Description

Technical Field

[0001] This application relates to the technical field of modular air conditioning chassis, and more particularly to a modular air conditioning chassis and an air conditioner. Background Technology

[0002] In air conditioning equipment structures, the chassis is the core component that supports the compressor, condenser, and other parts. It needs to integrate drainage and vibration damping functions, and its performance directly affects the unit's operational stability and operating costs. Currently, the industry mainstream adopts an integral die-casting process to manufacture air conditioning chassis. Although this process can achieve integrated molding of installation interfaces, drainage channels, and other structures, resulting in high efficiency, it is widely used in small and medium-sized units. However, it has two key technical drawbacks: First, poor maintenance economy. When the integral structure causes failure in local functional areas of the chassis, such as corrosion in the drainage area or deformation in the compressor installation area, it cannot be repaired or replaced individually and must be replaced as a whole, significantly increasing maintenance costs and wasting resources.

[0003] Secondly, transportation and installation are inconvenient. For large air conditioning units, the integral die-cast chassis is large in size and heavy in weight, making it difficult to adjust its posture when moving in narrow spaces such as corridors and elevator shafts, and it is easy to be bumped and knocked. Installation requires large equipment, which increases time and labor costs, and may also affect the accuracy of subsequent component assembly due to bumps and knocks. Utility Model Content

[0004] The purpose of this application is to provide a modular air conditioning chassis and an air conditioner to solve the technical problems existing in the prior art.

[0005] To achieve the above objectives, this application adopts the following technical solution: On one hand, a modular air conditioning chassis is provided, comprising: a first plate and a second plate, wherein the first plate has a docking position on one side opposite to the second plate, and the second plate has a docking part capable of docking with the docking position; wherein the structural strength of the second plate is greater than that of the first plate, and an anti-corrosion layer is formed on the surface of the first plate.

[0006] Furthermore, the material of the first disc body is aluminum alloy or galvanized steel sheet.

[0007] Furthermore, the material of the second disc is steel plate or cast iron.

[0008] Furthermore, the volume of the first disc is greater than or equal to that of the second disc, and the weight of the second disc is greater than that of the first disc.

[0009] Furthermore, the first disc body is provided with a flow guide groove and a drain outlet, the drain outlet is connected to the flow guide groove, and the flow guide groove is staggered on the upper surface of the first disc body.

[0010] Furthermore, the guide channel has at least a first end and a second end, the first end being connected to the drain outlet, the second end being away from the drain outlet, and there is a height difference between the first end and the second end, so that the guide channel as a whole is inclined toward the drain outlet.

[0011] Furthermore, the bottom of the second disc is provided with multiple shock-absorbing pads.

[0012] Furthermore, the first disc body and the second disc body are locked and fixed by fasteners; or the first disc body and the second disc body are locked and fixed by a snap-fit ​​structure.

[0013] Furthermore, it also includes at least three support members, two of which are respectively installed at the bottom of the first disc and the bottom of the second disc, and the other support member is installed below the docking position of the first disc and the second disc.

[0014] On the other hand, an air conditioner is also provided, including the modular air conditioner chassis as described above.

[0015] The beneficial effects of this application are as follows: through the modular splicing and functional adaptation of the first and second discs, the high structural strength of the second disc is adapted to the compressor area, and the anti-corrosion layer of the first disc is adapted to the drainage area, which can accurately correspond to the functional areas of the chassis. This means that when a partial failure occurs, there is no need to replace the whole disc, but only to replace the failed disc, which greatly reduces maintenance costs and reduces resource waste. Moreover, after disassembly, the size and weight of the individual discs are significantly reduced, making it more flexible to move in narrow spaces. Installation does not require large equipment, and the accuracy can be ensured through standardized docking, avoiding affecting the assembly of core components and the stability of unit operation.

[0019] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] In the description of this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0021] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0022] like Figures 1-4 As shown, this embodiment provides a modular air conditioning chassis, including: a first chassis 1 and a second chassis 2. The first chassis 1 has a docking position 101 on one side opposite to the second chassis 2, and the second chassis 2 has a docking part 201 that can dock with the docking position 101. The structural strength of the second chassis 2 is greater than that of the first chassis 1, and the surface of the first chassis 1 is formed with an anti-corrosion layer.

