During operation, vibrations from the evaporator body, particularly those caused by the fan or refrigerant flow, are transmitted through the evaporator bracket to the evaporator drain pan and air conditioner casing, generating mechanical resonance and noise. During vibration, the evaporator bracket and evaporator drain pan cause multiple damping particles in the first damping particles and multiple damping particles in the second damping particles to move. This energy is dissipated through collision and friction between the multiple damping particles and between the damping particles and the inner wall of the cavity, achieving vibration and noise reduction effects on the evaporator bracket and evaporator drain pan. By designing a particle damper consisting of a cavity and a damping particle group in the evaporator bracket and evaporator drain pan, the impact of vibration on the equipment can be significantly reduced, thereby extending the equipment's service life and reducing the frequency of repairs and component replacements. The introduction of particle dampers offers superior vibration reduction compared to traditional elastic materials, particularly in attenuating low- and medium-frequency vibrations. The internal friction of the damping particles allows them to efficiently absorb vibration energy and convert it into heat, significantly reducing noise and vibration during equipment operation and providing a more stable working environment.

[0055] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connected," "in contact," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0056] The evaporator bracket and evaporator water tray are part of the evaporator assembly in the air conditioner. Their main function is to support the evaporator and guide the discharge of condensed water. As the evaporator components operate, they will generate certain vibrations during operation. These vibrations are not only easy to transmit and cause noise problems, but may also cause certain damage to the equipment, affecting the long-term stability and operating efficiency of the equipment. However, there are no vibration reduction measures for the evaporator bracket and evaporator water tray in the existing technology.

[0057] Based on this, the following embodiments are proposed:

[0058] Example 1

[0059] like Figure 1-10As shown, this embodiment provides an evaporator assembly, comprising:

[0060] Evaporator bracket 1;

[0061] The evaporator water receiving tray 3 is arranged at the bottom of the evaporator bracket 1;

[0062] A first cavity 101 is formed on the evaporator support 1 , and a plurality of first damping particles 2 are filled in the first cavity 101 , which is configured as a first particle damper for reducing vibration of the evaporator support 1 ;

[0063] And / or, a second cavity 301 is formed on the evaporator water receiving tray 3 , and a plurality of second damping particles 4 are filled in the second cavity 301 , which is configured as a second particle damper for reducing vibration of the evaporator water receiving tray 3 .

[0064] The evaporator assembly provided in this embodiment is designed to reduce vibration for the evaporator bracket 1 and the evaporator water receiving pan 3. A first cavity 101 is formed on the evaporator bracket 1, and the first cavity 101 is filled with first damping particles 2. A second cavity 301 is formed on the evaporator water receiving pan 3, and the second cavity 301 is filled with second damping particles 4. The evaporator assembly can be used in an indoor unit of an air conditioner. When the evaporator body is in operation, especially the vibration caused by the fan or the flow of refrigerant, will be transmitted to the evaporator water receiving pan 3 and the air conditioner casing through the evaporator bracket 1, generating mechanical resonance and noise. During the vibration process of the evaporator bracket 1 and the evaporator water receiving pan 3, the multiple first damping particles 2 and the multiple second damping particles 4 are moved, and then the collision and friction between the multiple damping particles and between the damping particles and the inner wall of the cavity are utilized to consume energy, thereby achieving the vibration and noise reduction effect of the evaporator bracket 1 and the evaporator water receiving pan 3.

[0065] By arranging damping particles inside the evaporator bracket 1 and the evaporator water receiving tray 3, the damping particles can move freely in the cavity in which they are located under the action of external force, and effectively absorb and attenuate vibration energy through internal friction during the operation and vibration of the evaporator; preferably, the damping particles are one or more of rubber-coated steel or rubber particles, and the rubber particles can be silicone particles or TPE particles.

