Description

[0002] In the prior art, an outdoor unit of an air conditioner includes a front panel, side panels, a heat exchanger, a partition, an outdoor fan, and a compressor. The front panel, one side panel, the heat exchanger, and the partition define a fan chamber, and the front panel, the partition, and the other side panel define a compressor chamber. The outdoor fan is disposed in the fan chamber and drives air flow to enter the fan chamber from the outside of the fan chamber through the heat exchanger. The compressor is disposed in the compressor chamber, and an electric control box is horizontally disposed above the partition, with both sides located in the fan chamber and the compressor chamber respectively. Among them, the heat dissipation part of the electric control box is located in the fan chamber to utilize the air flow generated by the drive of the outdoor fan for heat dissipation. Since the air flow passes through the heat exchanger for heat exchange and has a high temperature, the heat dissipation effect on the electric control box is poor.

[0071] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0072] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "vertical", "width", "thickness", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as limiting the present invention.

[0073] In addition, the terms "first" and "second" are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0074] In the present invention, unless otherwise clearly defined and limited, the terms "mounted", "connected", "connected", "fixed", etc. should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection, an electrical connection or can communicate with each other; it may be directly connected, or indirectly connected through an intermediate medium, and may be the internal communication of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0075] In the present invention, unless otherwise clearly specified or limited, the first feature being "on" or "under" the second feature may include direct contact between the first and second features, or may include the first and second features not being in direct contact but being in contact through additional features therebetween. Moreover, the first feature being "above", "over" and "on top of" the second feature includes the first feature being directly above and obliquely above the second feature, or merely indicating that the horizontal height of the first feature is higher than that of the second feature.

[0076] In the prior art, an outdoor unit of an air conditioner includes a panel, side plates, a heat exchanger, a partition, an outdoor fan and a compressor. The panel, one side plate, the heat exchanger and the partition define a fan chamber, the panel, the partition and the other side plate define a compressor chamber. The outdoor fan is disposed in the fan chamber and drives air flow to enter the fan chamber from the outside of the fan chamber through the heat exchanger. The compressor is disposed in the compressor chamber. The electric control box is horizontally disposed above the partition, with both sides located in the fan chamber and the compressor chamber respectively. Among them, the heat dissipation part of the electric control box is located in the fan chamber to dissipate heat therefrom by using the air flow generated by the driving of the outdoor fan. Since the air flow passes through the heat exchange of the heat exchanger and has a high temperature, the heat dissipation effect on the electric control box is poor. In the case where the air flow temperature is high, it will also cause the electric control box to fail to dissipate heat and shut down.

[0077] Therefore, in an embodiment of the present invention, an outdoor unit 1000 of an air conditioner is designed in which an electric control box 4 is vertically placed in an installation cavity 10 upstream of the heat exchanger. The air flow is driven by the outdoor fan 3 to flow into the accommodation space 100 from the outside of the outdoor air conditioner, passes through the installation cavity 10, dissipates heat from the electric control box 4, and then exchanges heat with the heat exchanger. The air flow temperature around the electric control box 4 is relatively low, and the heat dissipation effect on the electric control box 4 is good. Moreover, in the case where the air conditioner operates at a high power or in a high ambient temperature environment, the air flow temperature around the electric control box 4 will not exceed its own limit temperature, and the electric control box 4 can dissipate heat normally, avoiding the shutdown of the electric control box 4 in a high temperature state.

[0078] The following refers to Figures 1 - 17 Describe the outdoor unit 1000 of an air conditioner according to an embodiment of the present invention.

[0079] As Figures 1 - 17 shown, the outdoor unit 1000 of an air conditioner includes: a housing 1, an outdoor heat exchanger 2, an outdoor fan 3 and an electric control box 4.

[0080] The housing 1 defines an accommodation space 100 and has an air inlet part 101 and an air outlet part 102. The outdoor fan 3 is arranged in the accommodation space 100 and is used to drive air to form an air flow, so that the air flow flows from the air inlet part 101 to the air outlet part 102. That is, the air flow enters the accommodation space 100 from the air inlet part 101 under the drive of the outdoor fan 3 and flows out of the accommodation space 100 from the air outlet part 102. The outdoor heat exchanger 2 is arranged in the accommodation space 100. The air flow will flow through the outdoor heat exchanger 2 during the process of flowing from the air inlet part 101 to the air outlet part 102. The side of the outdoor heat exchanger 2 facing the air inlet part 101 is the air inlet side.

[0081] Among them, the upstream space of the outdoor heat exchanger 2 is between the air inlet side of the outdoor heat exchanger 2 and the side wall of the housing 1. This space defines an installation cavity 10, and the electric control box 4 is arranged in the installation cavity 10.

[0082] That is to say, the electric control box 4 is arranged upstream of the outdoor heat exchanger 2. On the one hand, the air flow driven by the outdoor fan 3 is utilized to avoid arranging an independent structure outside the outdoor fan 3 for driving the air flow during the heat dissipation process of the electric control box 4, thereby reducing the production cost.

[0083] On the other hand, during the process that the air flow flows from the air inlet part 101 to the air outlet part 102 under the drive of the outdoor fan 3, at least part of the air flow first passes through the installation cavity 10. After the air flow dissipates heat from the electric control box 4 in the installation cavity 10, it then exchanges heat with the outdoor heat exchanger 2 through the outdoor heat exchanger 2. Since part of the air flow flowing through the installation cavity 10 has not been heat-exchanged by the outdoor heat exchanger 2 and has a lower temperature, that is, the air flow passing through the periphery of the electric control box 4 has a lower temperature, so the heat dissipation effect on the electric control box 4 is better. Further, when the air conditioner operates at high power or in the case of a relatively high outdoor ambient temperature, since the air flow on the periphery of the electric control box 4 will not be further heated under the action of the outdoor heat exchanger 2, the temperature of the air flow on the periphery of the electric control box 4 is relatively low and does not exceed its own limit temperature. The electric control box 4 can dissipate heat normally, avoiding the shutdown of the electric control box 4 in a high-temperature state, and has better stability and a longer service life.

