Résumé

Two-phase immersion cooling (2-PIC) is an emerging technology for thermal management of high heat-density server systems used in data centers. With 2-PIC, data centers can significantly reduce energy usage, carbon and physical footprint and enable much higher chip heat rejection rates compared to air-cooled facilities. Dielectric liquids used in 2-PIC today however, either have high GWP, poor dielectric properties or may require stringent contamination controls. In this paper, a new low-GWP 2-PIC fluid candidate is proposed. First, key thermophysical and dielectric properties are compared among multiple fluids. Second, a signal integrity analysis will show that the new fluid has similar cable losses compared to air. Next, results of a successful proof-of-concept testing of the new fluid with actual servers are presented in detail. Finally, a 2-PIC system simulation model is used to demonstrate both the potential of the technology and the new fluid to increase power usage effectiveness (PUE) of data centers.
