Technical Field

[0001] This application relates to the field of heating, ventilation and air conditioning (HVAC) equipment technology, and more particularly to an HVAC equipment and its outdoor unit. Background Technology

[0002] Heating, ventilation, and air conditioning (HVAC) systems are an important component of building environmental control, encompassing multiple systems such as heating, ventilation, and air conditioning. They are widely used in residential, commercial, and industrial buildings. Their main function is to create a comfortable and healthy living and working environment by regulating parameters such as indoor temperature, humidity, and airflow.

[0003] As a key control component of HVAC equipment, the electrical control box is usually located in the outdoor unit of the HVAC system. The electrical control box typically integrates circuit modules such as the main control module, drive module, and frequency converter module to control the operation of components in the HVAC system (such as compressors and fans).

[0004] However, in related technologies, the electrical control box is usually fixed in the outdoor unit, making its installation position unadjustable. This design limits the adaptability and flexibility of the electrical control box when faced with different installation spaces or conditions. Utility Model Content

[0021] The first positioning structure is one of a positioning hole and a positioning buckle, and the second positioning structure is the other of a positioning hole and a positioning buckle.

[0022] In some embodiments, the housing body has a mounting cavity and an access port communicating with the mounting cavity, and the bracket is disposed at the access port so that the electrical control box is mounted at the access port via the bracket.

[0047] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0048] Heating, ventilation, and air conditioning (HVAC) systems are used to regulate the indoor environment, including functions such as heating, ventilation, and air conditioning. Their main purpose is to provide users with a comfortable and healthy indoor environment by controlling parameters such as temperature, humidity, and airflow. Common HVAC equipment includes air conditioners, radiators, and ventilation systems. These devices are widely used in residential, commercial buildings, and industrial settings.

[0049] Taking HVAC equipment as an example, an air conditioning system can be a multi-split system for buildings, that is, multiple indoor units are connected in parallel relative to one or more outdoor units 100, forming a circulation loop so that the heat exchange medium can circulate.

[0050] Please see Figures 1 to 3 In this embodiment of the application, the outdoor unit 100 includes a housing 1 and an electrical control box 2.

[0051] The housing 1 is the external structure of the outdoor unit 100 of the HVAC equipment. It has a mounting cavity 1a, providing installation space for the internal components of the outdoor unit 100 and protecting them while optimizing airflow. The housing 1 can be made of metal or high-strength plastic, possessing good mechanical strength and corrosion resistance. The housing 1 can be rectangular and placed on the roof or ground. The housing 1 isolates internal electrical components from the outside environment, preventing direct contact by users and reducing the occurrence of safety accidents such as electric shock.

[0052] The housing 1 includes a main body 11 and a bracket 12, with the main body 11 having a mounting cavity 1a. The bracket 12 serves as the mounting component for the electrical control box 2, providing a physical mounting base for the electrical control box 2. The bracket 12 is typically made of metal or high-strength plastic, possessing good mechanical strength and corrosion resistance, preventing damage from impacts and vibrations, thus providing a reliable, stable, and safe mounting position for the electrical control box 2. The bracket 12 is connected to the main body 11, and the connection method between the bracket 12 and the main body 11 includes, but is not limited to, welding and screwing, etc., which are not specifically limited in this application.

[0053] The electrical control box 2 is the core control component of the HVAC equipment, and it is installed inside the mounting cavity 1a. This installation of the electrical control box 2 within the housing 1 facilitates inspection, maintenance, and replacement, and also streamlines the overall installation and layout of the HVAC equipment. The electrical control box 2 is responsible for the precise control of the HVAC equipment's operation. It is equipped with various control circuits, using electronic components and wiring to control the HVAC equipment's start-up, stop, temperature adjustment, mode switching, and other operations.

[0054] Furthermore, the housing 1 provides protection for the electronic components inside the control box 2, preventing dust, moisture, oil, and other external impurities from entering. It also protects the control box 2 from extreme environmental conditions (such as temperature, humidity, and chemical corrosion), ensuring normal operation in various environments and extending the lifespan of the control box 2. The control box 2 contains high-voltage circuits and live components; placing them inside the housing 1 prevents accidental contact by users, reduces the risk of electric shock, and improves safety. The housing 1 also acts as a shield, reducing the impact of external electromagnetic interference on the electronic components inside the control box 2, ensuring the stability and reliability of the control system.

