For example, the first fastener 34 can be a screw.

[0048] At the same time, the setting of the opening 311 allows the radiator 33 to be better connected to the electronic control component 32, thereby improving the heat exchange efficiency between the radiator 33 and the electronic control component 32, improving the heat dissipation efficiency of the radiator 33 to the electronic control component 32, and ensuring the normal operation of the electronic control heat dissipation assembly 3.

[0049] In a specific example, see the attached Figure 7 As shown, combined with reference Figure 6 The radiator 33 has a through hole 336, and the electric control mounting plate 31 has a mounting hole 317. The first fastener 34 can pass through the electric control component 32, the radiator 33 and the electric control mounting plate 31 in sequence, and finally be fixed on the electric control mounting plate 31, thereby fastening the electric control component 32, the radiator 33 and the electric control mounting plate 31 together.

[0050] According to the electric control heat dissipation assembly 3 of the embodiment of the utility model, the electric control heat dissipation assembly 3 includes an electric control mounting plate 31, an electric control component 32 and a radiator 33. The electric control mounting plate 31 has an opening 311. The electric control component 32 is arranged on the electric control mounting plate 31, and at least a part of the electric control component 32 is opposite to the opening 311. The radiator 33 is arranged on the electric control component 32 and the electric control mounting plate 31, and a part of the radiator 33 is penetrated into the opening 311. The electric control mounting plate 31, the radiator 33 and the electric control component 32 are penetrated and connected in sequence by the first fastener 34, which can fasten the electric control mounting plate 31 and the radiator 33 together, improve the close fit between the electric control mounting plate 31 and the radiator 33, thereby forming effective grounding continuity, avoiding the existence of a small gap between the electric control mounting plate 31 and the radiator 33, preventing the occurrence of high-voltage arcs, reducing the safety hazards of the electric control heat dissipation assembly 3, and improving the safety and reliability of the electric control heat dissipation assembly 3.

[0051] In some embodiments of the present invention, refer to the attached Figure 5As shown, there are multiple first fasteners 34, and the multiple first fasteners 34 are arranged at intervals in the circumferential direction of the opening 311. The multiple first fasteners 34 spaced apart are used to penetrate the electric control mounting plate 31, the radiator 33 and the electric control component 32, so that the electric control mounting plate 31 and the radiator 33 can be fastened together from multiple spaced apart locations, further improving the close fit between the electric control mounting plate 31 and the radiator 33, avoiding a small gap between the electric control mounting plate 31 and the radiator 33, preventing the occurrence of high-voltage arcs, reducing the safety hazards of the electric control heat dissipation component 3, and improving the safety and reliability of the electric control heat dissipation component 3. For example, the number of the first fasteners 34 can be two, three, four or five, so that the electric control mounting plate 31 and the radiator 33 can be better fastened together.

[0052] In a specific example, see the attached Figure 5 As shown, there are two first fasteners 34, and the two first fasteners 34 are spaced apart in the width direction of the electric control heat dissipation component 3, so as to fasten the electric control mounting plate 31 and the radiator 33 together from two places, thereby improving the close fit between the electric control mounting plate 31 and the radiator 33, avoiding a small gap between the electric control mounting plate 31 and the radiator 33, preventing the occurrence of high-voltage arcs, reducing the safety hazards of the electric control heat dissipation component 3, and improving the safety and reliability of the electric control heat dissipation component 3.

[0053] In some embodiments of the present invention, refer to the attached Figure 2 As shown, the electric control component 32 includes an electric control installation box 321 and an electric control board 322. The electric control installation box 321 is arranged on one side of the electric control installation board 31. The radiator 33 is arranged on the electric control installation box 321. The electric control installation box 321 is opposite to the opening 311 and connected to the electric control installation board 31. By setting the electric control installation box 321, it is convenient to install and connect the electric control board 322 and the radiator 33. Among them, the electronic components and circuits used for control and regulation are arranged on the electric control board 322, which are used to control and regulate the compressor and the fan 111 in the air conditioner outdoor unit 100.

