Delta Power and Liquid Cooling Solutions for NVIDIA AI Data Centers

PUE Below 1.1 and 200kW Rack Density: Delta's HEC System Powers NVIDIA's Blackwell and Rubin Platforms

Delta Electronics has become NVIDIA's most important core supplier for power and liquid cooling. Beyond AI server power supplies—where it holds top global share—Delta co-develops the 800V HVDC architecture for Blackwell and Rubin platforms with up to 98% efficiency. Its HEC Cold Plate Liquid Cooling Rack System achieves data center PUE below 1.1, supporting 200kW rack density with centralized CDUs up to 2400kW, and pairs DC48V shelves with lithium batteries for 5% gains. EXTRCOOL offers dual-mode CDUs, manifolds, cold plates, rear-door heat exchangers, dry coolers and containerized systems for high-density AI and HPC data centers.

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.
