[0037] 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.

[0038] The air conditioner outdoor unit 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0039] like Figures 1-4 As shown, the air-conditioning outdoor unit 100 according to an embodiment of the present invention includes a housing 1 , a middle partition 2 , a motor bracket 3 and an electric control component 4 .

[0040] Specifically, a central partition 2 is disposed within the housing 1 to divide the space within the housing 1 into a horizontally separated fan chamber 11 and a compression chamber 12. The impeller 6 of the air conditioner outdoor unit 100 and the motor 5 that drives the impeller 6 are disposed within the fan chamber 11, and the compressor is disposed within the compression chamber 12. The central partition 2 separates the fan chamber 11 from the compression chamber 12 to ensure the reliable operation of the impeller 6 and the compressor. A motor bracket 3 is disposed within the housing 1 and is located in the fan chamber 11. The bottom end of the motor bracket 3 can be connected to the bottom wall of the housing 1. The motor 5 that drives the impeller 6 is disposed on the motor bracket 3. The motor bracket 3 is used to support the motor 5 and ensure the reliable operation of the impeller 6.

[0041] The electric control component 4 includes an electric control bracket 41 and an electric control box 42. The electric control bracket 41 is connected to the upper end of the middle partition 2 and the upper end of the motor bracket 3. The electric control box 42 is arranged on the electric control bracket 41. Since one end of the electric control bracket 41 is connected to the motor bracket 3, the motor bracket 3 is located in the fan cavity 11, so that more of the electric control box 42 can be located in the fan cavity 11. Due to the rotation of the wind wheel 6 in the fan cavity 11, there is airflow in the fan cavity 11. Placing more of the electric control box 42 in the fan cavity 11 can increase the flow of airflow on the surface of the electric control box 42, which is beneficial to the heat dissipation of the electric control box 42. In addition, under the premise that the size of the electric control box 42 is certain, since one end of the electric control bracket 41 is connected to the motor bracket 3 located in the fan chamber 11, the end of the electric control box 42 away from the motor bracket 3 can be farther away from the side panel of the compression chamber 12 away from the motor bracket 3, which facilitates the outward lead-out of the connection terminal of the electric control box 42 away from the motor bracket 3, facilitates the connection between the lead and other components, and facilitates the assembly of the air-conditioning outdoor unit 100.

[0042] Furthermore, the end of the electrical control box 42 near the motor bracket 3 is tilted upward. The wind wheel 6 is an axial-flow wind wheel with axial-flow blades. Software simulation analysis shows that the blade profile of the axial-flow blades results in a greater tangential wind speed than an axial wind speed. The upward tilt of the end of the electrical control box 42 near the motor bracket 3 positions the electrical control box 42 as close as possible to the direction of the tangential force of the axial-flow blades, maximizing airflow and positioning the electrical control box 42. This prevents horizontal placement of the electrical control box 42, which would otherwise affect airflow, thereby enhancing heat dissipation.

[0043] According to the air conditioner outdoor unit 100 of the embodiment of the present invention, by connecting the electric control bracket 41 to the upper end of the motor bracket 3 and the upper end of the middle partition 2, and positioning the electric control box 42 on the electric control bracket 41, a larger portion of the electric control box 42 can be positioned within the fan cavity 11, thereby facilitating heat dissipation of the electric control box 42. Furthermore, by tilting the end of the electric control box 42 adjacent to the motor bracket 3 upward, the electric control box 42 can be positioned as close as possible to the direction of the tangential force of the axial fan blades, thereby maximizing airflow and preventing the electric control box 42 from being horizontally positioned, thereby enhancing heat dissipation of the electric control box 42.

