Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0063] In the prior art, the air conditioner outdoor unit includes a partition, which can divide the accommodation space into two cavities, namely, an air duct cavity for accommodating an outdoor fan and an accommodation cavity for accommodating a compressor. In order to ensure that the outdoor heat exchanger has a sufficient heat exchange area, the outdoor heat exchanger is set as large as possible, and some outdoor heat exchangers are set behind the accommodation cavity. Since the partition is connected to the end of the outdoor heat exchanger, the projection area of ​​the partition on the outdoor heat exchanger in the air inlet direction of the outdoor heat exchanger is approximately the projection area of ​​the accommodation cavity on the outdoor heat exchanger in the air inlet direction of the outdoor heat exchanger. That is, the setting of the partition will block the flow of airflow in the airflow direction, affect the flow speed and flow rate of the airflow, resulting in low heat exchange efficiency of the heat exchanger and affecting the heat exchange effect of the heat exchanger.

[0064] To this end, the embodiment of the utility model designs an air-conditioning outdoor unit 1000 in which the portion of the outdoor heat exchanger 2 opposite to the partition 6 is bent toward the direction close to the outdoor fan 3, thereby changing the air inlet direction of the portion of the outdoor heat exchanger 2 opposite to the partition 6, thereby reducing the projection area of ​​the partition on the outdoor heat exchanger 2 in the air inlet direction, reducing the influence of the partition 6 on the air flow velocity and flow rate, avoiding the influence of the partition setting on the air flow velocity, and improving the heat exchange effect of the outdoor heat exchanger 2.

[0065] Reference below Figure 1-Figure 17 An air conditioner outdoor unit 1000 according to an embodiment of the present invention is described.

[0066] like Figure 1-Figure 17 As shown, the air conditioner outdoor unit 1000 includes a casing 1, an outdoor heat exchanger 2, an outdoor fan 3 and a partition 6.

[0067] The housing 1 defines a receiving space 100, and the outdoor fan 3 is disposed in the receiving space 100 to drive air to form an airflow. The outdoor heat exchanger 2 is disposed in the receiving space 100, and the airflow will flow through the outdoor heat exchanger 2 during the flow process. The outdoor heat exchanger 2 includes an air inlet side and an air outlet side.

[0068] The partition 6 and the outdoor fan 3 are arranged side by side on the air outlet side of the outdoor heat exchanger 2, that is, the partition 6 and the outdoor fan 3 are arranged downstream of the outdoor heat exchanger 2. The partition 6 is connected to the outdoor heat exchanger 2 to divide the accommodating space 100 into an air duct cavity 20 for accommodating the outdoor fan 3 and an accommodating cavity 30 for accommodating the compressor 90. The airflow flows into the air duct cavity 20 through the outdoor heat exchanger 2, and the flow direction of the airflow after passing through the outdoor heat exchanger 2 is perpendicular to the outdoor heat exchanger 2.

[0069] The partition 6 can separate the outdoor fan 3 from the compressor 90 to avoid interference between the operation of the outdoor fan 3 and the compressor 90 and structures such as connecting pipes and connecting lines arranged in the accommodating chamber 30.

[0070] In order to ensure that the outdoor heat exchanger 2 has a sufficient heat exchange area, the outdoor heat exchanger 2 is set as large as possible, so part of the outdoor heat exchanger 2 is set behind the accommodating chamber 30, and because the partition 6 is connected to the end of the outdoor heat exchanger 2, the projection area of ​​the partition on the outdoor heat exchanger 2 is large in the air inlet direction of the outdoor heat exchanger 2. The partition 6 will block the airflow in the direction of airflow flow, affecting the flow speed and flow rate of the airflow, resulting in low heat exchange efficiency of the outdoor heat exchanger 2, affecting the heat exchange effect of the outdoor heat exchanger 2.

[0071] Among them, the part of the outdoor heat exchanger 2 opposite to the partition 6 is bent toward the direction close to the outdoor fan 3 to form a first heat exchange part 21, so as to change the flow direction of the airflow after passing through the first heat exchange part 21 of the outdoor heat exchanger 2, increase the angle between the partition 6 and the first heat exchange part 21, and reduce the projection area of ​​the partition 6 on the outdoor heat exchanger 2 in the gas flow direction, thereby avoiding the setting of the partition 6 affecting the airflow flow speed and improving the heat exchange effect of the outdoor heat exchanger 2.

[0072] According to the air-conditioning outdoor unit 1000 of the embodiment of the utility model, the internal structure of the air-conditioning outdoor unit 1000 is more reasonably arranged, the internal air flow speed is faster, the gas flow passing through the outdoor heat exchanger 2 is larger, the heat exchange efficiency of the outdoor heat exchanger 2 is higher, and the heat exchange effect is better.

[0073] Reference Figure 6 The partition 6 includes: a first partition 62 and a connecting plate 61, wherein the connecting plate 61 is connected to one side of the first partition 62 in the width direction, and the first partition 62 and the connecting plate 61 separate the two cavities between the installation cavity 10 and the air duct cavity 20, wherein the first partition 62 is mainly arranged between the compressor 90 and the outdoor fan 3 to separate the two to avoid interference between the structures in the two cavities, and the connecting plate 61 can mainly realize the function of connecting the partition 6 and the outdoor heat exchanger 2 together, and the first partition 62 is connected to the outdoor heat exchanger 2 through the connecting plate 61, and the connecting flange 72 of the outdoor heat exchanger 2 is connected to the connecting plate 61 of the partition 6, and the contact area between the outdoor heat exchanger 2 and the partition 6 can be increased by the cooperation of the connecting flange 72 and the connecting plate 61 of the partition 6, so that the connection between the partition 6 and the outdoor heat exchanger 2 is more stable, and a position that can be used for installation and connection is provided between the outdoor heat exchanger 2 and the partition 6 with different extension directions.

