AI Technical Summary

Technical Problem

Traditional heat sinks are difficult to balance strength and heat dissipation efficiency in high-power, miniaturized electronic devices, and are prone to fin vibration and root fatigue fracture in high-frequency vibration and airflow pulsation environments.

Method used

A heat sink was designed, which adopts a differentiated grid structure of fin base reinforcement section, fin body gradient section and fin tip sparse section, combined with AlSi10Mg alloy material, and forms a multi-layer structure and micron-level wrinkles by SLM printing to enhance mechanical strength and heat dissipation efficiency, and suppresses high-frequency flutter by the interlayer damping effect of the fin stigma vibration-resistant part.

Benefits of technology

It achieves structural stability in high-frequency vibration and airflow pulsation environments, while improving heat dissipation efficiency and mechanical strength, meeting the heat dissipation requirements of high-power miniaturized devices.
