air conditioner outdoor unit

[0001] Cross-reference to related applications

[0002] This application claims priority to Chinese patent applications filed on December 17, 2024, No. 2024231219137, 2024, 2024231217381, 2024231220933, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of air conditioning equipment technology, and in particular to an outdoor air conditioning unit. Background Technology

[0004] When handling larger cooling or heating loads, or when improving the energy efficiency of refrigeration systems, air conditioner outdoor units, such as those in four-pipe air conditioning systems, often use heat exchangers with larger volumes and larger heat exchange areas.

[0005] However, installing such large-sized heat exchangers presents a series of challenges. For example, the limited space available for outdoor air conditioning units makes it difficult to install such large heat exchangers. Outdoor air conditioning units compatible with large heat exchangers often require longer piping and more cables, increasing the complexity of the piping layout. This complexity further reduces the installation space available for the heat exchanger. The outdoor air conditioning unit needs to ensure sufficient space and ventilation around the heat exchanger to avoid reduced heat exchange efficiency due to wind resistance; therefore, this requires reserving a reasonable ventilation area within the limited space.

[0006] A shut-off valve is typically installed between the high-pressure and low-pressure sides of a refrigeration cycle to control the flow of refrigerant within the cycle. For ease of installation and management, shut-off valves are usually installed in the outdoor unit.

[0007] Furthermore, shut-off valves are typically mounted on a valve plate, which forms a stable platform to firmly support and ensure that the shut-off valve will not loosen or shift during use. Traditional shut-off valve mounting structures are generally only suitable for ordinary two-pipe refrigeration cycles, and not for three-pipe or four-pipe refrigeration cycles. Using multiple similar traditional shut-off valve structures would increase the size of the outdoor unit.

[0008] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Summary of the Invention

The refrigeration cycle may include a series of processes such as compression, condensation, expansion, and evaporation to cool or heat an indoor space.

[0102] Low-temperature, low-pressure refrigerant can enter compressor 11, which compresses the refrigerant into a high-temperature, high-pressure refrigerant gas and discharges the compressed refrigerant gas. The discharged refrigerant gas can flow into the condenser. The condenser can condense the compressed refrigerant into a liquid refrigerant, and heat can be released to the surrounding environment through the condensation process.

[0103] A throttling element (e.g., an electronic expansion valve) expands the high-temperature, high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the refrigerant that has expanded in the electronic expansion valve and returns the low-temperature, low-pressure refrigerant gas to the compressor 11. The evaporator achieves a cooling effect by utilizing the latent heat of refrigerant evaporation to exchange heat with the material being cooled. Throughout the cycle, the air conditioning system regulates the temperature of the indoor space.

[0104] An air conditioner outdoor unit can refer to the part of the refrigeration cycle that includes the compressor 11 and the outdoor heat exchanger. The indoor unit of an air conditioner may include an indoor heat exchanger, and an electronic expansion valve may be installed in either the indoor or outdoor unit.

[0105] The indoor and outdoor heat exchangers can be used as condensers or evaporators. When the indoor heat exchanger is used as a condenser, the air conditioner can be used as a heater in heating mode; when the indoor heat exchanger is used as an evaporator, the air conditioner can be used as a cooler in cooling mode.

[0106] An outdoor unit for an air conditioner may include: an outer casing, which is generally rectangular box-shaped. The casing may be made of steel sheet (e.g., galvanized steel sheet) or other metal materials and may have corrosion resistance, durability, and sufficient strength. The casing serves to protect the internal components from external environmental factors (e.g., wind, rain, dust, etc.) and prevent airborne impurities (e.g., leaves) from entering the casing, thereby ensuring the long-term stable operation of the outdoor unit.

[0107] In some embodiments of this application, the outer casing may be provided with ventilation holes, grilles, or heat sinks to ensure that the outdoor heat exchanger 10 installed therein can achieve ideal heat dissipation efficiency. The bottom of the outer casing may be provided with a bracket or mounting holes for fixing the outdoor unit of the air conditioner to a wall, platform, or other bracket to ensure stable installation and that the outer casing can withstand the vibration of the outdoor unit during operation.

[0108] An installation cavity 12 can be formed inside the outer casing. Components such as the compressor 11, outdoor heat exchanger 10, outdoor fan, shut-off valve 27, and piping can all be installed in the installation cavity 12.

[0109] The housing may include a base plate 14. In some embodiments of this application, the housing may also include a top plate, two side plates, a front plate, and a rear plate. These plate-like components together form a mounting cavity 12 within the housing. In some embodiments of this application, the base plate 14 may be a generally rectangular metal plate-like component, constituting the bottom portion of the mounting cavity 12. The compressor 11 may be mounted on the base plate 14. The base plate 14 provides support for the compressor 11 and also serves to protect and absorb shock. In the following description, unless otherwise specified, the front view shown in FIG2 is used as a reference, where "up" and "down" refer to the direction in the height direction of the housing, "left" and "right" refer to the direction in the length direction of the housing, and "front" and "rear" refer to the direction in the width direction of the housing. In other words, in this application, the height direction may also be referred to as the vertical direction of the housing, the length direction may also be referred to as the length direction of the housing, and the width direction may also be referred to as the front-back direction of the housing.

[0110] In some embodiments of this application, the compressor 11 may be installed in the central area of ​​the base plate 14, and the compressor 11 may be fixedly connected to the base plate 14 to avoid vibration or displacement during operation.

[0111] In some embodiments of this application, the outdoor heat exchanger 10 may be mounted on the base plate 14 and close to the side surface of the base plate 14, thereby enabling the outdoor heat exchanger 10 to perform efficient heat exchange with the outside air.

[0112] A shut-off valve 27 may also be installed in the housing. The shut-off valve 27 can be installed between the high-pressure side and the low-pressure side of the refrigeration cycle to control the flow of refrigerant.

