[0054] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0055] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0056] It should be noted that if the embodiments of this application involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0057] Furthermore, if the embodiments of this application involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated.

Additionally, the use of "and / or" or "and / or" throughout the text includes three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution that simultaneously satisfies A and B. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed in this application.

[0058] An air conditioner, also known as an air conditioning unit, is a device that regulates parameters such as temperature, humidity, airflow speed, and cleanliness within a closed space. An air conditioner generally consists of an outdoor unit and an indoor unit. Air cooling is one method of heat dissipation for the electronic control components in the outdoor unit. The air cooling system refers to the heat exchange between the electronic control components and air convection. Its modular design allows for complete disassembly and maintenance of the electronic control components, significantly improving after-sales service convenience.

[0059] However, in existing outdoor unit air-cooling systems, the heat sinks are typically positioned facing inwards, relying on the high-temperature air heated by the heat exchanger for heat dissipation. When the ambient temperature rises in summer, the surface temperature of the heat exchanger becomes very high, leading to a significant increase in the internal circulating air temperature of the outdoor unit. This greatly reduces the heat exchange efficiency of the heat sinks, resulting in low heat dissipation efficiency of the electronic control components. Secondly, when the air conditioner is used in a relatively humid environment, air-cooling systems are prone to condensation on the electronic control components or their wiring. Furthermore, since the outdoor unit is placed outdoors, water can easily enter the mounting cavity of the electronic control components.

[0060] Based on this, this application proposes a heat exchange module, which includes an electronic control component, aiming to improve the heat dissipation efficiency of the electronic control component, reduce the space occupied by the electronic control component in the outdoor unit, reduce the risk of condensation on the electronic control component, or improve the waterproof performance of the electronic control component.

[0061] Furthermore, it should be noted that the heat exchange module proposed in this application can be applied to air conditioners. When applied to an air conditioner, the heat exchange module can exchange heat with the external space to work in conjunction with other components of the air conditioner to treat the air in the target space of the air conditioner. This air treatment includes, but is not limited to, cooling, heating, dehumidification, or humidification. In addition, the heat exchange module proposed in this application can also be applied to other heat pump systems or heat pump devices, such as heat pump dishwashers, heat pump dryers, or heat pump water heaters, etc., which will not be listed here. In this case, the heat exchange module serves as the outdoor unit of other heat pump systems or heat pump devices, working in conjunction with other components of other heat pump systems or heat pump devices to complete their preset functions. The following will describe the application of the heat exchange module to an air conditioner as an example. When the heat exchange module is typically applied to an air conditioner, the outdoor unit is usually called the air conditioner outdoor unit.

[0062] The air conditioner can be a single unit, such as a portable or window-type air conditioner, or a split unit, such as a wall-mounted or floor-standing air conditioner. Furthermore, based on pipe type, air conditioners can be two-pipe, three-pipe, or four-pipe systems. A two-pipe air conditioner typically includes a cold pipe and a hot pipe, which can be shared, but can only operate in either cooling or heating mode at a time. In some scenarios, a two-pipe air conditioner may only be able to cool or only heat. A three-pipe air conditioner includes a cold pipe, a hot pipe, and a return pipe. Through valve control, different terminals (such as indoor units) can be selected for cooling or heating respectively, or a single indoor unit can be used for both cooling and heating simultaneously (in this case, there are two heat exchangers in one indoor unit, one for cooling and the other for heating). In this way, dehumidification without cooling can be achieved, for example, in the plum rain season in February and March in South China. Four-pipe air conditioners usually include completely independent cold and hot pipes and dual return water pipes. Their function is similar to that of three-pipe air conditioners. Four-pipe air conditioners have completely independent cold and hot circulation loops with no energy loss, but they are more expensive.

[0063] For ease of explanation, the following embodiments use a split-type air conditioner according to one embodiment of this application, combined with... Figures 1 to 16 The following example will be used for illustration. To facilitate understanding of the drawings, the specifications of this application are attached. Figures 1 to 16 In Chinese, a leader line with a solid arrowhead usually indicates a space, cavity, opening, or hole.

[0064] An air conditioner typically includes an outdoor unit 1 and an indoor unit, which are connected by refrigerant pipes. In this embodiment, the outdoor unit 1 and the indoor unit are separate units. The outdoor unit 1 usually includes a housing 100, a compressor 20, a fan 710, a heat exchanger 720, and an electrical control assembly 200. The housing 100, fan 710, heat exchanger 720, and electrical control assembly 200 can constitute a heat exchange module 10. The number of heat exchange modules 10 in one outdoor unit 1 can be one or more, for example, two, three, four, or six. Taking four heat exchange modules 10 as an example, each heat exchange module 10 can be independently equipped with a compressor 20, or any two or any three heat exchange modules 10 can share a single compressor 20. The compressor 20 is usually located inside the housing 100 and is connected to the heat exchanger 720 via refrigerant pipes.

[0065] The compressor 20 is the core component of the outdoor unit 1. The compressor 20 is a power device that uses mechanical energy to do work on gas, converting the low-pressure heat exchange medium it draws in into a high-pressure heat exchange medium, thereby driving the refrigerant to circulate in the system. Depending on different working principles and structural designs, the compressor 20 can be classified into various types, such as scroll compressors, reciprocating compressors, screw compressors, and rotary compressors. In this application, the compressor 20 can be a scroll compressor, a reciprocating compressor, or a screw compressor, etc., and this application does not limit its application in this regard.

[0066] Heat exchanger 720 refers to the heat exchanger of outdoor unit 1. It can function as either a condenser or an evaporator, depending on the air conditioner's operating mode. Air conditioner operating modes typically include cooling mode and heating mode. When the air conditioner is operating in cooling mode, heat exchanger 720 acts as a condenser; when the air conditioner is operating in heating mode, heat exchanger 720 acts as an evaporator. Taking the air conditioner operating in cooling mode as an example, heat exchanger 720 is responsible for cooling the high-temperature, high-pressure refrigerant gas discharged from compressor 20 into a liquid, releasing heat into the environment. Heat exchanger 720 is typically composed of many small pipes and aluminum heat sinks to increase the heat dissipation area and improve heat dissipation efficiency.

[0067] The fan 710 can be an axial fan 710 or a centrifugal fan 710; preferably, the embodiment of this application uses an axial fan 710, the air inlet side of the fan 710 is connected to the main air inlet, and the air outlet side of the fan 710 is connected to the main air outlet 101a; taking the heat exchanger 720 as a condenser as an example, when the fan 710 is working, it draws air from the external environment of the air conditioner, and through the condenser, helps to expel the hot air, thereby accelerating the heat dissipation process of the condenser.

[0068] The outer casing 100 forms the structural frame of the outdoor unit 1. The interior of the outer casing 100 has a accommodating space, providing structural installation space and installation position for the compressor 20, fan 710, heat exchanger 720 and electrical control components 200, etc. It also provides air ducts through the main air inlet and main air outlet 101a on the outer casing 100 that are connected to its accommodating space, thereby improving the heat exchange efficiency of the heat exchanger 720. In one embodiment, the outer casing 100 has opposing first sidewalls 101 and second sidewalls 102. The first sidewalls 101 and 102 can be any two opposing walls. Taking a box-shaped outer casing 100 as an example, the first sidewalls 101 and 102 can be a front wall and a rear wall, or a top wall and a bottom wall, etc. Generally, the outer casing 100 also includes a third sidewall connecting the first sidewalls 101 and 102. The first sidewalls 101, 102, and third sidewalls enclose a receiving cavity. The third sidewall can be a straight wall, a curved wall, or a bent wall, and can be a partially bent or folded wall. It is understood that the components constituting the first sidewall 101, second sidewall 102, and third sidewall can be either integrally formed by two of them or independently formed by all three. The following description will use the first sidewall 101 as the top wall and the second sidewall 102 as the bottom wall as an example.

[0069] In one example, the outer casing 100 includes a top cover 110, a chassis 120, and a connecting housing 130. The top cover 110 and the chassis 120 are disposed opposite each other, and the connecting housing 130 is connected between the chassis 120 and the top cover 110. The top cover 110 constitutes at least a portion of the first side wall 101, which can also be referred to as the top wall. The chassis 120 constitutes at least a portion of the second side wall 102, which can also be referred to as the bottom wall. That is, the second side wall 102 is at least a portion of the chassis 120. The connecting housing 130 constitutes at least a portion of the third side wall. In other words, the third side wall can be entirely composed of the connecting housing 130, or it can be partially composed of the connecting housing 130 and partially composed of the chassis 120 or the top cover 110. The chassis 120, the top cover 110, and the connecting housing 130 together enclose a receiving space.

[0070] The chassis 120 is the base of the outdoor unit 1. It is usually responsible for supporting the other components of the entire outdoor unit 1 and connecting to the ground, wall or other mounting carrier. The chassis 120 is usually designed with mounting holes and fixing points to facilitate the installation of the outdoor unit 1 on the mounting carrier. The chassis 120 can be plate-shaped or a hollow structure with an opening on one side.

[0071] The top cover 110 is the top covering component of the housing 100, and the main air outlet 101a is typically located on the top cover 110. In some embodiments, the fan 710 may be mounted on the top cover 110. In one example, taking an axial flow fan 710 as an example, the fan 710 includes a motor, a fan wheel 711 driven by the motor, and a guide ring 712. Generally, the guide ring 712 is mounted on the top cover 110, and the motor and fan wheel 711 are located inside the guide ring 712. Of course, in another example, the guide ring 712 may be located in other positions, for example, the guide ring 712 may be located on the connecting housing 130, etc.

[0072] The connecting housing 130 is a major part of the periphery of the outer casing 100. The connecting housing 130 is connected to the top cover 110, and the main air inlet is located on the connecting housing 130. In this application, the connecting housing 130 can be integrally formed or separately arranged, for example, formed by connecting multiple side plates. Generally, the connecting housing 130 usually extends along the direction from the top cover 110 to the chassis 120. In embodiments with multiple connecting housings 130, the multiple connecting housings 130 are arranged sequentially in one direction to form a ring, near-ring, or semi-ring structure. Adjacent connecting housings 130 can be detachably connected or fixedly connected; no specific limitation is made here. In one example, the connecting housing 130 is configured as an air inlet grille, and the heat exchanger 720 is mounted on the air inlet grille, thereby increasing the area of ​​the main air inlet, increasing other usable internal space of the outer casing 100, and improving the heat dissipation effect of the heat exchanger 720 and the compressor 20. Of course, in other embodiments of this application, the heat exchanger 720 can also be mounted on other components.

[0073] The electronic control component 200 is the control unit of the outdoor unit 1. It integrates various circuit boards 210, sensors, and protection components, and is responsible for coordinating, monitoring, and protecting the operation of the outdoor unit. It also coordinates with the control device of the indoor unit to achieve intelligent adjustment of the air conditioner. The electronic control component 200 includes a circuit board 210, which has two opposing sides along its thickness direction, one of which faces the first wall. The circuit board 210 typically includes a PCB (Printed Circuit Board) and electronic components mounted on the PCB. The PCB is usually thin, meaning it has two sides along its thickness direction. In this application, the two sides along the thickness direction of the PCB are referred to as the two sides of the circuit board 210.

[0074] The circuit board 210 includes a control unit 211, also known as a motherboard or main control board. The control unit 211 is responsible for receiving sensor signals, processing data, and controlling the operating status of outdoor unit components such as compressor 20 and fan 710. The control unit 211 usually also has protection functions, such as overload and over-temperature protection.

[0075] Circuit board 210 includes a power drive unit 212, which is responsible for converting the input AC power into DC power, or providing a stable low-voltage DC power supply to the control unit 211 or other circuit boards 210. The power drive unit 212 includes rectification, filtering, and voltage regulation circuits, thereby providing a safe and reliable power supply for the control circuit, drive circuit, and sensors. The power drive unit 212 is also responsible for driving and controlling the operating state of the compressor 20, realizing speed regulation, controlling the refrigerant circulation volume and system energy efficiency ratio. For example, in a variable frequency air conditioner, this module adjusts the compressor 20 speed according to the instructions of the control unit 211. In addition, the power drive unit 212 is also responsible for driving the fan 710 of the outdoor unit 1, adjusting the fan speed as needed, supporting variable frequency control, and maintaining efficient and energy-saving operation. The power drive unit 212 is usually also equipped with fault detection and protection mechanisms, such as overload protection and phase loss protection. In the outdoor unit 1, the control unit 211 and the power drive unit 212 can be integrated into one circuit board 210, or they can be divided into multiple circuit boards 210, such as two circuit boards 210 or three circuit boards 210, etc., without specific limitations here.

[0076] The installation space can be divided within the outer casing 100 using partitions or similar components. Alternatively, the electrical control component 200 can be installed in a separate housing; specific limitations are not specified here. In embodiments where the electrical control component 200 is installed in a separate housing, and the housing is then mounted onto the outer casing 100 of the outdoor unit 1, the housing has an installation space and is typically made of metal (such as galvanized steel or cold-rolled steel) or high-strength engineering plastic. The housing is mounted onto the outer casing 100, and the connection between the housing and the outer casing 100 can be achieved through one or more of the following methods: plug-in, snap-fit, pin-fit, tenon-and-mortise, or fastener connection. Fasteners can be threaded connectors or cable ties, etc. The housing and the outer casing 100 can also be connected by welding or other fixing methods. To facilitate after-sales maintenance and ensure structural stability, the housing and the outer casing 100 are primarily connected via threaded connectors.

