[0052] Embodiments of the present invention 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 the present invention, and should not be construed as limiting the present invention.

[0053] The following is for reference. Figures 1-5 An outdoor unit 100 and an air conditioning device according to an embodiment of the present invention are described.

[0054] refer to Figures 1-2 According to an embodiment of the first aspect of the present invention, the outdoor unit 100 includes: an outdoor unit housing 1 and an outdoor heat exchanger 2, an outdoor fan, a compressor assembly 3, an electrical control box component 4, and a heat dissipation pipe disposed within the outdoor unit housing 1. The outdoor unit housing 1 is provided with a partition 11, which divides the space within the outdoor unit housing 1 into a fan cavity 12 and a compressor cavity 13 arranged in a left-right direction. The outdoor heat exchanger 2 and the outdoor fan are disposed within the fan cavity 12, the compressor assembly 3 is disposed within the compressor cavity 13, and at least a portion of the electrical control box component 4 is located within the compressor cavity 13.

[0055] The fact that at least a portion of the electrical control box component 4 is located within the compressor cavity 13 can include the following situations: for example, part of the electrical control box component 4 is located within the compressor cavity 13, and another part of the electrical control box is located within the fan cavity 12; or, for another example, the entire electrical control box component 4 is located within the compressor cavity 13.

[0056] An air inlet 14 and an air outlet 15 connected to a ventilation fan chamber 12 are formed on the outdoor unit casing 1. During the operation of the outdoor fan, the outdoor fan can drive the airflow to enter the outdoor unit casing 1 through the air inlet 14 and exchange heat with the outdoor heat exchanger 2. After heat exchange, the airflow is discharged to the outside of the outdoor unit casing 1 through the air outlet 15.

[0057] The compressor assembly 3 includes a compressor, which can play the role of compressing and driving the refrigerant in the refrigerant circulation loop of the outdoor unit 100.

[0058] The electrical control box component 4 includes a box body 41 and an electrical control module 42 disposed within the box body 41. The box body 41 has an airflow inlet 411 and an airflow outlet 412. The airflow inlet 411 is connected to the compressor chamber 13, and the airflow outlet 412 is connected to the fan chamber 12. The electrical control module 42 can be electrically connected to the outdoor fan, compressor assembly 3, etc., disposed within the outdoor unit housing 1, and can be used to control the operation of the outdoor fan, compressor assembly 3, etc. During the operation of the outdoor unit 100, the operation of the outdoor fan drives airflow into the box body 41 through the airflow inlet 411, and the airflow flows through the electrical control module 42 for air cooling.

[0059] The heat pipe 7 has a heat dissipation channel for the flow of the heat exchange medium, and the heat pipe 7 is thermally connected to the electronic control module 42. The heat exchange medium carries away the heat from the electronic control module 42 by flowing within the heat dissipation channel, thereby achieving heat dissipation for the electronic control module 42.

[0060] According to an embodiment of the present invention, the outdoor unit 100 has an airflow inlet 411 and an airflow outlet 412 in the housing 41 of the electrical control box component 4, and a heat dissipation pipe 7 is provided. During the operation of the outdoor unit 100, the operation of the outdoor fan drives the airflow to enter the housing 41 through the airflow inlet 411. The airflow flows through the electrical control module 42 to cool it. The heat exchange medium carries away the heat on the electrical control module 42 by flowing in the heat dissipation channel of the heat dissipation pipe 7. In this way, the airflow entering the housing 41 through the airflow inlet 411 and the heat exchange medium in the heat dissipation pipe 7 simultaneously dissipate heat on the electrical control module 42, which is beneficial to improving the heat dissipation efficiency and effect of the electrical control module 42, reducing or avoiding the adverse effects on the operation of the outdoor unit 100 caused by the electrical control box component 4 being in a high-temperature condition, and thus reducing or avoiding the adverse effects on the air conditioning capacity of the air conditioning equipment.

