Abstract:
A cooling device for an internal combustion engine of a vehicle according to the claimed invention includes: an electric water pump; a first path including a cooling water passage in a cylinder head and extending through a heater core for air heating and a radiator; and a second path bypassing the heater core and radiator. When the internal combustion engine is automatically stopped while the vehicle is stopping, the cooling device causes the electric water pump to operate, and increases the cooling water circulation ratio through the first path while reducing the cooling water circulation ratio through the second path. Thereby, the cooling device improves fuel economy during acceleration at the vehicle start from the automatic stop state of the internal combustion engine while suppressing the deterioration of the air heating performance during the automatic stop of the internal combustion engine while the vehicle is stopping.

Claim (Index 11):
A cooling device for an internal combustion engine of a vehicle, comprising:\n an electric water pump for circulating cooling water; a first path including a cooling water passage in a cylinder head and extending through a heater core for vehicle air heating and a radiator; a second path bypassing the heater core and the radiator; path switching means for controlling an opening area of the second path; and control means which, when the internal combustion engine is automatically stopped while the vehicle is stopping, causes the electric water pump to operate and causes the path switching means to reduce the opening area of the second path as compared to before the internal combustion engine is automatically stopped, wherein the second path extends through at least one of a heat exchanger for oil of the internal combustion engine and a heat exchanger for oil of a powertrain for the internal combustion engine, and when the internal combustion engine is automatically stopped, the control means reduces the opening area of the second path such that the lower the temperature of the oil, the greater a reduction amount of the opening area of the second path.
