- additional webs 44, 45 on the inside can - as in particular Fig. 4c shows - the stiffness can be increased or increased further.
- the beads 32, 33 can in the designs according to the Fig. 3a to 3d or 4a to 4d, for example, alternatively be shaped as in Fig. 5f is shown. Thus, they can each be substantially V-shaped, in particular in cross-section, the tip of the "V” and the ends opposite the tip of the "V” being rounded or curved.
- extruded flat tubes in radiators can also lead to lower investment costs for the machinery. It is namely possible to realize different internal geometries with a constant outer geometry of the flat tubes in order to be able to react easily to different requirements. This can for example be such that different types of vehicles, such as cars and commercial vehicles or for various motor vehicle engines in the radiators in question flat tubes are used, each having the same outer geometry.
- the internal geometry can in each case be adapted to the specific application, which can be realized well in the extrusion process.

Description
Die Erfindung betrifft einen Heizkörper für einen Kühlkreislauf einer luft- oder wasserseitig geregelten Klimaanlage eines Kraftfahrzeuges, Klimagerät für eine Kraftfahrzeug-Klimaanlage, einen Kühlkreislauf für eine luft- oder wasserseitig geregelten Kraftfahrzeug-Klimaanlage sowie eine Klimaanlage für ein Kraftfahrzeug.The invention relates to a radiator for a cooling circuit of an air or water side controlled air conditioning of a motor vehicle, air conditioner for a motor vehicle air conditioning, a cooling circuit for an air or water side regulated automotive air conditioning and air conditioning for a motor vehicle.
Ein Klimatisierungssystem für Kraftfahrzeuge besteht in aller Regel aus den Subsystemen Heizkreislauf und Kältekreislauf, sowie dem Klimagerät, einer Luftführung zum Klimagerät und den Austrittsöffnungen sowie aus dem Bediengerät für die Klimaanlage (inklusive der dazu gehörenden Regelung und den zugehörigen Sensoren).An air conditioning system for motor vehicles usually consists of the subsystems heating circuit and refrigeration circuit, as well as the air conditioner, an air duct to the air conditioner and the outlet openings and from the control unit for the air conditioning (including the associated control and the associated sensors).
Das Klimagerät weist dabei einen Heizkörper auf. Der Heizkörper ist in einem Kühlkreislauf integriert. Das Kühlmittel dieses Kühlkreislaufs wird beispielsweise auch zum Motor des Kraftfahrzeuges geführt.The air conditioner has a radiator. The radiator is integrated in a cooling circuit. The coolant of this cooling circuit is for example also led to the engine of the motor vehicle.
Gelötete Heizkörper werden im PKW- und NKW-Bereich für unterschiedliche Motoren und unterschiedlichen Kühlkreisläufen in luft- und wasserseitig geregelten Klimaanlagen eingesetzt. Die dabei in den unterschiedlichen Kühlkreisläufen, d.h. insbesondere in unterschiedlichen Fahrzeugen, auftretenden Beanspruchungen, insbesondere Beanspruchungen der Heizkörper, unterscheiden sich zum Teil deutlich im Hinblick auf Temperaturen, Drücke, Kühlmittel, Volumenstrom, etc.. Dies hat zur Folge, dass die Flachrohre verschiedener Heizkörper im Hinblick auf die Wandstärke unterschiedlich dimensioniert sein können oder müssen. So muss beispielsweise bei Nutzkraftfahrzeuganwendungen die Wandstärke der Flachrohre häufig größer sein als bei Anwendungen in Personenkraftwagen. Aber auch im Bereich der Personenkraftwagen wie auch im Bereich der Nutzkraftwagen bestehen - für sich genommen - bei verschiedenen Fahrzeugtypen unterschiedliche Anforderungen an die Dimensionierung der Wandstärke der Flachrohre.Soldered radiators are used in the passenger car and commercial vehicle sector for different engines and different cooling circuits in air- and water-side controlled air conditioning systems. The occurring in the different cooling circuits, ie in particular in different vehicles, stresses, in particular stresses of the radiator, differ in part significantly in terms of temperatures, pressures, coolant, flow, etc. This has the consequence that the flat tubes of different radiators can be dimensioned differently in terms of wall thickness or need. For example, in commercial vehicle applications, the wall thickness of the flat tubes often has to be greater than in passenger car applications. But also in the field of passenger cars as well as in the field of commercial vehicles exist - taken by itself - in different vehicle types different requirements for the dimensioning of the wall thickness of the flat tubes.
