Context Before
Consider Schneider’s GB300 Reference Design 111, presented in September 2025, as another example.
Evidence
In this reference design, the datacenter uses a dual-loop architecture: a chilled-water loop dedicated to air cooling and a separate, higher-temperature loop dedicated to liquid cooling.
Context After
On the liquid side, the TCS circulates coolant to the cold plates at roughly 40C and returns it at a higher temperature, while the CDU transfers that heat into the facility water loop, which can enter the CDU at approximately 37C.
② Atomic Claim
該 reference design 的 datacenter 採 dual-loop architecture：一個 chilled-water loop 專供 air cooling，另一個獨立、溫度較高的 loop 專供 liquid cooling。
