TL;DR: In this paper, a water-cooled integral heat sink for silicon integrated circuits has been designed and tested at a power density of 790 W/cm2, with a maximum substrate temperature rise of 71°C above the input water temperature.
Abstract: The problem of achieving compact, high-performance forced liquid cooling of planar integrated circuits has been investigated. The convective heat-transfer coefficient h between the substrate and the coolant was found to be the primary impediment to achieving low thermal resistance. For laminar flow in confined channels, h scales inversely with channel width, making microscopic channels desirable. The coolant viscosity determines the minimum practical channel width. The use of high-aspect ratio channels to increase surface area will, to an extent, further reduce thermal resistance. Based on these considerations, a new, very compact, water-cooled integral heat sink for silicon integrated circuits has been designed and tested. At a power density of 790 W/cm2, a maximum substrate temperature rise of 71°C above the input water temperature was measured, in good agreement with theory. By allowing such high power densities, the heat sink may greatly enhance the feasibility of ultrahigh-speed VLSI circuits.

TL;DR: In this paper, the authors focus on flow through passages with hydraulic diameters from about 1μm to 3 mm, covering the range of microchannels and minichannels, and the challenge is to understand and quantify how utilizing microscale passages alters fluid flow patterns and the resulting, momentum, heat, and mass transfer processes to maximize device performance while minimizing cost, size, and energy requirements.
Abstract: In the last few decades, new frontiers have been opened up by advances in our ability to produce microscale devices and systems. The numerous advantages that can be realized by constructing devices with microscale features have, in many cases, been exploited without a complete understanding of theway the miniaturized geometry alters the physical processes. The augmentation of transport processes due to microscale dimensions is taken advantage of in nature by all biological systems. In the engineered systems that are the focus of this book, the challenge is to understand and quantify how utilizing microscale passages alters the fluid flow patterns and the resulting, momentum, heat, and mass transfer processes to maximize device performance while minimizing cost, size, and energy requirements. In this book, we are concerned with flow through passages with hydraulic diameters from about 1μm to 3 mm, covering the range of microchannels and minichannels. Different phenomena are affected differently as we approach microscales depending on fluid properties and flow conditions; hence, classification schemes that identify a channel as macro, mini, or micro should be considered merely as guidelines. The main topics covered in this book are single-phase gas flow and heat transfer; singlephase liquid flow and heat transfer; electrokinetic effects on liquid flow; flow patterns, pressure drop, and heat transfer in convective boiling; flowpatterns, pressure drop, and heat transfer during convective condensation, and finally biological applications. The coverage is intended to reflect the status of our current understanding in these areas. In each chapter, the fundamental physical phenomena related to the specific processes are introduced first. Then, the engineering analyses and quantitative methods derived from theoretical and experimental work conducted worldwide are presented. Areas requiring further research are clearly identified throughout as well as summarized within each chapter. There are two intended audiences for this book. First, it is intended as a basic textbook for graduate students in various engineering applications. The students will find the necessary foundation for the relevant transport processes in microchannels as well as summaries of the key models, results, and correlations that represent the state-of-the-art. To facilitate the development of the ability to use the new information presented, each chapter contains several solved example problems that are carefully selected to provide practical guidance for students as well as practitioners. Second, this book is also expected to serve as a source book for component and system designers and researchers. Wherever possible, the range of applicability and uncertainty of the analyses presented is provided so that analyzing newdevices and configurations can be done with knownlevels of confidence. The comprehensive summary of the literature included in each chapter will also help the readers identify valuable source material relevant to their specific problem for further investigation.
