[0049] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0050] The following is for reference. Figures 1-19The present application describes an air conditioner outdoor unit 100, which is typically located outdoors.

[0051] According to an embodiment of this application, the outdoor unit 100 of an air conditioner includes a housing assembly 30 and an electrical control box 10. The electrical control box 10 can be used to control and regulate the operating status of equipment (such as compressors, fans, etc.) in the outdoor unit of the air conditioner.

[0052] Combination Figure 2 and Figure 4 As shown, the shell assembly 30 has a cavity, and a partition 40 is provided inside the cavity. The partition 40 divides the cavity and forms a fan cavity 301 and a compressor cavity 302 arranged along a first direction. The fan cavity 301 can be used to house equipment such as fans and heat exchangers, so that the air in the fan cavity 301 is driven by the fan to achieve air-cooled heat exchange of the heat exchanger; the compressor cavity 302 is used to house equipment such as compressors and electrical control box 10.

[0053] Furthermore, a connecting hole 401 is formed at the partition plate 40, and an air inlet structure 311 is provided on the first sidewall of the housing assembly 30 opposite to the partition plate 40 in the first direction on the compressor cavity 302 side, so that air outside the housing assembly 30 can enter the housing assembly 30 through the air inlet structure 311. Here, the "first direction" refers to the left-right direction of the air conditioner outdoor unit 100.

[0054] Combination Figure 3 and Figure 4 As shown, the electrical control box 10 is connected between the middle partition 40 and the first side plate 31, and the electrical control box 10 includes a box assembly 2, which forms a heat dissipation duct 101. The air outlet side of the heat dissipation duct 101 is connected to the connecting hole 401, so that the air flowing through the heat dissipation duct 101 can be discharged to the fan cavity 301 side through the connecting hole 401. The air inlet side of the heat dissipation duct 101 can be connected to at least one of the air inlet structure 311 and the compressor cavity 302, so that air can be delivered to the heat dissipation duct 101 through the compressor cavity 302 and the outside of the shell assembly 30.

[0055] It is understandable that when the air inlet side of the heat dissipation duct 101 is connected to the air inlet structure 311, the air outside the shell assembly 30 can directly enter the heat dissipation duct 101 through the air inlet structure 311 and be discharged to the fan cavity 301 after flowing through the heat dissipation duct 101; when the air inlet side of the heat dissipation duct 101 is connected to the compressor cavity 302, the air in the compressor cavity 302 can enter the heat dissipation duct 101 and be discharged to the fan cavity 301 after flowing through the heat dissipation duct 101.

[0056] It should be noted that the heat dissipation duct 101 may include multiple sub-ducts, and the multiple sub-ducts are arranged independently of each other, that is, the multiple sub-ducts are not interconnected. In other words, during the process of air flowing through the heat dissipation duct 101, the air in any one sub-duct will not flow into other sub-ducts, thereby ensuring the heat dissipation efficiency of the electrical control box 10.

[0057] Furthermore, taking the heat dissipation duct 101 having two sub-ducts as an example, the two ends of one sub-duct (i.e., the air inlet side and the air outlet side) are connected between the compressor cavity 302 and the connecting hole 401, and the two ends of the other sub-duct are connected between the air inlet structure 311 and the connecting hole 401. At this time, the heat dissipation duct 101 can achieve air intake through two air intake methods (i.e., air intake in the compressor cavity 302 and air intake outside the shell assembly 30), thereby improving the heat dissipation efficiency at the electrical control box 10.

[0058] Reference Figure 16 As shown, the heat dissipation duct 101 has a waterproof structure on the air outlet side. The waterproof structure is used to improve the waterproof performance of the heat dissipation duct 101 on the air outlet side, thereby providing waterproof protection for the components inside the electrical control box 10.

[0059] like Figure 12 As shown, the heat sink 13 is arranged inside the heat dissipation duct 101, and the heat sink 13 is used to exchange heat with the electrical components 12 arranged in the box assembly 2 to improve the heat dissipation efficiency of the electrical components 12. When the air in the heat dissipation duct 101 flows through the heat sink 13, the air can exchange heat with the heat sink 13 to transfer the heat at the heat sink 13 to the fan cavity 301 side, thereby achieving heat dissipation and cooling at the heat sink 13.

