[0039] The embodiments of the present application are described below in detail, examples of which are shown in the drawings, wherein the same or similar notations represent 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 only, for the purpose of explanation, and are not to be understood as a limitation of the present application.

[0040] The following description refers to the accompanying drawings. Figures 1-10 The air conditioner outdoor unit 100 according to an embodiment of the present application is described below, which is usually arranged outdoors.

[0041] The air conditioner outdoor unit 100 according to an embodiment of the present application includes a shell assembly 20 and an electric control box 10, and the shell assembly 20 serves as a mounting carrier for devices (such as a compressor 41, a fan 51, and the electric control box 10, etc.) in the air conditioner outdoor unit 100.

[0042] The shell assembly 20 has a cavity, and a partition plate 30 is arranged in the cavity. The partition plate 30 can separate the cavity and form adjacent compressor cavities 201 and fan cavities 202. The shell assembly 20 is provided with an air inlet portion 203 communicating with the compressor cavities 201. Air outside the shell assembly 20 can flow into the compressor cavities 201 through the air inlet portion 203. Ventilation holes 301 are formed on the partition plate 30 and are arranged through the thickness direction and communicate the compressor cavities 201 and the fan cavities 202. The ventilation holes 301 can communicate the fan cavities 202 and the compressor cavities 201, so that air on one side of the compressor cavities 201 can flow into the fan cavities 202 through the ventilation holes 301.

[0043] Referring to Figure 3 The electric control box 10 includes the electric control assembly 1 and the box assembly 15 mounted at the partition plate 30. The box assembly 15 forms first and second air ducts 101 and 102 respectively having independent air inlets and outlets. The first air inlet 1011 of the first air duct 101 and the second air inlet 1021 of the second air duct 102 respectively communicate with the compressor cavities 201. The first air outlet 1012 of the first air duct 101 and the second air outlet 1022 of the second air duct 102 respectively communicate with the ventilation holes 301. Thus, air in the compressor cavities 201 can flow into the first and second air ducts 101 and 102 through the first and second air inlets 1011 and 1021 respectively, and be discharged to the ventilation holes 301 through the first and second air outlets 1012 and 1022 after flowing through the first and second air ducts 101 and 102.

[0044] Further, the electric control assembly 1 is arranged in the box assembly 15, and part of the electric control assembly 1 is arranged in the first air duct 101 and part of the electric control assembly 1 is arranged in the second air duct 102. That is, the devices in the electric control assembly 1 can be arranged in the corresponding air duct structure according to the heat dissipation requirements of the devices, so as to meet the heat dissipation requirements of the electric control box 10.

[0045] It can be understood that the electric control assembly 1 can include power devices 112, capacitive devices 121 and other devices to realize the electric control function of the electric control box 10. The devices can be arranged in the first and second air ducts 101 and 102 in the box assembly 15 and cooled by air flowing through the first and second air ducts 101 and 102, so as to meet the heat dissipation requirements of the electric control box 10 and improve the heat dissipation efficiency of the electric control box 10.

[0046] The first air duct 101 and the second air duct 102 are two independent air duct structures, so that the air in the first air duct 101 and the air in the second air duct 102 can be prevented from interfering with each other, and the heat dissipation efficiency of the electric control assembly 1 is improved. That is, the air in the compressor cavity 201 can flow into the side of the fan cavity 202 through the ventilation hole 301 after flowing through the first air duct 101 and the second air duct 102, respectively, so that the air can be prevented from flowing through other devices again after flowing through part of the devices (i.e., the air temperature is increased), thereby causing the heat dissipation effect of the devices downstream of the air flow path to be poor.

[0047] Therefore, by arranging multiple air duct structures that are independent of each other and communicate between the compressor cavity 201 and the fan cavity 202 in the box assembly 15, the air in the compressor cavity 201 can flow into the side of the fan cavity 202 after flowing through the air duct structures in the box assembly 15, thereby achieving heat dissipation and cooling of the electric control assembly 1 in the electric control box 10, meeting the heat dissipation requirement of the electric control box 10 while improving the heat dissipation efficiency.

[0048] It can be understood that in the air conditioner outdoor unit 100, the fan 51 is arranged in the fan cavity 202, and the air in the fan cavity 202 can be discharged to the outside of the shell assembly 20 under the action of the fan 51, so that the air conditioner outdoor unit 100 has a rapid airflow on the side of the fan cavity 202, thereby forming a negative pressure at the ventilation hole 301, and the air in the compressor cavity 201 can flow to the side of the fan cavity 202 through the ventilation hole 301. Therefore, heat dissipation and cooling of the electric control box 10 can be achieved by air cooling, without the need to arrange a cooling pipeline structure cooperating with the electric control box 10, thereby facilitating the arrangement of the electric control box 10 in the shell assembly 20.