[0113] In some embodiments of this application, the number of shut-off valves 27 in the housing may be two. The layout of the shut-off valves 27 can be matched with a two-pipe refrigeration cycle. A two-pipe refrigeration cycle is the most common air conditioning piping configuration, where the outdoor unit and indoor unit are connected via liquid-side piping and gas-side piping. Correspondingly, the shut-off valves 27 may include a liquid-side shut-off valve 27 and a gas-side shut-off valve 27. The liquid-side shut-off valve 27 may be located on the liquid-side piping, and the gas-side shut-off valve 27 may be located on the gas-side piping.

[0114] In some embodiments of this application, to increase flexibility, the outdoor unit and indoor unit of the air conditioner can be connected by three pipes. The layout of the shut-off valves 27 can be matched with the three-pipe refrigeration cycle, and a corresponding shut-off valve 27 can be installed on each pipe. The three-pipe refrigeration cycle can be used in environments requiring both cooling and heating, and can simultaneously meet both cooling and heating needs.

[0115] In some embodiments of this application, to cope with more complex usage environments, the outdoor unit and indoor unit of the air conditioner can be connected by four pipes. The layout of the shut-off valves 27 can be matched with the refrigeration cycle of the four-pipe air conditioning system, and a corresponding shut-off valve 27 can be installed on each pipe. The refrigeration cycle of the four-pipe air conditioning system can simultaneously achieve cooling and heating, and can also ensure that the cooling and heating needs of different areas are met simultaneously.

[0116] In some embodiments of this application, the shut-off valve 27 may include a valve body. A generally cross-shaped flow channel is formed in the valve body of the shut-off valve 27. A first interface 28 is formed at the lower end of the valve body. The first interface 28 can be used for fluid connection with a refrigerant piping (also referred to as a refrigerant line) near the indoor unit. A second interface 29 may be formed at the rear end of the valve body. The second interface 29 can be used for fluid connection with a refrigerant piping (also referred to as a refrigerant line) on the outdoor unit side. A maintenance end 31 may be provided at the upper end of the valve body. The maintenance end 31 can be sealed by a removable valve cover. An operating end 30 may be provided at the front end of the valve body. The operating end 30 may be provided with a removable nut. When necessary operation is required to drive the valve core of the valve body, the nut of the operating end 30 can be removed. A fixing part may also be provided on the valve body, which may be configured as flanges 32 on both sides of the valve body, and the fixing part may extend outward from the valve body, as shown in FIG7.

[0117] As shown in Figures 1 to 8, in some embodiments of this application, the outdoor unit of the air conditioner may further include a mounting assembly 13. The mounting assembly 13 may be disposed within the mounting cavity 12 of the housing and may be mounted on the base plate 14. A shut-off valve 27 may be mounted on the mounting assembly 13. The mounting assembly 13 serves to support and secure the shut-off valve 27, preventing it from moving or loosening during use or transportation, while also facilitating disassembly and installation of the shut-off valve 27 by operators. The mounting assembly 13 also provides a degree of protection against damage to the shut-off valve 27 from external impacts.

[0118] In some embodiments of this application, as shown in FIG3, the mounting assembly 13 may include a first mounting element 15 and a second mounting element 16 disposed independently of each other. The first mounting element 15 may be used to support and secure at least one shut-off valve 27. The second mounting element 16 may be used to support and secure one or more shut-off valves 27. The second mounting element 16 may be disposed on the base plate 14. The first mounting element 15 and the second mounting element 16 may be disposed sequentially from top to bottom along the height direction of the housing. The first mounting element 15 is detachably disposed above the second mounting element 16.

[0119] In some embodiments of this application, the first mounting element 15 can be a generally plate-shaped component, and the second mounting element 16 can also be a generally plate-shaped component; the first mounting element 15 and the second mounting element 16 can be used in conjunction, as shown in FIG5. The first mounting element 15 and the second mounting element 16 themselves can have sufficient thickness to support the weight of the shut-off valve 27 and the vibration of the shut-off valve 27 during operation.

[0120] In some embodiments of this application, the second mounting element 16 may be used alone.

[0121] In some embodiments of this application, the first mounting element 15 can be a bracket, and the second mounting element 16 can also be a bracket; the first mounting element 15 and the second mounting element 16 can be used in conjunction. Alternatively, the second mounting element 16 can also be used alone.

[0122] In some embodiments of this application, the first mounting element 15 and the second mounting element 16 may be made of corrosion-resistant, high-strength metal materials, such as galvanized steel sheet or stainless steel, so that the first mounting element 15 and the second mounting element 16 can withstand the pressure and temperature changes in the air conditioning system.

[0123] The following description will refer to Figures 5 and 6, using the plate-shaped first mounting element 15 and second mounting element 16 as examples.

[0124] The first mounting element 15 and the second mounting element 16 may extend in a direction substantially parallel to the length direction.

[0125] In some embodiments of this application, the second mounting element 16 may include a main mounting portion 17. The main mounting portion 17 may be located generally above the second mounting element 16, for example, at the upper edge of the second mounting element 16. A plurality of shut-off valves 27 may be mounted via the main mounting portion 17, and the plurality of shut-off valves 27 may be arranged along the same direction, for example, along the length direction.

[0126] In some embodiments of this application, in the width direction or front-back direction of the housing, one refrigerant port of the shut-off valve 27 may be located on one side of the second mounting element 16, and the other refrigerant port may be located on the other side of the second mounting element 16. For example, the first port 28 of the shut-off valve 27 connected to the refrigerant piping (also referred to as the refrigerant line) near the indoor unit side may be located on the front side of the second mounting element 16, and the second port 29 of the shut-off valve 27 connected to the refrigerant piping (also referred to as the refrigerant line) near the outdoor unit side may be located on the rear side of the second mounting element 16, as shown in FIG7. In this way, the operating end 30 can be located in a relatively forward position in the housing of the outdoor unit of the air conditioner, extending relative to the second mounting element 16, for easy operation. That is, the shut-off valve 27 can be mounted on the second mounting element 16 with the operating end 30 extending forward relative to the second mounting element 16 and the second port 29 connected to the refrigerant piping (also referred to as the refrigerant line) near the outdoor unit side penetrating through the second mounting element 16.