[0074] Among them, the first partition 62 is arranged opposite to the first heat exchange part 21. The first partition 62 can guide the airflow entering the air duct cavity 20 through the first heat exchange part 21, guide it to the outdoor fan, control the flow direction of the airflow in the air duct cavity 20, and ensure the flow rate of the airflow in the air duct cavity 20.

[0075] Furthermore, in order to avoid the partition from blocking the flow of air and affecting the heat exchange performance of the outdoor heat exchanger 2, the angle α between the first partition 62 and the first heat exchange part 21 is not less than 70°, so as to reduce the projection of the partition on the outdoor heat exchanger 2 in the air inlet direction and avoid the partition from affecting the air flow rate.

[0076] In addition, the angle α between the first partition 62 and the first heat exchange part 21 is not greater than 90°, so as to avoid the angle between the partition and the first heat exchange part 21 occupying a larger space inside the air-conditioning outdoor unit 1000 and affecting the space size of the accommodating cavity 30, thereby making the internal structure of the casing 1 more compact and helping to reduce the volume of the air-conditioning outdoor unit 1000.

[0077] In some embodiments, one side of the connecting plate 61 in the thickness direction is connected to the side plate 7 of the outdoor heat exchanger 2 to make the connection area larger, which is beneficial to improving the stability of the connection between the connecting plate 61 and the side plate 7 of the outdoor heat exchanger 2.

[0078] like Figure 6 As shown, the partition 6 also includes: a second partition 63, the two sides of the second partition 63 in the width direction are respectively connected to the casing 1 and the other side of the first partition 62 in the width direction, the second partition 63 is mainly arranged between the compressor 90 and the outdoor fan 3 to isolate the two. In some embodiments, the extension direction of the second partition 63 is parallel to the axial direction of the outdoor fan 3, the first partition 62 is connected to the second partition 63, and can jointly separate the accommodating space 100 into the air duct cavity 20 and the accommodating cavity 30.

[0079] Since part of the structure of the outdoor heat exchanger 2 is arranged behind the compressor 90, the second partition 63 is arranged between the compressor 90 and the outdoor fan 3, and the first partition 62 is connected to the end of the outdoor heat exchanger 2 and the end of the second partition 63 at the same time, therefore, the width direction of the first partition 62 connecting the second partition 63 and the end of the outdoor heat exchanger 2 is inclined relative to the width direction of the second partition 63, so that the first partition 62 can connect the second partition 63 and the outdoor heat exchanger 2 which are staggered at the end.

[0080] Reference Figure 2 , Figure 7 , Fig. 9 and Fig.15 The outdoor heat exchanger 2 also includes: a main heat exchange part 22, which is arranged opposite to a side wall of the casing 1, and the main heat exchange part 22 is arranged close to the air inlet 101 on the casing 1. Part of the airflow entering the accommodating space 100 from the air inlet 101 can directly exchange heat with the main heat exchange part 22.

[0081] The first heat exchange part 21 is connected to one side of the width direction of the main heat exchange part 22, and the width direction of the first heat exchange part 21 is inclined relative to the width direction of the main heat exchange part 22. Therefore, the first heat exchange part 21 and the air inlet part 101 are spaced apart, thereby forming a space upstream of the first heat exchange part 21. The airflow passing through the space does not pass through the heat exchange of the outdoor heat exchanger 2, and the temperature is lower. Structures that need heat dissipation, such as the electric control box 4, can be arranged between the first heat exchange part 21 and the air inlet part 101 to obtain a better heat dissipation effect.

[0082] In some embodiments, the main heat exchange portion 22 is disposed opposite to the rear wall of the casing 1 .

[0083] The outdoor heat exchanger 2 also includes a second heat exchange portion 23, which is connected to the other side of the main heat exchange portion 22 in the width direction, so that the outdoor heat exchanger 2 has a larger heat exchange area, thereby improving the heat exchange efficiency of the outdoor heat exchanger 2. The second heat exchange portion 23 is arranged opposite to the other side wall of the casing 1. In some embodiments, the second heat exchange portion 23 is arranged opposite to the left side wall or the right side wall of the casing 1 to ensure that the second heat exchange portion 23 can directly exchange heat with the fresh airflow entering the accommodating space 100 from the air inlet portion 101 arranged on the side wall of the casing 1, thereby improving the heat exchange effect.

[0084] In some embodiments, the outdoor heat exchanger 2 only includes a main heat exchange part 22 and a first heat exchange part 21, so that the volume of the air-conditioning outdoor unit 1000 is smaller. In other embodiments, the outdoor heat exchanger 2 includes a main heat exchange part 22, a first heat exchange part 21 and a second heat exchange part 23, so that the outdoor heat exchanger 2 has a larger heat exchange area and the air conditioner has better performance.

[0085] Reference Figure 2 , Figure 7 , Fig. 9 and Fig.15 The main heat exchange part 22 is arranged opposite to the rear side wall of the casing 1, so that at least part of the airflow entering the accommodating space 100 through the air inlet part 101 on the rear side wall of the casing 1 can directly contact the main heat exchange part 22 after entering the accommodating space 100, and exchange heat with the main heat exchange part 22. The airflow temperature around the main heat exchange part 22 is lower, the heat exchange efficiency of the main heat exchange part 22 is higher, and the heat exchange effect is better.

[0086] The first heat exchange part 21 extends forwardly and obliquely in a direction away from the main heat exchange part 22. On the one hand, it can change the flow direction of the airflow passing through the first heat exchange part 21, avoid the projection area of ​​the partition on the first heat exchange part 21 in the air inlet direction being too large, avoid the setting of the partition affecting the airflow speed, and improve the heat exchange effect of the outdoor heat exchanger 2.

