However, scientific and technological progress not only brings benefits but also negative damage. With the increasing global warming problem, people gradually began to pay attention to environmental protection issues, and there are many products for the purpose of environmental protection. 
     At present, the existing air conditioners all have energy saving features, but people do not pay attention to the issue of heat discharged from the air conditioners. The discharged heat from the air conditioner has a great impact on the environment, such as air pollution and thermal pollution. A large number of hot air discharged from air conditioners will form a heat island effect that city temperature is higher than the rural suburbs, so that people feel unbearable in the city. Further, the air conditioners are operated at high temperatures for a long time, resulting in low operating performance and life. Additionally, air conditioning can cause damage due to overheating.

     In the following detailed description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the disclosed embodiments. It will be apparent, however, that one or more embodiments may be practiced without these specific details. In other instances, well-known structures and devices are schematically shown in order to simplify the drawings.

The controller  47  is electrically connected to the condenser fan  41 , the evaporator fan  43  and the compressor  45 . One end of the condenser coil  42  is connected to the compressor  45 , and another end is connected to the expansion valve  46 . One end of the evaporator coil  44  is connected to the compressor  45 , and another end is connected to the expansion valve  46 . Generally speaking, the condenser fan  41  faces toward the condenser coil  42 , and the evaporator fan  43  faces toward the evaporator coil  44 . Therefore, FIG. is a stereoscopical perspective schematic view of each component of the air conditioner, but the present invention is not limited thereto. 
     Regarding to an arrangement of the flow guiding device according to the present invention, as shown in  FIG. 1 ,  FIG. 2  and  FIG. 3A-3B , the flow guiding device  1  is obliquely disposed between the condenser fan  41  and the condenser coil  42 , and the flow guiding device  1  has a top at level lower than an axis  49  of the condenser fan  41 . Therefore, the airflow generated by the operating condenser fan  41  is first blown through the flow guiding device  1  to the condenser coil  42 . 
     As shown in  FIG. 4-6 ,  FIG. 4-6  are the most embodiments of the gas guiding devices according to the present invention. Please refer to  FIG. 4 , the flow guiding device  1  comprises a flake body  10  and a plurality of flow guiding member  3 ; wherein the flake body  10  has a plurality of holes  14  disposed through the flake body  14  and a plurality of flow guiding protrusions  2 . The plurality of holes  14  are disposed through two opposite sides of the flake body  10 , the plurality of flow guiding protrusions which have spaces among them are disposed on two opposite sides of the flake body, and a space between two of the plurality of flow guiding protrusions  2  is defined as a concave  13 . A plurality of flow guiding member  3  are disposed on each of concaves  13  of the flake body  10 , and parts of the plurality of holes  14  on the two opposite sides  11  are connected to the plurality of the flow guiding member  3 . Namely, each of the hole  14  on the two opposite sides  11  is not totally connected to the flow guiding member  3 . 
     Please refer to  FIG. 4 , each of the flow guiding member  3  is a solid cylindrical  302 , or a hollow cylindrical  301 , or part is the solid cylindrical  302 , or part is the hollow cylindrical  301 ; wherein when the flow guiding member  3  is connected to the holes  14 , the hollow cylindrical  301  has a bottom surface  31  and a top surface  32 . The bottom surface  31  may be connected to the holes, and the top surface  32  may have different aspects, such as the top surface to be a planar or a zigzag surface shown in  FIG. 5 . If the flow guiding member  3  is the hollow cylindrical  301 , the airflow will be flowing more smoothly. However, the flow guiding member  3  is the solid cylindrical  302 , the airflow produces a separated flow, thereby forming a turbulent flow. The aforementioned solid or hollow cylindrical flow guiding member  3  can effectively enhance the flow velocity of the airflow, so that the foreign matter such as the water vapor W and the dust (not shown) inside the air conditioner  4  shown in  FIGS. 3A to 3B  is quickly brought out. 
     Furthermore, in order to accelerate the airflow passing through the gas guide member  3 , the plurality of concaves  13  on the gas guide member  3  have a gas hole  33  disposed through therefore. As shown in  FIG. 5 , the axle center Φ 2  of the gas hole  33  is disposed through the gas guide member  3 , namely, one axle center Φ 1  of the gas guide member  3  and the axle center Φ 2  of the gas hole  33  are perpendicular to each other. 
     The flow guiding protrusions  2  of this embodiment may be design as a plane  20  or a protrusion  21  in order to drive flow of the airflow; thereby increasing the velocity of the airflow and guiding the flow direction of the airflow. Specifically, the flow guiding protrusions  2  of  FIG. 4  and FIG. 5  are planes  20 , and the flow guiding protrusions  2  and the flake body  10  are formed an angle θ 1 ; wherein the angle is randomly varied between 0 and 180 degrees based on actual requirements. Regarding to the flow guiding protrusions  2  in the bottom of  FIG. 6 , the flow guiding protrusions  2  is disposed on the bottom of the air conditioner, and the protrusion  21  protrudes from the two opposite sides  11  to form a curved surface  211  on one side of the protrusion  21 . 
     A method for dissipating waste heat from an air conditioner is described according to combine the flow guiding device  1  and the air conditioner  4 . The internal parts configuration of the air conditioner has been described in detail above, so the description of the internal parts configuration of the air conditioner will be omitted here. 