[0049] The compressor cavity 201 communicates with the outside of the shell assembly 20 through the air inlet portion 203, and when the air in the compressor cavity 201 flows to the side of the fan cavity 202 through the ventilation hole 301, the air inlet portion 203 can supplement air into the compressor cavity 201, thereby achieving air circulation on the side of the compressor cavity 201 and ensuring the heat dissipation and cooling effect of the electric control box 10.

[0050] It should be noted that at present, the electric control box 10 is arranged in the shell of the air conditioner outdoor unit 100 to control the operation state of the devices in the air conditioner outdoor unit 100. In the related art, the electric control box 10 in the air conditioner outdoor unit 100 is cooled and cooled by a low-temperature pipeline and other components, thereby limiting the arrangement position of the electric control box 10 in the air conditioner outdoor unit 100, and the electric control box 10 is not convenient for disassembly, maintenance, and other operations.

[0051] In the present application, the air duct structure (i.e., the first air duct 101 and the second air duct 102) is arranged at the electric control box 10, and the air on the side of the compressor cavity 201 can flow to the side of the fan cavity 202 after flowing through the air duct structure, so that the electric control assembly 1 in the electric control box 10 can be cooled by air cooling, without the need to arrange a low-temperature pipeline structure corresponding to the electric control box 10 in the air conditioner outdoor unit 100, and the electric control box 10 can be assembled at the middle partition plate 30, which can reduce the disassembly and assembly difficulty of the electric control box 10. At the same time, the first air duct 101 and the second air duct 102 are formed in the electric control box 10, and the devices in the electric control assembly 1 can be arranged in the first air duct 101 and the second air duct 102 according to the heat dissipation requirement, so as to ensure the heat dissipation and cooling efficiency of the air to the electric control assembly 1, and improve the heat dissipation and cooling effect of the electric control box 10.

[0052] As shown in Figure 3 , in some embodiments of the present application, the middle partition plate 30 is arranged in the shell assembly 20 from front to back to separate the cavity of the shell assembly 20 to form the compressor cavity 201 and the fan cavity 202 arranged along the first direction. The first direction is the left-right direction of the outdoor unit.

[0053] As shown in Figure 1 and Figure 4 , in some embodiments of the present application, the shell assembly 20 includes a shell body 21 and a panel 22, the shell body 21 is open to one side in the second direction, and the panel 22 is detachably mounted on the open side of the shell body 21, and the panel 22 and the shell body 21 define the above-mentioned cavity, and the electric control box 10 is connected to the side of the middle partition plate 30 close to the panel 22.

[0054] The second direction is the front-rear direction of the air conditioner outdoor unit 100, the panel 22 is arranged on the front side of the shell assembly 20, and the panel 22 is formed with an air outlet structure communicating with the fan cavity 202 to meet the air outlet requirement on the side of the fan cavity 202 while shielding the devices arranged in the shell assembly 20 (such as the fan 51, the compressor 41, etc.).

[0055] As shown in Figure 4 , the compressor 41 and the pipeline 42 are arranged in the compressor cavity 201, the fan 51 and the heat exchanger 52 are arranged in the fan cavity 202, and the fan 51 can be configured as an axial fan.

[0056] Understandably, when the outdoor unit 100 of the air conditioner is placed in an outdoor environment, the panel 22 is usually arranged outwards (i.e., the side without obstruction or with fewer obstructions) to ensure the air outlet effect on the fan cavity 202 side. Therefore, when it is necessary to inspect or repair the equipment in the outdoor unit 100, the panel 22 can be removed from the housing 21, allowing operators to inspect or repair the equipment, especially the electrical control box 10, from the front of the outdoor unit 100, reducing the difficulty of inspecting and repairing the outdoor unit 100.

[0057] It should be noted that in the relevant technology, the outdoor unit 100 of the air conditioner is installed in a pigeon coop installation scenario, which makes the inspection or maintenance of the outdoor unit 100 quite difficult. Furthermore, when it is necessary to inspect or repair the electrical control box 10 in the outdoor unit 100, the electrical control box 10 is usually removed by disassembling the top cover of the casing. However, in the pigeon coop installation scenario, this operation is quite difficult.