[0023] Based on the above solution, this application adopts a modular splicing design of the first disc 1 and the second disc 2, combined with functional adaptability optimization. Specifically, the high structural strength of the second disc 2 matches the load-bearing requirements of the compressor installation area, and the anti-corrosion layer on the surface of the first disc 1 matches the rust resistance requirements of the drainage area, achieving a precise correspondence between the functional areas and components of the chassis. When a partial failure occurs in a certain functional area, such as the drainage area failing due to rust or the compressor installation area failing due to deformation, it is not necessary to disassemble and replace the entire chassis as required by existing integral die-cast chassis. Only the failed first disc 1 or second disc 2 needs to be disassembled and replaced separately. This significantly reduces maintenance costs and avoids the idle waste of intact functional areas of the chassis, which is in line with the technological trend of green manufacturing and efficient resource utilization.

[0024] Compared to existing large integral die-cast chassis, this application splits the chassis into independent first plate 1 and second plate 2, significantly reducing the size and weight of individual components. When transporting in confined spaces such as corridors and elevator shafts, the posture can be adjusted by handling the components separately, effectively avoiding the risk of collisions caused by the large size of the integral chassis. During the installation phase, there is no need to rely on large hoisting equipment. Precise splicing can be achieved only through the docking position 101 of the first plate 1 and the docking part 201 of the second plate 2. This not only reduces labor and equipment costs, but also ensures the accuracy of the installation reference surface of the chassis after splicing through a standardized docking structure. It avoids the impact of transportation collisions on the coaxiality of subsequent assembly of core components such as compressors and condensers, further improving the operational stability of the air conditioning unit.

[0025] In addition, the differentiated design of the first panel 1 and the second panel 2 allows for flexible adjustment of the material and size parameters of each panel according to the specific load requirements and environmental conditions of the air conditioning unit. This not only meets the lightweight requirements of small and medium-sized units, but also adapts to the load-bearing requirements of large units by optimizing the docking structure. This solves the limitations of the existing integral die-cast chassis in the application of different specifications of units and improves the applicability of the technical solution.

[0026] The anti-corrosion layer is made of epoxy resin, polyurethane, or polytetrafluoroethylene (PTFE). Epoxy resin coating uses epoxy resin as the film-forming base material, combined with amine curing agents to form a cross-linked structure. The coating adheres tightly to the surface of the metal substrate, isolating water, oxygen, and corrosive ions from contact with the substrate, while also exhibiting excellent chemical stability. Polyurethane coating forms a polyurethane resin film through the reaction of isocyanate and polyol. Its molecular structure contains strongly polar urethane bonds, providing both excellent water resistance and resistance to UV aging. PTFE coating uses PTFE as the main component, forming a dense coating through high-temperature sintering. Its molecular structure has extremely high CF bond energies, resisting strong acids, strong alkalis, and most organic solvents, and its low surface tension prevents condensation residue.

[0027] Specifically, the first tray 1 is made of aluminum alloy or galvanized steel sheet, and the second tray 2 is made of steel sheet or cast iron. Aluminum alloy has low density, which can significantly reduce the unit volume weight of the first tray 1, meeting the lightweight requirements for transportation and installation; at the same time, a dense aluminum oxide film can be formed on the surface of the aluminum alloy through anodizing process. This film layer is integrated with the substrate, which can isolate the condensate and moisture in the drainage area from contact with the substrate, and the film layer has high hardness, which can resist minor scratches during handling and avoid damage to the anti-corrosion layer.

[0028] In galvanized steel sheets, zinc has a lower electrode potential than iron. When moisture in the drainage area causes micro-corrosion of the substrate, the zinc layer preferentially undergoes an oxidation reaction, thereby protecting the steel substrate from rust. At the same time, the tensile strength of the steel substrate can meet the structural strength requirements of the first plate 1, avoiding local deformation caused by the weight of accumulated water in the drainage area.

[0029] The steel plate has high tensile strength and good toughness, and can withstand the periodic vibration load and starting impact load during the operation of the compressor. Its rigidity can ensure the flatness of the compressor mounting reference surface, avoid the coaxiality deviation between the compressor and the pipeline caused by the deformation of the plate, and thus prevent operating noise and component wear.

