Description

Technical Field

[0001] This application relates to the field of compressor technology, and more specifically, to a liquid separator. Background Technology

[0002] In modern refrigeration and air conditioning systems, the rotary compressor, as a core component, is crucial to the overall system performance due to its efficient and stable operation. The gas-liquid separator, especially its filter support structure, is a key component in preventing liquid refrigerant from entering the compressor cavity and avoiding "liquid slugging" damage. Traditionally designed filter supports are mostly solid structures made of a single material, whose main function is to fix the filter in the airflow channel, ensuring effective separation of liquid droplets from the refrigerant gas.

[0003] However, when the compressor is under high load, the high-speed airflow impacts the filter and support, which will cause strong vibrations and thus generate high-frequency noise. The frequency range is usually concentrated between 500Hz and 2kHz, which has a negative impact on the environment and also reduces the user's acceptance of the equipment. Utility Model Content

[0004] The main purpose of this invention is to provide a liquid separator to solve the problem of vibration and noise generated by the filter support under high-speed airflow impact in the prior art.

[0005] To achieve the above objectives, according to one aspect of the present invention, a liquid dispenser is provided, including a liquid dispenser housing having an inlet and a dispensing outlet.

[0006] The filter support is installed inside the separator housing to perform gas-liquid separation on the liquid to be separated that enters from the liquid inlet, so as to form liquid and gas.

[0007] The vibration-absorbing structure is located on the side of the filter support away from the separator housing and in contact with the separator housing to absorb the vibration energy generated when gas passes through the filter support, thereby reducing the vibration amplitude of the filter support.

[0008] Furthermore, the vibration-absorbing structure includes a vibration-absorbing chamber;

[0009] At least one first partition is disposed within the vibration-absorbing chamber to divide the vibration-absorbing chamber into multiple sub-chambers;

[0010] Multiple sub-chambers are arranged sequentially along the gas flow direction. Each sub-chamber is used to contain vibration-absorbing particles, which absorb the vibration energy generated when the gas passes through the filter support.

[0011] Furthermore, the vibration-absorbing structure also includes at least one second partition, which is disposed in the sub-chamber to divide the sub-chamber into multiple sub-chambers. The multiple sub-chambers are distributed around the axis of the distributor housing, and the vibration-absorbing particles are located in each sub-chamber.

[0012] Furthermore, the vibration-absorbing structure also includes a first support component, which is disposed on the side of the filter support away from the dispenser housing;

[0013] The second support component is disposed on the side of the first support component away from the filter support;

[0014] The first support component and the second support component together form a vibration-absorbing chamber.

[0015] Furthermore, the first support component and the second support component are connected by a heat fitting process.

[0016] Furthermore, the vibration-absorbing particles are made of at least one of polymer particles and metal microspheres; and / or, the filling density of the vibration-absorbing particles is 30% to 70%.

[0017] Furthermore, when the vibration-absorbing particles are made of polymer particles, the damping ratio of the vibration-absorbing particles is greater than or equal to 0.3; and / or, the vibration-absorbing particles are made of at least one of polyurethane elastic microspheres, silicone particles, or rubber particles.

[0018] Furthermore, when the material of the vibration-absorbing particles is metal microspheres, the particle size of the vibration-absorbing particles is between 0.5 mm and 2 mm; and / or, the material of the vibration-absorbing particles is at least one of stainless steel or titanium alloy microspheres.

[0019] Furthermore, the dispenser also includes a vibration damping component, which is disposed between the filter support and the dispenser housing to absorb the vibration energy generated when the gas passes through the filter support.

[0020] Furthermore, the thickness of the vibration damping component is 1mm to 2mm; and / or, the hardness of the vibration damping component is in the range of 30-70 Shore A.

[0021] By applying the technical solution of this utility model, the vibration-absorbing structure is set on the side of the filter support away from the separator housing and directly contacts the housing, forming a direct and effective vibration energy absorption barrier. This design makes full use of the damping performance of the vibration-absorbing structure, which can quickly absorb and convert vibration energy when the airflow impacts the filter support, significantly reducing the vibration amplitude of the support, reducing the high-frequency noise caused by it, and optimizing the working environment of the compressor.

