Problems solved by technology

[0005] Also, while there is a way to install an ATF (Automatic Transmission Fluid) heater on the preheat circuit of the engine cooling system, it adds cost and is not very effective
[0006] In addition, when the ATF heater is applied to reduce the friction of the automatic transmission through its rapid warm-up, the coolant flow speed of the heating line decreases, the fuel consumption increases due to the decrease in the heat supplied from the engine to the heater, and must Install a separate bypass channel

Abstract

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.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2012-0147801 filed on December 17, 2012, the entire contents of which are hereby incorporated by reference for all purposes. technical field [0003] The present invention relates to an engine cooling system and a control method for a vehicle to control flow direction and coolant flow rate to provide optimum cooling conditions. Background technique [0004] Coolant temperature is controlled using a motorized water pump or using an electronic thermostat utilizing an electronic heater. [0005] Also, while there is a way to install an ATF (Automatic Transmission Fluid) heater on the preheat circuit of the engine cooling system, it adds cost and is not very effective. [0006] In addition, when the ATF heater is applied to reduce the friction of the automatic transmission through its rapid warm-up, the coolant flow speed of the heating line decreases,...
