Liquid Cooling Drives Air Cooling Upgrade The Rise of Wind Liquid Homologous Cooling Architecture

70% of Server Heat Goes to Coolant: Why Wind-Liquid Homologous Architecture Ends Redundant Cooling

Liquid cooling is driving a comprehensive air cooling upgrade through the wind-liquid homologous architecture. In the AI computing era, over 70% of server heat is carried away by circulating coolant, making cold plate liquid cooling mainstream and sharply reducing air conditioning load—yet dual independent air and liquid systems bring redundant investment and low energy efficiency. The innovative homologous structure solves this by pairing dual-coil DX water-cooled terminals with shared cooling towers and cold plate CDUs, enabling unified cold source scheduling while cutting fault risks and operating costs. 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...

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.