[0055] The electrical control box 2 includes a box body 2a, which is the main structure of the electrical control box 2. The box body 2a contains a receiving cavity 211a. The electrical control box 2 also includes a circuit module (not shown in the figure), which is housed within the receiving cavity 211a. The box body 2a serves to support and protect the internal circuit module, preventing it from shifting or being damaged during use due to external vibration or impact. By using the box body 2a, components such as the circuit module are integrated into a unified structure, which facilitates the overall design and assembly of the electrical control box 2, and makes production and maintenance easier.

[0056] like Figure 6 and Figure 8 As shown, in some embodiments, the box body 2a is provided with a hanging hole 212a, and the bracket 12 is provided with a hook 1211. The hook 1211 and the hanging hole 212a form a hook-and-loop engagement, allowing the electrical control box 2 to be suspended on the bracket 12 through the engagement of the hook 1211 and the hanging hole 212a, thereby being suspended in the mounting cavity 1a. It should be noted that this application does not impose specific limitations on the location of the hanging hole 212a and the hook 1211. In other embodiments, the box body 2a is provided with a hook 1211, and the bracket 12 is provided with a hanging hole 212a. The hook 1211 and the hanging hole 212a form a hook-and-loop engagement, which also allows the electrical control box 2 to be suspended on the bracket 12 through the engagement of the hook 1211 and the hanging hole 212a, thereby being suspended in the mounting cavity 1a. The number of hanging holes 212a can be 2, 3, 4, or other numbers, and this application does not impose specific limitations on this number.

[0057] The hanging hole 212a is elongated, allowing the hook 1211 to move along its length, thereby adjusting the position of the electrical control box 2. This design ensures that the installation position of the electrical control box 2 has a certain adjustment margin, facilitating flexible adjustment of its installation position to adapt to different installation spaces and thus improving its applicability.

[0058] Based on the above-described design, this application provides hooks 1211 or hanging holes 212a on the control box 2 and bracket 12 respectively, allowing the control box 2 to be suspended within the mounting cavity 1a of the outdoor unit 100. Furthermore, by designing the through-hole as an elongated structure, the hooks 1211 can move along the length of the hanging hole 212a, thereby adjusting the position of the control box 2. This design ensures that the installation position of the control box 2 has a certain adjustment margin, facilitating flexible adjustment of its installation position to adapt to different installation spaces and thus improving its applicability.

[0059] like Figure 2 and Figure 3As shown in the embodiment of this application, the housing 1 is in the shape of a cuboid, while the electrical control box 2 has a length direction, which is arranged along the height direction (i.e., the vertical direction) of the housing 1. Therefore, the internal structure of the electrical control box 2 has a vertical arrangement. This vertical length arrangement can better meet the overall structural layout requirements of the equipment when the housing 1 has a large height and limited horizontal space, and is also conducive to heat dissipation and maintenance operations.

[0060] It should be noted that this application is not limited to the arrangement of the control box 2 along the height direction of the housing 1 in the above embodiments. In other embodiments, the control box 2 may also be arranged along the length direction of the housing 1, or the control box 2 may be arranged along the width direction of the housing 1. Furthermore, the control box 2 may not be a single form extending along the length direction; it may also vary according to the internal space of the housing 1, for example, it may be shaped like an "L" or a "T".

[0061] In some embodiments, an air duct is formed within the mounting cavity 1a. This air duct guides air to flow along a predetermined path, preventing disordered airflow within the casing 1 and thus improving heat dissipation efficiency. Additionally, the outdoor unit 100 includes a blower fan disposed within the mounting cavity 1a. The blower fan is located at the top of the casing 1, i.e., at the top of the air duct, and blows air upwards. Furthermore, the electrical control box 2 is located within the air duct, allowing the airflow within the air duct to remove the heat generated by the electrical control box 2, ensuring effective heat dissipation for the electrical control box 2.

