The present invention relates to a cooling apparatus for a fuel battery vehicle including a fan motor (100), a cooling fan (200), and a shroud (300). A housing of the fan motor (100) is configured to be watertight; heat dissipation fins (130) are arranged to have a unique structure inducing air flow for effective cooling in the fan motor (100); an air inlet (211) is formed in a hub (210) of the cooling fan (200); and a hub blade (210aa) is formed on one side of the air inlet (211), cut and bent in an inward direction of the hub (210) from a front portion (210a) of the hub (210), and rotates air, which is introduced in the inward direction of the hub (210) through the air inlet (211), in a certain direction. According to the cooling apparatus for a fuel battery vehicle, both heat dissipation characteristics and watertightness of the high voltage fan motor applied to the cooling apparatus for a fuel battery vehicle can be achieved. |
