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...]
The Physics of Cooling in Confined Spaces: Advanced Driver Assistance Systems (ADAS) Automotive Electronics
Introduction The evolution of modern automotive engineering is defined by a single, escalating conflict: the demand for massive computing power versus the shrinking physical space available to house it. As vehicles transition from mechanical machines to "computers on wheels," the thermal management of Advanced Driver Assistance Systems (ADAS) has moved from a secondary … [Read more...]
