[0039] 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.

[0040] The following is for reference. Figures 1-13 The present application describes an air conditioner outdoor unit 100, which is typically located outdoors.

[0041] An air conditioner outdoor unit 100 according to an embodiment of this application includes an electrical control box 10 and a housing assembly 20.

[0042] Combination Figure 8 and Figure 11 As shown, the electronic control box 10 has an electronic control component 11 and a heat sink 12, and the heat sink 12 is used to exchange heat with the electronic control component 11 so as to transfer the heat of the electronic control component 11 to the outside of the electronic control box 10 through the heat sink 12, thereby improving the heat dissipation efficiency of the electronic control component 11 in the electronic control box 10.

[0043] Combination Figure 2 and Figure 3As shown, the shell assembly 20 has a cavity, and a vertically arranged partition 30 is provided in the cavity. The partition 30 separates the cavity and forms a compressor cavity 201 and a fan cavity 202. The partition 30 includes a first plate segment 31 and a second plate segment 32 that are connected along a second direction and are inclined to each other. The adjacent area of ​​the first plate segment 31 and the second plate segment 32 forms a clearance hole 301 that connects the compressor cavity 201 and the fan cavity 202. The electrical control box 10 is installed on one side of the compressor cavity 201, and the radiator 12 is arranged opposite to the clearance hole 301.

[0044] The fan cavity 202 is equipped with a fan, which generates airflow within the fan cavity 202. When the electrical control box 10 is positioned at the clearance hole 301, the airflow in the fan cavity 202 can pass through at least a portion of the electrical control box 10, thereby carrying away heat from the electrical control box 10 and achieving heat dissipation and cooling.

[0045] Specifically, by arranging the electrical control box 10 at the clearance hole 301 and exposing the radiator 12 to the side of the fan cavity 202, the airflow in the fan cavity 202 can flow through the radiator 12, so as to transfer the heat of the electrical control box 10 to the outside of the air conditioner outdoor unit 100 through the air in the fan cavity 202, thereby achieving heat dissipation and cooling of the electrical control box 10.

[0046] When the middle partition 30 is arranged vertically, it can divide the cavity into a horizontally arranged fan cavity 202 and compressor cavity 201. Combined with... Figure 1 As shown, 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. That is, the first segment 31 and the second segment 32 in the partition 30 are arranged sequentially and connected in the front-to-back direction, and the first segment 31 and the second segment 32 are inclined to each other, so that the partition 30 forms a corner at the connection point (i.e., the adjacent area) of the first segment 31 and the second segment 32. At the same time, the clearance hole 301 is formed at the corner of the partition 30, that is, the "adjacent area of ​​the first segment 31 and the second segment 32" mentioned above, so as to facilitate the exposure of the radiator 12.

[0047] Reference Figure 5 , Figure 5 The arrows in the diagram indicate the airflow direction on one side of the fan cavity 202. In the fan cavity 202, air enters from the rear of the housing assembly 20 and is directed towards the panel 22 (i.e., the front side of the housing assembly 20). During airflow in the fan cavity 202, the air can flow through the corner of the partition 30 and exchange heat with the electrical control box 10, transferring the heat from the electrical control box 10 to the outside of the outdoor unit 100 of the air conditioner, thereby cooling the electrical control box 10 through air cooling.

[0048] It should be noted that currently, in the outdoor unit 100 of the air conditioner, the electrical control box 10 is arranged inside the casing of the outdoor unit 100 to control the operating status of the devices in the outdoor unit 100. In related technologies, the electrical control box 10 in the outdoor unit 100 is cooled by components such as low-temperature pipes, which makes the arrangement of the electrical control box 10 in the outdoor unit 100 difficult.

[0049] In this application, the partition plate 30 divides the cavity into a fan cavity 202 and a compressor cavity 201, and a clearance hole 301 is formed on the partition plate 30 to connect the fan cavity 202 and the compressor cavity 201, so that the electrical control box 10 arranged on one side of the compressor cavity 201 is exposed through the clearance hole 301 (i.e., arranged opposite to one side of the compressor cavity 201). The air in the fan cavity 202 can flow through the electrical control box 10 and transfer the heat at the electrical control box 10 to the outside of the shell assembly 20, thereby cooling the electrical control box 10 by air cooling. Furthermore, since the air flow rate and velocity on the fan cavity 202 side are large, the heat dissipation efficiency at the electrical control box 10 can be guaranteed, and the heat dissipation and cooling effect at the electrical control box 10 can be improved.

