Two-stage Liquid Cooling Distribution: In-Row Manifold & In-Rack Manifold
In a typical D2C (Direct-to-Chip) liquid cooling system, the In-Row Manifold serves as the row-side main manifold. It receives coolant from the CDU and distributes supply/return ports to every rack in the row.
Mounted inside each rack, our In-Rack Manifold taps off the fluid circuit from the In-Row Manifold. It further divides the flow into dedicated branches for GPU / CPU cold plates inside the cabinet. Quick-disconnect fittings integrated on the In-Rack Manifold allow individual servers to be removed without draining the In-Row manifold’s row-level piping loop.
This hierarchical design reduces flow imbalance, simplifies leak containment, and lowers downtime during hardware replacement.
