Kidus Guye presented his work on designing and modeling a novel hollow micropillar evaporator for high AI/ML workloads in state-of-the-art data centers for low PUE two-phase cooling. This work is part of the ARPA-e COOLERCHIPS project geared towards developing next-generation liquid cooling technologies with significantly low junction-to-coolant thermal resistance, with PUE lower than 1.02. Also presenting along with Kidus is Karthik Upadhyay, a PhD student under Prof. Sumantha Acharya at the Illinois Institute of Technology. Their group is a close collaborator with UMD, the University of Texas, Arlington, and the University of Illinois, Urbana Champaign on the ARPA-e COOLERCHIPS project to develop the evaporator technology.