[0044] Furthermore, if Figure 2 As shown, the angle between the electrical control box 42 and the horizontal direction is 0-5°. The angle between the lower or upper surface of the electrical control box 42 and the horizontal direction can be used as a reference. This allows the electrical control box 42 to be as close as possible to the direction of the tangential force of the axial fan blades, positioning the electrical control box 42 as close as possible to the position where the air flow is maximized. This prevents the electrical control box 42 from being placed horizontally, which would affect the air flow, thereby increasing the heat dissipation effect of the electrical control box 42. Furthermore, it prevents the electrical control box 42 from being tilted too much, which would affect the assembly of the top cover of the housing 1.

[0045] Optionally, the angle between the electric control box 42 and the horizontal direction may be 1°, 2°, 3° or 4°, etc.

[0046] In some embodiments of the present invention, the minimum distance between the electronic control assembly 4 and the circle formed by the maximum outer contour of the fan wheel 6 of the air conditioner outdoor unit 100 is 10-20 mm. This prevents the electronic control assembly 4 from colliding with the fan wheel 6 during rotation, and allows the electronic control assembly 4 to be as close to the fan wheel 6 as possible, thereby positioning the electronic control box 42 at a location with the maximum air flow, thereby enhancing the heat dissipation effect of the electronic control box 42.

[0047] The electric control box 42 can be located above or below the electric control bracket 41. When the electric control box 42 is located above the electric control bracket 41, the minimum distance between the electric control component 4 and the circle formed by the maximum outer contour rotation of the wind wheel 6 is the minimum distance between the electric control bracket 41 and the circle formed by the maximum outer contour rotation of the wind wheel 6. When the electric control box 42 is located below the electric control bracket 41, the minimum distance between the electric control component 4 and the circle formed by the maximum outer contour rotation of the wind wheel 6 is the minimum distance between the electric control box 42 and the circle formed by the maximum outer contour rotation of the wind wheel 6. Figure 2 In the example shown, the electric control box 42 is arranged above the electric control bracket 41, and the minimum distance between the electric control component 4 and the circle formed by the maximum outer contour rotation of the wind wheel 6 is the minimum distance between the electric control bracket 41 and the circle formed by the maximum outer contour rotation of the wind wheel 6.

[0048] In some embodiments of the present invention, Figure 2 As shown, the electronic control assembly 4 is spaced apart from the top wall of the housing 1. This prevents the electronic control assembly 4 from interfering with the assembly of the top cover. Furthermore, a gap is created between the electronic control assembly 4 and the top cover, allowing the fan chamber 11 and the compression chamber 12 to communicate above the electronic control assembly 4. This allows for airflow within the fan chamber 11 and the compression chamber 12, facilitating heat dissipation for the electronic control box 42 and the compressor. Optionally, the installation height of the electronic control assembly 4 should not exceed that of the motor bracket 3 to avoid interfering with the assembly of the top cover.

[0049] Among them, the electric control box 42 can be arranged above the electric control bracket 41, or it can be arranged below the electric control bracket 41. When the electric control box 42 is arranged above the electric control bracket 41, there is a gap between the electric control box 42 and the top cover of the shell 1. When the electric control bracket 41 is located above the electric control box 42, there is a gap between the electric control bracket 41 and the top cover of the shell 1.

[0050] like Figure 4 、 Figure 5 、 Figure 7 and Figure 8 As shown, the electric control box 42 is disposed above the electric control bracket 41, and the electric control bracket 41 is provided with heat dissipation holes 413. This allows the outer surface of the electric control box 42 to be more exposed to air, thereby improving the heat dissipation effect of the electric control box 42. In addition, the heat dissipation holes 413 on the electric control box 42 can also allow the air in the fan cavity 11 to flow to the electric control box 42 through the heat dissipation holes 413, further facilitating the heat dissipation of the electric control box 42.

[0051] Furthermore, at least some of the heat dissipation holes 413 are used to connect the fan chamber 11 and the compression chamber 12. This allows the fan chamber 11 and the compression chamber 12 to be connected below the electronic control box 42, allowing airflow in the fan chamber 11 and the compression chamber 12 to circulate, which is beneficial to heat dissipation of the electronic control box 42 and the compressor.

