●Challenge: Combustors face extreme environments (>3000°C gas temp & high pressure). 

Traditional manufacturing requires assembling 10-100+ parts, leading to high leakage risks and limited cooling efficiency due to simple straight channels. 

●Solution: Monolithic printing of complex 3D conformal cooling channels (serpentine/honeycomb) using high-conductivity copper, ensuring heat transfer rates ~400 W/(m·K) at working temperatures. 

●Result: 

    ○Integration: Reduced part count by 80-95%, eliminating weld failures. 

    ○Performance: Increased heat exchange area by 20-60% and max heat flux tolerance by 15-30%. 

    ○Efficiency: Achieved 20-40% weight reduction and accelerated R&D iteration by 3-10 times.

●Challenge: Traditional brazing of nozzle tubes entails high leakage risks and cannot withstand extreme chamber pressures at 3000°C. 

●Solution: Monolithic printing of CuCrZr using Green Laser to create complex 0.8mm thin-walled cooling channels. 

●Result: Reduced part count by ~95% and significantly extended fatigue life under high thermal shock.