[0087] On the other hand, the first heat exchange part 21 extends forwardly and obliquely in a direction away from the main heat exchange part 22, so that the first heat exchange part 21 and the air inlet part 101 are arranged at a distance, thereby forming a space upstream of the first heat exchange part 21. The airflow passing through the space does not pass through the heat exchange of the outdoor heat exchanger 2, and the temperature is lower. Structures that require heat dissipation, such as the electrical control box 4, can be arranged between the first heat exchange part 21 and the air inlet part 101 to obtain a better heat dissipation effect.

[0088] Reference Fig. 9 The partition 6 is connected between the front side wall of the casing 1 and the side of the first heat exchange part 21 away from the main heat exchange part 22 to ensure that the outdoor heat exchanger 2 is located as a whole in the air duct cavity 20 formed after the partition 6, to ensure that air flows through all parts of the outdoor heat exchanger 2, and to avoid the air flow passing through the gap between the partition and the outdoor heat exchanger 2, resulting in a reduction in the air flow passing through the outdoor heat exchanger 2, affecting the heat exchange effect and heat exchange efficiency of the outdoor heat exchanger 2.

[0089] like Fig. 9 As shown, the air conditioner outdoor unit 1000 further includes an electric control box 4, which is disposed on the side of the first heat exchange portion 21 facing away from the partition 6, that is, the electric control box 4 is disposed upstream of the first heat exchange portion 21. Therefore, on the one hand, the electric control box 4 can utilize the airflow driven by the outdoor fan 3, avoiding the need to provide an independent structure outside the outdoor fan 3 for airflow driving during the heat dissipation process of the electric control box 4, thereby reducing production costs.

[0090] On the other hand, in the process of the airflow flowing from the air inlet 101 to the air outlet 102 driven by the outdoor fan 3, at least part of the airflow first passes through the installation cavity 10, and the airflow dissipates the heat for the electric control box 4 in the installation cavity 10, and then exchanges heat with the outdoor heat exchanger 2 through the outdoor heat exchanger 2. Since part of the airflow flowing through the installation cavity 10 is not subjected to heat exchange by the outdoor heat exchanger 2, the temperature is relatively low, that is, the temperature of the airflow passing through the side of the electric control box 4 is relatively low, so the heat dissipation effect on the electric control box 4 is better. Furthermore, when the air conditioner is running at high power or the outdoor ambient temperature is high, since the airflow around the electric control box 4 will not be further heated up by the outdoor heat exchanger 2, the temperature of the airflow around the electric control box 4 is relatively low and will not exceed its own limit temperature. The electric control box 4 can dissipate heat normally, thus avoiding the shutdown of the electric control box 4 under high temperature conditions, and having greater stability and longer service life.

[0091] like Figure 6-Figure 9As shown, the side wall of the outdoor heat exchanger 2 has a connecting flange 72, and the connecting flange 72 is connected to the partition 6. The side wall of the outdoor heat exchanger 2 is connected to the partition 6 through the connecting flange 72. On the one hand, the contact area between the side wall of the outdoor heat exchanger 2 and the partition 6 is increased, so that the connection between the partition 6 and the side wall of the outdoor heat exchanger 2 is more stable, and a position that can be used for installation and connection is provided between the side wall of the outdoor heat exchanger 2 and the partition 6 extending in different directions. On the other hand, the setting of the connecting flange 72 protects the integrated structure on the side wall of the outdoor heat exchanger 2, and avoids the setting of fasteners or the welding process and other processes affecting the sealing of the integrated structure on the side wall of the outdoor heat exchanger 2.

[0092] In some embodiments, the connection flange 72 and the partition 6 are connected by fasteners. Specifically, the connection flange 72 is provided with a first connection hole 721, and the partition 6 is provided with a second connection hole 611. The partition 6 and the connection flange 72 are connected by a third fastener 50, and the third fastener 50 is passed through the first connection hole 721 and the second connection hole 611.

[0093] In some embodiments, there are multiple first connection holes 721 and second connection holes 611, respectively, and they are arranged one by one. Multiple third fasteners 50 are passed through the first connection holes 721 and the second connection holes 611 to ensure the stability of the connection between the partition 6 and the side wall of the outdoor heat exchanger 2.

[0094] In other embodiments, the connection flange 72 and the separator 6 may be connected by welding, snap-fitting, etc., which is not limited here.

[0095] like Figure 7 and Fig. 9 As shown, the partition 6 is also connected to the side wall and / or the bottom wall of the casing 1 to ensure the stability of the partition 6.

[0096] In some embodiments, the partition 6 is connected to the side wall and / or bottom wall of the casing 1 through fasteners. Specifically, a third connecting hole may be provided on the casing 1, and a fourth connecting hole may be provided on the partition 6. The casing 1 and the partition 6 are connected through a second fastener, and the second fastener passes through the third connecting hole and the fourth connecting hole.

[0097] In other embodiments, the partition 6 is connected to the side wall and / or bottom wall of the housing 1 by welding, bonding, or snapping, which is not limited here.

[0098] The air conditioner according to the embodiment of the utility model includes an air conditioner indoor unit and the above-mentioned air conditioner outdoor unit 1000. By adopting the above-mentioned air conditioner outdoor unit 1000, the air conditioner can ensure stable operation under high temperature conditions, have a longer service life, better performance, and a better user experience.

[0099] The other structures of the air conditioner are already in the prior art and are well known to those skilled in the art, so they will not be described in detail here.

[0100] An embodiment of the air conditioner outdoor unit 1000 is described below with reference to the accompanying drawings.

[0101] like Figure 1-Figure 17 As shown, the air conditioner outdoor unit 1000 includes: a casing 1, a partition 6, a mounting plate 5, an outdoor heat exchanger 2, an outdoor fan 3, an electric control box 4 and a compressor 90.

[0102] The housing 1 defines a receiving space 100 and has an air inlet 101 and an air outlet 102 . The housing 1 comprises a housing body 12 and a top cover 13 . The housing body 12 has a top opening 121 . The top cover 13 is detachably disposed on the housing body 12 for opening and closing the top opening 121 .

