This book is the first in English being entirely dedicated to
Miniature Joule-Thomson Cryocooling. The category of Joule-Thomson
(JT) cryocoolers takes us back to the roots of cryogenics, in 1895,
with figures like Linde and Hampson. The "cold finger" of these
cryocoolers is compact, lacks moving parts, and sustains a large
heat flux extraction at a steady temperature. Potentially, they
cool down unbeatably fast. For example, cooling to below 100 K
(minus 173 Celsius) might be accomplished within only a few seconds
by liquefying argon. A level of about 120 K can be reached almost
instantly with krypton. Indeed, the species of coolant plays a
central role dictating the size, the intensity and the level of
cryocooling. It is the JT effect that drives these cryocoolers and
reflects the deviation of the "real" gas from the ideal gas
properties. The nine chapters of the book are arranged in five
parts. *The Common Principle of Cyrocoolers shared across the broad
variety of cryocooler types *Theoretical Aspects: the JT effect and
its inversion, cooling potential of coolants, the liquefaction
process, sizing of heat exchangers, level of pressurization,
discharge of pressure vessels * Practical Aspects: modes of
operation (fast cooldown, continuous, multi-staging, hybrid
cryocoolers), pressure sources, configuration, construction and
technologies, flow adjustment, MEMS, open and closed cycle,
cooldown process and similarity, transient behavior * Mixed Coolant
cryocooling: theory, practice and applications * Special Topics:
real gas choked flow rates, gas purity, clog formation, optimal
fixed orifice, modeling, cryosurgical devices, warming by the
inverse JT effect The theoretical aspects may be of interest not
only to those working with cryocoolers but also for others with a
general interest in "real" gas thermodynamics, such as, for
example, the inversion of the JT effect in its differential and
integral forms, and the exceptional behavior of the quantum gases.
A detailed list of references for each chapter comprises a broad
literature survey. It consists of more than 1,200 relevant
publications and 450 related patents. The systematically organized
content, arranged under a thorough hierarchy of headings, supported
by 227 figures and 41 tables, and accompanied by various
chronological notes of evolution, enables readers a friendly
interaction with the book. Dr. Ben-Zion Maytal is a Senior
Researcher at Rafael-Advanced Defense Systems, Ltd., and an Adjunct
Senior Teaching Fellow at the Technion-Israel Institute of
Technology, Haifa, Israel. Prof. John M. Pfotenhauer holds a joint
appointment in the Departments of Mechanical Engineering and
Engineering Physics at the University of Wisconsin - Madison.
