Nvidia, Mitsubishi Heavy in talks on AI data center cooling and power

Mitsubishi Heavy has now joined Nvidia’s Partner Network as a Power & Cooling Partner, formalizing work on liquid cooling and 800 VDC power systems for DSX AI infrastructure.

Fact Check
The MHI official press release (mhi.com/news/260716.html) and MHI's official X account (@MHI_Group) both directly confirm that Mitsubishi Heavy Industries joined the NVIDIA Partner Network as a Power & Cooling Partner, working on liquid cooling and 800VDC power systems for NVIDIA DSX-aligned AI infrastructure. These are primary sources from the named entity, fully corroborating the claim.

Summary

Mitsubishi Heavy Industries has joined Nvidia’s Partner Network as a Power & Cooling Partner, turning earlier reported talks into a formal role focused on integrated thermal management and power delivery for Nvidia’s DSX platform. The work centers on 10MW-class chillers and modular cooling platforms paired with an 800 VDC power infrastructure, a design intended to cut conversion losses in electricity-hungry AI facilities. The cooling systems use a closed-loop liquid approach that can operate at inlet temperatures as high as 45 degrees Celsius, aligning with Nvidia’s push toward fully liquid-cooled AI systems while reducing reliance on water-intensive evaporative cooling. Nvidia’s Vladimir Troy, VP of AI Infrastructure, said Mitsubishi Heavy would help build scalable, energy-efficient AI factories. Nikkei Asia first reported discussions between the companies on July 14, and Mitsubishi Heavy confirmed the partnership on July 16. Both companies have pointed to long-dated buildouts, with projects involving partners including SK Group targeting completion in 2028-2029.

Terms & Concepts
  • 800 VDC power infrastructure: A direct-current power distribution setup designed to reduce energy losses versus more traditional alternating-current systems.
  • closed-loop liquid cooling: A cooling system that circulates liquid through a sealed loop to remove heat while minimizing water consumption.
  • modular cooling platforms: Cooling units built as repeatable modules that can be deployed and scaled across large AI data center sites.
