[0039] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0040] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0041] Embodiment 1

[0042] Reference Figure 1 to Figure 2 As shown, this embodiment provides a gas-liquid separator, including a cylinder 1.

[0043] Specifically, refer to Figure 1 , Figure 3 and Figure 4 As shown, the cylinder 1 is provided with an inlet 11 and an outlet 12 , and has a stacked separation chamber 13 and a liquid storage chamber 14 in the cylinder 1 , there are at least two separation chambers 13 , and at least two separation chambers 13 are arranged in sequence along the circumference of the cylinder 1 .

[0044] The separation chamber 13 located at the most upstream side is connected to the inlet 11, the separation chamber 13 located at the downstream side is connected to the adjacent separation chamber 13 located at the upstream side, and the separation chamber 13 located at the most downstream side is connected to the outlet 12, so as to sequentially separate the gas-liquid mixture entering from the inlet 11, and discharge the separated gas through the outlet 12. The specific direction of the gas-liquid mixture flowing along each separation chamber 13 can be referred to Figure 3 As shown by the arrow S in FIG. 1 , the liquid storage chamber 14 is located below the separation chamber 13 , and the bottom of each separation chamber 13 is connected to the liquid storage chamber 14 , so that the separated liquid enters the liquid storage chamber 14 .

[0045] It should be noted that the settings of the upstream side and the downstream side are defined by the flow direction of the gas-liquid mixture.

[0046] For example, refer to Figure 3 and Figure 4 As shown, it is possible to set the separation chamber 13 to include four, and the four separation chambers 13 are sequentially arranged along the circumference of the cylinder 1. In addition, a liquid hole 15 can be arranged at the bottom of the separation chamber 13 to communicate with the liquid storage chamber 14.

[0047] In specific implementation, the four separation chambers 13 can be arranged in sequence along the flow direction of the gas-liquid mixture, wherein the separation chamber 13 connected to the inlet 11 is the separation chamber 13 on the most upstream side, and along the flow direction of the gas-liquid mixture, the separation chamber 13 farthest from the separation chamber 13 on the most upstream side is the separation chamber 13 on the most downstream side, and the separation chamber 13 on the most downstream side is connected to the outlet 12.

[0048] For example, the four separation chambers 13 can be set as the first separation chamber 131, the second separation chamber 132, the third separation chamber 133 and the fourth separation chamber 134 in sequence along the flow direction of the gas-liquid mixture, wherein the first separation chamber 131 is connected to the inlet 11, the fourth separation chamber 134 is connected to the outlet 12, and the first separation chamber 131 and the second separation chamber 132, the second separation chamber 132 and the third separation chamber 133, and the third separation chamber 133 and the fourth separation chamber 134 are connected, so that the gas-liquid mixture entering through the inlet 11 can be separated by gas and liquid in the first separation chamber 131, the second separation chamber 132, the third separation chamber 133 and the fourth separation chamber 134 in sequence, so that the gas formed by the separation is discharged through the outlet 12, and the liquid enters the liquid storage chamber 14 through the liquid hole 15 at the bottom of each separation chamber 13, thereby realizing the gas-liquid separation operation.

[0049] Furthermore, by providing four separation chambers 13 for the gas-liquid mixture to circulate, the flow path of the gas-liquid mixture becomes longer, thereby increasing the gas-liquid separation time, thereby improving the gas-liquid separation effect, ensuring the normal operation of the compressor, and then ensuring the performance of the vehicle.

[0050] For example, in other implementations, the separation chamber 13 may be set to include two, three, or more than four. The specific number of separation chambers 13 may be determined according to the actual requirements of the gas-liquid separation effect. The greater the number of separation chambers 13, the better the gas-liquid separation effect. This embodiment does not make any specific limitation on this.

[0051] For example, the liquid passage hole 15 may be a rectangular hole or a circular hole. In addition, the diameter of the liquid passage hole 15 may be set according to actual needs.

[0052] In summary, in the gas-liquid separator provided in the present embodiment, the gas-liquid mixture enters the separation chamber 13 on the upstream side through the inlet 11 and then flows through each separation chamber 13 in sequence to realize the gas-liquid separator. In the process of the gas-liquid mixture hitting the cavity wall of the separation chamber 13 under the action of inertia, the liquid in the gas-liquid mixture sinks under the action of gravity and finally flows into the liquid storage chamber 14 below the separation chamber 13, while the gas in the gas-liquid mixture passes through each separation chamber 13 in sequence to realize gas-liquid separation and is discharged through the outlet 12, thereby completing a complete gas-liquid separation operation. Moreover, by providing at least two separation chambers 13 for the gas-liquid mixture to circulate, the flow path of the gas-liquid mixture becomes longer, thereby increasing the gas-liquid separation time, thereby improving the gas-liquid separation effect, ensuring the normal operation of the compressor, and then ensuring the performance of the vehicle.

