- the invention relates to a heat exchanger, in particular for motor vehicles for a first and a second flow medium, in particular according to the preamble of claim 1.
- this temperature threshold up to about 260 to 270 degrees Celsius, aluminum manifolds are used for intercoolers, which are more temperature-resistant. If you want to continue to use these conventional charge air cooler, ie at increased boost pressures and charge air temperatures, you need a pre-cooler, ie the charge air is cooled down in two stages, to preferably less than about 260 degrees through the precooler. This must therefore be particularly temperature resistant.
- the charge air is cooled in the intercooler of motor vehicles usually by ambient air, wherein the intercooler is arranged in the front engine compartment of the motor vehicle in the region of a coolant / air cooler.
- the coolant of the cooling circuit of the internal combustion engine cools the charge air.
- a disadvantage of known charge air coolers is the deflection of the charge air in the air boxes, which leads to a pressure drop.
- Other constructions, z. B. plate or stacked disk heat exchanger according to DE-A 195 11 991 have due to the double 90 degree deflection of the charge air on an increased pressure loss.
- the tube bundle and one of the two tubesheets are integrally formed and produced by the extrusion molding method known per se.

- the remaining parts such as the second tube sheet, the housing and the connecting pieces are made of aluminum materials and are conventionally connected to the extrusion, z. B. by soldering or welding. It is also advantageous that any pipe cross section, be it produced in round or square shape by the extrusion. It is also advantageous that the tubes of the tube bundle can be produced in any length and wall thickness. The temperature resistance is also achieved by a low-stress geometry of the Ganzaluminium Anlagenübertragers invention.
- the housing is produced by extrusion, d. H. in one operation with the tubesheet and the tube bundle.
- the transition region between the tubes and the tubesheets is designed round, ie provided with a radius.
- the transition radius is preferably arranged on the tube outer side, but can also be provided in the inflow region of the tube on the tube plate. The latter would further reduce the primary-side pressure drop.
- the heat exchanger according to the invention is used as a charge air cooler for internal combustion engines of motor vehicles, as a pre or intercooler of a charging system.
- a charge air cooler for internal combustion engines of motor vehicles as a pre or intercooler of a charging system.
- Fig. 1 shows in exploded view a charge air cooler 1 for an internal combustion engine, not shown, of a motor vehicle.
- the intercooler 1 consists of the following parts, from left to right in the drawing: an inlet nozzle 2, a tube bundle 3 with tube sheet 4, designed as a housing shell, cylindrical housing 5 and an outlet nozzle 6.
- the tube bundle 3 consists of a plurality of tubes 3a , which are formed integrally with the tube sheet 4 and each having a rectangular flow cross-section 3b.
- the tubesheet 4 and the adjoining tubes 3a are made by extrusion, ie, a process similar to extruding or extrusion molding.
- the starting material used is an aluminum extruded alloy, which is pressed by a die, not shown, with the geometry and the arrangement of the tubes 3a.
- the cross section of the tubes 3a and their length and wall thickness can be freely selected by the extrusion process or the corresponding die.

- the tube bundle 3 has a side facing away from the tube bottom 4 end face 3c, which is provided in a conventional manner with a second tube plate, not shown. All parts, preferably made of aluminum alloys exist are soldered together to form a complete heat exchanger.
- the housing shell 5 has on its circumference an inlet nozzle 7 and this diagonally opposite to an outlet nozzle 8 - thus, a cooling chamber 9 is formed between the two tube sheets and the housing shell 5, which can be flowed through by the coolant of a non-illustrated cooling circuit of the internal combustion engine.
- the coolant thus flows between the tubes 3a and around the tube bundle 3.
- the hot charge air represented by an arrow LL, enters into the inlet connection 2, which is designed in the manner of a diffuser and thus distributes the charge air evenly to the surface of the tube bottom 4 and the individual tube cross-sections 3b.
- the charge air flows through all the tubes 3a of the tube bundle 3 and exits on the opposite side 3c from the tube bundle 3 and into the outlet nozzle 6.
- the fully assembled intercooler 1 is inserted into a charge air line, not shown, which is flush with the inlet nozzle 2 and the outlet nozzle 6.

Both intercoolers are all-aluminum radiators and thus withstand charge air temperatures of up to more than 300 degrees Celsius, which is also achieved by a voltage-optimized design. In the case of pre-cooling, the charge air is pre-cooled to about 260 degrees and can then be fed to a conventional intercooler for further cooling.

Description
Die Erfindung betrifft einen Wärmeübertrager, insbesondere für Kraftfahrzeuge für ein erstes und ein zweites Strömungsmedium insbesondere nach dem Oberbegriff des Patentanspruches 1.The invention relates to a heat exchanger, in particular for motor vehicles for a first and a second flow medium, in particular according to the preamble of claim 1.
