Building heat dissipation hood structure receiving a fan therein and its producing method

Abstract

The present invention provides a building heat dissipation hood structure receiving a fan therein and its producing method, mainly includes providing a ventilation through-hole in a building top portion, and a heat dissipation hood is mounted on the building top portion in a location corresponding to the ventilation through-hole. Furthermore, a fan is mounted in the heat dissipation hood. A periphery of the fan is firstly superimposed on a top side of a hole edge of the ventilation through-hole from the building top portion. Furthermore, construction is conducted at a gap area between the fan and the hole edge of the ventilation through-hole to form a gap leakage-preventing edge. Then, the heat dissipation hood is installed in the building top portion. This avoids creation of a cycle negative pressure resulting from suction of air from another source during the suction procedure of the fan, such that the suction procedure can simply suck the hot air in the building.