[0084] Further, the electric control box 4 is placed upright in the installation cavity 10 upstream of the heat exchanger. In the prior art, the outdoor heat exchanger 2 is arranged closely to the air inlet part 101 of the housing 1, that is, the air flow passes through the outdoor heat exchanger 2 immediately after entering the accommodation space 100. In order to create a space in the housing 1 and upstream of the outdoor heat exchanger 2 to accommodate the electric control box 4, at least a part of the outdoor heat exchanger 2 needs to be spaced from the side wall of the housing 1. This part of the outdoor heat exchanger 2 will occupy the internal space of the accommodation space 100, resulting in difficulties in the internal structure layout of the outdoor air conditioner, affecting the volume of the outdoor air conditioner, and affecting the lightweight of the air conditioner.

[0085] Therefore, by vertically arranging the electronic control box 4, the thickness of the installation cavity 10 for installing the electronic control box 4 can be reduced, that is, the distance between part of the outdoor heat exchanger 2 and the housing 1 is reduced, the size of the space occupied by the outdoor heat exchanger 2 inwardly invading the internal space of the accommodation space 100 is reduced, facilitating the arrangement of the internal structure of the air conditioner outdoor unit 1000, reducing the volume of the air conditioner outdoor unit 1000, and realizing the lightweight of the air conditioner. Moreover, by vertically arranging the electronic control box 4, a larger surface of the electronic control box 4 can face the oncoming wind direction, thereby increasing the windward area of the electronic control box 4 and ensuring the heat dissipation effect.

[0086] For the air conditioner outdoor unit 1000 according to the embodiment of the present invention, the internal structure of the air conditioner outdoor unit 1000 is more reasonably arranged, the heat dissipation effect of the electronic control box 4 is better, and it has better stability and a longer service life.

[0087] As Figure 9 shown, the air inlet part 101 includes a first air inlet area 1111. The air flow entering the air conditioner outdoor unit 1000 through the first air inlet area 1111 will first pass through the installation cavity 10, perform heat exchange with the electronic control box 4 arranged in the installation cavity 10 to fully dissipate the heat of the electronic control box 4, then flow towards the outdoor heat exchanger 2, and flow out of the air conditioner outdoor unit 1000 from the air outlet part 102 after passing through the outdoor heat exchanger 2.

[0088] Among them, as Figure 16 shown, the electronic control box 4 includes: an electronic control main body 41 and a radiator 42. The electronic control main body 41 can control the operation of the air conditioner outdoor unit 1000, and the radiator 42 is used to increase the heat dissipation area of the electronic control box 4, that is, the radiator 42 is the main part that needs to dissipate heat in the electronic control box 4.

[0089] Among them, the radiator 42 is in contact with the electronic control main body 41 so that the heat generated by the operation of the electrical components in the electronic control main body 41 can be dissipated through the radiator 42. Moreover, the radiator 42 is arranged opposite to the first air inlet area 1111. Thus, the air flow 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 air flow passing through the radiator 42, but also make the temperature of the air flow passing through the radiator 42 as low as possible, improving the heat dissipation effect of the electronic control box 4.

[0090] Referring to Figure 17 , the radiator 42 includes a heat dissipation plate 421 and a plurality of heat dissipation fins 422. One side in the thickness direction of the heat dissipation plate 421 is in contact with the electronic control main body 41 to achieve heat transfer. The heat dissipation plate 421 can integrate the plurality of heat dissipation fins 422. Thus, the heat generated by the operation of the electrical components in the electronic control main body 41 can be transferred to the heat dissipation fins 422 through the heat dissipation plate 421 and perform heat exchange with the passing air flow at the heat dissipation fins 422 to achieve full heat dissipation of the electronic control box 4.

[0091] As Figure 3 , Figure 4 , Figure 9 and Figure 12 shown, the heat dissipation plate 421 is placed vertically in the installation cavity 10. A plurality of heat dissipation fins 422 are connected to the other side of the heat dissipation plate 421 in the thickness direction and are arranged at intervals in the up and down direction. A heat dissipation channel 423 is defined between two adjacent heat dissipation fins 422. The extending direction of the heat dissipation channel 423 is the horizontal direction, and the flowing direction of the air flow in the installation cavity 10 is also the horizontal direction. Thus, the air flow can evenly flow through each heat dissipation channel 423, ensuring that each heat dissipation fin 422 can fully contact the air flow and perform heat exchange, ensuring the heat dissipation effect of the electronic control box 4. And the setting of the heat dissipation fins 422 does not block the air flow in the horizontal direction, avoiding the influence of the setting of the electronic control box 4 on the flowing speed and flow rate of the air flow passing through the outdoor heat exchanger 2, ensuring the heat exchange effect of the outdoor heat exchanger 2.

[0092] Referring to Figure 16 , the electronic control main body 41 includes: a housing 411 and an electronic control board 412. The electronic control board 412 is placed vertically in the housing 411 to reduce the overall volume of the electronic control box 4. The housing 411 protects the electronic control board 412 on the outside of the electronic control board 412. At least a part of the radiator 42 is arranged in the housing 411 to facilitate the connection between the radiator 42 and the electronic control board 412 to achieve better heat dissipation. At least a part of the radiator 42 is arranged outside the housing 411 and is located on the side of the electronic control board 412 facing the first air inlet area 1111 to ensure that the radiator 42 can directly contact the air flow, avoid the air flow being blocked by the housing 411, and ensure that the radiator 42 can contact the air flow that first enters the installation cavity 10, ensuring the heat dissipation effect of the radiator 42.

