Description

Die Erfindung betrifft eine Kühleranordnung, bestehend aus je zwei Sammelkästen aufweisenden Kühlern, zur Kühlung verschiedener Fluide, deren in mindestens einer Reihe angeordnete, die Sammelkästen verbindende Flachrohre quer zur Lüfterachse des im Inneren der Kühleranordnung angeordneten Radialventilators verlaufen, mit einer Frontwand und einer Rückwand sowie mit Zu - und Ablauf und mit Zu - und Ablaufleitungen für durch mindestens zwei Kühler strömendes Fluid, die an Sammelkästen angeschlossen sind.The invention relates to a cooler arrangement, each consisting of two header boxes having coolers, for cooling various fluids, whose in at least one Row of flat tubes connecting the header boxes across the fan axis of the radial fan arranged inside the cooler arrangement run with a front wall and a rear wall as well as with inlet and outlet and with inlet and outlet Drain lines for fluid flowing through at least two coolers Collection boxes are connected.

Die Kühleranordnung geht aus der bisher unveröffentlichten Patentanmeldung DE 199 50 753.8 der Anmelderin hervor.The cooler arrangement is based on the previously unpublished patent application DE 199 50 753.8 by the applicant.

Die Zu - und Abflußleitungen sind dort relativ flach und damit platzsparend ausgebildet. Sie verbinden in der dortigen Fig. 1 die beiden seitlichen und den unten angeordneten Kühler, die dort Kühlflüssigkeitskühler sind. Der Ein - bzw. der Austritt der Zu - oder Abflußleitungen in bzw. aus dem Sammelkasten erfolgt dort über die Stirnseiten des Sammelkastens. Der Zulauf und der Ablauf der Kühlflüssigkeit befinden sich an der Rückwand. Mit einer solchen Ausbildung kann nicht allen Einsatz - bzw. Anschlußbedingungen entsprochen werden.The inflow and outflow lines are relatively flat there and therefore save space educated. They connect the two side and the bottom in Fig. 1 there arranged coolers, which are coolant coolers there. Entry and exit the inflow or outflow lines in or out of the collection box are carried out there via the End faces of the collection box. The inlet and outlet of the coolant are on the back wall. With such training, not everyone can Operating and connection conditions are met.

Die Aufgabe der Erfindung besteht darin, die Kühleranordnung so auszubilden, daß sie für andere Einsatz - bzw. Anschlußbedingungen geeignet ist, wobei die kompakte und raumsparende Gestalt erhalten bleiben soll und ein effizienter Wärmeaustausch in den mit den Zu - und Abflußleitungen verbundenen Kühlern stattfinden kann.The object of the invention is to design the cooler arrangement so that it is suitable for other conditions of use or connection, the compact and space-saving design should be retained and an efficient one Heat exchange in the coolers connected to the inlet and outlet pipes can take place.

Die erfindungsgemäße Lösung besteht darin, daß der eine Zu - oder Ablauf an der Rückseite, vorzugsweise in einem Eckbereich der Rückwand, und der andere Zu-oder Ablauf an der Frontseite, vorzugsweise im dazu diagonalen Eckbereich der Frontwand, angeordnet ist, wobei die Länge und der Querschnitt der Zu - und Ablaufleitungen für jeden angeschlossenen Kühler etwa gleich ist und die Zu - und Ablaufleitungen baukastenartig zusammensteckbar sind.The solution according to the invention is that the one inlet or outlet at the Rear, preferably in a corner area of the rear wall, and the other zu-or Drain on the front, preferably in the diagonal corner area of the Front wall, is arranged, the length and the cross section of the inlet and outlet Drain lines for each connected cooler is approximately the same and the inlet and outlet Drain lines are modularly pluggable.

Die erfindungsgemäße Anordnung der Zu - und Abläufe gewährleistet eine gleichmäßige Verteilung der Kühlmittelmenge auf die Kühler, ohne Regulierungselemente in den Leitungen anordnen zu müssen. Die Länge der Zu-und Ablaufleitungen zu und von den Kühlern ist zumindest etwa gleich groß. Somit sind die Strömungswiderstände etwa gleich, was dazu führt, daß alle angeschlossenen Kühler in etwa gleich große Kühlmittelmengen erhalten und in allen angeschlossenen Kühlern gleich große Temperaturunterschiede zwischen der Kühlluft und der Kühlflüssigkeit vorliegen, wodurch ein effizienter Wärmeaustausch erreicht ist.The arrangement of the inlets and outlets according to the invention ensures a even distribution of the amount of coolant to the cooler without To have to arrange regulatory elements in the lines. The length of the Zu and Drain lines to and from the coolers are at least approximately the same size. Consequently the flow resistances are about the same, which means that all connected cooler in about the same amount of coolant and in all connected coolers equal temperature differences between the Cooling air and the coolant are present, creating an efficient heat exchange is reached.

