Description

Flüssigkeitskühler für Brennkraftmascbinen Die üblichen Rückkühlanlagen, insbesondere von Kraftfahrzeugen, sind durch die nach der Jahreszeit wechselnden Außenlufttemperaturen und Belastungsschwankungen des Motors einer ständigen Veränderung in der Wassertemperatur unterworfen. Urn hier einen Ausgleich zu schaffen, baut man Thermostate ein, die den Kühlwasserkreislauf des Motors zeitweise vom Kühler trennen, so daß das Kühlmittel sowohl im Motor als auch im Kühler nicht mehr zirkuliert. Um eine Zirkulation im Motor wenigstens teilweise zu gewährleisten oder einen Heizkörper zu betreiben, verwendet man auch Thermostate mit Nebenschluß. Solche Einrichtungen haben aber den Nachteil, daß das im Kühler befindliche Kühlwasser zur Zeit des abgesperrten Kühlmittelkreislaufes stark abkühlt und beim Öffnen des Thermostaten plötzliche Unterkühlungen der Zylinder hervorruft, besonders bei starkem Belastungswechsel des Motors. In solchen Fällen öffnet und schließt der Thermostat ununterbrochen, was, wie vielfach an den Fahrzeugen festgestellt wurde, zu einem relativ frühen Verschleiß führt.Liquid cooler for internal combustion engines The usual recooling systems, in particular of motor vehicles, are due to the changing season Outside air temperatures and load fluctuations on the engine are constantly changing Subjected in the water temperature. To create a balance here, builds thermostats that temporarily remove the engine's cooling water circuit from the radiator so that the coolant no longer circulates in either the engine or the radiator. To at least partially ensure circulation in the engine or a radiator To operate, thermostats with a shunt are also used. Such facilities but have the disadvantage that the cooling water in the cooler is shut off at the time Coolant circuit cools down sharply and suddenly when the thermostat is opened Cylinders undercooling, especially when there are major changes in load of the motor. In such cases the thermostat opens and closes continuously, which, as has been noted many times on the vehicles, at a relatively early stage Wear leads.

Es ist auch versucht worden, in normalen Kühlern eine Trennwand und in dieser einen Thermostaten einzubauen. Hierbei besteht der große Nachteil, daß bei geschlossenem Thermostat in dem noch in Betrieb befindlichen Teilblock eine doppelte und höhere Wassergeschwindigkeit entsteht, die hohe Pumpendrücke mit sich bringt, denen man durch den Einbau von Umgehungsleitungen, Sicherheitsventilen usw. zu begegnen suchte. Alle diese Einrichtungen haben den Nachteil, daß die Zirkulation des Kühlwassers im Motor unterbrochen wird und ferner eine Unterkühlung des im stillgelegten Kühlblock befindlichen Kühlwassers erfolgt. Der Wirkungsgrad solcher Einrichtung ist auch insofern ungünstig, als infolge der Luftlamellen eine gewisse Wärmeübertragung auf die danebenliegenden stillgelegten Rohre erfolgt, welche als Hilfskühler wirken. Endlich wird auch die Wasserverteilung bei zugeschaltetem Hauptkühlblock nachteilig beeinflußt, weil durch die bei geöffnetem Thermostat entstehenden Staudrücke unterschiedliche Wassergeschwindigkeiten in den einzelnen Kühlrohren entstehen, die den Gesamtwirkungsgrad herabsetzen.Attempts have also been made to use a partition and in normal coolers to install a thermostat in this. The major disadvantage here is that with the thermostat closed in the sub-block that is still in operation, a double and higher water speed is created, the high pump pressures with it which can be brought about by installing bypass lines, safety valves, etc. sought to meet. All of these facilities have the disadvantage that the circulation the cooling water in the engine is interrupted and also a subcooling of the decommissioned Cooling block located cooling water takes place. The efficiency of such a facility is also unfavorable insofar as a certain amount of heat transfer due to the air lamellae takes place on the adjacent disused pipes, which act as auxiliary coolers. Finally, the water distribution becomes disadvantageous when the main cooling block is switched on influenced because the back pressures that arise when the thermostat is open are different Water velocities arise in the individual cooling tubes that affect the overall efficiency reduce.

Eine gleichartige Anordnung versuchte man auch bei Ölkühlern, die man in zylindrische Mäntel einbaute. Infolge der Unterkühlung des abgeschalteten Hauptkühlnetzes ergaben sich so große Viskositätsunterschiede, daß infolge der Trägheit des Öles die Temperaturregelung zeitweilig versagte. Um diesen Nachteilen zu begegnen, sind Kühler mit doppelten Rohrböden bekanntgeworden, deren Abschaltwirkung fast wirkungslos wurde, weil die Luftlamellen unmittelbar Wärme von Rohr zu Rohr übertragen haben.A similar arrangement was also tried for oil coolers that built into cylindrical shells. As a result of the subcooling of the switched off Main cooling network there were so great differences in viscosity that due to the inertia temperature control of the oil temporarily failed. To counter these disadvantages, have become known coolers with double tube sheets, their shutdown effect almost became ineffective because the air fins transfer heat directly from pipe to pipe to have.

