Description

  

      Wärmeaustauscher.       Gegenstand der Erfindung ist ein     Wärme-          austauscher    mit Rippenrohr. Das Rippenrohr  des erfindungsgemässen     Wärmeaustausöhers     hat einen     tropfenprofilartigen    Querschnitt.  



  Ein Ausführungsbeispiel des Erfindungs  gegenstandes ist auf der Zeichnung im Quer  schnitt dargestellt.  



  Das mit einer Anzahl rechteckiger Rip  pen 1 versehene Rohr 2 hat     tropfenprofil-          artigen        Querschnitt,    konstruiert nach den  Strömungsgesetzen der Aerodynamik. Solche       Wärmeaustauscher    werden in der Regel zu  einem Aggregat neben- und hintereinander  zusammengebaut. Dieses in einer     Heiz-    oder  Kühleinrichtung zum Wärmeaustausch be  nützte Aggregat wird meistens von einem  Luftstrom in der Richtung der Längsachse  des Rohrquerschnittes durchstrichen, und  zwar vorteilhaft in der Richtung von der    breiteren nach der schmäleren Seite hin, in  der Zeichnung von links nach rechts.  



  Durch den     tropfenprofilartigen    Querschnitt  des Rippenrohres wird nun bekannten Wärme  austauschern mit im Querschnitt elliptischen  Rippenrohren gegenüber der Vorteil erzielt,  dass das Rohr der auf dasselbe aufprallenden  Luft eine grössere     Wärmeaustauschfläche     bietet, die Luft anfänglich stärker seitwärts  bewegt und mischt und     infolgedessen    auch  ein besserer Wärmeaustausch unter den Tei  len des Luftstromes, das heisst eine gleich  mässigere Erwärmung     resp.    Kühlung des  ganzen     Luftstromes    erzielt wird.



      Heat exchanger. The invention relates to a heat exchanger with a finned tube. The finned tube of the heat exchanger according to the invention has a teardrop profile-like cross section.



  An embodiment of the subject invention is shown in the drawing in cross section.



  The tube 2, which is provided with a number of rectangular ribs 1, has a teardrop profile-like cross-section, constructed according to the flow laws of aerodynamics. Such heat exchangers are usually assembled into a unit next to one another and one behind the other. This aggregate used in a heating or cooling device for heat exchange is mostly traversed by an air flow in the direction of the longitudinal axis of the pipe cross-section, advantageously in the direction from the wider to the narrower side, in the drawing from left to right.



  Due to the teardrop profile-like cross-section of the finned tube, known heat exchangers with finned tubes with an elliptical cross-section are now achieved over the advantage that the tube offers the air impinging on it a larger heat exchange surface, the air initially moves more sideways and mixes and, as a result, a better heat exchange between the Parts of the air flow, that is, a more even heating, respectively. Cooling of the whole air flow is achieved.