[0077] The electronic control component 200 includes a heat sink 220, which is a heat dissipation device. The heat sink 220 increases the contact area with air, quickly removing heat generated by the circuit board 210 and preventing overheating. In the power drive unit 212 of the outdoor unit 1, because the power drive unit 212 needs to withstand high voltage and high current and operates in a high-frequency switching state, it generates a large amount of heat. The main function of the heat sink 220 is to effectively dissipate this heat, preventing the electronic control component 200 from being affected by excessive temperature, thus extending its performance and lifespan, or even damaging the device. In this embodiment, the heat sink 220 is typically composed of multiple thin heat sink fins, which increase the contact area with air. For example, the heat sink 220 is a finned heat sink 220. The heat sink 220 mainly utilizes convection heat transfer for heat dissipation. Convection heat transfer typically includes natural convection and forced convection. Natural convection refers to the flow of air caused by temperature differences, while forced convection accelerates airflow through external devices such as fans.

[0078] Taking the division of the housing 100 into a first housing cavity 14 and a second housing cavity 15 by the separator 600 as an example, the fan 710 and heat exchanger 720 are disposed in the first housing cavity 14, and the circuit board 210 and heat sink 220 are disposed in the second housing cavity 15. The second housing cavity 15 is provided with a heat dissipation air duct, which has a heat dissipation air inlet and a heat dissipation air outlet. The heat dissipation air inlet is connected to the external space, and the heat dissipation air outlet is connected to the first housing cavity 14 and the second housing cavity 15. Thus, when the fan 710 is working, the operation of the fan 710 forms a positive pressure zone and a negative pressure zone. Generally speaking, the positive pressure zone can be understood as the air outlet side of the fan 710, and the negative pressure zone can be understood as the air inlet side of the fan 710. In one example, the outlet end of the air guide ring 712 of the fan 710 is directly connected to the first side wall 101, that is, connected to the top cover 110, so that the entire housing space of the housing 100 is a negative pressure zone. In this application, the heat dissipation outlet is located on the air inlet side of the fan 710, that is, the heat dissipation outlet is located in the negative pressure zone of the fan 710. This allows airflow to be driven from the heat dissipation inlet into the second receiving cavity 15 and exchange heat with the circuit board 210 or the heat sink 220. The airflow after heat exchange flows out from the heat dissipation outlet into the receiving space, and finally flows out from the main outlet 101a to the external space, thereby dissipating heat from the electronic control component 200. Thus, this application improves the heat dissipation efficiency of the electronic control component 200 by directly passing external airflow through the second receiving cavity 15 to dissipate heat from the electronic control component 200 or the heat sink 220, then through the first receiving cavity 14, and finally out from the main outlet 101a, compared with the prior art which uses high-temperature air heated by the heat exchanger 720 to exchange heat with the heat sink 220.

[0079] Since the radiator 220 is installed in the second receiving cavity 15, it will increase the volume of the second receiving cavity 15, which will lead to the problem that the electronic control component 200 occupies too much space in the outdoor unit 1 or the heat exchange module 10.

[0080] Therefore, in order to reduce the space occupied by the electronic control component 200 in the heat exchange module 10, in one embodiment, please refer to... Figures 1 to 4 , Figure 15 The heat exchange module 10 includes a housing 100, a partition 600, a heat exchange assembly 700, and an electrical control assembly 200. The housing 100 has a first sidewall 101 and a second sidewall 102 facing each other. The direction from the first sidewall 101 to the second sidewall 102 is a first direction. The first sidewall 101 is provided with a main air outlet 101a. The partition 600 is disposed inside the housing 100, and a first receiving cavity 14 and a second receiving cavity 15 extending at least partially along the first direction are formed between the partition 600 and the housing 100. The main air outlet 101a and the first receiving cavity... The first cavity 14 is connected, and the portion of the second receiving cavity 15 near the second sidewall 102 protrudes into the first receiving cavity 14 to form a receiving space 15a; the heat exchange assembly 700 includes a heat exchanger 720 and a fan 710, the heat exchanger 720 is disposed in the first receiving cavity 14, and the fan 710 is located on the side of the first receiving cavity 14 near the first sidewall 101; the electrical control assembly 200 includes a circuit board 210 and a heat sink 220 connected to the circuit board 210, the circuit board 210 is electrically connected to the fan 710, the electrical control assembly 200 is disposed in the second receiving cavity 15, and the heat sink 220 is located in the receiving space 15a.

[0081] The outer casing 100 has a first sidewall 101 and a second sidewall 102. As described above, the first sidewall 101 and the second sidewall 102 can be any two opposing walls. Taking the outer casing 100 as a box shape, the first sidewall 101 and the second sidewall 102 can be the front wall and the rear wall, or the top wall and the bottom wall, etc. Here, for ease of explanation, the direction from the first sidewall 101 to the second sidewall 102 is defined as the first direction. For example, taking the first sidewall 101 as the top wall and the second sidewall 102 as the bottom wall, when the air conditioner is placed horizontally, that is, when the second sidewall 102 is placed on a horizontal platform, the first direction can be understood as the vertically downward direction. In this embodiment, the first direction can be the vertically downward direction, or it can be understood as the angle between the first direction and the vertically downward direction being very small. For example, the angle can be 1°, 2°, 3°, 4°, 5°, 6°, 7°, 8°, 9° or 10°, etc.

[0082] The fan 710 is located at one end of the first receiving cavity 14 near the first side wall 101. The fan 710 can be installed on the component constituting the first side wall 101 or on other components, and is located at one end of the first receiving cavity 14 near the first side wall 101. Since the main air outlet 101a is located on the first side wall 101, placing the fan 710 at one end of the first receiving cavity 14 near the first side wall 101 can increase the coverage area of ​​the negative pressure zone of the fan 710. For example, when the fan 710 is an axial flow fan 710, when the air outlet end of its air guide ring 712 is connected to the first side wall 101, the entire internal space of the outer casing 100 is a negative pressure zone.

[0083] The partition 600 is a structural component disposed inside the housing 100 to divide the space within the housing 100 into at least two independent accommodating cavities (a first accommodating cavity 14 and a second accommodating cavity 15). The partition 600 may be plate-shaped, a hollow structure with an opening on one side, or other geometric shapes. It extends at least partially along a first direction and, together with the inner wall of the housing 100, forms two or more independent spatial regions. The first accommodating cavity 14 is a spatial region enclosed by the partition 600 and the inner wall of the housing 100, extending at least partially along the first direction; that is, the length direction of the first accommodating cavity 14 is not limited to extending along the first direction. The second accommodating cavity 15 is an adjacent but independent spatial region of the first accommodating cavity 14, also enclosed by the partition 600 and the inner wall of the housing 100. The first accommodating cavity 14 and the second accommodating cavity 15 are located between the first sidewall 101 and the second sidewall 102. Both the first accommodating cavity 14 and the second accommodating cavity 15 extend at least partially along the first direction; that is, they may extend partially or entirely along the first direction.

[0084] For example, for ease of understanding and explanation, the outer casing 100 includes a top cover 110, a chassis 120, and a connecting housing 130, with the top cover 110 and chassis 120 disposed opposite to each other, and the connecting housing 130 connected between chassis 120 and top cover 110. The top cover 110 forms a first sidewall 101, and chassis 120 forms a second sidewall 102. The partition 600 has opposing first and second sides, with a first receiving cavity 14 located on the first side of the partition 600 and a second receiving cavity 15 located on the second side of the partition 600. The partition 600 has opposing first and second ends, wherein the first end of the partition 600... One end of the partition 600 can be connected to the top cover 110 or to the portion of the connecting housing 130 near the first sidewall 101; the second end of the partition 600 can be connected to the chassis 120 or to the portion of the connecting housing 130 near the second sidewall 102, etc.; the first receiving cavity 14 and the second receiving cavity 15 are located between the first sidewall 101 and the second sidewall 102, and both the first receiving cavity 14 and the second receiving cavity 15 can extend at least partially along the first direction; that is, the first end of the partition 600 may not be connected to the top cover 110, and the second end of the partition 600 may not be connected to the chassis 120. The portion of the second receiving cavity 15 near the second sidewall 102 protrudes toward the first receiving cavity 14 to form a receiving space 15a for placing the radiator 220. This can be understood as the portion of the partition 600 near the second sidewall 102 protruding from the second side toward the first side to form a receiving space.

[0085] In this embodiment, the technical solution involves providing a partition 600 inside the outer casing 100 to divide the internal space of the outer casing 100 into a first receiving cavity 14 and a second receiving cavity 15. The fan 710 is located on the side of the first receiving cavity 14 near the first side wall 101, and the portion of the second receiving cavity 15 near the second side wall 102 protrudes toward the first receiving cavity 14 to form a receiving space 15a for the installation of the radiator 220. That is, the radiator 220 is located at the end of the second receiving cavity 15 away from the fan 710, which will not affect the installation space of the fan 710. In this way, the heat dissipation efficiency can be effectively improved without increasing the volume of the heat exchange device.

[0086] In some embodiments, please refer to Figure 2 And further reading Figure 4 , Figure 7 and Figure 8The separator 600 includes a separator plate 610 and a mounting shell 620. The separator plate 610 extends along a first direction and has opposing first and second sides. A first receiving cavity 14 is formed between the first side of the separator plate 610 and the outer shell 100. The separator plate 610 is provided with a mounting opening 610a that passes through the first and second sides. The mounting shell 620 is located at the mounting opening 610a. At least a portion of the mounting shell 620 is located within the first receiving cavity 14. At least a portion of the second receiving cavity 15 is formed between the mounting shell 620 and the outer shell 100. One end of the mounting shell 620 near the second sidewall 102 protrudes from the first receiving cavity 14.

[0087] The separator 600 consists of a separator plate 610 and a mounting shell 620. The separator plate 610 extends along a first direction and has a first side and a second side, that is, the separator plate 610 has two opposite sides, which can be understood as a first side and a second side. The first side of the separator plate 610 forms a first receiving cavity 14 between itself and the outer shell 100. In this embodiment, the second side of the separator plate 610 can be spaced apart from the connecting shell 130 to form a partial second receiving cavity 15. Another part of the second receiving cavity 15 is formed between the mounting shell 620 and the connecting shell 130. The second side of the separator plate 610 can also be directly attached to a part of the sidewall formed by the connecting shell 130. The second receiving cavity 15 is formed by the mounting shell 620 and the connecting shell 130.

[0088] The mounting shell 620 is disposed at the mounting opening 610a, and at least a portion of the second receiving cavity 15 is formed between the mounting shell 620 and the outer shell 100. The mounting shell 620 may be partially located inside the first receiving cavity 14 and partially located outside the first receiving cavity 14, or it may be entirely located in the first receiving cavity 14. The second receiving cavity 15 may be entirely composed of the mounting shell 620 and the outer shell 100, or the mounting shell 620 and the outer shell 100 may constitute a portion of the second receiving cavity 15, and the second side of the partition plate 610 and the outer shell 100 may constitute another portion of the second receiving cavity 15.

[0089] In this embodiment, at least a portion of the mounting shell 620 is disposed within the first receiving cavity 14, and at least a portion of the second receiving cavity 15 is formed between the mounting shell 620 and the outer shell 100, such that the portion of the second receiving cavity 15 near the second side wall 102 can extend toward the first receiving cavity 14, significantly improving space utilization without increasing the overall volume of the heat exchange module 10; secondly, the partition 600 is set in two parts, with the partition plate 610 serving as the basic frame to provide the main support, which can be made of metal to strengthen the structural strength at this point, and the mounting shell 620 serving as the mounting structure of the functional module, which can be made of engineering plastic to achieve lightweighting.

[0090] In some embodiments, please refer to Figure 2And further reading Figure 4 , Figure 7 and Figure 8 The portion of the mounting housing 620 located in the first receiving cavity 14 has a first wall, which extends along a first direction. The first wall defines a receiving space 15a between the first wall and the housing 100. The distance between the first wall and the partition plate 610 increases along the first direction.

[0091] The first wall refers to a portion of the wall that defines the accommodating space 15a. The first wall is arranged along a first direction. In other words, the first wall has a first end and a second end. The first end refers to the end of the first wall that is close to the first side wall 101, and the second end refers to the end of the first wall that is close to the second side wall 102. The length direction of the first wall from the first end to the second end is the same as or similar to the direction along the first side wall 101 to the second side wall 102. For example, when the air conditioner is placed horizontally, that is, when the chassis 120 is placed on the mounting surface, the first direction can be understood as the vertically downward direction. In this embodiment, the first direction can be the vertically downward direction, or it can be understood as the angle between the first direction and the vertically downward direction being very small. For example, the angle can be 1°, 2°, 3°, 4°, 5°, 6°, 7°, 8°, 9° or 10°, etc.

[0092] The distance between the first wall and the partition plate 610 increases along the first direction. In this embodiment, in order to reduce the space occupied by the electronic control component 200 in the outdoor unit of the air conditioner, the distance between the first wall and the partition plate 610 can be gradually increased. That is, the first wall is inclined and extended towards the second side wall 102. It can be increased in a step-like manner, or it can be increased rapidly first, then slowly, and finally further slowly, etc.

[0093] In some embodiments, please refer to Figure 2 And further reading Figure 4 , Figure 7 and Figure 8 The first wall extends at an angle toward the second side wall 102.

