摘要： A cooling device cools a motor mounted on a vehicle and an inverter driving the motor. The cooling device includes: a common flow path through which coolant flows; a first flow path branching from the common flow path and arranged to cool the inverter and a stator of the motor; and a second flow path branching from the common flow path, being independent of the first flow path, and arranged to cool a rotor of the motor. The cooling device further includes a distribution structure configured to distribute the coolant to the first flow path and the second flow path, and to change a distribution ratio of a first coolant distributed to the first flow path out of the coolant and a second coolant distributed to the second flow path out of the coolant.

摘要： A coolant passage of a vehicular cooling system includes a battery coolant passage through which a coolant is supplied from a radiator to a battery, a discharge coolant passage through which the coolant is supplied to the radiator, a first bypass passage through which the coolant is supplied from the discharge coolant passage to the battery coolant passage while bypassing the radiator, and a switching valve that switches a pathway of the coolant, between a first pathway through which the coolant is supplied from the discharge coolant passage to the battery coolant passage via the radiator and a second pathway through which the coolant is supplied from the discharge coolant passage to the battery coolant passage via the first bypass passage. An electronic control unit controls the switching valve such that the pathway is switched to the second pathway at the time of increasing a temperature of the battery.