[0054] Further, see Attachment Figure 2 As shown, the electric control mounting plate 31, the radiator 33 and the electric control mounting box 321 are sequentially penetrated and connected by the first fastener 34. The first fastener 34 passes through the electric control mounting plate 31, the radiator 33 and the electric control mounting box 321 in sequence, so that the electric control mounting plate 31 and the radiator 33 can be fastened together, and the close fit between the electric control mounting plate 31 and the radiator 33 is improved, thereby forming effective grounding continuity, avoiding the existence of a small gap between the electric control mounting plate 31 and the radiator 33, preventing the occurrence of high-voltage arcs, reducing the safety hazards of the electric control heat dissipation component 3, and improving the safety and reliability of the electric control heat dissipation component 3.

[0055] Further, see Attachment Figure 2As shown, the electric control board 322 is located on the side of the electric control installation box 321 away from the electric control installation plate 31 and is connected to the electric control installation box 321. The electric control board 322 is connected to the electric control installation plate 31 and the radiator 33 through the electric control installation box 321, and can exchange heat with the radiator 33, thereby improving the heat dissipation efficiency of the radiator 33 to the electric control board 322 and ensuring the normal operation of the electric control heat dissipation component 3.

[0056] It should be noted that Figure 2 For example, the assembly process of the electronically controlled heat dissipation component 3 is described as follows: first, the electronically controlled board 322, the radiator 33 and the electronically controlled mounting box 321 are connected, the radiator 33 is inserted into the opening 311, and then the radiator 33 is connected to the electronically controlled mounting box 321 and the electronically controlled mounting board 31 to form the electronically controlled heat dissipation component 3.

[0057] Furthermore, if Fig.11 As shown, the electric control board 322 includes a substrate 3321, at least one first electrical component and a plurality of second electrical components, the substrate 3321 includes a first side and a second side opposite to each other, the first side faces the electric control installation box 321, at least one first electrical component is arranged on the substrate 3321 and is located on the first side, a plurality of second electrical components are arranged on the substrate 3321 and are located on the second side, and the first electrical component is thermally connected to the radiator 33; 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.

[0058] 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.

[0059] It can be understood that since the first side is toward the electric control installation box 321, that is, the first side is toward the radiator 33, 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 322 to the radiator 33, which can further improve the heat dissipation effect and further ensure that the air-conditioning outdoor unit 100 can work normally.

[0060] In this application, if Fig.11As shown, the electric control installation box 321 has a second opening 3211 that penetrates the electric control installation box 321, and the heat sink 33 is connected to the electrical components on the electric control board 322 through the second opening 3211. The electric control board 322 includes a first electric control part 3222 and a second electric control part 3223. The projection of the first electric control part 3222 on the plane where the electric control installation box 321 is located falls on the electric control installation box 321, and the projection of the second electric control part 3223 on the plane where the electric control installation box 321 is located is outside the electric control installation box 321. The heat sink 33 is connected to the electrical components on the second electric control part 3223.

[0061] It can be understood that the radiator 33 is connected to the electrical components on the electric control board 322 through the second opening 3211, so that the heat generated by the electrical components when working is transferred to the radiator 33, so that the electrical components can work normally, and the projection of the second electric control part 3223 on the plane where the electric control installation box 321 is located falls on the second opening 3211, so that the radiator 33 is connected to the electrical components on the second electric control part 3223 through the second opening 3211, so that the heat dissipation of the electrical components on the second electric control part 3223 is facilitated. The projection of the first electric control part 3222 on the plane where the electric control installation box 321 is located falls on the electric control installation box 321, so that the electric control installation box 321 can protect and accommodate the electrical components on the first electric control part 3222, so that the electrical components on the first electric control part 3222 can work normally.

[0062] In a further embodiment of the present invention, refer to the attached Figure 5 As shown, the electric control board 322 and the electric control installation box 321 are connected by the second fastener 35, which facilitates the assembly of the electric control board 322 and the electric control installation box 321 and improves the reliability and stability of the connection between the electric control board 322 and the electric control installation box 321. For example, the second fastener 35 can be a screw.

