[0051] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, in which 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 drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0052] Below, with reference toFigures 1-4 Describe an outdoor unit 100 and an air conditioning device according to an embodiment of the present utility model.

[0053] Reference Figures 1-4 , according to an outdoor unit 100 of the first aspect embodiment of the present utility model, the outdoor unit 100 includes: an outdoor unit housing 1 and an outdoor heat exchanger 2, an outdoor fan, a compressor assembly, and an electric control box component 4 provided inside the outdoor unit housing 1. A middle partition 11 is provided inside the outdoor unit housing 1, and the middle partition 11 divides the space inside the outdoor unit housing 1 into a fan chamber 12 and a compressor chamber 13 arranged in the left-right direction. The outdoor heat exchanger 2 and the outdoor fan are provided in the fan chamber 12, the compressor assembly is provided in the compressor chamber 13, and at least part of the electric control box component 4 is located in the compressor chamber 13.

[0054] Among them, at least part of the electric control box component 4 being located in the compressor chamber 13 may include the following situations: for example, part of the electric control box component 4 is located in the compressor chamber 13, and the other part of the electric control box is located in the fan chamber 12; for another example, the electric control box component 4 is entirely located in the compressor chamber 13.

[0055] An air inlet 14 and an air outlet 15 communicating with the fan chamber 12 are formed on the outdoor unit housing 1. During the operation of the outdoor fan, the outdoor fan can drive air flow to enter the outdoor unit housing 1 from the air inlet 14, exchange heat with the outdoor heat exchanger 2, and then be discharged to the outside of the outdoor unit housing 1 through the air outlet 15 after heat exchange.

[0056] The compressor assembly includes a compressor, and the compressor assembly can play a role in compressing and driving the refrigerant in the refrigerant circulation circuit of the outdoor unit 100.

[0057] The electric control box component 4 includes a box body 41 and an electric control module 42 provided inside the box body 41. The box body 41 has an air inlet 411 and an air outlet 412. The air inlet 411 communicates with the external space of the outdoor unit 100, and the air outlet 412 communicates with the fan chamber 12. The electric control module 42 can be electrically connected to the outdoor fan, the compressor assembly, etc. provided inside the outdoor unit housing 1, and can be used to control the operation of components such as the outdoor fan and the compressor assembly. During the operation of the outdoor unit 100, the operation of the outdoor fan causes a pressure difference between the fan chamber 12 and the external space of the outdoor unit 100, so that the air flow in the external space can enter through the air inlet 411 of the box body 41 under the action of this pressure difference, flow through the electric control module 42 inside the box body 41, exchange heat fully with the electric control module 42 to realize heat dissipation of the electric control module 42, and then the air flow can flow out of the box body 41 through the air outlet 412 and enter the fan chamber 12.

[0058] During the operation of the outdoor unit 100, the temperature of the air flow inside the outdoor unit housing 1 is relatively high. If the electronic control module 42 of the electronic control box component 4 is cooled by the air flow inside the outdoor unit housing 1, the heat dissipation effect is poor. Therefore, cooling the electronic control module 42 by the air flow in the external space of the outdoor unit housing 1 is beneficial to improving the heat dissipation effect, reducing or avoiding the electronic control box component 4 being in a high-temperature working condition, thereby reducing or avoiding the normal operation of the electronic control box component 4 being affected by high temperature and further avoiding affecting the normal operation of the outdoor unit 100.

[0059] For example, when the outdoor unit 100 is applied to a variable-frequency air-conditioning device, cooling the electronic control module 42 by the air flow in the external space of the outdoor unit housing 1 to improve the heat dissipation effect can effectively prevent the outdoor unit 100 from self-limiting frequency protection due to the heat generated by the electronic control box component 4 under high-temperature working conditions, so that the air-conditioning device can achieve a good air-conditioning effect.

[0060] Among them, the air flow inlet 411 is located on the front side of the box body 41, and the air flow outlet 412 is located on the side of the box body 41 close to the fan chamber 12 in the left-right direction. The air flow in the external space of the outdoor unit 100 enters the box body 41 through the air flow inlet 411 on the front side of the box body 41. Under the action of the air pressure difference between the air flow inlet 411 and the air flow outlet 412, it flows towards the air flow outlet 412 located on the side of the box body 41 close to the fan chamber 12 in the left-right direction. The flow path of these air flows in the box body 41 is generally to enter the box body 41 along the front-back direction first and then change direction along the left-right direction towards the air flow outlet 412, so that the flow velocity of the air flow is reduced to avoid generating a large air flow noise. In addition, under such a flow path, it is possible to reduce or avoid the air flow being blocked by some components on the electronic control module 42 and resulting in the generation of eddy currents, thereby being able to avoid the air flow noise generated thereby, and avoiding the inability to effectively take away some heat due to the generation of eddy currents, and avoiding a relatively high local temperature inside the box body 41 caused thereby.

