<p><P>PROBLEM TO BE SOLVED: To provide a cooling rotary fan in which a stopping blast fin of the cooling rotary fan does not disturb cooling air from another cooling rotary fan which redundantly operates and an electronic apparatus provided with the cooling rotary fan. <P>SOLUTION: The cooling rotary fan 1 comprises a frame 11, the blast fin 12 and a rotary shaft 13. A motor is mounted on the frame 11 via a support part 11a and the rotary shaft 13 is attached to the motor. The blast fins 12 are arranged around the rotary shaft 13. Each blast fin 12 is composed of shape memorable material, lie down toward a circumference direction of a rotary direction R of the rotary shaft 13 when the rotary shaft 13 stops, and erect radial direction outward of the rotary shaft 13 by centrifugal force of the blast fins 12 when the rotary shaft 13 rotates. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