[0062] See Figure 2 and Figure 3 The housing 1 also includes a chassis 13, which is connected to the main body 11 and together with the main body 11 forms a mounting cavity 1a. The main body 11 has an inspection port 11a, which communicates with the mounting cavity 1a, facilitating the inspection, maintenance, and replacement of components within the mounting cavity 1a. A bracket 12 is located at the inspection port 11a, allowing the electrical control box 2 to be mounted there. This enables maintenance personnel to quickly access the electrical control box 2 without having to enter the mounting cavity 1a extensively, significantly improving the efficiency of inspection and maintenance. Furthermore, the bracket 12 is positioned relative to the inspection port 11a within the mounting cavity 1a, meaning there is a certain distance between the bracket 12 and the plane containing the inspection port 11a. This facilitates the mounting of the electrical control box 2 within the mounting cavity 1a without obstructing the sealing of the inspection port 11a.

[0063] See Figure 1In some embodiments, the housing 1 also includes an access door 14, which is used to cover the access port 11a to prevent dust, impurities and the like from entering the mounting cavity 1a through the access port 11a, thereby further improving the safety of the internal components of the outdoor unit 100.

[0064] Specifically, in some embodiments, the access door 14 is rotatably connected to the housing body 11, allowing maintenance personnel to expose the access port 11a by opening the access door 14. The access door 14 can be rotatably connected to the housing body 11 via hinges, pivots, or other components; this application does not impose specific limitations on this. Alternatively, in other embodiments, the access door 14 is detachably connected to the housing body 11, allowing maintenance personnel to separate the access door 14 from the housing body 11 by disassembling it, thereby exposing the access port 11a. The access door 14 can be fixedly connected to the housing body 11 via bolted connections, allowing maintenance personnel to separate the access door 14 from the housing body 11 by removing the bolted connections, thus exposing the access port 11a. This application does not impose specific limitations on the manner in which the access port 11a is exposed.

[0065] Please see Figure 4 In some embodiments, the housing 2a includes a heat dissipation structure 21. The heat dissipation structure 21 serves as the main structure of the electrical control box 2, and its interior contains a receiving cavity 211a. The circuit modules are housed within the receiving cavity 211a. Therefore, the heat dissipation structure 21 serves to support, install, and protect the internal circuit modules, preventing them from shifting or being damaged due to external vibrations or impacts during use. The heat dissipation structure 21 can be made of a material with good thermal conductivity, such as aluminum alloy. By integrating the circuit modules into a unified heat dissipation structure 21, the overall design and assembly of the electrical control box 2 can be achieved, facilitating production and maintenance. Furthermore, the heat dissipation structure 21 helps to conduct the heat generated by the circuit modules, improving heat dissipation efficiency.

[0066] In some embodiments, see Figure 5 The heat dissipation structure 21 includes a heat dissipation base 211, which serves as the main body of the heat dissipation structure 21 and provides mounting space for the circuit modules. The heat dissipation base 211 is a shell structure with a certain thickness and has a first side and a second side, namely the front and rear sides of the heat dissipation base 211 along its thickness direction. The housing 2a also includes a first cover 22 and a second cover 23. The first cover 22 is connected to the first side of the heat dissipation base 211 and forms a first cavity 211a1 with the heat dissipation base 211; the second cover 23 is connected to the second side of the heat dissipation base 211 and forms a second cavity 211a2 with the heat dissipation base 211. The first cover 22 and the second cover 23, through their tight fit with the heat dissipation base 211, can effectively prevent external contaminants such as dust and moisture from entering the interior of the first cavity 211a1 and the second cavity 211a2, protecting the internal circuit modules.

[0067] Understandably, the first cavity 211a1 and the second cavity 211a2 are arranged at intervals relative to each other in the thickness direction of the heat dissipation substrate 211, that is, a portion of the heat dissipation substrate 211 separates the first cavity 211a1 and the second cavity 211a2, and the first cavity 211a1 and the second cavity 211a2 are respectively arranged on both sides of the thickness direction of the heat dissipation substrate 211. By setting the first cavity 211a1 and the second cavity 211a2, the partitioned layout of different functional modules is realized. For example, circuit modules with different functions can be arranged in the first cavity 211a1 and the second cavity 211a2.

