The CDU, the Heat-Exchange Logic at the Core of Liquid Cooling

Two Loops, One Plate Wall, 95% Exchange Efficiency: The Indirect-Exchange Design That Keeps Outdoor Water Out of the Server Loop

The CDU works not by producing cold but by transferring heat between the outdoor cold source and the server loop through controlled exchange, and the design rests on two independent loops joined by a plate exchanger so fluids never mix: the primary loop runs to the cooling tower, dry cooler or chiller at 15 to 22 degrees, and the secondary loop carries a dedicated insulating coolant that returns from the servers warmed to 28 to 35 degrees, with the corrugated stainless plates pushing exchange efficiency above 95 percent. Rack power has climbed past 50 kilowatts with some AI centers over 100, and the CDU cuts cooling energy more than 40 percent. EXTRCOOL provides one-stop liquid cooling solutions.

Surface Treatment for Liquid Cooling Manifolds, the Natural-Finish Pickling Process

Matte White to Natural Luster, Blue-Point From 12-18 to Above 20 Seconds: The Two-Stage Route That Removes Weld Scale Without Touching the Base

Surface treatment for liquid cooling manifolds starts from the weld problem: the heat-affected zone triggers intergranular chromium depletion that degrades surface oxidation and roughness, threatening long-term corrosion resistance, and conventional pickling removes the scale but turns the weld grey, rough and the stainless matte white. The natural-finish route runs two ...

The Stainless Manifold, the Hidden Gatekeeper of AI Server Liquid Cooling

One Uneven Split, One Throttling GPU: Why the 120-140kW NVL72 Turned the Manifold Into NVIDIA's Certified Gatekeeper

The stainless manifold is the hidden gatekeeper of AI server liquid cooling: the cold plate sits on the GPU, the CDU handles exchange, the manifold splits one flow into dozens and the quick coupling allows maintenance without breaking the loop, so in an NVL72 cabinet an uneven split lets one GPU drift hot, throttle first or trip protection. Stainless wins on ten-plus-yea...

Manifold and Quick Coupling Selection, the Field Guide for Cold Plate Cooling

0.86 × Heat ÷ ΔT With 20% Margin, Server Thread First, 20 Bar and 5,000 Cycles: The Five-Step Selection That Stops Leaks, Not Just Flow

Manifold and quick coupling selection for cold plate cooling starts with the failure mode: the manifold divides one flow into many branches but its risk lives in the interfaces, so seal reliability outranks flow testing. Sizing follows 0.86 times the heat over the temperature difference with 20 percent margin, a 40 by 40 tube holding 75 liters per minute for 25 to 50 kil...
