[0034] 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.

[0035] The following is for reference. Figures 1-9 The present application describes an air conditioner outdoor unit 100, which is arranged outdoors.

[0036] An air conditioner outdoor unit 100 according to an embodiment of this application includes an electrical control box 10 and a housing assembly 20.

[0037] Combination Figure 2 , Figure 4 and Figure 5 As shown, the electrical control box 10 has a heat dissipation duct 101, and the heat dissipation duct 101 has an air inlet 1011 and an air outlet 1012. The air inlet 1011 is used to allow air to flow into the heat dissipation duct 101, and the air outlet 1012 is used to allow air to be discharged from the heat dissipation duct 101.

[0038] Combination Figure 4 and Figure 5 As shown, the shell assembly 20 has a cavity, and a partition 30 is provided inside the cavity. The partition 30 divides the cavity to form a compressor cavity 201 and a fan cavity 202. The shell assembly 20 is provided with an air inlet structure 212 that connects the compressor cavity 201 with the outside of the shell assembly 20. Air outside the shell assembly 20 can enter the compressor cavity 201 through the air inlet structure 212. The air inlet 1011 of the heat dissipation duct 101 is connected to the compressor cavity 201, so that air in the compressor cavity 201 can enter the heat dissipation duct 101 through the air inlet 1011.

[0039] Furthermore, the partition plate 30 has a connecting hole 301, and the air outlet 1012 is located at the connecting hole 301. The air outlet 1012 is connected to the fan cavity 202, so that the air in the heat dissipation duct 101 can be discharged to one side of the fan cavity 202 through the air outlet 1012 and the connecting hole 301. Thus, the air flowing through the heat dissipation duct 101 can transfer the heat at the electrical control box 10 to one side of the fan cavity 202, thereby achieving heat dissipation and cooling of the electrical control box 10 and improving the heat dissipation effect at the electrical control box 10.

[0040] Combination Figure 2 and Figure 3 As shown, the electrical control box 10 is arranged in the compressor cavity 201 and at the partition plate 30 so that the air outlet 1012 of the electrical control box 10 corresponds to the ventilation hole of the partition plate 30, and the air inlet 1011 of the electrical control box 10 is kept in communication with the compressor cavity 201 so that the air in the compressor cavity 201 can flow into the heat dissipation air duct 101 through the air inlet 1011.

[0041] The outdoor unit 100 of the air conditioner is equipped with devices such as a fan, a heat exchanger, and a compressor. For example, the heat exchanger and fan are arranged in the fan chamber 202, and the compressor and piping are arranged in the compressor chamber 201. It can be understood that when the fan is running, airflow can be generated in the fan chamber 202, and a negative pressure area can be formed near the connecting hole 301. Since the air outlet 1012 of the heat dissipation duct 101 is connected to one side of the fan cavity 202 through the connecting hole 301, under the action of negative pressure, the air in the heat dissipation duct 101 will be transported to the fan cavity 202 through the air outlet 1012. At the same time, the air in the compressor cavity 201 can be replenished into the heat dissipation duct 101 through the air inlet 1011, so as to form an airflow from the air inlet 1011 to the air outlet 1012 in the heat dissipation duct 101. When the airflow flows through the electrical control box 10, it can transfer the heat at the electrical control box 10 to the fan cavity 202.

[0042] Reference Figure 5 As shown, Figure 5 The middle arrow indicates the direction of airflow. Air outside the housing assembly 20 can enter the compressor chamber 201 through the air inlet structure 212, and air in the compressor chamber 201 can enter the heat dissipation duct 101 through the air inlet 1011. Air in the heat dissipation duct 101 can be discharged to the fan chamber 202 through the air outlet 1012. Air entering the fan chamber 202 can be discharged to the outside of the fan chamber 202 by the action of the fan. Thus, a unidirectional airflow is formed at the electrical control box 10 through the heat dissipation duct 101, achieving heat dissipation at the electrical control box 10 through air cooling.

[0043] It should be noted that currently, in air conditioner outdoor units, the electrical control box is located inside the unit's casing. This box generates heat during operation, requiring cooling to ensure its stability and reliability. In related technologies, the electrical control box typically works in conjunction with the refrigerant piping for heat exchange and cooling, resulting in a complex structure that hinders its placement within the outdoor unit and increases production costs.

