It should be understood that this disclosure can have various variations in different embodiments without departing from the scope of this disclosure, and the descriptions and drawings therein are illustrative in nature and not intended to limit this disclosure.

[0018] In the following description of various exemplary embodiments of this disclosure, reference is made to the accompanying drawings, which form part of this disclosure, and which illustrate by way of example different exemplary structures, systems, and steps that can implement various aspects of this disclosure. It should be understood that other specific embodiments of the components, structures, exemplary devices, systems, and steps may be used, and structural and functional modifications may be made without departing from the scope of this disclosure. Furthermore, while the terms “above,” “between,” “within,” etc., may be used in this specification to describe different exemplary features and elements of this disclosure, these terms are used herein only for convenience, such as the orientation according to the examples described in the accompanying drawings. Nothing in this specification should be construed as requiring a specific three-dimensional orientation of the structure to fall within the scope of this disclosure.

[0019] See Figure 1The illustration shows a perspective view of the dispenser proposed in this disclosure. In this exemplary embodiment, the dispenser proposed in this disclosure is described as a mesh dispenser applied to a refrigeration system. It will be readily understood by those skilled in the art that various modifications, additions, substitutions, deletions, or other changes may be made to the specific embodiments described below in order to apply the relevant designs of this disclosure to other types of dispensers or other application scenarios, and these changes are still within the scope of the principles of the dispenser proposed in this disclosure.

[0020] like Figure 1 As shown, in one embodiment of this disclosure, the dispenser includes a body 100 and a positioning plate 200. The body 100 has an inner cavity 101 and a first end 110 and a second end 120 in a first direction, which can be referred to as direction D1 shown in the figures. The first end 110 is provided with an inlet pipe 111 communicating with the inner cavity 101, and the second end 120 is provided with a plurality of outlet pipes 121 respectively communicating with the inner cavity 101, the plurality of outlet pipes 121 being used to connect to a plurality of piping respectively. (See attached figure) Figures 2 to 6 , Figure 2 The diagram shows a typical plan view of the distributor; Figure 3 The middle section represents the way along Figure 1 A cross-sectional view of line AA in the diagram; Figure 4 China representatively shows Figure 3 A three-dimensional image; Figure 5 China representatively shows Figure 3 An enlarged view of part B in the image; Figure 6 A perspective view of the positioning plate 200 of the dispenser is shown in the figure. The structure, connection method, and functional relationship of the main components of the dispenser proposed in this disclosure will be described in detail below with reference to the above-mentioned figures.

[0021] like Figures 1 to 5As shown, in one embodiment of this disclosure, the positioning plate 200 is disposed in the inner cavity 101 of the body 100, and the positioning plate 200 is located on the cavity wall corresponding to the end face of the second end 120 of the inner cavity 101. For example, one side surface of the positioning plate 200 is in contact with the cavity wall. The term "cavity wall corresponding to the end face of the second end 120" can be understood as the inner surface of the end wall (or end plate) of the body 100 perpendicular to the axial direction of the second end 120. The positioning plate 200 is provided with a plurality of first through holes 210, each of which corresponds to a plurality of liquid outlet pipes 121. The first through holes 210 and the corresponding liquid outlet pipes 121 are arranged concentrically. For example, the axes of the first through holes 210 and the liquid outlet pipes 121 extend parallel to a first direction, and their axes coincide. The first direction can be referred to as direction D1 shown in the figure. The first through holes 210 communicate with the liquid outlet pipes 121. The inner wall of the first through hole 210 is provided with a positioning part 220. The positioning part 220 forms a cavity that connects the first through hole 210 and the inner cavity 101. At least a portion of the orthographic projection of the positioning part 220 is located within the cavity of the outlet pipe 121 along the axial direction of the outlet pipe 121. Through the above structural design, when the piping is connected to the outlet pipe 121, this disclosure uses the positioning part 220 to position the piping and limit the insertion depth of the piping. Since multiple positioning parts 220 are respectively set in multiple first through holes 210 of the same positioning plate 200, multiple piping are limited by a positioning plate 200. This ensures the consistency of the limiting dimensions of each piping and the consistency of the assembly depth between each piping and the outlet pipe 121, making the assembly gap of each piping more uniform. This ensures the consistency and reliability of the distributor's distribution function, while reducing weld blockage and improving the welding quality of the product. Furthermore, compared to existing solutions that use bubble placement on piping to position the relative positions of piping and outlet pipes, this disclosure eliminates the need for bubble placement on piping, avoiding issues such as breakdown and leakage caused by bubble placement. Moreover, for multiple piping, it is difficult to ensure consistency when setting bubble placement on each piping individually, thus affecting the consistency of the limiting dimensions of each piping. This disclosure uses a positioning plate 200 to simultaneously limit multiple piping, which can overcome the above problems and ensure the consistency of the limiting dimensions of each piping.

