Abstract

2.1 Known cooling systems have separate radiators (3), compensating tanks (2) and fan shrouds (1). These parts must then all be fitted separately and, since they are mostly fitted at different points in the vehicle, hose lines must be led from the various attachment points to the internal-combustion engine. 2.2 According to the invention, the compensating tank (2) and the fan shroud (1) are produced as one piece and are constructed as a support for the radiator (3). In consequence, only one part has to be attached to the vehicle or to the internal-combustion engine and only one pipe system provided for the connection of the cooling system to the internal-combustion engine. <IMAGE>

Description

Die Erfindung betrifft ein Kühlsystem für Brennkraftma­schinen gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a cooling system for internal combustion engines according to the preamble of patent claim 1.

Aus dem Fahrzeugbau sind Kühlsysteme für Brennkraftma­schinen bekannt, die aus Kühler, Gebläsemantel und Aus­gleichsbehälter bestehen. Dabei sind die zuvor genannten Teile alle separat voneinander gefertigt und angeordnet. Dies bedeutet, daß die Teile einzeln befestigt werden müssen und von der Brennkraftmaschine zu den verschiedenen Befestigungsstellen Schlauchverbindungen geführt werden. Neben einem hohen Produktionsaufwand ergeben sich folglich auch bei einer Wartung bzw. einem Austausch der Teile hohe Kosten.Cooling systems for internal combustion engines are known from vehicle construction, which consist of a cooler, blower jacket and expansion tank. The aforementioned parts are all manufactured and arranged separately from one another. This means that the parts must be attached individually and hose connections are led from the internal combustion engine to the various attachment points. In addition to high production costs, maintenance and replacement of the parts also result in high costs.

Der Erfindung liegt die Aufgabe zugrunde, ein Kühlsystem bereitzustellen, das die zuvor genannten Nachteile vermei­det, kostengünstig herstellbar und wartungsfreundlich sein soll.The invention has for its object to provide a cooling system that avoids the disadvantages mentioned above, should be inexpensive to manufacture and easy to maintain.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Ausgleichsbehälter und der Gebläsemantel einstückig gefer­tigt sind und als Träger für den Kühler ausgebildet sind.This object is achieved in that the expansion tank and the blower jacket are made in one piece and are designed as a carrier for the cooler.

Claims (4)

1. Kühlsystem für Brennkraftmaschinen, das zumindest einen Kühler (3), einen Gebläsemantel (1) und einen Aus­gleichsbehälter (2) aufweist,
dadurch gekennzeichnet, daß der Ausgleichsbehälter (2) und der Gebläsemantel (1) einstückig gefertigt sind und als Träger für den Kühler (3) ausgebildet sind.1. Cooling system for internal combustion engines, which has at least one cooler (3), a blower jacket (1) and an expansion tank (2),
characterized in that the expansion tank (2) and the blower jacket (1) are made in one piece and are designed as supports for the cooler (3). 2. Kühlsystem nach Anspruch 1,
dadurch gekennzeichnet, daß an geodätisch niedrigster Stelle des Trägers eine in die Umgebung mündende und mit einer Verschlußschraube (11) verschließbare Öffnung (9) angeordnet ist, die mit dem Innenraum des Ausgleichsbehäl­ters (2) und dem Innenraum des Kühlers (3) verbunden ist.2. Cooling system according to claim 1,
characterized in that an opening (9) opening into the surroundings and closable with a screw plug (11) is arranged at the geodetically lowest point of the carrier and is connected to the interior of the expansion tank (2) and the interior of the cooler (3). 3. Kühlsystem nach Anspruch 2,
dadurch gekennzeichnet, daß die Verschlußschraube (11) in einer eingeschraubten Stellung den Innenraum des Aus­gleichsbehälters (2) von dem Innenraum des Kühlers (3) und von der Umgebung absperrt.3. Cooling system according to claim 2,
characterized in that the screw plug (11) shuts off the interior of the expansion tank (2) from the interior of the cooler (3) and from the surroundings in a screwed-in position. 4. Kühlsystem nach Anspruch 2 oder 3, dadurch gekennzeichnet, daß die Verschlußschraube (11) in einer Entlüftungsstellung eine Verbindung zwischen dem Innenraum des Ausgleichsbehälters (2) und dem Innenraum des Kühlers (3) freigibt und den Innenraum des Ausgleichs­behälters (2) und den Innenraum des Kühlers (3) gegen die Umgebung absperrt.4. Cooling system according to claim 2 or 3, characterized in that the screw plug (11) in a ventilation position releases a connection between the interior of the expansion tank (2) and the interior of the cooler (3) and shuts off the interior of the expansion tank (2) and the interior of the cooler (3) from the environment.
