Description

Technical Field

[0001] This invention relates to the field of air conditioning equipment technology, and more particularly to an outdoor air conditioning unit and an air conditioner. Background Technology

[0002] An air conditioner generally consists of an indoor unit and an outdoor unit. The outdoor unit contains a fan, which generates air convection when it runs, allowing air to enter the outdoor unit to dissipate heat from the heat exchanger inside.

[0003] In related technologies, electronic control components are generally placed in the outdoor unit of the air conditioner for heat dissipation. The airflow that exchanges heat with the electronic control components flows first through the heat exchanger. The airflow exchanges heat with the heat exchanger, which causes the temperature of the airflow flowing to the electronic control components to rise. This results in poor heat exchange effect of the airflow on the electronic control components and affects the service life of the electronic control components. Summary of the Invention

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0061] The following is for reference. Figures 1-14 An outdoor unit 100 for an air conditioner according to an embodiment of the present invention is described.

[0062] Combination Figures 1-6 According to the present invention, the outdoor unit 100 of the air conditioner includes a housing 110 and a first partition 120. The first partition 120 is disposed inside the housing 110 and divides the inner cavity of the housing 110 into a first chamber 111 and a second chamber 112 arranged in a first direction.

[0063] The outdoor unit 100 of the air conditioner also includes an outdoor heat exchanger 130, a fan wheel 140, a compressor 150 and an electronic control assembly 160. The outdoor heat exchanger 130 and the fan wheel 140 are located in the first chamber 111, and the compressor 150 and the electronic control assembly 160 are located in the second chamber 112.

[0064] Specifically, in combination Figure 1 and Figure 2 An inner cavity is formed inside the outer shell 110. The first partition 120 can divide the inner cavity into a first chamber 111 and a second chamber 112 arranged along a first direction. The first chamber 111 is used to arrange the outdoor heat exchanger 130 and the fan wheel 140. The fan wheel 140 can rotate in the first chamber 111 and create a negative pressure to draw outdoor air into the first chamber 111 and discharge the airflow out of the outer shell 110.

[0065] Further integration Figure 5The compressor 150 is located in the second chamber 112. The first partition 120 can separate the outdoor heat exchanger 130 from the compressor 150 to reduce the thermal interference of the outdoor heat exchanger 130 to the compressor 150 and the electronic control component 160. At the same time, the electronic control component 160 is arranged in the second chamber 112 to reduce the thermal interference of the outdoor heat exchanger 130 to the electronic control component 160. It also facilitates the arrangement of the electronic control component 160 and improves the ease of disassembly and assembly of the electronic control component 160.

[0066] The first partition 120 has a first air passage 121 and a second air passage 122, both of which are connected to the first chamber 111. The first air passage 121 and the second air passage 122 are respectively provided with the first heat dissipation channel 161 and the second heat dissipation channel 162. The outer shell 110 has a first air inlet 113. The electronic control assembly 160 defines the first heat dissipation channel 161 and the second heat dissipation channel 162. The two ends of the first heat dissipation channel 161 are respectively connected to the first air inlet 113 and the first air passage 121. One end of the second heat dissipation channel 162 is connected to the second chamber 112 and the other end of the second heat dissipation channel 162 is connected to the second air passage 122.

[0067] Combination Figures 4 to 6 As the impeller 140 rotates, a local negative pressure is formed in the first chamber 111, allowing outdoor air to enter the outer casing 110 and further enter the first chamber 111 through the first air passage 121 and the second air passage 122, and then be discharged from the first chamber 111.

[0068] Specifically, the first air inlet 113 and the first air outlet 121 are connected through the first heat dissipation channel 161. Air entering the housing 110 from the first air inlet 113 can flow along the first heat dissipation channel 161 toward the first air outlet 121 and then enter the first chamber 111. During this process, the outdoor air flowing through the first heat dissipation channel 161 can dissipate heat from the electronic control component 160, reduce the risk of thermal failure of the electronic control component 160, and improve the working reliability of the electronic control component 160.

[0069] Furthermore, the second chamber 112 is connected to the outdoor environment, allowing outdoor air to enter the second chamber 112. One end of the second heat dissipation channel 162 is connected to the second chamber 112, and the other end of the second heat dissipation channel 162 is connected to the second air passage 122. The outdoor air entering the second chamber 112 can flow along the second heat dissipation channel 162 toward the second air passage 122 and then enter the first chamber 111. During this process, the outdoor air flowing through the second heat dissipation channel 162 can dissipate heat from the electronic control component 160, thereby further improving the heat dissipation efficiency of the electronic control component 160 and further reducing the risk of thermal failure of the electronic control component 160.

[0070] Outdoor air can enter the second chamber 112 through the gaps between the various plates of the outer casing 110 or through the air intake structure provided on the outer casing 110, thereby increasing the airflow (i.e. the airflow formed by the flow of outdoor air) entering the second chamber 112. After entering the second chamber 112, the airflow flows through the second heat dissipation channel to dissipate heat from the electronic control component 160, which is beneficial to further improve the heat dissipation efficiency of the electronic control component 160.

[0071] Meanwhile, the outdoor air entering the second chamber 112 can carry away the heat from components such as the compressor 150, which helps to improve the reliability of the outdoor unit 100.

[0072] In related technologies, the airflow that exchanges heat with the electronic control components flows through the heat exchanger, and the airflow exchanges heat with the heat exchanger, which causes the temperature of the airflow flowing to the electronic control components to rise. This results in poor heat exchange effect of the airflow on the electronic control components and affects the service life of the electronic control components.

