ABSTRACT:
A fan frame provides fixing parts extending downward to embrace a radiator with a hook end catching lower side of the radiator respectively. A guard device is disposed on the frame with hard skeletons to surround a fan wheel so that fluid can enter the radiator via the openings. Hence, the openings of the guard device can increase flow rate of the fluid entering the radiator, decrease noise and prevent foreign objects entering the fan wheel.
