Description

Einrichtung zum Kühler' von Flächen, insbesondere bei Zylindern von Brennkraftmaschinen, mit Kühlrippentaschen Die bisher bekannten und angewandten Formen der Luftkühlung für Brennkraftmaschinen und Verdichter haben hauptsächlich-zwei Nachteile: sie bringen nicht genug Wärme weg und kühlen einseitig, d. h. die Seite, .auf welcher der Kühlluftstrom auftritt, wird stark gekühlt, die Rückseite dagegen zu wenig. Die vorliegende Erfindung beseitigt diese Mängel durch folgende Einrichtungen.Device for the cooler of surfaces, in particular for cylinders of Internal combustion engines, with cooling rib pockets The previously known and used Forms of air cooling for internal combustion engines and compressors have mainly two Disadvantages: they do not dissipate enough heat and cool on one side, i. H. the page, ., on which the cooling air flow occurs, is strongly cooled, the rear side on the other hand too little. The present invention overcomes these deficiencies by the following means.

Die in Richtung a anströmende Kühlluft fließt in die nach der Anströmseite. (SchnittA) hin offene, durch zwei Kühlrippen b gebildete Tasche, die auf der Rückseite durch die Wand c verschlossen ist und kann, da die Leitbleche d (nur in Abb. z eingezeichnet) das seitliche Abfließen verhindern, nur durch die öffnungen e in den Kühlrippen in die nächste Tasche abfließen (SchnittB).The cooling air flowing in in direction a flows into that after the upstream side. (Section A) open pocket formed by two cooling ribs b on the back is closed by the wall c and can, since the guide plates d (only shown in Fig.z) Prevent it from flowing off to the side, only through the openings e in the cooling fins flow into the next pocket (section B).

Diese Abflußtasche ist auf der Zuströmseite der Luft durch Wand f geschlossen, auf der Abflußseiteoffen; Schnitt C veranschaulicht den Weg der Luft durch die Kühlrippenöffnung e. Wesentlich ist, daß die Luft, um von der Zuströmtasche in die Abströmtasche zu kommen, auch um die Rückseite des Zylinders herumfließen muß und beim Durchfluß durch die Löcher oder Düsen e in den Kühlrippen auch auf die sonst im Windschatten liegenden Kühlrippenflächen auftritt und diese kühlt. Die Kühlwirkung wird durch die Wirbelung noch -erhöht, welche durch die zwangsläufige Richtungsänderung der Luft und Strahlenwirkung der Löcher hervorgerufen wird.This drain pocket is on the upstream side of the air through wall f closed, open on the drain side; Section C illustrates the path of air through the cooling fin opening e. It is essential that the air to get from the inflow pocket to get into the exhaust pocket, also flow around the back of the cylinder must and when flowing through the holes or nozzles e in the cooling fins also on the otherwise in the slipstream cooling fin surfaces occurs and cools them. The cooling effect is increased by the turbulence, which is increased by the inevitable Change of direction of the air and radiation effect of the holes is caused.

Die erwünschte Wirkung kann durch weitere Mittel verstärkt werden, durch Anwendung von Gebläse oder Absaugung wie auch durch düsenförmige Ansätze oder Leitformen an den öffnungene.The desired effect can be enhanced by other means, by using a blower or suction as well as nozzle-shaped approaches or Guide shapes on the openings.

Sinngemäß kann auch aus einer Zuströmtasche mit geschlossener Zuführung die Luft in beide danebenliegende Kühlringzonen frei ausströmen.Analogously, an inflow pocket with a closed inlet can also be used the air can flow freely into both adjacent cooling ring zones.
