[0029] In the description of the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connect," and "fixed" should be understood in a broad sense. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; and internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0030] The core idea of ​​the present invention is to provide an isolation component and a liquid reservoir to extend the flow path of the refrigerant in the liquid reservoir, thereby effectively reducing the refrigerant flow noise and effectively improving the transmission loss of noise in a specific frequency band in the liquid reservoir, thereby changing the cavity modal frequency in the liquid reservoir to achieve the purpose of effectively suppressing the noise in the liquid reservoir.

[0031] It should be noted that the isolation member provided by the present invention can be applied to a liquid reservoir, and the isolation member is used to be mounted on the air outlet pipe in the liquid reservoir, and the isolation member is used to separate at least a part of the inner cavity of the liquid reservoir into a first cavity and a second cavity, and the first cavity is close to the location of the air intake port of the liquid reservoir.

[0032] <Example 1>

[0033] Please refer to Figures 1 to 3 ,in, Figure 1 A schematic diagram of the three-dimensional structure of the isolation element provided in the first embodiment of the present invention is shown schematically; Figure 2 A side view of the isolation element provided in the first embodiment of the present invention is schematically shown; Figure 3 A cross-sectional view of the isolator provided in the first embodiment of the present invention along the AA direction is schematically shown. Figures 1 to 3 As shown, the isolation member includes a partition 100, a plurality of cavities 200, a liquid inlet 211 and a liquid outlet 221. The cavity 200 is provided on the partition 100. The center of the partition 100 is provided with an inner circular through hole, which is sleeved on the outlet pipe 320. The cavity 200 is connected to the first cavity through the liquid inlet 211, and the cavity 200 is connected to the second cavity through the liquid outlet 221. Thus, the flow path of the refrigerant in the liquid reservoir can be extended through the cavity 200, thereby effectively reducing the refrigerant flow noise. The cavity 200 can also effectively improve the transmission loss of the noise in a specific frequency band in the liquid reservoir, thereby changing the cavity modal frequency in the liquid reservoir and further suppressing the noise. For example, under the specific parameters of a scheme, the first-order modal frequency of the liquid reservoir is reduced by two times, which can effectively avoid the frequency band where problems are prone to occur. In addition, the isolation member provided by the present invention is easy to process, has low cost, and is conducive to production and manufacturing.

[0034] Preferably, the ratio of the effective flow path of the refrigerant in the cavity 200 to the thickness of the partition 100 is η, where η>1. When η>10, the transmission loss of the refrigerant can be more effectively increased, thereby being more conducive to improving noise. It should be noted that the function of the cavity 200 is to increase the refrigerant flow path and reduce the low-order cavity modal frequency; a certain gap can be left between the partition 100 and the outlet pipe 320, or a certain gap can be left between the partition 100 and the inner wall of the cylinder 300 of the liquid reservoir; the liquid inlet 211, liquid outlet 221 on the partition 200 and the cavity 200 or other through holes provided need to ensure that more than 50% of the refrigerant can enter the second cavity from the first cavity.

[0035] Preferably, if Figure 1As shown, the partition 100 includes a first partition 110 and a second partition 120 spliced ​​together, and the cavity 200 is arranged along the circumference of the first partition 110 and the second partition 120, and the cavity 200 is formed by splicing the first partition 110 and the second partition 120; the first partition 110 and the second partition 120 are both annular structures, and the first partition 110 and the second partition 120 are provided with inner circle through holes in the center for being sleeved on the air outlet pipe 320, and the outer circle of the first partition 110 and / or the second partition 120 is used to be connected to the inner wall of the cylinder 300 of the liquid reservoir, and the first partition 110 is provided with a liquid inlet 211, which is respectively connected to the first cavity and the cavity 200, and the second partition 120 is provided with a liquid outlet 221, which is respectively connected to the second cavity and the cavity 200. Thus, the size and shape of the cavity 200 formed by the mutual splicing are controllable, which is conducive to increasing the transmission loss of noise of a specific frequency within the liquid reservoir, and the first partition 110 effectively isolates the first cavity and the second cavity, so that the first cavity and the second cavity are connected only through the cavity 200. It should be noted that in some other embodiments, the connection between the first partition 110 and the second partition 120 can also be integrated molding or specific bonding, etc.