Die erfindungsgemäße Kühleranordnung ist für verschiedenartige Anschlußvarianten geeignet, die einen Zu - oder Ablauf an der Frontwand und den anderen Zu - oder Ablauf an der Rückwand erfordern. Wegen der baukastenartigen Zusammensteckbarkeit der Zu - und Ablaufleitungen können unterschiedliche Schaltungsvarianten wirtschaftlich unter Verwendung vieler Gleichteile realisiert werden.The cooler arrangement according to the invention is for different types of connection Suitable, the one inlet or outlet on the front wall and the other inlet or Require drain on the rear wall. Because of the modular The inlet and outlet lines can be plugged together differently Circuit variants implemented economically using many identical parts become.

Die Zu - oder Abflußleitungen weisen einen flachen, vorzugsweise rechteckigen, Querschnitt auf, wodurch die Kühleranordnung kompakt bleibt. Sie bestehen aus Krümmern, Muffen, T - Stücken und Kreuzstücken aus Kunststoff - Spritzguss und aus geraden und/oder gebogenen Leitungsabschnitten, vorzugsweise aus Aluminium, beispielsweise als Strangpressprofil hergestellt.The inflow or outflow lines have a flat, preferably rectangular, Cross section on, whereby the cooler arrangement remains compact. they consist of Elbows, sleeves, T - pieces and cross pieces made of plastic injection molding and from straight and / or curved line sections, preferably from Aluminum, for example manufactured as an extruded profile.

Gemäß Anspruch 4, der sich auf die Schaltungsvariante für drei Kühler bezieht, besitzt der Zu - oder Ablauf an der Rückwand zwei lange Zu - oder Ablaufleitungen zum Ein - oder Austritt zweier Kühler und eine kurze Zu - oder Ablaufleitung zum dritten Kühler und der Zu - oder Ablauf an der Frontwand besitzt eine lange Zu-oder Ablaufleitung und zwei kurze Zu - oder Ablaufleitungen, wobei die Länge der Zu -oder Ablaufleitungen für alle drei Kühler etwa gleich ist.According to claim 4, which relates to the circuit variant for three coolers, the inlet or outlet on the rear wall has two long inlet or outlet lines for the entry or exit of two coolers and a short inlet or outlet line for the third cooler and the inlet or outlet on the front wall has a long inlet or Drain line and two short inlet or outlet lines, the length of the inlet -or drain lines for all three coolers is approximately the same.

Im Gegensatz dazu schreibt Anspruch 5 für zwei Kühler vor, daß der Zu - oder Ablauf an der Rückwand eine lange und eine kurze Zu - oder Ablaufleitung aufweist und der Zu - oder Ablauf an der Frontwand ebenfalls, wobei die Länge der Zu - oder Ablaufleitungen zweier Kühler etwa gleich ist.In contrast, claim 5 stipulates for two coolers that the inlet or outlet Drain on the rear wall has a long and a short inlet or outlet pipe and the inlet or outlet on the front wall as well, the length of the inlet or outlet Drain lines of two coolers is approximately the same.

