[0048] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0049] Reference below Figure 1-Figure 5 The outdoor unit 100 and the air conditioning apparatus according to the embodiment of the present invention are described.

[0050] refer to Figure 1-Figure 5 According to the outdoor unit 100 of the first embodiment of the present invention, the outdoor unit 100 includes: an outdoor casing 1 and an outdoor heat exchanger 2, an outdoor fan, a compressor assembly 3 and an electronic control box component 4 arranged in the outdoor casing 1. A middle partition 11 is provided in the outdoor casing 1. The middle partition 11 divides the space in the outdoor casing 1 into a fan cavity 12 and a compressor cavity 13 arranged in the left and right directions. The outdoor heat exchanger 2 and the outdoor fan are arranged in the fan cavity 12, the compressor assembly 3 is arranged in the compressor cavity 13, and at least part of the electronic control box component 4 is located in the compressor cavity 13.

[0051] Among them, at least part of the electronic control box component 4 is located in the compressor cavity 13, which may include the following situations: for example, part of the electronic control box component 4 is located in the compressor cavity 13, and another part of the electronic control box is located in the fan cavity 12; for another example, the entire electronic control box component 4 is located in the compressor cavity 13.

[0052] The outdoor casing 1 is provided with an air inlet 14 and an air outlet 15 connected to the fan cavity 12. During the operation of the outdoor fan, the outdoor fan can drive the air flow from the air inlet 14 into the outdoor casing 1 and exchange heat with the outdoor heat exchanger 2. After the heat exchange, the air is discharged to the outside of the outdoor casing 1 through the air outlet 15.

[0053] The compressor assembly 3 includes a compressor, and the compressor assembly 3 can compress and drive the refrigerant in the refrigerant circulation circuit of the outdoor unit 100.

[0054] The electronic control box assembly 4 includes an electronic control module 42 and a heat dissipation module. The heat dissipation module is used to dissipate heat from the electronic control module 42. The heat dissipation module includes a heat sink 8 and heat sinks 10 disposed on the heat sink 8. The heat sink 8 is thermally connected to the electronic control module 42. A heat dissipation channel 83 is formed within the heat sink 8. The heat dissipation channel 83 is used to allow a liquid heat exchange medium to flow through the heat dissipation channel 83 to dissipate heat from the electronic control module 42. For example, the electronic control module 42 is electrically connected to the outdoor fan, compressor assembly 3, and other components and can be used to control the operation of the outdoor fan, compressor assembly 3, and other components. During the operation of the electronic control module 42, a large amount of heat is generated. The heat sink 8 is used to dissipate heat from the electronic control module 42 to prevent damage to the electronic control module 42 due to heat generation or to prevent the normal operation of the outdoor unit 100 from being affected.

[0055] The heat exchange medium in the heat dissipation channel 83 can exchange heat with the heat dissipation plate 8 as it flows through the heat dissipation plate 8, thereby removing heat from the heat dissipation plate 8 and dissipating heat from the heat dissipation plate 8. The heat dissipation fins 10 provided on the heat dissipation plate 8 can also dissipate heat from the heat dissipation plate 8. For example, heat is transferred between the heat dissipation plate 8 and the heat dissipation fins 10, and when air flows through the heat dissipation fins 10, the heat from the heat dissipation fins 10 is removed, thereby dissipating heat from the heat dissipation plate 8. By forming the heat dissipation channel 83 in the heat dissipation plate 8 and also providing the heat dissipation fins 10 thereon, the liquid heat exchange medium in the heat dissipation channel 83 and the heat dissipation fins 10 can simultaneously dissipate heat from the heat dissipation plate 8, thereby dissipating heat from the heat dissipation plate 8 more quickly. This allows the heat dissipation plate 8 to dissipate heat from the electronic control module 42 more quickly, thereby improving the heat dissipation efficiency and effect of the electronic control module 42.

[0056] Optionally, the liquid heat exchange medium flowing through the heat dissipation channel 83 is a refrigerant to achieve refrigerant heat dissipation for the heat dissipation plate 8 .

