Abstract This paper presents a novel thermal management approach for power semiconductor modules by integrating active liquid cooling directly into the substrate. Utilizing Direct Bond Copper (DBC) structures embedded within liquid cold plates, the method minimizes thermal interfaces, improves power density, and ensures better reliability. It contrasts traditional … [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...]
In-Package, Direct-on-chip Liquid Cooling with Lid-Compatible Manifold for Efficient AI Chip Thermal Management
Introduction The advancement of artificial intelligence (AI) has led to an accelerating development of high-performance AI chips, which are increasingly characterized by ultra-large die areas, extreme interconnect density, and high-power consumptions. Heat dissipation is a bottleneck for the next-generation high-power graphics processing unit (GPU) and necessitates advanced … [Read more...]
