[0002] In the outdoor unit of the air conditioner in the related technology, an angle area is formed between the heat exchanger and the partition plate. The temperature distribution of the heat exchanger near the angle area is higher, and the gas flow in the angle area is restricted, resulting in low heat exchange efficiency and insufficient heat exchange of the heat exchanger in the angle area. Utility Model Content

[0003] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, one purpose of the utility model is to provide an air conditioner outdoor unit, which can improve the heat exchange efficiency of the outdoor heat exchanger and reduce the risk of stall of the fan assembly.

[0004] The utility model also provides an air conditioner with the air conditioner outdoor unit.

[0005] According to the first aspect of the present invention, the outdoor unit of an air conditioner comprises: a shell assembly, comprising a casing and a partition plate, wherein the partition plate is arranged in the casing and divides the inner cavity of the casing into a first chamber and a second chamber arranged in a first direction, and the casing has a first air inlet and an air outlet arranged opposite to each other in a second direction and connected to the first chamber; a fan assembly, arranged in the first chamber and comprising a wind wheel, wherein the wind wheel is arranged close to the air outlet; an outdoor heat exchanger, arranged in the first chamber and comprising a first heat exchange part, wherein the first heat exchange part and the wind wheel are arranged opposite to each other in the second direction, and the first heat exchange part is arranged close to the first air inlet; a compressor, arranged in the second chamber; wherein the plane on which the wind wheel faces the side of the first heat exchange part gradually deviates from the first heat exchange part in the first direction toward the direction close to the partition plate.

[0006] According to the air conditioner outdoor unit of the embodiment of the utility model, by limiting the plane where the wind wheel faces the first heat exchange part, gradually deviating from the first heat exchange part in the first direction toward the direction close to the partition plate, the flow direction of the air in the casing can be changed, so that the flow direction of the air flowing through the first heat exchange part of the outdoor heat exchanger forms a certain acute angle with the first heat exchange part, on the one hand, the time for the air flow to flow through the first heat exchange part of the outdoor heat exchanger can be extended, and the first heat exchange part of the outdoor heat exchanger can be subjected to long-term heat exchange. On the other hand, the air flow at the angle area formed by the first heat exchange part of the outdoor heat exchanger and the partition plate is more deviated from the partition plate than the scheme of the related art, reducing the limiting effect of the partition plate on the air flow, thereby speeding up the wind speed in the angle area, greatly improving the wind speed and wind field in the angle area, and solving the problem of low heat exchange efficiency of the outdoor unit heat exchanger in the angle area formed with the partition plate in the related art, thereby improving the heat exchange efficiency of the whole machine.

[0013] In some examples, the axial direction of the wind shielding ring is along the second direction, extending from the first air inlet portion to the air outlet portion in a direction away from the partition plate.

[0014] In some specific examples, the axial dimension of the wind shield ring gradually decreases in the first direction toward the dividing plate.

[0015] In some specific examples, the axial dimension of the part of the wind shield ring away from the partition plate is H1, the axial dimension of the part of the wind shield ring close to the partition plate is H2, the inner diameter of the wind shield ring is D, and the angle between the rotation axis of the wind wheel and the second direction is β; wherein H1=5mm~80mm, H2=H1+D×(tanβ) / 2.

[0016] In some examples, the overlap dimension of the wind shielding ring and the wind guide ring in the axial direction of the wind guide ring is 1 mm to 60 mm.

[0017] In some examples, a dimension of the gap in the radial direction of the air guide ring is 0.5-20 mm.

[0047] The embodiments of the present invention are described in detail below, and 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 only used to explain the present invention, and cannot be understood as limiting the present invention.

[0048] Reference below Figure 1-Figure 12 The air-conditioning outdoor unit 100 according to the embodiment of the utility model is described. The air-conditioning outdoor unit 100 here can be the air-conditioning outdoor unit 100 of a wall-mounted air conditioner, the air-conditioning outdoor unit 100 of a vertical air conditioner, the air-conditioning outdoor unit 100 of a ceiling air conditioner, a window air conditioner, etc.

[0049] like Figure 1-Figure 3 As shown, the air-conditioning outdoor unit 100 according to the embodiment of the present utility model includes a housing assembly 10 , a fan assembly 30 , an outdoor heat exchanger 20 and a compressor 40 .

