Abstract

The finned heat exchanger consists of fins which are turned to and fro between the coverplates. The sheet metal of the fins is profiled in such a way that upon superimposition a structure is produced which resembles a chessboard and has a very high heat exchanging area per unit of volume. The profile can have the following profile shapes in this case: rectangular profile, trapezoidal profile, excessive trapezoidal profile (with acute-angled trapezoidal cones), or similar profile shapes which, upon superimposition, form parallel channels (ducts) through which the medium (gas) flows. In this case, the profiled metal sheet can have an inherent structure such that transverse to the direction of flow the channel wall is corrugated, laterally offset or otherwise structured in such a way that turbulence or a spiral flow is produced. The overall result on the gas side is an increase in the heat exchange and an enlargement of the heat exchange area (compactness).

Description

Die profilierte und evl. in sich noch strukturierte Rippenform läßt sich in allen Rippenwärmetauschern und an berippten Plattenwärmetauschern zur Raumheizung anwenden. Die bekannten Rippenformen weisen z. B. im PS-DE 3119628 C2 oder PS-DE 3345558 CL oder PS-DE 3606253 A1 jeweils einen hin- und hergewendeten Blechstreifen als Rippe auf, wobei allerdings die nebeneinanderbefindlichen Rippen das Medium so umhüllen, daß ein flacher Kanal entsteht, in dem nur zum Rippenblech hin ein Wärmetransport stattfindet, nicht aber parallel zum Rippenblech. Die Vorzüge eines Rippenwärmetauschers sind aber gerade darin zu sehen, daß auf der Luftseite der Wärmeübergang intensiviert wird. Bedingt dadurch, daß bei Flüssig-Luft-Wärmetauschern auf der Luftseite medienbedingt nur ein wesentlich geringerer Wärmeübergang möglich ist, sollte die Wärmetauschfläche auf der Luftseite (Wärmetauschrippen) so gestaltet werden, daß auf engem Raum eine möglichst große Wärmetauschfläche untergebracht wird, die im günstigsten Fall gleichzeitig in sich strukturiert sein sollte, um die Wärmeübergangszahl auf der Luftseite zu erhöhen. Dieses Ziel läßt sich mit einem profilierten Blech erzeugen, bei dessen Profilform nicht wie bisher parallele Rippen entstehen, sondern mit einer rechteckähnlichen Profilstruktur durch das Hin- und Herwenden und Übereinenderliegen eine schachbrettähnliche Struktur entsteht. Dabei kann zusätzlich das Profil in sich derart strukturiert sein, daß quer zur Strömungsrichtung gesehen die Kanalwandung gewellt oder andersartig strukturiert ist, so daß Turbulenzen oder eine Spiralströmung entstehen.The profiled and possibly rib structure still structured in itself can be in all Use finned heat exchangers and on finned plate heat exchangers for space heating. The known rib shapes have z. B. in PS-DE 3119628 C2 or PS-DE 3345558 CL or PS-DE 3606253 A1 each have a sheet metal strip turned back and forth as a rib, however, the adjacent ribs envelop the medium so that a a flat channel is created, in which heat is only transported to the ribbed plate, not but parallel to the ribbed sheet. But the advantages of a finned heat exchanger are straight to see that the heat transfer is intensified on the air side. Because that in liquid-air heat exchangers on the air side due to the media only one essential Less heat transfer is possible, the heat exchange surface should be on the air side (Heat exchange fins) are designed so that the largest possible in a confined space Heat exchange surface is housed, which in the best case at the same time in itself should be structured to increase the heat transfer coefficient on the air side. That goal can be created with a profiled sheet, with its profile shape not as before parallel ribs are created, but with a rectangular profile structure through the Turning back and forth and lying one on top of the other creates a checkerboard-like structure. Here the profile can also be structured in such a way that transverse to the direction of flow seen the channel wall is corrugated or structured differently, so that turbulence or a spiral flow arise.

Das rechteckähnliche Profil kann bestehen aus:The rectangular profile can consist of:

  • - Rechtecken (Fig. 1)- Rectangles ( Fig. 1)
  • - Trapezformen (Fig. 2) die teilweise ineinanderrutschen können- Trapezoidal shapes ( Fig. 2) that can sometimes slide into each other
  • - überhöhter Trapezkegeln (Fig. 3) dessen Winkel spitzwinklig sind.- excessive trapezoidal cone ( Fig. 3) whose angles are acute.

Durch die erfindungsgemäße Rippenprofilierung wird die am Wärmetausch aktiv beteiligte Rippenfläche um ca. 60% erhöht. Damit kann bei gleichen äußeren Abmessungen eines Rippenwärmetauschers die Wärmetauschfläche und damit die Kompaktheit und Wärmetauschleistung wesentlich erhöht werden, oder bei Beinhaltung einer geforderten Wärmetauschfläche wird der gesamte Rippenwärmetauscher in seinen äußeren Abmaßen wesentlich kleiner. The rib profiling according to the invention actively participates in the heat exchange Rib area increased by approx. 60%. This allows a Finned heat exchanger the heat exchange surface and thus the compactness and Heat exchange performance can be increased significantly, or if a required is included The outer fin surface of the entire fin heat exchanger becomes a heat exchange surface much smaller.
