The gap between the middle and bottom beams serves as the condenser's air inlet. This results in a complex, bulky, and heavy overall structure for conventional outdoor units. Summary of the Invention

[0004] Based on this, the present application provides an outdoor unit and an air-conditioning system to improve the problem of large size and heavy weight of the outdoor unit in the prior art.

[0005] To achieve the above objectives, the technical solution of the embodiment of the present application is implemented as follows:

[0034] like Figure 1 As shown, most conventional outdoor units 10 have a frame as their main structure. The frame is composed of at least three sets of crossbeams 14 and several longitudinal beams 15. The three sets of crossbeams 14 are located at the top, middle, and bottom of the frame, respectively. The condenser 12 is located within the frame and secured to the middle crossbeam 142 of the frame. In other words, the frame's accommodating space needs to be slightly larger than the condenser's 12 dimensions to ensure proper installation. A cover plate 16 is provided on each side formed by the upper crossbeam 141, the middle crossbeam 142, and the longitudinal beams 15. A cover plate 16 is also provided around each side of the top fan 11. The control box 13 is provided on one side of the cover plate 16. The condenser 12 draws air through the gap between the middle crossbeam 142 and the lower crossbeam 143. The lower crossbeam 143 is provided with mounting holes for the outdoor unit. This outdoor unit structure, with its mounting holes located on the lower crossbeam 143, can only be installed horizontally (with the fan 11 facing upward), rather than vertically (with the fan 11 and condenser 12 located on either side of the outdoor unit 10). This is not suitable for installation in situations where protection from falling snow, rain, and leaves is required. Furthermore, the conventional outdoor unit 10's cover plate 16 is often made of galvanized sheet metal with a large number of panels, which slows installation and increases the overall weight of the outdoor unit.

[0035] like Figure 2 and Figure 3As shown, the outdoor unit 20 of the embodiment of the present application is used in an air conditioning system and includes a housing, a condenser 22, a fan 21, and footings 27. The housing has an opening at each opposite end, and the condenser 22 and fan 21 are respectively located at the openings at the two ends of the housing. A plurality of footings 27 are respectively located on the outer surface of the condenser 22, and each of the footings 27 is detachably connected to the condenser 22.

[0036] Specifically, in this embodiment, without changing the structure and dimensions of the original condenser 22, fan 21, and other components, the outdoor unit 20 of this embodiment uses the condenser 22 as its base. The upper and lower end plates of the condenser 22 (the top plate of the condenser 22 is the upper end plate, and the bottom plate is the lower end plate in the figure) are heightened and thickened, allowing the chassis assembly to be fixed to the end plates of the condenser 22. This reduces the number of cross-beam structural components and also reduces the overall size of the outdoor unit to a certain extent, including a reduction in thickness (perpendicular to the fan 21 and condenser 22) and a reduction in circumferential cross-sectional area (parallel to the end plates of the condenser 22). The reduction in the number of cross-beam structural components helps reduce the overall weight of the outdoor unit and reduces the manpower and time required to assemble the cross-beam structural components, thereby improving production efficiency.

[0037] like Figure 2 As shown. The chassis of this embodiment includes a frame and cover plates 26 respectively covering the sides of the frame. The cover plates 26 enclose the frame on all sides, and the frame is fixed to the condenser 22. The chassis of this embodiment of the application is generally rectangular in shape, with openings at the upper and lower ends of the chassis. One opening is provided with a fan 21, and the other opening is provided with a condenser 22. The cover plates 26 are arranged on the side of the frame between the fan 21 and the condenser 22. The crossbeams 24 of the frame of this embodiment are provided separately, while the longitudinal beams 25 are integrally formed with two oppositely disposed side panels 262.

[0038] To reduce the number of cover plates 26 used and facilitate assembly of the cover plates 26 and the frame, the cover plates 26 can be bent to form side plates 262 and a top plate 261. The top plate 261 is formed by extending and bending one end of the side plates 262. The side plates 262 enclose the circumferential sides of the frame, while the top plate 261 encloses the gap between the fan 21 and the frame. Because the frame of this embodiment is fixed to the end plates of the condenser 22, compared to the frame of a conventional outdoor unit that surrounds the condenser 22, the circumferential cross-sectional dimensions of the frame of this embodiment are smaller, and the gap between the top surface of the frame and the fan 21 is also smaller. To further reduce the overall weight of the chassis, the cover plates 26 can be made of aluminum alloy plate. Aluminum alloy plate has a lower density, significantly reducing the weight of the structural components. The cover plates 26 can be formed from aluminum alloy plate by spraying.