Bekannte Heizkörper weisen in aller Regel zumindest einen Kühlmittelkasten auf, der einen Boden ausbildet. Innerhalb des Kühlmittelkastens können eine oder mehrere Trennwände vorgesehen sein, die das Innere dieses Kastens in Teilkammern unterteilen und zur Umlenkung des den Heizkörper durchströmenden Kühlmittels dienen. Die Trennwände können so angeordnet sein, dass sie eine Umlenkung in der Tiefe bewirken oder so, dass sie eine Umlenkung in der Breite bewirken. Im Rahmen der Herstellung werden die eine Trennwand bzw. die Trennwände in die Kästen eingesetzt. Ferner werden die Flachrohre in den Boden des Kastens eingesteckt oder an diesen angeformt. Die Herstellung der Flachrohre selbst erfolgt bei den bekannten Heizkörpern so, dass ein entsprechend zugeschnittenes Blech konstanter Dicke mittels einer speziellen Vorrichtung, die Rollensätze aufweist, zu einem Flachrohr geformt wird. Das Flachrohr wird dann an der Stoßkante verschweißt oder verlötet. Es kann auch vorgesehen sein, dass verlötete Scheiben eingesetzt werden.Known radiators usually have at least one coolant box, which forms a bottom. Within the coolant box, one or more partitions may be provided, which divide the interior of this box into sub-chambers and serve to deflect the coolant flowing through the radiator. The partitions may be arranged to effect a deflection in depth or to effect a deflection in the width. As part of the production, the one partition or the partitions are inserted into the boxes. Furthermore, the flat tubes are inserted into the bottom of the box or formed on this. The manufacture of the flat tubes themselves is carried out in the known radiators so that a correspondingly cut sheet of constant thickness by means of a special device having roller sets, is formed into a flat tube. The flat tube is then welded or soldered to the abutting edge. It can also be provided that soldered discs are used.
Um den Anforderungen an die bereits angesprochenen, verschiedenen Beanspruchungen gerecht zu werden, wird üblicherweise bei jeder konkreten Anwendung zunächst die maximal im Betrieb auftretenden Spannung der Flachrohre ermittelt. In Abhängigkeit dieser maximal auftretenden Spannung wird anschließend die erforderliche Blechdicke des Blechs bestimmt, aus dem dann das Flachrohr in erläuterter Weise geformt wird.In order to meet the requirements of the already mentioned, different demands, usually the maximum occurring during operation voltage of the flat tubes is usually determined in each specific application. Depending on this maximum occurring voltage then the required sheet thickness of the sheet is determined, from which then the flat tube is formed in an illustrated manner.

Erfindungsgemäß wird ein Heizkörper für einen Kühlkreislauf einer luft- oder wasserseitig geregelten Klimaanlage eines Kraftfahrzeuges vorgeschlagen. Der Heizkörper weist eine Vielzahl von von einem Kühlmittel durchströmbaren Flachrohren auf. Diese Flachrohre weisen jeweils zur Begrenzung zumindest eines sich im Flachrohrinneren erstreckenden Kanals eine Flachrohrwand auf. Die (jeweilige) Flachrohrwand eines, mehrerer oder aller dieser Flachrohre weist unterschiedliche Wandstärken auf, wobei das wenigstens eine unterschiedliche Wandstärken aufweisende Flachrohr zumindest eine Sicke ausbildet, wobei die Wandstärke der Flachrohrwand im quer bzw. senkrecht zur Längsachse des Flachrohres betrachteten Querschnitt in den in Breitenrichtung gelegenen Endbereichen und in den sich, insbesondere beidseits, an die wenigstens eine Sicke anschließenden Bereichen größer ist als in den Bereichen, die sich in Breitenrichtung gesehen an die in Breitenrichtung gelegenen Endbereiche anschließen, und / oder größer ist als in den Bereichen, die sich in Breitenrichtung gesehen an die sich an die wenigstens eine Sicke anschließenden Bereiche anschließen und wobei die Flachrohre extrudierte Flachrohre sind. Erfindungsgemäß sind die Flachrohre des Heizkörpers extrudierte Flachrohre, wobei die jeweiligen Flachrohrwände dieses bzw. dieser Flachrohre unterschiedliche Wandstärken aufweisen. Dabei kann vorgesehen sein, dass die unterschiedlichen Wandstärken im Rahmen des Extrudierens ausgebildet worden sind.According to the invention, a radiator for a cooling circuit of an air or water side controlled air conditioning of a motor vehicle is proposed. The radiator has a multiplicity of flat tubes through which a coolant can flow. These flat tubes each have a flat tube wall for delimiting at least one channel extending in the flat tube interior. The (respective) flat tube wall of one, several or all of these flat tubes has different wall thicknesses, wherein the at least one different wall thicknesses having flat tube forms at least one bead, wherein the wall thickness of the flat tube wall in transverse or perpendicular to the longitudinal axis of the flat tube considered cross-section in the width direction lying end regions and in which, in particular on both sides, is adjacent to the at least one bead adjacent areas greater than in the areas that are seen in the width direction to the widthwise end portions, and / or greater than in the areas that are in Width direction seen at the connect to the at least one bead subsequent areas and wherein the flat tubes are extruded flat tubes. According to the invention, the flat tubes of the radiator are extruded flat tubes, wherein the respective flat tube walls of this or these flat tubes have different wall thicknesses. It can be provided that the different wall thicknesses have been formed in the context of extrusion.
