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.

In the present application, as shown in FIG. 2 , 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 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.

In addition, taking Figures 1 and 2 as an example, the assembly process of the electronically controlled heat dissipation component 3 is described: 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, and finally, the electronically controlled heat dissipation component 3 is installed in the mounting port 21 of the middle partition 2 to complete the assembly.

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 heat sink 33, and 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.

At the same time, the fin 332 passes through the opening 311 and extends into the fan cavity 11, and the heat sink 331 is arranged on the side of the opening 311 facing the compressor cavity 12, and the projection surface of the heat sink 331 in the arrangement direction of the fan cavity 11 and the compressor cavity 12 (refer to the j direction shown in FIG. 1) completely covers the opening 311, thereby limiting the movement of the heat sink 331 toward the fan cavity 11, thereby limiting the movement of the radiator 33 toward the fan cavity 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 cavity 11 and the compressor cavity 12 completely covers the opening 311, it can block rainwater, thereby protecting some internal structural circuit structures in the compressor cavity 12, such as the electric control component 32, from being disturbed by rainwater, thereby improving waterproofness.

In addition, since the air inlet channel 316 is connected to the fan cavity 11 and the compressor cavity 12 respectively, the heat dissipation effect of the electronically controlled component 32 located in the compressor cavity 12 is improved by the flow of the airflow in the air inlet channel 316, thereby improving the heat dissipation efficiency of the electronically controlled heat dissipation component 3.

When the air-conditioning outdoor unit 10 is operating in rainy weather, the fan 111 rotates, and part of the rainwater will be scattered on the radiator 33 through the fan cavity 11. By covering the upper end of the fin 332 with the air duct box 315, the rainwater can be reduced from being scattered on the upper end of the fin 332, and the possibility of rainwater entering the compressor cavity 12 can be reduced, thereby protecting the performance of the electronic control component 32 located in the compressor cavity 12, ensuring its safe operation, and improving the reliability of the electronic control heat dissipation component 3.

At the same time, the heat sink formed by two adjacent fins 332 can also be used as a drainage channel, when rainwater falls on the heat sink 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 sink 331.

Furthermore, the fin 332 is located below the air outlet of the air inlet channel 316, which can reduce the difficulty of assembling the electric control heat dissipation component 3, improve the assembly efficiency of the electric control heat dissipation component 3, and facilitate the assembly of the air conditioner outdoor unit 10. Further, referring to Figures 16 and 17, the fin 332 includes a plurality of fins spaced apart along the width direction of the heat dissipation plate 331, each fin 332 extends in the up-down direction, and the extension direction of the heat dissipation groove formed by two adjacent fins 332 is substantially consistent with the air outlet direction at the air outlet of the air inlet channel 316, thereby, the plurality of fins 332 can increase the contact area with the air, facilitate the circulation of air flow, 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 heat dissipation groove formed by two adjacent fins 332 can also be used as a drainage channel. When rainwater 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.

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 electric control component 32. At the same time, the groove wall of the first groove 333 can prevent rainwater from flowing to other locations, further improving the waterproof performance.

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 direction from bottom to top, the rainwater can flow along the second flange 313 to the bottom of the fan cavity 11, thereby avoiding the retention of rainwater in the second groove 334 and the retention of rainwater 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.

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.

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 improving the waterproof performance.

In a further embodiment of the present invention, referring to FIGS. 5 and 19 , in the direction from bottom to top, the lower side of the second groove 334 is inclined toward the compressor chamber 12. Thus, it is possible to further avoid the retention of rainwater in the second groove 334, and reduce the penetration of rainwater into the circuit structure such as the electric control component 32, thereby further improving the waterproof performance.

In a further embodiment of the utility model, as shown in FIG. 16 , the fins 332 include a plurality of fins 332 spaced apart along the width direction of the heat sink 331 (refer to the k direction shown in FIG. 17 ), and each fin 332 extends in the up-down direction, whereby the plurality of fins 332 can increase the contact area with the air, 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 plurality of fins 332 are spaced apart, thereby forming a plurality of drainage channels, and when rainwater falls on the heat sink 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 sink 331.

It can be understood that the fins 332 in the second group of fins 3322 are high, so that the heat exchange area of the second group of fins 3322 is large, which is beneficial to improving the heat dissipation efficiency of the radiator 33. Among them, since the first group of fins 3321 is arranged close to the fan 111 relative to the second group of fins 3322 in the width direction of the heat sink 331, and the fins 332 in the first group of fins 3321 are low, the installation interference between the first group of fins 3321 and the fan 111 can be avoided, thereby ensuring the normal rotation of the fan 111 during the operation of the air-conditioning outdoor unit 10.

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.

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.