[0063] In a further embodiment of the present invention, refer to the attached Figure 5 As shown, the electric control installation box 321 and the electric control installation board 31 are connected by the third fastener 36, which facilitates the assembly of the electric control installation box 321 and the electric control installation board 31 and improves the reliability and stability of the connection between the electric control installation box 321 and the electric control installation board 31. For example, the third fastener 36 can be a screw.

[0064] In a further embodiment of the present invention, the radiator 33 and the electric control installation box 321 are connected by a fourth fastener, which facilitates the assembly of the radiator 33 and the electric control installation box 321 and improves the reliability and stability of the connection between the radiator 33 and the electric control installation box 321. For example, the fourth fastener may be a screw.

[0065] The outdoor air conditioner 10 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0066] like Figure 1 As shown, the air-conditioning outdoor unit 10 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.

[0067] Specifically, refer to the attached Figure 1 As shown, the housing 1 can protect the internal structure of the air-conditioning outdoor unit 10 to prevent the internal structure of the air-conditioning outdoor unit 10 from being exposed and damaged, which is beneficial to extending the service life of the air-conditioning outdoor unit 10 and has a better appearance.

[0068] Further, see Attachment Figure 1 As shown, the middle partition 2 is arranged in the shell 1, and is used to divide the space in the shell 1 into a fan chamber 11 and a compressor chamber 12, wherein the fan 111 is arranged in the fan chamber 11, and the compressor is arranged in the compressor chamber 12. The fan 111 and the compressor are separated by the middle partition 2 to avoid working interference between the fan 111 and the compressor. The middle partition 2 can be made of metal to ensure that it has sufficient strength and durability.

[0069] Further, see Appendix Figure 1 As shown, the upper end of the middle partition 2 has an installation opening 21, the electric control heat dissipation component 3 is arranged at the installation opening 21, and the radiator 33 is passed through the installation opening 21. The size and shape of the installation opening 21 must match the electric control heat dissipation component 3 to ensure the stability and tightness of the assembly.

[0070] It is understandable that if Figure 1 As shown, the mounting opening 21 is along the thickness direction of the middle partition plate 2 (see attached Figure 1 The two ends of the mounting opening 21 are open, and the upper end of the mounting opening 21 has an open opening, so that the electric control heat dissipation component 3 can be placed vertically by gravity without turning over the electric control heat dissipation component 3, which simplifies the installation operation of the electric control heat dissipation component 3. At the same time, the wall surface at the mounting opening 21 can limit the downward movement of the electric control heat dissipation component 3, and can also limit the electric control heat dissipation component 3 along the width direction of the middle partition plate 2 (refer to the attached Figure 1 k direction as shown in the figure), and then move the two ends of the middle partition plate 2 in the width direction to the width direction of the electric control heat dissipation component 3 (refer to the attached Figure 1 The two ends of the electric control heat dissipation component 3 are connected in the k direction as shown, thereby limiting the upward movement of the electric control heat dissipation component 3, thereby realizing the connection and fixation between the electric control heat dissipation component 3 and the middle partition 2. Compared with the prior art in which the electric control heat dissipation component is turned upside down on the middle partition and the electric control heat dissipation component is connected to the upper end of the middle partition and the two ends in the width direction of the middle partition, the connection points between the electric control heat dissipation component 3 and the upper end of the middle partition 2 can be reduced, thereby making it simple to disassemble and assemble the electric control heat dissipation component 3 and facilitate the maintenance of the electric control heat dissipation component 3.

[0071] It should be noted that the radiator 33 and the electronic control component 32 are connected through the electronic control mounting plate 31 to achieve heat exchange between the radiator 33 and the electronic control component 32, thereby achieving heat dissipation of the electronic control component 32 and ensuring the normal operation of the electronic control component 32. Since a fan 111 is provided in the fan chamber 11, the rotation of the fan 111 can increase the air flow rate in the fan chamber 11. The radiator 33 is provided on the side of the electronic control component 32 facing the fan chamber 11, which can facilitate better heat dissipation of the radiator 33 and improve the heat dissipation efficiency of the electronic control heat dissipation component 3, so that the air-conditioning outdoor unit 10 can work better and improve the safety and reliability of the air-conditioning outdoor unit 10.

