Die Erfindung betrifft einen Ausgleichsbehälter (2) für einen Kühlkreislauf einer Brennkraftmaschine mit mindestens einem Zufluss- (8, 10) und einem Abflussanschluss (12), die beide mit dem Kühlkreislauf verbunden sind, einem im Behälter ausgebildeten Kammersystem, in dem Kühlflüssigkeit aufgenommen ist, wobei die einzelnen Kammern (26a bis 26l) zumindest teilweise über Öffnungen (29a bis 29i bzw. 30a bis 30g) miteinander verbunden sind und dass ein mit dem Zuflussanschluss verbundenes Kühlwasserrohr (8, 10) in eine der Kammern einmündet, in der ein Prallelement (21, 22) für die einströmende Kühlflüssigkeit vorgesehen ist. Es wird vorgeschlagen, dass das Prallelement (21, 22) als bogenförmige Leitwand ausgebildet ist, an der die einströmende Kühlflüssigkeit gezielt entlang geführt wird. DOLLAR A Damit wird u. a. eine Verschäumung des in den Ausgleichsbehälter einströmenden Kühlfluids unterbunden.The invention relates to an expansion tank (2) for a cooling circuit of an internal combustion engine with at least one inflow (8, 10) and one outflow connection (12), both of which are connected to the cooling circuit, a chamber system in the tank, in which coolant is received, The individual chambers (26a to 26l) are at least partially connected to one another via openings (29a to 29i or 30a to 30g) and that a cooling water pipe (8, 10) connected to the inflow connection opens into one of the chambers in which a baffle element ( 21, 22) is provided for the inflowing coolant. It is proposed that the baffle element (21, 22) be designed as an arcuate guide wall, along which the incoming cooling liquid is guided in a targeted manner. DOLLAR A a. foaming of the cooling fluid flowing into the expansion tank is prevented.
Description
Die Erfindung betrifft einen Ausgleichsbehälter für einen Kühlkreislauf einer Brennkraftmaschine nach dem Oberbegriff des Patentanspruchs 1.The invention relates to an expansion tank for a Cooling circuit an internal combustion engine according to the preamble of the claim 1.
Aus der
Der Erfindung liegt daher die Aufgabe zugrunde, in einem Kühlwasser – Ausgleichsbehälter Maßnahmen vorzusehen, bei denen in allen möglichen Fahrsituationen des Kraftfahrzeuges (z.B. Berg- oder Talfahrten, Kurvenfahrten mit hoher Querbeschleunigung) das aus den Kühlwasserrohren austretende und mit Gasblasen angereicherte Kühlwasser so abgebremst wird, dass eine Schaumbildung im Ausgleichsbehälter weitestgehend vermieden wird. Gleichzeitig soll die in den Ausgleichsbehälter einströmende Kühlflüssigkeit entlüftet werden, bevor sie dem eigentlichen Kühlkreislauf der Brennkraftmaschine wieder zugeführt wird.The invention is therefore the object based on measures taken in a cooling water expansion tank to provide for in all sorts Driving situations of the motor vehicle (e.g. ascent or descent, Cornering with high lateral acceleration) that emerging from the cooling water pipes and cooling water enriched with gas bubbles is slowed down so that foam formation in the expansion tank is largely avoided becomes. At the same time, the coolant flowing into the expansion tank should be vented before the actual cooling circuit is fed back to the internal combustion engine.
Die Aufgabe wird erfindungsgemäß mit den Merkmalen des Patentanspruchs 1 gelöst.The object is achieved with the features of claim 1 solved.
