[0001] The present application relates to the field of liquid separation technology, and in particular to a liquid separator. Background Art

[0002] Liquid separators are often installed in air conditioning systems, primarily to thoroughly mix the gas-liquid refrigerant and evenly distribute it. However, traditional liquid separator structures struggle to achieve sufficient mixing within the separator, leading to uneven refrigerant distribution and, consequently, compromising the cooling efficiency of the entire air conditioning system. Utility Model Content

[0003] Based on this, it is necessary to provide a liquid separator to solve the problem that the refrigerant in the existing liquid separator structure is unevenly mixed, resulting in poor refrigeration effect.

[0004] The present application provides a liquid separator, which includes a main body, wherein the main body is provided with a liquid inlet hole and multiple liquid separation holes, each of the liquid separation holes includes a spiral section, and the spiral section is arranged at one end of the liquid separation hole close to the liquid inlet hole and is connected to the liquid inlet hole; wherein, the spiral section extends in a spiral shape in a direction away from the liquid inlet hole.

[0005] In one embodiment, the axis of the spiral segment is defined as a helix, and the axis around which the helix is defined as a first axis. The inner diameter of the spiral segment is D, the pitch of the helix is P, and the straight-line distance between the ends of the helix along the first axis is L. D, P, and L satisfy the conditions 1 / 6 ≤ L / P ≤ 1, and 2 ≤ P / D ≤ 8. It is understood that this configuration effectively balances the difficulty of machining the separation hole and the uniformity of refrigerant separation.

[0006] In one embodiment, two adjacent spiral segments are at least partially interconnected in the circumferential direction of the main body, so that the projections of the plurality of spiral segments on a plane perpendicular to the axis of the main body form a spiral radial shape. It is understood that such an arrangement simplifies the processing of the spiral segments.

[0007] In one embodiment, the liquid separation hole further comprises a straight segment, one end of which is connected to and communicates with the spiral segment, and the other end of which forms the outlet of the liquid separation hole; wherein the axis of the straight segment extends in a straight line. It is understood that such a configuration can further reduce the difficulty of processing the liquid separation hole.

[0008] In one embodiment, the axis of the straight segment is defined as a second axis. The second axis and the axis of the main body are coplanar, and the angles A and A between the second axis and the axis of the main body satisfy 10°≤A≤60°. It will be appreciated that this arrangement facilitates the positioning and processing of the straight segment.

[0009] In one embodiment, the axis of the straight segment is defined as a second axis. The second axis and the axis of the main body are located in different planes, and the angle B between the second axis and the axis of the main body satisfies 15°≤B≤18°. It is understood that this configuration can further improve the uniformity of refrigerant separation.

[0010] In one embodiment, the main body further defines a jet hole, located between the liquid inlet and the liquid separation hole, with one end of the jet hole communicating with the liquid inlet and the other end communicating with the spiral segment of the liquid separation hole. The inner diameter of at least some of the jet holes is smaller than that of the liquid inlet. This arrangement is understood to improve the refrigerant flow rate, thereby enhancing refrigerant uniformity.

[0011] In one embodiment, a weight-reducing groove is defined at one end of the main body away from the liquid inlet, the weight-reducing groove being spaced apart from the liquid separation hole, and a plurality of liquid separation holes being disposed around the periphery of the weight-reducing groove and not in communication with the weight-reducing groove. It is understood that such a configuration can reduce the weight of the liquid dispenser and reduce material usage, thereby significantly lowering the material cost of the liquid dispenser.

[0012] In one embodiment, the liquid separation hole further comprises a straight segment, one end of which is connected to and communicates with the spiral segment, and the other end of which forms the outlet of the liquid separation hole. The distance from the axis of the straight segment to the outer wall of the main body is equal to the distance from the axis of the straight segment to the inner wall of the weight loss groove. It is understood that this arrangement improves the welding effect between the liquid separator and the outlet pipe.

[0013] In one embodiment, the liquid distributor further includes a throttle ring, wherein a positioning portion is provided at one end of the liquid inlet hole adjacent to the liquid separation hole, and the throttle ring abuts against the positioning portion; wherein a throttle hole is formed on the throttle ring, and the two ends of the throttle hole are respectively connected to the liquid inlet hole and the liquid separation hole. It is understood that such a configuration can improve the installation stability of the throttle ring.

[0014] Compared with the prior art, the liquid separator provided in the present application forms the spiral segment structure of the present application by setting a partial hole section of the liquid separation hole close to one end of the liquid inlet hole as a spirally extended structure. In this way, the spiral segment can realize spiral drainage of the refrigerant. When the refrigerant in a gas-liquid mixed state flows from the liquid separation hole to the inlet end of multiple liquid inlet holes, during the distribution process of the refrigerant, sufficient turbulence of the refrigerant can be simultaneously achieved, thereby effectively improving the mixing uniformity and distribution uniformity of the refrigerant.

