Abstract

The invention provides a flow guide and diffusion integrated axial flow fan mesh enclosure which is mounted on a fan and comprises a flow guide cover body, the flow guide cover body is of a hollow structure, n flow guide blades are diverged in the flow guide cover body in the direction of the inner wall with the axis as the center, and a diffusion opening is formed in the end face deviating from the mounting direction. The simple safety protection function is achieved, and the functions of optimizing the fan performance, improving the fan efficiency and reducing noise are achieved.

Description

technical field [0001] The invention relates to the field of axial flow fan components, in particular to an axial flow fan net cover with flow guide and diffuser integrated. Background technique [0002] The grille is a component of the fan, and most of them only play a protective role and do not have a substantial impact on the performance of the fan. In the working process of the fan, the airflow leaving the fan blade has a spiral speed, corresponding to the fixed kinetic energy of the airflow spiral, in order to improve the static pressure and efficiency of the fan, it is necessary to install a shroud behind the fan blade. [0003] In all walks of life in our country, axial flow fan ventilation equipment is an important part, but the noise generated during its operation has also caused serious harm to people's life and production. It can be seen from the measurement that the noise at the air outlet of the axial flow fan is the main part of the fan noise. By installing a ...
