[0039] The air conditioner outdoor unit 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0040] like Figure 1 As shown, the air-conditioning outdoor unit 100 according to the embodiment of the utility model includes a shell 1, a middle partition plate 2 and an electric control heat dissipation component 3.

[0041] Specifically, Figure 1 and Figure 2 As shown, combined Figure 3 and Figure 4The middle partition 2 is arranged in the shell 1, and is used to separate the space in the shell 1 into a fan chamber 4 and a compressor chamber 5. The shell 1 is provided with an air inlet and an air outlet connected to the fan chamber 4. The fan chamber 4 is provided with a fan assembly 41 and a heat exchanger 42. The fan assembly 41 is used to drive the airflow to enter from the air inlet and be discharged from the air outlet. The airflow exchanges heat with the heat exchanger 42 during the flow. Among them, the fan assembly 41 includes a driving motor and a wind wheel 411. The wind wheel 411 is connected to the output shaft of the driving motor to drive the wind wheel 411 to rotate and thus drive the airflow to flow. A motor bracket 35 is also provided in the fan chamber 4 to support the driving motor.

[0042] In addition, the compressor chamber 5 has a compressor 51, which is responsible for compressing the refrigerant into high-temperature and high-pressure gas. The compressor chamber 5 is isolated from the external environment, which is conducive to ensuring the operating performance and stability of the compressor 51. The middle partition 2 effectively isolates two different functional areas, which is conducive to isolating and protecting the functions and performances of different components, reducing the interference between the fan chamber 4 and the compressor chamber 5, and ensuring the performance of the fan assembly 41 and the compressor 51, thereby improving the performance stability of the air conditioner outdoor unit 100.

[0043] Among them, the upper end of the middle partition 2 has an installation opening 21, and the electric control heat dissipation component 3 is arranged at the installation opening 21. The upper end of the installation opening 21 is open, which is convenient for installing the electric control heat dissipation component from top to bottom from the upper end of the installation opening 21 to the installation opening 21 of the middle partition 2, providing convenience for assembly and helping to improve the assembly efficiency of the air-conditioning outdoor unit 100.

[0044] Furthermore, the electric control heat dissipation component 3 is connected to the middle partition 2 by fasteners, such as bolts, screws or rivets, etc. The electric control heat dissipation component 3 can be connected to the middle partition 2, which is simple and convenient to assemble, can improve the assembly efficiency of the air-conditioning outdoor unit 100, and can also provide a stable and reliable connection to ensure the stability and reliability of the air-conditioning outdoor unit 100. At the same time, the electric control heat dissipation component 3 and the middle partition 2 can also be detachably connected, which is convenient for maintenance and replacement, thereby reducing the later maintenance cost of the air-conditioning outdoor unit 100.

[0045] Among them, the electric control heat dissipation component 3 is above the middle partition 2 and separates the fan cavity 4 and the compressor cavity 5. The electric control heat dissipation component 3 can be divided into an electric control component and a heat dissipation component. The electric control component can be arranged in the compressor cavity 5, and the compressor cavity 5 is isolated from the external environment, which can ensure the performance and safety of the electric control component. The heat dissipation component can be arranged in the fan cavity 4. The fan component 41 in the fan cavity 4 is conducive to the heat dissipation effect of the heat dissipation component, realizing the air-cooled heat dissipation of the air-conditioning outdoor unit 100, so that the electric control heat dissipation component 3 can effectively dissipate heat while maintaining the normal working state of the electric control component.

[0046] According to the air-conditioning outdoor unit 100 of the embodiment of the utility model, by arranging the middle partition 2 in the housing 1 and dividing the space in the housing 1 into the fan chamber 4 and the compressor chamber 5, the performance stability of the air-conditioning outdoor unit 100 can be improved. By arranging the electric control heat dissipation component 3 at the installation opening 21 at the upper end of the middle partition 2 and connecting it through fasteners, it can provide convenience for assembly, which is conducive to improving the assembly efficiency of the air-conditioning outdoor unit 100. While ensuring the stability and reliability of the air-conditioning outdoor unit 100, the detachable connection between the electric control heat dissipation component 3 and the middle partition 2 can also be realized, which is convenient for maintenance and replacement, thereby reducing the maintenance cost of the air-conditioning outdoor unit 100.

