Support the development of mechanical design basis assumptions, including cooling loads, heat rejection strategies, air management, and emerging liquid cooling requirements for high-performance computing (HPC) and AI workloads.
-
Assist in evaluating different cooling approaches (e.g. air-cooled, chilled water, hybrid and liquid cooling systems) and their impact on efficiency, scalability, and site infrastructure.
