Description
Die vorliegende Erfindung betrifft einen Stapelscheibenwärmeübertrager zur Wärmeübertragung zwischen einem ersten Fluid und einem zweiten Fluid, mit den Merkmalen des Oberbegriffs des Anspruchs 1.The present invention relates to a stacked disk heat exchanger for heat transfer between a first fluid and a second fluid, having the features of the preamble of claim 1.
Aus der
Um einen derartigen Stapelscheibenwärmeübertrager möglichst preiswert herstellen zu können, ist es grundsätzlich möglich, die Hauptscheiben als identische Gleichteile herzustellen und so auszugestalten, dass sie um eine parallel zur Stapelrichtung verlaufende Längsmittelachse des Stapels jeweils um 180° verdreht aufeinander stapelbar sind, um die beiden Fluidpfade für das erste Fluid und das zweite Fluid innerhalb des Stapels auszubilden. Bei identischen Hauptplatten ergeben sich dann auch identische Strömungspfade für das erste und zweite Fluid.To be able to produce such a stacked-plate heat exchanger as inexpensively as possible, it is basically possible to produce the main disks as identical identical parts and to design them so that they can be stacked around a parallel to the stacking direction longitudinal central axis of the stack each rotated by 180 ° to each other to the two fluid paths for forming the first fluid and the second fluid within the stack. With identical main plates then arise identical flow paths for the first and second fluid.
Bei bestimmten Einsatzfällen derartiger Stapelscheibenwärmeübertrager kann jedoch die Wärmeabgabekapazität des einen Fluids deutlich unterschiedlich sein zur Wärmeaufnahmekapazität des anderen Fluids. Dies kann beispielsweise durch unterschiedliche Volumenströme und/oder verschiedene Wärmeleitkoeffizienten innerhalb der beiden Fluide verursacht sein. Es besteht daher der Bedarf, einen derartigen Stapelscheibenwärmeübertrager an unterschiedliche Fluid- und Durchströmungssituationen anpassen zu können, um den Wirkungsgrad der Wärmeübertragung zu verbessern.However, in certain applications of such stacked plate heat exchangers, the heat release capacity of one fluid may be significantly different than the heat capacity of the other fluid. This can be caused, for example, by different volume flows and / or different heat conduction coefficients within the two fluids. There is therefore a need to be able to adapt such a stacked plate heat exchanger to different fluid and Durchströmungssituationen to improve the efficiency of heat transfer.

Die vorliegende Erfindung beschäftigt sich mit dem Problem, für einen Stapelscheibenwärmeübertrager der eingangs genannten Art eine verbesserte oder zumindest eine andere Ausführungsform anzugeben, die sich insbesondere dadurch auszeichnet, dass sie mit einem vergleichsweise geringen Aufwand an unterschiedliche Strömungssituationen und/oder Fluidpaarungen anpassbar ist.The present invention is concerned with the problem of providing for a stacked plate heat exchanger of the type mentioned an improved or at least another embodiment, which is particularly characterized in that it is adaptable with a relatively low cost to different flow situations and / or fluid pairings.
Dieses Problem wird erfindungsgemäß durch den Gegenstand des unabhängigen Anspruchs gelöst. Vorteilhafte Ausführungsformen sind Gegenstand der abhängigen Ansprüche.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.
