  • Cooling control device and cooling control method for internal combustion engine
    Patent number: 10436101
    Abstract: A cooling control device for an internal combustion engine has an internal coolant passage formed in the internal combustion engine, external coolant passages formed outside the internal combustion engine and connected to the internal coolant passage, the cooling control device performing coolant passage switching in which the internal coolant passage and a certain one of the external coolant passages are connected to or disconnected from each other by a circuit switching mechanism, a branching passage that sends coolant in the internal coolant passage to one of the external coolant passages which passes through a radiator, when the circuit switching mechanism has a failure and fails in circuit switching of connecting the internal coolant passage and the external coolant passage passing through the radiator to each other, and a wax-type thermostat provided in the branching passage that opens the branching passage when the internal combustion engine is excessively heated.
