Diesen Zweck erreicht die Erfindung durch die Merkmale gemäß dem Kennzeichen des Patentanspruches 1. Damit ist auch eine allgemeine Anwendung bei allen flüssigkeitsgekühlten Brennkraftmaschinen möglich. Die Patentansprüche 2 bis 5 enthalten Merkmale, die die Anwendung der Erfindung bei üblichen Kühlern mit Wärmetausch zwischen der Umgebungsluft und der Maschinen-Kühlflüssigkeit besonders vorteilhaft ermöglichen und den Bauaufwand einer derartigen Kühlvorrichtung besonders gering halten, da dabei der Rücklauf-Wasserkasten des Kühlers mit dem Gehäuse des Thermostats, abgesehen von dessen Deckel, einteilig und als einfach ausformbares Kunststoff-Spritzteil herstellbar sind.The object of the invention is to enable the use of such a cooling device with a thermostat integrated in the heat exchanger also in all other conventional liquid-cooled internal combustion engines, such as in particular in internal combustion engines for driving motor vehicles. The invention achieves this purpose by the features according to the characterizing part of patent claim 1. This also enables general use in all liquid-cooled internal combustion engines. The claims 2 to 5 contain features that enable the use of the invention in conventional coolers with heat exchange between the ambient air and the machine coolant particularly advantageous and the construction cost keep such a cooling device particularly low, since the return water tank of the cooler with the housing of the thermostat, apart from its cover, can be produced in one piece and as an easily molded plastic injection-molded part.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Es zeigen:

  • Fig. 1 die Prinzipdarstellung eines Querstromkühlers für Brennkraftmaschinen mit einem Thermostat am Rücklauf-Wasserkasten und
  • Fig. 2 den dem Rücklauf-Wasserkasten des Querstromkühlers einteilig angeformten Thermostat im Längsschnitt nach der Linie II-II in Fig. 1.
In the drawing, an embodiment of the invention is shown. Show it:
  • Fig. 1 shows the schematic diagram of a cross-flow cooler for internal combustion engines with a thermostat on the return water tank and

Ein als Kühler für Brennkraftmaschinen von Kraftfahrzeugen, wie insbesondere Personenkraftwagen und Motorräder bestimmter Wärmetauscher 1 für Luft und Kühlflüssigkeit ist als Querstromkühler ausgebildet. Er weist beiderseits seines Kühlerfeldes 2 je einen Vorlauf-Wasserkasten 3 und Rücklauf-Wasserkasten 4 auf.A heat exchanger 1 for air and coolant, which is designed as a cooler for internal combustion engines of motor vehicles, such as, in particular, automobiles and motorcycles, is designed as a cross-flow cooler. It has a flow water box 3 and a return water box 4 on both sides of its cooler field 2.

In den Vorlauf-Wasserkasten 3 mündet ein Eintrittsstutzen 5 einer nicht dargestellten Vorlaufleitung, die gemäß Pfeil 6 die Kühlflüssigkeit von der Brennkraftmaschine in den Wärmetauscher 1 leitet. Das Kühlerfeld 2 wird gemäß den Pfeilen 7 horizontal von der Kühlflüssigkeit durchströmt und dabei die abzuführende Wärme aus der Kühlflüssigkeit an die das Kühlerfeld gleichfalls - senkrecht zur Zeichnungsebene - durchströmende Kühlluft übertragen.An inlet connection 5 of a flow line, not shown, which leads the coolant from the internal combustion engine into the heat exchanger 1 according to arrow 6, opens into the flow water box 3. The cooler field 2 is flowed through horizontally by the coolant according to the arrows 7 and the heat to be dissipated is thereby transferred from the coolant to the cool air also flowing through the cooler field - perpendicular to the plane of the drawing.

Der Rücklauf-Wasserkasten 4 weist an seiner Oberseite einen Einfüllstutzen 8 auf, der an seiner Einfüllöffnung mit einem übliche Überdruck- und Unterdruck-Ventileenthaltenden Verschlußdeckel 9 ausgestattet ist. An seiner Unterseite ist dem Rücklauf-Wasserkasten 4 ein im wesentlichen mehrfach-zylindrisch im Innenquerschnitt abgestuftes Gehäuse 10 eines Thermostats 10',ein Kurzschluß-Anschlußstutzen 11 und ein Austrittsstutzen 12 einteilig angeformt. Die Achse der zueinander konzentrischen Zylinder-Abschnitte des Gehäuses 10 und des Kurzschluß-Anschlußstutzens 11 ist in Richtung der aus der Zeichnungsebene gerichteten Luftströmung angeordnet. Der Austrittsstutzen 12 erstreckt sich radial dazu nach unten, oder ggf. zur Seite oder ggf. auch schräg nach seitlich-unten, je nach Weiterführung einer nicht gezeigten Rücklaufleitung zur Brennkraftmaschine.The return water tank 4 has on its top a filler neck 8, which is equipped at its filler opening with a conventional cover 9 containing pressure and vacuum valves. On the underside of the return water tank 4, a housing 10 of a thermostat 10 ', a short-circuit connecting piece 11 and an outlet piece 12, is formed in one piece in a substantially multi-cylindrical internal cross section. The axis of the concentric cylinder sections of the housing 10 and the short-circuit connecting piece 11 is arranged in the direction of the air flow directed from the plane of the drawing. The outlet nozzle 12 extends radially downward, or possibly to the side or possibly also obliquely to the side and down, depending on the continuation of a return line, not shown, to the internal combustion engine.

