Abstract: A ventilation denoising device that includes at least one ventilation module disposed with at least two air ducts inside, the air ducts are communicated end-to-end to form a circuitous air duct. The ventilation module is provided with a first ventilation opening communicated with one end of the air duct, and a second ventilation opening communicated with the other end of the air duct. Also disclosed is a ventilation denoising system equipped with the above mentioned ventilation denoising device. The ventilation denoising device can be installed outside equipments, such as a machine cabinet, as ventilation means thereof, and also reduce the noise generated during the equipment operation.
