[0032] Liquid distributors are usually installed in refrigeration systems to evenly distribute the medium, thereby improving the refrigeration effect of the refrigeration system.

[0033] The existing liquid separator includes a tube body and a capillary arranged at one end of the tube body. There are multiple capillaries to evenly separate the medium entering the tube body. Some liquid separators also install a throttling ring at the inlet of the tube body to improve the separation effect. The throttling ring is fixed by a clamping ring. The setting of the clamping ring makes the structure of the liquid separator complicated.

[0034] For this, see Figure 1-Figure 4The utility model provides a liquid dispenser 100, which includes a tube body 10 and a throttling device 20. One end of the tube body 10 is an inlet 11, and the other end is an outlet 12. The throttling device 20 is installed in the tube body 10 and is located between the inlet 11 and the outlet 12. A through throttling hole 21 is opened on the throttling device 20, and the throttling hole 21 connects the inlet 11 and the outlet 12. The liquid dispenser 100 also includes a capillary 30. The capillary 30 is a plurality of capillaries, which are arranged at one end of the tube body 10 close to the outlet 12, connected to the inner wall of the tube body 10, and connected to the inlet 11. At least one of the tube body 10 and the throttling device 20 is provided with a positioning portion 22, and the tube body 10 and the throttling device 20 are limited by the positioning portion 22. In this way, the throttle 20 is installed between the inlet 11 and the outlet 12. After the medium enters the tube body 10, it will be throttled by the throttle 20, and the multiple throttle holes 21 on the throttle 20 can disturb the medium, so that the medium is mixed more evenly and is separated through multiple capillaries 30. At least one of the tube body 10 and the throttle 20 is provided with a positioning portion 22, so that the two can be positioned and connected with each other, thereby preventing the throttle 20 from falling off the tube body 10. The positioning portion 22 enables the throttle 20 to be stably limited with the tube body 10, without the need to add additional structures such as welding clamps, thereby simplifying the structure of the liquid distributor 100 and reducing production costs.

[0035] In this embodiment, a plurality of throttling holes 21 are provided, and the plurality of throttling holes 21 are arranged at intervals to increase the flow velocity of the medium, so that the medium forms a jetting effect, thereby improving the throttling efficiency of the throttling member 20 .

[0036] Specifically, a chamfer 24 is formed on the outer peripheral edge of one end of the throttling member 20 facing the inlet 11 . The chamfer 24 can make the flow of the medium smoother and reduce the interference generated during the connection and assembly process of the throttling member 20 with the inner wall of the tube body 10 .

[0037] The throttle holes 21 are evenly spaced along the circumference of the throttle member 20 to form a honeycomb-like arrangement structure.

[0038] Along the axial direction of the tube body 10, the throttling piece 20 has a connecting section 25 connected to the inner wall of the tube body 10. Along the radial direction of the tube body 10, the throttling piece 20 has a throttling section 26 with a throttling hole 21. The connecting section 25 is connected to the throttling section 26. The connecting section 25 extends along the axial direction of the tube body 10 and is used for connecting the throttling piece 20 and the tube body 10 to increase the connection area between the throttling piece 20 and the tube body 10. The throttling section 26 is arranged along the radial direction of the tube body 10, so that the throttling hole 21 has a better throttling effect on the medium.

[0039] Along the axial direction of the tube body 10, the length of the connecting section 25 is L, and the range of L satisfies: 3mm≤L≤8mm. In this way, it is ensured that the length of the connecting section 25 is long enough and has enough contact area with the inner wall of the tube body 10, thereby ensuring the installation stability of the throttle 20. It also prevents the throttle 20 from being too long, which increases the difficulty of installation, affects the layout of other components inside the tube body 10, and increases consumables.

[0040] Exemplarily, the value of L can be 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, etc., as long as it is between 3mm and 8mm, and is not limited to the two end values.

[0041] Furthermore, the wall thickness of the throttling member 20 is D, and the range of D satisfies: 0.2mm≤D≤2mm. In this way, it is ensured that the wall thickness of the throttling member 20 is not too thin to affect its structural strength and prevent it from deforming under the long-term scouring of the medium, and it is also prevented from being too thick to affect its throttling effect.

[0042] Exemplarily, the value of H can be 0.2mm, 0.4mm, 0.6mm, 0.8mm, 1mm, 1.2mm, 1.4mm, 1.6mm, 1.8mm, 2mm, etc. It only needs to be between 0.2mm and 2mm, and is not limited to the two end values.

[0043] There are many implementation methods for disposing the positioning portion 22 , and two embodiments thereof are listed and described in detail herein.