Es liegen ferner Kühlerkonstruktionen vor, die registerartig hintereinander an einer Umgehungsleitung angeordnet sind. Obwohl die einzelnen Elemente nacheinander zuschaltbar sind, haben diese Kühlerbauarten die gleichen Nachteile wie jeder normale Kühler mit Umgehungsleitung. Die benannten Umstände gaben Veranlassung, Kühlerjalousien, verstell-oder abschaltbare Lüfter usw. vorzusehen, die aber einer gewissen Wartung oder selbsttätigen Regelung bedürfen.There are also cooler designs that are in register, one behind the other are arranged on a bypass line. Although the individual elements one after the other can be switched on, these types of coolers have the same disadvantages as any normal one Cooler with bypass line. The named circumstances gave rise to radiator shutters, Provide adjustable or switchable fans, etc., which, however, require a certain amount of maintenance or require automatic regulation.

Diese obengenannten Kühlsysteme werden dadurch verbessert, daß erfindungsgemäß der Flüssigkeitskühler aus mehreren hintereinandergeschalteten, von Kühlflüssigkeit durchströmten Kühlelementen 'besteht, welche über thermostatgesteuerte Regelventile mit einer Umgehungsleitung derart in Verbindung stehen, daß bei niedriger Kühlflüssigkeitstemperatur weniger Kühlelemente von der Kühlflüssigkeit durchflossen werden als bei hoher Temperatur und das letzte oder das erste der hintereinandergeschalteten Kühlelemente ständig von der gesamten Kühlflüssigkeit durchflossen ist. Als Folge dieser Anordnung ergibt sich, daß der Thermostat ähnlich wie ein Flüssigkeitstbermometer mit einer gewissen Trägheit arbeitet, womit eine größtmögliche Lebensdauer und Betriebssicherheit gegeben ist.These above-mentioned cooling systems are improved by the invention The liquid cooler consists of several series-connected coolants through-flow cooling elements' consists, which via thermostat-controlled control valves are in communication with a bypass line in such a way that at low coolant temperature fewer cooling elements are traversed by the coolant than at a high temperature and the last or the first of the series-connected cooling elements continuously is traversed by the entire coolant. As a result of this arrangement results that the thermostat is similar to a liquid thermometer with a certain Inertia works, giving the greatest possible service life and operational reliability is.

Bei kalter Maschine fließt der Kühlmittelstrom im Gleichstrom bzw. Einfachweg, so daß nur ein Teil des Kühlnetzes zur Wirkung kommt. Sobald die gewünschte Betriebstemperatur erreicht ist, erfolgt langsam eine Drosselung durch das Schließen des Thermostaten und eine Beaufschlagung des übrigen Kühlnetzes. Wird die volle Leistung des Kühlers benötigt, ist der Thermostat ganz geschlossen, bei Teillast nur teilweise geöffnet und bei Leerlauf ganz geöffnet. Im ersteren Falle wird als die volle Wassermenge im Umkehrweg durch das gesamte Kühlnetz geleitet, während bei Teillast sich ein im Mehrweg fließender Wasserstrom bildet bzw. bei Leerlauf nur ein einfacher Wasserweg bei voller Wassermenge vorhanden ist. Die im Motor umlaufende Kühlwassermenge bleibt also immer konstant, ,vas besonders bei den Groß-Dieselmotoren sehr wichtig ist. Unter solchen Umständen würde natürlich die Betriebssicherheit des Motors erhöht und jeder Materialverzug sowie ein dadurch bedingter Verschleiß weitgehendst vermieden. Das erste oder das letzte Kühlelement wird vorteilhaft in seiner Kühlfläche so bemessen, daß diese der bei Leerlaufleistung der Brennkraftmaschine abzuführenden Wärme entspricht, damit im gesamten Lastbereich eine stets gleichbleibende Temperatur vorhanden ist.When the machine is cold, the coolant flows in direct current or One way, so that only part of the cooling network is effective. Once the desired Operating temperature is reached, it is slowly throttled by closing the thermostat and a loading of the rest of the cooling network. Will be the full If the cooler needs power, the thermostat is completely closed, at part load only partially open and fully open when idling. In the former case, as the full amount of water is passed through the entire cooling network in the opposite direction, while at partial load, a multi-path water flow is formed respectively. when idling, there is only a simple waterway with full water. the The amount of cooling water circulating in the engine therefore always remains constant, especially with is very important for large diesel engines. In such circumstances, of course, would the operational safety of the engine increases and any material distortion as well as a result caused wear largely avoided. The first or the last cooling element is advantageously dimensioned in its cooling surface so that it is at idle power corresponds to the heat to be dissipated from the internal combustion engine, thus in the entire load range the temperature is always constant.

Die Anordnung und Wirkungsweise wird nachstehend erläutert.The arrangement and mode of operation are explained below.

Abb. 1 zeigt die Anordnung mit hintereinander im Kühlluftstrom liegenden Kühlelementen, Abb. 2 die Anordnung mit nebeneinanderliegenden Kühlelementen.Fig. 1 shows the arrangement with cooling elements lying one behind the other in the cooling air flow, Fig. 2 the arrangement with cooling elements lying next to one another.

