This book presents the ideas and industrialconcepts in compact heat exchanger technology that have been developed in thelast 10 years or so. Historically, the development and application of compactheat exchangers and their surfaces has taken place in a piecemeal fashion in anumber of rather unrelated areas, principally those of the automotive and primemover, aerospace, cryogenic and refrigeration sectors.
Much detailed technology, familiar in onesector, progressed only slowly over the boundary into another sector. Thiscompartmentalisation was a feature both of the user industries themselves, andalso of the supplier, or manufacturing industries. These barriers are nowbreaking down, with valuable cross-fertilisation taking place.
One of the industrial sectors that is waking upto the challenges of compact heat exchangers is that broadly defined as theprocess sector. If there is a bias in the book, it is towards this sector.Here, in many cases, the technical challenges are severe, since high pressuresand temperatures are often involved, and working fluids can be corrosive,reactive or toxic. The opportunities, however, are correspondingly high, sincecompacts can offer a combination of lower capital or installed cost, lowertemperature differences (and hence running costs), and lower inventory. In somecases they give the opportunity for a radical re-think of the process design,by the introduction of process intensification (PI) concepts such as combiningprocess elements in one unit. An example of this is reaction and heat exchange,which offers, among other advantages, significantly lower by-productproduction.
To stimulate future research, the authorincludes coverage of hitherto neglected approaches, such as that of the SecondLaw (of Thermodynamics), pioneered by Bejan and co- workers. The justificationfor this is that there is increasing interest in life-cycle and sustainableapproaches to industrial activity as a whole, often involving exergy (SecondLaw) analysis. Heat exchangers, being fundamental components of energy andprocess systems, are both savers and spenders of exergy, according tointerpretation