[0050] In some embodiments of this application, at least a portion of the radiator 12 extends into the fan cavity 202 through the clearance hole 301, so that the air in the fan cavity 202 can fully contact the radiator 12, thereby improving the heat exchange effect between the air in the fan cavity 202 and the radiator 12 and improving the heat dissipation and cooling efficiency of the radiator 12.

[0051] It is understandable that the second plate segment 32 is bent at the connection point with the first plate segment 31, and the electrical control box 10 is arranged near the first plate segment 31 and the second plate segment 32, thereby facilitating the insertion of the electrical control box 10 from the compressor cavity 201 side through the clearance hole 301 into the fan cavity 202 side. (Refer to...) Figure 5 It can be seen that the electrical control box 10 is arranged on the side of the partition plate 30 facing the compressor cavity 201. The second plate segment 32 is bent relative to the first plate segment 31 towards the electrical control box 10. Thus, when the electrical control box 10 is arranged at the position of the first plate segment 31 near the second plate segment 32, the electrical control box 10 can easily extend from the clearance hole 301, so that the electrical control box 10 (e.g., radiator 12) can extend into the fan cavity 202, thereby improving the heat dissipation and cooling effect at the electrical control box 10.

[0052] Combination Figure 3 and Figure 8As shown, in some embodiments of this application, the heat sink 12 includes a heat sink substrate 121 and a plurality of heat sinks 122. The heat sink substrate 121 is used to connect to the electronic control component 11, so that the electronic control component 11 can transfer heat to one side of the heat sink substrate 121. When the electronic control box 10 is installed on the partition plate 30, the plurality of heat sinks 122 are arranged vertically, and the heat sinks 122 are located on the side of the heat sink substrate 121 adjacent to the fan cavity 202, and a horizontally arranged heat dissipation channel is defined between two adjacent heat sinks 122.

[0053] It should be noted that the above-mentioned "horizontally set" means that the air inlet and outlet positions of the heat dissipation channel are formed on both sides of the radiator 12 in the horizontal direction, so that the air supply direction of the heat dissipation channel is roughly horizontal, ensuring the flow effect of the gas when it flows through the radiator 12.

[0054] Further integration Figure 5 As shown, it can be understood that in the outdoor unit 100 of the air conditioner, the air in the fan cavity 202 flows from the back panel side of the housing assembly 20 to the panel 22 side. When the heat dissipation duct at the radiator 12 is horizontally arranged, the air in the fan cavity 202 can smoothly pass through the heat dissipation duct formed by the heat sink 122, improving the air passage effect at the radiator 12 and enhancing the heat exchange effect between the radiator 12 and the air in the fan cavity 202.

[0055] Reference Figure 11 In some embodiments of this application, the electronic control component 11 includes: a PCB board 111 and an electronic component (not shown in the figure). The PCB board 111 is arranged vertically, and the heat sink 12 is disposed on the side of the PCB board 111 opposite to the first board segment 31. The electronic component is also mounted on the PCB board 111, that is, the PCB board 111 is the mounting carrier for the electronic component and the heat sink 12.

[0056] It should be noted that the electrical components include various types such as power devices, capacitive devices, and inductive devices. The arrangement of these components on the PCB board 111 can be designed according to heat dissipation requirements, thus allowing for a zoned arrangement to meet these requirements. For example, power devices generate more heat during the operation of the control box 10, while capacitive and inductive devices generate relatively less heat. In other words, power devices have higher heat dissipation requirements than capacitive and inductive devices. Therefore, power devices can be placed in positions that cooperate with the heat sink 12, allowing them to transfer heat outwards through the heat sink 12, improving heat dissipation efficiency at the power device location. Capacitive and inductive devices (not shown in the figure) can be arranged in other areas of the PCB board 111.

[0057] Combination Figure 3 and Figure 12As shown, in some embodiments of this application, the electrical control box 10 further includes a box assembly 13, which is mounted on the partition plate 30 on one side of the compressor cavity 201. The electrical control assembly 11 is mounted on the box assembly 13, and the heat sink 12 is located on the side of the box assembly 13 adjacent to the second plate segment 32.

[0058] It is understood that the heat sink 12 cooperates with the electronic control component 11 and is connected and fixed on the PCB board 111. The box assembly 13 is the mounting carrier of the electronic control component 11, so the electronic control component 11 can be assembled and fixed together with the heat sink 12 on the box assembly 13. Furthermore, the box assembly 13 cooperates with the middle partition 30 to fix the electronic control component 11 and the heat sink 12 together at the middle partition 30, thereby realizing the assembly of the electronic control box 10 to the middle partition 30.