[0030] Ductile iron, through spheroidizing treatment, distributes graphite in a spherical shape, possessing both high compressive strength and good rigidity, capable of withstanding the long-term effects of the compressor's static weight and dynamic loads; its high material hardness can resist local extrusion deformation caused by bolt preload during compressor installation, ensuring the long-term dimensional stability of the mounting holes.

[0031] Specifically, the volume of the first plate 1 is greater than or equal to that of the second plate 2, and the weight of the second plate 2 is greater than that of the first plate 1. The first plate 1 needs to integrate the drainage area and the installation area for non-heavy-load components such as the fan and condenser. This function requires a larger planar space to achieve efficient condensate drainage and multi-component layout, so its volume is set to be greater than or equal to that of the second plate 2. The core function of the second plate 2 is to support the compressor, and it only needs a local rigid support space that matches the size of the compressor base. There is no need for redundant volume. The small volume design can avoid material waste and optimize the overall layout of the chassis.

[0032] Based on the material settings of the first disc 1 and the second disc 2, the second disc 2 achieves a greater weight than the first disc 1 by using higher density materials or a larger amount of material per unit volume. Behind the weight difference is a quantitative reflection of load-bearing performance; the higher weight corresponds to higher structural strength and rigidity, which can meet the vibration load and static weight bearing requirements during compressor operation. While the first disc 1 is larger in volume, it relies on low-density materials to control its weight, avoiding excessive weight of the overall chassis due to its large volume.

[0033] In some embodiments, the first disc 1 is provided with a flow guide 102 and a drain outlet 103, the drain outlet 103 being connected to the flow guide 102, and the flow guide 102 being staggered on the upper surface of the first disc 1. The staggered flow guide 102 forms a mesh-like fluid guiding path on the upper surface of the first disc 1 through a preset slope (typically designed as a small inclination angle of 0-3°), which can cover the entire area of ​​the disc. When condensate or ambient water generated during air conditioner operation drips onto the surface of the panel, it is quickly collected by the guide channels 102 in different directions, preventing static water accumulation in local areas. The guide channels 102 are connected by nodes to form a converging channel, which eventually converges to the preset drain outlet 103. The drain outlet 103 is usually located at the lowest potential energy point of the guide channel network 102, and the condensate is discharged in a concentrated manner by means of gravity. At the same time, the drain outlet 103 can be connected to the main drainage system of the outdoor unit of the air conditioner through pipelines to form a complete water flow path. In addition, the staggered layout of the guide channels 102 avoids the docking position 101 between the first panel 1 and the second panel 2, which ensures the drainage function while avoiding interference between the guide channels 102 and the splicing structure, ensuring the accuracy and stability of modular assembly.

[0034] Specifically, the guide channel 102 has at least a first end and a second end. The first end is connected to the drain outlet 103, and the second end is away from the drain outlet 103. There is a height difference between the first end and the second end, so that the guide channel 102 is tilted towards the drain outlet 103. The tilted structure drives the condensate to quickly converge towards the drain outlet 103 by gravity. Even in low water volume scenarios, it can prevent water film from stagnating in the channel, greatly reducing the risk of microbial growth and long-term immersion corrosion at the bottom of the guide channel 102 caused by water accumulation. It is especially suitable for the long-term anti-corrosion requirements of the drainage area of ​​the first plate 1. At the same time, the preset height difference can compensate for the slight level deviation of the air conditioner chassis during on-site installation. It can ensure normal drainage function without strict calibration of the chassis level, reducing installation and debugging time and labor costs, and avoiding backflow problems at the drain outlet 103 caused by installation deviation.

[0035] Generally, the bottom of the second disc body 2 is equipped with multiple vibration damping pads. As the core component of the air conditioner chassis that carries the compressor, the multiple vibration damping pads at the bottom of the second disc body 2 essentially achieve vibration control through elastic deformation energy dissipation and vibration transmission path optimization: During the operation of the compressor, periodic vibrations are generated, which are transmitted to the body of the second disc body 2 through the installation interface between the compressor and the second disc body 2. At this time, the multiple vibration damping pads can absorb the vibration energy through their own elastic deformation, converting the mechanical energy of the vibration into a small amount of heat energy for dissipation. At the same time, the low stiffness characteristics of the elastic material are used to change the vibration transmission frequency, avoiding resonance between the second disc body 2 and other components of the air conditioner. In addition, the distributed arrangement of multiple vibration damping pads can transform the concentrated load transmitted by the compressor into a dispersed elastic support force, avoiding the elastic failure of a single vibration damping pad due to excessive local load, and ensuring the stability of the vibration attenuation effect.

