Die vorliegende Erfindung beschäftigt sich mit dem Problem, für eine Kühleinrichtung der gattungsgemäßen Art, eine verbesserte Ausführungsform anzugeben, welche einfach zu fertigen und exakt zu steuern bzw. zu regeln ist und zugleich einen konstruktiv einfachen Aufbau aufweist.The The present invention addresses the problem of for a cooling device of the generic type Art to provide an improved embodiment which is easy to manufacture and to control exactly and is and at the same time has a structurally simple structure.
Dieses Problem wird erfindungsgemäß durch den Gegenstand des unabhängigen Anspruchs 1 gelöst. Vorteilhafte Ausführungsformen sind Gegenstand der abhängigen Ansprüche.This Problem is inventively by the subject of the independent claim 1 solved. advantageous Embodiments are the subject of the dependent Claims.
Die vorliegende Erfindung beruht auf dem allgemeinen Gedanken, eine Kühleinrichtung zur Kühlung von Abgasen in einem Kraftfahrzeug mit einem Gehäuse aus Metalldruckguss auszustatten und in diesem Gehäuse sowohl einen ersten Kanal, in welchem eine Wärmeübertragungseinrichtung angeordnet ist, als auch einen zweiten Kanal, welcher als Bypasskanal ausgebildet ist und die Wärmeübertragungseinrichtung umgeht, zu integrieren. Zumindest der zweite Kanal wird dabei durch Gehäusekonturen gebildet, die einen integralen Bestandteil des Metalldruckgussgehäuses bilden. Separate Teile zur Realisierung der einzelnen Kanäle sind dadurch entbehrlich, so dass zur Fertigung der erfindungsgemäßen Kühleinrichtung lediglich noch die Wärmeübertragungseinrichtung im ersten Kanal positioniert bzw. angeordnet werden muss und anschließend das Gehäuse geschlossen werden kann, wobei durch die integral vorgesehenen Gehäusekonturen beim Schließen des Gehäuses bereits die beiden Kanäle gebildet werden. Denkbar ist hierbei selbstverständlich auch, dass auch die Wärmeübertragungseinrichtung einen integralen Bestandteil des Gehäuses, beispielsweise in der Art von angeformten Kühlrippen, bildet. Separat vorzusehende Trennwände sind dadurch gleichfalls entbehrlich, wodurch die erfindungsgemäße Kühleinrichtung konstruktiv einfach aufgebaut ist. Darüber hinaus ist durch die Verwendung von Metalldruckguss für das Gehäuse ein nahezu temperaturunempfindlicher Werkstoff gefunden, welcher selbst hohen Temperaturen, wie sie bspw. in einem Abgasstrang einer Brennkraftmaschine auftreten können, problemlos standhält. Das Vorsehen der Gehäusekonturen, welche beim Zusammenbau des Gehäuses zumindest den zweiten Kanal in demselben bilden, ist durch eine entsprechend einfache Auslegung bzw. Ausbildung einer Spritzgussform realisierbar. Mit dem erfindungsgemäßen und aus Metalldruckguss ausgebildeten Gehäuse, welches durch seine Ausbildung bereits die zwei innenliegenden Kanäle formt, können aufwendige Montageprozesse sowie die Teilevielfalt bei der Herstellung der erfindungsgemäßen Kühleinrichtung deutlich reduziert werden.The The present invention is based on the general idea, a Cooling device for cooling exhaust gases in one To equip motor vehicle with a housing of die-cast metal and in this housing both a first channel in which a heat transfer device is arranged, as well as a second channel, which is designed as a bypass channel is and bypasses the heat transfer device, to integrate. At least the second channel is formed by housing contours, which is an integral part of the metal die-cast housing form. Separate parts to realize the individual channels are dispensable, so that for the production of the cooling device according to the invention only the heat transfer device must be positioned or arranged in the first channel and then the housing can be closed, being replaced by the integral provided housing contours when closing the Housing already formed the two channels. It is conceivable, of course, that too the heat transfer device an integral Part of the housing, for example in the manner of molded cooling fins forms. Separate partition walls are thereby also dispensable, whereby the inventive Cooling device is structurally simple. About that In addition, through the use of metal die casting for the housing a nearly temperature-insensitive material found, which even high temperatures, such as in a Exhaust line of an internal combustion engine can occur easily withstood. The provision of housing contours, which during assembly of the housing at least the second Make channel in the same is by a suitably simple design or training an injection mold feasible. With the invention and die-cast housing formed by his education already the two inside channels forms, complex assembly processes as well as the variety of parts in the manufacture of the cooling device according to the invention be significantly reduced.