[0127] In some embodiments of this application, as shown in Figures 6 and 7, the main mounting portion 17 may include a plurality of main mounting notches 18. The plurality of main mounting notches 18 may be arranged along the length direction. Each main mounting notch 18 may correspond to a shut-off valve 27. The main mounting notches 18 may be generally U-shaped. The opening of the U-shaped main mounting notch 18 may be formed on the upper part of the second mounting element 16, for example, at the upper edge of the second mounting element 16. Alternatively, the main mounting notch 18 may be formed as part of the upper edge of the second mounting element 16.

[0128] In some embodiments of this application, the bottom heights of the plurality of main mounting notches 18 may be the same as each other.

[0129] In some embodiments of this application, the bottom heights of the plurality of main mounting notches 18 may be different from each other.

[0130] In some embodiments of this application, the bottom curvature of the plurality of main mounting notches 18 may be the same as that of each other.

[0131] In some embodiments of this application, the bottom curvature of the plurality of main mounting notches 18 may be different from each other.

[0132] In some embodiments of this application, the widths of the plurality of main mounting notches 18 may be the same as each other.

[0133] In some embodiments of this application, the widths of the plurality of main mounting notches 18 may be different from each other.

[0134] In some embodiments of this application, the main mounting portion 17 may also be provided with main fixing holes on both sides corresponding to the main mounting notch 18. Fasteners such as bolts can pass through the fixing portion and the main fixing holes on the valve body in sequence, thereby fixing the shut-off valve 27 at a predetermined position in the main mounting notch 18.

[0135] In some embodiments of this application, the main mounting part 17 may be equipped with three shut-off valves 27, and the three shut-off valves 27 may be arranged along the length direction.

[0136] In some embodiments of this application, the main mounting portion 17 may include three main mounting notches 18. The three main mounting notches 18 may be arranged along the length direction. Each main mounting notch 18 may be correspondingly provided with a shut-off valve 27. The main mounting notches 18 are generally U-shaped, and the opening of the U-shaped main mounting notch 18 may be formed at the upper edge of the second mounting element 16.

[0137] In some embodiments of this application, the height of two of the plurality of main mounting notches 18 may be the same as that of each other, and the height of another of the plurality of main mounting notches 18 may be different from the height of the two main mounting notches 18.

[0138] When used in two-pipe or three-pipe air conditioning systems, the installation requirements of two or three shut-off valves 27 can be met by using only the second mounting element 16. Alternatively, the second mounting element 16 can be used to install some of the shut-off valves 27, while the first mounting element 15 can be used to install the other part of the shut-off valves 27, making the layout inside the outdoor unit of the air conditioner more flexible.

[0139] In some embodiments of this application, as shown in FIG4, the first mounting element 15 may have an auxiliary mounting portion 19. The auxiliary mounting portion 19 may be located generally above the first mounting element 15, for example, at the upper edge of the first mounting element 15. Through the auxiliary mounting portion 19, at least one shut-off valve 27 can be mounted in the same direction, for example, in a configuration arranged along the length direction.

[0140] In some embodiments of this application, one refrigerant port of the shut-off valve 27 may be located on one side of the first mounting element 15, and the other refrigerant port may be located on the other side of the first mounting element 15, either in the width direction or the front-rear direction of the housing. For example, the first port 28 of the shut-off valve 27 may be located on the front side of the first mounting element 15, and the second port 29 may be located on the rear side of the first mounting element 15, so that the operating end 30 can be located in a relatively forward position in the housing of the outdoor unit of the air conditioner, extending relative to the first mounting element 15, for ease of operation.

[0141] In some embodiments of this application, the auxiliary mounting portion 19 may include at least one auxiliary mounting notch 20. Each auxiliary mounting notch 20 may be provided with at least one shut-off valve 27. For example, each auxiliary mounting notch 20 may be provided with one shut-off valve 27. The auxiliary mounting notch 20 may be generally U-shaped. The opening of the U-shaped auxiliary mounting notch 20 may be formed at the upper edge of the first mounting element 15. Alternatively, the auxiliary mounting notch 20 may be formed as part of the upper edge of the first mounting element 15.

[0142] In some embodiments of this application, the first mounting element 15 may include an auxiliary mounting notch 20. When applied to a four-pipe air conditioning system, the first mounting element 15 and the second mounting element 16 may be used together. For example, the first mounting element 15 may support and fix one shut-off valve 27, and the second mounting element 16 may support and fix three other shut-off valves 27.

[0143] In some embodiments of this application, the first mounting element 15 and the second mounting element 16 may be detachably fixedly connected to each other.

[0144] In some embodiments of this application, the first mounting element 15 may be approximately trapezoidal. Compared to a rectangular first mounting element, a trapezoidal first mounting element 15 can not only better disperse stress, reduce shear deformation and stress concentration, thereby resisting deformation and maintaining structural stability, but also avoid pipes and other components in the mounting cavity 12 by adjusting the angle and size, thereby enabling the arrangement of more components in a limited space and achieving a more compact and reasonable layout. In addition, this is also more suitable for a layout with fewer mounting gaps at the top and more at the bottom.

[0145] The first mounting element 15 and the second mounting element 16 can be detachably and securely connected to each other via one or more sets of snap-fit ​​assemblies 21, as shown in FIG4. The snap-fit ​​assembly 21 may include a mating snap-fit ​​element 211 and a snap-fit ​​opening 212. One of the snap-fit ​​element 211 and the snap-fit ​​opening 212 may be disposed on the first mounting element 15, and the other may be disposed on the second mounting element 16; the snap-fit ​​element 211 and the snap-fit ​​opening 212 cooperate with each other to secure the first mounting element 15 and the second mounting element 16 together.