Die Kühleranordnung ist kastenförmig ausgebildet und für Kraftfahrzeuge vorgesehen. In den Fig. 1 und 2 ist der obere Kühler 1, ein Ladeluftkühler und die beiden seitlichen Kühler 2 und 4 sowie der untere Kühler 3 der Kühleranordnung zu erkennen, sowie ein von der Kühleranordnung eingeschlossener Radialventilator 7 mit einer Ventilatorachse V. Die Kühleranordnung hat eine Frontwand F und eine Rückwand R. Die Flachrohre 8 sämtlicher Kühler 1, 2, 3, 4 verlaufen quer zur Ventilatorachse V. Sie wurden in Fig. 1 lediglich im seitlichen Kühler 2 teilweise eingezeichnet. An der Rückwand R befinden sich Zu - oder Ablaufleitungen L und an der Frontwand F ebenfalls. Die Kühler 2, 3 und 4 sind Kühlflüssigkeitskühler, die mittels der Zu - und Ablaufleitungen L verbunden sind. In den Fig. 1 und 2 wurden Pfeile 6 eingezeichnet, welche die Durchströmungsrichtung der Leitungen L und der Kühler 2, 3 in den Flachrohren 8 anzeigen. Die Flachrohre 8 verlaufen also in Richtung der in den Fig. in den Kühlern 2, 3 und 4 eingezeichneten Pfeile 6 und damit quer zur in Fig. 1 eingezeichneten Vertilatorachse V. Der Zulauf Z der Kühlflüssigkeit ist im Eckbereich E an der Rückwand R angeordnet. (Fig. 1) Der Ablauf A befindet sich im diagonalen Eckbereich E an der Frontwand F. (Fig. 2) Wie aus der Fig. ferner zu sehen ist, haben die Kühler 1, 2, 3 und 4 jeweils zwei Sammelkästen 5, wobei jeweils zwei Sammelkästen 5 benachbarter Kühler 1 und 2, 2 und 3 sowie 4 und 1 eine Kante der Kühleranordnung ausbilden, wo sie eng aneinanderliegen, um die Kühleranordnung abzuschließen und dadurch die vom Radialventilator 10 (Fig. 7) angesaugte Kühlluft zwingen, zwischen den Flachrohren 8 der Kühler hindurchzuströmen. Aus den Fig. 1 bis 6 sind die aneinanderliegenden Sammelkästen 5 zu erkennen. Die Zu - oder Ablaufleitungen L haben einen etwa rechteckigen Querschnitt. Ihre Länge ist etwa gleich - auf jeden einzelnen Kühler bezogen. In Fig. 1 führt die vertikale Zu - oder Ablaufleitung L zum Kühler 3 und die horizontale zum Kühler 5. Die Längen der Zu - oder Ablaufleitungen L dieser beiden Kühler 3 und 5 sind etwa gleich. Aus Fig. 2 geht hervor, daß die längere gebogene Leitung 12 dem Kühler 2 zugeordnet ist, so daß insgesamt für jeden Kühler 2, 3, 4 etwa gleiche Leitungslängen vorliegen. The cooler arrangement is box-shaped and is intended for motor vehicles. 1 and 2, the upper cooler 1, a charge air cooler and the two side coolers 2 and 4 and the lower cooler 3 of the cooler arrangement can be seen, as well as a radial fan 7 enclosed by the cooler arrangement with a fan axis V. The cooler arrangement has a front wall F and a rear wall R. The flat tubes 8 of all coolers 1, 2, 3, 4 run transversely to the fan axis V. They were only partially drawn in in FIG. 1 in the side cooler 2 . There are inlet or outlet lines L on the rear wall R and also on the front wall F. The coolers 2, 3 and 4 are coolant coolers which are connected by means of the inlet and outlet lines L. 1 and 2, arrows 6 have been drawn in, which indicate the direction of flow through the lines L and the coolers 2, 3 in the flat tubes 8 . The flat tubes 8 thus run in the direction of the arrows 6 shown in the figures in the coolers 2, 3 and 4 and thus transversely to the Vertilatorachse V shown in FIG. 1. The inlet Z of the cooling liquid is arranged in the corner region E on the rear wall R. (Fig. 1) The drain A is located in the diagonal corner area E on the front wall F. (Fig. 2) As can also be seen from the figure, the coolers 1, 2, 3 and 4 each have two collecting tanks 5, whereby two collecting boxes 5 of adjacent coolers 1 and 2, 2 and 3 as well as 4 and 1 form an edge of the cooler arrangement where they lie closely together in order to close off the cooler arrangement and thereby force the cooling air sucked in by the radial fan 10 (FIG. 7) between the flat tubes 8 the cooler to flow through. 1 to 6 show the collecting boxes 5 lying one against the other. The inlet or outlet lines L have an approximately rectangular cross section. Their length is about the same - related to each individual cooler. In FIG. 1, the vertical inlet or outlet line L leads to the cooler 3 and the horizontal one to the cooler 5. The lengths of the inlet or outlet lines L of these two coolers 3 and 5 are approximately the same. From Fig. 2 it can be seen that the longer curved line 12 is assigned to the cooler 2 , so that overall there are approximately the same line lengths for each cooler 2, 3, 4 .