[0094] The first wall extends at an angle toward the second side wall 102, meaning that the space at the second end is larger than the space at the first end, allowing for a certain amount of space at the second end to be used for installing the radiator 220. The fan 710 is located at the first end close to the first wall, and the radiator 220 is located at the second end of the first wall, that is, the end away from the fan 710, so as not to affect the installation space of the fan 710. In this way, the heat dissipation efficiency of the electrical control component 200 of the air conditioner outdoor unit is improved or the space occupied by the electrical control component 200 of the air conditioner outdoor unit is reduced.

[0095] In this embodiment, the first wall constituting the accommodating space 15a extends at an angle, which can more effectively disperse the pressure of the airflow, reduce resistance, and reduce turbulence or eddies at the first air outlet 12. The angled extension design can disperse external forces (such as wind pressure and impact force) along the slope, reduce local stress concentration, and thus enhance the structural stability of the mounting shell 620. In addition, rainwater can slide off naturally on the angled surface, reducing the amount of rainwater that stays on the first wall.

[0096] In some embodiments, please refer to Figure 2 And further reading Figure 4 , Figure 7 and Figure 8 The mounting housing 620 is provided with a mounting groove 620a, which has a groove opening and a first groove wall 621 opposite to the groove opening. The first groove wall 621 extends along a first direction and includes a first mounting section 621a and a second mounting section 621b. The circuit board 210 includes a control unit 211 and a power drive unit 212. The control unit 211 is mounted on the first mounting section 621a. The power drive unit 212 is mounted on the second mounting section 621b. The heat sink 220 is connected to the power drive unit 212. The first wall includes at least the second mounting section 621b.

[0097] The circuit board 210 is divided into a control section 211 and a power drive section 212. The control section 211 is mounted on the first mounting section 621a, and the power drive section 212 is mounted on the second mounting section 621b. This separate design facilitates modularization of functions, making maintenance and troubleshooting easier. The separate control section 211 and power drive section 212 clearly define the function of each module, allowing for individual replacement or repair as needed. This improves the maintainability, scalability, and fault diagnosis efficiency of the entire system, and facilitates after-sales maintenance. Preferably, the heat sink 220 is located at the end of the power drive section 212 furthest from the control section 211.

[0098] In the technical solution of this embodiment, the heat generated by the power drive unit 212 is much higher than that of the control unit 211. Therefore, a heat sink 220 is usually provided on the power drive unit 212. The power drive unit 212 is located in the second mounting section 621b, which is the end away from the fan 710. In this way, the heat dissipation efficiency can be effectively improved without increasing the volume of the heat exchange device.

[0099] In some embodiments, please refer to Figure 1 and 2 And further reading Figure 4 , Figure 7 and Figure 8The outer casing 100 includes a top cover 110, a chassis 120, and a connecting housing 130. The top cover 110 forms a first side wall 101, the chassis 120 forms a second side wall 102, and the connecting housing 130 is connected between the chassis 120 and the top cover 110. A partition 600 is installed in at least one of the top cover 110, the chassis 120, and the connecting housing 130. The partition 600 extends along a first direction and has a first air outlet 12 communicating with the second receiving cavity 15. The first air outlet 12 is located on the air inlet side of the fan 710. The connecting housing 130 has a first air inlet 11 communicating with the second receiving cavity 15.

[0100] The top cover 110, chassis 120, and connecting housing 130 together provide a robust structural framework for the internal components. The top cover 110 and chassis 120 form the two side walls of the housing 100, respectively, while the connecting housing 130 connects the top cover 110 and chassis 120, providing a robust and stable frame for the housing 100 that effectively protects the internal components from external impacts, dust, and other physical damage.

[0101] As described above, the partition 600 is used to divide the space inside the housing 100, effectively separating the spaces between different functional areas. The partition 600 is installed in at least one of the top cover 110, the chassis 120, and the connecting housing 130. That is, the partition 600 can be installed in the top cover 110, the chassis 120, and the connecting housing 130, or it can be installed in any two of these three locations. Alternatively, the partition 600 can be connected to all three locations, as long as it extends along the first direction. Preferably, the partition 600 is installed in at least two of the top cover 110, the chassis 120, and the connecting housing 130, thus improving the stability of the partition 600 installation.

[0102] The first air outlet 12 is located on the air inlet side of the fan 710, that is, the first air outlet is located in the negative pressure area of ​​the fan 710. It can drive the airflow from the first air outlet into the second receiving cavity 15 and exchange heat with the circuit board 210 or the heat sink 220. The airflow after heat exchange flows out from the heat dissipation air outlet into the receiving space, and finally flows out from the main air outlet 101a into the external space, thereby dissipating heat from the electronic control component 200.

[0103] The technical solution of this embodiment improves the heat dissipation efficiency of the electronic control component 200 by directly passing the external airflow through the second receiving cavity 15, dissipating heat with the electronic control component 200 or the radiator 220, then passing through the first receiving cavity 14, and finally flowing out from the main air outlet 101a. Compared with the prior art, which uses high-temperature air heated by the heat exchanger 720 to exchange heat with the radiator 220, the solution of this embodiment can improve the heat dissipation efficiency of the electronic control component 200.

[0104] In some embodiments, please refer to Figure 1 The plane perpendicular to the first direction is an auxiliary plane. In the cross-sectional shape of the connecting housing 130, the outline shape of the connecting housing 130 is usually a regular shape such as a circle, a square, or a rounded square. Of course, in other embodiments, it can be other regular or irregular shapes, which are not specifically limited here. Taking a near-rounded square as an example, the square is a square, and the four corners of the square are rounded to form a rounded square. In this application, the electronic control component 200 can be set at the corresponding rounded corner, which can further reduce the size of the heat exchange component 700.

[0105] To reduce the processing difficulty of the circuit board 210, the circuit board 210 has two opposing sides along its thickness side. The components and heat sink 220 on the circuit board 210 are located on one of these two sides, and the components and heat sink 220 on the circuit board 210 are located on the same side of the circuit board 210. In this way, compared to setting the components and heat sink 220 on both sides separately, only one side of the circuit board 210 needs to be set with the components and heat sink 220, which can reduce the processing difficulty of the circuit board 210.

[0106] In some embodiments, please refer to Figure 1 And further reading Figure 3 and Figure 7 The connecting housing 130 includes a surrounding plate 131 and a cover plate 132. The surrounding plate 131 is connected between the top cover 110 and the chassis 120. The surrounding plate 131 has a first opening 130a, and the cover plate 132 covers the first opening 130a. A partition 600 is provided at the first opening 130a. One side of the partition 600 and the surrounding plate 131 define a first receiving cavity 14, and the other side of the partition 600 and the cover plate 132 define a second receiving cavity 15. The cover plate 132 has a first air inlet 11.

[0107] In this embodiment, the connecting housing 130 is a separate unit, and the surrounding plate 131 is the main part of the connecting housing 130. The heat exchanger 720 is mounted on the surrounding plate 131, and the surrounding plate 131 has a first opening 130a. The first opening 130a can be an openwork extending from the top cover 110 to the chassis 120, such as... Figure 4 As shown, it can also be a partial opening. The cover plate 132 is provided with a first air inlet 11. The cover plate 132 is an independent structure. The first air inlet 11 is located on the cover plate 132, which facilitates processing.

[0108] The separator 600 is located at the first opening 130a. One side of the separator 600 and the surrounding plate 131 define a first receiving cavity 14, and the other side of the separator 600 and the cover plate 132 define a second receiving cavity 15. Thus, when the cover plate 132 is opened, the second receiving cavity 15 is opened, which facilitates after-sales maintenance of the electronic control component 200.

[0109] Based on the previous embodiment, please refer to Figures 1 to 3 And further reading Figure 7 The enclosure 131 includes a first side plate 131a, a second side plate 131b, and a support plate 131c. The first side plate 131a is connected between the top cover 110 and the chassis 120. The second side plate 131b is located on the chassis 120. The support plate 131c is located on the second side plate 131b and is located on the side of the second side plate 131b away from the first receiving cavity 14. The support plate 131c is opposite to and spaced apart from the second side wall 102. The first opening 130a is located between the support plate 131c and the top cover 110. The cover plate 132 is connected between the top cover 110 and the support plate 131c. The support plate 131c is provided with a first air inlet 11.

[0110] The enclosure 131 consists of a first side plate 131a, a second side plate 131b, and a support plate 131c. The first side plate 131a connects the top cover 110 and the chassis 120, and the second side plate 131b is located on the chassis 120. The enclosure 131 is a separate unit, reducing processing difficulty. In other embodiments, the second side plate 131b and the support plate 131c can be integrally formed.

[0111] The support plate 131c is located on the side of the second side plate 131b opposite to the first receiving cavity 14, and is spaced apart from the second side wall 102. Thus, the support plate 131c also forms a wall of the second receiving cavity 15; the cover plate 132 connects the top cover 110 and the support plate 131c, further sealing the first opening 130a to prevent external dust, moisture and other substances from entering the equipment, thereby protecting the safety of the internal components.

[0112] There are multiple first air inlets 11, some located on the support plate 131c and some on the cover plate 132. This design of multiple first air inlets 11 effectively increases airflow, aiding in heat dissipation within the equipment. The first air inlets 11 are located on both the support plate 131c and the cover plate 132, allowing air to flow in from multiple directions, improving the overall heat dissipation of the electrical control assembly 200. Furthermore, the design of multiple first air inlets 11 improves the uniformity of airflow, reducing localized overheating. Since the fan 710 is located near the top cover 110, the air inlets on the support plate 131c and the cover plate 132 can better distribute heat, improving heat dissipation efficiency and extending the service life of the electrical control assembly 200.

[0113] In this embodiment, the cover plate 132 and the support plate 131c are simultaneously provided with the first air inlet 11. Compared with single-sided air inlet, the air intake of the second receiving cavity 15 can be increased. Furthermore, since the first air inlet 11 is usually composed of multiple micro-hole arrays, the first air inlet 11 provided on the cover plate 132 can be washed by rainwater, which can reduce the blockage of the first air inlet 11.

[0114] In other embodiments, only the support plate 131c may have a first air inlet 11, or only the cover plate 132 may have a first air inlet 11.

[0115] In some embodiments, please refer to Figure 6 The cover plate 132 includes a first plate segment 132a and a second plate segment 132b. The length direction of the first plate segment 132a and the second plate segment 132b extends along a first direction. The width direction of the first plate segment 132a and the width direction of the second plate segment 132b extend along the circumference of the outer shell 100, respectively. The width direction of the first plate segment 132a and the width direction of the second plate segment 132b form an angle. The first plate segment 132a and the second plate segment 132b are respectively provided with a first air inlet 11.

[0116] In this embodiment, the first plate segment 132a and the second plate segment 132b are each provided with a first air inlet 11, providing multiple air intake channels, increasing the air intake volume, and improving the heat dissipation effect. In addition, the number of channels for air to flow into the second receiving cavity 15 is increased, improving air flow. This embodiment is based on the previous embodiment, in which the support plate 131c is also provided with a first air inlet 11. Thus, compared with single-sided air intake, the three-sided air intake in this embodiment can reduce airflow turbulence caused by excessively concentrated airflow direction, resulting in a stable airflow distribution.

[0117] In some embodiments, please refer to Figure 6 And further reading Figure 3 and Figure 7 The first air inlet 11 is located at one end of the first plate segment 132a near the second side wall 102; and / or, the first air inlet 11 is located at one end of the second plate segment 132b near the second side wall 102.

[0118] Specifically, the first air inlet 11 may be provided at one end of the first plate segment 132a near the support plate 131c, or the first air inlet 11 may be provided at one end of the second plate segment 132b near the support plate 131c; or, the first air inlet 11 may be provided at one end of the first plate segment 132a near the support plate 131c, and the first air inlet 11 may be provided at one end of the second plate segment 132b near the support plate 131c.

[0119] In this embodiment, the first air inlet 11 is located at one end of the first plate segment 132a and the second plate segment 132b near the support plate 131c, so that air enters the second accommodating cavity 15 from the end away from the main air outlet 101a. This can avoid air backflow with the top main air outlet 101a, and the hot air is quickly discharged after the bottom air inlet, thereby preventing the hot air from re-entering the second accommodating cavity 15.

[0120] In some embodiments, please refer to Figure 6 The cover plate 132 also includes a third plate segment 132c extending along the first direction, the third plate segment 132c being connected between the first plate segment 132a and the second plate segment 132b; the first plate segment 132a and the second plate segment 132b are straight plate segments, and the third plate segment 132c is an arc-shaped plate segment or the third plate segment 132c is a straight plate segment.

[0121] The first and second plate segments 132a and 132b, being straight segments, provide a simple and effective closure structure. The third plate segment 132c is designed to connect with the first and second plate segments 132a and 132b. The third plate segment 132c can be an arc-shaped segment or a straight segment. The arc-shaped segment design helps to create a curved transition in the structure, which not only enhances the aesthetics but also strengthens the structural strength of the cover plate 132, avoids stress concentration, and improves durability. If the third plate segment 132c is a straight segment, the manufacturing process can be simplified, costs reduced, and structural stability maintained.

[0122] In some embodiments, a second baffle plate 800 is provided in the second receiving cavity 15. The second baffle plate 800 is located at the portion of the cover plate 132 where the first air inlet 11 is provided and the separator 600. An air passage gap is provided between the second baffle plate 800 and the cover plate 132.

[0123] The second baffle plate 800 is typically a thin plate, and its edges are usually designed as connecting flanges for easy installation with the partition 600. These connecting flanges can be located on both sides of the outer casing 100 circumferentially, and are typically connected to the cover plate 132. An air passage gap is provided between the second baffle plate 800 and the cover plate 132. The second baffle plate 800 is designed to create a physical barrier between the air inlet area and the electrical control component 200, reducing the entry of moisture or other liquids into the central area of ​​the second receiving cavity 15 through the first air inlet 11, especially when the heat exchange module 10 is exposed to a humid environment or encounters water splashes. The air passage gap allows outside air to enter other areas of the second receiving cavity 15.

