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.