[0058] In this application, the electrical control box 10 is arranged on the partition 30, and the electrical control box 10 is located on the side of the partition 30 adjacent to the panel 22. When the electrical control box 10 needs to be inspected or repaired, the panel 22 can be removed to expose the electrical control box 10, making it easy for operators to remove the electrical control box 10, thereby reducing the difficulty of disassembling and assembling the electrical control box 10 in the air conditioner outdoor unit 100.

[0059] It is understandable that when operators disassemble or install the electrical control box 10 from the top of the air conditioner outdoor unit 100, the assembly environment of the air conditioner outdoor unit 100 makes it inconvenient for operators to observe and operate. According to one embodiment of the air conditioner outdoor unit 100 of this application, the electrical control box 10 can be disassembled or installed from the front side (i.e., the side of panel 22) of the air conditioner outdoor unit 100, which makes it easier for operators to observe and operate.

[0060] like Figure 7 As shown, in some embodiments of this application, the partition 30 includes a first section 31 and a second section 32, the first section 31 and the second section 32 are arranged along a second direction, the first section 31 is located on the side of the second section 32 adjacent to the panel 22, and is used to install the electrical control box 10.

[0061] The first plate segment 31 and the second plate segment 32 are arranged sequentially along a second direction within the cavity to divide the cavity and form a compressor cavity 201 and a fan cavity 202 arranged along a first direction. The first plate segment 31 is located in front of the second plate segment 32 to provide an installation structure for the first plate segment 31, facilitating the installation and fixation of the electrical control box 10 onto the first plate segment 31. It should be noted that the installation and engagement method between the electrical control box 10 and the partition plate 30 is not specifically limited here; the electrical control box 10 and the partition plate 30 can be connected and fixed by snap-fit, connectors, or other means as long as they meet the requirements.

[0062] As shown in Figure 5 , the partition plate 30 extends from front to back, the extension direction of the first plate segment 31 can be arranged perpendicular to the panel 22, and the second plate segment 32 can be arranged obliquely away from the fan 51 side from the connection with the first plate segment 31 in the second direction, so as to increase the space on one side of the fan cavity 202, facilitating the arrangement of devices (such as heat exchanger 52, fan 51, etc.) in the fan cavity 202. At the same time, the arrangement of the first plate segment 31 arranged perpendicular to the panel 22 can fully expose the electric control box 10, facilitating the disassembly and assembly operation of the electric control box 10 by the operator.

[0063] In some embodiments of the present application, the ventilation hole 301 is arranged on the first plate segment 31, and when the electric control box 10 is connected and fixed with the first plate segment 31, the first air outlet 1012 and the second air outlet 1022 are arranged opposite to the ventilation hole 301, so that the air discharged through the box assembly 15 can directly flow to the side of the fan cavity 202, thereby improving the flow effect of the air in the compressor cavity 201 flowing to the side of the fan cavity 202 through the electric control box 10.

[0064] It can be understood that the air flow through the electric control box 10 is formed by the negative pressure generated on the side of the fan cavity 202, and by arranging the air outlet structure (i.e. the first air outlet 1012 and the second air outlet 1022) of the electric control box 10 adjacent to the ventilation hole 301, the flow effect of the air in the compressor cavity 201 flowing into the side of the fan cavity 202 through the electric control box 10 under the action of negative pressure can be further improved.

[0065] Referring to Figure 3 , the partition plate 30 is arranged in the shell assembly 20 along the vertical direction, so that the compressor cavity 201 and the fan cavity 202 formed by the partition plate 30 are arranged horizontally.

[0066] Combined with Figure 2 and Figure 3 , in some embodiments of the present application, the shell body 21 includes a first side plate 211, a second side plate 212 and a back plate 213, the first side plate 211 and the second side plate 212 are arranged opposite in the first direction, and the first side plate 211 and the second side plate 212 are respectively located on both sides of the partition plate 30 in the first direction, the back plate 213 is arranged opposite to the panel 22, and the back plate 213 is connected between the first side plate 211 and the second side plate 212, and the air inlet portion 203 is formed on at least one of the first side plate 211 and the back plate 213.

[0067] As shown in Figure 3 , the first side plate 211 is a plate structure defining the compressor cavity 201, when the air inlet portion 203 is formed on the first side plate 211, air can be supplied to the compressor cavity 201 through the side of the air conditioner outdoor unit 100; referring to Figure 2When the air inlet portion 203 is formed on the back plate 213, air can be supplied to the compressor cavity 201 through the rear portion of the air conditioner outdoor unit 100.

