Single-Phase Immersion Cooling
Single-phase immersion cooling is an advanced thermal management technology designed for high-density computing environments such as AI clusters, high-performance computing (HPC), and modern data centers.
In this approach, servers are fully submerged in a specially engineered dielectric coolant that is electrically non-conductive. The coolant absorbs heat directly from the electronic components, eliminating the need for traditional air cooling systems and significantly improving heat transfer efficiency.
As the coolant flows through the immersion tank, it captures the heat generated by processors, GPUs, memory modules, and power components. The warmed coolant is then circulated through a heat exchanger, where the thermal energy is transferred to a primeryy cooling loop. The primery loop typically rejects heat through a dry cooler, which dissipates heat to ambient air. Depending on the site conditions and cooling requirements, other heat rejection technologies such as cooling towers or chillers can also be integrated.
By removing heat directly at the source, immersion cooling dramatically increases cooling efficiency while reducing the complexity of airflow management within the data center.
