Abstract

AN IMPELLER OF A FAN INCLUDES HUB (3) MOUNTED WITH PLURAL BLADES (2). THE FAN BLOW AIR BY SPINNING THE BLADES. A REVOLUTION LOCUS OF A LEADING EDGE (6) OF BLADE (2) SHOWS A VALLEY IN A PORTION BETWEEN AROUND A CENTER AND TIP (8) OF BLADE (2), AND SHOWS A VALLEY IN A PORTION BETWEEN THE CENTER AND HUB (3), WITH REGARD TO WINDWARD. A CROSS SECTIONAL VIEW OF BLADE (2) IN A RADIAL DIRECTION SHOWS A VALLEY IN A PORTION BETWEEN AROUND A CENTER AND TIP (8), AND SHOWS A PEAK IN A PORTION BETWEEN AROUND THE CENTER OF BLADE (2) AND HUB (3). THIS STRUCTURE REALIZES TO LOWER A NOISE LEVEL AND INCREASE A STATIC PRESSURE. (FIGURE 1)
