Three Main Liquid Cooling Technologies for Modern Data Centers D2C Immersion and RDHx

Cold Plates for New Builds, Rear Doors for Retrofit, Immersion for Ultra-Density: Choosing Your Route

Three mainstream liquid cooling technologies serve modern data centers. Direct-to-Chip (D2C) cooling circulates coolant through cold plates directly above CPUs and GPUs in a closed loop driven by onboard pumps, with CDUs removing up to 80kW, variable-frequency load matching and rack-mounted layouts shortening pipelines. Rear Door Heat Exchanger (RDHx) offers a retrofit-friendly alternative where built-in fans cool hot rack exhaust in real time, cutting CRAC load without major infrastructure modification. Immersion cooling submerges entire servers in non-conductive, non-corrosive liquid, where component heat warms the coolant, causing natural rise before external cooling and recirculation. 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.
