What Is Coolant Hose Routing?_

Coolant hose routing refers to how the supply and return hoses are laid out from the coolant distribution unit (CDU) to each server node's cold plates. Proper routing avoids kinks, sharp bends, and contact with hot components to maintain flow and prevent leaks. It also ensures serviceability by allowing hoses to be disconnected or replaced without disturbing adjacent hardware.

Technical Details

Hoses are typically routed along dedicated cable management arms or vertical raceways to keep them separate from power and data cables. The bend radius must stay within the manufacturer's minimum to avoid flow restriction or hose fatigue. Quick-disconnect fittings are used at the server interface, and hoses are often color-coded (e.g., red for supply, blue for return) to prevent cross-connection. In dense racks, hose routing is planned per chassis position to avoid interference with GPU NVLink cables.

How Leviathan Systems Works with Coolant Hose Routing

During rack assembly, Leviathan Systems field crews install coolant hoses after the CDU and server nodes are mounted, following a site-specific routing diagram. We verify that hoses are secured with proper strain relief and that no hose touches a sharp edge or hot surface before the system is filled and leak-tested.
