Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of air conditioners, in particular to a liquid distributor. BACKGROUND

[0002] In an air conditioning system, the refrigerant after throttling through an expansion valve is in a gas-liquid two-phase coexistence state. Due to the different properties of gas-liquid two-phase such as dynamic viscosity and surface tension, under the influence of external factors such as gravity and forced vibration of pipeline, a mixed inhomogeneous flow pattern is formed in the pipeline. The two-phase refrigerant enters the evaporator after being distributed by the liquid distributor. However, the mixing and distribution uniformity of the current liquid distributor is limited, which leads to uneven distribution of the refrigerant entering the evaporator through the liquid distributor, resulting in low heat exchange efficiency of the evaporator, and further reducing the energy efficiency of the entire air conditioning system.

[0008] In one of the embodiments, the size of the flow passage is a, the maximum size of the flow disturbing structure is b, and 0.04b≤a≤0.3b along the radial direction of the distributor pipe.

DETAILED DESCRIPTION

[0021] To make the above objectives, features and advantages of the present application more clear and easily understood, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.

Therefore, the specific embodiments disclosed below are not intended to limit the scope of the present application.

Thus, a feature with a "first", "second" designation can include at least one of the features, explicitly or implicitly. In the description of the present application, the meaning of "a plurality of" is at least two, such as two, three, etc., unless otherwise explicitly specified and limited.

[0024] In the present application, unless otherwise explicitly specified and limited, the "on", "under", "above" and "over" of a first feature to a second feature can be that the first feature is in direct contact with the second feature, or the first feature is indirectly in contact with the second feature through an intermediate medium.

[0025] Unless otherwise defined, all technical and scientific terms used in the application's specification have the same meaning as commonly understood by one of ordinary skill in the art to which the application belongs. The terminology used in the application's specification is for describing particular embodiments only and is not intended to be limiting of the application. The use of the terms "and / or" includes a combination of one or more of the associated listed items.

[0026] Referring to Figures 1 to 4 The application provides a distributor 100, which comprises a distributor pipe 10, the distributor pipe 10 is provided with an inlet 101 at one end along the axial direction of the distributor pipe 10 and a distributor part 11 at the other end, the distributor part 11 is provided with a plurality of distributor holes 111 arranged at intervals, and the distributor pipe 10 is provided with a distributor cavity 102 connected between the inlet 101 and the plurality of distributor holes 111. In this way, the fluid flows into the distributor cavity 102 from the inlet 101 of the distributor pipe 10, then flows from the distributor cavity 102 to the distributor holes 111, and finally flows out from the plurality of distributor holes 111, thereby achieving the distribution of the fluid.

[0027] Further, the distributor 100 further comprises a turbulence structure 20, which is arranged in the distributor cavity 102 and connected to the distributor part 11, so as to realize the turbulence of the fluid and promote the full mixing of the gas-liquid two-phase fluid.

[0028] Specifically, the turbulence structure 20 is provided with a flow guide part 21, which is arranged tapered from the distributor part 11 towards the inlet 101 along the axial direction of the distributor pipe 10, so as to form an inclined flow guide surface, which is beneficial to guide the fluid to flow along the inclined flow guide surface and promote the flow of the fluid from the inlet 101 to the distributor part 11.

[0029] Further, the flow guide part 21 is provided with a plurality of flow-through openings 211 arranged at intervals, each flow-through opening 211 is arranged extending, each flow-through opening 211 is connected between the distributor cavity 102 and the plurality of distributor holes 111, and the flow-through opening 211 is provided with a turbulence member 22. In this way, when the fluid flows along the surface of the flow guide part 21, it can flow out from the flow-through opening 211 to the distributor hole 111, wherein the turbulence member 22 at the flow-through opening 211 can form turbulence to the fluid, promote the mixing of the gas-liquid two-phase fluid, and promote the uniform distribution of the fluid in the distributor hole 111.

[0030] In summary, by arranging the turbulence structure 20, the flow of the fluid can be guided by the flow guide part 21, and at the same time, the turbulence member 22 at the flow-through opening 211 can disturb the fluid, promote the mixing of the gas-liquid two-phase fluid, and make the fluid evenly distributed from the plurality of distributor holes 111.