[0052] like Figure 4 and Figure 5 As shown, the air conditioner outdoor unit 100 also includes a heat exchanger 7, which is disposed within the housing 1 and located on the same side as the motor bracket 3 and the middle partition 2. The electric control bracket 41 is connected to the motor bracket 3 and the middle partition 2 on the side away from the heat exchanger 7. According to the thermal imaging camera, there are three stable and high heat sources within the housing 1: the motor 5, the heat exchanger 7, and the compressor. Therefore, comparative testing has shown that placing the electric control box 42 away from heat sources such as the heat exchanger 7 provides better heat dissipation. Therefore, connecting the electric control bracket 41 to the side of the motor bracket 3 and the middle partition 2 away from the heat exchanger 7 can keep the electric control box 42 away from the heat exchanger 7, which is beneficial for heat dissipation of the electric control box 42.

[0053] like Figure 6-Figure 8 As shown, the electrical control bracket 41 is provided with a wire routing notch 414. This notch 414 allows for routing the motor 5 wiring to the motor bracket 3. The motor 5 wiring passes from the fan chamber 11 through the wire routing notch 414 into the compression chamber 12 and connects to the end of the electrical control box 42 away from the motor bracket 3. Furthermore, the wire routing notch 414 is spaced apart from the electrical control box 42. This ensures a safe distance between the motor wiring and the electrical control box 42, preventing overheating that could affect the life of the motor wiring.

[0054] Furthermore, as shown in FIG Figure 3 and 4 As shown, the wire notch 414 is located on the side of the electric control bracket 41 close to the heat exchanger 7. This allows the electric control box 42 on the motor bracket 3 to be closely adjacent to the side of the housing 1 away from the heat exchanger 7, increasing the distance between the electric control box 42 and the heat exchanger 7, which is beneficial to heat dissipation of the electric control box 42.

[0055] In some embodiments of the present invention, Figure 7 As shown, the motor bracket 3 is provided with thermal insulation ribs 415, which are located between the electrical control box 42 and the heat exchanger 7. This separates the electrical control box 42 from the heat exchanger 7, preventing heat from the heat exchanger 7 from being transferred to the electrical control box 42 and facilitating heat dissipation from the electrical control box 42. Furthermore, the thermal insulation ribs 415 are coated with a thermal insulation material to block heat radiation from the heat exchanger 7.

[0056] exist Figure 7 In the example shown, the electric control box 42 is located above the electric control bracket 41 , and the heat insulation rib 415 is formed by folding upwards one end of the electric control bracket 41 close to the heat exchanger 7 .

[0057] like Figure 7 As shown, the electric control bracket 41 is an integrated part. This can improve the assembly efficiency of the electric control bracket 41. Of course, the present invention is not limited to this. Figure 4 and Figure 8As shown, the electric control bracket 41 may further include a first bracket 411 and a second bracket 412. The first bracket 411 is connected to the motor bracket 3, the second bracket 412 is connected to the middle partition 2, and the electric control box 42 is connected to the first bracket 411 and the second bracket 412. This can improve the flexibility of installing the electric control bracket 41, thereby improving the flexibility of installing the electric control box 42.

[0058] In some embodiments of the present invention, the electric control bracket 41 is connected to the motor bracket 3 and the middle partition 2, and the electric control box 42 is connected to the electric control bracket 41 by fasteners. This can simplify the reliability of the connection between the electric control bracket 41, the motor bracket 3, and the middle partition 2, as well as the reliability of the connection between the electric control box 42 and the electric control bracket 41. It can also simplify the connection method between the electric control bracket 41, the motor bracket 3, and the middle partition 2, as well as the connection method between the electric control box 42 and the electric control bracket 41, thereby improving assembly efficiency.