[0066] When the evaporator bracket 1 and the evaporator water tray 3 vibrate, the damping particles in the cavity absorb and dissipate the vibration energy through their dynamic interaction, effectively reducing the vibration amplitude and improving the vibration reduction performance. The movement of the damping particles in the cavity involves a variety of energy loss mechanisms, which involve complex physical processes. The first is the collision process between the damping particles and between the damping particles and the inner wall of the cavity, which not only generates heat energy dissipation, but also involves energy conversion and dissipation caused by elastic and inelastic collisions. Secondly, the friction generated by the relative sliding between the damping particles also leads to energy loss. The degree of this loss is affected by factors such as the particle material, surface state and contact pressure. In addition, since the interaction of the damping particles is not limited to a single direction, it can provide a damping effect in multiple directions, which is particularly suitable for slowing down complex vibrations, such as vibration suppression in three-dimensional space.

[0067] When the air conditioner starts operating, the generated mechanical vibrations are transmitted through the evaporator bracket 1 and the evaporator drain pan 3 to the damping particles within the cavity. The movement of the damping particles creates resistance within the cavity, and through friction and collision with the inner wall of the cavity, further attenuates the vibrations. During this process, the damping particles displace when affected by vibrations, which is then converted into heat energy through friction and collision, effectively consuming the vibration energy and reducing the vibration amplitude. The movement of the damping particles within the cavity effectively absorbs vibrations of different frequencies and intensities, resulting in a significant vibration reduction effect across all frequency bands.

[0068] Furthermore, a first cavity 101 is formed on the evaporator support 1, which is filled with first damping particles 2. A second cavity 301 is formed on the evaporator drain pan 3, which is filled with second damping particles 4. In this design, the damping particles can adapt to changes in vibration under different workloads and operating conditions. For example, when the workload of the evaporator support 1 and the evaporator drain pan 3 increases and the vibration intensity intensifies, the fluidity and mutual collision of the damping particles will generate greater frictional and collision energy dissipation, absorbing more energy. However, when the workload is lighter, the damping effect of the damping particles will be reduced accordingly, maintaining system stability. The adaptive adjustment capability of the damping particles ensures that the particle damper composed of the cavity and damping particle group can provide a continuous and stable vibration reduction effect in various environments and operating conditions. Therefore, by arranging the damping particle group in the cavity in combination with the evaporator bracket 1 and the evaporator water receiving tray 3, the damping effect can be automatically adjusted according to the frequency and intensity of the evaporator vibration, ensuring that the vibration reduction performance remains stable under different working conditions, and effectively reducing the vibration and noise generated during operation, thereby improving the stability and comfort of the equipment and extending the service life of the air conditioner.

[0069] During long-term operation, vibrations in air conditioner indoor units can cause friction, loosening, or fatigue between components, accelerating equipment aging. Designing a particle damper, consisting of a cavity and a group of damping particles, within the evaporator bracket 1 and evaporator drain pan 3 significantly reduces the impact of vibration on the equipment, thereby extending its service life and reducing the frequency of repairs and component replacements.

[0070] The introduction of particle dampers offers superior vibration reduction compared to traditional elastic materials, particularly in attenuating low- and medium-frequency vibrations. The internal friction of the damping particles allows them to efficiently absorb vibration energy and convert it into heat, significantly reducing noise and vibration during equipment operation and providing a more stable working environment.

[0071] By effectively reducing the vibrations generated during evaporator operation, particle dampers alleviate mechanical fatigue, prevent damage to components caused by continuous vibration, and extend the life of the equipment. The effective attenuation of vibration energy significantly reduces the impact forces on various equipment components, reducing wear and damage caused by fatigue and significantly improving the durability of the equipment.

[0072] In this embodiment, in the evaporator assembly, suitable damping particle sizes and materials can be selected according to the specific vibration characteristics of the evaporator bracket 1 and the evaporator water tray 3, so as to achieve the best vibration reduction effect in a targeted manner.

[0073] By designing a particle damper consisting of a cavity and a damping particle group in the evaporator bracket 1 and the evaporator water tray 3, the damping particles can maintain good vibration damping performance during long-term use and are not easily invalidated due to changes in ambient temperature and humidity.

[0074] In the evaporator assembly, since the particle damper is locally arranged, the material consumption is small, the installation is simple, and the overall cost is low.

