In April 2025, Google announced its 1 MW 42U rack [1], marking a turning point in data center thermal management where traditional air cooling can no longer support the extreme power densities of modern hardware. As chip thermal design power (TDP) continues to grow, data centers must replace air-cooled heat sinks with liquid-cooled cold plates [2]. Cold plates transfer heat … [Read more...]

Spacecraft Thermal Control in Extreme Environments: Surviving Lunar Night and Martian Dust
Abstract Extreme conditions in interplanetary environments, like lunar night at -173°C and Martian dust storms, require new thermal control systems that go beyond traditional electronics cooling approaches. Martian dust consists primarily of iron-oxide and silicate particles with diameters ranging from 1 to 3 μm. These particles are electrostatically adhesive, capable of … [Read more...]
Rethinking Thermal Design Priorities in Electronics Packaging
Steady state operating temperature is a critical design parameter for ensuring the reliable operation of modern electronics systems. However, in practice it is but one of many factors that impact overall system health and performance. Modern challenges, like the large transient power draw associated with artificial intelligence (AI) workloads create the potential for more … [Read more...]
