Description

Technical Field

[0001] The utility model belongs to the technical field of air conditioner plates, and particularly relates to a metal plate for an air conditioner with high strength. Background Art

[0002] The air conditioner metal plate is a key component inside the air conditioner, usually made of high-quality metal materials such as aluminum alloy or stainless steel. Its core function is to provide a solid structural support and comprehensive protection for the core components of the air conditioner. These metal plates are carefully designed and precisely manufactured, with good strength and excellent stability, and can fully withstand the vibration and pressure generated during the operation of the air conditioner;

[0003] For example, in the outer shell part of the air conditioner, the metal plate not only plays a role in beautifying the appearance, but also can effectively block external impurities such as dust and water vapor from entering the air conditioner, thereby strongly protecting the internal precision parts. In the internal air duct system of the air conditioner, the metal plate can effectively guide the flow of air, strongly ensuring the uniform distribution of the cooling or heating effect;

[0004] The Chinese patent with the publication number "CN116001383A" discloses a color-coated steel plate for an air conditioner outdoor unit casing and its preparation method, which includes a steel plate seat. A steel plate main body is integrally formed in the middle of the steel plate seat. The steel plate main body includes a topcoat, a primer, an upper chemical treatment layer, a base material, a lower chemical treatment layer, and a back paint. Among them, the upper chemical treatment layer is on the upper surface of the base material, the primer is on the upper surface of the upper chemical treatment layer, the topcoat is on the upper surface of the primer, the lower chemical treatment layer is on the lower surface of the base material, and the back paint is on the lower surface of the lower chemical treatment layer. And, an upper steel plate is covered at the position on the upper surface of the steel plate main body on the steel plate seat.

[0005] During the actual use of the above device, although it can assist the air conditioner to show better performance to a certain extent, there is still a problem of lack of high-strength support and reinforcement performance during its application. You know, the use strength of the air conditioner is extremely important. For example, for an air conditioner outdoor unit installed outdoors, if its overall stability is poor and its strength is low, then the air conditioner is very likely to accidentally fall, resulting in a dangerous situation of the air conditioner outdoor unit falling from a height. Thus, there are certain defects and deficiencies in its overall application, and it is urgently necessary to improve and perfect it. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] Embodiment

[0025] Refer to Figures 1 to 4 , a metal plate for a high - strength air conditioner in this embodiment includes a main composite steel plate 1. The main composite steel plate 1 is composed of a composite steel layer 2. An inner support frame 3 is fixedly connected to the inner side of the main composite steel plate 1, and secondary support steel parts 4 are fixedly installed on both sides of the main composite steel plate 1;

[0026] The composite steel layer 2 includes a base layer 21 which is arranged on the innermost side of the main composite steel plate 1. A heat-conducting and heat-dissipating layer 22 is fixedly installed on the outer side of the base layer 21. The outer side of the heat-conducting and heat-dissipating layer 22 is fixedly connected to a support layer 23, and the outer side of the support layer 23 is fixedly connected to an outer layer 24. The main composite steel plate 1 is composed of the composite steel layer 2. The inner support frame 3 on the inner side enhances the stability of the internal structure, can effectively disperse the stress generated during the operation of the air conditioner, and reduces the risk of deformation. The auxiliary support steel parts 4 on both sides further strengthen the overall strength. The base layer 21 in the composite steel layer 2 is located on the innermost side to provide basic support. The heat-conducting and heat-dissipating layer 22 is conducive to quickly conducting and dissipating heat, improving the working efficiency of the air conditioner. The support layer 23 enhances the support performance of the plate to ensure that it does not deform under various working conditions. The outer layer 24 plays a role in protecting and enhancing the overall strength. This structural design enables the metal plate to have high strength, good heat-conducting and heat-dissipating performance, and a stable structure, can adapt to the complex working environment of the air conditioner, and ensure its long-term stable operation.

