FIELD: heat exchange technology.
SUBSTANCE: invention relates to the field of heat exchange technology and is intended for use in heat exchangers in the oil refining, chemical, petrochemical, timber, energy industries. The heat exchange section contains a transverse streamlined bundle of finned bimetallic tubes, tube sheets, bimetallic finned tubes are made with different diameters of the carrier tube, fins and fin heights, with the same fin spacing, tubes of large and small diameters are installed in sections with alternating staggered tubes of large and small diameters along the longitudinal and transverse axes of the tube bundle with a pitch of S1, S2 and adjacent surfaces of the fins with gaps.
EFFECT: increasing the energy efficiency of the heat exchange section.
