This enables a compact design and simplifies and speeds up assembly. The valve regulates the coolant throughput via the heat exchanger depending on the coolant temperature.
Vorzugsweise weist das Kühlmodul einen Sensor zum Regeln der Kühlmit- teltemperatur auf, wobei der Sensor in das Kühlmodul integriert ist und die Temperatur des Kühlmittelkreislaufs überwacht. Hierbei kann der Sensor an einem Ventil angebracht oder in dasselbe integriert sein.

The control module is preferably via an interface with an external one Sieuermodul, ie connected to a control module outside the module frame.
Vorzugsweise ist der Anschluss der Kühlmittelpumpe etwa in der Mitte auf einer Seite des Modulrahmens angeordnet. Dies ermöglicht eine optimale Kraftübertragung und Kraftweiterleitung im Modulrahmen. Die Anordnung der Kühlmittelpumpe kann auch außermittig, ober- oder unterhalb des Kühlmoduls sein. Die Wahl der Anordnung der Kühlmittelpumpe hängt insbesondere von der Bauraumsituation ab.The connection of the coolant pump is preferably arranged approximately in the middle on one side of the module frame. This enables optimal power transmission and power transmission in the module frame. The arrangement of the coolant pump can also be off-center, above or below the cooling module. The choice of arrangement of the coolant pump depends in particular on the installation space situation.
Vorzugsweise ist die Kühlmittelpumpe und/oder das Ventil parallel zu dem Bereich des Modulrahmens ausgerichtet, in dem sie bzw. es angebracht ist. Auf diese Weise ist eine optimale Befestigung und Kraftübertragung auf den Modulrahmen möglich.The coolant pump and / or the valve is preferably aligned parallel to the region of the module frame in which it is attached.

Vorzugsweise ist die Kühlmittelpumpe derart am Modulrahmen angeordnet, dass die Kühlluft die Elektronik der Kühlmittelpumpe umströmen und somit kühlen kann.

Im folgenden wird die Erfindung anhand zweier Ausführungsbeispiele unterThe invention is described below using two exemplary embodiments

