While exemplary embodiments of this application are shown in the drawings, it should be understood that this application may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of this application and to fully convey the scope of this application to those skilled in the art.

[0035] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also include the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not construed as requiring them to be performed in a particular order described or illustrated unless the order of performance is explicitly indicated. It should also be understood that additional or alternative steps may be used.

[0036] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Therefore, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.

[0037] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "over," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure is flipped, an element described as "below other elements or features" or "below other elements or features" would subsequently be oriented as "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0038] This application provides an HVAC system that can be used as a cooling or heating device, such as a household air conditioner, central air conditioner, heat pump system, or multi-split system. The HVAC system includes an outdoor unit and an indoor unit connected to the outdoor unit via piping. The indoor unit is typically installed indoors, while the outdoor unit is typically installed outdoors. The indoor and outdoor units work together to achieve cooling, heating, dehumidification, and air purification functions, thereby achieving comfortable air quality.

[0039] When HVAC equipment is used as a central air conditioning system, there is usually one outdoor unit, while there can be multiple indoor units. Each indoor unit has one or more exhaust vents to discharge cooled, heated, dehumidified, or purified air into the room. The indoor units typically contain an indoor heat exchanger, and the outdoor units typically contain an outdoor heat exchanger. The indoor and outdoor heat exchangers are usually connected by refrigerant pipes, allowing refrigerant to circulate between them. In the cooling process of HVAC equipment, the indoor heat exchanger acts as an evaporator. The refrigerant in the evaporator changes from a liquid to a gaseous state, absorbing heat during evaporation. During this process, the evaporator exchanges heat with the air flowing through it, carrying away heat from the air inside the indoor unit. This results in the air being discharged from the indoor unit after releasing heat and cooling, causing the indoor unit to blow out cold air. Simultaneously, the outdoor heat exchanger acts as a condenser. The refrigerant in the condenser changes from a gaseous state to a liquid state, releasing heat during condensation. During this process, the condenser exchanges heat with the air flowing through it, carrying the heat from the condenser to the outside of the outdoor unit, thus achieving the cooling process. In the heating process of HVAC equipment, the outdoor heat exchanger acts as an evaporator. The refrigerant in the evaporator changes from a liquid state to a gaseous state, absorbing heat during evaporation. During this process, the evaporator exchanges heat with the air flowing through it, transferring the heat carried by the air in the outdoor unit to the refrigerant. Simultaneously, the indoor heat exchanger acts as a condenser. The refrigerant in the condenser changes from a gaseous state to a liquid state, releasing heat during condensation. During this process, the condenser exchanges heat with the air flowing through it, allowing the air in the indoor unit to carry away the heat carried by the condenser and discharge it from the indoor unit to the outside of the room, thus blowing hot air from the indoor unit. This achieves the heating process.

[0040] According to some embodiments of this application, the outdoor unit assembly for HVAC equipment proposed in this application further includes a housing and a panel assembly. The housing is provided with an air outlet, the panel assembly is disposed at the air outlet, and has a ventilation opening corresponding to and connected to the air outlet.

[0041] The shell contains components such as an outdoor heat exchanger, compressor, and refrigerant piping.

[0042] For example, an air outlet is provided on the side of the housing, and a panel assembly is mounted on the side of the housing.

[0043] See Figures 1 to 3 , Figure 1 This is an exploded structural diagram of the first plate and the protective member according to an embodiment of this application; Figure 2 for Figure 1 Enlarged structural diagram of section A in the middle; Figure 3This is a schematic diagram of the assembly structure of a first plate and a protective member according to an embodiment of this application. According to some embodiments of this application, a panel assembly 10 includes a first plate 11 and a protective member 12. The first plate 11 has a connecting hole 111 extending through the thickness direction of the first plate 11 and used for fasteners to pass through and fix the first plate 11. The first plate 11 has a first edge and a second edge arranged opposite to each other. The connecting hole 111 is located near the first edge and has a first gap 114 and a second gap between it and the first edge and the second edge, respectively. The first gap 114 is smaller than the second gap. The protective member 12 is disposed on one side of the first plate 11 in the thickness direction and surrounds the periphery of the connecting hole 111, and the protective member 12 at least covers a portion of the first gap 114.

