Rack Level High Density Liquid Cooling
Increased heat densities of IT Equipment (ITE) in high performance data centers continues to drive the need for more efficient and effective cooling technologies. Traditional air cooling is not a sustainable solution in these settings. While liquid cooling offers far greater efficiencies than air cooling, many liquid cooling options require large capital expenditures, are difficult to integrate with existing infrastructure, and present complications when upgrades or added capacity are needed.
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.
