    摘要： A heat exchanger (10) includes a first flat pipe (1) having a plurality of through-holes through which a high-temperature fluid flows, a second flat pipe (2) having a plurality of through-holes (21) through which a low-temperature fluid flows, a first inlet header (3) having a tubular shape and connected to one end of the first flat pipe (1), a first outlet header (4) having a tubular shape and connected to other end of the first flat pipe (1), a second inlet header (5) having a tubular shape and connected to one end of the second flat pipe (2), and a second outlet header (6) having a tubular shape and connected to other end of the second flat pipe (2). The first flat pipe (1) and the second flat pipe (2) are stacked such that flat surfaces thereof are in contact with each other. The low-temperature fluid flowing into the through-holes (21) in the second flat pipe (2) from the second inlet header (5) is a fluid in a two-phase gas-liquid state. The low-temperature fluid flows into the through-holes (21) in the second flat pipe (2) from the second inlet header (5) in a substantially horizontal direction or in an upward direction relative to the substantially horizontal direction.

    摘要： Ein Rohrwärmetauscher umfasst mindestens ein durch selektives Laserschmelzen in einem Stück ausgebildetes Rohrwärmetauschermodul (1) mit einem bis auf die Zuführungsanschlüsse (6, 7) und Auslassanschlüsse geschlossenen Gehäuse (2) zur Durchleitung des ersten Mediums und einer im Innern des Gehäuses auf engem Raum ausgebildeten Rohrleitung (10) zur Durchleitung des zweiten Mediums. Die Rohrleitung ist zur Erzielung einer großen Wärmeübertragungsfläche vorteilhafterweise in mehreren Ebenen jeweils mäanderförmig im Gehäuse (2) verlegt. Der durch Laserschmelzen erzielte einstückige Aufbau des Rohrwärmetauschers erlaubt eine freie Gestaltung des Gehäuses und der in diesem verlaufenden Rohrleitung, so dass die Druck- und Reibungsverluste minimiert werden können und ein kompakt ausgebildeter Rohrwärmetauscher mit hoher Wärmeübertragungseffizienz bereitgestellt werden kann. Zur Erhöhung der Wärmeübertragungskapazität können zwei oder mehrere Rohrwärmetauschermodule fest miteinander verbunden werden.

    摘要： The invention is a heat exchanger (1; 10), particularly suited to be used in condensation boilers, comprising: a tubular jacket (2) that internally delimits a first duct (3) developed between an inlet section (3a) and an outlet section (3b) that define an outflow direction (F) for a first fluid; a second duct (4; 11) arranged in thermal contact with the tubular jacket (2) and developed mainly outside the first duct (3) between an inlet mouth (4a; 11a) and an outlet mouth (4b; 11 b) for a second fluid; heat exchange elements (5, 5') projecting from the tubular jacket (2) towards the inside of the first duct (3); a thin body (7) arranged in the first duct (3) parallel to the outflow direction (F) and in thermal contact with one or more heat exchange elements (5).

    摘要： There is provided a heat exchanger having high heat exchange efficiency in comparison with conventional heat exchange elements, heat exchangers, and the like and realizing miniaturization, weight saving, and cost reduction and a production method thereof. In a heat exchange element 1, first fluid circulation portions 5 having a honeycomb structure having a plurality of cells separated by ceramic partition walls 4, extending through in an axial direction from one end face 2 to the other end face 2, and allowing a heated medium as a first fluid to flow therethrough and second fluid circulation portions 6 being separated by ceramic partition walls 4, extending in the direction perpendicular to the axial direction, allowing a second fluid to flow therethrough, transferring heat to a medium to be heated as the second fluid are alternately formed as a unit. The cells 3 on the first fluid circulation portion 5 side are smaller than the cells 3 on the second fluid circulation portion 6 side, and the partition walls have a density of 0.5 to 5 g/cm 3 and a thermal conductivity of 10 to 300 W/mK.
