Abstract

Die Erfindung betrifft einen Plattenwärmetauscher mit mehreren übereinander gestapelten Trennwänden (10), die abwechselnd jeweils einen ersten und einen zweiten Durchflussraum (12, 14) für ein erstes, bzw. zweites Medium aufspannen, wobei in zumindest einem Durchflussraum (12, 14) zumindest ein vorzugsweise aus Blech bestehender Turbulenzerzeuger (16) angeordnet ist, welcher aus einer Platte mit mehreren nebeneinander angeordneten bandartigen Reihen (18, 20) alternierend hintereinander folgender Erhebungen (22) und Senken (24) besteht, welche über Stege (26, 28) miteinander verbunden sind, wobei die Erhebungen (22) und Senken (24) jeder Reihe (18, 20) in Bezug auf jede unmittelbar benachbarte Reihe (20; 18) versetzt sind, und wobei jede der Reihen (18, 20) zumindest einen Übertrittsbereich (30, 32) für das Medium zur unmittelbar angrenzenden Reihe (20; 18) aufweist, so dass die Senken (24) jeder Reihe (18, 20) mit unmittelbar angrenzenden Erhebungen (22) zumindest einer unmittelbar benachbarten Reihe (20, 18) in Strömungsverbindung stehen. Um auf möglichst einfache Weise eine hohe Wärmeübertragungsleistung zu erreichen, ist vorgesehen, dass die Stege (26, 28) jeder Reihe (18, 20) zueinander im Wesentlichen parallel angeordnet und gleichsinnig in Bezug auf die Trennwände (10) geneigt ausgebildet sind, wobei zwischen einer Trennwand (10) und den Stegen (26, 28) jeweils ein spitzer Winkel (α) aufgespannt ist.

The invention relates to a plate heat exchanger having a plurality of partition walls (10) stacked one above the other and alternately defining a first and a second flow space (12, 14) for a first or second medium, at least one in at least one flow space (12, 14) preferably consisting of sheet metal turbulence generator (16) is arranged, which consists of a plate with a plurality of juxtaposed band-like rows (18, 20) alternately successively following surveys (22) and depressions (24), which via webs (26, 28) connected to each other with the elevations (22) and depressions (24) of each row (18, 20) being offset with respect to each immediately adjacent row (20; 18), and wherein each of the rows (18, 20) comprises at least one transition area (30 , 32) for the medium to the immediately adjacent row (20; 18), so that the depressions (24) of each row (18, 20) with immediately adjacent elevations (22) at least one immediately bar adjacent row (20, 18) are in fluid communication. In order to achieve a high heat transfer performance in the simplest possible way, it is provided that the webs (26, 28) of each row (18, 20) arranged substantially parallel to each other and inclined in the same direction with respect to the partitions (10), wherein between a partition wall (10) and the webs (26, 28) in each case an acute angle (α) is clamped.
