The shielding plate 2 and the wall plate 1 have a predetermined distance therebetween to form a sandwich gap 21, and the air flow in the sandwich gap 21 can flow to form a convection capable of taking away the heat transferred to the sandwich gap 21, wherein the outer surface of the shielding plate 2 is coated with a transmitting thermal insulating coating to reduce the heat transferred to the accommodating space 11.
In the present application, a hollow interlayer gap 21 is formed between the wall plate 1 and the shielding plate 2, and the gap distance of the hollow interlayer gap 21 is 10mm to 30 mm. In an embodiment of the present application, the thickness of the hollow gap 21 is set to 20 mm.
When the solar thermal radiation is absorbed from the outside 22 to the outside, a part of it remains on the outermost interlayer, another part continues to be radiated by the air to the inside of the interlayer, another part is carried out by the wind flowing through the interlayer channels, and the rest is radiated by the air to the next layer (casing). At this point, the remaining heat has been reduced by a fraction. By this method, part of the solar radiation is reduced.