[0075] In the evaporator assembly, a particle damper is locally provided to reduce vibration transmission between the evaporator bracket 1 and the evaporator water receiving pan 3, thereby improving the operating stability of the entire air-conditioning system.

[0076] The evaporator assembly proposed in this embodiment is further described below:

[0077] (1) Evaporator bracket, such as Figure 1-3 shown

[0078] The evaporator is a crucial component of a cabinet air conditioner, responsible for cooling the air and removing moisture. During operation, the evaporator and its supporting structure may experience vibrations due to airflow disturbances and the flow of refrigerant. This vibration can increase over time due to loosening of the evaporator bracket or aging of components, impacting the air conditioner's operational stability.

[0079] (2) Evaporator water tray, such as Figure 4-8 shown

[0080] During the operation of a cabinet air conditioner, condensed water on the evaporator surface is collected and drained through the evaporator drain pan. If the evaporator drain pan is not designed with effective vibration control in mind, the vibration of the water flow will not only cause noise but may also have a negative impact on other parts of the air conditioner.

[0081] (3) Particle dampers, such as Figure 3 、 5 -8 shown

[0082] A particle damper consisting of a cavity and a group of damping particles is designed in the evaporator bracket 1 and the evaporator water tray 3. A first cavity 101 is provided in the evaporator bracket 1, and a second cavity 301 is provided in the evaporator water tray 3. Both the first cavity 101 and the second cavity 301 are filled with damping particles. The damping particles can be rubber particles, polyurethane particles, silicone particles, etc., and the required particles must have high elasticity and strong internal friction properties. Preferably, the damping particles are added to the cavities during the component manufacturing process. The first cavity 101 is a closed cavity structure integrally formed with the evaporator bracket 1, and the second cavity 301 is a closed cavity structure integrally formed with the evaporator water tray 3.

[0083] When the evaporator bracket 1 and evaporator drain pan 3 vibrate, the movement of the damping particles within the cavity generates internal friction and collisions, which are converted into heat energy, thereby dissipating the vibration energy and reducing the vibration amplitude. The fluidity of the damping particles allows the damping effect to automatically adjust with changes in vibration frequency and intensity, ensuring the system's vibration reduction effect under various operating conditions.

[0084] (4) Monitoring system

[0085] Vibration sensors can be installed on the evaporator bracket 1 and the evaporator water tray 3 to monitor their vibration in real time. The particle damper is designed based on the actual vibration conditions of the evaporator bracket 1 and the evaporator water tray 3 to achieve the best vibration reduction effect.

[0086] In summary, the evaporator bracket plays a crucial supporting role in the air conditioner. The vibration generated by the evaporator is transmitted to the air conditioner casing and other components through the bracket. By introducing a particle damper into the evaporator bracket, the propagation of vibration can be reduced through the damping effect. The damping effect here includes viscous damping and friction damping, both of which effectively dissipate vibration energy through the distribution and contact of the damping particles.

[0087] The evaporator drain pan is the part of the air conditioner that drains condensed water, preventing it from overflowing or stagnating. Vibration issues with the evaporator drain pan primarily arise from the disturbance of the water flow and the flow of condensed water. This turbulence can exacerbate vibration, especially in high-speed air conditioners.

[0088] By introducing a particle damper into the evaporator's drain pan, positioned close to where condensate drips, the particles increase resistance to fluid flow through viscous and frictional damping. This reduces water velocity, reduces disturbances within the evaporator's drain pan, and thus reduces noise caused by water vibration. According to the principles of hydraulic mechanics, water flowing over irregular surfaces tends to generate turbulence. This turbulence not only generates noise but can also affect the flow's stability. By slowing the water flow and reducing turbulence, the damping particles can significantly reduce noise and improve air conditioner operation stability.

[0089] Alternatively, as Figure 1-3 As shown, in one implementation of this embodiment,

[0090] The evaporator support 1 includes a main frame 102 , and the main frame 102 has a first end frame 103 and a second end frame 104 that are oppositely arranged;

[0091] The first cavity 101 is formed in the first end frame 103 and / or the second end frame 104 .