[0061] According to the outdoor unit 100 of the embodiment of the utility model, by making the air flow inlet 411 located on the front side of the box body 41 and making the air flow outlet 412 located on the side of the box body 41 close to the fan chamber 12 in the left and right direction, the change in the position of the air flow inlet 411 and the air flow outlet 412 will cause the flow speed and flow direction of the air flow to change. Such an arrangement makes it possible for the air flow path in the box body 41 to no longer be perpendicular to a certain direction under the guidance of the air flow inlet 411 and the air flow outlet 412, which is conducive to reducing the flow speed of the air flow to avoid generating large air flow noise; in addition, it can also prevent the air flow from being blocked by certain components on the electric control module 42 perpendicular to this direction due to flowing in a certain direction and generating eddy currents, thereby avoiding the air flow noise generated thereby and avoiding the inability to effectively carry away part of the heat due to the generation of eddy currents, which is conducive to reducing the air flow noise generated in the electric control box component 4 and improving the heat dissipation effect of the electric control module 42.

[0062] refer to Figures 1-4 According to some embodiments of the utility model, the electric control module 42 includes a circuit board 421 and components 422 arranged on the circuit board 421, a heat dissipation duct 6 is defined between the circuit board 421 and the box body 41, at least part of the components 422 are located in the heat dissipation duct 6, and the airflow inlet 411 and the airflow outlet 412 are connected to the heat dissipation duct 6. Among them, at least part of the components 422 are located in the heat dissipation duct 6, which may include the following situations: for example, part of the components 422 are located in the heat dissipation duct 6; for another example, all the components 422 are located in the heat dissipation duct 6. By defining the heat dissipation duct 6 between the circuit board 421 and the box body 41 and at least part of the components 422 are located in the heat dissipation duct 6, after the airflow entering the box body 41 through the airflow inlet 411 enters the box body 41, it can fully flow through the circuit board 421 and at least part of the components 422 through the heat dissipation duct 6 and effectively exchange heat with them to achieve heat dissipation.

[0063] refer to Figure 2 According to some optional embodiments of the utility model, the component 422 with the largest height among the components 422 located in the heat dissipation duct 6 is the first component 4221, and the airflow inlet 411 and the first component 4221 are staggered. By staggering the airflow inlet 411 and the first component 4221, it is possible to avoid the first component 4221 blocking the flow of airflow, so that the airflow can flow smoothly in the heat dissipation duct 6 to take away more heat from the electric control module 42, which is conducive to further improving the heat dissipation effect of the electric control module 42.

[0064] refer to Figures 1-2, according to some alternative embodiments of the present utility model, the included 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, there is an included angle between the circuit board 421 and the horizontal plane, and the included angle between the circuit board 421 and the horizontal plane is 8°, 5°, 3°, etc. By making the included angle between the circuit board 421 and the horizontal plane less than 10°, the electronic control module 42 is convenient to set and easy to assemble, which is beneficial to improving the assembly production efficiency of the outdoor unit 100.

[0065] Reference Figures 2-4 , according to some alternative embodiments of the present utility model, the box body 41 includes a first box body 413 and a second box body 414 located inside the first box body 413. The structure of the box body 41 is compact, and the first box body 413 provides functions such as support and protection for the second box body 414. The upper side of the second box body 414 is open, and the circuit board 421 is supported on the top of the second box body 414. The second box body 414 provides a supporting effect on the circuit board 421 to improve the installation stability and reliability of the electronic control module 42. By making the upper side of the second box body 414 open to avoid structures such as components 422 provided on the circuit board 421, these structures can make full use of the internal space of the second box body 414, which is beneficial to optimizing the spatial layout of the electronic control box component 4. The circuit board 421 and the second box body 414 jointly define a heat dissipation air duct 6 located below the circuit board 421. An air flow inlet 411 is formed on the front side wall of the second box body 414. Such a setting enables the air flow in the external space to accurately flow from the front side of the box body 41 to the heat dissipation air duct 6.

[0066] Optionally, the box body 41 further includes a box cover body 416, and the box cover body 416 is supported on the top of the second box body 414 and is used to cover the electronic control module 42.