[0059] exist Figure 4 and Figure 8 In the example shown, the electric control bracket 41 includes a first bracket 411 and a second bracket 412. The first bracket 411 is connected to the motor bracket 3, and the second bracket 412 is connected to the middle partition 2. The first bracket 411 includes a first connecting plate 4111, a second connecting plate 4112 and a third connecting plate 4113. The first connecting plate 4111 extends in the horizontal direction. The first connecting plate 4111 is connected to the upper end of the motor bracket 3 by a fastener. One end of the second connecting plate 4112 is connected to one end of the second connecting plate 4112. One end of the third connecting plate 4113 is connected to the other end of the second connecting plate 4112. The connecting plate 4113 is located below the first connecting plate 4111. The end of the third connecting plate 4113 connected to the second connecting plate 4112 is horizontally spaced apart from the end of the first connecting plate 4111 connected to the second connecting plate 4112. The second connecting plate 4112 is inclined toward the third connecting plate 4113 from top to bottom. The third connecting plate 4113 is angled downward away from the horizontal, in other words, it is tilted downward away from the second connecting plate 4112. The end of the electrical control box 42 closest to the motor bracket 3 is connected to the third connecting plate 4113 via fasteners. Furthermore, the second connecting plate 4112 is provided with a heat dissipation hole 413, which extends from the second connecting plate 4112 to the third connecting plate 4113.

[0060] The second bracket 412 includes a main body plate 4121, and both ends of the main body plate 4121 are provided with bent edges 4122. The bent edges 4122 include a transition plate 4123 connected to the main body plate 4121 and a support plate 4124 connected to the transition plate 4123. The bent edges 4122 can be formed by bending the main body plate 4121 upward and then toward both sides. The transition plate 4123 of the bent edge 4122 on the side of the second bracket 412 close to the motor bracket 3 is connected to the middle partition plate 2 by fasteners. The two support plates 4 Both support plates 4124 are used to support the electrical control box 42. Both support plates 4124 are tilted downward in the direction from the motor bracket 3 to the middle partition 2 to support the electrical control box 42. The end of the electrical control box 42 away from the motor bracket 3 is connected to the support plate 4124 on the side of the second bracket 412 away from the motor bracket 3 via fasteners. At this time, the electrical control box 42 effectively connects the first bracket 411 and the second bracket 412 together, thereby connecting the motor bracket 3 and the middle partition 2 together, increasing the strength of the entire machine. In addition, the main plate 4121 is provided with a heat dissipation hole 413. To ensure communication between the fan chamber 11 and the compression chamber 12, the heat dissipation hole 413 can extend to the side of the bent edge 4122 near the motor bracket 3. The wire notch 414 is formed on the bent edge 4122.

[0061] exist Figure 7 In the illustrated example, the electric control bracket 41 is a single piece, namely, the first bracket 411 and the second bracket 412 are a single piece. The structure of the integrated motor bracket 3 can be substantially the same as that of the separate first bracket 411 and the second bracket 412. The difference lies in that the end of the third connecting plate 4113, which is away from the first connecting plate 4111, is connected to the support plate 4124 of the bent edge 4122 of the second bracket 412, which is closer to the motor bracket 3. This makes the electric control bracket 41 a single piece. In this case, the middle partition 2 and the motor bracket 3 are connected together through the electric control bracket 41, thereby increasing the strength of the entire machine. In addition, in this example, the heat dissipation holes 413 on the first bracket 411 are located only on the third connecting plate 4113.

[0062] The integrated electric control bracket 41 and the split electric control bracket 41 both have three supporting points for the electric control box 42 , thereby improving the reliability of fixing the electric control box 42 .

[0063] Hereinafter, an air conditioner according to an embodiment of the present invention will be described.

Furthermore, by tilting the end of the electric control box 42 adjacent to the motor bracket 3 upward, the electric control box 42 can be positioned as close as possible to the direction of the tangential force of the axial fan blades, thereby maximizing airflow and preventing the horizontal placement of the electric control box 42 from affecting airflow. This improves the heat dissipation effect of the electric control box 42.