[0039] The control box 23 of this embodiment is still arranged on one of the cover plates 26. Electrical components are arranged inside the control box 23. The control box 23 is electrically connected to the fan 21, the condenser 22 and the indoor unit of the air conditioner respectively. Since the size of the chassis of the embodiment of the present application is reduced, the size of its side panel 262 is also reduced accordingly. The electrical components inside the control box 23 can be re-layouted so that they can be installed on the cover plate 26.

[0040] Preferably, a foot 27 is provided at each of the four corners of the outer surface of the condenser 22. More foots 27 may be provided depending on actual weight and size requirements. The foot 27 may have mounting holes 274 provided thereon, and connectors may be provided at the mounting holes 274 to secure the outdoor unit 20 to a mounting location such as the ground.

[0041] Specifically, if Figure 4 As shown, in this embodiment, the foot 27 includes a first support plate 271, a second support plate 272, and a third support plate 273. The first support plate 271 and the second support plate 272 are connected to form a right angle. The third support plate 273 is located at the end of the first support plate 271 and the second support plate 272 away from the condenser 22, and the third support plate 273 is arranged perpendicular to the first support plate 271 and the second support plate 272. In other words, the first support plate 271 and the second support plate 272 are connected or integrally formed in the longitudinal direction to form an angle iron structure. The third support plate 273 is connected to the end of the first support plate 271 and the second support plate 272 away from the condenser 22. The three support plates (the first support plate 271, the second support plate 272, and the third support plate 273) are arranged perpendicular to each other. Each support plate has a mounting hole 274, and the number of mounting holes 274 on each support plate is at least two. During installation, the outer surfaces of the first support plate 271 and the second support plate 272 can be flush with the outer surface of the cover plate 26, which can facilitate the vertical installation of the outdoor unit 20 (such as Figure 5 As shown). The first support plate 271 and the second support plate 272 on a foot 27 are flush with the two adjacent cover plates 26, and the first support plate 271 and the second support plate 272 are respectively provided with a mounting hole 274, so that the outdoor unit 20 can be installed with any side plate 262 surface as the bottom surface when it is installed in a vertical position, instead of having only one side plate 262 as the mounting surface, making the installation more convenient. When choosing a vertical installation, only two foot pins 27 are needed, and the other two extra foot pins 27 can be installed freely (such as Figure 5 as shown) or disassembled (as Figure 6 After the third support plate 273 is installed, its surface is parallel to the surface of the condenser 22. The third support plate 273 is provided with a mounting hole 274. The mounting hole 274 can be used for horizontal installation (such as Figure 3 As shown) outdoor unit 20.

[0042] The foot 27 is detachably mounted on the condenser 22. For example, it can be detachably connected to the end plate of the condenser 22 by means of bolts or other connectors. When transporting and handling, the foot 27 is removed from the condenser 22 (e.g. Figure 7 It is more convenient to transport and carry.

[0043] An embodiment of the present application further provides an air-conditioning system, comprising the outdoor unit 20 of the above embodiment, and an indoor unit, wherein the indoor unit is electrically connected to the outdoor unit 20 .

[0044] The outdoor unit and air conditioning system provided in the present embodiment utilizes a condenser assembly as its base. While maintaining the condenser assembly's fin structure, the chassis architecture is redesigned. The upper and lower end plates of the condenser assembly are heightened and thickened, allowing the chassis frame to be fixed to the condenser assembly. This significantly reduces the number of structural components, such as horizontal and longitudinal beams and cover plates, reducing the overall part count and simplifying the assembly process. The chassis cover is replaced with an aluminum alloy plate, effectively reducing the overall weight of the chassis. The detachable feet facilitate installation and allow for a variety of mounting methods. The feet can be removed separately for easier packaging and transport, effectively reducing the thickness of the entire unit and the overall volume of the outdoor unit. This reduces the space required for transportation, increases the number of units that can be stacked, and effectively reduces packaging and transportation costs. The detachable design also makes handling easier. The outdoor unit in the present embodiment can be installed in either a horizontal or vertical position, expanding its applicability. No new components are required; simply connect the connectors to the different mounting holes on the feet, making it easy for users to change the mounting method.

[0045] It should be noted that, in this document, the terms "comprises," "includes," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not exclude the presence of other identical elements in the process, method, article, or apparatus comprising the element.

[0046] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present application should be included in the scope of protection of the present application.
