ENGINE COOLING SYSTEM FOR VEHICLE AND CONTROL METHOD OF THE SAME

摘要

An engine cooling system for a vehicle includes a water pump disposed to supply an engine with a coolant and a radiator disposed to cool heated coolant of the engine by exchanging heat with outside air. The system may include: a control valve that is disposed at one side of the engine to control flow rate and flow passage of coolant; a first passage that connects the control valve with the radiator and connects the radiator with the water pump; a TOC that is disposed between an outlet of the radiator and the water pump to be connected through the first passage; a second passage that connects the TOC with the control valve and directly supplies the TOC with the coolant exhausted from the engine; and a heater that is disposed in a third passage that bypasses the engine to connect the control valve with the water pump.

1. An engine cooling system for a vehicle in which a water pump is disposed to supply an engine with a coolant and a radiator is disposed to cool heated coolant of the engine by exchanging heat with outside air, comprising:
a control valve disposed at one side of the engine to control flow rate and flow passage of coolant; a first passage that connects the control valve with the radiator and connects the radiator with the water pump; a transmission oil cooler (TOC) disposed between an outlet of the radiator and the water pump to be connected through the first passage; a second passage that connects the TOC with the control valve and direct supplies the TOC with the coolant exhausted from the engine; and a heater disposed in a third passage that bypasses the engine to connect the control valve with the water pump.
