Description

Technical Field

[0001] This application relates to the field of compressors, and particularly to a compressor assembly, an air-conditioning system, and a vehicle. Background Art

[0002] A compressor is a mechanical device used to increase gas pressure. During the operation of a compressor, due to factors such as the interaction of internal mechanical structures and gas flow, vibrations and noises will inevitably occur. And when the self-excitation frequency of the compressor is the same as or close to the natural frequency of the compressor, or the self-excitation frequency of the compressor matches the vibration frequency of any external excitation, resonance may occur, and the resonance will further amplify the vibrations and noises of the compressor. Summary of the Utility Model

[0003] In view of this, embodiments of this application provide a compressor assembly, an air-conditioning system, and a vehicle, which are used to solve the technical problem of large vibrations and noises during the operation of the compressor in related technologies.

[0004] An embodiment of the first aspect of this application provides a compressor assembly, including a compressor and a particle damper. The compressor includes a housing, and the particle damper is disposed on the outer wall of the housing. The particle damper includes a box body and damping particles. The box body has a cavity inside, and the damping particles are movably disposed in the cavity.

[0005] In the compressor assembly provided by the embodiments of this application, a particle damper is disposed on the outer wall of the housing of the compressor. The particle damper includes a box body and damping particles movably disposed in the cavity of the box body. During the vibration of the compressor, the particle damper is driven to vibrate together. As the particle damper vibrates, the damping particles inside the box body collide and rub against each other and against the cavity wall. These collisions and frictions can convert and dissipate part of the vibration energy, thereby weakening the vibration energy of the compressor, reducing the amplitude of the compressor, and achieving the vibration reduction effect. Particularly, in the case of resonance, the particle damper can suppress the vibration of the compressor, reducing the peak value of the resonance amplitude of the compressor. As the vibration of the compressor and the compressor assembly weakens, the noise generated by the vibration and the noise peak value also weaken accordingly.

[0006] In some embodiments, the box body is attached to the housing. In the above design, there is good physical contact and an energy transfer path between the compressor and the particle damper, and the particle damper can exert its vibration reduction efficiency to the greatest extent.

[0007] In some embodiments, the housing includes a main body portion and an end cap assembled on the main body portion, and the box body is disposed on the main body portion or on the end cap. In the above design, the box body is disposed on the main body portion, and the setting position is relatively flexible, which is beneficial to improving the overall compactness of the compressor assembly; the box body is disposed on the end cap, which can better absorb the vibration energy at the end cap, thereby reducing the wear of the parts at the end cap position and having a good heat dissipation effect.

[0008] In some embodiments, the compressor assembly further includes a fastener for fixing the box body to the housing. In the above design, the fastener can provide a stable and reliable mechanical connection, so that during the operation of the compressor, the particle damper is not easily loosened.

[0009] In some embodiments, the box body includes a first side wall and a second side wall disposed opposite to each other, and there is an installation channel between the first side wall and the second side wall for installing the fastener and penetrating the cavity. In the above design, the installation channel can provide an accurate installation position, reduce the assembly difficulty between the compressor and the particle damper, and the installation channel can better disperse the pressure transmitted by the fastener, reducing the risk of damage to the box body.

[0010] In some embodiments, an installation hole is provided on the side wall of the housing, and the installation hole is disposed opposite to the installation channel for installing the fastener. In the above design, the fastener passes through the installation channel and is connected to the installation hole, and the assembly difficulty is relatively low.

[0011] In some embodiments, an installation post protrudes from the outer wall of the housing, and the installation post is inserted into the installation channel, and an installation hole for installing the fastener is provided in the installation post. In the above design, the plug-in fit structure between the installation post and the installation channel can reduce the relative displacement between the compressor and the particle damper during vibration, thereby ensuring the vibration damping effect of the particle damper.

[0012] In some embodiments, there is a cavity in the box body. In the above design, the damping particles have a higher degree of freedom in the cavity, the damping particles can respond to the vibration of the compressor in a timely manner, and the collision and friction between the damping particles are more intense, which is beneficial to the rapid dissipation of vibration energy.

[0013] In some embodiments, there are multiple cavities in the box body. In the above design, the particle damper has higher versatility.

[0014] In some embodiments, the filling rate of the damping particles in the cavity is 50%-90%. In the above design, the filling rate range of the damping particles is reasonable and has good vibration damping performance.

