[0025] An air conditioner outdoor unit includes a housing 1, an air guide ring 2, a fan 3, an electric control box 4, a radiator 5, a fan mounting box 6, a cooling fan 7, a compressor 8 and a condenser 9. An exhaust port 11 is provided at the upper portion of the housing 1, and the housing 1 includes a panel 12.
[0026] The electric control box 4 and the enclosure 12 are both arranged on the periphery of the housing 1, the enclosure 12 is located below the electric control box 4, and the enclosure 12 is provided with a plurality of first through holes 120; the air guide ring 2, the fan 3, the radiator 5, the fan mounting box 6, the cooling fan 7, the compressor 8 and the condenser 9 are all arranged inside the housing 1, and the compressor 8 and the condenser 9 are connected; the air guide ring 2 and the fan 3 are both installed at the exhaust port 11, the fan 3 is located inside the air guide ring 2, the fan mounting box 6 is installed at the bottom of the electric control box 4, the rear side of the electric control box 4 is provided with a louver window 41, the lower part of the electric control box 4 is provided with a plurality of second through holes 42, the front side of the fan mounting box 6 is provided with an air inlet 60, the cooling fan 7 is installed in the fan mounting box 6, the cooling fan 7 is located at the rear side of the electric control box 4, the radiator 5 is installed on the rear side of the electric control box 4, and the radiator 5 is located above the cooling fan 7.
[0027] An air-conditioning outdoor unit of this solution, such as Figure 1-5As shown, when the electronic control box 4 receives a control signal from the air conditioner indoor unit, it controls the operation of the fan 3, the compressor 8, and the condenser 9. The fan 3 draws in outdoor air and discharges the hot air through the exhaust port 10, thereby maintaining the normal operating temperature of the condenser 6. Because the fan 3 is located within the air guide ring 2, the air guide ring 2 can guide the direction of air flow, improving the air supply efficiency and heat dissipation of the fan 3. By inputting low-temperature, low-pressure refrigerant gas into the compressor 5, the compressor 5 compresses the low-temperature, low-pressure refrigerant gas into high-temperature, high-pressure refrigerant gas, and then delivers the high-temperature, high-pressure refrigerant gas to the condenser 6. The condenser 6 gradually condenses the high-temperature, high-pressure refrigerant gas into a low-temperature, high-pressure refrigerant liquid. After the pressure is reduced, the low-temperature, high-pressure refrigerant liquid enters the evaporator of the air conditioner indoor unit. The low-temperature, low-pressure refrigerant liquid absorbs heat from the indoor air and evaporates into gas, thereby achieving a cooling effect. During operation of the electrical control box 4, the cooling fan 7 is simultaneously activated, allowing the air inside the electrical control box 4 to enter the interior of the fan mounting box 6 through the second through-hole 42. Simultaneously, cooler air from the outside environment enters through the first through-hole 120 of the enclosure 12 and flows into the interior of the fan mounting box 6 through the air inlet 60. In this way, the air inside the electrical control box 4 and the cooler air from the outside environment merge within the fan mounting box 6. The merged air is then blown toward the radiator 5, dissipating heat from the radiator 5 and thereby significantly improving the cooling effect of the electrical control box 4. Furthermore, the provision of the louver window 41 facilitates achieving different degrees of ventilation by adjusting the degree of opening of its blades. When the cooling fan 7 is operating, the hot air inside the electrical control box 4 is discharged by opening the louver window 41, further improving the cooling effect of the electrical control box 4. In one embodiment, the first through-hole 120 and the second through-hole 42 are circular or rectangular holes.
[0028] In this solution, by installing the cooling fan 7 outside the electrical control box 4, the design of the cooling fan 7 is no longer limited by the internal space of the electrical control box 4, compared to the traditional heat dissipation method of installing the cooling fan inside the electrical control box. This allows the cooling fan 7 to fully exert its heat dissipation potential, thereby improving the heat dissipation effect of the electrical control box 4. In addition, this solution promotes air circulation between the interior of the electrical control box 4 and the external environment, continuously removing the heat accumulated in the electrical control box 4 and discharging it to the outside world, thereby effectively improving the heat dissipation effect of the electrical control box 4.
[0029] Preferably, the electric control box 4 includes a box body 43, an electric control main board 44 and a cover plate 45. The electric control main board 44 is installed inside the box body 43, and the cover plate 45 is installed at the front of the box body 43. Figure 1 and Figure 3 As shown, the provision of the cover plate 45 can effectively prevent external moisture or impurities from entering the interior of the box body 43 and causing damage to the electronic control main board 44 , thereby increasing the service life of the electronic control main board 44 .
[0030] Preferably, the electric control box 4 further includes two wire-passing rubber rings 46, and the rear portion of the box body 43 is provided with two wire-passing openings 430, and the two wire-passing rubber rings 46 are respectively arranged at the respective wire-passing openings 430. Figure 1 As shown, the arrangement of the wire-passing opening 430 serves to provide a cable channel, and the arrangement of the wire-passing rubber ring 46 serves to provide sealing protection, buffering and vibration reduction, and fixing of the cables.
[0031] Preferably, it further comprises a water baffle 10, which is installed at the rear of the box body 43 and is located below the shutter window 41. Figure 5 As shown, the arrangement of the water baffle 10 can effectively block water drops or splashes falling from above, preventing them from directly entering the interior of the box body 43 and causing damage to the electronic control mainboard 44.
[0032] Preferably, the radiator 5 includes a base 51 and heat dissipation fins 52, and the heat dissipation fins 52 are mounted on the base 51. In this embodiment, Figure 4 As shown, the base 51 is provided to support the heat dissipation fins 52 and ensure that the heat dissipation fins 52 can be stably mounted thereon. The heat dissipation fins 52 can increase the heat dissipation area to accelerate the transfer and dissipation of heat.
[0033] Preferably, it further comprises a base mounting frame 13, the base mounting frame 13 being mounted on the rear portion of the box body 43, and the base 51 being mounted on the base mounting frame 13. In this embodiment, Figure 5 As shown, the provision of the base mounting frame 13 facilitates the installation of the base 51 , so that the entire radiator 5 can be stably installed on the rear side of the electric control box 4 .
[0034] Preferably, the fan 3 includes a motor 31 and a fan blade 32, and the fan blade 32 is installed at the driving end of the motor 31.