[0068] The heat dissipation substrate 211 can serve as part of the cavity wall that forms the first cavity 211a1 and the second cavity 211a2, thereby more effectively conducting the heat dissipated by the circuit modules installed in the first cavity 211a1 and the second cavity 211a2, increasing the heat exchange area, improving heat dissipation efficiency, and ensuring that the internal circuit modules remain stable under high load operation.

[0069] Furthermore, the heat dissipation substrate 211 is used as part of the cavity wall of the first cavity 211a1 and the second cavity 211a2. That is, the heat dissipation substrate 211 directly participates in the formation of the outer wall of the electronic control box 2. In this way, the electronic control box 2 is located in the air duct, and the airflow in the air duct can quickly flow through the outer wall of the electronic control box 2, thereby fully exchanging heat. This can more quickly release the heat generated by the electronic control box 2 and further improve the heat dissipation performance.

[0070] See Figure 5 In some embodiments, the heat dissipation substrate 211 includes a cold plate 2111 and a surrounding plate 2112. The cold plate 2111 has a plate-like structure, and the surrounding plate 2112 is connected to the cold plate 2111, and the two are integrated. The surrounding plate 2112 and the cold plate 2111 cooperate to form a receiving cavity 211a, which is used to house the internal circuit modules of the electrical control box 2. The integrated heat dissipation structure 21 enhances the overall strength and durability, and reduces the risk of damage caused by vibration or impact.

[0071] In addition, the electrical control box 2 also includes a flow channel tube, which is mounted on the cold plate 2111 and is integrally formed with the cold plate 2111. Specifically, it can be integrally formed by die casting. The flow channel tube is used to connect the circulation loop and to supply the heat exchange medium. The heat exchange medium flowing in the flow channel tube can remove the heat dissipated by the electrical control box 2 during operation, and dissipate heat from the electronic components inside the electrical control box 2, thereby maintaining the internal temperature of the electrical control box 2 within a reasonable range.

[0072] The enclosure 2112 includes a first enclosure 2112a, which is located on the first side. A first cover 22 is placed on the first enclosure 2112a and is sealed to the side of the first enclosure 2112a away from the cold plate 2111 to form a first cavity 211a1. This sealed fit can effectively prevent dust and moisture from entering and protect the internal circuit module.

[0073] In some implementations, such as Figure 5 As shown, the second cover 23 is a cover with thickness. The side of the second cover 23 near the main body of the cold plate 2111 has a cavity formed along its thickness direction. The second cover 23 seals and covers the side of the cold plate 2111 facing away from the first enclosure 2112a to form the second cavity 211a2. Since the second cover 23 directly seals and covers the side of the cold plate 2111 facing away from the first enclosure 2112a, there is no need to set up an additional enclosure 2112. The process is simpler, which can improve production efficiency and reduce manufacturing costs.

[0074] In an alternative embodiment, the heat dissipation structure 21 also includes a second enclosure (not shown in the figure), which is also integrally formed with the cold plate 2111, significantly enhancing the integrity and stability of the heat dissipation structure 21. This design makes the heat dissipation structure 21 more robust and better able to withstand the heat generated by the internal circuit modules and external mechanical pressure. The second enclosure is connected to the side of the cold plate 2111 facing away from the first enclosure 2112a, and the second cover 23 is sealed to the side of the second enclosure away from the main body of the cold plate 2111 to form a second cavity 211a2, which can better seal the second cavity 211a2, preventing external impurities such as dust and moisture from entering and improving the protection level of the electrical control box 2.

