Context Before

The shift from liquid + air to 100% liquid systems, combined with higher flow rates and greater cooling capacity, will require changes across the cooling stack. Fans and radiators used in L2A CDUs will become less critical over time. That said, L2A is likely to maintain meaningful share during the current upcycle, where deployment speed matters more than full optimization, though the long-term trajectory clearly favors L2L. High-density L2L systems will also require redesigns across much of the TCS.

Evidence

This includes updated manifolds, larger quick disconnects (Colder Products Company, Danfoss, Staubli, Parker Hannifin), gold-plated cold plates (AVC, Delta, Boyd, CoolIT, Auras) and, very critically, larger pumps capable of delivering the required water volume.

Context After

Pump sizing is directly linked to power density and the heat that must be removed.

② Atomic Claim

這些變更包括 updated manifolds、更大的 quick disconnects、鍍金的 cold plates，以及能提供所需 water volume 的更大型 pumps；原文同時列出各類供應商。
