure 1 As shown, this application provides a server cooling system, including a single-phase cooling circulation pipeline and a two-phase cooling circulation pipeline.

[0034] The single-phase cooling circulation system includes a primary-side circulation pipe, a heat exchanger 11, and a secondary-side circulation pipe. The cold source 0 is connected to the primary-side circulation pipe to provide the initial cooling medium. The primary-side and secondary-side circulation pipes are respectively connected to the heat exchanger 11, which facilitates heat exchange between the primary and secondary cooling media, transferring heat from the server side to the cold source 0. The heat exchanger 11 is preferably a plate heat exchanger, due to its compact structure and high heat exchange efficiency, which effectively improves the overall heat dissipation performance of the system.

[0035] The two-phase cooling circulation pipeline includes a condenser 10, which is connected to the secondary circulation pipeline of the single-phase cooling circulation pipeline and is used to receive the cooling medium from the secondary side. The single-phase cooling circulation pipeline can not only directly cool the server, but also provide auxiliary cooling support for the two-phase cooling circulation pipeline through the synergistic effect of the heat exchanger 11 and the condenser 10, thereby flexibly adjusting the cooling intensity under different operating conditions.

[0036] This system combines single-phase and two-phase cooling circulation pipes, enabling it to utilize the high-efficiency heat dissipation capacity of two-phase cooling under high load conditions, while relying on the stable operation of single-phase cooling under medium and low load conditions, thus achieving an optimized balance between cooling efficiency and energy consumption. Furthermore, the condenser 10 in the two-phase cooling circulation pipes forms a heat exchange relationship with the secondary circulation pipes of the single-phase cooling circulation pipes, further improving the utilization rate of the cold source 0 and ensuring the stable operation of the server under complex operating conditions.

[0037] In one specific embodiment of this application, the primary-side circulation pipeline adopts a closed-loop design, consisting of a primary cold flow pipe 1, a primary hot flow pipe 2, and a primary pump 3 forming a complete circulation loop. The inlet end of the primary cold flow pipe 1 is directly connected to the outlet of the cold source 0, and its outlet end is connected to the primary-side inlet of the heat exchanger 11, ensuring that the cooling medium is stably delivered from the cold source 0 to the heat exchanger 11. The inlet end of the primary hot flow pipe 2 is connected to the primary-side outlet of the heat exchanger 11, and its outlet end is connected to the return port of the cold source 0, allowing the cooling medium after heat exchange to return to the cold source 0 for further cooling. The primary pump 3, as the circulation power source, can be selectively installed at an appropriate position on the primary cold flow pipe 1 or the primary hot flow pipe 2 to drive the coolant to flow continuously in the circulation pipeline.

[0038] The primary-side circulation pipeline operates as follows: coolant, after being output from cold source 0, enters the primary side of heat exchanger 11 via primary cold flow pipe 1, where it exchanges heat with the secondary-side circulation pipeline. After heat exchange, the coolant temperature rises and returns to cold source 0 via primary hot flow pipe 2 for cooling, forming a complete cooling cycle. The operating parameters of primary pump 3 can be adjusted according to the system's cooling requirements to optimize coolant flow and reduce energy consumption. This not only ensures efficient circulation of the cooling medium but also facilitates heat transfer with the secondary-side circulation pipeline through heat exchanger 11, providing a stable basic cooling capacity for the entire cooling system.

[0039] In one specific embodiment of this application, the secondary-side circulation pipeline consists of a secondary cold flow pipe 4, a secondary hot flow pipe 5, and a secondary pump 6 forming a closed-loop circulation system. The inlet end of the secondary cold flow pipe 4 is connected to the secondary-side outlet of the heat exchanger 11, and the outlet end is connected to the coolant inlet of the server and the coolant inlet of the condenser 10, forming a parallel cooling path. The inlet end of the secondary hot flow pipe 5 simultaneously receives the medium flowing out of the coolant outlets of the server and the condenser 10, and the outlet end returns to the secondary-side inlet of the heat exchanger 11 to complete the circulation loop. The secondary pump 6, as a circulation power unit, can be arranged at a suitable position in the secondary cold flow pipe 4 or the secondary hot flow pipe 5 to maintain the circulation flow of the coolant.

[0040] The operation of the secondary circulation pipeline is as follows: the low-temperature coolant, cooled by heat exchanger 11, is diverted to the server and condenser 10 via secondary cold flow pipe 4, where its temperature rises after absorbing heat. The heated coolant then collects in secondary hot flow pipe 5 and returns to heat exchanger 11 for secondary cooling. This parallel structure allows the system to select either the server or condenser 10 for cooling based on actual operating needs, or to provide cooling for both simultaneously. The speed of the secondary pump 6 can be dynamically adjusted according to changes in cooling load, ensuring that the coolant flow rate matches the system's heat dissipation requirements. This optimizes the allocation of cooling resources and, through the heat exchanger 11 and the primary circulation pipeline, forms a heat exchange linkage, effectively improving the thermal management efficiency of the entire cooling system.

