Cooling an embedded computing system for military vehicles, weapon systems, and other platforms becomes more challenging every year. The newest generation of COTS modules and AI-centric processors are smaller and more capable than their predecessors. However, these newer designs are susceptible to overheating — especially with some of the newer 3U OpenVPX modules operating within the 50W-75W range, while other GPU and high-end FPGAs can hit the 175W range. These OpenVPX architectures, defined and maintained under VITA standards such as VITA 46 and VITA 48, continue to evolve to support higher power densities and corresponding thermal-management requirements. Thermal loads are ramping up faster than ever.