[0060] It is understandable that, in addition to the heat sink 13, the electrical control box 10 also contains electrical components 12. By providing a waterproof structure on the air outlet side of the heat dissipation duct 101, it is possible to prevent water, dust and other contaminants from the fan cavity 301 side from entering the heat dissipation duct 101 through the connecting hole 401 and adhering to the electrical components 12, thereby improving the safety and reliability of the electrical control box 10.

[0061] It should be noted that when the fan is running, the airflow in the fan cavity 301 can form a negative pressure area on the side of the partition plate 40 adjacent to the fan cavity 301. Under the action of the negative pressure area, the air in the heat dissipation duct 101 can be discharged to one side of the fan cavity 301 through the connecting hole 401. At the same time, air can be supplied to the heat dissipation duct 101 through the compressor cavity 302 or the outside of the shell assembly 30, thereby forming a flowing airflow in the heat dissipation duct 101. In turn, the heat at the electrical control box 10 can be transferred to one side of the fan cavity 301 through the air, thereby achieving heat dissipation and cooling at the electrical control box 10.

[0062] Currently, the outdoor unit 100 of the air conditioner is located outdoors, resulting in a harsh working environment for the outdoor unit 100. In related technologies, the outdoor unit 100 is equipped with an electrical control box 10. When the outdoor unit 100 is under severe weather conditions, such as rain, rainwater can enter the compressor cavity 302 and splash onto the electrical control box 10. If rainwater splashes onto the electrical control board, it can easily cause short circuits, sparking, and other problems, posing a safety hazard.

[0063] In this application, airflow is generated by creating negative pressure on the fan cavity 301 side to flow through the heat dissipation duct 101, thereby achieving air cooling of the electrical control box 10. A waterproof structure is provided on the air outlet side of the heat dissipation duct 101, which can prevent contaminants on the fan cavity 301 side from entering the electrical control box 10 through the connecting hole 401, thus providing waterproof protection for the electrical control box 10.

[0064] Combination Figure 6 and Figure 7 As shown, in some embodiments of this application, the waterproof structure includes a first waterproof part 291 and a second waterproof part 292. The heat dissipation duct 101 includes a first duct 1011 and a second duct 1012. The first waterproof part 291 is provided at the first air outlet 10112 of the first duct 1011 to prevent water from entering the air outlet side of the first duct 1011. The second duct 1012 is located below the first duct 1011, and the second waterproof part 292 is provided at the second air outlet 10122 of the second duct 1012 to prevent water from entering the air outlet side of the second duct 1012.

[0065] It is understandable that the heat dissipation duct 101 has multiple sub-ducts (i.e., the first duct 1011 and the second duct 1012 mentioned above), thereby transferring heat from the electrical control box 10 to the fan side through multiple sub-ducts, thus improving the heat dissipation and cooling efficiency of the electrical control box 10. At the same time, waterproof structures are respectively provided on the air outlet side of the first duct 1011 and the second duct 1012 to enhance the protection effect of the electrical control box 10.

[0066] The first air duct 1011 and the second air duct 1012 are arranged vertically. (Refer to...) Figure 3 It can be seen that, Figure 3 The arrows in the diagram indicate the airflow path at the electrical control box 10. The first air duct 1011 and the second air duct 1012 are both arranged horizontally. At the first air duct 1011, the air in the compressor cavity 302 flows into the first air duct 1011 and is discharged to one side of the fan cavity 301. At the second air duct 1012, the air outside the shell assembly 30 flows into the second air duct 1012 and is discharged to one side of the fan cavity 301.

[0067] It should be noted that the airflow direction in the first air duct 1011 and the second air duct 1012 is roughly horizontal. When the first air duct 1011 and the second air duct 1012 are arranged vertically, it facilitates the cooperation between the electronic control component 1 in the electronic control box 10 and the heat dissipation air duct 101. This allows multiple electrical components 12 in the PCB board 11 to be arranged in sections, and the sectioned electrical components 12 to be respectively arranged in the first air duct 1011 and the second air duct 1012. Thus, the components in the electronic control box 10 can be cooled and dissipated through the first air duct 1011 and the second air duct 1012, which helps to improve the heat dissipation and cooling efficiency at the electronic control box 10. The electronic control component 1 may include components such as the electrical components 12 and the PCB board 11.

