Abstract

The invention discloses a rectifying and noise-reducing air outlet pipe, which is assembled on the air outlet end of electrical equipment such as a blower and suction machine. The guide part includes a plurality of concave-convex bodies as grooves and / or ribs. The air outlet pipe of the present invention has a rectifying and noise-reducing structure, and a guide part is provided in the port wall of the air outlet pipe, through which the air flow can be differentially diverted, so that the wind energy rectifies the turbulent flow and eliminates the impact of the turbulent flow on the wind. The air outlet resistance of the air outlet pipe makes the air flow smooth and reduces the working noise; the guide part of the air outlet pipe has little resistance to the air flow, and can effectively reduce the velocity gradient at the air outlet and reduce the noise; the rectification of the air outlet pipe reduces the noise. The noise structure is simple and ingenious, which is convenient for production and processing.

Description

technical field

[0001] The invention relates to an air outlet pipe of electrical equipment, in particular to an air outlet pipe with a rectification and noise reduction structure, belonging to the technical field of F16L9 / 21 in the International Patent Classification Table. Background technique

[0002] The air outlet pipe is the part that leads out the airflow generated by the electrical equipment. Taking the blower and suction machine as an example, in the past, no ribs were added to the air outlet pipe of the blower and suction machine, or some regular grids were added to meet the requirements of "safety regulations" Ribs, this structure, when the air outlet pipe is short or the air flow at the outlet end is turbulent, the grid ribs will hinder the air flow in the air outlet pipe, resulting in a decrease in the air output of the air outlet pipe and easy With the problem of increased noise, it also increases the load on electrical equipment and increases energy consumption...
