Abstract
【解決手段】一方の送風ファン25aの作動時、他方の送風ファン25bは休止する。送風ファン25aから送風ファン25bに向かって気流が生成される。気流はフィン27同士の間の流通路を通過する。このとき、流通路の入り口に塵埃37が徐々に堆積していく。その後、送風ファン25aの停止と同時に送風ファン25bの動作が開始される。反対に送風ファン25bから送風ファン25aに向かって気流が生成される。流通路内で気流は反転する。こういった気流は流通路の入り口から塵埃37を取り払う。こうして塵埃の堆積は確実に回避されることができる。しかも、防塵フィルタの設置は回避されることができる。流通路には常に十分な流量で気流が流入する。
