Description
TECHNISCHES GEBIETTECHNICAL AREA
Die Erfindung betrifft einen Abgaskühler.The invention relates to an exhaust gas cooler.
Insbesondere bei der Rückführung von Abgas auf die Frischluftseite eines Verbrennungsmotors ist es in bestimmten Situationen unerwünscht, das Abgas zu kühlen. Hierfür wird das Abgas durch ein Bypassrohr geführt, das nicht oder nicht im gleichen Umfang gekühlt wird wie die eigentliche Abgasrückführleitung.In particular, in the return of exhaust gas to the fresh air side of an internal combustion engine, it is undesirable in certain situations to cool the exhaust gas. For this purpose, the exhaust gas is passed through a bypass pipe, which is not or not cooled to the same extent as the actual exhaust gas recirculation line.
Hierbei werden zwei Bauarten unterschieden. Einerseits kann sich das Bypassrohr innerhalb des Kühlergehäuses befinden und somit von Kühlmittel umströmt sein. Dies bietet Vorteile dahingehend, dass das Bypassrohr im Wesentlichen keinen Temperaturunterschied zu denjenigen Bauteilen aufweist, zwischen denen es befestigt ist, und somit Spannungen infolge von Temperaturunterschieden vermieden werden. Es kommt jedoch, wenngleich das Bypassrohr üblicherweise kürzer ist als die eigentliche Abgasrückführleitung im Bereich des Abgaskühlers, immer noch zu einer Kühlung des Abgases, was nachteilig ist. Der wesentliche Nachteil besteht darin, dass auch bei Durchströmung des Bypassrohres ein Wärmeübergang stattfindet, der vermieden werden sollte, obwohl er geringer ist als in dem Fall, wenn die Kühlrohre durchströmt werden. Here, two types are distinguished. On the one hand, the bypass tube can be located inside the radiator housing and thus flow around coolant. This offers advantages in that the bypass tube has substantially no temperature difference to those components between which it is attached, and thus stresses due to temperature differences are avoided. However, although the bypass pipe is usually shorter than the actual exhaust gas recirculation line in the region of the exhaust gas cooler, cooling of the exhaust gas still occurs, which is disadvantageous. The main disadvantage is that even when flowing through the bypass tube heat transfer takes place, which should be avoided, although it is less than in the case when the cooling tubes are flowed through.
Dies wird bei Bypassrohren vermieden, die außerhalb des mit Kühlmittel gefüllten Kühlergehäuses geführt werden. Hierbei kommt es jedoch zu Spannungen infolge erheblicher Temperaturunterschiede zwischen der Temperatur des Bypassrohres und derjenigen der Verbindungen des Bypassrohres zu umgebenden Bauteilen.This is avoided with bypass tubes routed outside the radiator housing filled with coolant. In this case, however, there are tensions due to significant temperature differences between the temperature of the bypass tube and those of the compounds of the bypass tube to surrounding components.
STAND DER TECHNIKSTATE OF THE ART
Zur Lösung der genannten Probleme bei außerhalb des Kühlergehäuses geführten Bypassrohren ist es bekannt, ein oder mehrere vorhandene Bypassrohre mit einem metallenen Faltenbalg zu versehen, der jedoch zusätzlichen Platzbedarf aufweist, und vergleichsweise kostenintensiv hergestellt werden muss. Ferner sind derartige metallene Faltenbalge nur für kreisförmige Querschnitte erhältlich, so dass der verfügbare Bauraum auch bei Verwendung mehrerer Rohre mit kreisförmigem Querschnitt nicht optimal genutzt werden kann.To solve the problems mentioned in outside of the cooler housing guided bypass tubes, it is known to provide one or more existing bypass tubes with a metal bellows, but which has additional space, and must be made relatively expensive. Furthermore, such metal bellows are available only for circular cross-sections, so that the available space can not be optimally used even when using multiple tubes with a circular cross-section.
Der Vollständigkeit halber sei erwähnt, dass aus der
DARSTELLUNG DER ERFINDUNGPRESENTATION OF THE INVENTION
Vor diesem Hintergrund liegt der Erfindung die Aufgabe zugrunde, einen Abgaskühler zu schaffen, der im Hinblick auf die Kosten und/oder die Effizienz gegenüber dem Stand der Technik verbessert ist.Against this background, the invention has for its object to provide an exhaust gas cooler, which is improved in terms of cost and / or efficiency over the prior art.
Die Lösung dieser Aufgabe erfolgt durch den im Patenanspruch 1 beschriebenen Abgaskühler.The solution to this problem is achieved by the exhaust gas cooler described in claim 1.