Ein Verbrennungs-Motor 1 eines Kraftfahrzeugs weist ein Kühlmodul 2 auf, welches im wesentlichen in und/oder an einem Modulrahmen 3 angeordnet ist. Teil des Kühlmoduls 2 ist mindestens ein im Modulrahmen 3 vorgesehener und daran befestigter Wärmetauscher 4 (Kühler) mit zwei Sammelbehältern 5, wovon der eine der Sammelbehälter 5 als Sammlervorlauf und der andere als Sammlerrücklauf dient.An internal combustion engine 1 of a motor vehicle has a cooling module 2, which is arranged essentially in and / or on a module frame 3. Part of the cooling module 2 is at least one heat exchanger 4 (cooler), which is provided in the module frame 3 and fastened thereon, with two collecting containers 5, one of which serves as a collector flow and the other as a collector return.
Der Wärmetauscher 4 samt Sammelbehältern 5 ist Teil eines Motor- Kühlmittelkreislaufs 6, durch welchen ein Kühlmittel, angetrieben durch eine elektrische Kühlmittelpumpe 8 strömt. Im Kühlmittelkreislauf 6 ist, dem Wär- metauscher 4 mit Sammelbehälter 5 nachgeordnet, ein Ventil 9 vorgesehen, weiches über einen Anschluss 10 mit einem der Sammelbehälter 5 des Wärmetauschers-4 verbunden ist. Dabei ist gemäß dem vorliegenden Ausführungsbeispiel beim Ventil 9 ein zweiter Anschluss 10' für einen Bypass 18 vorgesehen, mittels dem das Kühlmittel am Wärmetauscher 4 vorbei und direkt der Kühlmittelpumpe 8 zugeführt werden kann. Der Bypass 18 kann auch in das Kühlmodul oder in den Modulrahmen integriert sein. Durch diese Maßnahme kann die Zahl der Anschlüsse an dem Kühlmodul reduziert werden.The heat exchanger 4 together with the collecting containers 5 is part of an engine coolant circuit 6, through which a coolant, driven by an electric coolant pump 8, flows. A valve 9 is provided in the coolant circuit 6, downstream of the heat exchanger 4 with the collecting container 5. which is connected via a connection 10 to one of the collecting containers 5 of the heat exchanger-4. According to the present exemplary embodiment, a second connection 10 ′ for a bypass 18 is provided for the valve 9, by means of which the coolant can pass the heat exchanger 4 and be fed directly to the coolant pump 8. The bypass 18 can also be integrated in the cooling module or in the module frame. This measure allows the number of connections on the cooling module to be reduced.
Das Ventil 9 kann sowohl dem Wärmetauscher 4 nachgeordnet, also an seiner Austrittsseite angebracht sein, wie in den Figuren dargestellt, als auch gemäß einer alternativen Ausführungsform an seiner Eintrittsseite. Entsprechendes gilt auch für die Kühlmittelpumpe 8. Diese kann nach dem Austritt des Wärmetauschers 4 liegen (Saugseite - vgl. Fig. 3 und 4), oder aber ge- maß einer alternativen Anordnung vor dem Eintritt des Wärmetauschers 4 (Druckseite) angeordnet sein.The valve 9 can be arranged downstream of the heat exchanger 4, that is to say attached to its outlet side, as shown in the figures, or, according to an alternative embodiment, on its inlet side. The same also applies to the coolant pump 8. This can be located after the outlet of the heat exchanger 4 (suction side - see FIGS. 3 and 4), or it can be arranged according to an alternative arrangement before the inlet of the heat exchanger 4 (pressure side).
Gemäß dem ersten Ausführungsbeispiel ist der Anschluss 10' in axialer Richtung bezüglich der Kühlmittelpumpe 8 angeordnet. Das Ventil 9 wird in Abhängigkeit der Messergebnisse eines Sensors 11 mit Hilfe eines Steuermoduls 12 geregelt, wobei das Steuermodul 12 seinerseits mit einem externen Steuermodul 14 verbunden ist. Das Steuermodul 12 regelt ferner die Kühlmittelpumpe 8 sowie ein Gebläse 16 mit einem Lüfterrad, welches benachbart zum Wärmetauscher 4 angeordnet ist. Das Gebläse 16 ist an Ge- bläsezargen 17 angebracht, welche innerhalb vom Modulrahmen 3 angeordnet sind.According to the first exemplary embodiment, the connection 10 ′ is arranged in the axial direction with respect to the coolant pump 8. The valve 9 is regulated as a function of the measurement results of a sensor 11 with the aid of a control module 12, the control module 12 in turn being connected to an external control module 14. The control module 12 also regulates the coolant pump 8 and a blower 16 with a fan wheel, which is arranged adjacent to the heat exchanger 4. The blower 16 is attached to blower frames 17 which are arranged inside the module frame 3.
Gemäß einer Variante kann das Ventil 9 auch ein nur von der Kühlmitteltemperatur und nicht vom Steuermodul 12 abhängiger Regler sein, beispielswei- se ein Dehnstoffthermostat. Das Steuermodul 12 regelt dann nur die Kühlmittelpumpe 8 und das Gebläse 16.According to a variant, the valve 9 can also be a controller that is dependent only on the coolant temperature and not on the control module 12, for example an expansion thermostat. The control module 12 then regulates only the coolant pump 8 and the blower 16.
Gemäß dem ersten Ausfüh'rungsbeispiel ist die Kühlmittelpumpe 8 etwa mittig direkt am Modulrahmen 3 anliegend auf einer Seite desselben ange- bracht, wobei der Modulrahmen 3 das tragende Bauteil des Kühlmoduls 2 ist und die Kraftübertragung direkt über den Modulrahmen 3 auf die (nicht datgestellte) Fahrzeugkarosser-ie-erfolgt. Jedoch kann die Anordnung der Kühlmittelpumpe auch außermittig sowie ober- oder unterhalb des Kühlmoduls erfolgen.According to the first exporting 'approximately, for example, the coolant pump is about 8 centrally placed directly on the module frame 3 adjacent the same on one side reasonable, wherein the module frame 3 is the supporting component of the cooling module 2 and the power transmission takes place directly via the module frame 3 to the vehicle body (not shown). However, the coolant pump can also be arranged off-center and above or below the cooling module.
Bei der Montage erfolgt zuerst eine Vormontage, bei der mit dem Modulrahmen 3 verbundene Bauteile des Kühlmoduls 2 an dem Modulrahmen 3 befestigt werden. Erst im Rahmen der eigentlichen Montage wird das vormontierte Kühlmodul 2 in die Fahrzeugkarosserie eingesetzt und darin befestigt.During assembly, there is first a pre-assembly in which components of the cooling module 2 connected to the module frame 3 are fastened to the module frame 3. The preassembled cooling module 2 is only inserted into the vehicle body and fastened in the course of the actual assembly.
Gemäß dem in den Figuren 2 und 4 dargestellten zweiten Ausführungsbeispiel, bei dem die gleichen Bezugszeichen verwendet werden, ist der Bypass 18 integriert ausgebildet. Ansonsten stimmt das zweite Ausführungsbeispiel mit dem zuvor beschriebenen ersten Ausführungsbeispiel überein. According to the second exemplary embodiment shown in FIGS. 2 and 4, in which the same reference numerals are used, the bypass 18 is designed to be integrated. Otherwise, the second embodiment corresponds to the previously described first embodiment.
