Cryogenic engineering (cryogenics) is the production, preservation, and use or application of the cold. Cryogenic Heat Management presents a comprehensive introduction into designing systems to deal with heat – effective management of the cold, exploring the directing (or redirecting), promoting or inhibiting this flow of heat in a practical way. It provides a description of the necessary theory, design methodology and advanced demonstrations (thermodynamics, heat transfer, thermal insulation, fluid mechanics) for many frequently occurring situations in low temperature apparatus. This includes systems that are widely used such as superconducting magnets for magnetic resonance imaging (MRI), high energy physics, fusion, tokamak and free electron laser systems; space launch and exploration; energy and transportation use of liquid hydrogen; as well as potential future applications of cryo-life-sciences and chemical industries.

It assumes that the reader has had an undergraduate understanding of thermodynamics, heat transfer, and fluid mechanics, in addition to the mechanics of materials, material science, and physical chemistry. It will be a valuable guide for those researching, teaching or working with low temperature or cryogenic systems, in addition to postgraduates studying the topic.

Key features:

  • Presents simplified but useful and practical equations that can be applied in estimating performance and design of energy efficient systems in low temperature or cryogenics.
  • Contains practical approaches and advanced design materials for insulation, shield/anchor, cryogen vessel/pipe, calorimeter, cryogenic heat switch, cryostat, current lead and RF coupler.
  • Provides a comprehensive introduction to the necessary theory and models needed to solutions for common difficulties and illustrates the engineering examples with about 200 figures.
