Aus der
Es ist die Aufgabe der vorliegenden Erfindung, eine Wärmetauscheranordnung, insbesondere für ein Fahrzeugheizgerät, vorzusehen, bei welcher Wärmeverluste gemindert sind.It is the object of the present invention to provide a heat exchanger arrangement, in particular for a vehicle heater, in which heat losses are reduced.
Erfindungsgemäß wird diese Aufgabe gelöst durch eine Wärmetauscheranordnung, insbesondere für ein Fahrzeugheizgerät, umfassend ein topfartiges inneres Wärmetauschergehäuse mit einer ersten Bodenwandung in einem ersten axialen Endbereich der Wärmetauscheranordnung und einer an die erste Bodenwandung anschließenden, eine Längsachse umgebenden ersten Umfangswandung, ein topfartiges äußeres Wärmetauschergehäuse mit einer zweiten Bodenwandung im ersten axialen Endbereich der Wärmetauscheranordnung und einer an die zweite Bodenwandung anschließenden, die Längsachse umgebenden zweiten Umfangswandung, wobei in einem zweiten axialen Endbereichder Wärmetauscheranordnung das innere Wärmetauschergehäuse und das äußere Wärmetauschergehäuse miteinander verbunden sind, sowie einen zwischen dem inneren Wärmetauschergehäuse und dem äußeren Wärmetauschergehäuse gebildeten Fluidströmungsraum. Dabei ist weiter vorgesehen, dass wenigstens im zweiten axialen Endbereich der Wärmetauscheranordnung im Aufbaumaterial des inneren Wärmetauschergehäuses oder/und im Aufbaumaterial des äußeren Wärmetauschergehäuses wenigstens eine nach außen offene Aussparung vorgesehen ist.According to the invention, this object is achieved by a heat exchanger arrangement, in particular for a vehicle heater, comprising a cup-shaped inner heat exchanger housing having a first bottom wall in a first axial end region of the heat exchanger assembly and a first peripheral wall surrounding a longitudinal axis, a cup-shaped outer heat exchanger housing having a first peripheral wall a second bottom wall in the first axial end region of the heat exchanger assembly and a second circumferential wall adjacent the second bottom wall, wherein the inner heat exchanger housing and the outer heat exchanger housing are interconnected in a second axial end region of the heat exchanger assembly, and one between the inner heat exchanger housing and the outer heat exchanger housing formed fluid flow space. It is further provided that at least one outwardly open recess is provided at least in the second axial end region of the heat exchanger assembly in the construction material of the inner heat exchanger housing and / or in the building material of the outer heat exchanger housing.
Dabei ist weiter vorgesehen, dass wenigstens im zweiten axialen Endbereich der Wärmetauscheranordnung wenigstens eine im Aufbaumaterial des inneren Wärmetauschergehäuses oder/und im Aufbaumaterial des äußeren Wärmetauschergehäuses nach außen offene Aussparung vorgesehen ist.It is further provided that at least one in the building material of the inner at least in the second axial end portion of the heat exchanger assembly Heat exchanger housing or / and is provided in the building material of the outer heat exchanger housing outwardly open recess.
Durch das Bereitstellen wenigstens einer Aussparung im Aufbaumaterial des inneren Wärmetauschergehäuses oder/und dem Aufbaumaterial des äußeren Wärmetauschergehäuses wird ein im Allgemeinen mit Luft gefüllter, grundsätzlich zum Fluidströmungsraum jedoch abgeschlossener Hohlraum geschaffen. Da die beiden Wärmetauschergehäuse, zumindest jedoch das durch die heißen Verbrennungsabgase stärker beaufschlagte innere Wärmetauschergehäuse im Allgemeinen aus Metallmaterial, beispielsweise aus Aluminium-Druckgussmaterial, aufgebaut sind, sorgt das Einbringen von Aussparungen in dieses Aufbaumaterial für eine Unterbrechung im Metallmaterial. Da das Aufbaumaterial der Wärmetauscheranordnung bzw. der Wärmetauschergehäuse desselben im Allgemeinen eine deutlich höhere Wärmeleitfähigkeit, mithin einen geringeren Wärmewiderstand aufweist, als beispielsweise die in einer derartigen Aussparung vorhandene Luft, wird der Wärmeaustrag aus der Wärmetauscheranordnung durch den somit allgemein bereitgestellten größeren Wärmewiderstand im Bereich der Aussparungen gemindert.By providing at least one recess in the building material of the inner heat exchanger housing and / or the building material of the outer heat exchanger housing a generally filled with air, but basically closed to the fluid flow space cavity is provided. Since the two heat exchanger housings, or at least the inner heat exchanger housings which are more strongly acted upon by the hot combustion gases, are generally constructed of metal material, for example of die-cast aluminum material, the introduction of recesses in this construction material ensures an interruption in the metal material. Since the building material of the heat exchanger assembly or the heat exchanger housing thereof generally has a significantly higher thermal conductivity, and thus a lower thermal resistance than, for example, the air present in such a recess, the Wärmeaustrag from the heat exchanger assembly by the thus generally provided greater thermal resistance in the region of the recesses reduced.