[0124] Furthermore, a second baffle plate 800 is disposed on the cover plate 132, and the end of the second baffle plate 800 away from the second side wall 102 is sealed to the cover plate 132 by a first sealing member 70.

[0125] The second baffle plate 800 is disposed on the cover plate 132. The relationship between the second baffle plate 800 and the cover plate 132 can be plugged in, snapped in, or connected by fasteners, or it can be welded or glued together. The first sealing element 70 can be sponge, foam, or rubber, etc., and no specific limitation is made here.

[0126] In this embodiment, the end of the second baffle plate 800 away from the second side wall 102 is sealed to the cover plate 132 by the first sealing member 70, which can prevent air from flowing out from the gap between the second baffle plate 800 and the cover plate 132 and into the central area of ​​the second receiving cavity 15, thereby improving the water blocking effect of the second baffle plate 800.

[0127] In some embodiments, please refer to Figures 8 to 11 The second baffle plate 800 includes a first baffle 810, a second baffle 820 and a third baffle 830; the first baffle 810 is opposite to and spaced apart from the first plate segment 132a, the second baffle 820 is opposite to and spaced apart from the second plate segment 132b, the third baffle 830 is opposite to and spaced apart from the third plate segment 132c, and the third baffle 830 is provided with an air outlet 831.

[0128] In this embodiment, the first baffle 810 is opposite to and spaced apart from the first plate segment 132a, the second baffle 820 is opposite to and spaced apart from the second plate segment 132b, and the third baffle 830 is opposite to and spaced apart from the third plate segment 132c, thus forming a wind passage gap.

[0129] The first section 132a and the second section 132b of the cover plate 132 are respectively provided with the first air inlet 11, forming the first air inlet area and the second air inlet area, effectively guiding air into the second accommodating cavity 15. At the same time, the third section 132c is connected between the first section 132a and the second section 132b, serving as a transition area. It not only plays a structural connection role, but also serves as an air outlet 831, allowing the air inlet of the second accommodating cavity 15 to be laterally air-intake.

[0130] The first baffle 810 and the second baffle 820 have no air passage 831, while the third baffle 830 has an air passage 831. The first plate segment 132a and the second plate segment 132b have a first air inlet 11, while the third plate segment 132c does not have a first air inlet 11. Thus, the air passage 831 on the second baffle 800 and the first air inlet 11 on the cover plate 132 are misaligned, allowing the airflow entering from the cover plate 132 to turn laterally. The lateral turning of the airflow increases the airflow resistance and reduces the flow velocity, making it easier for water in the airflow to settle due to gravity, thereby reducing the direct flow of water into the area of ​​the electronic control component 200 and improving the water blocking effect of the second baffle 800.

[0131] In some embodiments, please refer to Figure 6 , Figures 9 to 11 The direction from the first plate segment 132a to the second plate segment 132b is the second direction, and the length direction of the air vent 831 extends along the second direction; there are multiple air vents 831, which are arranged at intervals along the first direction, or multiple air vents 831 are arrayed on the third baffle 830 and arranged at intervals.

[0132] The second direction is as follows Figure 6 As shown, the air vent 831 extends along the second direction, allowing air to pass through the second baffle 820 more evenly and preventing air from concentrating in one place. By setting the air vent 831 along the second direction, the air circulation path can be expanded and the air intake volume can be increased. Compared with the technical solution where the air vent 830 extends along the first direction, the structural strength of the second baffle 800 can also be improved.

[0133] Furthermore, there are multiple air inlets 831. Providing multiple air inlets 831 significantly increases airflow and further enhances heat dissipation. Multiple air inlets can be evenly distributed on the second baffle 820, reducing air concentration and making airflow within the second receiving cavity 15 more efficient, carrying away more heat and thus improving heat dissipation.

[0134] Furthermore, multiple air vents 831 are arranged at intervals along the first direction, or multiple air vents 831 are arrayed on the second baffle 820 and arranged at intervals. By setting multiple air vents 831 on the second baffle 820 and arranging them at intervals, airflow can be further enhanced. The spaced arrangement design allows air to be distributed more evenly inside the equipment, further reducing the accumulation of heat.

[0135] Furthermore, the second baffle plate 800 is also provided with a support piece 840, which is connected to the edge of the air passage 831 and is located between the second baffle plate 800 and the cover plate 132. In this embodiment, the support piece 840 is provided between the second baffle plate 800 and the cover plate 132 to keep the air passage distance between the second baffle plate 800 and the cover plate 132 relatively uniform and reduce air intake fluctuations.

[0136] In some embodiments, please refer to Figure 11 The air vent 831 has a first edge 832 and a second edge 833 that are opposite to and spaced apart. The first edge 832 is close to the first plate segment 132a; the second edge 833 is close to the second plate segment 132b. Each air vent 831 has at least one support piece 840 on its first edge 832 and at least one support piece 840 on its second edge 833. The support piece 840 extends obliquely from the second baffle plate 800 toward the cover plate 132.

[0137] The first edge 832 is close to the first plate segment 132a, and the second edge 833 is close to the second plate segment 132b; the air vent 831 extends along the second direction, that is, the first edge 832 and the second edge 833 define the length of the air vent 831 along the second direction.

[0138] In this embodiment, the support plate 840 is connected to the edge of the air vent 831 by stamping the shape of the support plate 840 and the air vent 831 from the plate used to make the second baffle plate 800. Then, the support plate 840 is pushed according to its corresponding included angle and tilt direction. This design has a simple structure, simple processing technology, and strong practicality.

[0139] Furthermore, in some embodiments, the support piece 840 located at the first edge 832 has a first included angle with the surface where the air vent 831 is located, the first included angle being less than 90°, and the support piece 840 located at the second edge 833 has a second included angle with the surface where the air vent 831 is located, the second included angle being less than 90°.

[0140] For ease of understanding, the support piece 840 located at the first edge 832 is referred to as the first support piece 840, and the support piece 840 located at the second edge 833 is referred to as the second support piece 840. The first support piece 840 has a first included angle with the surface where the air vent 831 is located, such as... Figure 11 As shown in α1, the second support plate 840 and the surface where the air vent 831 is located have a second included angle, as shown in α1. Figure 11 As shown in α2, the values ​​of the first included angle or the second included angle may be equal or unequal. For example, the values ​​of α1 and α2 include, but are not limited to, 10°, 20°, 30°, 40°, 45°, 50°, 60°, 70°, 80° or 89°.

[0141] In this embodiment, the range of the first included angle and the second included angle is less than 90°, which can improve the structural strength of the second baffle plate 800, guide the airflow that is about to enter the air inlet 831, reduce wind resistance, and reduce air intake fluctuations.

[0142] In some other embodiments, the support piece 840 located at the first edge 832 has a first included angle with the surface where the air vent 831 is located, and the first included angle is less than 90°. In still other embodiments, the support piece 840 located at the second edge 833 has a second included angle with the surface where the air vent 831 is located, and the second included angle is less than 90°.

[0143] In some embodiments, please refer to Figure 15 And further reading Figures 1 to 3The heat exchange module 10 includes a housing 100, a partition 600, a heat exchange assembly 700, and an electrical control assembly 200. The housing 100 has opposing first sidewalls 101 and second sidewalls 102, with the direction from the first sidewall 101 to the second sidewall 102 being a first direction. The first sidewall 101 is provided with a main air outlet 101a. The partition 600 is disposed inside the housing 100, forming at least a first receiving cavity 14 extending along the first direction and at least a second receiving cavity 102 extending along the first direction between the partition 600 and the housing 100. 5. The second receiving cavity 15 has a first air inlet 11 communicating with the external space and a first air outlet 12 communicating with the first receiving cavity 14. The first air inlet 11 and the first air outlet 12 are located between the first side wall 101 and the second side wall 102 and are located closer to the second side wall 102. The heat exchange assembly 700 includes a heat exchanger 720 and a fan 710. The heat exchanger 720 is located in the first receiving cavity 14 and the fan 710 is located on the side of the first receiving cavity 14 closer to the first side wall 101. The electrical control assembly 200 is located in the second receiving cavity 15.

[0144] The first air inlet 11 and the first air outlet 12 can each be formed by a single large opening, multiple small openings, or numerous small holes. The shapes of the openings of the first air inlet 11 and the first air outlet 12 can be regular shapes such as circles, ovals, or squares, or other regular or irregular shapes. The distance between the first air inlet 11 and the first sidewall 101 (e.g., ...) Figure 15 h1) is greater than the distance between the first air inlet 11 and the second sidewall 102 (e.g. Figure 15 h2); and the distance between the first air outlet 12 and the first sidewall 101 (e.g., ... Figure 15 h3) is greater than the distance between the first air outlet 12 and the second side wall 102 (e.g. Figure 15 (h4). In this embodiment, the distance refers to the minimum straight-line distance.

[0145] The first air inlet 11 and the first air outlet 12 are located between the first sidewall 101 and the second sidewall 102, and are positioned closer to the second sidewall 102. The first air inlet 11 is located between the first sidewall 101 and the second sidewall 102, and is positioned closer to the second sidewall 102. The first air outlet 12 is also located between the first sidewall 101 and the second sidewall 102, and is positioned closer to the second sidewall 102. At least a portion of the second receiving cavity 15 extends along the first direction, and the second receiving cavity 15 is used to install the electronic control assembly 200. The first air inlet 11 and the first air outlet 12 are usually located on opposite sides of the electronic control component 200 (usually on both sides of the thickness direction of the circuit board 210). Thus, the first air inlet 11 and the first air outlet 12 are arranged closer to the second side wall 102 than the first side wall 101, so that the airflow entering the second receiving cavity 15 from the first air inlet 11 first bypasses the electronic control component 200 in the process of flowing to the first air outlet 12, forming a bend flow channel, thereby enhancing the airflow disturbance effect and extending the heat exchange path of the airflow on the surface of the electronic control component 200.

[0146] In the technical solution of this embodiment, since the first air inlet 11 and the first air outlet 12 are arranged closer to the second side wall 102 than the first side wall 101, the airflow entering the second receiving cavity 15 from the first air inlet 11 first bypasses the electronic control component 200 during its flow to the first air outlet 12, forming a bend in the flow channel. This bend in the flow channel generates strong disturbance and vortex effect, which helps to break the thermal boundary layer on the surface of the electronic control component 200, thereby enhancing heat exchange and improving heat dissipation efficiency. Secondly, the bend in the flow channel makes the airflow travel longer in the second receiving cavity 15, and the contact time between the cold air and the electronic control component 200 is also increased accordingly, which helps to remove more heat, thereby improving the heat dissipation effect of the electronic control component 200.

[0147] In some embodiments, please refer to Figure 15 The first air inlet 11 and the first air outlet 12 are located on the first side wall 101 at one end of the second receiving cavity 15 near the second side wall 102.

[0148] The fan 710 is located on the side of the first receiving cavity 14 near the first side wall 101. At least a portion of the first receiving cavity 14 and at least a portion of the second receiving cavity 15 extend along the direction from the first side wall 101 to the second side wall 102. The first air inlet 11 and the first air outlet 12 are located at the end of the first side wall 101 near the second side wall 102 of the second receiving cavity 15; that is, the first air inlet 11 and the first air outlet 12 are located away from the fan 710.

[0149] Since the fan 710 is located near the main air outlet 101a and the first air inlet 11 is located away from the fan 710, that is, the first air inlet 11 is located away from the main air outlet 101a, which can reduce the hot airflow from the main air outlet 101a from entering the second receiving cavity 15 through the first air inlet 11, thereby forming a heat flow isolation zone and improving the heat exchange efficiency of the heat exchange module 10.

[0150] Furthermore, since the airflow near the fan 710 is turbulent and the pressure fluctuates greatly, the airflow is more stable at the location away from the fan 710. In this embodiment, the first air outlet 12 is set away from the fan 710, which can reduce the pressure imbalance caused by the suction or blowing of the fan 710, reduce the vortex effect at the first air outlet 12, and thus reduce the stagnation of the airflow after heat exchange with the electronic control component 200 in the first receiving cavity 14 or the second receiving cavity 15, thereby improving the heat exchange efficiency.

[0151] In addition, the space around the fan 710 is often compressed (the fan 710 itself is relatively large). The first air outlet 12 is located on the side of the second receiving cavity away from the fan 710, which can reduce the installation conflict between the partition 600, the electrical control component 200 and the fan 710 components, simplify the air duct layout, and facilitate the miniaturization of the heat exchange module 10.

[0152] When the first sidewall 101 is the top wall and the second sidewall 102 is the bottom wall, that is, the first air inlet 11 and the first air outlet 12 are both located near the bottom wall. At this time, the main air outlet 101a is located at the top of the heat exchange module 10. Since the distance between the first air outlet 12 and the main air outlet 101a is relatively far, it is not easy to generate vortices at the first air outlet 12. In this embodiment, the layout of setting the first air inlet 11 and the first air outlet 12 at the bottom and the main air outlet 101a at the top of the heat exchange module 10 is adopted. Cold air is introduced from the bottom and flows through the electronic control component 200 to carry away heat. Finally, it is discharged from the top main air outlet 101a. The airflow has sufficient heat exchange during the long-path flow, thereby optimizing the heat dissipation effect and improving the stability and heat dissipation efficiency of the equipment. In addition, the position of the first air inlet 11 near the bottom wall conforms to the principle of natural convection, so that cold air enters from the bottom and hot air is discharged from the top, thereby forming an efficient airflow circulation.