[0022] like Figure 3As shown, in one embodiment of this disclosure, the thickness of the positioning part 220 can be less than the axial length of the first through hole 210; in other words, the dimension of the positioning part 220 in the first direction is smaller than the dimension of the first through hole 210 in the first direction. Accordingly, a stepped structure can be formed on the side of the positioning part 220 facing the outlet pipe 121, for example, referring to the stepped surface 221 shown in the figure (i.e., the surface of the positioning part 220 facing the second end 120). With the above structural design, when the piping is connected to the outlet pipe 121, the piping part is inserted into the outlet pipe 121 and further inserted into the first through hole 210, and the inserted end of the piping abuts against the stepped surface 221 of the stepped structure, thereby achieving positioning. Based on this, this disclosure can utilize the positioning part 220 to achieve a partial flow guiding function when fluid enters the piping, reducing the impact of turbulence.

[0023] like Figure 6 As shown, in one embodiment of this disclosure, a positioning part 220 may protrude from the inner wall of the first through hole 210, and the cross-section of the positioning part 220 may be annular. Through the above structural design, this disclosure can utilize the annular positioning part 220 to limit the piping at various positions in the circumferential direction, while simplifying the structural complexity of the positioning part 220 and reducing its processing difficulty. In other embodiments of this disclosure, when a positioning part 220 protrudes from the inner wall of the first through hole 210, the cross-section of the positioning part 220 may also be of other shapes, such as arcuate, and is not limited to this embodiment.

[0024] Reference Figure 7 , Figure 7 The diagram shows a partially enlarged view of the positioning plate 200 in another exemplary embodiment of the dispenser that embodies the principles of this disclosure, specifically showing an enlarged structure of a first through-hole 210 region of the positioning plate 200.

[0025] like Figure 7 As shown, in one embodiment of this disclosure, the inner wall of the first through hole 210 may be provided with a plurality of positioning portions 220, which are arranged at intervals along the circumference of the first through hole 210, and the cross-section of a single positioning portion 220 may be arc-shaped. Through the above structural design, this disclosure can reduce the obstruction of the positioning portions 220 on the piping flow area, thereby reducing the impact of the positioning portions 220 on the liquid flow rate.

[0026] Reference Figure 8 , Figure 8 The diagram shows a partially enlarged view of the positioning plate 200 in another exemplary embodiment of the dispenser that embodies the principles of this disclosure, specifically showing an enlarged structure of a first through-hole 210 region of the positioning plate 200.

[0027] like Figure 8As shown, in one embodiment of this disclosure, the inner wall of the first through hole 210 may be provided with a plurality of positioning portions 220, which are arranged at intervals along the circumference of the first through hole 210. The cross-section of a single positioning portion 220 may be a point-like structure. Accordingly, when the piping is connected to the outlet pipe 121, the piping passes through the outlet pipe 121 and abuts against the side surface of the positioning portion 220 facing the outlet pipe 121. Through the above structural design, this disclosure can further reduce the obstruction of the piping flow area by the positioning portion 220, thereby further reducing the impact of the positioning portion 220 on the outlet flow rate.