Wie angesprochen, weist der Heizkörper eine Vielzahl von Flachrohren auf. Es kann vorgesehen sein, dass sämtliche Flachrohre des Heizkörpers identisch gestaltet sind. Es kann aber auch vorgesehen sein, dass der Heizkörper unterschiedlich gestaltete Flachrohre aufweist. Zur Vereinfachung der folgenden Darstellungen sei vorab angemerkt, dass Ausführungen, die sich insbesondere auf die Ausgestaltung eines oder der Flachrohre des erfindungsgemäßen Heizkörpers beziehen, im Folgenden insbesondere in Bezug auf "ein" Flachrohr dargestellt werden. Der erfindungsgemäße Heizkörper bzw. dessen Weiterbildungen kann selbstverständlich auch jeweils mehrere Flachrohre der jeweils geschilderten Art aufweisen oder es kann vorgesehen sein, dass alle Flachrohre in der jeweils geschilderten Art ausgebildet sind.As mentioned, the radiator has a variety of flat tubes. It can be provided that all flat tubes of the radiator are designed identically. But it can also be provided that the radiator has differently shaped flat tubes. To simplify the following illustrations, it should be noted in advance that embodiments which relate in particular to the configuration of one or the flat tubes of the radiator according to the invention are shown below in particular with reference to "one" flat tube. The radiator according to the invention or its developments may of course also each have a plurality of flat tubes of the type described in each case or it may be provided that all flat tubes are formed in the manner described in each case.
In vorteilhafter Ausgestaltung weist die Flachrohrwand des Flachrohres in ihrem quer bzw. senkrecht zur Flachrohrlängsachse gelegenen Querschnitt unterschiedliche Wandstärken auf. Es kann vorgesehen sein, dass im Wesentlichen sämtliche in der angesprochenen Längsrichtung gesehenen Querschnitte des Flachrohres identisch gestaltet sind. Alternativ kann allerdings auch vorgesehen sein, dass in der angesprochenen Längsrichtung unterschiedliche Querschnitte existieren. Beispielsweise kann auch vorgesehen sein, dass die in der angesprochenen Längsrichtung des Flachrohres in verschiedenen Querschnitten unterschiedliche Wandstärken gegeben sind. Besonders bevorzugt ist allerdings vorgesehen, dass die Flachrohrwand zwar in einem senkrecht zur Flachrohrlängsachse betrachteten Querschnitt unterschiedliche Wandstärken aufweist, wobei diese Wandstärken für jede Stelle des Querschnitts in Flachrohrlängsrichtung allerdings konstant sind.In an advantageous embodiment, the flat tube wall of the flat tube has different wall thicknesses in its transverse cross-section or perpendicular to the flat tube longitudinal axis. It can be provided that essentially all cross-sections of the flat tube seen in the mentioned longitudinal direction are designed identically. Alternatively, however, it may also be provided that different cross sections exist in the longitudinal direction mentioned. For example, it can also be provided that in the mentioned longitudinal direction of the flat tube in different cross-sections different wall thicknesses are given. However, it is particularly preferably provided that the flat tube wall has different wall thicknesses in a cross-section considered perpendicular to the flat tube longitudinal axis, although these wall thicknesses are constant for each point of the cross-section in the flat tube longitudinal direction.
In einer besonders zu bevorzugenden Ausgestaltung ist das Verhältnis der maximalen Wandstärke zur minimalen Wandstärke des Flachrohrs größer als 1,1 oder größer als 1,2 oder größer als 1,3 oder größer als 1,4 oder größer als 1,5 oder größer als 1,7 oder größer als 1,9 oder größer als 2. Es kann auch vorgesehen sein, dass das angesprochene Verhältnis größer als 2,5 oder größer als 3 ist. Auch deutlich größere Werte sind bevorzugt. In einer besonders vorteilhaften Gestaltung beziehen sich die angesprochenen Verhältnisse auf einen senkrecht zur Rohrlängsachse gelegenen Querschnitt bzw. auf die senkrecht zur Rohrlängsachse gelegenen Querschnitte.In a particularly preferable embodiment, the ratio of the maximum wall thickness to the minimum wall thickness of the flat tube is greater as 1.1 or greater than 1.2 or greater than 1.3 or greater than 1.4 or greater than 1.5 or greater than 1.7 or greater than 1.9 or greater than 2. It may also be provided in that the mentioned ratio is greater than 2.5 or greater than 3. Also significantly larger values are preferred. In a particularly advantageous embodiment, the aforementioned relationships relate to a cross section lying perpendicular to the tube longitudinal axis or to the cross sections located perpendicular to the tube longitudinal axis.
