Heat dissipation device

Abstract

The heat dissipation device is installed on a building's exterior wall for blocking and dissipating 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 heat dissipation device can also prevent rain from permeating into the building.

I claim: 
     
         1 . A heat dissipation device for installing on a building's exterior wall, comprising:
 a cuboid and hollow body with openings on a top side and a bottom side, respectively; and   a plurality of support elements positioned in the space inside the cuboid body, thereby partitioning the space into a plurality of heat dissipation channels, where the heat dissipation channels independently connect the top and bottom openings of the cuboid body.   
     
     
         2 . The heat dissipation device according to  claim 1 , wherein the cuboid body and the support elements are integrally formed. 
     
     
         3 . The heat dissipation device according to  claim 1 , wherein the heat dissipation device is made of a flexible material so that a number of heat dissipation devices can be pieced and rolled together. 
     
     
         4 . The heat dissipation device according to  claim 1 , wherein the cuboid body has one of a wave-like, a saw-tooth, and a honeycomb-like cross-section. 
     
     
         5 . The heat dissipation device according to  claim 1 , wherein 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.