[0015] In some embodiments, the damping particles are spherical particles, and the diameter of the damping particles is 0.1 mm - 10 mm. In the above design, the size of the damping particles is reasonable, which can ensure the contact area and collision effect between the damping particles and between the damping particles and the cavity wall.

[0016] In some embodiments, the mass of the particle damper is 2%-5% of the mass of the compressor. In the above design, the mass range of the particle damper is reasonably set. The particle damper can effectively suppress the vibration of the compressor, and the overall stability of the compressor assembly is relatively high.

[0017] In some embodiments, the damping particles are metal particles. In the above design, the metal particles have good wear resistance, can withstand large vibrations and have good vibration damping effects.

The phrase appearing at various positions in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0041] In the description of the embodiments of this application, unless otherwise clearly specified and limited, technical terms such as "installation", "connection", "connection", "fixation", etc. should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may also be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements or the interaction relationship between two elements.

[0042] The compressor is the core component of the automotive air conditioning system, and its function is to compress and transport the refrigerant to achieve the temperature adjustment of the vehicle interior environment. During the operation of the compressor, due to the interaction of the internal mechanical structure and factors such as gas flow during the compression process, vibration and noise will be generated. In new energy vehicles, due to the lack of the masking effect of engine vibration and noise, the vibration and noise problems of the compressor are more prominent.

[0043] To alleviate the vibration and noise problems of the compressor, a rubber gasket can be provided between the compressor and the mounting bracket of the compressor. By utilizing the elastic absorption characteristics of the rubber gasket, the vibration and noise of the compressor can be reduced. Moreover, the rubber gasket isolates the compressor from the mounting bracket and can also weaken the vibration transmission to the vehicle body. In practical applications, the presence of the rubber gasket endows the compressor with six degrees of freedom, and each degree-of-freedom mode has its corresponding natural frequency. In order to ensure the vibration damping effect of the rubber gasket, the natural frequency is required to be maintained at a relatively low level.

[0044] When conducting a range test on a new energy vehicle, strict requirements are imposed on the rotational speed of the compressor. Specifically, since the operation of the compressor consumes energy and the energy consumption increases with the increase in rotational speed, in order to optimize the driving distance of the vehicle during the range test, the rotational speed of the compressor needs to be maintained at a low level. Under this background, when the compressor operates at a low speed, its own excitation frequency may approach or fall within the frequency range of the compressor's rigid body mode, thereby triggering resonance, and resonance will further amplify the vibration and noise of the compressor, making the vehicle's Noise, Vibration, Harshness (NVH) problems more prominent.

[0045] To improve the vibration and noise problems of the compressor, an embodiment of the present application provides a compressor assembly, including a compressor and a particle damper. The particle damper is disposed on the outer wall of the housing of the compressor. The particle damper includes a box body and damping particles movably disposed in the cavity of the housing. When the compressor vibrates, the vibration can be transmitted to the particle damper, causing the particle damper to vibrate together with the compressor. As the box body of the particle damper moves, the damping particles disposed in the cavity of the box body will collide with the cavity wall, and the damping particles will also collide with each other. These collisions can convert part of the vibration energy into heat energy, thereby weakening the vibration energy of the compressor, reducing the vibration of the compressor and the peak value of the amplitude, and achieving the vibration damping effect. In the case of resonance, the particle damper can suppress the vibration of the compressor, thereby effectively reducing the peak value of the amplitude of the compressor during resonance. As the vibration of the compressor and the compressor assembly weakens, the noise and the peak value of the noise generated by the vibration also weaken accordingly.

[0046] The compressor assembly disclosed in the embodiment of the present application can be used in vehicles, spacecraft, household appliances, industrial equipment, medical equipment, food processing equipment, etc. Spacecraft include airplanes, rockets, space shuttles, and spaceships, etc.; household appliances include air conditioners, refrigerators, dehumidifiers, etc.; industrial equipment includes sandblasters, pneumatic drills, spray guns, etc.; medical equipment includes ventilators, atomizers, etc.; food processing equipment includes freezers, sealing machines, food cleaning machines, etc.

[0047] For the convenience of description, the following embodiments will be described by taking the vehicle 1000 provided in an embodiment of the present application as an example.

