Definitions
- the invention relates to a cooling system for internal combustion engines according to the preamble of patent claim 1.
- a cooling system according to the preamble of claim 1 is described.
- the coolant is filled through a filling opening of the expansion tank when the cooling system is filled. From there it has to flow into the heat exchanger. The way there does not emerge from GB-A 2 116 921. There is also no information about the draining of the cooling system.
- the invention has for its object to provide a generic cooling system that can be quickly filled and emptied.
- expansion tank and the blower jacket are made in one piece and are designed as a carrier for the cooler.
- Such a carrier has the advantage that only a part has to be attached to the vehicle or to the internal combustion engine.
- the carrier can be made of plastic or metal, for example, so that the heat exchanger forming the cooler can be attached directly to the carrier without connecting lines.
- the fact that only one hose line package or a plug-in pipe connection has to be guided from the internal combustion engine to the carrier reduces the outlay on assembly and maintenance, since the parts can be preassembled and the entire package can therefore be replaced, for example.
- this has, at the geodetically lowest point on the carrier, an opening which opens into the surroundings and can be closed with a screw plug, which is connected to the interior of the expansion tank and the cooler.
- the opening and the screw plug are designed such that, in a screwed-in position of the screw plug, the interior of the expansion tank is blocked off from the interior of the cooler and from the environment, and the screw plug in a venting position connects the interior of the expansion tank and the interior of the cooler releases and at the same time shuts off both interiors from the environment.
- the screw plug is completely removed from the opening, so that the coolant in the cooler and in the expansion tank can be drained quickly and completely.
- the screw plug is up to a venting position screwed or unscrewed and a quick filling of the system is made possible by the direct connection of the interior of the expansion tank and cooler.
- the screw plug is then screwed in completely and the connection between the cooler and the expansion tank, which is normally not required and desired, is shut off.
- the expansion tank 1 includes a blower jacket 1 and a surge tank 2, the carrier being designed so that a cooler 3 can be attached to it or to the surge tank 2 directly without hose connections or the like.
- a filler neck 4 opens directly into the expansion tank 2.
- the rear wall 5 (FIG. 2) of the expansion tank can be made of a transparent material and have one or more markings 6 for, for example, minimum and maximum coolant level.
- the coolant supply line 7 and the coolant discharge line 8 to and from the cooler are routed to the blower jacket 1, so that only short connecting lines to the internal combustion engine are required.
- an opening 9 is provided, which extends via a connection 10 into the interior of the expansion tank 2 and via the cooling fluid supply line 7 into the interior of the cooler 3.
- connection 10 to the interior of the expansion tank 2 is closed by the screw plug 11 in its screwed-in position. If the screw plug 11 is brought into the venting position 12, there is a liquid connection from the interior of the cooler 3 via the coolant supply line 7 and the connection 10 to the interior of the expansion tank, and the coolant filled via the filler neck 4 passes directly into the entire cooling system. For normal operation of the internal combustion engine, the screw 11 is screwed in completely and the connection 10 is shut off. If the carrier is attached directly to the internal combustion engine, the coolant supply line 7 and coolant discharge line 8 can be designed such that they can be connected directly to the coolant pump of the internal combustion engine and to an outlet from the internal combustion engine. In the interior of the expansion tank 2 continues a connection piece 13, which forms a bypass return line to the coolant pump of the internal combustion engine. Otherwise, the cooling system according to the invention is suitable for any type of cooling liquid, such as oil or water.
Description
Die Erfindung betrifft ein Kühlsystem für Brennkraftmaschinen gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a cooling system for internal combustion engines according to the preamble of patent claim 1.
In der gattungsbildenden GB-A 2 116 921 ist eine Kühlanlage gemäß dem Oberbegriff des Anspruchs 1 beschrieben. Bei dieser Kühlanlage wird das Kühlmittel beim Befüllen der Kühlanlage durch eine Einfüllöffnung des Ausgleichbehälters eingefüllt. Von dort muß es in den Wärmetauscher fließen. Der Weg dorthin geht aus der GB-A 2 116 921 nicht hervor. Auch über die Entleerung des Kühlsystems ist keine Angabe gemacht.In the generic GB-A 2 116 921, a cooling system according to the preamble of claim 1 is described. In this cooling system, the coolant is filled through a filling opening of the expansion tank when the cooling system is filled. From there it has to flow into the heat exchanger. The way there does not emerge from GB-A 2 116 921. There is also no information about the draining of the cooling system.