[0047] In some embodiments of the present invention, Figure 1 As shown, combined Figure 2 and Figure 3 , the extension direction of the fasteners used to connect the electric control heat dissipation component 3 and the middle partition 2 is the same. The middle partition 2 is provided with a first bend 25 bent toward the compressor cavity 5 at both ends along the width direction, and the first bend 25 extends along the length direction of the middle partition 2. The electric control heat dissipation component 3 is provided with a second bend 319 bent toward the compressor cavity 5 corresponding to the first bend 25 of the middle partition 2. The first bend 25 and the second bend 319 are provided with a plurality of corresponding mounting holes, and the fasteners pass through the mounting holes on the first bend 25 and the second bend 319 respectively to connect the electric control heat dissipation component 3 and the middle partition 2, and the plurality of fasteners extend in a direction perpendicular to the first bend 25 and the second bend 319. It provides convenience for the connection between the electric control heat dissipation component 3 and the middle partition 2, and the assembly is simple and convenient, which can improve the assembly efficiency of the air conditioner outdoor unit 100.

[0048] In some embodiments of the present invention, Figure 1 As shown, combined Figure 2 and Figure 3 The fan chamber 4 and the compressor chamber 5 are arranged at intervals in the left and right directions of the air-conditioning outdoor unit 100, with a reasonable structure and compact layout, so that the overall length, width and height dimensions of the air-conditioning outdoor unit 100 are moderate. The first bend 25 on the middle partition 2 and the second bend 319 of the electric control heat dissipation component 3 are located on a plane perpendicular to the front-to-back direction, and the fasteners used to connect the electric control heat dissipation component 3 and the middle partition 2 extend in the front-to-back direction, so that the operator can face the rear and pass the fasteners through the mounting holes on the first bend 25 and the second bend 319 respectively to connect the electric control heat dissipation component 3 and the middle partition 2, which reduces the difficulty of assembly or disassembly work, facilitates the operation of the operator, and thus improves the assembly efficiency and assembly quality of the air-conditioning outdoor unit 100.

[0049] In some embodiments of the present invention, Figure 2 , Figure 3 and Figure 8As shown, the upper end of the middle partition 2 has a hanging hole 24, which is located above the mounting opening 21. The upper end of the middle partition 2 is provided with a third baffle 26 bent toward the direction close to the fan chamber 4, and the third baffle 26 extends along the width direction of the middle partition 2. The hanging hole 24 penetrates the third baffle 26 in the thickness direction of the third baffle 26. The upper end of the electric control heat dissipation component 3 has a hook 312 that cooperates with the hanging hole 24. The hook 312 can be inserted into the hanging hole 24, which can play a positioning role, and at the same time, it also realizes the reliable suspension of the electric control heat dissipation component 3 on the middle partition 2, which is easy to install and disassemble, and improves the convenience and operation efficiency of assembly and disassembly. On the other hand, the cooperation of the hook 312 and the hanging hole 24 also provides additional fixed support, which can enhance the stability and reliability of the connection between the electric control heat dissipation component 3 and the middle partition 2, thereby enhancing the structural stability of the air conditioner outdoor unit 100.

