[0065] The utility model provides a kind of air conditioner outdoor unit 100, below referring to Figures 1-17 Air conditioner outdoor unit 100 is described, wherein Figure 1 、 Figure 2 The perspective view of air conditioner outdoor unit 100.

[0066] Referring to Figures 1-3 , air conditioner outdoor unit 100 includes shell 1, shell 1 is installed in outdoor, shell 1 forms the overall appearance of air conditioner outdoor unit 100.

[0067] Shell 1 inside defines installation cavity, installation cavity is used to install, fixed the parts of air conditioner outdoor unit 100. Wherein, shell 1 has top end and bottom end, top end and bottom end are the two ends of shell 1 in the height direction of itself.

[0068] Continuing to refer to Figure 2 , shell 1 can include air inlet 11. Air inlet 11 is communicated with installation cavity, and air inlet 11 is used as the entrance of the external air inflow of shell 1.

[0069] The casing 1 can include an air outlet 12. The air outlet 12 is in communication with the installation cavity, and the air outlet 12 serves as an outlet for the heat-exchanged air in the casing 1.

[0070] The outdoor air outside the casing 1 enters the inside of the casing 1 through the air inlet 11 and is finally discharged to the outside through the air outlet 12.

[0071] With reference to Figure 3 The air conditioner outdoor unit 100 further includes a wind guide ring 121, which is arranged at the air outlet 12 and in which part of the fan wheel of the outdoor fan is located, so that the wind guide ring 121 can guide the wind.

[0072] With reference to Figure 1 The casing 1 is connected with an air outlet shroud 5, which is located at the air outlet 12 and covers the outside of the wind guide ring 121. The air outlet shroud 5 can guide the airflow to be discharged in a specific direction. By optimizing the airflow path, the air outlet shroud 5 ensures that the heat-exchanged air discharged by the air conditioner can be quickly dispersed, reduces the energy loss when the air conditioner outdoor unit 100 operates, and improves the performance and energy efficiency of the air conditioning system.

[0073] In some embodiments of the present application, the air conditioner outdoor unit 100 can include an outdoor fan 4. The outdoor fan 4 is arranged in the installation cavity and is used to drive the outdoor air outside the casing 1 to enter the installation cavity through the air inlet 11. The outdoor fan 4 drives the air in the installation cavity to flow in the direction from the air inlet 11 to the air outlet 12.

[0074] The outdoor fan 4 can be a axial fan. When the axial fan is applied to the air conditioner outdoor unit 100, it can improve the performance of the outdoor unit and thus the entire air conditioning system due to its low aerodynamic noise and high air volume.

[0075] The air conditioner outdoor unit 100 can include an outdoor heat exchanger 6, which is arranged in the installation cavity and is used to exchange heat with the air in the casing 1. The outdoor heat exchanger 6 is closer to the air inlet 11 relative to the outdoor fan 4. With reference to Figure 2 , Figure 4 The outdoor heat exchanger 6 is installed on the inside of the air inlet 11.

[0076] The outdoor fan 4 is arranged between the outdoor heat exchanger 6 and the air outlet 12. Under the action of the outdoor fan 4, the outdoor air enters the installation cavity through the air inlet 11, exchanges heat with the outdoor heat exchanger 6 in the installation cavity, and is discharged from the air outlet 12 to the outside of the casing 1 under the driving of the outdoor fan 4.

[0077] The air conditioner outdoor unit 100 can include a compressor, which is arranged in the installation cavity in the casing 1.

[0078] The air conditioner can include a throttling device for throttling. The throttling device can be provided in the air conditioner indoor unit or the air conditioner outdoor unit 100.

[0079] The air conditioner can include an indoor unit, i.e., an air conditioner indoor unit, which includes an indoor heat exchanger.

[0080] The air conditioner can include a refrigerant circuit. The refrigerant circuit is formed by connecting the air conditioner indoor unit and the air conditioner outdoor unit 100 using a connection pipe to circulate the refrigerant. The air conditioner can perform indoor cooling or heating by circulating the refrigerant through the compressor, the condenser, the throttling device, and the evaporator in sequence through the refrigerant circuit.

