Description

Technical Field

[0001] This invention relates to a liquid distributor and its manufacturing method, particularly a liquid distributor and its manufacturing method suitable for server liquid cooling systems. Background Technology

[0002] In recent years, rapid technological advancements have increased the computational demands on servers. To reduce the heat generated during server operations, liquid cooling systems are commonly used to cool various heat-generating electronic components. These components are distributed across multiple chassis within the server, requiring distribution pipes installed on the server racks to facilitate the delivery of coolant.

[0003] However, the precision of the distribution tubes is often reduced due to the ambient temperature during manufacturing, requiring repeated processing to meet dimensional requirements. Therefore, providing a distribution tube and its manufacturing method that avoids the high manufacturing costs caused by repeated processing has become a pressing issue for those skilled in the art. Summary of the Invention

[0004] The present invention provides a method for manufacturing a liquid separator and a liquid separator that eliminates the need for repeated processing of the liquid separator, thereby saving manufacturing costs while meeting the accuracy requirements of the liquid separator.

[0005] An embodiment of the present invention discloses a method for manufacturing a liquid separator, comprising the following steps: processing a flow tube to form a manifold having a plurality of liquid dispensing holes and a plurality of fixing parts; and welding an inlet connector and an outlet connector to opposite ends of the manifold, wherein the welded inlet connector and outlet connector are respectively connected to the manifold.

[0006] Another embodiment of the present invention discloses a liquid distributor suitable for a liquid cooling system of a server. The liquid distributor includes a manifold, an inlet connector, and an outlet connector. The manifold has multiple dispensing holes and multiple fixing portions. The dispensing holes are used to connect to multiple connectors. The dispensing holes and fixing portions are located on different sides of the manifold. The liquid distributor is mounted on a server rack via the fixing portions. The inlet connector and the outlet connector are respectively welded to opposite ends of the manifold. Each of the inlet connector and the outlet connector connects to the manifold. The inlet connector and the outlet connector are respectively used to provide an inlet pipe and an outlet pipe.

[0007] According to the manufacturing method and the liquid separator disclosed in the above embodiments, the liquid separator orifice and the fixing part can be formed by processing, and the welding of the inlet and outlet connectors is far away from the liquid separator orifice and the fixing part. Therefore, the accuracy of the liquid separator orifice and the fixing part can be maintained after welding, and the liquid separator orifice and the fixing part do not need to be processed again, thereby saving time and cost in manufacturing the liquid separator.

[0030] Please refer to Figures 1 to 2 ,in Figure 1 A flowchart illustrating a method for manufacturing a separator according to an embodiment of the present invention, and Figure 2 for Figure 1 A detailed flow chart illustrating the manufacturing method of the separator.

[0031] like Figure 1 As shown, the manufacturing method of the distributor disclosed in this embodiment may include the following steps: Step S101, processing a flow tube to form a manifold having multiple dispensing holes and multiple fixing parts; Step S102, performing fine processing on the dispensing holes and fixing parts; Step S103, performing a cleaning procedure on the manifold; Step S104, clamping a clamping position of the manifold with a jig; Step S105, welding an inlet adapter and an outlet adapter to opposite ends of the manifold; and Step S106, performing a simple cleaning procedure on the distributor.

[0032] like Figure 2 As shown, step S101 may include the following steps: step S1011, thinning a first sidewall of the flow tube to form a reference surface on the first sidewall; step S1012, thinning a second sidewall of the flow tube and drilling a hole in the second sidewall to form a distributing hole; step S1013, thinning a third sidewall of the flow tube; and step S1014, cutting a fourth sidewall of the flow tube to form a stepped fixing portion on the fourth sidewall. Note that steps S1011 to S1014 included in step S101 can be performed by at least one of computer numerical control (CNC) machining, waterjet machining, and cold drawing (also known as cold drawing or cold stretching), but the present invention is not limited thereto.

[0033] In this embodiment, step S105 may include the following steps: Step S1051, the liquid inlet pipe and the liquid outlet pipe are welded to the opposite ends of the manifold by tungsten inert gas welding or laser welding respectively.

[0034] Next, please refer to the steps above. Figures 3 to 12 ,in Figures 3 to 12 for Figure 1 A schematic diagram illustrating the manufacturing process of the separator.

[0035] like Figure 3 and Figure 4 As shown, the flow tube 9 is made of a tube material. The flow tube 9 has a first sidewall 9a, a second sidewall 9b, a third sidewall 9c and a fourth sidewall 9d that are connected sequentially and adjacently.

[0036] In step S101, the convection tube 9 is processed to form a manifold 11, wherein the manifold 11 has a plurality of liquid distribution holes 111 and a plurality of fixing parts 112.

[0037] Specifically, in step S1011, the first sidewall 9a of the flow tube 9 can be thinned. For example... Figure 5 As shown, a reference surface RS can be formed on the thinned first sidewall 9a to serve as a reference for subsequent steps. Furthermore, the thinned first sidewall 9a can have a predetermined wall thickness PT of at least 5 millimeters (mm) to ensure the structural strength of the finished product.

[0038] Next, in step S1012, the second sidewall 9b of the flow tube 9 can be thinned and a hole drilled in the second sidewall 9b. For example... Figure 6 and Figure 7 As shown, the surface MS of the thinned second sidewall 9b can be used as a reference for drilling. Furthermore, multiple liquid distribution holes 111 penetrating the second sidewall 9b will be formed on the drilled second sidewall 9b.