[0103] The outdoor heat exchanger 2 is arranged opposite to the air inlet 101, and the outdoor fan 3 is arranged at a position corresponding to the air outlet 102, which is used to drive the air to form an airflow so that the airflow flows from the air inlet 101 to the air outlet 102, that is, the airflow enters the accommodating space 100 from the air inlet 101 under the drive of the outdoor fan 3, and flows out of the accommodating space 100 from the air outlet 102. The airflow will flow through the outdoor heat exchanger 2 in the process of flowing from the air inlet 101 to the air outlet 102.

[0104] The outdoor heat exchanger 2, the partition 6 and the mounting plate 5 are placed upright in the accommodating space 100. There is a part on the outdoor heat exchanger 2 that extends toward the outdoor fan 3, and the part forms the first heat exchange part 21. The mounting plate 5 is placed upright in the accommodating space 100 and is connected to the first heat exchange part 21 and the side wall of the casing 1. The partition 6 is placed upright in the accommodating space 100 and is connected to the first heat exchange part 21 and the front wall of the casing 1. The partition, the mounting plate 5 and the first heat exchange part 21 of the outdoor heat exchanger 2 are in a "Y"-shaped structure, dividing the accommodating space 100 into three cavities. One side of the partition 6 in the thickness direction and the air outlet side of the outdoor heat exchanger 2 and the casing 1 define an air duct cavity 20 for placing the outdoor fan 3. The airflow flows from the air inlet 101 through the outdoor heat exchanger 2 into the air duct cavity 20, and flows out of the air duct cavity 20 through the air outlet 102. An installation cavity 10 for installing the electric control box 4 is defined between one side of the mounting plate 5 in the thickness direction, the air inlet side of the first heat exchange part 21, and the casing 1, and an accommodating cavity 30 for placing the compressor 90 is defined between the other side of the partition 6 in the thickness direction, the other side of the mounting plate 5 in the thickness direction, and the casing 1.

[0105] Among them, the part of the outdoor heat exchanger 2 opposite to the partition 6 is bent toward the direction close to the outdoor fan 3 to form a first heat exchange part 21, so as to change the flow direction of the airflow after passing through the first heat exchange part 21 of the outdoor heat exchanger 2, increase the angle between the partition 6 and the first heat exchange part 21, and reduce the projection area of ​​the partition 6 on the outdoor heat exchanger 2 in the gas flow direction, thereby avoiding the setting of the partition 6 affecting the airflow flow speed and improving the heat exchange effect of the outdoor heat exchanger 2.

[0106] The space between the air inlet side of the outdoor heat exchanger 2 and the side wall of the casing 1 is the upstream space of the outdoor heat exchanger 2 , and the space defines an installation cavity 10 , and the electric control box 4 is arranged in the installation cavity 10 .

[0107] That is to say, the electrical control box 4 is arranged upstream of the outdoor heat exchanger 2. On the one hand, the airflow generated by the outdoor fan 3 is utilized to avoid setting up an independent structure outside the outdoor fan 3 for the airflow driving of the electrical control box 4 during the heat dissipation process, thereby reducing production costs.

[0108] On the other hand, in the process of the airflow flowing from the air inlet 101 to the air outlet 102 driven by the outdoor fan 3, at least part of the airflow first passes through the installation cavity 10, and the airflow dissipates the heat for the electric control box 4 in the installation cavity 10, and then exchanges heat with the outdoor heat exchanger 2 through the outdoor heat exchanger 2. Since part of the airflow flowing through the installation cavity 10 is not subjected to heat exchange by the outdoor heat exchanger 2, the temperature is relatively low, that is, the temperature of the airflow passing through the side of the electric control box 4 is relatively low, so the heat dissipation effect on the electric control box 4 is better. Furthermore, when the air conditioner is running at high power or the outdoor ambient temperature is high, since the airflow around the electric control box 4 will not be further heated up by the outdoor heat exchanger 2, the temperature of the airflow around the electric control box 4 is relatively low and will not exceed its own limit temperature. The electric control box 4 can dissipate heat normally, thus avoiding the shutdown of the electric control box 4 under high temperature conditions, and having greater stability and longer service life.

[0109] The mounting plate 5 can provide an installation position for the electric control box 4. The mounting plate 5 is placed upright in the accommodation space 100, and is arranged parallel to the electric control box 4 placed upright in the accommodation space 100. The contact area between the mounting plate 5 and the electric control box 4 is larger, which is more conducive to the installation of the electric control box 4. The electric control box 4 is arranged more stably. The electric control box 4 is fixed to the side of the mounting plate 5 facing the air inlet 101 in the thickness direction to avoid the setting of the mounting plate 5 blocking the airflow to the electric control box 4.

[0110] Combination Figure 12-14 In the illustrated embodiment, the electric control box 4 and the mounting plate 5 are detachably connected. By detachably connecting the electric control box 4 and the mounting plate 5, the installation and removal of the electric control box 4 can be facilitated. When the electric control box 4 is to be inspected and repaired, the electric control box 4 can be simply removed and taken out from the accommodating space 100, so that the electric control box 4 can be conveniently inspected and repaired, thereby reducing the maintenance cost.

[0111] like Fig.14 As shown, the electric control box 4 and the mounting plate 5 can be connected by a snap-fit ​​structure and fasteners at the same time, wherein the mounting plate 5 is provided with a snap-fitting hole 52, and the electric control box 4 is provided with a snap-fitting hook 43, and the snap-fitting hook 43 is snap-fitted with the snap-fitting hole 52, thereby not only being able to conveniently realize the connection between the electric control box 4 and the mounting plate 5, but also being able to locate the position of the electric control box 4, so as to facilitate the subsequent use of fasteners to further tightly connect the electric control box 4 and the mounting plate 5, the mounting plate 5 is provided with a first fixing hole 53, and the electric control box 4 is provided with a second fixing hole 44, the mounting plate 5 and the electric control box 4 are connected by a fixing member 60, and the fixing member 60 is penetrated through the first fixing hole 53 and the second fixing hole 44, so as to fasten the electric control box 4 and the mounting plate 5 by the fixing member 60, so as to ensure the stability of the setting of the electric control box 4.

