This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The miniaturization of electronic components has resulted in higher heat generation on a smaller surface area, creating a desire for better heat removal techniques and systems. To improve the performance of the pool boiling system, high critical heat flux and low surface temperatures are desired for efficient heat removal. External structures are one technique that seeks to improve pool boiling performance by passively regulating the flow of vapor away from the boiling surface. The present work seeks to study the effect of dual-taper manifold inlet gap height and taper angle on boiling performance through a parametric study with a copper boiling surface of 34.5 mm x 32 mm. perfluoromethylcyclopentane (PP1C) was used in a closed loop pool boiling system at atmospheric pressure. The current study looks at the design parameters of the dualtaper manifold to study the effect on boiling performance by testing dual-taper manifolds with 0.5mm, 1mm, and 1.5mm inlet gap heights and 10, 15, and 20 degree taper angles and comparing the results to those obtained from a plain test chip. At 0.5mm, critical heat flux (CHF) was worse overall, while heat transfer coefficient (HTC) only showing marginal improvement with a 20 degree taper angle. At 1mm manifold height, CHF was improved at 15 and 20 degree taper angles, while HTC improved with 10 and 15 degree taper angles. At 1.5mm, CHF was slightly reduced at 10 and 20 degree taper angle while marginally improved with a 15 degree taper angle, while peak HTC was marginally improved for all taper angles. The overall poor performance is attributed to long residence time and the poor liquid-vapor density of PP1C and dual-tapered manifolds are not recommended as a pool boiling enhancement technique with similar fluids"--Abstract.

Download or read book Chips 2020 written by Bernd Hoefflinger and published by Springer Science & Business Media. This book was released on 2012-01-19 with total page 497 pages. Available in PDF, EPUB and Kindle. Book excerpt: The chips in present-day cell phones already contain billions of sub-100-nanometer transistors. By 2020, however, we will see systems-on-chips with trillions of 10-nanometer transistors. But this will be the end of the miniaturization, because yet smaller transistors, containing just a few control atoms, are subject to statistical fluctuations and thus no longer useful. We also need to worry about a potential energy crisis, because in less than five years from now, with current chip technology, the internet alone would consume the total global electrical power! This book presents a new, sustainable roadmap towards ultra-low-energy (femto-Joule), high-performance electronics. The focus is on the energy-efficiency of the various chip functions: sensing, processing, and communication, in a top-down spirit involving new architectures such as silicon brains, ultra-low-voltage circuits, energy harvesting, and 3D silicon technologies. Recognized world leaders from industry and from the research community share their views of this nanoelectronics future. They discuss, among other things, ubiquitous communication based on mobile companions, health and care supported by autonomous implants and by personal carebots, safe and efficient mobility assisted by co-pilots equipped with intelligent micro-electromechanical systems, and internet-based education for a billion people from kindergarden to retirement. This book should help and interest all those who will have to make decisions associated with future electronics: students, graduates, educators, and researchers, as well as managers, investors, and policy makers.

Download or read book Nanoscale Semiconductor Memories written by Santosh K. Kurinec and published by CRC Press. This book was released on 2017-07-28 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nanoscale memories are used everywhere. From your iPhone to a supercomputer, every electronic device contains at least one such type. With coverage of current and prototypical technologies, Nanoscale Semiconductor Memories: Technology and Applications presents the latest research in the field of nanoscale memories technology in one place. It also covers a myriad of applications that nanoscale memories technology has enabled. The book begins with coverage of SRAM, addressing the design challenges as the technology scales, then provides design strategies to mitigate radiation induced upsets in SRAM. It discusses the current state-of-the-art DRAM technology and the need to develop high performance sense amplifier circuitry. The text then covers the novel concept of capacitorless 1T DRAM, termed as Advanced-RAM or A-RAM, and presents a discussion on quantum dot (QD) based flash memory. Building on this foundation, the coverage turns to STT-RAM, emphasizing scalable embedded STT-RAM, and the physics and engineering of magnetic domain wall "racetrack" memory. The book also discusses state-of-the-art modeling applied to phase change memory devices and includes an extensive review of RRAM, highlighting the physics of operation and analyzing different materials systems currently under investigation. The hunt is still on for universal memory that fits all the requirements of an "ideal memory" capable of high-density storage, low-power operation, unparalleled speed, high endurance, and low cost. Taking an interdisciplinary approach, this book bridges technological and application issues to provide the groundwork for developing custom designed memory systems.