[0059] Reference Figure 8 As shown, when the radiator 12 and the electronic control component 11 are assembled on the box assembly 13, the radiator 12 is exposed from the box assembly 13, thus exposing the radiator 12 to the outside of the electronic control box 10, so that the air on the side of the fan cavity 202 can fully contact the radiator 12, thereby improving the heat dissipation and cooling effect of the radiator 12.

[0060] like Figure 11 As shown, in a further embodiment of this application, the box assembly 13 includes a box body 131 and a box cover 132. The box body 131 is used to mount the PCB board 111. The box cover 132 is disposed on the box body 131 along a first direction. The box cover 132 and the box body 131 are fastened together to form a mounting cavity. Electrical components can be disposed in the mounting cavity. The heat sink 12 is placed outside the box cover 132 so that the heat sink 12 is exposed in the box assembly 13.

[0061] It should be noted that since the heat sink 12 is arranged on the outside of the cover 132, the heat sink 12 is located outside the mounting cavity. At the same time, "electrical components" include a variety of functional components. The positions of the various functional components in the PCB board 111 can be arranged according to the heat dissipation requirements. For example, power components with high heat dissipation requirements can be arranged outside the mounting cavity and between the heat sink 12 and the PCB board 111 to achieve heat dissipation through the heat sink 12. Other components with relatively lower heat dissipation requirements than power components (such as capacitive components and inductive components) can be arranged in the corresponding areas of the PCB board 111 and the mounting cavity.

[0062] The electrical components arranged in the mounting cavity can be covered by the cover 132 to prevent them from being exposed and contaminated by water, dust and other pollutants, thus providing good protection for the electrical control components 11 and effectively preventing safety problems such as breakdown.

[0063] Combination Figure 12As shown, a clearance structure is formed on the cover 132 to allow the radiator 12 to be exposed from the box assembly 13, so that the radiator 12 can be exposed on the outside of the box assembly 13 and fully contact the air on the side of the fan cavity 202, thereby improving the heat dissipation and cooling effect of the radiator 12.

[0064] Combination Figure 9 and Figure 12 As shown, the heat sink 12 is disposed on the surface of the PCB board 111 facing the cover 132, thereby allowing the electronic control assembly 11 to be arranged on the same side of the PCB board 111. It is understood that among the electrical components arranged on the same side of the PCB board 111, some components (such as power devices) are located within the mounting cavity, while components located outside the mounting cavity can be arranged between the heat sink 12 and the PCB board 111. Therefore, electrical components can be arranged on the same surface of the PCB board 111, thereby reducing the design and manufacturing difficulty of the electronic control assembly 11, eliminating the need for double-sided soldering on the PCB board 111, and ensuring the production efficiency of the electronic control assembly 11.

[0065] It should be noted that in the relevant technology, in order to meet the heat dissipation requirements of the electrical control box, the heat sink and power components of the electrical control box are arranged on the side of the PCB board facing the fan cavity, while other electrical components are arranged on the side facing the compressor cavity. This results in the need for double-sided soldering on the PCB board, which affects the production efficiency of the electrical control components.

[0066] In this application, electrical components can be arranged on the same side of the PCB board 111, thus eliminating the need for double-sided soldering on the PCB board 111, thereby reducing the manufacturing difficulty of the electrical control assembly 11 and helping to improve production efficiency. At the same time, some electrical components (such as power devices) can be arranged between the heat sink 12 and the PCB board 111 to improve the heat dissipation effect at the power devices.

[0067] Combination Figure 11 and Figure 12 As shown, in some embodiments of this application, the electrical control box 10 further includes a heat sink bracket 14, which is mounted on the PCB board 111 and is used to mount the heat sink 12 to fix the heat sink 12 to the PCB board 111.

[0068] The heat sink bracket 14 can be arranged in a ring shape, and the power devices arranged around the heat sink 12 in the circumferential direction can be arranged to shield the power devices in the circumferential direction to prevent contaminants from adhering to the power devices. The ring-shaped heat sink bracket 14 can expose the power devices so that the heat sink 12 (e.g., heat dissipation substrate 121) can be aligned and fitted with the power area to ensure the heat exchange effect between the power devices and the heat sink 12.

[0069] Combination Figure 3 and Figure 6 As shown, in some embodiments of this application, the clearance hole 301 includes a first clearance area 3011 and a second clearance area 3012. The first clearance area 3011 is formed on the first plate segment 31 and is disposed opposite to the heat sink 12 and the cover 132 in a first direction. The second clearance area 3012 is formed on the second plate segment 32 and is disposed opposite to the heat sink 12 in a second direction.

