Abstract
A shell-and-tube heat exchanger according to the present invention comprises: an outer barrel having a cavity provided therein such that heating water flows along the same; a lower tube plate that covers an opening near one end of the outer barrel; an upper tube plate that covers an opening near the other end of the outer barrel, the upper tube plate providing an inner space in which a heat source is positioned; a plurality of flues for guiding combustion gas from the upper tube plate to the outside of the lower tube plate; and a main diaphragm arranged across a reference direction between the lower tube plate and the upper tube plate, a plurality of through-holes being formed in the main diaphragm such that the flues penetrate the same, wherein at least some of the through-holes constitute a large-width through-hole (single hole) that at least two of the flues penetrate together.