[0081] The indoor heat exchanger and the outdoor heat exchanger 6 serve as a condenser or an evaporator. When the indoor heat exchanger serves as a condenser, the air conditioner serves as a heater in a heating mode, and when the indoor heat exchanger serves as an evaporator, the air conditioner serves as a cooler in a cooling mode.

[0082] The refrigeration cycle and the heating cycle include a compression process, a condensation process, an expansion process, and an evaporation process, and provide cold or heat to an indoor space by heat absorption and heat release processes of a refrigerant to achieve temperature adjustment of the indoor space.

[0083] The compressor compresses the refrigerant gas into a high-temperature and high-pressure state and discharges the compressed refrigerant gas, which flows into the condenser.

[0084] The condenser condenses the compressed high-temperature and high-pressure gaseous refrigerant into a liquid refrigerant, and heat is released to the surrounding environment through the condensation process.

[0085] The liquid refrigerant flowing out of the condenser enters the throttling device, which expands the high-temperature and high-pressure liquid refrigerant condensed by the condenser into a low-pressure liquid refrigerant.

[0086] The low-pressure liquid refrigerant flowing out of the throttling device enters the evaporator, and the liquid refrigerant absorbs heat and evaporates into a low-temperature and low-pressure refrigerant gas as it flows through the evaporator, and the low-temperature and low-pressure refrigerant gas returns to the compressor.

[0087] The evaporator can achieve a refrigeration effect by exchanging heat with a material to be cooled using the latent heat of evaporation of the refrigerant. In the entire cycle described above, the air conditioner can adjust the temperature of the indoor space.

[0088] Reference Figure 10 The cabinet 1 can include a chassis 16. The chassis 16 serves as a base of the air conditioner outdoor unit 100 to provide a mounting position for components such as the compressor, the outdoor heat exchanger 6, the outdoor fan 4, etc. The chassis 16 forms the bottom end of the cabinet 1.

[0089] The shell 1 can include a front panel 13 located at the front side of the shell 1. The air outlet 12 is formed on the front panel 13, so that the front side of the air conditioner outdoor unit 100 is the air outlet.

[0090] The shell 1 can include a rear panel 14 located at the rear side of the shell 1. The front panel 13 and the rear panel 14 are oppositely arranged along the thickness direction of the shell 1.

[0091] The shell 1 can include two side panels 15. The side panels 15 can be arranged between the front panel 13 and the rear panel 14. The two side panels 15 are respectively located at the left side and the right side of the shell 1.

[0092] Reference Figure 2 The air inlet 11 can be formed on the rear panel 14 and the side panel 15 at the left side of the shell 1, which increases the air inlet area and improves the air inlet volume.

[0093] Further, the outdoor heat exchanger 6 can be a plate type heat exchanger.

[0094] In the case of minimizing the size of the air conditioner outdoor unit 100, in order to increase the heat exchange area of the outdoor heat exchanger 6, the outdoor heat exchanger 6 can be arranged as an L-shaped heat exchanger. When the outdoor heat exchanger 6 is an L-shaped heat exchanger, the outdoor heat exchanger 6 is arranged corresponding to the air inlet side. That is, a part of the outdoor heat exchanger 6 corresponds to the air inlet 11 on the rear panel 14, and another part of the outdoor heat exchanger 6 corresponds to the air inlet 11 on the side panel 15 at the left side of the shell 1.

[0095] In some embodiments of the present application, the shell 1 includes a top panel 17, which is oppositely arranged with the bottom panel 16 and forms the top end of the shell 1. The front panel 13, the rear panel 14, the side panel 15, the top panel 17 and the bottom panel 13 form the installation cavity.

[0096] It should be noted that the directions described herein are based on the direction of the user facing the air conditioner outdoor unit 100, wherein the side of the air conditioner outdoor unit 100 facing the user during use is defined as the front side, and the opposite side is the rear side. The left side and the right side are distinguished from left to right in the direction of the user facing the air conditioner outdoor unit 100.

[0097] The air conditioner outdoor unit 100 can include a partition assembly arranged in the shell 1 along the height direction of the shell 1, so as to divide the installation cavity in the shell 1 into a fan cavity 18 and a compressor cavity 19.