[0057] Optionally, the liquid heat exchange medium in the heat dissipation channel 83 may be in direct contact with the heat dissipation channel 83 ; optionally, the liquid heat exchange medium in the heat dissipation channel 83 may also be in indirect contact with the heat dissipation channel 83 .

[0058] Optionally, the electric control box component 4 further includes a mounting bracket 91 , the heat sink 8 is mounted on the mounting bracket 91 , and the mounting bracket 91 is mounted on the electric control module 42 .

[0059] For example, when the outdoor unit 100 is used in a variable frequency air-conditioning device, the heat exchange medium in the heat dissipation channel 83 and the heat sink 10 simultaneously dissipate heat from the heat dissipation plate 8, thereby achieving heat dissipation of the electronic control module 42, which is beneficial to improving the heat dissipation effect of the electronic control module 42, and can effectively avoid the outdoor unit 100 from self-frequency limiting protection due to the heat generation of the electronic control box component 4 under high temperature conditions, so that the air-conditioning equipment can achieve a good air conditioning effect.

[0060] According to the outdoor unit 100 of the embodiment of the present invention, a heat dissipation channel 83 is formed in the heat dissipation plate 8 and a heat dissipation fin 10 is provided on the heat dissipation plate 8. In this way, the heat exchange medium in the heat dissipation channel 83 and the heat dissipation fin 10 can simultaneously dissipate heat from the heat dissipation plate 8, and the heat on the heat dissipation plate 8 can be more quickly discharged. The heat dissipation plate 8 can also more quickly discharge the heat on the electronic control module 42 to improve the heat dissipation efficiency and heat dissipation effect of the electronic control module 42, thereby reducing or avoiding the adverse effects of the electronic control module 42 being in a high temperature working condition on the working capacity of the outdoor unit 100, and reducing or avoiding its adverse effects on the air conditioning capacity of the air-conditioning equipment.

[0061] refer to Figure 1-Figure 3 According to some embodiments of the present invention, the electronic control box assembly 4 further includes a box body 41, an electronic control module 42 and a heat dissipation module disposed within the box body 41, the electronic control module 42 including a circuit board 421 and components 422 disposed on the circuit board 421, a heat dissipation duct 6 defined between the circuit board 421 and the box body 41, and the heat dissipation module disposed within the heat dissipation duct 6. By locating the heat dissipation module within the heat dissipation duct 6, airflow within the heat dissipation duct 6 can remove heat from the heat dissipation module while flowing through the heat dissipation module, thereby achieving air cooling and heat dissipation of the heat dissipation module, thereby facilitating improved heat dissipation of the electronic control module 42 by the heat dissipation module.

[0062] refer to Figure 1-Figure 3 According to some optional embodiments of the present invention, 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 parallel to the horizontal plane. For example, the angle between the circuit board 421 and the horizontal plane is 8°, 5°, 3°, etc. By setting the angle between the circuit board 421 and the horizontal plane to less than 10°, the electronic control module 42 is convenient to set up and easy to assemble, which helps improve the assembly and production efficiency of the outdoor unit 100.

[0063] refer to Figure 1-Figure 3 According to some optional embodiments of the present invention, a heat dissipation duct 6 is defined between the underside of the circuit board 421 and the box body 41, and the heat sink 10 is located below the heat dissipation plate 8. By defining the heat dissipation duct 6 between the underside of the circuit board 421 and the box body 41 and positioning the heat sink 10 below the heat dissipation plate 8, air in the heat dissipation duct 6 can easily flow through the heat sink 10, removing more heat from the heat sink 10 and improving the heat dissipation effect of the heat sink 10, thereby facilitating improved heat dissipation of the electronic control module 42 by the heat dissipation module.

[0064] refer to Figure 3-Figure 5 According to some optional embodiments of the present invention, a plurality of heat sinks 10 are arranged at intervals along the front-to-back direction, each heat sink 10 extending in the left-to-right direction, and a heat dissipation gap for airflow is defined between adjacent heat sinks 10. Arranging a plurality of heat sinks 10 at intervals along the front-to-back direction helps improve the heat exchange efficiency between the heat sinks 10 and the airflow within the heat dissipation duct 6. Defining a heat dissipation gap between adjacent heat sinks 10 allows the airflow within the heat dissipation duct 6 to fully exchange heat with the plurality of heat sinks 10 by flowing through the heat dissipation gap, further improving the heat exchange efficiency with the airflow and the heat dissipation effect on the heat sinks 10, thereby further improving the heat dissipation efficiency and heat dissipation effect of the heat dissipation module on the electronic control module 42.

