PROBLEM TO BE SOLVED: To provide a blade structure for increasing amount of sucked air current, and a heat radiator using it. SOLUTION: The blade structure has a shaft housing 10 and a plurality of moving blades 20 disposed to surround the shaft housing 10. The feature of the blade structure lies at the end of a suction port of the heat radiator, the plurality of moving blades 20 connected on the shaft housing 10 extend radially along the upward part of the shaft housing 10 toward the center position of the shaft housing 10. Thus, turbulence hardly occurs in the sucked air, and the amount of sucked air current increases. COPYRIGHT: (C)2004,JPO
