Abstract:
1. A cooling apparatus for a hybrid vehicle, the hybrid vehicle comprising: an internal combustion engine for driving the hybrid vehicle; a motor as a power source for driving the hybrid vehicle together with the internal combustion engine, and a motor control device for controlling an operation of the motor; and the cooling apparatus for the hybrid vehicle comprising: a cooling circuit for cooling said internal combustion engine and said motor control device by a common coolant, and cooling said coolant by radiating heat using a radiator, said cooling circuit including, a first flow path, through which coolant for cooling the internal combustion engine flows, and a second flow path, through which the coolant for cooling the motor control device flows, branched from the first flow path at a location inside of the radiator, further the second flow path is again merged into the first flow path downstream of the motor control device, and the merged coolant is circulated by a water pump provided downstream of the merged portion, the cooling apparatus for the hybrid vehicle further comprising: a temperature setting device in which the coolant circulating in the second flow path which is branched from the first flow path at the location inside of the radiator is further cooled, and thereby a management temperature of the coolant at said internal combustion engine and a management temperature of the coolant at said motor control device are independently set.
