For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0042] The electric control box 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0043] like Figure 1 and Figure 2 As shown, the electric control box 100 according to the embodiment of the utility model includes a box body 1, a heat sink 2 and a vortex generator 3.

[0044] like Figure 3 As shown, the electric control box 100 is used for the air conditioner outdoor unit 1000, and the electric control box 100 is responsible for controlling and managing the operation of the outdoor unit. Various electronic components and circuits are integrated inside the electric control box 100, and these components and circuits work together to ensure that the outdoor unit can work according to the predetermined program and parameters.

[0045] By receiving signals from the indoor unit or instructions from the remote controller, the electric control box 100 can control the start and stop of the outdoor unit to meet the cooling or heating needs of the user. The electric control box 100 can automatically adjust the operating state of the outdoor unit, such as the operating frequency of the compressor, the speed of the fan, etc., according to the difference between the indoor temperature and the set temperature, to achieve more accurate temperature control.

[0046] In addition, the electric control box 100 also has a variety of protection functions, such as overload protection, overheat protection, undervoltage protection, etc. These functions can cut off the power supply or adjust the operating status in time when an abnormality occurs in the outdoor unit to avoid damage to the outdoor unit or cause safety accidents.

[0047] Specifically, Figure 1 As shown, the box body 1 includes a shell 11, an electric control board 12 and a cover plate 13. The shell 11 and the cover plate 13 together define an installation space 111. The electric control board 12 is arranged in the installation space 111, and various electronic components and circuits are arranged on the electric control board 12. The shell 11 and the cover plate 13 can protect the electric control board 12, prevent the electric control board 12 from being damaged by external impact, and prevent damage to the electronic components and circuits.

[0048] like Figure 1 and Figure 2 As shown, the box body 1 has a heat dissipation duct 112, and the heat dissipation duct 112 has a vertical direction (such as Figure 1 Both ends of the heat exchanger 112 are open, and in the air-conditioning outdoor unit 1000, the heat of the compressor and other components below the electric control box 100 is exchanged with the surrounding air, the molecular movement speed of the air is accelerated, the air density is small, and the air flow with higher temperature is affected by buoyancy. The air flow with higher temperature obtains upward lift and can enter the heat dissipation duct 112 through the opening 1121 below the heat dissipation duct 112 and continue to rise.

[0049] like Figure 1 and Figure 4 As shown, the heat sink 2 is disposed in the heat dissipation duct 112. The heat sink 2 includes a substrate 21 and a plurality of first heat sinks 22. The first heat sinks 22 are located on the substrate 21 along a first direction (eg Figure 1 The first heat sink 22 extends in the up-down direction, and the relatively high temperature airflow entering the heat dissipation duct 112 from the bottom of the electric control box 100 and the heat in the electric control box 100 exchange heat with the first heat sink 22, which can take away the relatively high temperature airflow entering the heat dissipation duct 112 from the bottom of the electric control box 100 and the heat in the electric control box 100, thereby realizing the heat dissipation of the electric control board 12 in the electric control box 100 and other components of the air conditioner outdoor unit 1000 below the electric control box 100.

[0050] like Figure 1 As shown, a plurality of first heat sinks 22 are arranged along a second direction (eg Figure 1 The first heat sinks 22 are arranged at intervals, and multiple first heat sinks 22 exchange heat with the high-temperature airflow entering the heat dissipation duct 112 from the bottom of the electric control box 100 and the heat in the electric control box 100. The radiator 2 has a good heat dissipation effect on the electric control board 12 in the electric control box 100 and other components of the air-conditioning outdoor unit 1000 below the electric control box 100.

[0051] By effectively dissipating heat, the radiator 2 can ensure the stable operation of the electric control board 12. When the electric control board 12 is overheated, it may cause the air conditioner outdoor unit 1000 to crash or freeze. The radiator 2 can better improve the stability of the system.

[0052] like Figure 1 , Figure 7 and Figure 8 As shown, the vortex generator 3 includes a fixed structure 31 and a plurality of vortex generating sheets 32, wherein the fixed structure 31 is located on the side of the first heat sink 22 away from the substrate 21 and is connected to at least part of the first heat sink 22, thereby realizing the connection between the vortex generator 3 and the heat sink 2. The vortex generating sheets 32 are located on the side of the fixed structure 31 facing the first heat sink 22 and are connected to the fixed structure 31, and a vortex generating sheet 32 ​​is provided between at least part of two adjacent first heat sinks 22, and the vortex generating sheets 32 are spaced apart from the first heat sink 22, wherein the up-down direction, the first direction, and the second direction are perpendicular to each other.