Bezug nehmend auf die Fig. 1 bis 6 kann erkannt werden, daß die Zu- oder Abflußleitungen L aus geraden Leitungsabschnitten 11, aus gebogenen Leitungsabschnitten 12, aus Krümmern 13 und Kreuzstücken 14 bestehen, die mittels Anschlußmuffen 15 verbunden sind. Sie sind unter Verwendung von Dichtungen 16 zusammensteckbar. Die geraden und gebogenen Leitungsabschnitte 11; 12 bestehen aus stranggepreßten Aluminiumprofilen. Die Krümmer 13 sowie die Kreuzstücke 14 sind Kunststofformteile. Mit einer solchen Ausbildung lassen sich beliebige Schaltungsvarianten, d. h. strömungstechnische Verbindungen mehrerer Kühler, kostengünstig realisieren.With reference to FIGS. 1 to 6, it can be seen that the inflow or outflow lines L consist of straight line sections 11, of curved line sections 12, of elbows 13 and cross pieces 14 which are connected by means of connecting sleeves 15 . They can be plugged together using seals 16 . The straight and curved line sections 11; 12 consist of extruded aluminum profiles. The manifold 13 and the cross pieces 14 are molded plastic parts. With such a design, any circuit variants, ie fluidic connections of several coolers, can be implemented inexpensively.

In der in den Fig. 3 und 4 gezeigten Schaltungsvariante ist der seitliche Kühler 2 und der untere Kühler 3 mittels der Zu - und Ablaufleitungen L verbunden. Diese sind ebenfalls als Kühlflüssigkeitskühler vorgesehen. Der andere seitliche Kühler 4 kann z. B. der Ölkühlung dienen. Die vertikale Leitung L in Fig. 3 führt zum unteren Kühler 3. Am Zulauf Z ist ein Kreuzstück 14 (Fig. 7) angeordnet, damit die Kühlflüssigkeit über einen kurzen Leitungsansatz auch zum seitlichen Kühler 2 gelangen kann. Die Fig. 4 zeigt, daß die längere, gebogene Leitung 12 vom seitlichen Kühler 2 zum Auslauf A führt. Auch hier sind die jedem Kühler 2 und 3 zugeordneten Längen der Zu - oder Ablaufleitungen L etwa gleich. Ein Zu - oder Ablauf Z, A ist in einem Eckbereich E der Rückwand R und der andere Zu - oder Ablauf Z, A ist im diagonalen Eckbereich E der Frontwand F zu finden. Diese allen Varianten gemeinsamen Merkmale besitzt auch das Ausführungsbeispiel aus den Fig. 5 und 6, bei dem die beiden seitlichen Kühler 2 und 4 miteinander verbunden sind. In Fig. 5 wurde die Rückwand R nicht gezeichnet und in Fig. 6 die Frontwand F ebenfalls weggelassen. Dadurch wird der Radialventilator 7, der sich im Inneren der Kühleranordnung befindet sichtbar.In the circuit variant shown in FIGS. 3 and 4, the side cooler 2 and the lower cooler 3 are connected by means of the inlet and outlet lines L. These are also provided as coolant coolers. The other side cooler 4 can, for. B. serve the oil cooling. The vertical line L in FIG. 3 leads to the lower cooler 3. A cross piece 14 (FIG. 7) is arranged at the inlet Z so that the cooling liquid can also reach the side cooler 2 via a short line attachment. Fig. 4 shows that the longer, curved line 12 leads from the side cooler 2 to the outlet A. Here, too, the lengths of the inlet or outlet lines L assigned to each cooler 2 and 3 are approximately the same. One inlet or outlet Z, A can be found in a corner area E of the rear wall R and the other inlet or outlet Z, A can be found in the diagonal corner area E of the front wall F. These features common to all variants also have the exemplary embodiment from FIGS. 5 and 6 in which the two side coolers 2 and 4 are connected to one another. The rear wall R has not been drawn in FIG. 5 and the front wall F has also been omitted in FIG. 6. This makes the radial fan 7, which is located inside the cooler arrangement, visible.

In Fig. 7 ist ein als Spritzgussteil herstellbares T -Stück 14 abgebildet und in Fig. 8 eine Zu - oder Ablaufleitung L. Das Kreuzstück hat einen runden Zu - oder Ablaufanschluß und drei flache Abzweige, die mittels der Muffen 16 (Fig.8) mit den Krümmern 13 oder den geraden 11 oder gebogenen Leitungsabschnitten 12 je nach Bedarf zusammengesteckt werden können. Dazu werden Dichtungen 16 verwendet.FIG. 7 shows a T-piece 14 which can be produced as an injection molded part and FIG. 8 shows an inlet or outlet line L. The cross piece has a round inlet or outlet connection and three flat branches which are connected by means of the sleeves 16 (FIG. 8). can be plugged together with the elbows 13 or the straight 11 or curved line sections 12 as required. Seals 16 are used for this.