[0146] In some embodiments of this application, the first mounting element 15 and the second mounting element 16 can be connected via a first snap-fit ​​assembly and a second snap-fit ​​assembly. The first snap-fit ​​assembly may include a matching first snap-fit ​​element and a first snap-fit ​​opening. The first snap-fit ​​element may be disposed on the main mounting portion 17 of the second mounting element 16, extending forward and protruding from the main mounting portion 17. A first snap-fit ​​interface may be disposed on the first mounting element 15 corresponding to the first snap-fit ​​element. The first snap-fit ​​interface may be a through hole extending in the vertical direction. The first snap-fit ​​element may slide in the first snap-fit ​​interface until it snaps into the first snap-fit ​​interface to achieve a limiting position; for example, the first snap-fit ​​element may slide up and down in the first snap-fit ​​interface until it abuts against the lower edge of the first snap-fit ​​opening to achieve a limiting position.

[0147] Corresponding to the first snap-fit ​​assembly, the second snap-fit ​​assembly may include a matching second snap-fit ​​element and a second snap-fit ​​opening. The second snap-fit ​​element may be disposed on the first mounting element 15, extending rearward from the first mounting element 15 in a protruding form. The second snap-fit ​​interface may be disposed on the main mounting portion 17 of the second mounting element 16, and the second snap-fit ​​interface may be a through hole extending in the vertical direction. The second snap-fit ​​element may slide in the second snap-fit ​​interface until it snaps into the second snap-fit ​​interface to achieve a limiting position; for example, the second snap-fit ​​element may slide in the second snap-fit ​​interface until it abuts against the lower edge of the second snap-fit ​​interface to achieve a limiting position.

[0148] In some embodiments of this application, the first snap-fit ​​component and the second snap-fit ​​component may also be designed as other snap-fit ​​structures.

[0149] In some embodiments of this application, after the first and second snap-fit ​​components are snapped together, the snap-fitted first mounting element 15 and second mounting element 16 can be further secured by fasteners such as bolts. Screw holes for the fasteners to pass through can be located on the main mounting portion 17 of the second mounting element 16 and on the lower portion of the first mounting element 15, for example, at its lower edge.

[0150] In some embodiments of this application, as shown in FIG4, the first mounting element 15 may further include a first body 22. An auxiliary mounting portion 19 of the first mounting element 15 may be connected to the first body 22. The auxiliary mounting portion 19 and the first body 22 may be continuous and integrally formed. In some embodiments of this application, the auxiliary mounting portion 19 and the first body 22 of the first mounting element 15 may not be disposed in the same plane to avoid interference with other components within the housing during installation. For example, the auxiliary mounting portion 19 may have a first bend, and the first body 22 may be connected to one end of the bend, for example, to the end of the first bend away from the auxiliary mounting notch 20. Alternatively, the first body 22 may have a first bend, and the auxiliary mounting portion 19 may be connected to one end of the first bend, for example, to the end of the first bend away from the first body 22. That is, it is sufficient to ensure that the auxiliary mounting portion 19 and the first body 22 are not in the same plane.

[0151] In some embodiments of this application, the second mounting element 16 may further include a second body 23. The second body 23 may be mounted to the base plate 14. The main mounting portion 17 of the second mounting element 16 may be connected to the second body 23. The main mounting portion 17 and the second body 23 may be continuous and integrally formed. In some embodiments of this application, the main mounting portion 17 and the second body 23 of the second mounting element 16 may not be disposed in the same plane to avoid interference with other components within the housing during installation. For example, the second body 23 may have a bent portion, and the end of the second mounting element 16 with the bent portion may be mounted to the base plate 14. In some embodiments of this application, the main mounting portion 17, the second body 23, and any two of the main mounting portion 17 and the second body 23 may be disposed at an angle relative to each other.

[0152] In some embodiments of this application, within the mounting cavity 12 of the outdoor unit's casing, the first mounting element 15 may be positioned relatively close to the casing, and the second mounting element 16 may be positioned relatively far from the casing. A pipe connected to a shut-off valve 27 fixed to the first mounting element 15 can pass between the two shut-off valves 27 fixed to the second mounting element 16, thus preventing interference between the pipe connected to the shut-off valve 27 and the valve body of the shut-off valve 27. In the front-rear direction of the casing, the auxiliary mounting portion 19, the first main body 22, the main mounting portion 17, and the second main body 23 may be arranged sequentially, as shown in FIG5.

[0153] In some embodiments of this application, an operating opening 24 may be provided on the second body 23 of the second mounting element 16, as shown in Figures 5 and 6. The operating opening 24 can penetrate the second mounting element 16. An operator's hand or tools can pass through the operating opening 24 through the second mounting element 16 for installation, maintenance, or debugging. In some embodiments of this application, the operating opening 24 can be a rectangular through hole.

[0154] In some embodiments of this application, a limiting hole 25 may be provided on the first body 22 of the first mounting element 15, as shown in FIG4. The mounting assembly 13 may also include a reinforcing element 33, as shown in FIG5 to FIG7. The limiting hole 25 can be used in conjunction with the reinforcing element 33.

[0155] In some embodiments of this application, the limiting hole 25 can be an elongated narrow hole. For example, the limiting hole 25 can extend along the height direction of the housing. The reinforcing element 33 can be generally strip-shaped. The reinforcing element 33 can be integrally formed continuously and can have a third bend. One end of the reinforcing element 33 can extend into the limiting hole 25 and be snapped into the limiting hole 25, and the other end of the reinforcing element 33 can be detachably (e.g., by bolts) fixed to the housing, or fixed to a frame inside the housing or a frame inside the mounting cavity 12. When multiple shut-off valves 27 are provided simultaneously, the reinforcing element 33 can prevent the first mounting element 15 from shaking, especially during transportation, thereby improving the structural stability of the mounting assembly 13.

