Liquid Cooling for Data Centers, Advantages, Routes and Coolants

PUE 1.03, No Chillers, No CRAC, No Geography Constraints: Why Liquid Cooling Wins Beyond Simply Moving Heat

Liquid cooling for data centers answers rising per-rack power with advantages beyond heat removal: the same cooling architecture deploys anywhere regardless of geography, design and scaling simplify, and removing air-cooling infrastructure, chillers and CRAC hardware cuts capital and operating cost with PUE dropping to 1.03. Spray jets liquid onto heat sources with mist escape, immersion works single-phase or boiling two-phase, and cold plate circulates liquid without touching equipment. Fluorinated fluid stays the dominant data center medium with superior insulation and non-flammability at premium cost, while mineral oil trades cost for viscosity residue and residual combustion risk. EXTRCOOL provides one-stop liquid cooling solutions.

CDU Commissioning, From Four Measurement Points to the Temperature Budget

P-in 25, S-out 30, Target 28: Why the 5-Degree Approach Exceeds a 3-Degree Budget and Where the Heat Balance Breaks

CDU commissioning starts from four measurement points: P-in for facility water entering as the primary cold inlet, P-out as the primary hot outlet, S-in for server return as the secondary hot inlet, and S-out leaving toward the servers, with the approach temperature defined as S-out minus P-in. With the primary inlet at 25 and supply at 30 against a target of 28, the app...

800VDC Reshapes the CDU, One Booth for Power, Backup and Cooling

1MW Rack, 1/15 Current, 1/225 Line Loss: The 800-Volt Rewrite That Folds CDU, Power Shelf and 5000A Busbar Into One Booth

An 800VDC white paper is rewriting the cabinet: moving a megawatt rack from 54 to 800 volts cuts the current to roughly one fifteenth and line loss to one two-hundred-twenty-fifth, against 200 kilograms of copper busbar and a power shelf eating 64U at low voltage, and the CDU rewrite lands on the input, a 2.5-megawatt liquid-to-liquid unit carrying 800VDC with three hot-...

CDU Selection, Decisions That Shape the Next Decade

Centralized vs Distributed, 105-110% Capacity and a 2-8°C LMTD: The CDU Decisions That Decide Fault Radius and Availability

CDU selection starts with centralized versus distributed: centralized units sit outside the cabinets with secondary piping and must hold rack-to-rack flow variation within 10 percent, widening the blast radius, while distributed units ride inside each cabinet and confine faults to one rack. Design capacity runs 105 to 110 percent of the calculated load on the liquid-cool...