[0031] As Figure 1As shown, in a specific embodiment, the angle between the guide section 21 and the axis of the distributor 10 is β, where 45°≤β≤75°. This forms a sufficiently inclined guide surface to direct fluid flow while avoiding an excessively large inclination angle that would result in an overly short axial dimension of the turbulence-inducing structure 20, thus minimizing the turbulence-inducing effect of the turbulence-inducing element 22 and ensuring effective fluid turbulence. For example, β = 45°, 60°, or 75°.

[0032] like Figures 1 to 4 As shown, in an optional embodiment, multiple flow ports 211 are spaced apart along the circumference of the turbulence structure 20, so that fluid can flow out through the flow ports 211 along the circumference of the turbulence structure 20. Each flow port 211 extends along the tapering direction of the guide portion 21. Along the tapering direction of the guide portion 21, each flow port 211 is provided with multiple spaced turbulence elements 22, which promotes sufficient turbulence of the fluid in the flow port 211 along the tapering direction of the guide portion 21, and promotes uniform mixing of the gas and liquid two-phase fluid.

[0033] like Figure 3 As shown, in a further embodiment, the dimensions of the flow port 211 along the circumferential direction of the turbulence structure 20 remain unchanged along the axis of the distribution pipe 10, facilitating direct processing and molding. For example, the shape of the flow port 211 is set to rectangular.

[0034] like Figure 4 As shown, in another embodiment, along the axis of the distribution pipe 10, the flow port 211 gradually narrows in size from the distribution section 11 toward the inlet 101 along the circumferential direction of the turbulence structure 20. This arrangement results in a larger flow port 211 near the distribution section 11 and a smaller flow port 211 near the inlet 101, accommodating the gradual narrowing of the guide section 21 from the distribution section 11 toward the inlet 101. This fully utilizes the surface area of ​​the guide section 21, allowing the flow port 211 to gradually enlarge as the fluid flows from the inlet 101 to the distribution hole 111, promoting smooth fluid flow. For example, the shape of the flow port 211 is trapezoidal or triangular.

[0035] like Figure 4 As shown, in a further embodiment, along the axis of the distribution pipe 10, the turbulence member 22 gradually narrows from the distribution section 11 toward the inlet 101 along the circumferential dimension of the turbulence structure 20. Thus, as the fluid flows from the inlet 101 toward the distribution section 11, the turbulence of the turbulence structure 20 gradually increases, and it can also adapt to the structure of the flow port 211 gradually narrowing from the distribution section 11 toward the inlet 101 along the circumferential dimension of the turbulence structure 20, so as to increase the turbulence while increasing the flowability.

[0036] like Figure 1 and Figure 3As shown, in a specific embodiment, the size of the flow port 211 along the radial direction of the distribution pipe 10 is 'a', and the maximum size of the turbulence-disrupting structure 20 is 'b', where 0.04b ≤ a ≤ 0.3b. This ensures that the flow port 211 has a sufficiently large diameter to facilitate fluid outflow while also guaranteeing the structural strength of the turbulence-disrupting structure 20. For example, a = 0.04b, 0.1b, or 0.3b.

[0037] like Figures 1 to 4 As shown, in a specific embodiment, the flow-dispersing element 22 is configured as a flow-dispersing plate, which is angled to the flow-guiding portion 21. This results in a simple structure for the flow-dispersing plate, making it easy to manufacture. The fluid flows along the guiding surface formed by the flow-guiding portion 21 into the flow port 211, and its flow direction changes under the disturbance of the flow-dispersing plate, causing turbulence and promoting thorough mixing of the gas-liquid two-phase fluid.

[0038] like Figure 1 As shown, in a specific embodiment, the angle between the baffle and the guide portion 21 is α, 45°≤α≤90°, so that the baffle can form an inclined baffle surface, promoting the flow of fluid along the baffle surface towards the distribution portion 11. At the same time, it also avoids the baffle from blocking most of the area of ​​the flow port 211, promoting sufficient flow. For example, α = 45°, 60° or 90°.

