[0047] Please refer to Figures 1 to 2 , in which Figure 1The flowchart shown for the manufacturing method of a liquid distributor according to an embodiment of the present utility model, and Figure 2 is Figure 1 The detailed flowchart shown for the manufacturing method of the liquid distributor.
[0048] As Figure 1 shown, the manufacturing method of the liquid distributor disclosed in this embodiment may include the following steps: Step S101, processing a flow tube to form a manifold having a plurality of liquid distribution holes and a plurality of fixing portions; Step S102, performing fine processing on the liquid distribution holes and the fixing portions; Step S103, performing a cleaning procedure on the manifold; Step S104, clamping a clamping position of the manifold with a jig; Step S105, respectively welding an inlet liquid adapter tube and an outlet liquid adapter tube at opposite ends of the manifold; and Step S106, performing a simple cleaning procedure on the liquid distributor.
[0049] As Figure 2 shown, Step S101 may include the following steps: Step S1011, thinning a first side wall of the flow tube to form a reference surface on the first side wall; Step S1012, thinning a second side wall of the flow tube and drilling holes in the second side wall to form liquid distribution holes; Step S1013, thinning a third side wall of the flow tube; and Step S1014, machining a fourth side wall of the flow tube to form a stepped fixing portion on the fourth side wall. It should be noted that Steps S1011 to S1014 included in Step S101 can be completed by at least one of computer numerical control (CNC) machining, water jet machining, and cold drawn (which can also be referred to as cold drawing) machining, but the present utility model is not limited thereto.
[0050] In this embodiment, Step S105 may include the following steps: Step S1051, respectively welding the inlet liquid adapter tube and the outlet liquid adapter tube at opposite ends of the manifold by tungsten inert gas shielded welding or laser welding.
[0051] Next, please refer to Figures 3 to 12 in combination with the above steps, where Figure 3 is a schematic structural diagram of the flow tube; Figure 4 is a schematic diagram of the end face of the flow tube; Figure 5 is a schematic diagram of the first side wall of the manifold; Figure 6 is a schematic diagram of the second side wall of the manifold; Figure 7 is a schematic structural diagram of one perspective of the manifold; Figure 8 is a schematic diagram of the third side wall of the manifold; Figure 9 is a schematic diagram of the fourth side wall of the manifold; Figure 10 is a schematic structural diagram of another perspective of the manifold. Figure 11 is an exploded schematic diagram of the liquid distributor; Figure 12This is a schematic diagram of the structure of the dispenser.
[0052] like Figure 3 and Figure 4 As shown, the flow tube 9 is a tube material and has a first side wall 9a, a second side wall 9b, a third side wall 9c and a fourth side wall 9d which are connected in sequence and adjacent to each other.
[0053] In step S101 , the flow tube 9 is processed to form a branching tube 11 , wherein the branching tube 11 has a plurality of liquid separation holes 111 and a plurality of fixing portions 112 .
[0054] Specifically, in step S1011, the first side wall 9a of the flow tube 9 may be thinned. Figure 5 As shown, a reference surface RS can be formed on the thinned first side wall 9a to serve as a reference for subsequent steps. In addition, the thinned first side wall 9a can have a predetermined tube wall thickness PT of at least 5 mm to ensure the structural strength of the finished product.
[0055] Next, in step S1012, the second side wall 9b of the flow tube 9 may be thinned and a hole may be drilled in the second side wall 9b. Figure 6 and Figure 7 As shown, the surface MS of the thinned second side wall 9b can be used as a reference for drilling. In addition, a plurality of liquid separation holes 111 penetrating the second side wall 9b are formed on the drilled second side wall 9b.
[0056] Next, in step S1013, the third side wall 9c of the flow tube 9 may be thinned. Similarly, the thinned third side wall 9c may have a predetermined tube wall thickness PT to ensure the structural strength of the finished product, such as Figure 8 shown.
[0057] Next, in step S1014, the fourth side wall 9d of the flow tube 9 may be cut. Figure 9 and Figure 10 As shown, a plurality of stepped fixing portions 112 are formed on the cut fourth side wall 9d, and the fixing portions 112 are located on the opposite side of the liquid separation hole 111. Please note that the wall thicknesses of the first side wall 9a to the fourth side wall 9d may be different, and the present invention is not limited thereto.
[0058] It should be noted that a first side wall 9a, a second side wall 9b, a third side wall 9c and a fourth side wall 9d of the flow tube 9 are respectively the first side wall, a second side wall, a third side wall and a fourth side wall of the branch pipe 11 after processing. Taking the second side wall 9b as an example, it is the second side wall 9b of the flow tube 9 before thinning and drilling, and becomes the second side wall of the branch pipe 11 after thinning and drilling.
[0059] Next, in step S102, the liquid separation holes 111 and the fixing portion 112 can be finely processed to improve the dimensional accuracy of the liquid separation holes 111 and the fixing portion 112.
