Description

  

      Ölkühler    für Automobilmotoren.    Bei modernen Automobilmotoren     errei-          chen    die Temperaturen während des Betriebes  häufig eine solche Höhe, dass     nicht    nur jeder  Zylinder     mittels    Wasser oder Luft, sondern  auch das Schmieröl gekühlt werden muss.  



  Die gewöhnlichen Lamellen- oder Röhren  ölkühler entsprechen diesem Zwecke nicht  hinreichend, und zwar einerseits wegen der  geringen Festigkeit des Kühlers, durch wel  chen,das Öl unter     bedeutendem    Druck zirku  liert, und anderseits deshalb, weil von dem  durch den     Kühler    mit grosser Geschwindig  keit geleiteten Öl nur die äusserste Schicht in  Berührung mit der     Kühlerwand    gelangt, was  infolge der geringen Wärmeleitfähigkeit des  Öls ein grosser Mangel für dessen Abküh  lung ist.  



  Gemäss der     Erfindung    zeichnet sich der       Ölkühler    durch einen aus zwei durch einen  Flansch verbundenen Teilen bestehenden       Körper    aus, der Hohlrippen besitzt, in deren  Innenraum     Teilungswände    eingesetzt sind mit    beidseitigen Ansätzen zur vollkommenen       Durchwirbelung    des     Öls    bei seinem Durch  fluss.  



  Ein     Ausführungsbeispiel    des Erfindungs  gegenstandes ist auf der Zeichnung schema  tisch veranschaulicht.  



       Fig.    1 zeigt     Iden        -Ölkühler    teilweise in  Ansicht,     teilweise    im Schnitt;       Fig.    2 ist ein Schnitt nach der Linie  2-2 der     Fig.    1.  



  Der mit Rippen besetzte Körper des Küh  lers besteht aus zwei Hälften 1 und 2, die       mittels    des     Flansches    3 miteinander     verbun-          ,den    sind.     In    die     hohlen    Rippen 4 sind Tei  lungswände 5     eingesetzt,    welche Ansätze G       besitzen,    die das     Öl    zur     Wirbelung        nötigen.     Die beiden Hälften des Kühlkörpers und  ebenso auch die     Teilungswände    5 sind aus  einem die Wärme gut     leitenden    Metall,

   wie  zum Beispiel Elektron oder ähnlichem gegos  sen, wodurch neben der grossen Festigkeit in  bezug auf den     Oldruck    auch eine gute           Wärmeableitung    erzielt wird. Die beiden  Hälften 1 und 2 können aber auch gepresst  sein.



      Oil coolers for automobile engines. In modern automobile engines, the temperatures often reach such a level during operation that not only each cylinder has to be cooled by means of water or air, but also the lubricating oil.



  The usual lamellar or tubular oil coolers do not adequately serve this purpose, on the one hand because of the low strength of the cooler through which the oil circulates under significant pressure, and on the other hand because it is passed through the cooler at high speed Only the outermost layer of oil comes into contact with the cooler wall, which is a major deficiency for its cooling due to the oil's low thermal conductivity.



  According to the invention, the oil cooler is characterized by a body consisting of two parts connected by a flange, which has hollow ribs, in the interior of which dividing walls are inserted with two-sided approaches to completely swirl the oil as it flows through.



  An embodiment of the subject invention is illustrated schematically in the drawing.



       Fig. 1 shows Iden oil cooler partly in view, partly in section; FIG. 2 is a section along line 2-2 of FIG. 1.



  The body of the cooler with ribs consists of two halves 1 and 2, which are connected to one another by means of the flange 3. In the hollow ribs 4 partition walls 5 are used, which have approaches G that require the oil to swirl. The two halves of the heat sink and also the partition walls 5 are made of a metal that conducts heat well,

   like, for example, electron or the like cast, which in addition to the great strength in relation to the oil pressure also achieves good heat dissipation. The two halves 1 and 2 can also be pressed.
