AI server liquid cooling Brazing cold plate

What are the key points in the production process of AI server liquid cooling water block brazing cold plate?The production process of AI server liquid cooling water block brazing cold plates is a precise and complex procedure that ensures efficient heat dissipation, Below are the production steps from Vansim for the brazed cold plate for the AI server CPU liquid cooling: Firstly, material selection. High - purity copper of Cu1100 and Cu1020 all be avaliable for the copper base and cover. Why choose the copper material for the water block rather than aluminum? For the high power CPU chips, More heat dissipation effiencent of copper became the top choice.Next comes the machining stage. Precision machining techniques such as CNC milling are used to create the fluid channels inside the cold plate. Include the roughless and flatness for the surface is critical. High performance CPU cooling plate usually design with the micro-channel cover for the water block inside. The micro fins as the flow channels inside, How does the the micro fins be machined? It can be machined by skiving fin process. High density fins be skived on a copper base, Conbined with the CNC machining to be a channel base for the water block.Then, Vacuum brazing process: Provides oxygen-free environment to prevent oxidation, ideal for high-purity copper, The temperature must exceed the brazing filler metal’s melting point , Copper brazing temperature usually need to be ~850°C ),Still need to remain below the base material’s melting point to avoid distortion;Another is the Pressure and Positioning: the water block are clamped or fixtured to maintain minimal gap during brazing, as excessive gaps reduce joint strength and thermal conductivity. This entire production process combines advanced materials, precise machining, and strict quality control to produce high - performance liquid cooling water block brazing cold plates for AI servers.

Hybrid Welding Process Cold Plates: Brazed and FSW cold plate Our new-generation aluminum cold plates break away from conventional internal channel machining and single welding processes. We have pioneered an integrated manufacturing chain combining Friction Stir Welding (FSW) and vacuum brazing. Based on extruded aluminum profiles, the two welding processes are deployed with well-divided functional roles. Without compromising sealing reliability and thermal performance, this solution delivers high efficiency, low cost and high-volume mass production capacity urgently needed for consumer electronics and energy storage industries. Full Production Workflow: Standardized Assembly Line from Aluminum Extrusion to Finished Products1. Aluminum Extrusion Forming the flow channel as the baseCustom dies extrude hollow flat tubes and profiles with complex internal tooth structures, enabling one-step channel forming. The material utilization rate exceeds 95%. 2. End Sealing via Friction Stir WeldingEnd plugs are pressed in at high rotational speed to form a solid-state joint in an instant, creating hermetic flow channels with pressure resistance above 1.0 MPa.3. Brazed joints for the cold plateCNC-machined inlet and outlet joints are coated with brazing paste and fitted into reserved holes of cold plates, followed by treatment in a continuous brazing furnace. Hundreds of parts can be processed in a single batch, significantly cutting energy and labor costs per unit. 4. Precision Post CNC MachiningMounting surfaces, positioning holes and nozzle end faces undergo precision milling to guarantee flatness within 0.05 mm, meeting the tight mounting requirements of IGBTs and power modules. 5. Leak Testing & Finished Goods Dispatch100% mass leak testing is implemented to ensure zero-defect delivery.

How does the embedded copper tube liquid cooling plate applied to the IGBT liquid cooling system?

Embedded copper tube liquid cooling plate plays an important role in the application of high power IGBT cooling system. The following is a related introduction: Working principle The copper tube water cooling plate uses the high specific heat capacity of water to remove the heat generated by the IGBT during operation through circulating water. The water cooling plate is usually composed of a copper tube and a metal substrate. Water flows through the copper tube. The IGBT module is installed on the metal substrate. The heat is transferred to the copper tube through the substrate and then taken away by the circulating water.

Vansim's copper tube water cooling plate manufacturing helps liquid cooling and thermal management of medical equipment

With the rapid development of science and technology, the types of medical equipment are increasing, and their applications in medical work are becoming more and more extensive. As our requirements for the accuracy and reliability of medical equipment become higher and higher, Medical equipment heat dissipation control becomes more important. Here we believe that water cooling will be a mainstream trend, with precise core heat dissipation cold heads and smaller occupied areas. Water cooling can control heat dissipation from a remote end, thereby reducing noise and improving heat dissipation performance.
