[0039] Example 1

[0040] like Figures 3-6As shown, the condenser includes a condenser body 5, which comprises a frame serving as the skeleton of the condenser body 5. Multiple heat dissipation fins are evenly arranged and fixed inside the frame. A copper heat dissipation tube is bent and passes through the multiple heat dissipation fins. High-temperature, high-pressure refrigerant gas is introduced into one end of the copper heat dissipation tube, and air-cooled heat exchange occurs through the heat dissipation fins at the bend. A cleaning component 8 includes a brush 87, which can roll and clean dust from the gaps between the heat dissipation fins. The frame forms the skeleton of the condenser body 5, and the bent copper heat dissipation tube passes through the multiple heat dissipation fins. Because the copper heat dissipation tube is bent inside the frame, the area of ​​the copper heat dissipation tube and the heat dissipation fins is increased, improving the heat exchange between the refrigerant and air inside the copper heat dissipation tube. The cleaning component 8 includes a square frame component, which is detachably installed on one side of the frame. Multiple brushes 87 are fixedly mounted on the same roller 86, which rolls along the square frame component. The multiple brushes 87 are evenly fixed on the surface of the roller 86, allowing the roller 86 to move and brush the dust inside the gaps between the heat dissipation fins. The square frame component includes two frame plates 81, with racks 82 fixedly connected between the ends of the two frame plates 81. The frame plates 81 and the racks 82 form a square structure. The roller 86 has gears 85 fixedly connected to both ends, with the gears 85 meshing on the rack 82. A driving component is provided on the roller 86, which drives the roller 86 to move along the rack 82. As the roller 86 moves along the rack 82, the gears 85 at both ends of the roller 86 roll on the rack 82, causing the roller 86 to rotate. Simultaneously, the roller 86 translates along the gears 85 and rotates on its own axis, thus rotating the brush disc 87. This allows the brush disc 87 to clean the dust from the heat dissipation fins. The driving component includes a pull rope 89 and a rubber band 88. The rubber band 88 connects the roller 86 to a fixed reference point at both ends, and the pull rope 89 rolls on its own axis. One end of the shaft 86 passes through the lower frame plate 81. Pulling the pull rope 89 can pull the roller 86 downwards, causing the roller 86 to move along the rack 82. At the same time, the roller 86 stretches the elastic band 88. When the pull rope 89 is released, the elastic band 88 pulls the roller 86 back to its original position. A guide rod 83 is fixedly connected between the two frame plates 81. A slider 84 is slidably connected to the surface of the guide rod 83. The slider 84 and the roller 86 are rotatably connected. The cooperation between the guide rod 83 and the slider 84 ensures that the gear 85 at the end of the roller 86 always meshes with the rack 82. A collar 810 is rotatably fitted on the surface of the roller 86. The collar 810 is fixedly connected to the elastic band 88 and the pull rope 89.

[0041] Working principle: The frame forms the skeleton of the condenser body 5. The heat dissipation copper tubes are bent and pass through multiple heat dissipation fins. Because the copper tubes are bent inside the frame, the surface area of ​​the copper tubes and fins is increased, extending the heat exchange time between the refrigerant and air inside the copper tubes and thus improving heat dissipation. Brushes 87 roll between the fins, cleaning dust from their surface and further improving heat dissipation. Multiple brushes 87 are evenly fixed to the surface of the roller 86. As the roller 86 moves, it drives the brushes 87 to clean dust from the gaps between the fins. The roller 86 is driven by a drive mechanism. The roller 86 moves along the direction of the rack 82. At this time, the gears 85 at both ends of the roller 86 roll on the rack 82, thereby causing the roller 86 to rotate. At the same time, the roller 86 translates along the gears 85 and rotates on its own axis, thereby allowing the brush plate 87 to rotate. This allows the brush plate 87 to brush and clean the dust from the heat dissipation fins. Pulling the pull rope 89 causes the roller 86 to translate along the rack 82. At the same time, the roller 86 stretches the elastic band 88. When the pull rope 89 is released, the elastic band 88 pulls the roller 86 back to its original position. The cooperation of the guide rod 83 and the slider 84 ensures that the gear 85 at the end of the roller 86 is always engaged with the rack 82.

