Description

Technical Field

[0001] The present invention relates to the technical field of vibration reduction devices, and in particular to a vibration reduction structure and refrigeration equipment. Background Art

[0002] At present, the refrigeration method adopted by major air-conditioning brands on the market is compression refrigeration, which is the most common refrigeration method. Refrigeration is achieved through four processes: compression, condensation, expansion, and evaporation. The key equipment of compression refrigeration is the compressor, which increases the temperature and pressure by compressing the refrigerant gas, and then releases heat in the condenser. The refrigerant becomes liquid, and then reduces the pressure and temperature through the expansion valve, absorbing heat in the evaporator to achieve the cooling effect.

[0003] Therefore, as one of the core components of refrigeration, the compressor plays an important role. However, since the compressor will vibrate during operation, it will not only reduce the user's comfort, but also transmit its vibration to the entire pipeline system through the pipes connected to it. At this time, the stress of the pipeline system may exceed the standard. If the fixed frequency of the pipeline is just near the compressor frequency, it will cause the pipeline system to resonate. If it is not handled, the pipeline will suffer from fatigue fracture in advance due to excessive stress after the unit has been running for a period of time, which is not conducive to the stability and safety of the unit.

[0004] Therefore, how to provide a vibration reduction structure that can reduce the vibration of the compressor is an urgent problem to be solved. Summary of the invention

[0042] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention is further described in detail below in conjunction with the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. Thus, a feature indicated in this specification will be used to illustrate one of the features of an embodiment of the present invention, rather than implying that each embodiment of the present invention must have the described features. In addition, it should be noted that this specification describes many features. Although certain features can be combined together to illustrate possible system designs, these features can also be used in other combinations that are not explicitly described. Thus, unless otherwise stated, the described combinations are not intended to be limiting.

[0043] The principle and structure of the present invention are described in detail below with reference to the accompanying drawings and embodiments.

[0044] Example 1

[0045] See attached Figure 1-2 , the present invention proposes a vibration reduction structure, including a vibration reduction cylinder 10 and a vibration device 20 located in the vibration reduction cylinder 10;

[0046] A plurality of vibration-damping spacers 101 are provided between the vibration-damping cylinder 10 and the vibration device 20 . The vibration-damping spacers 101 separate the area between the vibration-damping cylinder 10 and the vibration device 20 to form a plurality of vibration-damping spaces 102 . Liquid vibration-damping medium is provided in the vibration-damping spaces 102 .

[0047] It should be noted that the vibration device 20 in this embodiment is illustrated by a compressor, and the compressor is connected to other devices through a pipeline system; the liquid vibration damping medium in this embodiment is illustrated by water.

[0048] In this way, when the vibration device 20 starts to run, it will inevitably generate vibration. At this time, the vibration-damping space 102 and the liquid vibration-damping medium therein can be regarded as a mass-spring system (the inner wall of the vibration-damping space 102 and the interface of the liquid vibration-damping medium can be regarded as a spring, and the liquid vibration-damping medium in the vibration-damping space 102 can be regarded as a mass). Then, the vibration generated by the vibration device 20 will cause the liquid vibration-damping medium to start vibrating accordingly, and the liquid vibration-damping medium will generate a force toward the inner wall of the corresponding vibration-damping space 102. According to Newton's third law of motion, the inner wall of the corresponding vibration-damping space 102 will generate a reverse force toward the liquid vibration-damping medium, which is equivalent to the inner wall of the corresponding vibration-damping space 102 generating reverse vibrations, forming vibrations of the mass-spring system, and then dissipating the vibrations generated by the vibration device 20; and because the liquid vibration-damping medium itself also has good damping characteristics, when the vibration device 20 vibrates, the liquid vibration-damping medium will form tiny vortices in the corresponding vibration-damping space 102, thereby dissipating the vibration energy, thereby further dissipating the vibrations generated by the vibration device 20.

