According to the air flow control device, the air flow flowing along the grating and penetrating through the grating sequentially passes through the large-aperture air holes and the small-aperture air holes, so that the air resistance passing through the grating can be adjusted, the large air volume passing through part of the grating is avoided, and the air flow passing through each part of the grating is relatively uniform; thereby make the air current through the evaporimeter comparatively even, the heat transfer is effectual.
In some embodiments, the grille is provided with three different aperture wind holes along said first direction.
In the flowing direction of the air flow, three air holes with different hole diameters, such as the first air hole 41, the second air hole 42 and the third air hole 43, are usually arranged on the grille, so that the effect of well homogenizing the air flow can be achieved.
In some embodiments, the flow area of the airflow is tapered as the airflow passes through the first and second air holes 41 and 42 in sequence along the first direction.
When the airflow sequentially passes through the first air holes 41 and the second air holes 42 along the first direction, the flow area of the airflow is gradually reduced, so that the larger the amount of wind accumulated at the second air holes 42 is, the larger the wind resistance is, the airflow is promoted to pass through the grille at the positions of the first air holes 41, and the airflow passing through all parts of the grille is relatively uniform.
In some embodiments, the grid comprises at least two layers in the thickness direction: a first grid plate and a second grid plate.
The hole distribution modes of the two layers of grids can be the same or different, and the first grid plate and the second grid plate can be arranged in a relatively staggered moving mode, so that the aperture of the through hole can be adjusted.
In some embodiments, the grille assembly further comprises a driving member capable of driving the first grille plate and the second grille plate to move relatively.