Das Gehäuse 10 des Thermostats 10' enthält einen üblichen Thermostateinsatz 13 mit einem Befestigungsflansch 14 mit Kühler-Ventilöffnung, einem Dehnstoffelement 15, einem Kühler-Ventilteller 16 und einem Kurzschluß-Ventilteller 17. Der Befestigungsflansch 14 wird von einem Verschlußdeckel 18 dichtend gegen eine Abstufung des Innenquerschnitts des Gehäuses 10 gespannt. Der Verschlußdeckel 18 weist hierfür eine nicht dargestellte Flanschverbindung mit Dichtring 19 am Endbereich 20 des Gehäuses 10 sowie kronenförmig angeordnete Axial-Ansätze 21 auf, deren Stirnseiten am Befestigungsflansch 14 anliegen und deren fensterartige Aussparungen 22 Eintrittsöffnungen für die Kühlflüssigkeit in eine'im Verschlußdeckel 18 angeordnete Zulaufkammer 23 des Gehäuses 10 bilden. Den Aussparungen 22 sind fensterartige Öffnungen 24 in der Trennwand des Gehäuses 10 zum Inneren des Rücklauf-Wasserkastens 4 zugeordnet.Eine enge Entlüftungsöffnung 25 verbindet den als Mischkammer 26 wirkenden Innenquerschnitt des Gehäuses 10 an einer in Betriebslage obenliegenden Stelle ebenfalls mit dem Inneren des Rücklauf-Wasserkastens 4. Die Abstufung des Innenquerschnitts des Gehäuses 10 von der Mischkammer 26 zum Kurzschluß-Anschlußstutzen 11 ist als Ventilsitz 27 für die zugeordnete Eintrittsöffnung 28 zur Mischkammer 26 ausgebildet.The housing 10 of the thermostat 10 'contains a conventional thermostat insert 13 with a mounting flange 14 with a radiator valve opening, an expansion element 15, a radiator valve plate 16 and a short-circuit valve plate 17. The mounting flange 14 is sealed by a cover 18 against a gradation of Clamped internal cross section of the housing 10. For this purpose, the closure cover 18 has a flange connection (not shown) with a sealing ring 19 at the end region 20 of the housing 10 and axial projections 21 arranged in a crown, the end faces of which abut the fastening flange 14 and whose window-like recesses 22 have inlet openings for the cooling liquid in an inlet chamber arranged in the closure cover 18 23 of the housing 10 form. The cutouts 22 are assigned window-like openings 24 in the partition of the housing 10 to the interior of the return water tank 4. A narrow ventilation opening 25 connects the inner cross section of the housing 10, which acts as a mixing chamber 26 at an upper position in the operating position also with the inside of the return water tank 4. The gradation of the inner cross section of the housing 10 from the mixing chamber 26 to the short-circuit connecting piece 11 is designed as a valve seat 27 for the associated inlet opening 28 to the mixing chamber 26.

Der Rücklauf-Wasserkasten 4 ist mit dem Gehäuse 10 des Thermostats 10' einteilig aus Metall oder insbesondere aus Kunststoff in Druckguß bzw. Spritzguß ausgeformt, so daß sowohl die Herstellungskosten als auch das Gewicht der erfindungsgemäßen Kühlvorrichtung niedrig sind. Dies wird auch dadurch begünstigt, daß das Gehäuse 10 des Thermostats 10' im Gegensatz zu seiner üblichen Anordnung am Gehäuse von Brennkraftmaschinen nicht dessen Höchsttemperatur, sondern äußerstens der Höchsttemperatur der Kühlflüssigkeit ausgesetzt ist, die wesentlich niedriger liegt und die Anwendung preisgünstiger Kunststoffe ermöglicht.The return water tank 4 is formed with the housing 10 of the thermostat 10 'in one piece from metal or in particular from plastic in die casting or injection molding, so that both the manufacturing costs and the weight of the cooling device according to the invention are low. This is also favored by the fact that the housing 10 of the thermostat 10 ', in contrast to its usual arrangement on the housing of internal combustion engines, is not exposed to its maximum temperature, but rather to the maximum temperature of the coolant, which is much lower and enables the use of inexpensive plastics.