[0073] This application uses a first separator 120 to separate the electronic control component 160 and the outdoor heat exchanger 130 into two separate chambers, thereby reducing the thermal interference of the outdoor heat exchanger 130 on the electronic control component 160. By defining a first heat dissipation channel 161 and a second heat dissipation channel 162 for the electronic control component 160, and connecting the first chamber 111 containing the outdoor heat exchanger 130 to the first air inlet 113 and the second chamber 114 through the first heat dissipation channel 161 and the second heat dissipation channel 162 respectively, airflow is prioritized to flow through the electronic control component 160 to dissipate heat from it. Since the temperature of the airflow flowing through the electronic control component 160 is low, the heat dissipation efficiency of the electronic control component 160 can be improved, reducing the risk of thermal failure of the electronic control component 160 and improving the operational reliability of the electronic control component 160.

[0074] Furthermore, the first chamber 111 is connected to the first air inlet 113 and the second chamber 112 through the first heat dissipation channel 161 and the second heat dissipation channel 162 respectively. Outdoor air is drawn in by the negative pressure generated by the rotation of the impeller 140. There is no need to set up a separate fan in the first heat dissipation channel 161 or the second heat dissipation channel 162, so as to reduce the structural complexity of the electronic control component 160, facilitate the processing and assembly of the electronic control component 160, help to realize the miniaturization design of the air conditioner outdoor unit 100, and reduce the production cost of the air conditioner outdoor unit 100.

[0075] According to the present invention, the outdoor unit 100 of the air conditioner connects the first chamber 111 and the first air inlet 113 by providing a first heat dissipation channel 161, and connects the first chamber 111 and the second chamber 112 by providing a second heat dissipation channel 162. When the fan wheel 140 rotates, it can draw outdoor air into the first heat dissipation channel 161 and the second heat dissipation channel 162 through the first air inlet 113 and the second chamber 112 to dissipate heat from the electronic control component 160. Since the air temperature is low when the air flows through the first heat dissipation channel 161 and the second heat dissipation channel 162, the heat dissipation efficiency of the electronic control component 160 can be effectively improved, the risk of thermal failure of the electronic control component 160 can be reduced, and the working reliability of the electronic control component 160 can be improved.

[0076] Combination Figure 4 and Figure 6 In some embodiments of the present invention, the outer casing 110 further has a second air inlet 114, and one end of the second heat dissipation channel 162 is connected to the second air inlet 114 through the second chamber 112.

[0077] Specifically, the second air inlet 114 is spaced apart from the first air inlet 113. One end of the second heat dissipation channel 162 is connected to the second air inlet 114 through the second chamber 112, and the other end of the second heat dissipation channel 162 is connected to the second air passage 112. Outdoor air can enter the second chamber 112 through the second air inlet 114.

[0078] Furthermore, the outdoor air entering the second chamber 112 from the second air inlet 114 can flow along the second heat dissipation channel 162 toward the second air outlet 122 and then enter the first chamber 111. During this process, the outdoor air flowing through the second heat dissipation channel 162 can dissipate heat from the electronic control component 160 to improve the heat dissipation efficiency of the electronic control component 160.

[0079] Therefore, by setting up the second air inlet 114 to increase the airflow, it is beneficial to further improve the heat dissipation efficiency of the electronic control component 160, reduce the risk of thermal failure of the electronic control component 160, and improve the working reliability of the electronic control component 160.

[0080] Combination Figure 4 and Figure 6 In some embodiments of the present invention, the outer shell 110 includes a first sidewall 115 and a second sidewall 116 that are adjacent to each other and arranged at an angle. The first sidewall 115 is arranged opposite to the first partition 120 in a first direction, and the first sidewall 115 is located on the side of the first partition 120 away from the first chamber 111.

[0081] Specifically, the first sidewall 115 can extend along the second direction, and the first sidewall 115 and the first partition 120 are disposed opposite to each other in the first direction, that is, the first sidewall 115 is located on the side of the first partition 120 away from the first chamber 111 and is spaced apart from the first partition 120 in the first direction. The second sidewall 116 can extend along the first direction, and the second sidewall 116 is connected to the first sidewall 115.

[0082] The first air inlet 113 is located on the first side wall 115, and the second air inlet 114 is located on the second side wall 116. On the one hand, the first air inlet 113 and the second air inlet 114 are arranged alternately, which facilitates the connection between the first heat dissipation channel 161 and the first air inlet 113. This helps to prevent the first heat dissipation channel 161 from blocking the second air inlet 114 and ensures the air intake effect of the second air inlet 114, thereby ensuring the fluidity of the airflow. On the other hand, it can form multi-sided air intake, which helps to increase the air volume used for heat exchange with the electronic control component 160, thereby further improving the heat dissipation efficiency of the electronic control component 160.

[0083] It should be noted that the first direction is perpendicular to the second direction. The "first direction" can be understood as the length direction of the outdoor unit 100, and the "second direction" can be understood as the thickness direction of the outdoor unit 100. For a specific directional diagram, please refer to [reference needed]. Figure 5 As shown.

[0084] The first sidewall 115 and the second sidewall 116 can be integrally formed, which can reduce the number of parts of the outer casing 110 and facilitate the assembly of the outdoor unit 100 of the air conditioner.

[0085] Combination Figure 1 and Figure 2 In some embodiments of the present invention, the housing 110 further includes a front panel 117 and a rear panel 118, the front panel 117 and the rear panel 118 being opposite to and spaced apart in a second direction, the end of the first sidewall 115 away from the second sidewall 116 in the second direction being connected to the front panel 117, and the second sidewall 116 being connected to the rear panel 118.

[0086] Furthermore, the housing 110 also includes a third sidewall 119, which is located on the side of the first partition 120 away from the second chamber 112, and the third sidewall 119 is disposed opposite to the first sidewall 115 in a first direction. The third sidewall 119 is used to connect the front panel 117 and the rear panel 118.