[0036] Among them, the shock-absorbing pads can be made of elastic materials such as nitrile rubber and EPDM rubber, which have excellent damping characteristics and aging resistance.

[0037] Optionally, the first disc 1 and the second disc 2 are locked together by fasteners. This solution achieves disc fixation and protection through a combination of rigid mechanical connection and flexible sealing. M6 / M8 stainless steel bolts serve as the core connecting components, evenly distributed along the mating edges of the first disc 1 and the second disc 2. After the bolts pass through the pre-made mounting holes of the two discs, they are tightened with nuts. The high strength of stainless steel is used to construct a stable load transmission path, ensuring that the vibration load of the second disc 2 and the static load of the first disc 1 can be transmitted evenly. At the same time, EPDM (ethylene propylene diene monomer) waterproof strips are pre-installed between the mating surfaces of the two discs. The compression of the strips is controlled at 30%-50%, and its elastic deformation can fill the micro-gaps on the mating surfaces, forming a continuous sealing interface and preventing condensate and ambient moisture from seeping into the chassis or metal connection parts from the mating gaps.

[0038] As an optional specific implementation, the first disc body 1 and the second disc body 2 are locked together by a snap-fit ​​structure. This solution focuses on elastic locking and precise positioning, adapting to the convenient assembly and disassembly requirements of light-duty units. A snap-fit ​​assembly with a spring is provided at the docking position 101 of the first disc body 1, and a snap-fit ​​groove and positioning hole are provided at the corresponding position of the second disc body 2. During assembly, the positioning pin is first inserted into the positioning hole of the two disc bodies to achieve precise alignment of the docking position 101, and then the second disc body 2 is pushed to make the snap-fit ​​engage with the groove. The preload of the spring makes the snap-fit ​​and the groove form an interference fit, completing the quick locking of the two disc bodies. During disassembly, the two disc bodies can be separated by pressing the snap-fit ​​unlocking component to compress the spring, without the need for tools.

[0039] It is worth mentioning that at least three support members 3 are also included. Two of the support members 3 are respectively installed at the bottom of the first disc 1 and the bottom of the second disc 2, and the third support member 3 is installed below the docking position 101 of the first disc 1 and the second disc 2. Horizontally, the two support members 3 correspond to the bottom of the first disc 1 and the second disc 2, respectively, and are both within the horizontal span of their respective discs. For example, the bottom support member 3 of the first disc 1 is close to the side away from the docking end, and the bottom support member 3 of the second disc 2 is close to the side away from the docking end. The third support member 3 is precisely set directly below the docking position 101 of the first disc 1 and the second disc 2, forming a horizontally spaced support layout with two ends and a middle section, ensuring that the load-bearing area of ​​the chassis has a direct support point.

[0040] When the chassis bears the vertical load of the upper components, the three horizontally spaced support members 3 can evenly distribute the load in the horizontal direction. The load of the first disc 1 is transferred to the mounting surface through its bottom support member 3, and the load of the second disc 2 is transferred through its bottom support member 3. However, the load concentration that may occur at the joint 101 due to the splicing of the two discs is directly offset by the support member 3 below the joint, thus avoiding the load being transferred only from the structure of the two discs themselves to the support members 3 at both ends, which could cause deformation or cracking of the splicing interface due to excessive stress.

[0041] The horizontally spaced distribution ensures that the support force is applied evenly along the horizontal axis of the chassis, preventing the chassis from tilting due to the support points deviating from the horizontal direction. Especially in scenarios where the volume of the first plate 1 is greater than or equal to that of the second plate 2, the horizontally distributed support can balance the weight difference between the two plates, preventing the first plate 1 from sagging at both ends due to its larger weight, and ensuring the accuracy of the mounting reference surface on the upper surface of the chassis.