Demzufolge weist dieser zumindest ein Bypassrohr auf, das außerhalb eines von einem Kühlmittel durchströmten Raumes verläuft, so dass eine unerwünschte Kühlung des durch den Bypass geführten Abgases weitestgehend unterbleibt. Zur Kompensation der infolge der Temperaturunterschiede auftretenden thermischen Spannungen weist zumindest ein Bypassrohr in seinem Verlauf, mit anderen Worten von jeglichen Anbringstellen entfernt, zumindest eine Nut auf, die eine Verformung des Bypassrohres in dessen axialer Richtung erlaubt. Eine derartige Nut ist günstiger herstellbar als ein metallener Faltenbalg und benötigt weniger Bauraum. Der Grund dafür liegt darin, dass die Nut üblicherweise eine maximale Tiefe aufweist, die der Wanddicke des Bypassrohres entspricht, so dass selbst dann, wenn die Nut an der Rohrinnenseite ausgebildet ist und demnach an der Außenseite ein Vorsprung ausgebildet wird, der Durchmesser des Rohres nur geringfügig vergrößert wird, und im Wesentlichen kein zusätzlicher Bauraum benötigt wird. Darüber hinaus wird für die beschriebene Nut erwartet, dass sie infolge der Temperaturveränderungen auftretende Dehnungen und Stauchungen des Bypassrohres ohne Auftreten von übermäßigen Spannungen ermöglicht, so dass für eine vorteilhafte Kompensation der im Vergleich zu umgebenden Bauteilen unterschiedlichen Dehnung oder Stauchung gesorgt wird.Accordingly, this has at least one bypass tube, which runs outside of a space flowed through by a coolant, so that an undesired cooling of the exhaust gas guided through the bypass largely disappears. To compensate for the thermal stresses occurring as a result of the temperature differences, at least one bypass tube in its course, in other words away from any attachment points, at least one groove which allows deformation of the bypass tube in its axial direction. Such a groove is cheaper to produce than a metal bellows and requires less space. The reason for this is that the groove usually has a maximum depth corresponding to the wall thickness of the bypass pipe, so that even if the groove is formed on the pipe inside and thus on the outside of a projection is formed, the diameter of the pipe only is slightly increased, and essentially no additional space is needed. In addition, it is expected for the groove described that it allows due to the temperature changes occurring strains and compressions of the bypass tube without the occurrence of excessive stresses, so that is provided for an advantageous compensation of the difference compared to surrounding components different strain or compression.
Vorteilhafte Weiterbildungen des erfindungsgemäßen Abgaskühlers sind in den weiteren Ansprüchen beschrieben.Advantageous developments of the exhaust gas cooler according to the invention are described in the further claims.
Der verfügbare Bauraum kann besonders gut genutzt werden, wenn zumindest ein Bypassrohr einen ovalen Querschnitt aufweist. Dieser kann elliptisch sein, oder, im Querschnitt gesehen, zueinander parallele Wände aufweisen, die an den Seiten durch Halbkreise verbunden werden. Durch die erfindungsgemäße Nut kann in vorteilhafter Weise ein Bypassrohr mit ovalem Querschnitt genutzt werden und die beschriebene Kompensation von Spannungen erreicht werden, ohne dass hierfür eigens ein geeigneter metallener Faltenbalg vorgesehen werden muss.The available space can be used particularly well if at least one bypass tube has an oval cross-section. This may be elliptical, or seen in cross-section, have mutually parallel walls, which are connected at the sides by semicircles. By virtue of the groove according to the invention, a bypass tube with an oval cross-section can be used in an advantageous manner, and the described compensation of stresses can be achieved without the need for a suitable metallic bellows for this purpose.
Wenngleich es für die erfindungsgemäßen Nuten denkbar ist, dass sie sich ringförmig entlang des Außen- und/oder Innenumfangs des Bypassrohres erstrecken, und wenngleich mehrere derartiger Nuten vorgesehen werden können, wird derzeit bevorzugt, zumindest eine durchgehende, spiralförmige Nut vorzusehen. Die Steigung der Nut kann beispielsweise 5-10 mm betragen. Bevorzugt ist die Steigung etwa zwei bis drei Mal so groß wie eine Breite der Nut in Axialrichtung des Rohres und somit in einem Längsschnitt erkennbar. Gleiches gilt für den Abstand zwischen zwei oder mehr ringförmigen Nuten bezogen auf den Abstand zwischen den jeweiligen Mitten der Nuten.Although it is conceivable for the grooves according to the invention that they extend annularly along the outer and / or inner circumference of the bypass tube, and although several such Grooves can be provided is currently preferred to provide at least one continuous, spiral groove. The slope of the groove may be for example 5-10 mm. Preferably, the slope is about two to three times as large as a width of the groove in the axial direction of the tube and thus recognizable in a longitudinal section. The same applies to the distance between two or more annular grooves with respect to the distance between the respective centers of the grooves.