[0087] Thus, the front panel 117, the first side wall 115, the second side wall 116, the rear panel 118, and the third side wall 119 are connected in sequence and define the inner cavity to provide installation space for the outdoor heat exchanger 130, the impeller 140, the electrical control assembly 160, the compressor 150, and the first partition 120, and to protect the above components, thereby improving the service life of the outdoor heat exchanger 130, the impeller 140, the electrical control assembly 160, and the compressor 150.

[0088] Combination Figure 1 and Figure 5 In some embodiments of the present invention, the front panel 117 includes a first plate 1171 and a second plate 1172 arranged sequentially in a first direction. The size of the first plate 1171 in the first direction is smaller than that of the rear panel 118. One end of the first partition 120 in the second direction is connected to the outdoor heat exchanger 130, and the other end of the first partition 120 in the second direction is connected to the first plate 1171. The first partition 120, the rear panel 118, the third side wall 119 and the first plate 1171 define a first chamber 111. The first partition 120, the first side wall 115, the second side wall 116 and the second plate 1172 define a second chamber 112.

[0089] Furthermore, in the third direction, the projected area of ​​the first chamber 111 is larger than the projected area of ​​the second chamber 112. Since the outdoor heat exchanger 130 and the impeller 140 require a large installation space, by making the projected area of ​​the first chamber 111 larger than the projected area of ​​the second chamber 112, it can be effectively ensured that the first chamber 111 can meet the requirements for arranging the outdoor heat exchanger 130 and the impeller 140.

[0090] It should be noted that the third direction is perpendicular to the first and second directions respectively. The "third direction" can be understood as the height direction of the outdoor unit of the air conditioner (100). For a specific direction diagram, please refer to [reference needed]. Figure 5 As shown.

[0091] Furthermore, after the electronic control component 160 is installed in the second chamber 112, the second plate 1172 can shield the electronic control component 160 on the side away from the second side wall 116, thereby protecting the electronic control component 160 and improving its service life.

[0092] Combination Figure 2 , Figure 3 and Figure 5In some embodiments of the present invention, the electronic control component 160 is at least partially disposed above the compressor 150, and the electronic control component 160 is at least partially arranged with the compressor 150 in a second direction. The electronic control component 160 and the second sidewall 116 are disposed opposite each other in the second direction, and the compressor 150 is located between the electronic control component 160 and the second sidewall 116.

[0093] Specifically, at least a portion of the electronic control component 160 is located above the compressor 150 in the third direction. For example, the entire electronic control component 160 may be located above the compressor 150 to facilitate the arrangement of the electronic control component 160 and the compressor 150 and prevent them from interfering with each other during assembly. Alternatively, the portion of the electronic control component 160 that defines the first heat dissipation channel 161 may be flush with the compressor 150 in the third direction, which is beneficial to improving the space utilization of the housing 110 in the second direction, thereby helping to reduce the size of the outdoor unit 100 in the third direction and realizing the miniaturization design of the outdoor unit 100.

[0094] It is understandable that the specific arrangement of the electronic control component 160 and the compressor 150 can be determined according to actual production requirements, and no specific restrictions are made here.

[0095] Further reference Figure 4 The first air inlet 113 is located in the middle or upper part of the first side wall 115, and the second air inlet 114 is located in the lower part of the second side wall 116.

[0096] In other words, the first air intake 113 is located in the middle or upper part of the first side wall 115 in the third direction, so as to connect the first air intake 113 with the first heat dissipation channel 161, improve the assembly convenience of the air conditioner outdoor unit 100, and help prevent rainwater from splashing into the first heat dissipation channel 161 through the first air intake 113, thus preventing the electronic control component 160 from short-circuiting.

[0097] It should be noted that "middle" can refer to the exact center of the first sidewall 115 in the third direction, or it can refer to the position of the first sidewall 115 slightly below or slightly above the center in the third direction.

[0098] Further integration Figure 2 and Figure 3From the third-party perspective, the orthographic projection of the compressor 150 is located between the orthographic projection of the second side wall 116 and the orthographic projection of the electronic control component 160. The second air inlet 114 is located at the lower part of the second side wall 116. After the airflow enters the second chamber 112 through the second air inlet 114, it flows to the second heat dissipation channel 162. Since the electronic control component 160 is located above the compressor 150 and in front of the compressor 150, the airflow enters the second chamber 112 and flows forward and upward from the second side wall 116. During this process, the airflow flows through the compressor 150 and its pipelines and other structures. The airflow can carry away the heat of the compressor 150 and its pipelines and other structures, thereby achieving the cooling of the compressor 150 and its pipelines and other structures.

[0099] Meanwhile, the second air inlet 114 and the second heat dissipation channel 162 are spaced apart in the second direction and the third direction, which can effectively prevent rainwater from splashing into the second heat dissipation channel 162 through the second air inlet 114, which helps to reduce the risk of short circuit of the electronic control component 160 and ensure the working reliability of the electronic control component 160.

[0100] Combination Figure 2 and Figure 3 In some embodiments of the present invention, the first heat dissipation channel 161 includes an air inlet section 1611, a main body section 1612 and an air outlet section 1613, with the main body section 1612 connected between the air inlet section 1611 and the air outlet section 1613; the air inlet section 1611 is at least partially bent away from the second sidewall 116 to avoid the compressor 150.

[0101] Specifically, the air outlet section 1613 is connected to the first air passage section 121, the air inlet section 1611 is connected to the first air inlet section 113, and the main body section 1612 is used to connect the air outlet section 1613 and the air inlet section. The air inlet section 1611 includes a first section 1 and a second section 2 connected together. The first section 1 is connected to the main body section 1612, and the second section 2 is connected to the first air inlet section 113.

[0102] Furthermore, in the direction extending from the main body section 1612 toward the first air inlet section 113, the side of the first section 1 closest to the second sidewall 116 in the second direction bends toward a direction away from the second sidewall 116, so that at least a portion of the air inlet section 1611 bends toward a direction away from the second sidewall 116, thereby avoiding the compressor 150 and improving the assembly convenience of the compressor 150 and the electronic control assembly 160.