Brennkraftmaschinen für Kraftfahrzeuge werden zur Erhöhung ihrer Leistung aufgeladen, wobei die Ladeluft nach ihrer Verdichtung im Lader zwecks Erhöhung des Liefergrades durch einen Ladeluftkühler gekühlt wird. Die Entwicklung moderner Verbrennungsmotoren geht in Richtung höherer Leistung und dabei auch in Richtung höherer Ladedrücke, was insbesondere durch verbesserte Lader, z. B. so genannte VTG-Lader (variable Turbinengeometrie) möglich wird. Teilweise erfolgt auch eine zweistufige Aufladung, wobei zwischen beiden Stufen eine Zwischenkühlung der Ladeluft vorgesehen ist. Demnach benötigen derartige Ladeluftsysteme einen Zwischen-Ladeluftkühler. Durch die verstärkte Aufladung werden erhöhte Ladelufttemperaturen erreicht, die mit herkömmlichen Ladeluftkühlern nicht mehr beherrschbar sind. Bekannte Ladeluftkühler weisen z. T. Kunststoffsammelkästen auf, die jedoch nur bis zu Temperaturen von ca. 200 Grad Celsius einsetzbar sind. Oberhalb dieser Temperaturschwelle bis zu etwa 260 bis 270 Grad Celsius werden Aluminium-Sammelkästen für Ladeluftkühler verwendet, die temperaturbeständiger sind. Will man diese herkömmlichen Ladeluftkühler weiter verwenden, d. h. bei erhöhten Ladedrücken und Ladelufttemperaturen, benötigt man einen Vorkühler, d. h. die Ladeluft wird in zwei Stufen heruntergekühlt, und zwar auf vorzugsweise unter etwa 260 Grad durch den Vorkühler. Dieser muss daher besonders temperaturbeständig sein.Internal combustion engines for motor vehicles are charged to increase their power, the charge air is cooled after its compression in the loader in order to increase the degree of delivery by a charge air cooler. The development of modern internal combustion engines goes in the direction of higher power and also in the direction of higher boost pressures, which in particular by improved loader, z. B. so-called VTG loader (variable turbine geometry) is possible. In some cases, there is also a two-stage charging, between two stages, an intermediate cooling of the charge air is provided. Accordingly, such charge air systems require an intermediate intercooler. Increased charging results in increased charge air temperatures that are no longer manageable with conventional intercoolers. Known intercoolers have z. T. plastic collection boxes, which, however, can only be used up to temperatures of about 200 degrees Celsius. Above this temperature threshold, up to about 260 to 270 degrees Celsius, aluminum manifolds are used for intercoolers, which are more temperature-resistant. If you want to continue to use these conventional charge air cooler, ie at increased boost pressures and charge air temperatures, you need a pre-cooler, ie the charge air is cooled down in two stages, to preferably less than about 260 degrees through the precooler. This must therefore be particularly temperature resistant.
Die Ladeluft wird im Ladeluftkühler von Kraftfahrzeugen in der Regel durch Umgebungsluft gekühlt, wobei der Ladeluftkühler im vorderen Motorraum des Kraftfahrzeuges im Bereich eines Kühlmittel/Luftkühlers angeordnet ist. Teilweise sind jedoch auch Ladeluftkühler mit Flüssigkeitskühlung im Einsatz, wobei das Kühlmittel des Kühlkreislaufes der Brennkraftmaschine die Ladeluft kühlt. Nachteilig bei bekannten Ladeluftkühlem (vgl.
Auf dem Gebiet der Abgaswärmeübertrager wurden Bauweisen bekannt, bei welchen der Druckverlust auf der Primärseite durch Vermeidung von Umlenkungen reduziert wurde, z. B. durch die
Es ist Aufgabe der vorliegenden Erfindung, einen Wärmeübertrager der eingangs genannten Art zu schaffen, der eine Temperaturbeständigkeit bis etwa 300 Grad Celsius und gegebenenfalls darüber und einen vorzugsweise relativ niedrigen Druckabfall auf der Gasseite aufweist sowie vorzugsweise mit geringen Kosten herstellbar ist.It is an object of the present invention to provide a heat exchanger of the type mentioned, which has a temperature resistance up to about 300 degrees Celsius and optionally above and a preferably relatively low pressure drop on the gas side and is preferably produced at low cost.
