The hollow frames 11 and the shutter 12 define a communication with the opening 10. Air chamber 14. Each hollow frame 11 has an upper ventilation groove 141 disposed at a side surface and communicating with the air chamber 14, and a bottom ventilation groove 142 adjacent to the bottom end and communicating with the outside, and the air chamber 14 and the upper ventilation groove 141 And the bottom ventilation groove 142 forms a heat conduction channel I for discharging hot air from the room to the outside, and the heat conduction channel I can discharge the hot air in the room to the outside to achieve the heat dissipation effect, and further, the heat conduction flow The track I is a path that exhibits a meandering curve, and it is possible to prevent rainwater dripping on the roof 1 from flowing into the air chamber 14 from the bottom ventilation groove 142, thereby preventing rainwater from entering.

Although the roof heat dissipating structure 100 can discharge the indoor hot air to the outside to dissipate heat, when a fire accident occurs and a large amount of smoke is emitted, the smoke is discharged to the outside along the heat-transfer channel I which is bent and bent. The effect is quite limited and there is still room for improvement.

Therefore, the object of the present invention is to provide a building ventilation device capable of improving the smoke exhausting effect.

Thus, the novel building ventilation device is adapted to be mounted on a wall of a building, the building ventilation device comprising a frame unit, at least one ventilation unit, and a ventilation unit.
