Description

Technical Field

[0001] The utility model belongs to the technical field of compressors, and particularly relates to a liquid distributor bracket and a compressor assembly. Background Art

[0002] At present, low-noise vibration compressors are the mainstream trend in the development of compressors. Generally, the liquid distributor is the component with the largest vibration in the compressor. One of the main reasons for its large vibration is the low-frequency modal resonance of the liquid distributor. The first-order modal frequency of the liquid distributor of the existing technology compressors is generally around 300 Hz, which easily causes low-frequency resonance of the liquid distributor. The low-frequency resonance can be avoided by increasing the modal frequency of the liquid distributor, or the damping ratio can be increased in the resonance area to reduce the vibration of the liquid distributor, thereby reducing the noise and vibration of the compressor.

[0003] The related technology discloses a liquid receiver bracket and a compressor including the same. Referring to Figure 1 As shown, the bracket realizes multi-point contact connection with the liquid receiver through multiple support arms, shortens the span of the fixed position of the liquid receiver, ensures the upper stiffness of the liquid receiver, and improves the lower mode at the same time, thereby reducing the vibration and noise radiation of the liquid receiver. However, this bracket structure ignores the key factors affecting the low-frequency modal frequency of the liquid receiver, that is, the limited supporting area of the rubber pad between the bracket and the liquid distributor. Therefore, although this structure can increase the low-frequency modal frequency of the liquid receiver, the improvement effect is limited.

[0004] The related technology also discloses a liquid distributor bracket and a compressor assembly. Referring to Figure 2 As shown, the bracket structure extends in the circumferential direction of the liquid distributor, but the supporting area of the rubber pad between the bracket and the liquid distributor is limited, and the connection stiffness in the radial direction between the liquid distributor and the compressor is limited. The improvement of both the modal frequency and the damping ratio in the resonance area of the liquid distributor is limited.

[0005] Since the liquid distributor bracket in the prior art has limited improvement on the low-frequency modal frequency of the liquid distributor, resulting in technical problems such as large vibration of the liquid distributor, the present utility model researches and designs a liquid distributor bracket and a compressor assembly.

[0036] Refer to Figure 3-7 As shown, according to an embodiment of the present utility model, a liquid distributor bracket is provided, including: a first connection section 10 for connecting with a compressor 5; a second connection section 7, one end of the second connection section 7 is connected to the first connection section 10, and the other end of the second connection section 7 is connected to a third connection section 9. Starting from one end of the second connection section 7, the second connection section 7 extends radially along the compressor 5. Starting from the starting point of the second connection section 7, the extending directions of the first connection section 10 and the third connection section 9 are opposite, and the third connection section 9 is used to connect with a liquid distributor 6; at least two fourth connection sections 1 and a pressing plate 2, the fourth connection sections 1 are used to fix the first connection section 10, a fifth connection section 8 is connected to the fourth connection sections 1, and the end of the pressing plate 2 can be connected to the fifth connection section 8, and the liquid distributor 6 is located between the pressing plate 2 and the fifth connection section 8. In this technical solution, through the second connection section 7 and the fourth connection section 1, the length of the fourth connection section 1 is relatively long, which improves the connection stiffness between the liquid distributor and the compressor in the radial direction, enhances the damping ratio in the resonance region, ensures the distance between the liquid distributor shells, and ensures the consistency of the liquid distributor welding. The third connection section 9 achieves the purpose of greatly increasing the low-frequency modal frequency of the liquid distributor, avoiding low-frequency resonance, and reducing the noise and vibration of the compressor. In the liquid distributor bracket of the present utility model, the fourth connection section 1, the second connection section 7, the fifth connection section 8, the third connection section 9, and the first connection section 10 are integrally formed.

[0037] In some embodiments, the first connection section 10 and the third connection section 9 are arc-shaped, and the opening directions of the first connection section 10 and the third connection section 9 are opposite. The central axes of the compressor 5, the liquid distributor 6, the first connection section 10, and the third connection section 9 are parallel. Along the circumferential direction of the first connection section 10, the fourth connection sections 1 are located on both sides of the first connection section 10. In this technical solution, the central axes of the compressor 5, the liquid distributor 6, the first connection section 10, and the third connection section 9 are parallel. Starting from one end of the second connection section 7, the second connection section 7 extends radially along the compressor 5. Further, the second connection section 7 is perpendicular to the central axis of the compressor 5, which improves the tangential swing modal frequency of the liquid distributor and is beneficial to further reducing the vibration and vibration noise of the compressor and the liquid distributor. The third connection section 9 is an arc-shaped plate, and the third connection section 9 matches the outer peripheral wall of the liquid distributor; the first connection section 10 is an arc-shaped plate, and the first connection section 10 matches the outer peripheral wall of the compressor.