Gemäß einer vorteilhaften Weiterbildung sind die Wandstärken des Flachrohres zumindest qualitativ an die im Betrieb und bei Einsatz in einem Kühlkreislauf einer luft- oder wasserseitig geregelten Klimaanlage eines Kraftfahrzeugs auftretende Spannungsverhältnisse in der Flachrohrwand angepasst. Dies kann insbesondere so sein, dass an den hoch beanspruchten Stellen, also an den Stellen in denen in der Flachrohrwand eine hohe Spannung auftritt, auch größere Wandstärken gegeben sind und an Stellen, an denen die Spannungsverhältnisse in der Flachrohrwand geringer sind, geringere Wandstärken gegeben sind. Dabei kann vorgesehen sein, dass diese qualitative Anpassung recht grob ist. Es kann auch vorgesehen sein, dass die unterschiedliche Wandstärke quantitativ oder quantitativ angenähert an die im Betrieb und beim Einsatz in einem Kühlkreislauf einer luft- oder wasserseitig geregelten Klimaanlage eines Kraftfahrzeuges auftretende Spannungsverhältnisse in der Flachrohrwand angepasst ist. Dies kann beispielsweise so sein, dass die Wandstärke zumindest zu einem überwiegenden Teil ein proportionales Abbild der Spannungsverhältnisse in der Flachrohrwand ist.According to an advantageous development, the wall thicknesses of the flat tube are at least qualitatively adapted to the voltage conditions in the flat tube wall occurring during operation and when used in a cooling circuit of an air or water-side controlled air conditioning system of a motor vehicle. This may in particular be such that at the highly stressed points, ie at the points where in the flat tube wall, a high voltage occurs, even greater wall thicknesses are given and are given at locations where the stress ratios in the flat tube wall are smaller, lower wall thicknesses , It can be provided that this qualitative adaptation is quite crude. It can also be provided that the different wall thickness is adapted quantitatively or quantitatively approximated to the voltage conditions occurring in the flat tube wall during operation and when used in a cooling circuit of an air or water side controlled air conditioning system of a motor vehicle. This can for example be such that the wall thickness is at least for the most part a proportional representation of the stress conditions in the flat tube wall.
Besonders vorteilhaft ist allerdings bereits eine qualitative Anpassung an die Spannungsverhältnisse, und zwar insbesondere bezogen auf den senkrecht zur Flachrohrlängsachse gelegenen Querschnitt.However, a qualitative adaptation to the stress conditions is already particularly advantageous, in particular with respect to the cross-section perpendicular to the flat tube longitudinal axis.
Es ist insbesondere vorgesehen, dass der Heizkörper zumindest einen Kühlmittelkasten aufweist, in welchem die Flachrohre mit zumindest einem ihrer Enden münden. Besonders bevorzugt weist der Heizkörper zwei Kühlmittelkästen auf. Bei einer Gestaltung mit zwei Kühlmittelkästen kann beispielsweise vorgesehen sein, dass diese beabstandet zueinander vorgesehen sind, wobei zwischen diesen Kästen die Flachrohre des Heizkörpers angeordnet sind und mit ihrem einen Ende in den einen dieser Kühlmittelkästen münden und mit ihrem anderen Ende in den anderen ihrer Kühlmittelkästen enden. Insbesondere bei einer solchen Gestaltung kann vorgesehen sein, dass die Flachrohre durchgehend im Wesentlichen gerade ausgebildet sind. Die Flachrohrenden können beispielsweise jeweils verdrillt sein, und zwar insbesondere um 90°. Bevorzugt ist allerdings auch, dass die Flachrohre frei von verdrillten Enden sind.It is provided in particular that the radiator has at least one coolant box in which the flat tubes open with at least one of their ends. Particularly preferably, the radiator on two coolant boxes. For example, in a design with two coolant boxes be provided that they are spaced from each other, between these boxes, the flat tubes of the radiator are arranged and open at one end in the one of these coolant boxes and end with its other end in the other of their coolant boxes. In particular, in such a design can be provided that the flat tubes are continuously formed substantially straight. The flat tube ends, for example, each be twisted, in particular by 90 °. However, it is also preferred that the flat tubes are free of twisted ends.
In vorteilhafter Ausgestaltung weist wenigstens ein Kühlmittelkasten zumindest eine Trennwand auf, mittels welcher der Innenraum dieses Kühlmittelkasten in voneinander getrennte Teilkammern unterteilt ist. Es kann vorgesehen sein, dass eine solche Trennwand eine Quertrennwand ist, die quer zur Längsachse des Kühlmittelkastens angeordnet ist. Eine solche Trennwand kann auch eine Längstrennwand sein, die im Wesentlichen in Längsrichtung des Kühlmittelkastens verläuft. Auch Kombinationen solcher Trennwände sind bevorzugt. Die angesprochenen Trennwände können insbesondere für eine Umlenkung des Kühlmittels in der Breite bzw. in der Tiefe vorgesehen sein. Ferner kann vorgesehen sein, dass in Längsrichtung eine Vielzahl von Quertrennwänden beabstandet zueinander angeordnet sind.In an advantageous embodiment, at least one coolant box has at least one partition, by means of which the interior of this coolant box is divided into separate sub-chambers. It can be provided that such a partition wall is a transverse partition, which is arranged transversely to the longitudinal axis of the coolant box. Such a partition may also be a longitudinal partition which extends substantially in the longitudinal direction of the coolant box. Combinations of such partitions are also preferred. The mentioned partitions may be provided in particular for a deflection of the coolant in the width or in the depth. Furthermore, it can be provided that a plurality of transverse partition walls are arranged at a distance from one another in the longitudinal direction.
In vorteilhafter Weiterbildung weist das Flachrohr im quer bzw. senkrecht zu seiner Längsachse betrachteten Querschnitt zumindest eine Sicke auf.In an advantageous development, the flat tube has at least one bead in the cross-section viewed transversely or perpendicular to its longitudinal axis.
