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...]
Simulation of Two-Phase Microchannel Heat Sink Performance: Refrigerant, Inlet Conditions, and Hot Spots Effects
Introduction The introduction of large language models (LLM), such as ChatGPT, has made artificial intelligence highly accessible. One of the key driving forces behind this growth has been the advancement in the processing power of compute devices such as central processing units (CPUs) and graphics processing units (GPUs). An increase in this processing power is … [Read more...]
