The existing common rectification and blowing cooling device that blows from inside to outside uses a porous metal mesh rectification cylinder as a damping material. After the wind enters the rectification cylinder, it is directly blown out from all sides of the rectification cylinder, which cannot ensure a low wind speed unevenness rate. At the same time, because it passes through multiple layers of metal mesh from inside to outside, the damping coefficient is large, the structure is complex, and it is inconvenient to install and use, which limits the production capacity. In addition, the wire mesh is easy to deform and has a short service life, resulting in high production and maintenance costs. Summary of the invention