Die Erfindung beruht auf dem allgemeinen Gedanken, den Stapelscheibenwärmeübertrager mit wenigstens einer Zusatzscheibe auszustatten, die in der Stapelrichtung zwischen zwei benachbarten Hauptscheiben angeordnet ist. Die Zusatzscheibe ist dabei so ausgestaltet, dass im Stapel ein zusätzlicher Verbindungskanal (Zusatzverbindungskanal) entsteht, der nur mit einem seiner in der Stapelrichtung unmittelbar benachbarten Verbindungskanäle (Hauptverbindungskanäle) fluidisch verbunden ist. Durch diese Maßnahme wird im Bereich der Zusatzscheibe der durchströmbare Querschnitt des Zusatzverbindungskanals zum durchströmbaren Querschnitt des jeweiligen Hauptverbindungskanals hinzugefügt, so dass in diesem Bereich die Wärmeübertragung zwischen den beiden Fluiden verbessert werden kann. Bemerkenswert ist einerseits, dass es mit Hilfe derartiger Zusatzscheiben möglich ist, im jeweiligen Fluidpfad die Wärmeübertragungsleistung abhängig von der Anzahl der verwendeten Zusatzscheiben stufenweise zu vergrößern. Ferner ist es möglich, auch dem anderen Fluidpfad wenigstens eine solche Zusatzscheibe zuzuordnen, so dass auch dort die Wärmeübertragungsleistung abhängig von der Anzahl der verwendeten Zusatzscheiben stufenweise vergrößert werden kann. Somit lassen sich grundsätzlich beliebige Verhältnisse ganzer Zahlen zwischen ersten Verbindungskanälen, also der Summe aus dem ersten Fluidpfad zugeordneten Hauptverbindungskanälen und Zusatzverbindungskanälen, und zweiten Verbindungskanälen realisieren, also der Summe aus dem zweiten Fluidpfad zugeordneten Hauptverbindungskanälen und Zusatzverbindungskanälen. Bemerkenswert ist zum anderen, dass zur Realisierung einer derartigen Vielzahl an möglichen Konfigurationen grundsätzlich nur zwei verschiedene Scheibentypen erforderlich sind, nämlich die Hauptscheiben einerseits und die Zusatzscheiben andererseits. Dementsprechend kann eine Variantenbildung des hier vorgestellten Stapelscheibenwärmeübertragers besonders preiswert realisiert werden.The invention is based on the general idea of equipping the stacked disk heat exchanger with at least one additional disk, which is arranged in the stacking direction between two adjacent main disks. The additional disk is designed so that in the stack, an additional connection channel (additional connection channel) is formed, which is fluidly connected only with one of its immediately adjacent in the stacking direction connecting channels (main connection channels). As a result of this measure, in the region of the additional disk, the through-flow cross-section of the additional connecting channel is added to the flow-through cross section of the respective main connecting channel, so that the heat transfer between the two fluids can be improved in this area. It is noteworthy on the one hand, that it is possible with the help of such additional discs, in the respective fluid path, the heat transfer performance depending on the number of additional disks used to increase gradually. Furthermore, it is also possible to assign at least one additional disk to the other fluid path, so that even there the heat transfer capacity can be increased stepwise depending on the number of additional disks used. Thus, in principle, any ratios of integers between first connection channels, that is to say the sum of main connection channels and auxiliary connection channels assigned to the first fluid path, and second connection channels can be realized, ie the sum of main connection channels and additional connection channels assigned to the second fluid path. It is noteworthy, on the other hand, that basically only two different types of discs are required to realize such a large number of possible configurations, namely the main discs on the one hand and the auxiliary discs on the other hand. Accordingly, a variant of the presented here Stapelscheibenwärmeübertragers can be realized particularly inexpensive.
Bei einer bevorzugten Ausführungsform kann vorgesehen sein, dass die jeweilige Zusatzscheibe in der Stapelrichtung fluchtend zu den Hauptscheiben zwei Öffnungen für das erste Fluid und zwei Öffnungen für das zweite Fluid aufweist, wobei zwei der Öffnungen jeweils von einem Dom eingefasst sind. Dabei sind die Dome der jeweiligen Zusatzscheibe in der Stapelrichtung höher als die Dome der Hauptscheiben und/oder bezüglich einer Längsmittelachse des jeweiligen Einlasskanals oder Auslasskanals relativ zu den Domen der Hauptscheiben radial nach außen oder nach innen versetzt angeordnet. Durch die vorgeschlagene Ausgestaltung und/oder Positionierung der Dome der Zusatzscheibe ist der im Stapel mit Hilfe der Zusatzscheibe ausgebildete Zusatzverbindungskanal zum jeweiligen benachbarten Hauptverbindungskanal hinsichtlich seiner Durchströmung parallel geschaltet.In a preferred embodiment it can be provided that the respective additional disk has two openings for the first fluid and two openings for the second fluid in the stacking direction in alignment with the main disks, wherein two of the openings are each enclosed by a dome. In this case, the dome of the respective additional disk in the stacking direction are higher than the dome of the main disks and / or arranged radially outwardly or inwardly offset relative to the domes of the main disks with respect to a longitudinal central axis of the respective inlet channel or outlet channel. Due to the proposed embodiment and / or positioning of the dome of the additional disc, the additional connecting channel formed in the stack with the aid of the additional disk is connected in parallel to the respective adjacent main connecting channel in terms of its throughflow.