[0098] The outdoor fan 4 is installed in the fan cavity 18, the outdoor heat exchanger 6 is installed in the fan cavity 18, and the compressor is installed in the compressor cavity 19.

[0099] The partition assembly separates the outdoor fan 4 from the compressor, reduces mutual interference between them, and improves the overall operation efficiency and reliability of the air conditioner outdoor unit 100.

[0100] The partition assembly is connected between the front panel 13 and the rear panel 14. This arrangement makes the installation of the partition assembly in the cabinet 1 more stable and can provide better support, ensuring that the partition assembly does not loosen or deform during long-term use, thereby ensuring the separation effect of the fan cavity 18 and the compressor cavity 19 and further improving the stability and reliability of the air conditioner outdoor unit 100.

[0101] Reference Figure 5 The partition assembly can include a middle partition 2 installed on the bottom plate 16. The middle partition 2 can be connected to the bottom plate 16 by screwing.

[0102] The middle partition 2 can include a first sub-plate 21, an arc plate 22, a second sub-plate 23, and a third sub-plate 24 arranged in sequence from front to back. The segmented middle partition 2 can be optimized in shape and size parameters according to the functional requirements of different parts.

[0103] The first sub-plate 21 is connected to the front panel 13. The connection of the first sub-plate 21 and the front panel 13 ensures the stability of the middle partition 2 on the side of the front panel 13.

[0104] The partition assembly can include an end plate 3 connected to the middle partition 2. The end plate 3 is connected to one end of the outdoor heat exchanger 6, and the end plate 3 is connected to the rear panel 14 of the cabinet 1.

[0105] Reference Figure 4 Connecting the middle partition 2 and the end plate 3 at one end of the outdoor heat exchanger 6 forms a good cooperation relationship between the partition assembly and the outdoor heat exchanger 6.

[0106] On the one hand, the end plate 3 can support and position the outdoor heat exchanger 6, ensuring that the outdoor heat exchanger 6 maintains a stable position and state during operation. On the other hand, the above arrangement is conducive to optimizing the uniformity of the velocity field distribution of the middle partition 2 at the junction of the outdoor heat exchanger 6, the airflow organization between the fan cavities 18, making the airflow pass through the heat exchanger more smoothly, improving the heat exchange efficiency, and reducing the additional energy loss and noise caused by airflow turbulence.

[0107] Reference Figure 5 , Figure 7 The center of the arc plate 22 is located in the compressor cavity 19, and the second sub-plate 23 extends from front to back away from the outdoor fan 4.

[0108] The partition plate 2 with the above structure optimizes the resistance influence of the partition plate 2 on the whole machine wind field through streamlined transition, has the characteristics of low whole machine resistance, high air volume, low noise and high installation efficiency, and the setting of the arc plate 22 and the second sub-plate 23 can better guide the airflow after heat exchange through the outdoor heat exchanger 6, make the airflow flow to the air outlet 12 more smoothly, reduce the vortex and resistance of the airflow near the arc plate 22, optimize the whole machine wind field, improve the air volume, reduce the noise caused by airflow turbulence, and improve the overall performance of the air conditioner outdoor unit 100.

[0109] Reference Figure 7 In the cross section perpendicular to the height direction of the cabinet 1, the radius of the arc plate 22 is R, wherein 0.08L≤R≤0.13L. L is the thickness dimension of the cabinet 1.

[0110] In this embodiment, the radius of the arc plate 22 is reasonably set on the basis of meeting the structural support requirements, the wind field speed at the arc plate 22 is optimized, the vorticity is reduced, and the performance of the outdoor fan 4 is improved, the air volume is improved, and the noise is reduced.

[0111] Further, with reference to Figure 7 In the cross section perpendicular to the height direction of the cabinet 1, the vertical distance between the two ends of the second sub-plate 23 away from the arc plate 22 is L3. Wherein, 0.10L≤L3≤0.48L.

