Liquid Cooling Technology Selection Guide for High-Density AI Data Centers

Cold Plate for Retrofit, Spray for Balance, Immersion for Extremes: The AI Data Center Selection Map

Liquid cooling has become the key solution for high-density AI data centers as rising rack power exceeds air cooling's physical limits. Three mainstream routes serve differentiated scenarios: cold plate liquid cooling—preferred for legacy renovation with strong compatibility, low investment and easy maintenance, ideal below 30kW; spray liquid cooling—a cost-effective intermediate offering better cooling than cold plates at moderate transformation difficulty for medium-to-high density IDC; and immersion liquid cooling—delivering the highest heat dissipation with servers fully soaked in insulating coolant, cutting PUE and extending hardware life for ultra-high-density new builds. EXTRCOOL provides one-stop full liquid cooling solutions.

The CDU, the Heart and Brain Liquid Cooling Cannot Do Without

Silent When Healthy, Fatal When Failing: The Five Selection Questions That Decide Whether the CDU Holds the Loop Together

The CDU plays the role the heart plays: it produces no cold, but without it the coolant never moves. Its heart role pumps and distributes via the manifold, while its brain role senses and controls. Selection answers five questions: total flow above all cold plate minimums, head above maximum loop resistance, exchanger capacity above peak load with fouling margin, redunda...

The Manifold That Decides Where the Coolant Goes

From CDU to Cold Plate and Back: How the Manifold's Flow Distribution, Not Total Flow, Decides Precision Cooling

Rising AI GPU power is moving liquid cooling from whether it can cool to cooling precisely, and the manifold decides whether coolant reaches every position as it should. It distributes coolant through main channels to parallel branches and collects the heated return, following CDU to supply manifold to cold plate to return manifold to CDU. Poor design lets near-end branc...

How a Liquid Cooling Manifold Gets Made, from Material to Final Acceptance

316L to Helium Testing: The Four Links—Material, Machining, Cleanliness and Verification—That Decide Manifold Quality

Manifold manufacturing starts with material, and 316L is the safer default, with coolant compatibility outweighing thermal conductivity. CNC machining forms main channels, branches and interface holes, where holding channel positions matters more than drilling; one-piece machining avoids weld deformation, while tube and plate assemblies add laser, TIG or brazing.
