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. La présente invention concerne un échangeur de chaleur à calandre comprenant : un cylindre externe comportant une cavité ménagée en son sein de sorte que de l'eau de chauffage s'écoule le long de cette dernière ; une plaque de tube inférieure qui recouvre une ouverture à proximité d'une extrémité du cylindre externe ; une plaque de tube supérieure qui recouvre une ouverture à proximité de l'autre extrémité du cylindre externe, la plaque de tube supérieure fournissant un espace interne dans lequel est placée une source de chaleur ; une pluralité de conduits de fumée servant à guider du gaz de combustion de la plaque de tube supérieure vers l'extérieur de la plaque de tube inférieure ; et un diaphragme principal disposé dans un sens de référence entre la plaque de tube inférieure et la plaque de tube supérieure, une pluralité de trous traversants étant formés dans le diaphragme principal de sorte que les conduits de fumée le pénètrent, au moins certains des trous traversants constituant un trou traversant de grande largeur (trou unique) pénétré conjointement par au moins deux des conduits de fumée. 본 발명에 따른 관체형의 열교환기는, 난방수가 흐르는 중공이 마련되는 외통; 상기 외통의 일단 측의 개구를 덮는 하관판; 상기 외통의 타단 측의 개구를 덮되, 열원이 위치하는 내부 공간을 제공하는 상관판; 연소가스를 상기 상관판으로부터 상기 하관판의 외측으로 안내하는 복수 개의 연관들; 및 상기 하관판과 상기 상관판의 사이에서 기준방향을 가로지르게 배치되고, 상기 연관들이 관통하는 복수 개의 관통홀들이 형성되는 메인 격막을 포함하고, 상기 관통홀들 중 적어도 일부는, 상기 연관들 중 2개 이상의 연관들이 함께 관통하는 단일의 홀인 광폭 관통홀이다.