Um eine gegenseitige Beeinträchtigung mit dem Fluidströmungsraum zu vermeiden, wird vorgeschlagen, dass an einer von den Bodenwandungen abgewandten Stirnseite wenigstens eine Aussparung im Wesentlichen in axialer Richtung nach außen offen ist.In order to avoid mutual interference with the fluid flow space, it is proposed that at least one recess is open to the outside at an end face remote from the bottom walls, essentially in the axial direction.
Ein einfach zu realisierender, gleichwohl stabiler Aufbau kann dadurch erhalten werden, dass eine Mehrzahl von in Umfangsrichtung um die Längsachse aufeinander folgenden Aussparungen vorgesehen ist, oder/und dass wenigstens eine, vorzugsweise jede Aussparung um die Längsachse gekrümmt oder/und in Umfangsrichtung langgestreckt ist.An easy-to-realize, yet stable structure can be obtained by providing a plurality of circumferentially successive recesses in the circumferential direction, or / and that at least one, preferably each recess is curved about the longitudinal axis and / or elongated in the circumferential direction.
Um eine Durchströmung des Fluidströmungsraums mit einem zu erwärmenden Fluid zu ermöglichen bzw. auch das Abführen von beispielsweise in einem Brennerbereich eines Fahrzeugheizgeräts generierten Verbrennungsabgasen zu gewährleisten, wird weiter vorgeschlagen, dass im zweiten axialen Endbereich eine Fluideinlassöffnung zu dem Fluidströmungsraum oder/und eine Fluidauslassöffnung aus dem Fluidströmungsraum oder/und eine Abgasauslassöffnung aus einem von dem inneren Wärmetauschergehäuse umgebenen Abgasströmungsraum vorgesehen ist.In order to allow a flow through the fluid flow space with a fluid to be heated or to ensure the removal of, for example, generated in a burner region of a vehicle heater combustion exhaust gases is Furthermore, it is proposed that a fluid inlet opening to the fluid flow space or / and a fluid outlet opening from the fluid flow space and / or an exhaust gas outlet opening from an exhaust gas flow space surrounded by the inner heat exchanger housing be provided in the second axial end area.
Zur Bereitstellung von ausreichendem Bauraum für derartige Einlass- bzw. Auslassöffnungen wird vorgeschlagen, dass wenigstens eine im Umfangsbereich der Fluideinlassöffnung oder/und wenigstens eine im Umfangsbereich der Fluidauslassöffnung oder/und wenigstens eine im Umfangsbereich der Abgasauslassöffnung vorgesehene Aussparung wenigstens bereichsweise eine geringere Tiefe aufweist, als eine in einem mit der Fluideinlassöffnung oder/und der Fluidauslassöffnung oder/und der Abgasauslassöffnung sich im Wesentlichen nicht überschneidenden Umfangsbereich vorgesehene Aussparung. Dieser Aufbau hat zur Folge, dass dort, wo eine gegenseitige Beeinträchtigung mit einer Fluideinlassöffnung bzw. Fluidauslassöffnung oder einer Abgasauslassöffnung nicht besteht, Aussparungen oder eine Aussparung mit entsprechend größerer Tiefe vorgesehen werden kann, was zu einer weiteren Erhöhung des Wärmewiderstands führt.In order to provide sufficient installation space for such inlet or outlet openings, it is proposed that at least one recess provided in the peripheral region of the fluid inlet opening and / or at least one recess in the peripheral region of the fluid outlet opening and / or at least one recess provided in the peripheral region of the exhaust gas outlet opening has a smaller depth at least in regions than a recess provided in a peripheral area substantially unintersecting with the fluid inlet opening and / or the fluid outlet opening and / or the exhaust gas outlet opening and / or the exhaust gas outlet opening. The result of this construction is that, where there is no interference with a fluid inlet opening or exhaust outlet opening, recesses or a recess with a correspondingly greater depth can be provided, which leads to a further increase in the thermal resistance.