[0053] It can be understood that when the air flow flows through the vortex generator 3, the vortex generating sheet 32 ​​is affected by the flow of the air flow and the vibration of the air conditioner outdoor unit 1000 and swings, and vortices are generated around the vortex generating sheet 32, which can enhance the heat exchange effect between the air flow and the first heat sink 22 and increase the heat dissipation effect of the radiator 2.

[0054] According to the electric control box 100 of the embodiment of the utility model, by arranging the radiator 2 in the heat dissipation duct 112 which is open at both ends in the up and down directions of the box body 1, the first heat dissipation fins 22 of the radiator 2 extend in the up and down directions, and the plurality of first heat dissipation fins 22 are arranged at intervals along the second direction. The plurality of first heat dissipation fins 22 all exchange heat with the relatively high temperature airflow entering the heat dissipation duct 112 from the bottom of the electric control box 100 and the heat in the electric control box 100, and a vortex generating sheet 32 ​​is provided between the first heat dissipation fins 22 of at least some adjacent two radiators 2, and the vortex generating sheet 32 ​​is arranged at intervals from the first heat dissipation fin 22. When the airflow flows through the vortex generator 3, the vortex generating sheet 32 ​​is affected by the flow of the airflow and the vibration of the air conditioner outdoor unit 1000 to swing, and a vortex is generated around the vortex generating sheet 32, which can enhance the heat exchange effect between the airflow and the first heat dissipation fin 22 and increase the heat dissipation effect of the radiator 2.

[0055] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the vortex generators 3 are arranged in a plurality of intervals in the vertical direction. The vortex generating sheets 32 of the plurality of vortex generators 3 are all affected by the flow of the airflow and the vibration of the air conditioner outdoor unit 1000 to swing, and vortices are generated around the vortex generating sheets 32, which can repeatedly strengthen the heat exchange effect of the airflow and the first heat sink 22, thereby increasing the heat dissipation effect of the radiator 2.

[0056] In some embodiments of the present invention, Figure 4-Figure 6 As shown, a plurality of second heat sinks 23 are provided at the upper end of each first heat sink 22, the second heat sink 23 is connected to the base plate 21, the plurality of second heat sinks 23 are arranged at intervals in the vertical direction, and the second heat sink 23 at the bottom is arranged at intervals from the first heat sink 22, wherein, in the vertical direction, the size of the second heat sink 23 is smaller than that of the first heat sink 22. It can be understood that the second heat sink 23 with a smaller size in the vertical direction further aggravates the turbulence of the airflow, and the rising airflow with a higher temperature briefly forms a turbulent flow at the second heat sink 23, further strengthening the heat exchange effect between the airflow and the first heat sink 22, and increasing the heat dissipation effect of the radiator 2.

[0057] In some embodiments of the utility model, the vortex generating sheet 32 ​​is a flexible member. Under the condition of not increasing the flow resistance too much, the mechanical vibration of the air conditioner outdoor unit 1000 and the flow of the air flow can be used to obtain the swinging power to generate the vortex to further strengthen the heat exchange effect of the air flow and the first heat sink 22, thereby increasing the heat dissipation effect of the radiator 2.

[0058] In some embodiments of the utility model, the size of the vortex generating sheet 32 ​​along the second direction is 5-20μm. It is understandable that the size of the vortex generating sheet 32 ​​along the second direction can be 5μm, 6μm, 7μm, 8μm, 9μm, 10μm, 11μm, 12μm, 13μm, 14μm, 15μm, 16μm, 17μm, 18μm, 19μm or 20μm. The size of the vortex generating sheet 32 ​​along the second direction is not less than 5μm, which can avoid the size of the vortex generating sheet 32 ​​being too small and the vortex generating sheet 32 ​​sagging under the action of gravity; the size of the vortex generating sheet 32 ​​along the second direction is not more than 20μm, so that the vortex generating sheet 32 ​​can rely on the mechanical vibration of the air conditioner outdoor unit 1000 and the flow of airflow to obtain the power of swinging to generate vortex, further strengthen the heat exchange effect of the airflow and the first heat sink 22, and increase the heat dissipation effect of the radiator 2.

