- the solution according to the invention allows the cooling network to expand in the longitudinal direction of the flat tubes.
- the elasticity achieved in this area by the fold ensures additional safety.
- elongated holes in the side panels are no longer necessary. However, they can be provided, to a certain extent, in addition. Threading screws are inserted through the holes, which are used to connect the side parts to the plastic water tanks on the opposite tank.
- the screws used for this purpose have a collar formed on the screw head, the diameter of which is slightly smaller than the small diameter of the elongated hole or the hole diameter and the thickness of which corresponds to the thickness of the side part.
- the assembly process was simplified in that the side parts in both Longitudinal direction of the plastic boxes as well as perpendicular to it, i.e. from above the cooler can be brought up. This is especially true in tight spaces Conditions of importance.

Description
Die Erfindung betrifft einen Wasser/Luft-Kühler für Verbrennungskraftmaschinen,
insbesondere für Nutzfahrzeuge mit den Merkmalen des Oberbegriffes im Anspruch
1.
Der so ausgebildete Wasser/Luft-Kühler ist aus dem EP 504 034 bekannt. Bei
dem bekannten Wasser/Luft-Kühler sind sämtliche Verbindungen der Seitenteile
mit den Kunststoffwasserkästen mittels gewindeschneidender Schrauben ausgeführt.
Die Schraubarbeitsgänge sind zeitaufwendig und jede Schraube stellt ein
Einzelteil dar, daß bereitgestellt werden muß.
Deshalb gibt es Lösungen, wie z.B. diejenigen aus EP 346 602 und EP 504 635,
die ohne Schraubverbindungen auskommen. Dafür sind formschlüssige Verbindungen
vorgesehen, die aus am Kunststoffwasserkasten angeformte Zapfen
bestehen, die in Öffnungen der Seitenteile einrasten. In dem erstgenannten Dokument
sind an jedem Kastenende vier Zapfen angeformt worden, wodurch die
Kastenform werkzeugseitig recht aufwendig wird. Die Seitenteile bestehen selbst
aus Kunststoff und weisen zusätzliche Schnapphaken auf, die nicht besonders
zuverlässig sind. Beim Einbau oder beim Transport der Teile können die Haken
abbrechen oder zumindest beschädigt werden. Dem zweiten Dokument können
ähnliche Nachteile zugeordnet werden. Als Hauptnachteil beider Dokumente wäre
zu nennen, daß die Montage der Seitenteile des Kühlers nicht durch Einschieben
der Seitenteile in Richtung der Flachrohre des Kühlers bzw. senkrecht zur
Längsrichtung der Kunststoffkästen erfolgen kann, sondern ausschließlich durch
seitliches Heranführen, in Längsrichtung der Kunststoffkästen, wodurch die
Laschen der Seitenteile aufgebogen werden. Ferner lassen diese formschlüssigen
Verbindungen keine Längenausdehnung des Kühlnetzes bei dessen Erwärmung
zu. Dafür müssen in den Seitenteilen aus den bekannten Lösungen extra Vorkehrung
getroffen werden. Gewöhnlich werden Sicken oder dergleichen in die
Seitenteile eingeprägt. Jede Verformung am Seitenteil wirkt sich auf die
Werkzeugkosten aus. Es ist deshalb anzustreben die Längenausdehnung des
Kühlnetzes zu ermöglichen, ohne jedoch für diesen Zweck Sicken oder die Stabilität
herabsetzende Einschnitte im Seitenteil vornehmen zu müssen.The invention relates to a water / air cooler for internal combustion engines, in particular for commercial vehicles with the features of the preamble in claim 1.
The water / air cooler designed in this way is known from EP 504 034. In the known water / air cooler, all connections of the side parts to the plastic water tanks are made by means of thread-cutting screws. The screwing operations are time consuming and each screw represents an individual part that must be provided. Therefore there are solutions, such as those from EP 346 602 and EP 504 635, which do not require screw connections. For this purpose, positive connections are provided, which consist of pegs molded onto the plastic water tank, which snap into openings in the side parts. In the first-mentioned document, four pegs have been formed on each end of the box, making the box shape quite expensive on the tool side. The side parts themselves are made of plastic and have additional snap hooks that are not particularly reliable. When installing or transporting the parts, the hooks can break off or at least be damaged. Similar disadvantages can be assigned to the second document. The main disadvantage of both documents should be mentioned that the mounting of the side parts of the cooler can not be done by inserting the side parts in the direction of the flat tubes of the cooler or perpendicular to the longitudinal direction of the plastic boxes, but only by moving them sideways, in the longitudinal direction of the plastic boxes, which means that the tabs the side parts are bent open. Furthermore, these positive connections do not allow the cooling network to expand in length when it is heated. For this, extra precautions must be taken in the side panels from the known solutions. Ribs or the like are usually embossed into the side parts. Any deformation on the side part affects the tool costs. It is therefore desirable to enable the cooling network to expand in length, without having to make beads or incisions in the side part that reduce stability for this purpose.