[0038] In some embodiments, there is an included angle between the fifth connecting section 8 and the fourth connecting section 1, and the included angle is an obtuse angle. In this technical solution, due to the included angle between the fifth connecting section 8 and the fourth connecting section 1 being an obtuse angle, it is convenient for the fifth connecting section 8 to be connected to the pressing plate 2. The pressing plate 2 and the fifth connecting section 8 can be connected by bolts or welding. Through the fifth connecting section 8 and the third connecting section 9, the low-frequency modal frequency of the liquid distributor can be effectively increased, low-frequency resonance can be avoided, and the noise and vibration of the compressor can be reduced. When the fifth connecting section 8 is connected to the pressing plate 2, the pressing plate 2, the fifth connecting section 8, and the first connecting section 10 enclose a closed ring structure, and the liquid distributor is located in the ring structure.

[0039] Further, the fourth connecting section 1 and the first connecting section 10 are connected by an arc section. The opening of the arc section is opposite to the opening direction of the included angle, and the radian of the arc section is B, where B is an obtuse angle, 90° < B < 180°. Specifically, the opening of the arc section faces the liquid distributor, the opening of the included angle faces away from the liquid distributor, the radian B is not less than the included angle, and B / included angle = 1.1 - 1. By connecting the fourth connecting section 1 and the first connecting section 10 through an arc section, with the opening of the arc section opposite to the opening direction of the included angle, and the radian of the arc section being B (an obtuse angle, 90° < B < 180°), the radian B not less than the included angle, and B / included angle = 1.1 - 1, the vibration damping effect of the fifth connecting section 8 and the fourth connecting section 1 is improved, the damping ratio in the resonance region is increased, the distance between the liquid distributor shells is ensured, the consistency of the liquid distributor welding is ensured, and the purpose of significantly increasing the low-frequency modal frequency of the liquid distributor, avoiding low-frequency resonance, and reducing the noise and vibration of the compressor is achieved.

[0040] In some embodiments, the radian of the third connecting section 9 is A, which satisfies 0° < A < 180°. The radian A is preferably 60 degrees, which can ensure the distance between the liquid distributor shells, ensure the consistency of the liquid distributor welding, increase the gasket support area between the liquid distributor and the liquid distributor, effectively increase the damping ratio in the resonance region of the liquid distributor, effectively reduce the resonance peak value of the liquid distributor, and reduce the noise and vibration of the compressor.

[0041] In some embodiments, the pressing plate 2 is arc-shaped, at least part of the pressing plate 2 is in contact with the outer wall of the liquid distributor 6, both ends of the pressing plate 2 are provided with ear seats 3, the ear seats 3 are opposite to the fifth connecting section 8, and damping members 4 are arranged between the pressing plate 2 and the liquid distributor 6 and between the third connecting section 9 and the liquid distributor 6. In this technical solution, damping members 4 are arranged between the pressing plate 2 and the liquid distributor 6 and between the third connecting section 9 and the liquid distributor 6. The damping members 4 are made of damping rubber pads. A layer of damping rubber pad is adhered to one side of the mating surface between the bracket and the liquid distributor, and then it is mated with the liquid distributor to ensure that there is a layer of damping rubber pad between the mating surface of the bracket and the liquid distributor to completely separate them. Secondly, a layer of damping rubber pad is also adhered to the inner side of the pressing plate, and there is also a layer of damping rubber pad between the mating surface and the liquid distributor to completely separate them, which can effectively increase the damping ratio in the resonance area of the liquid distributor, effectively reduce the resonance peak value of the liquid distributor, and reduce the noise and vibration of the compressor. The compressor and the bracket are connected by bolts, and the mating surface between the bracket and the compressor housing is connected by welding, so as to completely fix the liquid distributor on the compressor. The pressing plate 2 and the ear seat 3 are integrally formed.

[0042] In some embodiments, fourth connecting sections 1 are arranged on both sides of the third connecting section 9. One end of the fourth connecting section 1 is connected to the third connecting section 9, and the other end of the fourth connecting section 1 is connected to a fifth connecting section 8. In this technical solution, with reference to Figure 6 As shown, the two fourth connecting sections 1 are respectively connected to both sides of the third connecting section 9, and the vibration of the liquid distributor is transmitted jointly by the fourth connecting section 1 and the third connecting section 9, so as to achieve the purpose of greatly increasing the low-frequency modal frequency of the liquid distributor, avoiding low-frequency resonance, and reducing the noise and vibration of the compressor.

