Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous developments of the invention are the subject of the dependent claims.
Bei der Vorrichtung zur thermischen Kopplung zumindest zweier Kühlkreisläufe in einem Fahrzeug sind die Kühlkreisläufe jeweils mittels zumindest eines Wärmetauschers mit einem Strahlkältekreislauf thermisch gekoppelt. Dadurch ist der erste Kühlkreislauf vorteilhafterweise auf Temperaturen unterhalb der Temperaturen im zweiten Kühlkreislauf, welcher vorzugsweise als Niedertemperaturkreislauf ausgebildet ist, abkühl- und insbesondere unterkühlbar.In the device for the thermal coupling of at least two cooling circuits in a vehicle, the cooling circuits are each thermally coupled by means of at least one heat exchanger with a jet cooling circuit. As a result, the first cooling circuit is advantageously cooled to temperatures below the temperatures in the second cooling circuit, which is preferably designed as a low-temperature circuit, and in particular undercooled.
Beim Verfahren zur thermischen Kopplung zumindest zweier Kühlkreisläufe in einem Fahrzeug werden die Kühlkreisläufe jeweils mittels zumindest eines Wärmetauschers mit einem Strahlkältekreislauf thermisch gekoppelt und/oder zwei Kühlkreisläufe werden mittels eines Wärmetauschers direkt thermisch miteinander gekoppelt.In the method for the thermal coupling of at least two cooling circuits in a vehicle, the cooling circuits are each thermally coupled by means of at least one heat exchanger with a jet cooling circuit and / or two cooling circuits are thermally coupled directly by means of a heat exchanger.
Die Erfindung verbessert vorteilhafterweise die Kühlung im ersten Kühlkreislauf, welcher vorzugsweise als Klimaanlagen- oder Ladeluftkühlkreislauf ausgebildet ist.The invention advantageously improves the cooling in the first cooling circuit, which is preferably designed as an air conditioning or charge air cooling circuit.
Besonders vorteilhafterweise ist eine Absenkung des Temperaturniveaus im ersten Kühlkreislauf unterhalb der Werte möglich, welche mittels einer herkömmlichen direkten thermischen Kopplung des ersten und des zweiten Kühlkreislaufs erreichbar sind.Particularly advantageously, it is possible to lower the temperature level in the first cooling circuit below the values which can be achieved by means of conventional direct thermal coupling of the first and second cooling circuits.
