VEHICLE COOLING SYSTEM
Document Type and Number:
Japanese Patent JP2022114090
Kind Code:
A
Abstract:
To provide a vehicle cooling system that determines the level of priority in cooling a battery, a PCU, and the air inside a vehicle cabin, depending on the situation, to thereby cool the battery, the PCU, and the air inside the vehicle cabin with favorable balance.SOLUTION: There is provided a vehicle cooling system including: a refrigeration cycle device 20 having a battery heat exchanger 25, an evaporator 26 disposed parallel to the battery heat exchanger 25, and a condenser 22 for being cooled with airflow; and a cooling device 40 having a radiator 43 for cooling a PCU 14 with a coolant, the radiator being disposed downstream of airflow of the condenser 22, and cooling the coolant. In a case where the temperature of a battery 13 is equal to or higher than a predetermined temperature, the battery 13 is cooled with priority. In a case where the temperature of the coolant of the PCU 14 is equal to or higher than the predetermined temperature, the PCU 14 is cooled with priority. In a case where the temperature of the battery is less than the predetermined temperature and the temperature of the coolant of the PCU 14 is less than the predetermined temperature, the air inside a vehicle cabin is cooled with priority.SELECTED DRAWING: Figure 1