[0050] Furthermore, if Figure 6 and Figure 7 As shown, the hook 312 has a first hook portion 3121 and a second hook portion 3122. One end of the first hook portion 3121 is connected to the electric control mounting plate 31, and the other end extends toward the direction close to the fan cavity 4. The second hook portion 3122 is arranged at the end of the first hook portion 3121 close to the fan cavity 4. Preferably, the second hook portion 3122 can be perpendicular to the first hook portion 3121 and extend downward. In addition, the size of the second hook portion 3122 and the size of the hanging hole 24 can match each other so that the second hook portion 3122 can pass through the hanging hole 24. For example, when assembling the electronically controlled heat dissipation component 3 and the middle partition 2, the operator can install the electronically controlled heat dissipation component from the upper end of the middle partition 2 from top to bottom to the installation port 21 of the middle partition 2, so that the second hook portion 3122 extends into the hanging hole 24 and the first hook portion 3121 fits with the third baffle 26. At this time, the electronically controlled heat dissipation component 3 can be mounted on the middle partition 2, which is convenient for the operator to perform subsequent fastener connection operations, thereby reducing the complexity and time cost of the installation process, and thus improving the assembly efficiency of the electronically controlled heat dissipation component 3 and the middle partition 2.

[0051] In some embodiments of the present invention, Figure 2 and Figure 3As shown, the lower edge of the installation opening 21 is provided with a second plug-in 22 extending upward, and the lower end of the electric control heat dissipation component 3 has a second slot 316 that cooperates with the second plug-in 22. When assembling the electric control heat dissipation component 3 and the middle partition 2, the operator can install the electric control heat dissipation component from the upper end of the middle partition 2 to the installation opening 21 of the middle partition 2 from top to bottom, so that the second plug-in 22 of the middle partition 2 passes through the second slot 316 of the electric control heat dissipation component 3. The cooperation between the second plug-in 22 and the second slot 316 can play a positioning and limiting role, making the installation easier, thereby improving the assembly efficiency of the air-conditioning outdoor unit 100. On the other hand, the cooperation between the second plug-in 22 and the second slot 316 can also provide additional connection and fixing support, thereby enhancing the stability of the overall structure of the air-conditioning outdoor unit 100.

[0052] For example, Figure 3 In the example shown, a second baffle 315 bent toward the compressor chamber 5 is provided on the side of the lower end surface of the electronically controlled heat dissipation component 3 close to the compressor chamber 5, and the second baffle 315 extends along the width direction of the electronically controlled heat dissipation component 3. The second slot 316 is an asymmetric through hole penetrating the second baffle 315, and the shape of the second plug-in 22 can match the shape of the second slot 316, thereby playing a positioning and limiting role.

[0053] In some embodiments of the present invention, Figure 2 As shown, the lower edge of the mounting opening 21 has a fixed platform plate 23 that bends and extends toward the compressor chamber 5, which is used to support the electric control heat dissipation component 3. On the one hand, the fixed platform plate 23 provides an additional support platform, which can ensure the stability and reliability of the electric control heat dissipation component 3 at the mounting opening 21, thereby enhancing the stability of the overall structure of the air-conditioning outdoor unit 100. On the other hand, when the operator assembles the electric control heat dissipation component 3 and the middle partition 2, the operator installs the electric control heat dissipation component from top to bottom from the upper end of the middle partition 2 to the mounting opening 21 of the middle partition 2. At this time, the fixed platform plate 23 can provide support and hold the electric control heat dissipation component, which saves the operator more effort and facilitates the operator to perform subsequent operations such as fastener connection, reducing the complexity and time cost during the installation process, thereby improving the assembly efficiency of the electric control heat dissipation component 3 and the middle partition 2.

[0054] Preferably, if Figure 2 In the example shown, a plurality of reinforcing ribs 231 may be provided at the bend of the fixed platform plate 23, and the reinforcing ribs 231 may be formed into grooves, which may enhance the structural strength and supporting force of the fixed platform plate 23, thereby improving the stability and reliability of the electric control heat dissipation assembly 3 at the mounting port 21.

[0055] In some embodiments of the present invention, Figure 4As shown, a downwardly extending positioning rain shield 317 is provided on one side of the lower end surface of the electric control heat dissipation assembly 3 close to the fan cavity 4, and the positioning rain shield 317 is located on the side of the middle partition 2 facing the fan cavity 4. The compressor cavity 5 contains a compressor 51, pipelines, and electric control components in the electric control heat dissipation assembly 3, etc. The positioning rain shield 317 helps prevent rainwater from entering the compressor cavity 5 from the fan cavity 4, and can protect the performance and safe operation of the electric control components and the compressor 51.