[0068] Reference Figure 4 As shown, in some embodiments of this application, the first air inlet 10111 of the first air duct 1011 is connected to the compressor cavity 302, and the first air outlet 10112 of the first air duct 1011 is connected to the connecting hole 401, so that the air in the compressor cavity 302 can enter the fan cavity 301 side after flowing through the first air duct 1011; the second air inlet 10121 of the second air duct 1012 is connected to the air inlet structure 311, the second air outlet 10122 of the second air duct 1012 is connected to the connecting hole 401, and the radiator 13 is disposed in the second air duct 1012, so that the air outside the air conditioner fan can enter the fan cavity 301 side after flowing through the second air duct 1012.

[0069] It is understandable that when multiple sub-air ducts are provided at the electrical control box 10, if multiple sub-air ducts intake air through the same area, there will be uneven airflow into the multiple sub-air ducts, affecting the air intake effect of some sub-air ducts and weakening the heat dissipation effect at the sub-air ducts with less airflow. In this application, the air intake methods of the first air duct 1011 and the second air duct 1012 are different, thereby ensuring the air intake effect of the first air duct 1011 and the second air duct 1012 and avoiding mutual interference between the air intake actions of the first air duct 1011 and the second air duct 1012.

[0070] It should be noted that the housing assembly 30 is also provided with a corresponding communication structure in the area corresponding to the compressor cavity 302, so as to connect the compressor cavity 302 with the outside of the housing assembly 30, so that the air outside the housing assembly 30 can enter the compressor cavity 302 through the communication structure to meet the requirement of the compressor cavity 302 to deliver air to the first air duct 1011.

[0071] like Figure 17 As shown, in some embodiments of this application, the box assembly 2 has a mounting cavity and a communicating cavity 201 arranged along a first direction.

[0072] The mounting cavity is located on the side of the box assembly 2 near the partition plate 40, and the connecting cavity 201 is located on the side of the box assembly 2 near the first side plate 31. One end of the connecting cavity 201 is connected to a portion of the mounting cavity, and the other end of the connecting cavity 201 is connected to the air inlet structure 311. The mounting cavity and the air inlet structure 311 are arranged at intervals in the first direction through the connecting cavity 201, thereby reserving a certain space between the mounting cavity and the air inlet structure 311, increasing the difficulty for pollutants to reach the mounting cavity through the air inlet structure 311, and meeting the air inlet requirements of the mounting cavity while protecting the devices arranged in the mounting cavity.

[0073] It should be noted that the mounting cavity is used to install and arrange the electronic control components 1, etc., and the connecting cavity 201 is used to connect the mounting cavity with the air inlet structure 311. Air entering the shell assembly 30 through the air inlet structure 311 can flow through the air inlet cavity and then into the mounting cavity, thus reserving a certain space between the mounting cavity and the air inlet structure 311, increasing the difficulty for pollutants such as rainwater mixed in the air to come into contact with the electronic control components 1.

[0074] Combination Figure 16 and Figure 17 As shown in a further embodiment of this application, the inner bottom wall of the connecting cavity 201 gradually rises from the side near the first side plate 31 toward the mounting cavity side, thereby helping to discharge rainwater and other pollutants that enter the connecting cavity 201 and protecting the electrical control component 1 arranged on the mounting cavity side.

[0075] It is understood that the connecting cavity 201 is connected to the outside of the shell assembly 30 through the air inlet structure 311. When air mixed with pollutants such as rainwater enters the connecting cavity 201 through the air inlet structure 311, the rainwater can adhere to the wall surface of the connecting cavity 201 and flow downward (and also away from the mounting cavity) under the action of gravity, reducing the risk of rainwater entering the mounting cavity and improving the protection effect on the electrical control assembly 1 in the electrical control box 10. Specifically, when rainwater adheres to the bottom wall of the connecting cavity 201, since the bottom wall is inclined downward, the rainwater at the bottom wall can flow downward and also to the side of the air inlet structure 311, so as to facilitate the discharge of rainwater in the connecting cavity 201; when rainwater adheres to the side wall (i.e., the vertically arranged wall surface) of the connecting cavity 201, the rainwater can flow to the bottom wall side and be discharged outward along the extension direction of the bottom wall towards the air inlet structure 311 side.

[0076] In some embodiments of this application, the cross-sectional dimension of the connecting cavity 201 in the first direction gradually decreases from the air inlet structure 311 toward the mounting cavity side, so that the air velocity in the connecting cavity 201 gradually increases toward the mounting cavity side, thereby improving the airflow effect at the connecting cavity 201 and ensuring the air velocity blown from the oil connecting cavity 201 toward the mounting cavity side.

