摘　　要：对流散热在散热过程中发挥着重要作用。隧道通风气流无疑为隧道LED灯具散热提供了强迫对流的作用。基于热传导、对流理论,结合铝型材挤出工艺,通过FloEFD软件模拟优化散热器散热流道设计,充分利用隧道通风气流加速对流换热效率,有效提升散热器散热效果。Convective heat dissipation plays an important role in the heat dissipation process.Tunnel ventilation airflow undoubtedly provides forced convection for tunnel LED lamp heat dissipation.Based on the theory of heat conduction and convection,combined with the extrusion process of aluminum profiles,the design of radiator cooling channel is optimized through the simulation of FloEFD software,and the tunnel ventilation airflow is fully utilized to accelerate the convective heat transfer efficiency,effectively improving the heat dissipation effect of the radiator.