Bei einer vorteilhaften Weiterbildung der erfindungsgemäßen Lösung, ist eine schwenkbare Bypassklappe vorgesehen, durch welche eine Strömungsaufteilung zwischen dem ersten und dem zweiten Kanal erfolgt. Die Bypassklappe wird dabei von einer entsprechenden Steuerungs-/Regelungseinrichtung angesteuert bzw. geregelt und teilt die in der Kühleinrichtung fließende Strömung auf den ersten bzw. zweiten Kanal auf. In einer ersten Extremalstellung der Bypassklappe strömt die gesamte Strömung durch den ersten Kanal und nichts durch den zweiten Kanal, während dies bei der zweiten Extremalstellung der schwenkbaren Bypassklappe genau umgekehrt der Fall ist. In stufenlos einstellbaren Zwischenstellungen kann dabei die Strömung zwischen den beiden Kanälen nahezu beliebig aufgeteilt werden. Eine derartige schwenkbare Bypassklappe ermöglicht ein äußerst exaktes und zugleich bezüglich der erforderlichen Teile kostengünstiges Steuern des in der Kühleinrichtung strömenden Gasstroms.In an advantageous development of the solution according to the invention, a pivotable bypass flap is provided, through which a flow division between the first and the second channel takes place. The bypass flap is controlled or regulated by a corresponding control / regulating device and divides the flowing in the cooling device flow to the first and second channel. In a first extreme position of the bypass flap, the entire flow flows through the first channel and nothing through the second channel, while in the second extreme position of the pivotable bypass flap is exactly the case. In infinitely adjustable intermediate positions, the flow between The two channels can be divided almost arbitrarily. Such a pivotable bypass flap allows a very precise and at the same time with respect to the required parts cost-effective control of the flowing gas stream in the cooling device.
Bei einer vorteilhaften Ausführungsform der erfindungsgemäßen Lösung, ist das Gehäuse als Leichtmetalldruckgussgehäuse, insbesondere aus Aluminiumdruckguss, ausgebildet. Aluminium wird aufgrund seiner geringen Dichte gern dort verwendet, wo es auf die Masse eines Transportmittels ankommt, weil diese bspw. zum Treibstoffverbrauch beiträgt. Werden hierbei Legierungselemente, wie bspw. Magnesium, Silizium oder andere Metalle zugemischt, können Festigkeiten erreicht werden, die denen von Stahl nur wenig nachstehen. Aluminium besitzt neben dem geringen Gewicht eine äußerst gute Wärmeleitfähigkeit und ist dadurch prädestiniert für den Einsatz in Wärmeübertragungseinrichtungen. So können bspw. an dem Gehäuse Kühlkonturen, wie Kühlrippen angeformt sein, die eine Kühlung des durchströmenden Abgasstroms bewirken, wobei aufgrund der hohen Wärmeleitfähigkeit des Aluminiums ein besonders guter Wärmeaustausch gewährleistet werden kann.at an advantageous embodiment of the invention Solution, is the housing as a light metal die-cast housing, in particular of diecast aluminum, formed. Aluminum is due its low density likes to be used where it is on the ground a means of transport arrives, because this contributes, for example, to fuel consumption. Be here alloying elements, such as magnesium, silicon or mixed with other metals, strengths can be achieved which are only slightly inferior to steel. Has aluminum In addition to the low weight, an extremely good thermal conductivity and is thus predestined for use in heat transfer facilities. So can For example, on the housing cooling contours, such as cooling fins be formed, which is a cooling of the flowing through Cause exhaust gas flow, due to the high thermal conductivity the aluminum a particularly good heat exchange can be ensured can.
Bei einer vorteilhaften Weiterbildung der erfindungsgemäßen Lösung, ist das Gehäuse zweiteilig aufgebaut, wobei an zumindest einem der beiden Gehäuseteile Kühlkonturen, insbesondere Kühlrippen ausgebildet sind, die in den ersten Kanal, vorzugsweise senkrecht zur Strömungsrichtung hineinragen. Die Kühlkonturen erzwingen dabei ein Umströmen derselben durch das heiße Abgas und aufgrund ihrer großen Oberfläche einen intensiven Wärmeaustausch. Zur Erhöhung der Kühlwirkung, können die Kühlkonturen hohl ausgebildet sein und von einem Kühlfluid durchströmt werden. Das Kühlfluid kann dabei bspw. aus einem Kühlkreislauf, welcher ebenfalls die Brennkraftmaschine kühlt, entnommen werden, so dass mit dem heißen Abgas bspw. eine Aufwärmehase der Brennkraftmaschine deutlich verkürzt und dadurch die Insbesondere in diesem Stadium hohe NOx-Emissionen reduziert werden können. Generell können derartige Kühleinrichtungen auch zu einer Erwärmung eines Fahrgastraums verwendet werden, wobei das Hauptaugenmerk darauf gerichtet ist, die Abgastemperatur vor der Zuführung zu einem Katalysator zu senken, um dadurch die Schadstoffemissionen generell senken zu können.In an advantageous development of the solution according to the invention, the housing is constructed in two parts, wherein on at least one of the two housing parts cooling contours, in particular cooling ribs are formed, which protrude into the first channel, preferably perpendicular to the flow direction. The cooling contours force a flow around them through the hot exhaust gas and due to their large surface an intensive heat exchange. To increase the cooling effect, the cooling contours may be formed hollow and flowed through by a cooling fluid. The cooling fluid can, for example, from a cooling circuit, which also cools the engine, are removed, so that with the hot exhaust, for example. A warm-up of the engine significantly shortened and thereby the high NO x emissions can be reduced in particular at this stage. In general, such cooling devices can also be used for heating a passenger compartment, with the main focus being on reducing the exhaust-gas temperature before supplying it to a catalytic converter in order to be able to generally reduce pollutant emissions.