[0049] Therefore, the present invention dissipates the vibration generated by the vibration device 20 located in the vibration damping space 102 through a mass-spring system composed of the vibration damping space 102 and the liquid vibration damping medium therein, thereby reducing the noise of the vibration device 20 and improving the user's comfort; and can also make the vibration frequency of the vibration device 20 away from the fixed frequency of the pipeline system connected to the vibration device 20, effectively avoiding the resonance phenomenon of the pipeline system, preventing the vibration displacement and stress of the pipeline system from exceeding the standard, causing pipeline fatigue fracture, and thereby improving the stability and safety of the unit equipped with the vibration device 20.

[0050] It should be noted that Newton's third law of motion is: the action and reaction forces between two interacting objects are always equal in magnitude, opposite in direction, and act on the same straight line.

[0051] The damping space 102 and the liquid damping medium therein can be regarded as the principle of a mass-spring system:

[0052] 1. Elastic properties: When the liquid damping medium in the damping space 102 is subjected to external pressure or vibration, the liquid damping medium will be displaced and deformed like a spring. This deformation is not permanent, but has a certain recovery ability. For example, when the damping space 102 is impacted, the liquid damping medium will produce fluctuations, which will propagate in the damping space 102 and gradually decay, similar to the vibration of a spring.

[0053] 2. Energy storage and release: Springs can store and release mechanical energy. Similarly, liquid damping medium can also store and release energy in the damping space 102. When the damping space 102 is acted upon by an external force, the liquid damping medium will store a portion of energy, and then release this energy after the external force disappears, causing the liquid damping medium to fluctuate.

[0054] 3. Damping effect: The spring will have a damping effect during the vibration process, that is, the vibration amplitude will gradually decrease. Similarly, the fluctuation of the liquid damping medium in the corresponding damping space 102 will also gradually decay due to the viscosity of the liquid damping medium and the friction of the inner wall of the damping space 102, and finally reach a stable state.

[0055] In summary, comparing the liquid damping medium in the damping space 102 to a spring is to more intuitively understand the dynamic behavior and energy transfer characteristics of the liquid damping medium under specific conditions.

[0056] In order to improve the vibration reduction effect of the vibration reduction structure, all the vibration reduction spaces 102 are evenly arranged in the vibration reduction cylinder 10 .

[0057] It should be noted that, in this embodiment, four vibration reduction spaces 102 are evenly arranged between the inner wall of the vibration reduction cylinder 10 and the vibration device 20, and the four vibration reduction spaces 102 are respectively the first vibration reduction space, the second vibration reduction space, the third vibration reduction space and the fourth vibration reduction space; wherein, the first vibration reduction space and the third vibration reduction space are arranged oppositely, and the second vibration reduction space and the fourth vibration reduction space are arranged oppositely. Of course, the vibration reduction space 102 can also be set to two, three, five or more according to actual conditions, which is not limited here.

[0058] In this way, four evenly arranged vibration-damping spaces 102 are provided between the inner wall of the vibration-damping cylinder 10 and the vibration device 20, which can better adjust the vibration-damping effect of each vibration-damping space 102 and prevent the vibration-damping space 102 from being too small and unable to effectively dissipate the vibration generated by the vibration device 20.

[0059] In order to further improve the vibration reduction effect of the vibration reduction structure, refer to the attached Figure 3 , the vibration reduction structure further includes a water storage tank 40;

[0060] A vibration sensor 50 is provided in each of the vibration reduction spaces 102, and the vibration sensor 50 is used to detect the vibration transmission direction of the vibration device 20;

[0061] Each of the vibration damping spaces 102 is connected to the water tank 40 through a first pipe 401 , and a water inlet solenoid valve 402 is provided on one side of the first pipe 401 corresponding to each of the vibration damping spaces 102 , and a water pump 403 is provided on the other side of the first pipe 401 close to the water tank 40 .

[0062] It should be noted that the vibration reduction structure proposed in this embodiment also includes a control unit (not shown, the same throughout), which is electrically connected to the vibration device 20, all vibration sensors 50 and all water inlet solenoid valves 402 respectively.