[0077] It is understandable that, according to the fluid continuity equation Q = vA (Q: flow rate; A: flow area; v: velocity), when the flow rate of the fluid (i.e., the air mentioned above) remains constant, the fluid velocity will increase as the flow area decreases.

[0078] Combination Figure 16 and Figure 17 As shown, at the connecting cavity 201 of the box assembly 2, the bottom wall can be inclined upwards towards the mounting cavity side, and the cross-sectional area of ​​the connecting cavity 201 gradually decreases from the air inlet structure 311 towards the mounting cavity side. Therefore, while ensuring the airflow velocity from the connecting cavity 201 towards the mounting cavity side, the protection effect of the connecting cavity 201 on the mounting cavity side can be improved, reducing the risk of short circuits and failures of the electrical control assembly 1 due to contaminants.

[0079] Combination Figure 3 and Figure 17 As shown, in some embodiments of this application, the mounting cavity includes a first mounting cavity 2021 and a second mounting cavity 2022 arranged in a vertical direction, and a first air duct 1011 is formed at the first mounting cavity 2021, and the second mounting cavity 2022 and the connecting cavity 201 together form a second air duct 1012.

[0080] It is understood that there are multiple electrical components 12 in the electrical control box 10. The first mounting cavity 2021 and the second mounting cavity 2022 are respectively used to cooperate with the electrical components 12 in the electrical control box 10. Thus, according to the heat dissipation requirements of the electrical components 12, multiple electrical components 12 can be arranged in the areas corresponding to the first mounting cavity 2021 and the second mounting cavity 2022, and the electrical components 12 can be cooled down by the first air duct 1011 and the second air duct 1012 respectively.

[0081] The first air duct 1011 and the second air duct 1012 are arranged independently of each other. "Independent" means that the first air duct 1011 and the second air duct 1012 are not connected to each other. That is, air in the first air duct 1011 will not flow into the second air duct 1012, preventing air flowing through the electrical components 12 in the first air duct 1011 from flowing into the second air duct 1012 and affecting the heat dissipation effect on the electrical components 12 arranged in the second air duct 1012. Similarly, air in the second air duct 1012 will not flow into the first air duct 1011, preventing air flowing through the electrical components 12 in the second air duct 1012 from flowing into the first air duct 1011 and affecting the heat dissipation effect on the electrical components 12 arranged in the first air duct 1011.

[0082] Combination Figure 13 and Figure 17As shown, in some embodiments of this application, the first mounting cavity 2021 and the second mounting cavity 2022 are respectively open to the same side in the second direction. The electrical control box 10 includes a PCB board 11, which is vertically arranged on the open side of the first mounting cavity 2021 and the second mounting cavity 2022. The heat sink 13 is disposed on the side of the PCB board 11 opposite to the second mounting cavity 2022, so that the heat sink 13 can be arranged at the second air duct 1012 (which is jointly formed by the second mounting cavity 2022 and the connecting cavity 201).

[0083] It should be noted that the "second direction" mentioned above refers to the front-to-back direction of the outdoor unit 100 of the air conditioner. (Combined with...) Figure 3 and Figure 13 As shown, the PCB board 11 is arranged vertically, and a portion of the PCB board 11 is positioned opposite to the first mounting cavity 2021 in the second direction, while a portion of the PCB board 11 is positioned opposite to the second mounting cavity 2022 in the second direction. Thus, the PCB board 11 can guide the airflow direction in the first mounting cavity 2021 and the second mounting cavity 2022, preventing air from escaping from the open side in the second direction from the mounting cavities (i.e., the first mounting cavity 2021 and the second mounting cavity 2022).

[0084] Since the first mounting cavity 2021 and the second mounting cavity 2022 are open to one side of the PCB board 11, the components arranged on the PCB board 11 (such as electrical components 12 and heat sinks 13) can be inserted through the open side of the mounting cavity, which facilitates the installation and cooperation of the electrical control assembly 1 and the box assembly 2.

