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: An expansion tank arrangement is for a cooling circuit. The expansion tank arrangement has: an expansion tank having a housing with an internal volume configured to receive a cooling fluid; a fluid connection configured to connect the expansion tank to the cooling circuit for supplying the cooling fluid; and a pneumatic connection configured to connect the expansion tank to a pneumatic supply device for pressurizing the expansion tank with a pneumatic medium using a pneumatic supply line. A valve that is configured to influence the pressurization of the expansion tank is in the pneumatic supply line between the expansion tank and the pneumatic supply device.
