Custom Solutions for Industrial, Energy, and Aerospace Applications 

In industries where thermal efficiency directly impacts operational costs and performance, the heat exchanger stands as a critical component. Traditional copper heat exchangers, limited by machining constraints, often struggle to balance compact design with heat transfer efficiency. XiaoJiao is revolutionizing this landscape with 3D printed copper heat exchangers—a breakthrough that merges copper’s exceptional thermal conductivity (390 W/m·K) with the design freedom of additive manufacturing.

Why 3D Printed Copper Heat Exchangers Outperform Traditional Designs

Traditional manufacturing methods (welding, brazing, or machining) force compromises:

· Simple, linear flow paths restrict heat transfer surface area.

· Weld joints create weak points and increase pressure drop.

· Thick walls (minimum 1.5mm) add weight and reduce thermal response speed.

XiaoJiao’s laser powder bed fusion (LPBF) technology eliminates these limitations:

· Complex Internal Geometries: Lattice structures, spiral micro-channels (0.2mm width), and fractal flow paths increase heat transfer area by 400% without expanding overall size.

· Near-Net-Shape Production: Reduces material waste by 70% compared to CNC machining, lowering costs for high-purity copper (C10200).

· Seamless Construction: Eliminates welds, enabling operation at pressures up to 500 bar (vs. 300 bar for traditional welded exchangers).

Key Applications: Where 3D Printed Copper Shines