[0093] As Figure 16 shown, the housing 411 includes: an installation shell 4111 and a cover body 4112. The installation shell 4111 and the cover body 4112 are separately arranged to facilitate the installation and disassembly of the electronic control board 412 and facilitate the molding of the housing 411, reducing the production and maintenance costs of the housing 411. Among them, the installation shell 4111 is placed vertically in the installation cavity 10 so that the whole electronic control box 4 can be placed vertically in the installation cavity 10. The cover body 4112 is connected to the side of the installation shell 4111 facing the first air inlet area 1111 and an opening is provided on the cover body 4112. The radiator 42 can extend to the outside of the housing 411 through the opening provided on the cover body 4112 and extend towards the direction close to the first air inlet area 1111, so that the radiator 42 can contact the intake air flow without obstruction, enabling the radiator 42 to better receive the intake air flow.

[0094] The electronic control board 412 is disposed between the mounting case 4111 and the cover body 4112, and is protected by the cover body 4112 and the mounting case 4111 between the mounting case 4111 and the cover body 4112, so as to prevent the structure on the electronic control board 412 from being damaged by the external environment.

[0095] Combined with Figure 4 、 Figure 16 and Figure 17 As shown in the embodiments, the radiator 42 has a limiting step 424, and at least a part of the edge of the opening abuts against the limiting step 424 to limit at least a part of the radiator 42 within the housing 411, so that the radiator 42 is set more stably. At the same time, unnecessary fasteners can be reduced for the connection and limitation of the radiator 42. In other words, the overall installation of the electronic control box 4 can be realized only by connecting the cover body 4112 and the mounting case 4111 together, and the production and installation process is convenient.

[0096] In other embodiments, the radiator 42 is fixedly connected to the housing 411 or the electronic control board 412. The fixing method can be welding, bonding or fastener connection, etc., to realize the stable setting of the radiator 42. The specific connection method is not limited herein.

[0097] Referring to Figures 7 - 9 , since the installation cavity 10 is located upstream of the outdoor heat exchanger 2, at least a part of the outdoor heat exchanger 2 needs to be spaced apart from the air inlet portion 101 defined on the side wall of the machine shell 1, so that an installation cavity 10 can be defined between the outdoor heat exchanger 2 and the air inlet portion 101.

[0098] Referring to Figure 9 , a part of the outdoor heat exchanger 2 extends towards the direction close to the outdoor fan 3 to form a first heat exchange portion 21. Thus, the first heat exchange portion 21 can be spaced apart from the air inlet portion 101 defined on the side wall of the machine shell 1. An installation cavity 10 is defined between the air inlet side of the first heat exchange portion 21 and the side wall of the machine shell 1, and the installation cavity 10 can be disposed upstream of the first heat exchange portion 21.

[0099] The air flow is driven by the outdoor fan 3 to enter the air conditioner outdoor unit 1000 through the air inlet portion 101, and first passes through the installation cavity 10, exchanges heat with the electronic control box 4 in the installation cavity 10, so that the electronic control box 4 is fully cooled, then flows through the first heat exchange portion 21, exchanges heat with the first heat exchange portion 21, and then flows out of the air conditioner outdoor unit 1000 through the air outlet portion 102 under the drive of the outdoor fan 3.

[0100] Wherein, the included angle between the first heat exchange portion 21 and the side wall of the machine shell 1 can be an included angle greater than 0 degrees and less than 90 degrees, so as to ensure that the first heat exchange portion 21 is spaced apart from the machine shell 1, and at the same time ensure that a safety cavity can be defined between the first heat exchange portion 21 and the machine shell 1.

[0101] In some embodiments, the first heat exchange portion 21 is formed on one side of the outdoor heat exchanger 2 close to the compressor 90, so that the installation cavity 10 is arranged close to the compressor 90, and further the position of the electronic control box 4 is closer to the compressor 90, facilitating the structural connection between the electronic control box 4 and the compressor 90.

[0102] In other embodiments, the first heat exchange portion 21 can be formed as a recessed portion recessed towards the outdoor fan 3. The electronic control box 4 is arranged in the recessed portion, or a part of the structure of the housing 1 corresponding to the heat exchanger is recessed away from the heat exchanger, and the electronic control box 4 is arranged in the space formed by the recess of the housing 1. The installation cavity 10 can be formed in a variety of different ways. It is only necessary to arrange the position of the installation cavity 10 upstream of the outdoor heat exchanger 2 in the air flow direction, so that the electronic control box 4 can obtain better heat dissipation effect.

[0103] As Figures 7 - 9 shown, the air conditioner outdoor unit 1000 further includes: a mounting plate 5 and a partition member 6. The mounting plate 5 can provide a mounting position for the installation of the electronic control box 4. In some embodiments, the mounting plate 5 can be integrally formed with the housing 411 of the electronic control box 4, or the mounting plate 5 can be integrally formed with the mounting shell 4111 of the housing 411, or the mounting plate 5 and the housing 411 can be formed separately and then connected.

[0104] Specifically, the outdoor heat exchanger 2 is placed upright in the accommodation space 100. A part of the outdoor heat exchanger 2 extends towards the outdoor fan 3, and this part forms the first heat exchange portion 21. The mounting plate 5 is placed upright in the accommodation space 100 and is connected to the first heat exchange portion 21 and the housing 1. The partition member 6 is placed upright in the accommodation space 100 and is connected to the first heat exchange portion 21 and the housing 1. The partition board, the mounting plate 5 and the first heat exchange portion 21 of the outdoor heat exchanger 2 form a structure similar to a "Y" shape to divide the accommodation space 100 into three cavities. One side in the thickness direction of the partition member 6 defines an air duct cavity 20 for placing the outdoor fan 3 between the air outlet side of the outdoor heat exchanger 2 and the housing 1. The air flow flows from the air inlet portion 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 portion 102. One side in the thickness direction of the mounting plate 5 defines an installation cavity 10 for installing the electronic control box 4 between the air inlet side of the first heat exchange portion 21 and the housing 1. The other side in the thickness direction of the partition member 6 defines an accommodation cavity 30 for placing the compressor 90 between the other side in the thickness direction of the mounting plate 5 and the housing 1.