[0156] In some embodiments of this application, the second mounting element 16 may be fixedly disposed on the base plate 14. Specifically, a first assembly element may be disposed on the second body 23. A second assembly element may be disposed on the base plate 14. The first assembly element and the second assembly element may cooperate with each other to mount the second mounting element 16 on the base plate 14.

[0157] In some embodiments of this application, the first mounting element may be a connector 26 formed in an opening at the bottom of the second body 23, as shown in FIG8. In one example, the connector 26 may be tongue-shaped. FIG8 is a top view of the second mounting element 16. The connector 26 may extend from front to back, that is, along the width direction. The second mounting element may be a mating member 34 formed on the base plate 14, as shown in FIG9. In one embodiment, the mating member 34 may be a protrusion formed on the base plate 14. The connector 26 may extend into the mating member 34 to mount the second mounting element 16 onto the base plate 14. The mating member 34 may fit tightly with the connector 26. The contact surface between the mating member 34 and the connector 26 may provide sufficient friction to ensure a stable connection of the second mounting element 16. The mating member 34 may also have mutually cooperating guide grooves and / or locking structures to help align and fix the connector 26 during insertion into the mating member 34. The locking structure automatically locks the connector 26 and the mating part 34 after the connector 26 is inserted into the mating part 34, preventing them from disengaging. The locking structure can be any structure known in related technologies, and will not be described in detail here.

[0158] In some embodiments of this application, the refrigerant piping connected to the first interface 28 of the plurality of shut-off valves 27 can pass through the base plate 14 and further connect to the refrigerant piping on the indoor unit side of the air conditioner. To simultaneously match the piping systems of two-pipe, three-pipe, and four-pipe air conditioning systems, a relatively large pipe connection opening 35 needs to be reserved on the base plate 14. In some embodiments of this application, the pipe connection opening 35 may be approximately rectangular, as shown in Figure 9. The length direction of the pipe connection opening 35 may correspond to or be parallel to the length direction along which the plurality of shut-off valves 27 are arranged. In the mounting cavity 12, the pipe connection opening 35 provided on the base plate 14 may be located in front of the second mounting element 16 provided on the base plate 14.

[0159] To allow more refrigerant piping to pass through the pipe connection opening 35 and to provide sufficient assembly space, a certain gap is typically left between the pipe connection opening 35 and the refrigerant piping during installation. Furthermore, to accommodate two-pipe, three-pipe, and four-pipe air conditioning systems, the pipe connection opening 35 is designed to be relatively large. This may allow rodents or other small animals to enter the outdoor unit of the air conditioner through the pipe connection opening 35, posing a risk that they might chew through cables, damage components, or build nests inside the casing, leading to air conditioning system malfunctions. To avoid this risk, in some embodiments of this application, a protective element 36 is also provided on the base plate 14, as shown in Figures 3 and 10 to 12.

[0160] In some embodiments of this application, the protective element 36 may be mounted on one side of the second mounting element 16, such as the front side, on the base plate 14.

[0161] In some embodiments of this application, the protective element 36 may be a generally plate-shaped component. The longitudinal direction of the protective element 36 may correspond to or be parallel to the longitudinal direction along which the plurality of shut-off valves 27 are arranged. The area of ​​the protective element 36 may be larger than the area of ​​the pipe connection opening 35.

[0162] In some embodiments of this application, one or more protective notches may be formed on the protective element 36. The protective notches may extend in the length or width direction. The protective notches may correspond to a refrigerant line and allow the refrigerant line to pass through. One or more independently disposed knockout plates may be provided in the protective notch. The knockout plates may correspond to the refrigerant line. The knockout plates may be disposed in the protective notch. A pre-cut groove may be provided between the knockout plates and the protective notch. At least one knockout plate may be provided in each protective notch. The protective notch may be located below at least one refrigerant line interface (first interface 28 or second interface 29) of the shut-off valve 27 mounted on the first mounting element 15 and / or the second mounting element 16. When the knockout plate is removed, the protective notch where the knocked-out knockout plate is located may expose a previously obscured pipe connection opening. Thus, the protective notch may communicate with the pipe connection opening 35. The protective notch where the knockout plate is knocked out allows the refrigerant line to pass through and extend into the pipe connection opening 35.

[0163] In some embodiments of this application, multiple protective notches and several shut-off valves 27 mounted on the main mounting portion 17 may be arranged in the same direction.

[0164] In some embodiments of this application, a first protective notch 37 and a second protective notch 38 may be formed on the protective element 36, as shown in FIG11. The first protective notch 37 may be configured to allow one refrigerant line to pass through. The second protective notch 38 may be configured to allow multiple refrigerant lines to pass through. The first protective notch 37 and the second protective notch 38 may be arranged sequentially along the length direction of the housing. The first protective notch 37 may extend from back to front in a direction generally parallel to the width direction of the housing, and the second protective notch 38 may also extend from back to front in a direction generally parallel to the width direction of the housing. The extension distance of the second protective notch 38 may be greater than the extension distance of the first protective notch 37, such that the second protective notch 38 may at least partially be located below the first port 28 of the shut-off valve 27 installed on the auxiliary mounting part 19, through which the refrigerant line connected to the first port 28 of the shut-off valve 27 may pass.

