Description

Kühlanlage, insbesondere Heißdampfkühlanlage, für Brennkraftmaschinen Die Erfindung bezieht sich auf eine Kühlanlage, insbesondere eine Heißdampfkühlanlage, für Brennkraftmaschinen.Cooling system, in particular superheated steam cooling system, for internal combustion engines The invention relates to a cooling system, in particular a superheated steam cooling system, for internal combustion engines.

Bei der Heißdampfkühlung wird bekanntlich der Kühlmitteldampf in einem Kondensator, der auch ein Oberflächenkondensator sein kann, als Kühlmittel zurückgewonnen und der Maschine wieder zugeführt. Dabei kann es vorkommen, daß das Kondensat bei einem geringen Anfall in der Rückführungsleitung zu einem Sammelbehälter oder zur Maschine einfriert, obwohl der flüssige Kühlmittelkreislauf, dem ein Gefrierschutzmittel zugesetzt worden ist, nichteinfriert. Auch der Kondensatvorratsbehälter selbst kann bei Stillstand der Maschine und Nichtablassen des Kondensates einfrieren, weil das Gefrierschutzmittel nicht mitverdampft und zum Kondensator solches nicht hingelahgt. Nach der Erfindung soll das Einfrieren von Kondensat in der Rückleitung oder im Vorratsbehälter dadurch verhindert werden, daß dem Kondensator das beim Verdampfen des flüssigen Kühlmittels nicht mitverdampfende Gefrierschutzmittel wieder zugeführt wird. Zu diesem Zweck wird flüssiges Kühlmittel aus dem Kühlflüssigkeitskreislauf, das das Gefrierschutzmittel enthält, in den Kondensator Moder in die Kondensatrückführleitung eingeführt.In the case of superheated steam cooling, it is known that the coolant steam is in one Recovered condenser, which can also be a surface condenser, as a coolant and fed back into the machine. It can happen that the condensate at a small amount in the return line to a collecting tank or to Machine freezes, although the liquid coolant circuit, which is an antifreeze has been added does not freeze. The condensate storage tank itself can also freeze when the machine is at a standstill and the condensate is not drained, because that Anti-freeze does not evaporate as well and it does not lie in the condenser. According to the invention, the freezing of condensate in the return line or in Reservoir can be prevented that the condenser when evaporating of the liquid coolant, antifreeze agents that do not evaporate are fed back will. For this purpose, liquid coolant is extracted from the coolant circuit, which contains the antifreeze, in the condenser Moder in the condensate return line introduced.

In der Zeichnung ist die Erfindung in einem Ausführungsb#eispiel planmäßig dargestellt. Flüssiges Kühlmittel tritt in die Kühlräume einer Maschinea mit hängenden Zy- lindern in V-Form durch die Leitungb ein und durch die Leitung c aus, wobei eine Kühl.-mittelpumped das mit einem nicht verdampfenden Gefrierschutzmittel versehene Kühlmittel über eine Leitung e aus dem Vorratsbehälterf fördert. Die Rückleitungc mündet in einen Dampfabscheider g ein, und dessen Flüssigkeitsablauf k mündet wieder in den Vorratsbehältür f. Die Dampfableitung i führt nach dem Kondensator k, und von diesem führt eine Kondensatrückleitung 1 über eine Rückführpumpe in ebenfalls nach dem Behälter j zurück. Außerdem kann in die Rückleitungt, zweckmäßig vor der Pump-ein, ein Kondensatvorratsbehältern angeordnet sein. Weiterhin zweigt von dem Vorratsbehälterl eine ebenfalls nach dem Kondensatork füh- rende Leitungg ab, in welche eine Fürderpumpep eingeschaltet ist.The invention is shown systematically in an exemplary embodiment in the drawing. Liquid coolant enters the cold rooms of a machinea with hanging cylinders in V shape through line b and exits through line c, a coolant pump conveys the coolant, which is provided with a non-evaporating antifreeze, via line e from the storage containerf . The return line c opens into a vapor separator g , and its liquid outlet k flows back into the storage container f. The vapor discharge line i leads to the condenser k, and from this a condensate return line 1 leads back to the container j via a recirculation pump. In addition, a condensate storage tank can be arranged in the return line, expediently upstream of the pump-in. Furthermore, branches from the Vorratsbehälterl from a Rende Leitungg leadership also after Kondensatork into which a Fürderpumpep is turned on.

Die Wirkungsweise der geschilderten Anordnung ergibt sich aus der Abbildung ohne weiteres. Die Pumpeb saugt über die Leitunge aus dem Behälter/ das mit nicht verdampfendem Gefrierschutzmittel vermengte Kühlmittel an und führt es über die Leitung b der Maschinea zu. Das heiße Kühlmittel fließt aus der Leitunge durch den Dampfabscheider g und über die Leitung li nach dem Behälter j zurück. Der Kühlmitteldampf strömt durch die Leitung i nach dem Kondensator k ab, und die Kondensatflüssigkeit fließt durch die Leitungl entweder in den Vorratsbehältern oder unmittelbar über die Pumpe m nach dem Behälter/ zurück. Um das Einfrieren des an sich von Gefrierschutzmittel freien Kondensates in der Leitung 1 oder im Behältern zu verhindern, führt die Pumpe p mit Gefrierschutzmittel versehenes Kühlmittel durch die Leitung o nach dem Kondensator k. The mode of operation of the described arrangement is evident from the figure. The pumpeb sucks in the coolant mixed with the non-evaporating antifreeze from the container via the conduit b and supplies it to the machine a via the conduit b . The hot coolant flows out of the conduit through the vapor separator g and back to the container j via the conduit li. The coolant vapor flows through the line i after the condenser k , and the condensate liquid flows through the line 1 either into the storage tanks or directly via the pump m to the tank / back. To the freezing of the free per se of antifreeze to prevent condensate in line 1 or in containers case brings the pump P with antifreeze coolant provided through the line after the condenser o k.

Gegebenenfalls kann man auch von der Leitung b der Pumpe d aus über eine Drosselstelle, welche regelbar ist, eine Abzweigleitung nach dem Kondensator k führen, welche diesen mit Gefrierschutzmittel enthaltendem Kühlmittel versorgt. Doch ist wegen der Empfindlichkeit der Förderpumpe und der dadurch bedingten Schwierigkeit der Regelung in Anpassung an die wechselnden Betriebsverhältnisse die durch die Abbildung dargestellte Anordnung vorzuziehen. Die Pumpenanordnung kann auch durch eine geeignete Strahleinrichtung ersetzt werden.If necessary, it is also possible to lead a branch line to the condenser k from the line b of the pump d via a throttle point which can be regulated and which supplies it with coolant containing antifreeze. However, because of the sensitivity of the feed pump and the resulting difficulty in regulating it to adapt to the changing operating conditions, the arrangement shown in the figure is to be preferred. The pump arrangement can also be replaced by a suitable jet device.