[0048] Please refer to Figure 1 , Figure 1 which is a schematic structural diagram of the vehicle 1000 provided in some embodiments of the present application. The vehicle 1000 can be a fuel vehicle, a gas vehicle, or a new energy vehicle. The new energy vehicle can be a pure electric vehicle, a hybrid vehicle, an extended-range vehicle, etc. A battery 100 is disposed inside the vehicle 1000, and the battery 100 can be disposed at the bottom, head, or tail of the vehicle 1000. The battery 100 can be used for power supply of the vehicle 1000. For example, the battery 100 can be used as the operating power source of the vehicle 1000. The vehicle 1000 can further include a controller 200 and a motor 300. The controller 200 is used to control the battery 100 to supply power to the motor 300. For example, it is used for the working power requirements during the start, navigation, and driving of the vehicle 1000.

[0049] A compressor assembly 10 is disposed inside the vehicle 1000, and the compressor assembly 10 can be disposed at the bottom or the front engine compartment of the vehicle 1000. Please refer to Figure 2 and Figure 3 , Figure 2 which is an assembly schematic diagram of the vehicle frame 400 and the compressor 11 provided in some embodiments of the present application, Figure 3 which is an assembly schematic diagram of the compressor 11 and the mounting bracket 500 provided in some embodiments of the present application. The vehicle 1000 further includes a vehicle frame 400 and a mounting bracket 500 disposed on the vehicle frame 400. The mounting bracket 500 is used to fix the compressor assembly 10. The mounting bracket 500 is arranged to avoid other moving parts of the vehicle 1000, such as the drive shaft and the steering system, so as to avoid movement interference during the operation of the vehicle 1000. The mounting bracket 500 can be fixed to the vehicle frame 400 by bolts. Vibration isolation pads, shock absorbers and other structures can be provided at the connection between the mounting bracket 500 and the vehicle frame 400 to reduce the vibration transmission from the mounting bracket 500 to the vehicle frame 400. The shape and size of the mounting bracket 500 are determined according to the structure of the compressor 11. Positioning holes or positioning grooves are preset on the mounting bracket 500. The compressor 11 can be fixed to the mounting bracket 500 by bolts and connecting rods. Structures such as a rubber gasket 20 are provided at the connection between the mounting bracket 500 and the compressor 11 to reduce the vibration transmission from the compressor 11 to the mounting bracket 500.

[0050] The following will describe the technical solutions provided in the embodiments of the present application with reference to the accompanying drawings. Figure 4 which is an exploded structural diagram of the compressor assembly 10 provided in an embodiment of the present application; Figure 5 is Figure 4 a cross-sectional view of the particle damper 12 in the compressor assembly 10 shown in the X direction; Figure 6Schematic exploded view of the compressor assembly 10 provided by another embodiment of the present application.

[0051] As Figure 4 shown in the figure, the X direction in the figure is defined as the length direction of the compressor 11, the Y direction is the width direction of the compressor 11, and the Z direction is the height direction of the compressor 11.

[0052] An embodiment of the first aspect of the present application provides a compressor assembly 10, including a compressor 11 and a particle damper 12. The compressor 11 includes a housing 111, and the particle damper 12 is disposed on the outer wall of the housing 111. The particle damper 12 includes a box body 121 and damping particles 123. The box body 121 has a cavity 122 inside, and the damping particles 123 are movably disposed in the cavity 122.

[0053] The housing 111 of the compressor 11 is generally designed as a closed structure, and its shape and size depend on the type, design, and application requirements of the compressor 11. The housing 111 is made of materials such as cast iron, aluminum alloy, or stainless steel. The housing 111 has a certain strength, can meet different pressure resistances, and provides necessary protection for the components inside the housing 111.

[0054] A compression mechanism, a motor, a transmission mechanism, an intake valve, an exhaust valve, a cooling system, and a lubrication system are disposed inside the housing 111 of the compressor 11. The compression mechanism is used to compress gas. Different types of compressors 11 correspond to different compression mechanisms. For example, the compression mechanism of a reciprocating compressor includes structures such as a cylinder, a piston, and a crankshaft. The compression mechanism of a rotary compressor includes structures such as a rotor, a stator, and a sliding vane. The compression mechanism of a scroll compressor includes structures such as a fixed scroll disk and a rotating scroll disk. The compression mechanism of a centrifugal compressor includes structures such as an impeller and a diffuser. The motor is used to provide power for the operation of the compressor 11, and the motor can be a DC motor or an AC motor. The transmission mechanism is used to convert the rotational motion of the motor into the working motion required by the compressor 11, and the transmission mechanism includes structures such as a crankshaft and a connecting rod. The intake valve and the exhaust valve are disposed on the pipeline and are used to control the inlet and outlet of gas. The cooling system is used for heat dissipation and includes structures such as pipes or fins with good heat conduction performance. The lubrication system is used to provide lubricating oil for the moving parts inside the compressor 11 to reduce the wear of the moving parts, and specifically includes structures such as an oil pump, an oil filter, and a sealing ring.