[0028] In one embodiment of this disclosure, the outlet pipe 121 is used to connect to the piping. When the piping is connected to the outlet pipe 121, the piping passes through the outlet pipe 121 and abuts against the stepped surface 221 of the stepped structure. Based on this, the diameter of the first through hole 210 can be equal to the inner diameter of the outlet pipe 121, and the radial width of the positioning part 220 in the first through hole 210 can be equal to the wall thickness of the piping. Through the above structural design, when the piping is connected to the outlet pipe 121, the piping is inserted into the outlet pipe 121 and further inserted into the first through hole 210. The outer wall of the piping contacts the inner wall of the outlet pipe 121 and also contacts the inner wall of the first through hole 210. Therefore, this disclosure can further achieve radial positioning of the piping using the first through hole 210. Furthermore, since the width of the positioning part 220 is equal to the wall thickness of the piping, this disclosure can also ensure that the positioning part 220 does not obstruct the flow area of ​​the piping, thereby ensuring that the outlet flow rate is not affected by the positioning part 220. In other embodiments of this disclosure, the width of the positioning part 220 may be less than the wall thickness of the piping, and is not limited to this embodiment.

[0029] Reference Figure 9 , Figure 9 The diagram shows a partially enlarged view of the positioning plate 200 in another exemplary embodiment of the dispenser that embodies the principles of this disclosure, specifically showing an enlarged structure of a first through-hole 210 region of the positioning plate 200.

[0030] like Figure 9As shown, in one embodiment of this disclosure, the thickness of the positioning part 220 can be equal to the thickness of the positioning plate 200, and in the first direction, the two side surfaces of the positioning part 220 are flush with the two side surfaces of the positioning plate 200. Based on this, a plurality of positioning parts 220 can protrude from the inner wall of the first through hole 210, and the plurality of positioning parts 220 are arranged at intervals along the circumference of the first through hole 210. The cross-section of a single positioning part 220 can be arc-shaped. Through the above structural design, this disclosure simplifies the processing difficulty of setting the positioning part 220 in the first through hole 210. In other embodiments of this disclosure, when a plurality of positioning parts 220 protrude from the inner wall of the first through hole 210, the cross-section of a single positioning part 220 can also be other shapes, such as a dotted structure, and is not limited to this embodiment.

[0031] Reference Figure 10 , Figure 10 The diagram shows a partially enlarged cross-sectional view of a dispenser that embodies the principles of this disclosure in another exemplary embodiment, specifically showing an enlarged cross-sectional structure of the dispenser in a region of a first through-hole 210.

[0032] like Figure 10 As shown, in one embodiment of this disclosure, the end of the positioning part 220 away from the liquid outlet pipe 121 may be provided with a rounded corner structure 222. Through the above structural design, this disclosure can reduce flow resistance by utilizing the rounded corner structure 222, accelerate the flow speed of the medium when it flows through the first through hole 210 and the positioning part 220, and ensure that the refrigerant flow rate is not affected.

[0033] Reference Figure 11 , Figure 11 The diagram shows a partially enlarged cross-sectional view of a dispenser that embodies the principles of this disclosure in another exemplary embodiment, specifically showing an enlarged cross-sectional structure of the dispenser in a region of a first through-hole 210.

[0034] like Figure 10 As shown, in one embodiment of this disclosure, the end of the positioning part 220 away from the liquid outlet pipe 121 may be provided with a chamfered structure 223. Through the above structural design, this disclosure can reduce flow resistance by utilizing the chamfered structure 223, accelerate the flow speed of the medium when it flows through the first through hole 210 and the positioning part 220, and ensure that the refrigerant flow rate is not affected.

[0035] like Figure 1 , Figure 3 and Figure 4As shown, in one embodiment of this disclosure, the cavity wall of the inner cavity 101 may be provided with a positioning protrusion 130, which is spaced apart from the first end 110 and the second end 120 along the first direction. Based on this, the periphery of the positioning plate 200 is provided with a flange 230 bent towards the first end 110, which abuts against the side of the positioning protrusion 130 near the second end 120. Through the above structural design, this disclosure utilizes the positioning protrusion 130 to achieve the positioning of the positioning plate 200 in the inner cavity 101, that is, the positioning plate 200 is jointly positioned in the first direction by the positioning protrusion 130 and the cavity wall of the inner cavity 101 at the second end 120.

