Data Centers With Direct Liquid‐Cooled Servers: Experimental Analysis and Modeling
Energy Science &Engineering, Volume 13, Issue 7, Page 3605-3619, July 2025.Direct liquid cooling enables higher cooling temperatures in data centers, reducing cooling energy demand and enabling waste heat reuse. However, elevated coolant temperatures increase server power consumption and thermal losses to the surrounding air. A TRNSYS‐based model was developed to evaluate these effects and support energy‐efficient data center
