Application of Embedded Heat Conduction Channel FR4 in Heat Dissipation of Car Lamp
The paper aims to explore the potential application of embedded Flame-Retardant 4 printed circuit boards (FR4)in automotive lighting heat dissipation.Through simulation,a comparative analysis and evaluation of the thermal performance between FR4 and conventional metal core printed circuit boards under steady-state operating conditions at 25 ℃ were conducted.The findings reveal that both exhibit comparable heat dissipation efficacy,with the former demonstrating superior cost-effectiveness and design flexibility.The experimental results closely align with the numerical simulations,validating the accuracy of the simulations and concurrently demonstrating that FR4 can effectively reduce the operating temperatures of automotive lamps,thereby addressing the heat dissipation challenges posed by high-power lighting systems.This research not only enhances the thermal management capabilities of automotive lighting but also broadens the scope of material selection,offering an economically viable and efficient new approach for advancing automotive lighting technology.Consequently,it holds promising engineering application prospects for the automotive industry.