[0068] It should be noted that the first side plate 211 and the back plate 213 can be simultaneously provided with the air inlet portion 203 to increase the communication area between the compressor cavity 201 and the outside of the shell assembly 20 and improve the air inlet effect at the compressor cavity 201. In the shell assembly 20, a plurality of air inlet portions 203 for communicating the outside of the shell assembly 20 and the compressor cavity 201 can be provided to improve the air inlet effect at the compressor cavity 201 by increasing the number of air inlet portions 203, and the position of the air inlet portion 203 is not specifically limited herein.

[0069] In some other embodiments of the present application, the panel 22 is provided with the air inlet portion 203, so that the compressor cavity 201 can be air-inlet from the front portion of the shell assembly 20.

[0070] It can be understood that the air inlet portion 203 is used to communicate the compressor cavity 201 with the outside of the shell assembly 20, and the compressor cavity 201 is formed in cooperation with the shell assembly 20 by the partition plate 30. When the air inlet portion 203 for communicating the outside of the shell assembly 20 and the compressor cavity 201 is formed on the back plate 213, the connecting and cooperating position of the partition plate 30 and the back plate 213 can be arranged in the first direction and spaced apart from the first side plate 211, that is, the compressor cavity 201 is formed by the top plate 214, the bottom plate 215, the first side plate 211, the panel 22 and the back plate 213. When the air inlet portion 203 for communicating the outside of the shell assembly 20 and the compressor cavity 201 is only provided on the first side plate 211, the second plate segment 32 in the partition plate 30 can be connected between the first plate segment 31 and the first side plate 211, so that the compressor cavity 201 is formed by the top plate 214, the bottom plate 215, the first side plate 211 and the panel 22.

[0071] It should be noted that the specific extension direction of the second plate segment 32 in the partition plate 30 and the connecting and cooperating position with the shell body 21 are not specifically limited herein, as long as the compressor cavity 201 and the fan cavity 202 can be formed by separating the cavities by the partition plate 30. For example, the shell body 21 is provided with a connecting flange extending to the side of the panel 22 on the side surface opposite to the back plate 213 and the panel 22, and the connecting and fixing of the partition plate 30 and the shell body 21 is achieved by connecting and cooperating the second plate segment 32 and the connecting flange, while the compressor cavity 201 is formed by being separated.

[0072] As Figure 4As shown, in some embodiments of the present application, the panel 22 comprises a first panel 221 and a second panel 222, which are arranged in sequence along the first direction and connected. Wherein, the abutting portion of the first panel 221 and the second panel 222 is connected and matched with the first plate segment 31 of the partition plate 30, that is, the first panel 221 is the component of the panel 22 corresponding to the fan cavity 202, and the second panel 222 is the component of the panel 22 corresponding to the compressor cavity 201, thereby facilitating the assembly of the shell assembly 20 and the partition plate 30, and facilitating the detection and maintenance of the devices in the fan cavity 202 and the compressor cavity 201.

[0073] It can be understood that when the electric control box 10 needs to be disassembled, only the second panel 222 needs to be disassembled from the shell body 21, so that the compressor cavity 201 is opened on one side of the panel 22, and the electric control box 10 can be disassembled and assembled from the side of the panel 22 by the operator. Similarly, if the devices (such as the fan 51, the heat exchanger 52, etc.) in the fan cavity 202 need to be detected and maintained, the first panel 221 can be disassembled, and the devices in the fan cavity 202 can be fully exposed from one side of the panel 22, thereby facilitating the operation of the operator.

[0074] In combination with Figure 4 and Figure 5 As shown, in some embodiments of the present application, the air inlet portion 203 is arranged spaced apart from the air inlet of the electric control box 10, and the minimum distance between the air inlet portion 203 and the air inlet of the electric control box 10 is L1, and satisfies the relationship: L1≥20mm. Therefore, the air outside the shell assembly 20 can enter the compressor cavity 201 through the air inlet portion 203, and further flow to the air inlet (i.e. the first air inlet 1011 and the second air inlet 1021) of the electric control box 10.

[0075] In some embodiments of the present application, the air inlet portion 203 is configured as an air inlet grille, which can allow the air outside the shell assembly 20 to enter, and can shield rainwater and other pollutants, so as to prevent rainwater and other pollutants from entering the compressor cavity 201 through the air inlet grille, thereby protecting the devices in the compressor cavity 201.

