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.

First claim

What is claimed is:

1. A ventilation denoising device, comprising:
at least one ventilating module that includes at least two air passages internal to the at least one ventilating module communicative end-to-end sequentially to form an air duct;
wherein the at least one ventilating module further includes a first ventilation opening and a second ventilation opening and a third ventilation opening, of which the first ventilation opening is communicative with an end of the air duct, and the second ventilation opening is communicative with another end of the air duct, and the third ventilation opening is disposed symmetrically with respect to the first ventilation opening and on an opposite side of the air duct from the first ventilation opening, and the third ventilation opening is communicative with the same end of the air duct as the first ventilation opening; wherein the first ventilation opening and the third ventilation opening of the at least one ventilating module are respectively configured to be communicative with air inlets of two symmetrically disposed equipments.

2. The ventilation denoising device according to claim 1 , wherein a number of the at least one ventilating modules is at least two, including an air inlet modular set and an air outlet modular set, wherein
a first ventilation opening of a ventilating module in the air inlet modular set and a first ventilation opening in the air outlet modular set are disposed at the same side of the equipment, and respectively communicative with ventilation openings provided at the same side on the equipment; and
a second ventilation opening of the ventilating module in the air inlet modular set is disposed at a first end of the ventilation denoising device, a second ventilation opening of the ventilating module in the air outlet modular set is disposed at a second end of the ventilation denoising device, and the second end of the ventilation denoising device is a different end from the first end of the ventilation denoising device.

3. The ventilation denoising device according to claim 1 , wherein two ends of the air duct are disposed at the same end of the at least one ventilating module.

4. The ventilation denoising device according to claim 1 , wherein the at least one ventilating module is a rectangular module having a cavity that includes a baffle plate for segmenting the cavity into the at least two air passages communicative end-to-end sequentially.

5. The ventilation denoising device according to claim 1 , further comprising:
a bracket for mounting the ventilation denoising device on an equipment;
wherein the at least one ventilating module is mounted on the bracket.

6. The ventilation denoising device according to claim 5 , wherein the ventilating module is detachably mounted on the bracket.

7. The ventilation denoising device according to claim 1 , wherein an air driving device is provided at the first ventilation opening of the at least one ventilating module.

8. The ventilation denoising device according to claim 1 , wherein a noise-reducing component is provided in the air duct of the at least one ventilating module.

9. A ventilation denoising system, comprising:
equipment to be ventilated and noise-reduced; and
a ventilation denoising device, comprising:
at least one ventilating module that includes at least two air passages internal to the at least one ventilating module communicative end-to-end sequentially to form an air duct;
wherein the at least one ventilating module includes a first ventilation opening and a second ventilation opening and a third ventilation opening, of which the first ventilation opening is communicative with an end of the air duct, and the second ventilation opening is communicative with another end of the air duct, and the third ventilation opening is disposed symmetrically with respect to the first ventilation opening and on an opposite side of the air duct from the first ventilation opening, and the third ventilation opening is communicative with the same end of the air duct as the first ventilation opening; and
wherein the equipment includes ventilation openings, wherein the ventilation denoising device is mounted external to the ventilation openings of the equipment, and wherein the first ventilation opening and the third ventilation opening of the at least one ventilating module are respectively communicative with air inlets of two symmetrically disposed equipments.

10. The ventilation denoising system according to claim 9 , wherein an air driving device is provided at the first ventilation opening of at least one ventilating module.

11. The ventilation denoising system according to claim 9 , wherein the ventilation denoising device is mounted at one side of the equipment.