[0112] Reference Fig. 9 The mounting plate 5 and the outdoor heat exchanger 2 are arranged in the width direction of the casing 1, wherein the air inlet 101 and the air outlet 102 are respectively arranged on both sides of the casing 1 in the width direction. In some embodiments, the width direction can be the front and rear direction of the outdoor air conditioner. In order to ensure that the outdoor air conditioner has an air inlet 101 and an air outlet 102 with sufficient areas, the air outlet 102 is arranged on the front side of the casing 1, and at least a part of the air inlet 101 is arranged on the rear side of the casing 1.

[0113] The outdoor fan 3 and the outdoor heat exchanger 2 are respectively arranged on both sides of the casing 1 in the width direction, and are respectively arranged close to the air inlet 101 and the air outlet 102. In some embodiments, the outdoor fan 3 is arranged at the front side of the accommodating space 100, and is arranged close to the air outlet 102 opened on the front side of the casing 1, and the outdoor heat exchanger 2 is arranged at the rear side of the accommodating space 100, and is arranged close to the air inlet 101 opened on the rear side of the casing 1.

[0114] The mounting plate 5 and the outdoor heat exchanger 2 are arranged in the width direction of the casing 1, that is, the mounting plate 5 and the outdoor heat exchanger 2 are arranged one after the other, and the mounting plate 5 is arranged on the front side of the outdoor heat exchanger 2 so that the mounting plate 5 can be spaced apart from the air inlet part 101, so that the electric control box 4 can be arranged in the space between the air inlet part 101 and the mounting plate 5.

[0115] like Figure 6-Figure 8 As shown, a side plate 7 is provided on one side of the first heat exchange part 21 in the width direction. The side plate 7 can realize the installation of the heat exchanger and the integration of part of the transition structure of the outdoor heat exchanger 2. The side plate 7 also provides an installation position for the installation plate 5 and the partition 6. The first heat exchange part 21 is connected to the installation plate 5 and the partition 6 through the side plate 7.

[0116] The mounting plate 5 and the partition 6 are respectively connected to the two ends of the side plate 7. Since an accommodating chamber 30 for placing the compressor 90 is defined between the other side of the partition 6 in the thickness direction and the other side of the mounting plate 5 in the thickness direction and the casing 1, that is, an accommodating chamber 30 for placing the compressor 90 is defined between the side of the side plate 7 in the thickness direction away from the first heat exchange part 21 and the other side of the partition 6 in the thickness direction and the other side of the mounting plate 5 in the thickness direction and the casing 1, the adapter structure integrated on the side plate 7 can be directly connected to the compressor 90 arranged in the accommodating chamber 30 without crossing the partition or the mounting plate 5, and the pipeline will not invade the air duct cavity 20 under the protection of the partition, thereby avoiding the pipeline from being damaged in the air duct cavity 20.

[0117] Reference Figure 8 A first mounting flange 71 is provided on one side of the side plate 7 in the width direction, and the first mounting flange 71 is connected to one side of the mounting plate 5 in the width direction. The side plate 7 is connected to the mounting plate 5 through the first mounting flange 71. On the one hand, the contact area between the side plate 7 and the mounting plate 5 is increased, so that the connection between the mounting plate 5 and the side plate 7 is more stable, and a position that can be used for installation and connection is provided between the side plate 7 and the mounting plate 5 extending in different directions. On the other hand, the setting of the first mounting flange 71 protects the integrated structure on the side plate 7, and avoids the setting of fasteners or the welding process affecting the sealing of the integrated structure on the side plate 7.

[0118] The first mounting flange 71 is connected to the mounting plate 5 by fasteners. Figure 8 and Fig.13 The first mounting flange 71 is provided with a first mounting hole 711 , and the mounting plate 5 is provided with a first matching hole 51 . The first mounting flange 71 and the mounting plate 5 are connected through a first fastener 40 , and the first fastener 40 is passed through the first mounting hole 711 and the first matching hole 51 .

[0119] There are multiple first mounting holes 711 and multiple first matching holes 51 , respectively, and they are arranged one by one. Multiple first fasteners 40 are passed through the first mounting holes 711 and the first matching holes 51 to ensure the stability of the connection between the side plate 7 and the mounting plate 5 .

[0120] like Figure 6-Figure 9 As shown, a connecting flange 72 is provided on the other side of the side plate 7 in the width direction, and the connecting flange 72 is connected to the partition 6. The side plate 7 and the partition 6 are connected by the connecting flange 72. On the one hand, the contact area between the side plate 7 and the partition 6 is increased, so that the connection between the partition 6 and the side plate 7 is more stable, and a position that can be used for installation and connection is provided between the side plate 7 and the partition 6 extending in different directions. On the other hand, the setting of the connecting flange 72 protects the integrated structure on the side plate 7, and avoids the setting of fasteners or the welding process and other processes affecting the sealing of the integrated structure on the side plate 7.

[0121] In some embodiments, the connection flange 72 and the partition 6 are connected by fasteners, the connection flange 72 is provided with a first connection hole 721, the partition 6 is provided with a second connection hole 611, the partition 6 and the connection flange 72 are connected by a third fastener 50, and the third fastener 50 is passed through the first connection hole 721 and the second connection hole 611.

[0122] There are multiple first connection holes 721 and multiple second connection holes 611 , respectively, and they are arranged one by one. Multiple third fasteners 50 are passed through the first connection holes 721 and the second connection holes 611 to ensure the stability of the connection between the partition 6 and the side plate 7 .