Der Erfindung liegt die Aufgabe zugrunde, ein gattungsgemäßes Kühlsystem zu schaffen, das schnell befüllbar und entleerbar ist.The invention has for its object to provide a generic cooling system that can be quickly filled and emptied.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Ausgleichsbehälter und der Gebläsemantel einstückig gefertigt sind und als Träger für den Kühler ausgebildet sind.This object is achieved in that the expansion tank and the blower jacket are made in one piece and are designed as a carrier for the cooler.
Ein derartiger Träger hat den Vorteil, daß nur ein Teil an dem Fahrzeug oder an der Brennkraftmaschine befestigt werden muß. Dabei kann der Träger beispielsweise aus Kunststoff oder Metall so hergestellt werden, so daß der den Kühler bildende Wärmetauscher ohne Verbindungsleitungen direkt an den Träger befestigbar ist. Dadurch, daß nur ein Schlauchleitungspaket oder eine Steckrohrverbindung von der Brennkraftmaschine zu dem Träger geführt werden muß, wird der Montage- und Wartungsaufwand reduziert, da die Teile vormontiert werden können und somit das gesamte Paket beispielsweise austauschbar ist.Such a carrier has the advantage that only a part has to be attached to the vehicle or to the internal combustion engine. The carrier can be made of plastic or metal, for example, so that the heat exchanger forming the cooler can be attached directly to the carrier without connecting lines. The fact that only one hose line package or a plug-in pipe connection has to be guided from the internal combustion engine to the carrier reduces the outlay on assembly and maintenance, since the parts can be preassembled and the entire package can therefore be replaced, for example.
In vorteilhafter Weiterbildung des Kühlsystems weist dieses an geodätisch niedrigster Stelle des Trägers eine in die Umgebung mündende und mit einer Verschlußschraube verschließbare Öffnung auf, die mit dem Innenraum des Ausgleichsbehälters und des Kühlers verbunden ist. Dabei sind in weiterer Ausbildung der Erfindung die Öffnung und die Verschlußschraube so ausgebildet, daß in einer eingeschraubten Stellung der Verschlußschraube der Innenraum des Ausgleichbehälters von dem Innenraum des Kühlers und von der Umgebung abgesperrt ist und die Verschlußschraube in einer Entlüftungsstellung eine Verbindung zwischen dem Innenraum des Ausgleichsbehälters und dem Innenraum der Kühlers freigibt und gleichzeitig beide Innenräume zur Umgebung absperrt. Durch diese Ausbildung wird der Kühlflüssigkeitswechsel und Auffüllvorgang erleichtert. Zum Ablassen der Kühlflüssigkeit wird die Verschlußschraube komplett aus der Öffnung entfernt, so daß die in dem Kühler und in dem Ausgleichsbehälter befindliche Kühlflüssigkeit schnell und vollständig abgeführt werden kann. Beim Neuauffüllen bzw. Nachfüllen des Kühlsystems mit Kühlflüssigkeit wird die Verschlußschraube bis zu einer Entlüftungsstellung eingeschraubt bzw. herausgeschraubt und eine schnelle Befüllung des Systems ist durch die direkte Verbindung der Innenräume von Ausgleichsbehälter und Kühler ermöglicht. Nach der Auffüllung des Kühlsystems wird dann die Verschlußschraube ganz eingedreht und die im Normalfall nicht erforderliche und gewünschte Verbindung zwischen dem Kühler und dem Ausgleichsbhälter abgesperrt.In an advantageous development of the cooling system, this has, at the geodetically lowest point on the carrier, an opening which opens into the surroundings and can be closed with a screw plug, which is connected to the interior of the expansion tank and the cooler. In a further embodiment of the invention, the opening and the screw plug are designed such that, in a screwed-in position of the screw plug, the interior of the expansion tank is blocked off from the interior of the cooler and from the environment, and the screw plug in a venting position connects the interior of the expansion tank and the interior of the cooler releases and at the same time shuts off both interiors from the environment. This design makes it easier to change the coolant and fill it up. To drain the coolant, the screw plug is completely removed from the opening, so that the coolant in the cooler and in the expansion tank can be drained quickly and completely. When refilling or refilling the cooling system with coolant, the screw plug is up to a venting position screwed or unscrewed and a quick filling of the system is made possible by the direct connection of the interior of the expansion tank and cooler. After filling the cooling system, the screw plug is then screwed in completely and the connection between the cooler and the expansion tank, which is normally not required and desired, is shut off.