[0061] refer to Figures 1-2 According to some embodiments of the present invention, the outdoor unit housing 1 has an air inlet 16, which is located on the side wall of the compressor cavity 13 and connects the air inlet 411 with the external space of the outdoor unit 100. During the operation of the outdoor unit 100, the operation of the outdoor fan creates a pressure difference between the fan cavity 12 and the external space of the outdoor unit 100. Under the action of this pressure difference, the airflow from the external space can enter the housing through the air inlet and the air inlet 411, then flow through the electronic control module 42 in the housing 41 and exchange heat with the electronic control module 42 to dissipate heat from the electronic control module 42. Then, the airflow can flow out of the housing 41 through the air outlet 412 and enter the fan cavity 12.

[0062] During the operation of the outdoor unit 100, the airflow temperature inside the outdoor unit casing 1 is relatively high. If the airflow inside the outdoor unit casing 1 is used to dissipate heat from the electrical control module 42 of the electrical control box component 4, the heat dissipation effect is poor. Therefore, using the airflow from the external space of the outdoor unit casing 1 to dissipate heat from the electrical control module 42 is beneficial to improve the heat dissipation effect, further reducing or avoiding the electrical control box component 4 being in a high-temperature operating condition. This can reduce or avoid the impact of high temperature on the normal operation of the electrical control box component 4, thereby avoiding affecting the normal operation of the outdoor unit 100.

[0063] For example, when the outdoor unit 100 is used in a variable frequency air conditioning device, the heat dissipation effect is improved by using the airflow in the external space of the outdoor unit casing 1 to dissipate heat from the electronic control module 42. This can effectively prevent the outdoor unit 100 from automatically limiting its frequency due to the heat generated by the electronic control box component 4 under high temperature conditions, so that the air conditioning device can achieve a good air conditioning effect.

[0064] By forming an air inlet 16 on the outdoor unit casing 1 that connects the airflow inlet 411 to the external space, the airflow from the external space can smoothly enter the housing 41 through the airflow inlet 411 via the airflow inlet 16. In addition, by connecting the airflow inlet 411 to the external space of the outdoor unit 100, during the operation of the outdoor unit 100, the operation of the outdoor fan will create an air pressure difference between the fan chamber 12 and the external space of the outdoor unit 100. This allows the airflow from the external space to enter the housing 41 through the airflow inlet 411 to dissipate heat from the electronic control module 42, and then flow out of the housing 41 back to the fan chamber 12 through the airflow outlet 412. The airflow temperature in the external space of the outdoor unit 100 is lower than the airflow temperature inside the outdoor unit 100. This airflow from the external space of the outdoor unit 100 is beneficial for improving the heat dissipation effect by dissipating heat from the electronic control module 42.

[0065] refer to Figures 1-2 According to some optional embodiments of the present invention, an air intake space 5 is defined between the electronic control box component 4 and the side wall of the compressor, and the air intake space 5 connects the air intake port 16 and the airflow inlet 411. By defining the air intake space 5 connecting the air intake port 16 and the airflow inlet 411 between the electronic control box component 4 and the side wall of the compressor, airflow can smoothly enter the box 41 through the airflow inlet 411 to dissipate heat from the electronic control module 42.

[0066] During the operation of the outdoor unit 100, the operation of the outdoor fan creates a pressure difference between the fan cavity 12 and the external space of the outdoor unit 100. Under the action of this pressure difference, the airflow from the external space first enters the outdoor unit casing 1 through the air inlet 16, then flows through the air intake space 5 toward the airflow inlet 411, and can enter the casing 41 through the airflow inlet 411. It then flows through the electronic control module 42 inside the casing 41 and exchanges heat with the electronic control module 42 to achieve heat dissipation for the electronic control module 42. Then the airflow can flow out of the casing 41 through the airflow outlet 412 and enter the fan cavity 12.

[0067] refer to Figures 1-2 According to some optional embodiments of the present invention, in the left-right direction, the air inlet 16 is located on the side of the compressor cavity 13 away from the fan cavity 12. By positioning the air inlet 16 on the side of the compressor cavity 13 away from the fan cavity 12 in the left-right direction, the distance between the air inlet 16 and the fan cavity 12 is relatively large, which helps to reduce the influence of the airflow flowing out of the fan cavity 12 on the temperature of the airflow at the air inlet 16, and facilitates the effective heat dissipation of the airflow entering the housing 41 through the air inlet 16 for the electronic control module 42.