[0123] Reference Figure 2 , Figure 3 , Figure 5 , Figure 7 and Fig.11 , a second mounting flange 54 is provided on the other side of the mounting plate 5 in the width direction, and the second mounting flange 54 is connected to the side wall of the housing 1. The mounting plate 5 is connected to the side wall of the housing 1 by the second mounting flange 54, which increases the contact area between the side wall of the housing 1 and the mounting plate 5, making the connection between the side wall of the housing 1 and the mounting plate 5 more stable, and providing a position for mounting and connecting between the side wall of the housing 1 and the mounting plate 5 extending in different directions.

[0124] The mounting plate 5 is connected to the side wall of the casing 1 through fasteners. Specifically, the second mounting flange 54 is provided with a second mounting hole 541, and the side wall of the casing 1 is provided with a second matching hole 1121. The second mounting flange 54 is connected to the side wall of the casing 1 through a second fastener, and the second fastener is passed through the second mounting hole 541 and the second matching hole 1121.

[0125] There are multiple second mounting holes 541 and multiple second matching holes 1121 , respectively, and they are arranged one by one. Multiple second fasteners are passed through the second mounting holes 541 and the second matching holes 1121 to ensure the stability of the connection between the mounting plate 5 and the side wall of the housing 1 .

[0126] Among them, at least one second fastener is arranged near the upper end of the second mounting flange 54, and the second fastener near the upper end of the second mounting flange 54 is also connected to the top cover 13. That is to say, through a second fastener, the mounting plate 5, the shell body 12 and the top cover 13 can be connected together at the same time. Therefore, the second fastener can not only stably connect the second mounting flange 54 to the side wall of the casing 1, but also fix the top cover 13 above the shell body 12 to avoid the top cover 13 falling off and causing danger. At the same time, it reduces the number of fasteners required for the outdoor air conditioner, reduces production costs, and improves the sealing of the cavity for installing the compressor 90 in the air-conditioning outdoor unit 1000.

[0127] like Fig.10and Fig.12 As shown, in order to ensure the stability of the structure of the compressor 90 and other structures, the compressor 90 and other structures are usually arranged at the bottom of the accommodating space 100. Therefore, the electric control box 4 is arranged close to the top wall of the casing 1, that is, the electric control box 4 is arranged above the compressor 90 and other structures. This can avoid the setting of the electric control box 4 affecting the arrangement of the compressor 90 and other structures, ensure that the internal structure of the air-conditioning outdoor unit 1000 is compact, and reduce the volume of the air-conditioning outdoor unit 1000.

[0128] like Figure 5 As shown, a reinforcing flange 55 is provided at the upper end of the mounting plate 5, and the reinforcing flange 55 can strengthen the strength of the mounting plate 5, avoid deformation of the mounting plate 5 caused by force on the upper part of the mounting plate 5, ensure the structural stability of the mounting plate 5, and further improve the stability of the setting of the electric control box 4.

[0129] Reference Figure 6 The partition 6 includes: a second partition 63, a first partition 62 and a connecting plate 61. The connecting plate 61 is connected to one side of the first partition 62 in the width direction. The connecting plate 61 can mainly realize the function of connecting the partition 6 and the side plate 7 together. The first partition 62 is connected to the side plate 7 through the connecting plate 61. The connecting flange 72 of the side plate 7 is connected to the connecting plate 61 of the partition 6. Through the cooperation of the connecting flange 72 and the connecting plate 61 of the partition 6, the contact area between the side plate 7 and the partition 6 can be increased, so that the connection between the partition 6 and the side plate 7 is more stable, and a position that can be used for installation and connection is provided between the side plate 7 and the partition 6 in different extending directions.

[0130] Among them, the first partition 62 is arranged opposite to the first heat exchange part 21. The first partition 62 can guide the airflow entering the air duct cavity 20 through the first heat exchange part 21, guide it to the outdoor fan, control the flow direction of the airflow in the air duct cavity 20, and ensure the flow rate of the airflow in the air duct cavity 20.

[0131] Furthermore, in order to avoid the partition from blocking the flow of air and affecting the heat exchange performance of the outdoor heat exchanger 2, the angle α between the first partition 62 and the first heat exchange part 21 is not less than 70°, so as to reduce the projection of the partition on the outdoor heat exchanger 2 in the air inlet direction and avoid the partition from affecting the air flow rate.

[0132] In addition, the angle α between the first partition 62 and the first heat exchange part 21 is not greater than 90°, so as to avoid the angle between the partition and the first heat exchange part 21 occupying a larger space inside the air-conditioning outdoor unit 1000 and affecting the space size of the accommodating cavity 30, thereby making the internal structure of the casing 1 more compact and helping to reduce the volume of the air-conditioning outdoor unit 1000.

[0133] The two sides of the second partition 63 in the width direction are respectively connected to the casing 1 and the other side of the first partition 62 in the width direction. The second partition 63 is mainly arranged between the compressor 90 and the outdoor fan 3 to isolate the two. The extension direction of the second partition 63 is parallel to the axial direction of the outdoor fan 3. The first partition 62 is connected to the second partition 63, and can jointly separate the accommodating space 100 into the air duct cavity 20 and the accommodating cavity 30.

[0134] Since the first heat exchange part 21 of the outdoor heat exchanger 2 is arranged behind the compressor 90, the second partition 63 is arranged between the compressor 90 and the outdoor fan 3, and the first partition 62 is connected to the end of the outdoor heat exchanger 2 and the end of the second partition 63 at the same time, the width direction of the first partition 62 connecting the second partition 63 and the end of the outdoor heat exchanger 2 is inclined relative to the width direction of the second partition 63, so that the first partition 62 can connect the second partition 63 and the outdoor heat exchanger 2 with the ends staggered.

