Description

Die vorliegende Erfindung betrifft einen Stapelscheiben-Wärmeübertrager gemäß dem Oberbegriff des Anspruchs 1. Ein solcher Wärmeübertrager ist aus der DE-A-102011078136 bekannt. Die Erfindung betrifft außerdem eine Brennkraftmaschine mit einem solchen Stapelscheiben-Wärmeübertrager.
Aus der DE 10 2005 044 291 A1 ist ein gattungsgemäßer Stapelscheiben-Wärmeübertrager, insbesondere einen Ladeluftkühler, mit mehreren, aufeinander gestapelten und miteinander verbundenen, insbesondere verlöteten, länglichen Scheiben bekannt, die einen Hohlraum zum Durchführen eines zu kühlenden Mediums, beispielsweise Ladeluft, in Längsrichtung der Scheiben und einen weiteren Hohlraum zum Durchführen eines Kühlmittels begrenzen. Die Scheiben weisen dabei jeweils einen Eingangsanschluss und einen Ausgangsanschluss für das zu kühlende Medium auf. Um den Stapelscheiben-Wärmeübertrager kostengünstig herstellen und insbesondere langlebig in Bezug auf hohe Temperaturen ausbilden zu können, erstreckt sich mindestens ein Kühlmittelanschluss teilweise um einen Anschluss für das zu kühlende Medium herum.
Generell besteht bei gattungsgemäßen Stapelscheiben-Wärmeübertragern stets das Problem, dass diese einseitig über ihre Grundplatte weit auskragend an beispielsweise einer Brennkraftmaschine angebunden sind, wodurch aufgrund der einseitigen Anbindung und der großen Kragweite große Schwingungen über die Grundplatte abgetragen werden müssen, wodurch die Grundplatten selbst vergleichsweise schwer und damit auch teuer ausgebildet werden müssen. Je größer dabei die gewünschte Leistung des Stapelscheiben-Wärmeübertragers ist, umso mehr Stapelscheiben muss dieser aufweisen und umso stärker muss die zugehörige Grundplatte ausgelegt werden.
Die vorliegende Erfindung beschäftigt sich mit daher mit dem Problem, für einen Stapelscheiben-Wärmeübertrager der gattungsgemäßen Art eine verbesserte oder zumindest eine alternative Ausführungsform anzugeben, welche insbesondere hinsichtlich auftretender Schwingungen eine verbesserte Anbindung ermöglicht.
Dieses Problem wird erfindungsgemäß durch den Gegenstand des unabhängigen Anspruchs gelöst. Vorteilhafte Ausführungsformen sind Gegenstand der abhängigen Ansprüche.
Die vorliegender Erfindung beruht auf dem allgemeinen Gedanken, einen Stapelscheiben-Wärmeübertrager nicht mehr wie bislang aus dem Stand der Technik bekannt, in der Art eines Kragarms ausschließlich an einem Längsende zu lagern und dadurch große Schwingungen aufnehmen zu müssen, sondern eine Lagerung über eine Verteilerplatte bzw. zwei Grundplatten zu realisieren, die zentral, insbesondere mittig des Stapelscheiben-Wärmeübertragers angeordnet ist/sind. Der erfindungsgemäße Stapelscheiben-Wärmeübertrager, welcher beispielsweise als Ladeluftkühler einer Brennkraftmaschine ausgebildet sein kann, weist dabei ein erstes und ein zweites Stapelscheibenpaket mit jeweils mehreren, aneinander gereihten und miteinander verbundenen, insbesondere verlöteten, Stapelscheiben und eine Grundplatte auf, über welche eine Zu- und/oder eine Abführung eines Kühlmittels erfolgt. Die beiden Stapelscheibenpakete sind dabei direkt über ihre Grundplatten miteinander und mit einem Kühlmitteleinlass und/oder einem Kühlmittelauslass verbunden. Darüber hinaus erfolgt die Halterung des Stapelscheiben-Wärmeübertragers über einen Halter, der mit den beiden zentral angeordneten Grundplatten verbunden ist. Hierdurch kann eine mittige Lagerung des erfindungsgemäßen Stapelscheiben-Wärmeübertragers erreicht werden, wodurch die einzelnen Stapelscheibenpakete nicht mehr so weit auskragen und dadurch im Betrieb der Brennkraftmaschine auch nicht mehr so stark schwingen, wodurch prinzipiell auch die beiden Grundplatten selbst dünner ausgebildet werden können. Bei dem erfindungsgemäßen Stapelscheiben-Wärmeübertrager wird somit erstmals eine mittige Lagerung geschaffen, was erhebliche Vorteile hinsichtlich des Schwingungsverhaltens und auch hinsichtlich der Auslegung der Grundplatte bzw. der Grundplatten des Stapelscheiben-Wärmeübertragers ermöglicht.