[0044] According to the embodiment of this application, under the negative pressure on one side of the fan cavity 202, the air outside the shell assembly 20 can enter the compressor cavity 201 through the air inlet structure 212 and be transported to the side of the heat dissipation duct 101. The air flowing through the heat dissipation duct 101 can be discharged to the side of the fan cavity 202, thereby cooling the electrical control box 10 by air cooling, so as to improve the heat dissipation effect of the air conditioner outdoor unit 100 at the electrical control box 10.

[0045] like Figure 4 As shown, in some embodiments of this application, the shell assembly 20 includes a shell body 21 and a panel 22. The shell body 21 has a receiving cavity that opens to the front side, and the panel 22 is detachably mounted on the open end of the shell body 21, and the panel 22 and the shell body 21 define a cavity.

[0046] The panel 22 can shield the equipment arranged in the cavity from the front of the outdoor unit 100, and the air outlet structure of the fan cavity 202 is formed in the area corresponding to the panel 22 and the fan cavity 202. When it is necessary to inspect and maintain the equipment in the outdoor unit 100, the panel 22 can be removed from the housing 21 to expose the equipment in the cavity from the front of the outdoor unit 100, making it convenient for operators to operate.

[0047] It should be noted that in related technologies, the outdoor unit 100 of the air conditioner is usually installed in a pigeon coop installation scenario, which makes the inspection or maintenance of the outdoor unit 100 quite difficult. Furthermore, when it is necessary to inspect or maintain equipment such as the electrical control box 10 in the outdoor unit 100, the top cover 211 is usually removed to expose the equipment; however, this is difficult to do when the outdoor unit 100 is installed in a pigeon coop.

[0048] In this application, the equipment (such as the electrical control box 10) arranged in the cavity can be exposed by removing the panel 22, so that the operator can operate from the front of the air conditioner outdoor unit 100, reducing the difficulty of maintenance of the air conditioner outdoor unit 100.

[0049] like Figure 2As shown, in some embodiments of this application, the air intake structure 212 is formed on the housing body 21, and the air intake structure 212 is located in the area of ​​the housing body 21 corresponding to the compressor cavity 201, so that air located outside the housing assembly 20 can directly enter the compressor cavity 201 through the air intake structure 212.

[0050] The shell body 21 can be composed of plate structures such as top cover 211, bottom plate, side plate and back plate 213. The air inlet structure 212 can be formed on at least one of the top cover 211, side plate and back plate 213, and the air inlet structure 212 is located in the part of the plate structure corresponding to the compressor cavity 201.

[0051] Combination Figure 2 and Figure 4 As shown, in one specific embodiment of this application, the air inlet structure 212 is disposed on the back plate 213, so that air can be delivered into the compressor cavity 201 through the back plate 213; in another specific embodiment of this application, the air inlet structure 212 is disposed on the right side plate, so that air can be delivered into the compressor cavity 201 through the right side plate.

[0052] It is understandable that placing the air intake structure 212 at a lateral position in the compressor cavity 201 (e.g., back plate 213, side plate) can reduce the entry of external contaminants (e.g., water, dust, etc.) into the compressor cavity 201 through the air intake structure 212 while ensuring the air intake effect at the air intake structure 212.

[0053] In some other embodiments of this application, an air inlet structure 212 is formed on a panel 22, thereby allowing air to be supplied from the panel 22 into the compressor chamber 201.

[0054] It should be noted that multiple air intake structures 212 as described above can be provided in the housing assembly 20, such as air intake structures 212 being provided on the panel 22 and the back panel 213 respectively, thereby improving the air intake effect at the compressor cavity 201.

[0055] like Figure 5 and Figure 6 As shown, in some embodiments of this application, the electrical control box 10 is disposed inside the compressor cavity 201 and is connected to the partition plate 30. The air inlet 1011 of the heat dissipation duct 101 is opposite to and spaced apart from the panel 22, thereby leaving a gap between the air inlet 1011 and the panel 22 for air in the compressor cavity 201 to enter the air inlet 1011 to meet the air intake requirements of the electrical control box 10.

[0056] In a further embodiment of this application, the minimum distance between one end of the electrical control box 10 forming the air inlet 1011 and the wall of the panel 22 facing the compressor cavity 201 is L1, and satisfies the relationship: L1≥20mm. When L1 meets the above parameter range, sufficient space can be reserved between the air inlet 1011 of the heat dissipation duct 101 and the panel 22 to meet the air intake requirements at the air inlet 1011.

