An engine cooling system includes: an engine system including an engine having a plurality of combustion chambers that generate a driving force by combustion of fuel; a power electronics (PE) device that assists engine torque of the engine system in accordance with a driving state of the vehicle; a main radiator connected to the engine system by an engine coolant line and discharging heat generated in the engine system by engine coolant flowing in the engine coolant line, a sub-radiator connected to the PE device through a PE coolant line and discharging heat generated in the PE device by PE coolant flowing in the PE coolant line; a 2-way valve connecting the engine coolant line and the PE coolant line to each other; and a controller for controlling opening and closing of the 2-way valve according to a temperature of the engine coolant and a vehicle driving condition.

Engine cooling system for vehicle

A heating, ventilation and air conditioning (HVAC) system of a vehicle includes: an indoor air conditioning circuit which produces to supply cooling air to a vehicle interior by heat-exchanging inflow air through an indoor air inlet or an outdoor air inlet with an evaporator, and which produces to supply warm air to the vehicle interior or to discharge to the outside of the vehicle interior by heat-exchanging inflow air with a heat exchanger. The heat exchanger is connected with an engine cooling circuit so that engine coolant is used as a heat source of the heat exchanger, thereby improving the cooling performance of the ERG cooler.

Heating, ventilation and air conditioning system of vehicle

An apparatus for improving cooling performance of an engine room in a vehicle, may include an air duct connected to an air cleaner to serve as a moving guide of fresh air; a duct flap installed to open and close some section of the air duct and operated to supply all the fresh air introduced into the air duct when the air duct is in a closed state to the air cleaner and discharge some of the fresh air introduced into the air duct when the air duct is in an opened state to a space of a high temperature part of the engine room; and an actuator supplying power to the duct flap to perform an opening and closing operation of the duct flap.