[0027] Reference Figure 4 , the base layer 21 is set as a stainless-steel base layer 21, the heat-conducting and heat-dissipating layer 22 is set as an aluminum-alloy heat-conducting layer, the support layer 23 is set as a titanium-alloy layer, and the outer layer 24 is set as a transformation-induced plasticity steel layer. The stainless-steel base layer 21 endows good corrosion resistance and stability, can resist external erosion for a long time, and is not easy to rust and damage. The aluminum-alloy heat-conducting layer has excellent heat-conducting and heat-dissipating performance, can quickly conduct and dissipate the heat generated during the operation of the air conditioner, improve the air-conditioning efficiency and reduce energy consumption. The titanium-alloy support layer 23 provides strong and stable support for the plate with its high strength and low density characteristics, ensures that it does not deform under complex working conditions, and enhances the overall structural strength. The transformation-induced plasticity steel outer layer 24 has both good strength and toughness, can effectively absorb the energy brought by external impacts, collisions and pressures, reduce the risk of deformation and damage, and has good forming performance, which is convenient for manufacturing various shapes. This composite structure makes the plate have excellent performance and can meet the requirements of the air conditioner in various environments and working conditions.

[0028] Reference Figure 3 , the inner support frame 3 is composed of transverse support bars 31 and longitudinal support bars 32 arranged in an alternating manner. Both the transverse support bars 31 and the longitudinal support bars 32 are set as tungsten-alloy support bars. The structure composed of the transverse support bars 31 and the longitudinal support bars 32 arranged in an alternating manner can form a stable support network. By setting them as tungsten-alloy support bars, since tungsten alloy has high strength, high hardness, good wear resistance and corrosion resistance, it enhances the overall strength and durability of the inner support frame 3, enabling it to more effectively withstand and disperse the pressure and stress from all directions, thereby providing more reliable internal support for the entire metal plate of the air conditioner and ensuring the stability and safety of the metal plate of the air conditioner during long-term use.

[0029] Reference Figure 1 and Figure 3, the secondary support steel member 4 includes an outer support plate 41 which is fixedly connected to both sides of the main composite steel plate 1. Longitudinal outer support bars 42 and transverse outer support bars 43 are fixedly connected to the outer side of the outer support plate 41 at equal intervals. The longitudinal outer support bars 42 and the transverse outer support bars 43 are alternately arranged and fixed to the outer side of the outer support plate 41. The outer support plate 41 is set as a tungsten steel alloy support plate, and the longitudinal outer support bars 42 and the transverse outer support bars 43 are both set as tungsten steel alloy outer support bars. This design of the secondary support steel member 4 has multiple advantages. The outer support plate 41 is fixed to both sides of the main composite steel plate 1, providing double-sided strengthening support for it. The longitudinal outer support bars 42 and the transverse outer support bars 43 that are alternately arranged at equal intervals on the outer side of the outer support plate 41 form a stable support structure. Setting both the outer support plate 41 and the longitudinal outer support bars 42 and the transverse outer support bars 43 as tungsten steel alloy materials endows the secondary support steel member 4 with excellent performance due to the high strength, high hardness, good wear resistance and corrosion resistance of tungsten steel alloy. It can greatly enhance the overall strength and stability, effectively disperse external forces, reduce the risk of deformation and damage, and thus significantly improve the durability and reliability of the metal sheet of the air conditioner.

[0030] Reference Figures 1 - 3 , the outer corners of the secondary support steel member 4 and the main composite steel plate 1 are both set as arc-shaped. The overall shapes of the longitudinal outer support bars 42 and the transverse outer support bars 43 are set as side-rail isosceles trapezoids. Setting the outer corners of the secondary support steel member 4 and the main composite steel plate 1 as arc-shaped can effectively avoid accidental injuries that may be caused by sharp corners, reduce stress concentration, and enhance the impact resistance. The overall shapes of the longitudinal outer support bars 42 and the transverse outer support bars 43 are set as side-rail isosceles trapezoids, increasing the contact area, further improving the support effect, making the whole structure more stable when bearing external forces, and at the same time facilitating the uniform distribution of forces, reducing the possibility of damage caused by excessive local stress.