[0075] In some embodiments, the circuit module includes a first circuit module and a second circuit module. The first circuit module is disposed within a first cavity 211a1, and the second circuit module is disposed within a second cavity 211a2. The thickness direction of the first and second circuit modules is consistent with the thickness direction of the heat dissipation substrate 211. When viewed from the thickness direction of the heat dissipation substrate 211 (i.e., from one side to the other), the first and second circuit modules are arranged sequentially along the thickness direction of the heat dissipation substrate 211, rather than being placed horizontally or obliquely. This layout not only allows the first and second circuit modules to make full use of the space in the thickness direction of the heat dissipation substrate 211, making reasonable use of the internal space of the control box 2 and making the overall structure more compact; it also allows the heat dissipation substrate 211 to effectively conduct the heat dissipated by the circuit modules installed in the first cavity 211a1 and the second cavity 211a2, increasing the heat exchange area, improving heat dissipation efficiency, and ensuring that the circuit modules remain stable under high load operation.

[0076] Since the heat generation and heat dissipation requirements of the first circuit module and the second circuit module may be different, by placing them in separate cavities, customized designs can be made according to the specific heat dissipation requirements of the first circuit module and the second circuit module. This also effectively avoids heat cross-interference between the first circuit module and the second circuit module, ensures that the first circuit module and the second circuit module each have a better matching heat dissipation settings, improves the heat dissipation efficiency of the entire electrical control box 2, and optimizes the heat dissipation performance.

[0077] In some embodiments, the first circuit module is a driver board, which is typically used to implement the main functions of the electronic control box 2, such as control and driving. In this embodiment, the driver board is located inside the first cavity 211a1 and is responsible for processing high-voltage signals. The second circuit module is a filter board, which is used to filter the signal, remove noise and interference, and ensure the purity of the signal. In this embodiment, the filter board is located inside the second cavity 211a2 and is responsible for processing low-voltage signals.

[0078] The driver board and filter board are located in separate cavities and are electrically connected. They are partially isolated by a heat dissipation substrate 211, which effectively reduces signal interference between them. In the electrical control box 2, signal interference is a major cause of equipment instability and malfunctions. The cavity design significantly reduces this interference, improving the reliability of the electrical control box 2. Furthermore, it allows for clearer functional division within the electrical control box 2, facilitating management and maintenance. When maintenance or repair of a particular circuit module is required, the problem can be located more quickly, minimizing the impact on other circuit modules and improving maintenance efficiency.

[0079] In some embodiments, the control box 2 further includes a third circuit module (not shown) and a third cover 24. The third cover 24 cooperates with the heat dissipation substrate 211 to form a third cavity 211a3, meeting the sealing requirements of the control box 2. The sealed design can prevent external factors such as dust and moisture from affecting the internal components of the third cavity 211a3, improving the reliability and service life of the control box 2. The third circuit module is located inside the third cavity 211a3. The third circuit module can be an independent control unit or functional module, working in conjunction with the drive board and filter board. By setting the third cavity 211a3 and the third circuit module, the control box 2 achieves a modular arrangement of circuit modules. Each cavity can be designed and installed independently, facilitating the integration and expansion of different functional modules, and reducing the complexity of installation and maintenance.

[0080] See Figure 5The heat dissipation structure 21 also includes a third enclosure plate 2112b, which is connected to the cold plate 2111 and the two are integrated. Through die casting, the cold plate 2111 and the third enclosure plate 2112b can be integrally formed, reducing assembly steps and improving production efficiency. The integrated heat dissipation structure 21 enhances the overall strength and durability, reducing the risk of damage due to vibration or impact. The third cover 24 is sealed to the side of the third enclosure plate 2112b away from the cold plate 2111 to form a third cavity 211a3. This sealing effectively prevents dust and moisture from entering, protecting the internal third circuit module.

[0081] Although the third circuit module inside the third cavity 211a3 also generates heat during operation, its heat dissipation requirements are relatively low. Therefore, the heat dissipation requirements of the third cavity 211a3 are not high, and the efficiency of radiative heat dissipation can be increased by coating the inner surface of the third cavity 211a3 with a coating of high emissivity.

[0082] In this embodiment, the electrical control box 2 further includes a power terminal block (not shown in the figure). The power terminal block can be installed vertically between the first cavity 211a1 and the second cavity 211a2, that is, the power terminal block is located at the bottom of the box 2a. In this way, while achieving electrical connection between the filter board and the drive board, the wiring between the power terminal block and the filter board is also more convenient, without requiring additional external space for the electrical control box 2.