[0076] In combination with Figure 8 and Figure 9 As shown, in some embodiments of the present application, the electric control assembly 1 comprises a first device 11, a second device 12 and a PCB board 13. Wherein, the first device 11 is arranged on the first area 131 of the PCB board 13, the first air duct 101 covers at least part of the first area 131, and at least part of the first device 11 is arranged in the first air duct 101, the second device 12 is arranged on the second area 132 of the PCB board 13, the second air duct 102 covers at least part of the second area 132, and at least part of the second device 12 is arranged in the second air duct 102.

[0077] When air flows through the first air duct 101, it carries away the heat from the first device 11, achieving heat dissipation and cooling. When air flows through the second air duct 102, it carries away the heat from the second device 12, achieving heat dissipation and cooling. Therefore, thermal management of the devices in the electronic control assembly 1 can be partitioned, and their placement on the PCB board 13 can be designed according to their heat dissipation requirements to improve the heat dissipation and cooling effect at the electronic control box 10.

[0078] Further integration Figure 4 and Figure 9 As shown, when the control box 10 is installed on the partition plate 30, the PCB board 13 is arranged vertically, and the first area 131 and the second area 132 are also arranged vertically. The vertical arrangement increases the difficulty for rainwater, dust and other pollutants to adhere to the control components 1, thus protecting the devices in the control box 10.

[0079] like Figure 10 As shown, in some embodiments of this application, the first device 11 includes a heat sink 111 and a power device 112. The heat sink 111 is disposed on the PCB board 13 and arranged in the first air duct 101. When the air in the first air duct 101 flows through the heat sink 111, it can carry away the heat at the heat sink 111 to achieve heat dissipation and cooling at the heat sink 111.

[0080] Reference Figure 10 The power device 112 is also mounted on the PCB board 13, and the power device 112 can exchange heat with the heat sink 111 to transfer the heat of the power device 112 to the outside through the heat sink 111. Specifically, the power device 112 can transfer heat to one side of the heat sink 111, and exchange heat with the air flowing through the first air duct 101 through the heat sink 111, transferring the heat to the outside of the electrical control box 10, so as to achieve heat dissipation and cooling at the power device 112.

[0081] Furthermore, the power device 112 is a device that generates a lot of heat during the operation of the control box 10. By setting a heat sink 111 corresponding to the power device 112, the heat dissipation efficiency at the power device 112 can be guaranteed. At the same time, the aforementioned "power device 112" may include rectifier bridge, semiconductor power devices in PFC (Power Factor Correction) circuit, and inverter module, etc. The power device 112 is connected to the PCB board 13.

[0082] In some embodiments of the present application, the heat sink 111 comprises a heat dissipation substrate 1112 and a heat dissipation fin 1111, the heat dissipation substrate 1112 can be arranged in close contact with the power device 112 to exchange heat with the power device 112 through the heat dissipation substrate 1112, and the heat dissipation fin 1111 is arranged on the side of the heat dissipation substrate 1112 away from the power device 112, the heat dissipation area of the heat sink 111 is increased through the heat dissipation fin 1111, so that the heat dissipation efficiency of the electric control box 10 can be improved.

[0083] In some embodiments of the present application, the second device 12 comprises at least one of the inductive device 122 and the capacitive device 121. It can be understood that the second device 12 can comprise but is not limited to the inductive device 122 and the capacitive device 121 described above, and can also comprise other functional devices that generate less heat when the electric control box 10 is in an operating state, which is not limited here.

[0084] It should be noted that the first device 11 and the second device 12 in the electric control box 10 are arranged in two air duct structures respectively, that is, the air cooling and heat dissipation processes of the first device 11 and the second device 12 are relatively independent, so that the heat dissipation efficiency of the electric control box 10 on the first device 11 and the second device 12 can be improved.

[0085] In the related art, some electric control boxes 10 are cooled by air cooling, the devices in the electric control box 10 are arranged in the same heat dissipation air duct, so that the air in the electric control box 10 needs to flow through multiple devices in sequence, and the temperature of the air gradually increases on the air flow path, so that the heat exchange efficiency of the devices located in the downstream region of the air flow path is low, which affects the heat dissipation and cooling effect of the devices. At the same time, due to the electrostatic effect, dust is easily attached to the heat sink 111, and the dust is easily dropped and attached to other electrical devices under the action of air flow, so that the electrical devices are at risk of being punctured, affecting the safety of the electric control box 10.