[0103] Furthermore, the second segment 2 extends obliquely from the first segment 1 toward the direction close to the second side wall 116, so that the first air inlet 113 is relatively close to the second side wall 116 in the second direction. This avoids a significant reduction in the structural strength of the first side wall 115 due to the first air inlet 113 being close to the front edge of the first side wall 115, which helps to ensure the structural strength of the first side wall 115 and reduces the risk of the first side wall 115 being crushed.

[0104] It should be noted that "front edge" refers to the edge of the first sidewall 115 that is away from the second sidewall 116 in the second direction.

[0105] Along the ventilation direction of the first heat dissipation channel 161, that is, the flow direction of the airflow within the first heat dissipation channel 161, the air outlet section 1613 extends toward the air inlet side near the impeller 140, so that the air outlet section 1613 can guide the airflow toward the air inlet side near the impeller 140, thereby further improving the airflow fluidity.

[0106] This allows the first heat dissipation channel 161 to avoid the compressor 150 while shortening its length, improving airflow efficiency, reducing airflow and temperature loss during flow, and improving the flow rate through the electronic control component 160, thereby enhancing the heat dissipation effect.

[0107] Optionally, the first heat dissipation channel 161 can be configured such that the air inlet section 1611 is at least partially bent in a direction away from the second sidewall 116, while the air outlet section 1613 extends toward the air inlet side close to the impeller 140 along the ventilation direction of the first heat dissipation channel 161, so that the first heat dissipation channel 161 avoids the compressor 150, and helps to ensure the structural strength of the first sidewall 115, while improving the flow of air.

[0108] It is understandable that the specific structure of the first heat dissipation channel 161 can be determined according to actual production requirements, and no specific limitation is made here.

[0109] Combination Figure 8 , Figure 9 , Figure 11 and Figure 12 In some embodiments of the present invention, the electronic control component 160 includes: a housing 163 and a circuit board 164. The circuit board 164 is placed upright inside the housing 163 and defines a first heat dissipation channel 161 and a second heat dissipation channel 162 between the circuit board 164 and the housing 163. The first heat dissipation channel 161 is located below the second heat dissipation channel 162. A heat sink 165 is provided in the first heat dissipation channel 161, and a heat-generating component 166 of the circuit board 164 is provided in the second heat dissipation channel 162.

[0110] Specifically, the circuit board 164 is placed vertically in the housing 163 along the third direction. The circuit board 164 is provided with a heat-generating component 166 and a heat sink 165. The heat-generating component 166 can cooperate with the heat-generating component 166 for heat transfer, and the heat sink 165 can dissipate heat from the heat-generating component 166.

[0111] Furthermore, the circuit board 164 and the housing 163 define a first heat dissipation channel 161 and a second heat dissipation channel 162 arranged in a third direction. The heat sink 165 is disposed in the first heat dissipation channel 161. Specifically, the heat sink 165 is located in the main body section 1612. Airflow can enter the air intake section 1611 through the first air intake 113 and flow from the air intake section 1611 into the main body section 1612 to exchange heat with the heat sink 165, thereby carrying away the heat from the heat sink 165 and improving the heat dissipation effect of the electronic control component 160.

[0112] It should be noted that the method of "heat transfer coordination" is not specifically limited. For example, it can be direct or indirect contact heat transfer, or geothermal radiation heat transfer with a small gap, etc.

[0113] Combination Figure 5 and Figure 12 In some embodiments of the present invention, the housing 163 includes: a first housing 1631 and a second housing 1632, the first housing 1631 and the second sidewall 116 being disposed opposite to each other in a second direction, the first housing 1631 and the second housing 1632 being disposed opposite to each other and connected in the second direction, and the second housing 1632 being located between the first housing 1631 and the second sidewall 116 in the second direction.

[0114] Specifically, the first shell 1631 and the second shell 1632 are engaged and connected in the second direction. A mounting cavity is defined between the first shell 1631 and the second shell 1632. The mounting cavity is used to arrange structures such as the circuit board 164, the heat sink 165, and the heat-generating component 166. At the same time, the first shell 1631 and the second shell 1632 can also shield the circuit board 164, the heat sink 165, and the heat-generating component 166 to protect them.

[0115] By arranging the first housing 1631 and the second sidewall 116 opposite each other in the second direction, when the electronic control component 160 needs to be repaired, the front panel 117 is removed first, and then the electronic control component 160 can be removed along the second direction, or the first housing 1631 of the electronic control component 160 can be removed, which helps to improve the convenience of disassembly and repair of the electronic control component 160.

[0116] Further integration Figure 13 and Figure 14The housing 163 also includes a second partition 1633, which is disposed between the first housing 1631 and the second housing 1632. The second partition 1633, together with the first housing 1631, the second housing 1632 and the circuit board 164, defines the first heat dissipation channel 161 and the second heat dissipation channel 162.

[0117] The second separator 1633 is disposed at the lower part of the housing 163 to define, together with the first housing 1631, the second housing 1632 and the circuit board 164, the first heat dissipation channel 161 and the second heat dissipation channel 162 arranged in a third direction. The second separator 1633 can separate the first heat dissipation channel 161 and the second heat dissipation channel 162 to form two independent heat dissipation channels, which helps to prevent airflow turbulence.

[0118] Reference Figure 8 and Figure 12 In some embodiments of the present invention, there are gaps at both ends of the first shell 1631 and the second shell 1632 in a first direction to allow airflow to pass through.

[0119] Specifically, the first shell 1631 and the second shell 1632 are fastened together in the second direction and open at both ends in the first direction. The first heat dissipation channel 161 is open at both ends in the first direction and is connected to the first air inlet 113 and the first air outlet 121 respectively, so as to ensure that airflow can flow into the first heat dissipation channel 161 through the first air inlet 113 and flow into the first chamber 111 from the first heat dissipation channel 161 through the first air outlet 121.