[0063] In this way, the present embodiment can detect the vibration transmission direction of the vibration device 20 through the vibration sensor 50. For example, when the control unit detects through the vibration sensor 50 that the vibration transmission direction of the vibration device 20 is mainly concentrated in a certain vibration reduction space 102, the control unit will open the water inlet solenoid valve 402 corresponding to the vibration reduction space 102 and start the water pump 403, so that the liquid vibration reduction medium in the water storage tank 40 is pumped to the vibration reduction space 102 through the water pump 403, thereby increasing the weight of the liquid vibration reduction medium in the vibration reduction space 102, thereby improving the vibration reduction effect of the mass-spring system composed of the vibration reduction space 102, and then dissipating the vibration transmitted to the vibration reduction space 102. Similarly, the vibration transmitted to the remaining vibration reduction spaces 102 is also processed in the same way.

[0064] It should be noted that the first pipeline 401 is divided into four first branches corresponding to the four vibration reduction spaces 102, and each first branch is provided with a water inlet solenoid valve 402. Each vibration reduction space 102 can be provided with a water pump 403, or all vibration reduction spaces 102 share a water pump 403, which is not limited here.

[0065] Among them, refer to the attached Figure 3 , the water storage tank 40 is located at the bottom of the vibration damping cylinder 10;

[0066] Each of the vibration-damping spaces 102 is connected to the water storage tank 40 through a second pipe 404 , and a water outlet solenoid valve 405 is provided on one side of the second pipe 404 corresponding to each of the vibration-damping spaces 102 .

[0067] It should be noted that the control unit is electrically connected to all the water outlet solenoid valves 405. The second pipeline 404 is divided into four second branches corresponding to the four vibration reduction spaces 102, and each second branch is provided with a water outlet solenoid valve 405.

[0068] In this way, the control unit can determine whether the vibration frequency and / or amplitude data of the corresponding vibration damping space 102 is normal through the vibration sensor 50, and then monitor whether the entire vibration damping cylinder 10 is in a normal state; for example, when the vibration frequency and / or amplitude of at least one vibration damping space 102 is abnormal, the control unit will first control the vibration device 20 to stop working, and then open the water outlet solenoid valve 405 corresponding to the vibration damping space 102, so that the liquid vibration damping medium in the vibration damping space 102 is recovered into the water tank 40, and then the vibration damping structure is inspected and repaired.

[0069] It should be noted that, usually, the vibration frequency and amplitude of an object will have a normal range of values ​​depending on its size, installation environment, structural shape and other factors. Outside this range, it can be understood that there is an abnormality. For ease of understanding, in this embodiment, the vibration-damping cylinder 10 and the vibration-damping spacer 101 are both made of stainless steel. At this time, the vibration frequency of the vibration-damping space 102 and the liquid vibration-damping medium therein is usually between 0.1Hz and 100Hz, and the amplitude is usually between 0.01mm and 0.1mm. If the values ​​of the vibration frequency and amplitude are not within this range, it can be preliminarily determined that the vibration-damping cylinder 10 is abnormal and needs to be repaired.

[0070] Of course, if it is found that there is too much liquid damping medium in the damping space 102 during the operation of the vibration device 20, there is no need to stop the vibration device 20. Instead, the control unit can directly open the corresponding water outlet solenoid valve 405 to reduce the liquid damping medium in the corresponding damping space 102.

[0071] It should be noted that when the vibration of the vibration device 20 is transmitted to the vibration-damping spacer 101, since the thickness of the vibration-damping spacer 101 is not too thick, the vibration energy is transmitted to the liquid vibration-damping medium in the two vibration-damping spaces 102 adjacent to the vibration-damping spacer 101, thereby dissipating the vibration.

[0072] Of course, in other embodiments, refer to the attached Figure 4 The water tank 40 does not have to be located at the bottom of the vibration damping cylinder 10. In this case, the water tank 40 needs to be additionally provided with a water inlet pump 408 to pump the liquid vibration damping medium in the corresponding vibration damping cylinder 10 back into the water tank 40.