[0092] In this embodiment, the main frame 102 is used to fix the main part of the evaporator, and the first end connecting frame 103 and the second end connecting frame 104 are respectively used to fix the two ends of the evaporator. By setting the first cavity 101 on the first end connecting frame 103 and / or the second end connecting frame 104, the first end connecting frame 103 and / or the second end connecting frame 104 are targetedly reduced in vibration.

[0093] Preferably, the first cavity 101 is provided with a plurality of;

[0094] The plurality of first cavities 101 are spaced apart and integrally formed in the first end frame 103;

[0095] And / or, a plurality of first cavities 101 are spaced apart and integrally formed within the second end frame 104. This design makes the first particle damper easy to form and simple in structure, and can be formed in a simple and compact manner on the frame portion of the evaporator support 1, without excessively increasing the load-bearing capacity of the frame and without occupying space on the frame.

[0096] Preferably, a portion of the plurality of first cavities 101 is formed on the first end connection frame 103 , and another portion of the plurality of first cavities 101 is formed on the second end connection frame 104 .

[0097] The design position of the first cavity 101 can more effectively block the critical path of vibration transmission on the evaporator bracket 1 .

[0098] The upper end of the evaporator bracket 1, i.e., the first end connecting frame 103, is usually connected to the air conditioner casing or the fixed frame, and the lower end, i.e., the second end connecting frame 104, is connected to the evaporator water receiving pan 3. By arranging a particle damper composed of a first cavity 101 and a plurality of first damping particles 2 at two locations, the vibration can be directly cut off from the vibration source, such as the compressor and the fan, through the evaporator bracket 1 to the evaporator and the evaporator water receiving pan 3, so that the vibration reduction effect is better.

[0099] If the vibration of the main frame 102 is reduced, the vibration can still be transmitted to the evaporator and the casing through the two ends of the evaporator bracket 1, and the vibration reduction effect is limited. If only the upper end or the lower end of the evaporator bracket 1 is reduced, it may cause residual unidirectional vibration (such as the fan vibration is still transmitted through the lower end); by arranging particle dampers at both ends of the evaporator bracket 1, a synergistic vibration reduction effect is achieved.

[0100] The design position of the first cavity 101 disperses vibration energy, preventing resonance in the evaporator support 1. Particle dampers at the upper and lower ends of the evaporator support 1 form a dual isolation layer, dispersing vibration energy and preventing failure of a single damping point due to overload. For example, the particle damper at the upper end absorbs external vibration, while the particle damper at the lower end suppresses vibration of the evaporator support 1 itself.

[0101] The design position of the first cavity 101 can suppress the resonant frequency. The natural frequency of the evaporator bracket 1 may resonate due to the length or material matching the vibration source. The particle dampers at both ends of the cavity can change the natural frequency of the evaporator bracket 1 to avoid the resonant range.

[0102] The design position of the first cavity 101 can improve the structural stability. Particle dampers are set at both ends of the evaporator bracket 1, which can not only alleviate vibration impact, but also maintain the rigid support function of the evaporator bracket 1, preventing the evaporator bracket 1 from reducing its strength due to more cavities.

[0103] Alternatively, as Figure 4-10As shown, in one implementation of this embodiment,

[0104] The evaporator water receiving tray 3 is provided with a connecting piece 303, and the connecting piece 303 is used to connect with the evaporator;

[0105] The second cavity 301 is formed in the connecting member 303 .

[0106] In this embodiment, the connecting member 303 is used to connect the evaporator water receiving pan 3 and the evaporator, and the vibration generated by the evaporator during operation is directly transmitted to the evaporator water receiving pan 3 through the connecting member 303. By arranging a second particle damper on the connecting member 303, the second particle damper can more specifically reduce the vibration of the evaporator water receiving pan 3, that is, the second particle damper can be affected by the vibration generated by the operation of the evaporator and transmitted to the evaporator water receiving pan 3 earlier and faster. In the evaporator assembly, by arranging a second particle damper on the connecting member 303, the vibration transmission between the evaporator and the evaporator water receiving pan 3 can be more efficiently reduced, thereby improving the operating stability of the entire air-conditioning system.