[0165] In some embodiments of this application, the protective element 36 may include a first knock-out plate 39 and a second knock-out plate 40, as shown in FIG11. The first knock-out plate 39 and the second knock-out plate 40 may be arranged independently of each other. The first knock-out plate 39 may be disposed in the first protective notch 37, and the second knock-out plate 40 may be disposed in the second protective notch 38. A first pre-cut groove may be provided between the first knock-out plate 39 and the first protective notch 37, and a second pre-cut groove may be provided between the second knock-out plate 40 and the second protective notch 38. Depending on the number of refrigerant pipes required for two-pipe, three-pipe, and four-pipe air conditioning systems, the first knock-out plate 39 and / or the second knock-out plate 40 may be removed when necessary, thereby exposing the previously covered pipe connection opening 35 of the first protective notch 37 and / or the second protective notch 38. Thus, the first protective notch 37 and / or the second protective notch 38 communicate with the pipe connection opening 35. In this way, while completing the refrigerant pipe installation, it can be ensured that there are no large gaps in the remaining area of ​​the air conditioner outdoor unit casing, preventing small animals from entering the casing.

[0166] In some embodiments of this application, the depth of the first pre-cut groove can be 50%-70% of the thickness of the protective element 36.

[0167] In some embodiments of this application, the depth of the second pre-cut groove can be 50%-70% of the thickness of the protective element 36.

[0168] In some embodiments of this application, the first pre-cut groove can penetrate the protective element 36, and the first knock-off plate 39 and the first protective notch 37 can be connected by a plurality of distributed first connection points.

[0169] In some embodiments of this application, the second pre-cut groove can penetrate the protective element 36, and the second knock-off plate 40 and the second protective notch 38 can be connected by a plurality of distributed second connection points.

[0170] In some embodiments of this application, the first pre-cut groove and the second pre-cut groove may partially overlap.

[0171] In some embodiments of this application, a protective notch may be formed on the protective element 36. The protective notch may extend in both the length and width directions. The protective notch may be located below the first interface 28 of the shut-off valve 27 installed in the main mounting portion 17 and the auxiliary mounting portion 19. The protective element 36 may include a third knock-out plate 41, a fourth knock-out plate 42, a fifth knock-out plate 43, and a sixth knock-out plate 44. The third knock-out plate 41, the fourth knock-out plate 42, the fifth knock-out plate 43, and the sixth knock-out plate 44 may be arranged independently of each other. The third knock-out plate 41, the fourth knock-out plate 42, the fifth knock-out plate 43, and the sixth knock-out plate 44 may be disposed in the protective notch. Pre-cut grooves may be provided between the third knock-out plate 41, the fourth knock-out plate 42, the fifth knock-out plate 43, and the sixth knock-out plate 44 and the protective notch, and between the third knock-out plate 41, the fourth knock-out plate 42, the fifth knock-out plate 43, and the sixth knock-out plate 44. Each of the third knockdown plate 41, the fourth knockdown plate 42, the fifth knockdown plate 43, and the sixth knockdown plate 44 can be corresponding to at least one of the refrigerant lines. For example, the dimensions of each of the third knockdown plate 41, the fourth knockdown plate 42, the fifth knockdown plate 43, and the sixth knockdown plate 44 can be designed to correspond to the dimensions of at least one of the refrigerant lines. Depending on the number of refrigerant lines required for two-pipe, three-pipe, and four-pipe air conditioning systems, one or more of the third knockdown plate 41, the fourth knockdown plate 42, the fifth knockdown plate 43, and the sixth knockdown plate 44 can be removed if necessary. This ensures that while the refrigerant lines are installed, there are no large gaps in the remaining area of ​​the outdoor unit's casing, preventing small animals from entering the casing.

[0172] In some embodiments of this application, the depth of the pre-cut groove can be 50%-70% of the thickness of the protective element 36.

[0173] In some embodiments of this application, the pre-cut groove may penetrate the protective element 36. The third knockdown plate 41, the fourth knockdown plate 42, the fifth knockdown plate 43, and the sixth knockdown plate 44 may be connected to the protective notch, and the third knockdown plate 41, the fourth knockdown plate 42, the fifth knockdown plate 43, and the sixth knockdown plate 44 may be connected by a number of distributed connection points.

[0174] In some embodiments of this application, circular openings may also be formed on the third knockdown plate 41, the fourth knockdown plate 42, the fifth knockdown plate 43, and / or the sixth knockdown plate 44. A circular knockdown element 45 is disposed within the circular opening, as shown in FIG3. A pre-cut circular groove may be formed between the circular knockdown element 45 and the circular opening. When the refrigerant line is relatively thin, only the circular knockdown element 45 may be removed to reduce the gap between it and the refrigerant line. The depth of the pre-cut circular groove may be 50%-70% of the thickness of the protective element 36, and the pre-cut circular groove may also penetrate the protective element 36 and be connected to the circular opening through several connection points.

[0175] In some embodiments of this application, concentric circular openings are also formed on the third knockdown plate 41, the fourth knockdown plate 42, the fifth knockdown plate 43, and / or the sixth knockdown plate 44, as shown in FIG3. A circular knockdown element 45 is disposed in the central circular opening. An annular knockdown element 46 is disposed in the circular opening near the periphery. Pre-cut circular grooves can be formed between the circular knockdown element 45 and the circular opening, and between the annular knockdown element 46 and the circular opening. Therefore, depending on the diameter of the refrigerant pipeline, the annular knockdown element 46 and the circular knockdown element 45 can be selected and removed, or only the central circular knockdown element 45 can be removed, so that the refrigerant pipeline can be installed more flexibly. The depth of the pre-cut circular groove can be 50%-70% of the thickness of the protective element 36. The pre-cut circular groove can also penetrate the protective element 36 and can be connected to the circular opening through several connection points.

[0176] In some embodiments of this application, at least one edge of the protective element 36 may extend downward in a direction substantially perpendicular to the plane of the knockout plate, thereby ensuring that the protective element 36 has a certain structural strength after the knockout plate is removed, and will not bend or break.

[0177] In some embodiments of this application, the front edge of the protective element 36 may first extend downward in a direction generally perpendicular to the plane of the knockout plate, and then extend forward in a direction generally parallel to the plane of the base plate 14 to form a joint 47, as shown in FIG11. The joint 47 may be detachably fixed to the base plate 14. In one example, the joint 47 may be, for example, tongue-shaped.

