[0031] The air conditioner outdoor unit 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0032] Reference Figure 1 and Figure 2 As shown, the air-conditioning outdoor unit 100 according to the embodiment of the present utility model may include: a housing 10, a middle partition 20 and an electric control component 30. For example, the air-conditioning outdoor unit 100 may be a variable frequency air-conditioning outdoor unit 100.

[0033] Specifically, the middle partition 20 and the electric control assembly 30 are both located in the housing 10. The middle partition 20 divides the space in the housing 10 into a fan chamber 101 and a compressor chamber 102. The fan chamber 101 is used for heat exchange by the heat exchanger, and the compressor chamber 102 is used to install the compressor 13, which can meet different usage requirements. The electric control assembly 30 is located above the middle partition 20, which can achieve water and electricity separation and improve the safety of the air conditioner outdoor unit 100. The radiator 31 of the electric control assembly 30 is located in the fan chamber 101, which is convenient for heat dissipation of the radiator 31.

[0034] In addition, if Figure 2 and Figure 3 As shown, the housing 10 is provided with a ventilation inlet 11, and the middle partition 20 is provided with a ventilation cavity 21 and a ventilation outlet 22. The ventilation outlet 22 and the ventilation inlet 11 are both connected to the ventilation cavity 21. The ventilation outlet 22 is located above the middle partition 20, and the ventilation outlet 22 is connected to the fan cavity 101. Thus, external air can enter the ventilation cavity 21 through the ventilation inlet 11, and enter the fan cavity 101 from the ventilation outlet 22 through the ventilation cavity 21, so that the external air can be introduced into the radiator 31, so as to meet the demand of inputting external air into the radiator 31 for heat dissipation, and can assist in heat dissipation, effectively increase the air volume passing through the radiator 31, reduce the temperature of the airflow passing through the radiator 31, so that the external airflow exchanges heat with the radiator 31, effectively improve the heat exchange efficiency of the radiator 31, and is conducive to reducing the temperature of the electric control component 30, which can improve the heat dissipation of the electric control component 30, and improve the operation efficiency and stability of the air conditioner outdoor unit 100.

[0035] In some embodiments, when the temperature of the electronic control component 30 is too high, the operating frequency of the compressor 13 can be reduced through control logic, thereby reducing the current and ensuring that the components in the electronic control component 30 operate within a reasonable temperature range to ensure working reliability.

[0036] According to the air-conditioning outdoor unit 100 of the embodiment of the utility model, the space in the shell 10 is divided into a fan chamber 101 and a compressor chamber 102 by the middle partition 20, and the middle partition 20 is provided with a ventilation chamber 21 and a ventilation outlet 22 connected with the ventilation chamber 21, the ventilation outlet 22 is located above the middle partition 20 and connected with the fan chamber 101, the ventilation chamber 21 is connected with the ventilation inlet 11 of the shell 10, the electric control component 30 is located above the middle partition 20, and the radiator 31 of the electric control component 30 is located in the fan chamber 101, so that external air can enter the ventilation chamber 21 through the ventilation inlet 11, and enter the fan chamber 101 from the ventilation outlet 22 through the ventilation chamber 21, and the external air can be introduced into the radiator 31, so that the external airflow exchanges heat with the radiator 31, thereby effectively improving the heat exchange efficiency of the radiator 31, improving the heat dissipation of the electric control component 30, and improving the operating efficiency and stability of the air-conditioning outdoor unit 100.

[0037] In some embodiments of the utility model, a connecting hole is provided on the middle partition plate 20, and the connecting hole connects the fan chamber 101 and the compressor chamber 102, so as to realize air circulation between the fan chamber 101 and the compressor chamber 102, reduce the working temperature of the compressor chamber 102, and ensure the heat dissipation effect of the compressor chamber 102.

[0038] In addition, the ventilation hole 22 is connected to the compressor chamber 102, and the connecting hole is located above the ventilation hole 22, so that a part of the air flowing out from the ventilation outlet can enter the compressor chamber 102. The air entering the compressor chamber 102 can cool down the compressor 13, which is convenient for dissipating heat from the compressor 13 and is beneficial to improving the overall performance of the compressor 13. Another part of the air flowing out from the ventilation outlet can enter the fan chamber 101 through the connecting hole, which can dissipate heat from the radiator 31 and meet the required thermal requirements.

[0039] According to some embodiments of the present invention, along the arrangement direction of the fan cavity 101 and the compressor cavity 102 (for example Figure 1 In the left and right directions shown in the figure, the radiator 31 is opposite to the connecting hole, so that the external air can directly dissipate the heat of the radiator 31 through the connecting hole, which is beneficial to improving the heat dissipation efficiency of the radiator 31, thereby reducing the temperature of the electronic control component 30, improving the heat dissipation of the electronic control component 30, and ensuring the operating efficiency and stability of the air-conditioning outdoor unit 100.

[0040] In some embodiments of the present invention, the ventilation cavity 21 is arranged along the height direction of the middle partition plate 20 (for example Figure 1), and the ventilation inlet 11 is located on the chassis 12 of the housing 10, and the lower end of the ventilation cavity 21 is opposite to and connected with the ventilation inlet 11, which can ensure the effective connection between the ventilation inlet and the ventilation cavity 21, and facilitate the direct entry of external air into the ventilation cavity 21 to meet the required heat dissipation requirements. At the same time, the airflow can flow from bottom to top, and can have the effect of settling dust while introducing external air, and can prevent rainwater from entering the interior of the air-conditioning outdoor unit 100, avoiding problems such as affecting the internal structure of the air-conditioning outdoor unit 100 and failing to work normally, which can extend the service life of the air-conditioning outdoor unit 100 and ensure the normal function of the air-conditioning outdoor unit 100.