[0105] As Figures 6 - 8 shown, a side plate 7 is provided on one side in the width direction of the first heat exchange portion 21. The side plate 7 can realize the installation of the heat exchanger and the integration of some transfer structures of the outdoor heat exchanger 2. The side plate 7 also provides a mounting position for the mounting plate 5 and the partition member 6. The first heat exchange portion 21 is connected to the mounting plate 5 and the partition member 6 through the side plate 7.

[0106] In some embodiments, the mounting plate 5 and the partition 6 are respectively connected to the two ends of the side plate 7. Since 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, that is, an accommodating cavity 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 cavity 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 damage to the pipeline in the air duct cavity 20.

[0107] 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.

[0108] In some embodiments, the first mounting flange 71 is connected to the mounting plate 5 by fasteners. Figure 8 and Figure 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 .

[0109] In some embodiments, there are multiple first mounting holes 711 and 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 .

[0110] In other embodiments, the first mounting flange 71 and the mounting plate 5 may be connected by welding, snap-fitting, etc., which is not limited here.

[0111] like Figures 6 - 9As shown in the figure, on the other side in the width direction of the side plate 7, there is a connecting flange 72. The connecting flange 72 is connected to the partition member 6. The side plate 7 and the partition member 6 are connected through the connecting flange 72. On the one hand, the contact area between the side plate 7 and the partition member 6 is increased, making the connection between the partition member 6 and the side plate 7 more stable, and there is a position available for installation and connection between the side plates 7 and the partition member 6 with different extending directions. On the other hand, the setting of the connecting flange 72 protects the structure integrated on the side plate 7, avoiding the influence of the setting of fasteners or the welding process, etc. on the sealing performance of the structure integrated on the side plate 7.

[0112] In some embodiments, the connection between the connecting flange 72 and the partition member 6 is achieved through fasteners. Specifically, the connecting flange 72 is provided with a first connection hole 721, the partition member 6 is provided with a second connection hole 611, and the partition member 6 and the connecting flange 72 are connected by a third fastener 50, and the third fastener 50 passes through the first connection hole 721 and the second connection hole 611.

[0113] In some embodiments, the first connection hole 721 and the second connection hole 611 each have a plurality of them, and they are arranged in one-to-one correspondence. A plurality of third fasteners 50 pass through the first connection hole 721 and the second connection hole 611 to ensure the stability of the connection between the partition member 6 and the side plate 7.

[0114] In other embodiments, the connection between the connecting flange 72 and the partition member 6 can be achieved through welding connection, snap connection and other methods, which are not limited herein.

[0115] Refer to Figure 6 , the partition member 6 includes: a first partition plate 62 and a connecting plate 61. The connecting plate 61 is connected to one side in the width direction of the first partition plate 62. The first partition plate 62 and the connecting plate 61 separate the two cavities between the installation cavity 10 and the air duct cavity 20. Among them, the first partition plate 62 is mainly arranged between the compressor 90 and the outdoor fan 3 to separate the two, avoiding the interference between the structures in the two cavities. The connecting plate 61 mainly functions to connect the partition member 6 and the side plate 7 together. The first partition plate 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 member 6. Through the cooperation of the connecting flange 72 and the connecting plate 61 of the partition member 6, the contact area between the side plate 7 and the partition member 6 can be increased, making the connection between the partition member 6 and the side plate 7 more stable, and there is a position available for installation and connection between the side plates 7 and the partition member 6 with different extending directions.

[0116] Among them, the first partition plate 62 is arranged opposite to the first heat exchange part 21. The first partition plate 62 can guide the air flow entering the air duct cavity 20 through the first heat exchange part 21, direct it to the outdoor fan, control the flow direction of the air flow in the air duct cavity 20, and ensure the flow rate of the air flow in the air duct cavity 20.

[0117] Further, in order to prevent 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 velocity.

[0118] Moreover, the angle α between the first partition 62 and the first heat exchange part 21 is not greater than 90°, so as to prevent the angular position between the partition and the first heat exchange part 21 from occupying a large space inside the air conditioner outdoor unit 1000, affecting the size of the accommodation cavity 30, making the internal structure of the housing 1 more compact, and being beneficial to reducing the volume of the air conditioner outdoor unit 1000.

[0119] As Figure 6 shown, the separator 6 further includes: a second partition 63, both sides in the width direction of the second partition 63 are respectively connected to the housing 1 and the other side in the width direction of the first partition 62. The second partition 63 is mainly disposed between the compressor 90 and the outdoor fan 3 to isolate the two. In some embodiments, the extending 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 divide the accommodation space 100 into an air duct cavity 20 and an accommodation cavity 30.

[0120] Since part of the structure of the outdoor heat exchanger 2 is disposed behind the compressor 90, the second partition 63 is disposed between the compressor 90 and the outdoor fan 3, and the first partition 62 is simultaneously connected to the end of the outdoor heat exchanger 2 and the end of the second partition 63. Therefore, the width direction of the first partition 62 connecting the end of the second partition 63 and the end of the outdoor heat exchanger 2 is inclined with respect 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 staggered ends.

[0121] Combined with Figure 2 、 Figure 3 and Figure 7 shown in the embodiments, the housing 1 includes: a first side plate 11, the first side plate 11 includes a first plate portion 111 and a second plate portion 112 that 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 housing 1, and the second plate portion 112 forms the left side wall or the right side wall of the housing 1.

[0122] In some embodiments, the first plate portion 111 and the second plate portion 112 can be 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.

[0123] Alternatively, in some other embodiments, the first plate portion 111 and the second plate portion 112 can be formed and connected separately for easy processing and forming, which is not limited herein.

[0124] Furthermore, the first plate portion 111 is disposed at the rear side of the installation cavity 10. The first air inlet area 1111 is provided on the first plate portion 111. The projection of the first heat exchange portion 21 on the rear side wall of the housing 1 is located within the first plate portion 111, so that the air flow can enter the accommodation space 100 from the first air inlet area 1111 under the drive of the outdoor fan 3, and the air flow entering the accommodation space 100 from the first air inlet area 1111 first passes through the installation cavity 10, exchanges heat with the electric control box 4 in the installation cavity 10, and then exchanges heat through the first heat exchange portion 21.