[0059] In some embodiments of the utility model, the ratio of the size of the vortex generating sheet 32 ​​along the first direction to the size of the vortex generating sheet 32 ​​along the up-down direction is 2.5-5. It is understandable that the ratio of the size of the vortex generating sheet 32 ​​along the first direction to the size of the vortex generating sheet 32 ​​along the up-down direction can be 2.5, 3, 3.5, 4, 4.5 or 5. The ratio of the size of the vortex generating sheet 32 ​​along the first direction to the size of the vortex generating sheet 32 ​​along the up-down direction is not less than 2.5, which can make the size of the vortex generating sheet 32 ​​along the first direction and the size of the vortex generating sheet 32 ​​along the up-down direction more reasonable, and increase the effect of generating vortices around the vortex generating sheet 32; the ratio of the size of the vortex generating sheet 32 ​​along the first direction to the size of the vortex generating sheet 32 ​​along the up-down direction is not greater than 5, which can avoid the imbalance of the size of the vortex generating sheet 32 ​​along the first direction and the size of the vortex generating sheet 32 ​​along the up-down direction, and can avoid the vortex generating sheet 32 ​​from sagging under the action of gravity.

[0060] In some embodiments of the present invention, Figure 1 and Fig. 9 As shown, an opening 1121 penetrating the box body 1 is provided on one of the two side walls of the heat dissipation duct 112 that are opposite to each other along the second direction, and the opening 1121 is located at the upper end of the box body 1. The electric control box 100 further includes a heat dissipation vent structure 4, which is provided outside the box body 1 and located at the opening 1121. The heat dissipation vent structure 4 has an outlet duct and a first air inlet 41 and an air outlet 42 that are connected to the outlet duct, and the first air inlet 41 is opposite to and connected to the opening 1121. The airflow in the heat dissipation duct 112 can enter the outlet duct from the first air inlet 41 and flow out from the air outlet 42, so that the hotter airflow located at the upper end of the box body 1 can flow out from the air outlet 42, effectively transporting the waste heat in the electric control box 100 to the environment, and achieving the effect of efficient heat dissipation.

[0061] Furthermore, if Figure 1 and Fig. 9 As shown, a plurality of shutters 43 are arranged in the vertical direction in the opening 1121. This can prevent water from entering the electric control box 100 when the wind wheel 201 of the air conditioner outdoor unit 1000 throws water, and can prevent mosquitoes from entering the electric control box 100, thereby reducing the safety hazard of the electric control box 100.

[0062] Furthermore, the air outlet 42 is arranged at one side of the heat dissipation air outlet structure 4 along the first direction, and the heat dissipation air outlet structure 4 also includes a second air inlet connected to the air outlet duct, and the second air inlet is arranged at one side of the heat dissipation air outlet structure 4 away from the air outlet 42 along the first direction. When the air conditioner outdoor unit 1000 is working, the wind wheel 201 rotates to allow the air flow to flow from the second air inlet to the air outlet 42 through the air outlet duct, forming a "narrow mouth effect" in the air outlet duct, and the air flow velocity in the air outlet duct is relatively large, forming a negative pressure and sucking the air flow in the heat dissipation duct 112 out from the first air inlet 41, which can increase the air flow velocity and flow field disturbance at the opening 1121, and improve the heat dissipation effect of the radiator 2.

[0063] Furthermore, if Figure 1 and Fig. 9 As shown, a drain port 44 connected to the air outlet duct is provided on the bottom wall of the heat dissipation vent structure 4. When the airflow entering the air outlet duct contacts the wall surface of the heat dissipation vent structure 4, condensation may be generated. The condensation may flow out of the heat dissipation vent structure 4 from the drain port 44 on the bottom wall under the action of gravity, thereby preventing the accumulated water in the heat dissipation vent structure 4 from flowing back into the electric control box 100, thereby reducing the safety hazard of the electric control box 100.