[0065] refer to Figure 3-Figure 5 According to some optional embodiments of the present invention, the electric control box component 4 further includes a heat dissipation bracket 92. The heat dissipation bracket 92 is located within the box body 41 and below the heat dissipation plate 8 to support the heat dissipation plate 8. By providing the heat dissipation bracket 92, the heat dissipation bracket 92 provides support for the heat dissipation plate 8 in the vertical direction, so that the heat dissipation plate 8 can be stably installed within the box body 41, thereby facilitating improved installation stability and reliability of the heat dissipation module. The heat dissipation bracket 92 is provided with a heat dissipation hole 921 for avoiding the heat dissipation fin 10. By providing the heat dissipation hole 921 on the heat dissipation bracket 92 for avoiding the heat dissipation fin 10, interference between the heat dissipation fin 10 and the heat dissipation bracket 92 can be avoided, and the heat dissipation fin 10 can fully utilize the space inside the heat dissipation bracket 92, thereby facilitating optimization of the spatial layout of the electric control box component 4 and the space utilization rate within the box body 41, thereby facilitating miniaturization of the electric control box component 4 and the outdoor unit 100.

[0066] Optionally, the heat dissipation bracket 92 is supported between the heat dissipation plate 8 and the bottom wall of the box body 41 .

[0067] refer to Figure 1-Figure 3According to some optional embodiments of the present invention, the box body 41 further has an airflow inlet 411 and an airflow outlet 412 that are in communication with the heat dissipation duct 6. The airflow inlet 411 is in communication with the external space of the outdoor unit 100, and the airflow outlet 412 is in communication with the fan chamber 12. During operation of the outdoor unit 100, the operation of the outdoor fan causes an air pressure difference between the fan chamber 12 and the external space of the outdoor unit 100. As a result, the airflow in the external space can enter the heat dissipation duct 6 through the airflow inlet 411 of the box body 41 under the action of the air pressure difference, and then flow through the electronic control module 42 and the heat dissipation module, especially the heat sink 10, in the box body 41, and fully exchange heat with them to achieve heat dissipation of the electronic control module 42. Then, the airflow can flow out of the box body 41 through the airflow outlet 412 and enter the fan chamber 12.

[0068] During the operation of the outdoor unit 100, the temperature of the air flow inside the outdoor casing 1 is relatively high. If the air flow passing through the interior of the outdoor casing 1 dissipates heat to the electronic control module 42 of the electronic control box component 4 in the heat dissipation duct 6, the heat dissipation effect is relatively poor. In this way, an air flow inlet 411 connected to the external space of the outdoor unit 100 and an air flow outlet 412 connected to the fan chamber 12 are provided, so that the air flow in the external space enters the heat dissipation duct 6 to dissipate heat to the electronic control module 42. The temperature of the air flow in the external space is relatively low, which is conducive to improving the heat dissipation effect of the electronic control module 42, reducing or avoiding the electronic control box component 4 being in a high-temperature working condition, reducing or avoiding the adverse effects of the electronic control box component 4 being in a high-temperature working condition on the operation of the outdoor unit 100, and thereby reducing or avoiding adverse effects on the air conditioning capacity of the air-conditioning equipment.

[0069] For example, when the outdoor unit 100 is used in a variable frequency air-conditioning device, the heat dissipation effect is improved by dissipating the heat from the electronic control module 42 through the airflow in the external space of the outdoor housing 1, which 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 conditions, so that the air-conditioning equipment can achieve a good air conditioning effect.

