Claims (3)
- 油圧アクチュエータを作動させるための作動油が通るオイルクーラを含む複数の熱交換器を有する熱交換器ユニットと、
作動油の温度を検出する作動油温度センサと、
正転時に前記熱交換器ユニットに対して冷却風を供給する冷却ファンと、
前記冷却ファンを作動させる電気モータと、
前記電気モータを介して前記冷却ファンの作動を制御するコントローラと、
前記冷却ファンの正転作動時間をカウントするタイマーと、
加えられた手動操作に応じて前記冷却ファンを逆転させるための逆転信号を前記コントローラに出力する逆転信号出力スイッチとを備え、
前記コントローラは、前記タイマーによってカウントされた正転作動時間が第1所定時間に達した場合に前記冷却ファンを第2所定時間だけ逆転させると共に前記冷却ファンの逆転終了時に前記タイマーをリセットし、かつ、前記タイマーによってカウントされた正転作動時間が前記第1所定時間に達していない場合でも前記逆転信号出力スイッチから逆転信号が出力されたときには前記冷却ファンを前記第2所定時間だけ逆転させると共に前記冷却ファンの逆転終了時に前記タイマーをリセットし、
前記冷却ファンが逆転する条件として、前記作動油温度センサによって検出された作動油温度が閾値以下であることが含まれる建設機械。 - さらに、エアコンディショナ用冷媒を圧縮するコンプレッサと、前記コンプレッサによって圧縮された前記冷媒を凝縮するコンデンサとを備え、前記熱交換器ユニットは前記コンデンサを含み、
前記コントローラは前記冷却ファンを逆転させる際に前記コンプレッサの作動を停止させる、請求項1記載の建設機械。 - さらに、前記冷却ファンの正転時における前記熱交換器ユニットの上流側に配置されたフィルタを備える、請求項1または2記載の建設機械。
