According to the embodiment, various structural proportions among the vertical shaft, the horn mouth, the heat collecting surface and the building are obtained according to practice, and the structural proportions can achieve a better ventilation effect.

In this embodiment, the shaft and the bell mouth are made of reinforced concrete material, and are built together when a building is built. The heat collecting plate is made of heat collecting materials and can collect heat in the shaft. The heat collecting plate is formed by splicing a plurality of glass plates with heat collecting function or other heat collecting plates, and the upper surface of each glass plate is coated with a heat insulating layer; the heat collecting plate is of a structure with a high middle and a low edge, and the gradient between the middle position and the edge position of the heat collecting plate is 3%. The area of the heat collecting plate is large, so that the glass plates are spliced and installed for convenient installation, the 3% gradient of the heat collecting plate plays a role in removing rainwater, and the heat insulating layer on the heat collecting plate is convenient for isolating external heat. The heat collecting plates of the embodiment can be formed by splicing glass plates or other heat collecting plates, and a plurality of heat collecting materials of the heat collecting plates can be selected according to the ventilation quantity and the manufacturing cost required by a building.