[0085] Reference Figure 14 As shown, the electrical components 12 and the heat sink 13 are arranged on the same side of the PCB board 11, that is, the side of the PCB board 11 opposite to the mounting cavity. This makes it easier to place the heat sink 13 and the electrical components 12 arranged on the PCB board 11 into the mounting cavity to achieve air cooling. It also reduces the installation difficulty of the electrical components 12 and the PCB board 11, avoids double-sided soldering on the PCB board 11, and improves the production efficiency of the electrical control component 1.

[0086] Combination Figure 12 and Figure 13 As shown, in some embodiments of this application, an electrical component 12 is provided in the electrical control box 10. The electrical component 12 is located on the side of the PCB board 11 opposite to the mounting cavity, so that the electrical component 12 extends into the mounting cavity when the PCB board 11 and the box assembly 2 are engaged, and is cooled by the air flowing through the mounting cavity.

[0087] The electrical component 12 is positioned at a height no lower than the bottom of the heat sink 13, thereby preventing water adhering to the heat sink 13 from falling onto the electrical component 12 located below the heat sink 13. (Refer to...) Figure 20As shown, a horizontally extending water guide channel 133 is formed at the lower part of the radiator 13. The horizontal water guide channel 133 can drain water and other contaminants from the radiator 13 to prevent water and other contaminants from accumulating on the radiator 13; see reference. Figure 21 As shown, a vertically extending water guide groove 134 is formed on the heat dissipation substrate 131 (the surface opposite to the power device) of the heat sink 13. The vertical water guide groove 134 can guide water from the heat dissipation substrate 131 downwards to prevent water and other contaminants from accumulating on the heat sink 13. Therefore, by arranging the height of the electrical device 12 at a position not lower than the bottom of the heat sink 13, it is possible to effectively prevent water dripping from the heat sink 13 from falling onto the electrical device 12.

[0088] It should be noted that the electrical components 12 may include power devices (such as bridge rectifiers), capacitive devices, and inductive devices, etc., and the heat generated by each electrical component 12 during operation varies. For example, compared to other electrical components 12 (such as capacitive devices), power devices generate more heat during operation. Therefore, the electrical components 12 can be arranged in zones according to the differences in the heat generated during operation. For example, power devices can be arranged within the second mounting cavity 2022, and the power devices can cooperate with the heat sink 13 for heat exchange, thereby improving the heat dissipation efficiency at the power devices. Thus, according to the heat dissipation requirements of the electrical components 12, the electrical components 12 can be arranged in zones on the PCB board 11 to improve the heat dissipation and cooling effect of the electrical control box 10 on the electrical components 12.

[0089] Reference Figure 6 and Figure 7 As shown, when the electronic control component 1 and the box component 2 are installed and matched, some of the electrical components 12 can be placed outside the first mounting cavity 2021. The air that enters the first mounting cavity 2021 through the compressor cavity 302 can also flow through the electrical components 12 located outside the first mounting cavity 2021 to achieve heat dissipation and cooling of the electrical components 12.

[0090] In some embodiments of this application, the heat sink 13 includes a heat sink substrate 131 and a plurality of heat sinks 132. The heat sink substrate 131 is connected to the PCB board 11, and the plurality of heat sinks 132 are disposed on the side of the heat sink substrate 131 facing away from the PCB board 11. The heat from the power device can be transferred from the heat sink substrate 131 to the heat sinks 132. When the air in the second air duct 1012 flows through the heat sinks 132, it can exchange heat with the heat sinks 132 and transfer the heat to the fan cavity 301, thereby achieving cooling at the power device. Furthermore, by cooperating with the power device, the heat sink 13 can improve the heat dissipation and cooling efficiency at the power device.

[0091] Further integration Figure 20 and Figure 21As shown, multiple heat sinks 132 are arranged at intervals along the vertical direction, and a heat dissipation channel is formed between any two adjacent heat sinks 132. The extension direction of the heat dissipation channel is roughly the same as the extension direction of the second air duct 1012, thereby reducing the resistance encountered by the air in the second air duct 1012 when flowing through the heat sinks 132, and improving the air circulation effect in the second air duct 1012. It should be noted that the "extension direction of the heat dissipation channel" refers to the approximate direction of air circulation in the heat dissipation channel.

[0092] In some embodiments of this application, the heat sink 132 extends in a wave-like manner in the second direction, thereby increasing the contact area between the heat sink 132 and the air in the first air duct 1011, thereby improving the heat dissipation efficiency of the heat sink 13 and enhancing the heat dissipation and cooling effect of the heat sink 13 on the power device.

