Technical Examples

A multiblade fan includes a case having an air intake port and an air exhaust port, an impeller disposed in said case and having a plurality of blades rotatable about the center of said air intake port, and a noise silencer fin extending substantially parallel to the opening plane of said air intake port, the noise silencer fin being disposed near the tongue of said case. The noise silencer fin suppresses excessive pressure variations and flow speed fluctuations in the vicinity of the air intake port, thereby suppressing the generation of noise.
