Claims (5)

  1. 각종 팬의 소음저감장치에 있어서, 집적회로를 구비하고 박막형의 실리콘 가공필름으로 제조되는 극소형전기기계장치를 날개의 소정부위에 하나 이상 설치하여 비선형 불안정모드가 증폭되지 않도록 하므로 난류에 의한 에너지 증폭을 방지하고 이산소음, 소역밴드소음과 광역밴드소음을 감소시키도록 구성시킨 소음저감장치.
  2. 제1항에 있어서, 소음저감장치가 각종 팬 날개의 소정부위에 설치되어 압력 및 풍속변동에 따른 난류유동을 검출하는 센서부; 센서부로부터의 신호를 분석하여 난류유동에 반하는 신호를 발생시키는 연산처리부와; 연산처리부로부터의 신호에 근거하여 진동하는 진동액츄에이터들을 일체식의 박막구조로 이루어지게 한 소음저감장치.
  3. 제1항에 있어서, 극소형 전기기계장치가 진동액츄에이터로 구성되게 한 소음저감장치.
  4. 제1항에 있어서, 극소셩 전기기계장치 대신 소정 무게를 가진 소정수의 돌기가 날개주위에 배열되도록 하여 날개주위에서 발생되는 유동을 제어하는 소음저감장치.
  5. 제1항에 있어서, 극소형 전기기계장치가 열교환기에 팬날개의 소정부위에 설치되어 날개의 불안정모드를 증폭하므로 에너지전달을 촉진하도록 한 소음저감장치.