[0053] Reference Figure 3 and Figure 4 As shown, in some embodiments, a gas-liquid separation port 16 can be provided between a separation chamber 13 located on the downstream side and an adjacent separation chamber 13 located on the upstream side, and a liquid blocking member 2 is provided at the gas-liquid separation port 16. The liquid blocking member 2 is located on the side of the separation chamber 13 facing the upstream side of the gas-liquid separation port 16, so that when the gas-liquid mixture flows through the gas-liquid separation port 16 of one of the separation chambers 13 to the next separation chamber 13, the liquid in the gas-liquid mixture impacts the liquid blocking member 2 and is blocked by the liquid blocking member 2, and then sinks to the bottom of the corresponding separation chamber 13 and flows into the liquid storage chamber 14, thereby improving the gas-liquid separation effect. In addition, by providing the liquid blocking member 2, the liquid in the gas-liquid mixture can also be blocked to prevent the liquid from passing through the gas-liquid separation port 16 and entering the next separation chamber 13 to affect the gas-liquid separation effect.

[0054] Reference Figure 3 and Figure 4As shown, in some embodiments, the liquid blocking member 2 may specifically be a liquid blocking plate, or the liquid blocking member 2 may also be a liquid blocking block, etc.

[0055] Reference Figure 3 and Figure 4 As shown, in some embodiments, one side of the liquid blocking member 2 facing the separation chamber 13 on the upstream side is a curved surface convex in the direction of the separation chamber 13 on the upstream side, thereby facilitating effective contact with the liquid in the gas-liquid mixture, thereby effectively blocking the liquid.

[0056] Alternatively, in other implementations, the side of the liquid blocking member 2 facing the separation chamber 13 on the upstream side may also be configured as a curved surface convex toward the direction away from the separation chamber 13 on the upstream side, which may also achieve effective blocking of the liquid.

[0057] Reference Figure 3 and Figure 4 As shown, in some embodiments, the liquid blocking member 2 is disposed at the lower edge of the gas-liquid separation port 16, so that the liquid blocking member 2 can block the liquid after effectively contacting the gas-liquid mixture.

[0058] Alternatively, in other implementations, the liquid blocking member 2 may also be disposed on the upper edge or side edge of the gas-liquid separation port 16 . The specific location of the liquid blocking member 2 may be set according to actual needs, and this embodiment does not specifically limit this.

[0059] Reference Figure 3 and Figure 4 As shown, in some embodiments, at least two liquid storage chambers 14 can be provided, and the at least two liquid storage chambers 14 are arranged in sequence along the circumference of the cylinder 1, and the two adjacent liquid storage chambers 14 are connected by a liquid through hole 44, so that the liquid separated by each separation chamber 13 can be stored by at least two liquid storage chambers 14 respectively, so that the liquid separated by each separation chamber 13 can quickly enter the corresponding liquid storage chamber 14.

[0060] In addition, refer to Figure 3 and Figure 4 As shown, the number of separation chambers 13 can be consistent with the number of liquid storage chambers 14, that is, each separation chamber 13 corresponds to one liquid storage chamber 14, and the separation chamber 13 and the corresponding liquid storage chamber 14 can be arranged opposite to each other. Alternatively, only one liquid storage chamber 14 can be arranged, and each separation chamber 13 is connected to the liquid storage chamber 14, so that the liquid separated in each separation chamber 13 enters the same liquid storage chamber 14 to achieve liquid storage.

[0061] Reference Figure 3 and Figure 4As shown, in some embodiments, the cylinder 1 further has an air outlet cavity 17, which is located below the separation cavity 13 on the most downstream side, and the bottom of the separation cavity 13 on the most downstream side is provided with an air vent 18 connected to the air outlet cavity 17, and the air outlet cavity 17 is connected to the outlet 12, so that the separated gas is discharged through the air vent 18, the air outlet cavity 17 and the outlet 12 in sequence.