[0072] Optionally, the electric control mounting plate 31 and the middle partition plate 2 can be connected by fasteners, which can facilitate the assembly of the electric control mounting plate 31 and the middle partition plate 2, improve the reliability and stability of the connection between the electric control mounting plate 31 and the middle partition plate 2, and facilitate the assembly and disassembly of the electric control heat dissipation component 3, reduce the assembly difficulty and maintenance difficulty of the air-conditioning outdoor unit 10, improve the assembly efficiency and maintenance efficiency of the air-conditioning outdoor unit 10, and reduce the production cost and maintenance cost. For example, the fastener can be a screw.

[0073] According to the housing outdoor unit 10 of the embodiment of the utility model, the above-mentioned electric control heat dissipation assembly 3 is provided, and the electric control heat dissipation assembly 3 includes an electric control mounting plate 31, an electric control component 32 and a radiator 33.

The radiator 33 is arranged on the electric control component 32 and the electric control mounting plate 31, and a part of the radiator 33 is penetrated into the opening 311. The electric control mounting plate 31, the radiator 33 and the electric control component 32 are penetrated and connected in sequence by the first fastener 34, which can fasten the electric control mounting plate 31 and the radiator 33 together, improve the close fit between the electric control mounting plate 31 and the radiator 33, thereby forming effective grounding continuity, avoiding a small gap between the electric control mounting plate 31 and the radiator 33, preventing the occurrence of high-voltage arcs, reducing the safety hazards of the electric control heat dissipation assembly 3, and improving the safety and reliability of the electric control heat dissipation assembly 3.

The upper end of the main body 314 has a vent 3141, and the vent 3141 is located above the opening 311. The air duct box 315 is arranged on the main body 314 and is communicated with the vent 3141. The air duct box 315 is open on one side and the lower side of the main body 314. The air duct box 315 and the main body 314 jointly define an air inlet channel 316 communicated with the vent 3141. The air inlet channel 316 connects the fan chamber 11 and the compressor chamber 12. The flow of airflow in the air inlet channel 316 can improve the heat exchange between the electric control component 32 and the airflow, improve the heat dissipation efficiency and heat dissipation effect of the electric control heat dissipation component 3, so that the air-conditioning outdoor unit 10 can work better, and improve the safety and reliability of the air-conditioning outdoor unit 10. It can be understood that the airflow in the compressor chamber 12 can flow into the air inlet channel 316 through the vent 3141, and then flow out of the air inlet channel 316 through the lower open port of the air duct box 315. The airflow in the air inlet channel 316 can exchange heat with the electronically controlled heat dissipation component 3, thereby achieving a heat dissipation effect on the electronically controlled heat dissipation component 3.

[0075] It should be noted that the provision of the air duct box 315 can shield the electronic control component 32 from rain, and to a certain extent prevent rainwater from entering the compressor chamber 12, thereby protecting the electronic control heat dissipation component 3 and improving the safety and reliability of the air conditioner outdoor unit 10.

[0076] In a further embodiment of the present invention, the air duct box 315 is connected to the body 314 by a fastener, which facilitates the assembly of the air duct box 315 and the body 314 and improves the reliability and stability of the connection between the air duct box 315 and the body 314. For example, the fastener may be a screw.

[0077] In other embodiments of the utility model, the air duct box 315 and the main body 314 are provided with matching first positioning parts, the air duct box 315 and the main body 314 are positioned and connected by the first positioning parts, and the air duct box 315 and the main body 314 are welded and connected, which can effectively reduce the risk of rainwater infiltration from the connection between the air duct box 315 and the main body 314, protect the electronically controlled heat dissipation component 3, and improve the safety and reliability of the air-conditioning outdoor unit 10.