[0057] It is understandable that the air inlet 1011 is open to one side of the panel 22. The minimum distance between the air inlet 1011 and the panel 22 refers to the vertical distance between the position of the air inlet 1011 and the wall of the panel 22 facing the compressor cavity 201. If the distance between the air inlet 1011 and the panel 22 does not meet the above parameter range, the air intake effect of the heat dissipation duct 101 will be deteriorated, resulting in a reduction in the air volume within the heat dissipation duct 101, which will fail to meet the heat dissipation and cooling requirements of the electrical control box 10.

[0058] In some embodiments of this application, a first louver (not shown) is provided at the connecting hole 301. The first louver of the first louver is inclined from the connecting hole 301 toward the fan cavity 202 side, so as to prevent contaminants (such as water, dust, etc.) on the fan cavity 202 side from entering the heat dissipation duct 101 through the connecting hole 301, and to protect the electrical components 122 and other components of the electrical control box 10 arranged in the heat dissipation duct 101.

[0059] It is understandable that the fan cavity 202 is externally connected to the housing assembly 20. When air from outside the housing assembly 20 flows into the fan cavity 202, the air may contain contaminants such as water and dust. This could lead to a risk that contaminants could enter the heat dissipation duct 101 through the connecting hole 301 when the air flows through it. Therefore, by setting a first louver at the connecting hole 301, the connection between the heat dissipation duct 101 and the fan cavity 202 can be maintained while reducing the risk of contaminants entering the heat dissipation duct 101 through the connecting hole 301, thus improving the safety and reliability of the electrical control box 10.

[0060] In some other embodiments of this application, the air inlet structure 212 is configured as a second louver to prevent contaminants outside the housing assembly 20 from entering the compressor cavity 201, thereby satisfying the air inlet requirements of the compressor cavity 201 while protecting the equipment inside the compressor cavity 201.

[0061] like Figure 2 As shown, the second louver of the second louver is inclined downward towards the outside of the shell assembly 20, and there are multiple second louvers arranged vertically in sequence to improve the protective effect of the shell body 21 on the air intake structure 212.

[0062] It is understood that in this application, a first louver and a second louver can be provided simultaneously, thereby preventing contaminants from the outside of the shell assembly 20 from entering the compressor cavity 201 side by providing a protective structure at the communication position, thus providing good protection for the equipment arranged in the compressor cavity 201.

[0063] like Figure 3 and Figure 7 As shown, in some embodiments of this application, the partition 30 includes a first plate segment 31 and a second plate segment 32. The first plate segment 31 is arranged vertically and extends from the panel 22 side to the back plate 213 side of the shell body 21. The second plate segment 32 is arranged vertically and is connected to the end of the first plate segment 31 near the back plate 213. The second plate segment 32 extends from the connection with the first plate segment 31 to the side away from the panel 22. The second plate segment 32 is inclined relative to the first plate segment 31.

[0064] The partition 30 is vertically arranged within the cavity to separate the horizontally arranged fan cavity 202 and compressor cavity 201. Figure 3 and Figure 5 As shown, the partition 30 in the shell assembly 20 is arranged from front to back. That is, the first plate segment 31 extends from the side adjacent to the panel 22 toward the back plate 213, and the second plate segment 32 extends further from the first plate segment 31 toward the back plate 213. The second plate segment 32 is inclined relative to the first plate segment 31, so that at least part of the second plate segment 32 is arranged opposite to the back plate 213 in the front-back direction.

[0065] Reference Figure 5 When air from outside the housing assembly 20 enters the fan cavity 202 from the back panel 213 side, the air can be blown towards the side of the second plate segment 32 facing the fan cavity 202 and further discharged to the air outlet structure on the panel 22 side. Since the second plate segment 32 is inclined relative to the first plate segment 31, a corner structure is formed at the adjacent position of the first plate segment 31 and the second plate segment 32, reducing the obstruction of the airflow from back to front in the fan cavity 202 by the first plate segment 31 and ensuring the airflow effect on one side of the fan cavity 202.

[0066] like Figure 6 As shown, in some embodiments of this application, a connecting hole 301 is formed on the first plate segment 31. That is, the air outlet 1012 of the heat dissipation duct 101 is disposed opposite to the first plate segment 31, so that when the electrical control box 10 is connected and engaged with the middle partition 30, the air outlet 1012 is connected to the connecting hole 301, so that the air in the heat dissipation duct 101 can flow to the fan cavity 202 side. When the air inlet 1011 is disposed opposite to the panel 22, the angle between the air inlet direction at the air inlet 1011 and the air outlet direction at the air outlet 1012 is set at 90°.

