PURPOSE: A radiator fan is provided to increase the heat dissipation because high temperature heat of a LED head lamp is emitted to outside through a connecting tube by a strong suction force through a centrifugal impeller when the radiator fan rotates by forming the centrifugal impeller in a side part of the fan. CONSTITUTION: A radiator fan comprise a rotary shaft(110) and an impeller unit(120). The rotary shaft comprises a plurality of vanes(111). The impeller unit is formed into a shape covering the plurality of vanes. A centrifugal impeller is formed along the outer circumference of the impeller unit, thereby inhaling air of outside while the centrifugal impeller rotates when the rotary shaft rotates. |