Derzeit wird ferner bevorzugt, dass die Nut an der Außenseite ausgebildet wird, da hierdurch der notwendige Bauraum nicht vergrößert wird.At present, it is further preferred that the groove is formed on the outside, as this does not increase the necessary space.
Für das Bypassrohr werden ferner gute Eigenschaften erwartet, wenn es eine Wanddicke von etwa 0,5 mm bis 1,0 mm aufweist. Insbesondere können bei einer derartigen Wanddicke die erfindungsgemäße(n) Nut(en) kostengünstig ausgebildet werden.Good properties are also expected for the bypass tube if it has a wall thickness of about 0.5 mm to 1.0 mm. In particular, with such a wall thickness, the groove (s) according to the invention can be formed inexpensively.
Im Hinblick auf den Durchmesser, im Fall eines ovalen Querschnitts für den größten Durchmesser des Bypassrohres werden derart 30 mm bis 60 mm bevorzugt. Der kleinere Durchmesser eines ovalen Querschnitts kann 10 bis 30 mm betragen.With respect to the diameter, in the case of an oval cross-section for the largest diameter of the bypass tube 30 mm to 60 mm are preferred. The smaller diameter of an oval cross section may be 10 to 30 mm.
Entsprechend der oben bereits erwähnten Ausgestaltung wird für zumindest eine Nut eine Tiefe von 0,5 mm bis 0,8 mm bevorzugt. Diese Tiefe ist bevorzugt allenfalls gleich groß wie die Wanddicke. Dies bedeutet weiterhin einen Unterschied zu einem Faltenbalg einschließlich eines wesentlich geringeren Platzbedarfes, da die „Wellen“ eines Faltenbalgs, im Querschnitt gesehen, eine Höhe in der Größenordnung eines Vielfachen der Wanddicke aufweisen.According to the embodiment already mentioned above, a depth of 0.5 mm to 0.8 mm is preferred for at least one groove. This depth is preferably at most the same size as the wall thickness. This also means a difference to a bellows including a much smaller footprint, since the "waves" of a bellows, seen in cross section, have a height in the order of a multiple of the wall thickness.
Bevorzugt wird der von dem Kühlmittel durchströmte Raum von einem Gehäuse umschlossen, so dass eine besonders gute Abgrenzung, insbesondere im Hinblick auf eine unerwünschte Wärmeübertragung, zu dem oder den Bybassrohr(en) erreicht wird. Somit kann insbesondere in dem Fall, dass das eine oder mehrere Bypassrohr(e) von Abgas durchströmt wird, eine unerwünschte Kühlung des Abgases vermieden werden. Es sei erwähnt, dass das Gehäuse auch als Hülle oder Schale oder in Englisch als Shell bezeichnet werden kann.The space through which the coolant flows is preferably enclosed by a housing, so that a particularly good delimitation, in particular with regard to undesired heat transfer, to the bypass pipe (s) is achieved. Thus, in particular in the case that the one or more bypass pipe (s) is traversed by exhaust gas, an undesirable cooling of the exhaust gas can be avoided. It should be noted that the housing may also be referred to as a shell or shell or in English as a shell.
Insbesondere um den erfindungsgemäßen Abgaskühler mit einem externen, also außerhalb des vom Kühlmittel durchströmten Gehäuses verlaufenden Bypassrohr effizient handhaben zu können, wird ferner bevorzugt, dass das oben beschriebene Gehäuse und das zumindest eine Bypassrohr durch zumindest einen gemeinsamen Flansch gehalten werden. Bevorzugt ist an beiden Enden jeweils ein Flansch vorgesehen, der die notwendigen Rohre, Gehäuse etc. hält, und darüber hinaus mit geeigneten Konturen, beispielsweise Befestigungsöffnungen zur Verbindung mit umgebenden Bauteilen versehen ist. Der Flansch kann auch als Verbindungsplatte bezeichnet werden.In particular, in order to be able to efficiently handle the exhaust gas cooler according to the invention with an external bypass pipe running outside of the coolant flow, it is further preferred that the housing described above and the at least one bypass pipe be held by at least one common flange. Preferably, a flange is provided at both ends, which holds the necessary pipes, housing, etc., and is also provided with suitable contours, for example mounting holes for connection to surrounding components. The flange can also be referred to as a connection plate.
