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.
Description
- The present invention relates to building equipment and, more particularly, to a building heat dissipation hood structure receiving a fan therein and a method for producing the building heat dissipation hood structure.
- To effectively expel or dissipate hot air in buildings, some of the buildings includes a ventilation through-hole in a top portion thereof, and a heat dissipation hood is mounted outside of a hole edge of the ventilation through-hole. The interior of the heat dissipation hood intercommunicates with the ventilation through-hole, and a vent is disposed in the top of the heat dissipation hood, such that the hot air can be guided to the outside. Furthermore, the heat dissipation hood includes guiding boards or baffles to prevent rainwater from falling into the interior of the building via the vent and the ventilation through-hole.
- In the above conventional structure, Applicant of the present invention has conceived of a fan mounted in the heat dissipation hood to accelerate the expelling speed. Although it is not difficult to install the fan in the heat dissipation hood, the actual effect is limited. Specifically, during a suction procedure in which the fan sucks hot air in the building, a so-called “cycle negative pressure” is apt to be created if the fan sucks air from another source. After the cycle negative pressure has been created, the fan will suck the air from another source at a near end thereof. As a result, the hot air that needs to be expelled out of the building cannot be sucked out.
- In view of the above, a leakage preventing mechanism must be sealingly disposed between the fan and the ventilation through-hole to avoid leakage. In a case that the fan is firstly mounted in the heat dissipation hood which is then mounted to the hole edge of the ventilation through-hole, the leakage preventing mechanism cannot be sealingly disposed between the fan and the ventilation through-hole, because the fan has already been installed in the heat dissipation hood.
- In another approach, the fan is firstly mounted to the top portion from inside of the building, which requires construction of a high shelf inside the building and subsequent installation of the fan in the midair, involving high risks of work.
- In a first aspect, a method for providing a building heat dissipation hood structure includes forming a ventilation through-hole in a top portion of a building; disposing a heat dissipation hood in the top portion of the building, with the heat dissipation hood located corresponding to the ventilation through-hole; and mounting a fan 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 top portion of the building. A leakage preventing mechanism is disposed in an intersection area between the fan and the hole edge of the ventilation through-hole. The heat dissipation hood is then installed in the top portion of the building.
- In a second aspect, a building heat dissipation hood structure according to the present invention includes a ventilation through-hole disposed in a top portion of a building. A heat dissipation hood is mounted on the top portion of the building and is located corresponding to the ventilation through-hole. 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 top portion of the building. A leakage preventing mechanism is disposed in an intersection area between the fan and the hole edge of the ventilation through-hole. Then, the heat dissipation hood is mounted on the top portion of the building.
- Since the installation starts from superimposing the fan on the top side of the hole edge from the top portion of the building, a worker can proceed with the installation on the top portion of the building, which is relatively safe. Furthermore, since the fan is superimposed on the hole edge from the top portion of the building, installation of the fan independent from installation of the heat dissipation hood is permitted, and such an arrangement is helpful in disposition of the leakage preventing mechanism in the intersection area between the fan and the hole edge of the ventilation through-hole. This avoids creation of the cycle negative pressure resulting from suction of air from another source (such as the air in the heat dissipation hood). Accordingly, the fan can simply suck the hot air in the building.
- The present invention will become clearer in light of the following detailed description of an illustrative embodiment of this invention described in connection with the drawings.
-
FIG. 1 is a perspective view of a top portion of a building and a fan according to the present invention. -
FIG. 2 is a perspective view of the top portion of the building and the fan after assembly. -
FIG. 3 is an exploded, perspective view of a heat dissipation hood and the assembly ofFIG. 2 , forming a heat dissipation hood structure according to the present invention. -
FIG. 4 is a cross sectional view of the heat dissipation hood structure ofFIG. 3 . - With reference to
FIGS. 1-4 , a building heat dissipation hood structure receiving a fan therein according to the present invention includes a ventilation through-hole 11 disposed in atop portion 1 of a building. Aheat dissipation hood 2 is mounted on thetop portion 1 of the building and is located corresponding to the ventilation through-hole 11. Afan 3 is mounted in theheat dissipation hood 2. - With reference to
FIGS. 1 and 2 , in installation, a periphery of thefan 3 is firstly superimposed on a top side of a hole edge of the ventilation through-hole 11 from thetop portion 1 of the building. Furthermore, aleakage preventing mechanism 4 is disposed in an intersection area between thefan 3 and the hole edge of the ventilation through-hole 11. Then, theheat dissipation hood 2 is installed in thetop portion 1 of the building. - Specifically, a method for providing a building heat dissipation hood structure according to the present invention includes forming a ventilation through-
hole 11 in a top portion of a building; disposing aheat dissipation hood 2 in thetop portion 1 of the building, with theheat dissipation hood 2 located corresponding to the ventilation through-hole 11; and mounting afan 3 in theheat dissipation hood 2. A periphery of thefan 3 is firstly superimposed on a top side of a hole edge of the ventilation through-hole 11 from thetop portion 1 of the building. Aleakage preventing mechanism 4 is disposed in an intersection area between thefan 3 and the hole edge of the ventilation through-hole 11. Theheat dissipation hood 2 is then installed in thetop portion 1 of the building. - Since the installation starts from superimposing the
fan 3 on the hole edge from thetop portion 1 of the building, a worker can proceed with the installation on thetop portion 1 of the building, which is relatively safe. - Furthermore, since the
fan 3 is superimposed on the top side of the hole edge from thetop portion 1 of the building, installation of thefan 3 independent from installation of theheat dissipation hood 2 is permitted, and such an arrangement is helpful in disposition of theleakage preventing mechanism 4 in the intersection area between thefan 3 and thehole edge 11 of the ventilation through-hole 11. This avoids creation of the cycle negative pressure resulting from suction of air from another source (such as the air in the heat dissipation hood 2). Accordingly, thefan 3 can simply suck the hot air in the building during the suction procedure. - Although a specific embodiment has been illustrated and described, numerous modifications and variations are still possible without departing from the scope of the invention. The scope of the invention is limited by the accompanying claim.