[0068] refer to Figures 1-2According to some optional embodiments of the present invention, at least a portion of the airflow inlet 411 is opposite to the air inlet 16 in the left-right direction. For example, a portion of the airflow inlet 411 and the air inlet 16 are opposite to each other in the left-right direction; or the entire airflow inlet 411 and the air inlet 16 are opposite to each other in the left-right direction. At least a portion of the airflow outlet 412 is opposite to the airflow inlet 411 in the left-right direction. For example, a portion of the airflow outlet 412 is opposite to the airflow inlet 411 in the left-right direction; or the entire airflow outlet 412 is opposite to the airflow inlet 411 in the left-right direction. By making at least a portion of the airflow inlet 411 opposite to the air inlet 16 in the left-right direction and at least a portion of the airflow outlet 412 opposite to the airflow inlet 411 in the left-right direction, the airflow in the external space flows through the air inlet 16 toward the airflow outlet 412 with less obstruction, allowing more airflow to pass through the electronic control module 42, reducing wind loss, thereby ensuring wind speed and achieving an effective air cooling effect.

[0069] refer to Figures 1-2 According to some optional embodiments of the present invention, the air inlet 16 includes a plurality of sub-air inlets arranged side by side in the vertical direction. By forming the air inlet 16 to include a plurality of sub-air inlets arranged side by side in the vertical direction, it is beneficial to improve the structural strength of the sidewall of the compressor cavity 13.

[0070] refer to Figures 1-2 According to some optional embodiments of the present invention, a waterproof cover 17 is provided on the outer surface of the sidewall. By providing the waterproof cover 17, rainwater and other substances can be prevented from entering the electrical control box component 4 through the air inlet 16, thereby avoiding safety accidents such as leakage. Multiple waterproof covers 17 are provided and cover the outside of the sub-air inlets. The number of waterproof covers 17 is the same as the number of sub-air inlets and corresponds one-to-one. By providing multiple waterproof covers 17 corresponding to the number of sub-air inlets, the protective performance of the waterproof covers 17 is improved. The waterproof cover 17 protrudes from the sidewall and defines an air guide cavity between itself and the sidewall. The air guide cavity connects the air inlet 16 to the external space. By defining an air guide cavity between the sidewall and the air inlet 16, the obstruction of the airflow at the air inlet 16 by the waterproof cover 17 is reduced.

[0071] refer to Figures 1-2 According to some optional embodiments of the present invention, a guide surface 171 is formed on the outer surface of the waterproof cover 17, and the guide surface 171 extends obliquely in a direction away from the air inlet 16 in a top-to-bottom direction. By forming a guide surface 171 on the outer surface of the waterproof cover 17 and making the guide surface 171 extend obliquely in a direction away from the air inlet 16 in a top-to-bottom direction, the guide surface 171 guides rainwater and the like to flow in a direction away from the air inlet 16, which helps to optimize the waterproof effect of the waterproof cover 17.

[0072] refer toFigures 1-2 According to some embodiments of the present invention, a portion of the housing 41 is located within the fan cavity 12, and the portion of the housing 41 located within the fan cavity 12 forms an airflow outlet 412. By forming an airflow outlet 412 in the portion of the housing 41 located within 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, allowing airflow from the external space to smoothly enter the housing 41 through the airflow inlet 411 to dissipate heat from the electronic control module 42.

[0073] Optionally, the entire housing 41 is located inside the compressor cavity 13, the left side wall of the housing 41 is flush with the middle partition 11, and the air outlet 412 is located on the left side wall of the housing 41.

[0074] refer to Figures 1-3 According to some optional embodiments of the present invention, the projection of the air outlet 15 onto the reference plane is a first projection, and the projection of the housing 41 onto the reference plane is a second projection. The reference plane is a vertical plane perpendicular to the front-back direction, and the first projection and the second projection are spaced apart. By separating the first projection and the second projection, the portion of the housing 41 located within the fan cavity 12 can be prevented from obstructing the air outlet 15 and affecting the air outlet 15's airflow effect.