[0044] In this embodiment, for example, the connecting hole 111 is a threaded hole, and the minimum size of the first gap 114 is set in the range of 4mm-5mm. The minimum size of the first gap 114 is the minimum distance between the edge of the threaded hole and the first edge of the first plate 11.

[0045] For example, the protective component 12 can be a protective plate or a protective pad, and the thickness of the protective component 12 is set in the range of 2mm-4mm. The protective component 12 can be made of plastic or metal.

[0046] For example, fasteners can be bolts or screws, etc.

[0047] According to the panel assembly 10 proposed in the embodiments of this application, the first plate 11 of the panel assembly 10 is provided with a connection hole 111. The connection hole 111 is located near the first edge of the first plate 11 and has a first gap 114 between it and the first edge of the first plate 11. By providing a protective member 12 on one side of the panel assembly 10 in the thickness direction corresponding to the position of the connection hole 111, the protective member 12 surrounds the peripheral edge of the connection hole 111 and at least covers part of the first gap 114. When the panel assembly 10 is assembled and connected using fasteners, during the process of the fasteners passing through the protective member 12 and the connection hole 111 of the first panel assembly 10 and connecting, the force generated by the connection can be applied to the protective member 12 first. Since the protective member 12 has a certain thickness and at least covers part of the first gap 114, the connection strength at the position of the first gap 114 of the first plate 11 can be increased, thereby reducing the risk of cracking in the area where the first gap 114 is located and improving the service life of the panel assembly 10.

[0048] In some embodiments, the protective members 12 are provided on both sides of the first plate 11 in the thickness direction, and the two protective members 12 are arranged around the periphery of the connecting hole 111 and at least cover part of the first gap 114.

[0049] According to some embodiments of this application, the protective member 12 has a first surface and a second surface disposed opposite to each other. The first surface is attached to the first plate 11 and covers at least part of the first gap 114. Along the direction from the protective member 12 to the first plate 11, the projection of the second surface on the first surface is located within the first surface.

[0050] That is, the surface area of ​​the first surface is not less than the surface area of ​​the second surface, and the projection of the first surface on the first plate 11 covers the projection of the second surface on the first plate 11. In this way, since the second surface of the protective member 12 covers at least part of the first gap 114 and has a relatively large contact area with the first plate 11, the risk of cracking in the area of ​​the first gap 114 due to stress concentration during fastener connection can be reduced.

[0051] Please see Figure 2 According to some embodiments of this application, the second surface of the protective member 12 is provided with a groove 124, which extends from the connecting hole 111 to the first edge of the first plate 11 and covers part of the first gap 114.

[0052] For example, the depth of the groove 124 can be set in the range of 0.8mm-1.2mm.

[0053] By providing a groove 124 on the second surface of the protective member 12, and the groove 124 covering part of the first gap 114, when the fastener passes through the protective member 12 and the connecting hole 111, the fastener does not contact the bottom wall of the groove 124, thereby reducing the squeezing force on the groove 124 area when the fastener is fastened, and further reducing the risk of cracking in the first gap 114 area.

[0054] Please see Figure 2 According to some embodiments of this application, the protective member 12 is defined with a through hole 123, which is connected to the connecting hole 111.

[0055] For example, both the connecting hole 111 and the through hole 123 are circular holes.

[0056] The protective component 12 has a through hole 123 that corresponds to and communicates with the connecting hole 111. When the fastener is assembled with the panel assembly 10, it can pass through the through hole 123 and the connecting hole 111 respectively to lock the panel assembly 10 to the external structure, thereby reducing the risk of damage caused by force concentration. The structure and principle are relatively simple and easy to implement.

[0057] According to some embodiments of this application, the protective component is integrally formed with the first plate.

[0058] The protective component 12 is integrally formed on the first plate 11, eliminating the need for separate assembly and connection. This not only helps improve the stability of the protective function of the protective component 12, but also helps simplify the product assembly process and improve the product production efficiency.