[0067] like Figure 5 As shown, in some other embodiments of this application, a connecting hole 301 is formed on the second plate segment 32, and the connecting hole 301 is located on the side of the second plate segment 32 adjacent to the first plate segment 31, thereby facilitating the fitting of the electrical control box 10 to the first plate segment 31. When the air inlet 1011 is arranged opposite to the panel 22, the air inlet 1011 and the air outlet 1012 can be arranged opposite to each other in the front-rear direction of the air conditioner outdoor unit 100 to ensure smooth airflow through the heat dissipation duct 101.

[0068] In some other embodiments of this application, the connecting hole 301 is formed in the adjacent area of ​​the first plate segment 31 and the second plate segment 32, and the air outlet 1012 of the electrical control box 10 is correspondingly arranged at the corner near the first plate segment 31 and the second plate segment 32, so as to connect the air outlet 1012 with the connecting hole 301.

[0069] It should be noted that the position of the connecting hole 301 on the partition plate 30 can be designed according to the matching position between the electrical control box 10 and the partition plate 30.

[0070] In some embodiments of this application, the electrical control box 10 includes: a box assembly 11, an electrical control assembly 12, and a heat sink 13.

[0071] The box assembly 11 is mounted on the partition plate 30 on one side of the compressor cavity 201, and the box assembly 11 forms the aforementioned heat dissipation duct 101. The radiator 13 can be used to exchange heat with the electronic control assembly 12, and the electronic control assembly 12 and the radiator 13 are arranged within the heat dissipation duct 101. When air flows through the heat dissipation duct 101, the air can exchange heat with the radiator 13 and the electronic control assembly 12 arranged within the heat dissipation duct 101, thereby carrying the heat from the radiator 13 and the electronic control assembly 12 out of the heat dissipation duct 101 (i.e., transferring it to the fan cavity 202 side), thus achieving heat dissipation and cooling of the electronic control box 10.

[0072] It is understandable that the airflow in the heat dissipation duct 101 is formed by generating negative pressure on one side of the fan cavity 202, so that one end of the box assembly 11 forming the air inlet 1011 can be abutted against the inner wall surface of the panel 22 (i.e. the wall surface facing the compressor cavity 201), so that the air flowing into the inner side of the shell assembly 20 through the second connecting hole 301 can directly enter the heat dissipation duct 101, ensuring the air intake effect of the box assembly 11.

[0073] Reference Figure 9It should be noted that the electronic control assembly 12 may include power devices 1221, capacitive devices (not shown), inductive devices (not shown), and other electronic devices 122. When the electronic control box 10 is in operation, the power devices 1221 (e.g., bridge rectifiers) generate a large amount of heat, while the capacitive and inductive devices generate less heat compared to the power devices 1221. Therefore, the power devices 1221 can be paired with the heat sink 13 to improve the heat dissipation efficiency of the power devices 1221 through heat exchange. Simultaneously, other electronic devices 122 (such as the aforementioned capacitive and inductive devices) can be directly arranged in the heat dissipation duct 101 to carry away heat through the air flowing through the duct 101, thus achieving heat dissipation and cooling.

[0074] In some embodiments of this application, the box assembly 11 includes a box body 111 and a box cover 112. The box body 111 forms a receiving groove that opens to one side in a first direction. The box cover 112 covers the open end of the receiving groove, and the box cover 112 and the box body 111 define a heat dissipation duct 101. When the box assembly 11 is assembled in the outdoor unit 100 of an air conditioner, the aforementioned "first direction" can be the left-right direction of the outdoor unit 100.

[0075] Combination Figure 5 and Figure 9 As shown, when the box assembly 11 is arranged at the partition 30, the box cover 112 is fitted to the partition 30 to improve the assembly reliability between the box assembly 11 and the partition 30, and the box body 111 is open to the side facing the partition 30. The box body 111 and the box cover 112 are connected and fitted together to form the aforementioned heat dissipation duct 101 between them. The electronic control assembly 12 can be arranged within the heat dissipation duct 101, and the extension direction of the heat dissipation duct 101 is parallel to the first plate segment 31 of the partition 30 (i.e., the plate segment structure in the partition 30 that fits and fits with the box cover 112).

