From Home Appliances to AI Compute, Midea's Liquid Cooling Strategy

Liquid cooling rewrites the heat boundary of dense compute: single AI chips have passed 700 watts and rack power moves toward 400 kilowatts where air cooling faces heat flux limits, density capped around a dozen kilowatts and rising fan energy, and a liquid-cooled server runs as a closed loop of cold plate, CDU, pump, manifold and couplings. Three routes answer heat remo...

CDU selection opens with central versus distributed, the hardest decision to reverse: central units sit outside the racks with secondary piping and must hold rack-to-rack differences within about 10 percent, while distributed units ride in each rack, remove secondary piping and confine an outage to one cabinet. Redundancy carries the trap that cold plate servers often ho...

Liquid cooling has moved from the backstage to the thermal foundation of high-density AI compute: most AI chip electricity becomes heat, the GB200 NVL72 packs 72 Blackwell GPUs and 36 Grace CPUs at about 120 kilowatts per rack with CPUs and GPUs liquid-cooled through cold plates while networking stays fan-cooled, and global data center electricity is projected to climb f...