[0050] The shell assembly 10 includes a casing 11 and a partition plate 12, the partition plate 12 is arranged in the casing 11, and the partition plate 12 divides the inner cavity of the casing 11 into a first chamber 101 and a second chamber 102, the first chamber 101 and the second chamber 102 are arranged in a first direction, the casing 11 has a first air inlet portion 1031 and an air outlet portion 104, the first air inlet portion 1031 and the air outlet portion 104 are both connected to the first chamber 101, and the first air inlet portion 1031 and the air outlet portion 104 are relatively arranged in the second direction.

[0051] For example, the shape of the housing 11 may be a rectangular parallelepiped, and the first direction may be the length direction of the housing 11 (eg Figure 2 and Figure 3 The second direction may be the width direction of the housing 11 (eg, Figure 2 and Figure 3 In the front-to-rear direction shown in the figure), the first air inlet 1031 can be arranged on the rear wall of the casing 11 and the air outlet 104 can be arranged on the front wall of the casing 11, or the first air inlet 1031 can be arranged on the front wall of the casing 11 and the air outlet 104 can be arranged on the rear wall of the casing 11.

[0052] Furthermore, the partition plate 12 extends from the front wall of the housing 11 to the rear wall of the housing 11, so that the inner cavity of the housing 11 can be divided into a first chamber 101 and a second chamber 102 arranged in the left-right direction. The first chamber 101 can be located on the left side of the second chamber 102, or the first chamber 101 can be located on the left side of the second chamber 102.

[0053] Of course, the shape of the housing 11 may also be other shapes, which can be selected according to actual conditions.

[0054] The fan assembly 30 and the outdoor heat exchanger 20 are both disposed in the first chamber 101. The fan assembly 30 includes a wind wheel 31, which is disposed near the air outlet 104. The outdoor heat exchanger 20 includes a first heat exchange portion 21, the first heat exchange portion 21 and the wind wheel 31 are disposed opposite to each other in the second direction, and the first heat exchange portion 21 is disposed near the first air inlet 1031. The compressor 40 is disposed in the second chamber 102.

[0055] When the air conditioner is working, the compressor 40 compresses the refrigerant, and the high-temperature and high-pressure gas flowing out of the compressor 40 flows through the outdoor heat exchanger 20, and combines with the indoor heat exchanger of the air conditioner indoor unit to achieve air conditioning. Among them, when the wind wheel 31 of the air conditioner outdoor unit 100 rotates, the external air of the air conditioner outdoor unit 100 forms an airflow under the drive of the wind wheel 31, and enters the casing 11 through the first air inlet 1031, exchanges heat with the outdoor heat exchanger 20, and finally is discharged from the air outlet 104 to the outside of the air conditioner outdoor unit 100.

[0056] The plane 313 where the wind wheel 31 faces one side of the first heat exchange portion 21 gradually deviates from the first heat exchange portion 21 in the first direction toward the direction close to the partition plate 12 .

[0057] like Figure 2 As shown, the blade tips 312 of the multiple blades 311 of the wind wheel 31 are arranged toward the first heat exchange part 21, and the plane 313 where the side of the wind wheel 31 facing the first heat exchange part 21 is located is the plane 313 where the blade tips 312 of the multiple blades 311 of the wind wheel 31 are located.

[0058] For easier understanding, please continue to refer to Figure 2 In an embodiment where the first chamber 101 is located on the left side of the second chamber 102, the first air inlet 1031 is provided on the rear wall of the casing 11, and the air outlet 104 is provided on the front wall of the casing 11, the plane 313 where the blade tips 312 of the multiple blades 311 of the wind wheel 31 are located is gradually inclined forward from left to right.

[0059] Specifically, during the rotation of the wind wheel 31, the air entering the housing 11 from the first air inlet 1031 can flow from one axial end of the wind wheel 31 to the other axial end, and finally be discharged from the air outlet 104. Since the plane 313 where the blade tips 312 of the plurality of blades 311 of the wind wheel 31 are located gradually deviates from the first heat exchange part 21 in the first direction toward the direction close to the partition plate 12, the air entering the housing 11 from the first air inlet 1031 flows from the first air inlet 1031 to the air outlet 104 in the second direction away from the partition plate 12, so that the flow direction of the air near the first air inlet 1031 forms a certain acute angle with the first heat exchange part 21, rather than a right angle, thereby changing the local wind speed and wind field distribution of the outdoor heat exchanger 20, that is, changing the wind speed and wind field distribution of the first extension part of the outdoor heat exchanger 20, and strengthening the heat dissipation field in the high temperature area of ​​the first heat exchange part 21.