[0041] In one specific embodiment of this application, the two-phase cooling circulation pipeline adopts the phase change heat transfer principle, mainly consisting of a liquid storage chamber 7, a liquid phase pipe 8, and a gas phase pipe 9 to form a phase change cooling circuit. The liquid storage chamber 7 adopts a closed structure design, and a condenser 10 is installed inside it to realize gas-liquid phase change conversion. The inlet end of the liquid phase pipe 8 extends into the liquid storage chamber 7 and is submerged below the coolant surface, and the outlet end is connected to the coolant inlet of the server; the inlet end of the gas phase pipe 9 is connected to the coolant outlet of the server, and the outlet end extends into the liquid storage chamber 7 and is located above the coolant surface.

[0042] The two-phase cooling circulation pipeline operates as follows: the liquid cooling medium is transported to the server interior through the liquid phase pipe 8, where it absorbs heat generated by the server and undergoes a phase change to become gaseous. The gaseous cooling medium then returns to the liquid storage chamber 7 through the gas phase pipe 9, where it re-condenses into a liquid state upon contact with the built-in condenser 10, completing the phase change cycle. The condenser 10 transfers the heat from the gaseous cooling medium to the secondary circulation pipeline through heat exchange, achieving effective heat transfer. This phase change heat transfer-based cooling method fully utilizes the high latent heat of vaporization of liquids, enabling efficient heat dissipation at relatively low flow rates, and is particularly suitable for cooling the high heat flux density areas of the server. The entire circulation process requires no additional power source; the cooling medium circulates autonomously based on the pressure difference generated during the phase change process, featuring a simple structure and reliable operation.

[0043] In one specific embodiment of this application, the liquid phase pipe 8 and the gas phase pipe 9 adopt a branched structure, with multiple parallel first branch pipes arranged on the main pipeline to form a multi-channel cooling network. Each first branch pipe of the liquid phase pipe 8 is connected to the corresponding server coolant inlet, and each first branch pipe of the gas phase pipe 9 is connected to the corresponding server coolant outlet. The liquid cooling medium is evenly distributed to each server through the first branch pipes of the liquid phase pipe 8. After heat exchange is completed, the gaseous cooling medium generated by each server is collected and returned to the liquid storage chamber 7 through the corresponding first branch pipe of the gas phase pipe 9.

[0044] In one specific embodiment of this application, the server cooling system is further configured with an intelligent control component, which establishes a real-time signal connection with a liquid level sensor installed inside the liquid storage chamber 7. The liquid level sensor continuously monitors the liquid level of the coolant in the liquid storage chamber 7 and transmits the detection data to the control component for processing in real time. The control component has a preset safe operating threshold. When the received liquid level data is lower than the preset height, the control component immediately triggers a protection mechanism, forcing the system to stop working, effectively preventing a decrease in phase change cooling efficiency or system idling due to insufficient coolant, and avoiding potential equipment overheating damage.

[0045] In one specific embodiment of this application, the server cooling system includes temperature sensors and / or pressure sensors installed on single-phase and two-phase cooling circulation pipes. The temperature sensors monitor the temperature changes of the cooling medium within the pipes in real time, while the pressure sensors continuously collect pressure data from the pipe system. All sensors establish bidirectional signal connections with the control component via wired or wireless communication, forming a complete monitoring and feedback system. When the monitored data exceeds a preset safety range, the control component can automatically adjust the operating parameters of the primary pump 3 or the secondary pump 6, or trigger a corresponding protection mechanism. This distributed sensing design enables comprehensive monitoring of the cooling system's operating status, providing reliable data support for intelligent system control and fault early warning. Simultaneously, the historical operating data collected by the sensors can also be used to analyze the system's energy efficiency performance, providing a reference for subsequent optimization and maintenance.

[0046] In one specific embodiment of this application, the server cooling system includes a regulating valve installed on a single-phase cooling circulation pipeline. The regulating valve is signal-connected to a control component to regulate the flow rate of coolant entering the server and / or condenser 10.

[0047] When server load changes, leading to altered cooling demands, the control component receives feedback signals from temperature sensors. After data processing, it generates corresponding control signals. The regulating valve adjusts its opening in real time based on these signals, thereby altering the ratio of coolant flow into the server and condenser 10. This closed-loop control mechanism enables precise allocation of cooling resources, ensuring sufficient cooling capacity in high-load areas while preventing overcooling in low-load areas. Furthermore, the coordinated operation of the regulating valve and control component allows for switching between various control modes based on system operating conditions, including but not limited to proportional regulation and PID control, improving the cooling system's energy efficiency and response speed.

[0048] In one specific embodiment of this application, the secondary cold flow pipe 4 and the secondary hot flow pipe 5 are provided with multiple second branch pipes connected in parallel to provide cooling for multiple servers at the same time. The second branch pipes do not interfere with each other, ensuring that each server obtains a stable cooling effect.

[0049] This application also provides a server including the server cooling system of the above embodiments, and therefore also has the advantages of the server cooling system of the above embodiments.

[0050] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