[0062] In specific implementation, the gas-liquid mixture entering the separation chamber 13 on the most upstream side through the inlet 11 passes through each separation chamber 13 and finally passes through the separation chamber 13 on the most downstream side for separation, and the separated gas is finally discharged through the outlet 12. In order to further reduce the amount of liquid entrained in the gas discharged through the outlet 12, a gas outlet chamber 17 can be provided below the separation chamber 13 on the most downstream side, so that the gas entering the separation chamber 13 on the most downstream side can first pass through the vent 18 into the gas outlet chamber 17 before being discharged through the outlet 12, thereby increasing the gas discharge path, thereby further separating the liquid in the gas, and further improving the dryness of the gas discharged through the outlet 12.

[0063] In addition, the vent 18 can be a fan-shaped hole or a circular hole, and the diameter of the vent 18 can be set larger to increase the ventilation volume, so that the gas in the separation chamber 13 on the most downstream side can quickly flow through the vent 18 to the outlet chamber 17 and then be discharged through the outlet 12.

[0064] Reference Figure 1 , Figure 3 and Figure 4 As shown, in some embodiments, the gas-liquid separator also includes an air outlet pipe 4, and at least two separation chambers 13 are arranged in sequence along the circumference of the air outlet pipe 4; an air inlet 41 is provided on the cavity wall of the corresponding air outlet cavity 17 of the air outlet pipe 4, which is respectively connected to the air outlet cavity 17 and the outlet 12.

[0065] That is, the gas outlet pipe 4 can be arranged at the center of the cylinder 1, and at least two separation chambers 13 can be arranged in sequence along the circumference of the gas outlet pipe 4. Further, the gas outlet pipe 4 can be provided with an air inlet 41, which is connected to the gas outlet chamber 17 and the outlet 12, so that the gas entering the gas outlet chamber 17 is discharged through the air inlet 41 and the outlet 12 in sequence.

[0066] Reference Figure 1 , Figure 3 and Figure 4 As shown, in some embodiments, the air outlet cavity 17 and the air outlet pipe 4 can jointly form a U-shaped tube design, and the U-shaped tube and filter assembly are omitted to reduce the number of parts; at the same time, the vertical space is fully utilized to increase the effective volume of the gas-liquid separator.

[0067] In addition, the air inlet 41 can be arranged at the bottom of the air outlet pipe 4, and the area of ​​the air outlet needs to be close to the cross-sectional area of ​​the air outlet pipe 4 to avoid the throttling effect during the flow process and reduce the overall pressure drop. The area of ​​the air inlet 41 is not too much defined, and it needs to meet the gas-liquid separation capacity and the overall pressure drop requirements of the gas-liquid separator.

[0068] In some embodiments, a return oil hole 42 connected to the air outlet chamber 17 is provided on the side wall of the liquid storage chamber 14 on the most downstream side close to the air outlet chamber 17, so that under the action of the pressure difference of the imitation U-shaped tube, the refrigerant oil or engine oil in the liquid in the liquid storage chamber 14 on the downstream side can enter the air outlet chamber 17 through the return oil hole 42 and then be discharged together with the separated gas through the outlet 12 and returned to the compressor, so as to realize the recovery operation of the refrigerant oil or engine oil, thereby reducing costs.

[0069] Reference Figure 3 and Figure 4 As shown, in some embodiments, a pressure equalizing hole 43 is provided on the outer wall of the outlet pipe 4 , so that the air pressure between the inner cavity of the outlet pipe 4 and the external separation cavity 13 or the outlet cavity 17 can be balanced.

[0070] Reference Figure 1 , Figure 3 and Figure 4 As shown, in some embodiments, a first partition 5 is provided in the barrel 1 for separating the inner cavity of the barrel 1 into an upper area and a lower area located below the upper area; the separation chamber 13 is located in the upper area, and the liquid storage chamber 14 is located in the lower area.

[0071] That is to say, the first partition 5 is specifically arranged in a direction perpendicular to the axial direction of the cylinder 1, so that the inner cavity of the cylinder 1 can be divided into an upper area above and a lower area below. The upper area can be used to separate and form a separation chamber 13, and the lower area can be used to separate and form a liquid storage chamber 14. In this way, the liquid in the gas-liquid mixture can sink under the action of gravity and flow into the liquid storage chamber 14 in the lower area, while the gas will not enter the liquid storage chamber 14 due to its lower density, thereby realizing gas-liquid separation.

