Cooling system for vehicles and control method thereof

[0022]Exemplary embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

[0023]FIG. 1 is a view illustrating a configuration of a cooling system for vehicles according to the present disclosure. An inlet water temperature sensor WTS2 is installed on a flow path of an inlet side of an engine and an outlet water temperature sensor WTS1 is installed on a flow path of an outlet side of the engine.

[0024]In addition, a flow rate control valve 1 is installed at a rear end of the outlet water temperature sensor WTS1. Such a flow rate control valve 1 may variably control four ports at one time by an operation of only a valve body included in the valve.

[0025]For example, the flow rate control valve 1 is provided with at least three or more discharge ports. The respective discharge ports may be each connected to flow paths on which a radiator 30, an oil heat exchanger such as oil warmer 40, or the like, and a heater core 50 are disposed, the...