[0029] Liquid separators are often installed in air conditioning systems, primarily to thoroughly mix the gas-liquid refrigerant and evenly distribute it. However, traditional liquid separator structures struggle to achieve sufficient mixing within the separator, leading to uneven refrigerant distribution and, consequently, compromising the cooling efficiency of the entire air conditioning system.

[0030] See also Figures 1-4To address the problem of uneven refrigerant mixing in existing liquid separator structures, resulting in poor cooling performance, the present application provides a liquid separator 100. The liquid separator 100 includes a main body 10 having a liquid inlet 101 and a plurality of liquid separation holes 102. Each liquid separation hole 102 includes a spiral segment 1021, which is located at one end of the liquid separation hole 102 near the liquid inlet 101 and communicates with the liquid inlet 101. The spiral segment 1021 extends in a spiral shape away from the liquid inlet 101.

[0031] The present application forms the spiral segment 1021 structure of the present application by setting a partial hole section of the liquid separation hole 102 close to one end of the liquid inlet hole 101 as a spirally extended structure. In this way, the spiral segment 1021 can realize the spiral drainage of the refrigerant. When the refrigerant in a gas-liquid mixed state flows from the liquid separation hole 102 to the inlet ends of multiple liquid inlet holes 101, during the distribution process of the refrigerant, sufficient turbulence of the refrigerant can be simultaneously achieved, thereby effectively improving the mixing uniformity and distribution uniformity of the refrigerant.

[0032] Furthermore, the spiral segment 1021 can be formed by offsetting the machining center hole of a machining tool (usually a drill bit) from the rotation center of the workpiece by 0.1 mm to 1 mm. Here, the offset distance can be 0.1 mm, 0.3 mm, 0.5 mm, 0.7 mm, or 1 mm, etc., and can be reasonably set according to actual needs. Of course, other methods can also be used for forming.

[0033] It is understood that the liquid dispenser 100 of the present application can be formed without changing the existing production process or adding processing steps during processing. It only needs to adjust the offset distance of the drill bit when processing the liquid separation hole 102. In this way, the production cost of the liquid dispenser 100 is effectively reduced while ensuring the performance of the liquid dispenser 100.

[0034] In one embodiment, if Figure 6 As shown, the axis of the helical segment 1021 is defined as a helix, and the axis around which the helix revolves is the first axis. The inner diameter of the helical segment 1021 is D, and the pitch of the helix is P. D and P satisfy 2≤P / D≤8. This results in a reasonable helix pitch and facilitates machining.

[0035] Optionally, the value of P / D can be 2, 3, 4, 5, 6, 7 or 8, etc., which are not listed here one by one.

[0036] It should be noted that the axis around which the helix revolves is the axis of the cylinder on which the helix is located.

[0037] Furthermore, the straight-line distance between the two ends of the spiral along the first axis is L, and P and L satisfy 1 / 6 ≤ L / P ≤ 1. Thus, by properly setting the rotation angle of the axis of the spiral segment 1021, the difficulty of machining the liquid separation hole 102 and the uniform liquid separation effect on the refrigerant can be effectively balanced.

[0038] Specifically, when L / P>1, the spiral length of the spiral line is longer, which increases the processing difficulty of the spiral segment 1021. When L / P<1 / 6, the spiral length of the spiral line is shorter, and the refrigerant is not fully mixed before distribution, which will reduce the cooling effect of the refrigerant.

[0039] As a preferred solution, the present application can set L / P = 1 / 2, that is, the spiral line rotates 90 degrees from the starting end to the end. However, this is not limited to this. In other embodiments, L / P can also be 1 / 6, 1 / 3, 2 / 3, 5 / 6, or 1, etc., which are not listed here one by one.

[0040] In order to further reduce the difficulty of processing the spiral segment 1021, in one embodiment, as shown in FIG. Figure 3 As shown, two adjacent spiral segments 1021 are at least partially interconnected in the circumferential direction of the main body 10, so that the projections of the multiple spiral segments 1021 on a plane perpendicular to the axis of the main body 10 form a spiral radial shape. In other words, the spiral segments 1021 eliminate part of the sidewall along the circumference of the main body 10, making the processing of the multiple spiral segments 1021 simpler and further enhancing the turbulence effect on the refrigerant.

[0041] In one embodiment, if Figures 1-4 As shown, the liquid separation hole 102 further includes a straight segment 1022. One end of the straight segment 1022 is connected to and communicates with the spiral segment 1021, and the other end forms the outlet of the liquid separation hole 102 and is used to connect to the outlet pipe. The axis of the straight segment 1022 extends in a straight line. As such, the straight segment 1022 in the form of a straight hole is easy to machine, further reducing the difficulty of machining the liquid separation hole 102.

[0042] Furthermore, in one embodiment, Figure 4 As shown, the axis of the straight segment 1022 is defined as the second axis. The second axis and the axis of the main body 10 are in the same plane, and the angle A between the second axis and the axis of the main body 10 satisfies 10°≤A≤60°. This facilitates the positioning and processing of the straight segment 1022.

