Abstract

Die Erfindung betrifft luftgekühlte Kühler mit mindestens zwei nacheinander von Kühlluft durchströmten Kühlebenen für zu kühlende Flüssigkeiten, wobei deren Kühlerelemente Anschlüsse zur Verbindung untereinander aufweisen.The invention relates to air-cooled radiator with at least two successive of Cooling air flowed through Kühlebenen for liquids to be cooled, with their Radiator elements have connections for connection with each other.

Es wird die Aufgabe gelöst, luftgekühlte Kühler vorgenannter Art mit geringer Anströmfläche, gutem Wirkungsgrad und hoher Temperaturdifferenz zwischen Zuund Abfluss zu realisieren, die vorteilhaft für zu kühlende Fahrzeugaggregate einsetzbar sind.The object is achieved, air-cooled radiator of the aforementioned type with less Flow surface, good efficiency and high temperature difference between Zuund To realize drain, which is advantageous for cooling vehicle units can be used.

Erfindungsgemäß wird dies durch folgende Gestaltung erreicht:

  • mindestens zwei nacheinander vom zu kühlenden Medium (M) durchflossene Kühlereinheiten (2; 3) sind ohne wesentlichen direkten Wärmeübergang hintereinanderliegend angeordnet,
  • die an der Anströmseite zuerst von der Kühlluft (KL) beaufschlagte vordere Kühlereinheit (2) weist den Abfluss (A2) für das zu kühlende Medium (M) und die von der Kühlluft (KL) letztlich beaufschlagte hintere Kühlereinheit (3) den Zufluss (Z3) für das zu kühlende Medium (M) auf.
Figure 00000001
According to the invention this is achieved by the following design:
  • at least two cooler units (2, 3) through which the medium to be cooled flows in succession are arranged one behind the other without substantial direct heat transfer,
  • the front radiator unit (2) acted upon first by the cooling air (KL) on the inflow side, has the outflow (A2) for the medium to be cooled (M) and the rear radiator unit (3) finally acted upon by the cooling air (KL) ) for the medium to be cooled (M).
