Design and performance analysis of liquid cooling cabinets in dual redundancy architecture
This study proposed a liquid cooling cabinet design scheme under a dual redundant architecture based on the technical requirements of cooling capacity,water supply temperature,and structural dimensions of the cooling object.Based on the installation dimensions of each refrigeration component,a design strategy was adopted to integrate all refrigeration components into three 19 inch cabinets,and the structural characteristics of the three cabinets were assembled together.The three cabinets are divided into"Refrigeration Cabinet #1,""Refrigeration Cabinet #2,"and"Supply Water Cabinet."Among them,two refrigera-tion cabinets provided a cooling capacity of not less than 45 kW each in a"mirror identical"and"redundant backup"manner,while the supply water cabinet provided circulation power for chilled water through the redundancy of two water pumps.The de-sign focuses on the working principle,structural layout,and supply water temperature control technology of the liquidcooling cab-inets.It achieved a cooling capacity of 46 kW and 46.2 kW for"Refrigeration Cabinet #1"and"Refrigeration Cabinet #2,"re-spectively,in seawater heat exchange mode,and 48.8 kW and 49.1 kW in compression refrigeration mode.
