Hyperscale data center operators are accelerating the replacement of traditional air-cooling systems with direct-to-chip liquid cooling technology across high-density facilities.
Thermal Efficiency Demands
Next-generation GPU and TPU racks exceeding 40 kW per cabinet exceed the physical cooling capacity of forced air. Liquid cooling loops reduce Power Usage Effectiveness (PUE) metrics from 1.4 to under 1.15 in newly constructed facilities.
Retrofit Challenges
Retrofitting existing facilities requires substantial structural modifications to handle fluid distribution units and increased floor weight loads, driving up capital expenditure costs per megawatt.