Bei einer vorteilhaften Weiterbildung der erfindungsgemäßen Lösung sind das erste Stapelscheibenpaket als Hochtemperaturkühler und das zweite Stapelscheibenpaket als Niedertemperaturkühler ausgebildet. Hierdurch kann beispielsweise ein Ladeluftstrom für eine Brennkraftmaschine effektiv gekühlt werden, indem dieser zunächst durch das als Hochtemperaturkühler ausgebildete erste Stapelscheibenpaket, anschließend durch dessen Grundplatte, und die Grundplatte des zweiten Stapelscheibenpakets sowie dann durch das als Niedertemperaturkühler ausgebildete zweite Stapelscheibenpaket geleitet wird. Mit dem erfindungsgemäßen Stapelscheiben-Wärmeübertrager ist somit auch eine vergleichsweise einfache Kopplung eines Hochtemperaturkühlers mit einem Niedertemperaturkühler möglich.The present invention relates to a stacked plate heat exchanger according to the preamble of claim 1. Such a heat exchanger is known from DE-A-102011078136 known. The invention also relates to an internal combustion engine with such a stacked plate heat exchanger.
From the DE 10 2005 044 291 A1 is a generic stacked plate heat exchanger, in particular a charge air cooler, with a plurality of stacked and interconnected, in particular soldered, elongated discs known having a cavity for passing a medium to be cooled, for example, charge air, in the longitudinal direction of the discs and another cavity for performing of a coolant limit. The discs each have an input port and an output port for the medium to be cooled. In order to produce the stacked plate heat exchanger inexpensively and in particular to be able to develop a long service life with respect to high temperatures, at least one coolant connection partially extends around a connection for the medium to be cooled.
Generally, generic stack-top heat exchangers always have the problem that they are connected on one side over their base plate cantilevered example of an internal combustion engine, which due to the unilateral connection and the large Kragweite large vibrations on the base plate must be removed, making the base plates themselves comparatively difficult and thus have to be trained expensive. The greater the desired performance of the stacked plate heat exchanger, the more stacking disks this must have and the more the corresponding base plate must be designed.
The present invention therefore deals with the problem of providing for a stacked plate heat exchanger of the generic type an improved or at least one alternative embodiment, which allows in particular with regard to vibrations occurring improved connection.
This problem is solved according to the invention by the subject matter of the independent claim. Advantageous embodiments are the subject of the dependent claims.
The present invention is based on the general idea not to store a stacked plate heat exchanger as previously known from the prior art, in the manner of a cantilever exclusively at one longitudinal end and thereby absorb large vibrations, but a storage on a distributor plate or .2 to realize two base plates, which is arranged centrally, in particular centrally of the stacked plate heat exchanger / are. The stacked-plate heat exchanger according to the invention, which may be designed, for example, as an intercooler of an internal combustion engine, has a first and a second stacking disk package, each with a plurality of stacked and interconnected, in particular soldered, stacking disks and a base plate, via which a supply and / or or a discharge of a coolant takes place. The two stacking disk packages are connected directly via their base plates with each other and with a coolant inlet and / or a coolant outlet. In addition, the holder of the stacked plate heat exchanger via a holder which is connected to the two centrally arranged base plates. As a result, a central storage of the stacked-plate heat exchanger according to the invention can be achieved, as a result of which the individual stacking disk packs no longer protrude so far and therefore do not swing so strongly during operation of the internal combustion engine, as a result of which in principle the two base plates themselves can also be made thinner. In the stacked-plate heat exchanger according to the invention a central storage is thus created for the first time, which allows significant advantages in terms of vibration behavior and also in terms of the design of the base plate and the base plates of the stacked plate heat exchanger.
In an advantageous development of the solution according to the invention, the first stacking disk pack is designed as a high-temperature cooler and the second stacking disk pack as a low-temperature cooler. In this way, for example, a charge air flow for an internal combustion engine can be effectively cooled by this is first passed through the designed as a high-temperature radiator stack stacking package, then through the base plate, and the base plate of the second stacking disk package and then designed as a low-temperature radiator second stacking disk package. With the stacked-plate heat exchanger according to the invention thus also a comparatively simple coupling of a high-temperature cooler with a low-temperature cooler is possible.