[0072] Reference Figure 3 and Figure 4 As shown, in some embodiments, at least two second partitions 6 are provided in the upper area, and the at least two second partitions 6 are arranged in sequence along the circumference of the cylinder 1 to separate the upper area into at least two separation chambers 13; the gas-liquid separation port 16 is provided on the second partition 6.

[0073] Exemplarily, the separation chamber 13 in this embodiment can be set to four, and in this case, the second partition 6 can be set to four, so that the upper area can be divided into four separation chambers 13, that is, the first separation chamber 131, the second separation chamber 132, the third separation chamber 133 and the fourth separation chamber 134 of the four separation chambers 13 are arranged in sequence along the flow direction of the gas-liquid mixture, and the second partition 6 between the first separation chamber 131 and the second separation chamber 132 is provided with a gas-liquid separation port 16, and the second partition 6 between the second separation chamber 132 and the fourth separation chamber 13 is provided with a gas-liquid separation port 16. A gas-liquid separation port 16 is provided, and a gas-liquid separation port 16 is provided on the second partition 6 between the third separation chamber 133 and the fourth separation chamber 134, while a gas-liquid separation port 16 is not provided on the second partition 6 between the fourth separation chamber 134 and the first separation chamber 131, so that the gas-liquid mixture can be separated into gas and liquid after passing through the first separation chamber 131, the second separation chamber 132, the third separation chamber 133 and the fourth separation chamber 134 in sequence, and the separated gas is discharged through the outlet 12, and the separated liquid enters the liquid storage chamber 14 below the separation chamber 13.

[0074] For example, in other implementations, the separation chambers 13 may also be set to two, three or more than four, and the corresponding second partitions 6 may be set according to the number of separation chambers 13 actually required, which is not specifically limited in this embodiment.

[0075] Reference Figure 3 and Figure 4 As shown, in some embodiments, the angle between the two second partitions 6 corresponding to each separation chamber 13 on the upstream side of the separation chamber 13 on the most downstream side is greater than 100°; and / or the angle between the two second partitions 6 corresponding to the separation chamber 13 on the most downstream side is in the range of 0°-50°.

[0076] In specific implementation, the angle between the two second partitions 6 corresponding to all separation chambers 13 except the separation chamber 13 on the most downstream side can be set to be greater than 100°, so that the volume of each separation chamber 13 except the separation chamber 13 on the most downstream side is larger, so as to increase the flow path of the gas-liquid mixture when it flows through the separation chamber 13, so as to improve the gas-liquid separation effect. In addition, the volume of each separation chamber 13 except the separation chamber 13 on the most downstream side can be set to be consistent, that is, the angle between the two second partitions 6 enclosing each separation chamber 13 can be consistent.

[0077] Exemplarily, the angle between the two second partitions 6 corresponding to each separation chamber 13 on the upstream side of the separation chamber 13 on the most downstream side can be 105°, or can be 110° or can be 115°. In specific implementation, the angle between the two second partitions 6 enclosing the liquid storage chamber 14 on the most downstream side ranges from 0° to 50°, so that the volume of the separation chamber 13 on the most downstream side is smaller, thereby providing a larger volume to other separation chambers 13, so that other separation chambers 13 on the upstream side can effectively separate the gas-liquid mixture.

[0078] Exemplarily, the angle between the two second partitions 6 corresponding to the separation chamber 13 on the most downstream side may be 10°, or 15°, or 20°.

[0079] In some embodiments, the first partition 5 and each second partition 6 are integrally formed, thereby improving the integration of parts, saving manufacturing steps, and improving structural strength.

[0080] Furthermore, the liquid blocking member 2 and the second partition 6 are integrally formed, thereby saving manufacturing steps and improving the structural strength of the second partition 6 .

[0081] Reference Figure 3 and Figure 4 As shown, in some embodiments, there are at least two liquid storage chambers 14, and the at least two liquid storage chambers 14 are arranged in sequence along the circumference of the cylinder 1, and an air outlet chamber 17 connected to the separation chamber 13 on the most downstream side is also provided below the separation chamber 13 on the most downstream side; at least three third partitions 7 are provided in the lower area to separate the lower area into the air outlet chamber 17 and at least two liquid storage chambers 14.

[0082] Exemplarily, the first partition 5, the second partition 6 and the third partition 7 can be integrally formed into a complete partition structure, thereby improving the integration, saving manufacturing steps and improving the structural strength.