[0036] like Figure 3 and Figure 4 As shown, in one embodiment of this disclosure, the positioning protrusion 130 can be a structure integrally formed by the body 100. For example, by integral die casting, spinning or other processes, a part of the body 100 is directly pressed inward to form an inwardly bent and recessed protrusion structure.

[0037] like Figure 3 and Figure 4 As shown, in one embodiment of this disclosure, the dispenser may include a perforated plate 300 disposed in the inner cavity 101 of the body 100 and located between the positioning plate 200 and the first end 110. The perforated plate 300 is provided with a plurality of second through holes 310. Specifically, when the body 100 is provided with a positioning protrusion 130, the perforated plate 300 may be located on the side of the positioning protrusion 130 near the first end 110 and positioned by the positioning protrusion 130.

[0038] In one embodiment of this disclosure, the positioning plate 200 may be made of stainless steel.

[0039] Reference Figure 12 , Figure 12 The diagram shows a partially enlarged cross-sectional view of a dispenser that embodies the principles of this disclosure in another exemplary embodiment, specifically showing an enlarged cross-sectional structure of the dispenser in a region of a first through-hole 210.

[0040] like Figure 12 As shown, in one embodiment of this disclosure, the dispenser and Figures 1 to 11 The dispensers shown have largely the same structural design, the difference being that the diameter of the first through hole 210 is smaller than the inner diameter of the outlet pipe 121, meaning that the inner wall of the positioning plate 200 forming the first through hole 210 does not have a positioning part 220. In other words, Figure 12The embodiment shown can also be understood as having a positioning part 220 with an annular cross-section on the inner wall of the first through hole 210, wherein the thickness of the positioning part 220 is equal to the thickness of the positioning plate 200, and the two side surfaces of the positioning part 220 in the first direction are flush with the two side surfaces of the positioning plate 200 respectively.

[0041] It should be noted that the dispensers shown in the accompanying drawings and described in this specification are merely a few examples among many dispensers capable of employing the principles of this disclosure. It should be clearly understood that the principles of this disclosure are by no means limited to any details of the dispensers shown in the accompanying drawings or described in this specification, or to any component of the dispensers.

[0042] In summary, the dispenser disclosed herein includes a body 100 and a positioning plate 200. The first end 110 of the body 100 is provided with an inlet pipe 111 communicating with an inner cavity 101, and the second end 120 is provided with multiple outlet pipes 121 respectively communicating with the inner cavity 101. The positioning plate 200 is disposed in the inner cavity 101 and located on the cavity wall corresponding to the end face of the second end 120. The positioning plate 200 is provided with multiple first through holes 210, each corresponding to one of the multiple outlet pipes 121 and arranged concentrically, with the first through holes 210 communicating with the outlet pipes 121. A positioning portion 220 protrudes from the inner wall forming the first through hole 210, and the positioning portion 220 forms a cavity communicating with the first through hole 210 and the inner cavity 101. Along the axial direction of the outlet pipe 121, at least a portion of the orthographic projection of the positioning portion 220 is located within the cavity range of the outlet pipe 121. Through the above structural design, when the piping is connected to the liquid outlet pipe 121, this disclosure uses the positioning part 220 to position the piping and limit the insertion depth of the piping. Since multiple positioning parts 220 are respectively set in multiple first through holes 210 of the same positioning plate 200, multiple piping are limited by one positioning plate 200. This ensures the consistency of the limiting dimensions of each piping and the consistency of the assembly depth between each piping and the liquid outlet pipe 121, making the assembly gap of each piping more uniform, ensuring the consistency and reliability of the distributor's distribution function, and reducing weld blockage and improving the welding quality of the product.
