FIELD: heat exchange.
SUBSTANCE: invention relates to heat exchange equipment and can be used in shell-and-tube heat exchangers. In a shell-and-tube heat exchanger consisting of a tube and an tube space, the tube and tube spaces are organized by means of longitudinal and transverse partitions, provides for several passes of hot or cold flow of processed medium with cylindrical smooth tubes, number and diameter of which are determined by properties of passing flow, for example, density or viscosity, and vary from stroke to stroke, at least one of the strokes is made with variable pitch of transverse partitions.
EFFECT: increased compactness and service life of heat exchanger by arrangement of variable cross-sections of channels (passages) of processed medium flow passage.