[0107] Alternatively, as Figure 4-10 As shown, in one implementation of this embodiment,

[0108] The evaporator water receiving tray 3 is formed with a water tank 302 , and the portion of the connecting member 303 having the second cavity 301 is located in the water tank 302 .

[0109] In this embodiment, by positioning the portion of the connector 303 containing the second cavity 301 within the water tank 302, i.e., the second particle damper is located both on the connector 303 and within the water tank 302, not only can the vibration transmission between the evaporator and the evaporator water tray 3 be reduced, but also, through viscous damping and frictional damping, the particle damping increases the resistance to fluid flow, resulting in a decrease in water flow velocity, reducing disturbances in the water flow within the water tank 302, and thus reducing noise caused by water flow vibration. According to the principles of hydraulic mechanics, water flowing over irregular surfaces is prone to turbulence. This turbulence not only generates noise but can also affect the stability of the water flow. By slowing the water flow and reducing the turbulence generated by the water flow, the damping particles can significantly reduce noise and improve the operational stability of the air conditioner.

[0110] Alternatively, as Figure 4-10 As shown, in one implementation of this embodiment,

[0111] The second cavity 301 is provided with a plurality of;

[0112] The connecting member 303 includes a first connecting portion 3031 and a second connecting portion 3032 connected to the first connecting portion 3031 , wherein the first connecting portion 3031 is located in the water tank 302 , and the second connecting portion 3032 is used to connect to the evaporator;

[0113] The plurality of second cavities 301 are spaced apart and integrally formed in the first connecting portion 3031 .

[0114] In this embodiment, one end of the first connecting portion 3031 is integrally connected to one end of the second connecting portion 3032. The other end of the first connecting portion 3031 extends within the water tank 302, increasing the connection area between the connecting member 303 and the water tank 302, making the connection more secure and providing ample molding space for the second cavity 301. The other end of the second connecting portion 3032 extends vertically upward and is provided with a threaded hole at its end for easy connection to the evaporator. The first connecting portion 3031 and the second connecting portion 3032 form an L-shaped connecting member 303, which not only establishes a secure connection between the evaporator water tray 3 and the evaporator, but also allows the second particle damper to be located both on the connecting member 303 and within the water tank 302, reducing vibration transmission between the evaporator and the evaporator water tray 3. Furthermore, the particle damping through viscous and frictional damping increases the resistance to fluid flow, resulting in a lower water flow velocity and reduced disturbances in the water tank 302, thereby reducing noise caused by water vibration. According to the principles of hydraulics, water flowing over irregular surfaces tends to generate turbulence, which not only produces noise but also can affect the stability of the flow. Damping particles slow the water flow and reduce turbulence, significantly reducing noise and improving the operating stability of air conditioners.

[0115] Alternatively, as Figure 4-10 As shown, in one implementation of this embodiment,

[0116] At least one cavity wall of the first cavity 101 is configured as an arc-shaped wall surface;

[0117] And / or, at least one cavity wall of the second cavity 301 is configured as an arc-shaped wall surface.

[0118] Preferably, the first cavity 101 is configured as a cylindrical cavity;

[0119] And / or, the second cavity 301 is configured as a cylindrical cavity.

[0120] In this embodiment, the cylindrical cavity may be a cylindrical cavity. The cylindrical cavity or the spherical cavity has uniform stress distribution when subjected to force, which can reduce stress concentration and improve the durability and deformation resistance of the first cavity 101 and the second cavity 301.

[0121] In terms of manufacturing technology, the processing of cylindrical cavities and spherical cavities is relatively simple, with low cost and high production efficiency. They are suitable for large-scale molding and are suitable for small space layout.

[0122] The damping particles are more easily evenly distributed in the cylindrical cavity and the spherical cavity, with less accumulation, thereby improving the damping effect.

[0123] The cylindrical cavity and the spherical cavity have good symmetry and high vibration transmission efficiency, which can promote particle friction and collision and improve damping efficiency.