[0039] Next, in step S1013, the third sidewall 9c of the flow tube 9 can be thinned. Similarly, the thinned third sidewall 9c can have a predetermined wall thickness PT to ensure the structural strength of the finished product, such as... Figure 8 As shown.

[0040] Next, in step S1014, the fourth sidewall 9d of the cuttable flow tube 9 is cut. For example... Figure 9 and Figure 10 As shown, multiple stepped fixing portions 112 are formed on the cut fourth sidewall 9d, and the fixing portions 112 are located on the opposite side of the dispensing hole 111. Note that the wall thickness of each of the first sidewall 9a to the fourth sidewall 9d may be different, and the present invention is not limited thereto.

[0041] Next, in step S102, the dispensing hole 111 and the fixing part 112 can be finely machined to improve the dimensional accuracy of the dispensing hole 111 and the fixing part 112.

[0042] Next, in step S103, a cleaning procedure can be performed on the manifold 11 to remove the processing debris generated on the manifold 11 due to the aforementioned steps.

[0043] Next, in step S104, a jig (not shown) can be used to clamp the manifold 11 at the clamping position CP near its end to facilitate subsequent welding on the manifold 11. Specifically, as follows... Figure 11As shown, the two opposite ends of the manifold 11 can be used as welding positions WP, and the welding positions WP can be farther away from the liquid distribution hole 111 and the fixing part 112 than the clamping position CP. Alternatively, the clamping position CP can be located between the liquid distribution hole 111 and the welding position WP. Or, the clamping position CP can be located between the fixing part 112 and the welding position WP.

[0044] By designing the clamping position CP, the heat generated at the welding position WP during welding can be conducted to the fixture via the clamping position CP during subsequent welding steps. This prevents the heat generated at the welding position WP from being conducted to the dispensing hole 111 and the fixing part 112, thus avoiding affecting the previous machining accuracy of the dispensing hole 111 and the fixing part 112.

[0045] Next, in step S105, an inlet connector 12 and an outlet connector 13 can be welded to the welding positions WP at opposite ends of the manifold 11. Alternatively, in step S1051, the inlet connector 12 and the outlet connector 13 can be welded to the welding positions WP at opposite ends of the manifold 11 using tungsten inert gas welding (TIG welding) or laser welding. Figure 11 and Figure 12 As shown, the welded liquid inlet pipe 12 and liquid outlet pipe 13 are each connected to the manifold 11.

[0046] The shape of the dispenser 10 can be completed through steps S101 to S105.

[0047] Next, in step S106, a simple cleaning procedure can be performed on the distributor 10. Since no machining is performed in steps S104 to S105, no machining debris is generated. Therefore, only a simple cleaning procedure is needed for the distributor 10 in step S106. This saves manufacturing time and costs.

[0048] The liquid dispenser 10 manufactured through the above steps, after preliminary and fine machining, can form the liquid dispensing orifice 111 and the fixing part 112, which require high precision. Furthermore, the welding of the inlet connector 12 and the outlet connector 13 is performed at welding positions WP, far from the liquid dispensing orifice 111 and the fixing part 112. Therefore, the precision of the liquid dispensing orifice 111 and the fixing part 112 can be maintained after welding, eliminating the need for further precision machining of the liquid dispensing orifice 111 and the fixing part 112, thereby saving time and cost in manufacturing the liquid dispenser 10.

[0049] Furthermore, traditional processes use arc welding to fix multiple gaskets and adapters to the pipe. In contrast, the high-precision dispensing hole 111 and fixing part 112 of this invention are formed through preliminary and fine machining, which can eliminate the need for expensive large vacuum arc welding furnaces required for arc welding, thereby increasing production capacity. It can also avoid the high temperature affecting the precision of adjacent arc welded gaskets or adapters when welding gaskets or adapters one by one.

[0050] The manufactured liquid distributor 10 can be mounted on the rack of a server (not shown) via the fixing part 112. The liquid distribution hole 111, the liquid inlet adapter 12 and the liquid outlet adapter 13 can be connected to multiple connectors, a liquid inlet pipe and a liquid outlet pipe (not shown) respectively. The working fluid transported by the liquid inlet pipe is distributed to multiple connectors through the liquid distributor 10 and flows through the server chassis. After absorbing the heat generated by the electronic components in the chassis, it flows from the liquid distributor 10 to the liquid outlet pipe to complete the heat exchange. It can be used in the liquid cooling system of the server.

[0051] According to the manufacturing method and the liquid separator of the above embodiments, through preliminary processing and fine processing, a liquid separator hole and a fixing part requiring high precision can be formed. Furthermore, the welding of the inlet and outlet transfer pipes is performed at welding positions far from the liquid separator hole and the fixing part. Therefore, the precision of the liquid separator hole and the fixing part can be maintained after welding, eliminating the need for further precision processing of the liquid separator hole and the fixing part, thereby saving time and cost in manufacturing the liquid separator.

[0052] Although the present invention has been disclosed above with reference to the foregoing embodiments, it is not intended to limit the present invention. Any person skilled in the art may make some modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of patent protection of the present invention shall be determined by the scope of protection of the appended claims.