[0135] The electric control box 4 is placed vertically in the installation cavity 10 to reduce the thickness of the installation cavity 10, that is, to reduce the distance between the first heat exchange part 21 and the housing 1, and to reduce the size of the outdoor heat exchanger 2 invading the internal space of the accommodation space 100, so as to facilitate the arrangement of the internal structure of the air-conditioning outdoor unit 1000, reduce the volume of the air-conditioning outdoor unit 1000, and realize the lightweight of the air conditioner. In addition, by placing the electric control box 4 vertically, a larger surface of the electric control box 4 can face the incoming wind direction, thereby increasing the windward area of ​​the electric control box 4 and ensuring the heat dissipation effect.

[0136] Among them, the angle between the first heat exchange part 21 and the side wall of the casing 1 can be greater than 0 degrees and less than 90 degrees, so as to ensure that the first heat exchange part 21 and the casing 1 are spaced apart, and at the same time ensure that a safety cavity can be defined between the first heat exchange part 21 and the casing 1.

[0137] The air inlet part 101 includes a first air inlet area 1111, and the first air inlet area 1111 is arranged corresponding to the first heat exchange part 21. The airflow entering the air-conditioning outdoor unit 1000 through the first air inlet area 1111 will first pass through the installation cavity 10, and perform heat exchange with the electric control box 4 arranged in the installation cavity 10, so that the electric control box 4 can be fully dissipated. Then, the airflow will flow to the first heat exchange part 21, and after passing through the first heat exchange part 21, it will flow out of the air-conditioning outdoor unit 1000 from the air outlet part 102.

[0138] The outdoor heat exchanger 2 further includes a main heat exchange unit 22 and a second heat exchange unit 23. Figure 2 , Figure 7 , Fig. 9 and Fig.15The main heat exchange part 22 is arranged opposite to the rear side wall of the casing 1, the first heat exchange part 21 is connected to one side of the width direction of the main heat exchange part 22, and the width direction of the first heat exchange part 21 is inclined relative to the width direction of the main heat exchange part 22.

[0139] Reference Fig. 9 The distance between the side of the first heat exchange part 21 away from the main heat exchange part 22 and the rear wall of the casing 1 in the front-to-back direction is L, and the size of the electric control box 4 in the front-to-back direction is L1, and L is greater than or equal to L1, so as to define a space of sufficient width between the first heat exchange part 21 and the rear wall of the casing 1 for installing the electric control box 4, so as to avoid that part of the structure of the electric control box 4 is arranged outside the gas flow range, affecting the heat dissipation effect of the electric control box 4.

[0140] The outdoor heat exchanger 2 also includes a second heat exchange part 23, which is arranged opposite to the left side wall of the casing 1. The second heat exchange part 23 is connected to the other side of the main heat exchange part 22 in the width direction so that the outdoor heat exchanger 2 has a larger heat exchange area and improves the heat exchange efficiency of the outdoor heat exchanger 2.

[0141] Combination Figure 2 , Figure 3 and Figure 7 In the illustrated embodiment, the shell body 12 includes: a first side panel 11, a second side panel 17, a front panel and a bottom panel 19, the first side panel 11 includes a first plate portion 111 and a second plate portion 112 which are arranged at an angle and adjacent to each other, the first plate portion 111 forms a part of the rear side wall of the casing 1, and the second plate portion 112 forms a left side wall or a right side wall of the casing 1.

[0142] The first plate portion 111 and the second plate portion 112 are an integrally formed structure, that is, the first side plate 11 is an integrally formed part, so as to make the appearance of the outdoor air conditioner more beautiful, reduce the setting of connecting parts, and reduce the production cost.

[0143] like Figure 2 As shown, the first air inlet area 1111 is arranged on the first plate portion 111 to prevent the arrangement of the first plate portion 111 from affecting the airflow to the first heat exchange portion 21 , thereby ensuring that there is sufficient airflow around the outdoor heat exchanger 2 for heat exchange.

[0144] Reference Fig. 9 The projection of the first heat exchange part 21 on the rear wall of the casing 1 is located inside the first plate part 111, so that the first plate part 111 can be used to protect the first heat exchange part 21 and the electric control box 4 arranged between the first heat exchange part 21 and the first plate part 111, so as to prevent the external environment from corroding and damaging the electric control box 4.

[0145] like Figure 2 and Figure 7As shown, the first air inlet area 1111 has a plurality of air inlets 14 arranged at intervals, and the plurality of air inlets 14 can stably inlet air to provide airflow to the first heat exchange part 21 for heat exchange, or perform heat exchange with the structure provided in the cavity defined between the first heat exchange part 21 and the housing 1 to achieve heat dissipation of the structure. The arrangement of the plurality of air inlets 14 is conducive to increasing the air intake flow rate of the first air inlet area 1111, ensuring that the first heat exchange part 21 has sufficient airflow for heat exchange.

[0146] Reference Figure 2 The first air inlet area 1111 is provided with a plurality of parallel and spaced air guide plates 15, each air guide plate 15 is arranged obliquely relative to the horizontal plane, and an air inlet 14 is defined between any two adjacent air guide plates 15. The air guide plates 15 can block external dust and prevent dust and foreign matter from entering the cavity defined between the first heat exchange part 21 and the housing 1 through the air inlet 14, thereby improving the service life of the structure set in the cavity defined between the first heat exchange part 21 and the housing 1. In addition, the air guide plates 15 can guide the flow direction of the airflow so that the airflow flows to the position where the airflow needs to be exchanged for heat.

[0147] In some embodiments, the air guide plate 15 is tilted downward from the inside to the outside to guide the lower airflow with a lower temperature to the accommodating space 100 and better block the entry of dust moving from top to bottom.

[0148] Reference Figure 2 The first air inlet area 1111 is provided with an air inlet grille 16, and the air inlet grille 16 defines a plurality of air inlets 14. The arrangement of the air inlet grille 16 can block external dust and prevent dust and foreign matter from entering the cavity defined between the first heat exchange portion 21 and the casing 1 through the air inlet 14, thereby increasing the service life of the structure arranged in the cavity defined between the first heat exchange portion 21 and the casing 1, and can guide the direction of airflow to ensure that the airflow flows to a position where heat exchange is required.

