Claims (3)

  1. 기계실(17)(36)(44)내에 배치된 콤프레서(18)(37)의 구동에 따라 발생하는 잡음을 없애는 냉각장치의 소음 장치에 있어서, 전술한 기계실은 방열용 열린구멍부(21a)(21b)(21c)(36a)(36b)(36c)(44a)(44b)(44c)(45a)를 갖는 폐쇄 공간으로 구성되고 기계실내의 3차원 방향의 각 치수 가운데 1방향의 치수를 다른 방향의 치수 보다 크게 설정함으로서 기계실내의 잡음의 정재파가 전술한 잡음의 제거대상으로 되는 주파수 지역이하에 있어서 1차 모드만 성립하도록 구성하고 또 전술한 방열용 열린 구멍부는 전술한 정재파의 성립방향에 대해 직교하는 방향으로 뻗은 얇고 긴 모양으로 형성되게 되고, 전술한 소음장치는 콤프레서의 구동에 동반해서 발생하는 음을 전기신호로 변환하는 수음기(22)(39)와 수음기에서의 출력신호를 가공하는 연산기와, 연산기에서 가공된 신호에 입각해서 동작하는 제어용 발음기(23)(40)(40')로 되어 전술한 기계실에서 외부로 방사되는 음을 능동적으로 제거하는 것을 특징으로 하는 냉각장치의 소음장치.
  2. 제1항에 있어서, 전술한 기계실은 냉각장치의 상부에 일체적으로 형성된 외피(32)로 둘러싸인 구획(33)을 1장 또는 복수장의 칸막이판(34)(41)(42)으로 분할한 것으로 형성되어 있는 것을 특징으로 하는 냉각장치의 소음장치.
  3. 제2항에 있어서, 전술한 방열용 열린 구멍부는 기계실의 상면에 형성되어 있는 것을 특징으로 하는 냉각장치의 소음 장치.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