[0124] In this embodiment, the position arrangement of the first cavity 101 on the evaporator bracket 1 and the position arrangement of the second cavity 301 on the evaporator water tray 3 can be designed to be asymmetric according to actual needs. For example, in order to avoid interference with other components of the air conditioner, the positions can be designed to be asymmetric.

[0125] Optionally, in one implementation of this embodiment,

[0126] The first cavity 101 is constructed as a cylindrical cavity, and the particle size of the first damping particles 2 is larger than one twentieth of the radius of the radial cross section of the first cavity 101 and smaller than one half of the radius of the radial cross section of the first cavity 101;

[0127] And / or, the second cavity 301 is constructed as a cylindrical cavity, and the particle size of the second damping particles 4 is larger than one twentieth of the radial cross-sectional radius of the second cavity 301 and smaller than one half of the radial cross-sectional radius of the second cavity 301 .

[0128] In this embodiment, if the volume of the damping particles is too small relative to the volume of the corresponding cavity, it may lead to overpacking, affecting freedom of movement. If it is too large, it may not effectively impact, reducing the damping effect. By designing the damping particle size to be between one-twentieth and one-half of the radial cross-section of the cavity, it is possible to ensure that the damping particles have sufficient space to move within the corresponding cavity, while achieving a high collision frequency and energy dissipation, thereby achieving a better damping effect.

[0129] Optionally, in one implementation of this embodiment,

[0130] The mass filling ratio of the first damping particles 2 in the first cavity 101 is 20% to 30%;

[0131] The mass filling ratio of the second damping particles 4 in the second cavity 301 is 20% to 30%.

[0132] In this embodiment, by optimizing the design of key parameters such as the material, size, shape, and filling rate of the damping particles, the performance of the particle damper can be significantly improved, and effective vibration control can be achieved in various environments.

[0133] The calculation method of the mass filling ratio of the first damping particles 2 in the first cavity 101 and the mass filling ratio of the second damping particles 4 in the second cavity 301 are the same: first, fill the cavity with damping particles, pour out all the damping particles and weigh them, repeat the filling and pouring process n times, calculate the average value of the damping particles n times, and calculate the mass of the damping particles after the cavity is filled with damping particles. If the mass of the damping particles is 500g, then the mass filling ratio of the first damping particles 2 in the first cavity 101 is 20%, that is, 500×0.2=100g, and the filling mass of the first damping particles 2 in the first cavity 101 is 100g.

[0134] In terms of damping particle material selection and design: Damping particle materials are chosen based on their vibration absorption capabilities. Common particle materials include rubber particles, polyurethane particles, silicone particles, and steel balls, which have strong elasticity and a certain degree of hardness. The size and filling ratio of the damping particles are optimized based on the operating frequency and vibration characteristics of the evaporator component to ensure effective vibration absorption within different frequency ranges.

[0135] The dimensionless vibration reduction ratio δ and noise reduction ratio ρ are introduced as evaluation indicators to determine the vibration suppression of the evaporator assembly by the particle damper composed of a cavity and a damping particle group.

[0136] in:

[0137]

[0138] Wherein, x1 and D1 are the displacement amplitude and the RMS noise of the evaporator assembly when the first cavity 101 and the second cavity 301 are not filled with damping particles; x2 and D2 are the RMS values ​​of the displacement amplitude and the noise of the evaporator assembly when the first cavity 101 and the second cavity 301 are filled with damping particles.

[0139] The first simulation condition was set up, keeping the particle size and other parameters constant. The energy consumption was compared when the damping particle mass filling ratio was 10%, 15%, 20%, 25%, and 30%. The simulation results were processed to obtain Table 1.