[0073] In order to prevent the temperature of the liquid damping medium in the water tank 40 from being too low or even freezing, thereby affecting the damping effect of the damping structure, refer to the attached Figure 3 A second heating structure 60 is provided at the bottom of the water tank 40 .

[0074] It should be noted that the water storage tank 40 proposed in this embodiment is equipped with a second temperature sensor 409 , and the control unit is electrically connected to the second heating structure 60 and the second temperature sensor 409 , respectively.

[0075] In this way, when the control unit detects through the second temperature sensor 409 that the temperature of the liquid damping medium in the water tank 40 is lower than the first preset temperature, the second heating structure 60 is started to prevent the liquid damping medium from freezing; and when the control unit detects through the second temperature sensor 409 that the temperature of the liquid damping medium in the water tank 40 reaches the second preset temperature, the second heating structure 60 is turned off.

[0076] It should be noted that the first preset temperature proposed in this embodiment is preferably 0°C, and the second preset temperature proposed in this embodiment is preferably 20°C.

[0077] In order to prevent the temperature of the liquid damping medium in the damping space 102 from being too low or even freezing, thereby affecting the damping effect of the damping structure, refer to the attached Figure 3 The vibration-damping cylinder 10 is provided with a first heating structure 30 corresponding to all the vibration-damping spaces 102 .

[0078] The vibration reduction space 102 proposed in this embodiment is equipped with a first temperature sensor 103 , and the control unit is electrically connected to the first heating structure 30 and the first temperature sensor 103 , respectively.

[0079] In this way, when the control unit detects through the first temperature sensor 103 that the temperature of the liquid vibration damping medium in the corresponding vibration damping space 102 is lower than the third preset temperature, the first heating structure 30 is started to prevent the liquid vibration damping medium from freezing; and when the control unit detects through the first temperature sensor 103 that the temperature of the liquid vibration damping medium in the corresponding vibration damping space 102 reaches the fourth preset temperature, the first heating structure 30 is turned off.

[0080] Among them, the third preset temperature proposed in this embodiment is preferably 10°C, and the fourth preset temperature proposed in this embodiment is preferably 38°C.

[0081] A water level sensor 410 is also provided in the water tank 40, and the water level sensor 410 is electrically connected to the control unit. The water level sensor 410 is used to monitor the liquid level in the water tank 40 and provide real-time data to monitor water level changes.

[0082] Example 2

[0083] Based on the same inventive concept, refer to the attached Figure 5 The present invention also proposes a refrigeration device, which includes the vibration reduction structure described above.

[0084] It should be noted that the refrigeration device in this embodiment is illustrated by an air conditioner. Correspondingly, the vibration device 20 located in the vibration-damping cylinder 10 is preferably a compressor of the air conditioner.

[0085] In this way, when the refrigeration equipment starts to run, the corresponding startup of the compressor will inevitably generate vibration. At this time, the vibration-damping space 102 and the liquid vibration-damping medium therein can be regarded as a mass-spring system (the inner wall of the vibration-damping space 102 and the interface of the liquid vibration-damping medium can be regarded as a spring, and the liquid vibration-damping medium in the vibration-damping space 102 can be regarded as a mass). Then, the vibration generated by the compressor will cause the liquid vibration-damping medium to start vibrating accordingly, and the liquid vibration-damping medium will generate a force toward the inner wall of the corresponding vibration-damping space 102. According to Newton's third law of motion, the inner wall of the corresponding vibration-damping space 102 will generate a reverse force toward the liquid vibration-damping medium, which is equivalent to the inner wall of the corresponding vibration-damping space 102 generating reverse vibrations, forming vibrations of the mass-spring system, and then dissipating the vibrations generated by the compressor; and because the liquid vibration-damping medium itself also has good damping characteristics, when the compressor vibrates, the liquid vibration-damping medium will form a tiny vortex in the corresponding vibration-damping space 102, thereby consuming vibration energy, thereby further dissipating the vibrations generated by the compressor.

