Description

Kühleinrichtung für stromlinienförmig verkleidete Kraftwagen Die Erfindung betrifft eine Kühleinrichtung für stromlinienförmig verkleidete Kraftwagen und besteht darin, daß die Kühlluft an der Stauzone des Wagenbugs, d. h. an der Stelle größten Überdrucks, einströmt und ganz oder teilweise auf der Oberseite des Wagenbugs in der dort befindlichen Zone größten Unterdrucks ausströmt.Cooling device for streamlined motor vehicles The invention relates to a cooling device for streamlined motor vehicles and consists in that the cooling air at the stowage zone of the front of the car, d. H. largest at the point Overpressure, flows in and wholly or partially on top of the front of the wagon in the zone located there with the greatest negative pressure.

Ein Vorteil dieser Anordnung besteht darin, daß das größtmögliche Druckgefälle zwischen den Einströmöffnungen und den Ausströmöffnungen ausgenutzt ist. Bei wirkungsvoller Kühlung benötigt man dabei nur verhältnismäßig kleine Ein- und Ausströmöffnungen und vermindert daher den Gesamtluftwiderstand des Fahrzeugs bei hohem aerodynamischem Kühlergütegrad.An advantage of this arrangement is that the greatest possible Pressure gradient between the inflow openings and the outflow openings exploited is. With effective cooling, only relatively small inputs are required. and outflow openings and therefore reduces the overall aerodynamic drag of the vehicle with a high aerodynamic radiator quality.

Ferner entsteht bekanntlich .bei Kraftwagen mit vornliegender Maschine besonders im hinteren Teil des Motorraums vor der Trennwand zum Fahrgastraum eine starke Hitze-,entwicklung infolge der sich dort stauenden Hitze. Ein Anstieg der Temperatur im Fährgastrau,m und ein Übertritt von Motordünsten in diesen ist die Folge. Durch Absaugen der Kühlluft bzw. der durch die Maschine erhitzten Luft im Motorraten vorn in der Zone größten Unterdrucks sinkt aber die Temperatur hinten an der Trennwand zwischen Motor und Fahrgastraum und somit auch in diesem selbst.Furthermore, as is well known, occurs in motor vehicles with a forward engine especially in the rear part of the engine compartment in front of the partition wall to the passenger compartment intense heat development as a result of the heat accumulating there. An increase in Temperature in the Fährgastrau, m and a transfer of engine vapors in this is the Episode. By sucking off the cooling air or the air heated by the machine in the Motor rates at the front in the zone of greatest negative pressure, but the temperature at the rear drops on the partition wall between the engine and the passenger compartment and thus also in this itself.

In der Zeichnung ist in Fig. i und 2 ein schematisches Ausführungsbeispiel des Erfindungsgegenstandes dargestellt.In the drawing, a schematic embodiment is shown in FIGS of the subject matter of the invention.

i bedeutet den stromlinienförmig verkleideten Kraftwagen, 2 das Maschinenaggregat, 3 seitlich der Maschine angebrachte Kühler. 4. Schächte zur Führung des Kühlerluftstroms, einen besonderen Schacht für die Zuführung der zum Kühlen der Maschine dienenden Frischluft. 6 ist eine erfindungsgemäße Kühlluftaustrittsöifnung an der Oberseite des Wagenbugs.i means the streamlined car, 2 the machine unit, 3 coolers on the side of the machine. 4. shafts for guiding the cooler air flow, a special shaft for the supply of those used to cool the machine Fresh air. 6 is a cooling air outlet opening according to the invention on the upper side the front of the wagon.

Der Kühlerluftstrom tritt durch zwei öffnungen in der Stauzone des Bugs in den Wagen ein und wird durch Schächte 4, deren Wände hier gleichzeitig einen Teil der Radlaufverkleidungen bilden, auf die zu beiden Seiten der Maschine befindlichen Kühler 3 zugeleitet. Nach Durchströmen der Kühler tritt die Kühlluft in den Maschinenraum aus und vermengt sich dort mit der durch den Kühlluftschacht 5 von unten gesondert an die Maschine herangebrachten Frischluft. Sie verlä.ßt dann den Wagen durch die Auslaßöffnung 6 auf der Oberseite des Bugs im Bereich der Zone größten statischen Unterdrucks, wie in der an sich bekannten meridionalen Druckverteilungskurve (' = Überdruck, -=Unterdruck) in Fig. i schematisch dargestellt ist.The cooler air flow passes through two openings in the stowage zone of the Bugs into the car and is through shafts 4, the walls of which are here at the same time Form part of the wheel arch linings on the ones on both sides of the machine Cooler 3 fed. After flowing through the cooler, the cooling air enters the engine room and mixes there separately with the cooling air duct 5 from below fresh air brought to the machine. She then leaves the car through the Outlet opening 6 on the top of the bow in the area of the largest static zone Negative pressure, as in the known meridional pressure distribution curve (' = Overpressure, - = underpressure) is shown schematically in FIG.