[0039] In a specific embodiment, at least the surface of the baffle facing the inlet 101 is provided with baffle protrusions, which the fluid needs to bypass, thereby further changing the fluid flow state and enhancing the baffle intensity; or, at least the surface of the baffle facing the inlet 101 is provided with baffle recesses, which the fluid flows into and out under the action of hydrodynamics, which can also enhance the baffle effect. Of course, the surface of the baffle facing the inlet 101 can also be provided with both baffle protrusions and baffle recesses to further intensify the baffle effect.

[0040] like Figures 1 to 4 As shown, in a specific embodiment, the top 23 of the turbulence structure 20 facing the inlet 101 is set as a spherical surface. The fluid flows into the liquid distribution chamber 102 from the inlet 101 and first contacts the top 23 of the turbulence structure 20. Therefore, the top 23 is set as a spherical surface to promote the flow of fluid along the smooth surface and promote the diversion of fluid from the top 23.

[0041] like Figures 1 to 4 As shown, furthermore, the surface formed by the flow guide 21 is set as a curved surface, and the smooth curved surface can enhance the flow guiding effect on the fluid. Specifically, the turbulence structure 20 can be set as a hollow cone shape, and the surface formed by the flow guide 21 is a conical surface.

[0042] like Figure 1 and Figure 2As shown in the specific embodiment, the liquid distribution pipe 10 is divided into an inlet section 12, an intermediate section 13 and an outlet section 14, the intermediate section 13 is connected between the inlet section 12 and the outlet section 14, the inlet section 12 is provided with an inlet 101, and the outlet section 14 is provided with a liquid distribution part 11. Along the axial direction of the liquid distribution pipe 10, the radial dimension of the intermediate section 13 gradually decreases from the outlet section 14 towards the inlet section 12, so as to cooperate with the gradually decreasing flow guide part 21 in the liquid distribution cavity 102 from the liquid distribution part 11 towards the inlet 101, thereby forming a narrow space between the flow guide part 21 and the inner wall of the intermediate section 13, the fluid flows into the space between the flow guide part 21 and the intermediate section 13 from the inlet 101, and the flow space of the fluid changes from wide to narrow, so as to promote the increase of the fluid flow rate, accelerate the flow of the fluid from the flow-through opening 211, and the disturbance of the fluid by the disturbance member 22 at the flow-through opening 211 intensifies the effect of fluid disturbance, and promotes the uniform mixing of the gas-liquid two-phase fluid.

[0043] As shown in the specific embodiment, Figure 1 In a further embodiment, the angle between the flow guide part 21 and the axis of the liquid distribution pipe 10 is greater than the angle between the pipe wall of the intermediate section 13 and the axis of the liquid distribution pipe 10. In this way, the space between the disturbance structure 20 and the pipe wall of the intermediate section 13 gradually decreases along the axial direction of the liquid distribution pipe 10 from the inlet 101 towards the liquid distribution part 11, so that the fluid flow rate gradually increases, and the disturbance of the fluid by the disturbance member 22 gradually intensifies, and the gradually decreasing arrangement plays a role of buffer transition.

[0044] As shown in the specific embodiment, Figure 1 and Figure 2 In an optional embodiment, the liquid distribution part 11 is provided with a mounting groove 112 spaced apart from the liquid distribution hole 111, and along the axial direction of the liquid distribution pipe 10, the mounting groove 112 is recessed inwardly from the surface of the liquid distribution part 11 towards the liquid distribution cavity 102; the bottom of the disturbance structure 20 is provided with a mounting part 24 connected to the flow guide part 21, the mounting part 24 is inserted into the mounting groove 112 and connected to the groove wall of the mounting groove 112, and the groove wall of the mounting groove 112 and the mounting part 24 can form mutual limiting, which is simple in structure. For example, the liquid distribution part 11 and the mounting part 24 are connected by welding. In a specific embodiment, the mounting groove 112 extends along the circumferential direction of the liquid distribution pipe 10 and is arranged close to the pipe wall of the liquid distribution pipe 10.

[0045] The technical features of the above-described embodiments can be combined in any manner. In order to make the description concise, not all possible combinations of the technical features in the above-described embodiments are described, however, as long as the combinations of the technical features do not exist contradictions, they should be considered as the scope of the present disclosure.

[0046] The above-described embodiments are merely illustrative of several embodiments of the present application, which are described in more detail and in a specific manner, but should not be construed as limiting the scope of the patent application. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
