This paper presents a rack level Hybrid Liquid Cooling System (HLCS) that couples direct-contact liquid cooling with a rear door cooler air-to-water heat exchanger. The rack-level Hybrid Liquid Cooling System presents a unique entry point to achieving much higher efficiencies of liquid cooling as well as built-in components that provide flexibility and scalability for attaining additional efficiencies long term.