[0140] Table 1 Energy consumption at different filling ratios

[0141]

[0142]

[0143] From the comparison results in Table 1, it can be seen that the mass filling ratio of the first damping particles 2 in the first cavity 101 is 20% to 30%, and the mass filling ratio of the second damping particles 4 in the second cavity 301 is 20% to 30%, which has obvious advantages over the vibration reduction ratio and noise reduction ratio with a mass filling ratio of 10% and 15%. As for the vibration reduction ratio and noise reduction ratio, they are selected according to specific needs. For example, if the evaporator component is designed to focus on vibration reduction, the filling ratio of the damping particles in the corresponding cavity can be selected to be 20% to 25%. If the evaporator component is designed to focus on noise reduction, the filling ratio of the damping particles in the corresponding cavity can be selected to be 25% to 30%.

[0144] The comparison results in Table 1 also show that the mass filling ratio shows a trend of first increasing and then decreasing, with the vibration and noise reduction ratios reaching their peak values ​​at a mass filling ratio of 20% to 25%. When the mass filling ratio is small, the probability of collision and friction between the damping particles and the cavity is low due to the small number of particles in the cavity. However, when the mass filling ratio exceeds 20% to 25%, although the number of damping particles in the cavity increases, the number of damping particle accumulation layers increases, the movement space of the damping particles decreases, and the movement of the damping particles in the lower layer is restricted by the gravity of the damping particles in the upper layer, resulting in a decrease in the total energy consumption of the particle damping.

[0145] Preferably, the particle size of the first damping particles 2 is 1.0 mm to 3.0 mm;

[0146] And / or, the particle size of the second damping particles 4 is 1.0 mm to 3.0 mm.

[0147] A second simulation condition was set up, keeping parameters such as the damping particle mass filling ratio constant. Energy consumption was compared for damping particle sizes of 0.5 to 1.0 mm, 1.0 to 1.5 mm, 1.5 to 2.0 mm, 2.0 to 2.5 mm, 2.5 to 3.0 mm, and 3.0 to 3.5 mm. The simulation results were processed to produce Table 2.

[0148] Table 2 Effect of different damping particle sizes on energy consumption

[0149]

[0150] From the comparison results in Table 2, it can be seen that when the particle size of the damping particles is 1.0mm to 3.0mm, the vibration reduction ratio and noise reduction ratio have obvious advantages compared with those in other particle size ranges. As for the vibration reduction ratio and noise reduction ratio, they should be selected according to specific needs.

[0151] From the comparison results in Table 2, it can be seen that the vibration reduction ratio and the noise reduction ratio first increase and then decrease as the particle size of the damping particles increases. As the particle size increases, the number of damping particles in the cavity becomes smaller and smaller, which reduces the number of frictional contacts between the damping particles and the inner wall of the cavity, resulting in smaller energy consumption, vibration reduction ratio, and noise reduction ratio.

[0152] Alternatively, as Figure 11-15 As shown, in one implementation of this embodiment,

[0153] The plurality of first damping particles 2 in the first particle damper have different shapes, and / or different particle sizes, and / or different masses, and / or different materials;

[0154] And / or, the plurality of second damping particles 4 in the second particle damper have different shapes, and / or different particle sizes, and / or different masses, and / or different materials.

[0155] Preferably, the multiple first damping particles 2 in the first particle damper have different shapes, selected from a combination of at least two of spherical, lamellar, ellipsoidal or conical shapes; the multiple second damping particles 4 in the second particle damper have different shapes, selected from a combination of at least two of spherical, lamellar, ellipsoidal or conical shapes.

[0156] In this embodiment, Figure 11 The figure shows a schematic diagram of a simulation model in which multiple first damping particles 2 are located in a first cavity 101. The multiple first damping particles 2 in the first particle damper have different shapes, including: shape 1 is a spherical damping particle, shape 2 is a lamellar damping particle, shape 3 is an ellipsoidal damping particle, and shape 4 is a conical damping particle. The same applies to the multiple second damping particles 4 in the second particle damper.

[0157] The plurality of first damping particles 2 are composed of a mixture of particles of regular shape and irregular shape, and the plurality of second damping particles 4 are composed of a mixture of particles of regular shape and irregular shape, thereby enhancing the vibration reduction effect through multiple collisions and frictions between the damping particles.