[0064] Furthermore, if Figure 1 and Figure 2 As shown, the air-conditioning outdoor unit 1000 has a fan cavity 200 and a compressor cavity 300 arranged at intervals along the second direction, the box body 1 is arranged in the compressor cavity 300, the opening 1121 is located on the side of the box body 1 facing the fan cavity 200, the heat dissipation air outlet structure 4 is located in the fan cavity 200, and the air outlet 42 is connected to the fan cavity 200. When the air-conditioning outdoor unit 1000 is working, the compressor generates heat and the wind wheel 201 rotates. The heat of the compressor in the compressor chamber 300 is exchanged with the surrounding air. The molecular movement speed of the air is accelerated, the air density is small, and the air flow with higher temperature is affected by buoyancy. The air flow with higher temperature gains upward lift and can enter the heat dissipation duct 112 from the opening 1121 below the heat dissipation duct 112. The heat is dissipated and continues to rise under the heat dissipation turbulence effect of the radiator 2 and the vortex generator 3. The wind wheel 201 in the fan chamber 200 rotates, driving the air flow from the second air inlet through the air outlet duct to the air outlet 42, forming a "narrow mouth effect" in the air outlet duct. The air flow velocity in the air outlet duct is large, forming a negative pressure and sucking the air flow in the heat dissipation duct 112 out from the first air inlet 41, which can increase the air flow velocity and flow field disturbance at the opening 1121, and improve the heat dissipation effect of the radiator 2.

[0065] An electric control box 100 according to a specific embodiment of the present invention is described below with reference to the accompanying drawings. It is worth noting that the following description is merely exemplary and is intended to be used to explain the present invention, but cannot be construed as limiting the present invention.

[0066] like Figure 1 As shown, the electric control box 100 includes a box body 1, a heat sink 2, a vortex generator 3 and a heat dissipation vent structure 4.

[0067] Specifically, the box body 1 has a heat dissipation duct 112, and both ends of the heat dissipation duct 112 in the upper and lower directions are open;

[0068] The radiator 2 is arranged in the heat dissipation duct 112. The radiator 2 includes a substrate 21 and a plurality of first heat dissipation fins 22. The first heat dissipation fins 22 are located on one side of the substrate 21 along the first direction and are connected to the substrate 21. The first heat dissipation fins 22 extend in the up-down direction. The plurality of first heat dissipation fins 22 are arranged at intervals along the second direction. The plurality of first heat dissipation fins 22 exchange heat with the airflow with a relatively high temperature entering the heat dissipation duct 112 from the bottom of the electric control box 100 and the heat in the electric control box 100. The radiator 2 has a good heat dissipation effect on the electric control board 12 in the electric control box 100 and other components of the air conditioner outdoor unit 1000 below the electric control box 100. A plurality of second heat dissipation fins 23 are arranged at the upper end of each first heat dissipation fin 22. The second heat dissipation fins 23 are connected to the substrate 21. The plurality of second heat dissipation fins 23 are arranged at intervals along the up-down direction and the lowermost second heat dissipation fins 23 are arranged at intervals from the first heat dissipation fins 22. In the up-down direction, the size of the second heat dissipation fins 23 is smaller than that of the first heat dissipation fins 22. The second heat sink 23 further intensifies the turbulence of the airflow. The rising airflow with a higher temperature briefly forms a turbulent flow at the second heat sink 23 , further strengthening the heat exchange effect between the airflow and the first heat sink 22 , thereby increasing the heat dissipation effect of the radiator 2 .

[0069] The vortex generators 3 are arranged in a plurality of intervals along the vertical direction. The vortex generators 3 include a fixed structure 31 and a plurality of vortex generating sheets 32. The fixed structure 31 is located on the side of the first heat sink 22 away from the substrate 21 and is connected to at least part of the first heat sink 22. The vortex generating sheets 32 are located on the side of the fixed structure 31 facing the first heat sink 22 and are connected to the fixed structure 31. A vortex generating sheet 32 ​​is provided between at least two adjacent first heat sinks 22. The vortex generating sheets 32 are spaced apart from the first heat sink 22. The vortex generating sheets 32 of the plurality of vortex generators 3 are all affected by the flow of the airflow and the vibration of the air conditioner outdoor unit 1000 to swing. Vortexes are generated around the vortex generating sheets 32, which can strengthen the heat exchange effect between the airflow and the first heat sink 22 for multiple times, thereby increasing the heat dissipation effect of the radiator 2. The vortex generating sheet 32 ​​is a flexible part that can generate vortices by relying on the mechanical vibration of the air conditioner outdoor unit 1000 and the flow of airflow to obtain the swinging power without increasing the flow resistance too much, thereby further enhancing the heat exchange effect of the airflow and the first heat sink 22 and increasing the heat dissipation effect of the radiator 2.