[0078] In some embodiments of the present invention, refer to the attached Figure 2 and attached Figure 8As shown, the radiator 33 includes a heat sink 331 and fins 332. The heat sink 331 is located on the side of the electric control mounting plate 31 away from the fan cavity 11. The electric control mounting plate 31, the heat sink 331 and the electric control component 32 are sequentially connected through the first fastener 34. The fins 332 are located on the side of the heat sink 331 away from the electric control component 32, and the fins 332 are penetrated in the opening 311. It can be understood that the fan 111 is arranged in the fan cavity 11, and the air flow rate in the fan cavity 11 is fast. The fins 332 are arranged on the side of the heat sink 331 facing the fan cavity 11 to improve the heat dissipation efficiency of the radiator 33. The heat sink 331 is located on the side of the electric control mounting plate 31 away from the fan cavity 11, which can facilitate the connection between the heat sink 331 and the electric control component 32, thereby facilitating heat exchange with the electric control component 32, thereby improving the heat dissipation efficiency of the electric control component 32.

[0079] At the same time, the fins 332 are arranged in the opening 311, and the heat sink 331 is arranged on the side of the opening 311 facing the compressor chamber 12, and the heat sink 331 is arranged in the fan chamber 11 and the compressor chamber 12 (refer to the attached Figure 1 The projection surface of the heat sink 331 in the j direction shown in the figure completely covers the opening 311, thereby limiting the movement of the heat sink 331 toward the fan chamber 11, thereby limiting the movement of the radiator 33 toward the fan chamber 11, thereby improving the installation reliability of the radiator 33. In addition, since the projection surface of the heat sink 331 in the arrangement direction of the fan chamber 11 and the compressor chamber 12 completely covers the opening 311, it can block rainwater, thereby protecting some internal circuit structures in the compressor chamber 12, such as the electric control component 32, from being disturbed by rainwater, thereby improving the waterproof performance.

[0080] In a further embodiment of the present invention, refer to the attached Fig. 9 and attached Fig.10 As shown in the attached reference Figure 8 , the electric control installation plate 31 is in the width direction of the opening 311 (refer to the attached Figure 3 The first flange 312 is bent and extended toward the compressor chamber 12 on both sides of the first flange 312 along the up and down direction (as shown in the k direction). Figure 2 The heat sink 331 extends away from the surface width direction of the electric control component 32 (see the attached Figure 8 The first grooves 333 cooperating with the first flange 312 are provided on both sides of the first flange 312 (in the k direction shown in FIG. 1 ). It can be understood that the cooperation between the first flange 312 and the first groove 333 can limit the heat sink 33 along the width direction of the electric control mounting plate 31 (see FIG. 1 ). Fig. 9k direction as shown), thereby improving the installation reliability of the radiator 33. In addition, the first groove 333 can play a role in drainage. When rainwater falls on the heat sink 331, the rainwater can flow along the first groove 333 to the bottom of the fan cavity 11, avoiding the rainwater from flowing to the circuit structure such as the electronic control component 32. At the same time, the groove wall of the first groove 333 can prevent the rainwater from flowing to other positions, further improving the waterproof performance.

[0081] In a further embodiment of the present invention, refer to the attached Figure 6 and attached Figure 7 As shown, the electric control mounting plate 31 is provided with a second flange 313 bent and extending toward the compressor chamber 12 at the lower edge of the opening 311, and the second flange 313 extends along the width direction of the opening 311 (see the attached Figure 3 The heat sink 331 extends in the k direction as shown, and a second groove 334 cooperating with the second flange 313 is provided on the surface of the heat sink 331 away from the electric control component 32. Therefore, through the cooperation between the second flange 313 and the second groove 334, the downward movement of the heat sink 33 can be further limited, thereby improving the installation reliability of the heat sink 33.

[0082] In addition, the two edges of the opening 311 in the width direction are provided with first flanges 312 bent and extended toward the compressor cavity 12, and the first flanges 312 extend in the up and down directions. The two sides of the surface width direction of the heat sink 331 away from the electronic control component 32 are provided with first grooves 333 cooperating with the first flanges 312, and the second grooves 334 are connected to the first grooves 333, and the second grooves 334 play a role in drainage. When rainwater falls on the heat sink 331, the rainwater can flow along the first grooves 333 to the second grooves 334 and flow toward the bottom of the fan cavity 11, thereby preventing rainwater from flowing to the circuit structure such as the electronic control component 32, thereby improving the waterproof performance.

