Beschreibung
Zusammenfassung:	A cooling control device includes a first heat exchanger to which a coolant of an internal combustion engine is supplied, a radiator to which the coolant of is supplied, a coolant pump supplying the coolant, a flow amount control valve controlling a flow amount of the coolant, and a control unit controlling the flow amount control valve. The control unit acquires a first amount of heat which is accumulated in the coolant, a second amount of heat which is accumulated in the coolant by a heat exchange with the first heat exchanger, and a third amount of heat for changing a temperature level of the coolant to a targeted temperature level. A targeted dissipation amount is set from the first, second and third amounts of heat, and an opening of the flow amount control valve is set by a feedforward control.
