Thermal management has become one of the defining challenges in modern electronics design. Across data centers, AI and machine learning hardware, power electronics, and compact consumer devices, heat generation continues to rise as performance expectations increase. Higher power densities, faster processing speeds, and smaller form factors are placing sustained pressure on … [Read more...]
Monte-Carlo as a Tool for Robust Thermal Design
Introduction Parametric design plots are commonly used in early thermal architecture studies to understand sensitivity across the design space, often resulting in the selection of a single-point solution that achieves a key design objective. For example, the size of a passively cooled consumer electronics device may be selected such that it achieves the required thermal … [Read more...]
High-Performance Copper Tungsten Cold Plates for Direct-to-Chip Single-Phase Liquid Cooling
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...]
Silent Solid-State Cooling: How Ionic Wind Technology Is Reshaping Thermal Design
EDITOR'S NOTE: This article is based on a presentation delivered at Thermal Live Fall 2025 by Mark MacDonald, Thermal Technologist at Ventiva, where he outlined how electrohydrodynamic (EHD) air movers — branded as the Ionic Cooling Engine (ICE) — are redefining thermal system architecture. For decades, electronics cooling has relied on mechanical blowers. Bearings spin, … [Read more...]
