Nvidia GB200 liquid cooled manifold

As the power density of AI servers exceeds 200kW/rack, liquid cooling systems have changed from "optional" to "mandatory". As the "vascular hub" of the liquid cooling system, the manifold is responsible for the core function of coolant diversion and convergence, and its performance directly determines the heat dissipation efficiency and system reliability.

The Technical Value and Market Position of Water Dividers

In the Nvidia GB200 NVL72 system, the single unit value of the liquid cooled water separator is as high as $12000, accounting for 12% of the cost of the liquid cooled module, second only to the CDU (coolant distribution unit). The core challenge lies in:

High pressure requirement: Suitable for 100kW+cabinets, with a pressure capacity of ≥ 1.5MPa;
Low flow resistance design: reduces pump power loss, and PUE pressure needs to be reduced to below 1.08;

Intelligent integration: Dynamic adjustment of branch traffic to match GPU load fluctuations.
