Description

Die Erfindung bezieht sich auf einen solchen, insbesondere für Kraftfahrzeuge bestimmten Kühler, bei welchem in einem gemeinsamen Rahmen Strahlungselemente für das Kühlwasser und für das Schmieröl nebeneinander untergebracht sind. Gegenüber Kühlern ähnlicher Art besteht das Neue der Erfindung darin, daß das Strahlungselement für das Öl mit oberen und unteren Sammlern ausgestattet ist, die durch für die Sammler der seitlich dieses Strahlungselementes angeordneten Strahlungselemente für das Kühlwasser angeordnete Zwischenwände gebildet werden, und daß der untere Sammler des Strahlungselementes für das Öl in zwei Abteilungen für den Zu- und Abfluß des Öles mittels einer Scheidewand unterteilt ist, in welcher ein unter Federwirkung stehendes Ventil eingesetzt ist, durch das die beiden Abteilungen unmittelbar miteinander verbunden werden können. Diese Ausbildung ergibt bei einfacher Bauart sowie günstiger und zuverlässiger Wirkungsweise eine vorteilhafte und den verfügbaren Raum gut ausnutzende Gesamtanordnung der verschiedenen Strahlungselemente. Hierbei wird ferner durch die Anbringung des Federventils in der Scheidewand der beiden unteren Sammelabteilungen unter Vermeidung von besonderen Stutzen und Außenleitungen die Sicherheit geboten, daß im Falle eines Überdruckes im Strahlungselement für das öl, welcher beispielsweise in kalter Jahreszeit durch Stauung oder Verdickung des Öles in den Kühlrohren verursacht werden kann, die Zuflußabteilung des unteren Sammlers unmittelbar mit der Abflußabteilung ' desselben verbunden wird und dadurch Betriebsstörungen und Beschädigungen in dem Strahlungselement vermieden werden. Die Unterteilung des unteren Sammlers für das Öl kann so vorgenommen werden, daß die beiden hierdurch gebildeten Röhrgruppen des zugehörigen Strahlüngselementes nebeneinanderliegen, also in gleicher Weise von der Kühlluft durchstrichen werden. Zweckmäßig wird die Unterteilung jedoch so vorgenommen, daß die beiden hierdurch gebildeten Rohrgruppen hintereinanderliegen und das zu kühlende Öl von der hinteren Gruppe in die vordere Gruppe umläuft. Hierdurch wird eine wirtschaftlichere Kühlwirkung erzielt, da das Öl infolgedessen gewissermaßen im Gegenstrom zum Luftstrom umläuft und in den Kühlrohren der hinteren und vorderen Gruppe ein gleichmäßiger Temperaturabfall bewirkt wird.The invention relates to such, in particular intended for motor vehicles Cooler, in which in a common frame radiating elements for the cooling water and the lubricating oil are housed next to each other. Compared to coolers Similarly, the novelty of the invention is that the radiating element for the oil with upper and lower collectors is equipped, which is arranged by the side of this radiation element for the collector Radiating elements arranged for the cooling water intermediate walls are formed, and that the lower collector of the Radiant element for the oil in two compartments for the inflow and outflow of the oil is divided by means of a partition, in which a spring-loaded Valve is used through which the two departments are directly connected can be. This training results in an advantageous with a simple design and inexpensive and reliable mode of operation and overall arrangement of the various radiating elements that makes good use of the available space. Here is also by attaching the spring valve in the septum of the two lower collecting compartments while avoiding special nozzles and external lines, the safety required that in the event of overpressure in the radiating element for the oil, which for example in the cold season can be caused by stagnation or thickening of the oil in the cooling pipes, the inflow section of the lower collector is connected directly to the drainage compartment 'of the same and thereby avoid malfunctions and damage in the radiating element will. The subdivision of the lower collector for the oil can be done in this way that the two tube groups of the associated Strahlüngselementes thus formed are next to each other, so swept through in the same way by the cooling air will. However, the subdivision is expediently made in such a way that the two thereby formed pipe groups lie one behind the other and the oil to be cooled from the rear Group circulates in the front group. This creates a more economical cooling effect achieved, as the oil as a result circulates in countercurrent to the air flow and in the cooling tubes of the rear and the front group causes a uniform temperature drop.

Der Erfindungsgegenstand ist auf der Zeichnung unter Zugrundelegung der letzteren Anordnung in einem Ausführungsbeispiel veranschaulicht.The subject of the invention is on the drawing based on the latter Arrangement illustrated in one embodiment.

Kühl- oder Strahlungselemente 2,21 und 3 untergebracht, derart, daß sich das zum Kühlen des Öles dienende Strahlungselement 3 in der Mitte befindet und die beiden Strahlungselemente 2,21 zum Kühlen des Wassers sich auf beiden Seiten des Kühlelementes 3 befinden. Die "Wasserkühler 2, 21 bestehen nach bekannten Ausführungen aus bienenkorbartigen Elementen, die oben mit einem Wasserzuflußsammler 4 und unten mit einem Wasserabflußsammler 5 versehen sind.Cooling or radiating elements 2, 2 1 and 3 housed in such a way that the radiating element 3 serving to cool the oil is located in the middle and the two radiating elements 2, 2 1 for cooling the water are located on both sides of the cooling element 3. According to known designs, the "water coolers 2, 2 1" consist of beehive-like elements which are provided with a water inflow collector 4 at the top and a water outflow collector 5 at the bottom.