[0125] In some embodiments, an open opening is provided on the housing 1 corresponding to the rest of the outdoor heat exchanger 2. The air flow can directly enter the accommodation space 100 through the open opening, and passes through and exchanges heat with the outdoor heat exchanger 2, ensuring the heat exchange effect.

[0126] The air conditioner according to the embodiment of the present invention 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, has a longer service life, better performance, and a better user experience.

[0127] For other structures of the air conditioner, they are all prior art and are well known to those skilled in the art. Therefore, other structures of the air conditioner will not be described in detail here.

[0128] Next, an embodiment of the air conditioner outdoor unit 1000 will be described with reference to the accompanying drawings.

[0129] As Figures 1 - 17 shown, the air conditioner outdoor unit 1000 includes: a housing 1, a partition member 6, a mounting plate 5, an outdoor heat exchanger 2, an outdoor fan 3, an electric control box 4, and a compressor 90.

[0130] The housing 1 defines an accommodation space 100 and has an air inlet portion 101 and an air outlet portion 102. The housing 1 includes: 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.

[0131] The outdoor heat exchanger 2 is disposed opposite to the air inlet portion 101. The outdoor fan 3 is disposed corresponding to the air outlet portion 102 and is used to drive the air to form an air flow, so that the air flow flows from the air inlet portion 101 to the air outlet portion 102, that is, the air flow enters the accommodation space 100 from the air inlet portion 101 under the drive of the outdoor fan 3 and flows out of the accommodation space 100 from the air outlet portion 102. The air flow will flow through the outdoor heat exchanger 2 during the process of flowing from the air inlet portion 101 to the air outlet portion 102.

[0132] The outdoor heat exchanger 2, the partition member 6, and the mounting plate 5 are placed vertically in the accommodation space 100. A part of the outdoor heat exchanger 2 extends towards the outdoor fan 3, and this part forms the first heat exchange part 21. The mounting plate 5 is placed vertically in the accommodation space 100 and is connected to the first heat exchange part 21 and the side wall of the housing 1. The partition member 6 is placed vertically in the accommodation space 100 and is connected to the first heat exchange part 21 and the front wall of the housing 1. The partition plate, the mounting plate 5, and the first heat exchange part 21 of the outdoor heat exchanger 2 form a structure similar to a "Y" shape, dividing the accommodation space 100 into three cavities. One side in the thickness direction of the partition member 6 defines an air duct cavity 20 for placing the outdoor fan 3 between the air outlet side of the outdoor heat exchanger 2 and the housing 1. The air flow flows from the air inlet part 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 part 102. One side in the thickness direction of the mounting plate 5 defines a mounting cavity 10 for installing the electric control box 4 between the air inlet side of the first heat exchange part 21 and the housing 1. The other side in the thickness direction of the partition member 6 defines an accommodation cavity 30 for placing the compressor 90 between the other side in the thickness direction of the mounting plate 5 and the housing 1.

[0133] Wherein, the part of the outdoor heat exchanger 2 opposite to the partition member 6 is bent towards the outdoor fan 3 to form the first heat exchange part 21, so as to change the flow direction of the air flow after passing through the first heat exchange part 21 of the outdoor heat exchanger 2, increase the included angle between the partition member 6 and the first heat exchange part 21, reduce the projected area of the partition member 6 on the outdoor heat exchanger 2 in the gas flow direction, avoid the influence of the setting of the partition member 6 on the air flow velocity, and improve the heat exchange effect of the outdoor heat exchanger 2.

[0134] Wherein, the upstream space of the outdoor heat exchanger 2 is between the air inlet side of the outdoor heat exchanger 2 and the side wall of the housing 1, and this space defines the mounting cavity 10, and the electric control box 4 is arranged in the mounting cavity 10.

[0135] That is to say, the electric control box 4 is arranged upstream of the outdoor heat exchanger 2. On the one hand, the air flow driven by the outdoor fan 3 is utilized to avoid arranging an independent structure outside the outdoor fan 3 for driving the air flow during the heat dissipation process of the electric control box 4, thereby reducing the production cost.

[0136] On the other hand, during the process that the air flow flows from the air inlet part 101 to the air outlet part 102 driven by the outdoor fan 3, at least part of the air flow first passes through the installation cavity 10. After the air flow dissipates heat from the electric control box 4 in the installation cavity 10, it exchanges heat with the outdoor heat exchanger 2 through the outdoor heat exchanger 2. Since part of the air flow flowing through the installation cavity 10 does not exchange heat through the outdoor heat exchanger 2 and has a lower temperature, that is, the air flow temperature around the electric control box 4 is lower, the heat dissipation effect on the electric control box 4 is better. Further, when the air conditioner operates at high power or in the case of a relatively high outdoor ambient temperature, since the air flow around the electric control box 4 will not be further heated under the action of the outdoor heat exchanger 2, the air flow temperature 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, avoiding the shutdown of the electric control box 4 in a high-temperature state, having better stability and a longer service life.

[0137] Among them, the mounting plate 5 can provide a mounting position for the installation of the electric control box 4. The mounting plate 5 is placed vertically in the accommodation space 100 and is arranged in parallel with the electric control box 4 placed vertically 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 set more stably. The electric control box 4 is fixed on the side of the mounting plate 5 facing the air inlet part 101 in the thickness direction to prevent the arrangement of the mounting plate 5 from blocking the air flow from flowing to the electric control box 4.

[0138] Combined with Figures 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, it is convenient to install and disassemble the electric control box 4. When overhauling the electric control box 4, only the electric control box 4 needs to be disassembled and taken out from the accommodation space 100, and then the electric control box 4 can be conveniently overhauled, reducing the maintenance cost.