[0042] Example 2

[0043] like Figures 1-2As shown, the air-cooled heat pump unit also includes a frame 1. A water tank 9 and a compressor 10 are installed inside the frame 1. The compressor 10 is connected to a condenser body 5 via copper pipes and internal heat dissipation copper pipes. A filter 11 is connected to the other end of the condenser body 5, and an expansion valve 12 is connected to the other end of the filter 11. The expansion valve 12 is connected to the other end of the expansion valve 12, which is located inside the water tank 9. The other end of the evaporator is connected to the compressor 10 via copper pipes. Two guide pipes 2 are connected to the side of the water tank 9. The compressor 10 compresses the refrigerant into a high-temperature, high-pressure gas. This high-temperature, high-pressure gas enters the condenser body 5 via copper pipes. The heat dissipation fins on the surface of the heat dissipation copper pipes exchange heat with the refrigerant, converting it into a low-temperature, low-pressure liquid. The refrigerant liquid enters the filter 11 through the copper pipes. The filter 11 filters out impurities from the refrigerant liquid. The filtered refrigerant liquid is then diverted and dispersed into the evaporator via the expansion valve 12 (or capillary tube). The refrigerant inside the evaporator cools the water in the water tank 9. Finally, the refrigerant is drawn back into the compressor 10. The compression process is repeated to continuously cool the water inside the water tank 9. One guide pipe 2 inputs water into the water tank 9, while the other guide pipe 2 removes the cooled water from the water tank 9. The cooled water is then poured into a designated area for further cooling. The upper end of the frame 1 is covered with a top cover 3, and a fan duct 4 is mounted on the upper end of the top cover 3. The fan duct 4 connects the upper and lower sides of the top cover 3, and a fan is installed inside the fan duct 4. The top of the top cover 3 protrudes upward near the perimeter, forming a recessed structure in the middle. An opening is provided in the recessed position of the top cover 3. The top cover 3 has a downward-recessed top end with a water spray hole 7 to collect rainwater. The rainwater sprays onto the inclined condenser body 5 along the water spray hole 7, thereby cleaning the dust on the heat dissipation fins of the condenser body 5. The fan inside the air duct 4 blows the air from the top end of the top cover 3 onto the condenser body 5, thereby accelerating the heat dissipation of the condenser body. The top cover 3 is located in the middle of the partition 6, and the top end of the top cover 3 has a downward-sloping slope on both sides starting from the partition 6. The slope can drain rainwater as much as possible.

[0044] Working principle: Compressor 10 compresses the refrigerant into a high-temperature, high-pressure gas. This gas travels along copper pipes into the condenser body 5 via heat dissipation copper pipes. The heat dissipation fins on the surface of the copper pipes exchange heat with the refrigerant, converting it into a low-temperature, low-pressure liquid. The liquid refrigerant then passes through copper pipes into filter 11, which removes impurities. The filtered liquid refrigerant then passes through expansion valve 12 (or capillary tube) and is diverted into the evaporator. Inside the evaporator, the refrigerant cools the water in water tank 9. Finally, the refrigerant is drawn back into compressor 10 and compressed again, and the above steps are repeated continuously. The water inside the water tank 9 is cooled by one guide pipe 2 into the water tank 9 and another guide pipe 2 to remove the cooled water from the water tank 9. The cooled water is poured into a designated area for cooling. The top cover 3 is recessed downward to collect rainwater. The rainwater is sprayed along the water holes 7 onto the inclined condenser body 5, thereby cleaning the dust on the heat dissipation fins of the condenser body 5. The fan inside the air duct 4 blows the air from the top cover 3 onto the condenser body 5, thereby accelerating the heat dissipation of the condenser body. The inclined slope can drain as much rainwater as possible.