Die Aufgabe der Erfindung besteht in einer einfachen Verbindung, die eine unter engen räumlichen Verhältnissen vereinfachte Montage der Seitenteile mit den Kunststoffwasserkästen zuläßt und die die Längenausdehnung des Kühlnetzes gestattet.The object of the invention is a simple connection, the one under narrow spatial conditions simplified assembly of the side parts with the Allows plastic water tanks and the length of the cooling network allowed.
Diese Aufgabe wird durch die kennzeichnenden Merkmale des Anspruchs 1
gelöst.
Wegen der Abkantung im Stegteil des Seitenteiles und der gleitenden Aufnahme
der Zapfen in den korrespondierende Öffnungen erlaubt die erfindungsgemäße
Lösung, daß sich das Kühlnetz in Längsrichtung der Flachrohre ausdehnen kann.
Die durch die Abkantung erreichte Elastizität in diesem Bereich gewährleistet
zusätzliche Sicherheit. Langlöcher in den Seitenteilen sind prinzipiell nicht mehr
notwendig. Sie können jedoch, gewissermaßen zusätzlich, vorgesehen werden.
Durch die Löcher werden gewindeschneidende Schrauben hindurchgesteckt, die
der Verbindung der Seitenteile mit den Kunststoffwasserkästen am gegenüberliegenden
Kasten dienen. Die dazu verwendeten Schrauben besitzen einen am
Schraubenkopf angeformten Bund, dessen Durchmesser geringfügig kleiner als
der kleine Durchmesser des Langloches bzw. als der Lochdurchmesser ist und
dessen Dicke der Dicke des Seitenteiles entspricht.This object is achieved by the characterizing features of claim 1.
Because of the bend in the web part of the side part and the sliding reception of the pins in the corresponding openings, the solution according to the invention allows the cooling network to expand in the longitudinal direction of the flat tubes. The elasticity achieved in this area by the fold ensures additional safety. In principle, elongated holes in the side panels are no longer necessary. However, they can be provided, to a certain extent, in addition. Threading screws are inserted through the holes, which are used to connect the side parts to the plastic water tanks on the opposite tank. The screws used for this purpose have a collar formed on the screw head, the diameter of which is slightly smaller than the small diameter of the elongated hole or the hole diameter and the thickness of which corresponds to the thickness of the side part.
Der Montageprozeß wurde dadurch vereinfacht, daß die Seitenteile sowohl in Längsrichtung der Kunststoffkästen als auch senkrecht dazu, also von oben, an den Kühler herangeführt werden können. Dies ist besonders bei beengten räumlichen Verhältnissen von Bedeutung. Dabei werden zunächst die Zapfen in die Öffnungen im Stegteil eingeführt, wobei gleichzeitig die Rastelemente an den Laschen der Seitenteile hinter Anschläge am Kunststoffkasten einrasten. Die Rastelement bewirken die provisorische Befestigung der Seitenteile in ihrer Sollposition. Anschließend kann die Schraubverbindung am gegenüberliegenden Kasten erfolgen. Die Anordnung der Zapfen an der Querwand des Wasserkastens, die in Richtung der Flachrohre wegweisen, hat darüber hinaus den Vorteil, daß die Ausformbarkeit des Wasserkastens aus dem Spritzgußwerkzeug vereinfacht worden ist und daß die Werkzeugkosten trotz der Zapfen nicht wesentlich erhöht werden.The assembly process was simplified in that the side parts in both Longitudinal direction of the plastic boxes as well as perpendicular to it, i.e. from above the cooler can be brought up. This is especially true in tight spaces Conditions of importance. The pins are first inserted into the openings inserted in the web part, with the locking elements at the same time Snap in the tabs on the side parts behind the stops on the plastic box. The Locking element effect the provisional fastening of the side parts in their target position. Then the screw connection on the opposite Box done. The arrangement of the pegs on the transverse wall of the water tank, which in the direction the flat tubes point away has the additional advantage that the formability the water box has been simplified from the injection mold and that the tool costs are not significantly increased despite the tenons.
Die Erfindung wird nachfolgend in Ausführungsbeispielen anhand der beiliegenden
Zeichnungen erläutert.
Das
The
Beide Seitenteile 6 und 7 dienen der Abstützung des Kühlers im Fahrzeug, wozu
entsprechende Halterungen 13 vorgesehen sind. Aus diesem Grund ist deren
ausreichende Stabilität und auch eine sichere Verbindung mit den Kunststoffwasserkästen
1 und 2 wesentlich. Hierzu leisten die auch von den Stirnseiten
eingeführten Schrauben 9 ihren Beitrag.
