[0045] Example 1

[0046] This embodiment provides a liquid separation device, such as Figures 1-6 As shown, the liquid separating device includes a liquid separating head assembly 1, a liquid separating rotor assembly 2 and an end cover 3. The liquid separating rotor assembly 2 is located in the liquid separating head assembly 1, and the end cover 3 is covered on the liquid separating rotor assembly 2; the liquid separating head assembly 1 has a plurality of liquid separating cavities 11, and a plurality of spiral channels 21 are opened on the surface of the liquid separating rotor assembly 2. The spiral channels 21 are connected to the liquid separating cavities 11. Under the action of the spiral channels 21, the liquid separating rotor assembly 2 can rotate in the liquid separating head assembly 1.

[0047] Specifically, in this embodiment, the liquid-separating rotor assembly 2 is located inside the liquid-separating head assembly 1, and there is also a cavity inside the liquid-separating rotor assembly 2. After the liquid flows in from the bottom of the liquid-separating head assembly 1, part of the liquid will enter the cavity of the liquid-separating rotor assembly 2, and the other part of the liquid will flow in the gap between the liquid-separating head assembly 1 and the liquid-separating rotor assembly 2.

[0048] The liquid needs to enter the liquid separation head assembly 1 from the bottom of the liquid separation head assembly 1, and then be separated through multiple liquid separation chambers 11. Traditional technology either cannot guarantee the uniformity of the liquid flowing into each liquid separation chamber, or the structure is too complicated, which increases the pressure loss of the liquid.

[0049] When the liquid enters the liquid distribution head assembly 1 from the bottom, the liquid distribution rotor assembly 2 is arranged in the liquid distribution head assembly 1, and the surface of the liquid distribution rotor assembly 2 is provided with a plurality of spiral channels 21. When the liquid in the gap between the liquid distribution head assembly 1 and the liquid distribution rotor assembly 2 flows through the liquid distribution rotor assembly 2 and the liquid is unevenly distributed on the surface of the liquid distribution rotor assembly 2, the liquid will generate a tangential thrust on the inner wall of the spiral channel 21, so that the liquid distribution rotor assembly 2 rotates in the liquid distribution head assembly 1. In the process of rotation, the spiral channel 21 is in communication with the inside of the liquid distribution rotor assembly 2, so that the liquid in the cavity of the liquid distribution rotor assembly 2 is supplemented to the liquid distribution cavity 11 with insufficient liquid through the plurality of spiral channels 21, so as to balance the pressure in each liquid distribution cavity. At the same time, the rotation of the liquid distribution rotor assembly 2 can drive the gas-liquid two-phase liquid in the cavity of the liquid distribution head assembly 1 to mix fully, so as to eliminate the howling noise caused by uneven mixing of the gas-liquid two-phase flow.

[0050] In the embodiment, when the liquid distribution rotor assembly 2 is arranged in the liquid distribution head assembly 1, the top end of the liquid distribution head assembly 1 is higher than the top end of the liquid distribution rotor assembly 2. The part protruding from the top end is used to place the end cover 3. The end cover 3 can seal the liquid distribution rotor assembly 2 and the liquid distribution head assembly 1, so as to prevent the liquid from flowing out of the end of the two.

[0051] In addition, when installing, the liquid distribution rotor assembly 2 is arranged in the liquid distribution head assembly 1, and then the end cover 3 is covered. The installation process is also relatively simple.

[0052] In specific embodiments, as shown in Figure 1 , Figure 7 , Figure 8 and Figure 9 , the liquid distribution head assembly 1 comprises a liquid inlet through hole 12 and a liquid distribution head body 13. The liquid inlet through hole 12 is connected with the liquid distribution head body 13, and the liquid inlet through hole 12 is in communication with the spiral channel 21. The liquid distribution cavity 11 is arranged in the side wall of the liquid distribution head body 13.

[0053] Specifically, the liquid distribution head assembly 1 is a copper or steel casting. The liquid inlet through hole 12 is located below the liquid distribution head body 13. The liquid distribution head body 13 is a hollow structure, and the liquid distribution rotor assembly 2 is arranged in the cavity of the liquid distribution head body 13. The liquid distribution rotor assembly 2 also has a cavity. The liquid inlet through hole 12 is in communication with the cavity of the liquid distribution rotor assembly 2, and the liquid inlet through hole 12 is in communication with each liquid distribution cavity 11.

[0054] In the embodiment, the flow process of the liquid is as follows: the liquid entering the liquid inlet through hole 12, part of the liquid enters the cavity of the liquid distribution rotor assembly 2 for distribution, and the other part of the liquid flows between the gap between the liquid distribution head assembly 1 and the liquid distribution rotor assembly 2. During the flow process, the liquid distribution rotor assembly 2 is pushed to rotate by the spiral channel 21. During the rotation process, the liquid in the cavity of the liquid distribution rotor assembly 2 is supplemented to the corresponding liquid distribution cavity 11 through the spiral channel 21.

