Mitsubishi Heavy Industries, a company best known for building things like jet engines and nuclear power plants, is now officially in the business of keeping Nvidia’s AI factories from overheating. MHI has joined Nvidia’s Partner Network as a Power & Cooling Partner, tasked with developing integrated thermal management and power delivery systems for Nvidia’s DSX platform.
Think of it as the industrial equivalent of strapping a radiator to a supercomputer, except the radiator weighs several tons and uses closed-loop liquid cooling capable of operating at inlet temperatures as high as 45°C.
What MHI is actually building
The partnership centers on two core technologies: 10MW-class chillers and modular cooling platforms, or MCPs. MHI’s systems will pair high-efficiency thermal management with an 800 VDC power infrastructure. That’s a significant design choice. Direct current power distribution at 800 volts reduces conversion losses compared to traditional AC setups, which matters enormously when you’re talking about facilities that consume electricity at industrial scale.
The closed-loop cooling approach is particularly notable. Traditional data center cooling often relies on evaporative systems that consume vast amounts of water, a growing concern as AI infrastructure expands into regions facing water scarcity. Nvidia’s DSX vision calls for systems that can operate with minimal water consumption while still handling the extreme heat densities that modern AI accelerators produce.
Vladimir Troy, Nvidia’s VP of AI Infrastructure, highlighted MHI’s role in building scalable, energy-efficient AI factories.
The broader AI infrastructure race
The timing of this partnership is no accident. Nikkei Asia first reported discussions between the two companies on July 14, with MHI’s official confirmation following on July 16. Both companies have referenced ambitious timelines, with key projects involving partners such as SK Group targeting 2028-2029 completion.
