Abstract: A thermal circuit having a main conveying direction for a thermal management system of an electrified vehicle, the thermal circuit including a main circuit with a main circuit first conduit portion having a first pump and a heat exchanger provided behind the first pump and a main circuit second conduit portion. The thermal circuit includes a partial circuit with a partial circuit first conduit portion having a second pump and a component arranged to be temperature-controlled behind the second pump and a partial circuit second conduit portion. The thermal circuit further includes a connecting valve connected to the main circuit first conduit portion or the partial circuit first conduit portion and the main circuit second conduit portion or the partial circuit second conduit portion for controlling a volume flow. The thermal circuit includes a first fluid connection connected to the connecting valve, and a second fluid connection.

Abstract: A method for operating a cooling system of a motor vehicle for cooling at least one component, a cooling system of a motor vehicle for cooling at least one component, and a motor vehicle having such a cooling system. The cooling system has a coolant circuit and a refrigerant circuit. The coolant circuit serves for cooling the at least one component and the refrigerant circuit and the coolant circuit are coupled thermally to one another via a heat exchanger. The coolant circuit has a conveying device for conveying a coolant in the coolant circuit. A cooling power of the refrigerant circuit can be regulated. The regulation of the cooling power of the refrigerant circuit is realized in a manner dependent on a return temperature of the coolant and/or on a temporal development of the return temperature of the coolant.