[0139] As Figure 14 As shown, the electric control box 4 and the mounting plate 5 can be connected through a clamping structure and fasteners at the same time. Among them, the mounting plate 5 is provided with a clamping hole 52, and the electric control box 4 is provided with a clamping hook 43. The clamping hook 43 is in clamping fit with the clamping hole 52. Thus, not only can the connection between the electric control box 4 and the mounting plate 5 be conveniently realized, but also the position of the electric control box 4 can be positioned, which is convenient for further tightly connecting the electric control box 4 and the mounting plate 5 with fasteners later. 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. The fixing member 60 passes through the first fixing hole 53 and the second fixing hole 44 to tightly connect the electric control box 4 and the mounting plate 5 through the fixing member 60, ensuring the stability of the setting of the electric control box 4.

[0140] Referring to Figure 9The 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.

[0141] 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.

[0142] 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.

[0143] like Figures 6 - 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.

[0144] 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.

[0145] Reference Figure 8, on one side in the width direction of the side plate 7, there is a first mounting flange 71. The first mounting flange 71 is connected to one side in the width direction of the mounting plate 5. The side plate 7 is connected to the mounting plate 5 through the first mounting flange 71. On the one hand, it increases the contact area between the side plate 7 and the mounting plate 5, making the connection between the mounting plate 5 and the side plate 7 more stable, and enabling a position for mounting and connection between the side plate 7 and the mounting plate 5 with different extension directions. On the other hand, the setting of the first mounting flange 71 protects the structure integrated on the side plate 7, avoiding the influence of the setting of fasteners or the welding process on the sealing performance of the structure integrated on the side plate 7.

[0146] The connection between the first mounting flange 71 and the mounting plate 5 is achieved through fasteners. Specifically, referring to Figure 8 and Figure 13 , the first mounting flange 71 is provided with a first mounting hole 711, the mounting plate 5 is provided with a first mating hole 51, and the first mounting flange 71 and the mounting plate 5 are connected by a first fastener 40, and the first fastener 40 passes through the first mounting hole 711 and the first mating hole 51.

[0147] Both the first mounting hole 711 and the first mating hole 51 have multiple ones, and they are arranged in one-to-one correspondence. Multiple first fasteners 40 pass through the first mounting hole 711 and the first mating hole 51 to ensure the stability of the connection between the side plate 7 and the mounting plate 5.

[0148] As Figures 6 - 9 shown, on the other side in the width direction of the side plate 7, there is a connecting flange 72. The connecting flange 72 is connected to the partition member 6. The side plate 7 is connected to the partition member 6 through the connecting flange 72. On the one hand, it increases the contact area between the side plate 7 and the partition member 6, making the connection between the partition member 6 and the side plate 7 more stable, and enabling a position for mounting and connection between the side plate 7 and the partition member 6 with different extension directions. On the other hand, the setting of the connecting flange 72 protects the structure integrated on the side plate 7, avoiding the influence of the setting of fasteners or the welding process on the sealing performance of the structure integrated on the side plate 7.

[0149] In some embodiments, the connection between the connecting flange 72 and the partition member 6 is achieved through fasteners. The connecting flange 72 is provided with a first connection hole 721, the partition member 6 is provided with a second connection hole 611, and the partition member 6 and the connecting flange 72 are connected by a third fastener 50, and the third fastener 50 passes through the first connection hole 721 and the second connection hole 611.

[0150] Both the first connection hole 721 and the second connection hole 611 have multiple ones, and they are arranged in one-to-one correspondence. Multiple third fasteners 50 pass through the first connection hole 721 and the second connection hole 611 to ensure the stability of the connection between the partition member 6 and the side plate 7.

[0151] Referring to Figure 2 、 Figure 3 、Figure 5 , Figure 7 and Figure 11 , on the other side in the width direction of the mounting plate 5, there is a second mounting flange 54, and the second mounting flange 54 is connected to the side wall of the housing 1. By connecting the mounting plate 5 to the side wall of the housing 1 through the second mounting flange 54, the contact area between the side wall of the housing 1 and the mounting plate 5 is increased, making the connection between the side wall of the housing 1 and the mounting plate 5 more stable, and enabling there to be positions for mounting and connection between the side walls of the housing 1 with different extending directions and the mounting plate 5.

[0152] The connection between the mounting plate 5 and the side wall of the housing 1 is achieved through fasteners. Specifically, the second mounting flange 54 is provided with a second mounting hole 541, and the side wall of the housing 1 is provided with a second mating hole 1121. The second mounting flange 54 and the side wall of the housing 1 are connected by a second fastener, and the second fastener passes through the second mounting hole 541 and the second mating hole 1121.

[0153] There are multiple second mounting holes 541 and second mating holes 1121 respectively, and they are arranged in one-to-one correspondence. Multiple second fasteners pass through the second mounting holes 541 and the second mating holes 1121 to ensure the stability of the connection between the mounting plate 5 and the side wall of the housing 1.

[0154] Among them, at least one second fastener is arranged near the upper end of the second mounting flange 54. 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 one second fastener, the mounting plate 5, the housing body 12, and the top cover 13 can be connected together at the same time. Thus, the second fastener can not only stably connect the second mounting flange 54 to the side wall of the housing 1, but also fix the top cover 13 above the housing body 12, avoiding the danger caused by the top cover 13 falling off, reducing the number of fasteners required for the outdoor air conditioner, lowering the production cost, and improving the sealing performance of the cavity for installing the compressor 90 in the outdoor air conditioner 1000.

[0155] As Figure 10 and Figure 12 shown, in order to ensure the stability of the arrangement of structures such as the compressor 90, usually the structures such as the compressor 90 are arranged at the bottom of the accommodation space 100. Therefore, setting the electronic control box 4 near the top wall of the housing 1, that is, setting the electronic control box 4 above the structures such as the compressor 90, can avoid the setting of the electronic control box 4 affecting the arrangement of the structures such as the compressor 90, ensure the compactness of the internal structure of the outdoor air conditioner 1000, and reduce the volume of the outdoor air conditioner 1000.