[0083] Exemplarily, the liquid storage chamber 14 in this embodiment can be set to three, and the third partition 7 can be set to four, so that the lower area can be divided into three liquid storage chambers 14 and one air outlet chamber 17, that is, the first liquid storage chamber, the second liquid storage chamber, the third liquid storage chamber and the air outlet chamber 17 of the three liquid storage chambers 14 are arranged in sequence along the flow direction of the gas-liquid mixture, and the third partition 7 between the first liquid storage chamber and the second liquid storage chamber is provided with a liquid through hole 44, and the third partition 7 between the second liquid storage chamber and the third liquid storage chamber is provided with a liquid through hole 44, while the third partition 7 between the air outlet chamber 17 and the first liquid storage chamber 14 is not provided with a liquid through hole 44, so that the third liquid storage chamber and the air outlet chamber 17 are not connected, so that the liquid entering each liquid storage chamber 14 can circulate between different liquid storage chambers 14, so that the liquid level of the liquid in each liquid storage chamber 14 is the same, and the liquid in a certain liquid storage chamber 14 is avoided. The situation of overfilling.

[0084] For example, in other implementations, the liquid storage chamber 14 may also be set to two, three or more than four, and the corresponding third partition 7 may be set according to the number of liquid storage chambers 14 actually required, which is not specifically limited in this embodiment.

[0085] For example, there may be at least two liquid holes 44 disposed on the third partition 7, and the at least two liquid holes 44 are spaced apart in the height direction, so as to be suitable for the flow of liquids at different liquid levels in different liquid storage chambers 14. Figure 3 As shown, the number of liquid through holes 44 on each third separator 7 can be three, or can also be 1, 2, 4 or more.

[0086] Reference Figure 3 and Figure 4 As shown, in some embodiments, among all the liquid storage chambers 14, at least one liquid storage chamber 14 is provided with a molecular sieve 3, so that the liquid entering the liquid storage chamber 14 can be dried by the molecular sieve 3, so that under certain working conditions, the liquid can be converted into gas and then returned to the corresponding separation chamber 13 through the liquid hole 15, so as to reduce the moisture contained in the refrigerant in the liquid storage chamber 14, thereby preventing the occurrence of ice blockage.

[0087] Exemplarily, a molecular sieve 3 may be provided in the liquid storage chamber 14 on the downstream side, so that the liquid entering the liquid storage chamber 14 on the downstream side can be dried by the molecular sieve 3, so that under certain working conditions, the liquid can be converted into gas and then returned to the corresponding separation chamber 13 through the liquid hole 15, so as to reduce the moisture contained in the refrigerant in the liquid storage chamber 14, thereby preventing the occurrence of ice blockage.

[0088] In addition, the molecular sieve 3 can be fixed in the liquid storage chamber 14 by a cable tie 31 or can also be bonded in the liquid storage chamber 14 .

[0089] Reference Figure 1 , Figure 3 and Figure 4 As shown, in some embodiments, the gas-liquid separator also includes an air intake pipe 8, which is located in the separation chamber 13 on the most upstream side, and one end of the air intake pipe 8 is connected to the inlet 11, and the other end of the air intake pipe 8 is connected to the separation chamber 13 on the most upstream side, so as to facilitate the external gas-liquid mixture to be separated to enter the air intake pipe 8 through the inlet 11 and then enter the separation chamber 13 on the most upstream side to realize subsequent separation operations.

[0090] Reference Figure 1 and Figure 2 As shown, in some embodiments, the cylinder 1 includes a cylinder body 191 and a top cover 192 detachably covered on the top of the cylinder body 191 , and the inlet 11 and the outlet 12 are both arranged on the top cover 192 .

[0091] In a specific implementation, after the barrel body 191 and the top cover 192 are jointly enclosed to form a chamber, the first partition 5, the second partition 6 and the third partition 7 can be used to separate and form corresponding cavities.

[0092] In addition, the height from the first partition 5 to the bottom surface of the barrel body 191 needs to be greater than 60% of the height from the top cover 192 to the bottom surface of the barrel body 191 to meet the liquid storage requirements.

[0093] Exemplarily, the first partition 5, the second partition 6 and the third partition 7 can all be partitions. In addition, the third partition 7 can divide the liquid into small volumes, and the first partition 5 can effectively isolate the upper gaseous area from the lower liquid area, which is conducive to keeping the dryness of the gas discharged through the outlet 12 stable in various driving scenarios.