[0060] According to the air-conditioning outdoor unit 100 of the utility model embodiment, by limiting the plane 313 on one side of the wind wheel 31 facing the first heat exchange part 21, gradually deviating from the first heat exchange part 21 in a first direction toward the direction close to the partition plate 12, the flow direction of the air in the casing 11 can be changed, so that the flow direction of the air flowing through the first heat exchange part 21 of the outdoor heat exchanger 20 forms a certain acute angle with the first heat exchange part 21. On the one hand, the time for the airflow to flow through the first heat exchange part 21 of the outdoor heat exchanger 20 can be extended, so as to perform long-term heat exchange on the first heat exchange part 21 of the outdoor heat exchanger 20.

[0061] On the other hand, the angle area formed by the first heat exchange portion 21 of the outdoor heat exchanger 20 and the partition plate 12 (such as Figure 2 The airflow at the inefficient heat exchange area (indicated by the circular circle in the figure) deviates further from the partition plate 12 than in the related art, reducing the restrictive effect of the partition plate 12 on the airflow, thereby accelerating the wind speed in the angle area, greatly improving the wind speed and wind field in the angle area, and solving the problem of low heat exchange efficiency of the outdoor unit heat exchanger in the related art in the angle area formed with the partition plate 12, thereby improving the heat exchange efficiency of the entire machine.

[0062] In addition, the airflow can also form a certain acute angle with the casing 11 in the outlet direction of the air outlet portion 104, rather than a right angle, thereby reducing the risk of the fan assembly 30 stalling due to the external airflow flowing back into the casing 11 when the wind blows.

[0063] like Figure 2 As shown, according to some embodiments of the present utility model, the angle α between the plane 313 on the side of the wind wheel 31 facing the first heat exchange part 21 and the first heat exchange part 21 is 0.1°~20°. For example, the angle α between the plane 313 on the side of the wind wheel 31 facing the first heat exchange part 21 and the first heat exchange part 21 can be 0.1°, 1°, 3°, 5°, 10°, 14°, 18°, 20°, etc.

[0064] If the angle α between the plane 313 on the side of the wind wheel 31 facing the first heat exchange part 21 and the first heat exchange part 21 is too large, the size of the wind wheel 31 in the second direction will increase, thereby increasing the size of the air conditioner outdoor unit 100 in the second direction.

[0065] Therefore, in the above technical solution, by limiting the angle α between the plane 313 on the side of the wind wheel 31 facing the first heat exchange part 21 and the first heat exchange part 21 to satisfy the above range, the size of the air-conditioning outdoor unit 100 in the second direction can be reduced on the basis of ensuring the heat exchange efficiency of the first heat exchange part 21, which is conducive to realizing the miniaturized structural design of the air-conditioning outdoor unit 100.

[0066] like Figure 2-Figure 3 As shown, according to some embodiments of the utility model, the rotation axis 332 of the wind wheel 31 extends along the second direction from the first air inlet 1031 to the air outlet 104 in a direction deviating from the partition plate 12. Therefore, the air entering the casing 11 from the first air inlet 1031 flows in the second direction from the first air inlet 1031 to the air outlet 104 in a direction deviating from the partition plate 12. In this way, the flow direction of the air near the first air inlet 1031 can form a certain acute angle with the first heat exchange part 21, rather than a right angle, thereby changing the local wind speed and wind field distribution of the outdoor heat exchanger 20, that is, changing the wind speed and wind field distribution of the first extension part of the outdoor heat exchanger 20, and strengthening the heat dissipation field in the high temperature area of ​​the first heat exchange part 21.

[0067] Among them, Figure 4-Figure 7 As shown, the fan assembly 30 further includes an air guide ring 32 , which surrounds the outer circumference of the wind wheel 31 , and the air guide ring 32 is integrally connected to the plurality of blades 311 of the wind wheel 31 .

[0068] Therefore, by setting the air guide ring 32, on the one hand, the guide effect can be achieved, so that the air in the casing 11 can flow toward the air outlet 104 under the action of the wind wheel 31 and the guidance of the air guide ring 32, thereby increasing the air flow rate in the casing 11 and improving the heat exchange efficiency. On the other hand, the air guide ring 32 can connect multiple blades 311 together, improve the structural strength of the blades 311, and reduce the problem of deformation of the blades 311.

