Cooling apparatus for hybrid vehicle
First Claim
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 the 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 common coolant; and
a temperature setting device for setting independently a temperatures a management temperature of the internal combustion engine and the management temperature of the said motor control device.

Abstract
In order to appropriately control the temperature state of multiple equipment having differing management temperatures, while preventing complication of the apparatus structure, a cooling apparatus for a hybrid vehicle is provided with a seventh flow path 30g which flows coolant which has flowed only through a main flow path 22a of a radiator 22 to a water jacket 25 via a first thermostat 23 which has an induction temperature set relatively high; an eighth flow path 30h which flows coolant which has flowed through the main flow path 22a and a sub flow path 22b of the radiator 22 to the water jacket 25 via a second thermostat 24 which has an induction temperature set relatively low, and also supplies the coolant to a PDU 14 and a downverter 15; and a bypass flow path 30j which connects a fifth flow path 30e which supplies coolant discharged from the water jacket 25 to the radiator 22, and a position of the eighth flow path 30h on a downstream side of the second thermostat 24.