[0153] In this embodiment, in the first direction, the distances between the first air inlet 11 and the first air outlet 12 and the second side wall 102 can be equal. Alternatively, the first air inlet 11 may be closer to the second side wall 102 than the first air outlet 12; or the first air outlet 12 may be closer to the second side wall 102 than the first air inlet 11.

[0154] In some embodiments, please continue reading Figure 15The second receiving cavity 15 is provided with a duct shell 400, and a first heat dissipation duct is formed between the duct shell 400 and the inner wall of the second receiving cavity 15. The air inlet end of the first heat dissipation duct is connected to the first air inlet 11, and the air outlet end of the first heat dissipation duct is connected to the first air outlet 12. The electronic control component 200 includes a circuit board 210 and a heat sink 220 connected to the circuit board 210. The heat sink 220 is disposed in the first heat dissipation duct. The heat sink 220 is disposed closer to the first side wall 101 than the first air inlet 11 and the first air outlet 12.

[0155] The air duct shell 400 and the inner wall of the second receiving cavity 15 form a first heat dissipation air duct, which guides the airflow from the first air inlet 11 to the first air outlet 12, reducing airflow diffusion loss. The heat sink 220 is disposed in the first heat dissipation air duct to prevent some airflow from flowing directly to the first air outlet 12 without passing through the heat sink 220. The heat sink 220 removes heat from its surroundings through airflow. The placement of the heat sink 220 improves the heat dissipation efficiency of the circuit board 210.

[0156] The radiator 220 is positioned closer to the first sidewall 101 than the first air inlet 11 and the first air outlet 12. The distance between the radiator 220 and the first sidewall 101 is as follows: Figure 15 As shown in h5, since the radiator 220 is located within the first heat dissipation duct, the air intake stage of the first heat dissipation duct is as follows: the cold airflow enters the first heat dissipation duct from the first air inlet 11 (near the second side wall 102) and flows along the duct shell 400 towards the first side wall 101; when the airflow reaches the radiator 220 (near the first side wall 101), it is forced to change direction due to the obstruction of the radiator 220 fins and the constraint of the duct shell 400, and the mainstream airflow diffuses along the surface of the radiator 220; finally, the airflow converges from both sides or around the radiator 220 and flows out from the first air outlet 12 (near the second side wall 102); thus, the airflow has a relatively large turning radius within the first heat dissipation channel, and the moderate turbulence generated at the turning point disrupts the boundary layer, improves the heat transfer coefficient of the radiator 220 surface, and also makes the airflow more evenly distributed on the surface of the radiator 220, preventing the problem of local overheating.

[0157] In some embodiments, please continue reading Figure 15 The heat dissipation duct includes an air inlet section and an air outlet section. The air inlet section extends along a third direction, and the air outlet section extends along a fourth direction. The angle between the fourth direction and the third direction is not less than 45°.

[0158] For example, third-party and fourth-party directions, such as Figure 15 As shown, the angle between the fourth direction and the third direction is not less than 45°. For example, it can be 45°, 60°, 75°, 90°, 100°, 120°, 135°, 150°, 180°, etc., which will not be listed here.

[0159] In this embodiment, the angle between the airflow in the inlet section and the outlet section is not less than 45°, which can enhance the turbulence effect of the airflow and periodically disrupt the thermal boundary layer, thereby improving the heat transfer coefficient of the airflow and the electronic control component 200; reducing the accumulation of heat in local areas due to poor airflow, effectively removing the heat generated by the electronic control component 200, thereby improving the overall heat dissipation effect.

[0160] In some embodiments, the air duct housing 400 includes a second air duct plate 420, which divides at least a portion of the second receiving cavity 15 into an air inlet cavity 18 extending at least a portion along a third direction and an air outlet cavity 19 extending at least a portion along a fourth direction. A first air inlet 11 communicates with the air inlet cavity 18 to form an air inlet section, and a first air outlet 12 communicates with the air outlet cavity 19 to form an air outlet section.

[0161] The connection between the air inlet cavity 18 and the air outlet cavity 19 can be located between the inner walls of the second air duct plate 420 and the second receiving cavity 15, or it can be located on the second air duct plate 420. In this embodiment, the radiator 220 can be located in either the air inlet cavity 18 or the air outlet cavity 19; preferably, the radiator 220 is located in the air outlet cavity 19. In other embodiments, a connecting cavity can be provided between the air inlet cavity 18 and the air outlet cavity 19, and the radiator 220 can be located within this connecting cavity.

[0162] The technical solution of this embodiment divides the second receiving cavity 15 into an air inlet cavity 18 and an air outlet cavity 19 by using the second air duct plate 420. The air flow path is clearly defined, which effectively isolates the air inflow and outflow areas, thereby improving the efficiency of air flow.

[0163] In some embodiments, the second air duct plate 420 is provided with a second air duct opening 421, and the air inlet cavity 18 and the air outlet cavity 19 are connected through the second air duct opening 421. The second air duct opening 421 is located at one end of the second air duct plate 420 away from the second side wall 102.

[0164] By positioning the second air duct opening 421 away from the second sidewall 102, the direction and speed of airflow can be effectively controlled, ensuring that the air does not excessively disturb the temperature balance within the system during heat dissipation. After cold air flows into the air inlet cavity 18, it enters the air outlet cavity 19 through an optimized airflow path, allowing hot air to be discharged in a timely manner. This ensures stable heat dissipation of the system and avoids local overheating or temperature fluctuations.

[0165] In some embodiments, the radiator 220 is disposed at the second air duct opening 421, and the radiator 220 is located in the air outlet cavity 19. The radiator 220 is disposed at the second air duct opening 421, that is, the radiator 220 is disposed at the connection between the air inlet cavity 18 and the air outlet cavity 19, so that air can flow through the radiator 220 sufficiently, thereby improving the heat dissipation efficiency. The radiator 220 is located in the air outlet cavity 19.

[0166] In some embodiments, the air duct housing 400 includes a first air duct plate 410, which divides the second receiving cavity 15 to form an electrical control cavity 16 and a heat dissipation cavity 17 arranged along a first direction, and a second air duct plate 420 divides the heat dissipation cavity 17 into an air inlet cavity 18 and an air outlet cavity 19; at least a portion of the circuit board 210 is located in the electrical control cavity 16, and the heat sink 220 is located in the heat dissipation cavity 17.

[0167] Since the first air inlet 11 and the first air outlet 12 are located at the end of the second receiving cavity 15 away from the first air duct plate 410, in this embodiment, the second air duct opening 421 is located at the end of the second air duct plate 420 close to the first air duct plate 410. After the external air enters the air inlet cavity 18 from the first air inlet 11, it flows towards the first side wall 101, and then flows from the air outlet cavity 19 towards the second side wall 102 through the second air duct opening 421, and finally flows out from the first air outlet 12 into the first receiving cavity 14. In this way, the path of the airflow in the heat dissipation cavity 17 can be extended, the heat dissipation dead angle can be reduced, and the heat dissipation effect can be enhanced.

[0168] In some embodiments, the duct housing 400 further includes a mounting bracket 430, on which the first duct plate 410 and the second duct plate 420 are disposed; the mounting bracket 430 is mounted on the separator 600, or the mounting bracket 430 is mounted on the housing 100.

[0169] The first air duct plate 410 and the second air duct plate 420 are first installed on the mounting bracket 430, and then installed as a whole into the second receiving cavity 15. At this time, the entire air duct shell 400 can be installed on the partition 600 or on the outer shell 100. This facilitates the disassembly and assembly of the first air duct plate 410 and the second air duct plate 420, especially when the electrical control component 200 needs to be maintained.

[0170] Preferably, the first air duct plate 410, the second air duct plate 420, and the mounting bracket 430 are integrally formed. In this embodiment, by integrally forming the mounting bracket 430, the first air duct plate 410, and the second air duct plate 420, the structure of the air duct shell 400 can be further simplified, thereby simplifying the internal structure of the heat exchange module 10.

[0171] In some embodiments, the housing 100 includes a top cover 110, a chassis 120, and a connecting housing 130. The top cover 110 forms a first sidewall 101, the chassis 120 forms a second sidewall 102, and the connecting housing 130 is connected between the chassis 120 and the top cover 110. A partition 600 is installed on at least one of the top cover 110, the chassis 120, and the connecting housing 130. The partition 600 extends along a first direction. A first air inlet 11 is located at one end of the connecting housing 130 near the chassis 120, and a first air outlet 12 is located at one end of the partition 600 near the chassis 120.

[0172] In this embodiment, the first air inlet 11 is located at the end of the connecting housing 130 near the chassis 120, and the first air outlet 12 is located at the end of the partition 600 near the chassis 120. This allows the airflow to form a bend in the second receiving cavity 15 where the electronic control component 200 is located, and to flow along the surface of the electronic control component 200, thereby enhancing the heat exchange efficiency. At the same time, the structure is compact and the heat dissipation channel is stable, further improving the thermal management capability and operational reliability of the entire heat exchange module 10.

[0173] In some embodiments, the connecting housing 130 includes a surrounding plate 131 and a cover plate 132. The surrounding plate 131 has a first opening 130a, and the cover plate 132 covers the first opening 130a. A partition 600 is provided at the first opening 130a. A first receiving cavity 14 is defined between one side of the partition 600 and the surrounding plate 131, and a second receiving cavity 15 is defined between the other side of the partition 600 and the cover plate 132. A first air inlet 11 is provided on the cover plate 132, and a first air outlet 12 is provided on the partition 600.

[0174] In this embodiment, the first air inlet 11 is provided on the cover plate 132 and the first air outlet 12 is provided on the partition 600, forming an effective airflow path, enhancing the heat exchange efficiency between air and heat source, thereby optimizing the heat dissipation effect and improving the heat dissipation effect of the electronic control component 200.

[0175] In some embodiments, the enclosure 131 includes a first side plate 131a, a second side plate 131b, and a support plate 131c. The first side plate 131a is connected between the top cover 110 and the chassis 120. The second side plate 131b is disposed on the chassis 120. The support plate 131c is disposed on the second side plate 131b and located on the side of the second side plate 131b away from the first receiving cavity 14. The support plate 131c is opposite to and spaced apart from the second side wall 102. The first opening 130a is located between the support plate 131c and the top cover 110. The cover plate 132 is connected between the top cover 110 and the support plate 131c. The support plate 131c is provided with a first air inlet 11. The cover plate 132 is provided with a first air inlet 11 at one end near the support plate 131c.

[0176] In this embodiment, the support plate 131c and the cover plate 132 are respectively provided with the first air inlet 11, and the support plate 131c and the second side plate 131b are kept apart, which increases the air inlet area of ​​the second accommodating cavity 15 and effectively improves the heat dissipation effect of the electronic control component 200.

[0177] In another embodiment, the support plate 131c is provided with a first air inlet 11. In yet another embodiment, the cover plate 132 is provided with a first air inlet 11 at one end near the support plate 131c.

[0178] In some embodiments, the separator 600 includes a separator plate 610 and a mounting shell 620. The separator plate 610 extends along a first direction and has opposing first and second sides. A first receiving cavity 14 is formed between the first side of the separator plate 610 and the outer shell 100. At least a portion of the second receiving cavity 15 is located on the second side of the separator plate 610. The separator plate 610 is provided with a mounting opening 610a that passes through the first and second sides. The mounting shell 620 is located at the mounting opening 610a. One end of the mounting shell 620 near the second sidewall 102 protrudes from the first receiving cavity 14. A first air outlet 12 is located at the portion of the mounting shell 620 that protrudes from the first receiving cavity 14.

[0179] In this embodiment, by setting the first air outlet 12 on the part of the mounting shell 620 that protrudes from the first receiving cavity 14, the airflow path is optimized, airflow resistance and stagnation are reduced, heat emission efficiency is effectively improved, and the heat dissipation performance of the equipment is enhanced.

[0180] In some embodiments, the portion of the mounting shell 620 protruding from the first receiving cavity 14 is provided with a mounting groove 620a, the opening of which faces the cover plate 132. The mounting groove 620a has a first groove wall 621 and a second groove wall 622. The first groove wall 621 extends along a first direction and is disposed opposite to the cover plate 132. The electronic control component 200 is mounted on the first groove wall 621. The second groove wall 622 is disposed on the first groove wall 621 and located at one end of the first groove wall 621 near the second side wall 102. The first air outlet 12 is provided with the second groove wall 622 and is located at one end of the first groove wall 621 near the second groove wall 622. In this embodiment, by setting the first air outlet 12 on the second groove wall 622 or the first groove wall 621 near the second groove wall 622 of the protruding portion of the mounting shell 620, the airflow path and heat dissipation effect are optimized.

[0181] In other embodiments, the first air outlet 12 may be provided only in the second groove wall 622, or the first air outlet 12 may be provided only at the end of the first groove wall 621 near the second groove wall 622.

[0182] The heat exchange module 10 operates in various environments, such as high-temperature environments and high-temperature and high-humidity environments. When the electronic control component 200 in the heat exchange module 10 adopts an air-cooled heat dissipation solution, the second receiving cavity 15 where the electronic control component 200 is installed is usually semi-open. When it is in a high-humidity environment, the electronic control component 200 is at risk of condensation. Condensation (also known as dew) refers to the phenomenon that when the surface temperature of an object drops below the dew point temperature of the surrounding air, water vapor in the air condenses into liquid water on the surface of the object.