Die abgeplatteten Rohrbündel 8, 81 des mittleren Strahlungselementes 3 münden einerseits in einen oberen Sammler 7 und andererseits in einen unteren Sammler 6, 61, welche in den Wasserzufluß- und Wasserabflußsammlern 4 und 5 durch für die seitlichen Strahlungselemente vorgesehene Zwischenwände 11 gebildet werden. Der obere Sammler 7 des mittleren Strahlungselementes bildet eine einzige nAbteilung. Der untere Sammler ist hingegen durch eine Scheidewand 10 in zwei Abteilungen 6 und 61 unterteilt, von denen die Abteilung 6 an den Ölzufluß und die Abas teilung 61 an den ÖlabfLuß angeschlossen ist. Auf diese Weise wird das Öl gezwungen, das mittlere Strahlungselement 3 in zwei Rohrgruppen 8 und 81 zu durchfließen. The flattened tube bundles 8, 8 1 of the central radiating element 3 open on the one hand into an upper collector 7 and on the other hand into a lower collector 6, 6 1 , which are formed in the water inflow and water outflow collectors 4 and 5 by partition walls 11 provided for the lateral radiating elements. The upper collector 7 of the central radiation element forms a single compartment. The lower collector, however, is divided by a partition 10 into two departments 6 and 6 1 , of which the department 6 is connected to the oil inflow and the Abas division 6 1 is connected to the oil outflow. In this way, the oil is forced to flow through the central radiating element 3 in two tube groups 8 and 8 1.

Wie insbesondere aus Abb. 2 und 4 ersichtlich ist, ist die Unterteilung des unteren Sammlers durch die Scheidewand 10 so vorgenommen, daß die beiden hierdurch gebildeten Rohrgruppen 8 und 81 in Richtung der durchströmenden Kühlluft hintereinanderliegen und das Öl von der hinteren Rohxgruppe 8 in die vordere Rohrgruppe 81 umläuft. As can be seen in particular from Figs. 2 and 4, the subdivision of the lower collector by the partition wall 10 is made so that the two tube groups 8 and 8 1 formed in this way lie one behind the other in the direction of the cooling air flowing through and the oil from the rear Rohxgruppe 8 into the front pipe group 8 1 revolves.

In der Scheidewand 10 ist eine Durchflußöffhung vorgesehen, welche durch ein unter Federwirkung stehendes Ventil 9 geschlossen gehalten wird. Das Ventil 9 ist so eingestellt, daß es bei normalen Betriebsverhältnissen die Abteilung 6 gegen die Abteilung 61 abschließt, daß es sich aber, falls in der Kam-♦5 mer 6 eine D.rucksteigerung von bestimmter Größe eintritt, in Richtung des Pfeiles der Abb. 4 selbsttätig öffnet und eine unmittelbare Verbindung zwischen den beiden Abteilungen 6 und 61 herstellt.In the partition 10 a throughflow opening is provided which is kept closed by a valve 9 under the action of a spring. The valve 9 is set in such a way that, under normal operating conditions , it closes the compartment 6 from the compartment 6 1 , but if there is a pressure increase of a certain size in the chamber 6, in the direction of the arrow Fig. 4 opens automatically and creates a direct connection between the two departments 6 and 6 1 .

Die Arbeitsweise des Kühlers ist folgende: Der Sammler 4 erhält das vom Motor erwärmte Wasser und leitet es dem Sammler 5 durch die bienenkorbartigen Elemente 2,21 zu, wo es vor seiner Rückkehr zum Motor die erforderliche Abkühlung erfährt.The operation of the cooler is as follows: The collector 4 receives the water heated by the engine and forwards it to the collector 5 through the beehive-like elements 2, 2 1 , where it undergoes the required cooling before it is returned to the engine.

Die als Zuflußsammler wirkende Kammer 6 erhält das Schmieröl, das in den in dije Kammer 7 mündenden Rohrbündeln 8 steigt, um dann durch das Rohrbündel 81 herabzufließen und sich in der als Abflußsammler wirkenden Kammer 61 anzusammeln.The chamber 6 acting as an inflow collector receives the lubricating oil, which rises into the tube bundles 8 opening into the chamber 7, in order then to flow down through the tube bundle 8 1 and collect in the chamber 6 1 acting as an outflow collector.

Dieser zwangläufige Weg, den das Schmieröl zurückzulegen hat, bewerkstelligt eine wirtschaftliche Ausbeutung des Kühlvermögens der Luft, da die Rohrbündel 81 mit dem herabfließenden halb abgekühlten Öl von der frischen Luft bespült werden, während die bereits lauwarme Luft auf die hinteren Rohrbündel 8 einwirkt, so daß der Temperaturabfall zwischen den Bündeln und der auf sie einwirkenden Luft praktisch fast konstant ist.This inevitable path, which the lubricating oil has to cover, brings about an economic exploitation of the cooling capacity of the air, since the tube bundles 8 1 are flushed with the half-cooled oil flowing down from the fresh air, while the already lukewarm air acts on the rear tube bundle 8, so that the temperature drop between the bundles and the air acting on them is practically almost constant.

Tritt im Falle einer Stauung des Öles, wie z. B. im Winter durch die Verdickung desselben, ein unzulässiger überdruck ein, der größer als die Spannung der Feder des Ventils 9 ist, so öffnet sich dieses selbsttätig und verbindet die Kammer 6 unmittelbar mit der Kammer 61, wodurch das Öl sofort zum Motor zurückfließt, ohne in die Rohrbündel zu gelangen. Eine Kühlung ist in diesem Fall nicht nötig, da eine Stauung des Öles nur bei niedriger Temperatur eintritt, also eine Kühlung überflüssig wird.Occurs in the event of a stagnation of the oil, such. B. in winter due to the thickening of the same, an impermissible overpressure that is greater than the tension of the spring of the valve 9, this opens automatically and connects the chamber 6 directly to the chamber 6 1 , whereby the oil immediately flows back to the engine without getting into the tube bundle. In this case, cooling is not necessary, as the oil only accumulates at a low temperature, meaning that cooling is superfluous.
