SHELL AND TUBE HEAT EXCHANGER, PACKAGE OF PIPES FOR SHELL AND TUBE HEAT EXCHANGER, COMPONENT OF THE PIPE OF PIPES, APPLICATION OF SHELL AND TUBE HEAT EXCHANGER (OPTIONS)

摘要

The invention relates to a shell and tube heat exchanger (1) in which a tube bundle (2) consisting of a plurality of tubes (20, 22, 27) having at least one tube bottom (25; 26) is arranged in a shell space (3), in order to be able to increase the heat exchanger area without having to enlarge the total diameter of a shell and tube heat exchanger. The shell and tube heat exchanger (1) is delimited to the outside by a shell surface (31) and has a longitudinal axis (33) extending centrally in the shell space, around which an inner channel (21), which is free of tubes, is designed, and wherein an outer channel (23), which is free of tubes, is designed on the inside, adjacent to the shell surface (31), wherein the tube bundle (2) comprises at least two tube bundle components (50, 51, 2, 53, 54) between the inner channel (21) and the outer channel (23), which differ in the number of tubes per area and/or in the outside diameter of the tubes and/or in the spacing of the tubes.
