Abstract

PURPOSE: To promote a reduction of the shaft power required for the fan, by using a shape storage metal for the fan blade and changing a slope of the fan blade due to the air temperature.
CONSTITUTION: A fan blade 1 is constituted by a combined unit of a shape memory metal 2 and a spring material 3 and the both materials are fixed by screws 4. The shape memory metal 2, changing into a materinal phase construction at the high temperature side and a martensite construction at the low temperature side, comes to be in a shape with a large sloped angle for the rotational direction at a high temperature thus providing a more blow amount. At a low temperature, a small sloped angle, feeding a less blow amount, can promote a reduction of the shaft horse power.
