Liquid Cooling for AI Data Centers, From Optional to Non-Negotiable

The cooling distribution unit sits at the center of liquid-cooled thermal management, accounting for 30 to 40 percent of system cost by linking cooling towers, dry coolers and chillers to the secondary server loop through a brazed 316L plate heat exchanger that keeps high-purity deionized water apart from industrial water while handling heat exchange, isolation, precise ...

Cold plates, manifolds, connectors and pipes carry barriers in structural design, precision machining, welding and reliability testing, and project delivery faces process control difficulty, capacity fluctuation, supply interruption risk and a DFM gap between design and manufacturing. EXTRCOOL takes outsourced manufacturing of AI compute liquid cooling components with in...

A manifold distributes coolant from the CDU to each cold plate and collects heated liquid back, and the core problem is flow balancing not water splitting, since header pressure changes cause maldistribution, throttling one server and starving another. Standards hold branch flow deviation within 10 percent and imbalance under 15 percent. Three structures: straight-throug...