[0086] In the present application, by classifying and arranging the devices in the electric control box 10 at the first region 131 and the second region 132 of the PCB board 13, arranging the first device 11 in the first air duct 101 and arranging the second device 12 in the second air duct 102, the shunt air cooling and heat dissipation can be realized in the electric control box 10, the safety and reliability of the electric control box 10 are improved while the heat dissipation efficiency is improved, and the dust is prevented from being attached to the electrical devices.

[0087] As Figure 10As shown, in some embodiments of the present application, the electric control box 10 further comprises a heat sink bracket 14, which is arranged on the PCB 13 and is used to mount the heat sink 111 to fix the heat sink 111 on the PCB 13 and is arranged in the first area 131, and the heat sink bracket 14 is adapted to be arranged around the power device 112 in the circumferential direction to shield the power device 112 in the circumferential direction, so as to prevent dust and other pollutants from adhering to the power device 112.

[0088] In some embodiments of the present application, the box assembly 15 comprises a surrounding plate structure 151 which is composed of a plurality of surrounding plates and through which the first air duct 101 and the second air duct 102 are defined and which is open to the side of the PCB, and the electric control assembly 1 can be mounted from the open side of the surrounding plate structure 151 so as to facilitate the arrangement of the PCB 13 parallel to the air supply direction and ensure the passing effect of air in the air duct structure.

[0089] In some embodiments of the present application, the box assembly 15 further comprises a mounting bracket 152 for mounting the electric control assembly 1, and the mounting bracket 152 is used to connect and cooperate with the surrounding plate structure 151, so as to fix the electric control assembly 1 on the box assembly 15 through the mounting bracket 152. In the assembly process of the electric control box 10, the electric control assembly 1 can be first mounted and cooperated with the mounting bracket 152, and then the mounting bracket 152 and the electric control assembly 1 are assembled together to the surrounding plate structure 151, so as to reduce the assembly difficulty of the electric control assembly 1. Wherein, the electric control assembly 1 and the mounting bracket 152 can be cooperated by clamping, and can also be connected and fixed by a connecting piece, which is not limited here.

[0090] In combination with Figure 4 , Figure 5 and Figure 8 As shown, in some embodiments of the present application, the PCB 13 is arranged parallel to the panel 22, so that the electric control box 10 is arranged regularly in the compressor cavity 201. When the electric control box 10 is arranged in the compressor cavity 201, the PCB 13 is arranged opposite and spaced apart from the panel 22.

[0091] Referring to Figure 5, the arrow is the air flow path in the cavity when the air conditioner outdoor unit 100 is in operation. Among them, the back plate 213 is provided with a ventilation structure communicating with the fan cavity 202, and the first side plate 211 is provided with an air inlet part 203. The air flow path at the air conditioner outdoor unit 100 includes two, one is that the air outside the shell assembly 20 enters the fan cavity 202 through the back plate 213, and is further transported to the side of the panel 22 under the action of the fan 51, and finally is discharged through the air outlet structure provided on the panel 22; the second is that the air outside the shell assembly 20 enters the compressor cavity 201 through the first side plate 211, the air in the compressor cavity 201 can flow to the ventilation hole 301 after flowing through the first air duct 101 and the second air duct 102 respectively, and the air flows into the fan cavity 202 through the ventilation hole 301, and is discharged from the panel 22 after mixing with the air in the fan cavity 202.

The air flow can form a negative pressure at the ventilation hole 301 of the partition plate 30 to suck the air on the side of the compressor cavity 201 into the fan cavity 202, drive the air in the compressor cavity 201 to flow, and cool the electric control box 10 by air cooling.

[0093] In some embodiments of the present application, the box assembly 15 and the panel 22 are spaced apart in the third direction, so that a gap can be reserved between the box assembly 15 and the panel 22 to avoid interference between the box assembly 15 and the panel 22.

[0094] In further embodiments of the present application, the distance between the box assembly 15 and the panel 22 in the third direction is L2, and satisfies the relationship: 0mm < L2≤30mm. Preferably, the preferred size of L2 is in the range of 5mm-10mm.

[0095] In some embodiments of the present application, the partition plate 30 is provided with a louver 33 at the ventilation hole 301, which can play a shielding role at the ventilation hole 301 while ensuring the through effect, so as to prevent the water, dust and other pollutants on the side of the fan cavity 202 from entering the compressor cavity 201 through the ventilation hole 301, reduce the risk of pollutants on the side of the fan cavity 202 entering the electric control box 10, and improve the reliability of the electric control box 10 during operation.

The application sets the shutter 33 to the side of the fan cavity 202 at the vent hole 301