[0041] In some embodiments, the fan in the fan cavity 101 will cause negative pressure to form in the fan cavity 101 during operation. Since the ventilation outlet is connected to the fan cavity 101, it can drive the outside air into the ventilation cavity 21 from the ventilation inlet hole 11 at the bottom of the air-conditioning outdoor unit 100, and enter the fan cavity 101 through the ventilation outlet, which is convenient for meeting the air driving needs, makes the structure simple, avoids adding other driving devices, and is conducive to reducing production costs.

[0042] According to some embodiments of the utility model, the ventilation cavity 21 includes a first section and a second section along the up and down direction, and the width of the first section in the arrangement direction of the fan cavity 101 and the compressor cavity 102 remains unchanged, which is convenient for air to flow in the first section and ensures smooth flow, and the second section is connected to the first section and the ventilation inlet, and along the bottom-to-top direction, the width of the second section in the arrangement direction of the fan cavity 101 and the compressor cavity 102 gradually decreases, that is, the second section is formed into a flared structure, so that the air entering the second section can be guided by the wall of the second section, which is convenient for the airflow to enter the ventilation cavity 21, can increase the air flow rate, and is beneficial to improving the heat dissipation effect.

[0043] In some embodiments of the present invention, Figure 2 and Figure 3 As shown, there can be one ventilation inlet hole 11, or there can be multiple ventilation inlet holes 11 arranged at intervals. Different settings of the ventilation inlet holes 11 can meet different usage requirements, and multiple ventilation inlet holes 11 can increase the air intake into the ventilation cavity 21, which is beneficial to improving the heat dissipation effect.

[0044] In the embodiment of the present invention, the number of the ventilation holes 11 can be flexibly set according to actual conditions. For example, the ventilation holes 11 can be Figure 3 Eight are shown, but two, three, four, five, six, seven, nine or more may also be provided, all of which are within the scope of protection of the present utility model.

[0045] According to some embodiments of the present invention, Figure 3As shown, the aperture of the ventilation inlet hole 11 is less than or equal to 10 mm, that is, the aperture of the ventilation inlet hole 11 is Φ and satisfies Φ≤10 mm. Therefore, within the above-mentioned size range, while ensuring the air intake, it is possible to prevent mosquitoes and the like from entering the interior of the air-conditioning outdoor unit 100 through the ventilation inlet hole 11, thereby avoiding damage to the internal structure of the air-conditioning outdoor unit 100 and ensuring the working reliability of the air-conditioning outdoor unit 100. For example, in some specific embodiments, the aperture of the ventilation inlet hole 11 can be 10 mm, 9 mm, 8 mm, 7 mm, 6 mm, 5 mm, 4 mm, etc.

[0046] In the related art, due to the harsh working environment of the air-conditioning outdoor unit, such as high temperature, the working frequency of the air-conditioning outdoor unit is restricted, affecting comfort. In addition, the excessively high temperature of the compressor in the compressor cavity will cause the working frequency to be limited, affecting the normal operation of the compressor.

[0047] Therefore, in some embodiments of the present invention, Figure 1 As shown, a vent hole 23 is provided on the middle partition plate 20, and the vent hole 23 connects the ventilation cavity 21 and the compressor cavity 102, so that part of the air in the ventilation cavity 21 can flow into the compressor cavity 102 through the vent hole 23, which can reduce the operating temperature of the compressor cavity 102, thereby dissipating the heat of the compressor 13, ensuring the normal operation of the compressor 13, and improving the performance of the whole machine.

[0048] In some embodiments, Figure 1 As shown, there may be a plurality of vent holes 23 (greater than or equal to two), and the plurality of vent holes 23 are spaced apart on the middle partition plate 20. The plurality of vent holes 23 can increase the air intake into the compressor chamber 102, which is beneficial to improving the heat dissipation effect.

[0049] According to some embodiments of the present invention, Figure 1 As shown, in the arrangement direction of the fan cavity 101 and the compressor cavity 102, the air vent 23 is opposite to the compressor 13 located in the compressor cavity 102, so that the compressor 13 can directly obtain the flow of cooling air, ensuring reliable heat dissipation of the wall of the compressor 13, and can reduce the operating temperature of the compressor 13, which is beneficial to improving the working efficiency and life of the compressor 13.

[0050] In some embodiments of the present invention, Figure 1As shown, the middle partition 20 includes a first plate body 201 and a second plate body 202. The first plate body 201 divides the space inside the housing 10 into a fan chamber 101 and a compressor chamber 102. The second plate body 202 is connected to the first plate body 201, and the second plate body 202 and the first plate body 201 define a ventilation chamber 21, which is convenient for defining the ventilation chamber 21. The structural strength of the middle partition 20 can be improved by the first plate body 201 and the second plate body 202, and the structure of the middle partition 20 is simple, which is convenient for processing and manufacturing, and is conducive to reducing production costs. At the same time, by adjusting the connection position of the first plate body 201 and the second plate body 202, it is convenient to define the position, size and shape of the ventilation chamber 21, which can adapt to different heat dissipation requirements.

[0051] In some embodiments, the first plate body 201 and the second plate body 202 are connected by riveting to ensure that the first plate body 201 and the second plate body 202 are reliably connected to avoid deformation or loosening, and ensure that the ventilation cavity 21 has a good air guidance effect, thereby ensuring the heat dissipation effect of the air conditioning outdoor unit 100.

[0052] In some embodiments, the middle partition 20 can be a sheet metal part, which has good structural strength and rigidity, thereby ensuring the structural strength and stability of the air-conditioning outdoor unit 100, and is light in weight and easy to transport and install.