Diese Aufgabe wird durch die Merkmale des Patentanspruches 1 gelöst. Erfindungsgemäß ist vorgesehen, dass das Rohrbündel und einer der beiden Rohrböden einstückig ausgebildet und durch das an sich bekannte Fließpressverfahren herstellbar sind. Das Fließpressen ist eine bekannte Technologie, ähnlich dem Extrudieren und Strangpressen, wobei ein Rohteil durch ein formgebendes Werkzeug (Matrize) hindurchgedrückt wird (vgl. Dubbel, Taschenbuch für den Maschinenbau, 20. Auflage, S30). Als Werkstoff wird bevorzugt eine Aluminiumstrangpresslegierung verwendet, die sich für das Fließpressen besonders eignet. Das dermaßen durch Fließpressen hergestellte Erzeugnis ist ein fertiger Rohrboden, an welchen sich sämtliche Rohre des Rohrbündels nahtlos und einstückig anschließen. Damit wird der Vorteil erreicht, dass erstens das separate Herstellen des Rohrbodens und der Rohre sowie zweitens die aufwendige Verbindung zwischen Rohren und Rohrböden, z. B. Schweißen oder Löten entfallen. Damit werden die Herstellkosten erheblich reduziert. Die übrigen Teile wie der zweite Rohrboden, das Gehäuse und die Anschlussstutzen bestehen aus Aluminiumwerkstoffen und werden konventionell mit dem Fließpressteil verbunden, z. B. durch Löten oder Schweißen. Vorteilhaft ist ferner, dass jeder beliebige Rohrquerschnitt, sei es in runder oder eckiger Form durch das Fließpressen herstellbar ist. Ferner ist von Vorteil, dass die Rohre des Rohrbündels in beliebiger Länge und Wandstärke herstellbar sind. Die Temperaturfestigkeit wird auch durch eine spannungsarme Geometrie des erfindungsgemäßen Ganzaluminiumwärmeübertragers erreicht.This object is solved by the features of claim 1. According to the invention it is provided that the tube bundle and one of the two tubesheets are integrally formed and produced by the extrusion molding method known per se. Extrusion molding is a known technology, similar to extrusion and extrusion, with a blank being forced through a forming die (see FIG. Dubbel, paperback for mechanical engineering, 20th edition, S30). The material used is preferably an aluminum extrusion alloy which is particularly suitable for extrusion. The product thus produced by extrusion is a finished tube sheet, to which all tubes of the tube bundle connect seamlessly and in one piece. Thus, the advantage is achieved that, firstly, the separate production of the tube plate and the tubes, and second, the complex connection between pipes and tube sheets, for. As welding or soldering omitted. This considerably reduces the production costs. The remaining parts such as the second tube sheet, the housing and the connecting pieces are made of aluminum materials and are conventionally connected to the extrusion, z. B. by soldering or welding. It is also advantageous that any pipe cross section, be it produced in round or square shape by the extrusion. It is also advantageous that the tubes of the tube bundle can be produced in any length and wall thickness. The temperature resistance is also achieved by a low-stress geometry of the Ganzaluminiumwärmeübertragers invention.
Nach einer vorteilhaften Ausgestaltung der Erfindung ist auch das Gehäuse durch Fließpressen herstellbar, d. h. in einem Arbeitsgang mit dem Rohrboden und dem Rohrbündel. Damit wird der Vorteil einer weiteren Herstellungsvereinfachung und Kostenreduzierung des erfindungemäßen Wärmeübertragers erreicht. Mit dem Fließteil werden zur Komplettierung des Wärmeübertragers nur noch der zweite Rohrboden und die Anschlussstutzen verbunden.According to an advantageous embodiment of the invention, the housing is produced by extrusion, d. H. in one operation with the tubesheet and the tube bundle. Thus, the advantage of further manufacturing simplification and cost reduction of erfindungemäßen heat exchanger is achieved. With the flow part, only the second tubesheet and the connecting pieces are connected to complete the heat exchanger.
Nach einer vorteilhaften Ausgestaltung der Erfindung ist der Übergangsbereich zwischen den Rohren und den Rohrböden rund gestaltet, d. h. mit einem Radius versehen. Damit werden der Vorteil einer erhöhten Festigkeit durch einen günstigen Faserverlauf und der Vorteil eines besseren Fließverhaltens des Materials erreicht. Der Übergangsradius ist vorzugsweise auf der Rohraußenseite angeordnet, kann jedoch auch im Einströmbereich des Rohres am Rohrboden vorgesehen werden. Letzteres würde den primärseitigen Druckabfall weiter verringern.According to an advantageous embodiment of the invention, the transition region between the tubes and the tubesheets is designed round, ie provided with a radius. Thus, the advantage of increased strength achieved by a favorable fiber flow and the advantage of better flow behavior of the material. The transition radius is preferably arranged on the tube outer side, but can also be provided in the inflow region of the tube on the tube plate. The latter would further reduce the primary-side pressure drop.
Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung wird der erfindungsgemäße Wärmeübertrager als Ladeluftkühler für Verbrennungsmotoren von Kraftfahrzeugen eingesetzt, und zwar als Vor- oder Zwischenkühler eines Aufladesystems. Damit ist eine kostengünstige Lösung geschaffen, die auch bei hohen Aufladedrücken und dementsprechend hohen Temperaturen eine wirksame Kühlung der Ladeluft erlaubt und gleichzeitig die Weiterverwendung konventioneller Ladeluftkühler ermöglicht.According to a further advantageous embodiment of the invention, the heat exchanger according to the invention is used as a charge air cooler for internal combustion engines of motor vehicles, as a pre or intercooler of a charging system. For a cost-effective solution is created, which allows effective cooling of the charge air even at high Aufladedrücken and correspondingly high temperatures and at the same time allows the further use of conventional intercooler.
