Abstract: Disclosed is a natural ventilation device for an upper part of a building, mainly including: an upper inclined plane air charging and discharging system, a lateral top plane air discharging system, and a top plane air discharging system. The upper inclined plane air discharging system is installed at an outer side of a top lateral air discharging port of a roof and is mainly provided with external cover bodies at two sides respectively. Top ends of two external cover bodies are respectively connected to a reflexed baffle installed downwards. An air outlet is enclosedly formed between two reflexed baffles. Several rain baffles are disposed between the two reflexed baffles, and a lower end of the rain baffle arranged in the central downwardly extends to form a deflector. A lower end of the deflector is respectively provided with a receiving groove portion. The interior of the receiving groove portion is provided with several splashing baffles; and a bottom end of the receiving groove portion is provided with lateral water discharging holes at two side surfaces of the upper inclined plane air discharging system. Moreover, the lateral top plane air discharging system is installed at an outer side of an upper part lateral air discharging port. A front end of the cover body is provided with an air outlet, and a central position inside the air outlet is inwards provided with a longitudinal external baffle. The interior of the external baffle is connected to a longitudinal internal baffle. Positions of the air outlets at two sides of the external baffle are respectively provided with several rain baffles. An upper and a lower ends of the upper part lateral air discharging port are respectively provided with an inclined guide plate, and a bottom of the cover body is provided with a water discharging hole. In addition, the top plane air discharging system is mounted on a top plane of a building by using the lateral top plane air discharging system and is constituted by additionally mounting a rear cover body and air deflector members at a front and a rear. Wherein, the rear cover body is mounted above the top air discharging port and is connected to the air inlet of the lateral top plane air discharging system, and the air deflector members are connected at an outer side of the air outlet of the lateral top plane air discharging system. Moreover, when the air deflector member structure is removed from the top plane air discharging system, the structure use of the top plane air discharging system can be changed to be the upper inclined plane air charging system. The natural ventilation device for the upper part of the building in the present invention is characterized in that each air charging and discharging system is provided with the several rain baffles and the water receiving structure at a lower end thereof so as to provide a good air discharging effect and effectively isolate the infiltration of external rain water. The top inclined air charging system is suitable for an introduction of airflow in a closed space of the top part of the building and acts in concert with the upper inclined plane air discharging system to discharge hot air, thereby having an effect of effectively circulating the air of the top part to lower an indoor temperature.
