Description

Technical Field

[0001] The present application belongs to the technical field of compressors, and in particular relates to a liquid distributor assembly, a compressor and an air-conditioning system. Background Art

[0002] In current evaluations of rotor compressors, existing vibration tests have revealed that vibration levels at the upper portion of the liquid distributor often exceed specified limits during high-frequency testing. This is because the filter screen in traditional spinning-type liquid distributors is secured by forming two grooves in the distributor housing during spinning. This can easily cause the screen screen to distort, especially when two-phase flow continuously impacts the filter assembly from the top inlet of the distributor downward, resulting in excessive vibration. This situation is particularly common in smaller models. Therefore, with the trend toward miniaturization of compressors, a solution to this vibration issue is urgently needed to meet compressor development needs. Summary of the Invention

It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in a sequence other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0028] See also Figures 1 to 5 As shown, according to an embodiment of the present application, a liquid dispenser assembly includes:

[0029] A housing 1 and a filter assembly 2, wherein the filter assembly 2 is mounted inside the housing 1 so as to be movable along the axial direction of the housing 1;

[0030] The elastic member 4 can maintain the filter assembly 2 at a preset position.

[0031] The present application sets the liquid distributor housing 1 and the filter assembly 2 to be axially movable, and maintains the position of the filter assembly 2 by the elastic member 4, so that when the two-phase flow impacts at high speed, the filter assembly 2 can buffer the impact force received by the elastic member 4 and reduce vibration.

[0032] In some embodiments, the filter assembly 2 includes a support plate 21 and a filter 22 thereon, and the periphery of the support plate 21 is slidably engaged with the inner wall of the shell 1; a plurality of guide holes 24 are provided on the circumference of the support plate 21.

[0033] A filter screen 22 is mounted on the support plate 21, which is a traditional structure. The two-phase flow is filtered through the filter screen 22 and then flows out through the guide hole 24. In this application, the periphery of the support plate 21 and the inner wall of the shell 1 are axially slidably matched to buffer the impact force of the two-phase flow on the filter assembly 2 and reduce vibration.

[0034] In some embodiments, an inner convex strip extending axially is provided on the inner wall surface of the shell 1, and a groove corresponding to the inner convex strip is provided on the periphery of the support plate 21.

[0035] The connection structure between the support plate 21 and the shell 1 is specifically an axially extending convex strip on the inner wall of the shell 1 and a matching groove on the periphery of the support plate 21; similarly, it can also be set as a groove on the inner wall of the shell 1 and a protrusion on the periphery of the support plate 21.

[0036] The convex strips and the grooves are provided in a plurality of evenly distributed circumferential directions; however, in order to facilitate positioning and installation, more convex strips and grooves can be provided in unevenly distributed directions.

[0037] In some embodiments, a flow guide 25 is provided on the lower side of the flow guide hole 24 . The inner wall surface of the flow guide 25 includes a quarter spherical arc surface, and the fluid passing through the flow guide hole 24 flows down along the inner wall surface.

[0038] A flow guide 25 is provided on the lower side of the flow guide hole 24. The flow guide 25 has an inner wall surface with a quarter spherical arc surface. When the fluid flows down along the inner wall surface, the quarter spherical arc surface changes the direction of the fluid impact. In particular, the flow guide 25 is provided on the symmetrical flow guide holes 24, and the directions of the fluid flowing out of the inner wall surface in the symmetrical flow guide holes 24 are opposite. This will generate a rotational torque, so that the filter assembly 2 and the elastic member 4 fit tightly, reducing operating vibration.

[0039] In some embodiments, the housing 1 is vertically arranged, and an entrance is provided at its top; the support plate 21 is provided with a recessed portion 23 facing the entrance.

[0040] A concave portion 23 is provided on the support plate 21 facing the two-phase flow inlet, so that a part of the two-phase flow impacting the support plate 21 will rebound and the vortex formed by the continuous two-phase flow impact will offset a part, thereby reducing the impact force and vibration.

[0041] In some embodiments, the liquid dispenser assembly further includes an exhaust pipe 3 , which is disposed below the filter assembly 2 ; the elastic member 4 is located between the inlet end of the exhaust pipe 3 and the lower recess 23 .

[0042] The elastic member 4 is arranged between the inlet end of the exhaust pipe 3 and the lower recess 23. The exhaust pipe 3 serves as a support seat for the elastic member 4. No additional supporting structure is required, which makes the overall structure simple.

[0043] Preferably, the elastic member 4 includes a spring 41 ; a vibration-damping structure 42 is provided between the lower recess 23 and the spring 41 , and a radial channel is provided on the vibration-damping structure 42 .

