Abstract
The present invention relates to a cooling device and a control method for the same. This cooling device includes: a first cooling liquid line routed by way of a cylinder head and a radiator; a second cooling liquid line routed by way of a cylinder block while bypassing the radiator; an electric flow rate control valve whose inlet is connected to the first and second cooling liquid lines, and whose outlet is connected to the intake side of an electric water pump; and a bypass line that branches off from the first cooling liquid line at a point between the cylinder head and the radiator and that joins to the outlet of the flow rate control valve while bypassing the radiator. A control unit controls the flow rate control valve according to the temperature of the cylinder head and the temperature of the cylinder block.
