Description

2525th

Die Erfindung bezieht sich auf eine Flüssigkeitskühlanlage für aufgeladene Brennkraftmaschinen, insbesondere zum Antrieb von Lokomotiven, mit je einem Kühlkreis zum Abführen der Motorwärme und zum Kühlen der Ladeluft.The invention relates to a liquid cooling system for supercharged internal combustion engines, in particular to drive locomotives, each with a cooling circuit to dissipate the engine heat and for cooling the charge air.

Bei den bekannten Flüssigkeitskühlanlagen für aufgeladene Brennkraftmaschinen dieser Art ist nur ein in einem besonderen Kühlwasserkreislauf liegender Ladeluftkühler vorgesehen, mit dem nur eine begrenzte Kühlung der Ladeluft und damit nur begrenzte Verdichtung in dem Zylinder und Leistungssteigerung der Maschine erreicht wird.In the known liquid cooling systems for supercharged internal combustion engines of this type is only a charge air cooler located in a special cooling water circuit is provided, with which only a limited one Cooling of the charge air and thus only limited compression in the cylinder and increase in performance the machine is reached.

Es sind ferner Flüssigkeitskühlanlagen bekannt, bei denen die die Austrittsleitung des Motorkühlsystems über eine abgezweigte Leitung und einen Thermostaten an die Saugseite der in der Eintrittsleitung für den Kühlwasserkreislauf des Ladeluftkühlers liegenden Pumpe und die Austrittsleitung des Ladeluftkühlers an die Saugseite der in der Eintrittsleitung des Motorkühlsyste'ms liegenden Pumpe angeschlossen sind. Dieses ist zu dem Zweck vorgesehen, bei tiefen Außentemperaturen ein Einfrieren des Kühlwassers im Ladeluftkühler dadurch zu verhindern, daß der Thermostat unterhalb einer bestimmten, eingestellten Temperatur den Zufluß von warmem Motorkühlwasser zu dem Ladeluftkühler gestattet.There are also known liquid cooling systems in which the outlet line of the engine cooling system Via a branched line and a thermostat to the suction side of the inlet line for the cooling water circuit of the charge air cooler and the outlet line of the charge air cooler connected to the suction side of the pump located in the inlet line of the motor cooling system are. This is provided for the purpose of freezing the cooling water at low outside temperatures in the intercooler to prevent that the thermostat is below a certain, set Temperature allows the flow of warm engine cooling water to the intercooler.

Der Erfindung liegt die Aufgabe zugrunde, die Kühlung der Ladeluft, insbesondere für diese Lokomotiven zu verbessern. Dies wird gemäß der Erfindung dadurch erreicht, daß als erste Kühlstufe für die Ladeluft ein vom Motorkühlwasser im Nebenstrom durchflossener Wärmetauscher vorgesehen ist. Durch den als erste Kühlstufe für die Ladeluft wirkenden Wärmetauscher wird es möglich, die Ladeluft auf eine besonders hohe Temperatur zu verdichten, um damit eine Leistungssteigerung des Motors zu erzic-Il1H, während die Tatsache, daß der Wärmetauscher durch das Mototkühlwasser im Nebenstrom durchflossen wird, eine einwandfreie Kühlung des Motors ohne übermäßige Belastung der Kühler des Motorkühlkreises und des Wärmetauschers des Ladeluftkühlkreises gewährleistet ist.The invention is based on the object of improving the cooling of the charge air, in particular for these locomotives. This is achieved according to the invention in that a heat exchanger through which the engine cooling water flows in the bypass flow is provided as the first cooling stage for the charge air. Through the first cooling stage acting for the charge air heat exchanger, it becomes possible to compress the charge air to a particularly high temperature, thereby an increase in output of the engine to erzic-Il 1 H, while the fact that the heat exchanger traversed by the Mototkühlwasser in the bypass flawless cooling of the engine without excessive load on the radiator of the engine cooling circuit and the heat exchanger of the charge air cooling circuit is guaranteed.

In der Zeichnung ist die Flüssigkeitskühlanlage nach der Erfindung in einem Ausführungsbeispiel dargestellt.In the drawing, the liquid cooling system according to the invention is in one embodiment shown.

Die Flüssigkeitskühlanlage für aufgeladene' Brennkraftmaschinen 2 weist einen Kühlkreis 4 von hoher Temperatur zum Abführen der Motorwärme, einen Kühlkreis 6 von niederer Temperatur zum Kühlen der Ladeluft und einen von dem Motorkühlwasser im Nebenstrom durchflossenen Kreislauf 8 auf.The liquid cooling system for supercharged internal combustion engines 2 has a cooling circuit 4 of high Temperature to dissipate the engine heat, a cooling circuit 6 of low temperature for cooling the charge air and a circuit 8 through which the engine cooling water flows in the bypass flow.

Der Kühlkreis 4 zum Abführen der Motorwärme enthält wenigstens einen Kühler oder eine Gruppe von Kühlern 10, eine Pumpe 12, die Wassermäntel des Motors und die Anschlußleitungen 14, 16, 18.The cooling circuit 4 for dissipating the engine heat contains at least one cooler or a group of radiators 10, a pump 12, the water jackets of the engine and the connecting lines 14, 16, 18.