Bei einer weiteren vorteilhaften Ausführungsform der erfindungsgemäßen Lösung weist das erste und das zweite Stapelscheibenpaket jeweils eine Deckscheibe mit einem Durchgang für das zu kühlende Medium, insbesondere für zu kühlendes Abgas, auf. In diesem Fall wird somit der Stapelscheiben-Wärmeübertrager orthogonal den Stapelscheibenebenen vom zu kühlenden Medium durchflossen, wobei selbstverständlich im ersten Stapelscheibenpaket und/oder im zweiten Stapelscheibenpaket auch eine Umlenkung des zu kühlenden Mediums, beispielsweise des zu kühlenden Abgases parallel zu den jeweiligen Stapelscheiben möglich ist.
Bei einer weiteren vorteilhaften Ausführungsform der erfindungsgemäßen Lösung sind/ist die Stapelscheiben, die Grundplatten aus lötbarem Aluminium ausgebildet. Aluminium besitzt einen vergleichsweise hohen Wärmeleitkoeffizient und ist zudem vergleichsweise leicht, wodurch es für den Einsatz eines Ladeluftkühlers in einer Brennkraftmaschine eines Kraftfahrzeugs besonders vorteilhaft ist.In a further advantageous embodiment of the solution according to the invention, the first and the second stacking disk pack each have a cover disk with a passage for the medium to be cooled, in particular for exhaust gas to be cooled. In this case, therefore, the stacked plate heat exchanger is orthogonally through the stacked disk planes to be cooled medium, which of course in the first stacking disk package and / or in the second stacking disk package, a deflection of the medium to be cooled, for example, to be cooled exhaust gas parallel to the respective stacking disks is possible.
In a further advantageous embodiment of the solution according to the invention are / is the stacking disks, the base plates formed of solderable aluminum. Aluminum has a comparatively high thermal conductivity coefficient and is also comparatively light, which makes it suitable for the use of a Charge air cooler in an internal combustion engine of a motor vehicle is particularly advantageous.

Die vorliegende Erfindung beruht weiter auf dem allgemeinen Gedanken, bei einer Brennkraftmaschine einen zuvor beschriebenen Stapelscheiben-Wärmeübertrager als Ladeluftkühler einzusetzen, wodurch insbesondere eine schwingungsoptimierte Anbindung des Stapelscheiben-Wärmeübertragers ermöglicht wird.The present invention is further based on the general idea to use a previously described stacked plate heat exchanger as a charge air cooler in an internal combustion engine, which in particular a vibration-optimized connection of the stacked plate heat exchanger is made possible.

Entsprechend den Fig. 1-3 weist ein erfindungsgemäßer Stapelscheiben-Wärmeübertrager 1, der insbesondere als Ladeluftkühler einer Brennkraftmaschine 2 in einem Kraftfahrzeug 3 ausgebildet sein kann, ein erstes Stapelscheibenpaket 4 sowie ein zweites Stapelscheibenpaket 5 mit jeweils mehreren, aneinander gereihten und miteinander verbundenen, insbesondere miteinander verlöteten, Stapelscheiben 6 sowie jeweils einer Grundplatte 7 auf, über welche eine Zu- und/oder Abführung eines Kühlmittels 8 erfolgt. Nicht erfindungsgemäß können nun die beiden Stapelscheibenpakete 4, 5 über eine zwischen den beiden Grundplatten 7 liegende Verteilerplatte 9 (vergleiche die Fig. 6 und 7) miteinander und mit einem Kühlmitteleinlass 10 und/oder einem Kühlmittelauslass 11 verbunden werden. Erfindungsgemäß sind die beiden Stapelscheibenpakete 4, 5 über ihre jeweilige Grundplatte 7 miteinander verbunden, wobei diese beiden Grundplatten 7 dann zusammen eine Verteilerplatte 9 bilden und ebenfalls einen Kühlmitteleinlass 10 und/oder einen Kühlmittelauslass aufweisen. Darüber hinaus ist ein Halter 12 vorgesehen, der den Stapelscheiben-Wärmeübertrager 1 ausschließlich mittig, das heißt an den beiden Grundplatten bzw. nicht erfindungsgemäß an der Verteilerplatte 9 hält und dadurch das jeweils von der Grundplatte 7 auskragende Stapelscheibenpaket 4, 5 zentral fixiert. Hierdurch können im Vergleich zu einem aus dem Stand der Technik bekannten Stapelscheiben-Wärmeübertrager, bei welchem das gesamte Stapelscheibenpaket lediglich einseitig in der Art eines Kragarmes an einer Grundplatte aufgehängt ist, deutlich geringere Schwingungsbelastungen aufgrund der kürzeren erfindungsgemäßen Stapelscheibenpakete 4, 5 erzielt werden, wodurch zum einen sowohl die Grundplatten 7 beispielsweise weniger steif und damit auch weniger schwer ausgebildet werden müssen und zudem externe Rohrleitungen, welche bei einer einseitigen Anbindung oftmals erforderlich waren, vermieden werden können.
