ABSTRACT:
A device for moving a radiator grille in automobiles is disclosed. In the device, a plurality of temperature sensors are placed in back of a radiator. The radiator grille has a plurality of directional control fins which are rotatable within a predetermined rotating angle by a fin moving means. The fin moving means is operated under the control of a control unit. The control unit outputs a control signal to the fin moving means in response to temperature signals from the sensors. The fin moving means rapidly moves the directional control fins under the control of the control unit in accordance with a temperature difference on the back surface of the radiator, thus controlling the flowing direction of air guided to the radiator. The radiator grille moving device of this invention improves the cooling effect of the radiator and improves durability of the parts, such as, an engine, arranged in back of the radiator.