[0083] In a further embodiment of the present invention, refer to the attached Figure 7 As shown, in the bottom-up direction (such as Figure 6 As shown in FIG. 1 , the second flange 313 is inclined toward the compressor cavity 12. It can be understood that the second flange 313 is located in the second groove 334. When rainwater flows into the second groove 334, since the second flange 313 is inclined toward the compressor cavity 12 in the bottom-up direction, the rainwater can flow to the bottom of the fan cavity 11 along the second flange 313, thereby avoiding the retention of rainwater in the second groove 334 and on the second flange 313, further reducing the probability of rainwater flowing to the circuit structure such as the electric control component 32, thereby improving the waterproof performance.

[0084] In addition, the provision of the first groove 333, the second groove 334 and the second flange 313 realizes waterproofing and drainage of the compressor chamber 12 of the air-conditioning outdoor unit 10. Compared with the prior art of providing a sealing ring or sponge between the electronic control mounting plate and the radiator to achieve waterproofing, the provision of sealing rings or sponges is reduced, materials are reduced, and the assembly process of the air-conditioning outdoor unit 10 is reduced, thereby reducing the cost of the air-conditioning outdoor unit 10. At the same time, the risk of aging and failure of the sealing ring or sponge is reduced, further improving the reliability of waterproofing.

[0085] In a further embodiment of the present invention, refer to the attached Figure 7 As shown, a third groove 335 is provided at the lower end of the surface of the heat sink 331 away from the electric control component 32, the third groove 335 is located above the second groove 334, the lower end of the third groove 335 is open and communicates with the second groove 334, the depth of the second groove 334 is greater than the depth of the third groove 335, and the second groove 334 and the third groove 335 form a step. It can be understood that the setting of the step makes it easier for rainwater to enter the second groove 334, thereby further improving the drainage efficiency, reducing the retention of rainwater in the heat sink 331, thereby reducing the infiltration of rainwater into the circuit structure such as the electric control component 32, and thus improving the waterproof performance.

[0086] In a further embodiment of the present invention, refer to the attached Figure 7 As shown, in the bottom-up direction, the lower side of the second groove 334 is inclined toward the compressor chamber 12. Thus, the retention of rainwater in the second groove 334 can be further avoided, and the penetration of rainwater into the circuit structure such as the electric control component 32 can be reduced, thereby further improving the waterproof performance.

[0087] In a further embodiment of the present invention, refer to the attached Figure 8 As shown, the fins 332 include a plurality of fins extending along the width direction of the heat sink 331 (see FIG. Figure 8 The fins 332 are spaced apart from each other in the k direction (shown in the figure), and each fin 332 extends in the up-down direction, so that the contact area with the air can be increased by the fins 332, thereby improving the heat dissipation efficiency, further promoting the heat dissipation of the electric control component 32, so that the electric control component 32 can work normally. At the same time, the fins 332 are spaced apart to form a plurality of drainage channels. When rain falls on the heat dissipation plate 331, it can flow from top to bottom along the plurality of drainage channels to the bottom of the fan chamber 11, thereby improving the drainage efficiency and reducing the retention of rainwater on the heat dissipation plate 331.

It can be understood that the height of the fins 332 in the second group of fins 3322 is high, so that the heat exchange area of ​​the second group of fins 3322 is large, which is conducive to improving the heat dissipation efficiency of the radiator 33, wherein, since the first group of fins 3321 is arranged closer to the fan 111 relative to the second group of fins 3322 in the width direction of the heat dissipation plate 331, and the height of the fins 332 in the first group of fins 3321 is low, the installation interference between the first group of fins 3321 and the fan 111 can be avoided, and the normal rotation of the fan 111 during the operation of the air conditioner outdoor unit 10 is guaranteed.

[0089] Therefore, through the reasonable layout of the first group of fins 3321 and the second group of fins 3322, and the height of the fins 332 in the first group of fins 3321 is less than the height of the fins 332 in the second group of fins 3322, the heat dissipation efficiency of the radiator 33 is guaranteed and the installation interference between the first group of fins 3321 and the fan 111 can be avoided.