[0043] In some embodiments, along the circumferential direction of the compressor 5, fourth connecting sections 1 are arranged on both sides of the first connecting section 10. One end of the fourth connecting section 1 is connected to the third connecting section 9, and the other end of the fourth connecting section 1 is connected to a fifth connecting section 8. In this technical solution, with reference to Figure 6 As shown, the two fourth connecting sections 1 are respectively connected to both sides of the first connecting section 10, and the vibration of the liquid distributor is transmitted through the fourth connecting section 1 and the third connecting section 9 to transmit the vibration of the liquid distributor, and converge at the first connecting section 10, so as to achieve the purpose of greatly increasing the low-frequency modal frequency of the liquid distributor, avoiding low-frequency resonance, and reducing the noise and vibration of the compressor.

[0044] In some embodiments, along the axial direction of the compressor 5, the first connecting section 10 has an upper end and a lower end, and the second connecting section 7 and the third connecting section 9 are sequentially arranged at the upper end and the lower end. In this technical solution, with reference to Figure 4As shown, there are two third connecting segments 9, which can greatly increase the gasket support area between the bracket and the liquid distributor, can greatly increase the low-frequency modal frequency of the liquid distributor, effectively increase the damping ratio in the resonance area of the liquid distributor, reduce the resonance peak value of the liquid distributor, and reduce the noise and vibration of the compressor.

[0045] In some embodiments, along the axial direction of the compressor 5, the second connecting segment 7 is connected to either end of the first connecting segment 10. In this technical solution, as shown in Figure 5 for reference, there is only one third connecting segment 9. By fitting the third connecting segment 9 with the liquid distributor, the low-frequency modal frequency of the liquid distributor can be greatly increased, the damping ratio in the resonance area of the liquid distributor can be effectively increased, the resonance peak value of the liquid distributor can be reduced, and the noise and vibration of the compressor can be reduced.

[0046] Combined with Table 1, it can be seen that through simulation comparison, for the compressor liquid distributor with the prior art liquid distributor bracket structure, the first three low-frequency modal frequencies are 329 Hz, 648 Hz, and 793 Hz respectively. While for the liquid distributor bracket structure of the present invention, the first three modes of the compressor liquid distributor are 533 Hz, 1072 Hz, and 1374 Hz respectively. Through the arc segment, the fourth connecting segment 1, the fifth connecting segment 8, the second connecting segment 7, and the third connecting segment 9, the low-frequency modal frequency of the liquid distributor bracket of the present invention is greatly increased compared with the prior art liquid distributor scheme. Combined with the reference in Figure 7 As shown, where the solid line represents the transfer function response amplitude of the prior art, and the dashed line represents the transfer function response amplitude of the liquid distributor bracket of the present invention. It can be seen that the liquid distributor bracket structure of the present invention can effectively increase the low-frequency mode of the liquid distributor, enable the liquid distributor to avoid low-frequency resonance, so as to achieve the purpose of reducing the noise and vibration of the compressor.

[0047] Secondly, since the bracket greatly increases the gasket support area between it and the liquid distributor, it can effectively increase the damping ratio in the resonance area of the liquid distributor. By comparing the transfer function response with the prior art liquid distributor bracket, the peak value in the resonance area is greatly reduced, and the noise and vibration of the compressor can be effectively reduced.

[0050] The present utility model further provides a compressor assembly, which includes a compressor 5 and a liquid distributor 6. The compressor 5 and the liquid distributor 6 are connected by the above-mentioned liquid distributor bracket. In this technical solution, a layer of damping rubber pad is adhered to one side of the mating surface between the liquid distributor bracket and the liquid distributor, and then it is mated with the liquid distributor to ensure that there is a layer of damping rubber pad between the mating surfaces of the bracket and the liquid distributor to completely separate them. Secondly, a layer of damping rubber pad is also adhered to the inner side of the pressing plate, and there is also a layer of damping rubber pad between it and the mating surface of the liquid distributor to completely separate them, which can effectively increase the damping ratio of the liquid distributor in the resonance region, effectively reduce the resonance peak value of the liquid distributor, and reduce the noise and vibration of the compressor. The compressor is connected to the bracket by bolts, and the bracket is connected to the mating surface of the compressor housing by welding, so as to completely fix the liquid distributor on the compressor. It can improve the reliability of the whole compressor operation, and the noise is smaller, improving the comfort of users.
