A cooling apparatus for a vehicle includes a cooling module connected to the cooling apparatus through a cooling line to cool a driving system. The cooling module includes, according to the amount of heat transfer and operation temperature, an aircon condenser disposed behind of a radiator grill. A radiator for an electromotive device is disposed in parallel under the aircon condenser behind of a bumper hole through which a large amount of outside air is introduced. A radiator for a stack is disposed behind of the aircon condenser, and a radiator for an electromotive device is disposed in parallel. A cooling fan is disposed behind of the radiator for a stack. The cooling apparatus includes an air guide unit mounted in front of the aircon condenser and the radiator for an electromotive device, the air guide unit preventing the bypassing of outside air introduced during operation of a vehicle while distributing and introducing the outside air. Accordingly, to improve the cooling performance of the cooling module, the aircon condenser and the radiator for an electromotive device are configured in parallel, and the radiator for a stack is disposed behind, according to the amount of heat transfer and operation temperature, so that outside air introduced from the outside of the vehicle is efficiently distributed and supplied and is then cooled, thus improving cooling efficiency and ensuring the cooling performance.