Der Kühler nach Abb. 1 arbeitet so, daß gemäß der Pfeillinie 1 das Wasser vom Motor bei 2 eintritt und durch ein starkes Rohr nach unten geführt wird, wo es sich im unteren Wasserkasten 3 verteilt, um dann im Kühlnetz 9 nach oben zu steigen, und im oberen Wasserkasten 4 umkehrt, um im vorderen Kühlnetz 5 weiter abgekühlt zu werden und über Stutzen 6 der Wasserumwälzpumpe des Motors zuzufließen. Diese an sich normale Arbeitsweise des Kühlers ist nun beim Anlaufvorgang des Motors dadurch unterbrochen, daß in der Stirnwand 7 der Wasserkammer des Stutzens 2 ein Thermostat 8 eingebaut ist, der bei Außentemperatur immer offen bleibt und das Kühlnetz 5 direkt mit dem Eintrittsstutzen 2 verbindet. Das vorgeschaltete Kühlnetz 9 ist so abgeschaltet. Der Kühler arbeitet also beispielsweise nur mit der halben Kühlfläche so lange, bis sich das Kühlwasser auf eine gewisse Temperatur, beispielsweise 50' C, erwärmt hat. Hier schließt der Thermostat 8 den Weg gemäß der Pfeillinie 10 ab und das Wasser strömt jetzt gemäß der Pfeillinie 1 durch beide Kühlnetze 9 und 5. Fällt nun durch Unterbelastung oder bei kaltem Wetter die Temperatur unter 50' C, so öffnet der Thermostat 8 wieder und es arbeitet nur die halbe Kühlfläche, so daß auch eine Unterkühlung des Motors vermieden wird, ohne daß eine Jalousie od. dgl. betätigt werden muß. je nach Auslegung der Kühlflächen 5 und 9 zueinander können nun alle Variationen erreicht werden, zumal bei Kühlern, die im Winter mit Frostschutzmitteln gefüllt sind. Außerdem wird das Kühlnetz 9 auch niemals der Kaltluft ausgesetzt, weil diesem immer im Kühlnetz 5 erwärmte Luft zuströmt.The cooler according to Fig. 1 works in such a way that, according to the arrow line 1, the water from the engine enters at 2 and is led down through a strong pipe, where it is distributed in the lower water tank 3 and then rises upwards in the cooling network 9, and reverses in the upper water tank 4 to be cooled further in the front cooling network 5 and zuzufließen of the engine through pipe 6 of the water circulation pump. This normal mode of operation of the cooler is now interrupted during the start-up process of the engine in that a thermostat 8 is installed in the end wall 7 of the water chamber of the nozzle 2 , which always remains open at outside temperature and connects the cooling network 5 directly to the inlet nozzle 2. The upstream cooling network 9 is switched off. So the radiator for example, operates at only half the cooling surface until the cooling water to a certain temperature, such as 50 'C, has warmed. Here the thermostat 8 closes the path according to the arrow line 10 and the water now flows according to the arrow line 1 through both cooling networks 9 and 5. If the temperature falls below 50 ° C due to underload or in cold weather, the thermostat 8 opens again and only half the cooling surface works, so that undercooling of the motor is avoided without a blind or the like having to be operated. Depending on the design of the cooling surfaces 5 and 9 with respect to one another, all variations can now be achieved, especially with coolers that are filled with antifreeze in winter. In addition, the cooling network 9 is never exposed to the cold air, because heated air always flows to it in the cooling network 5.

Bei kleineren Maschinenleistungen werden die Kühler gemäß Abb. 2 ausgeführt. Hier tritt das Kühlmittel bei 11 ein, um dann den Kühler gemäß Pfeillinie 12 zu durchfließen und bei 13 der Pumpe des Motors zuzuströmen. In der Trennwand 14 ist nun ein Thermostat 15 untergebracht, der bei kalter Maschine offen ist, so daß das Kühlmittel den Weg gemäß Pfeillinie 16 durch den Kühler nimmt. Sobald nun das Kühlmittel eine gewisse Temperatur erreicht hat, schließt der Thermostat 15 und das Kühlmittel nimmt seinen Weg gemäß Pfeillinie 12. Die Anordnung ist aber, wie bereits erwähnt, nur für kleinere Anlagen geignet, weil eventuell mit einem so starken Verzug der Kühlnetze infolge der Temperaturunterschiede gerechnet werden muß, daß diese bei größeren Ausführungen reißen.For smaller machine outputs, the coolers are designed as shown in Fig. 2. Here the coolant enters at 11 in order to then flow through the radiator according to the arrow line 12 and to flow to the pump of the motor at 13. In the partition 14, a thermostat 15 is now housed, which is open when the machine is cold, so that the coolant takes the path according to the arrow line 16 through the radiator. As soon as the coolant has reached a certain temperature, the thermostat 15 closes and the coolant takes its path according to arrow line 12. However, as already mentioned, the arrangement is only suitable for smaller systems, because possibly with such a strong delay in the cooling networks as a result of the Differences in temperature must be expected that these tear in larger versions.
