ABSTRACT A detailed overview of heat pipes is presented in this paper, including a historical perspective, principles of operations, types of heat pipes, heat pipe performance characteristics, heat pipe limitations, heat pipe frozen startup and shutdown, heat pipe analysis and simulations, and various applications of heat pipes. Over the last several decades, several factors have contributed to a major transformation in heat pipe science and technology . The first major contribution was the development and advances of new heat pipes, such as loop heat pipes, micro and miniature heat pipes, and pulsating heat pipes. In addition, there are now many new commercial applications that have helped contribute to the recent interest in heat pipes, especially related to the fields of electronic cooling and energy. For example, several million heat pipes are now manufactured each month since all modern laptops use heat pipes for CPU cooling. Numerical modeling, analysis, and experimental simulation of heat pipes have also significantly progressed due to a much greater understanding of various physical phenomena in heat pipes, as well as advances in computational and experimental methodologies. Keywords: heat pipes, performance characteristics,

  • Micro-Columnated Loop Heat Pipe: the Future of Electronic Substrates
    Micro-Columnated Loop Heat Pipe: The Future of Electronic Substrates by Navdeep Singh Dhillon A dissertation submitted in partial satisfaction of the requirements for the degree of Doctor of Philosophy in Engineering – Mechanical Engineering in the GRADUATE DIVISION of the UNIVERSITY OF CALIFORNIA, BERKELEY Committee in charge: Professor Albert P. Pisano, Chair Professor Liwei Lin Professor Omer Savas¸ Professor Ali Javey Spring 2012 Micro-Columnated Loop Heat Pipe: The Future of Electronic Substrates Copyright 2012 by Navdeep Singh Dhillon 1 Abstract Micro-Columnated Loop Heat Pipe: The Future of Electronic Substrates by Navdeep Singh Dhillon Doctor of Philosophy in Engineering – Mechanical Engineering University of California, Berkeley Professor Albert P. Pisano, Chair The modern world is run by semiconductor-based electronic systems. Due to contin- uous improvements in semiconductor device fabrication, there is a clear trend in the market towards the development of electronic devices and components that not only deliver enhanced computing power, but are also more compact. Thermal manage- ment has emerged as the primary challenge in this scenario where heat flux dissipa- tion of electronic chips is increasing exponentially, but conventional cooling solutions such as conduction and convection are no longer feasible. To keep device junction temperatures within the safe operating limit, there is an urgent requirement for ultra- high-conductivity thermal substrates that not only absorb and transport large heat fluxes, but can also provide localized cooling to thermal hotspots. This dissertation describes the design, modeling, and fabrication of a phase change- based, planar, ultra-thin, passive thermal transport system that is inspired by the concept of loop heat pipes and capillary pumped loops.

The workshop provided a venue for researchers, educators and policy-makers to identify frontier challenges and asso- ciated opportunities in heat and mass transfer. Approximately 300 invited participants from academia, business and government from the US and abroad attended. Based upon the final recommendations on the topical matter of the workshop, several trends become apparent. A strong interest in sustainable energy is evident. A continued need to understand the coupling between broad length (and time) scales persists, but the emerging need to better understand transport phenomena at the macro/mega scale has evolved. The need to develop new metrology techniques to collect and archive reliable property data persists. Societal sustainability received major atten- tion in two of the reports. Matters involving innovation, entrepreneurship, and globalization of the engineering profession have emerged, and the responsibility to improve the technical literacy of the public-at-large is discussed.