[0069] like Figure 7 and Figure 8 As shown, in some embodiments, the axial dimension H0 of the air guide ring 32 is 2 mm to 70 mm. The axial direction of the air guide ring 32 may extend along the axial direction of the wind wheel 31, and the axial dimension of the air guide ring 32 is the dimension of the air guide ring 32 in the axial direction of the wind wheel 31. For example, the axial dimension H0 of the air guide ring 32 may be 2 mm, 5 mm, 10 mm, 20 mm, 30 mm, 40 mm, 50 mm, 60 mm, 70 mm, etc.

[0070] If the axial dimension of the air guide ring 32 is too large, the weight of the combined structure of the wind wheel 31 and the air guide ring 32 will increase, causing the wind wheel 31 to swing significantly along the radial direction of the wind wheel 31 during rotation, which not only affects the matching relationship between the combined structure of the wind wheel 31 and the air guide ring 32 and nearby components, but also affects the wind speed and wind field distribution near the wind wheel 31; if the axial dimension of the air guide ring 32 is too small, the guide effect of the air guide ring 32 will be affected.

[0071] Therefore, in the above technical solution, by limiting the axial dimension H0 of the air guide ring 32 to satisfy the above range, the air guiding effect of the air guide ring 32 and the weight of the combined structure of the wind wheel 31 and the air guide ring 32 can be balanced. On the basis of ensuring the air guiding effect, the weight of the combined structure of the wind wheel 31 and the air guide ring 32 can be made as small as possible.

[0072] like Figure 3 and Figure 4 As shown, in some embodiments, the casing 11 includes a mounting panel 116, the air outlet 104 is disposed on the mounting panel 116, and the motor 33 of the fan assembly 30 is mounted on the mounting panel 116, that is, there is no need to separately set a mounting bracket for the motor 33 in the casing 11, but the motor 33 is directly mounted on the mounting panel 116 of the casing 11, thereby reducing the number of components of the air-conditioning outdoor unit 100 and reducing costs.

[0073] The mounting panel 116 has a wind shielding ring 1163 , which surrounds the air outlet 104 and is sleeved on the outside of the air guide ring 32 . A gap 320 is defined between the wind shielding ring 1163 and the air guide ring 32 .

[0074] The air guide ring 32 and the wind shielding ring 1163 can cooperate with each other so that when the wind wheel 31 is rotating, external air enters the casing 11 from the first air inlet 1031, passes through the outdoor heat exchanger 20, and flows toward the air outlet 104 under the action of the wind wheel 31. The air guide ring 32 and the wind shielding ring 1163 can gather the airflow to the air outlet 104, reduce the return air flowing to the wind wheel 31, and thereby reduce the impact of the return air on the wind wheel 31.

[0075] In addition, there is a gap 320 between the wind shield ring 1163 and the air guide ring 32, so that when the wind wheel 31 rotates relative to the installation panel 116, the air guide ring 32 can avoid collision with the wind shield ring 1163 of the installation panel 116, thereby avoiding collision between the wind wheel 31 and the installation panel 116.

[0076] like Figure 4-Figure 7 As shown, in some examples, the mounting panel 116 includes a panel body 1161, a bracket 1162 and a protective cover 1165, the panel body 1161 has a vent 1161a, a wind shield ring 1163 is located inside the panel body 1161, and the wind shield ring 1163 extends along the circumference of the vent 1161a, the bracket 1162 is provided at the vent 1161a, the bracket 1162 is connected to the wind shield ring 1163, for example, the bracket 1162 can be connected to the wind shield ring 1163 only, or the bracket 1162 can be connected to the panel body 1161 and the wind shield ring 1163. The motor 33 is mounted on the bracket 1162, the protective cover 1165 is detachably provided on the panel body 1161, and the protective cover 1165 covers the vent 1161a, and the air outlet 104 is provided on the protective cover 1165.

[0077] When assembling the air conditioner outdoor unit 100, the motor 33 can be first installed on the bracket 1162, and then the panel body 1161 is connected with other components of the housing 11, and finally the protective cover 1165 is installed on the panel body 1161. Of course, the panel body 1161 can also be connected with other components of the housing 11, and then the motor 33 is installed on the bracket 1162, and finally the protective cover 1165 is installed on the panel body 1161. If the motor 33 needs to be repaired, the protective cover 1165 can be removed first, and then the panel body 1161 or the motor 33 can be removed to repair the motor 33. Therefore, by setting the mounting panel 116 into the above structure, the installation, disassembly and maintenance of the motor 33 are convenient.