[0036] like Figure 1 As shown, the first partition 110 is provided with a first groove 210, and the second partition 120 is provided with a second groove 220 that is arranged to cooperate with the first groove 210. Specifically, the first groove 210 protrudes in the direction of the first cavity, and the second groove 220 protrudes in the direction of the second cavity. The notch of the first groove 210 and the notch of the second groove 220 are arranged opposite to each other, and the first groove 210 and the second groove 220 cooperate to form the cavity 200. Thus, by splicing the first partition 110 and the second partition 120 with each other, the first groove 210 and the second groove 220 form the cavity 200, which is beneficial to the processing and manufacturing of the isolation component and saves process costs. The liquid inlet 211 is opened on the first groove 210, and the liquid outlet 221 is opened on the second groove 220. More preferably, the liquid inlet 211 and the liquid outlet 221 are evenly distributed relative to the inner circular through hole of the partition 100. In addition, the method of forming the cavity 200 of the isolation part includes but is not limited to the above-mentioned splicing method, and the first groove body provided with the first groove 210 and / or the second groove body provided with the second groove 220 can also be welded or bonded on the partition 100 to form the cavity 200.

[0037] like Figure 3As shown, the cavity 200 is an annular structure with a circular cross-section, and the first partition 110, the second partition 120, and the cavity 200 are concentrically arranged. Thus, this arrangement allows the first groove 210 on the first partition 110 and the second groove 220 on the second partition 120 to better match, forming the annular cavity 200, while also facilitating an increased refrigerant flow path and reduced noise transmission loss.

[0038] It should be noted that, in some other embodiments, the cross-section of the cavity 200 can also be semicircular, square, etc.; the cavity 200 can also be distributed along the radial direction of the partition 100, spirally distributed along the axis of the partition 100, or radially distributed along the center of the partition 100, etc.; the shape of the liquid inlet 211 and the liquid outlet 221 can be circular, triangular, polygonal, plum blossom-shaped or elliptical, etc.; the positions of the liquid inlet 211 and the liquid outlet 221 can be arranged at any position of the isolation member, but need to be connected to the cavity 200, and when the position of the liquid outlet 221 is close to the air outlet pipe 320 of the liquid reservoir, the noise reduction effect is better, and when the number of the liquid outlets 221 is at least two, the noise reduction effect is better when at least two liquid outlets 221 are evenly distributed along the circumference of the partition 100.

[0039] <Example 2>

[0040] Please refer to Figure 4 , which schematically shows the structural diagram of the isolation member provided by the second embodiment of the present invention. Figure 4 As shown, the difference between this embodiment and all the above-mentioned embodiments is that the cavity 200 of this embodiment is not a circular structure, but a curved pipe structure. The liquid inlet 211 is provided at the first end of the cavity 200, the liquid inlet 211 is located on the first partition 110, and the opening faces the first cavity; the liquid outlet 221 is provided at the second end of the cavity 200, the liquid outlet 221 is located on the second partition 120, and the opening faces the second cavity. The distance between the first end of the cavity 200 and the center of the inner circular through hole of the partition 100 is farther than the distance between the second end of the cavity 200 and the center of the inner circular through hole of the partition 100. Therefore, the cavity 200 structure provided in this embodiment can also extend the flow path of the refrigerant in the liquid reservoir, thereby effectively reducing the refrigerant flow noise. Through the cavity 200, the transmission loss of noise in a specific frequency band in the liquid reservoir can also be effectively improved, thereby changing the cavity modal frequency in the liquid reservoir and further suppressing the noise.

[0041] <Example 3>

[0042] Please refer to Figure 5, which schematically shows the structure of the isolation member provided by the third embodiment of the present invention. Figure 5 As shown, the difference between this embodiment and the above-mentioned embodiment 1 is that a first groove 210 is provided on the first partition 110 of this embodiment, and the first groove 210 cooperates with the second partition 120 to form the cavity 200, that is, the second groove 220 that cooperates with the first groove 210 is not provided on the second partition 120.

