Description
Die Erfindung betrifft eine Wärmetauscher-Einrichtung mit Wärmetauscher-Rohren und blechförmigen, Bohrungen aufweisenden Lamellen, deren Rand aus den Seitenkanten eines länglichen Bandes und aus das Band schräg neben den Bohrungen durchschneidenden, parallelen Grundkanten besteht, wobei sich die Wärmetauscher-Rohre durch die Bohrungen hindurch erstrecken, deren Durchmesser (da) dem Aussendurchmesser der Wärmetauscher-Rohre entspricht, und die in einem rechtwinkeligen Gitter angeordnet sind, dessen Längsgitterlinien zu den Seitenkanten des Randes parallel und dessen Quergitterlinien zu den Seitenkanten des Randes senkrecht verlaufen, wobei die Gitterlinien in den beiden zueinander senkrechten Gitterrichtungen konstante Teilungen S₁, S₂ aufweisen, und wobei benachbarte Quergitterlinien um eine halbe Teilung (s₁/2) gegeneinander versetzt sind.The invention relates to a heat exchanger device with heat exchanger tubes and sheet-shaped, bores having fins, the edge of which consists of the side edges of an elongated band and the band obliquely next to the bores intersecting, parallel base edges, the heat exchanger tubes passing through the bores extend, the diameter (da) of which corresponds to the outside diameter of the heat exchanger tubes, and which are arranged in a right-angled grid whose longitudinal grid lines are parallel to the side edges of the edge and whose cross grid lines are perpendicular to the side edges of the edge, the grid lines in the two relative to one another perpendicular grating directions have constant divisions S₁, S₂, and adjacent cross grating lines are offset by half a division (s₁ / 2).
Derartige Wärmetauscher-Einrichtungen mit blechförmigen Lamellen, deren Rand aus den Seitenkanten eines Bandes und aus das Rechteck schräg neben den Bohrungen durchschneidenden, zueinander parallelen Grundkanten besteht, sind intern bei der Anmelderin bekannt. Bei der bekannten Wärmetauscher-Einrichtung ist der Winkel, den jede Grundkante mit dem Längsrand des Bandes einschliesst, durch den arc tg des Quotienten der Teilung der Quer gitterlinien zur Teilung der Längsgitterlinien gegeben. Die das längliche Band schräg neben den Bohrungen durchschneidenden Grundkanten dienen dabei dazu, die Gesamthöhe des Wärmetauschers, die senkreckt zu den das Band schräg neben den Bohrungen durchschneidenden Grundkanten gemessen wird, zu reduzieren. Bei einer solchen Wärmetauscher-Einrichtung geht die versetzte Anordnung der Wärmetauscher-Rohre durch die Anordnung der das längliche Band schräg neben den Bohrungen durchschneidenden Grundkanten in eine fluchtende Anordung über, wodurch sich eine Verringerung des Wärmew irkungsgrades der Wärmetauscher-Einrichtung ergibt.Such heat exchanger devices with sheet-like fins, the edge of which consists of the side edges of a strip and of the rectangle obliquely adjacent to the bores which cut through and parallel basic edges, are known internally to the applicant. In the known heat exchanger device the angle that each base edge encloses with the longitudinal edge of the belt is given by the arc tg of the quotient of the division of the transverse grating lines to the division of the longitudinal grating lines. The basic edges that cut through the elongated band at an angle next to the holes serve to reduce the overall height of the heat exchanger, which is measured to the basic edges that cut through the band at an angle next to the holes. In such a heat exchanger device, the staggered arrangement of the heat exchanger tubes passes through the arrangement of the base edges which cut through the oblong band obliquely next to the bores into an aligned arrangement, which results in a reduction in the heat efficiency of the heat exchanger device.
Deshalb liegt der vorliegenden Erfindung die Aufgabe zugrunde, eine Wärmetauscher-Einrichtung der eingangs genannten Art zu schaffen, bei der durch eine geeignete Wahl der Schnitt durch das längliche Band derart möglich ist, dass die Gesamthöhe der Wärmetauscher-Einrichtung weiter reduziert ist und gleichzeitig benachbarte Wärmetauscher-Rohre in vorteilhafter Weise nicht miteinander fluchten.Therefore, the present invention has for its object to provide a heat exchanger device of the type mentioned, in which the cut through the elongated band is possible by a suitable choice such that the overall height of the heat exchanger device is further reduced and at the same time adjacent heat exchangers Advantageously, pipes are not aligned.