[0055] The box body 121 of the particle damper 12 is also the outer shell of the particle damper 12. The box body 121 is hollow inside and forms a closed cavity 122 structure. The box body 121 is used to accommodate the damping particles 123 and define the moving space of the damping particles 123. The shape and size of the box body 121 depend on the installation position and application requirements, and can be, for example, a square, cylindrical, or annular structure.

[0056] The damping particles 123 are generally small solid particles, which are filled in the cavity 122 of the box body 121 and can move or roll freely in the cavity 122. The shape, size, material, and filling amount of the damping particles 123 are determined according to application requirements. It should be noted that, Figure 5 The attached drawings shown are only used to illustrate the damping particles 123 arranged in the cavity 122 of the box body 121, rather than to limit the size, filling rate, and shape of the damping particles 123.

[0057] When the compressor 11 vibrates, it can drive the particle damper 12 arranged on its housing 111 to vibrate together. With the vibration of the box body 121 of the particle damper 12, the damping particles 123 arranged in the cavity 122 of the box body 121 also move together, and the damping particles 123 collide and rub against each other and against the cavity wall of the cavity 122.

[0058] In the above embodiment, the outer wall of the housing 111 of the compressor 11 is provided with a particle damper 12. The particle damper 12 includes a box body 121 and damping particles 123 movably arranged in the cavity 122 of the box body 121. During the vibration of the compressor 11, the particle damper 12 is driven to vibrate together. With the vibration of the particle damper 12, the damping particles 123 inside the box body 121 collide and rub against each other and against the cavity wall of the cavity 122. These collisions and frictions can convert and dissipate part of the vibration energy, thereby weakening the vibration energy of the compressor 11, reducing the amplitude of the compressor 11, and achieving the vibration damping effect. In particular, in the case of resonance, the particle damper 12 can suppress the vibration of the compressor 11, reducing the amplitude peak of the resonance of the compressor 11. As the vibration of the compressor 11 and the compressor assembly 10 weakens, the noise generated by the vibration and the noise peak also weaken accordingly.

[0059] In some embodiments, the box body 121 is attached to the housing 111.

[0060] The attached setting means that the two are in direct contact and tightly connected. The box body 121 is attached to the outer wall of the housing 111, and it is required that the shape of the box body 121 is adapted to the shape of the housing 111 at the installation position.

[0061] With the above design, there is a good physical contact and energy transfer path between the compressor 11 and the particle damper 12. Thus, the particle damper 12 can respond in a timely manner and absorb the vibration energy of the compressor 11, and can maximize the vibration damping efficiency of the particle damper 12.

[0062] It can be understood that in some other embodiments, the particle damper 12 can be indirectly installed on the compressor 11 through connecting parts such as a fixing frame, and there can be an installation gap between the particle damper 12 and the compressor 11.

[0063] In the embodiments provided in the present application, the housing 111 includes a main body portion 112 and an end cap 113 assembled on the main body portion 112, and the box body 121 is disposed on the main body portion 112 or the end cap 113.

[0064] The main body portion 112 is the core part of the housing 111 of the compressor 11, which is used to enclose an assembly space and provide a necessary installation foundation and sealing environment for the working elements of the compressor 11, such as a motor, a transmission mechanism, an intake valve, an exhaust valve, a cooling system, etc. The end cap 113 is a sealing component disposed at both ends of the main body portion 112, which is used to close the housing 111. The end cap 113 generally includes a front end cap and a rear end cap. In addition to the sealing function, the end cap 113 can also be used to install and fix the components of the compressor 11, such as installing and fixing bearings.

[0065] In some embodiments, as Figure 4 shown, the box body 121 is disposed on the main body portion 112.