[0112] By reasonably setting the vertical distance L3 of the structure formed by connecting the arc plate 22 and the second sub-plate 23, the flow speed at the outlet of the outdoor heat exchanger 6 is changed, the uniformity of the outdoor heat exchanger 6 wind field close to the side of the partition plate 2 is improved, the outdoor heat exchanger 6 air resistance is reduced, and the performance of the outdoor heat exchanger 6 is improved to some extent.

[0113] In some embodiments, the radius of the arc plate 22 is R. R≥0.08L. R≤0.13L.

[0114] The radius R cannot be too large, and too large radius R will squeeze the capacity of the right compressor cavity 19, and in severe cases, will cause installation interference of the compressor and its related components in the compressor cavity 19 and cannot be installed.

[0115] In order to avoid affecting the capacity of the compressor cavity 19, meet the space layout requirements inside the compressor cavity 19, set the radius R to be not greater than the first parameter value, and the first parameter value can be any value between 0.12L and 0.13L. A suitable specific parameter is selected in specific design. For example, the first parameter value can be 0.13L, which can reduce the occupation of the partition plate 2 to the space of the compressor cavity 19, and ensure that the compressor and its related components have enough installation space and good heat dissipation conditions.

[0116] The radius R cannot be too small, otherwise the transition of the circular-arc plate 22 is not smooth enough, vortexes and greater resistance are likely to be generated near the bending of the partition plate 2, the wind field is not uniform, the air volume and the fan efficiency are reduced, and the noise is increased.

[0117] In order to reduce the vorticity, improve the uniformity of the overall flow field, and improve the performance of the overall wind field, the radius R is set to be not less than a second parameter value. The second parameter value can be any value between 0.08L and 0.09L. In the specific design, a suitable specific parameter is selected. For example, the second parameter value can be 0.08L, which balances the optimization of the overall wind field performance and the guarantee of the capacity of the compressor cavity 19.

[0118] In some embodiments of the present application, in the cross section perpendicular to the height direction of the cabinet 1, the horizontal distance between the two ends of the second sub-plate 23 is W1. Wherein, 0.2L≤W1≤0.35L.

[0119] In the present embodiment, by reasonably setting the vertical distance between the two ends of the second sub-plate 23, the overall wind field is further optimized, the flow field is more uniform, the performance of the outdoor heat exchanger 6 is improved, and the capacity of the compressor cavity 19 can be effectively avoided.

[0120] In some embodiments of the present application, the horizontal distance between the two ends of the second sub-plate 23 is W1. W1≥0.2L. W1≤0.35L.

[0121] W1 cannot be too large, otherwise the W1 increases the resistance of the partition plate 2 to the airflow, the wind field is not uniform, the vortex and the resistance of the outdoor heat exchanger 6 are increased, and the airflow after heat exchange of the outdoor heat exchanger 6 is affected.

[0122] In order to improve the heat exchange performance of the outdoor heat exchanger 6, W1 is set to be not greater than a third parameter value, and the third parameter value can be any value between 0.34L and 0.35L. In the specific design, a suitable specific parameter is selected. For example, the third parameter value can be 0.35L, which can improve the uniformity of the outdoor heat exchanger 6 wind field, reduce the outdoor heat exchanger 6 wind resistance, and thus improve the performance of the outdoor heat exchanger 6.

[0123] W1 cannot be too small, otherwise the angle formed between the second sub-plate 23 and the axial direction of the outdoor fan is too small, the capacity of the right compressor cavity 19 is squeezed, and in severe cases, the installation of the compressor and related components in the compressor cavity 19 is interfered and cannot be installed.

[0124] In order to avoid the extrusion of the capacity of the press cavity 19, meet the space layout requirements inside the press cavity 19, W1 is set to be not less than the fourth parameter value. The fourth parameter value can be any value between 0.2L and 0.21L. In the specific design, a suitable specific parameter is selected. For example, the fourth parameter value can be 0.2L, which meets the space requirements of the press cavity 19.

[0125] In some embodiments, in the cross section perpendicular to the height direction of the cabinet 1, the vertical distance between the end of the third partition plate 24 away from the second partition plate 23 and the rear panel 14 is L1. 0.12L≤L1≤0.3L.