Die Anordnung der Kühlwasserrohre im Ausgleichsbehälter sind mit dem Flüssigkeitsspiegel im Ausgleichsbehälter so abgestimmt, dass im Normalfall die Kühlwasserrohre in Höhe bzw. unterhalb des Flüssigkeitsspiegels einmünden. Damit wird eine Schaumbildung im wesentlichen dadurch verhindert, dass die kinetische Energie des einströmenden Wasser/Gas-Gemisches durch die höhere Viskosität der Flüssigkeit im Ausgleichsbehälter effektiv abgebaut wird. Insbesondere bei Berg- oder Talfahrten ist jedoch nicht mehr sichergestellt, dass die aus den Kühlwasserrohren austretende Kühlflüssigkeit noch unterhalb bzw. in Höhe des Flüssigkeitsspiegels einmündet. In diesem Fall gewährleisten die im Ausgleichsbehälter vorgesehenen bogenförmigen Leitwände, dass die kinetische Energie des einströmenden Kühlwassers kontinuierlich abgebaut wird, so dass auch in diesen Fahrsituationen eine Schaumbildung weitestgehend vermieden wird.The arrangement of the cooling water pipes in the expansion tank are with the liquid level in the expansion tank coordinated so that the cooling water pipes in height or below the liquid level open out. Foaming is essentially prevented by the fact that the kinetic energy of the inflowing water / gas mixture through the higher viscosity the liquid in the expansion tank is effectively broken down. Especially when driving uphill or downhill however, no longer ensured that those from the cooling water pipes leaking coolant still below or in height of the liquid level opens. In this case, ensure the one in the expansion tank provided arcuate baffles that the kinetic energy of the incoming cooling water is continuously reduced so that foaming occurs even in these driving situations is largely avoided.
Weitere Vorteile und vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen und der Beschreibung.Other advantages and beneficial Embodiments of the invention result from the subclaims and the description.
Eine besonders wirkungsvolle Anbindung der einströmenden Kühlflüssigkeit ergibt sich, wenn das in die Kammer mit der Leitwand einmündende Kühlwasserrohr mit seiner Auslassmündung so ausgerichtet ist, dass die ausströmende Kühlflüssigkeit etwa tangential auf die bogenförmige Leitwand auftrifft.A particularly effective connection to the incoming coolant arises when the cooling water pipe opening into the chamber with the baffle with its outlet mouth is aligned so that the outflowing coolant is approximately tangential the arched Baffle meets.
Der in vorteilhafter Weise aus Kunststoff bestehende Ausgleichsbehälter besteht aus einer Ober- und Unterschale, wobei in der Oberschale die Leitwand und das Kühlwasserrohr integriert ist.The advantageously made of plastic existing expansion tank consists of an upper and lower shell, with the upper shell the baffle and the cooling water pipe is integrated.
In der Oberschale ist ebenfalls ein Kammersystem ausgebildet, bei denen die Wände der einzelnen Kammern zum Druckausgleich über Öffnungen miteinander verbunden sind. Dabei sind u. a. Durchbrüche vorgesehen, durch die das Kühlwasserrohr hindurchgeführt ist; diese Durchbrüche sind dabei so dimensioniert, dass sie gleichzeitig als die Kammern verbindende Öffnungen zur Verfügung stehen.There is also a in the upper shell Chamber system designed in which the walls of the individual chambers to Pressure equalization via openings with each other are connected. Here are u. a. Breakthroughs provided through which Cooling water pipe is passed through; these breakthroughs are dimensioned so that they simultaneously serve as openings connecting the chambers to disposal stand.
Damit das in den Ausgleichsbehälter einströmende Kühlwasser genügend Zeit zum Entschäumen hat, ist der Austritt der Kühlflüssigkeit aus dem Kühlwasserrohr sowie die Leitwand in der – bezogen auf den Abflussanschluss – hintersten Kammerreihe angeordnet.So that the cooling water flowing into the expansion tank enough Time to defoam is the outlet of the coolant from the cooling water pipe as well as the baffle in the - based on the drain connection - rearmost Arranged row of chambers.
In der Oberschale des Ausgleichsbehälters sind auf vorteilhafte Art und Weise zwei in das Kammersystem einmündende Kühlwasserrohre vorgesehen, bei der das erste Kühlwasserrohr mit einem Kühler und das zweite Kühlwasserrohr mit dem Wassermantel des Zylinderkopfes der Brennkraftmaschine in Verbindung steht.Are in the top shell of the expansion tank advantageously two cooling water pipes opening into the chamber system provided in which the first cooling water pipe with a cooler and the second cooling water pipe with the water jacket of the cylinder head of the internal combustion engine in Connection is established.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird nachfolgend näher erläutert.An embodiment of the invention is shown in the drawing and is explained in more detail below.