In besonders zu bevorzugender Ausgestaltung weist das Flachrohr in einem bzw. in seinen quer bzw. senkrecht zu seiner Längsachse betrachteten Querschnitten in zwei gegenüberliegenden Wandabschnitten der Flachrohrwand jeweils eine Sicke auf, wobei diese gegenüberliegenden Wandabschnitte für die Bildung von voneinander getrennten Strömungskanälen aneinander stoßen. Dies kann beispielsweise so sein, dass die Flachrohrwand an einer bestimmten Stelle unter Bildung einer Sicke nach innen gezogen ist und an dem gegenüberliegenden Wandabschnitt dieser Sicke ebenfalls die Flachrohrwand unter Bildung einer Sicke nach innen gezogen ist, wobei diese gegenüberliegenden Wandabschnitte einander kontaktieren, und zwar insbesondere im Sickenbereich. Es kann vorgesehen sein, dass sich diese Sicken entlang der gesamten Länge des Flachrohrs erstrecken, so dass mittels der aneinanderstoßenden Sicken verschiedene Strömungskanäle für das Kühlmittel gebildet werden.In a particularly preferable embodiment, the flat tube in each case in its transverse or perpendicular to its longitudinal axis considered cross sections in two opposite wall portions of the flat tube wall in each case a bead, said opposite wall sections abut each other for the formation of separate flow channels. This can be, for example, such that the flat tube wall is pulled inwards at a certain point to form a bead and the flat tube wall is pulled inwards on the opposite wall section of this bead, forming a bead, these opposite wall sections contact each other, in particular in the bead area. It can be provided that these beads extend along the entire length of the flat tube, so that by means of the abutting beads different flow channels for the coolant are formed.
Im senkrecht zur Längsachse des Flachrohres betrachteten Querschnitte ist die Sicke bzw. sind die Sicken vorteilhafter Weise an der breiten Seite des Flachrohres angeordnet. Im angesprochenen Querschnitt erstreckt sich das Flachrohr in einer Breitenrichtung und einer senkrecht hierzu gelegen Höhenrichtung. Die Breitenrichtung ist dabei die Richtung, in der das Flachrohr größere Abmaße aufweist als in Höhenrichtung. In Höhenrichtung ist die Ausdehnung des Flachrohres also geringer als in Breitenrichtung, so dass es flach ist.In cross section considered perpendicular to the longitudinal axis of the flat tube, the bead or the beads are advantageously arranged on the broad side of the flat tube. In the addressed cross-section, the flat tube extends in a width direction and a height direction perpendicular thereto. The width direction is the direction in which the flat tube has larger dimensions than in the vertical direction. In the height direction, the expansion of the flat tube is thus less than in the width direction, so that it is flat.
Es kann auch vorgesehen sein, dass an mehreren in Breitenrichtung beabstandeten Stellen im quer zur Flachrohrlängsachse betrachteten Querschnitt jeweils wenigstens eine Sicke vorgesehen ist. Dabei kann vorgesehen sein, dass an mehreren in Breitenrichtung voneinander beabstandeten Stellen jeweils auf gegenüberliegenden Seiten Sicken vorgesehen sind, wobei die gegenüberliegenden Bereiche, die jeweils die Sicken ausbilden, einander kontaktieren so dass jeweils voneinander getrennte Strömungskanäle ausgebildet werden. Mittels derartiger Sicken bzw. Sickenpaare kann das Flachrohr beispielsweise für eine einfache oder mehrfache Umlenkung ausgebildet sein. Dies kann beispielsweise so sein, dass in einem Kanal des Flachrohres, der mittels eines solchen Sickenpaares gebildet bzw. von einem benachbarten Kanal abgetrennt ist, das Kühlmittel von einem Kühlmittelkasten in einen anderen, gegenüberliegenden Kühlmittelkasten strömt, dort umgelenkt wird und durch einen weiteren Kanal des gleichen Flachrohres zurückströmt. Eine solche Umlenkung kann mehrfach vorgesehen sein, wobei jeweils hier benachbarte Kanäle des Flachrohres mittels einer angesprochenen Sicke oder eines angesprochenen Sickenpaares voneinander abgetrennt sein können.It may also be provided that in each case at least one bead is provided at a plurality of points spaced in the width direction in the cross section considered transversely to the flat tube longitudinal axis. It can be provided that are provided at several spaced apart in the width direction points each on opposite sides beads, the opposite regions, each forming the beads contact each other so that each separate flow channels are formed. By means of such beads or bead pairs, the flat tube may be formed, for example, for a single or multiple deflection. This can for example be such that in a channel of the flat tube, which is formed by means of such a pair of beads or separated from an adjacent channel, the coolant flows from one coolant box into another, opposite coolant box, is deflected there and through a further channel of the same flat tube flows back. Such a deflection can be provided multiple times, in each case adjacent channels of the flat tube can be separated from each other by means of an addressed bead or an addressed pair of beads.
Das Flachrohr, die Ausbildung des oder der Kühlmittelkästen sowie die Strömungsverschaltung kann - insbesondere mittels einer oder mehrerer in dem oder den Kühlmittelkästen angeordneten Trennwände - so sein, dass das gleiche Flachrohr im Betrieb in unterschiedlichen, entgegengesetzten Strömungsrichtungen durchströmt wird, wozu separate Kanäle ausgebildet werden.The flat tube, the formation of the coolant boxes or the flow interconnection can - in particular by means of one or more arranged in the coolant or the partitions - be such that the same flat tube is flowed through during operation in different, opposite flow directions, to which separate channels are formed.
