FIELD: heat power engineering.

SUBSTANCE: heat exchange apparatus comprises housing, collectors with branch pipes for supplying and discharging first heat-transfer agent, branch pipes for input and output of the second heat-transfer agent from the housing and heat exchange pipe bundle with pipe plate, and structural members interposed between pipes to cause the second heat-transfer agent to flow around the pipe bundle in the transverse direction. The members are made of screw baffles provided with openings for the pipe bundle. The first heat-transfer agent flows in the pipe bundle. The heat exchange apparatus has two unmovable pipe plates or one unmovable pipe plate and one floating head, or one unmovable pipe plate and U-shaped pipes. The screw baffle is multirow.