[0078] In addition, a wind shield ring 1163 and a bracket 1162 are arranged on the inner side of the panel body 1161. The bracket 1162 can be used to support and fix the motor 33. The wind shield ring 1163 is arranged on the periphery of the bracket 1162. On the one hand, the structural strength of the bracket 1162 can be increased, thereby improving the installation reliability and stability of the motor 33. On the other hand, it can cooperate with the air guide ring 32 so that the wind wheel 31 can gather the airflow to the air outlet 104 during the rotation of the wind wheel 31, thereby reducing the return air flowing to the wind wheel 31, and further reducing the impact of the return air on the wind wheel 31.

[0079] The panel body 1161, the bracket 1162 and the wind shield ring 1163 are integrally formed. The integrally formed structure can not only improve the structural strength of the mounting panel 116, thereby improving the anti-deformation ability of the mounting panel 116, but also reduce the number of components and the assembly steps of the air conditioner outdoor unit 100, thereby improving the production efficiency of the air conditioner outdoor unit 100.

[0080] like Figure 7 As shown, in some examples, the axial direction of the wind shielding ring 1163 is along the second direction, extending from the first air inlet portion 1031 to the air outlet portion 104 in a direction deviating from the partition plate 12 .

[0081] With such an arrangement, the axial direction of the motor 33 can be tilted relative to the second direction, thereby making the axial direction of the wind wheel 31 tilted relative to the second direction and the protective cover 1165. In this way, the air entering the casing 11 from the first air inlet 1031 flows in the second direction from the first air inlet 1031 to the air outlet 104 in a direction away from the partition plate 12, so that the flow direction of the air near the first air inlet 1031 forms a certain acute angle with the first heat exchange part 21, rather than a right angle, thereby changing the local wind speed and wind field distribution of the outdoor heat exchanger 20, that is, changing the wind speed and wind field distribution of the first extension part of the outdoor heat exchanger 20, and strengthening the heat dissipation field in the high temperature area of ​​the first heat exchange part 21.

[0082] like Figure 7-Figure 9 As shown, in some specific examples, the axial dimension of the wind shielding ring 1163 gradually decreases in the first direction toward the direction close to the partition plate 12. That is, the axial dimensions of the wind shielding ring 1163 at different positions on its circumference are not equal.

[0083] Specifically, in an embodiment in which the first chamber 101 is located on the left side of the second chamber 102, the first air inlet 1031 is provided on the rear wall of the casing 11, and the air outlet 104 is provided on the front wall of the casing 11, the axial direction of the wind shield ring 1163 extends obliquely to the right from front to back, and the axial dimension of the wind shield ring 1163 gradually decreases from left to right, the axial dimension of the leftmost part of the wind shield ring 1163 is H1, and the axial dimension of the rightmost part of the wind shield ring 1163 is H2, and H1 is greater than H2.

[0084] In the above technical scheme, the above conditions are met by limiting the axial size of the wind shield ring 1163. The axial direction of the wind shield ring 1163 can be tilted relative to the second direction and the first direction, so that the axial direction of the motor 33 and the wind wheel 31 can be tilted relative to the second direction. In this way, the air entering the casing 11 from the first air inlet 1031 flows in the second direction from the first air inlet 1031 to the air outlet 104 in a direction away from the partition plate 12, so that the flow direction of the air near the first air inlet 1031 forms a certain acute angle with the first heat exchange part 21, rather than a right angle, thereby changing the local wind speed and wind field distribution of the outdoor heat exchanger 20 and strengthening the heat dissipation field in the high temperature area of ​​the first heat exchange part 21.

[0085] like Figure 7-Figure 9 As shown, in some specific examples, the axial dimension of the portion of the wind shield ring 1163 away from the partition plate 12 is H1, and the axial dimension of the portion of the wind shield ring 1163 close to the partition plate 12 is H2. That is, the distance between the portion of the wind shield ring 1163 away from the partition plate 12 and the panel body 1161 and the panel body 1161 is H1, and the distance between the portion of the wind shield ring 1163 close to the partition plate 12 and away from the panel body 1161 and the panel body 1161 is H2.

[0086] The inner diameter of the wind shield ring 1163 is D, and the angle between the rotation axis 332 of the wind wheel 31 and the second direction is β. Wherein, H1 is 5 mm to 80 mm, for example, the axial dimension H1 of the portion of the wind shield ring 1163 away from the partition plate 12 can be 5 mm, 10 mm, 20 mm, 40 mm, 60 mm, 80 mm, etc., and H2=H1+D×(tanβ) / 2, that is, H2 is equal to half of the product of D and tanβ, and the sum of H1.