[0056] Furthermore, the lower end surface of the electric control heat dissipation component 3 is provided with a fourth baffle 318 bent toward the fan cavity 4, and one end of the fourth baffle 318 close to the fan cavity 4 is connected to the upper end of the positioning rainproof baffle 317. The middle partition 2 is provided with a step structure that can cooperate with the fourth baffle 318 and the positioning rainproof baffle 317. On the one hand, it can provide an additional support platform, thereby enhancing the stability and reliability of the electric control heat dissipation component 3 at the installation port 21, and at the same time, it also provides a positioning function, which can ensure that the electric control heat dissipation component 3 is correctly positioned on the middle partition 2. On the other hand, the step structure on the middle partition 2 cooperates with the fourth baffle 318 and the positioning rainproof baffle 317, which further improves the rainproof effect, thereby protecting the electric control components in the electric control heat dissipation component 3 from moisture intrusion.

[0057] In some embodiments of the present invention, Figure 5 As shown, combined Figure 3 and Figure 4 The electric control heat dissipation assembly 3 includes: an electric control mounting plate 31, an electric control mounting box 32, an electric control board 33 and a radiator 34.

By providing the electric control mounting box 32, it is convenient to install and connect the electric control board 33 and the radiator 34. By providing the electric control mounting plate 31, it is convenient to install and connect the electric control board 33, the radiator 34 and the electric control mounting box 32 to the middle partition 2. Among them, the electric control installation box 32 and the electric control installation plate 31 can be provided with a plurality of matching installation holes, and the electric control installation box 32 can be connected to the electric control installation plate 31 by fasteners. The installation is simple and convenient, which can improve the assembly efficiency of the electric control heat dissipation component 3, and is also easy to disassemble, thereby reducing maintenance costs.

[0058] Furthermore, the electric control board 33 is located on the side of the electric control installation box 32 away from the electric control installation board 31 and is connected to the electric control installation box 32. The electric control board 33 is provided with electronic components and circuits for controlling and adjusting the compressor 51 and the fan assembly 41 in the air-conditioning outdoor unit 100. The electric control board 33 and the electric control installation box 32 can be provided with a plurality of matching mounting holes.

The installation is simple and convenient, which can improve the assembly efficiency of the electric control heat dissipation assembly 3, and is also easy to disassemble, thereby reducing the maintenance cost.

[0059] Furthermore, the heat sink 34 is located on the side of the electric control board 33 facing the electric control installation box 32 and is inserted into the first opening 311. The heat sink 34 is connected to at least one of the electric control installation box 32, the electric control installation board 31 and the electric control board 33. The heat sink 34 is used to conduct and release heat, which can effectively reduce the temperature of the electric control board 33 and other equipment to ensure the performance and normal operation of the electric control board 33 and other equipment. Figure 5 and Figure 6 In the example shown, the radiator 34 is connected to both the electric control installation box 32 and the electric control installation board 31 , but the present invention is not limited thereto. The radiator 34 may be connected only to the electric control installation box 32 or only to the electric control installation board 31 .

[0060] The heat sink 34 can be divided into a heat sink 341 and fins 342. The heat sink 341 is connected to at least one of the electric control installation box 32 and the electric control installation board 31. The heat sink 341 is located on the side of the electric control installation board 31 away from the fan cavity 4.

[0061] It should be noted that the radiator 34 and the electric control board 33 are connected through the electric control installation box 32 or the electric control installation box 32 and the electric control installation board 31, so as to realize the heat exchange between the radiator 34 and the electric control board 33, thereby realizing the heat dissipation of the electric control board 33, thereby ensuring the normal operation of the electric control board 33, and at the same time, the end of the radiator 34 away from the electric control board 33 passes through the first opening 311 to the heat dissipation area, thereby better promoting the heat dissipation of the radiator 34, improving the heat dissipation efficiency of the radiator 34 to the electric control installation box 32, thereby improving the heat dissipation efficiency of the radiator 34 to the electric control board 33, and ensuring the normal operation of the electric control heat dissipation assembly 3.