     Please refer to  FIG. 3A  and  FIG. 3B , the flow guiding device  1  is obliquely configured between the condenser fan  41  and the condenser coil  42 , and the flow guiding device  1  has a top at a level lower than an axis of the condenser fan  41 ; wherein one side of the two opposite side  11  which faces the condenser fan  41  is a windward side F. Further, one side of the two opposite side  11  is the windward side and an angle θ is formed between the side  11  and the bottom  48 , and the leeward side of another side  11  faces the condenser coil  42 . When parts of the airflow operated in the condenser fan  41  moves toward the windward side F, parts of the flow passes through the flow guiding protrusion  2  and the flow guiding member  3  of the flow guiding device  1  drive the water vapor W on the bottom surface  48  to move toward the condenser coil  42  along a direction D of the blowing airflow. From above, we can see that the arrangement of the flow guiding device  1  may effectively guide and drives with the flow direction and velocity of the airflow. As the flow velocity of the airflow increases, the foreign objects, such as the water vapor W on the bottom surface  48  in the housing  40  and the dust (not shown) are brought out of the housing  40  of the air conditioner  4 . On the other hand, the water vapor W is used to lower the internal temperature of the air conditioner  4 . 
     Further,  FIG. 3A  is an aspect of the flow guiding device  1  obliquely configured, the windward side F of the side  11  and the bottom surface  48  of the air conditioner  4  are formed the angle θ which is less than 90 degrees. Therefore, the flow guiding device  1  will generate a larger wind pressure, and the relative airflow velocity will also be stronger. Therefore, the airflow may be forcibly pressed so that the airflow flow along the windward side F toward the bottom surface  48  of the air conditioner  4 . The water vapor W on the bottom surface  48  of the air conditioner  4  is taken up and the water vapor W brought out by the airflow is taken to the condenser coil  42  by means of the airflow blowing direction D formed by the condenser fan  41 . 
     On the other hand,  FIG. 3B  is another aspect of the title flow guiding device  1 . The flow guiding device  1  is obliquely configured in the other direction so that the windward side F of the side  11  and the bottom surface of the air conditioner  4  are formed an angle θ that is greater than 90 degrees. Therefore, the flow guiding device  1  will cause a small wind pressure and the relative flow velocity will be weakened. Furthermore, the flow velocity of the airflow may be regulated and the direction of airflow blowing D may be guided by the different angles of inclination. 
     The speed of airflow may be adjusted by changing the direction of inclination of the windward side F of the flow guiding device  1 . Therefore, the design of the flow guiding device  1  may be changed based on the different countries or regions. The shapes and the installation locations of the flow guiding device  1  are not limited to the drawings. 
     Furthermore,  FIG. 7  to  FIG. 15  are some embodiments of the present invention. The present invention provides a supplementary device for enhancing and accelerating heat dissipation of gas guiding device. As shown in  FIG. 7  to FIG. 8 , the supplementary device  5  is configured on the top of the flow guiding device  1 . 
     Please refer to  FIG. 9 , the supplementary device  5  comprises a flake body  50  and a plurality of air deflectors  51 . The plurality of air deflectors  51  are equidistantly disposed on one of one surface  501  of the flake body  50 , and the flake body  50  is a plane (not shown) or a curved surface  500 . Please refer to  FIG. 10  and  FIG. 11 , the interference of the airflow will have different effects depending on the difference in the placement direction of the supplementary device  5 . As shown in  FIG. 10 , when the air deflectors  51  faces the condenser fan  41 , airflow blocking effect can be achieved because of the air deflectors  51  to be the windward surface F. On the contrary, as shown in  FIG. 11 , when the air deflector  51  oppositely faces the condenser fan  41 , that is, the surface which is the windward surface F does not include the air deflectors  51  on the flake body  50 . The airflow passes along both sides of the flake body  50  along the windward surface F of the flake body  50  to fast flow to condenser coil  42 . 
     Further, please refer to  FIG. 12 ,  FIG. 12  is parts of side view of flow guiding device and the supplementary device configured in the air conditioner according to the present invention. The supplementary device  5  above the flow guiding device  1  is used to enhance and accelerate the movement of the water vapor W driven by the flow guiding device  1  to the condenser coil  42  in the wind blowing direction D. The structure and operation of the flow guiding device  1  have been described in detail in the foregoing embodiments, and details are not described herein again. 
     Additionally, please refer to  FIG. 13  to  FIG. 15 , as shown in  FIG. 13 , the air deflectors  51  may be formed in the shape of a semicylinder (a), a rod (b), a hollow tube (c), a solid columnar body (d). As shown in  FIG. 14 , the air deflectors  51  may also be various wavy shapes. As shown in  FIG. 15 , the air deflectors  51  may further form a predetermined distance between the air deflectors  51  so that the air deflectors  51  may be easily assembled with the flake body  50 . Please refer to  FIG. 9 , each of the air deflectors  51  may further include a hole  510  to allow the airflow to flow at a faster speed. The degree of airflow interference may vary according to different shapes of the hole  510 . 
     In summary, in order to solve the conventional air conditioner cannot be quickly cooled and emissions the water vapor. Therefore, the present invention provides a flow guiding device for an air conditioner and a supplementary device. The structure of the flow guiding protrusions on flake body of the flow guiding device and the configuration of the flow guiding member are used to force the pressure of the airflow of the condenser fan and the direction of the wind to be directed downward so that the water vapor and dust are effectively brought out from the air conditioner. Additionally, regardless of the flow guiding device or supplementary device, the design of the windward direction and inclination angle may be changed according to the different climate conditions of each country and region, so as to achieve the purpose of regulating the flow velocity of the airflow and make it more convenient to use flexibility.