[0070] An opening 1121 penetrating the box body 1 is provided on one of the two side walls of the heat dissipation duct 112 that are opposite to each other along the second direction. The opening 1121 is located at the upper end of the box body 1. The electric control box 100 further includes a heat dissipation vent structure 4, which is provided outside the box body 1 and located at the opening 1121. The heat dissipation vent structure 4 includes an air outlet duct and a first air inlet 41 and an air outlet 42 that are connected to the air outlet duct. The first air inlet 41 is opposite to and connected to the opening 1121. The air outlet 42 is provided on one side of the heat dissipation vent structure 4 along the first direction. The heat dissipation vent structure 4 further includes a second air inlet that is connected to the air outlet duct. The second air inlet is provided on one side of the heat dissipation vent structure 4 that is away from the air outlet 42 along the first direction. The air conditioner outdoor unit 1000 has a fan cavity 200 and a compressor cavity 300 arranged at intervals along the second direction. The box body 1 is arranged in the compressor cavity 300, the opening 1121 is located on the side of the box body 1 facing the fan cavity 200, the heat dissipation air outlet structure 4 is located in the fan cavity 200, and the air outlet 42 is connected to the fan cavity 200.

[0071] When the air-conditioning outdoor unit 1000 is working, the compressor generates heat and the wind wheel 201 rotates. The heat of the compressor in the compressor chamber 300 is exchanged with the surrounding air. The molecular movement speed of the air is accelerated, the air density is small, and the air flow with higher temperature is affected by buoyancy. The air flow with higher temperature gains upward lift and can enter the heat dissipation duct 112 from the opening 1121 below the heat dissipation duct 112. The heat is dissipated and continues to rise under the heat dissipation turbulence effect of the radiator 2 and the vortex generator 3. The wind wheel 201 in the fan chamber 200 rotates, driving the air flow from the second air inlet through the air outlet duct to the air outlet 42, forming a "narrow mouth effect" in the air outlet duct. The air flow velocity in the air outlet duct is large, forming a negative pressure and sucking the air flow in the heat dissipation duct 112 out from the first air inlet 41, which can increase the air flow velocity and flow field disturbance at the opening 1121, and improve the heat dissipation effect of the radiator 2.

[0072] A plurality of shutters 43 are arranged in the opening 1121 at intervals in the vertical direction. This can prevent water from entering the electric control box 100 when the wind wheel 201 of the air conditioner outdoor unit 1000 throws water, and can prevent mosquitoes from entering the electric control box 100, thereby reducing the potential safety hazard of the electric control box 100. A drain port 44 connected to the air outlet duct is provided on the bottom wall of the heat dissipation vent structure 4. When the airflow entering the air outlet duct contacts the wall surface of the heat dissipation vent structure 4, condensation may be generated. The condensation may flow out of the heat dissipation vent structure 4 from the drain port 44 on the bottom wall under the action of gravity, thereby preventing the accumulated water in the heat dissipation vent structure 4 from flowing back into the electric control box 100, thereby reducing the potential safety hazard of the electric control box 100.

[0073] The air-conditioning outdoor unit 1000 according to the embodiment of the present invention includes the above-mentioned electric control box 100 .

[0074] According to the air-conditioning outdoor unit 1000 of the embodiment of the utility model, by arranging the radiator 2 in the heat dissipation duct 112 which is open at both ends in the up-down direction of the box body 1, the first heat dissipation fins 22 of the radiator 2 extend in the up-down direction, and the plurality of first heat dissipation fins 22 are arranged at intervals in the second direction. The plurality of first heat dissipation fins 22 all exchange heat with the relatively high temperature airflow entering the heat dissipation duct 112 from the bottom of the electric control box 100 and the heat in the electric control box 100, and a vortex generating sheet 32 ​​is provided between the first heat dissipation fins 22 of at least some adjacent two radiators 2, and the vortex generating sheet 32 ​​is arranged at intervals from the first heat dissipation fin 22. When the airflow flows through the vortex generator 3, the vortex generating sheet 32 ​​is affected by the flow of the airflow and the vibration of the air-conditioning outdoor unit 1000 to swing, and a vortex is generated around the vortex generating sheet 32, which can enhance the heat exchange effect between the airflow and the first heat dissipation fin 22 and increase the heat dissipation effect of the radiator 2.