Der Kühlkreis 6 zum Kühlen der Ladeluft enthält mindestens einen Kühler oder eine Gruppe von Kühlern 20, eine Pumpe 22, einen Wärmeaustauscher Wasser/Öl 24, welcher die Kühlung des Motorschmieröles sicherstellt (die das öl zu dem Wärmeaustauscher führenden Leitungen sind nicht dargestellt), und einen Wärmeaustauscher Wasser/Ladeluft 26, welcher die Stufe niedriger Temperatur eines Wärmeaustauschers 28 bildet, welcher die durch den nicht dargestellten Ladeluft-Turbokompressor des Motors geblasene Luft kühlt. Der Kühlkreislauf wird durch Anschlußleitungen 30, 32, 34, 36 geschlossen. The cooling circuit 6 for cooling the charge air contains at least one cooler or a group of coolers 20, a pump 22, a heat exchanger water / oil 24, which cools the engine lubricating oil ensures (the lines leading the oil to the heat exchanger are not shown), and a heat exchanger water / charge air 26, which has the low temperature stage Heat exchanger 28 forms, which by the charge air turbo compressor, not shown, of the Air blown from the engine cools. The cooling circuit is closed by connecting lines 30, 32, 34, 36.

An dem im Nebenstrom durchflossenen Kühlkreislauf 8 ist ein Wärmeaustaucher Wasser/Ladeluft 38 vorgesehen, welcher die erste Kühlstufe für die Ladeluft bildet, wobei dieser Wärmeaustauscher 38 im Nebenschluß zu dem Motorkühlwasserkreis mittels zweier Leitungen 40, 42 liegt.A heat exchanger water / charge air 38 is located on the cooling circuit 8 through which the bypass flow flows provided, which forms the first cooling stage for the charge air, this heat exchanger 38 in shunt to the engine cooling water circuit by means of two lines 40, 42.

Die beiden Kühler oder Kühlergruppen 20, 10 sind paarweise, d. h. hintereinander angeordnet und werden nacheinander durch den von einem Ventilator 44 eingesaugten Luftstrom durchflossen.The two coolers or cooler groups 20, 10 are in pairs, i. H. arranged one behind the other and flowed through one after the other by the air stream sucked in by a fan 44.

Die Abzweigung des neuen Kreislaufes 8 im Nebenschluß zu den Kühlern 1,0 zeigt zahlreiche Vorteile; tatsächlich durchläuft die Gesamtheit der Austrittsmenge der Pumpe 12 die Kühlwassermäntel des Motors, was von Vorteil ist, um die Bildung von Wärmepuhkten oder Wärmestellen zu vermeiden, da der Teil 14, 10, 16 nur von einem Bruchstück dieser Leistung, beispielsweise in der Größenordnung von der Hälfte durchlaufen wird. Es folgt daraus, daß der Querschnitt der Leitungen 14 und 16, welche lang sind, verkleinert werden kann, was sehr wirtschaftlich ist und die Montage erleichtert, und gleichzeitig, daß die Kühler hoher Temperatur 10 nicht mehr einem starken und übermäßigen Durchsatz unterworfen sind. Der andere Bruchteil der Austrittsmenge der Pumpe 12, das würde also heißen, die andere Hälfte läuft durch die Ergänzungsleitungen 40, 42 des abgeleiteten Kreislaufes, aber diese Leitungen sind äußerst kurz (zwischen dem Motor und dem Eintritt der Vorverdichtungsluft) und somit wenig kostspielig.The branching of the new circuit 8 in the shunt to the coolers 1.0 shows numerous advantages; in fact, all of the discharge from the pump 12 passes through the cooling water jackets of the Motors, which is an advantage in order to avoid the formation of heat puffs or hot spots, there the part 14, 10, 16 only from a fraction of this power, for example of the order of halfway through. It follows that the cross-section of the lines 14 and 16, which are long are, can be reduced in size, which is very economical and facilitates assembly, and at the same time that the high temperature coolers 10 no longer subject to high and excessive throughput are. The other fraction of the discharge quantity of the pump 12, that would mean the other half runs through supplemental lines 40, 42 of the diverted circuit, but these lines are extreme short (between the engine and the entry of the pre-compression air) and therefore not very expensive.

Andererseits ist der Wärmeaustauscher 28 in zwei Stufen nicht viel aufwendiger als der einzige Wärmeaustauscher, welcher bei den klassischen Kühlsystemen vorhanden ist.On the other hand, the two-stage heat exchanger 28 is not much more expensive than the single heat exchanger, which is available in classic cooling systems.

Da ein Teil der Kalorien oder Wärmeeinheiten der Vorverdichtungsluft durch den neuen abgeleiteten Kreislauf 8 abgeführt wird, braucht die Austrittsmenge oder Leistung der Pumpe 22 des Kreislaufes tiefer Temperatur 6 nicht so groß wie bei den klassischen Kühlsystemen zu sein, so daß man eine Ersparnis bei der Pumpe und bei dem Querschnitt der Leitungen 30, 32, 34, 36, welche lang sind, erzielen kann.Because some of the calories or heat units of the pre-compression air are derived by the new one Circuit 8 is discharged, needs the discharge amount or power of the pump 22 of the circuit lower temperature 6 not to be as great as with the classic cooling systems, so that one savings with the pump and with the cross-section of the lines 30, 32, 34, 36, which are long can.

Die Verteilung der Austrittsmenge der Pumpe 12 zwischen den beiden Kreisläufen 14, 10, 16 und 42, 38, 40 wird derart gewählt, daß man einen thermischen Ausgleich zwischen den Kreisläufen hoher Temperatur und tiefer Temperatur erhält, wobei diese Verteilung der Menge nach den Belastungsverlusten in den beiden Kreislaufabzweigungen geschieht und beispielsweise mittels eines oder zweier Einstellvorrichtungen 50, 50' für den gewählten Querschnitt eingestellt werden kann.The distribution of the discharge quantity of the pump 12 between the two circuits 14, 10, 16 and 42, 38, 40 is chosen in such a way that there is a higher thermal balance between the circuits Temperature and low temperature is maintained, this distribution of the amount according to the load losses happens in the two circuit branches and for example by means of one or two adjustment devices 50, 50 'can be set for the selected cross-section.