Diese Aufgabe wird erfindungsgemäss dadurch gelöst, dass die Grundkante mit der Seitenkante des Randes einen Winkel A einschliesst, der durch die Formel
Durch den wiederkehrenden Schnitt durch das Band entlang den Grundkanten entsprechend den zuletzt genannten Formeln wird der Vorteil erzielt, dass die Wärmetauscher-Rohre in Anströmrichtung gesehen nicht miteinander fluchten, sondern gegeneinander versetzt sind. Dadurch ergibt sich ein vergleichsweise hoher thermischer Wirkungsgrad der Wärmetauscher-Einrichtung. Ein erheblicher Vorteil der erfindungsgemässen Wärmetauscher-Einrichtung besteht darin, dass seine gesamte Einbauhöhe über der zum Rand schräg verlaufenden Grundkante bei einem entsprechenden Wärmewirkungsgrad kleiner ist als bei einer bekannten Wärmetauscher-Einrichtung der gattungsgemässen Art.The recurring cut through the strip along the base edges in accordance with the last-mentioned formulas has the advantage that the heat exchanger tubes are not aligned with one another in the flow direction, but are offset from one another. This results in a comparatively high thermal efficiency of the heat exchanger device. A significant advantage of the heat exchanger device according to the invention is that its overall installation height above the base edge, which is inclined to the edge, is smaller with a corresponding thermal efficiency than with a known heat exchanger device of the generic type.
Weitere Einzelheiten ergeben sich aus der nachfolgenden Beschreibung einer in der Zeichnung dargestellten erfindungsgemässen Wärmetauscher-Einrichtung.Further details emerge from the following description of a heat exchanger device according to the invention shown in the drawing.

Wie aus Figur 2 ersichtlich ist, erstrecken sich die Wärmetauscher-Rohre 20 durch die Bohrungen 12 der blechförmigen Lamellen 10 hindurch, wobei in dieser Figur nur ein Wärmetauscher-Rohr 20 abschnittweise dargestellt ist. Der lichte Innendurchmesser der Bohrungen 12 in den blechförmigen Lamellen 10 entspricht dem Aussendurchmesser der Wärmetauscher-Rohre 20. Die Bohrungen 12 sind in der blechförmigen Lamelle 10 in einem rechtwinkeligen Gitter angeordnet, das in Figur 1 durch strichpunktierten Linien und angedeutet ist. Die Längsgitterlinien 22 bzw. die Quergitterlinien 24 weisen konstante Teilungen s₂ bzw. s₁ auf, wobei benachbarte Quergitterlinien 24 um eine halbe Teilung s₁/2 gegeneinander versetzt sind.As can be seen from FIG. 2, the
Bei der erfindungsgemässen Wärmetauscher-Einrichtung schliesst die das Band schräg durchschneidende Grundkante 18 mit der länglichen Seitenkante 16 einen Winkel A ein, der durch die Formel
Die Schnittlinie liegt innerhalb eines streifenförmigen Bereiches 26, der in Figur 1 kreuzweise schraffiert angedeutet ist und der beispielsweise eine Breite c ≧ 2 mm aufweist. Diese Breite c ist durch die Breite des Schneidwerkzeuges vorgegeben, mit dem das Band durchschnitten werden soll. Bei einem schmäleren Werkzeug kann c auch bei 1 mm und darunter liegen. Die Breite c wird durch die Abmessungen der Bohrungen12 und durch deren Anordnung in einem rechtwinkeligen Gitter bestimmt; sie ist durch die Formel
Wie aus Figur 2 deutlich ersichtlich ist, weisen die Bohrungen 12 in der Lamelle 10 je einen Kragen 28 auf, der aus dem Material der blechförmigen Lamelle 10 durch eine Bördelung hergestellt wird. Jeder Kragen 28 steht von der Lamelle 10 senkrecht weg, wobei alle Kragen 28 von der Lamelle 10 in die gleiche Richtung weisen. Wenn die Lamellen 10 Bohrungen 12 mit Kragen 28 aufweisen, so besteht der Durchmesser da der Bohrungen 12 aus dem lichten Innendurchmesser der Bohrung 12 und der doppelten Wanddicke des die Bohrung 12 umgebenden Kragens 28 (siehe Figur 2).As can be clearly seen from FIG. 2, the
Mit "H" ist in Figur 1 die Einbauhöhe der erfindungsgemässen Wärmetauscher-Einrichtung bezeichnet, die in vorteilhafter Weise bei quasi der Anzahl einer bekannten Wärmetauscher-Einrichtung entsprechender Anzahl Wärmetauscher-Rohre 20 kleiner ist als die Einbauhöhe einer bekannten Wärmetauscher-Einrichtung der gattungsgemässen Art. Durch die nebeneinander parallel verlaufenden Pfeile "B" ist die Anströmrichtung eines Fluides bezeichnet, das seine Energie mit dem die Wärmetauscher-Rohre 20 durchströmenden Fluid austauscht."H" in FIG. 1 denotes the installation height of the heat exchanger device according to the invention, which is advantageously smaller than the installation height of a known heat exchanger device of the generic type with a number of