[0183] Based on this, in one embodiment, a heat exchange module 10 is proposed to reduce the condensation direction of the electronic control component 200. In this embodiment, the heat exchange module 10 includes a housing 100, a partition 600, a heat exchange component 700, and an electronic control component 200. The housing 100 has opposing first sidewalls 101 and second sidewalls 102, with the direction from the first sidewall 101 to the second sidewall 102 being a first direction. The first sidewall 101 is provided with a main air outlet 101a. The partition 600 is disposed inside the housing 100, and a first receiving cavity 14 and a second receiving cavity 102 extending at least partially along the first direction are formed between the partition 600 and the housing 100. 5. The main air outlet 101a is connected to the first receiving cavity 14. The second receiving cavity 15 includes an electrical control cavity 16 and a heat dissipation cavity 17 arranged along the first direction. The heat dissipation cavity 17 is provided with a first air inlet 11 that connects to the external space and a first air outlet 12 that connects to the first receiving cavity 14. The heat exchange assembly 700 includes a heat exchanger 720 and a fan 710. The heat exchanger 720 is located in the first receiving cavity 14, and the fan 710 is located on the side of the first receiving cavity 14 near the first side wall 101. The electrical control assembly 200 includes a circuit board 210 and a heat sink 220. At least part of the circuit board 210 is located in the electrical control cavity 16, and the heat sink 220 is connected to the circuit board 210 and located in the heat dissipation cavity 17.

[0184] The second receiving cavity 15 includes two parts: an electrical control cavity 16 and a heat dissipation cavity 17. The electrical control cavity 16 and the heat dissipation cavity 17 are usually separated by a partition. The electrical control cavity 16 and the heat dissipation cavity 17 may be connected or disconnected. In the case where the electrical control cavity 16 and the heat dissipation cavity 17 are connected, the connection opening between the electrical control cavity 16 and the heat dissipation cavity 17 is very small, or a dehumidifying element 60 is provided at the connection opening, so as to at least reduce the moisture entering the electrical control cavity 16.

[0185] The electrical control cavity 16 is a space for housing the circuit board 210. The heat dissipation cavity 17 is mainly responsible for the installation of the heat sink 220 and assists in the heat dissipation of the circuit board 210. Of course, a small portion of the circuit board 210 can also be placed in the heat dissipation cavity 17, that is, at least part of the circuit board 210 is located in the electrical control cavity 16, and the heat sink 220 is connected to the circuit board 210 and located in the heat dissipation cavity 17. For example, with the first sidewall 101 as the top wall and the second sidewall 102 as the bottom wall, the electrical control cavity 16 is the end of the second receiving cavity 15 near the first sidewall 101, and the heat dissipation cavity 17 is located at the end near the second sidewall 102. Thus, the electrical control cavity 16 is equivalent to the upper cavity and the heat dissipation cavity 17 is the lower cavity, or directly, the electrical control cavity 16 is located above the heat dissipation cavity 17.

[0186] The electrical control cavity 16 is used to install the circuit board 210, which is equipped with electronic components. The circuit board 210 needs to be electrically connected to the fan 710 and compressor 20 through wiring, and also needs to be electrically connected to an external power source through wiring. In this embodiment, the wiring position of the circuit board 210 is located inside the electrical control cavity 16, that is, the wiring position of the electrical control component 200 is located at the upper part of the air conditioner outdoor unit. When the humidity of the working environment of the air conditioner outdoor unit is high, placing the electrical control cavity 16 above the heat dissipation cavity 17 can help the electrical control cavity 16 maintain a lower humidity and achieve a certain degree of dry and wet separation. The circuit board 210 is placed inside the electrical control cavity 16, and the wiring position on the circuit board 210 is also located inside the electrical control cavity 16, which can reduce the direct contact of hot and humid air in the heat dissipation cavity 17 with the circuit board 210 and reduce the risk of condensation on the surface of the circuit board 210 and its wiring.

[0187] The heat dissipation cavity 17 is provided with a first air inlet 11 that connects to the external space and a first air outlet 12 that connects to the first receiving cavity 14. The first air inlet 11, the heat dissipation cavity 17 and the first air outlet 12 form a first heat dissipation air duct. As introduced above, the heat sink 220 is mainly used to accelerate the heat dissipation of the part of the circuit board 210 that generates a large amount of heat.

[0188] The technical solution of this embodiment uses the relatively independent arrangement between the heat dissipation cavity 17 and the electrical control cavity 16. The circuit board 210 is mainly set in the electrical control cavity 16, and the heat sink 220 is connected to the circuit board 210 and located in the heat dissipation cavity 17. This can reduce the direct contact between the hot and humid air in the heat dissipation cavity 17 and the circuit board 210, and reduce the risk of condensation on the surface of the circuit board 210 and its wiring positions.

[0189] In some embodiments, please refer to Figure 2 And further reading Figure 3 The second receiving cavity 15 is provided with a first air duct plate 410, which divides the second receiving cavity 15 into an electrical control cavity 16 and a heat dissipation cavity 17.

[0190] In one embodiment, an air duct opening may be provided on the first air duct plate 410 to connect the electronic control cavity 16 and the heat dissipation cavity 17, or an air duct opening may be formed between the inner walls of the first air duct plate 410 and the second receiving cavity 15 to connect the electronic control cavity 16 and the heat dissipation cavity 17; in other embodiments, the separator 600 itself may be constructed to separate the electronic control cavity 16 and the heat dissipation cavity 17.

[0191] In this embodiment, the second receiving cavity 15 is divided into an electronic control cavity 16 and a heat dissipation cavity 17 by the first air duct plate 410, which facilitates the development of a series of products and improves the versatility of the heat exchange module 10.

[0192] In some embodiments, the first air duct plate 410 is provided with a first air duct opening 411 connecting the electronic control cavity 16 and the heat dissipation cavity 17, and the electronic control cavity 16 is provided with a second air outlet 13 connecting the first receiving cavity 14; the first air inlet 11, the heat dissipation cavity 17 and the first air outlet 12 are sequentially connected to form a first heat dissipation air duct; the first air inlet 11, the heat dissipation cavity 17, the first air duct opening 411, the electronic control cavity 16 and the second air outlet 13 are sequentially connected to form a second heat dissipation air duct.

[0193] As described above, the heat sink 220 is mainly used to accelerate the heat dissipation of the part of the circuit board 210 that generates a lot of heat. In this embodiment, by setting an independent first heat dissipation air duct for part of the heat sink 220, the heat of this part is discharged in time, reducing the impact of this part of the heat entering the electronic control cavity 16 on other components of the circuit board 210. Secondly, air enters the heat dissipation cavity from the first air inlet 11, and after passing through the heat dissipation cavity 17, a small part of the airflow passes through the electronic control cavity 16, cools the circuit board 210, and is discharged through the second air outlet 13. The second heat dissipation air duct provides additional cooling protection for the circuit board 210, further improving the heat dissipation efficiency of the circuit board 210.

[0194] Compared to the air duct opening formed between the inner walls of the first air duct plate 410 and the second receiving cavity 15, in this embodiment, the first air duct opening 411 is located on the first air duct plate 410. The first air duct opening 411 can directly guide cold air to the parts of the circuit board 210 with large heat generation, such as inductors, thereby reducing heat accumulation caused by airflow detours. Secondly, the edges of the first air duct opening 411 can be rounded or smoothly transitioned to reduce wind resistance and improve the efficiency of the fan or natural convection. In addition, the same air duct plate can be matched with forced air cooling, natural convection or liquid cooling heat dissipation requirements by changing different air duct opening designs (such as circular holes, strip holes, louvered types). Furthermore, since the first air duct opening 411 is located on the first air duct plate 410, the parameters of the first air duct opening 411 (such as opening ratio, position) can be standardized, which is convenient for product series development. The same air duct plate can be matched with forced air cooling, natural convection or liquid cooling heat dissipation requirements by changing different air duct opening designs (such as circular holes, strip holes, louvered types).

[0195] In some embodiments, a second air duct plate 420 is provided in the heat dissipation cavity 17, which divides the heat dissipation cavity 17 into an air inlet cavity 18 and an air outlet cavity 19. The second air duct plate 420 is provided with a second air duct opening 421, through which the air inlet cavity 18 and the air outlet cavity 19 are connected. A first air inlet 11 is connected to the air inlet cavity 18, a first air outlet 12 is connected to the air outlet cavity 19, a first air duct opening 411 is connected to the air inlet cavity 18 and the electrical control cavity 16, and a radiator 220 is provided in the air outlet cavity 19.

[0196] Based on the previous embodiment, a second air duct plate 420 is provided in the heat dissipation cavity 17. The second air duct plate 420 divides the heat dissipation cavity 17 into an air inlet cavity 18 and an air outlet cavity 19. The first air inlet 11 is connected to the air inlet cavity 18, and the first air outlet 12 is connected to the air outlet cavity 19. A second air duct opening 421 is provided at one end of the second air duct plate 420 near the first air duct plate 410. The air inlet cavity 18 and the air outlet cavity 19 are connected through the second air duct opening 421. The radiator 220 is located in the air outlet cavity 19.

[0197] The second air duct plate 420 further subdivides the heat dissipation cavity 17 into an air inlet cavity 18 and an air outlet cavity 19, refining the management of airflow. Through this separation, the airflow entering from the first air inlet 11 is guided into the air inlet cavity 18, and then the airflow is divided into two paths. One path passes through the second air duct opening 421 and enters the air outlet cavity 19 to dissipate heat from the heat sink 220, and finally exits from the first air outlet 12. The other path passes through the first air duct opening 411 and enters the electronic control cavity 16 to dissipate heat from the control unit 211 or other parts of the power drive unit 212, and finally exits from the second air outlet 13.

[0198] In this embodiment, the second air duct plate 420 further divides the heat dissipation cavity 17, refining airflow management and making airflow more orderly. The heat exchange between the two heat dissipation air ducts is independent, isolating the thermal influence between heat sources, reducing overall temperature fluctuations, and improving the uniformity of heat dissipation. Furthermore, in this embodiment, by controlling the area of ​​the first air duct opening 411 and the second air duct opening 421, most of the airflow can flow along the first heat dissipation air duct to dissipate heat from the parts of the circuit board that generate more heat, while a smaller portion of the airflow flows along the second heat dissipation air duct to dissipate heat from the parts of the circuit board that generate less heat. This improves the heat dissipation efficiency of the electronic control components.

[0199] In some embodiments, the opening area of ​​the first air duct 411 is smaller than the opening area of ​​the second air duct 421.

[0200] As mentioned earlier, the heat sink 220 is mainly used to accelerate the heat dissipation of the heat-generating parts of the circuit board 210. The components in the electronic control cavity 16 generate relatively little heat. The opening area of ​​the first air duct 411 is smaller than the opening area of ​​the second air duct 421, allowing more airflow to enter the exhaust cavity 19 for heat exchange with the heat sink 220, and less airflow to enter the electronic control cavity 16 for heat exchange with the components within the electronic control cavity 16. This allows for effective management of the airflow between the electronic control cavity 16 and the heat dissipation cavity 17. In other words, the ratio of airflow entering the electronic control cavity 16 to entering the exhaust cavity 19 can be controlled by the size of the opening area of ​​the first air duct 411, thereby improving the heat dissipation efficiency of the electronic control component 200. Preferably, the opening area of ​​the first air duct 411 is less than or equal to one-quarter of the opening area of ​​the second air duct 421. For example, the opening area of ​​the first air duct 411 can be one-quarter, one-fifth, one-sixth, or one-tenth of the opening area of ​​the second air duct 421, etc., which will not be listed here.

[0201] In some embodiments, please refer to Figure 3 , Figure 7 and Figure 12 In order to further reduce the humidity of the electrical control cavity 16 and thus reduce the risk of condensation on the circuit board and its wiring, a dehumidifier 60 is provided at the first air duct opening 411.

[0202] The dehumidifier 60 is typically made of breathable and absorbent materials such as cotton or foam. Examples include sponges, foam, non-woven fabrics, aerogels, and honeycomb-shaped moisture-absorbing and breathable panels (porous ceramic or plastic substrates with a surface-loaded desiccant, such as lithium chloride). The honeycomb channels ensure airflow while simultaneously absorbing moisture. The dehumidifier 60 can be in block or sheet form, or other shapes.

[0203] In this embodiment, the dehumidifier 60 typically covers the surface of the first air duct opening 411, so that the airflow entering the electronic control cavity 16 first passes through the dehumidifier 60; thus, by setting the dehumidifier 60, the humidity of the airflow entering the electronic control cavity 16 can be reduced, further reducing the risk of condensation on the circuit board and its wiring.

[0204] It is worth mentioning that, in this embodiment, the inner walls of the first air duct plate 410 and the second receiving cavity 15 are sealed together by a second sealing member 80 to further reduce the amount of moisture entering the electrical control cavity 16.

[0205] In some embodiments, the first air duct plate 410 is provided with a receiving groove 412, the receiving groove 412 has a groove opening and a bottom groove wall opposite to the groove opening, the first air duct opening 411 is provided on the bottom groove wall of the receiving groove 412, and the dehumidifying component 60 is provided in the receiving groove 412.

[0206] The receiving slot 412 is a space specifically designed to accommodate the dehumidifier 60, allowing it to be fixed in a suitable position. The receiving slot 412 has an opening and a bottom wall. In this embodiment, to ensure that the airflow entering the electronic control cavity 16 first flows through the dehumidifier 60, the first air duct opening 411 is located on the bottom wall of the receiving slot 412. The dehumidifier 60 is relatively small in size. Generally, the dimensions of the receiving slot 412 and the dehumidifier 60 are matched.