[0076] It should be noted that the connection method between the lid 112 and the box body 111 is not specifically limited here. For example, the lid 112 and the box body 111 can be fixedly connected by a snap-fit, or the lid 112 and the box body 111 can be fixedly connected by a connector, etc. At the same time, the cooperation method between the box assembly 11 and the middle partition 30 is not specifically limited, as long as it can satisfy the requirement of fixing the box assembly 11 at the middle partition 30. That is to say, the box assembly 11 can be fixed relative to the middle partition 30 by directly or indirectly connecting to it.

[0077] In a further embodiment of this application, the box assembly 11 is provided with a partition rib 114. The partition rib 114 is used to separate the heat dissipation air duct 101 and form a plurality of sub-air ducts 1013. The plurality of sub-air ducts 1013 are arranged independently of each other. That is to say, the air flowing through any one sub-air duct 1013 can be directly discharged to the side of the fan cavity 202 through the first connecting hole 301, thereby avoiding the air flowing through the sub-air duct 1013 from flowing into other sub-air ducts 1013 and causing a reduction in heat dissipation efficiency.

[0078] The partition rib 114 can be provided on at least one of the cover 112 and the body 111. Figure 8 and Figure 9 As shown, a partition rib 114 is disposed on the housing 111 and extends from the housing 111 toward the cover 112, dividing the housing assembly 11 to form two sub-air ducts 1013. Preferably, the partition rib 114 is arranged laterally to divide the heat dissipation air duct 101 into multiple sub-air ducts 1013 arranged along a third direction (i.e., the vertical direction of the outdoor unit 100), and the ends of the partition rib 114 are adapted to avoid the PCB board 121 arranged vertically in the housing assembly 11.

[0079] Understandably, when multiple sub-channels 1013 are divided at the heat dissipation channel 101, the electrical components 122 in the electronic control assembly 12 can be arranged in separate zones according to heat dissipation requirements. This allows the electrical components 122 to be placed in multiple sub-channels 1013, enabling heat dissipation for each component 122 according to its specific needs, thus improving the heat dissipation efficiency at the electronic control box 10. For example, capacitive and inductive components can be arranged in two separate sub-channels 1013, preventing airflow through the capacitive components from flowing into the sub-channel 1013 containing the inductive components, and vice versa. This ensures that the air cooling actions of the electrical components 122 are independent, thereby improving heat dissipation efficiency.

[0080] Combination Figure 8 and Figure 9 As shown, in a specific embodiment of this application, the heat sink 13 and the power device 1221 are arranged within the same sub-duct 1013. The power device 1221 is adapted to be arranged in close contact with the heat sink 13 so as to further transfer heat outward through the heat sink 13 and improve the heat dissipation effect at the power device 1221.

[0081] In a further embodiment of this application, the heat sink 13 includes a heat sink 132 and a heat sink substrate 131. The heat sink substrate 131 can be used to be attached to an electrical device 122 (such as a power device 1221). The heat sink 132 is disposed on the side of the heat sink substrate 131 away from the electrical device 122. The direction of the heat sink 132 is parallel to the direction of the sub-air duct 1013 (referring to the sub-air duct 1013 where the heat sink 13 is located) to improve the airflow effect when the air in the sub-air duct 1013 flows through the heat sink 13.

[0082] In some embodiments of this application, the electrical control assembly 12 includes a PCB board 121, and electrical components 122 can be arranged on the PCB board 121. The electrical control box 10 also includes a heat sink bracket 14, which is connected to the PCB board 121 and is used to mount a heat sink 13 so that the heat sink 13 is fixed on the PCB board 121 by the heat sink bracket 14.

[0083] Reference Figure 9 The heat sink bracket 14 is arranged around the power device 1221 in the circumferential direction to shield the power device 1221 in the air intake direction of the sub-air duct 1013, preventing the power device 1221 from being exposed, thereby preventing water, dust and other pollutants in the air from adhering to the power device 1221, and playing a protective role for the power device 1221, so as to improve the stability and reliability of the operation of the electrical control box 10.

[0084] In some embodiments of this application, the box assembly 11 is provided with a sliding groove 113 in the heat dissipation duct 101. One end of the sliding groove 113 is connected to the air inlet 1011. The electronic control assembly 12 is slidably engaged with the sliding groove 113 and can slide into or out of the heat dissipation duct 101 through the air inlet 1011.

