Abstract

본 발명은 중장비에 적용되어 엔진룸의 주요 소음원인 팬소음을 감소시키는 중장비의 소음 감소장치에 관한 것이다.The present invention relates to a noise reduction device for a heavy equipment which is applied to a heavy equipment and reduces fan noise which is a main noise of the engine room.

본 발명을 엔진룸의 일측에 설치된 팬(1)과 연통하며 그 말단부가 라디에터도어(21)로 지지되는 격자형의 그릴(22)로 외기와 연통되게 구성된 라디에터(2)에 있어서, 상기 라디에터(2)의 양측에 목부(31)가 좁고 몸체(32)가 상대적으로 넓은 공명기(3)가 그 목부(31)에서 연통되게 다수설치되어 있는 것으로, 중장비에 손쉽게 적용되는 구조를 제시하여 경제성이 높으면서도 소음의 감소효과가 좋은 장치를 제공하여 선진국의 엄격한 소음 규제하에서도 문제없이 중장비를 가동할 수 있도록 한 유용한 발명인 것이다.A radiator (2) having a grill (22) communicating with a fan (1) installed at one side of an engine room and whose distal end is supported by a radiator door (21) 2 in that the neck 31 is narrow and the body 32 has a relatively large resonator 3 communicating with the neck 31. The structure is easily applied to the heavy equipment, This is a useful invention that enables a heavy equipment to operate without problems even under the strict noise regulations of developed countries by providing a device with a good noise reduction effect.
