Description

Aus zwei durch Windflügel belüftete und durch wärmeempfindliche Glieder nacheinander einschaltbaren Blöcken bestehender Kühler für Brennkraftmaschinen, insbesondere von Kraftfahrzeugen . Es ist bekannt, die Wirksamkeit der Kühlanlage dadurch den jeweils vorliegenden Betriebsbedingungen einer Brennkraftmaschine weitgehend anpaßbar zu machen, daß der Kühler in mehrere Blöcke unterteilt wird, die durch bei verschiedenen Temperaturen ansprechende wärmeempfindliche Glieder .nacheinander ein- oder abgeschaltet werden.Made of two sections ventilated by wind blades and sensitive to heat successively switchable blocks of existing coolers for internal combustion engines, in particular of motor vehicles. It is known the effectiveness of the cooling system thereby largely the existing operating conditions of an internal combustion engine to make adaptable that the cooler is divided into several blocks, which by heat-sensitive members responding at different temperatures can be switched on or off.

Ferner ist bereits vorgeschlagen worden, die Wirksamkeit der Kühlanlage durch Büein flussen ,der Windfiü-eldrehzalil regelbar zu gestalten. Das kannbeispielsweise .durch, eine im Durchmesser vertinclerliclie Riemenscbeibe mit gegeneinander axial verschiebbaren Hälften geschelucii. Die vorliegende Erf ndung hat nun eine Vergrößerung .des mit den bekannten Linrichtungen erreichbaren Regelbereicli-es von Kühlanlagen zum Ziele und schafft a@nc Anlage, die sich selbsttätig und rasch auch schnell wechselnden Betriel)sbedin,-tin-en, wc sie vor allen Dingen bei Brcnakraftmaschiiien von Kraftfahrzeugen auftreten, anlial;t und sich ständig auf die günstigste Betriebstemperatur einstellt. Das wird durch Reglung sowohl der im Umlauf befindlichen Külilmittelmcnge als auch der Förderleistung des Wind(lüc#els auf die Weise erreicht, dal3 bei der aus zwei durch %värmecmpfinclliclic Gllcclcr nacheinander einschaltbaren Blöcken bestehenden Kühlanlage das wärmeempfindliche Glied für den zweiten Block bleichzeitig den Wiaidflügel in an sich bekannter Weise über ein Gestänge mit im Durchmesser veränderlichen Riemenscheiben in der Drehzahl steuert.Furthermore, it has already been suggested the effectiveness of the cooling system to make the wind flow rate controllable through office influences. For example .by, a vertinclerliclie in diameter belt pulley with against each other axially sliding halves geschelucii. The present invention now has an enlargement The control areas of cooling systems that can be achieved with the known lines to the goal and creates a @ nc system that changes automatically and quickly They concern, above all, fuel engines of motor vehicles occur, anlial; t and constantly adjusts to the most favorable operating temperature. This is done by regulating both the amount of coolant in circulation and the the delivery rate of the wind (lüc # els achieved in the way that in the case of two with% värmecmpfinclliclic Gllcclcr blocks that can be switched on one after the other Cooling system the heat sensitive member for the second block at the same time the wiaid wing in in a manner known per se via a linkage with pulleys of variable diameter controls in speed.

In der Zeichnung ist ein Ausführungsbeispiel des- Erfindungsgegenstandes dargestellt. Fig. i stellt eine Ansicht des Kühlerblockes in Fahrtrichtung, Fig. 2 eine Seitenansicht der gesamten Kühlanlage dar.In the drawing is an embodiment of the subject of the invention shown. Fig. I shows a view of the radiator block in the direction of travel, Fig. 2 shows a side view of the entire cooling system.

