Abstract: The invention provides a flake and method for reducing waste heat using water produced when an air conditioner operates and thereby heat exchange efficiency can increase. Accordingly, an energy-saving effect can be achieved. The flake is placed at an inner bottom side of the air conditioner and between a condenser fan and a condenser coil. When the condenser fan operates, wind power created by the condenser fan has a portion blowing toward the flake, and then blowing toward underlying water, produced when the air conditioner operates, along the flake such that the water can move to the condenser coil and cool the condenser coil. Thereby, the temperature of discharged waste heat can be reduced. When the condenser coil cools, heat exchange efficiency increases. Accordingly, an indoor cooling effect can be improved and an energy-saving effect can be achieved.

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.

Abstract: The present invention provides an airflow outlet of air-conditioning device, which comprises a main body having one end forming an entrance opening and an opposite end forming a plurality of outward-projecting curved ridges. At least one of the curved ridges has a side wall forming at least one through hole to allow air to pass through the through hole. The present invention allows airflows generated by an air-conditioning device to be conducted to the through hole to be discharged therefrom. Since the through hole is formed in a side wall, airflows do not blow directly down as that occurring in the conventional devices and instead blowing sideways so as to eliminate any potential risk of causing discomfort of persons located under the airflow outlet.