[0059] According to some embodiments of this application, the protective element 12 is annular.

[0060] By setting the protective component 12 in a ring shape, the ring structure is relatively regular, which is easy to process and form, suitable for mass production, and helps to improve the production efficiency of the product.

[0061] Please see Figure 2 According to some embodiments of this application, the protective member 12 includes an arcuate portion and an extension portion connected to the arcuate portion. The extension portion is located between the arcuate portion and the first edge of the first plate and covers the first gap 114. The orthographic projection of the arcuate portion on the first plate is a semi-circular ring along the direction from the protective member 12 to the first plate 11.

[0062] The arc-shaped portion 121 is semi-circular and surrounds the side of the connecting hole 111 away from the extension portion 122. The extension portion 122 is connected to the two end faces of the arc-shaped portion 121 and extends to the first edge of the first plate 11 to cover the first gap 114 between the first edge of the first plate 11 and the connecting hole 111. This can further increase the contact area between the protective member 12 and the first plate 11, thereby further reducing the risk of cracking in the area of ​​the first gap 114 when the fastener connects the first plate 11.

[0063] According to some embodiments of this application, the panel assembly 10 further includes fasteners, which include bolts and washers. The washers are mounted on the side of the protective member 12 away from the first plate 11. The bolts are used to pass through the washers, the protective member, and the connecting holes to fix the first plate 11. The orthographic projection of the washers on the first plate 11 is located within the first plate 11 along the direction from the protective member 12 to the first plate 11.

[0064] The gasket is installed on the side of the protective member 12 away from the first plate 11, and along the direction from the protective member 12 to the first plate 11, the orthogonal projection of the gasket on the first plate 11 is located inside the plate, so that the protective member 12 can play a stable supporting role for the gasket, thereby reducing the risk of bending and damage to the gasket during bolt connection and helping to improve the reliability of the connection.

[0065] According to some embodiments of this application, the first plate 11 is a plastic plate.

[0066] Plastic sheets are easy to process and mold, have low cost, and are lightweight, which helps to reduce product production costs and improve product assembly convenience.

[0067] Please see Figure 4and Figure 5 , Figure 4 This is a schematic diagram of the structure of a panel assembly provided according to an embodiment of this application from one perspective; Figure 5 This is a structural schematic diagram of a panel assembly provided according to an embodiment of the present application from another perspective. According to some embodiments of the present application, the panel assembly 10 further includes a second plate 13, which is disposed intersecting with the first plate 11 and located on the side of the second plate 13. The second plate 13 is provided with a ventilation opening, and at least one side of the second plate 13 in the thickness direction is provided with a grille 14.

[0068] For example, the area of ​​the second plate 13 is larger than that of the first plate 11. The first plate 11 is configured to be disposed on the side of the second plate 13.

[0069] The first plate 11 serves as a side plate of the second plate 13 and is connected to the housing of the outdoor unit of the HVAC system via fasteners. By providing vents on the second plate 13, when the panel assembly 10 is located at the air outlet of the housing, the vents can communicate with the air outlet, facilitating the flow of gas inside and outside the housing through the vents and the air outlet. Furthermore, by providing a grille 14 on at least one side of the second plate 13 in the thickness direction, the grille 14 defines a ventilation gap for gas flow. This ventilation gap not only allows for gas flow but also, due to its small size, reduces the risk of foreign objects entering the housing, thus contributing to improved stability and safety of the outdoor unit's operation.

[0070] In some embodiments of this application, the panel assembly 10 further includes a plurality of side panels, which are disposed around the periphery of the second panel 13 along with the first panel 11.

[0071] In some embodiments of this application, a plurality of support members 15 are provided between the first plate 11 and the second plate 13. The plurality of support members 15 are spaced apart along the extension direction of the first plate 11 and are used to support the first plate 11.

[0072] In some embodiments of this application, the second plate 13 is provided with a plurality of mounting holes, which are respectively used for passing through a plurality of connectors to fix the second plate 13 to the housing of the outdoor unit of the HVAC equipment.

[0073] The above description is merely a preferred embodiment 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 technical scope 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.