[0022] By tightly integrating the vibration-absorbing structure with the outer side of the filter support, not only is the timeliness and effectiveness of vibration suppression improved, but the connection stability between the filter support and the housing is also indirectly enhanced. This close-contact design ensures that the filter support remains stable even under complex operating conditions and severe airflow fluctuations, reducing hard contact between the filter assembly and the housing caused by vibration, avoiding secondary entrainment of droplets, thereby improving the accuracy of gas-liquid separation, protecting the compressor from liquid slugging damage, and maintaining the safe operation of the equipment.

[0023] In addition, the synergistic effect of the vibration-absorbing structure and the filter support reduces structural fatigue damage to the filter support, extends the service life of the equipment, and reduces maintenance costs. Attached Figure Description

[0030] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0031] In modern refrigeration and air conditioning systems, the rotary compressor, as a core component, is crucial to the overall system performance due to its efficient and stable operation. The gas-liquid separator, especially its filter support structure, is a key component in preventing liquid refrigerant from entering the compressor cavity and avoiding "liquid slugging" damage. Traditionally designed filter supports are mostly solid structures made of a single material, whose main function is to fix the filter in the airflow channel, ensuring effective separation of liquid droplets from the refrigerant gas.

[0032] However, when the compressor is under high load, the high-speed airflow impacts the filter and support, which will cause strong vibrations and thus generate high-frequency noise. The frequency range is usually concentrated between 500Hz and 2kHz, which has a negative impact on the environment and also reduces the user's acceptance of the equipment.

[0033] The main purpose of this invention is to provide a liquid separator to solve the problem of vibration and noise generated by the filter support under high-speed airflow impact in the prior art.

[0034] like Figures 1 to 3 As shown, the liquid dispenser provided in this application includes a liquid dispenser housing 1, which has a liquid inlet and a liquid dispensing outlet.

[0035] Filter support 2 is installed inside the separator housing 1 to perform gas-liquid separation on the liquid to be separated that enters from the liquid inlet, so as to form liquid and gas.

[0036] The vibration-absorbing structure 3 is disposed on the side of the filter support 2 away from the separator housing 1 and in contact with the separator housing 1 to absorb the vibration energy generated when the gas passes through the filter support 2, thereby reducing the vibration amplitude of the filter support 2.

[0037] In the use of the separator provided by this utility model, the refrigerant containing a gas-liquid mixture first enters through the liquid inlet of the separator housing 1. The channels inside the separator housing 1 guide the refrigerant to the location of the filter support 2. The filter support 2 is disposed inside the separator housing 1, and its structural design enables it to effectively intercept liquid droplets, achieving gas-liquid separation, thereby forming pure gas and collected liquid. In particular, a vibration-absorbing structure 3 is integrated on the side of the filter support 2 away from the separator housing 1. This vibration-absorbing structure 3 can respond instantly and absorb the vibration energy generated when the refrigerant gas passes through the filter at high speed.

[0038] By employing this unique vibration-absorbing structure 3 design, the gas-liquid separator of this invention significantly improves its vibration control capability under high-speed airflow impact. Specifically, the vibration amplitude of the filter support 2 is effectively reduced, and the resulting high-frequency noise (mainly in the 500Hz-2kHz range) is also significantly reduced. This directly improves the smoothness of compressor operation, reduces noise pollution, and enhances the user experience.

[0039] Furthermore, the vibration-absorbing structure 3 includes a vibration-absorbing chamber 31;

[0040] At least one first partition 32 is disposed within the vibration-absorbing chamber 31 to divide the vibration-absorbing chamber 31 into multiple sub-chambers;

[0041] Multiple sub-chambers are arranged sequentially along the gas flow direction. Each sub-chamber is used to contain vibration-absorbing particles 33, so as to absorb the vibration energy generated when the gas passes through the filter support 2.

