Abstract
PURPOSE: To increase the fan efficiency, by providing a plurality of projections on the side face of an impeller for producing air flow radially outwards by the rotation of the impeller, and thereby preventing reverse flow of air.
CONSTITUTION: On the side face of an impeller 16 having a plurality of blades 16a where it faces a casing 11 and a casing cover 13 with a small clearance, there are provided a plurality of projections 20 at the position not facing an air passage 12. Since, with such an arrangement, the projections 20 function as a centrifugal fan and produce wind in radially outward directions with rotation of the impeller 16, air drawn from an air inlet port 14 is compressed in the air passage 12 and almost all of the air is discharged to the outside from an outlet port 15, so that reverse flow of the air is not caused. Therefore, it is enabled to increase the fan efficiency regardless of the clearance between the impeller 16 and casings 11, 13 at which they face each other at the position excluding the area facing the air passage 12.