[0120] Furthermore, the second heat dissipation channel 162 is open at both ends in the first direction, and one end of the second heat dissipation channel 162 is connected to the second chamber 112, while the other end of the second heat dissipation channel 162 is connected to the second air passage 122, so as to ensure that airflow can flow into the first chamber 111 through the second heat dissipation channel 162 and ensure the fluidity of airflow.

[0121] Combination Figure 9 and Figure 10 In some embodiments of the present invention, the top of one of the first shell 1631 and the second shell 1632 is provided with a first slot 1634, and the top of the other is provided with a first insertion part 1635 that engages with the first slot 1634. One of the groove wall of the first slot 1634 and the first insertion part 1635 is provided with a first snap-fit ​​part 1636, and the other is provided with a first snap-fit ​​groove 1637 that engages with the first snap-fit ​​part 1636.

[0122] For example, the top of the second shell 1632 is provided with a first slot 1634. The first slot 1634 is open on the side away from the second shell 1632 along the second direction, that is, the first slot 1634 is open to the first shell 1631. The top of the first shell 1631 is provided with a first insertion part 1635. The first insertion part 1635 can be inserted into the first slot 1634, thereby realizing the positioning and engagement of the first shell 1631 and the second shell 1632, which facilitates the assembly of the first shell 1631 and the second shell 1632.

[0123] The first insertion part 1635 can be configured as a flange structure formed on the top of the first shell 1631. The flange structure extends along the second direction toward the direction close to the second shell 1632, and the flange structure can be inserted into the first slot 1634 to achieve the positioning and engagement of the first shell 1631 and the second shell 1632.

[0124] Optionally, the first slot 1634 can be formed on the second housing 1632, and the first insertion part 1635 can be formed on the first housing 1631. This structural arrangement can achieve the same technical effect as the above structure, and will not be described in detail here.

[0125] Furthermore, a first snap-fit ​​portion 1636 may be formed on the wall of the first slot 1634, and a first slot 1637 may be formed on the first insertion portion 1635. When the first insertion portion 1635 is inserted into the first slot 1634, the first snap-fit ​​portion 1636 may engage with the first slot 1637 in the second direction to ensure the reliability of the positioning engagement between the first shell 1631 and the second shell 1632.

[0126] The first snap-fit ​​portion 1636 can be configured as an elastic snap-fit ​​protrusion. The first snap-fit ​​portion 1636 can be disposed on the first insertion portion 1635 and extend downward in a third direction. The first slot 1637 can be formed on the bottom groove wall of the first slot 1634. During the insertion and engagement of the first insertion portion 1635 and the first slot 1634, the first snap-fit ​​portion 1636 and the first slot 1634 abut against each other and undergo elastic deformation to ensure that the first insertion portion 1635 and the first slot 1634 can be inserted into place. After the first insertion portion 1635 and the first slot 1634 are inserted, the first snap-fit ​​portion 1636 snaps into the first slot 1637 and returns to its original deformation. At this time, the first snap-fit ​​portion 1636 and the first slot 1637 can abut against each other in a second direction to ensure the reliability of the engagement between the first shell 1631 and the second shell 1632.

[0127] The bottom of one of the first shell 1631 and the second shell 1632 is provided with a second slot 1638, and the bottom of the other shell is provided with a second insertion part 1639 that engages with the second slot 1638. The groove wall of the second slot 1638 and the second insertion part 1639 are provided with a second snap-fit ​​part 1640, and the other shell is provided with a second snap-fit ​​groove 1641 that engages with the second snap-fit ​​part 1640.

[0128] For example, the bottom of the second shell 1632 is provided with a second slot 1638, which opens in a second direction away from the second shell 1632, that is, the second slot 1638 opens towards the first shell 1631. The bottom of the first shell 1631 is provided with a second insertion part 1639, which can be inserted into the second slot 1638, thereby realizing the positioning and cooperation of the first shell 1631 and the second shell 1632, which facilitates the assembly of the first shell 1631 and the second shell 1632.

[0129] The second insertion part 1639 can be configured as a flange structure formed at the bottom of the first shell 1631. The flange structure extends along the second direction toward the second shell 1632, and the flange structure can be inserted into the second slot 1638 to achieve the positioning and engagement of the first shell 1631 and the second shell 1632.

[0130] A second slot 1641 can be formed on the wall of the second slot 1638, and a second snap-fit ​​portion 1640 can be formed on the second insertion portion 1639. When the second insertion portion 1639 is inserted into the second slot 1638, the second snap-fit ​​portion 1640 can engage with the second slot 1641 in the second direction to ensure the reliability of the positioning engagement between the first shell 1631 and the second shell 1632.

[0131] Optionally, one of the first shell 1631 and the second shell 1632 is provided with a first slot 1634 at the top and a second slot 1638 at the bottom, while the other of the first shell 1631 and the second shell 1632 is provided with a first insertion part 1635 at the top and a second insertion part 1639 at the bottom, so as to ensure that the first shell 1631 and the second shell 1632 can be positioned and engaged on both sides in the third direction, thereby further improving the engagement effect of the first shell 1631 and the second shell 1632.

[0132] Combination Figure 13 and Figure 14In some embodiments of the present invention, at least one of the first shell 1631 and the second shell 1632 includes: a shell body 1642, a first upper flange 1643, a second upper flange 1644, and a lower flange 1645. The first upper flange 1643 and the second upper flange 1644 are arranged in a first direction and are both connected to the upper end of the shell body 1642. The first upper flange 1643 is located below the second upper flange 1644, and the lower flange 1645 is connected to the lower end of the shell body 1642.