[0042] When high-pressure gas passes rapidly through the filter support 2, strong vibrations are inevitable. However, in this invention, these vibrational energies are effectively captured and converted by the vibration-absorbing structure 3. Vibration-absorbing particles 33 are filled in each sub-chamber. The pulsation and impact of the gas cause the vibration-absorbing particles 33 to collide with each other within the sub-chambers. Through friction and energy conversion, the vibrational energy is transformed into heat energy or other forms of energy, thus achieving efficient vibration suppression. This process reduces the dynamic displacement of the filter support 2 and lowers the noise level. This multi-stage, multi-chamber vibration-absorbing design, compared to a single-chamber structure, can more effectively absorb vibrations of different frequencies and intensities, ensuring that the filter support 2 maintains its optimal working condition under various operating conditions. This avoids structural damage and functional degradation caused by vibration, thereby improving the overall performance and reliability of the compressor gas-liquid separator.

[0043] Furthermore, the vibration-absorbing structure 3 also includes at least one second partition 34, which is disposed in the sub-chamber to divide the sub-chamber into multiple sub-chambers 35. The multiple sub-chambers 35 are distributed around the axis of the distributor housing 1, and the vibration-absorbing particles 33 are located in each sub-chamber 35.

[0044] By introducing a second separator 34 into the vibration-absorbing structure 3, this application further enhances the vibration suppression performance of the filter support 2. At least one second separator 34 forms a smaller sub-chamber 35 within the sub-chamber. This multi-stage separation vibration-absorbing design makes the vibration-absorbing particles 33 more evenly and densely distributed, enabling a faster and more effective response to vibrations caused by gas flow. The multiple sub-chambers and sub-chambers 35 are symmetrically distributed around the axis of the distributor housing 1, ensuring that the impact force of gas entering from all directions is absorbed to the same degree. This not only minimizes the overall vibration amplitude of the filter support 2 but also effectively reduces high-frequency noise, improves the smoothness of compressor operation, and reduces noise pollution in the working environment. More importantly, this design significantly reduces fatigue damage to the support structure and extends the service life of the equipment by increasing the collision opportunities and energy dissipation paths between damping particles. Furthermore, the vibration-absorbing particles within each sub-chamber 35 can work independently, maintaining good vibration suppression even under extreme conditions, avoiding secondary entrainment of droplets, improving gas-liquid separation efficiency, and ensuring long-term stable operation and performance reliability of the compressor.

[0045] Furthermore, the vibration-absorbing structure 3 also includes a first support component 36, which is disposed on the side of the filter support 2 away from the dispenser housing 1;

[0046] The second support member 37 is disposed on the side of the first support member 36 away from the filter support 2;

[0047] The first support component 36 and the second support component 37 together form the vibration-absorbing chamber 31.

[0048] This application creates a stable frame structure by adding a first support component 36 and a second support component 37, which together construct the vibration-absorbing chamber 31. This design not only enhances the overall stability of the vibration-absorbing structure 3 but also provides a more precise energy absorption platform. When gas passes through the filter support 2 at high speed, the vibration-absorbing chamber 31 between the first support component 36 and the second support component 37 can respond immediately, rapidly absorbing and converting vibration energy through the vibration-absorbing particles 33 filling it. This process occurs repeatedly in sub-chambers and sub-chambers 35 at different levels and locations, ensuring omnidirectional dissipation of vibration energy and significantly reducing the vibration amplitude of the filter support 2 and the resulting noise, especially in the high-frequency range of 500Hz to 2kHz, where the effect is particularly noticeable.

[0049] Furthermore, the first support component 36 and the second support component 37 are connected by a heat fitting process.

