Abstract：This paper aims to investigate the relationship between surface treatment of aluminum and heat dissipation efficiency.Aluminum has become a commonly used material for important components such as headlight controllers and radiators due to its excellent thermal conductivity,lightweight advantages,and good mechanical properties.However,the surface of aluminum is prone to oxidation,forming an oxide film that hinders heat transfer and affects heat dissipation efficiency.This article conducts experimental research on different surface treatment methods,such as passivation treatment,sandblasting,anodizing oxide film,etc.,and analyzes their effects on the surface characteristics and heat dissipation performance of aluminum,providing effective reference for the heat dissipation design of automotive headlight controllers.