[0066] On the one hand, the main body portion 112 is relatively large in volume, which can provide sufficient assembly space for the particle damper 12, and this setting method is more conducive to integrating the particle damper 12 into the overall structure, improving the compactness of the compressor assembly 10; on the other hand, the main body portion 112 directly encloses the main working elements of the compressor 11. The particle damper 12 disposed on the main body portion 112 can more directly respond to the vibrations of these working elements, thereby being able to exert its vibration damping performance.

[0067] In some embodiments, as Figure 6 shown, the box body 121 is disposed on the end cap 113.

[0068] On the one hand, the particle damper 12 disposed on the end cap 113 can better absorb the vibration energy at the end cap 113, thereby reducing the wear of the parts at the position of the end cap 113; on the other hand, the position of the end cap 113 is usually exposed, and the surface has a relatively large installation space. The particle damper 12 has a flexible installation position on the end cap 113 and has a better heat dissipation effect.

[0069] It should be noted that the specific installation position of the particle damper 12 on the main body portion 112 or the end cap 113 can be determined according to the vibration characteristics of the compressor 11, the structural characteristics of the compressor 11, and the assembly difficulty.

[0070] In some embodiments, the particle damper 12 is disposed at the position with the largest amplitude of the compressor 11. The "position with the largest amplitude" is a specific position where the displacement amount reaches the maximum due to vibration during the operation of the compressor 11. The position with the largest amplitude of the compressor 11 needs to be determined through processes such as vibration testing, spectrum analysis, and modal analysis.

[0071] The particle damper 12 is arranged at the position with the largest amplitude of the compressor 11, which can effectively control the vibration reduction for the vibration source, thereby improving the vibration reduction effect.

[0072] The shape of the particle damper 12 can be determined according to the installation position and the vibration reduction requirements.

[0073] In some embodiments, please refer to Figure 4 , the compressor 11 has a top end 1121 in its height direction Z, the outer surface of the top end 1121 is a planar structure, the particle damper 12 is arranged on the top end 1121 of the compressor 11, and the outer shape of the particle damper 12 is consistent with the shape of the top end 1121.

[0074] In some embodiments, please refer to Figure 6 , one end of the compressor 11 in its length direction X has an end cover 113, a fixing member 114 for connecting the mounting bracket 500 is arranged on the outer surface of the end cover 113, the particle damper 12 is arranged on the end cover 113 of the compressor 11, and the size of the particle damper 12 is smaller than that of the end cover 113 to avoid the fixing member 114. It can be understood that the end cover 113 is a part of the housing 111.

[0075] In some embodiments, please refer to Figure 4 , the compressor assembly 10 further includes a fastener 13 for fixing the box body 121 to the housing 111.

[0076] The fastener 13 is connected to the box body 121 and the housing 111. The fastener 13 includes but is not limited to bolts and screws.

[0077] With the above design, the fastener 13 can provide a stable and reliable mechanical connection. During the operation of the compressor 11, the particle damper 12 is not easily loosened, so the reliability of the compressor assembly 10 is high.

[0078] It can be understood that in some other embodiments, a locking structure such as a buckle can be used to fix the particle damper 12 to the housing 111 of the compressor 11, or the particle damper 12 can be pasted on the housing 111 of the compressor 11 through an adhesive, or the particle damper 12 can be installed on the housing 111 of the compressor 11 by using a fixture or a hoop.

[0079] In some embodiments, please refer to Figure 4 , the box body 121 includes a first side wall 1211 and a second side wall 1212 arranged opposite to each other, and there is an installation channel 124 for installing the fastener 13 and passing through the cavity 122 between the first side wall 1211 and the second side wall 1212.

[0080] The first side wall 1211 and the second side wall 1212 of the box body 121 are opposite and spaced apart, and a peripheral side wall 1213 is connected between them. The first side wall 1211, the second side wall 1212 and the peripheral side wall 1213 form a cavity 122 for accommodating damping particles 123. One of the first side wall 1211 and the second side wall 1212 is attached to the housing 111 of the compressor 11.

[0081] The installation channel 124 passes through the cavity 122 inside the box body 121 and penetrates through the first side wall 1211 and the second side wall 1212. Please refer to Figure 6 , a groove 125 can be provided at the port of the installation channel 124, and the groove 125 is used to abut against the head 132 of the fastening member 13; alternatively, threads for connecting the fastening member 13 can be provided on the inner wall of the installation channel 124.