Eine kompakte Ausgestaltung der Wärmetauscheranordnung kann dadurch erreicht werden, dass im zweiten axialen Endbereich das innere Wärmetauschergehäuse eine den Fluidströmungsraum axial begrenzende Stirnwand aufweist oder/und eine die zweite Umfangswandung an ihrer Außenseite übergreifende und mit dieser verbundene dritte Umfangswandung aufweist.A compact embodiment of the heat exchanger arrangement can be achieved in that in the second axial end region, the inner heat exchanger housing has an end wall axially delimiting the fluid flow space and / or has a third circumferential wall which engages over the second peripheral wall on its outer side and is connected thereto.
Die Stirnwand kann in Umfangsrichtung ringartig umlaufend ausgebildet sein. Um jedoch den Durchfluss von Fluid zur Fluideinlassöffnung bzw. zur Flluidauslassöffnung gewährleisten zu können, wird vorgeschlagen, dass im Bereich der Fluideinlassöffnung oder/und im Bereich der Fluidauslassöffnung der Fluidströmungsraum in axialer Richtung sich über die Stirnwand hinaus erstreckt. Dies bedeutet, dass im Bereich dieser Öffnungen die ansonsten ringartig umlaufend ausgebildete Stirnwand unterbrochen sein kann bzw. diese Öffnungen umgebende Ausbauchungen aufweisen kann.The end wall may be formed circumferentially ring-like. However, in order to be able to ensure the flow of fluid to the fluid inlet opening or to the fluid outlet opening, it is proposed that in the region of the fluid inlet opening and / or in the area of the fluid outlet opening, the fluid flow space in the axial direction extend beyond the end wall. This means that in the region of these openings, the otherwise annularly circumferentially formed end wall may be interrupted or these openings may have surrounding bulges.
Um die Anlagerung von Verunreinigungen im Bereich der Wärmetauscheranordnung zu vermeiden, wird weiter vorgeschlagen, dass wenigstens eine Aussparung durch ein Abschlusselement abgeschlossen ist.In order to avoid the accumulation of impurities in the region of the heat exchanger arrangement, it is further proposed that at least one recess is closed off by a closure element.
Der durch das Vorsehen wenigstens einer Aussparung im Aufbaumaterial eines Wärmetauschergehäuses eingeführte thermische Isolationseffekt kann in besonders effizienter Weise genutzt werden, wenn in wenigstens einer Aussparung, vorzugsweise jeder Aussparung, Isoliermaterial mit geringerer Wärmeleitfähigkeit als das Aufbaumaterial des diese Aussparung aufweisenden Wärmetauschergehäuses enthalten ist.The introduced by the provision of at least one recess in the building material of a heat exchanger housing thermal insulation effect can be used in a particularly efficient manner, if in at least one recess, preferably each recess, insulating material with lower thermal conductivity than the building material of this recess having heat exchanger housing is included.
Dabei füllt das Isoliermaterial die wenigstens eine Aussparung (60) vorzugsweise im Wesentlichen vollständig aus.In this case, the insulating material preferably fills the at least one recess (60) substantially completely.
Bei einer besonders einfach zu realisierenden, eine sehr effiziente thermische Isolation bereitstellenden Ausgestaltung kann das Isoliermaterial Luft umfassen. Es sei hier darauf hingewiesen, dass bei einer weiteren Ausgestaltungsvariante eine Kombination verschiedener thermisch isolierender Isoliermaterialien vorgesehen sein kann. Beispielsweise kann in wenigstens einer Aussparung poröses oder zellenartig aufgebautes, schaumstoffartiges Material enthalten sein, in dessen Innenvolumenbereich Luft aufgenommen ist. Beispielsweise kann PU-Schaum oder geschäumtes Silikonmaterial eingesetzt werdenIn an embodiment that is particularly easy to implement and provides very efficient thermal insulation, the insulating material may comprise air. It should be noted here that in a further embodiment variant, a combination of different thermally insulating insulating materials may be provided. For example, in at least one recess porous or cell-like constructed, foam-like material may be included in the inner volume of air is received. For example, PU foam or foamed silicone material can be used
Das Aufbaumaterial wenigstens eines eine Aussparung aufweisenden Wärmetauschergehäuses umfasst vorzugsweise Metallmaterial, vorzugsweise Aluminium. Vorteilhafterweise bildet dabei Metallmaterial, also beispielsweise Aluminium, die Hauptbestandskomponente des Aufbaumaterials, insbesondere dann, wenn dieses Aufbaumaterial als Legierung bereitgestellt ist.The building material of at least one recess having a heat exchanger housing preferably comprises metal material, preferably aluminum. Advantageously, metal material, for example aluminum, forms the main constituent component of the building material, in particular if this building material is provided as an alloy.

