Optionally, a heat dissipation bracket 92 is supported between the heat dissipation plate 8 and the bottom wall of the case 41.

Referring to fig. 1 to 3, according to some alternative embodiments of the present utility model, the case 41 further has an air inlet 411 and an air outlet 412 communicating with the heat dissipation duct 6, the air inlet 411 communicating with the external space of the outdoor unit 100, and the air outlet 412 communicating with the fan chamber 12. During the operation of the outdoor unit 100, the operation of the outdoor fan causes an air pressure difference between the inside of the fan chamber 12 and the outside space of the outdoor unit 100, so that the air flow in the outside space can enter the heat dissipation air duct 6 through the air flow inlet 411 of the box 41 under the action of the air pressure difference, flow through the electric control module 42 and the heat dissipation module in the box 41, especially the heat dissipation fin 10, and exchange heat with the electric control module 42 sufficiently to dissipate heat of the electric control module 42, and then flow out of the box 41 through the air flow outlet 412 and enter the fan chamber 12.

In the working process of the outdoor unit 100, if the air flow inside the outdoor unit casing 1 is higher in temperature, the electric control module 42 of the electric control box component 4 is cooled in the cooling air duct 6 by the air flow inside the outdoor unit casing 1, so that the cooling effect is poor, and the air flow in the external space enters the cooling air duct 6 to cool the electric control module 42 by arranging the air flow inlet 411 communicated with the external space of the outdoor unit 100 and the air flow outlet 412 communicated with the fan cavity 12, so that the temperature of the air flow in the external space is lower, thereby being beneficial to improving the cooling effect of the electric control module 42, reducing or avoiding the adverse effect of the electric control box component 4 on the working of the outdoor unit 100 due to the high temperature working condition, and further reducing or avoiding the adverse effect on the air conditioning capacity of the air conditioning equipment.

During the operation of the outdoor unit 100, the operation of the outdoor fan causes an air pressure difference between the inside of the fan chamber 12 and the outside space of the outdoor unit 100, so that the air flow in the outside space enters the outdoor unit casing 1 through the air inlet 16 under the action of the air pressure difference, flows through the air inlet space 5 toward the air flow inlet 411 and can enter the box 41 through the air flow inlet 411 of the box 41, and flows through the electronic control module 42 and the electronic control module 42 in the box 41 to perform sufficient heat exchange to achieve heat dissipation of the electronic control module 42, and then the air flow can flow out of the box 41 through the air flow outlet 412 and enter the fan chamber 12.

Referring to fig. 1-3, in accordance with some alternative embodiments of the present utility model, the air intake 16 is located on a side of the compressor cavity 13 that is remote from the fan cavity 12 in a side-to-side direction. By locating the air inlet 16 on the side of the compressor chamber 13 far from the fan chamber 12 in the left-right direction, the sample air inlet 16 is far from the fan chamber 12, so that the influence of the air flow flowing out of the fan chamber 12 on the temperature of the air flow at the air inlet 16 is further reduced, and the air flow entering the box 41 through the air inlet 16 is beneficial to effectively radiating the electric control module 42.

At least a portion of the air flow outlet 412 is opposite to the air flow inlet 411 in the left-right direction, for example, the air flow outlet 412 is opposite to the air flow inlet 411 in the left-right direction as a whole. By making at least the upper portion of the air inlet 411 opposite to the air inlet 16 in the left-right direction, and making at least part of the air outlet 412 opposite to the air inlet 411 in the left-right direction, when the air in the external space flows toward the air outlet 412 through the air inlet 16, the air flow is less obstructed, more air can flow through the electronic control module 42, and the air loss is reduced, so that the air speed is ensured, and the effective air cooling effect is further realized.

Referring to fig. 1-3, according to some alternative embodiments of the present utility model, the air intake 16 includes a plurality of sub-air intake openings arranged side-by-side in an up-down direction. By forming the intake port 16 to include a plurality of sub-intake ports arranged side by side in the up-down direction, it is advantageous to improve the structural strength of the side wall of the compressor chamber 13.

Referring to fig. 1-2, according to some alternative embodiments of the present utility model, a waterproof cover 17 is provided on the outer surface of the side wall, and by providing the waterproof cover 17, rainwater or the like can be prevented from entering the electronic control box member 4 through the air inlet 16, so that safety accidents such as electric leakage and the like can be avoided. The number of the waterproof covers 17 is the same as and corresponds to the number of the sub air inlets one by one, and the waterproof covers 17 are a plurality of and correspond to the number of the sub air inlets, so that the protection performance of the waterproof covers 17 is improved. The waterproof cover 17 protrudes out of the side wall and defines an air guide cavity with the side wall, the air guide cavity is communicated with the air inlet 16 and the external space, and the waterproof cover 17 defines the air guide cavity communicated with the air inlet 16 and the external space with the side wall, so that the interference of the waterproof cover 17 on the air flow at the air inlet 16 can be reduced.

Referring to fig. 1-2, according to some alternative embodiments of the present utility model, the outer surface of the waterproof cover 17 is formed with a flow guiding surface 171, and the flow guiding surface 171 extends obliquely in a direction away from the air inlet 16 in a top-to-bottom direction. By forming the outer surface of the waterproof cover 17 with the flow guiding surface 171 and extending the flow guiding surface 171 obliquely in the direction away from the air inlet 16 in the top-down direction, the shell of the flow guiding surface 171 thus exerts a guiding action on rainwater or the like so as to flow in the direction away from the air inlet 16, which is advantageous in optimizing the waterproof effect of the waterproof cover 17.

Referring to fig. 1-2, according to some alternative embodiments of the utility model, a portion of the box 41 is located within the fan chamber 12, and a portion of the box 41 located within the fan chamber 12 is formed with an airflow outlet 412. By forming the airflow outlet 412 on the portion of the box 41 located in the fan cavity 12, an effective air pressure difference can be formed between the airflow outlet 412 and the airflow inlet 411 during the operation of the outdoor fan, so that the airflow in the external space can smoothly enter the box 41 via the airflow inlet 411 to dissipate heat of the electronic control module 42.

Alternatively, the box 41 is entirely located within the compressor chamber 13, with the left side wall of the box 41 flush with the septum 11, and the airflow outlet 412 is located on the left side wall of the box 41.