[0082] The installation position and number of the installation channels 124 are determined according to application requirements. For example, in a specific embodiment, one installation channel 124 is provided on the box body 121, and the installation channel 124 is located in the middle of the box body 121.

[0083] The damping particles 123 are freely filled in the cavity 122. Between the first side wall 1211 and the second side wall 1212, multiple damping particles 123 are scattered in one layer or stacked in multiple layers.

[0084] With the above design, on the one hand, the installation channel 124 can provide an accurate installation position, reducing the assembly difficulty between the compressor 11 and the particle damper 12; on the other hand, after the fastening member 13 is directly inserted into the installation channel 124, the contact with the inner wall of the installation channel 124 is good, and the installation channel 124 can better disperse the pressure transmitted by the fastening member 13, reducing the risk of damage to the box body 121.

[0085] It can be understood that in some embodiments, the first side wall 1211 and the second side wall 1212 can also be curved walls, and the two can be buckled to enclose a sealed cavity 122. In addition, in some other embodiments, a connecting seat can also be provided on the box body 121, and through holes for installing the fastening member 13 can be provided on the connecting seat.

[0086] In some embodiments, please refer to Figure 4 , an installation channel 124 is provided on the box body 121, and an installation hole 115 is provided on the side wall of the housing 111. The installation hole 115 is opposite to the installation channel 124, and the installation hole 115 is used to install the fastening member 13.

[0087] The installation hole 115 is a through hole penetrating the side wall of the housing 111, and the fastening member 13 is sequentially inserted through the installation channel 124 and the installation hole 115.

[0088] With the above design, the structure of the housing 111 can be simplified. The fastener 13 passes through the installation channel 124 and is connected to the installation hole 115, and the assembly difficulty is relatively low.

[0089] In some embodiments, please refer to Figure 6 , an installation channel 124 is provided on the box body 121, and an installation post 116 protrudes from the outer wall of the housing 111. The installation post 116 is inserted into the installation channel 124, and an installation hole 115 for installing the fastener 13 is provided in the installation post 116.

[0090] The structure of the installation post 116 is adapted to the installation channel 124. For example, the cross-section of the installation channel 124 can be circular, the installation post 116 can be cylindrical, and the outer diameter of the installation post 116 is equal to or slightly smaller than the inner diameter of the installation channel 124; or, the cross-section of the installation channel 124 can be square, the installation post 116 is a square post, and the side length of the installation post 116 is equal to or slightly smaller than the side length of the installation channel 124.

[0091] The extending direction of the installation hole 115 in the installation post 116 is the same as the extending direction of the installation post 116. The installation hole 115 is a blind hole or a through hole that penetrates the installation post 116 and the housing 111.

[0092] The fastener 13 includes a connecting portion 131 and a head portion 132. The connecting portion 131 is inserted into the installation hole 115, and the head portion 132 abuts against the side wall of the box body 121 at one end of the installation channel 124. Alternatively, in some cases, a groove 125 is provided at one end of the installation channel 124, and the head portion 132 of the fastener 13 is assembled in the groove 125.

[0093] With the above design, the installation post 116 is inserted into the installation channel 124, which can improve the connection stability between the housing 111 of the compressor 11 and the box body 121 of the particle damper 12. Under the limiting effect of the installation post 116, the relative displacement between the compressor 11 and the particle damper 12 during vibration can be reduced, thereby ensuring the vibration reduction effect of the particle damper 12.

[0094] In the embodiments provided by the present application, the box body 121 has one or more cavities 122.

[0095] In some embodiments, please refer to Figure 5 , the box body 121 has a cavity 122.

[0096] The box body 121 is designed as a single-chamber structure, and the hollow space inside forms an integral cavity 122. The size and shape of the cavity 122 are determined according to application requirements.

[0097] With the above design, the damping particles 123 have a higher degree of freedom in the cavity 122. When the particle damper 12 receives vibration, the damping particles 123 can respond in a timely manner, and the collisions and frictions between the damping particles 123 are stronger, which is conducive to the rapid dissipation of vibration energy.

[0098] In some other embodiments, a plurality of independent cavities 122 may be provided in the box body 121, and different proportions of damping particles 123 or no damping particles 123 may be provided in each cavity 122 as needed.