In den Figuren ist eine beispielsweise in Verbindung mit einem brennstoffbetriebenen Fahrzeugheizgerät einsetzbare Wärmetauscheranordnung allgemein mit 10 bezeichnet. Die Wärmetauscheranordnung 10 umfasst zwei ineinander eingesetzte Wärmetauschergehäuse 12, 14. Das innere Wärmetauschergehäuse 12 umfasst in einem ersten axialen Endbereich 16 der Wärmetauscheranordnung 10 eine erste Bodenwandung 18 und an diese radial außen anschließend und in Richtung einer Längsachse L sich erstreckend bzw. die Längsachse L umgebend eine erste Umfangswandung 20. Auch das äußere Wärmetauschergehäuse 14 umfasst im ersten axialen Endbereich 16 der Wärmetauscheranordnung 10 eine zweite Bodenwandung 22 sowie radial außen an diese anschließend eine in Richtung der Längsachse L sich erstreckende bzw. diese umgebende zweite Umfangswandung 24. Es ist hier darauf hinzuweisen, dass im dargestellten Ausgestaltungsbeispiel die beiden Wärmetauschergehäuse 12, 14 mit ihren Bodenwandungen 18, 22 und ihren Umfangswandungen 20, 24 jeweils als integral ausgebildete Bauteile, diese beispielsweise hergestellt als Aluminium-Druckgrussteile, aufgebaut sind. Grundsätzlich könnten bei einem oder beiden der Wärmetauschergehäuse 12, 14 die Umfangswandungen bzw. Bodenwandungen auch als separat aufgebaute und miteinander verbundene Bauteile bereitgestellt sein.In the figures, a heat exchanger assembly employable, for example, in connection with a fuel-fired vehicle heater is generally indicated at 10. The
In einem von den Bodenwandungen 18, 22 entfernten zweiten axialen Endbereich 26 der Wärmetauscheranordnung 10 bildet das innere Wärmetauschergehäuse 12 mit einem ringartigen Endabschnitt 28 einen Anschluss an das äußere Wärmetauschergehäuse 14. In diesem ringartigen Endabschnitt 28 erstreckt das innere Wärmetauschergehäuse 12 sich über dessen zweiten Umfangswandung 20 hinaus nach radial außen und weist eine in Richtung auf den ersten axialen Endbereich zu sich erstreckende dritte Umfangswandung 30 auf. Diese dritte Umfangswandung 30 übergreift die zweite Umfangswandung 24 radial außen und ist mit dieser unter Zwischenlagerung eines O-ringartigen Dichtelements 32 beispielsweise durch Verpressung, Verschweißung, Verklebung oder dergleichen fest verbunden. Auf diese Art und Weise ist zwischen dem inneren Wärmetauschergehäuse 12 und dem äußeren Wärmetauschergehäuse 14 ein allgemein mit 34 bezeichneter Fluidströmungsraum gebildet, der in axialer Richtung am zweiten axialen Endbereich 26 durch eine zwischen der ersten Umfangswandung 20 und der dritten Umfangswandung 30 des inneren Wärmetauschergehäuses 12 sich erstreckende Stirnwand 36 abgeschlossen bzw. begrenzt ist. Diese Stirnwand 36 ist um die Längsachse L ringartig umlaufend ausgebildet, liegt dabei vorteilhafterweise im Wesentlichen in einem axialen Bereich bezüglich der Längsachse L, also im Wesentlichen orthogonal dazu, und ist, wie die
In dem axial über das äußere Wärmetauschergehäuse 14 sich hinaus erstreckenden Verbindungsbereich 28 weist das innere Wärmetauschergehäuse 12 eine in einem Fluideinlassstutzen 38 ausgebildete Fluideinlassöffnung 40 sowie eine in einem Fluidauslassstutzen 42 bereitgestellte Fluidauslassöffnung 44 auf. Die Fluideinlassöffnung 40 und die Fluidauslassöffnung 44 sind zum Fluidströmungsraum 34 offen. Wie die
Im zweiten axialen Endbereich 26 der Wärmetauscheranordnung 10 ist ferner in einem Abgasauslassstutzen 46 eine Abgasauslassöffnung 48 vorgesehen. Diese ist zur Innenseite der ersten Umfangswandung 20 und somit zu einem vom inneren Wärmetauschergehäuse 12 umgebenen Abgasströmungsraum 50 offen. Wie die