[0067] Reference Figures 2-4 , according to some alternative embodiments of the present utility model, a wind guiding structure 415 is provided at the air flow inlet 411, and the wind guiding structure 415 is used to guide the air flow to enter the box body 41 through the air flow inlet 411. The wind guiding structure 415 includes a wind guiding frame 4151 and a wind guiding plate 4152. The wind guiding frame 4151 and the wind guiding plate 4152 can guide the air flow to flow along a specific direction, ensuring that the air flow can smoothly enter the heat dissipation air duct 6 instead of entering the box body 41 in a scattered manner. It is also beneficial to guide more air flow into the heat dissipation air duct 6, all of which are beneficial to improving the heat dissipation efficiency. The wind guiding frame 4151 surrounds the outer peripheral side of the air flow inlet 411 and is located on the front surface of the second box body 414. The wind guiding plate 4152 is arranged inside the wind guiding frame 4151 and extends in the left-right direction. The setting of the wind guiding frame 4151 is beneficial to enhancing the structural strength of the second box body 414 and can form a shielding effect on the air flow inlet 411 to reduce or avoid rainwater, etc. from entering the box body 41.

[0068] ReferenceFigures 2-4 , according to some alternative embodiments of the present utility model, a plurality of air guide plates 4152 are arranged at intervals in the up-down direction. By arranging a plurality of air guide plates 4152 at intervals in the up-down direction, the plurality of air guide plates 4152 can better guide the air flow, and the air flow entering the heat dissipation air duct 6 can be refined into multiple strands, which is beneficial to increasing the contact area between the air flow and the electronic control module 42 for sufficient heat exchange between the air flow and the electronic control module 42, helping to improve the heat dissipation efficiency; at the same time, the structure of the plurality of air guide plates 4152 is also beneficial to enhancing the structural strength of the second box body 414.

[0069] Reference Figures 2-4 , according to some alternative embodiments of the present utility model, the air guide plate 4152 extends obliquely downward in the direction from the rear to the front. By making the air guide plate 4152 extend obliquely downward in the direction from the rear to the front, the inclined air guide plate 4152 helps to reduce the resistance when the air flow passes through the air inlet 411.

[0070] Reference Figure 2 And Figure 4 , according to some alternative embodiments of the present utility model, a first air outlet 4121 is formed on the first box body 413, and a second air outlet 4122 is formed on the second box body 414. The first air outlet 4121 and the second air outlet 4122 are opposite and communicated in the left-right direction, and the air outlet 412 includes the first air outlet 4121 and the second air outlet 4122. Among them, the first air outlet 4121 includes a plurality of first sub-air outlets arranged at intervals, the second air outlet 4122 includes a plurality of second sub-air outlets arranged at intervals, and the extending directions of the first sub-air outlets and the second sub-air outlets intersect. By making the extending directions of the first sub-air outlets and the second sub-air outlets intersect, it can effectively prevent rainwater and the like from entering the box body 41 through the air outlet 412, thereby avoiding safety accidents such as electric leakage caused by rainwater and the like. At the same time, the first air outlet 4121 and the second air outlet 4122 are opposite and communicated in the left-right direction, which can effectively make the air flow pass smoothly.

[0071] Reference Figures 2-4 , according to some alternative embodiments of the present utility model, the size of the part of the second box body 414 located in the compressor cavity 13 in the left-right direction is L1, the size of the air inlet 411 in the left-right direction is L2, and the ratio range of L2 to L1 is 0.5 to 1. Optionally, the ratio range of L2 to L1 can be 0.5, 0.6, 0.7, 0.75, 0.8, 0.9, 0.95, or 1, etc. By making the ratio range of L2 to L1 be 0.5 to 1, the size of the air inlet 411 in the left-right direction is larger, so that more air flow can enter the box body 41 through the air inlet 411, which is beneficial to increasing the air flow rate for dissipating heat from the electronic control module 42 to better meet the heat dissipation requirements.

[0072] refer to Figures 2-4 According to some optional embodiments of the present invention, the size of the portion of the second box body 414 located in the compressor cavity 13 in the left-right direction is L1, and in the left-right direction, the side wall of the second box body 414 away from the fan cavity 12 is the first side wall 4141, and the distance between the airflow inlet 411 and the first side wall 4141 in the left-right direction is L3, and the ratio of L3 to L1 ranges from 0 to 0.15. Optionally, the ratio of L3 to L1 can range from 0, 0.02, 0.05, 0.08, 0.10, 0.12, 0.14, 0.15, etc. By making the ratio range of L3 to L1 be 0 to 0.15, the distance between the edge position of the airflow inlet 411 and the first side wall 4141 in the left-right direction is small, so that the airflow can enter the box body 41 from a position closer to the first side wall 4141, thereby improving the coverage rate of the airflow entering the box body 41 through the airflow inlet 411 on the electric control module 42 in the left-right direction, so that the airflow can effectively flow through the electric control module 42 in the left-right direction and fully exchange heat with it, thereby avoiding local overheating of the electric control module 42 near the first side wall 4141, thereby helping to further improve the heat dissipation effect.