[0043] Preferably, there are at least two first grooves 210, and the at least two first grooves 210 are symmetrically distributed around the center of the first partition 110. The outer circle of the second partition 120 is connected to the inner wall of the barrel 300 of the liquid reservoir. The diameter of the inner circular through hole of the second partition 120 is larger than the diameter of the inner circular through hole of the first partition 110. The first groove 210 extends circumferentially along the inner circular through hole of the first partition 110. The end of the first groove 210 closer to the inner circular through hole of the first partition 110 extends to be exposed within the inner circular through hole of the second partition 120 to form the liquid outlet 221. The liquid inlet 211 is provided at the end of the first groove 210 away from the center of the first partition 110. Specifically, the central axis of the first groove 210 gradually decreases relative to the center of the inner circular through hole of the first partition 110. Therefore, the cavity 200 structure provided in this embodiment can also extend the flow path of the refrigerant in the liquid reservoir, thereby effectively reducing the refrigerant flow noise. Through the cavity 200, the transmission loss of noise in a specific frequency band in the liquid reservoir can also be effectively improved, thereby changing the cavity modal frequency in the liquid reservoir and further suppressing noise.

[0044] It should be noted that, in some other embodiments, corresponding to the first embodiment, the first groove 210 may also be arranged in a circular ring shape, and the first groove 210, the first partition 110 and the second partition 120 are arranged concentrically.

[0045] <Example 4>

[0046] Please refer to Figure 6 , which schematically shows the structure of the isolation member provided by the fourth embodiment of the present invention. Figure 6As shown, the difference between this embodiment and the above-mentioned embodiment 1 is that the second partition plate 120 of this embodiment is provided with a second groove 220, which cooperates with the first partition plate 110 to form the cavity 200. That is, the first partition plate 110 is not provided with a first groove 210 that cooperates with the second groove 220. Therefore, the cavity 200 structure provided in this embodiment can also extend the flow path of the refrigerant in the liquid reservoir, thereby effectively reducing the refrigerant flow noise. The cavity 200 can also effectively improve the transmission loss of noise in a specific frequency band within the liquid reservoir, thereby changing the cavity modal frequency within the liquid reservoir and further suppressing noise.

[0047] Similar to the second embodiment, the cavity 200 formed by the cooperation of the second groove 220 and the first partition 110 is a curved pipe structure, the liquid inlet 211 is provided on the first partition 110, and is connected to the first end of the second groove 220, that is, the end at which the central axis of the second groove 220 is farther from the center of the inner circular through hole of the second partition 120; the liquid outlet 221 is provided at the second end of the second groove 220 away from the liquid inlet 211, that is, the end at which the central axis of the second groove 220 is closer to the center of the inner circular through hole of the second partition 120. Therefore, the cavity 200 structure provided in this embodiment can also extend the flow path of the refrigerant in the liquid reservoir, thereby effectively reducing the refrigerant flow noise. Through the cavity 200, the transmission loss of noise in a specific frequency band in the liquid reservoir can also be effectively improved, thereby changing the cavity modal frequency in the liquid reservoir and further suppressing the noise.

