The local design of the appearance air inlet panel is shown in fig. 2, and comprises a main appearance surface and an air inlet area, which are distributed in a staggered manner in a grid form, and the effect of staggered network third dimension is achieved through the effect of an inner baffle.
A partial top view of a section of the appearance air intake panel is shown in figure 3, which comprises a main appearance face and an air intake area, and a wind guiding plate structure for shielding internal parts behind the main appearance face and the air intake area. Besides the design of the air guiding direction, the projection length of the baffle plate projected on the main appearance surface needs to exceed the length of the air inlet area by a certain distance, and the optimal distance is 3-5 mm.
The design method of the panel for air intake of the appearance surface of the invention mainly carries out method constraint on the air supply of the subareas of the panel, the air guide direction and the size design of the air guide plate, and the expected aim is to design the three-dimensional effect of the staggered grid of the appearance of the air intake panel and the maximum air intake angle and the maximum air intake quantity.
It should be noted that the design of the main appearance surface is not limited to the staggered grid, but may be other designs, such as a cloud, a circle, a diamond, and the like.
The segmentation of the appearance surface is not limited to 4 segments, but can be of other multi-segment designs, and the segmentation air inlet principle is met.
It should be noted that the directional design of the wind guiding blades at the back of different sectional panels is not necessarily completely as shown in fig. 1, and the internal structure is shielded while the air inlet angle and the air quantity are ensured.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention. The foregoing is merely a preferred embodiment of the present invention, and it should be noted that it will be apparent to those skilled in the art that modifications and variations can be made without departing from the technical principles of the present invention, and these modifications and variations should also be regarded as the scope of the invention.