Compared with the radiator and the electric control mounting box being installed in the air-conditioning outdoor unit separately, the connection process between the radiator 34 and the electric control mounting box 32 can be completed outside the air-conditioning outdoor unit 100 without the need to connect inside the air-conditioning outdoor unit 100, and the radiator 34 and the electric control mounting box 32 can be installed in the air-conditioning outdoor unit 100 at the same time, thereby reducing the difficulty of installation and improving the installation efficiency. In the present application, if Figure 5 and Figure 6 As shown, the lower end of the electric control installation plate 31 has a first baffle 313 bent toward the compressor chamber 5, and the first baffle 313 is provided with a first slot 314, and the lower end of the electric control installation box 32 is provided with a first plug-in 322 matched with the first slot 314. The first slot 314 can be a rectangular through hole penetrating the first baffle 313, and the shape of the first plug-in 322 can match the shape of the first slot 314. When assembling the electric control heat dissipation component 3, the operator can install the electric control installation box 32 from top to bottom to the first opening 311 of the electric control installation plate 31, so that the first plug-in 322 of the electric control installation box 32 passes through the first slot 314 of the electric control installation plate 31, and the cooperation between the first plug-in 322 and the first slot 314 can play a positioning and limiting role, making the installation easier, thereby improving the assembly efficiency of the electric control heat dissipation component 3. On the other hand, the cooperation between the first plug-in 322 and the first slot 314 can also provide additional connection and fixing support, thereby enhancing the stability of the overall structure of the electric control heat dissipation component 3.

[0063] In some embodiments of the present invention, Figure 5 and Figure 6 As shown, the electric control board 33 includes a substrate 332, at least one first electrical component and a plurality of second electrical components, the substrate 332 includes a first side and a second side 3321 opposite to each other, the first side faces the electric control installation box 32, at least one first electrical component is arranged on the substrate 332 and located on the first side, a plurality of second electrical components are arranged on the substrate 332 and located on the second side 3321, and the first electrical component is thermally connected to the radiator 34; wherein, the heat generated by the electrical component with the largest heat generation among the first electrical components is greater than that of the electrical component with the largest heat generation among the second electrical components, or, the heat generated by the electrical component with the highest temperature among the first electrical components is greater than that of the electrical component with the highest temperature among the second electrical components.

[0064] Among them, it should be noted that the heat generated by the electrical component with the smallest heat in the first electrical components is greater than the electrical component with the largest heat in the second electrical components, or the heat generated by the electrical component with the lowest temperature in the first electrical components is greater than the electrical component with the highest temperature in the second electrical components; that is, the electrical components with large heat generation are all arranged on the first side.

[0065] It can be understood that since the first side is toward the electric control installation box 32, that is, the first side is toward the radiator 34, and since the electrical components with high heat generation are all arranged on the first side, it is convenient to transfer the high heat generated on the electric control board 33 to the radiator 34, which can further improve the heat dissipation effect and further ensure that the air conditioner outdoor unit 100 can work normally.

[0066] In some embodiments of the present invention, Figure 5 and Figure 6 As shown, the electric control installation box 32 has a second opening 321 that penetrates the electric control installation box 32, and the heat sink 34 is connected to the electrical components on the electric control board 33 through the second opening 321. The electric control board 33 includes a first electric control part 333 and a second electric control part 334. The projection of the first electric control part 333 on the plane where the electric control installation box 32 is located falls on the electric control installation box 32, and the projection of the second electric control part 334 on the plane where the electric control installation box 32 is located is outside the electric control installation box 32, and the heat sink 34 is connected to the electrical components on the second electric control part 334.