Bei einer anderen Ausführungsform kann der jeweilige Zusatzverbindungskanal in der Stapelrichtung im Wesentlichen gleich hoch sein wie die Hauptverbindungskanäle. Hierdurch lässt sich die Variantenbildung besonders einfach gestalten, da sich durch die Verwendung einer Zusatzscheibe der durchströmbare Querschnitt des mit dem dadurch gebildeten Zusatzverbindungskanals fluidisch gekoppelten Hauptverbindungskanals quasi verdoppeln lässt.In another embodiment, the respective auxiliary connection channel in the stacking direction may be substantially the same height as the main connection channels. As a result, the formation of variants can be made particularly simple, since the use of an additional disk allows the through-flow cross-section of the main connection channel, which is fluidically coupled to the additional connecting channel formed thereby, to be virtually doubled.
Gemäß einer vorteilhaften Ausführungsform kann die jeweilige Zusatzscheibe so im Stapel angeordnet sein, dass diejenige Hauptscheibe, die mit der jeweiligen Zusatzscheibe den Zusatzverbindungskanal in der Stapelrichtung begrenzt, im Bereich ihrer nicht von den Domen dieser Hauptscheibe eingefassten Öffnungen freistehend angeordnet ist, so dass der Zusatzverbindungskanal durch diese Öffnungen mit dem benachbarten Hauptverbindungskanal fluidisch verbunden ist. Auf diese Weise wird innerhalb des Stapels ein interner Bypass geschaffen, durch den das jeweilige Fluid zusätzlich, also parallel zum zugehörigen Hauptverbindungskanal hindurchströmen kann.According to an advantageous embodiment, the respective additional disc may be arranged in the stack that the one main disc, which limits the additional connecting channel in the stacking direction with the respective additional disc is arranged free-standing in the area of their not enclosed by the domes of this main disc openings, so that the additional connection channel through these openings are fluidly connected to the adjacent main connection channel. In this way, an internal bypass is created within the stack, through which the respective fluid in addition, so it can flow parallel to the associated main connection channel.
Bei einer anderen Ausführungsform können die Dome der jeweiligen Zusatzscheibe so dimensioniert und angeordnet sein, dass sie in die Dome einer der benachbarten Hauptscheiben eingreifen. Somit gliedern sich die Dome der jeweiligen Zusatzscheibe in die Ausbildung des jeweiligen Einlasskanals bzw. Auslasskanals ein. Dies vereinfacht die Stapelbildung.In another embodiment, the domes of the respective additional disc may be sized and arranged to engage the domes of one of the adjacent main discs. Thus, the domes of the respective additional disc are divided into the formation of the respective inlet channel and outlet channel. This simplifies stacking.
Entsprechend einer vorteilhaften Weiterbildung können die Dome der jeweiligen Zusatzscheibe im Wesentlichen doppelt so hoch sein wie die Dome der Hauptscheiben. Hierdurch wird erreicht, dass im jeweiligen Zusatzverbindungskanal die parallel zur Stapelrichtung gemessene Höhe im Wesentlichen gleich groß ist wie im benachbarten Hauptverbindungskanal.According to an advantageous development, the dome of the respective additional disc can be substantially twice as high as the dome of the main discs. This ensures that in the respective additional connection channel the height measured parallel to the stacking direction is substantially the same as in the adjacent main connection channel.
Gemäß einer anderen Ausführungsform kann die jeweilige Zusatzscheibe so im Stapel angeordnet sein, dass sie im Bereich ihrer nicht von ihrem Domen eingefassten Öffnungen freistehend angeordnet ist, so dass der Zusatzverbindungskanal durch diese Öffnungen mit dem benachbarten Hauptverbindungskanal fluidisch verbunden ist. Auch bei dieser Bauweise wird innerhalb des Stapels ein interner Bypass realisiert, der die parallele Durchströmung des Zusatzverbindungskanals und des benachbarten Hauptverbindungskanals ermöglicht.According to another embodiment, the respective additional disc may be arranged in the stack so that it is arranged free-standing in the area of their not enclosed by their domes openings, so that the additional connection channel is fluidly connected through these openings with the adjacent main connection channel. Also in this construction, an internal bypass is realized within the stack, which allows the parallel flow through the additional connection channel and the adjacent main connection channel.
Gemäß einer anderen Weiterbildung können die Dome der jeweiligen Zusatzscheibe so dimensioniert und angeordnet sein, dass sie die benachbarte Hauptscheibe bezüglich der Längsmittelachse des jeweiligen Einlasskanals oder Auslasskanals radial außerhalb der Dome der benachbarten Hauptscheibe kontaktieren. Diese Bauweise ist toleranter gegenüber Maßabweichungen innerhalb des Herstellungsprozesses.According to another embodiment, the dome of the respective additional disc can be dimensioned and arranged so that they contact the adjacent main disc with respect to the longitudinal central axis of the respective inlet channel or outlet channel radially outside the dome of the adjacent main disc. This design is more tolerant of deviations in the manufacturing process.
