EXTRCOOL Builds In-House Manufacturing Capability for Liquid Cooling Cold Plates and Manifolds

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 ...

GPU racks are getting denser and air cooling can no longer carry the heat away, so cold plate direct-to-chip cooling attaches a channeled metal plate to the chip, and the system splits into three sections, the near-end side inside the rack, the CDU exchanging heat between two loops through a plate exchanger, and the outdoor heat sink. A manifold works as the rack-level s...

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...
