- 互いに対向配置されたハブ(12)及びシュラウド(13)の外周部間に羽根(14)を架設してなるファンロータ(11)と、該ハブ(12)のシュラウド(13)とは反対側に配設され、該ファンロータ(11)をハブ(12)の中心軸周りに回転駆動するためのファンモータ(15)とを備え、上記ハブ(12)には、該ファンモータ(15)を冷却した冷却風(Wa)を該ハブ(12)のファンモータ(15)と反対側へ導出するための冷却風導出孔(12c)が開口形成された遠心ファンであって、
上記ハブ(12)の上記ファンモータ(15)と反対側の面における上記冷却風導出孔(12c)のハブ回転方向後側の開口縁部に、該開口縁部からハブ回転方向前側へ延びるガイド片(25)が形成されており、
上記ガイド片(25)のハブ回転方向前側端部と冷却風導出孔(12c)のハブ回転方向前側の開口縁部との間が開放されていることを特徴とする遠心ファン。 - 請求項1記載の遠心ファンにおいて、
ガイド片(25)のハブ径方向内側端部と冷却風導出孔(12c)のハブ径方向内側の開口縁部との間が閉塞されている一方、ガイド片(25)のハブ径方向外側端部と冷却風導出孔(12c)のハブ径方向外側の開口縁部との間が開放されていることを特徴とする遠心ファン。 - 請求項2記載の遠心ファンにおいて、
ガイド片(25)は、冷却風導出孔(12c)のハブ径方向内側部分を覆っていることを特徴とする遠心ファン。 - 請求項2又は3記載の遠心ファンにおいて、
ハブ(12)の中心部に、ファンモータ(15)と反対側へ略円錐状に突出する突出部(12a)が形成されており、
冷却風導出孔(12c)は、上記ハブ(12)の突出部(12a)の円錐面に開口形成されていることを特徴とする遠心ファン。