[0070] Further integration Figure 1 and Figure 3 As shown, "first direction" refers to the left-right direction of the outdoor unit 100, and "second direction" refers to the front-back direction of the outdoor unit 100. Therefore, by setting the first clearance area 3011 and the second clearance area 3012, the electrical control box 10 can be fully exposed, so that the airflow in the fan cavity 202 can fully act on the electrical control box 10, thereby improving the heat dissipation and cooling effect at the electrical control box 10.

[0071] Combination Figure 5 and Figure 8 As shown, when the electrical control box 10 is installed at the middle partition 30, the radiator 12 and the box cover 132 are arranged in the front-to-back direction, and the first plate segment 31 is located on the side of the electrical control box 10 opposite to the fan cavity 202. The first clearance area 3011 can expose the electrical control box 10 and the radiator 12, and the radiator 12 is arranged on the side of the box cover 132 near the second plate segment 32. The second clearance area 3012 can expose the radiator 12, so that the radiator 12 can be exposed to the fan cavity 202 side in multiple directions, so that the air on the fan cavity 202 side can fully cooperate with the radiator 12, and improve the heat dissipation and cooling effect of the radiator 12.

[0072] It should be noted that the first avoidance zone 3011 and the second avoidance zone 3012 can be arranged in a connected manner, or the first avoidance zone 3011 and the second avoidance zone 3012 can be arranged in a non-connected manner, as long as the corresponding position of the electrical control box 10 is exposed, no specific limitation is made here.

[0073] like Figure 10 As shown, in some embodiments of this application, the cover 132 has a raised portion 1321, which is raised in a first direction away from the housing 131, and the heat sink 12 is arranged on the side of the raised portion 1321 adjacent to the second plate segment 32 in a second direction. Thus, by providing the raised portion 1321, the accommodating space of the mounting cavity is increased, and the raised portion 1321 can shield the devices in the mounting cavity, that is, separate the heat sink 12 from the devices in the mounting cavity, preventing airflow passing through the heat sink 12 from flowing into the mounting cavity, avoiding contamination of the devices in the mounting cavity, and improving the protection effect on the devices arranged in the mounting cavity.

[0074] Combination Figure 9 and Figure 10 As shown, in some embodiments of this application, the raised portion 1321 is provided with a first ventilation opening 1322 and a second ventilation opening 1323. The first ventilation opening 1322 is provided on the side surface of the raised portion 1321 facing the fan cavity 202, and the first ventilation opening 1322 connects the mounting cavity and the fan cavity 202. The second ventilation opening 1323 is provided on the bottom wall of the raised portion 1321, and the second ventilation opening 1323 connects the mounting cavity and the compressor cavity 201.

[0075] Therefore, the air in the compressor cavity 201 can enter the mounting cavity through the second vent 1323, and the air in the mounting cavity can flow to the fan cavity 202 through the first vent 1322. Thus, the air in the compressor cavity 201 can flow into the fan cavity 202 after passing through the mounting cavity, so as to dissipate heat and cool down the device in the mounting cavity by means of air cooling.

[0076] It should be noted that, within the fan cavity 202, the operation of the fan can create a negative pressure at the first vent 1322, allowing air in the mounting cavity to flow through the first vent 1322 to one side of the fan cavity 202. After mixing with the air in the fan cavity 202, the air is then discharged to the outside of the air conditioner outdoor unit 100. When air in the mounting cavity flows through the first vent 1322 to the fan cavity 202, air in the compressor cavity 201 can flow through the second vent 1323 to the mounting cavity, replenishing the mounting cavity with air. This creates an airflow from the second vent 1323 to the first vent 1322 within the mounting cavity, achieving heat dissipation and cooling of the components within the mounting cavity.

[0077] In a further embodiment of this application, the second vent 1323 is located at the bottom of the cover 132, so that the mounting cavity is open to the downward side, thereby enabling bottom air intake at the mounting cavity. Compared with other directions of air intake into the mounting cavity, bottom air intake can increase the difficulty for contaminants to enter the mounting cavity, thereby protecting the devices in the mounting cavity and reducing the risk of contamination of the devices in the mounting cavity by contaminants.

[0078] like Figure 9 As shown in this application, a louver 1324 is provided at the first ventilation opening 1322 so that the louvers in the louver 1324 can block the first ventilation opening 1322, preventing pollutants in the fan cavity 202 from entering the installation cavity through the first ventilation opening 1322 and causing damage to the electrical control component 11, thereby improving the safety of the electrical control box 10.

