PURPOSE:To improve the wind blowing performance by making the blade part of a blower fan with a shape memory alloy material and mounting a motor capable of normal and reverse rotation in the blower. CONSTITUTION:The blade 2 of a fan proper 1 is made of shape memory alloy material. It takes the shape of the continuous line at the time of low temperature and that of the broken line at the time of high temperature. Namely, its revolving functions can be put into full play in both directions. A motor 3 is capable of both normal and reverse rotation. It can direct blown air upward and downward depending on cooling or warming. Such being the case, it is possible to improve the vertical temperature distribution and ensure sufficient blowing performance.