[0126] In this embodiment, by reasonably setting the vertical distance L1, the wind field distribution at the outlet of the outdoor heat exchanger 6 is more uniform, the wind resistance is reduced, and the heat exchange efficiency is improved.

[0127] In some embodiments of the present application, with reference to Figure 8 , the vertical distance between the end of the third partition plate 24 away from the second partition plate 23 and the rear panel 14 is L1. Wherein, L1≥0.12L. L1≤0.3L.

[0128] L1 cannot be too large, and too large L1 will occupy too much installation cavity space, affecting the installation and layout of other components. In order to meet the premise of reasonable internal space layout of the cabinet 1, L1 is set to be not greater than the fifth parameter value, and the fifth parameter value can be any value between 0.29L and 0.3L. In the specific design, a suitable specific parameter is selected. For example, the fifth parameter value can be 0.3L.

[0129] L1 cannot be too small, and too small will make the second partition plate 23 too close to the outdoor heat exchanger 6, affecting the air outlet of the outdoor heat exchanger 6, and further affecting the wind field distribution of the outdoor heat exchanger 6. In order to improve the wind field performance of the whole machine, L1 is set to be not less than the sixth parameter value. The sixth parameter value can be any value between 0.12L and 0.13L. In the specific design, a suitable specific parameter is selected. For example, the sixth parameter value can be 0.12L.

[0130] In some embodiments, the first partition plate 21 includes a straight line segment arranged perpendicularly to the front panel 13, and the length dimension of the straight line segment is L2, 0.4L≤L2≤0.6L.

[0131] In this embodiment, by reasonably setting the length dimension L2 of the straight line segment of the first partition plate 21, it can be ensured that the compressor has sufficient installation space, and interference between the partition plate 2 and the compressor during installation and operation is avoided.

[0132] In some embodiments of the present application, the length dimension of the straight line segment is L2. L2≥0.4L, L2≤0.6L.

[0133] L2 cannot be too large, and too large L2 will make L1 and L3 too small, which is not conducive to the improvement of the overall wind field performance. In order to not affect the overall wind field performance, L2 is set to be not greater than a seventh parameter value, and the seventh parameter value can be any value between 0.58L and 0.6L. In the specific design, a suitable specific parameter is considered to be selected. For example, the seventh parameter value can be 0.6L.

[0134] L2 cannot be too small, and too small will affect the capacity of the press chamber 19 and the layout of various components in the press chamber 19. In order to avoid affecting the capacity of the press chamber 19, L2 is set to be not less than an eighth parameter value. The eighth parameter value can be any value between 0.4L and 0.42L. In the specific design, a suitable specific parameter is considered to be selected. For example, the eighth parameter value can be 0.4L.

[0135] Reference Figure 8 , the plane where the second partition plate 23 is located forms an angle β with the axial direction of the outdoor fan. Among them, 50°≤β≤80°.

[0136] In this embodiment, by reasonably setting the angle β, the wind field performance of the overall machine is improved while avoiding affecting the capacity of the press chamber 19.

[0137] In some embodiments of the present application, the plane where the second partition plate 23 is located forms an angle β with the axial direction of the outdoor fan. Among them, β≥50°, β≤80°.

[0138] The angle β cannot be too large, and too large angle β will increase the hindrance of the partition plate 2 to the heat exchange flow at the outlet of the outdoor heat exchanger 6, affect the heat exchange efficiency of the outdoor heat exchanger 6, and is not conducive to the improvement of the performance of the overall wind field. In order to improve the overall wind field performance and the heat exchange performance of the outdoor heat exchanger 6, the angle β is set to be not greater than a ninth parameter value, and the ninth parameter value can be any value between 75° and 80°. In the specific design, a suitable specific parameter is considered to be selected. For example, the ninth parameter value can be 80°.

[0139] The angle β cannot be too small, and too small will affect the capacity of the press chamber 19 and the layout of various components in the press chamber 19. In order to avoid affecting the capacity of the press chamber 19, the angle β is set to be not less than a tenth parameter value. The tenth parameter value can be any value between 50° and 60°. In the specific design, a suitable specific parameter is considered to be selected. For example, the tenth parameter value can be 50°, or 60°.
