The CDU Line That Sends Cold to Every Chip, from Rack to Cabinet

10kW to 2MW, ±0.5°C and GB/T 48023-2026 Compliance: Three Forms of CDU Lineup Beating the First National Standard

AI server racks have passed 1MW and the hub that decides whether cooling capacity reaches every chip precisely is the CDU, with rack-mounted, cabinet and air-liquid forms spanning 10kW to 2MW. Three hard indicators define the line: outlet temperature held within ±0.5°C steady state, flow regulation from 0 to 100%, plus dual-pump hot swap and online maintenance. The first national standard GB/T 48023-2026 caps supply temperature deviation at ±1°C, and the unit beats it. The secondary side carries about 70-75% of system value with the CDU at 30-40%, second only to the cold plate. 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...
