Embodiment 1

[0019] Embodiment one: see attached figure 1 And attached figure 2 shown.

[0020] A noise reduction cabinet includes a top cover 1, and two air ducts 2 are arranged on the top cover 1.

[0021] The air duct 2 includes an air outlet 3 arranged on the top cover 1 and connecting the inside and outside of the noise reduction cabinet, and an air duct 4 arranged inside the top cover 1 . The air duct 4 has a first end 5 and a second end 6, the first end 5 of the air duct 4 communicates with the tuyere 3, and the second end 6 of the air duct 4 is closed. The length direction of the air duct 4 is perpendicular to the air circulation direction in the tuyere 3 . The cross-section of the air duct 4 is rectangular, and the wall of the air duct 4 is provided with a plurality of through holes 7 whose axes are perpendicular to the length direction of the air duct 4 and whose cross-section is circular.

[0022] The air outlets 3 of the two air ducts 2 are arranged in parallel, ...

Abstract

The invention relates to a noise-reduction cabinet, comprising a top cover, wherein an air passage is arranged on the top cover; the air passage comprises a blast tuyere and an air pipe; the blast tuyere is arranged on the top cover and communicates the inside and the outside of the noise-reduction cabinet; the air pipe is arranged in the top cover; the air pipe is provided with a first end and asecond end; the first end of the air pipe is communicated with the blast tuyere; and a plurality of through holes are arranged on the wall of the air pipe. As the noise-reduction cabinet is provided with bent air passage, the airflow is damped when passing by the air passage; therefore, the speed of the airflow is reduced, thereby the noise of the cabinet can be reduced.

Description

technical field [0001] The invention relates to a noise reduction cabinet. Background technique [0002] In the prior art, electronic equipment is usually installed in a cabinet. In order to dissipate the generated heat, a fan is usually installed in the cabinet and an air inlet and an air outlet are provided on the cabinet. However, when the fan is working, the wind flows in the cabinet at high speed, which will cause huge noise. Contents of the invention [0003] The object of the present invention is to provide a cabinet capable of reducing wind velocity and noise. [0004] In order to achieve the above object, the technical scheme adopted in the present invention is: [0005] A noise reduction cabinet, comprising a top cover, the top cover is provided with an air duct, and the air duct includes an air port provided on the top cover and communicating with the inside and outside of the noise reduction cabinet, The air duct arranged inside the top cover, the air duct h...