[0133] Specifically, the shell body 1642 extends along a third direction, and the portion of the shell body 1642 near the first air inlet 113 bends away from the second side wall 116 along a second direction to avoid the compressor 150, thereby preventing the electronic control component 160 and the compressor 150 from interfering with each other during assembly and ensuring the ease of assembly of the electronic control component 160 and the compressor 150.

[0134] Furthermore, in the first direction, the first upper flange 1643 is disposed relatively close to the first sidewall 115, and the second upper flange 1644 is disposed relatively close to the first separator 120. The orthographic projection of the first upper flange 1643 is located between the projection surfaces of the second upper flange 1644 and the lower flange 1645. That is, the distance between the first upper flange 1643 and the lower flange 1645 in the third direction is less than the distance between the second upper flange 1644 and the lower flange 1645 in the third direction. The circuit board 164, the heat-generating component 166, the heat sink 165, and the second separator 1633 are located between the second upper flange 1644 and the lower flange 1645.

[0135] The shell body 1642, the first upper flange 1643, and the lower flange 1645 are adapted to define at least a portion of the first heat dissipation channel 161. The shell body 1642, the second upper flange 1644, and the second partition 1633 are adapted to define at least a portion of the second heat dissipation channel 162. The space above the first upper flange 1643 is a reserved air passage space. The air passage space is directly opposite the second heat dissipation channel 162 in the first direction to avoid the first upper flange 1643 blocking the inlet of the second heat dissipation channel 162 and to ensure the smooth air intake of the second heat dissipation channel 162.

[0136] For example, when only the first shell 1631 includes the shell body 1642, the first upper flange 1643, the second upper flange 1644, and the lower flange 1645, the shell body 1642, the first upper flange 1643, and the lower flange 1645 can define a portion of the first heat dissipation channel 161 located near the first air inlet 113, and this portion of the first heat dissipation channel 161 is open to the side facing the second shell 1632. At the same time, the shell body 1642, the second upper flange 1644, and the second partition 1633 define a portion of the second heat dissipation channel 162 open to the side facing the second shell 1632. The second shell 1632 can be constructed as a straight plate structure to facilitate the processing of the shell 163.

[0137] When only the second shell 1632 includes the shell body 1642, the first upper flange 1643, the second upper flange 1644, and the lower flange 1645, the shell body 1642, the first upper flange 1643, and the lower flange 1645 define a portion of the first heat dissipation channel 161 located near the first air inlet 113, and this portion of the first heat dissipation channel 161 is open to one side facing the second shell 1632. At the same time, the shell body 1642, the second upper flange 1644, and the second separator 1633 define a portion of the second heat dissipation channel 162 that is open to one side facing the first shell 1631.

[0138] When both the first shell 1631 and the second shell 1632 include a shell body 1642, a first upper flange 1643, a second upper flange 1644, and a lower flange 1645, the first shell 1631 and the second partition 1633 cooperate to define a portion of the second heat dissipation channel 162 that is open toward the second shell 1632, and the second shell 1632 and the second partition 1633 cooperate to define a portion of the second heat dissipation channel 162 that is open toward the first shell 1631. The first shell 1631 and the second shell 1632 are fastened together to define the entire second heat dissipation channel 162. Similarly, the first shell 1631 and the second shell 1632 are fastened together to form the entire first heat dissipation channel 161.

[0139] Combination Figure 13 and Figure 14 In some embodiments of the present invention, the second partition 1633 defines a receiving cavity 331, which is part of the first heat dissipation channel 161. The receiving cavity 331 has a first opening at both ends in a first direction and a second opening on the side opposite to the second shell 1632. The radiator 165 is at least partially disposed in the receiving cavity 331 and closes the second opening. The radiator 165 includes a plurality of heat dissipation fins 1651, and an airflow gap is formed between two adjacent heat dissipation fins 1651 for airflow to pass through. The two ends of the airflow gap are correspondingly connected to the two first openings.

[0140] Specifically, the first opening of the receiving cavity 331 near the first sidewall 115 in the first direction is connected to the first air inlet 113, and the first opening of the receiving cavity 331 near the first partition 120 in the first direction is connected to the first air outlet 121.

[0141] Furthermore, the receiving cavity 331 forms a second opening on the side near the second shell 1632 in the second direction. The radiator 165 can be disposed in the receiving cavity 331 through the second opening and the second opening is closed to prevent the airflow flowing into the receiving cavity 331 from flowing into the second heat dissipation channel 162 located on the upper side of the second partition 1633 through the second opening, thereby preventing airflow turbulence.

[0142] Meanwhile, after the airflow enters the receiving cavity 331 through the first open opening near the first side wall 115, it flows through multiple heat sinks 1651 through the gap between two adjacent heat sinks 1651, allowing the airflow to fully contact the heat sinks 1651 to improve the heat dissipation efficiency of the radiator 165. The airflow after heat exchange can flow to the first air passage 121 through the first open opening near the first partition 120, and then flow into the first chamber 111 through the first air passage 121 and then be discharged from the first chamber 111.

[0143] Combination Figure 9 and Figure 13 In some embodiments of the present invention, the second separator 1633 includes a connecting plate 336, a support plate 337, and a separator 338. The connecting plate 336 is disposed opposite to and connected to the first shell 1631 in a second direction. One end of the support plate 337 is connected to the lower end of the connecting plate 336, and the other end of the support plate 337 extends toward the direction close to the second shell 1632. The support plate 337 is supported on the inner wall of the first shell 1631 or the second shell 1632. One end of the separator 338 is connected to the upper end of the connecting plate 336, and the other end of the separator 338 extends toward the direction close to the second shell 1632.

