Space-Station Tech Pivots to Cool AI Data Centers
Summary
Mikros Technologies and Carbice Corporation are adapting technology originally developed for the International Space Station to address critical heat dissipation challenges in AI data centers. Mikros, acquired by Jabil in 2025, specializes in microchannel liquid cooling, partnering with Broadcom for its 5-kW XPU custom accelerators and Marvell for co-packaged optics chips. Their MikroMatrix design precisely distributes coolant to match GPU power maps, ensuring even cooling and enabling higher rack densities. Carbice Corporation provides carbon nanotube Thermal Interface Materials (TIMs) that mechanically adjust to chip curvature changes, preventing performance throttling. Carbice's material increases surface area for convection by over 10,000 and has been tested on Nvidia chips at Georgia Tech for three years. These innovations are crucial given increasing chip heat emission, which caused a May 7 Amazon data center shutdown, and data centers' projected 12% of total U.S. electricity consumption by 2030. Liquid cooling can cut over a third of energy consumption from air-cooled data centers and save over \$1 million per rack lifetime.
Key takeaway
For AI Hardware Engineers and MLOps teams designing or upgrading high-density data centers, you must prioritize advanced thermal management. Integrating microchannel liquid cooling, like Mikros's MikroMatrix, and adaptive carbon nanotube TIMs, such as Carbice's, is crucial to prevent costly throttling events and maximize full ASIC performance. This approach ensures system stability, reduces energy consumption by over a third, and supports the 5-kW XPU demands of future AI compute.
Key insights
Space-station derived liquid cooling and carbon nanotube TIMs are critical for managing extreme heat in next-gen AI data centers.
Principles
- Chip heat emission drives demand for advanced cooling.
- Liquid cooling significantly reduces energy consumption.
- TIMs must adapt to chip curvature changes.
Method
Mikros's MikroMatrix design uses a matrix array of microchannels perpendicular to the chip surface to distribute coolant, matching GPU power maps for even, efficient cooling. Carbice's carbon nanotube TIMs mechanically adjust to chip curvature.
In practice