[0158] The above design makes it easier for multiple damping particles to move irregularly when they rub and collide, and this fluctuation is particularly obvious at the initial start-up, such as Figure 12 The figure shows the motion state of the damping particles in the first cavity 101. During the whole process, the energy consumption generated by friction damping and collision damping increases with time. However, in the initial startup period (0s to 0.3s), the movement of the damping particles causes the friction energy consumption and collision energy consumption of the damping particles to show a certain irregularity due to the friction force with the first cavity 101 (the damping particle velocity scale is shown in FIG. Figure 12The bar diagram on the left side of the middle diagram shows that different damping particle colors represent different particle movement speeds), which leads to certain fluctuations in the overall energy consumption. Figure 13 This is a schematic diagram of the damping particle distribution at a certain moment under this working condition. Figure 14 is a schematic diagram of the velocity vector of the damping particles at this moment under this working condition; after 0.3s, if Figure 15 As shown, as the movement of the damping particles in the first cavity 101 shows a certain regularity, the changes of their friction energy consumption and collision energy consumption over time also show a corresponding linear law.

[0159] In summary, the ingenious concept of the evaporator assembly in this application is:

[0160] First, a vibration reduction design is implemented for the evaporator bracket and evaporator drain pan. A first cavity is formed on the evaporator bracket, which is filled with first damping particles. A second cavity is formed on the evaporator drain pan, which is filled with second damping particles. This evaporator assembly can be used in an air conditioner indoor unit. During operation, vibrations of the evaporator body, particularly those caused by the fan or refrigerant flow, are transmitted through the evaporator bracket to the evaporator drain pan and the air conditioner casing, generating mechanical resonance and noise. During vibration of the evaporator bracket and evaporator drain pan, multiple damping particles in the first damping particles and multiple damping particles in the second damping particles move. This energy is dissipated through collision and friction between the multiple damping particles and between the damping particles and the inner wall of the cavity, achieving vibration and noise reduction effects on the evaporator bracket and evaporator drain pan. By designing a particle damper consisting of a cavity and a damping particle group in the evaporator bracket and evaporator drain pan, the impact of vibration on the equipment can be significantly reduced, thereby extending the equipment's service life and reducing the frequency of repairs and component replacements. The introduction of particle dampers offers superior vibration reduction compared to traditional elastic materials, particularly in attenuating low- and medium-frequency vibrations. The internal friction of the damping particles allows them to efficiently absorb vibration energy and convert it into heat, significantly reducing noise and vibration during equipment operation and providing a more stable working environment.

[0161] Second, the design position of the first cavity can more effectively block the key path of vibration transmission on the evaporator bracket. The upper end of the evaporator bracket, that is, the first end connecting frame, is usually connected to the air-conditioning casing or the fixed frame, and the lower end, that is, the second end connecting frame, is connected to the evaporator water collecting pan. By arranging the particle damper composed of the first cavity and the first damping particle group at two places, the vibration can be directly cut off from the vibration source, such as the compressor and the fan, through the evaporator bracket to the evaporator and the evaporator water collecting pan. The transmission path can be better.

[0162] Third, by introducing particle dampers at specific locations within the evaporator's water tray—a second particle damper located both on the connector and within the water tank—the damper not only reduces vibration transmission between the evaporator and the water tray, but also, through viscous and frictional damping, increases resistance to fluid flow, reducing water velocity and disturbances within the water tank, thereby minimizing noise caused by water vibration. By slowing water flow and reducing turbulence, the damping particles significantly reduce noise and enhance air conditioner operation stability.

[0163] Fourth, by optimizing the design of key parameters such as the damping particle material, size, shape, and fill ratio, the performance of the particle damper can be significantly improved, achieving effective vibration control in a variety of environments. Regarding the selection and design of the damping particle material: The damping particle material is chosen based on its vibration absorption capacity. Common particle materials include rubber particles, polyurethane particles, silicone particles, and steel balls, which have strong elasticity and a certain degree of hardness. The size and fill ratio of the damping particles are optimized based on the operating frequency and vibration characteristics of the evaporator component to ensure effective vibration absorption across different frequency ranges.
