Description
一種機櫃伺服器系統,尤其是指一種用於機櫃伺服器的液冷系統。A cabinet server system, particularly a liquid cooling system for a cabinet server.
目前資料中心,絕大多數是使用風冷型空調系統對機櫃伺服器進行冷卻散熱,風冷型空調系統利用風扇的轉動帶動空氣流動,從而帶走機櫃伺服器的熱量。從冷卻的角度看,風冷冷卻主要能耗產生於風冷室外冷凝器,空調及壓縮機等,導致單機系統的能效比較低,目前業界常用的風冷方式能效比(Power Usage Effectiveness,PUE)約為1.5-2.0。At present, most data centers use air-cooled air-conditioning systems to cool and cool cabinet servers. Air-cooled air-conditioning systems use the rotation of fans to drive air flow, thereby taking away the heat from the cabinet servers. From a cooling point of view, the main energy consumption of air-cooled cooling is generated by air-cooled outdoor condensers, air conditioners and compressors, which results in low energy efficiency of the single-machine system. Currently, the industry's commonly used air-cooled cooling method (Power Usage Effectiveness, PUE) About 1.5-2.0.
常規的風冷散熱技術相對比較成熟,風冷散熱所帶來的風機耗能劇增以及雜訊問題,已嚴重阻礙了電腦性能的提高。研究表明,換熱係數與風速關係為h∝u0.8,壓力損失與風速的關係為ΔP∝u 2,產生的雜訊與風速的關係為U∝u 5,這將無法滿足高性能電腦發展的要求。此外,對於高性能伺服器,由於CPU/DIMM等的功耗增加,以及具有較強計算與存儲性能的擴展卡的引入,散熱問題也成為伺服器設計與應用的一個極大挑戰。對於超高功率密度的資料中心來說,風冷技術難以實現對系統的高效散熱。Conventional air-cooled cooling technology is relatively mature. The drastic increase in fan power consumption and noise problems caused by air-cooled cooling have seriously hindered the improvement of computer performance. Research shows that the relationship between heat transfer coefficient and wind speed is h∝u0.8, the relationship between pressure loss and wind speed is ΔP∝u 2, and the relationship between generated noise and wind speed is U∝u 5, which will not meet the development of high-performance computers Requirements. In addition, for high-performance servers, due to the increased power consumption of CPU / DIMMs and the introduction of expansion cards with strong computing and storage performance, heat dissipation issues have also become a great challenge for server design and application. For ultra-high power density data centers, air cooling technology is difficult to achieve efficient cooling of the system.

The automatic control method includes two types of temperature control and flow control. Please also refer to "Figure 5", which is a flowchart of temperature control of the cooling distribution control device according to an embodiment of the present application. As shown in the figure, when the liquid cooling system 1 is in operation, step S10 is performed first to cool the distribution. The first temperature sensor 120 of the control device 11 detects the temperature of the second cooling liquid flowing through the secondary-side output pipe 117 to the secondary-side liquid circulation pipe 13 and generates a first temperature signal to the logic controller 122 . Then step S11 is executed. The logic controller 122 learns the temperature of the second cooling liquid sent to the secondary-side liquid circulation pipeline 13 according to the first temperature signal, and determines whether the temperature of the second cooling liquid is greater than a preset temperature value. When the temperature of the second cooling liquid is greater than the preset temperature value, which indicates that the heat exchange amount of the heat exchanger 111 is lower than the preset heat exchange amount, step S12 is performed to increase the opening degree of the primary control valve 114 and increase the The opening degree is that the logic controller 122 generates a first control signal and transmits the first control signal to the primary control valve 114.

If the heat exchange amount of the heat exchanger 111 is found to be lower or higher than When the heat exchange amount is preset, by controlling the flow rate of the first cooling liquid input to the heat exchanger 111 by the primary-side liquid circulation pipeline 10, the temperature of the first cooling liquid located in the heat exchanger 111 is maintained at a preset temperature value. In addition, the ambient temperature sensor 123 and the ambient humidity sensor 124 sense the temperature and humidity in the environment, respectively, and generate an ambient temperature signal and an ambient humidity signal, and transmit the ambient temperature signal and the ambient humidity signal to the logic controller 122.