[0048] <Example 5>

[0049] Please refer to Figure 7 , which schematically shows the structure of the isolation member provided by the fifth embodiment of the present invention. Figure 7As shown, the difference between this embodiment and the above-mentioned embodiment 1 is that, in this embodiment, a second groove 220 is provided on the second partition 120, and the second groove 220 cooperates with the first partition 110 to form the cavity 200, that is, the first groove 210 cooperating with the second groove 220 is not provided on the first partition 110, and the number of the second grooves 220 is at least two, and at least two second grooves 220 are symmetrically distributed with the center of the second partition 120 as the symmetry center; more preferably, the distance between the central axis of each second groove 220 and the center of the inner circular through hole of the second partition 120 is gradually reduced, and the liquid inlet 211 is provided on the first partition 110, and is correspondingly arranged and connected to the first end of the second groove 220, and the first end of the second groove 220 refers to the end where the central axis of the second groove 220 is farther from the center of the inner circular through hole of the second partition 120, and the liquid outlet 221 is provided at the second end of the second groove 220 and is provided close to the center of the first partition 110. Therefore, the cavity 200 structure provided in this embodiment can also extend the flow path of the refrigerant in the liquid reservoir, thereby effectively reducing the refrigerant flow noise. Through the cavity 200, the transmission loss of noise in a specific frequency band in the liquid reservoir can also be effectively improved, thereby changing the cavity modal frequency in the liquid reservoir and further suppressing noise.

[0050] <Example 6>

[0051] The difference from the above-mentioned embodiment 1 is that the partition 100 of this embodiment includes at least two third partitions arranged at intervals, and the cavity 200 is provided between any two adjacent third partitions. The equivalent diameter D of the liquid inlet 211 and the liquid outlet 221 and the spacing H between any two adjacent third partitions satisfy the relationship: H<2D. Thus, this arrangement enables the cavity 200 formed between any two adjacent third partitions to achieve the same technical effect of the present invention, that is, it can effectively extend the flow path of the refrigerant in the liquid reservoir through the cavity 200, thereby effectively reducing the refrigerant flow noise, while improving the transmission loss of the noise in a specific frequency band in the liquid reservoir, thereby changing the cavity modal frequency in the liquid reservoir and effectively suppressing the noise. It should be noted that the equivalent diameter D of the liquid inlet 211 and the liquid outlet 221 is the average of the equivalent diameter D1 of the liquid inlet 211 and the equivalent diameter D2 of the liquid outlet 221.

[0052] Based on the same inventive concept, the present invention also provides a liquid reservoir, please refer to Figure 8 , which schematically shows the structure of the liquid storage device provided by the present invention. Figure 8As shown, the liquid reservoir includes at least one isolator as described above, a barrel 300, an outlet pipe 320, an intake pipe 310, and a filter holder 330 disposed within the barrel 300. The filter holder 330 is disposed near the intake pipe 310, which has an intake port. The filter holder 330 is configured to filter the refrigerant drawn in through the intake port. Because the liquid reservoir includes at least one isolator as described above, the liquid reservoir provided by the present invention includes all the advantages of the isolator described above, which will not be further elaborated here.

[0053] Please refer to Figure 9 , which schematically shows a comparison diagram of the simulated waveforms of the transmission loss of the liquid reservoir provided by the present invention and the existing liquid reservoir changing with frequency, wherein the vertical axis is the transmission loss of the noise and the horizontal axis is the frequency of the noise. Figure 9 It can be seen that compared with the existing liquid reservoir, the transmission loss of noise in certain specific frequency bands in the liquid reservoir provided by the present invention is greater. Therefore, the liquid reservoir provided by the present invention can effectively improve the cavity modal frequency in the liquid reservoir to increase the transmission loss of noise in specific frequency bands, thereby effectively suppressing noise.

[0054] In summary, compared with the prior art, the isolation member provided by the present invention includes a partition, a plurality of cavities, a liquid inlet and a liquid outlet, the cavity is provided on the partition, the partition is sleeved on the air outlet pipe, the cavity is connected to the first cavity through the liquid inlet, and the cavity is connected to the second cavity through the liquid outlet, thereby, the flow path of the refrigerant in the liquid reservoir can be extended through the cavity, thereby effectively reducing the refrigerant flow noise, and the transmission loss of the noise in a specific frequency band in the liquid reservoir can also be effectively improved through the cavity, thereby changing the cavity modal frequency in the liquid reservoir, further suppressing the noise, for example, under the specific parameters of a scheme, the first-order modal frequency of the liquid reservoir is reduced by two times, which can effectively avoid the frequency band where problems are prone to occur. In addition, the isolation member provided by the present invention is easy to process, has low cost, and is conducive to production and manufacturing.