[0083] Additionally, see Figure 4 The electrical control box 2 also includes a terminal block protective shell 25. The terminal block protective shell 25 is connected to the heat dissipation structure 21 and is located on the side of the first cavity 211a1 away from the third cavity 211a3. In this embodiment, the third cavity 211a3, the first cavity 211a1, and the terminal block protective shell 25 are arranged sequentially along the length of the electrical control box 2, which is set vertically. Therefore, the terminal block protective shell 25 is located below the first cavity 211a1. The main function of the terminal block protective shell 25 is to provide additional protection for part of the power terminal block structure. Understandably, the part of the power terminal block that penetrates into the second cavity 211a2 is covered and protected by the second cover 23, which can prevent damage to the power terminal block from the external environment (such as dust, moisture, mechanical impact, etc.), providing a relatively protected environment and reducing the risk of electrical failures caused by external factors. Furthermore, the terminal block protective shell 25 makes the maintenance and inspection of the power terminal block more convenient, without the need to disassemble the entire electrical control box 2.

[0084] like Figure 4As shown, the terminal block protective housing 25 includes a first protective half-shell 251 and a second protective half-shell 252 that overlap each other. The first protective half-shell 251 and the second protective half-shell 252 can be firmly connected by fastening screws. The second protective half-shell 252 is then connected to the heat dissipation structure 21 by fastening screws. The first protective half-shell 251 is located on the front side along the thickness direction of the housing 2a, while the second protective half-shell 252 is located on the rear side along the thickness direction of the housing 2a. That is, compared to the first protective half-shell 251, the second protective half-shell 252 is located closer to the heat dissipation structure 21. The first protective half-shell 251 and the second protective half-shell 252 together enclose a protective cavity 25a, which is the internal space of the terminal block protective housing 25 and is used to accommodate part of the power terminal block.

[0085] like Figure 4 As shown, in some embodiments, the bottom of the terminal block protective housing 25 is provided with a power cord outlet 25b, which is defined by the first protective half-shell 251 and the second protective half-shell 252, so that the power cord can be directly led out from the bottom of the terminal block protective housing 25, avoiding the messy arrangement of the power cord inside the protective housing, and making the wiring neater and more beautiful.

[0086] Specifically, the chassis 13 is provided with a cable pass-through port (not shown in the figure) that opens upwards. The box 2a is located above the cable pass-through port, and the power cord outlet 25b of the control box 2 is arranged opposite to the cable pass-through port in the vertical direction to shorten the distance between the power cord and the power terminal block. The power cord can directly enter the power terminal block inside the box 2a from the cable pass-through port of the chassis 13, avoiding the circuitous wiring of the power cord inside the casing 1, making the wiring operation more convenient.

[0087] In this embodiment, a locking structure 3 is further provided between the bracket 12 and the box 2a. The locking structure 3 is used to fix the electrical control box 2 to prevent the electrical control box 2 from shaking within the mounting cavity 1a. On the one hand, this avoids the problem of the hook 1211 coming out of the hanging hole 212a due to the shaking of the electrical control box 2, causing the electrical control box 2 to fall, thus improving the stability and reliability of the installation and thereby improving the safety of the electrical control box 2. On the other hand, it also avoids the problem of the electrical control box 2 shaking and hitting other internal components, preventing other internal components from being impacted, thereby improving the safety of the internal components of the outdoor unit 100.

[0088] See Figure 6 and Figure 8In some embodiments, the bracket 12 includes a crossbeam 121 connected to the housing body 11 and extending horizontally within the mounting cavity 1a. The crossbeam 121 has a hanging hole 212a. The heat dissipation structure 21 also includes a suspension part 212 connected to the top of the third enclosure plate 2112b, and the suspension part 212 has a hook 1211. This arrangement brings the suspension part 212 closer to the crossbeam 121, facilitating connection between them. This configuration provides the crossbeam 121 with a mounting base for the electrical control box 2. The hanging hole 212a is a perforated structure formed in the suspension part 212, and the hook 1211 is a flip-hook structure on the crossbeam 121. This facilitates the fabrication of the hanging hole 212a and the hook 1211, improving manufacturing efficiency. Furthermore, anti-slip serrations can be provided on the inner side of the hook 1211 to increase friction and further prevent the electrical control box 2 from shaking.