[0144] Specifically, the support plate 337 and the partition plate 338 are respectively connected to the two ends of the connecting plate 336 in the third direction. That is, the second partition 1633 extends in a roughly U-shaped structure. The partition plate 338 is used to separate the receiving cavity 331 from the second heat dissipation channel 162 in the third direction to prevent airflow turbulence. At the same time, it can prevent rainwater from splashing into the receiving cavity 331 through the first air inlet 113 and then further entering the second heat dissipation channel 162 to contact the heat-generating component 166, thereby preventing the heat-generating component 166 from short-circuiting and improving the working stability of the heat-generating component 166.

[0145] Furthermore, the support plate 337 is disposed at the lower end of the connecting plate 336 and supported on the inner wall of the first shell 1631 or the second shell 1632 to improve the stability of the connecting plate 336, prevent the connecting plate 336 from shifting, and thereby reduce the risk of the connecting plate 336 crushing the radiator 165.

[0146] Combination Figure 8 and Figure 13 In some embodiments of the present invention, the second separator 1633 is provided with a positioning protrusion 334 at a position opposite to the first shell 1631, and the first shell 1631 is provided with a positioning hole 311 that cooperates with the positioning protrusion 334.

[0147] For example, the second partition 1633 includes a connecting plate 336, a support plate 337, and a partition plate 338. A positioning protrusion 334 can be disposed on the connecting plate 336 and located on the side of the connecting plate 336 opposite to the first shell 1631. The positioning protrusion 334 protrudes from the connecting plate 336 toward the first shell 1631 along a second direction. Correspondingly, a positioning hole 311 is formed on the first shell 1631. The positioning hole 311 is disposed opposite to the positioning protrusion 334 in the second direction. The positioning protrusion 334 can be inserted into the positioning hole 311 to realize the positioning and installation of the second partition 1633 and the first shell 1631, which is beneficial to improve the assembly convenience of the second partition 1633 and the first shell 1631.

[0148] The second separator 1633 has a first profile 335 on the side facing the first shell 1631, and the first shell 1631 is provided with a second profile 312 that matches the first profile 335.

[0149] For example, a first pressing pattern 335 may be formed on the second separator 1633, the first pressing pattern 335 protruding towards the side close to the first shell 1631, and a second pressing pattern 312 may be formed on the first shell 1631, the second pressing pattern 312 protruding away from the second separator 1633, and a groove structure is formed on the side of the second pressing pattern 312 opposite to the second separator 1633, and the shapes of the first pressing pattern 335 and the second pressing pattern 312 are adapted to each other so that the first pressing pattern 335 can be embedded in the second pressing pattern 312. For example, both the first pressing pattern 335 and the second pressing pattern 312 can be constructed as rectangular pressing patterns. During the installation of the first shell 1631, the first pressing pattern 335 and the second pressing pattern 312 can be used to position and install the first shell 1631 and the second separator 1633, which is beneficial to improving the assembly convenience of the first shell 1631 and the second separator 1633.

[0150] Optionally, the second partition 1633 is provided with a positioning protrusion 334, and the second partition 1633 is also provided with a first pressing mold 335. The first pressing mold 335 and the positioning protrusion 334 are spaced apart. Correspondingly, the first shell 1631 is formed with a positioning hole 311 opposite to the positioning protrusion 334, and the first shell 1631 is also provided with a second pressing mold 312, so as to further improve the positioning and installation effect of the first shell 1631 and the second partition 1633 and improve the assembly convenience of the first shell 1631 and the second partition 1633.

[0151] Combination Figure 6 and Figure 7 In some embodiments of the present invention, the first partition 120 has a mounting flange 123 extending toward the second chamber 112, and the electronic control assembly 160 is connected at one end to the mounting flange 123 in a first direction and at the other end to the first sidewall 115.

[0152] Specifically, the mounting flange 123 is disposed opposite to the housing 163 of the electronic control assembly 160. For example, the mounting flange 123 can be disposed opposite to the housing 163 in the second direction so as to connect the mounting flange 123 to the housing 163, thereby facilitating the connection of one end of the electronic control assembly 160 in the first direction to the first separator 120.

[0153] Furthermore, the end of the housing 163 away from the first partition 120 in the first direction is connected to the first sidewall 115. For example, the end of the housing 163 away from the first partition 120 in the first direction may be formed with a flange structure. The flange structure may be parallel to and opposite to the first sidewall 115 so that the flange structure can be connected to the first sidewall 115, thereby facilitating the connection of the electronic control component 160 to the first sidewall 115.

[0154] Thus, the assembly of the electronic control component 160 is realized, and by connecting the two ends of the electronic control component 160 in the first direction to the first separator 120 and the first sidewall 115 respectively, the assembly stability of the electronic control component 160 is improved.

[0155] In some embodiments of the present invention, the electronic control component 160 is provided with a hook 321 on the side facing the second sidewall 116, and the mounting flange 123 is provided with a locking hole that cooperates with the hook 321.

[0156] For example, the hook 321 can be disposed on the second housing 1632, and the hook 321 can extend from the second housing 1632 toward the direction close to the second side wall 116. The mounting flange 123 can be located on the side of the hook 321 that is relatively close to the second side wall 116, and the locking hole is disposed opposite to the hook 321. The hook 321 can extend into the locking hole and engage with the mounting flange 123, thereby realizing the connection between the electronic control component 160 and the mounting flange 123. The engaging method facilitates the disassembly and assembly of the electronic control component 160, which helps to improve the convenience of disassembly, assembly and maintenance of the electronic control component 160.

[0157] Combination Figure 7 and Figure 9 In other examples, the hook 321 can engage with the upper flange of the mounting flange 123 to connect the electronic control component 160 to the mounting flange 123. This facilitates the assembly and disassembly of the electronic control component 160 without the need to machine holes in the mounting flange 123, which simplifies the processing steps of the first separator 120 and reduces the processing difficulty of the first separator 120.

