[0028] Referring to Figures 1-3 The present application provides a flow distributor, comprising: an inlet main pipe 10, a central flow collecting device 20, a plurality of flow distribution pipes 30, and a plurality of terminal flow distribution assemblies 40 corresponding to the plurality of flow distribution pipes 30, wherein one end of the inlet main pipe 10 is in communication with a fluid source, the other end is in communication with the central flow collecting device 20, the first ends of the plurality of flow distribution pipes 30 are uniformly distributed on the central flow collecting device 20 and in communication with the central flow collecting device 20, the second ends of the plurality of flow distribution pipes 30 are in communication with the corresponding terminal flow distribution assemblies 40, and the terminal flow distribution assemblies 40 are used to communicate to target terminals.
[0029] In the present embodiment, fluid flows out of a fluid source, enters the inlet main pipe 10, flows into the central flow collecting device 20 through the inlet main pipe 10, and is collected once in the central flow collecting device 20. After the fluid is collected in the central flow collecting device 20, the fluid can be more evenly distributed to each flow distribution pipe 30. The flow distribution pipes 30 are uniformly distributed on the central flow collecting device 20, and the fluid can be distributed as evenly as possible to the terminal flow distribution assemblies 40 after passing through the flow distribution pipes 30. The terminal flow distribution assemblies 40 distribute the fluid to each part that needs fluid, thereby achieving uniform distribution.
[0030] In one embodiment, the central flow collecting device 20 is a cylindrical hollow structure, the plurality of flow distribution pipes 30 are uniformly distributed on the side wall of the central flow collecting device 20, and the inlet main pipe 10 is in communication with at least one end of the flow distributor. Fluid enters the upper end or the lower end of the central flow collecting device 20 from the inlet main pipe 10, avoiding the impact of fluid on the side wall of the central flow collecting device 20. At the same time, the flow distribution pipes 30 are uniformly distributed on the side wall of the central flow collecting device 20, and the fluid pressure on the side wall is relatively uniform when the fluid enters the flow distribution pipes 30. Therefore, the fluid entering each flow distribution pipe 30 is relatively uniform, and uniform distribution can be achieved.
[0031] In order to more evenly distribute the flow and reduce the impact of the fluid on the side wall of the central flow collector 20, in an embodiment, the inlet flow main pipe 10 includes an inlet flow pipe 11, an upper main pipe 12 and a lower main pipe 13, one end of the inlet flow pipe 11 is in communication with the fluid source, and the other end is in communication with one end of the upper main pipe 12 and the lower main pipe 13 respectively, the other end of the upper main pipe 12 is in communication with the upper end of the central flow collector 20, and the other end of the lower main pipe 13 is in communication with the lower end of the central flow collector 20. In this embodiment, the connection of the inlet flow pipe 11, the upper main pipe 12 and the lower main pipe 13 can be a tee structure, the fluid flows into the upper main pipe 12 and the lower main pipe 13 from the inlet flow pipe 11 respectively, and then enters the upper end and the lower end of the central flow collector 20 from the upper main pipe 12 and the lower main pipe 13 respectively, further reducing the impact of the fluid on the side wall, and the fluid can fill the inner cavity of the central flow collector 20 faster and more evenly, further ensuring that each flow distribution pipe 30 is evenly distributed.
[0032] The central flow collector 20 can be a cylindrical hollow structure or a polygonal hollow structure. In this embodiment, a cylindrical hollow structure is taken as an example for illustration, the flow distribution pipes 30 are evenly distributed on the side wall of the cylindrical hollow structure, and the number of the flow distribution pipes 30 can be four, eight, sixteen or more, which can evenly distribute the fluid into multiple paths.
[0033] In an embodiment, the diameter of the first end of the flow distribution pipe 30 is smaller than the diameter of the second end. When the fluid is distributed from the central flow collector 20 to the flow distribution pipe 30, the diameter increases from small to large, which can reduce the flow resistance in the pipe on the one hand, and the gas is slowed down by the expansion of the pipe on the other hand, so that the fluid entering the secondary flow distributor 41 is more gentle, avoiding impact and the flow rate of the fluid entering each branch is as uniform as possible.
[0034] Alternatively, the diameter of the flow distribution pipe 30 increases uniformly from the first end to the second end. The uniform increase of the diameter of the flow distribution pipe 30 can ensure that the pressure and flow rate of the fluid flowing in the flow distribution pipe 30 decrease uniformly, and the fluid flow is more uniform and gentle, preventing surge impact on the terminal flow distribution assembly 40.
[0035] In an embodiment, the terminal flow distribution assembly 40 includes a secondary flow distributor 41 and a plurality of branch connectors 42 in communication with the secondary flow distributor 41, wherein the inlet of the secondary flow distributor 41 is in communication with the second end of the flow distribution pipe 30, and the outlet of the secondary flow distributor 41 is in communication with the branch connector 42. The branch connector 42 is used to connect to the target terminal. In this embodiment, the fluid is collected and then distributed from the secondary flow distributor 41, which can ensure that the path of the fluid entering each branch connector 42 is basically the same, so that the fluid at each branch connector 42 can be distributed as uniformly as possible.
[0036] In one embodiment, the secondary diverter 41 can be a hollow fan-shaped structure, wherein the central angle of the inlet of the secondary diverter 41 is the same as the central angle of the outlet, the radius of the inlet is smaller than the radius of the outlet, the fluid is fanned out in the secondary diverter 41, and the fan-shaped secondary diverter 41 makes the paths from the inlet to each branch inlet as similar as possible, thereby achieving equal distribution of flow.
[0037] In this embodiment, there can be four, eight, sixteen, or more branch connectors 42. The number of branches can be adjusted according to the requirements and the number of secondary splitters 41, so that one branch can be split into more branches.
[0038] like Figure 4 The analysis results of the flow velocity inside the distributor shown are as follows: Figure 5 The pressure analysis results shown in the diagram indicate that the pressure on the splitter pipe 30 and the terminal splitter assembly 40 is uniform and only at the kPa level. Furthermore, the flow velocity (flow rate) at the secondary splitter 41 and each branch connector 42 is basically the same, which can effectively achieve the goal of uniform flow splitting.
[0039] In one embodiment, the distributor further includes a housing 50, which at least surrounds the outer side of the central collector 20, the plurality of distributor pipes 30, and the terminal distributor assembly 40. The housing 50 can be circular or polygonal. The central collector 20 can be located at the center of the housing 50, and the terminal distributor assemblies 40 can be evenly distributed on the sidewalls of the housing 50. For example, when the housing 50 is polygonal, in order to ensure that the fluid path length in each terminal distributor is basically the same, the terminal distributor assemblies 40 can be arranged on each edge of the polygon to achieve uniform flow distribution.
[0040] In the above embodiments of this application, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions of other embodiments.
[0041] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
