The Manifold That Connects the CDU to Every Chip: Mapping the Global AI Liquid Cooling Supply Chain

CoolIT, Cooler Master, Envicool and Liminda: Reading the Global Manifold Map From OCP to Vera Rubin

As GB200/GB300 NVL72 racks peak at 120-140kW, the manifold—the hub connecting the CDU to every cold plate—demands zero-leak precision, pressure balance and flow control. Taiwan supplies high-end support—Cooler Master is the first core GB200/GB300 manifold vendor with vacuum brazing near zero leakage. Mainland vendors are breaking through: Envicool, the first domestic NVIDIA Tier 1 vendor, covered over 80% of global NVL72 rack deliveries in 2024, and Lingyi Liminda is the only mainland player in Vera Rubin's manifold ecosystem. Competition is shifting from single parts to integrated, helium-tested system delivery and specialty materials. 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.
