Description

Zylinder von Brennkraftmaschinen mit luftgekühlten Kühlpflöcken Zylinder von Brennkraftmaschinen mit luftgekühlten Kühlpflöcken sind bekannt. Von den bekannten Zylindern unterscheidet sich der vorliegende Erfindungsgegenstand dadurch, daß in den Zwischenräumen zweier Kühllappen Zapfen mit sich verjüngenden Lappen so angeordnet sind, daß die Kühlluftströme an den Stirnkanten der Lappen anstoßen und geteilt werden; hierdurch wird der Vorteil erreicht, daß die durchziehende kalte Luft genügend mit Wärme gesättigt wird.Cylinders of internal combustion engines with air-cooled cooling pegs cylinders of internal combustion engines with air-cooled cooling pegs are known. From the known The present subject matter of the invention differs from cylinders in that in the spaces between two cooling tabs cones with tapered tabs so arranged are that the cooling air flows abut the front edges of the flaps and split will; This has the advantage that the cold air passing through is sufficient becomes saturated with heat.

Der erfindungsgemäße- Zylinder oder das Gehäuse kann billig hergestellt werden und in dünnwandiger Form in einem Stück gegossen werden. Die Zeichnung zeigt den Erfindungsgegenstand in beispielsweiser Ausführung.The cylinder or housing according to the invention can be manufactured cheaply and cast in one piece in a thin-walled form. The drawing shows the subject matter of the invention in an exemplary embodiment.

Der in Abb. 2 gezeigte Zylinder ist nach einem besonders ausgearbeiteten Modell in einem Stück gegossen. Der Guß ist wirtschaftlich herzustellen, eine Verteuerung entsteht gegenüber anderen Zylindern nicht.The cylinder shown in Fig. 2 is based on a specially elaborated one Model cast in one piece. The casting is economical to manufacture, which is more expensive does not arise compared to other cylinders.

A sind lZippenstücke, B sind konische, verjüngende Lappen; Abb. t zeigt das Schema, der Anordnung. Vier Rippenstücke A besetzen in Form der Schachbrettanordnung die schwarzen Felder, in den dazwischenliegenden weißen Feldern befinden sich die verjüngenden Lappen B. Nach diesem Schema (Abb. i') ist also die ganze Oberfläche des Zylinders oder Gehäuses aufgeteilt. Die umspülende Luft bekommt hier dadurch eine Verteilung und eine Mischung der kalten und erwärmten Luftteilchen, weil der eintretende Luftstrom durch die Anordnung der Rippenstücke A und verjüngenden Lappen B den Luftstrom zur Verteilung bringt. Abb. a zeigt Luftstromrichtung Pfeil H. Es wird hierdurch erreicht, daß die durchströmende Luft immer wieder an neuen Kanten anstößt und von neuen Kanten abziehen muß. Kanten und Spitzen geben an die umspülende Luft die meiste Wärme ab. Während bei der gewöhnlichen Rippenkühlung die Luft zwischen zwei Kühlrippen ungehindert durchblasen kann, ist nach Anordnung der Rippenstücke A und verjüngenden Lappen B bei der Erfindung die Luft gezwungen, den vorgeschriebenen Weg zu gehen, d. 1i. die Luft kann nicht ungehindert durchblasen, sondern sie muß sich immer wieder teilen und muß immer wieder die vorstehenden Rippen A und die verjüngenden Lappen h erneut nacheinander umspülen. Dadurch, daß bei der vorliegenden -Erfindung möglichst viele Spitzen geschaffen wurden und die Luft gezwungen ist, durch die schachbrettförmige Anordnung der Rippenstücke und verjüngenden Lappen dieselben zu umspülen, ist eine ganz erheblich bessere Kühlung als bei den gewöhnlichen Kühlrippen erreicht.A are pieces of zipper, B are conical, tapering lobes; Fig. T shows the scheme, the arrangement. Four rib pieces A occupy in the form of the chessboard arrangement the black fields, the white fields in between are the tapering lobes B. According to this scheme (Fig. i ') is the whole surface of the cylinder or housing. The air around it gets through this a distribution and a mixture of cold and heated air particles because of the incoming air flow through the arrangement of the rib pieces A and tapered lobes B brings the air flow to the distribution. Fig. A shows the air flow direction arrow H. Es this ensures that the air flowing through is always at new edges butt and must pull off new edges. Edges and tips give to the wash around Air out most of the heat. While with the usual fin cooling the air between can blow through two cooling fins unhindered, is according to the arrangement of the fin pieces A and tapered lobes B in the invention forced the air to the prescribed Way to go d. 1i. the air cannot blow through unhindered, it must divide again and again and must again and again the protruding ribs A and the Rinse the tapered cloths again one after the other. The fact that with the present -Invention as many peaks as possible were created and the air is forced due to the checkered arrangement of the rib pieces and tapered lobes to wash around them is a considerably better cooling than with the usual ones Cooling fins reached.