[0079] Reference Figure 9As shown, the louver 1324 is provided with multiple louvers, and the multiple louver structures are arranged sequentially, with an air outlet structure formed between two adjacent and spaced-apart louvers. The louvers can be arranged sequentially in a vertical direction and extend downwards at an angle from the first vent 1322 towards the inner side of the mounting cavity, so as to block the first vent 1322. It should be noted that the specific arrangement of the louvers in the cover 132 is not limited to this, and is not specifically limited here.

[0080] Combination Figure 3 and Figure 11 As shown, in some embodiments of this application, the PCB board 111 is arranged parallel to the first board segment 31, thereby arranging the PCB board 111 along a third direction. Here, the "third direction" refers to the vertical direction of the air conditioner outdoor unit.

[0081] In some other embodiments of this application, the PCB board 111 and the first board segment 31 are arranged at an angle, and the angle between the PCB board 111 and the first board segment 31 is smaller than the angle between the first board segment 31 and the second board segment 32, thereby facilitating the corresponding arrangement of the electrical control box 10 and the partition plate 30.

[0082] like Figure 4 As shown, in some embodiments of this application, the housing assembly 20 includes a housing body 21 and a panel 22. The housing body 21 is open to one side in a second direction (the front side of the air conditioner outdoor unit 100). The panel 22 is detachably mounted on the open side of the housing body 21, and the panel 22 and the housing body 21 define a cavity. The electrical control box 10 is connected to the side of the partition 30 adjacent to the panel 22. Thus, the electrical control box 10 can be disassembled and assembled from the panel 22 side of the air conditioner outdoor unit 100.

[0083] When the outdoor unit 100 of the air conditioner is placed in an outdoor environment, the panel 22 is usually arranged facing outwards (i.e., the side without obstruction or with less obstruction) to ensure the air outlet effect on the fan cavity 202 side. Therefore, when it is necessary to inspect or repair the equipment in the outdoor unit 100, the panel 22 can be removed from the housing 21, allowing operators to inspect or repair the equipment, especially the electrical control box 10, from the front of the outdoor unit 100, reducing the difficulty of inspection and repair of the outdoor unit 100.

[0084] It should be noted that in the relevant technology, the outdoor unit 100 of the air conditioner is 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 repair the electrical control box 10 in the outdoor unit 100, the electrical control box 10 is usually removed by disassembling the top cover of the casing. However, in the pigeon coop installation scenario, this operation is quite difficult.

[0085] In this application, the electrical control box 10 is arranged on the partition 30, and the electrical control box 10 is located on the side of the partition 30 adjacent to the panel 22. When the electrical control box 10 needs to be inspected or repaired, the panel 22 can be removed to expose the electrical control box 10, making it easy for operators to remove the electrical control box 10, thereby reducing the difficulty of disassembling and assembling the electrical control box 10 in the air conditioner outdoor unit 100.

[0086] 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.

[0087] 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.

[0088] like Figure 4 As shown, in some embodiments of this application, the shell body 21 includes a top cover 211, and a connection structure that mates with the panel 22 can be formed at the top cover 211. The top of the panel 22 can mate with the connection structure so that the panel 22 and the top cover 211 are fixedly connected.

[0089] The air conditioner outdoor unit 100 according to the embodiments of this application has at least the following advantages:

[0090] (1) The electrical control box 10 is arranged on the middle partition 30 from the side of the compressor cavity 201, and the middle partition 30 has a clearance hole 301 for exposing the electrical control box 10, so that the radiator 12 and the box cover 132 in the electrical control box 10 can be arranged opposite to the side of the fan cavity 202, so that the airflow in the fan cavity 202 can flow through the radiator 12 to improve the heat dissipation efficiency of the radiator 12.

[0091] (2) The fan cavity 202 can form a negative pressure at the first ventilation port 1322 of the cover 132, so that the airflow in the compressor cavity 201 can flow into the fan cavity 202 side after passing through the installation cavity formed by the box assembly 13. The air flowing through the installation cavity transfers heat to the fan cavity 202 side and discharges it, thereby improving the heat dissipation effect at the electrical control box 10.

[0092] (3) In the box assembly 13, the air intake method of the mounting cavity is bottom air intake, which can reduce the risk of the device in the mounting cavity being contaminated and damaged. Furthermore, a louver 1324 is provided at the first vent 1322 to prevent contaminants on the side of the fan cavity 202 from entering the mounting cavity through the first vent 1322, thereby improving the safety and reliability of the electrical control box 10.