[0044] When the elastic member 4 is a spring 41, the lower recess 23 of the support plate 21 forms a spring 41 connection with the upper end of the exhaust pipe 3. When the pressure is too high, the filter assembly 2 moves downward, the squeezing spring 41 is compressed, and the gap of the spring 41 is blocked, which is equivalent to extending the length of the exhaust pipe 3. The gas enters the exhaust pipe 3 from the radial channel of the vibration reduction structure 42, increasing the pressure loss along the way. Then, the suction pressure decreases at high frequencies, causing the suction and exhaust pressure difference to increase, the effective suction volume to increase, and the cooling capacity to increase. When the pressure decreases, the spring 41 returns, which is equivalent to shortening the exhaust pipe 3, reducing the pressure loss along the way, and keeping the low-frequency capacity unchanged, thereby ensuring that the low frequency is not attenuated and the high-frequency capacity is improved.

[0045] A vibration-damping structure 42 is provided on the top of the spring 41 to buffer the force between the filter assembly 2 and the spring 41. At the same time, under the action of the guide member 25, the spring 41 is in close contact with the vibration-damping structure 42 to reduce the vibration of the filter assembly 2 when it moves up and down.

[0046] In some embodiments, the vibration-damping structure 42 includes a vibration-damping pad 43 and a supporting rib 44. The supporting rib 44 is arranged on the top of the spring 41, and the vibration-damping pad 43 is arranged on the supporting rib 44. A gap is provided between the vibration-damping pad 43 and the top of the spring 41 to form a radial channel.

[0047] There are usually multiple support ribs 44, which are evenly spaced on the top of the exhaust pipe 3. The vibration damping pads 43 are set on the support ribs 44, so that radial channels connecting to the exhaust pipe 3 are formed between adjacent support ribs 44, which facilitates the exhaust of the spring 41 after being compressed.

[0048] According to another aspect of the present application, a compressor is provided, comprising the liquid separator assembly as described above.

[0049] According to yet another aspect of the present application, an air conditioning system is provided, comprising the liquid distributor assembly as described above or the compressor as described above.

[0050] When the compressor is running at high frequency, the effective suction volume is reduced due to the small suction and exhaust pressure difference, resulting in a decrease in effective cooling capacity. This application improves the structure of the liquid distributor to achieve the effect of vibration reduction on the upper part of the liquid distributor, while also improving the capacity during high frequency operation.

[0051] The filter assembly 2 is connected by cooperating with the inward convex vertical bars on the liquid dispenser housing 1. The convex vertical bars on the liquid dispenser housing 1 can clamp one end of the liquid dispenser housing 1 through a spinning machine and be extruded through a mold. A groove is set at the corresponding position on the periphery of the filter assembly 2, which can be integrally formed through a composite mold during bending. One end has two grooves to ensure the installation angle. The two are installed in coordination. This structure allows the filter assembly 2 to move up and down along the axial direction, and a rubber pad and a spring 41 are set under the filter assembly 2 to avoid vibration caused by high-frequency impact.

[0052] When the compressor is running, the two-phase flow impacts the filter assembly 2 from the top pipe of the liquid distributor, and the axial part impacts the lower recess 23 in the middle of the support plate 21 in the filter assembly 2 after passing through the filter 22. The recess 23 has a spherical structure. When the two-phase flow impacts the upper surface, part of it will rebound and the vortex formed by the continuous two-phase flow impact will offset part of it. At the same time, due to the continuous impact of the two-phase flow on the support plate 21, the entire filter assembly 2 is pushed downward, pushing the spring 41 to compress.

[0053] During high-frequency operation, the two-phase flow passes through the filter 22 and enters the bottom of the filter assembly 2 from the guide hole 24 (located on the periphery of the recessed portion 23 of the support plate 21). The fluid flowing vertically downward will impact the spherical surface through the quarter-spherical guide holes 24 symmetrically arranged at 0°, 30°, and 60° along the radial direction of the shell 1, and the flow direction will be changed by the guide holes 24. The fluid will exert a lateral force on the arc surface of the spherical surface. The symmetrical lateral forces in the two directions will form a pair of rotational torques around the axis, which will make the dispenser closer to the dispenser rubber pad and reduce the vibration transmission during operation. After the fluid enters the bottom of the filter assembly 2, it enters the exhaust pipe 3 through the gap between the springs 41, completing the compressor suction process. When the pressure increases further, the spring 41 will be further compressed to reach the maximum When the compressor is compressed, the gap between the springs 41 is blocked. At this time, the lower recess 23 pushes the rubber cushion and the support rib 44. At this time, the fluid enters the exhaust pipe 3 through the channel next to the support rib 44. At this time, the length of the exhaust pipe 3 plus the length of the compression spring 41 increases the length of the exhaust pipe 3, increases the pressure loss along the way, reduces the suction pressure during high-frequency operation, ensures the suction and exhaust pressure difference of the compressor, increases the effective suction volume, and improves the high-frequency operation cooling capacity; when switching to low-frequency operation, the two-phase flow impact pressure becomes smaller, which is not enough to completely push the spring 41 to reach the maximum compression. The spring 41 pushes the filter assembly 2 upward, and the fluid is sucked in from the gap of the spring 41. The actual length of the exhaust pipe 3 remains unchanged, which does not affect the low-frequency operation, ensures that the low frequency is not attenuated, and the high-frequency capacity is improved.