[0178] In some embodiments of this application, one of the two side edges of the protective element 36 may extend downward at an angle to the plane of the knockout plate to form an outwardly extending reinforcing connection 48. For example, the reinforcing connection 48 may extend away from the protective element 36, as shown in FIG12. The reinforcing connection 48 may extend into a through hole in the base plate 14 and interfere with the base plate 14. For example, the reinforcing connection 48 may abut against the wall of the through hole in the base plate 14 to restrict the movement of the protective element 36, thereby further strengthening the fixation of the protective element 36.

[0179] As shown in Figure 1, in some embodiments of this application, the outdoor heat exchanger 10 can be installed on the base plate 14 and close to the side surface of the base plate 14. The outdoor heat exchanger 10 may include a first heat exchange section 50 and a second heat exchange section 49. The first heat exchange section 50 and the second heat exchange section 49 may be arranged symmetrically.

[0180] As shown in Figures 1 and 13, the first heat exchange section 50 may include a continuous first distal portion 51 and a first proximal portion 52. The connection between the first distal portion 51 and the first proximal portion 52 may be located at a first corner C1 of the base plate 14. The end of the first distal portion 51 may extend to form a first distal end portion 53, and the end of the first proximal portion 52 may extend to form a first proximal end portion 54. The connection between the first proximal portion 52 and the first proximal end portion 54 may be located at a second corner C2 of the base plate 14. The first distal end portion 53, the first distal portion 51, the first proximal portion 52, and the first proximal end portion 54 may together form a generally G-shaped region. The height of the first heat exchange section 50 may be approximately the same as the height of the mounting cavity 12 to provide sufficient heat exchange area.

[0181] As shown in Figure 1, the second heat exchange section 49 may include a continuous second distal portion 491 and a second proximal portion 492. The connection between the second distal portion 491 and the second proximal portion 492 may be located at the third corner C3 of the base plate 14. The first distal portion 51 and the second distal portion 491 may be disposed adjacent to each other. The end of the second distal portion 491 may extend to form a second distal end portion 494. The end of the second proximal portion 492 may extend to form a second proximal end portion 493. The connection between the second proximal portion 492 and the second proximal end portion 493 may be located at the fourth corner C4 of the base plate 14. The second distal end portion 494, the second distal portion 491, the second proximal portion 492, and the second proximal end portion 493 may together form another generally G-shaped region. The height of the second heat exchange section 49 may be approximately the same as the height of the mounting cavity 12 to provide sufficient heat exchange area. The first distal end portion 53 and the second distal end portion 494 are disposed adjacent to each other and located at the center of the housing.

[0182] For the installation of the first heat exchange section 50 and the second heat exchange section 49, the outdoor unit of the air conditioner may also include a remote connecting element, a central connecting element 55 and a bottom connecting element 56, as shown in Figure 13.

[0183] In some embodiments of this application, the outdoor heat exchanger 10 may further include a first connecting end plate 81 and a second connecting end plate 82. As shown in Figures 13 and 20, the first connecting end plate 81 may be disposed outside the first distal end 53, and the heat exchange tubes of the first heat exchange section 50 may pass through the first connecting end plate 81. The second connecting end plate 82 may be disposed outside the second distal end 494. The heat exchange tubes of the second heat exchange section 49 may pass through the second connecting end plate 82. A distal connecting element may be disposed between the first connecting end plate 81 and the second connecting end plate 82, and detachably fixedly connected to the first connecting end plate 81 and the second connecting end plate 82.

[0184] As shown in Figures 13 and 20, a central connecting element 55 may be provided on one side (e.g., the front side) of the distal connecting element. The distal connecting element may be detachably fixedly connected to the central connecting element 55. Eaves plates 551 extending away from the central connecting element 55 may be symmetrically provided on both sides of the central connecting element 55. The eaves plates 551 may be detachably fixedly connected to the first connecting end plate 81 and the second connecting end plate 82, respectively, for example, by bolts; thus, the connection can be achieved without affecting the distribution and use of the heat exchange tubes.

[0185] As shown in Figures 13 and 20, the bottom connecting element 56, the center connecting element 55, and the distal connecting element can be sequentially arranged along the direction from the proximal side to the distal side, or along the width or front-back direction of the housing. The bottom connecting element 56 can be located in front of the center connecting element 55 and is detachably fixedly connected to the center connecting element 55. The bottom connecting element 56 may be configured with a bent portion that connects to the base plate 14. The bottom connecting element 56 and the base plate 14 can be detachably fixedly connected by bolts. The bottom connecting element 56 can be located near the proximal end, that is, near the front end of the housing, to facilitate operation by the operator. Note that the term "proximal" as described herein refers to the side of the housing closest to the operator, such as the operating end 30, and the term "distal" refers to the side of the housing furthest from the operator, such as the operating end 30.

[0186] In some embodiments of this application, the distal connecting element may include a first distal connecting element 57 and a second distal connecting element 58. The first distal connecting element 57 and the second distal connecting element 58 may be arranged vertically to provide sufficient structural strength for the connection.

[0187] The first proximal end 54 and the second proximal end 493 are detachably fixed to a bracket inside the housing.

[0188] The outdoor heat exchanger 10 can be installed as a whole. First, the first heat exchange section 50 and the second heat exchange section 49 can be connected using the distal connecting element and the central connecting element 55 to form a double G-shaped structure. Then, the double G-shaped outdoor heat exchanger 10 connected as a whole can be pushed horizontally above the base plate 14 along the direction parallel to the base plate 14, so that the outdoor heat exchanger 10 can be set along the inner peripheral wall of the shell. After being pushed into place, the bottom connecting element 56 can be fixed in front of the central connecting element 55, and the first proximal end 54 and the second proximal end 493 can be fixed to the bracket inside the shell.