[0086] Therefore, the present invention dissipates the vibration generated by the compressor in the vibration damping space 102 through a mass-spring system composed of the vibration damping space 102 and the liquid vibration damping medium therein, thereby reducing the noise of the vibration device 20 and improving the user's comfort; and can also make the vibration frequency of the compressor away from the fixed frequency of the pipeline system connected to the compressor, effectively avoiding the resonance phenomenon of the pipeline system, preventing the vibration displacement and stress of the pipeline system from exceeding the standard, causing pipeline fatigue fracture, and thus improving the stability and safety of the refrigeration equipment.

[0087] Among them, refer to the attached Figure 5 , the refrigeration equipment further includes a condenser 70 and a spray device 80 arranged corresponding to the condenser 70;

[0088] The spray device 80 is connected to the water pump 403 via a third pipe 801 .

[0089] It should be noted that the refrigeration device also includes an evaporator 100, and the pipeline system sequentially connects the compressor, the condenser 70 and the evaporator 100 in a circular manner, and an expansion valve 110 is also provided on the pipeline between the condenser 70 and the evaporator 100. In this way, when the refrigeration device is cooling, the refrigerant will come out of the compressor, pass through the condenser 70, and then enter the evaporator 100 after throttling through the expansion valve 110, and finally return to the compressor.

[0090] It should be noted that the liquid vibration damping medium proposed in this embodiment is preferably water or other liquids that are easy to spray by the spray device 80, do not affect the use effect of the condenser 70, and have good damping properties.

[0091] In this way, the control unit starts the water pump 403 , and the liquid damping medium in the water storage tank 40 is sprayed on the condenser 70 through the spray device 80 by the water pump 403 , thereby improving the heat exchange efficiency of the condenser 70 .

[0092] In this embodiment, the spray device 80 is disposed above the condenser 70 .

[0093] In order to improve the reuse rate of liquid damping medium, refer to the attached Figure 5 A matching water receiving tray 90 is provided at the bottom of the condenser 70 , and the water receiving tray 90 is communicated with the water storage tank 40 through a fourth pipe 406 .

[0094] Of course, at this time, the water storage tank 40 is located below the water receiving tray 90 so that the water in the water receiving tray 90 can flow back into the water storage tank 40 .

[0095] Among them, refer to the attached Figure 5 The fourth pipe 406 is provided with a filter device 407. The filter device 407 is used to filter the water flowing from the water receiving tray 90 to the water storage tank 40, and has the following functions:

[0096] 1. When used for filtering spray heat exchange, water may carry impurities such as dust in the air, dirt on the surface of the equipment, and corrosion products in the system, preventing the water from affecting the operation of the entire refrigeration equipment during circulation.

[0097] 2. Minerals dissolved in water (such as calcium and magnesium ions) tend to form scale after heating or evaporation, while certain organic matter and microbial metabolites may cause corrosion of metal parts. Filtration can reduce the amount of these substances, thereby slowing down the occurrence of scaling and corrosion and extending the service life of refrigeration equipment.

[0098] 3. For some sensitive equipment, such as pumps, valves and other precision instruments, even trace amounts of solid particles may have an adverse effect on their performance. Therefore, ensuring water cleanliness is one of the important measures to protect the stable operation of the entire refrigeration equipment.

[0099] Obviously, the embodiments described above are only some embodiments of the present invention, rather than all embodiments. The preferred embodiments of the present invention are given in the accompanying drawings, but they do not limit the patent scope of the present invention. The present invention can be implemented in many different forms. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive. Although the present invention has been described in detail with reference to the aforementioned embodiments, for those skilled in the art, it is still possible to modify the technical solutions recorded in the aforementioned specific implementation methods, or to replace some of the technical features therein with equivalents. Any equivalent structure made using the contents of the specification and drawings of the present invention, directly or indirectly used in other related technical fields, is also within the scope of patent protection of the present invention.
