Zusammenfassung: | To improve heat exchange efficiency of a shell-and-plate type heat exchanger.SOLUTION: A shell-and-plate type heat exchanger (1) comprises a shell (10) for forming an internal space (15), and a plate laminated body (20) comprising a plurality of heat transfer plates (21) laminated and joined to each other, and housed in the internal space (15), and condenses a refrigerant having flowed into the internal space (15). Refrigerant flow passages (24) communicating with the internal space (15), and through which the refrigerant flows, and heat medium flow passages (25) isolated from the internal space (15), and through which a heat medium flows are alternately arranged between the adjacent plates (21). Meandering parts (28, 29, and 31) for meandering the refrigerant condensed on respective surfaces of the plurality of heat transfer plates (21) are provided in at least a lower part of the plate laminated body (20).SELECTED DRAWING: Figure 2
【課題】シェルアンドプレート式熱交換器の熱交換効率を向上させる【解決手段】シェルアンドプレート式熱交換器(1)は、内部空間(15)を形成するシェル(10)と、重ね合わされて互いに接合された複数の伝熱プレート(21)を有して内部空間(15)に収容されるプレート積層体(20)とを備え、内部空間(15)へ流入した冷媒を凝縮させる。隣接するプレート(21)同士の間に、内部空間(15)に連通して冷媒が流れる冷媒流路(24)と、内部空間(15)から遮断されて熱媒体が流れる熱媒体流路(25)とが交互に配置される。プレート積層体(20)の少なくとも下部に、複数の伝熱プレート(21)のそれぞれの表面上で凝縮した冷媒を蛇行させる蛇行部(28,29,31)が設けられる。【選択図】図2 |