In einer vorteilhaften Ausgestaltung ist vorgesehen, dass das Flachrohr einen oder mehrere Stützstege aufweist, die bzw. der im Inneren des Flachrohres sich an gegenüberliegenden Wandabschnitten der Flachrohrwand abstützt. Dies kann beispielsweise so sein, dass der oder die Stützstege gegenüberliegende Abschnitte der in Breitenrichtung des Flachrohres verlaufenden Flachrohrwand gegenüber einander abstützt bzw. sich selbst an diesen gegenüberliegenden Abschnitten abstützt. Der bzw. die Stützstege können so ausgebildet sein, dass sie sich entlang der gesamten Länge des Flachrohres erstrecken. Solche Stützstege können beispielsweise zur Erhöhung der Steifigkeit vorgesehen sein. Mittels der Stützstege kann ein Kanal bzw. Teilkanal des Flachrohres in Teilkanäle unterteilt sein. Es kann dabei vorgesehen sein, dass diese Teilkanäle, die mittels eines Stützsteges ausgebildet werden, in gleicher Strömungsrichtung vom Kühlmittel durchströmt werden bzw. in die jeweils gleichen Kammern des oder der Kühlmittelkästen münden.In an advantageous embodiment, it is provided that the flat tube has one or more support webs, which is or in the interior of the flat tube is supported on opposite wall portions of the flat tube wall. This can for example be such that the one or more support webs opposite portions of the extending in the width direction of the flat tube flat tube wall relative to each other is supported or supported itself on these opposite sections. The or the support webs may be formed so that they extend along the entire length of the flat tube. Such support webs may be provided, for example, to increase the rigidity. By means of the support webs, a channel or sub-channel of the flat tube can be divided into sub-channels. It can be provided that these sub-channels, which are formed by means of a support web, are flowed through in the same flow direction by the coolant or open into the respective same chambers of the or the coolant boxes.
In besonders zu bevorzugender Ausgestaltung weist zumindest ein Kühlmittelkasten zumindest eine Trennwand auf, mittels welcher der Innenraum dieses Kühlmittelkastens in voneinander getrennte Teilkammern unterteilt wird, wobei in die Trennwand Schlitze eingebracht sind, in welchen jeweils ein Flachrohr aufgenommen wird. Dies ist insbesondere so, dass das Flachrohr an einem in seiner Längsrichtung gesehenen Ende in einen Schlitz der Trennwand eingesteckt ist. Dies kann so sein, dass das jeweilige Flachrohr von dem jeweiligen Schlitz im quer bzw. senkrecht zur Längsachse des Flachrohres gesehenen Querschnitt von außen umgriffen wird, und zwar so, dass zumindest ein den Schlitz begrenzender Abschnitt der Trennwand in eine Sicke des Flachrohrs eingreift. Beispielsweise kann vorgesehen sein, dass - wie oben erwähnt - an gegenüberliegenden Abschnitten der Flachrohrwand jeweils Sicken eingebracht sind und das Flachrohr mit einem Ende so in einen Schlitz der Trennwand eingeführt ist, dass gegenüberliegende, den Schlitz der Trennwand begrenzende Abschnitte der Trennwand sich in diesen Sicken erstrecken.In a particularly preferable embodiment, at least one coolant box has at least one partition, by means of which the interior of this coolant box is divided into separate sub-chambers, wherein in the partition slots are introduced, in each of which a flat tube is received. This is in particular such that the flat tube is inserted at a seen in its longitudinal direction end in a slot of the partition. This can be such that the respective flat tube is encompassed by the respective slot in the transverse or perpendicular to the longitudinal axis of the flat tube seen cross-section from the outside, in such a way that at least one slot limiting portion of the partition wall engages in a bead of the flat tube. For example, it may be provided that - as mentioned above - are each at opposite portions of the flat tube wall beads are introduced and the flat tube is inserted at one end into a slot of the partition that opposite, the slot of the partition wall delimiting sections of the partition extending in these beads.
Es kann vorgesehen sein, dass die Trennwand gegenüber den sich in ihre Schlitze erstreckenden Flachrohren in den Schlitzbereichen abgedichtet ist. Diese Abdichtung kann beispielsweise mittels Verlöten erreicht werden.It can be provided that the dividing wall is sealed off from the flat tubes extending into their slots in the slot areas. This seal can be achieved for example by means of soldering.