[0075] refer to Figures 1-3 According to some embodiments of the present invention, the electronic control module 42 includes a circuit board 421 and components 422 disposed on the circuit board 421, wherein the angle between the circuit board 421 and the horizontal plane is less than 10°. For example, the circuit board 421 is placed horizontally and is parallel to the horizontal plane. For example, the angle between the circuit board 421 and the horizontal plane is 8°, 5°, 3°, etc. By making the angle between the circuit board 421 and the horizontal plane less than 10°, the electronic control module 42 is convenient to set up and easy to assemble, which helps to improve the assembly production efficiency of the outdoor unit 100.

[0076] refer to Figures 1-2 According to some optional embodiments of the present invention, a heat dissipation duct 6 is defined between the lower side of the circuit board 421 and the housing 41. The heat dissipation duct 6 connects the airflow inlet 411 and the airflow outlet 412. At least some components 422 are located within the heat dissipation duct 6. For example, some components 422 are located within the heat dissipation duct 6; for example, all components 422 are located within the heat dissipation duct 6. By defining the heat dissipation duct 6 between the lower side of the circuit board 421 and the housing 41 and placing at least some components 422 within the heat dissipation duct 6, the airflow entering the housing 41 via the airflow inlet 411 can flow through at least some components 422 and effectively exchange heat with them to dissipate heat.

[0077] refer to Figures 1-4According to some optional embodiments of the present invention, the electrical control box component 4 is installed at the upper end of the partition plate 11. By installing the electrical control box component 4 at the upper end of the partition plate 11, interference between the electrical control box component 4 and other components in the fan cavity 12 or compressor cavity 13 can be avoided, and the space layout inside the outdoor unit 100 is reasonable.

The electronic control module 42 is installed in the first housing 41. The second housing 41 is located below the first housing 41 and supported by the middle partition 11. The lower side of the circuit board 421 and the second housing 41 define a heat dissipation channel. At least a portion of the electronic control module 42 is located in the heat dissipation channel.

[0081] refer to Figures 1-4 According to some embodiments of the present invention, the outdoor unit 100 further includes a heat dissipation pipe 7, which has a heat dissipation channel for the flow of heat exchange medium, and is thermally connected to the electronic control module 42. Optionally, the heat exchange medium flowing in the heat dissipation pipe 7 may be a refrigerant. By providing the heat dissipation pipe 7 and making the heat dissipation pipe 7 thermally connected to the electronic control module 42, the heat dissipation pipe 7 can further improve the heat dissipation effect on the electronic control module 42.

By using the heat dissipation pipe 7 to dissipate heat from the first region 423, which has a larger heat generation, it is beneficial to achieve effective heat dissipation from the first region 423 of the electronic control module 42, thereby effectively avoiding local overheating of the electronic control module 42.

[0084] refer to Figures 1-2According to some optional embodiments of the present invention, the first region 423 and the second region 424 are arranged side by side in the front-back direction. By arranging the first region 423 and the second region 424 side by side in the front-back direction, the partitioning layout of the first region 423 and the second region 424 is reasonable, which also facilitates the installation of the heat dissipation pipe 7.

[0085] refer to Figures 1-2 According to some optional embodiments of the present invention, at least a portion of the airflow inlet 411 is opposite to the second region 424 in the left-right direction.

By making at least a portion of the airflow inlet 411 opposite to the second region 424 and at least a portion of the airflow outlet 412 opposite to the second region 424, the airflow from the external space can effectively dissipate heat from the second region 424, thereby allowing the heat generated by the first region 423 and the second region 424 of the electronic control module 42 to be carried away in a timely manner so that the electronic control module 42 can operate normally.

The outdoor unit housing 1 also includes a top panel, which is located above the front panel, side panels, and rear panel and covers the receiving space. A central partition 11 is also provided inside the outdoor unit housing 1, which divides the receiving space inside the outdoor unit housing 1 into a fan chamber 12 and a compressor chamber 13 arranged in a left-right direction.

[0103] The outdoor heat exchanger 2 and the outdoor fan are located inside the fan chamber 12. The outdoor unit casing 1 has an air inlet 14 and an air outlet 15 connected to the fan chamber 12.
