In addition, the positions of the external pipes and wires are often protected by simple sealing glue or plastic covers.

[0004] In the prior art, the problem is particularly prominent in subtropical and tropical regions where mosquitoes are highly prevalent. For example, in the South China region, the number of failure repairs caused by termite intrusion into the air conditioning circuit during the back-to-south period increased by 300%; in Southeast Asia, 35% of compressor failures are directly related to the entry of geckos causing fan jamming; in coastal cities in Africa, the failure rate of the frequency conversion module overheating protection increased by 40% due to the intrusion of sand flies into the heat dissipation system. After the intrusion of mosquitoes, a series of failures such as circuit short circuit, mechanical jamming and heat dissipation failure are caused, which seriously affects the service life of the unit and the user experience.

The shell 100 of the outdoor unit of the air conditioner is used as the core protection structure, mainly undertakes the multiple functions of protecting internal components, optimizing operating environment and improving energy efficiency.

[0063] In some embodiments, the air conditioner outdoor unit further comprises an outdoor heat exchanger arranged inside the shell 100. The air conditioner outdoor heat exchanger is the core component of the refrigeration cycle, mainly bearing the heat exchange and energy transfer function. It realizes efficient heat transfer between indoor and outdoor through the design of copper-aluminum composite finned tube structure and the principle of phase change of refrigerant, quickly releases condensation heat in cooling mode, and absorbs environmental heat in heating mode.

[0064] In some embodiments, the air conditioner outdoor unit further comprises an outdoor fan arranged inside the shell 100, which is used to drive air to enter the shell 100 through the outdoor air inlet, and the airflow contacts and exchanges heat with the outdoor heat exchanger and then is output through the outdoor air outlet. The air conditioner outdoor fan is the core power component for driving air circulation, which generates forced airflow by high-speed rotation of the axial flow impeller, pushes external air to be sucked into the shell 100 through the air inlet, and is efficiently discharged from the air outlet after completing heat exchange on the surface of the heat exchanger fins.

[0065] In some embodiments, the air conditioner outdoor unit further comprises a heat dissipation port 200 arranged on the shell 100. The heat dissipation port 200 of the air conditioner outdoor unit is the key channel for heat dissipation, and its structure design directly affects the heat dissipation efficiency of the whole machine.

[0066] In some embodiments, the air conditioner outdoor unit further comprises a filter screen 300 arranged on the inner side of the shell 100 and covering the heat dissipation port 200. The filter screen 300 prevents mosquitoes from entering and causing circuit failure, fan jamming, and affecting the heat dissipation system. In addition, the filter screen 300 can effectively block dust, willow catkins and other impurities in the air from entering the inside of the shell 100, keep the heat exchanger fins clean, and avoid the decrease of heat dissipation efficiency caused by dust accumulation.

[0067] In some embodiments, the air conditioner outdoor unit further comprises an ultrasonic generator 400 arranged inside the shell 100, which is used to emit sound waves. The ultrasonic generator 400 drives away mosquitoes to prevent them from nesting or blocking and damaging the internal components of the air conditioner outdoor unit.

[0068] Through the above scheme, the filter screen 300 and the ultrasonic generator 400 are arranged to cover the heat dissipation port 200, the filter screen 300 can physically block mosquitoes from entering the inside of the shell 100, and the ultrasonic generator 400 emits sound waves of a specific frequency to interfere with the perception ability of mosquitoes or produce a driving effect, thereby reducing the possibility of mosquitoes approaching the heat dissipation port 200 from the source, achieving efficient mosquito prevention without affecting normal heat dissipation and ventilation functions. Especially, the ultrasonic generator 400 is arranged inside the shell 100, which has good mosquito repelling effect inside the shell 100, so even if mosquitoes enter, they will be driven away or killed by the ultrasonic generator 400.

[0069] In some embodiments, the minimum width of the heat dissipation hole 200 is not more than 3 mm. This size can ensure sufficient ventilation and effectively block most mosquitoes or crawling organisms from directly entering through the aperture, achieving the best balance between aerodynamics and insect prevention needs.

[0070] In some embodiments, the heat dissipation hole 200 has multiple heat dissipation holes arranged in a louver shape. The louver-shaped heat dissipation hole 200 of the air conditioner outdoor unit adopts a porous array design, forming a directional airflow channel through scientifically arranged guide vanes, which can improve the heat dissipation efficiency by 15%-20% and effectively block rainwater and foreign matter from entering.

[0071] In some embodiments, the heat dissipation hole 200 is long and narrow, with a width of not more than 3 mm. This can prevent larger insects from passing through the heat dissipation hole 200, achieving the first layer of insect prevention.

[0072] In some embodiments, the heat dissipation hole 200 can be rectangular.

[0073] In some embodiments, the heat dissipation hole 200 can be circular, with a diameter of not more than 3 mm.

[0074] In some embodiments, the mesh 300 has a mesh count of not less than 40 mesh. The mesh count of the mesh 300 represents the number of filter holes per square inch, so in the case of the same material, the higher the mesh count, the smaller the filter hole diameter. Therefore, the high-density mesh 300 used in this application can intercept small insects, significantly improving the filtering accuracy compared to conventional dust screens, and the mesh count has been experimentally verified to maximize the insect prevention effect within a controllable pressure loss range.

The 20-65 kHz wideband ultrasonic wave covers the sensitive frequency band of mosquitoes (e.g., mosquitoes are sensitive to 38 kHz-44 kHz), and is compatible with multiple types of pests such as cockroaches (20 kHz-60 kHz), avoiding the development of adaptability by pests through variable frequency pulse mode, and providing stronger pest prevention versatility than single frequency solutions.

[0078] In some embodiments, the ultrasonic generator 400 can be stably operated at any frequency in the range of 20 kHz to 65 kHz. In this case, the output of the ultrasonic generator 400 is stable, thereby improving the service life of the ultrasonic generator 400. When a certain area has a large number of a certain type of insects, a specific frequency can be selected according to the insects to achieve the insect repelling effect for the insects.

[0079] In some embodiments, the ultrasonic generator 400 changes the frequency at an interval, so that the emitted ultrasonic waves fluctuate in the range of 20 kHz to 65 kHz.

[0088] In some embodiments, a maintenance opening is formed on the shell 100, and a maintenance cover is detachably connected to the maintenance opening. The maintenance cover is used to open or close the maintenance opening. When the maintenance cover closes the maintenance opening, the side of the maintenance cover facing the outdoor heat exchanger is the inner side. The insect repellent storage box 500 is arranged on the inner side of the maintenance cover. The insect repellent storage box 500 is arranged inside the shell 100 to avoid direct contact of external rainwater with the insect repellent, thereby preventing the insect repellent from being ineffective.