[0093] Reference Figure 14 As shown, in some embodiments of this application, the heat sink 13 further includes a heat sink bracket 14, which is disposed on the PCB board 11 and is used to connect and cooperate with the heat sink substrate 131. The heat sink bracket 14 is a mounting carrier for the heat sink 13, so as to support the heat sink 13 in a second direction and connect and fix the heat sink 13 to the PCB board 11.

[0094] The heat sink bracket 14 is arranged on the side of the PCB board 11 opposite to the second mounting cavity 2022. The heat sink bracket 14 can surround and shield the power device in the circumferential direction, and the heat sink 13 can also shield the power device to fully shield the power device and prevent dust and other contaminants from adhering to the power device.

[0095] like Figure 17 As shown, in some embodiments of this application, the box assembly 2 includes a first enclosure 21, a second enclosure 22, a third enclosure 23 and a fourth enclosure 24. The first enclosure 21 and the third enclosure 23 are arranged opposite each other in the vertical direction, and the second enclosure 22 and the fourth enclosure 24 are arranged opposite each other in the second direction. The first enclosure 21, the second enclosure 22, the third enclosure 23 and the fourth enclosure 24 surround each other to form a second air duct 1012.

[0096] The second enclosure 22 and the fourth enclosure 24 are respectively connected between the first enclosure 21 and the third enclosure 23, so that the first enclosure 21, the second enclosure 22, the third enclosure 23 and the fourth enclosure 24 together form the second air duct 1012, making the structure of the box assembly 2 at the second air duct 1012 regular (roughly rectangular), which is convenient for installation and cooperation with the electrical control assembly 1.

[0097] In a further embodiment of this application, the fourth enclosure 24 is disposed on the side of the second air duct 1012 adjacent to the PCB board 11, and the fourth enclosure 24 forms a first clearance opening, through which devices arranged on the PCB board 11 (such as heat sink 13) can extend into the second air duct 1012.

[0098] Understandably, the box assembly 2 of this application has a first clearance opening at the fourth enclosure 24. The first clearance opening can allow the heat sink 13 arranged on the PCB board 11 to pass through the first clearance opening into the second air duct 1012, thereby improving the heat dissipation and cooling effect of the air in the second air duct 1012 on the heat sink 13. In other words, the heat sink 13 is arranged in the airflow path in the second air duct 1012, and the air flowing through the second air duct 1012 can fully contact the heat sink 13, improving the heat dissipation effect at the heat sink 13.

[0099] like Figure 17 As shown, in some embodiments of this application, the first enclosure 21 is disposed above the third enclosure 23, and the side wall of the third enclosure 23 opposite to the first enclosure 21 is the inner bottom wall of the second air duct 1012. The inner bottom wall extends upward or downward from the side of the second enclosure 22 to the side of the fourth enclosure 24.

[0100] It is understood that the third enclosure 23 is connected between the second enclosure 22 and the fourth enclosure 24, and the second enclosure 22 and the fourth enclosure 24 are arranged opposite each other in the second direction (also the front-rear direction of the air conditioner outdoor unit 100). Taking the second enclosure 22 as being located on the front side of the fourth enclosure 24 as an example, when the inner bottom wall extends downward towards the second enclosure 22, if water falls on the third enclosure 23, the inner bottom wall can guide the water towards the second enclosure 22 (i.e., the front side of the box assembly 2), making it difficult for water to remain on the third enclosure 23; when the inner bottom wall extends downward towards the fourth enclosure 24, if water falls on the third enclosure 23, the inner bottom wall can guide the water towards the fourth enclosure 24 (i.e., the rear side of the box assembly 2), making it difficult for water to remain on the third enclosure 23.

[0101] In a further embodiment of this application, a drain port 231 is formed at the third enclosure 23. The drain port 231 connects the second air duct 1012 and the compressor cavity 302. Water in the second air duct 1012 can be discharged outward through the drain port 231 to prevent water and other pollutants from remaining in the second air duct 1012.

[0102] Understandably, the location of the drain outlet 231 within the third enclosure 23 can be designed according to drainage requirements, preferably positioned on the side of the third enclosure 23 that guides the water flow. Because the inner bottom wall of the third enclosure 23 is inclined downwards, water in the second air duct 1012 is less likely to remain on the third enclosure 23. Under gravity, the third enclosure 23 can guide the water towards the drain outlet 231, allowing the water in the second air duct 1012 to be discharged outwards from the drain outlet 231. If rainwater or other contaminants are present in the electrical control box 10, the electrical control component 1 will be in a humid environment, making it prone to rusting at locations such as solder joints.

