Description

Technical Field

[0001] The invention relates to the technical field of server water cooling mechanisms, and in particular to a server water cooling main water channel structure. Background Art

[0002] The rapid development of information technology has made data centers an indispensable infrastructure for society. High-density computing devices, while bringing efficient computing, also bring serious heat dissipation problems. Therefore, traditional air cooling is no longer sufficient to solve the current high power consumption and heat dissipation problems. Liquid-cooled servers have emerged under this circumstance. Liquid-cooled servers are servers that use a liquid as a cooling medium. The coolant, such as water, is driven by a pump and flows through the main pipeline to the water distribution pipeline in the cold plate for circulation, taking away the heat released by the heat source to achieve the purpose of cooling.

[0003] The core component of direct liquid cooling is the liquid cooling plate, which has a flow channel structure inside, providing a place for forced convection heat exchange between the heat source and the cooling medium. The performance of the liquid cooling plate is the key to whether the liquid cooling system can meet the heat dissipation needs of the heat source. At present, liquid cooling plates are mainly divided into traditional liquid cooling plates, microchannel liquid cooling plates and porous metal liquid cooling plates. Among them, traditional liquid cooling plates are mainly divided into buried tube type and deep hole drilling type, which have the characteristics of simple manufacturing process, low application cost and good fluidity.

[0004] In addition to considering the liquid cooling plate, improper pipe design, pipe material selection or pipe welding method of the server water cooling main pipe will also directly lead to leakage or bursting of the pipe during use, threatening the safety of the computer room. Therefore, from the perspective of the server life cycle, it is urgent to develop a server water cooling main water pipe structure that can both enhance the strength of the main water pipe and reduce the production cost.

When the connection is not required, the second bypass hole 43 is blocked.

[0051] A method for manufacturing a water-cooled main water circuit structure for a server: the water circuit assembly 100 is assembled and connected in advance, and then the connecting pipe reinforcement block assembly 120, the central water inlet pipe reinforcement block assembly 130, the return water pipe reinforcement block assembly 140, and the return water manifold reinforcement block assembly 150 are respectively covered and installed on the corresponding water pipes and faucets, and the corresponding components of the reinforcement block assembly are reliably aligned and fixed on the corresponding pipes and faucets of the water circuit assembly 100 by brazing or epoxy resin bonding.

[0052] In the specific implementation, the liquid inlet copper block 10, the liquid outlet copper block 20, the two liquid inlet side connecting copper blocks 30, the two liquid outlet side connecting copper blocks 40, the central water inlet pipe 50, the return water conduit 60 on both sides, the liquid inlet side connecting pipeline 70, and the liquid outlet side return water pipeline 80 are all made of copper material C1100;

[0053] The connecting pipe reinforcement block assembly 120 , the central water inlet pipe reinforcement block assembly 130 , the return pipe reinforcement block assembly 140 , and the return manifold reinforcement block assembly 150 are all made of AL6063.

[0054] When the reinforcing block assembly is arranged around the outer periphery of the copper water pipe by the soldering process, the liquid inlet copper block 10, the liquid outlet copper block 20, the two liquid inlet side connecting copper blocks 30, the two liquid outlet side connecting copper blocks 40, the central water inlet pipe 50, the return water manifolds 60 on both sides, the liquid inlet side connecting pipeline 70, the liquid outlet side return water pipeline 80, the connecting pipeline reinforcing block assembly 120, the central water inlet pipe reinforcing block assembly 130, the return water pipeline reinforcing block assembly 140, and the return water manifold reinforcing block assembly 150 are each nickel-plated and then welded, which has the advantage of greatly improving the strength; the oxide film and pollutants on the contact surface of the reinforcing block assembly and the copper water pipe assembly are removed by flux, and the solder is made To get good wetting, use the soldering iron tip to heat the base material to the appropriate temperature; when the temperature of the base material reaches the melting point of the solder (about 250℃), supply solder wire, control the soldering amount, and supply the solder wire in an appropriate amount. When the solder reaches the appropriate amount and a contoured solder joint is observed to be formed, remove the soldering iron tip; soldering connection can greatly improve the welding strength, significantly improve the quality of welded products, and increase welding efficiency. Compared with other processes for the same product, the soldering process reduces the impact of the heat generated during the welding process on non-welding parts, and can adapt to a variety of welding needs. Whether it is manual welding or automated production lines, it plays an important role;

[0055] The server water cooling main water pipeline is welded with AL6063 wrapped with copper C1100 using the soldering process. The strength of AL6063 can be significantly improved after heat treatment, and it has excellent welding performance. The design implements the copper C1100 main water pipeline and AL6063 wrapped welding to enhance the strength of the pipeline. Compared with the deep hole drilling process, the cost is reduced by 1 times, and the welding efficiency is high and the weldability is strong, and the product qualification rate has been greatly improved.

[0056] When epoxy resin glue is used to bond the reinforcement block assembly around the outer periphery of the copper water pipe, for surfaces that cannot be welded or have a more complicated welding process, epoxy resin glue is applied on the assembled contact surfaces of the reinforcement block assembly and the copper water pipe, and then they are assembled and cured at room temperature or heated to 100°C to accelerate the curing. In addition to the strength advantage, epoxy resin glue bonding also has the advantages of simple process and low cost compared with the soldering process.

[0057] AL6063 and copper material C1100 are bonded by epoxy resin adhesive. Its strong bonding force can greatly reduce the leakage rate of the main water pipeline. Compared with traditional welding, it will not produce thermal stress, and will not cause deformation and cracks of the material, thereby affecting the performance of the product. Compared with brazing, especially copper brazing, epoxy resin is lighter and thinner, which will greatly reduce the weight of the product and reduce the cost.

[0058] The server water cooling main water pipeline is formed by bonding AL6063 and copper C1100 together with epoxy resin adhesive. AL6063 has good corrosion resistance and good bonding strength, which can reduce the weight of the product while achieving good wrapping of the main water pipeline, greatly improving the service life of the server.

[0059] In addition to being applied to the water cooling main water pipeline of the server, the soldering process can also be applied to PCB boards, electronic components, integrated circuits, semiconductors and other electronic devices with high precision requirements; epoxy resin can also be used in the manufacture of composite materials, connecting different types of materials together to form high-performance composite materials;

[0060] Compared with the complicated deep hole drilling process, the water pipes in the main water circuit of the server water cooling are directly manufactured pipes, and then the corresponding reinforcement block assemblies are covered on the periphery of the water pipes. The assembly method of the reinforcement block assemblies and the water pipes is obtained by soldering or epoxy resin bonding, which greatly reduces the risk of leakage of the main water pipes and increases the strength of the main water pipes. It increases the strength of the main water pipes and reduces the production cost.

[0061] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
