{"data":{"slug":"liquid-cooling","term":"Liquid cooling","question":"What is liquid cooling and why does AI need it?","answer":"Liquid cooling removes heat from computer chips using coolant instead of air, typically through cold plates mounted directly on processors. AI racks now draw so much power that air cooling cannot remove the heat economically, making liquid cooling the default in new AI data center builds and a fast-growing supplier market.","investorNote":"Cooling has shifted from an afterthought to a gating requirement: thermal capacity determines how many accelerators a building can host. Suppliers of cold plates, coolant distribution units, and chillers collect a rising share of each data center's construction budget, and their orders track AI rack deployments directly.","category":"cooling-thermal","related":["gigawatt","colocation","ems"],"faq":{"q":"Which companies benefit from the shift to liquid cooling?","a":"The layer spans specialist liquid-cooling makers, large HVAC and chiller manufacturers reorganizing around data centers, and server assemblers integrating cooling at the rack level. Exposure varies widely, since many also serve commercial buildings and industrial markets, which is what the per-stock AI Exposure Scores on this site measure."}},"meta":{"version":"v1","asOf":null,"builtAt":"2026-11-03T05:33:49.687Z","tier":"free","source":"https://supercyclehq.com/learn/liquid-cooling","disclaimer":"Informational only, not investment advice.
