Beschreibung

Complete introduction to the field of thermoelectrics, covering materials, applications, recent developments, and more, with end-of-chapter problems included throughout

Thermoelectrics provides an introduction to the fundamental theories in the fast developing and interdisciplinary field of thermoelectrics. The topics covered are in sync with contemporary technology advancement happenings within the TEC/TEG electronics cooling community and include discussion of challenges and concerns surrounding practical applications.

The first section covers thermoelectric generators and coolers (refrigerators) before examining optimal design with dimensional analysis. A number of applications are considered, including solar thermoelectric generators, thermoelectric air conditioners and refrigerators, thermoelectric coolers for electronic devices, thermoelectric compact heat exchangers, and biomedical thermoelectric energy harvesting systems. The second section focuses on materials and covers the physics of electrons and phonons, theoretical modeling of thermoelectric transport properties, thermoelectric materials, and nanostructures.

In this Second Edition, many new examples and end-of-chapter problems have been added. New results from the theories have been added in certain chapters, along with new design charts and many examples showing how to use the charts. A companion website hosts solution manuals and appendices.

Sample topics covered in Thermoelectrics include:

• Thermoelectric effects, including the Seebeck, Peltier, and Thomson effects as well as Thomson/Kelvin relationships
• Performance, maximum, abnormal parameters for thermoelectric modules as well as effective material properties
• Thermal and electrical contact resistances for micro and macro devices, with information on modeling and validation
• Thermoelectric transport properties, covering Seebeck coefficient, electrical conductivity, lattice and electronic thermal conductivities
• Low-dimensional nanostructures, covering quantum wells, wires, and dots and supporting proof-of-principle studies

Thermoelectrics is an ideal resource on the fundamentals of the subject for professionals in the electronics cooling industry, solid state physicists, and materials scientists and engineers. It is also a valuable reference for early career scientists and undergraduate and graduate students in related programs of study.

Preface to the Second Edition

The second edition of this book continues the goal of serving as a senior or graduate textbook on thermoelectrics with engineering applications. In this edition, I have made two key improvements: first, Chapter 4 on optimal system design has been substantially extended to further configurations, including radiation and heat flux. Second, I have made many example problems and homework problems throughout the chapters for student exercises. The extended material includes theories and new characteristic design curves for thermoelectric systems, which are very important for system designers. I believe this new and extended material to be concrete, as it is based on thought experiments, indirect justifications, and careful efforts to avoid any mistakes. Regardless, corrections and suggestions are gratefully received and may be addressed to the author by email to [email protected].

Preface to the First Edition

This book is written as a senior undergraduate or a first-year graduate textbook. Thermoelectrics is the study of energy conversion between thermal energy and electrical energy in solid-state matters. It is an emerging field with comprehensive applications, such as exhaust waste heat recovery, solar energy conversion, automotive air conditioning, deep-space exploration, electronic control and cooling, and medical instrumentation. Thermoelectrics involves multiple interdisciplinary fields: physics, chemistry, electronics, material sciences, nanotechnology, and mechanical engineering. Much of the theory and materials are still under development, mostly on the materials but minimally on the design. The author has taught thermoelectrics courses for the past years, believing that a textbook is necessary to put a spur on the development. However, the author experienced considerable difficulties, partly because of the need to make a selection from the existing material, and partly because the customary exposition of many topics to be included does not possess the necessary physical clarity. It is realized that the author’s own treatment still has many defects, which are desirable to correct in future edition. The author has an open mind and appreciation on any comments and defects that may be found in the book. Typically, design and materials are considered separate fields. However, in thermoelectrics, these two fields are interrelated, particularly when the size is small and the variation of temperature is large. Hence, this book includes the design and materials for future vigorous engagement.

This book comprises two parts: design (Chapters 1–8) and materials (Chapters 9–16). The design part covers theoretical formulation, optimal design, experimental verification, modeling, and applications. The materials part cover the physics of thermoelectrics for electrons and phonons, experimental verification, modeling, nanostructures, and thermoelectric materials. Each part can be used for a semester period (usually an introductory session on the subtle phenomena of thermoelectrics given in the beginning of class) or both parts can be covered in a semester period by skimming some topics for students or readers already familiar with the topics. The author made significant efforts to manage the content in Part I with a fundamental heat transfer course as a prerequisite and the content in Part II with an introductory materials science course. The author also attempted to provide detailed derivations of formulas so students or readers can have a conviction on studying thermoelectrics and also to provide detailed calculations so that they can even build their own mathematical programs. Hence, many exercise problems at the end of each chapter require students or readers to provide Mathcad programs to solve the problems.

I acknowledge the suggestions and help provided by undergraduate and graduate students throughout classes and research projects. Special thanks are given to Dr. Alaa Attar, now a professor at King Abdul-Aziz University, Saudi Arabia, for his help in measurements and computations. I am also indebted to Professor Emeritus Herman Merte, Jr., for his lifetime inspiration in the preparation of this book. I am very grateful to Professor Emeritus Stanley L. Rajnak, who read the manuscript and made many useful comments.