Betrachtet man beispielsweise die Stapelscheiben-Wärmeübertrager 1 gemäß der Fig. 6, so ist dort erkennbar, dass das erste Stapelscheibenpaket 4 als Hochtemperaturkühler (HT) und das zweite Stapelscheibenpaket 5 als Niedertemperaturkühler (LT) ausgebildet ist.According to the Fig. 1-3 has a stacked-plate heat exchanger 1 according to the invention, which may be formed in particular as intercooler of an internal combustion engine 2 in a motor vehicle 3, a first stacking disk package 4 and a second stacking disk package 5, each with a plurality of juxtaposed and interconnected, in particular soldered to each other, stacking disks 6 and respectively a base plate 7, via which a supply and / or discharge of a coolant 8 takes place. Not according to the invention can now the two stacking disk packages 4, 5 via a lying between the two base plates 7 distribution plate 9 (see the Fig. 6 and 7) are connected to each other and to a coolant inlet 10 and / or a coolant outlet 11. According to the invention, the two stacking disk packages 4, 5 are interconnected via their respective base plate 7, these two base plates 7 then together forming a distributor plate 9 and also having a coolant inlet 10 and / or a coolant outlet. In addition, a holder 12 is provided, which holds the stacking plate heat exchanger 1 exclusively in the center, that is on the two base plates or not according to the invention on the distributor plate 9 and thereby centrally fixed each projecting from the base plate 7 stacking disc package 4, 5. In this way, compared to a known from the prior art stacking plate heat exchanger, in which the entire stacking disk package is suspended only on one side in the manner of a cantilever to a base plate, clearly lower vibration loads due to the shorter invention Stacking disk packages 4, 5 are achieved, whereby both the base plates 7, for example, less rigid and thus less difficult to be formed and also external piping, which were often required in a one-sided connection, can be avoided on the one hand.
Consider, for example, the stacked plate heat exchanger 1 according to the Fig. 6 , it can be seen there that the first stacking disk package 4 is designed as a high-temperature cooler (HT) and the second stacking disk package 5 as a low-temperature cooler (LT).

In der Verteilerplatte 9 bzw. den beiden, diese Verteilerplatte 9 bildenden Grundplatten 7 kann dabei beispielsweise sowohl ein Kühlmitteleinlass 10 und ein Kühlmittelauslass 11 für das erste Stapelscheibenpaket 4 als auch ein Kühlmitteleinlass 10 und ein Kühlmittelauslass 11 für das zweite Stapelscheibenpaket 5 vorgesehen sein (vergleiche die Fig. 6). Alternativ hierzu kann auch vorgesehen sein, dass in der Verteilerplatte 9 bzw. in den beiden diese Verteilerplatte 9 bildenden Kühlplatten 7 sowohl ein Kühlmitteleinlass 10 oder ein Kühlmittelauslass 11 für das erste Stapelscheibenpaket 4 als auch ein Kühlmitteleinlass 10 oder ein Kühlmittelauslass 11 für das zweite Stapelscheibenpaket 5 vorgesehen sind. In der Verteilerplatte 9 bzw. den beiden Grundplatten 7 kann alternativ ebenso auch ein Kühlmitteleinlass 10 für das erste Stapelscheibenpaket 4 und ein Kühlmittelauslass 11 für das zweite Stapelscheibenpaket 5 oder umgekehrt vorgesehen sein. In der Verteilerplatte 9 bzw. in den beiden Grundplatten 7 sind dabei nicht näher bezeichnete Kanäle für ein zu kühlendes Medium 13, beispielsweise Abgas 14, und für Kühlmittel 8 angeordnet sein.In this case, both a coolant inlet 10 and a coolant outlet 11 for the first stacking disk package 4 as well as a coolant inlet 10 and a coolant outlet 11 for the second stacking disk package 5 can be provided in the distributor plate 9 or the two base plates 7 forming this distributor plate 9 (cf. Fig. 6 ). Alternatively, it can also be provided that both a coolant inlet 10 or a coolant outlet 11 for the first stacking disk package 4 and a coolant inlet 10 or a coolant outlet 11 for the second stacking disk package 5 are provided in the distributor plate 9 or in the two cooling plates 7 forming this distributor plate 9 are provided. Alternatively, a coolant inlet 10 for the first stacking-disk package 4 and a coolant outlet 11 for the second stacking-disk package 5 or vice versa can likewise be provided in the distributor plate 9 or the two base plates 7. In the distributor plate 9 and in the two base plates 7 are unspecified channels for a medium to be cooled 13, for example, exhaust 14, and be arranged for coolant 8.