[0207] In some embodiments, the opening of the receiving groove 412 is located on the side of the first air duct plate 410 facing the electrical control cavity 16, and the dehumidifying component 60 is spaced apart from the bottom wall of the receiving groove 412.

[0208] In this embodiment, the electrical control cavity 16 is located above the heat dissipation cavity 17, and the opening of the receiving groove 412 is located on the side of the first air duct plate 410 facing the electrical control cavity 16. That is, the opening of the receiving groove 412 faces upward. This arrangement allows the first air duct plate 410 to support the dehumidifying component 60, reducing the risk of the dehumidifying component 60 falling due to excessive weight after absorbing excessive moisture. The dehumidifying component 60 does not directly contact the bottom wall of the receiving groove 412, but is spaced apart, which is beneficial for uniform airflow.

[0209] In some embodiments, the side wall of the receiving groove 412 is provided with a protrusion 413, the protrusion 413 is located at one end of the side wall near the groove opening, and the bottom wall of the receiving groove 412 is provided with a plurality of support ribs 414, and the dehumidifying element 60 is located between the support ribs 414 and the protrusion 413.

[0210] The protrusion 413 and the support rib 414 are located on the side wall of the receiving groove 412, near the opening. The protrusion 413 provides stable restraint and support for the dehumidifier 60, preventing it from shifting or changing position under airflow. The support rib 414 is located on the bottom wall of the receiving groove 412. Multiple support ribs 414 help to maintain spacing between the dehumidifier 60 and the bottom wall of the receiving groove 412. Through the arrangement of the support rib 414 and the protrusion 413, the dehumidifier 60 can maintain good moisture adsorption efficiency when airflow passes through, thereby effectively reducing the humidity in the electronic control cavity 16.

[0211] In any of the foregoing embodiments, please refer to Figure 15 The circuit board 210 includes a control unit 211 and a power drive unit 212. The control unit 211 is located in the electrical control cavity 16, and at least part of the power drive unit 212 is located in the electrical control cavity 16. The heat sink 220 is connected to the power drive unit 212 and is located in the heat dissipation cavity 17.

[0212] The control unit 211 is located in the electrical control cavity 16. The power drive unit 212 may be partially located in the electrical control cavity 16 and partially located in the heat dissipation cavity 17. In this case, the wiring components of the power drive unit 212 are typically located within the electrical control cavity 16. Alternatively, the entire power drive unit 212 may be located within the electrical control cavity 16. In this embodiment, the heat dissipation efficiency of the electrical control component 200 is further improved.

[0213] In some embodiments, please refer to Figure 2 and Figure 7 The heat exchange module 10 includes a wiring assembly 500 disposed in the electrical control cavity 16. The wiring assembly 500 includes a wiring frame 510 and a plurality of wiring terminals 520 disposed in the wiring frame 510. The wiring frame 510 is mounted on the separator 600, and some of the wiring terminals 520 are electrically connected to the circuit board 210 through wiring.

[0214] Terminal blocks 520 are electrical connection points that connect to external power sources or electrical control components 200, transmitting signals or power to the corresponding components via cables. The number and layout of terminal blocks 520 can be adjusted as needed to meet different electrical connection requirements.

[0215] The terminal block 510 is mounted on the electrical control cavity 16, providing fixation and support, allowing the terminal blocks 520 to be stably arranged and capable of bearing a certain electrical connection load. Multiple terminal blocks 520 are mounted on the terminal block 510, serving as interfaces for electrical connections within and outside the electrical control assembly 200. Each terminal block 520 may have different functions, specifically determined by the connecting components or circuit board. Some terminal blocks 520 are electrically connected to the circuit board 210 via wiring, while others are electrically connected to external electrical equipment or systems of the electrical control assembly 200 via wiring, enabling the circuit board 210 to exchange data or supply power to external devices.

[0216] The arrangement of the wiring bracket 510 and terminal blocks 520 improves the stability and reliability of the electrical connections of the electrical control component 200, reducing electrical system malfunctions caused by poor electrical contact or loose wiring. The design of the terminal blocks 520 and wiring bracket 510 allows for flexible expansion or modification of the electrical control component 200 in the future, such as adding or modifying connections to external devices or adjusting electrical connections between circuit boards 210, facilitating later maintenance and upgrades of the outdoor unit 1. Furthermore, the rationally arranged terminal blocks 520 reduce mutual interference or short circuits within the electrical circuits of the electrical control component 200, thereby enhancing system safety.

[0217] In this embodiment, the wiring assembly 500 is located inside the electrical control cavity 16, which not only reduces the risk of condensation at the wiring point, but also facilitates wiring for the user since the electrical control cavity 16 is located on the upper part of the outdoor unit 1.

[0218] In some embodiments, the terminal block 510 is located on the side of the circuit board 210 facing the cover plate 132, and the terminal block 510 is spaced apart from the first air duct plate 410.

[0219] In this embodiment, by setting the wiring bracket 510 on the side of the circuit board 210 facing the cover plate 132 and spaced apart from the first air duct plate 410, the wiring space layout is optimized and the convenience of wiring operation is improved.

[0220] In some embodiments, the terminal block 510 includes a terminal block 512 and two connecting arms 511 disposed at opposite ends of the terminal block 512. The terminal block 512 is spaced apart from the circuit board 210, and a plurality of terminals 520 are disposed on the terminal block 512. The two connecting arms 511 are connected to the separator 600, or the two connecting arms 511 are connected to the housing 100.

[0221] The terminal block 512, as the basic component of the terminal frame 510, is responsible for fixing and supporting multiple terminal blocks 520. It provides a stable electrical connection platform, enabling the terminal blocks 520 to be installed stably and to establish electrical connections with other components within the electrical control assembly 200 via cables. Two connecting arms 511 are angled to the terminal block 512 and located on the same side of the terminal block 512. The terminal block 512 and the connecting arms 511 together form a robust support structure, effectively isolating the terminal block 512 from the circuit board and providing stable support for the terminal block 512, effectively preventing the terminal frame 510 from loosening or deforming under external forces.

[0222] In the relevant prior art, the end of the electronic control component 200 near the fan 710 is usually also provided with a heat dissipation vent, which is usually set facing the fan 710. Since the heat exchange module 10 is usually used outdoors, when the heat exchange module 10 is rained on or in an environment with high humidity and temperature, there will be rainwater or condensation on the blades 711a of the fan 710. When the fan 710 rotates, due to the centrifugal force, the rainwater or condensation on the blades 711a of the fan 710 may be thrown out with the rotation of the blades 711a and then carried into the electronic control cavity 16.

[0223] To address the aforementioned issues, in some embodiments of this application, the heat exchange module 10 includes a housing 100, a partition 600, a heat exchange assembly 700, an electrical control assembly 200, and a first baffle plate 300. The housing 100 has opposing first sidewalls 101 and second sidewalls 102, with the direction from the first sidewall 101 to the second sidewall 102 being a first direction. The first sidewall 101 is provided with a main air outlet 101a. The partition 600 is disposed within the housing 100, forming a first receiving cavity 14 and a second receiving cavity 14 extending at least partially along the first direction between the partition 600 and the housing 100. The second cavity 15 has a main air outlet 101a connected to the first receiving cavity 14; the heat exchange assembly 700 includes a heat exchanger 720 and a fan 710, the heat exchanger 720 is located in the first receiving cavity 14, and the fan 710 is located on the side of the first receiving cavity 14 near the first side wall 101; the electrical control assembly 200 is located in the second receiving cavity 15; the first baffle 300 is located in the first receiving cavity 14 and between the partition 600 and the fan 710, the first baffle 300 is located adjacent to the fan 710, and an airflow channel 90 is formed between the first baffle 300 and the partition 600, the airflow channel 90 is connected to the second receiving cavity 15.

[0224] The fan 710 is typically an axial flow fan 710. The blade 711a design of the axial flow fan 710 allows it to provide a large flow of air at relatively low static pressure, making it suitable for scenarios requiring rapid ventilation or heat dissipation. Compared to a centrifugal fan 710, the axial flow fan 710 has a simpler structure, lower manufacturing and maintenance costs, and is suitable for large-scale applications. The axial flow fan 710 typically adopts a straight-cylinder design, making it suitable for installation in compact spaces such as air conditioner outdoor units without significantly increasing the size of the outdoor unit. Furthermore, under low wind resistance (such as in open environments), the efficiency of the axial flow fan 710 is generally superior to that of the centrifugal fan 710, making it suitable for applications with short airflow paths, such as air conditioner outdoor units. In this embodiment, placing the fan 710 at the end of the accommodating space near the first sidewall 101 improves both airflow efficiency and smoother airflow, enhancing the overall heat dissipation effect.

[0225] The first baffle plate 300 is disposed between the partition 600 and the fan 710. The first baffle plate 300 is located adjacent to the fan 710, that is, the first baffle plate 300 is in front of the partition plate 610, which can prevent water droplets (such as rainwater or condensation) on the blades 711a of the fan 710 from being thrown into the electrical control cavity 16. An airflow channel 90 is formed between the first baffle plate 300 and the partition 600, so that the gas coming out of the second receiving cavity 15 can pass through the airflow channel 90, then through the fan 710, and finally flow out from the main air outlet 101a.

[0226] The technical solution of this embodiment, by placing the first baffle plate 300 between the fan 710 and the partition 600, can prevent rainwater or condensation on the blades 711a of the fan 710 from being thrown into the electrical control cavity 16. In this way, moisture is prevented from entering the electrical control part, thereby protecting the electrical control component 200 from the influence of moisture or rain. The airflow channel 90 is formed through the gap between the baffle plate and the partition 600, so that the gas coming out of the second receiving cavity 15 can pass through the airflow channel 90, then through the fan 710, and finally flow out from the main air outlet 101a.

[0227] In some embodiments, please refer to Figures 13 to 16 The first baffle plate 300 includes a first baffle wall 310 adjacent to the fan 710 and at least one side wall 360. The first baffle wall 310 is disposed opposite to the partition 600, and an airflow channel 90 is formed between the first baffle wall 310 and the partition 600. The side wall 360 is disposed on the first baffle wall 310 and extends along the first direction. At least one side wall 360 is provided with a second air outlet 13, which is connected to the airflow channel 90 and the air inlet side of the fan 710 respectively.

[0228] The first water-blocking wall 310 is adjacent to the fan 710, meaning that the first water-blocking wall 310 is located near the radial direction of the fan blade 711a. The first water-blocking wall 310 can be arranged parallel or approximately parallel to the axis of the fan 710 to cover the water-throwing trajectory of the rotating blade 711a.

[0229] The first baffle 300 includes at least one sidewall 360, which is disposed on the first baffle 310 and extends along a first direction. In other words, the number of sidewalls 360 extending along the first direction can be one, two, or more. In one example, there is only one sidewall 360, which can be understood as the first baffle 310 having a first side and a second side, which are arranged opposite each other along the rotation direction of the fan 710. In this case, one of the first side and the second side is directly connected to the separator 600, and the other is connected to the separator 600 through the sidewall 360. In another example, there are two sidewalls 360, such as... Figure 13 and Figure 14 As shown, Figure 13 The dotted line on the right Figure 14 The dotted line on the left side indicates the sidewall 360 that has been completely cut off. In other words, in this embodiment, the opening area of ​​the second air outlet 13 is equal to the area of ​​the sidewall 360 at that location.

[0230] Compared to the usual arrangement where the top heat dissipation vent is directly facing the fan 710, this embodiment places the second vent 13 on the side. The second vent 13 is not directly connected to the movement direction of the fan blades 711a, thus avoiding the situation where the fan blades 711a throw water droplets directly towards the vent, which can reduce the water droplets on the blades 711a from being thrown into the electrical control cavity 16.

[0231] In some embodiments, please refer to Figure 16 The axial direction of the fan 710 is the first direction. The fan 710 includes blades 711a. There are at least two side walls 360, one of which is the first side wall 361 and the other is the second side wall 362. The first side wall 361 and the second side wall 362 are arranged in sequence along the rotation direction of the blades 711a. The second air outlet 13 is located on the second side wall 362.

[0232] w refers to the rotation direction of the fan 710. Along the rotation direction of the blade 711a, the first side wall 361 and the second side wall 362 are arranged in sequence. It is equivalent to the first side wall 361 being located upstream of the second side wall 362. It means that the blade 711a of the fan 710 located on the side away from the electronic control component 200 is the first blade 711a. With the first blade 711a as a reference, when the fan 710 rotates, the first blade 711a first passes the first side wall 361, then passes the first water-blocking wall 310, and then reaches the second side wall 362. At this time, the second air outlet 13 is located on the second side wall 362. It is equivalent to the second air outlet 13 being located on the leeward side, and water droplets on the fan 710 are not easily thrown into the second receiving cavity 15 from the second air outlet 13.

[0233] In some embodiments, the opening area of ​​the second air outlet 13 is S1, and the surface area of ​​the side wall 360 of the second air outlet 13 is S; wherein, S1 satisfies: 0.1S≤S1≤S.

[0234] The value of S1 includes, but is not limited to, 0.1S, 0.2S, 0.3S, 0.4S, 0.5S, 0.6S, 0.7S, 0.8S, 0.9S, or 1.0S. Figure 13 and Figure 14 As shown, the value of S1 is 1.0S.

