Global CDU Industry Pattern and In-depth Analysis of Top 20 Liquid Cooling Suppliers

L2L for PUE 1.05, A2L for Retrofit: Mapping the Top 20 Suppliers Across Two Heat Exchange Routes

This analysis of the global CDU industry and top 20 liquid cooling suppliers examines how CDUs—combining plate heat exchangers, circulation and makeup pumps, filters, leak sensors, regulating valves and controllers—perform flow distribution, temperature regulation and pressure balance. Two heat exchange routes dominate: liquid-to-liquid CDUs achieve PUE below 1.05 for new high-density facilities, while air-to-liquid units enable low-cost renovation without chilled water infrastructure. Domestic leaders including Inspur, Invicool, Schneider and Delta face international suppliers Vertiv, Nidec, CoolIT and LiquidStack with long-term NVIDIA, Meta and Microsoft partnerships. 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...

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.