[0050] This technical solution employs a heat-shrink technique in the connection process between the first support component 36 and the second support component 37. This process choice has a significant positive impact on improving the overall performance of the vibration-absorbing structure 3. The heat-shrink process expands the material through heating, followed by cooling and contraction, thereby achieving a tight connection between the two components. This connection method not only ensures a tight fit between the first support component 36 and the second support component 37, enhancing the sealing and structural stability of the vibration-absorbing chamber 31, but also reduces the risk of loosening or separation of components under high-pressure gas impact due to its robust connection characteristics, further improving the efficiency and reliability of vibration suppression.

[0051] Furthermore, the vibration-absorbing particles 33 are made of at least one of polymer particles and metal microspheres; and / or, the filling density of the vibration-absorbing particles 33 is 30% to 70%.

[0052] The selection of materials and optimization of the packing density of the vibration-absorbing particles 33 play a crucial role in improving the vibration control performance of the compressor gas-liquid separator filter support. Firstly, the vibration-absorbing particles 33 are selected from at least one of high-molecular polymer particles and metal microspheres. These materials not only have a high damping ratio, effectively absorbing vibration energy, but also possess good wear resistance and temperature resistance. High-molecular polymer particles, such as polyurethane elastic microspheres or silicone particles, can rapidly convert vibration energy into heat energy due to their high damping characteristics; metal microspheres, such as stainless steel or titanium alloy microspheres, due to their high density and robust physical properties, can quickly dissipate vibration energy during mutual collisions while maintaining structural integrity.

[0053] Secondly, the packing density of the vibration-absorbing particles 33 is set between 30% and 70%. This range is chosen to balance the collision efficiency between particles and the gas flow. A lower packing density (30%) allows sufficient space for free collisions between particles, improving the efficiency of energy conversion; while a higher packing density (70%) ensures that the particles can participate more densely in the energy dissipation process under airflow impact, while avoiding gas channel blockage caused by excessively high packing density, thus ensuring smooth flow of refrigerant gas and efficient gas-liquid separation.

[0054] Furthermore, when the vibration-absorbing particles 33 are made of polymer particles, the damping ratio of the vibration-absorbing particles 33 is greater than or equal to 0.3; and / or, the vibration-absorbing particles 33 are made of at least one of polyurethane elastic microspheres, silicone particles, or rubber particles.

[0055] In the technical solution, the material and damping ratio of the vibration-absorbing particles 33 were specially optimized to achieve more efficient and targeted vibration energy absorption. When the vibration-absorbing particles are made of polymer materials, especially those with high damping ratios (≥0.3), such as polyurethane elastic microspheres, silicone particles, or rubber particles, their inherent properties can significantly enhance energy conversion efficiency.

[0056] Furthermore, when the material of the vibration-absorbing particles 33 is metal microspheres, the particle size of the vibration-absorbing particles 33 is between 0.5 mm and 2 mm; and / or, the material of the vibration-absorbing particles 33 is at least one of stainless steel and titanium alloy microspheres.

[0057] In a further technical implementation of this technical solution, when the vibration-absorbing particles 33 are made of metal microspheres, the importance of their particle size range and material selection is particularly emphasized, aiming to optimize the absorption and conversion of vibration energy, while taking into account the structural integrity of the filter support and the gas flow efficiency.

[0058] When the particle size is set between 0.5mm and 2mm, it can not only ensure sufficient mass to absorb vibration energy, but also make the metal microspheres more evenly distributed in the sub-chamber and the dividing chamber 35 through precise size control, avoiding local stress concentration and partial blockage of gas channels caused by particle accumulation, thus ensuring smooth gas flow and gas-liquid separation efficiency.

[0059] Metal microspheres in this size range can react rapidly during vibration, and through high-speed collisions and deformations with each other, they can efficiently convert the vibration energy caused by airflow into heat energy and other non-mechanical forms of energy, which significantly reduces the overall vibration amplitude and high-frequency noise (500Hz to 2kHz) of the filter support.

[0060] Furthermore, the separator also includes a vibration damping component 4, which is disposed between the filter support 2 and the separator housing 1 to absorb the vibration energy generated when the gas passes through the filter support 2.

[0061] Optionally, the vibration damping component 4 is made of rubber.

