Advanced designs of one of the simplest and reliable heat-exchange apparatuses for processing of various liquid and gaseous environments – heat exchangers "tube-in-tube" are considered. New designs in the majority a case eliminate the main defect of classical heat exchangers "tube-in-tube" – a small surface of a heat transfer. However increase in a heat exchange surface usually significantly complicates production and/or operation (including repair) heat exchangers. Classification of the heat exchange devices "tube-in-tube" is proposed: The following signs are the basis for classification: assembly level, quantity of streams in channels, the design material nature, degree of mobility of heat exchange tubes, existence of vortex generators in channels, a form of external and/or internal tubes. The critical analysis of the most characteristic designs of the heat exchangers "tube-in-tube" developed by domestic and foreign designers and inventors is made. Bibl. 17, Fig. 21.
