We make water blocks to cool hot parts like CPUs, GPUs, IGBTs, or battery packs. The block sits tight on the heat source. Coolant flows inside special channels. Heat moves fast to the liquid.

CNC Machining: This is the most common method used to manufacture high-precision water blocks. Intricate internal runner structures are milled directly from solid metal blocks through high-precision CNC machines, achieving extremely high dimensional accuracy and surface finish, ensuring optimal thermal contact. Brazing: A process in which a pre-machined fin structure, such as a high-density copper fin, is connected to a water block base plate by filling metal at high temperatures to create a sealed coolant runner. Brazing is suitable for manufacturing water blocks with complex fin arrays and multiple material combinations. Friction Stir Welding (FSW): An advanced solid-state joining technique that involves rubbing two pieces of metal, typically an aluminum alloy, through a high-speed rotating stir head to generate heat and mix them, creating a dense, defect-free connection. FSW is particularly suitable for manufacturing internal runners, providing superior structural integrity and pressure resistance. Skiving: Thin, dense fins are continuously shoveled from a metal block with a special tool, forming a structure that is integrated with the base. This process efficiently produces water blocks with high-density fins, reducing thermal resistance to the connection.

Micro-channels: Extremely fine channels in width and depth at the micron level are processed on the base plate of the water block. This design greatly increases the contact area between the coolant and the water block, resulting in heat dissipation at ultra-high heat flux densities (e.g., > 500 W/cm²), but often with higher pressure drops. Pin Fin Arrays: Densely arranged cylindrical or square pin fins on the base plate. These pins effectively disturb fluids and enhance turbulence, significantly improving heat transfer efficiency while balancing the pressure drop to some extent. High-Density Fins: Extremely thin, extremely dense parallel or wavy fins achieved by precision machining or brazing. This design maximizes heat transfer surface area and is suitable for high-power applications that require efficient heat dissipation over a large area.

Core Material: Copper (C11000/T2): The best thermal conductivity is the preferred material for high-performance water blocks, especially suitable for scenarios with extreme requirements for heat dissipation efficiency. Aluminum Alloy (6061/6063): Lightweight, cost-effective, suitable for applications with weight and cost requirements, and good machinability. Surface Treatment: Nickel Plating: Forms a nickel coating on the surface of the copper water block, enhancing corrosion resistance, especially when the water block is connected to an aluminum radiator or pipeline, preventing electrochemical corrosion. Passivation: Chemical treatment of stainless steel water blocks to enhance their inherent corrosion resistance. Anodizing: Targeting aluminum, it forms an oxide film that provides protection, insulation, and aesthetic effects.
