AI Computing Advancement and Carbon Regulations Drive Global Liquid Cooling Industry Expansion

GB200 at 1200W, Rubin at 2300W, Market Up 303%: The Physics-Policy Double Engine of Liquid Cooling

AI computing advancement and carbon regulations drive global liquid cooling expansion as NVIDIA's GB200 chips reach 1000-1200W TDP and Rubin climbs to 2300W, pushing racks beyond air cooling limits while PUE-below-1.25 mandates make liquid cooling a rigid requirement; the global AIDC market will hit 88.2 billion yuan in 2026, up 303% year on year. Cold plates and CDUs account for nearly 80% of component value. As control hubs, CDUs manage circulation, temperature, pressure and leakage for megawatt clusters, with EU-compliant and UL-certified models meeting regional thresholds and high-density units supporting 200kW+ racks. EXTRCOOL provides one-stop 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...

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.