[0156] As Figure 5As shown, a reinforcing flange 55 is provided at the upper end of the mounting plate 5. The reinforcing flange 55 can strengthen the strength of the mounting plate 5, prevent the deformation of the mounting plate 5 caused by the force on the upper part of the mounting plate 5, ensure the structural stability of the mounting plate 5, and thus improve the stability of the installation of the electric control box 4.

[0157] Referring to Figure 6 , the partition member 6 includes: a second partition plate 63, a first partition plate 62 and a connecting plate 61. The connecting plate 61 is connected to one side of the first partition plate 62 in the width direction. The connecting plate 61 can mainly connect the partition member 6 to the side plate 7. The first partition plate 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 member 6. Through the cooperation of the connecting flange 72 and the connecting plate 61 of the partition member 6, the contact area between the side plate 7 and the partition member 6 can be increased, making the connection between the partition member 6 and the side plate 7 more stable, and providing a position for installation and connection between the side plates 7 with different extension directions and the partition member 6.

[0158] Among them, the first partition plate 62 is disposed opposite to the first heat exchange portion 21. The first partition plate 62 can guide the air flow entering the air duct cavity 20 through the first heat exchange portion 21 to the outdoor fan, control the flow direction of the air flow in the air duct cavity 20, and ensure the flow rate of the air flow in the air duct cavity 20.

[0159] Furthermore, in order to prevent the partition plate from blocking the air flow and affecting the heat exchange performance of the outdoor heat exchanger 2, the included angle α between the first partition plate 62 and the first heat exchange portion 21 is not less than 70°, so as to reduce the projection of the partition plate on the outdoor heat exchanger 2 in the air inlet direction and avoid the partition plate from affecting the air flow velocity.

[0160] And, the included angle α between the first partition plate 62 and the first heat exchange portion 21 is not greater than 90°, so as to avoid the included angle position between the partition plate and the first heat exchange portion 21 occupying a large space inside the air conditioner outdoor unit 1000 and affecting the size of the accommodation cavity 30, making the internal structure of the housing 1 more compact and conducive to reducing the volume of the air conditioner outdoor unit 1000.

[0161] Both sides of the second partition plate 63 in the width direction are respectively connected to the housing 1 and the other side of the first partition plate 62 in the width direction. The second partition plate 63 is mainly disposed between the compressor 90 and the outdoor fan 3 to isolate the two. The extension direction of the second partition plate 63 is parallel to the axis direction of the outdoor fan 3. The first partition plate 62 and the second partition plate 63 are connected and can jointly divide the accommodation space 100 into an air duct cavity 20 and an accommodation cavity 30.

[0162] 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.

[0163] 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.

[0164] 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.

[0165] 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.

[0166] The outdoor heat exchanger 2 further includes a main heat exchange unit 22 and a second heat exchange unit 23. Figure 2 , Figure 7 , Figure 9 and Figure 15 The 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.

[0167] Reference Figure 9, on one side of the first heat exchange part 21 far from the main heat exchange part 22, the distance in the front - rear direction from the rear side wall of the housing 1 is L, the size of the electric control box 4 in the front - rear direction is L1, and L is greater than or equal to L1, so as to define a space with sufficient width between the first heat exchange part 21 and the rear side wall of the housing 1 for installing the electric control box 4, avoiding part of the structure of the electric control box 4 being arranged outside the gas flow range and affecting the heat dissipation effect of the electric control box 4.

[0168] The outdoor heat exchanger 2 further includes a second heat exchange part 23. The second heat exchange part 23 is arranged opposite to the left side wall of the housing 1, and the second heat exchange part 23 is connected to the other side in the width direction of the main heat exchange part 22, 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.

[0169] Combined Figure 2 、 Figure 3 and Figure 7 As shown in the embodiments of

[0170] The housing body 12 includes: a first side plate 11, a second side plate 17, a front panel and a bottom plate 19. The first side plate 11 includes a first plate part 111 and a second plate part 112 which are arranged adjacent to each other at an angle. The first plate part 111 forms a part of the rear side wall of the housing 1, and the second plate part 112 forms the left side wall or the right side wall of the housing 1.

[0171] As Figure 2 shown, the first air inlet area 1111 is arranged on the first plate part 111 to avoid the setting of the first plate part 111 from affecting the air flow direction to the first heat exchange part 21, and to ensure that there is sufficient air flow around the outdoor heat exchanger 2 for heat exchange.

[0172] Referring to Figure 9 , the projection of the first heat exchange part 21 on the rear side wall of the housing 1 is located within the first plate part 111, so as to use the first plate part 111 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, and avoid the external environment from eroding and damaging the electric control box 4.

[0173] As Figure 2 and Figure 7 shown, the first air inlet area 1111 has a plurality of air inlets 14 arranged at intervals. The plurality of air inlets 14 can intake air stably, so as to provide air flow for the first heat exchange part 21 for heat exchange, or perform heat exchange with the structures arranged in the cavity defined between the first heat exchange part 21 and the housing 1 to realize the heat dissipation of the structures. The arrangement of the plurality of air inlets 14 is beneficial to increasing the air intake flow rate of the first air inlet area 1111 and ensuring that the first heat exchange part 21 has sufficient air flow for heat exchange.

[0174] Referring to Figure 2 , in the first air inlet area 1111, a plurality of air guiding plates 15 are arranged in parallel and at intervals. Each air guiding plate 15 is inclined relative to the horizontal plane. An air inlet 14 is defined between any two adjacent air guiding plates 15. Through the arrangement of the air guiding plates 15, external dust can be blocked, preventing dust and foreign objects from entering the cavity defined between the first heat exchange part 21 and the casing 1 through the air inlet 14, and improving the service life of the structure arranged in the cavity defined between the first heat exchange part 21 and the casing 1. Moreover, the air guiding plates 15 can guide the flow direction of the air flow, making the air flow flow to the position where heat exchange of the air flow is required.