Der Kühler i ist durch eine Zwischienwand 2 in zwei Blöcke 3 und q. geteilt, die "über den unteren Wasserkasten 5 miteinander in Verbindung stehen. In den oberen Wasserkästen, ist bei jedem der beiden Blöcke 3 urid q. ein wärmeempfindliches Glied 6 und 7 eingebaut, die auf verschiedene Temperaturen, beispielsweise 70 und 9o° C, ansprechen. und den Kühlmitteldurchlauf durch den Block absperren oder freigeben. Eine Stange 8 des wärmeempfindlichen Gliedes 7 bewirkt bei der Bewegung desselben eine Drehung der senkrechten Welle 9, die durch eine Gabel i o den axial verschiebbaren Teil der Riemenscheibe i i am Windflügel 12 in dem Sinn verstellt, daß die beiden Riemenscheibenhälften bei geöffnetem Steuerglied der Regeldose 7 au' einandergezogert sind und damit der Riemen 13 auf dem Grund läuft, bei geschlossenem Steuerglied der Regeldose 7 dagegen zusammengedrückt sind und damit der Riemen 13 auf dem Atißendurclimesser aufliegt. Die treibende Riemenscheibe 14 auf dem vorderen Ende der Kurbehvelle kann ebenfalls zwei gegeneinander verschiebbare Hälften aufweisen, - die beispielsweise durch eine Feder 15 zusammengedrückt «-erden, so daß auf diese Weise der Riemen 13 stets gespannt bleibt.The cooler i is divided into two blocks 3 and q by an intermediate wall 2. divided, which are "connected to each other via the lower water tank 5. In the upper water tank, a heat-sensitive element 6 and 7 is installed in each of the two blocks 3 and 7, which respond to different temperatures, for example 70 and 90 ° C . and block or release the coolant flow through the block. A rod 8 of the heat-sensitive element 7 causes a rotation of the vertical shaft 9 during the movement of the same. that the two halves of the pulley are pulled apart when the control member of the control box 7 is open and so the belt 13 runs on the ground, but when the control member of the control box 7 is closed, they are pressed together and thus the belt 13 rests on the Atissen diameter knife. The driving belt pulley 14 on the front The end of the crank shaft can also have two mutually displaceable halves n, - which, for example, are compressed by a spring 15 - earth, so that in this way the belt 13 always remains tensioned.

'Die Wirkungsweise der neuen Kühlanlage ist folgende: Benn Anlassen der Maschine sind zunächst die Steuerglieder beider 6 und 7 geschlossen und damit der Kühlmittelumlauf unterbunden. Erwärmt sich die Maschine, so öffnet beim Erreichen einer Betriebstemperatur von etwa 70°C die Regeldose 6 ihr Steuerglied und schaltet damit den einen Block 3 des Kühlers i ein. Dieser KüliIerblock 3 genügt für geringe Belastungen, z. B. Stadtbetrieb, und es braucht in diesem Falle nur die Hälfte der gesamten Kühli<asserinenge erwärmt zu werden. Da außerdem die Riemenscheibe i i bei, Schließstellung des Steuergliedes der Regeldose 7 so gestellt ist, daß der Windflügel 12 langsam läuft, wird dieAnwärmung der verhältnismäßig kleinen Wassermenge noch beschleunigt, d. h. die Maschine erreicht sehr schnell eine günstige Betriebstemperatur und bleibt auch. auf dieser, da die Kühlwirkung des einen Blockes ; des Kühlers i eben gerade ausreicht, um die Wärmeabfuhr bei unterbrochenen Betrieb zu ermöglichen. Wird die Maschine stärker belastet, so steigt damit die Temperatur des Kühlwassers, und es öffnet sich auch das Steuerglied der Regeldose 7. Dabei wird der Windflügel 12 in schnellere Umdrehungen versetzt, weil die Riemenscheibe i i über das Gestänge 8, 9, io auseinandergezogen wird. Damit ist die Kühlung im Kühlmittelkreislauf geschaffen, mit der das Fahrzeug die hohe Belastung bewältigen kann.'The mode of operation of the new cooling system is as follows: Benn starting of the machine, the control members of both 6 and 7 are initially closed and thus the coolant circulation is stopped. If the machine warms up, it opens when it is reached an operating temperature of about 70 ° C, the control box 6 its control element and switches so that one block 3 of the cooler i a. This killer block 3 is sufficient for small Loads, e.g. B. City operation, and in this case it only takes half of the to be warmed up tightly throughout the entire cooling tank. In addition, since the pulley i i at, the closed position of the control member of the control box 7 is set so that the Wind blade 12 is running slowly, the heating of the relatively small amount of water still accelerated, d. H. the machine reaches a favorable operating temperature very quickly and stays. on this, as the cooling effect of one block; of the cooler i is just enough to allow heat to be dissipated during interrupted operation. If the machine is more heavily loaded, the temperature of the cooling water rises, and the control element of the control box 7 also opens. The wind vane is thereby activated 12 set in faster revolutions because the pulley i i over the linkage 8, 9, io is pulled apart. This creates the cooling in the coolant circuit, with which the vehicle can cope with the high load.

Die Erfindung ist nicht auf das Ausführungsbeispiel beschränkt. So können statt eines geteilten Kühlers zwei Einzelkühler, gegebenenfalls räumlich getrennt, angenrdnct sein. Auch karrt zusätzlich eine Kühlerklapp.enreih.e angebracht werden, die von Hand oder durch ein wärmeempfindliches Glied gesteuert wird.The invention is not restricted to the exemplary embodiment. So Instead of a split cooler, two individual coolers can be used, possibly spatially to be separate, to be connected. A row of radiator flaps is also attached to the cart which is controlled by hand or by a thermosensitive member.