[0103] In some embodiments of this application, the box assembly 2 includes a fifth enclosure 25, a sixth enclosure 26 and a seventh enclosure 27. The fifth enclosure 25 and the sixth enclosure 26 are arranged opposite to each other and spaced apart in a first direction. The seventh enclosure 27 is connected between the fifth enclosure 25 and the sixth enclosure 26, and the seventh enclosure 27 is arranged opposite to the PCB board 11 in a second direction.

[0104] The fifth enclosure 25, the sixth enclosure 26, and the seventh enclosure 27 surround and form a first mounting cavity 2021 that opens to one side of the PCB board 11. When the PCB board 11 is installed and engaged with the box assembly 2, the PCB board 11 can block the open side of the first air duct 1011 to limit the airflow path within the first air duct 1011.

[0105] It is understood that the fifth enclosure 25, the sixth enclosure 26 and the seventh enclosure 27 can surround and form a first mounting cavity 2021 that opens to one side of the PCB board 11, and form an opening structure at the first mounting cavity 2021 that is suitable for the electrical components 12 arranged on the PCB board 11 to avoid, thereby facilitating the electrical components 12 on the PCB board 11 to extend into from the open side of the first mounting cavity 2021 (i.e. the side opposite to the seventh enclosure 27).

[0106] like Figure 17 As shown, in some embodiments of this application, the box assembly 2 further includes a support plate segment 28, which is connected between the fifth enclosure 25 and the sixth enclosure 26 to support the fifth enclosure 25 and the sixth enclosure 26 in the vertical direction, thereby improving the structural strength of the box assembly 2.

[0107] Reference Figure 17As shown, the support plate segment 28 is located on the air outlet side adjacent to the first air duct 1011, and the support plate segment 28, together with the fifth enclosure plate 25, the sixth enclosure plate 26, and the seventh enclosure plate 27, can define the first air outlet 10112 of the first air duct 10111, thereby improving the structural strength of the box assembly 2 at the first air outlet 10112. At the same time, the support plate segment 28 can also avoid the electrical components 12 arranged on the PCB board 11, so as to effectively prevent interference between the support plate segment 28 and the electrical components 12, and facilitate the assembly of the electronic control component 1 and the box assembly 2.

[0108] Reference Figure 17 In some embodiments of this application, the first enclosure 21 and the fifth enclosure 25 are coplanar and integrally arranged, thereby saving the space occupied by the box assembly 2 in the vertical direction and making the layout of the electrical control assembly 1 in the electrical control box 10 compact.

[0109] It should be noted that the fifth enclosure 25 is arranged vertically on the side of the sixth enclosure 26 adjacent to the second air duct 1012. That is, when the fifth enclosure 25 and the first enclosure 21 are integrated, the sixth enclosure 26, the fifth enclosure 25 (which is also the first enclosure 21), and the third enclosure 23 are arranged alternately in the vertical direction.

[0110] It is understood that the first enclosure 21 and the fifth enclosure 25 in the box assembly 2 are arranged coplanarly, thereby constructing the first enclosure 21 and the fifth enclosure 25 as a single partition structure. The partition structure separates the first air duct 1011 and the second air duct 1012, that is, the two sides of the partition structure in the vertical direction face the first air duct 1011 and the second air duct 1012 respectively. The above-mentioned arrangement of integrating the first enclosure 21 and the fifth enclosure 25 can reduce the number of board structures required to form the first air duct 1011 and the second air duct 1012 in the box assembly 2, and make the first air duct 1011 and the second air duct 1012 arranged adjacent to each other in the vertical direction, so that the components on the PCB board 11 (such as heat sink 13, capacitive devices, power devices, etc.) are arranged compactly, thereby improving the space utilization of the electrical control box 10.

[0111] Reference Figure 16 In some embodiments of this application, the first waterproof part 291 is constructed as a first louver. The first louver in the first louver can block the first air outlet 10112 of the first air duct 1011 to prevent pollutants on the fan cavity 301 side from entering the first air duct 1011 through the first air outlet 10112, thereby protecting the electrical components 12 arranged in the first air duct 1011.