[0158] Reference Figure 14 The electronic control component 160 has a first connection hole 169, and the mounting flange 123 and / or the first sidewall 115 are provided with a second connection hole. The electronic control component 160 is fixed in the second chamber 112 by fasteners, which pass through the first connection hole 169 and the second connection hole (not shown).

[0159] For example, a first connecting hole 169 may be formed on the second housing 1632 and may extend through the second housing 1632 in a second direction. A second connecting hole is formed on the mounting flange 123 and extends through the mounting flange 123 in a second direction. A fastener extends in a second direction or extends obliquely relative to the second direction. The fastener passes through the first connecting hole 169 and the second connecting hole and connects the mounting flange 123 to the second housing 1632. The fastener may be a screw or bolt, etc.

[0160] When the electronic control assembly 160 needs to be repaired, the front panel 117 is removed first (specifically, the second panel 1172 is removed first) so that the fasteners can be unscrewed from the first connection hole 169 and the second connection hole, thereby facilitating the disassembly of the electronic control assembly 160 from the mounting flange 123.

[0161] A second connecting hole may be provided on the first side wall 115. Fasteners are inserted through the first connecting hole 169 and the second connecting hole and connect the electronic control component 160 to the first side wall 115. When the electronic control component 160 needs to be disassembled and repaired, the fasteners can be unscrewed from the first connecting hole 169 and the second connecting hole, so as to facilitate the disassembly of the electronic control component 160 from the first side wall 115.

[0162] The first sidewall 115 and the mounting flange 123 can be simultaneously formed with a second connecting hole. The electronic control component 160 is provided with at least two first connecting holes 169, and the first connecting holes 169 and the second connecting holes are provided in a one-to-one correspondence. Fasteners are passed through the first connecting holes 169 and the second connecting holes and connect the electronic control component 160 to the first sidewall 115 and the mounting flange 123 respectively.

[0163] Optionally, the electronic control component 160 may be provided with a hook 321 and a first connecting hole 169, with the hook 321 and the first connecting hole 169 spaced apart. The mounting flange 123 may be provided with a spaced-apart hook hole and a second connecting hole, and the first sidewall 115 may be provided with a second connecting hole. The electronic control component 160 may be detachably connected to the mounting flange 123 via the hook 321 and fasteners, and the electronic control component 160 may be connected to the first sidewall 115 via fasteners, thereby improving the assembly reliability of the electronic control component 160 and preventing the electronic control component 160 from falling off.

[0164] Combination Figure 8 and Figure 14 In some embodiments of the present invention, the top of the housing 163 of the electronic control component 160 is provided with a terminal block mounting portion 168. The terminal block mounting portion 168 is located above the first heat dissipation channel 161 and between the inlet of the first side wall 115 and the second heat dissipation channel 162. The terminal block mounting portion 168 extends downward at least partially in a direction away from the second side wall 116 for mounting a terminal block.

[0165] Specifically, the second heat dissipation channel 162 is open at one end near the first side wall 115 and forms the inlet of the second heat dissipation channel 162. Airflow can enter the second heat dissipation channel 162 from the second chamber 112 through the inlet. The terminal block mounting part 168 is disposed on the second shell 1632, and in the first direction, the terminal block mounting part 168 is located between the first side wall 115 and the inlet of the second heat dissipation channel 162.

[0166] Furthermore, the terminal block mounting portion 168 includes a connecting section 1682 and a mounting section 1681. The connecting section 1682 is connected to the top of the second housing 1632 and extends in a third direction away from the second housing 1632. The mounting section 1681 is connected to the side of the connecting section 1682 away from the second housing 1632, and the mounting section 1681 extends downward from the connecting section 1682 towards the second side wall 116 at an angle, so as to facilitate the positioning and installation of the terminal block on the terminal block mounting portion 168, improve the assembly convenience of the terminal block, and help prevent the terminal block from interfering with the front panel 117 and prevent the front panel 117 from pressing against the terminal block.

[0167] Therefore, by setting the terminal block mounting part 168 on the housing 163 of the electronic control component 160, it is convenient to disassemble and repair the terminal block and the wiring harness. When it is necessary to repair the terminal block or the wiring harness, the wiring harness or the terminal block can be repaired after the front panel 117 is removed, and there is no need to set up an additional structure for installing the terminal block mounting part 168, which helps to reduce the production cost of the air conditioner outdoor unit 100.

[0168] Combination Figures 5 to 7 In some embodiments of the present invention, the first air inlet 113, the second air inlet 114, the first air passage 121 and the second air passage 122 are all grille structures. The grille structure can prevent external debris, garbage and other objects from entering the air conditioner outdoor unit 100 while ensuring the flow of air, thereby reducing the risk of damage to the internal structure of the air conditioner outdoor unit 100.

[0169] The first air passage 121 and the second air passage 122 can be integrally formed to facilitate the processing of the first partition 120.

[0170] An air conditioner according to an embodiment of the present invention includes the above-described outdoor unit 100.

[0171] Since the air conditioner is equipped with the aforementioned outdoor unit 100, a first heat dissipation channel 161 is provided to connect the first chamber 111 and the first air inlet 113, and a second heat dissipation channel 162 is provided to connect the first chamber 111 and the second air inlet 114. When the fan wheel 140 rotates, it can draw outdoor air into the first heat dissipation channel 161 and the second heat dissipation channel 162 through the first air inlet 113 and the second air inlet 114 to dissipate heat from the electronic control component 160. Since the air temperature is low when the air flows through the first heat dissipation channel 161 and the second heat dissipation channel 162, the heat dissipation efficiency of the electronic control component 160 can be effectively improved. Furthermore, the first air inlet 113 and the second air inlet 114 are respectively provided on the outer casing 110 to effectively increase the airflow, further improve the heat dissipation efficiency of the electronic control component 160, reduce the risk of thermal failure of the electronic control component 160, and improve the working reliability of the electronic control component 160.
