Diagram showing the layout of a liquid immersion cooling pod. The top volume holds the server hardware (depicted as hot) and coolant. The coolant is circulated by a pump to a heat exchange with facility chilled water, such that hot coolant and cool water enter and cool coolant and hot water exit each system respectively.

Abstract

The growing need for energy-efficient computing has led to many novel system innovations, including liquid immersion cooling. While many myths about the technology have been dispelled, the actual impact of this cooling solution on thermal conditions in real computing scenarios remains under-reported and under-studied. In this work, we collate data from multiple system monitoring tools to perform case-study analyses of the thermal behaviors of immersed hardware, aiming to evaluate the effectiveness of liquid immersion cooling for high-performance and datacenter applications.
