Principles of Enhanced Heat Transfer

Many changes have occurred in the field of enhanced heat transfer since the publication of the first edition in 1993. While the use of relatively complex geometries was initially limited by manufacturing processes, new manufacturing methods now allow the assemblage of many complex surface geometries. Some enhanced surfaces (e.g., boiling and condensing tubes) are in their fourth generation. As noted in Chapter 1, nearly all heat exchangers used in the air-conditioning and automotive industries are enhanced geometries. Further inroads are being seen in the electronic cooling, process, and power industries.