[0235] In this embodiment, when the opening area of ​​the second air outlet 13 is small, it is more difficult for water droplets on the fan 710 to be thrown into the second receiving cavity 15 from the second air outlet 13, and the waterproof performance of the electrical control cavity 16 is better; when the opening area of ​​the second air outlet 13 is large, the heat dissipation effect of the electrical control cavity 16 is relatively better.

[0236] In some embodiments, please refer to Figure 7The separator 600 is provided with a first vent 610b, and the second receiving cavity 15 and the airflow channel 90 are connected through the first vent 610b.

[0237] The first vent 610b can be a regular shape such as a round hole, an elliptical hole, or a square hole. Of course, it can also be other irregular shapes. There are usually multiple first vents 610b, and the first vents 610b are usually micropores. In this embodiment, the first baffle plate 300, and the micropore vents on the first baffle plate 300, increase the difficulty for water droplets on the fan 710 to be thrown into the second receiving cavity 15 from the second air outlet 13.

[0238] Preferably, the first vent 610b is a circular hole with a diameter not exceeding 10 mm. The diameter of the first vent 610b is typically between 2 and 10 mm, for example, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, or 10 mm.

[0239] In some embodiments, please refer to Figure 2 and Figure 7 The separator 600 includes a separator plate 610 extending along a first direction. The separator plate 610 has a first side and a second side. A first receiving cavity 14 is formed between the first side of the separator plate 610 and the housing 100. At least a portion of the second receiving cavity 15 is located on the second side of the separator plate 610. A first baffle plate 300 is located between the separator plate 610 and the fan 710. An airflow channel 90 is formed between the separator plate 610 and the first baffle plate 300. A first vent 610b is provided at one end of the separator plate 610 near the first sidewall 101.

[0240] In this embodiment, by setting the first vent 610b at one end of the partition plate 610 near the first side wall 101, the airflow can flow more smoothly from the second receiving cavity 15 to the airflow channel 90 when passing through the airflow channel 90, reducing the airflow resistance and tortuosity. This design helps to improve the flow efficiency of the airflow and enhance the ventilation and heat dissipation effect.

[0241] In some embodiments, the separator 600 further includes a mounting shell 620 disposed on the separator plate 610; a portion of the separator plate 610 having at least a first vent hole 610b is spaced apart from the mounting shell 620; the electronic control assembly 200 includes a circuit board 210 mounted on the mounting shell 620 and located on the side of the mounting shell 620 opposite to the separator plate 610.

[0242] Mounting housing 620 is disposed on partition plate 610 and serves as a base for mounting electronic control components 200 (such as circuit board 210). Mounting housing 620 provides a robust and stable foundation, enhancing the stability and reliability of electronic control components 200. Simultaneously, it provides space for easy installation, maintenance, and replacement of electronic control components 200.

[0243] The spacing between the partition plate 610 and the mounting housing 620 (i.e., the portion where the first vent 610b is located) provides a ventilation path, facilitating airflow and preventing overheating of the electronic control component 200. This spacing forms an airflow channel 90, allowing air to flow between the partition plate 610 and the mounting housing 620. Furthermore, the spacing between the partition plate 610, at least the portion with the first vent 610b, and the mounting housing 620 further extends the distance between the circuit board 210 and the second air outlet 13, making it more difficult for water droplets on the fan 710 to be flung into the electronic control component 200 from the second air outlet 13, thus improving the waterproof performance of the electronic control component 200. In addition, in this embodiment, the partition plate 610 not only serves as a structural partition, but its at least partial spacing with the mounting housing 620 also helps reduce the risk of moisture penetration.

[0244] In this embodiment, by setting an effective gap between the mounting shell 620 and the partition plate 610 and installing the electronic control component 200 on the side away from the partition plate 610, the mounting shell 620 and the partition plate 610 have a double-layer waterproof structure. The double-layer waterproof structure can provide multiple protections and further reduce the intrusion of external moisture or humidity.

[0245] In some embodiments, please refer to Figure 8 and Figure 7 The mounting housing 620 is provided with a mounting groove 620a, which has a groove opening and a first groove wall 621 opposite to the groove opening. The first groove wall 621 extends along a first direction. The first groove wall 621 includes a mounting part 621c and a ventilation part 621d. The circuit board 210 is mounted on the side of the mounting part 621c away from the partition plate 610. The ventilation part 621d is provided with a second vent hole 620b that penetrates the thickness side of the first groove wall 621.

[0246] For example, the ventilation section 621d is the first groove wall 621 in Figure 8 The part highlighted by the dashed line shown is the mounting part 621c. Figure 8 The first groove wall 621 shown is the part other than the part highlighted by the dashed line.

[0247] The technical solution of this embodiment provides more stringent protection by setting a second vent 620b in the part where the circuit board 210 is not provided. This improves the heat dissipation efficiency of the electronic control component 200, reduces the damage of external substances such as moisture and dust to the circuit board 210, and improves the stability and reliability of the heat exchange module 10 in high humidity or harsh environments.

[0248] In some embodiments, please refer to Figure 7 and Figure 8 The mounting portion 621c includes a first mounting section 621a and a second mounting section 621b arranged sequentially along a first direction. The second mounting section 621b extends obliquely from the first mounting section 621a toward the second sidewall 102, and one end of the second mounting section 621b near the second sidewall 102 is biased toward the first receiving cavity 14. In the first direction, the ventilation portion 621d is located between the second mounting section 621b and the first sidewall 101.

[0249] The ventilation section 621d is located between the second mounting section 621b and the first sidewall 101. Because the second mounting section 621b extends at an angle towards the second sidewall 102, this portion forms an effective airflow channel 90, which promotes airflow within the device. In some embodiments, the ventilation section 621d is located on the side of the first mounting section 621a away from the second air outlet 13, further enhancing the waterproofing effect at the second air outlet 13. The angled design of the second mounting section 621b provides a more compact and rational space layout within the device.

[0250] In some embodiments, please refer to Figure 15 and Figure 16 The second receiving cavity 15 is provided with a first air duct plate 410, which divides the second receiving cavity 15 into an electrical control cavity 16 and a heat dissipation cavity 17 arranged sequentially along a first direction. The electrical control assembly 200 includes a circuit board 210 and a heat sink 220. At least a portion of the circuit board 210 is located in the electrical control cavity 16, and the heat sink 220 is connected to the circuit board 210 and located in the heat dissipation cavity 17. The heat dissipation cavity 17 is provided with a first air inlet 11 that communicates with the external space and a first air outlet 12 that communicates with the first receiving cavity 14. The first air inlet 11, the heat dissipation cavity 17 and the first air outlet 12 are sequentially connected to form a first heat dissipation air duct. The first air inlet 11, the heat dissipation cavity 17, the electrical control cavity 16 and the airflow channel 90 are sequentially connected to form a second heat dissipation air duct.

[0251] In some embodiments, the air duct housing 400 further includes a second air duct plate 420, which divides the heat dissipation cavity 17 into an air inlet cavity 18 and an air outlet cavity 19, and the heat sink 220 is disposed in the air outlet cavity 19; the first air duct plate 410 is provided with a first air duct opening 411 connecting the air inlet cavity 18 and the electrical control cavity 16, and the second air duct plate 420 is provided with a second air duct opening 421 connecting the air inlet cavity 18 and the air outlet cavity 19; the opening area of ​​the first air duct opening 411 is smaller than the opening area of ​​the second air duct opening 421.

[0252] As mentioned earlier, the heat sink 220 is mainly used to accelerate the heat dissipation of the heat-generating parts of the circuit board 210. The components in the electronic control cavity 16 generate relatively little heat. The opening area of ​​the first air duct 411 is smaller than the opening area of ​​the second air duct 421, allowing more airflow to enter the exhaust cavity 19 for heat exchange with the heat sink 220, and less airflow to enter the electronic control cavity 16 for heat exchange with the components within the electronic control cavity 16. This allows for effective management of the airflow between the electronic control cavity 16 and the heat dissipation cavity 17. In other words, the ratio of airflow entering the electronic control cavity 16 to entering the exhaust cavity 19 can be controlled by the size of the opening area of ​​the first air duct 411, thereby improving the heat dissipation efficiency of the electronic control component 200. Preferably, the opening area of ​​the first air duct 411 is less than or equal to one-quarter of the opening area of ​​the second air duct 421. For example, the opening area of ​​the first air duct 411 can be one-quarter, one-fifth, one-sixth, or one-tenth of the opening area of ​​the second air duct 421, etc., which will not be listed here.

[0253] In some embodiments, the partition plate 610 is provided with an installation opening 610a, the installation shell 620 passes through the installation opening 610a, the first installation section 621a is located in the second receiving cavity 15, the second installation section 621b is located in the first receiving cavity 14, and a portion of the first baffle plate 300 is located on the side of the second installation section 621b facing the first receiving cavity 14.

[0254] In this embodiment, by arranging the first mounting section 621a and the second mounting section 621b in the second receiving cavity 15 and the first receiving cavity 14 respectively, the internal space of the equipment can be utilized more rationally. Secondly, in this application, the first baffle plate 300 is also located on the side of the second mounting section 621b facing the first receiving cavity 14, which improves the waterproof performance of the second receiving cavity 15 at the second mounting section 621b.

[0255] In some embodiments, the first baffle plate 300 includes a second baffle wall 320 and a third baffle wall 330; the first baffle wall 310, the second baffle wall 320 and the third baffle wall 330 are arranged sequentially along a first direction; the second baffle wall 320 is located on the side of the second mounting section 621b adjacent to the fan 710; the third baffle wall 330 is recessed from the first receiving cavity 14 toward the second receiving cavity 15; the third baffle wall 330 is provided with a first air outlet 12.

[0256] The first water-retaining wall 310, the second water-retaining wall 320, and the third water-retaining wall 330 can be directly connected or connected by a short connecting wall. The first water-retaining wall 310, the second water-retaining wall 320, and the third water-retaining wall 330 are typically integrally formed. Generally, the first water-retaining wall 310, the second water-retaining wall 320, and the third water-retaining wall 330 cover the mounting shell 620. Since the second mounting section 621b of the mounting shell 620 facing the receiving space is an inclined wall along the first direction, in order to reduce the installation space between the first water-retaining plate 300 and the separator 600, the second water-retaining wall 320 is also typically inclined along the first direction. The third water-retaining wall 330 is recessed from the first receiving cavity 14 towards the second receiving cavity 15. In this case, the second water-retaining wall 320 and the third water-retaining wall 330 cooperate with each other, functioning similarly to eaves, effectively guiding the water flow path.

[0257] This embodiment provides a roof-like function through the setting of the second water-blocking wall 320 and the third water-blocking wall 330. The inclined extension of the second water-blocking wall 320 and the recessed setting of the third water-blocking wall 330 effectively guide the water flow path, thereby at least reducing the probability of water flowing into the second receiving cavity 15 through the first air outlet 12, and thus improving the waterproof performance of the second receiving cavity 15.

[0258] In some embodiments, the first baffle plate 300 includes a fourth baffle wall 340, which is located at the end of the third baffle wall 330 away from the second baffle wall 320. The fourth baffle wall 340 is opposite to and spaced apart from the second side wall 102. The fourth baffle wall 340 is provided with a first air outlet 12.

[0259] In this embodiment, a fourth water-blocking wall 340 is further provided. The fourth water-blocking wall 340 is connected to the third water-blocking wall 330 and is provided with a first air outlet 12. By being arranged opposite to and at intervals with the second side wall 102, a reliable air outlet channel is formed. In conjunction with the eaves-like structure of the third water-blocking wall 330, water is effectively prevented from entering the equipment from the direction of the first air outlet 12.

[0260] In this embodiment, the fourth water-blocking wall 340 is located after the third water-blocking wall 330 and is connected to the support plate 131c or the second side plate 131b. In this way, when water droplets on the fan 710 are thrown to the first water-blocking wall 310, the second water-blocking wall 320 and the third water-blocking wall 330, the water droplets flow downward along the first water-blocking plate 300 and reach the fourth water-blocking wall 340. The fourth water-blocking wall 340 is bent and connected to the third water-blocking wall 330, and the water flow is blocked at the connection between the third water-blocking wall 330 and the fourth water-blocking wall 340, which further enhances the waterproof capability of the electronic control component 200.

[0261] In some embodiments, the first baffle plate 300 and the partition plate 610 are metal parts, and the mounting shell 620 is a plastic part.

[0262] The first baffle plate 300 and the partition 600 are made of metal. Metal typically possesses excellent resistance to compression, bending, and impact, helping to withstand external mechanical forces. When used to construct the baffle plate and partition 600, they enhance the stability and sealing of the overall structure. The metal components in the baffle plate prevent deformation in high-temperature and high-humidity environments, maintaining a good sealing effect. The metal partition plate 610 provides robust support for the mounting shell 620 inserted within it, preventing deformation due to external forces from affecting installation accuracy.

[0263] The mounting housing 620 is made of plastic. Compared to metal, plastic is lighter, easier to assemble and maintain, has good insulation properties, and is suitable for applications involving contact with electrical components, improving equipment safety. Furthermore, plastic parts offer high molding flexibility; injection molding can achieve one-piece molding of complex structures, saving production costs. They are also less susceptible to corrosion from moisture, acids, alkalis, and other gases in the environment, making them suitable for outdoor or complex environments. In addition, the mounting housing 620 serves as a support for the electrical control component 200, and using plastic reduces the risk of electric shock.

[0264] The above description is merely an exemplary embodiment of this application and does not limit the scope of protection of this application. Any equivalent structural transformations made based on the technical concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the scope of protection of this application.