[0149] Reference Figure 1-Figure 3 and Figure 7 The casing 1 also includes a second side plate 17 arranged opposite to the second plate portion 112 and a back plate 18 connected to the first plate portion 111 and the second side plate 17 on both sides in the width direction, a second air inlet area 181 is formed on the back plate 18, and the main heat exchange portion 22 is arranged opposite to the back plate 18.

[0150] The air inlet part 101 also includes a third air inlet area 171, and the third air inlet area 171 is arranged on the second side plate 17. The second heat exchange part 23 is arranged opposite to the second side plate 17. The airflow can flow to the second heat exchange part 23 through the third air inlet area 171, ensuring that the outdoor heat exchanger 2 has sufficient airflow for heat exchange, thereby ensuring the heat exchange efficiency of the outdoor heat exchanger 2.

[0151] like Fig.16 As shown, the electric control box 4 includes: an electric control body 41 and a radiator 42. The electric control body 41 can control the operation of the air-conditioning outdoor unit 1000, and the radiator 42 is used to increase the heat dissipation area of ​​the electric control box 4, that is, the radiator 42 is the main part of the electric control box 4 that needs to dissipate heat.

[0152] The radiator 42 is in contact with the electric control body 41, so that the heat generated by the operation of the electrical components in the electric control body 41 can be dissipated through the radiator 42. In addition, the radiator 42 is arranged opposite to the first air inlet area 1111, so that the airflow entering the air conditioner outdoor unit 1000 from the first air inlet area 1111 will first pass through the radiator 42 and perform heat exchange with the radiator 42, which can not only ensure the flow rate of the airflow passing through the radiator 42, but also make the temperature of the airflow passing through the radiator 42 as low as possible, thereby improving the heat dissipation effect of the electric control box 4.

[0153] Reference Fig.17 The radiator 42 includes a heat sink 421 and a plurality of heat sinks 422. One side of the heat sink 421 in the thickness direction is in contact with the electric control body 41 to achieve heat transfer. The heat sink 421 can integrate the plurality of heat sinks 422 into one. Thus, the heat generated by the operation of the electrical components in the electric control body 41 can be transferred to the heat sink 422 through the heat sink 421, and heat exchange is performed with the passing airflow at the heat sink 422 to achieve sufficient heat dissipation of the electric control box 4.

[0154] like Figure 3 , Figure 4 , Fig. 9 and Fig.12 As shown, the heat sink 421 is placed upright in the installation cavity 10, and a plurality of heat sinks 422 are connected to the other side of the heat sink 421 in the thickness direction and are arranged at intervals in the vertical direction. A heat dissipation channel 423 is defined between two adjacent heat sinks 422. The extension direction of the heat dissipation channel 423 is horizontal, and the flow direction of the airflow in the installation cavity 10 is also horizontal, so that the airflow can flow evenly through each heat dissipation channel 423, ensuring that each heat sink 422 can fully contact the airflow and perform heat exchange, thereby ensuring the heat dissipation effect of the electric control box 4. In addition, the setting of the heat sink 422 will not block the flow of the airflow in the horizontal direction, avoiding the setting of the electric control box 4 affecting the flow speed and flow rate of the airflow passing through the outdoor heat exchanger 2, thereby ensuring the heat exchange effect of the outdoor heat exchanger 2.

[0155] Reference Fig.16The electric control body 41 includes: a shell 411 and an electric control board 412. The electric control board 412 is vertically arranged in the shell 411 to reduce the overall volume of the electric control box 4. The shell 411 protects the electric control board 412 on the outside of the electric control board 412. At least a part of the radiator 42 is arranged in the shell 411 to facilitate the connection between the radiator 42 and the electric control board 412 to achieve better heat dissipation. At least a part of the radiator 42 is arranged outside the shell 411 and is located on the side of the electric control board 412 facing the first air inlet area 1111 to ensure that the radiator 42 can directly contact the airflow to avoid the airflow being blocked by the shell 411, and to ensure that the radiator 42 can contact the airflow that first enters the installation cavity 10 to ensure the heat dissipation effect of the radiator 42.

[0156] like Fig.16 As shown, the housing 411 includes: a mounting housing 4111 and a cover 4112. The mounting housing 4111 and the cover 4112 are separately arranged to facilitate the installation and removal of the electric control board 412, and to facilitate the molding of the housing 411, thereby reducing the production and maintenance costs of the housing 411. The mounting housing 4111 is placed upright in the mounting cavity 10, so that the electric control box 4 can be placed upright in the mounting cavity 10 as a whole. The cover 4112 is connected to the side of the mounting housing 4111 facing the first air inlet area 1111 and an opening is provided on the cover 4112. The radiator 42 can extend to the outside of the housing 411 through the opening provided on the cover 4112, and extend in a direction close to the first air inlet area 1111, so that the radiator 42 can contact the intake air flow without obstruction, so that the radiator 42 can better receive the intake air flow.

[0157] The electric control board 412 is disposed between the mounting shell 4111 and the cover body 4112 , so as to be protected by the cover body 4112 and the mounting shell 4111 , thereby preventing the structure on the electric control board 412 from being damaged by the external environment.

[0158] Combination Figure 4 , Fig.16 and Fig.17 In the illustrated embodiment, the radiator 42 has a limiting step 424, and at least a portion of the edge of the opening is stopped at the limiting step 424 to limit at least a portion of the radiator 42 in the shell 411, so that the radiator 42 is arranged more stably, and at the same time, unnecessary fasteners used for connecting and limiting the radiator 42 can be reduced. In other words, the overall installation of the electrical control box 4 only requires connecting the cover body 4112 and the mounting shell 4111 together, and the production and installation process is convenient.