Weitere Vorteile der Erfindung sind der Zeichnungsbeschreibung zu entnehmen, in der ein in der Fig. dargestelltes Ausführungsbeispiel der Erfindung beschrieben ist.Further advantages of the invention can be found in the description of the drawing, in which an exemplary embodiment of the invention shown in the figure is described.

- Fig. 2:Fig. 2:
- einen Schnitt durch Fig. 1.a section through Fig. 1st
Der Träger gemäß Fig. 1 beinhaltet einen Gebläsemantel 1 und einen Ausgleichsbehälter 2, wobei der Träger so ausgelegt ist, daß ein Kühler 3 direkt ohne Schlauchverbindungen oder ähnliches an ihm bzw. an an dem Ausgleichsbehälter 2 befestigt werden kann. Ein Einfüllstutzen 4 mündet direkt in den Ausgleichsbehälter 2. Die Rückwand 5 (Fig. 2) des Ausgleichsbehälters kann aus einem durchsichtigen Material gefertigt sein und eine oder mehrere Markierungen 6 für beispielsweise minimale und maximale Kühlflüssigkeitsstandhöhe aufweisen. Die Kühlflüssigkeitszulaufleitung 7 und die Kühlflüssigkeitsablaufleitung 8 zu bzw. von dem Kühler sind bis zu dem Gebläsemantel 1 geführt, so daß nur kurze Verbindungsleitungen zur Brennkraftmaschine erforderlich sind. An geodätisch niedrigster Stelle des Trägers unterhalb des Ausgleichsbehälters 2 ist eine Öffnung 9 angebracht, die über eine Verbindung 10 in den Innenraum des Ausgleichsbehälters 2 und über die Kühlfüssigkeitszulaufleitung 7 in den Innenraum des Kühlers 3 hineinreicht. Die Verbindung 10 zu dem Innenraum des Ausgleichsbehälters 2 ist von der Verschlußschraube 11 in deren eingeschraubter Position verschlossen. Wird die Verschlußschraube 11 in die Entlüftungsstellung 12 gebracht, besteht von dem Innenraum des Kühlers 3 über die Kühlflüssigkeitszulaufleitung 7 und die Verbindung 10 zu dem Innenraum des Ausgleichsbehälters eine Flüssigkeitsverbindung und die über den Einfüllstutzen 4 eingefüllte Kühlflüssigkeit gelangt direkt in das gesamte Kühlsystem. Zum Normalbetrieb der Brennkraftmaschine wird die Schraube 11 ganz eingeschraubt und die Verbindung 10 abgesperrt. Wird der Träger direkt an der Brennkraftmaschine befestigt, können die Kühlflüssigkeitszulaufleitung 7 und Kühlflüssigkeitsablaufleitung 8 so ausgebildet sein, daß diese direkt mit der Kühlflüssigkeitspumpe der Brennkraftmaschine und einem Ablauf aus der Brennkraftmaschine verbunden werden können. In den Innenraum des Ausgleichsbehälters 2 mündet weiterhin ein Anschlußstutzen 13, der eine Nebenstromrücklaufleitung zu der Kühflüssigkeitspumpe der Brennkraftmaschine bildet. Im übrigen eignet sich das erfindungsgemäße Kühlsystem für jede Art von Kühlflüssigkeit, wie beispielsweise Öl oder Wasser.1 includes a blower jacket 1 and a
