MHI and EXEO deploy Japan’s first two-phase DLC GPUs

Mitsubishi Heavy Industries, Ltd. (MHI) and EXEO Group, Inc. have announced the deployment and start of commercial operation of Japan’s first GPU servers cooled with two-phase direct-to-chip cooling (DLC) at EXEO Group’s data center.

• Two-phase DLC circulates a non-conductive liquid/gaseous refrigerant through cold plates directly on GPU chips, enabling stable cooling of 1,000–1,400W GPUs, reducing fan power, lowering PUE, and mitigating CO2 emissions, operating costs, and failure risks in GPU servers used for generative AI.
• EXEO Group integrates MHI’s heating and cooling technology with its data center construction and operations expertise to deliver a one-stop GPU server service, and both companies plan to expand these low-environmental-impact solutions for large-scale data centers to support green transformation (GX) in the IT sector.