Betrachtet die Ausführungsformen gemäß den Fig. 1-4 und 6, so kann man des Weiteren erkennen, dass das erste und zweite Stapelscheibenpaket 4, 5 jeweils eine Deckscheibe 15 mit einem Durchgang 16 für das zu kühlende Medium 13, insbesondere für das zu kühlende Abgas 14 aufweist. Die Stapelscheiben 6 selbst bzw. die Grundplatten 7 und/oder die Verteilerplatte 9 können dabei aus einem leichten und zugleich gut wärmeleitenden Material, wie beispielsweise lötbarem Aluminium, ausgebildet sein.
Eine mit dem erfindungsgemäßen Stapelscheiben-Wärmeübertrager 1 ausgestattete Brennkraftmaschine 2 eines Kraftfahrzeuges 3 bietet den großen Vorteil, dass eine schwingungsoptimierte Lagerung möglich ist, da das ursprünglich einteilige Stapelscheibenpaket nunmehr in zwei Stapelscheibe 4, 5 aufgeteilt wurde und dadurch der jeweils auskragende Teil des Stapelscheibenpakets 4, 5 nur noch circa halb so groß ist wie bei den aus dem Stand der Technik bekannten, einseitig angebundenen Stapelscheibenpaketen. Hierdurch können insbesondere auch die Grundplatten 7 bzw. nicht erfindungsgemäß die Verteilerplatte 9 leichter und damit kostengünstiger ausgelegt werden. Die beiden Stapelscheibenpakete 4, 5 können dabei im Wesentlichen gleich groß sein oder aber auch eine unterschiedliche Größe aufweisen, insbesondere sofern beispielsweise ein Hochtemperaturkühler eine höhere oder niedrigere Leistung als ein nachgeschalteter Niedertemperaturkühler aufweisen soll. Eine Verbindung zwischen den beiden Grundplatten bzw. nicht erfindungsgemäß zwischen diesen und der Verteilerplatte 9 wird beispielsweise mittels Schrauben 17 (vergleiche Fig. 6) bewirkt.
Um eine möglichst steife Anbindung des Stapelscheiben-Wärmeübertragers 1 an die Brennkraftmaschine 2 erreichen zu können, kann der hierfür genutzte Halter 12 Versteifungsrippen 18 aufweisen (vergleiche die Fig. 1-5), wobei der Halter 12 mit dem Stapelscheiben-Wärmeübertrager 1 verschraubt sein kann. Rein theoretisch ist selbst eine Führung einer Kühlmittelleitung innerhalb des Halters 12 denkbar.Consider the embodiments according to FIGS Fig. 1-4 and 6 , it can be further seen that the first and second stacking disk package 4, 5 each have a cover plate 15 with a passage 16 for the medium to be cooled 13, in particular for the exhaust gas 14 to be cooled. The stacking disks 6 themselves or the base plates 7 and / or the distributor plate 9 can be made of a light and at the same time good heat conducting material, such as solderable aluminum, be formed.
An equipped with the stacked-plate heat exchanger 1 internal combustion engine 2 of a motor vehicle 3 offers the great advantage that a vibration-optimized storage is possible because the originally one-piece stacking disk package has now been divided into two stacking disk 4, 5 and thereby the respective projecting part of the stacking disk package 4, 5 is only about half as large as in the known from the prior art, unilaterally connected stacking disk packages. As a result, in particular, the base plates 7 and not according to the invention the distributor plate 9 can be designed to be lighter and thus more cost-effective. The two stacking disk packages 4, 5 may be substantially the same size or have a different size, in particular if, for example, a high-temperature cooler should have a higher or lower power than a downstream low-temperature cooler. A connection between the two base plates or not according to the invention between these and the distributor plate 9 is, for example by means of screws 17 (see Fig. 6 ) causes.
In order to achieve the most rigid connection possible of the stacked plate heat exchanger 1 to the internal combustion engine 2, the holder 12 used for this purpose can have stiffening ribs 18 (compare FIGS Fig. 1-5 ), wherein the holder 12 may be bolted to the stacked plate heat exchanger 1. In theory, even a guide of a coolant line within the holder 12 is conceivable.