[0099] It can be understood that by adjusting the filling ratio of the damping particles 123 in different cavities 122, a particle damper 12 with good damping effects on a variety of vibration frequencies can be designed.

[0100] With the above design, it is beneficial to improve the versatility of the particle damper 123.

[0101] In some embodiments, the filling rate of the damping particles 123 in the cavity 122 is 50%-90%.

[0102] Optionally, in a specific embodiment, the filling rate of the damping particles 123 in the cavity 122 is 70%.

[0103] The filling rate refers to the proportion of the damping particles 123 occupying the volume of the cavity 122.

[0104] The above filling rate range of the damping particles 123 is reasonable. The damping particles 123 can move freely in the cavity 122, and there are more collision opportunities between the damping particles 123 and between the damping particles 123 and the cavity wall of the cavity 122, so as to have good damping performance.

[0105] In some embodiments, the damping particles 123 are spherical particles, and the diameter of the damping particles 123 is 0.1 mm - 10 mm.

[0106] Exemplarily, the diameter of the damping particles 123 can be 0.1 mm, 2 mm, 5 mm, 8 mm, 10 mm.

[0107] On the one hand, the internal space of the cavity 122 is limited. The damping particles 123 are designed as a spherical structure, which is more likely to move or roll in the cavity 122, and it is not easy to get stuck during the movement or rolling of the damping particles 123. On the other hand, the size of the damping particles 123 is reasonable, which can ensure the contact area and collision effect between the damping particles 123 and between the damping particles 123 and the cavity wall.

[0108] In some embodiments, the mass of the particle damper 12 is 2%-5% of the mass of the compressor 11.

[0109] Optionally, in a specific embodiment, the mass of the particle damper 12 is 3% of the mass of the compressor 11.

[0110] The mass of the particle damper 12 and the mass of the compressor 11 are their respective overall masses.

[0111] The relative mass of the particle damper 12 and the compressor 11 affects the vibration reduction effect of the particle damper 12 and also affects the overall stability of the compressor assembly 10. The above-mentioned mass range of the particle damper 12 is set reasonably, the particle damper 12 can effectively suppress the vibration of the compressor 11, and the overall stability of the compressor assembly 10 is relatively high.

[0112] In some embodiments, the damping particles 123 are metal particles.

[0113] A plurality of damping particles 123 are arranged in the cavity 122 of the box body 121, and the plurality of damping particles 123 can be made of the same or different metal materials. To ensure that the plurality of damping particles 123 can move independently, the damping particles 123 are non-magnetic metal particles.

[0114] On the one hand, metal particles have good wear resistance, can withstand large vibrations and have good vibration reduction effects; on the other hand, during the vibration process, the collision and friction of the damping particles 123 can convert the vibration energy into heat energy, and metal particles have good heat conduction ability and can quickly dissipate the heat.

[0115] It can be understood that in some other embodiments, the damping particles 123 can also be ceramic particles, plastic particles, rubber particles, but not limited thereto.

[0116] In some embodiments, the damping particles 123 are any one of lead particles, iron particles, aluminum particles, and tungsten carbide particles.

[0117] Optionally, in a specific embodiment, the damping particles 123 are tungsten carbide particles.

[0118] The above types of damping particles 123 have high stability and strong adaptability and can be used in a variety of environments.

The damping particles 123 are spherical metal particles, the diameter of the damping particles 123 is 0.1 mm - 10 mm, and the filling rate of the damping particles 123 in the cavity 122 is 50% - 90%. The box body 121 of the particle damper 12 includes a first side wall 1211 and a second side wall 1212 arranged opposite to each other. There is an installation channel 124 between the first side wall 1211 and the second side wall 1212. The fastener 13 sequentially passes through the installation channel 124 of the box body 121 and the installation hole 115 of the housing 111 to fix the particle damper 12 to the outer wall of the housing 111 of the compressor 11. The mass of the particle damper 12 is 2% - 5% of the mass of the compressor 11. In the above embodiment, by arranging the particle damper 12 on the outer wall of the housing 111 of the compressor 11, and using the movement of the damping particles 123 in the particle damper 12 to convert part of the vibration energy of the compressor 11 into heat energy, the vibration energy of the compressor 11 can be dissipated, the amplitude of the compressor 11 can be reduced, so as to achieve vibration reduction of the compressor 11, and by suppressing the vibration of the compressor 11, the noise problem caused by vibration can also be improved.