Die in Fig.1 eingekreiste obere Verbindung 14 ist in den Fig. 2 bis 7 in mehreren
Beispielen näher gezeigt worden. Es versteht sich, daß es vollkommen egal ist, ob
die Verbindung 14 oben oder unten vorgesehen ist. In den Fig. 2 und 3 sind die
Zapfen 15 unmittelbar an der Querwand 16 des Kunststoffkastens 1 angeformt
worden. Sie erstrecken sich in Richtung der Flachrohre, also im Bild vertikal nach
oben. Das Stegteil 17 weist eine Abkantung 18 auf und drei Öffnungen 19. Die
Abkantung besitzt hier einen Winkel 21 von 90°, weil die Querwand 16 parallel zu
den Rohrböden 24 angeordnet ist. Die Größe des Winkels 21 wird also durch die
Geometrie des Wasserkastens 1 bestimmt und kann ohne weiteres abweichend
von den gezeigten Ausführungsbeispielen sein. Die Öffnungen 19 haben einen
Kragen 20, der in den Fig. 2 und 3 nach oben gerichtet ist. Es versteht sich, daß
sowohl an den Zapfen 15 als auch an den Öffnungen 19 abgerundete Kanten
vorgesehen werden, um das Einführen der Zapfen 15 in diese Öffnungen 19 zu
erleichtern.
Die Fig. 3 zeigt, daß die Zapfen 15 und die korrespondierenden Öffnungen 19
zueinander so angeordnet sind, daß sie ein gleichseitiges Dreieck einschließen.
Von einiger Bedeutung ist nun die Form der einzelnen Öffnungen 19, die zwar bei
allen Öffnungen 19 gleich ist, jedoch sind zwei Öffnungen 19 mit ihrer Längsachse
in Richtung der Längsachse des Wasserkastens 1 angeordnet und die dritte Öffnung
mit ihrer Längsachse quer dazu. Damit wird die Fixierung in Längs-und
Querrichtung erreicht. An den Laschen 10 befindet sich je eine Anformung in Form eines Rastelementes 22,
das am zur Kühlermitte weisenden Ende der Laschen 10 angeordnet worden ist.
Die Rastelemente 22 sind halbrund im Querschnitt, so daß sich beim Aufschieben
der Seitenteile 6 und 7 die Laschen 10 unter Ausnutzung der Elastizität etwas
aufbiegen und die Seitenteile 6 und 7 bis in ihre Sollposition gebracht werden
können, wo die Rastelemente 22 hinter am Wasserkasten 1 angeformte Anschläge
23 greifen.
Das abgekantete Stegteil 17 befindet sich nur an einem Ende der Seitenteile 6
und 7, nicht am gegenüberliegenden anderen Ende der Seitenteile 6 und 7. Both

Deshalb können die Seitenteile 6 und 7 auch von oben montiert werden, indem
das mit den Langlöchern 11 versehene untere Ende der Seitenteile 6 und 7
zunächst den oberen Wasserkasten 1 umgreift und anschließend senkrecht nach
unten in die Sollposition bewegt werden kann.Therefore, the
In den Fig. 4, 4a und 5 ist ein Ausführungsbeispiel gezeigt, bei dem die Zapfen 15
Einzelteile sind, die aus Metall sein könnten. Auch diese Zapfen 15 haben einen
zylinderförmigen Kopf 24, an dem sich eine gewindeschneidende Schraube 25
anschließt. In der Querwand 16 des Kunststoffwasserkastens 1 befinden sich
glattwandige Bohrungen bzw. Sacklocher 27, in die die Zapfen 15 mit ihren
Schrauben 25 eingedreht werden können.(Fig. 4a) Bei dem Ausführungsbeispiel
gemäß Fig. 4 ist ein glattwandiger Stift 28 am Zapfen 15 angeformt, der einfach in
die glattwandige Bohrung 27 eingeführt ist. Da hier lediglich Kräfte quer zur
Längsachse der Zapfen 15 aufgenommen werden müssen, ist auch eine solche
Ausführung möglich und noch kostengünstiger.
Die Fig. 6 und 7 unterscheiden sich von den Fig. 2 und 3 dadurch, daß eine andere
Form der Zapfen 15 gewählt worden ist. Sinngemäß sind die Öffnungen 19
an die Form der Zapfen 15 angepaßt worden. Der Kragen 20 ist nach innen
gerichtet.
Die Fig. 8 zeigt die im Ausführungsbeispiel untere Befestigung etwas näher. Gewindeschneidende
Schrauben 9 sind in glattwandige Bohrungen 12 eingeschraubt.
Der Bereich der Schrauben 9 wurde herausgebrochen gezeichnet. Die
glattwandigen Bohrungen 12 sind in Anformungen 26 am Kunststoffkasten ausgebildet.
Solche Schrauben 9 sind sowohl im Stegteil 17, also der Stirnseite des
Wasserkühlers, als in den Laschen 10, also von den Frontseiten des
Wasserkühlers vorgesehen worden. 4, 4a and 5, an embodiment is shown in which the
6 and 7 differ from FIGS. 2 and 3 in that a different shape of the
8 shows the lower fastening in the exemplary embodiment somewhat closer. Tapping