[0070] refer to Figure 1-Figure 3 According to some optional embodiments of the present invention, the outdoor housing 1 is formed with an air inlet 16, which is located on the side wall of the compressor chamber 13. The air inlet 16 connects the air inlet 411 with the external space of the outdoor unit 100. By forming the air inlet 16 connecting the air inlet 411 and the external space on the outdoor housing 1, the air from the external space can smoothly enter the heat dissipation duct 6 in the box body 41 through the air inlet 411 via the air inlet 16. By locating the air inlet 16 on the side wall of the compressor chamber 13, the air inlet 16 is farther away from the fan chamber 12, thereby reducing the influence of the air flow out of the fan chamber 12 on the temperature of the air flow at the air inlet 16, and facilitating the air flow entering the box body 41 through the air inlet 16 to effectively dissipate heat from the electronic control module 42.

[0071] refer to Figure 1-Figure 3 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 communicates with the air inlet 16 and the air flow inlet 411. By defining the air intake space 5 between the electronic control box component 4 and the side wall of the compressor, which communicates with the air inlet 16 and the air flow inlet 411, air can smoothly enter the box body 41 through the air flow inlet 411 to dissipate heat from the electronic control module 42.

[0072] During the operation of the outdoor unit 100, the operation of the outdoor fan causes an air pressure difference between the fan cavity 12 and the external space of the outdoor unit 100, so that the airflow in the external space first enters the outdoor casing 1 through the air inlet 16 under the action of the air pressure difference, and then flows toward the air flow inlet 411 through the air inlet space 5 and can enter the box body 41 through the air flow inlet 411 of the box body 41, and flow through the electric control module 42 in the box body 41 to fully exchange heat with the electric control module 42 to achieve heat dissipation of the electric control module 42, and then the airflow can flow out of the box body 41 through the air flow outlet 412 and enter the fan cavity 12.

[0073] refer to Figure 1-Figure 3 According to some optional embodiments of the present invention, the air inlet 16 is located on the side of the compressor cavity 13 away from the fan cavity 12 in the left-right direction. By locating the air inlet 16 on the side of the compressor cavity 13 away from the fan cavity 12 in the left-right direction, the air inlet 16 is farther away from the fan cavity 12, thereby further reducing the impact of the airflow out of the fan cavity 12 on the temperature of the airflow at the air inlet 16, and facilitating the airflow entering the box body 41 through the air inlet 16 to effectively dissipate heat from the electronic control module 42.

[0074] According 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 is opposite to the air inlet 16 in the left-right direction; for example, the entire airflow inlet 411 is opposite to the air inlet 16 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; for example, 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 making at least a portion of the airflow outlet 412 opposite to the airflow inlet 411 in the left-right direction, when airflow from the external space flows through the air inlet 16 toward the airflow outlet 412, the airflow is less obstructed, allowing more air to flow through the electronic control module 42, reducing wind loss, thereby ensuring wind speed and achieving an effective air cooling effect.

[0075] refer to Figure 1-Figure 3According to some optional embodiments of the present invention, the air inlet 16 includes a plurality of sub-inlets arranged in parallel in the vertical direction. By forming the air inlet 16 as including a plurality of sub-inlets arranged in parallel in the vertical direction, the structural strength of the sidewall of the compressor chamber 13 is improved.

[0076] refer to Figure 1-Figure 2 According to some optional embodiments of the present invention, a waterproof cover 17 is provided on the outer surface of the side wall. The provision of the waterproof cover 17 can prevent rainwater and the like from entering the electric control box component 4 through the air inlet 16, thereby preventing safety accidents such as electric leakage. There are multiple waterproof covers 17 and they cover the outside of the sub-air inlet. The number of waterproof covers 17 is the same as the number of sub-air inlets and corresponds one to one. By having multiple waterproof covers 17 and corresponding to the number of sub-air inlets, it is beneficial to improve the protective performance of the waterproof covers 17. The waterproof cover 17 protrudes from the side wall and defines an air guide cavity between the side wall. The air guide cavity connects the air inlet 16 with the external space. By defining the air guide cavity connecting the air inlet 16 with the external space between the side walls, the obstruction of the air flow at the air inlet 16 by the waterproof cover 17 can be reduced.

[0077] refer to Figure 1-Figure 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 from top to bottom in a direction away from the air inlet 16.