[0044] Embodiment 1

[0045] See also Figure 2 The inner wall of the tube body 10 is radially inwardly protruded with a limit assembly 13, and the two limit assemblies 13 are positioning parts 22. The limit assembly 13 is the positioning part 22. There are multiple limit assemblies 13, and at least two limit assemblies 13 are close to the side of the throttling member 20 and respectively abut against the two ends of the throttling member 20 in the axial direction. In this way, since the flow direction of the medium is from the inlet 11 to the outlet 12, that is, it flows along the axial direction of the tube body 10, the limit assembly 13 abuts against the two ends of the throttling member 20 in the axial direction, and its limiting effect on the throttling member 20 is relatively stable. Furthermore, the cross section of the limit assembly 13 is an arc shape, so there is no edge on the limit assembly 13, which avoids collision and wear between the limit assembly 13 and the throttling member 20, is more durable, and is also convenient for processing and forming. In other embodiments, the cross-section of the limiting component 13 can also be set to a rectangle, that is, the abutting surface between the limiting component 13 and the throttling member 20 is a plane, the abutment between the limiting component 13 and the throttling member 20 is tighter, and the limiting effect is better.

[0046] Preferably, the limiting assembly 13 is formed by stamping the tube body 10 , which has a simple process and saves costs.

[0047] In this embodiment, a plurality of limit assemblies 13 are evenly spaced along the circumference of the tube body 10 so as to stably abut against the throttling member 20. In other embodiments, the limit assemblies 13 may also be configured as an annular protrusion structure, and the annular limit assemblies 13 may form a circumferential abutment with the throttling member 20.

[0048] Embodiment 2

[0049] See also Figure 7-Figure 8 , the inner wall of the tube body 10 is radially inwardly provided with a plurality of positioning protrusions 14, and the outer peripheral wall of the throttle 20 is provided with a positioning groove 23, and each positioning protrusion 14 is correspondingly embedded in a positioning groove 23. Alternatively, the outer peripheral wall of the throttle 20 is radially outwardly provided with a plurality of positioning protrusions 14, and the inner wall of the tube body 10 is provided with a plurality of positioning grooves 23, and each positioning protrusion 14 is correspondingly embedded in a positioning groove 23. The positioning protrusion 14 and the positioning groove 23 are the positioning portion 22. In this way, the positioning protrusion 14 is embedded in the positioning groove 23, and the outer peripheral side of the positioning protrusion 14 and the groove wall of the positioning groove 23 form a circumferential limit, and the limiting effect is better. Multiple positioning protrusions 14 and multiple positioning grooves 23 can form multiple limiting points, further improving the installation stability of the throttle 20.

[0050] In this embodiment, the positioning protrusions 14 are arranged on the inner wall of the tube body 10, and the positioning grooves 23 are opened on the outer peripheral wall of the throttle 20. Taking this as an example, the positioning protrusions 14 are evenly spaced along the circumference of the inner wall of the tube body 10, and correspondingly, the positioning grooves 23 are evenly spaced along the circumference of the outer peripheral wall of the throttle 20. Each positioning protrusion 14 is correspondingly embedded in a positioning groove 23, and both are arranged in the circumferential direction, so that the limiting effect between the positioning member and the tube body 10 is more balanced and stable.

[0051] Of course, in other embodiments, when the positioning protrusion 14 is protruding from the outer peripheral wall of the throttling member 20 and the positioning groove 23 is opened on the inner wall of the tube body 10, the two can still be arranged along the circumferential direction as above, thereby forming a uniform and stable limiting effect.

[0052] Preferably, the positioning protrusion 14 is formed by stamping the tube body 10 or the throttle member 20 , which simplifies the process and saves costs.

[0053] Along the radial direction of the tube body 10, the depth of the positioning groove 23 is H, and the range of H satisfies: 0.2mm≤H≤1.5mm. In this way, it is ensured that the depth of the positioning groove 23 is sufficient to produce a limiting fit with the positioning protrusion 14, thereby preventing the positioning protrusion 14 from falling out of the positioning groove 23 and causing the throttle 20 to fall off, and it is also prevented that the positioning groove 23 is too deep, resulting in insufficient structural strength of the throttle 20, causing the throttle 20 to be damaged.

[0054] Exemplarily, the value of H can be 0.2mm, 0.4mm, 0.6mm, 0.8mm, 1.0mm, 1.2mm, 1.4mm, etc. It only needs to be between the two end values ​​and can be flexibly changed according to needs.

[0055] Preferably, the positioning protrusion 14 is a hemispherical structure, and the notch of the positioning groove 23 is circular, so that the two are more adaptable, and when the throttling member 20 is axially offset, the positioning protrusion 14 and the positioning groove 23 can still match together.

[0056] Compared with the prior art, the utility model installs the throttle 20 between the inlet 11 and the outlet 12. After the medium enters the tube body 10, it will be throttled by the throttle 20 to increase the flow rate, and the multiple throttle holes 21 on the throttle 20 can disturb the medium, so that the medium is mixed more evenly and is separated through multiple capillaries 30. At least one of the tube body 10 and the throttle 20 is provided with a positioning portion 22, so that the two can be positioned and connected with each other, thereby preventing the throttle 20 from falling off the tube body 10.

[0057] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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.

[0058] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