[0189] In some embodiments of this application, to provide sufficient support, the base plate 14 may include a first bottom support 59 and a second bottom support 60, as shown in FIG13. The first bottom support 59 and the second bottom support 60 may together form the base plate 14. A connecting cavity 63 may be formed between the first bottom support 59 and the second bottom support 60, as shown in FIG14. A second heat exchange portion 49 may be located above the first bottom support 59. A first heat exchange portion 50 may be located above the second support portion 60. The bottom connecting element 56 may have a symmetrically arranged first bend portion 61 and a second bend portion 62, as shown in FIG14. The first bend portion 61 may be detachably fixedly connected to the first bottom support 59. The second bend portion 62 may be detachably fixedly connected to the second bottom support 60.

[0190] When the piping inside the outdoor unit of an air conditioner is complex, such as in the design of a four-pipe air conditioning system, it may become difficult to install the outdoor heat exchanger as a single unit. To solve this problem, the outdoor unit of the air conditioner may also include a first limiting element 64 and a second limiting element 65, as shown in Figure 14. The first limiting element 64 and the second limiting element 65 may be disposed between the first distal end 53 and the second distal end 494. The first limiting element 64 and the second limiting element 65 are detachably fixedly connected. The first limiting element 64 and the second limiting element 65 may be detachably fixedly connected to the first bottom support 59 or the second bottom support 60, respectively. One of the first limiting element 64 and the second limiting element 65 may be used to guide and position the installation of the first heat exchange section 50, and the other may be used to guide and position the installation of the second heat exchange section 49. The following description will take the example of the first limiting element 64 being used to position the installation of the first heat exchange section 50, and the second limiting element being used to position the installation of the second heat exchange section 49.

[0191] As shown in Figure 19, the first limiting element 64 may include a positioning portion 66. The positioning portion 66 may be disposed close to the first heat exchange portion 50 so that the first heat exchange portion 50 remains vertical during installation. The first limiting element 64 may also include a first connecting portion 67 and a second connecting portion 68. The positioning portion 66, the first connecting portion 67, and the second connecting portion 68 may be continuous and integrally formed. The positioning portion 66 may extend in the width direction as a planar plate. An angle may be formed between the positioning portion 66 and the first connecting portion 67. The first connecting portion 67 may extend downward at an angle relative to the horizontal plane. The second connecting portion 68 may extend vertically downward, and the tail end of the second connecting portion 68 may be bent to form a bend.

[0192] The second limiting element 65 can be disposed close to the second heat exchange section 49, which on the one hand ensures that the second heat exchange section 49 remains vertical during installation, and on the other hand ensures that the first distal end 53 and the second distal end 494 maintain a suitable gap during installation to avoid collision. The second limiting element 65 may include multiple continuously arranged wall portions. The multiple wall portions can form a positioning cavity. The first distal end 53 and the second distal end 494 are respectively located on both sides of the positioning cavity. Specifically, as shown in FIG16, the second limiting element 65 may include a first wall portion 69, a second wall portion 70, and a third wall portion 71. The first wall portion 69, the second wall portion 70, and the third wall portion 71 can be sequentially connected to form a downward-opening positioning cavity 72. The first wall portion 69 and the third wall portion 71 can extend along the width direction of the outer shell. A plurality of positioning holes 73 can be formed on the first wall portion 69 and / or the third wall portion 71. In one embodiment of this application, the positioning holes 73 can be rectangular holes. The second limiting element 65 may also include a connecting bending portion 74. The connecting bend 74 can extend downward from the third wall portion 71. The connecting bend 74 can be detachably fixedly connected to the side of the first bottom support member 59.

[0193] The first limiting element 64 and the second limiting element 65 can be used in conjunction. The first connecting portion 67 of the first limiting element 64 can extend into one of the positioning holes 73 of the second limiting element 65 and be detachably fixedly connected to the first bottom support 59 or the second bottom support 60. The positioning portion 66 can contact a vertically arranged wall portion (e.g., a third wall portion 71). The first connecting portion 67 can extend downwards relative to the horizontal plane until the second connecting portion 68 can extend from a downward opening in the positioning cavity 72. The second connecting portion 68 and its bent end can extend into the connecting cavity 63 and engage with the edge of the first bottom support 59 to form a stable connection. The first limiting element 64 and the second limiting element 65 can be located on the rear side of the central connecting element 55 in the front-rear direction.

[0194] With the assistance of the first limiting element 64 and the second limiting element 65, the first heat exchange unit 50 and the second heat exchange unit 49 can be installed separately.

[0195] First, the first distal connecting element 57 and the second distal connecting element 58 can be detachably and fixedly connected to the first distal end 53, and the center connecting element 55 can be detachably and fixedly connected to the second distal end 494. Then, the first limiting element 64 and the second limiting element 65 can be fixedly mounted on the base plate 14. Then, the first heat exchange part 50 is mounted on one side of the first wall portion 69 of the second limiting element 65, that is, the first wall portion 69 of the second limiting element 65 faces the first heat exchange part 50, and the second limiting element 65 can limit the first heat exchange part 50. The position of the first heat exchanger 50 is determined, and then it is fixed using the bottom connecting element 56 to complete the installation of the first heat exchanger 50. Then, the second heat exchanger 49 can be installed on one side of the first limiting element 64, that is, on the side of the first wall portion 69 of the first limiting element 64 away from the second limiting element 65. The first limiting element 64 can limit the position of the second heat exchanger 49. The first distal connecting element 57 and the second distal connecting element 58 can be connected to the center connecting element 55 to achieve mutual fixation of the first heat exchanger 50 and the second heat exchanger 49.

[0196] According to embodiments of this application, the first heat exchange section 50 and the second heat exchange section 49 may each be G-shaped. According to this application, the installation process of the two separate G-shaped heat exchange sections can be improved, allowing for either integral or separate installation of the outdoor heat exchanger 10, thus increasing flexibility.

[0197] In the description of the above embodiments, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0198] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
