Liquid cooling infrastructure

Concentrated CDU and cold plate suppliers command premiums during shortages while custom manifold fabricators capture elevated margins.

Equipment moving liquid coolant directly to chips and servers includes direct-to-chip cold plates, coolant distribution units, manifolds, rear-door heat exchangers and full immersion tanks. Liquid cooling handles 1000W+ per GPU in modern AI clusters where air cooling fails. CDU makers and cold plate suppliers command premiums amid supply shortages; custom manifold fabricators also capture elevated margins.

What the evidence shows

CDU lead times currently run 12-18 months for quality units.

Chiller lead times run 20 to 30 weeks under normal conditions.
