Description

TECHNICAL FIELD OF THE INVENTION

The present invention is generally related to heat dissipation devices, and more particular to a heat dissipation device installed on a building's exterior wall.

DESCRIPTION OF THE PRIOR ART

High rise buildings are common for accommodating the ever increasing urban population in the limited city space. These tall buildings are crowded together and as such lead to poor ventilation. The heat absorbed by the buildings therefore is trapped and cannot be dissipated easily.

To overcome this problem, the present inventor provides a reasonably designed and effective solution as outlined in the following.

SUMMARY OF THE INVENTION

A major objective of the present invention is to provide a heat dissipation device for installing on the exterior wall of a building. The heat dissipation device is capable of conducting the heat energy or blocking out the heat energy from sun. The heat dissipation device contains a cuboid body, a number of support elements. The cuboid body is hollow with openings on a top side and a bottom side, respectively. The support elements are positioned in the space inside the cuboid body, thereby partitioning the space into a number of heat dissipation channels. The heat dissipation channels independently connect the top and bottom openings of the cuboid body. A number of the heat dissipation devices can be installed on the outer surface of a building's exterior wall. Through the heat convection provided by the heat dissipation devices, the heat energy produced by sun is dissipated and the building's exterior wall is cooled down. The temperature inside the building is therefore prevented from rising too high.

Preferably, the cuboid body and the support elements are integrally formed.

Preferably, the heat dissipation device is made of a flexible material so that a number of heat dissipation devices can be pieced and rolled together.

Preferably, the cuboid body has one of a wave-like, a saw-tooth, and a honeycomb-like cross-section.

Preferably, the heat dissipation device has a side coated with an attachment layer for attaching the heat dissipation device directly to a building's exterior wall.

The present invention has the following effects.

Firstly, the heat dissipation device can be directly and conveniently installed on a building's exterior wall. Through heat conduction and convection, the exterior wall is cooled down and the temperature inside the building is reduced.

Secondly, there is no need to install additional and other heat dissipation apparatus for cooling down the building's exterior wall.

Thirdly, the heat dissipation device is able to protect a building's exterior wall from rain. Some old building's rain leakage problem can be resolved as well.

The function and effect of the present invention are described as follow. By having guiding ditches on the airflow guiding member and having the airflow guiding member detachably configured on the body, the manufacturing and assembly of the heat dissipation device is simplified. The higher cost due to the difficulty in working out guiding holes on extruded heat dissipation devices is as such avoided. Additionally, as the width of the guiding ditch is gradually reduced from the receiving section, through the regulating section, and to the guiding section, the airflow uniformly flows out of the body with an increased speed to form a planar air wall to confine pollutants in the air.

The foregoing objectives and summary provide only a brief introduction to the present invention. To fully appreciate these and other objects of the present invention as well as the invention itself, all of which will become apparent to those skilled in the art, the following detailed description of the invention and the claims should be read in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The following descriptions are exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims.

As illustrated in FIGS. 1 and 2, a heat dissipation device 1 according to a first embodiment of the present invention contains a cuboid body 10, a number of support elements 11, and a number of heat dissipation channels 12. The cuboid body 10 is hollow with openings 101 on a top side and a bottom side, respectively. The support elements 11 are positioned in the space inside the cuboid body 10, thereby partitioning the space into the heat dissipation channels 12. In other words, the heat dissipation channels 12 are separated by the support elements 11, and independently connect the top and bottom openings 101 of the cuboid body 10. In alternative embodiments, the cuboid body 10 can be shaped like a thin plate, and the support elements 11 can be integrally formed with the cuboid body 10.

A number of the heat dissipation devices 1 can be pieced laterally together to form a large planar structure, and the planar structure can be installed on the outer surface of a building's exterior wall 20 (as shown in FIG. 6).

As shown in FIG. 2, through the heat convection provided by the heat dissipation devices 1, the building can be cooled down. More specifically, a number of heat dissipation devices 1 can be vertically stacked together through a connection mechanism or waterproof adhesive so that their individual heat dissipation channels 12 are cascaded into a number of heat dissipation channels that run along the outer surface of the exterior wall from the bottom to the top of the building. When there is an imbalance of temperature distribution along the outer surface of the building's exterior wall, heat convection would occur where hat air would rise upward along with the heat energy of the various levels of the building, and cool air would be drawn into the cascaded heat dissipation channels 12, thereby achieving a reduction of temperature along the building's exterior wall.

Preferably, a heat conduction layer (not shown) could be coated along the outer surface of the building's exterior wall before attaching the heat dissipation devices 1 to further effectively remove the heat energy of the building. The heat conduction layer can be made of a metallic material or of a thermally conductive adhesive. Moreover, the heat dissipation devices 1 or the support elements 11 could be made of a highly thermally conductive material such as a metallic material so that the exterior wall of the building can be cooled down through not only heat convection but also heat conduction. Additionally, as the building's exterior wall is covered by the heat dissipation devices 1 and therefore is protected from rain, the present invention provides a waterproof side effect.

As shown in FIGS. 3 to 5, various types of heat dissipation channels 12 can be formed by appropriately configuring the support elements 11. For example, in FIG. 3, the support elements 11 are arranged to produce a saw-tooth cross-section in the cuboid body 10. In FIGS. 4 and 5, the support elements 11 are arranged to produce wave-like and tubular-channel cross-sections, respectively. Of course, it is also possible to achieve honeycomb-like cross-section. What are depicts are only exemplary and are not intended to limit the present invention.

The installation of the heat dissipation devices 1 can also be modified as required. For example, each heat dissipation device 1 can have a side coated with an attachment layer made of waterproof silicone or thermally conductive adhesive so as to attach the heat dissipation device 1 directly to the exterior wall 20 of the building.

As shown in FIG. 6, the heat dissipation devices 1 can be prepared into a roll of planar structure in advance. Together with the attachment layer, the heat dissipation devices 1 can be quickly attached to the exterior wall 20 of the building. In other words, the heat dissipation devices 1 can be made of a flexible material so as to be rolled together for convenient transportation, storage, and installation.

Exhaust fans can be further installed to the top ends of the heat dissipation channels 12 so as to draw the air inside the heat dissipation channels 12 for better heat dissipation efficiency.

While certain novel features of this invention have been shown and described and are pointed out in the annexed claim, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the spirit of the present invention.