[0087] Therefore, by limiting the axial dimension H1 of the part of the wind shield ring 1163 away from the partition plate 12, the axial dimension H2 of the part of the wind shield ring 1163 close to the partition plate 12, the inner diameter D of the wind shield ring 1163, and the angle β between the rotation axis 332 of the wind wheel 31 and the second direction to meet the above conditions, the first heat exchange part 21 of the outdoor heat exchanger 20 can better perform long-term heat exchange and improve the heat exchange efficiency of the whole machine.

[0088] It should be noted that the degree of fit between the wind shielding ring 1163 and the wind guide ring 32, that is, the size of the gap 320 between the wind shielding ring 1163 and the wind guide ring 32, determines the leakage of the airflow.

[0089] like Figure 7-Figure 9As shown, in some examples, the dimension L of the overlap between the wind shielding ring 1163 and the wind guide ring 32 in the axial direction of the wind guide ring 32 is 1 mm to 60 mm. For example, the dimension L of the overlap between the wind shielding ring 1163 and the wind guide ring 32 in the axial direction of the wind guide ring 32 can be 1 mm, 5 mm, 10 mm, 15 mm, 20 mm, 25 mm, 30 mm, 35 mm, 40 mm, 45 mm, 50 mm, 55 mm, 60 mm, etc.

[0090] In the above technical solution, the above conditions are met by limiting the overlapping dimension L of the wind shield ring 1163 and the air guide ring 32 in the axial direction of the air guide ring 32, thereby preventing the air guide ring 32 from being disengaged from the wind shield ring 1163 when it jumps along its axial direction, thereby reducing airflow leakage.

[0091] In order to further reduce airflow leakage, the smaller the size of the gap 320S between the wind shield ring 1163 and the wind guide ring 32 in the radial direction of the wind guide ring 32, the better. Therefore, under the condition that the size of the wind shield ring 1163 is the same, the larger the radial size of the wind wheel 31 and the wind guide ring 32, the smaller the size of the gap 320S between the wind shield ring 1163 and the wind guide ring 32 in the radial direction of the wind guide ring 32, and the gas flow in the housing 11 can be greatly improved.

[0092] However, considering the manufacturing process level, such as Figure 7 and Figure 8 As shown, in some examples, the size S of the gap 320 in the radial direction of the air guide ring 32 is 0.5 mm to 20 mm. For example, the size S of the gap 320 in the radial direction of the air guide ring 32 can be 0.5 mm, 1 mm, 5 mm, 10 mm, 14 mm, 18 mm, 20 mm, etc.

[0093] With such an arrangement, while ensuring the gas flow in the casing 11, the manufacturing difficulty of the air guide ring 32 and the wind shield ring 1163 of the installation panel 116 can be reduced, thereby avoiding a collision between the air guide ring 32 and the wind shield ring 1163 of the installation panel 116, and further avoiding a collision between the wind wheel 31 and the installation panel 116.

[0094] like Figure 2 and Figure 3 As shown, according to a further embodiment of the utility model, the partition plate 12 includes a first partition portion 121 and a second partition portion 122, the first partition portion 121 extends along the second direction, and the second partition portion 122 is connected to the wall where the air outlet portion 104 is located, the second partition portion 122 extends along the second direction from the air outlet portion 104 to the first air inlet portion 1031 in a direction away from the wind wheel 31, and the second partition portion 122 is located between the first partition portion 121 and the first heat exchange portion 21.

[0095] The partition plate 12 can separate the inner cavity of the casing 11 into a first chamber 101 and a second chamber 102, so that components such as the outdoor heat exchanger 20, the fan assembly 30, and the compressor 40 can be arranged in partitions, which is beneficial to ensuring the working stability of the air-conditioning outdoor unit 100.

[0096] In the above technical solution, by setting the partition plate 12 as the above structure, on the one hand, the volume of the first chamber 101 can be increased, thereby increasing the volume of the outdoor heat exchanger 20, which is beneficial to improving the working efficiency of the air conditioner. The volume of the second chamber 102 can also be reduced, and the utilization rate of the internal space of the casing 11 can be improved. On the other hand, the air capacity of the first chamber 101 can be increased, thereby improving the heat exchange efficiency between the air and the outdoor heat exchanger 20, improving the heat dissipation effect, avoiding overloading of the unit, appropriately reducing power consumption, and improving the energy-saving effect of the air conditioner.