In diesem Zusammenhang sei angemerkt, dass der Heizkörper in besonders zu bevorzugender Ausgestaltung ein gelöteter Heizkörper ist. Der Heizkörper kann beispielsweise im Lotplattier-Verfahren verlötet sein. Der Heizkörper kann wenigstens eine Reihe gestapelter Flachrohre aufweisen, wobei die jeweils benachbarten Flachrohre beabstandet zueinander angeordnet sind und wobei in den damit gebildeten Zwischenräumen zwischen jeweils benachbarten Flachrohren Wellrippen für eine Luftdurchströmung vorgesehen sind. Dies kann beispielsweise so sein, dass die Wellrippen derart angeordnet sind, dass die Luftdurchströmung quer bzw. senkrecht zur Kühlmitteldurchströmung durch die Flachrohre erfolgt. Die Wellrippen können insbesondere so sein, dass sie die jeweils benachbarten Flachrohre kontaktieren. Die Wellrippen können beispielsweise mit den benachbarten Flachrohren jeweils verlötet sein.In this context, it should be noted that the radiator is in a particularly preferable embodiment, a brazed radiator. The radiator may be soldered, for example, in Lotplattier method. The radiator may comprise at least one row stacked flat tubes, wherein the respective adjacent flat tubes are spaced from each other and wherein in the spaces formed therebetween between adjacent flat tubes corrugated fins are provided for an air flow. This may for example be such that the corrugated fins are arranged such that the air flow is transverse or perpendicular to the coolant flow through the flat tubes. The corrugated ribs may in particular be such that they contact the respective adjacent flat tubes. The corrugated ribs may be soldered to the adjacent flat tubes, for example.
Es ist also insbesondere vorgesehen, dass sich die Flachrohre an den Wellrippen abstützen können bzw. umgekehrt.It is thus provided in particular that the flat tubes can be supported on the corrugated ribs or vice versa.
Der Heizkörper weist also vorzugsweise einen Rohr-Rippen-Block auf. In vorteilhafter Ausgestaltung sind die Flachrohre so angeordnet, dass ihre im Wesentlichen quer bzw. senkrecht zu ihren Höhen gelegenen bzw. sich in Längenrichtung und Breitenrichtung erstreckenden Flächen im Wesentlichen parallel zueinander ausgerichtet sind. Erfindungsgemäß ist die Wandstärke der Flachrohrwand im quer bzw. senkrecht zur Längsachse des Flachrohres betrachteten Querschnitt in den in Breitenrichtung gelegenen Endbereichen und in den sich, insbesondere beidseits, an die wenigstens eine Sicke anschließenden Bereichen größer ist als in den Bereichen, die sich in Breitenrichtung gesehen an die in Breitenrichtung gelegenen Endbereiche anschließen, und / oder größer ist als in den Bereichen, die sich in Breitenrichtung gesehen an die sich an die wenigstens eine Sicke anschließenden Bereiche anschließen und wobei die Flachrohre extrudierte Flachrohre sind. Sofern in Breitenrichtung zwei Sicken oder Sickenpaare vorgesehen sind, können in Breitenrichtung gelegene Bereiche wie folgt beschrieben werden: Erster Endbereich, erster Zwischenbereich, erster an eine erste Sicke angrenzender Bereich, erste Sicke, zweiter an die erste Sicke angrenzender Bereich, zweiter Zwischenbereich, erster an die zweite Sicke angrenzender Bereich, zweite Sicke, zweiter an die zweite Sicke angrenzender Bereich, zweiter Endbereich. Für drei, vier, fünf oder mehr in Breitenrichtung beabstandete Sicken bzw. Sickenpaare würden zwischen dem zweiten, an die zweite Sicke angrenzenden Bereich und dem Zwischenbereich, der an den zweiten Endbereich angrenzt, weitere Abfolgen von Zwischenbereich, an die i-te Sicke angrenzender erster Bereich, i-te Sicke, an die i-te Sicke angrenzender zweiter Bereich, gegeben sein, wobei i eine natürliche Zahl ist, die von drei bis n läuft, wobei n die Anzahl der in Breitenrichtung beabstandeten Sicken bzw.

Sämtliche Teile des Heizkörpers bestehen aus einer Aluminiumlegierung und sind miteinander verlötet. In Längsrichtung des Flachrohres 5 wird mittels der Sicken 32, 33 bzw. der die bildenden Abschnitte der Flachrohrwand eine Trennung 12 bewirkt, die als gestrichelte Linie dargestellt ist. Die Trennung 12 unterteilt das Flachrohr 5 in zwei Kammern bzw. Strömungskanäle, die in unterschiedlicher Richtung durchströmt werden.All parts of the radiator are made of an aluminum alloy and are soldered together. In the longitudinal direction of the

Die Luftströmungsrichtung ist durch die Pfeile L dargestellt, d. h. der Heizkörper 1 wird im Kreuzgegenstrom berieben: Das Kühlmittel strömt also zunächst auf der Leeseite (I) von oben nach unten durch den Heizkörper, wird dann entgegen der Luftströmungsrichtung, d. h. in der Tiefe, umgelenkt und strömt dann in einem zweiten Durchgang (II) auf der Luvseite des Heizkörpers 1 von unten nach oben. Diese Strömungsanordnung von Kühlmittel- und Luftstrom ist für hohe Leistung bevorzugt; es ist allerdings auch ein Kreuzgleichstrom möglich, d. h. die Luftströmungsrichtung L ist um 180° gedreht, d. h. sie würde in der

Das Flachrohr 5 weist Sicken 32, 33 auf. Die Sicke 32 wird von bzw. in einem Wandabschnitt 34 der Flachrohrwand 21 ausgebildet, und die Sicke 33 wird von bzw. in einem Wandabschnitt 34 gegenüberliegenden Wandabschnitt 35 der Flachrohrwand 21 ausgebildet. Die Sicken 32, 33 erstrecken sich entlang der gesamten Länge des Flachrohres 5 in dessen Längsrichtung 25.

