Progressive liquid-cooling retrofit for general data centers

Scenario analysis

Unable to shut down and rebuild

Long-running critical services leave limited shutdown windows
Full retrofit involves power distribution, cooling, cabinets, and other systems

Air-cooling efficiency becomes insufficient

High-heat-density cabinets easily create local hotspots
Air-cooling heat dissipation approaches its bottleneck

Data center PUE remains high

Fans and airflow organization consume large amounts of power
Cooling-system efficiency struggles to meet green data center requirements

Retrofit budget is limited

Building a new liquid-cooled room requires high investment
Existing servers and cabinet resources need to continue being used

Solution architecture