[0085] like Figure 8 and Figure 9 As shown, one end of the slide groove 113 near the panel 22 is connected to the air inlet 1011, and the PCB board 121 can slide into the box assembly 11 or slide out of the box assembly 11 through the air inlet 1011. Therefore, the PCB board 121 can slide and engage with the box assembly 11, allowing the PCB board 121 to be arranged inside or removed from the box assembly 11 by a pull-out method, thereby reducing the assembly difficulty of the PCB board 121 and the box assembly 11.

[0086] The PCB board 121 serves as the mounting carrier for the electrical components 122 and the heat sink 13. During the assembly of the electrical control box 10, the electrical components 122 can be installed on the PCB board 121 first, and the heat sink 13 can be fixed on the PCB board 121 by the heat sink bracket 14 arranged on the PCB board 121. Then, the electrical control assembly 12 and the heat sink 13 are assembled together on the box assembly 11. The installation method is that the PCB board 121 and the slide groove 113 slide together, which makes the assembly method of the electrical control box 10 simple.

[0087] Understandably, when the control box 10 needs to be repaired or inspected, the control component 12 and the heat sink 13 can be removed from the box component 11 by pulling them out, without having to disassemble the entire control box 10, thus reducing the difficulty of repairing the control box 10.

[0088] Combination Figure 3 and Figure 8 As shown, in some embodiments of the application, one end of the slide 113 is connected to the air inlet 1011 of the heat dissipation duct 101, allowing the electronic control component 12 to be installed from the air inlet 1011 of the housing assembly 11 into the slide 113. The extension direction of the slide 113 is parallel to the extension direction of the heat dissipation duct 101, allowing the electronic control component 12 to be pulled out of or placed into the housing assembly 11 along the direction of the heat dissipation duct 101.

[0089] like Figure 4 As shown, in some embodiments of this application, panel 22 includes a first panel 221 and a second panel 222, which are arranged sequentially and connected along a first direction. The adjacent portions of the first panel 221 and the second panel 222 are connected and engaged with the first segment 31 of the partition 30. That is, the first panel 221 is the component in panel 22 corresponding to the fan cavity 202, and the second panel 222 is the component in panel 22 corresponding to the compressor cavity 201. This facilitates the assembly of the housing assembly 20 with the partition 30 and facilitates the inspection and maintenance of the devices in the fan cavity 202 and the compressor cavity 201.

[0090] Understandably, when it is necessary to disassemble the electrical control box 10, it is only necessary to remove the second panel 222 from the housing body 21 to open the compressor cavity 201 on one side of the panel 22, making it convenient for operators to install and remove the electrical control box 10 from the panel 22 side. Similarly, if it is necessary to inspect and repair the devices (such as fans, heat exchangers, etc.) in the fan cavity 202, removing the first panel 221 will fully expose the devices in the fan cavity 202 from one side of the panel 22, making it convenient for operators to operate.

[0091] The air conditioner outdoor unit 100 according to the embodiments of this application has at least the following advantages:

[0092] (1) The partition plate 30 is provided with a connecting hole 301, and the shell assembly 20 is provided with an air inlet structure 212, so that the air located outside the shell assembly 20 can be directly compressed into the compressor cavity 201 through the air inlet structure 212, and further flow into the heat dissipation duct 101 through the air inlet 1011 of the control box 10. After flowing through the heat dissipation duct 101, the air in the heat dissipation duct 101 is discharged to the side of the fan cavity 202 through the connecting hole 301. Thus, the negative pressure generated on the side of the fan cavity 202 forms an airflow through the control box 10, and the device in the control box 10 is cooled down by air cooling.

[0093] (2) The electrical control box 10 is arranged on one side of the compressor cavity 201 in cooperation with the partition plate 30, and the electrical control box 10 is arranged near the panel 22. When the electrical control box 10 needs to be repaired, the electrical control box 10 can be removed from the front of the air conditioner outdoor unit 100, reducing the difficulty of removing and installing the electrical control box 10.

[0094] (3) During the assembly of the electrical control box 10, the electrical control component 12 is assembled with the box component 11 through the PCB board 121 in a sliding fit, so as to reduce the assembly difficulty of the electrical control box 10.

[0095] According to an embodiment of this application, the air conditioner includes the outdoor unit 100 described above. The advantages of the air conditioner and the outdoor unit 100 are the same, and will not be repeated here.