Mittels der die Sicken 32, 33 bildenden Randabschnitte 34, 35 ist das Flachrohr 5 bzw. das Innere 22 des Flachrohrs 5 in die Strömungskanäle 23, 24 unterteilt, bzw. werden hierdurch die Strömungskanäle 23, 24 voneinander getrennt. Dies ist hier so, dass sich die Wandabschnitte 34, 35 auf ihren der einander zugewandten Seiten kontaktieren, wobei sie dort fluiddicht in Verbindung stehen.By means of the

Eine verhältnismäßig dickere Ausbildung der Wandstärke der Flachrohrwand 21 in den genannten Bereichen 38, 39, 40, 41 kann beispielsweise auch zweckmäßig sein, wenn der Innendruck bzw. der Druck des in den Kanälen 23, 24 strömenden Kühlmittels jeweils im Wesentlichen konstant ist bzw. wenn er in den jeweiligen jeweils senkrecht zur Strömungsrichtung bzw. Längsachse 25 gelegenen Querschnitten jeweils im Wesentlichen konstant ist. Trotz eines solchen im Wesentlichen konstanten Innendrucks bzw. eines Innendrucks, dessen Unterschiede als vernachlässigbar angesehen werden können, können nämlich in der Flachrohrwand 21 im senkrecht zur Längsachse 25 betrachteten Querschnitt entlang der Flachrohrwand 21 unterschiedliche Spannungen gegeben sein.

Während bei den aus dem Stand der Technik bekannten Gestaltungen die Wandstärkenauslegung auf die Stelle der höchsten Beanspruchung ausgelegt werden und die restlichen Stellen der Wände überdimensioniert sind, ist erfindungsgemäß vorgesehen, dass extrudierte Flachrohre mit spezieller Auslegung der Flachrohrwandstärke eingesetzt werden (vgl.
Ferner muss bei der Gestaltung gemäß dem Ausführungsbeispiel die Verlötung der Sicke nicht mehr gewährleistet werden - was im Stand der Technik erforderlich ist - da diese bereits im Extrudierprozess ausgebildet werden kann bzw. ausgebildet wird.

While in the designs known from the prior art, the wall thickness design are designed for the highest stress location and the remaining locations of the walls are oversized, the invention provides that extruded flat tubes are used with special design of the flat tube wall thickness (see.
Furthermore, in the embodiment according to the embodiment, the soldering of the bead must not be guaranteed - which in the prior art is required - since this can already be formed in the extrusion process or is formed. In the prior art, however, inevitably an increased use of material and an increased cost situation is given, which can be avoided at least by the designs according to the embodiments of the invention.
Wie angesprochen zeigen die
Die Sicken 32, 33 können in den Gestaltungen gemäß den
Wie das Ausführungsbeispiel verdeutlicht, können mit einer erfindungsgemäßen Gestaltung ein geringes Gewicht sowie bessere Ergebnisse bei Innendruckbeanspruchungen erreicht werden.As the embodiment illustrates, with a design according to the invention, a low weight and better results in internal pressure stresses can be achieved.
Der Einsatz extrudierter Flachrohre bei Heizkörpern kann ferner zu geringeren Investitionskosten für den Maschinenpark führen. Es ist nämlich möglich, bei konstanter Außengeometrie der Flachrohre verschiedene Innengeometrien zu realisieren, um auf unterschiedliche Anforderungen leicht reagieren zu können. Dies kann beispielsweise so sein, dass verschiedene Fahrzeugtypen, wie PKW und NKW bzw. für verschiedene Kraftfahrzeugmotoren bei den in Rede stehenden Heizkörpern Flachrohre verwendet werden, die jeweils die gleiche Außengeometrie aufweisen. Die Innengeometrie kann dabei jeweils an den speziellen Anwendungsfall angepasst ausgebildet sein, was sich im Extrudierprozess gut realisieren lasst.The use of extruded flat tubes in radiators can also lead to lower investment costs for the machinery. It is namely possible to realize different internal geometries with a constant outer geometry of the flat tubes in order to be able to react easily to different requirements. This can for example be such that different types of vehicles, such as cars and commercial vehicles or for various motor vehicle engines in the radiators in question flat tubes are used, each having the same outer geometry. The internal geometry can in each case be adapted to the specific application, which can be realized well in the extrusion process.
Folglich können Investitionskosten für zusätzliche oder viele Rollensätze bei Spezialanwendungen entfallen, wie zum Beispiel für die Anwendung im NKW-Bereich für einen Heizkörper mit hoher Innendruckbeanspruchung.Consequently, investment costs for additional or many sets of rollers in special applications can be omitted, such as for use in the commercial vehicle sector for a radiator with high internal pressure.
Anzumerken ist, dass selbstverständlich auch Ausführungsformen unter die Erfindung fallen, bei denen die angesprochenen Vorteile nicht oder nur teilweise gegeben sind. Die angesprochenen Vorteile sind also solche, die die Erfindung, zumindest in bevorzugten Weiterbildung, ermöglicht.It should be noted that, of course, embodiments fall under the invention, in which the advantages mentioned are not or only partially given. The mentioned advantages are therefore those which the invention makes possible, at least in a preferred development.