[0089] The suspension part 212 and the third enclosure plate 2112b are integrally formed, meaning the suspension part 212 and the heat dissipation base 211 are also integrally formed. This configuration, on the one hand, enhances the connection strength between the suspension part 212 and the heat dissipation base 211, preventing the suspension part 212 from detaching from the heat dissipation base 211 and avoiding the problem of the control box 2 falling due to the suspension part 212 falling off, thus improving the safety of the control box 2; on the other hand, the integrally formed structure eliminates the need for structures such as the mounting bracket 12 for the suspension part 212 to be assembled on the heat dissipation base 211, reducing the number of parts, improving production efficiency, and helping to reduce production costs. The integral forming method can be integral die casting.

[0090] In some embodiments, the locking structure 3 includes a first fastener 31, a first connecting hole 32, and a second connecting hole 33. The first connecting hole 32 is disposed on the crossbeam 121, and the second connecting hole 33 is disposed on the suspension portion 212. The first fastener 31 can pass through the first connecting hole 32 and the second connecting hole 33 to securely connect the suspension portion 212 to the crossbeam 121. The first connecting hole 32 is an elongated hole along the length of the hanging hole 212a, and the second connecting hole 33 is a round hole. This avoids the problem that the first connecting hole 32 cannot connect with the second connecting hole 33 after adjusting the installation position of the electrical control box 2. Therefore, the locking structure 3 can fix the electrical control box 2 regardless of its installation position, improving the versatility and ease of use of the locking structure 3. In this case, a connecting washer can be provided on the side of the crossbeam 121 away from the suspension portion 212. The first fastener 31 is then secured after passing through the second connecting hole 33, the first connecting hole 32, and the connecting washer in sequence. This improves the connection strength and stability of the locking structure 3. The first fastener 31 can be a screw, snap-fit, etc., and this application does not impose specific limitations on it.

[0091] It is understood that the arrangement of the first connecting hole 32 and the second connecting hole 33 in this application is not fixed. For example, in some embodiments, the second connecting hole 33 is an elongated hole along the length of the hanging hole 212a, and the first connecting hole 32 is a round hole. This avoids the problem that the first connecting hole 32 cannot connect with the second connecting hole 33 after adjusting the installation position of the electrical control box 2. Thus, the locking structure 3 can fix the electrical control box 2 regardless of its installation position, improving the versatility of the locking structure 3 and making it easier to use. In this case, a connecting gasket can be provided on the side of the suspension part 212 away from the crossbeam 121. The first fastener 31 passes through the first connecting hole 32, the second connecting hole 33, and the connecting gasket in sequence before locking. This improves the connection firmness and stability of the locking structure 3.

[0092] Alternatively, in another embodiment, the first connecting hole 32 consists of multiple round holes spaced apart along the length of the hanging hole 212a, and the second connecting hole 33 is a round hole. This ensures that after adjusting the installation position of the control box 2, there is always a corresponding first connecting hole 32 and second connecting hole 33, thus allowing the locking structure 3 to fix the control box 2 regardless of its installation position, improving the versatility of the locking structure 3. In this case, after adjusting the installation position of the control box 2, the first fastener 31 passes through the second connecting hole 33 and the corresponding first connecting hole 32 in sequence before locking. Alternatively, in another embodiment, the second connecting hole 33 consists of multiple round holes spaced apart along the length of the hanging hole 212a, and the first connecting hole 32 is a round hole. In this case, after adjusting the installation position of the control box 2, the first fastener 31 passes through the first connecting hole 32 and the corresponding second connecting hole 33 in sequence before locking.

