Why AI Data Centers Are Moving Cooling Closer to the Chip
Dense accelerators put more heat into each rack, and liquid cooling changes how facilities carry it away.
Cold plates sit against processors and transfer heat into a circulating liquid. A distribution unit passes that heat to the building loop. Fans can still serve storage, networking gear and other components outside the liquid circuit.
Retrofitting a room means checking pipe routes, floor loads and space to disconnect a rack. Leak detection and maintenance access matter because a cooling fault can remove several servers at once.
Compare the power used by the whole cooling system across seasons, including pumps and heat rejection. The result depends on the building and local climate as well as the rack design.