Bei einer anderen Weiterbildung können die Dome der jeweiligen Zusatzscheibe in der Stapelrichtung etwa gleich hoch sein wie die Dome der Hauptscheiben. Hierdurch wird erreicht, dass bei außerhalb der Dome der Hauptscheibe kontaktierenden Domen der Zusatzscheibe die in der Stapelrichtung gemessene Höhe des Zusatzverbindungskanals etwa gleich groß ist wie des benachbarten Hauptverbindungskanals.In another development, the dome of the respective additional disc in the stacking direction may be about the same height as the dome of the main discs. This ensures that when outside of the dome of the main disc contacting domes of the additional disc measured in the stacking direction height of the additional connection channel is about the same size as the adjacent main connection channel.
Besonders vorteilhaft ist nun eine Ausführungsform, bei welcher alle Hauptscheiben identisch ausgestaltet sind. Dementsprechend bilden die Hauptscheiben Gleichteile, was aufgrund höherer Stückzahlen die Stückkosten reduziert. Zweckmäßig sind die identischen Hauptscheiben so ausgestaltet, dass sie sich so aufeinanderstapeln lassen, dass in der Stapelrichtung benachbarte Hauptscheiben parallel zur Stapelrichtung um 180° zueinander verdreht sind.Particularly advantageous is now an embodiment in which all the main discs are configured identically. Accordingly, the main discs form identical parts, which reduces the unit cost due to higher quantities. The identical main disks are expediently configured in such a way that they can be stacked on one another in such a way that adjacent main disks parallel to the stacking direction are rotated by 180 ° relative to one another in the stacking direction.
Wie erwähnt kann der hier vorgestellte Stapelscheibenwärmeübertrager grundsätzlich mit einer einzigen solchen Zusatzscheibe auskommen. Ebenso können jedoch gleichzeitig auch mehrere derartige Zusatzscheiben zum Einsatz kommen. Sofern zwei oder mehr Zusatzscheiben verwendet werden, sind diese gemäß einer vorteilhaften Ausführungsform identisch ausgestaltet, also ebenfalls als Gleichteile. Auch hier führt die Verwendung von Gleichteilen zu erhöhten Stückzahlen und reduzierten Stückpreisen.
Gemäß einer anderen vorteilhaften Ausführungsform können die Hauptscheiben und die jeweilige Zusatzscheibe jeweils einen Umlauf besitzen, wobei die Umläufe von in der Stapelrichtung benachbarten Scheiben, also zwei Hauptscheiben oder eine Hauptscheibe und eine Zusatzscheibe, ineinandergreifen und dadurch die Verbindungskanäle, also die Hauptverbindungskanäle und den jeweiligen Zusatzverbindungskanal dicht abschließen. Mit Hilfe dieser Umläufe kann auf ein zusätzliches Gehäuse, in welches der Stapel eingesetzt werden muss, verzichtet werden. Dementsprechend wird mit Hilfe der Umläufe ein gehäuseloser Stapelscheibenwärmeübertrager geschaffen. Zweckmäßig sind die Umläufe der Hauptscheiben und der Umlauf der jeweiligen Zusatzscheibe hinsichtlich Höhe und Neigung identisch, um das Ineinandergreifen zu vereinfachen.As mentioned above, the stacked disk heat exchanger presented here can in principle make do with a single such additional disk. Likewise, however, several such additional disks can be used at the same time. If two or more auxiliary disks are used, they are configured identically according to an advantageous embodiment, ie also as identical parts. Again, the use of identical parts leads to increased quantities and reduced unit prices.
According to another advantageous embodiment, the main disks and the respective additional disk can each have a circulation, wherein the circuits of adjacent disks in the stacking direction, ie two main disks or a main disk and an additional disk, interlock and thereby the connection channels, so the main connection channels and the respective additional connection channel close tightly. With the help of these revolutions can be dispensed with an additional housing in which the stack must be inserted. Accordingly, a caseless stacked plate heat exchanger is created with the help of the revolutions. Suitably, the revolutions of the main discs and the circulation of the respective additional disc are identical in terms of height and inclination in order to simplify the meshing.