[0093] In this embodiment, a limiting structure 4 is further provided between the bracket 12 and the box 2a. The limiting structure 4 is used to limit the installation position of the electrical control box 2, thereby effectively limiting the electrical control box 2. On the one hand, it can restrict the electrical control box 2 to the installation position, preventing the electrical control box 2 from shaking, thereby avoiding the problem of the hook 1211 falling out of the hanging hole 212a due to the shaking of the electrical control box 2, improving the stability and reliability of the installation, and thus improving the safety of the electrical control box 2; on the other hand, it can also prevent the electrical control box 2 from shaking and hitting other internal components, preventing other internal components from being impacted, thereby improving the safety of the internal components of the outdoor unit 100.

[0094] See Figure 7 and Figure 9In some embodiments, the bracket 12 includes a column 122 connected to the housing body 11 and extending vertically within the mounting cavity 1a. The heat dissipation structure 21 also includes a connecting ear 213 connected to the side of the first enclosure plate 2112a. This allows the connecting ear 213 to be positioned closer to the column 122, facilitating connection between the connecting ear 213 and the column 122. The limiting structure 4 includes a second fastener 41, a first limiting hole 42, and a second limiting hole 43; the first limiting hole 42 is located on the column 122, and the second limiting hole 43 is located on the connecting ear 213. The second fastener 41 can pass through the first limiting hole 42 and the second limiting hole 43 to securely connect the connecting ear 213 to the column 122. With this configuration, after the control box 2 is positioned, the limiting structure 4 limits the control box 2, further preventing it from shaking and improving its safety and reliability. The second fastener 41 can be a screw, a snap-fit, etc., and this application does not impose specific restrictions on it.

[0095] The connecting ear 213 is integrally formed with the first enclosure plate 2112a, that is, the connecting ear 213 is integrally formed with the heat dissipation base 211. This can improve the connection strength between the connecting ear 213 and the heat dissipation base 211, prevent the connecting ear 213 from detaching from the heat dissipation base 211, avoid the problem of the control box 2 shaking or shifting due to connection failure, and improve the safety of the control box 2.

[0096] See Figure 7 and Figure 9 In this embodiment, the outdoor unit 100 further includes an adapter plate 5, which is disposed between the connecting ear 213 and the column 122 to connect the connecting ear 213 and the column 122 respectively. Specifically, the adapter plate 5 is provided with a first adapter hole 51 and a second adapter hole 52, the first adapter hole 51 corresponding to the first limiting hole 42, and the second adapter hole 52 corresponding to the second limiting hole 43. In some embodiments, a second fastener 41 passes through the first adapter hole 51 and the first limiting hole 42 to fix the adapter plate 5 to the column 122, and the second fastener 41 also passes through the second adapter hole 52 and the second limiting hole 43 to fix the adapter plate 5 to the connecting ear 213. In this way, the connecting ear 213 and the column 122 are fixed by the adapter plate 5, thereby limiting the electrical control box 2 to the installation position. Understandably, this application does not impose specific limitations on the size of the adapter plate 5. After the electrical control box 2 is locked in place, those skilled in the art can select an adapter plate 5 of appropriate size based on the distance between the connecting ear 213 and the column 122 to connect the connecting ear 213 and the column 122. This arrangement ensures that the limiting structure 4 can limit the electrical control box 2 regardless of its installation position, improving the versatility of the limiting structure 4 and facilitating its use.

[0097] See Figure 7 and Figure 9 In some embodiments, the connecting ear 213 is provided with a first positioning structure 2131, and the adapter plate 5 is provided with a second positioning structure 53. The first positioning structure 2131 is a positioning hole, and the second positioning structure 53 is a positioning buckle. The positioning hole and the positioning buckle engage to quickly position the connection between the adapter plate 5 and the connecting ear 213. This allows the second adapter hole 52 on the adapter plate 5 to quickly align with the second limiting hole 43 on the connecting ear 213, improving connection efficiency and effectively shortening installation time. This application does not specifically limit the type of the first positioning mechanism and the second positioning structure 53; the first positioning structure 2131 can also be a positioning buckle, and the second positioning structure 53 can also be a positioning hole.
