Cooling system

A cooling system for a vehicle, comprising:

• a cooling circuit through which a coolant is flowable;
• a hydraulic switch dividing the cooling circuit into a first partial circuit and a second partial circuit;
• the first partial circuit including:
• a first heat source;
• a first radiator;
• a first pump;
• a warming-up bypass line connected in parallel with the first heat source and through which the coolant is flowable to bypass the first heat source;
• and
• a warming-up bypass valve via which the warming-up bypass line is openable and closable;
• the second partial circuit including:
• a second heat source;
• a second radiator;
• a second pump;
• a radiator bypass line connected in parallel with the second radiator and through which the coolant is flowable to bypass the second radiator;
• a radiator bypass valve via which the radiator bypass line is openable and closable;
• a heat source bypass line connected in parallel with the second heat source and through which the coolant is flowable to bypass the second heat source;
• and
• a heat source bypass shut-off valve via which the heat source bypass line is openable and closable;
• and
• wherein, in the cooling circuit, the first heat source, the first radiator, the second heat source, and the second radiator are connected in series with one another.

A method for operating a cooling system for a vehicle, the cooling system including a cooling circuit through which a coolant is flowable;

• the cooling circuit including a first heat source coolable at a lower temperature level, a first radiator, a second heat source coolable at a higher temperature level, a second radiator, a first pump, a second pump, and a hydraulic switch;
• the first heat source, the first radiator, the second heat source, and the second radiator connected in series with one another in the cooling circuit;
• the hydraulic switch dividing the cooling circuit into (i) a first partial circuit with the first heat source, the first radiator, and the first pump and (ii) a second partial circuit with the second heat source, the second radiator, and the second pump;
• the first pump and the second pump connected in series;
• the method comprising:
• operating the cooling system in at least one of a braking mode, a normal operating mode, and a warming-up mode;
• wherein the cooling system is operated in the braking mode;
• and
• wherein operating the cooling system in the braking mode includes:
• switching on the first pump and the second pump;
• regulating a flow and a mixing of the coolant in the hydraulic switch dependent on at least one of an adjusted pump pressure, an adjusted rotational speed, and an adjusted mass flow of the first pump and the second pump;
• flowing the coolant in the hydraulic switch from a first inlet to a first outlet and from a second inlet to a second outlet;
• and
• flowing a first part of the coolant through the first partial circuit and flowing a second part of the coolant through the second partial circuit such that the first partial circuit and the second partial circuit are separated hydraulically.
