Building heat dissipation hood structure receiving a fan therein and a method for producing the same

Abstract

A building heat dissipation hood structure includes a ventilation through-hole ( 11 ) disposed in a top portion ( 1 ) of a building. A heat dissipation hood ( 2 ) is mounted on the top portion ( 1 ) of the building and is located corresponding to the ventilation through-hole ( 11 ). A fan ( 3 ) is mounted in the heat dissipation hood ( 2 ). In a method for producing the building heat dissipation hood structure, a periphery of the fan ( 3 ) is firstly superimposed on a top side of a hole edge of the ventilation through-hole ( 11 ) from the top portion ( 1 ) of the building. A leakage preventing mechanism ( 4 ) is disposed in an intersection area between the fan ( 3 ) and the hole edge of the ventilation through-hole ( 11 ). The heat dissipation hood ( 2 ) is then installed in the top portion ( 1 ) of the building.

What is claimed is: 
     
         1 . A method for providing a building heat dissipation hood structure, comprising: forming a ventilation through-hole ( 11 ) in a top portion of a building; disposing a heat dissipation hood ( 2 ) in the top portion ( 1 ) of the building, with the heat dissipation hood ( 2 ) located corresponding to the ventilation through-hole ( 11 ); and mounting a fan ( 3 ) in the heat dissipation hood ( 2 ), wherein a periphery of the fan ( 3 ) is firstly superimposed on a top side of a hole edge of the ventilation through-hole ( 11 ) from the top portion ( 1 ) of the building, wherein a leakage preventing mechanism ( 4 ) is disposed in an intersection area between the fan ( 3 ) and the hole edge of the ventilation through-hole ( 11 ), and the heat dissipation hood ( 2 ) is then installed in the top portion ( 1 ) of the building. 
     
     
         2 .