[0074] The electronic control module 42 includes a first region 423 and a second region 424 arranged in the front-rear direction. The heat generation amount of the first region 423 is greater than that of the second region 424. The heat dissipation pipe 7 is used to dissipate heat from the first region 423, and the component 422 located in the second region 424 is located in the heat dissipation air duct 6. By using the heat dissipation pipe 7 to dissipate heat from the first region 423 with a larger heat generation amount, it is beneficial to effectively dissipate heat from the first region 423 of the electronic control module 42 with a larger heat generation amount, thereby effectively avoiding the situation of local overheating of the electronic control module 42; in addition, by making the component 422 located in the second region 424 located in the heat dissipation air duct 6, the air flow in the heat dissipation air duct 6 can effectively dissipate heat from the second region 424. Such an arrangement realizes the partitioned heat dissipation of the electronic control module 42, and respectively adopts appropriate heat dissipation methods for the first region 423 and the second region 424 with different heat generation amounts, so as to effectively dissipate heat from the whole electronic control module 42, and adopting the air-cooled heat dissipation method for the second region 424 with a lower heat generation amount is also beneficial to reducing the production cost of the outdoor unit 100.

[0077] Optionally, the height of the component 422 in the second region 424 is greater than the height of the component 422 in the first region 423. By making the height of the component 422 in the second region 424 greater than the height of the component 422 in the first region 423, it avoids the higher component 422 from interfering with the setting of the heat dissipation pipe 7, and the higher component 422 can make full use of the space in the heat dissipation air duct 6 to fully exchange heat with the air flow.

The air inlet 16 is located on the front side of the compressor chamber 13, and the air inlet 16 communicates the air flow inlet 411 with the external space of the outdoor unit 100. By forming the air inlet 16 on the outdoor housing 1 that communicates the air flow inlet 411 and the external space, it is convenient for the air flow in the external space to smoothly enter the heat dissipation air duct 6 in the box body 41 through the air inlet 16 and the air flow inlet 411.

[0080] Reference Figure 1 Figure 1 According to some alternative embodiments of the present utility model, an air inlet space is defined between the electronic control box component 4 and the side wall of the compressor chamber 13. The air inlet space communicates the air inlet 16 with the air flow inlet 411. By defining the air inlet space that communicates the air inlet 16 and the air flow inlet 411 between the electronic control box component 4 and the side wall of the compressor, it is beneficial to reduce the resistance to the air flow, so that the air flow can smoothly enter the box body 41 through the air flow inlet 411 to dissipate heat from the electronic control module 42.

[0081] During the operation of the outdoor unit 100, the operation of the outdoor fan causes a pressure difference between the inside of the fan chamber 12 and the external space of the outdoor unit 100. As a result, the air flow in the external space enters the outdoor housing 1 through the air inlet 16 under the action of this pressure difference, then flows towards the air flow inlet 411 through the air inlet space and can enter the box body 41 through the air flow inlet 411 of the box body 41, and flows through the electronic control module 42 in the box body 41 to fully exchange heat with the electronic control module 42 to achieve heat dissipation of the electronic control module 42. Then, the air flow can flow out of the box body 41 through the air flow outlet 412 and enter the fan chamber 12.

For example, a part of the air flow inlet 411 is opposite to the air inlet 16 in the front-rear direction; for example, the entire air flow inlet 411 is opposite to the air inlet 16 in the front-rear direction. By making at least a part of the air flow inlet 411 opposite to the air inlet 16 in the front-rear direction, when the air flow in the external space flows through the air inlet 16 towards the direction of the air flow outlet 412, the air flow encounters less resistance, more air flow can flow through the electronic control module 42, reducing air loss, thereby ensuring the wind speed and achieving an effective air cooling effect.

[0085] The waterproof cover 17 protrudes from the outdoor housing 1 and defines a wind guiding cavity between the waterproof cover 17 and the outdoor housing 1. The wind guiding cavity communicates the air inlet 16 with the external space. By defining a wind guiding cavity communicating the air inlet 16 with the external space between the waterproof cover 17 and the side wall, the obstruction of the airflow at the air inlet 16 by the waterproof cover 17 can be reduced, so that the airflow can smoothly enter the outdoor housing 1 through the air inlet 16.