[0055] In specific embodiments: the liquid distribution head body 13 is a circular truncated cone structure, the smaller diameter end of which is in communication with the liquid inlet through hole 12, and the liquid distribution cavity 11 is arranged in the side wall of the circular truncated cone structure, the upper end of which extends to the upper surface of the circular truncated cone structure, and the lower end of which extends to the liquid inlet through hole 12.

[0056] In some embodiments, the liquid inlet through hole 12 and the liquid distribution head body 13 are integrally formed, and the liquid distribution head body 13 can also be a cylindrical structure.

[0057] In specific embodiments: as shown in Figure 4 , the liquid distribution cavity 11 is a stepped through hole, and the axis of the stepped through hole is parallel to the generatrix of the circular truncated cone structure; the liquid distribution cavity 11 is a stepped through hole, which includes a third hole at the lower end and a fourth hole at the upper end, and the third hole has a larger radius, which is used as an output pipe fitting end to communicate with other cavities requiring liquid.

[0058] In specific embodiments: as shown in Figure 4 , the liquid inlet through hole 12 is a stepped hole; the liquid distribution cavity 11 is a stepped hole, which includes a first hole at the lower end and a second hole at the upper end, and the second hole has a larger radius, which is used to connect with external pipelines or cavities, so that the liquid can flow smoothly into the liquid inlet through hole 12.

[0059] In specific embodiments: as shown in Figure 1 and Figure 8 , the liquid distribution head assembly 1 further comprises a fitting cavity 14 arranged inside the liquid distribution head body 13, and the liquid distribution rotor assembly 2 is located in the fitting cavity 14.

[0060] In addition, the number of liquid distribution cavities 11 is the same as the number of spiral channels 21, which is used to distribute the liquid in the liquid distribution rotor assembly 2 to the corresponding liquid distribution cavities 11 through the spiral channels 21.

[0061] In addition, the liquid distribution head assembly 1 has a fitting groove 15 at the top, and the end cover 3 is clamped in the fitting groove 15, which plays a sealing role for each cavity in the liquid distribution device.

[0062] Specifically, the liquid distribution head assembly 1 provided in the embodiment mainly comprises a liquid distribution cavity 11, a liquid inlet through hole 12, and a matching cavity 14. In addition, in order to match the end cover 3 and the sealing assembly 4, the liquid distribution head assembly 1 further comprises a matching groove 15 and a threaded hole 16. The liquid distribution cavity 11 is a stepped through hole, which serves as an outlet pipe matching port and a liquid outlet passage of the liquid distribution head, and is in communication with other cavities of the liquid distribution head assembly 1. The matching cavity 14 is located at the center of the liquid distribution head assembly 1 and is in communication with the liquid distribution cavity 11 and the liquid inlet through hole 12, respectively. The shape of the matching cavity 14 matches the shape of the outer shape of the liquid distribution rotor assembly 2. The matching groove 15 is located at the opening position of the matching cavity 14 and mainly serves as a matching groove of the end cover 3 and the sealing assembly 4. The liquid inlet through hole 12 is a stepped hole, which serves as a liquid inlet passage and is in communication with other cavities of the liquid distribution head assembly. The threaded hole 16 is used to fix the end cover 3 and the sealing assembly 4, so as to seal the internal cavities of the liquid distribution head assembly 1.

[0063] In specific embodiments, as shown in Figure 1 、 Figure 10 、 Figure 11 and Figure 12 , the liquid distribution rotor assembly 2 comprises an integrally formed first body 22 and a second body 23. The first body 22 is a columnar structure, and the second body 23 is a circular truncated cone structure. The circular truncated cone structure is connected to the columnar structure at the end with a larger diameter. The spiral passage 21 is formed on the outer surface of the second body 23 and extends to the outer surface of the first body 22.

[0064] That is, the upper part of the liquid distribution rotor assembly 2 is a columnar structure, and the lower part is a circular truncated cone structure. The diameter of the lower part gradually decreases, which is more conducive to the rotation of the liquid distribution rotor assembly 2.

[0065] In specific embodiments, the liquid distribution rotor assembly 2 further comprises a plurality of communication grooves 24. The communication grooves 24 are formed on the surface of the first body 22 and are connected to the spiral passages 21 one by one. A central through hole 25 is formed in the liquid distribution rotor assembly 2. One end of the central through hole 25 is in communication with the liquid inlet through hole 12, and the other end is in communication with the spiral passage 21 through the communication groove 24. In addition, the central through hole 25 is also connected to the liquid inlet through hole 12. In this way, the central through hole 25 and the liquid inlet through hole 12 are in communication and serve as the main refrigerant passage of the liquid distribution device, which is used to supplement the refrigerant of the refrigerant sub-passage composed of the liquid distribution cavities 11. Specifically, under the rotation of the liquid distribution rotor assembly 2, the refrigerant in the central through hole 25 flows into the spiral passage 21 through the communication groove 24. Since the spiral passage 21 is in communication with the liquid distribution cavities 11, the refrigerant in the spiral passage 21 can be distributed into the corresponding liquid distribution cavities 11.