[0062] When the refrigerant gas flows through the filter support 2, the resulting vibration energy is not only efficiently dissipated by the vibration-absorbing particles 33, but can also be further blocked and absorbed by the vibration damping components 4, ensuring multi-level and comprehensive suppression of vibration energy.

[0063] Vibration damping component 4, such as an elastic layer made of rubber, effectively buffers the vibration of the filter support under airflow impact due to its inherent high elastic modulus and damping characteristics. This significantly reduces the degree of vibration transmission to the distributor housing 1, thereby reducing the resonance phenomenon of the distributor housing 1, further reducing equipment operating noise, and optimizing the compressor's operating environment. The choice of rubber material also provides good temperature resistance and corrosion resistance, enabling it to maintain stable performance in the high-temperature and refrigerant environments of the compressor, extending the service life of the vibration damping component and reducing maintenance costs.

[0064] Furthermore, the thickness of the damping component 4 is 1mm to 2mm; and / or, the hardness of the damping component 4 is in the range of 30-70 Shore A.

[0065] In this technical solution, the precise thickness setting and optimized hardness range of the vibration damping component 4 constitute its core advantage in vibration control of the compressor's gas-liquid separator. The thickness of the vibration damping component 4 is designed between 1mm and 2mm, ensuring sufficient material volume to absorb and disperse the vibration energy generated by the airflow impact without excessively increasing the overall weight and volume of the separator, maintaining a lightweight and compact structure, which facilitates equipment installation and maintenance. This thickness range allows the rubber material to exhibit optimal damping performance at different vibration frequencies, reducing not only the vibration of the support frame but also effectively reducing structural noise between the component and the separator housing 1, thus improving the quietness of compressor operation.

[0066] Meanwhile, the hardness range of vibration damping component 4 is set between 30 and 70 Shore A. This range covers soft to medium-hard rubber materials, allowing it to meet the flexible buffering needs of low-pressure areas while maintaining structural rigidity and stability under high-pressure impacts. Lower hardness values ​​better absorb low-frequency vibrations, while higher hardness values ​​are more effective at combating high-frequency vibrations. This dynamic adaptability ensures that the vibration damping component can perform excellent vibration absorption and noise reduction under various operating conditions, protecting the filter support and housing from vibration damage and extending the service life of the equipment.

[0067] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0068] First, by setting a vibration-absorbing structure 3 on the filter support 2, the vibration-absorbing chamber 31 of the vibration-absorbing structure 3 is filled with vibration-absorbing particles 33 with a high damping ratio. Whether it is polymer particles (damping ratio ≥ 0.3), metal microspheres (particle size 0.5mm~2mm, material such as stainless steel, titanium alloy), or composite particles of both, they can dissipate a large amount of vibration energy through the collision between particles and the deformation of the material itself when the filter support 2 is impacted by airflow. This effectively suppresses high-frequency and low-frequency vibrations, reduces noise levels, and improves the operational stability of the equipment.

[0069] Secondly, the reasonable filling density (30%~70%) of the vibration-absorbing particles 33 filling cavity ensures sufficient energy conversion and gas flow balance between particles, avoiding gas channel blockage or decreased vibration absorption efficiency due to overfilling, and maintaining the high efficiency of the gas-liquid separation process. Furthermore, the vibration-damping component 4 (1mm~2mm thick, 30-70 Shore A hardness, preferably rubber) added between the filter support 2 and the separator housing 1 not only further absorbs the remaining vibration energy but also provides additional flexible support for the filter support 2, reducing hard contact, preventing secondary entrainment of droplets, and improving the gas-liquid separation accuracy.

[0070] Furthermore, through optimized design, this technical solution extends the service life of the filter support 2 and the vibration damping component 4, reduces equipment maintenance costs, and enhances the stability and durability of the overall structure. The use of rubber vibration damping component 4, combined with its suitable hardness range, ensures the adaptability of the equipment under different operating conditions, maintaining good vibration damping performance even under extreme conditions.