[0031] During the specific application period, various required raw materials can be prepared, including stainless steel, aluminum alloy, titanium alloy, transformation-induced plasticity steel, tungsten steel alloy, etc. For the stainless steel of the base layer 21, the required plate shape and thickness are made through rolling or casting processes. For the aluminum alloy of the heat conduction and dissipation layer 22, similar rolling or die-casting processes may be adopted and fixed on the stainless steel base layer 21 through welding, bonding or other appropriate connection methods. The titanium alloy support layer 23 and the transformation-induced plasticity steel outer layer 24 are also prepared through corresponding forming processes, such as welding, bonding, diffusion bonding or explosion bonding, and are sequentially connected to the previous layers. For the inner support frame 3 and the auxiliary support steel parts 4, components such as the transverse support strip 31, the longitudinal support strip 32, the outer support plate 41, the longitudinal outer support strip 42 and the transverse outer support strip 43 are first manufactured separately. These components can obtain blanks of tungsten steel alloy material through processes such as cutting, forging or casting, and then are machined, such as milling, grinding, etc., to achieve the required size and shape. Finally, the inner support frame 3 is fixed on the inner side of the main composite steel plate 1 through welding or bolt connection, etc., and the auxiliary support steel parts 4 are fixed on both sides of the main composite steel plate 1 through welding or bonding. During the processing, attention should be paid to controlling the connection quality and precision between layers to ensure the overall performance of the plate.

[0032] Principle of use and advantages: The stainless steel base layer 21 endows good corrosion resistance and stability, can effectively resist external erosion, and is not easy to rust and damage even after long-term use, greatly extending the service life of the metal plate. The heat conduction and dissipation layer of aluminum alloy has excellent heat conduction performance, can quickly conduct and dissipate the internal heat during the operation of the air conditioner, improve the refrigeration or heating efficiency, and reduce energy consumption. The titanium alloy support layer 23, with the characteristics of high strength and low density, provides strong support and stability for the metal plate, ensuring that it does not deform under complex working conditions and enhancing the overall structural strength and stability of the air conditioner. The transformation-induced plasticity steel outer layer 24 has both good strength and toughness, can effectively absorb the energy brought by external impacts, collisions and pressures, reduce the risk of deformation and damage, and has good forming performance, facilitating the manufacture of various shapes. For example, in harsh environments such as high temperature, high humidity and a lot of dust, the performance of this metal plate is still excellent; when the air conditioner operates at high load for a long time, it can ensure stable operation, safety and reliability.

[0033] The tungsten steel alloy has high strength, high hardness, good wear resistance and corrosion resistance. The transverse support bars 31, longitudinal support bars 32, outer support plates 41, longitudinal outer support bars 42 and transverse outer support bars 43 are all made of tungsten steel alloy, greatly enhancing the overall strength and stability of the air conditioner metal plate. The staggered arrangement of the transverse and longitudinal support bars 32 in the inner support frame 3, and the staggered arrangement of the longitudinal and transverse outer support bars 43 on the outside of the outer support plate 41 can evenly disperse the vibration and pressure generated during air conditioner operation, effectively reducing the risk of deformation and damage of the metal plate. The fixed connection between the outer support plate 41 of the auxiliary support steel part 4 and the main composite steel plate 1 further strengthens the structural stability of the metal plate. The external corners are set to be rounded, which can avoid accidental injuries caused by sharp corners, reduce stress concentration, and improve the impact resistance of the metal plate. The isosceles trapezoid shape design of the longitudinal outer support bar 42 and the transverse outer support bar 43 increases the contact area and improves the support effect, making the metal plate more stable when bearing external forces. In short, this technical solution can significantly improve the durability, safety and stability of the air conditioner metal plate, ensuring the reliable operation of the air conditioner under various environments and working conditions.
