Based on the above conditions and as little view blocking as possible, the size of the louvers 2 and the distance between two adjacent louvers 2 can be reasonably designed to optimize the relationship between cost and sunshade effect. In the above-mentioned embodiments, the setting of each angle is calculated based on the solar altitude angle and the local latitude, and with the different seasons, the latitude of the direct sunlight is different, and the solar altitude angles in different latitude areas are also different, as shown in the figure As shown, as far as this hemisphere is concerned, winter is about two months between light snow→winter solstice→great cold. 20°16′, as shown by the arrow in Figure 3a, this period is the coldest time of the year in the northern latitudes. At this time, the direct sun angle θ ₁ is taken as an approximate value of 20°, and the external sunshade louver structure is installed The latitude of the installation site is β, and its solar altitude angle is γ ₁ =70°-β. In order to maximize the energy obtained indoors during this period, it is required that the most sunlight enters the room through the louvers, that is, the louvers 2 produce The shadow area is the smallest. As we all know, when the sheet structure is parallel to the light, the shadow is the smallest value. Therefore, in this embodiment, preferably, the angle α ₁ between each louver blade 2 and the horizon is ≥70°- β; the summer in the northern hemisphere is basically about two months from Xiaoman → Xiazhi → Dashu. During this period, the latitude of direct sunlight is from 20°16′N to 23°26′N to 20°16′N. As shown in the direction of the arrow in Figure 3b, this period of time is the hottest period of the year in the northern latitude region. At this time, the direct sunlight angle θ ₂ is taken as an approximate value of 20°, and the latitude of the location where the external sunshade shutter structure is installed is β , then its solar altitude angle is γ ₂ =110°-β. In order to minimize the heat gained in the room during this period, that is, the louvers 2 are required to be able to cover the sunlight irradiated from the gap above them, the upper and lower adjacent The angle α ₂ between the line between the highest point and the lowest point of the two hundred blades 2 and the horizon is ≤110°-β; of course, the angle α ₁ =70°-β, and the angle α ₂ =110°-β is Preferred embodiment of this embodiment.