Im zweiten axialen Endbereich 26 der Wärmetauscheranordnung 10 ist im dargestellten Ausgestaltungsbeispiel im inneren Wärmetauschergehäuse 12, insbesondere in dem an den Fluidströmungsraum 34 axial anschließenden Endabschnitt 28 desselben, eine Mehrzahl von beispielsweise bei einem Gieß-Herstellungsvorgang des inneren Wärmetauschergehäuses 12 oder/und durch spanabhebende Bearbeitung bereitgestellte Aussparungen 60 im Aufbaumaterial des inneren Wärmetauschergehäuses 12 vorgesehen. Die Aussparungen 60 sind in Umfangsrichtung um die Längsachse L aufeinander folgend angeordnet und weisen beispielsweise zueinander gleiche Umfangserstreckungen oder/und Radialerstreckungen auf. Die Aussparungen 60 sind vorzugsweise, angepasst an die ringartige Gestalt des Wärmetauschergehäuses, gekrümmt oder/und in Umfangsrichtung langgestreckt ausgebildet. Zwischen den einzelnen Aussparungen 60 liegen diese trennende Wandungen 62. Die axiale Tiefe der Aussparungen 60 ist derart bemessen, dass wie die
Wie die
Um den durch das Bereitstellen der Aussparungen 60 eingeführten Isolationseffekt effizient nutzen zu können, sind einige, vorzugsweise alle Aussparungen 60 mit thermisch isolierendem Material gefüllt. Thermisch isolierende bedeutet hier, dass das Material, mit welchem die Aussparung/en 60 gefüllt ist/sind, eine geringere Wärmeleitfähigkeit aufweist, als das Aufbaumaterial des diese Aussparungen 60 aufweisenden Wärmetauschergehäuses. Beispielsweise können diese Aussparungen 60 im Wesentlichen vollständig mit Luft gefüllt sein, welche eine um Größenordnungen kleinere Wärmeleitfähigkeit aufweist, als das zum Aufbau eines derartigen Wärmetauschergehäuses beispielsweise eingesetzte Aluminiummaterial. Es sei in diesem Zusammenhang darauf hingewiesen, dass für die Zwecke der vorliegenden Erfindung die Wärmeleitfähigkeit in dem für den Betrieb einer derart aufgebauten Wärmetauscheranordnung relevanten Temperaturbereich beispielsweise im Bereich von -50 °C bis +250 °C in demjenigen Bereich, in welchem die Aussparungen 60 im Wärmetauschergehäuse bereitgestellt sind, betrachtet werden kann.In order to efficiently use the insulating effect introduced by providing the
Wenigstens ein Teil des thermisch isolierenden Materials in wenigstens einer Aussparung kann als Festkörpermaterial bereitgestellt sein. Dieses kann beispielsweise porös oder zellenartig, beispielsweise als Schaumstoffmaterial, z.B. PU-Schaum oder Silikonschaum, bereitgestellt sein, das in seinem Innenvolumenbereich Luft enthält. Auch ist es möglich, dass das die Aussparungen 60 oder wenigstens einen Teil der Aussparungen 60 überdeckende Dichtelement 75 mit in wenigstens eine der Aussparungen 60, vorzugsweise jede davon überdeckte Aussparung 60, eingreifenden Materialabschnitten zum Bereitstellen des Isoliermaterials ausgebildet ist.At least a portion of the thermal insulating material in at least one recess may be provided as solid state material. This may, for example, be porous or cellular, for example as a foam material, e.g. PU foam or silicone foam, be provided, which contains air in its interior volume area. It is also possible that the sealing
Es ist selbstverständlich, dass bei dem erfindungsgemäßen Aufbau alternativ oder zusätzlich zu den in den Figuren dargestellten Aussparungen im Aufbaumaterial eines Wärmetauschergehäuses auch an anderen Bereichen oder in anderer Richtung, beispielsweise nach radial außen offene, vorteilhafterweise auch durch ein Abschlusselement abgeschlossene Aussparungen vorgesehen sein können.It is understood that in the structure according to the invention, alternatively or in addition to the recesses shown in the figures in the building material of a heat exchanger housing can also be provided at other areas or in other directions, for example radially outwardly open, advantageously also completed by a closing element recesses.