[0112] Reference Figure 16In some embodiments of this application, the second waterproof part 292 is constructed as a second louver. The second louver in the second louver can block the second air outlet 10122 of the second air duct 1012 to prevent pollutants on the fan cavity 301 side from entering the second air duct 1012 through the second air outlet 10122, thereby protecting the devices (such as electrical components 12, heat sinks 13, etc.) arranged in the second air duct 1012.

[0113] like Figure 18 As shown, in some embodiments of this application, the partition plate 40 is provided with a third louver 41 at the connecting hole 401, so as to block the connecting hole 401 through the louvers of the third louver 41, so as to prevent pollutants on the fan cavity 301 side from passing through the connecting hole 401 and entering the heat dissipation air duct 101, and to protect the electrical control box 10 arranged on the compressor cavity 302 side.

[0114] It is understandable that the third louver 41 also has a protective function. When the heat dissipation duct 101 is provided with the first louver and the second louver on the air outlet side and the third louver 41 is provided at the connecting hole 401, a multi-layer protective structure can be formed at the connection between the heat dissipation duct 101 and the fan cavity 301 to improve the waterproof effect at the connection between the heat dissipation duct 101 and the fan cavity 301.

[0115] like Figure 4 As shown, in some embodiments of this application, the air inlet structure 311 is constructed as a fourth louver, which can protect the air inlet side of the heat dissipation duct 101 through the louvers of the fourth louver, so as to prevent contaminants outside the housing assembly 30 from directly entering the heat dissipation duct 101 through the air inlet structure 311, and thus protect the electrical control box 10.

[0116] In some embodiments of this application, panel 32 includes a first panel 321 and a second panel 322, which are arranged sequentially and connected along a first direction. The adjacent portions of the first panel 321 and the second panel 322 are connected and fitted with the partition plate 40. That is, the first panel 321 is the component in panel 32 corresponding to the fan cavity 301, and the second panel 322 is the component in panel 32 corresponding to the compressor cavity 302. This facilitates the assembly of the housing assembly 30 and the partition plate 40, and also facilitates the inspection and maintenance of the devices in the fan cavity 202 and the compressor cavity 302.

[0117] Understandably, when it is necessary to disassemble the electrical control box 10, only the second panel 322 needs to be removed to open the compressor cavity 302 on one side of the panel 32, making it convenient for operators to install and remove the electrical control box 10 from the side of the panel 32. Similarly, if it is necessary to inspect and repair the devices (such as fans, heat exchangers, etc.) in the fan cavity 301, removing the first panel 321 will fully expose the devices in the fan cavity 202 from one side of the panel 32, making it convenient for operators to operate.

[0118] The air conditioner outdoor unit 100 according to the embodiments of this application has at least the following advantages:

[0119] (1) The electrical control box 10 arranged in the compressor cavity 302 forms a heat dissipation duct 101, and the air outlet side of the heat dissipation duct 101 is connected to the fan cavity 301 so that the air in the heat dissipation duct 101 can be discharged to the side of the fan cavity 301 through the negative pressure formed on the side of the fan cavity 301, thereby realizing air cooling at the electrical control box 10. Furthermore, a protective structure (such as the louver structure mentioned above) is provided at the connection between the heat dissipation duct 101 and the fan cavity 301 to improve the protection effect of the electrical control box 10 and prevent rainwater and other pollutants from entering the electrical control box 10 from the side of the fan cavity 301.

[0120] (2) Multiple sub-channels are formed at the heat dissipation duct 101. Sub-channels (such as the first channel 1011) can be connected between the compressor cavity 302 and the fan cavity 301. Sub-channels (such as the second channel 1012) can be connected between the outside of the shell assembly 30 and the fan cavity 301. Thus, the heat dissipation and cooling of the electrical control box 10 can be achieved through multiple flow paths, thereby improving the heat dissipation effect of the electrical control box 10.

[0121] (3) The bottom of the box assembly 2 is provided with a drainage structure. Water located in the box assembly 2 (e.g., the second air duct 1012) can be discharged through the drainage structure, thereby preventing rainwater and other pollutants from remaining in the electrical control box 10 and improving the reliability of the electrical control box 10.

[0122] According to the embodiments of this application, the air conditioner includes the above-mentioned outdoor unit 100. The advantages of the air conditioner and the outdoor unit 100 are the same, and will not be repeated here.
