A new market analysis projects the data center liquid cooling sector will grow to $17.8 billion by 2036, driven by hyperscale AI infrastructure deployments requiring advanced thermal management solutions. The report attributes growth to the increasing heat density of GPU-based AI training clusters, which air cooling systems cannot adequately manage. Vendors including direct liquid cooling and immersion cooling providers are expected to capture the bulk of new investment. The forecast underscores why companies such as Johnson Controls and multiple liquid cooling specialists are accelerating product development and partnerships.
