Cooling system for electronic server racks using two-phase fluids
The granted patent US12048127B2 describes an innovative electronic rack designed to enhance the cooling efficiency of server chassis containing electronic devices. The electronic rack features a coolant management unit that includes a supply region for receiving coolant, a liquid merging region for distributing the coolant to the server chassis, and a separation region for managing the byproducts of the cooling process. The coolant operates by absorbing heat from the electronic devices and transforming into a two-phase fluid, which consists of a liquid portion and a non-liquid portion. A three-way valve is incorporated to selectively manage the flow of these fluids, ensuring optimal cooling performance.
Additionally, the patent outlines several enhancements to the coolant management system, including a liquid level sensor to maintain appropriate coolant levels, a pump to facilitate coolant circulation, and temperature sensors to adjust the coolant flow based on the thermal needs of the server chassis. The separation region employs a de-entrainment mesh pad to effectively separate vapor from the liquid portion of the two-phase fluid, allowing for efficient recycling of the coolant. The design also includes compartments for managing the flow of the two-phase fluid, ensuring that both the liquid and non-liquid portions are effectively handled. This comprehensive cooling system aims to improve the thermal management of electronic racks, thereby enhancing the performance and longevity of the electronic devices housed within.
