The heat sink adopts a hexagonal honeycomb structure design, which improves heat dissipation efficiency by optimizing the airflow path and enhances structural stability. Nanofluid working medium: ethylene glycol-based nanofluid (containing Al2O3 / CuO mixed particles) is used, the thermal conductivity is increased to 1.5W / (m·K), and the viscosity is reduced by 30%. Dual circulation system: the main circulation is phase change working medium (liquid-gas), and the secondary circulation is nanofluid coolant, which realizes rapid heat extraction through heat pipe coupling.

Each layer uses nano-modified materials with different phase change temperatures, such as paraffin, graphene, boron nitride, and metal-organic framework materials. Multi-stage heat absorption is achieved through gradient phase change. The multi-layer composite phase change material is composed of at least three nano-modified materials with different phase change temperatures, and the temperature range covers -20°C to 150°C.