[0060] Next, in step S103, a cleaning process can be performed on the manifold 11 to remove the machining debris generated on the manifold 11 in the previous steps.
[0061] Next, in step S104, a jig (not shown separately) can be used to clamp the clamping position CP near the end of the manifold 11 to facilitate the subsequent welding step on the manifold 11. Specifically, as Figure 11 shown, the opposite ends of the manifold 11 can be used as the welding positions WP to be welded, and the welding positions WP can be farther from the liquid separation holes 111 and the fixing portion 112 than the clamping position CP. Or it can also be said that the clamping position CP can be located between the liquid separation holes 111 and the welding positions WP. Or it can also be said that the clamping position CP can be located between the fixing portion 112 and the welding positions WP.
[0062] By the design of the clamping position CP, when the subsequent welding step is performed, the heat generated at the welding position WP during welding can be thermally conducted to the jig through the clamping position CP, avoiding the heat generated at the welding position WP from being thermally conducted to the liquid separation holes 111 and the fixing portion 112 and affecting the previous machining accuracy of the liquid separation holes 111 and the fixing portion 112.
[0063] Next, in step S105, an inlet liquid transfer pipe 12 and an outlet liquid transfer pipe 13 can be welded to the welding positions WP at the opposite ends of the manifold 11 respectively. Or it can also be said that in step S1051, the inlet liquid transfer pipe 12 and the outlet liquid transfer pipe 13 can be welded to the welding positions WP at the opposite ends of the manifold 11 by tungsten inert gas welding (also known as TIG welding) or laser welding respectively. As Figure 11 and Figure 12 shown, the welded inlet liquid transfer pipe 12 and the outlet liquid transfer pipe 13 are each connected to the manifold 11.
[0064] By steps S101 to S105, the outer shape of the liquid separator 10 can be completed.
[0065] Next, in step S106, a simple cleaning process can be performed on the liquid separator 10. Since no machining is performed in steps S104 to S105 and no machining debris is generated, only a simple cleaning process needs to be performed on the liquid separator 10 in step S106. In this way, the manufacturing time cost and cost can be saved.
[0066] The liquid distributor 10 manufactured through the above steps can form the liquid distribution holes 111 and the fixing parts 112 that require high precision through preliminary processing and fine processing. Moreover, the welding of the liquid inlet adapter pipe 12 and the liquid outlet adapter pipe 13 is carried out at the welding position WP far away from the liquid distribution holes 111 and the fixing parts 112. Therefore, the precision of the liquid distribution holes 111 and the fixing parts 112 can still be maintained after welding, and there is no need to perform precision processing on the liquid distribution holes 111 and the fixing parts 112 again, thereby saving the time cost and expenditure cost for manufacturing the liquid distributor 10.
[0067] In addition, in the traditional process, multiple gaskets and adapter seats are fixed to the pipe by brazing. In contrast, the high-precision liquid distribution holes 111 and the fixing parts 112 in this case are formed through preliminary processing and fine processing, which can eliminate the need for an expensive large-scale vacuum brazing furnace required for brazing, thereby improving production capacity. It can also avoid the influence of high temperature on the precision of adjacent gaskets or adapter seats that have been welded when welding the gaskets or adapter seats one by one.
[0068] The manufactured liquid distributor 10 can be arranged on the rack of a server (not shown separately) through the fixing parts 112, and the liquid distribution holes 111, the liquid inlet adapter pipe 12, and the liquid outlet adapter pipe 13 can be respectively communicated with a plurality of connectors, a liquid inlet pipe, and a liquid outlet pipe (not shown separately). In this way, the working fluid conveyed by the liquid inlet pipe is distributed to the plurality of connectors through the liquid distributor 10 and flows through the chassis of the server. After absorbing the heat generated by the electronic components in the chassis, it then flows from the liquid distributor 10 to the liquid outlet pipe to complete the heat exchange, and thus it can be applied to the liquid cooling system of the server.
[0069] According to the manufacturing method of the liquid distributor and the liquid distributor of the above embodiment, through preliminary processing and fine processing, the liquid distribution holes and the fixing parts that require high precision can be formed, and the welding of the liquid inlet adapter pipe and the liquid outlet adapter pipe is carried out at the welding position far away from the liquid distribution holes and the fixing parts. Therefore, the precision of the liquid distribution holes and the fixing parts can still be maintained after welding, and there is no need to perform precision processing on the liquid distribution holes and the fixing parts again, thereby saving the time cost and expenditure cost for manufacturing the liquid distributor.
[0070] Although the present utility model is disclosed as the foregoing embodiments, it is not intended to limit the present utility model. Any person skilled in the relevant art, without departing from the spirit and scope of the present utility model, can make some modifications and refinements. Therefore, the scope of patent protection of the present utility model shall be determined by the scope defined by the appended claims of the present utility model.