[0175] In some embodiments, the air guiding plates 15 are inclined downward from the inside to the outside, so as to guide the air flow with a lower temperature at the lower part to the accommodation space 100, and better block the entry of dust moving from top to bottom.

[0176] Referring to Figure 2 , in the first air inlet area 1111, an air inlet grille 16 is provided. The air inlet grille 16 defines a plurality of air inlets 14. Through the arrangement of the air inlet grille 16, external dust can be blocked, preventing dust and foreign objects from entering the cavity defined between the first heat exchange part 21 and the casing 1 through the air inlet 14, improving the service life of the structure arranged in the cavity defined between the first heat exchange part 21 and the casing 1, and can guide the flow direction of the air flow to ensure that the air flow flows to the position where heat exchange of the air flow is required.

[0177] Referring to Figures 1 - 3 and Figure 7 , the casing 1 further includes a second side plate 17 disposed 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 respectively at both sides in the width direction. A second air inlet area 181 is formed on the back plate 18. The main heat exchange part 22 is disposed opposite to the back plate 18.

[0178] The air inlet part 101 further includes a third air inlet area 171 and the third air inlet area 171 is disposed on the second side plate 17. The second heat exchange part 23 is disposed opposite to the second side plate 17. The air flow 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 air flow for heat exchange and ensuring the heat exchange efficiency of the outdoor heat exchanger 2.

[0179] As Figure 16 shown, the electric control box 4 includes: an electric control main body 41 and a radiator 42. The electric control main body 41 can control the operation of the air conditioner outdoor unit 1000 in part. 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 that needs to be heat dissipated in the electric control box 4.

[0180] Among them, the radiator 42 is in contact with the electric control main body 41, so that the heat generated by the operation of the electrical components in the electric control main body 41 can be dissipated through the radiator 42. Moreover, the radiator 42 is disposed opposite to the first air inlet area 1111. Thus, the air flow entering the air conditioner outdoor unit 1000 from the first air inlet area 1111 will first pass through the radiator 42 and exchange heat with the radiator 42, which can not only ensure the flow rate of the air flow passing through the radiator 42, but also make the temperature of the air flow passing through the radiator 42 as low as possible, improving the heat dissipation effect of the electric control box 4.

[0181] Referring to Figure 17 , the radiator 42 includes a heat dissipation plate 421 and a plurality of heat dissipation fins 422. One side in the thickness direction of the heat dissipation plate 421 is in contact with the electric control main body 41 to achieve heat transfer. The heat dissipation plate 421 can integrate the plurality of heat dissipation fins 422. Thus, the heat generated by the operation of the electrical components in the electric control main body 41 can be transferred to the heat dissipation fins 422 through the heat dissipation plate 421 and exchange heat with the passing air flow at the heat dissipation fins 422, realizing sufficient heat dissipation of the electric control box 4.

[0182] As Figure 3 , Figure 4 , Figure 9 and Figure 12 shown, the heat dissipation plate 421 is placed vertically in the installation cavity 10, and a plurality of heat dissipation fins 422 are connected to the other side in the thickness direction of the heat dissipation plate 421 and are arranged at intervals in the up and down direction. A heat dissipation channel 423 is defined between two adjacent heat dissipation fins 422. The extending direction of the heat dissipation channel 423 is the horizontal direction, and the flowing direction of the air flow in the installation cavity 10 is also the horizontal direction. Thus, the air flow can evenly flow through each heat dissipation channel 423, ensuring that each heat dissipation fin 422 can fully contact the air flow and exchange heat, ensuring the heat dissipation effect of the electric control box 4. Moreover, the setting of the heat dissipation fins 422 does not block the air flow in the horizontal direction, avoiding the influence of the setting of the electric control box 4 on the flowing speed and flow rate of the air flow passing through the outdoor heat exchanger 2 and ensuring the heat exchange effect of the outdoor heat exchanger 2.

[0183] Referring to Figure 16 , the electric control main body 41 includes: a housing 411 and an electric control board 412. The electric control board 412 is placed vertically in the housing 411 to reduce the overall volume of the electric control box 4. The housing 411 protects the electric control board 412 outside the electric control board 412. At least a part of the radiator 42 is disposed in the housing 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 disposed outside the housing 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 be in direct contact with the air flow, avoid the air flow being blocked by the housing 411, and ensure that the radiator 42 can contact the air flow that first enters the installation cavity 10, ensuring the heat dissipation effect of the radiator 42.

[0184] As Figure 16 shown, the housing 411 includes: a mounting housing 4111 and a cover body 4112. The mounting housing 4111 and the cover body 4112 are separately provided to facilitate the installation and disassembly of the electronic control board 412, and to facilitate the molding of the housing 411, reducing the production and maintenance costs of the housing 411. Among them, the mounting housing 4111 is placed upright in the installation cavity 10 so that the entire electronic control box 4 can be placed upright in the installation cavity 10. The cover body 4112 is connected to one side of the mounting housing 4111 facing the first air inlet area 1111, and an opening is provided on the cover body 4112. The radiator 42 can extend to the outside of the housing 411 through the opening provided on the cover body 4112 and extend towards the direction close to the first air inlet area 1111, so that the radiator 42 can contact the intake air flow without obstruction, enabling the radiator 42 to better receive the intake air flow.

[0185] The electronic control board 412 is disposed between the mounting housing 4111 and the cover body 4112 to be protected by the cover body 4112 and the mounting housing 4111 between the mounting housing 4111 and the cover body 4112, preventing the structure on the electronic control board 412 from being damaged by the external environment.

[0186] Combined with Figure 4 、 Figure 16 and Figure 17 the embodiments shown, the radiator 42 has a limiting step 424. At least a part of the edge of the opening abuts against the limiting step 424 to limit at least a part of the radiator 42 within the housing 411, making the radiator 42 more stable, and at the same time reducing the need for unnecessary fasteners for the connection and limitation of the radiator 42. In other words, the overall installation of the electronic control box 4 can be achieved only by connecting the cover body 4112 and the mounting housing 4111 together, and the production and installation process is convenient.