[0066] In addition, the setting of the central through hole 25 reduces the overall weight of the liquid distribution rotor assembly 2, thereby reducing the rotational inertia.

[0067] The liquid distribution rotor assembly 2 provided by the embodiment is a core structure for realizing uniform liquid distribution of the liquid distribution head, has a cylindrical shape, a bottom in a circular table structure, and a material consistent with the liquid distribution head assembly 1. The main structure of the liquid distribution rotor assembly 2 includes a spiral channel 21, a communication groove 24, and a central through hole 25. The spiral channels 21 are uniformly distributed on the circular table part of the liquid distribution rotor assembly 2 and can extend to the columnar part or not, and the number of the spiral channels 21 is consistent with the number of the liquid distribution cavities 11. The spiral channels 21 mainly function to distribute the refrigerant entering the liquid distribution head assembly 1 into each of the liquid distribution cavities 11, to generate a tangential pushing action on the inner wall of the spiral channel 21 in the case of uneven refrigerant flow and uneven pressure distribution, thereby enabling the liquid distribution rotor assembly to rotate, and to balance the pressure of the refrigerant in each of the spiral channels 21. The communication grooves 24 are uniformly distributed on the outer surface of the columnar part of the liquid distribution rotor assembly 2. The communication grooves 24 mainly function to communicate the central through hole 25 with the spiral channel 21, to balance the pressure in the communication grooves 24 and the spiral channel 21, and to generate a liquid film between the liquid distribution rotor assembly 2 and the liquid distribution head assembly 1 to reduce the friction between the liquid distribution rotor assembly 2 and the liquid distribution head assembly 1. The central through hole 25 is located at the center of the liquid distribution rotor assembly 2, is in communication with the liquid distribution inlet through hole 12 at one end, and is connected with the spiral channel 21 at the other end through the communication groove 24, and is used to balance the pressure in the communication groove 24 and the spiral channel 21.

[0068] In specific embodiments, as shown in Figure 10 , in order to enable the liquid to flow better from the central through hole 25 into the communication groove 24, the top surface and the side surface of the first body 22 are transitioned through a circular arc 26, which can guide the liquid and reduce pressure loss.

[0069] In specific embodiments, as shown in Figure 13 and Figure 14 , the lower surface of the end cover 3 is provided with a guide groove 31, which is clamped on the top of the liquid distribution rotor assembly 2. The guide groove 31 is fitted with the shape of the top of the liquid distribution rotor assembly 2, that is, fitted with the circular arc 26, which can better realize cooperation, that is, position the liquid distribution rotor assembly 2.

[0070] In specific embodiments, the liquid distribution device further includes a sealing assembly 4, which is located between the end cover 3 and the liquid distribution head assembly 1.

[0071] Specifically, as shown in Figure 1 , the sealing assembly 4 is a sealing ring, which is fixed with the end cover 3 through a bolt 5, and the sealing ring and the end cover 3 are embedded in the cooperation groove 15 to seal each cavity in the liquid distribution head assembly 1.

[0072] The assembly process of the liquid distribution device provided by the embodiment is as follows: the liquid distribution rotor assembly 2 is placed into the cavity of the liquid distribution head assembly 1, and then the sealing assembly 4 and the end cover 3 are placed in sequence, and then fastened through the bolt 5. The disassembly process is opposite to the assembly process.

[0073] The liquid distribution device provided by the embodiment can generate pressure difference in each spiral channel 21 of the liquid distribution rotor assembly 2 when the liquid is unevenly distributed in the liquid distribution head assembly 1, thereby generating tangential force on the liquid distribution rotor assembly 2, and making the liquid distribution rotor assembly 2 rotate in the matching cavity 14 of the liquid distribution head assembly 1, so as to balance the pressure in each liquid distribution cavity 11. Meanwhile, when the liquid distribution rotor assembly 2 rotates, it can drive the gas-liquid two-phase refrigerant in the cavity of the liquid distribution head assembly 1 to fully mix, thereby eliminating the howling noise caused by uneven mixing of the gas-liquid two-phase flow. At the same time, the refrigerant in the communication groove 24 and the central through hole 25 flows into the liquid distribution cavity 11 with insufficient refrigerant to supplement, so that the refrigerant flow and pressure distribution in each liquid distribution cavity 11 of the liquid distribution head assembly 1 reach dynamic balance. In addition, the liquid distribution device provided by the embodiment has simple structure and good stability, and the assembly and maintenance and disassembly are relatively simple.

[0078] The above is only the preferred embodiment of the present application, and does not limit the present application in any form.