[0067] It is understandable that the radiator 34 is connected to the electrical components on the electric control board 33 through the second opening 321, so that the heat generated by the electrical components when working is transferred to the radiator 34, so that the electrical components can work normally, and the projection of the second electric control part 334 on the plane where the electric control installation box 32 is located falls on the second opening 321, so that the radiator 34 is connected to the electrical components on the second electric control part 334 through the second opening 321, so that the heat dissipation of the electrical components on the second electric control part 334 is facilitated. The projection of the first electric control part 333 on the plane where the electric control installation box 32 is located falls on the electric control installation box 32, so that the electric control installation box 32 can protect and accommodate the electrical components on the first electric control part 333, so that the electrical components on the first electric control part 333 can work normally.

[0068] In some embodiments of the present invention, Figure 6 As shown, the electric control board 33 includes a substrate 332 and electrical components arranged on the substrate 332. The electric control mounting box 32 has a second opening 321 that penetrates the electric control mounting box 32. The electric control heat dissipation assembly 3 also includes: a bracket 35, the bracket 35 is arranged at the second opening 321 and connected to the substrate 332, the electrical components are arranged on the side of the bracket 35 away from the substrate 332, and the radiator 34 is arranged on the side of the electrical components away from the bracket 35.

[0069] It is understandable that the electrical components can be rectifier bridge stacks, diodes, IGBTs, IPM modules, etc. The arrangement of the electrical components, through the connection between the substrate 332 and the bracket 35, can transfer the high heat generated on the electric control board 33 to the radiator 34, which can further improve the heat dissipation efficiency and further ensure that the air conditioner outdoor unit 100 can work normally. The arrangement of the bracket 35 can fix and install the electrical components, improve the installation reliability of the electrical components, and also enable the electrical components to be regularly attached to the surface of the radiator 34, so that the heat dissipation is reliable. In addition, the electrical components have welding pins on one side facing the electric control board 33, and the welding pins are inserted on the electric control board 33. Through the connection between the welding pins and the electric control board 33, the electrical components are normally powered, so that the electrical components can work normally.

[0070] It should be noted that, Figure 5 As shown, when there is no need to set electrical components, the setting of the bracket 35 can be reduced, thereby reducing the number of parts of the electronically controlled heat dissipation component 3 and reducing the cost of the electronically controlled heat dissipation component 3.

[0071] The bracket 35 is provided with a positioning post 351, and the electric control board 33 is provided with a positioning hole 331 that cooperates with the positioning post 351. The positioning hole 331 may be a circular through hole that penetrates the circuit board in the thickness direction of the circuit board, and the positioning post 351 may be a cylinder that extends toward the bracket 35. In the specific assembly process, the electric control board 33 and the bracket 35 may be positioned by inserting the positioning post 351 into the positioning hole 331, which is convenient for subsequent installation, thereby improving the assembly efficiency and assembly quality of the electric control heat dissipation component 3. The center of the positioning post 351 may be provided with a hollow structure that penetrates the positioning post 351 along the thickness direction of the bracket 35, which is convenient for subsequent fixing of the heat dissipation element placed on the other side of the bracket 35.

[0072] Furthermore, the side of the radiator 34 facing the bracket 35 has a boss arranged opposite to the bracket 35, and the boss abuts against the heat dissipation element, ensuring close contact between the radiator 34, the heat dissipation element and the bracket 35, so that the heat dissipation element with a larger heat output can achieve a better heat dissipation effect, so as to maximize the heat dissipation efficiency, thereby ensuring the heat dissipation effect and performance of the electric control board 33. The boss can be provided with a plurality of threaded holes corresponding to the position of the positioning column 351, and the heat dissipation element can be provided with a plurality of through holes corresponding to the position of the positioning column 351. In the specific installation process, the operator can pass fasteners such as bolts through the hollow structure of the positioning column 351 and the through holes on the heat dissipation element, and then screw them into the threaded holes on the boss to fix the heat dissipation element and the radiator 34, so that the heat dissipation element abuts against the radiator 34, which can ensure the heat dissipation effect of the radiator 34 and the heat dissipation element, and also improve the stability of the heat dissipation element.