[0043] For example, the angle A between the second axis and the axis of the main body 10 in this embodiment can be 10°, 20°, 30°, 40°, 50° or 60°, etc., which are not listed here one by one.

[0044] In another embodiment, if Figure 5As shown, the second axis and the axis of the main body 10 are in different planes, and the angles B and B between the second axis and the axis of the main body 10 satisfy 15°≤B≤18°. This makes the transition between the straight segment 1022 and the spiral segment 1021 smoother, further improving the uniformity of refrigerant separation.

[0045] For example, the angle A between the second axis and the axis of the main body 10 in this embodiment can be 15°, 16°, 17° or 18°, etc., which are not listed here one by one.

[0046] In one embodiment, if Figure 2 As shown, the main body 10 is further provided with a jet hole 103, which is located between the liquid inlet hole 101 and the liquid separation hole 102. One end of the jet hole 103 is connected to the liquid inlet hole 101, and the other end is connected to the spiral section 1021 of the liquid separation hole 102. The inner diameter of at least some of the jet holes 103 is smaller than that of the liquid inlet hole 101. The provision of the jet holes 103 helps to increase the flow rate of the refrigerant, thereby improving the mixing and distribution of the refrigerant and enhancing the uniformity of the refrigerant.

[0047] The liquid distributor 100 with the jet hole 103 is mainly used in split-type cabinet air conditioners.

[0048] In another embodiment, if Figure 1 As shown, the main body 10 may not have the jet hole 103, thereby reducing the number of processing steps and increasing the processing speed. In this case, the liquid dispenser 100 is mainly used in household split-type air conditioners.

[0049] In order to reduce the manufacturing cost of the liquid dispenser 100, in one embodiment, the liquid dispenser 100 is preferably configured as an aluminum part. Of course, in other embodiments, the liquid dispenser 100 can also be configured as a copper part, etc.

[0050] In one embodiment, if Figure 4 As shown, a weight-reducing groove 104 is provided at one end of the main body 10, away from the liquid inlet 101. The weight-reducing groove 104 is spaced apart from the liquid separation hole 102. The plurality of liquid separation holes 102 are arranged around the periphery of the weight-reducing groove 104 and are not connected to the weight-reducing groove 104. Thus, the weight-reducing groove 104 can reduce the weight of the liquid dispenser 100 and reduce material usage, thereby significantly reducing the material cost of the liquid dispenser 100.

[0051] Furthermore, in one embodiment, the distance from the axis of the straight segment 1022 to the outer wall of the main body 10 is equal to the distance from the axis of the straight segment 1022 to the inner wall of the weight-reducing groove 104. Since the end of the straight segment 1022 away from the spiral segment 1021 is used for welding to the outlet pipe, by making the distance from the axis of the straight segment 1022 to the outer wall of the main body 10 and the distance from the axis of the straight segment 1022 to the inner wall of the weight-reducing groove 104 equal, the thickness of the straight segment 1022 on both sides of the radial direction can be maintained consistent, which facilitates uniform heating during welding, thereby improving the welding effect between the liquid dispenser 100 and the outlet pipe.

[0052] In one embodiment, if Figure 1-Figure 5 As shown, the liquid separator 100 also includes a throttle ring 20. A positioning portion 11 is provided at one end of the liquid inlet 101 near the liquid separation hole 102, and the throttle ring 20 abuts against the positioning portion 11. A throttle hole 201 is provided on the throttle ring 20, and the two ends of the throttle hole 201 are respectively connected to the liquid inlet 101 and the liquid separation hole 102. In this way, the positioning portion 11 can achieve the positioning of the throttle ring 20, thereby improving the installation stability of the throttle ring 20 and preventing the throttle ring 20 from falling off. The throttle ring 20 can increase the flow rate of the refrigerant and cause turbulence in the refrigerant, thereby making the distribution of the refrigerant more uniform.

[0053] Specifically, the positioning portion 11 may be as follows Figure 1 、 Figure 4 and Figure 5 As shown, the positioning portion 11 is formed by the inner wall of the liquid inlet hole 101 protruding toward the axial direction. Alternatively, the positioning portion 11 can be as Figure 2 As shown, it is formed by the tapered inner wall at the connection between the jet hole 103 and the liquid inlet hole 101.

[0054] Generally, household split air conditioners and split cabinet air conditioners require a smaller refrigerant flow rate, so the volume of the liquid separator 100 is also smaller, and the number of liquid separation holes 102 on the liquid separator 100 is also smaller. Figure 3 and Figure 4 As shown, its volume is larger and the number of liquid separation holes 102 is also larger.

[0055] The present application sets the spiral section 1021 on the liquid separation hole 102 to extend in a spiral shape, which can be applied to different liquid separators 100, so that different types of liquid separators 100 can achieve good liquid separation effects when applied to different air-conditioning systems such as household split air conditioners, split cabinet air conditioners and commercial unit air conditioners, thereby greatly improving the uniformity of the refrigerant and enabling different air-conditioning systems to have good cooling effects.

[0056] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of patent protection for the present application shall be determined by the appended claims.
